Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, and particularly relates to a precast wall panel for an interface wall of a prefabricated house and a connection structure thereof. Background Technique

[0002] A prefabricated building transfers a large amount of on-site operation work in the traditional construction method to a factory. Building components and fittings are processed and manufactured in the factory and transported to the construction site of the building, and are assembled and installed on-site through a reliable connection method.

[0003] In the prior art, the reliable connection between precast exterior walls is mostly realized through connection components or post-cast strips. The structure of the post-cast strip includes: steel bars protruding from the top or side of the precast wall, and the protruding steel bars are anchored in the cast-in-place part of another wall, and then the connection between the precast exterior walls is realized by pouring concrete. However, this structure has technical problems such as complex molds during production, easy bending of the protruding steel bars during transportation, complex on-site construction operations, and large concrete pouring volume. At the same time, there is a lack of longitudinal force-bearing structure at the connection between the two walls, resulting in poor overall strength of the spliced wall. Summary of the Invention

Pouring grooves are provided on one or both side surfaces in the height direction of the precast panel. A precast inner nut sleeve is provided in the pouring groove. A precast through hole is provided at the contact surface position of the precast panel being abutted, and the position of the precast through hole is opposite to that of the nut sleeve.

[0006] The precast wall panel for an interface wall of a prefabricated house as described above is such that a counterbore is provided on the plate surface of the precast panel provided with the precast through hole.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0023] Embodiment 1: Prefabricated houses are manufactured by prefabricating wall panels, floor panels and other accessories in factories, and then transporting them to the planned location of the house for rapid assembly, so that the house construction can be completed in the shortest possible time and meet the conditions for occupancy. Therefore, a very important link is the connection of prefabricated wall panels.

[0024] This example mainly focuses on the prefabricated wall panels used for the joint walls of assembled houses and their connection methods. There are three main shapes of the prefabricated panels 1 used as the wall body, in order to adapt to the connection when two walls are joined in different situations, and the following detailed descriptions are made respectively;

[0025] The first one, such as Figure 1 As shown, the thickness of the precast panel 1 is 150 mm. A casting trough 2 with a trapezoidal cross-section is provided on the left side of the precast panel 1 serving as a wall. The depth of the casting trough 2 is 60 mm, the outer opening width is 90 mm, and the inner opening is 70 mm. A prefabricated inserted inner nut sleeve 3 is provided in the casting trough 2. A prefabricated through hole 4 and a countersunk groove 5 are provided on the right side of the precast panel 1 at the position connecting another wall panel. The prefabricated through hole 4 is opposite to the position of the nut sleeve 3; an inner nut sleeve B7 for connecting to the floor slab 12 is prefabricated on the top of the precast panel 1, and side ribs (not shown in the figure) are provided at the bottom of the precast panel 1.

[0026] The second type, such as Figure 2As shown, the thickness of the precast panel 1 is 150mm. A trapezoidal casting groove 2 is provided on both the left and right sides of the precast panel 1 as a wall. The depth of the casting groove 2 is 60mm, the width of the outer opening is 90mm, and the inner opening is 70mm. A prefabricated inserted inner nut sleeve 3 is provided in the casting groove 2. A prefabricated through hole 4 and a countersunk groove 5 are provided on the left side of the precast panel 1 at the position where another wall panel is connected. The prefabricated through hole 4 is opposite to the position of the nut sleeve 3; an inner nut sleeve B7 for connecting to the floor slab 12 is prefabricated on the top of the precast panel 1, and a side rib (not shown) is provided at the bottom of the precast panel 1.

[0027] The third type, such as Figure 3 As shown, it is an optimization of the top of the prefabricated board 1 based on the first and second prefabricated boards, with the purpose of increasing the sealing between the floor 14 and the wall when the prefabricated board 1 is used as a wall. Specifically, a sunken floor support platform 8 is provided at the position where the top of the prefabricated board 1 overlaps the floor 12, and more than two built-in inner nut sleeves B7 are provided on the floor support platform 8.

[0028] The fourth type, such as Figure 4 As shown, it is a structural diagram of a prefabricated panel that does not require handover.

[0029] After learning the above four types of prefabricated panels, the structure of the above prefabricated panels intersecting and connecting is as follows

[0030] One is a picture Figure 1 and Figure 4 The connection of the prefabricated panels shown in the figure is shown in the cross-sectional diagram. Figure 5 ,at this time, Figure 4 The prefabricated panels shown are attached to Figure 1 In the prefabricated panels shown, the two prefabricated panels are at 90 degrees, and the connecting bolts 6 are inserted from the countersunk grooves 5 provided in the outer wall. The screws of the connecting bolts pass through the prefabricated through holes 4 and are screwed onto the inner nut sleeves 3 to achieve the connection between the two prefabricated panels.

[0031] Second, if Figure 6 As shown, the two prefabricated panels 1 are horizontally connected by connecting a steel rivet ring 10 on the inner nut sleeve 3. The heights of the steel rivet rings 10 between adjacent prefabricated panels 1 are different. After the two prefabricated panels 1 of the same side wall are placed in place, the ring bodies of the steel rivet rings 10 are horizontally located between the joint surfaces and are staggered. Then, connecting steel bars 11 are inserted into the steel rivet rings 10, and the vertical connection is Figure 4 Similarly, the connection is achieved by the cooperation between the connecting bolt 6 and the inner nut sleeve 3. After the connection of the connecting parts is completed, the grouting material 9 is used to fill the joint seam.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
