Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, and particularly relates to a precast wall panel for the same-side wall surface 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 end 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 a longitudinal force-bearing structure at the connection between the two walls, resulting in poor overall strength of the spliced wall. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a precast wall panel for the same-side wall surface of a prefabricated house and a connection structure thereof with reliable connection and good structural stability, which can overcome the above technical problems.

[0005] The purpose of the utility model is realized through the following technical solutions:

[0006] A precast wall panel for the same-side wall surface of a prefabricated house includes a single precast panel matching the height of a single storey of the house. On one or both side surfaces in the height direction of the precast panel, there are two or more groups of steel rivet rings, and the heights of the steel rivet rings between adjacent precast panels used in the prefabricated house are different.

[0007] The precast wall panel for the same-side wall surface of the prefabricated house described above is such that the steel rivet ring is composed of a ring body and a connecting rod. An internal nut sleeve is precast in the precast panel, and a thread is processed on the connecting rod of the steel rivet ring, and the connecting rod is connected to the internal nut sleeve.

[0010] The precast wall panel for the same-side wall of the aforementioned prefabricated house is as follows: when the precast panel is used as the inner wall of the house, two or more built-in internal nut sleeves B for fixing the house roof slab are provided along the wall direction at the top of the precast panel; when the precast panel is used as the outer wall of the house, a floor support platform is provided along the wall direction at the top of the precast panel, and two or more built-in internal nut sleeves B are arranged on the floor support platform.

[0011] The precast wall panel for the same-side wall of the aforementioned prefabricated house is as follows: when the precast panel is used as the outer wall of the second floor of the house, a concave bolt insertion groove is provided in the thickness direction of the lower part of the precast panel, and a vertically downward precast through hole is provided on the side wall of the bolt insertion groove.

[0012] The connection structure of the precast wall panel for the same-side wall of the prefabricated house includes connecting reinforcing bars.

The precast wall panel has a simple structure, a flat surface of the precast panel, simple and reliable later assembly connection, and can conveniently seal the splicing joint. For the connection of two precast panels located on the same plane, prefabricated steel riveting rings are used.

[0030] Hereinafter, preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for explaining the present utility model and not for limiting the protection scope of the present utility model.

[0031] Example 1. The prefabricated house is constructed by prefabricating wall panels, floor slabs and other accessories in the factory and then transporting them to the planned location of the house for rapid assembly, so as to complete the house construction in the shortest possible time and meet the occupancy conditions. Therefore, an important link is the connection of prefabricated wall panels.

[0032] This example mainly focuses on the structure and connection method of prefabricated wall panels for the same-side wall of a prefabricated house. The shape of the prefabricated panel 1 as the wall has four main types, which will be described in detail as follows;

[0033] First, as Figure 1 shown, to realize the connection of two prefabricated panels 1 on the same-side wall, steel riveting rings 2 are prefabricated on one or both sides in the width direction of the prefabricated panel 1. The heights of the steel riveting rings 2 used between adjacent prefabricated panels 1 in the prefabricated house are different. An internal nut sleeve B7 for connecting the floor slab 14 is prefabricated at the top of the prefabricated panel 1, and side reinforcement bars (not shown in the figure) are provided at the bottom of the prefabricated panel 1. After the two prefabricated panels 1 on the same-side wall are placed in place, the ring bodies of the steel riveting rings 2 are horizontally located between the splicing surfaces and are staggered. Then, connecting reinforcing bars 10 are inserted into the steel riveting rings 2, and a formwork is set up and high-strength grouting material is used to grout into the splicing seam of the two prefabricated panels 2 to form a cast-in-place body. To further enhance the waterproof property, a building sealant layer 12 and a foam cushion layer 13 are filled into the splicing seam of the two spliced prefabricated panels 1 from the outside to the inside. The side reinforcement bars at the bottom of the prefabricated panel 1 are trimmed to be parallel to the ground or welded to the ground steel mesh after the wall surface of the house is assembled, and then the house floor is cast in place so that the side reinforcement bars are located in the ground cast-in-place layer 5, thereby further improving the stability of the spliced wall panels.

