Technical Field

[0001] This utility model relates to the field of prefabricated wall panel technology, specifically to a prefabricated wall panel for sound and heat insulation in assembled buildings. Background Technology

[0002] Precast sound and heat insulation wall panels are industrialized prefabricated wall components that combine sound insulation and heat insulation functions. They are mainly used in building envelopes to improve the acoustic and thermal performance of buildings while meeting the high-efficiency construction requirements of prefabricated buildings. These prefabricated sound and heat insulation wall panels are prefabricated in a factory to form "functional integrated panels," which can be directly used as exterior / interior partition walls, significantly simplifying the on-site installation process.

[0003] To facilitate the assembly of wall panels, the wall panel structure is usually functionally optimized, such as the common tongue and groove tenon structure. The production and processing of this type of wall panel is complex, and the mold cost and wear increase, which in turn increases the production cost. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a prefabricated sound and heat insulation wall panel for prefabricated buildings, including a prefabricated wall panel body 1 and an assembly positioning component 2. The assembly positioning component 2 is installed at a set of corners of the prefabricated wall panel body 1. The assembly positioning component 2 is configured with a cross-shaped structure. The assembly positioning component 2 includes a first connecting edge 21 and a second connecting edge 22. A first stepped hole 23 is opened on the first connecting edge 21, and the first stepped hole 23 includes a first screw hole 25. A second stepped hole 24 is opened on the second connecting edge 22, and the second stepped hole 24 includes a second screw hole 26. The first connecting edge 21 is fixedly connected to the prefabricated wall panel body 1 by a first countersunk bolt 28, and the second connecting edge 22 is fixedly connected to the prefabricated wall panel body 1 by a second countersunk bolt 29.

[0026] The assembly positioning component 2 is an external structure, which does not require any changes to the structure of the precast wall panel body 1. The precast wall panel body 1 is still a flat joint wall panel structure. The structural design of the flat joint wall panel does not require complex tongue and groove or tenon and mortise joints, which greatly simplifies the production process. Ordinary steel molds can produce the precast wall panel body 1. The mold cost is low. It is only necessary to open corresponding screw holes on the side of the precast wall panel body 1.

[0027] The assembly positioning component 2 is installed at a set of corners of the precast wall panel body 1, and the two are fixedly connected by countersunk bolts. The assembly positioning component 2 forms the positioning base point during assembly. The assembly positioning component 2 includes four sets of positioning grooves, each set of positioning grooves corresponding to a set of corners of the precast wall panel body 1. When assembling multiple sets of precast wall panel bodies 1, such as... Figure 4 As shown, multiple precast wall panel bodies 1 can be quickly positioned by assembling positioning parts 2, which is convenient for on-site operation, and the gap between two adjacent precast wall panel bodies 1 is the same after positioning.

[0028] The precast wall panel body 1 and the assembly positioning component 2 are detachably connected, so that the assembly positioning component 2 can be replaced separately when it is damaged.

[0029] The first connecting edge 21 and the second connecting edge 22 are arranged perpendicularly to each other. The first connecting edge 21 is attached to a set of straight edges of the precast wall panel body 1, and the second connecting edge 22 is attached to another set of straight edges of the precast wall panel body 1.

[0030] The assembly positioning component 2 has a central hole 27 at its center, which forms a connection between the assembly positioning component 2 and the main structure. The precast wall panel body 1 can be bonded to the main structure with polymer adhesive mortar, and the assembly positioning component 2 and the main structure can be anchored together with bolts to achieve reinforcement.

[0031] Two sets of screw holes are provided on the main body 1 of the precast wall panel.

[0032] One set of screw holes is aligned with the first screw hole 25 of the first connecting edge 21, and the other set of screw holes is aligned with the second screw hole 26 of the second connecting edge 22, such as... Figure 1 As shown, when the assembly positioning component 2 is located at the corner of the precast wall panel body 1, the screw holes of the precast wall panel body 1 are aligned with the first screw hole 25 and the second screw hole 26 of the assembly positioning component 2 to form connection holes.

[0033] The first countersunk bolt 28 is screwed into the threaded hole of the precast wall panel body 1, and the head of the first countersunk bolt 28 is embedded in the first stepped hole 23. After the first countersunk bolt 28 is installed in place, its head will not protrude and will not affect the normal positioning during assembly.

[0034] The second countersunk bolt 29 is screwed into the threaded hole of the precast wall panel body 1, and the head of the second countersunk bolt 29 is embedded in the second stepped hole 24. After the second countersunk bolt 29 is installed in place, its head will not protrude and will not affect the normal positioning during assembly.

[0035] Among them, a gap is formed between two adjacent sets of prefabricated wall panels 1, and the gap is filled with sealant 3. The sealant 3 prevents water vapor penetration through a continuous and sealed film, which can inhibit the growth of mold in the gap and avoid problems such as mold and peeling of the wall. The sealant 3 reduces heat conduction by blocking air flow and filling the gap, which can also reduce noise.

[0036] The precast wall panel body 1 includes a decorative layer 11 and a structural functional layer 12. The decorative layer 11 is the outer layer and the structural functional layer 12 is the inner layer. The decorative layer 11 can resist external physical impacts, such as collisions and scratches, and protect the internal structural functional layer 12 from damage.

[0037] The structural functional layer 12 includes a sound-absorbing layer, a damping layer, and a thermal insulation layer. The sound-absorbing layer is a porous sound-absorbing material, the damping layer is a butyl rubber damping sheet or a viscoelastic adhesive, and the thermal insulation layer is composed of polyurethane or rigid polyurethane foam thermal insulation material to achieve sound insulation and heat insulation.

[0038] Working principle: During use, the assembly positioning component 2 is installed at a set of corners of the precast wall panel body 1, and the two are fixedly connected by countersunk bolts. The assembly positioning component 2 forms the positioning base point during assembly. The assembly positioning component 2 includes four sets of positioning grooves, each set of positioning grooves corresponding to a set of corners of the precast wall panel body 1. When assembling multiple sets of precast wall panel bodies 1, they can be bonded to the main structure through polymer adhesive mortar, such as... Figure 4 As shown, multiple sets of prefabricated wall panel bodies 1 are quickly positioned by assembling positioning parts 2, and the gap between two adjacent sets of prefabricated wall panel bodies 1 is the same after positioning. After the wall panels are assembled, sealant 3 is filled into the gap between the wall panels.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
