Description

Technical Field

[0001] This utility model belongs to the technical field of building structures, and in particular relates to prefabricated integrated thermal insulation composite walls. Background Technology

[0002] In current concrete construction projects, the common practice is to install floor slab insulation after the main building structure is completed. This method, for both cast-in-place and precast floor slabs, requires the main structure to be finished before installation, resulting in fewer overlapping construction steps. However, during the later installation of floor slab insulation, drilling holes in the slab can easily puncture pre-embedded conduits, preventing electrical wires, network cables, and signal cables from being run through them, or causing malfunctions. This necessitates addressing blockages or broken wires and rewiring the floor slab.

[0003] Construction quality control is quite difficult, and incidents of injuries caused by the first insulation layer falling off occur frequently. Therefore, this construction method has a low degree of process integration, rework and repairs are frequent, safety hazards are prominent, the first insulation layer falls off frequently, and the amount of construction solid waste generated is relatively increased, resulting in problems such as complicated construction procedures, high construction difficulty, increased construction costs, reduced construction efficiency, and extended construction period. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated integrated thermal insulation composite wall to solve the problem that the outer wall protective layer and the first insulation layer of the integrated thermal insulation composite wall are prone to falling off under long-term use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The prefabricated integrated thermal insulation composite wall consists of an outer sheet, a first insulation layer, and an inner sheet, which are stacked on top of each other from the outer layer to the inner layer.

[0007] The outer page plate is fixed with a steel cage in an array on the inner side. One end of the steel cage is pre-embedded and embedded in the outer page plate, and the other end extends and is embedded into the inner page plate.

[0008] The first insulation layer has pre-drilled holes at the positions corresponding to the reinforcing cage;

[0009] The inner page plate is embedded with horizontal and vertical reinforcing bars. The horizontal reinforcing bars are arranged in rows corresponding to the vertical direction, and the vertical reinforcing bars are arranged in rows corresponding to the horizontal direction. The intersection points of the horizontal and vertical reinforcing bars are fixed. The portion of the reinforcing cage extending into the inner page plate is fixed to the internal reinforcing bar skeleton of the inner page plate.

[0010] Furthermore, both the transverse and longitudinal reinforcing bars have extended portions corresponding to the inner edge of the plate. The extended portions of the transverse reinforcing bars are C-shaped, and the extended portions of the longitudinal reinforcing bars are strip-shaped. A second insulation layer is installed in the reserved hole.

[0011] Furthermore, the reinforcing cage is composed of multiple L-shaped reinforcing bars spliced ​​together. The short reinforcing bars of the L-shaped reinforcing bars are embedded in the outer plate, and the long reinforcing bars extend into the inner plate. Multiple sets of stirrups are installed on the long reinforcing bars of the L-shaped reinforcing bars.

[0012] This utility model has the following beneficial effects: The transverse and longitudinal reinforcing bars serve as the reinforcing skeleton of the inner sheet, with the intersections of the reinforcing bars welded or tied with binding wire. This insulated composite wall is an integrated structure; the corresponding outer sheet and inner sheet are connected by a multi-point reinforcing cage to form a unified structure. A first insulation layer is used as an insulation, fireproof, and flame-retardant material, increasing the wall's functionality. The insulation layer has pre-drilled holes to accommodate the reinforcing cage, which also serve as support points, improving the installation stability of the insulation layer and reducing the risk of the outer sheet and insulation layer falling off during long-term use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown: The prefabricated integrated thermal insulation composite wall consists of an outer sheet 1, a first insulation layer 2, and an inner sheet 3, which are stacked sequentially from the outer layer to the inner layer. The outer sheet serves as a protective and decorative layer, and is generally made of ceramic tiles or exposed concrete with a textured surface, offering better wear resistance, corrosion resistance, and durability. The inner sheet is a concrete structure. The first insulation layer is either rock wool board, a board structure made from molten basalt, which has good fire resistance, or foamed ceramic insulation board, which offers good thermal and sound insulation.

[0022] The outer page plate 1 is fixed with a steel cage 5 in an array on the inner side. One end of the steel cage 5 is pre-embedded and embedded in the outer page plate 1, and the other end extends and is embedded in the inner page plate 3.

[0023] The first insulation layer 2 has reserved holes 21 at the positions corresponding to the steel cage 5; the end projection of the steel cage is a square frame structure, and the corresponding reserved holes of the first insulation layer are square through holes.

[0024] The inner page plate 3 is embedded with transverse steel bars 31 and longitudinal steel bars 32. The transverse steel bars 31 are arranged in rows corresponding to the vertical direction, and the longitudinal steel bars 32 are arranged in rows corresponding to the horizontal direction. The intersection of the transverse steel bars 31 and the longitudinal steel bars 32 is fixed. The part of the steel cage 5 that extends to the inner page plate 3 is fixed with the steel skeleton inside the inner page plate 3.

[0025] Horizontal and longitudinal reinforcing bars form the reinforcing skeleton of the inner sheet panels, with intersections secured by welding or binding wire. This insulated composite wall is an integrated structure, with the outer and inner sheets connected by a multi-point reinforcing cage to form a unified structure. A first insulation layer serves as the insulation, fireproofing, and flame-retardant material, enhancing the wall's functionality. The insulation layer has pre-drilled holes to accommodate the reinforcing cage, which also act as support points, improving installation stability and reducing the risk of the outer sheets and insulation layer falling off during prolonged use.

[0026] Construction method: A reverse molding construction method is applied. First, the outer sheet is prepared, then the first insulation layer material is installed, and finally the inner sheet is poured. The inner and outer sheets are formed as a single unit.

[0027] like Figure 4As shown: Both the transverse reinforcing bars 31 and the longitudinal reinforcing bars 32 have extensions on the sides of the inner plate 3. The extension of the transverse reinforcing bars 31 is U-shaped, and the extension of the longitudinal reinforcing bars 32 is strip-shaped. These extended reinforcing bars are used for concrete pouring after the adjacent walls are assembled, serving as a reinforcing skeleton to increase the connection strength between adjacent walls. The extensions of the longitudinal reinforcing bars are also used for butt jointing using sleeve grouting technology. A second insulation layer 22 is installed in the pre-drilled hole 21. This second insulation layer is a filler layer, specifically polyurethane foam, which is sprayed and filled to fully contact all contact layers, providing not only fireproof and thermal insulation but also improving the contact strength of each surface. It has the best thermal conductivity among organic insulation materials, ranging from 0.022 to 0.027 W / m Kelvin. It is used to fill the gaps in the pre-drilled hole while ensuring the interface strength of each structure.

[0028] like Figure 5 As shown: The reinforcing cage 5 is composed of multiple L-shaped reinforcing bars 51 spliced ​​together. The short bars of the L-shaped reinforcing bars 51 are embedded in the outer plate 1, and the long bars extend into the inner plate 3. Multiple sets of stirrups 52 are installed on the long bars of the L-shaped reinforcing bars 51. The stirrups are square loop structures with multiple sets working together to increase the number of cross contact points between the reinforcing bars and improve connection stability. Specifically, there are four sets of stirrups: two sets at the bending points of the L-shaped reinforcing bars, one set in the middle, and one set at the free ends of the long bars.

[0029] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
