Ding Qi and Zhuang stood at both ends, each holding a thick rope, and everyone shouted a trumpet, pulling up the triangular girder little by little. After the girder is erected on the right, the people on the left and right sides pull the rope to keep the girder still, and the original people on the beam form a group of people, pull up a 20-meter-long purlin, erect it on the top of the triangular girder and the right wall, nail it, and preliminarily fix the girder.

Then continue the work of the upper beam of another girder, and after it is fixed, pull up another 20-meter-long purlin between the two girders, which is basically fixed to the two girders.

After the girder is erected, two larch trees with a thickness of 40 centimeters are respectively supported as pillars under each girder, and the connection between the pillar and the girder is connected with a mortise and tenon structure, so that the beam frame structure of the whole hall is more solid.

Next, Jing's group of carpenters continued to pull the purlins up, nine purlins on one side, a total of eighteen purlins were erected, and the time of the day had passed. This is the structure required for the large wooden frame of the seven purlins, and the house will be relatively strong and durable.

In fact, according to the requirements for building houses in rural areas in the past, a house 60 meters long and 30 meters wide must be erected with at least six frames, three beams on the left and right, and a column must be added under the middle of each beam.

The main reason for erecting so many girders is that there were no too long timbers before, but now in primitive times, there are many timbers of various years, and there are all kinds of timbers. Moreover, Ding Qi asked Jing to find tall and straight larches and spruces, and there are many spruces with a length of more than fifty meters, which are more than enough to use as a whole beam.

The next day, the erection of the rafters began.

According to the Pythagorean theorem, the length of the entire roof is 15.13 meters, and four rafters are needed, so the length of each rafter is 3.2 meters, and the extra part is to ensure that it has enough length to be laid between the upper and lower purlins. The distance between each rafter is 30 centimeters, and after the dense laying, two days have passed.

At this time, another building material for the house that needed to be laid on the roof: reeds, had already been woven under the control of the stag elders.

The material used for weaving reeds is reeds, which were collected from the lake last winter and stacked to dry under the slope.

Some time ago, when laying the foundation of the main hall, Ding Qi had already calculated the size of the roof of the main hall. Then he arranged for people to circle a piece of land from the pile of dry reeds under the dirt slope and began to weave reeds.

According to the length of the collected reeds is about 3.5 meters, the size of the reeds is 10 meters wide and 15.2 meters long, and the weaving method is similar to the principle of weaving bamboo sieves.

The woven bamboo sieve is pressed one to one, and the woven reed is pressed two to one, with a thickness of a layer of reeds, less than half a centimeter. In the weaving process, it is also necessary to consider how to splic, continue the reed, and finally how to close the mouth, these are very important, if you don't do it well, the reed will be considered a waste.

When Ding Qi was a child, he had only seen how others made it up, but he didn't know how to close it. At that time, I was greedy for fun, and I played with the children on the rolled up reeds, and I didn't pay attention to how people closed their mouths. At this time, in the case that no one can guide him, Ding Qi can only explore with everyone, such as the method of backing and closing the edges.

It is made up according to the dimensions above

The reeds are not too heavy and can be pulled to the top of the main hall. But if it is made according to 60 meters x 15 meters, it will be a lot of work! I guess I can't hang it!

All of them are calculated, and a total of twelve 10 m x 15 m reeds are needed, but Ding Qi was afraid that a layer of reeds would be a little thin, so he asked everyone to make up an extra group, a total of 24 reeds. There are a lot of people, and the speed of making up is not slow, and the reeds are ready three days in advance.

In the past, when building a house in the village, the homeowners were reluctant to go outside to buy reeds, so they collected the reeds by themselves, and then asked someone to make them when building the house, so that they could catch up with the progress of building the house, saving time, effort and money.

Before preparing to lay the reeds, Ding Qi sent fifty or sixty people to come over to help, preparing to lay the reeds, mud, mud, and tiles. Don't look at the small content, but the amount of work is really not small, Ding Qi doubts whether there are enough manpower.

First, the rolls of reeds are tied up with long ropes, and then dragged up by the people on the scaffolding, first laid on one layer, then hoisted up another roll, and continued to spread the second layer. In this way, two groups of twenty-four rolls of reeds have been spread on the rafters of the roof in half a day, and the hall below suddenly darkened.

While the people on the roof are laying the reeds, the people on the scaffolding continue to hang the big red tiles up, while the people below have begun to pack the reconciled mud in the rattan basket, tie the rope, and then drag the people above to pour the mud on the bottom of the reeds, and the people will spread out and smooth the mud from left to right with a wooden trowel, and then spread the big red tiles on the mud from left to right.

