Description

Technical Field

[0001] The utility model relates to the technical field of assembled building construction, in particular to an assembled prefabricated wall panel installation structure. Background Art

[0002] Various prefabricated components are used in prefabricated buildings. Prefabricated wall panels are the most commonly used components. Prefabricated wall panels are pre-made in the factory and then transported to the construction site for assembly. This type of wall panel solves the problem of complex wall construction. These wall panels are mostly connected by assembly. In order to ensure the accuracy and stability of the connection, some positioning parts and fasteners are usually used. These parts are easily exposed during assembly, and the integrity of the wall is difficult to control.

[0003] For example, for residential prefabricated walls, whether they are interior or exterior wall panels, on the side facing the interior, after installation, we do not want to leave obvious protruding points of connecting fasteners or fasteners on the wall to avoid affecting the subsequent wall decoration construction. Summary of the invention

[0004] The utility model aims to provide an assembled prefabricated wall panel installation structure in view of the problems existing in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An assembled prefabricated wall panel installation structure comprises a plurality of prefabricated wall panels which are spliced ​​in sequence, wherein the side walls of the prefabricated wall panels are respectively provided with assembly protrusions and / or assembly positioning holes, and the assembly protrusions and assembly positioning holes of adjacent prefabricated wall panels are plugged together; the prefabricated wall panels are provided with reserved grooves at the side wall edges near the assembly protrusions or the assembly positioning holes, and the reserved grooves are provided with connecting ears, which are pre-buried in the prefabricated wall panels and do not extend beyond the reserved grooves. When adjacent prefabricated wall panels are assembled, the adjacent connecting ears are connected by fastening components, and closed fillers are provided in the reserved grooves.

[0007] The assembled prefabricated wall panel installation structure improves the splicing structure of the prefabricated wall panels to enable more convenient and firm connection, thereby improving the connection and installation stability of the assembled wall panels, reducing on-site construction time and subsequent reinforcement construction. This wall panel structure can be used for indoor installation in buildings, and has higher stability and construction efficiency than traditional indoor brick walls.

[0008] When adjacent prefabricated wall panels are butted, the connecting lugs will correspond to each other one by one, and then the connection of the fastening assembly can make the adjacent prefabricated wall panels better connected together, so that the two are connected more tightly. The setting of the reserved groove can accommodate the connecting lug and the fastening assembly, and prevent the connecting lug from being exposed from the surface of the prefabricated wall panel. The setting of the closed filler can block the reserved groove, which can not only cover the connecting lug and the fastening assembly, but also make the surface of the prefabricated wall panel after splicing smooth, which is convenient for subsequent wall construction.

[0009] Furthermore, a positioning sleeve is embedded in the prefabricated wall panel, and the internal space of the positioning sleeve is the assembly positioning hole; a first connecting rib is provided at the end of the positioning sleeve, and the first connecting rib is connected to the steel bar system in the prefabricated wall panel, and the inner end of the connecting ear is connected to the positioning sleeve.

[0010] The assembly protrusion and the prefabricated wall panel are an integrally formed prefabricated structure, a second connecting rib connected to a steel bar system in the prefabricated wall panel is provided in the assembly protrusion, and the inner end of the connecting ear is connected to the second connecting rib.

[0011] Through such an arrangement, the force of the connecting ear piece can be transmitted to the steel bar system, so that the entire prefabricated wall panel shares the force and avoids excessive local force.

[0012] Furthermore, the number of the assembly positioning holes or the assembly protrusions on the same side is two, arranged vertically, and the number of the reserved grooves is four or two, arranged diagonally.

[0013] Furthermore, the fastening assembly includes a spacer block disposed between a pair of connecting ears, and a bolt or a screw rod or a pin connecting the connecting ears and the spacer block.

[0014] Furthermore, the closed filler is a rubber block, a mud block or a mortar applied on site.

[0015] Furthermore, an adhesive layer is provided between adjacent prefabricated wall panels.

