Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a flame-retardant and heat-insulating prefabricated steel frame molded wall panel. Background Technology

[0002] Steel-framed molded wall panels are prefabricated panels composed of a steel frame and a molded insulation core. Due to their excellent structural strength and insulation performance, they are widely used in modern architecture. Currently, these wall panels are generally installed using a flat panel splicing method, with the joints between adjacent panels often being simple straight, continuous seams. However, this type of straight-through joint has inherent structural defects: firstly, it provides a direct and unobstructed channel for rainwater infiltration; secondly, under external wind pressure, rainwater can easily penetrate the wall along this straight path, leading to indoor leaks and severely affecting the building's functionality and durability. Existing technologies often rely on filling the joints with sealant to compensate, but sealant is prone to aging, and its long-term waterproofing effect is unreliable. Utility Model Content

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a flame-retardant and heat-insulating prefabricated steel frame molded wall panel.

[0004] The technical solution of this utility model is: a flame-retardant and heat-insulating prefabricated steel frame molded wall panel, including symmetrically distributed vertical keels, and evenly distributed horizontal keels installed between the symmetrically distributed vertical keels by bolts, with a panel placed between adjacent horizontal keels, and an embedded frame inside the panel.

[0005] Furthermore, it is particularly preferred that both the cross-section and vertical section of the plate are Z-shaped.

[0006] Furthermore, it is particularly preferred that a connecting shell 1 is slidably connected to the lower side of the front of the built-in frame, and a connecting shell 2 is slidably connected to the lower part of the connecting shell 1. A spring 1 is connected between the connecting shell 1 and the adjacent connecting shell 2.

[0007] Furthermore, it is particularly preferred that both connecting shell one and connecting shell two are embedded with fixing posts, and plugs are slidably connected to both ends of the fixing posts, with a spring two connecting the two plugs in the same fixing post.

[0008] Furthermore, it is particularly preferred that symmetrically distributed limiting grooves are provided on both the upper and lower sides of the front of the built-in frame, and the limiting grooves cooperate with the adjacent plugs to restrict the movement of the adjacent connecting shell one or connecting shell two.

[0009] Furthermore, it is particularly preferred that the upper and lower ends of the front of the built-in frame are provided with symmetrically distributed guide grooves, which are used to guide adjacent plugs into adjacent built-in frames.

[0010] Furthermore, it is particularly preferred that the connecting shell one is provided with symmetrically distributed guide grooves on the side near the adjacent connecting shell two, the guide grooves being used to guide the adjacent fixed columns.

[0011] Furthermore, it is particularly preferred that the horizontal keel is composed of C-shaped steel and cover plate, and that the C-shaped steel and cover plate are interlocked and connected together by bolts.

[0012] The beneficial effects of this utility model are: This invention transforms the joint between two adjacent panels into a Z-shape, which not only effectively cuts off the straight flow path of rainwater under capillary action and gravity, but also blocks rainwater multiple times as it penetrates this tortuous channel, changing its direction and significantly weakening its kinetic energy. This makes it difficult for rainwater to penetrate into the interior, while also creating a neat and refined appearance and preventing panel bulging, deformation, or joint tearing caused by stress accumulation.

[0013] This invention simplifies the installation steps of wall panels, achieving integrated alignment and connection, thereby quickly connecting the upper and lower panels together. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] A flame-retardant and heat-insulating prefabricated steel-framed molded wall panel, such as Figure 1 and Figure 2 As shown, it includes two vertical keels 1, and horizontal keels 2 evenly distributed between the two vertical keels 1 by bolts. A board 3 is placed between two adjacent horizontal keels 2. The board 3 is made of EPS particles, so it has excellent thermal insulation performance as well as good moisture-proof and water-resistant performance. At the same time, the board 3 is treated with flame retardant. The cross section and vertical section of the board 3 are both Z-shaped, which changes the connection seam between two adjacent boards into a Z-shape, making the appearance neat and exquisite, and avoiding wall panel bulging, deformation or joint tearing caused by stress accumulation. The board 3 has an embedded internal skeleton 4, which is welded from hollow rectangular tubes.

