Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically to a prefabricated PC concrete slab with good thermal insulation effect. Background Technology

[0002] Concrete slabs are a common building material, typically used for constructing floor slabs, floors, roofs, and other building structures. They are made from a mixture of cement, sand, and gravel, and are produced through processes such as pouring, vibration, and curing. Precast concrete (PC) slabs are concrete components prefabricated in a factory, possessing excellent compressive strength and durability. To improve their thermal insulation performance, special designs and materials are often employed, including adding insulation materials such as polystyrene boards, extruded polystyrene (XPS), rock wool, and glass wool inside or at the bottom of the concrete slab to effectively reduce heat conduction. Furthermore, the robust structure of the PC slab itself ensures the fixation and thermal insulation effect of the insulation materials.

[0003] A search revealed that Chinese patent CN215716752U discloses a prefabricated fireproof, thermal insulation, and decorative exterior wall system. This patent describes a system consisting of prefabricated aerated concrete panels, B1-grade fireproof insulation panels, thermal insulation mortar, and decorative panels. The prefabricated aerated concrete panels with internal embedded parts provide wall strength. The decorative panels are rigid decorative panels. Polymer mortar is used to bond the prefabricated aerated concrete panels and the B1-grade fireproof insulation panels, as well as the thermal insulation mortar and the decorative panels. The bonding between the B1-grade fireproof insulation panels and the thermal insulation mortar is also present. This system reduces construction steps, improves construction efficiency, lowers labor costs, is easy to assemble on-site, and features a reasonable, simple, safe, reliable, versatile, and environmentally friendly technical solution.

[0004] The inability to quickly assemble the equipment in this solution will affect the progress of the entire project, delay project delivery, increase project risks, and lead to increased difficulty in quality control at the construction site, thus affecting the final construction quality. In order to solve this technical problem, this utility model proposes a prefabricated PC concrete board with good thermal insulation effect. Summary of the Invention

[0023] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A prefabricated PC (polycarbonate) concrete slab with good thermal insulation performance includes a wall 1, and a second wall 2 installed on the outer side of the first wall 1. The second wall 2 includes an anti-detachment layer 8, a thermal insulation mortar layer 9, a thermal insulation board layer 10, and an adhesive layer 11. The adhesive layer 11 is provided on the surface of the first wall 1, the thermal insulation board layer 10 is provided on the outer side of the adhesive layer 11, the thermal insulation mortar layer 9 is provided on the outer side of the thermal insulation board layer 10, and the anti-detachment layer 8 is provided on the outer side of the thermal insulation mortar layer 9. The second wall 2 adopts a structural design of anti-detachment layer 8, thermal insulation mortar layer 9, thermal insulation board layer 10, and adhesive layer 11. The structural design of the thermal insulation layer and the anti-detachment layer is also included. The design effectively improves the thermal insulation performance of the concrete slab, prevents heat loss, and maintains a stable indoor temperature. A fixing column 5 is fixedly connected to the outer wall of wall 1. The fixing column 5 has an internal permeation hole 6 and a connection hole 7 on its outer side. A grouting hole 3 is located at the top of wall 2. A limiting groove 4 is formed inside wall 2. Grouting holes 3 and 4 allow mortar to be injected into the grouting hole 3 to fix wall 1 and wall 2. The outer side of wall 1 is connected to wall 2 via the side wall fixing column 5, ensuring a secure connection between the two walls. The internal permeation hole 6 and the connection hole 7 of the column allow the fixing column 5 to be connected between wall 1 and wall 2, enhancing the tightness of the connection.

[0026] Example 2: The difference between this example and Example 1 is that the thermal insulation mortar layer 9 is made of polymer mortar. This material has good thermal insulation performance, which can effectively reduce heat loss and improve the thermal insulation effect of the concrete slab. The bonding layer 11 is made of block adhesive, and the anti-detachment layer 8 is made of block plastering mortar. The size of the fixing column 5 matches the size of the opening of the grouting hole 3. This ensures a tighter connection during grouting and enhances the connection between the support structure of wall 1 and wall 2. Grouting holes 2 12 are provided on one side of wall 1 and are arranged in a linear array. Grouting holes 2 12 are also provided on the top of wall 1 and are arranged in a linear array. This arrangement makes the grouting process more convenient and faster, and can quickly complete the construction of the concrete slab.

[0027] During operation, wall 1 and wall 2 are first fitted together. The fixing post 5 on wall 1 is then fixed to the grouting hole 3 on wall 2. Mortar is then poured into the limiting groove 4 and the permeation hole 6 through the grouting hole 3, allowing the equipment to quickly form. The limiting groove 4 has a hollow structure, allowing a large amount of mortar to enter the permeation hole 6, thus making the connection between wall 1 and wall 2 more stable. The anti-detachment layer 8 is located on the outside of wall 2 and its function is to prevent the insulation mortar layer 9 and insulation board layer 10 from falling off or being damaged during use, improving the stability and durability of the insulation layer. The insulation mortar layer 9 is one of the insulation layers in wall 2, located between the insulation board layer 10 and the anti-detachment layer 8. Its function is to improve the insulation performance of the concrete board, reduce heat conduction, and maintain a stable indoor temperature. The insulation board layer 10 is the main insulation layer in wall 2, and its function is to effectively insulate, reduce heat loss, and improve the building's insulation effect. The adhesive layer 11 is located on the surface of wall 1. Its function is to bond wall 1 and wall 2 tightly together, ensuring a firm connection between the two and preventing loosening or falling off during use.