[0016] In some embodiments, a side support auxiliary bracket is also included, which includes a right-angle support plate, a hinged seat is provided on the right-angle support plate, and the hinged seat is connected to an oblique support rod, one end of the oblique support rod abuts against the prefabricated wall panel or is temporarily connected to the connecting ear.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. The prefabricated wall panel installation structure improves the splicing structure of the prefabricated wall panels, so that it can be connected more conveniently and firmly, thereby improving the connection and installation stability of the prefabricated wall panels, reducing the on-site construction time and subsequent reinforcement construction. This wall panel structure can be used for indoor installation in buildings, and its stability and construction efficiency are higher than those of traditional indoor brick walls; 2. When adjacent prefabricated wall panels are butt-jointed, the connecting ears will correspond one by one, and then the connection of the fastening components can be used to allow the adjacent prefabricated wall panels to be connected. The panels are better connected together, and during the tightening process of the fastening components, the prefabricated wall panels will be closer to each other, making the connection between the two tighter; 3. The setting of the reserved groove can accommodate the connecting ear and the fastening component, avoiding the connecting ear from being exposed from the surface of the prefabricated wall panel, and in the later stage, there will not be many protrusions on the surface of the prefabricated wall panel after splicing; 4. The setting of the closed filler can block the reserved groove, which can not only cover the connecting ear and the fastening component, but also make the surface of the prefabricated wall panel after splicing smooth, which is convenient for subsequent wall construction.

[0029] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] Embodiment 1:

[0032] like Figures 1 to 8 As shown, an assembled prefabricated wall panel installation structure comprises a plurality of prefabricated wall panels 1 which are spliced ​​in sequence, the side walls of the prefabricated wall panels 1 being respectively provided with assembly protrusions 2 or assembly positioning holes 3, and the assembly protrusions 2 and assembly positioning holes 3 of adjacent prefabricated wall panels 1 are plugged together; the prefabricated wall panels 1 are provided with reserved grooves 4 at the side wall edges near the assembly protrusions 2 or the assembly positioning holes 3, and the reserved grooves 4 are provided with connecting ears 5, which are pre-buried in the prefabricated wall panels 1 and do not extend beyond the reserved grooves 4. When adjacent prefabricated wall panels 1 are assembled, the adjacent connecting ears 5 are connected by fastening components, and a closed filler 10 is provided in the reserved grooves 4.

[0033] The prefabricated wall panel installation structure improves the splicing structure of the prefabricated wall panel 1 to enable a more convenient and firm connection, thereby improving the connection and installation stability of the prefabricated wall panel, reducing on-site construction time and subsequent reinforcement construction. This wall panel structure can be used for indoor installation in buildings, and has higher stability and construction efficiency than traditional indoor brick walls.

[0034] The prefabricated wall panel 1 utilizes the cooperation of the assembly protrusion 2 and the assembly positioning hole 3 to enable adjacent prefabricated wall panels to be accurately docked. This positioning does not have a high connection strength. In order to further improve the connection strength and stability between adjacent prefabricated wall panels, the connecting ear piece 5 is provided on the edge of the side wall. When the adjacent prefabricated wall panels are docked, the connecting ear pieces 5 will also correspond one by one. Then, by utilizing the connection of the fastening component, the adjacent prefabricated wall panels 1 can be better connected together. During the tightening process of the fastening component, the prefabricated wall panels 1 will also be brought closer to each other, making the connection between the two tighter.

[0035] The assembly protrusion 2 and the assembly positioning hole 3 can be respectively arranged on two side walls of a single prefabricated wall panel, or can be arranged on the same side wall, as long as they can be matched with adjacent prefabricated wall panels.

[0036] The setting of the reserved groove 4 can accommodate the connecting ear piece 5 and the fastening assembly, so as to prevent the connecting ear piece 5 from being exposed from the surface of the prefabricated wall panel, and prevent many protrusions from appearing on the surface of the prefabricated wall panel after splicing.

[0037] The setting of the closed filler 10 can block the reserved groove 4, which can not only cover the connecting ear pieces and the fastening components, but also make the surface of the prefabricated wall panels after splicing smooth, which is convenient for subsequent wall construction, such as puttying, wall painting, etc.

[0038] The assembly protrusion 2, the assembly positioning hole 3 and the connecting ear piece 5 are set during the production process of the prefabricated wall panel 1, and only simple assembly is required at the construction site, which reduces the construction workload on site. There is basically no need to mix concrete cast-in-place walls on site, and only some cement mortar is needed for connection or repair.

[0039] Furthermore, a positioning sleeve 7 is embedded in the prefabricated wall panel 1, and the internal space of the positioning sleeve 7 is the assembly positioning hole 3; a first connecting rib 8 is provided at the end of the positioning sleeve 7, and the first connecting rib 8 is connected to the steel bar system 6 in the prefabricated wall panel 1, and the inner end of the connecting ear piece 5 is connected to the positioning sleeve 7.