[0023] like Figures 2-5 As shown, each of the lower front sides of the built-in frame 4 is slidably connected to a connecting shell 1 5. The number of connecting shells 1 5 corresponds to the number of vertical hollow tubes on the lower front side of the built-in frame 4. The lower part of the connecting shell 1 5 is slidably connected to a connecting shell 2 6. A spring 1 7 connects the connecting shell 1 5 and the adjacent connecting shell 2 6.

[0024] like Figures 2-5 As shown, both connecting shell 1 5 and connecting shell 2 6 have two fixed posts 8 embedded in them. The lower side of connecting shell 1 5 is provided with four guide grooves 13, which are used to guide adjacent fixed posts 8. Both ends of the fixed posts 8 are slidably connected to plugs 9. The upper and lower sides of the front of the built-in frame 4 are provided with four limiting grooves 11, which cooperate with adjacent plugs 9 to restrict the movement of adjacent connecting shell 1 5 or connecting shell 2 6. The upper and lower ends of the front of the built-in frame 4 are provided with four guide grooves 12, which are used to guide adjacent plugs 9 into adjacent built-in frames 4. The two plugs 9 in the same fixed post 8 are connected by a spring 2 10.

[0025] like Figure 6 As shown, the horizontal keel 2 is composed of C-shaped steel 201 and cover plate 202, and the C-shaped steel 201 and cover plate 202 are interlocked and connected together by bolts. Before installing the wall panel, the workers can disassemble the C-shaped steel 201 and cover plate 202 and run wires inside the C-shaped steel 201.

[0026] During the installation of the wall panels, the workers first installed the horizontal keel 2 between the two vertical keels 1 using bolts, and then followed... Figure 1 The method involves placing the board 3 on the horizontal keel 2. During this process, the joint between two adjacent boards 3 is sealed with sealant to prevent moisture from entering the joint between the two boards 3. At the same time, the joint between two adjacent boards 3 is Z-shaped. This not only effectively cuts off the straight flow path of rainwater under capillary action and gravity, but also blocks rainwater multiple times when it passes through this tortuous channel, changes its direction and greatly weakens its kinetic energy, making it difficult for rainwater to penetrate to the indoor side. This also makes the appearance neat and exquisite, and avoids the board 3 from bulging, deforming or tearing of the joints due to stress accumulation.

[0027] After the first layer of panels 3 is placed, the above process is repeated to install the new horizontal keel 2. Then, the worker inserts two connecting shells 5 into the lower front part of the inner frame 4. During this process, the plug 9 inside the connecting shell 5 contacts the adjacent guide groove 12 and is guided into the inner frame 4. At this time, the spring 10 is compressed until the plug 9 aligns with the adjacent limiting groove 11. Under the action of the spring 10, the two plugs 9 are inserted into the adjacent limiting grooves 11 respectively. Then, the worker repeats the above steps to place the panels 3 on the horizontal keel 2. At this time, under the squeezing action of the two adjacent panels 3, the connecting shell 6 moves towards the adjacent connecting... The connector moves within the shell 5 and compresses the adjacent spring 7 until the plug 9 on the connecting shell 6 enters the adjacent guide groove 13 through the adjacent guide groove 12, and the lower side of the connecting shell 6 is flush with the lower side of the adjacent connecting shell 5. Then the upper and lower sides of the two plates 3 come into contact with each other. Then the workers can move the plates 3 left and right until the two connecting shells 6 are aligned with the built-in frame 4 in the lower plate 3. Under the action of the spring 7, the connecting shells 6 enter the built-in frame 4 in the lower plate 3. This simplifies the steps of installing the wall panel and realizes the integrated operation of alignment and connection, so as to quickly connect the upper and lower plates 3 together.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
