[0002] Nowadays, in order to improve construction efficiency and avoid construction pollution, the use of prefabricated building roofs and walls is becoming more and more widespread. In the prior art, prefabricated assembled roofs and walls are mostly connected by bolts and connecting plates. The connecting plates are connected to the embedded steel plates in the prefabricated assembled roofs and walls by bolts. However, this connection requires opening a large number of bolt holes, which makes the processing process complicated. In addition, multiple bolt holes need to be aligned at the same time during the splicing process, which greatly increases the difficulty of operation.

[0003] For example, a Chinese utility model patent disclosed in China with publication number CN217480493U and authorization announcement date September 23, 2022 discloses an insertion-type connection structure between an assembled building wall and a building roof, comprising a wall-insertion part and a connecting top fixedly connected to the wall-insertion part, the wall-insertion part is connected to the connecting top, the wall-insertion part has at least one connecting protrusion, the connecting protrusion can be longitudinally inserted into the wall of the assembled building and plug-connected with the corresponding hole in the wall, the connecting protrusion has a central blind hole, the connecting top has at least one connecting top plate, the connecting top has a keel insertion space, and the connecting top plate has a bolt through hole.

[0004] However, in actual use, although the above patent facilitates the assembly of prefabricated building walls with various building roofs, in actual operation, it is necessary to align the reserved bolt holes on the building roof with the bolt through holes on the connecting plate so that the bolts can smoothly fix the roof to the wall. Connecting in this way greatly increases the difficulty of operation, thereby reducing construction efficiency. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connection structure between a building roof and a wall, comprising a roof and a wall, wherein the two ends of the bottom of the roof are respectively fixedly connected with a plurality of plug-in columns, the top of the wall is fixedly connected with a plurality of fixed blocks, a groove is provided in the middle of the fixed block, four movable blocks are provided in the groove, the four movable blocks are spliced ​​together into a cylindrical shape, a plurality of connecting rods are fixedly connected to the outer wall of the movable block, the connecting rods are slidably connected to the fixed block, a first arc groove is provided at one end of the top of the movable block, and the four first arc grooves are spliced ​​together into a conical groove shape.

[0007] Preferably, a conical head is fixedly connected to the bottom of the plug-in column.

[0008] Preferably, the fixing block is provided with a plurality of sliding grooves on the side wall of the groove, and the sliding grooves are slidably connected to the connecting rod.

[0009] Preferably, a second arc groove is provided at one end of the bottom of the moving block, and four of the second arc grooves are spliced ​​together to form a cylindrical shape.

[0010] Preferably, the groove is cylindrical.

[0011] Preferably, a rubber pad is provided on the inner wall of the groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model installs the fixing block on the top of the wall, so when the top plate is connected to the wall, the top plate is fixed by simply inserting the plug-in column on the top plate between the four movable blocks on the fixed block, wherein the first arc groove provided on the movable block not only makes it easier to insert the plug-in column, but also squeezes the movable block during the plug-in process of the plug-in column, so that the movable block moves toward the side wall of the groove, and when the movable block is tightly attached to the side wall of the groove, the top plate is fixed. In this way, the top plate can be quickly positioned and fixed, which greatly improves the construction efficiency and eliminates the step of aligning multiple bolt holes during splicing, thereby speeding up the splicing speed.