[0040] The assembly positioning hole is provided in this way so that the connecting ear piece 5 can be connected and fixed there; the connecting ear piece 5 can be an integrally formed structure provided on both sides of the positioning sleeve 7, or can be welded thereon, and is connected to the steel bar body 6 through the first connecting rib 8, so that the force of the positioning sleeve 7 and the connecting ear piece 5 can be transmitted to the steel bar system 6, so that the entire prefabricated wall panel shares the force and avoids excessive local force.

[0041] The positioning sleeve 7 may be a metal positioning sleeve, and in addition to being connected to the connecting ear pieces, some reinforcements may be provided on its periphery to enhance the bonding ability with concrete.

[0042] Furthermore, the assembly protrusion 2 and the prefabricated wall panel 1 are an integrally formed prefabricated structure, and a second connecting rib 9 connected to the steel reinforcement system 6 in the prefabricated wall panel 1 is provided in the assembly protrusion 2, and the inner end of the connecting ear piece 5 there is connected to the second connecting rib 9.

[0043] The assembly protrusion 2 is directly manufactured by a process of being integrally formed with the prefabricated wall panel 1, which is more convenient to produce; the second connecting rib 9 can be an extension of the steel bar system 6 here. The second connecting rib 9 can ensure the strength of the assembly protrusion 2, and at the same time, the connecting ear 5 at this location can also be connected to the second connecting rib 9.

[0044] Through these arrangements, the connecting ears at various locations can be brought closer to the edge while ensuring their own connection strength, so as to reduce the distance between each pair of connecting ears for a tight connection.

[0045] Furthermore, the number of the assembly positioning holes 3 or the assembly protrusions 2 on the same side is two, which are arranged vertically, and the number of the reserved grooves 4 is four or two, which are arranged diagonally.

[0046] Generally, adjacent prefabricated wall panels can be accurately connected by positioning at the upper and lower positions, and the reserved groove 4 can be adaptively adjusted according to the size of the wall panels to reduce costs. Fig. 9 As shown, the reserved grooves 4 can be provided at the upper and lower diagonals of the side wall, and the connecting lugs 5 can also be provided in the same manner. The connecting lugs 5 on the upper and lower sides can be connected to fix the adjacent prefabricated wall panels. For prefabricated wall panels with larger sizes, the connecting lugs are provided on both sides of each prefabricated protrusion or pre-positioned hole, so that a stronger connection structure can be formed.

[0047] Furthermore, the fastening assembly includes a spacer 11 disposed between a pair of connecting ears 5 , and a bolt 12 connecting the connecting ears 5 and the spacer 11 .

[0048] Since there is a gap between each pair of connecting lugs, the spacer 11 is provided to fill the gap, which is conducive to the locking of the connecting lug 5. Small parts such as gaskets can also be used to make the connection better.

[0049] In some embodiments, an adhesive layer is further provided between adjacent prefabricated wall panels 1. The adhesive layer may be cement mortar or an interface agent so as to better bond adjacent prefabricated wall panels.

[0050] Further, the sealing filler 10 is a rubber block, a mud block or a mortar applied on site. The rubber block and the mud block (such as sealing cement) can be used directly to fill the reserved groove. The mortar is prepared on site and can use the above-mentioned cement mortar.

[0051] Embodiment 2:

[0052] The difference between this embodiment and the first embodiment is that a side support auxiliary device is provided.

[0053] When the prefabricated wall panel is large, in order to ensure its verticality and safety during indoor installation, supports can be set on its side. Fig.10 As shown, the side support auxiliary bracket includes a right-angle support plate 13, on which a hinge seat 14 is provided, and the hinge seat 14 is connected to an oblique support rod 15. The upper end of the oblique support rod 15 is provided with a support plate, which can be abutted against the prefabricated wall panel, or the upper end of the oblique support rod 15 is temporarily connected to the connecting ear.

[0054] The right-angle support plate 13 can ensure the verticality of the prefabricated wall panel installation, and can also support the prefabricated wall panel 1. The oblique support rod 15 can further support the upper part of the prefabricated wall panel to prevent it from overturning. After the prefabricated wall panel is pre-connected and the verticality is adjusted, the side support auxiliary bracket can be directly removed. The oblique support rod 15 can also be a telescopic rod.

[0055] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
