Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and in particular relates to a prefabricated thermal insulation wall panel using staggered splicing and a construction method thereof. Background Art

[0002] With the acceleration of building industrialization, prefabricated buildings are becoming the mainstream development direction of the construction industry due to their advantages such as efficient construction, stable quality, energy saving and environmental protection. In applications in extremely cold areas, prefabricated insulation wall panels are key components. Their insulation layer is composed of multiple prefabricated panels. The connection technology directly affects the performance of the building. Currently, the commonly used methods are divided into two categories: one is to use adhesives to directly bond the insulation layer to the wall; the other is to physically fix it through mechanical components such as bolts and anchors, and use mechanical bite force to achieve rigid connection. The two processes have their own applicable scenarios in extremely cold areas, providing reliable technical support for the insulation system of prefabricated buildings.

[0003] However, traditional connection technologies have exposed significant defects in practical applications: the bonding method has low positioning accuracy of insulation panels, complex construction processes and reliance on highly skilled workers, making subsequent maintenance and disassembly difficult, which restricts the efficiency of industrialized construction; the mechanical fixing method is prone to corrosion and aging of bolts, which can easily lead to a decrease in the structural strength of wall panels, and is prone to thermal bridge effects, resulting in a decrease in insulation performance, making it difficult to meet the long-term performance requirements of enclosure systems in cold regions. Summary of the Invention

[0004] In view of this, the present invention aims to propose an assembled thermal insulation wall panel with staggered splicing and a construction method thereof, so as to solve the problems of large positioning deviation and difficulty in disassembly and modification in the bonding method, and to avoid the risk of mechanical performance degradation caused by aging of bolts in the mechanical fixing method and the problem of easy occurrence of thermal bridge effect.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A prefabricated thermal insulation wall panel using staggered splicing includes an autoclaved aerated concrete thermal insulation board, an insulation layer embedded part, a wall panel embedded part, and a concrete wall panel. The autoclaved aerated concrete thermal insulation board is provided in a plurality of pieces, and the plurality of autoclaved aerated concrete thermal insulation boards are connected by staggered splicing. The plurality of autoclaved aerated concrete thermal insulation boards are each embedded with an insulation layer embedded part, the insulation layer embedded part is connected to the wall panel embedded part, and the wall panel embedded part is installed in the concrete wall panel.

[0006] Furthermore, the autoclaved aerated concrete insulation board and the concrete wallboard are connected by an adhesive, and the joints between adjacent autoclaved aerated concrete insulation boards are filled with foamed glue.

[0007] Furthermore, both sides of the autoclaved aerated concrete insulation board are provided with half-thickness splicing tenons, and the other two sides are provided with half-thickness splicing grooves. The half-thickness splicing tenons are cooperated and connected with the half-thickness splicing grooves of the adjacent autoclaved aerated concrete insulation board. An anchoring protrusion is installed at the center of the autoclaved aerated concrete insulation board, and the insulation layer embedded parts are installed in the anchoring protrusion.

[0008] Furthermore, the length of the thermal insulation layer embedded part is greater than the length of the anchoring protrusion, a through screw hole is provided in the center, and an embedded protrusion is provided on the outside.

[0009] Furthermore, the wall panel embedded part includes an embedded plate, and a central circular hole is provided in the center of the embedded plate.

[0010] Furthermore, a plurality of reserved circular holes are provided on the inner side of the concrete wall panel, the centers of the reserved circular holes correspond to the center of the central circular hole, and a plurality of reserved grooves are provided on the outer side of the concrete wall panel, the sizes and positions of the reserved grooves correspond to the embedded protrusions.

[0011] Furthermore, the insulation layer embedded parts are connected to the wall panel embedded parts by bolts.

[0012] Furthermore, the materials of the thermal insulation layer embedded parts, the wall panel embedded parts and the bolts are all made of glass fiber reinforced plastic.

[0013] A construction method for assembled thermal insulation wall panels using staggered splicing, comprising the following steps: Step 1: First, use glass fiber reinforced plastic to process wall panel embedded parts, insulation layer embedded parts, and several bolts through molds in the factory, and then cast the autoclaved aerated concrete insulation board with built-in insulation layer embedded parts. The insulation layer embedded parts extend from the center of the anchoring block into the autoclaved aerated concrete insulation board.

[0014] Step 2: At the construction site, according to the specific construction plan, the wall panel embedded parts are tied to the designated positions by positioning and laying out the lines. Concrete is poured on site to obtain a concrete wall panel with the embedded wall panel parts. During pouring, a circular hole for a commonly used hexagonal wrench is reserved on the inner side of the concrete wall panel at the wall panel embedded parts, and a groove corresponding to the size of the anchoring protrusion is reserved on the outer side. Step 3. After the concrete wall panels are cured and solidified, the insulation layer is installed. To prevent the bolts from bearing excessive force during construction, the autoclaved aerated concrete insulation panels are installed from the bottom of the concrete wall panels to the top. First, clean the outer base of the concrete wall panels and evenly apply ACC special adhesive. Then, embed the anchoring protrusions of the autoclaved aerated concrete insulation panels into the outer grooves of the concrete wall panels. Then, pass the bolts through the inner circular holes of the concrete wall panels and the center circular holes of the wall panel embedded parts and screw them into the embedded parts of the insulation layer. Then, splice the next autoclaved aerated concrete insulation panel through the half-thick splicing protrusions and half-thick splicing grooves around the panels. Repeat the operation until all the autoclaved aerated concrete insulation panels are installed.

[0015] Step 4: Use foam glue to fill the joint gaps between the autoclaved aerated concrete insulation panels and the circular holes inside the concrete wall panels. After complete curing, a reliable anchoring connection between the concrete wall panels and the insulation layer is achieved.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The autoclaved aerated concrete insulation layer of the present invention is assembled by splicing prefabricated insulation boards, and is connected by aligning a number of grooves and protrusions, which is convenient for maintenance and replacement. At the same time, the splicing seams are no longer through, which has a lower risk of leakage than ordinary splicing seams, a lower degree of degradation in integrity, and better thermal insulation performance. It also avoids obvious splicing marks on the insulation boards after splicing and the problem of stress concentration.

[0017] 2. The connection method between the insulation layer and the wall panel of the present invention adopts a connection method that combines anchor connection and adhesive connection. This connection method has strong strength and is simple to construct, solving the problem of low connection strength of traditional insulation materials.

[0018] 3. The insulation layer embedded parts, wall panel embedded parts, screws and other anchoring devices of the present invention are all made of GFRP material, which is glass fiber reinforced plastic. The use of this material can effectively improve the durability of the components, increase the service life, and avoid the occurrence of thermal bridge effect. BRIEF DESCRIPTION OF THE DRAWINGS
