[0040] Referring to Figure 1 and Figure 2 , a lap joint structure of a prefabricated energy-saving building includes a building column 1 and a beam bracket 2 connected to the side wall of the building column 1. An inclined groove 11 is formed on the side wall of the building column 1 for one end of the beam bracket 2 to abut against, and the exposed end of the beam bracket 2 extending towards the top of the building column 1. A locking component 3 is arranged inside the building column 1 to limit the beam bracket 2 from detaching from the building column 1.

[0041] Referring to Figure 2 andFigure 3 , a pressure-bearing block 22 is integrally formed on the lower surface of the beam bracket 2, and a pressure-bearing notch 15 is formed on the inner wall of the inclined groove 11, so that the pressure-bearing block 22 can follow the beam bracket 2 and enter into the pressure-bearing notch 15; at the same time, the side wall of the pressure-bearing block 22 is coplanar with the side wall of the building column 1 to ensure the flatness of the outer side wall of the building column 1.

[0042] Refer to Figure 2 and Figure 3 , a number of limit bolts 221 penetrate through the pressure-bearing block 22, and a settlement groove 222 for the end of the limit bolt 221 to enter is formed on the pressure-bearing block 22, so as to ensure the flatness of the surface of the pressure-bearing block 22. All the limit bolts 221 are threadedly connected to the building column 1 to realize the fixed connection between the pressure-bearing block 22 and the building column 1.

When the insertion block 311 enters into the plugging groove 321, the position of the locking rod 32 can be restricted. When the insertion block 311 enters into the embedding groove 131, the limit rod 31 abuts against the side wall of the locking rod 32 away from the beam bracket 2, and the end of the locking rod 32 away from the limit rod 31 enters into the locking groove 21, thereby restricting the beam bracket 2 from disengaging from the inclined groove 11.

[0046] Refer to Figure 2 and Figure 5, a fixing plate 312 is integrally formed at one end of the limiting rod 31 away from the locking rod 32.

[0049] Referring to Figure 1 and Figure 2 , an extension plate 161 is integrally formed on the side wall of the second support plate 16, and the extension plate 161 covers the pressure-bearing notch 15. A plurality of fastening bolts 162 are inserted through the extension plate 161, and all the fastening bolts 162 are threadedly connected to the housing column 1 to realize the fixed connection between the second support plate 16 and the housing column 1.

[0050] Referring to Figure 1 and Figure 2 , a second tension plate 17 is fixedly connected to the side wall of the housing column 1 by bolts, and the first tension plate 24 is fixedly welded to the second tension plate 17. A plurality of reinforcement plates 241 are fixedly welded between the first tension plate 24 and the second tension plate 17, and all the reinforcement plates 241 are distributed at intervals along the length direction of the first tension plate 24.

A plurality of stabilizing plates 243 are fixedly welded between the adjacent first dispersion plate 242 and the second dispersion plate 171, and all the stabilizing plates 243 are distributed at intervals along the length direction of the first dispersion plate 242.

[0052] The implementation principle of an assembled energy-saving building lap joint structure in an embodiment of the present application is as follows:

[0053] When transportation is required, the volume and mass of the bulk housing columns 1 and beam brackets 2 are small, providing convenience for the rapid transfer of the housing columns 1 and beam brackets 2.

[0054] When the housing columns 1 and beam brackets 2 need to be assembled, insert the insertion block 311 into the insertion slot 321 to fix the locking rod 32 inside the sliding slot 12; slide the beam bracket 2 along the length direction of the inclined slot 11 and insert it into the inclined slot 11, and the pressure-bearing block 22 is inserted into the pressure-bearing notch 15. Pull out the limit rod 31 so that the insertion block 311 disengages from the insertion slot 321, and the locking rod 32 gradually moves into the locking slot 21 under the action of gravity. Then slide the limit rod 31 along the length direction of the limit slot 13 and insert the insertion block 311 into the embedding slot 131. By the limit rod 31 abutting against the locking rod 32, it is ensured that the locking rod 32 is stably abutted inside the locking slot 21, thus realizing the rapid assembly of the housing columns 1 and beam brackets 2.
