[0041] Example 1

[0042] The basics are as follows: Figures 1-5 As shown: a prefabricated assembled house building, including a base 1, a top base 3 and several wall components 2, the several wall components 2 are connected in sequence to form a multi-story building. The wall component 2 includes a guide component and several walls 202. The guide component of the bottom wall component 2 is set on the top of the base 1. The guide component includes a support 201. The support 201 is provided with several guide pipes 203. The length of the guide pipes 203 is greater than the height of the support 201. The top of the base 1 is provided with several steel bars 204 corresponding to the guide pipes 203. During installation, the support 201 is installed on the top of the base 1 and the steel bars 204 pass through the guide pipes 203. Concrete is poured into the guide pipes 203 up to the height of the support 201. The length of the steel bars 204 is greater than the length of the guide pipes 203.

[0043] The wall 202 is provided with a plurality of guide channels 205 corresponding to the guide pipes 203. The diameter of the guide channel 205 is larger than that of the guide pipes 203, and the guide pipes 203 can be inserted into the guide channel 205. A correction component is provided in the guide channel 205. The correction component includes a correction telescopic ring 207. Support blocks 209 are symmetrically provided on both sides of the correction telescopic ring 207. The inner wall of the guide channel 205 is provided with a groove 206 corresponding to the support block 209. The support block 209 is located in the groove 206 and the support block 209 slides vertically with the guide channel 205 through the groove 206.

[0044] The top of the straightening expansion ring 207 is fixedly connected to the top of the guide channel 205. The diameter of the ring opening at the end of the straightening expansion ring 207 near the top of the guide channel 205 is the same as the diameter of the reinforcing bar 204. The diameter of the ring opening at the end of the straightening expansion ring 207 near the bottom of the guide channel 205 is larger than that at the other end of the straightening expansion ring 207. The straightening expansion ring 207 is foldable and conical.

[0045] Wall connectors are provided between walls 202 and several walls 202 are combined to form a rectangular body. The topmost wall component 2 is located at the bottom of the top seat 3. The bottom of the top seat 3 is provided with several fixing holes corresponding to the positions of the reinforcing bars 204. The top seat 3 can be inserted into the reinforcing bars 204 through the fixing holes and concrete can be poured to fix it to the top of the wall component 2.

[0046] The specific implementation process is as follows: During assembly, the base 1 is first fixed to the ground, and then the support 201 is set on the base 1. During the setting, the steel bars 204 are passed through the guide pipes 203 on the support 201 in sequence, and concrete is poured up to the height of the support 201. Then the wall 202 is installed. When installing the wall 202, the guide channel 205 of the wall 202 is aligned with the position of the guide pipe 203, and then the wall 202 is lowered. Since the height of the guide pipe 203 is lower than the length of the steel bars 204, the guide channel 205 will not contact the guide pipe 203 at the beginning. As the wall 202 is lowered, the guide channel 205 will contact the guide pipe 203, and the guide channel 205 will gradually be fitted over the wire conduit.

[0047] Simultaneously, the guide pipe 203 will come into contact with the straightening component. With the contact of the guide pipe 203 and the gradual downward movement of the wall 202, the support block 209 will move vertically upward along the slide 206 within the guide channel 205, continuously limited by the top of the guide pipe 203. Due to the design of the straightening expansion ring 207, the diameter of the ring opening of the straightening expansion ring 207 will continuously decrease as the support block 209 moves upward. Furthermore, because the length of the reinforcing bar 204 is greater than the height of the guide pipe 203, the top of the reinforcing bar 204 will first contact the upper part of the straightening expansion ring 207 and be... Under the action of the corrective expansion ring 207, a certain degree of correction and positioning is achieved. At the same time, as the wall 202 is gradually lowered, the diameter of the ring opening of the corrective expansion ring 207 is continuously reduced, which will cause the steel bar 204 with bending amplitude to move closer to the center under the restriction of the expansion ring, thereby achieving the straightening effect of the steel bar 204, reducing the bending of the steel bar 204 inside the wall 202, thus reducing the poor support effect. At the same time, when the wall 202 is completely lowered, the top of the steel bar 204 will be locked and fixed by the corrective expansion ring 207, and the upper part of the steel bar 204 will be corrected to the center under the action of the corrective expansion ring 207.

[0048] Subsequently, the concrete is poured into the guide pipe 203, and then the concrete will flow into the guide channel 205 along the guide pipe 203, and the wall 202 and the support base 201 are assembled, and the adjacent walls 202 are assembled through the wall 202 connectors, and the wall 202 top can be designed according to the different layers of buildings, and the wall 2 is installed on the wall 202 top according to the above-mentioned technology, and finally the top seat 3 is installed on the top of the top wall 202, and the fixing port of the top seat 3 is corresponded to the position of the steel bar 204, and the concrete is poured to realize the assembly of the building.

[0056] At the same time, due to the design of the injection pipe, when the concrete contacts the output port on the guide pipe 203, the concrete will flow into the injection pipe, and due to the inclined design of the injection pipe, the concrete will be squeezed into the injection pipe under the action of gravity after the concrete in the main guide pipe 203 is fully poured, thereby flowing into the adjacent guide pipe 203 along the injection pipe, thereby realizing the sequential pouring of the concrete, and the concrete pouring of the entire wall 202 can be realized through one concrete pouring point, which is simple, convenient and easy to operate.