The big red tile is actually a large red flat tile, with a protrusion of about one centimeter above the tile, commonly known as a hanging hook, which is used to hang in the mud to prevent the tile from being blown off by the wind or sliding down by itself. These tiles are fired in advance between the bricks and stacked under the high scaffolding, so that the personnel can keep the tiles on the scaffolding and roof.

After the big red tile is laid with a layer, continue to lay the mud and smooth it, and then put a tile against the red tile below, stagger half to the right and press it on the second half of the tile below, and press the upper half on the mud, and buckle the hook into the mud.

This is called the staggered joint paving method, and the same as the staggered joint masonry method of building the wall, the vacant half of the mud can be pasted with half a piece of red tile. Then continue from left to right, stacking pieces on the mud surface, close together.

According to this paving method, it took a total of two full days to complete the paving.

After the roof was built, Ding Qi, with the help of the Shathey mason team, used wooden trays and wooden trowels to teach everyone how to paint the walls of the hall with white plaster. Now there is no cement mortar, only lime mortar can be painted and painted all over the four walls.

At this time, the four walls of the city are about to be completed with the joint efforts of everyone, and the process of laying red bricks on the upper part of the city wall is now underway. The lime mixing soil has been tamped by everyone, and stepping on it is the same as stepping on a stone. The red bricks are staggered in two layers to ensure that the entire base surface is stronger.

The six-meter-high and three-meter-wide walls towering over the ground make one feel small. There are many people on the city wall, and the busy flow of people under the city wall is also endless, constantly transporting bricks, earthwork, wood, and lime materials for the construction of the city wall, ensuring that the entire construction project can be effectively operated.

At the main entrance, an arched door has been formed, supported by an arched tire. The arch is five meters high, and there is another meter high brick on top

The blocks are built and arc-shaped. There is no plan to build another gatehouse above the arch for the time being, which would be a bit of a waste of time. For Ding Qi, it's a fancy thing, and it's not too late to build it when the tribe is strong.

However, it is still necessary to build four watchtowers at the corners of the four city walls, as well as an alarm bell tower. As for the method of making the bell, Ding Qi had already made a decision in his heart when he met the Gurung tribe: the lost wax method!

Bee hives are used to refine beeswax, beeswax is used to make models, and some things that are difficult for others to do are molded through beeswax, and then cast with bronze juice.

When the Gurung tribe joined the Ding tribe, they had already raised two boxes of bees according to the method described by Ding Qi. After coming to the Ding tribe, he went to the forest to look for more bee colonies under Ding Qi's arrangement, and during this period of time, a total of eight boxes of bees were found, all of which were placed on the grassland below the soil slope for natural feeding. These bees would form the basis for the development of Tinch's beekeeping, as well as the mass production of some intricate bronzes.

Inside the arch, the construction of the gate has not yet begun, the gate is more complicated to build, and there is no suitable wood for the time being, so it can only be replaced by a wooden fence to block the beasts.

Now, most people have focused their efforts on building inside the city. Under Ben's command, they began to build the two cross-shaped avenues twenty meters wide. The construction method of the road foundation and the city wall foundation is the same, that is, the same lime powder is used to stir the loess, and then rammed. The foundation is one meter deep, and after it is rammed, a layer of bricks is laid on top of it, and the brick joints are blocked with floating soil. The first two avenues were built to facilitate the transportation of building materials.

The large square at the intersection of the two avenues, rammed more solidly, is facing the main hall, sixty meters long and sixty meters wide, giving people a rather grand momentum.

And the big hall that rises from the ground attracts many people to watch every day when work is done. The whitewashed lime walls, under the burning of seven or eight bonfires in the main hall, quickly condensed and became very solid, and under the light, the whole hall became very bright.

Not to mention the wide doors and open windows, although it is only a plain hall, it makes people feel the urge to worship.

After the main hall, the two avenues and the south gate were built, Ben took people to build the residential areas on both sides.

The first city of the primitive era can only be brought back to life if people live in it. Unlike Tucheng, the defense of the red brick city wall built now is absolutely first-class, and those who live in it will have a great sense of security.

At the planned location, the Ben Ming people began to dig the foundation, sprinkle lime and mix the soil, and then build a wall on top of it to build a house. As soon as the house is built, according to the plan, all the people can be moved in.

At the same time, a drainage ditch was dug between each row of houses for the treatment of wastewater and sewage from daily life.

Moreover, in each of the four areas of the city, a deep well was dug as a place for everyone's daily life, which was more convenient for everyone's daily needs.

After putting the last brick on the walls into place, the first castle of the primitive era was built. Although it was only a frame, all the people involved in the construction of the city walls and the buildings inside the city stood in the square, cheering loudly and jumping with joy, venting their excitement and excitement in their hearts.

And this moment will forever be recorded in history!
