Detailed Description

The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1-2, the connection structure of prefabricated wall body that this application discloses, including last wall body 1 and lower wall body 2, go up wall body 1 and run through respectively on the 2 direction of height of wall body down and seted up a plurality of perforation 3 and a plurality of perforation 4 down, when last wall body 1 splices with wall body 2 down, a plurality of perforation 3 and a plurality of perforation 4 one-to-one switch-on down go up, go up perforation 3 and perforation 4 down can be round hole also can flat hole, go up and be provided with between wall body 1 and the lower wall body 2 and be used for carrying out the positioning mechanism who fixes a position to the concatenation of the two. Positioning mechanism includes integrated into one piece in the high ring 10 of wall body 2 up end down, and high ring 10 and the coaxial setting of lower perforation 4, and high ring 10 inner wall flushes with 4 pore walls of lower perforation specifically when wall body 2 down is made in the shaping, goes up 1 terminal surfaces of wall body and offers the slot 11 with the high ring 10 adaptation of pegging graft, and is specific, and high ring 10 outer wall sets up to the inclined plane, slot 11 and inclined plane adaptation.

Therefore, when the upper wall body 1 and the lower wall body 2 are assembled, the upper wall body 1 is lifted firstly, so that the upper wall body 1 and the lower wall body 2 are gradually closed until the height ring 10 on the lower wall body 2 is partially embedded into the slot 11 on the upper wall body 1, then the upper wall body 1 is slowly put downwards, and when the upper wall body 1 is put downwards in place, the upper wall body 1 and the lower wall body 2 can be assembled quickly; in the process, the height ring 10 with the conical outer surface can play an effective guiding and positioning role for the alignment of the upper wall body 1 and the lower wall body 2, so that the upper wall body 1 and the lower wall body 2 after splicing are higher in uniformity.

As shown in fig. 1-2, the joint portions of the upper wall 1 and the lower wall 2 are both provided with a placement groove 5 arranged along the joint extending direction, two placement grooves 5 on the same side are provided with a water stop belt 6 arranged along the joint extending direction, the water stop belt 6 is a rubber water-swelling water stop belt 6, and the upper wall 1 or the lower wall 2 is provided with a locking mechanism for locking the water stop belt 6 in the placement grooves 5. The locking mechanism comprises a pressing plate 7 which is arranged on one side of the waterstop 6 far away from the lower through hole 4, a convex edge 8 which is used for clamping the pressing plate 7 on the waterstop 6 is arranged on the groove wall of one side of the placement groove 5 far away from the joint, the cross section of the convex edge 8 is in a right-angled triangle shape, and the bevel edge of the convex edge is tightly abutted to the pressing plate 7.

After the upper wall body 1 and the lower wall body 2 are assembled, the water stop belts 6 are inserted into the arrangement grooves 5, so that the water stop belts 6 block the seams, then the pressing plates 7 are inserted into the arrangement grooves 5 from the openings at one ends of the arrangement grooves 5 along the extending direction of the seams, and the pressing plates 7 enable the water stop belts 6 to be pressed at the seams through the inclined planes of the two oppositely arranged convex edges 8 on the arrangement grooves 5. The tight degree of abutting between the water stop belt 6 and the joint is effectively improved, and the water resistance performance is better.

In order to further improve the sealing effect of the water stop belt 6 on the joint, as shown in fig. 1-2, the upper wall 1 and the lower wall 2 are filled with a concrete layer 9 in the placing groove 5, the concrete layer 9 is positioned on one side of the pressing plate 7 far away from the water stop belt 6, and one side of the concrete layer 9 far away from the joint is flush with the same side of the upper wall 1 and the lower wall 2. Therefore, after the concrete layer 9 is condensed, the concrete layer 9 tightly presses the pressing plate 7 and the water stop belt 6 in the placing groove 5, and the waterproof performance is better.

In order to further improve the structural performance of the spliced upper wall 1 and the spliced lower wall 2, as shown in fig. 1, the upper wall 1 and the lower wall 2 are respectively and commonly provided with a filling layer 12 in the upper through hole 3 and the lower through hole 4, and the filling layer 12 is made of reinforced concrete or heat insulation cotton. When the filling layer 12 is made of reinforced concrete, the bending resistance of the upper wall body 1 and the lower wall body 2 after splicing can be improved; when the filling layer 12 is made of heat insulation cotton, the upper through holes 3 and the lower through holes 4 are flat holes, so that the heat insulation performance of the spliced upper wall body 1 and the spliced lower wall body 2 can be improved. In the embodiment of the application, the filling layer 12 is made of reinforced concrete.