[0034] Second, as Figure 2 shown, to realize the connection of two prefabricated panels 1 on the same-side wall, a pouring groove 4 is opened on one or both sides in the width direction of the prefabricated panel 1. The thickness of the prefabricated panel 1 is 150 mm. A pouring groove 3 with a trapezoidal cross-section is provided on the left side of the prefabricated panel 1 as the wall. The depth of the pouring groove 32 is 60 mm, the outer opening width is 90 mm, and the inner opening is 70 mm. At the same time, an internal nut sleeve 3 with its port located in the pouring groove 4 is embedded in the prefabricated panel 1, and a steel riveting ring 2 is connected to the internal nut sleeve 3. The steel riveting ring is composed of a threaded rod and a ring body. The heights of the steel riveting rings 2 used between adjacent prefabricated panels 1 in the prefabricated house are different. At the same time, an internal nut sleeve B7 for connecting the floor slab 14 is prefabricated at the top of the prefabricated panel 1. As Figure 5 、 9As shown in FIGS. 9 and 10, after the two precast slabs 1 on the same side wall are placed in place, the ring bodies of the steel rivet rings 2 are horizontally located between the splicing surfaces and arranged staggeredly. Then, connecting reinforcing bars 10 are inserted into the steel rivet rings 2. A formwork is set up and high-strength grouting material is used to grout the splicing seams of the two precast slabs 1 and the pouring grooves 4 to form a cast-in-place body. To further enhance waterproofness, a building sealant layer 12 and a foam cushion layer 13 are filled into the splicing seams of the two spliced precast slabs 1 from the outside to the inside. The side reinforcement bars at the bottom of the precast slab 1 are trimmed to be parallel to the ground or welded to the ground steel mesh after the assembly of the house wall surface is completed, and then the house floor is cast in place so that the side reinforcement bars are located in the ground cast-in-place layer 5, thereby further improving the stability of the spliced wall panels. In the overlapping area between the floor slab 14 and the precast slab 1, a precast through-hole B16 is provided. The head of the connecting bolt 15 is located on the floor slab 14, and the screw rod passes through the precast through-hole B and is connected to the internal nut sleeve B7. At the same time, the overlapping joint is grouted with concrete to realize the connection between the floor slab 14 and the precast slab 1.

[0035] The third type, as Figure 3 shown, is an optimization of the top of the precast slab 1 based on the second type of precast slab, aiming to increase the sealing performance between the floor slab 14 and the wall when the precast slab 1 is used as a wall. Specifically, a sunken floor support platform 6 is provided at the position where the floor slab 14 overlaps the top of the precast slab 1, and two or more internal nut sleeves B7 are provided on the floor support platform 6. At this time, the connection between the floor slab 14 and the precast slab 1 is as Figure 7 shown.

[0036] The fourth type, as Figure 4 shown, is a further supplement to the above three precast slab structures, mainly to adapt to the connection of precast slabs for walls of buildings with two or more floors. The main difference is to add a connection structure convenient for the precast slabs on the first floor. Specifically, a bolt insertion groove 8 is provided on the precast slab 1. The bolt insertion groove is formed by partial indentation in the thickness direction of the precast slab, and a precast through-hole 9 parallel to the height direction of the precast slab is provided in the bolt insertion groove 8.

[0037] During use, as Figure 8 shown, a sunken floor support platform 6 is provided on the lower precast slab 1, and a vertical internal nut sleeve B7 is precast on the floor support platform 6. A precast through-hole B16 is provided in the overlapping area between the floor slab 14 and the precast slab 1. The end of the floor slab 14 overlaps on the floor support platform 6, and the screw rod of the connecting bolt 15 passes through the precast through-hole 9 and the precast through-hole B16 and is connected to the internal nut sleeve B7.
