Description

Technical Field

[0001] This invention relates to the field of prefabricated building materials technology, and in particular to a self-insulating wall panel. Background Technology

[0002] Self-insulating wall panels are a new type of prefabricated building material. They consist of three layers: the outer protective layers on both sides are reinforced layers formed by foaming polystyrene particles and cement, with a steel mesh embedded in the reinforced layers to enhance the strength of the wall panels; and the inner core layer is a polystyrene particle board with good thermal insulation properties. Self-insulating wall panels are generally prefabricated by casting.

[0003] Before pouring the self-insulating wall panel, polystyrene particle boards of suitable shape and size are cut using cutting equipment. Then, two steel meshes are placed on both sides of the polystyrene particle board, and connecting steel bars are threaded through the polystyrene particle board. The two ends of the connecting steel bars and the two steel meshes are fixedly connected by welding or hooking. The two steel meshes are supported on both sides of the polystyrene particle board by the connecting steel bars. Then, the polystyrene particle board with the steel mesh is placed in a mold, and polystyrene particles and cement are injected into the mold to foam it. After solidification, the self-insulating wall panel is formed.

[0004] The invention application with publication number CN107724592A discloses a load-bearing aerated block prefabricated wall panel and floor slab. The wall panel is a panel prefabricated before existing masonry construction. The wall panel is composed of inner and outer concrete panels and an aerated block core layer. The outer concrete panel has an outer steel mesh, and the inner concrete panel has an inner steel mesh. The inner and outer steel meshes are welded or hooked together with connecting steel bars, which pass through the aerated block core layer.

[0005] Among the methods of fixing steel mesh, hooking requires bending tools and the fixing process is relatively laborious. Welding is a more labor-saving method for fixing steel mesh, but it is easy to generate sparks during welding. These sparks can easily burn the polystyrene particle board and affect the quality of the self-insulating wall panel after it is formed. Summary of the Invention

[0047] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0048] like Figure 1-11 As shown, a self-insulating wall panel of the present invention includes a foam board 1, a steel mesh 2, connecting steel bars 3, angle steel 4, and a concrete block 5.

[0049] In this system, a steel mesh 2 is installed on each side of the foam board 1, and a connecting steel bar 3 is placed between the two steel meshes 2 and passes through the foam board 1. The two steel meshes 2 are connected by the connecting steel bar 3. Angle steel 4 is installed at each end of the connecting steel bar 3, and the two ends of the connecting steel bar 3 are snapped into the inner side of the corresponding angle steel 4. Both ends of the angle steel 4 are provided with a locking slot 401, which is snapped into the steel mesh 2. A concrete block 5 is installed on each side of the foam board 1. The two steel meshes 2 are poured into the two concrete blocks 5 in a one-to-one correspondence.

[0050] In the above structure, the foam board 1 is a prefabricated polystyrene particle board. The reinforcing mesh 2 and the connecting reinforcing bars 3 are fixed by the angle steel 4, which realizes the welding-free assembly of the reinforcing mesh 2 and the connecting reinforcing bars 3. There are no welding sparks in the process, which is beneficial to the protection of the foam board 1, ensures the quality of the product after molding, and does not require bending operations, making the operation more labor-saving.

[0051] The reinforcing mesh 2 is a precast reinforcing mesh, including several first reinforcing bars 21 and several second reinforcing bars 22. The several first reinforcing bars 21 and several second reinforcing bars 22 are crisscrossed and fixed into a rectangular grid by welding. When the reinforcing mesh 2 and the foam board 1 are assembled, a reinforcing mesh 2 is set on each side of the foam board 1, and a connecting reinforcing bar 3 is set at the intersection of the corresponding first reinforcing bars 21 and second reinforcing bars 22. The connecting reinforcing bars 3 pass through the foam board 1. An angle steel 4 is set at both ends of each connecting reinforcing bar 3. Then, the first reinforcing bar 21 and the angle steel 4 are snapped together at one end of the clamp 401, and the second reinforcing bar 22 and the angle steel 4 are snapped together at the other end of the clamp 401, so as to realize the snap-fit ​​fixation of the angle steel 4 and the reinforcing mesh 2. Then, the connecting reinforcing bar 3 passes through the inside of the corresponding angle steel 4 and is snapped between the corresponding first reinforcing bars 21 and second reinforcing bars 22, so as to realize the snap-fit ​​fixation of the connecting reinforcing bar 3 and the angle steel 4.

[0052] To improve the clamping and fixing effect of angle steel 4 and reinforcing mesh 2, angle steel 4 is made of spring steel as an equilateral angle steel with a side width of 30-40mm, a side thickness of 3-4mm, and a length of 30-40mm. One end of angle steel 4 is parallel to the first reinforcing bar 21, and the other end is parallel to the second reinforcing bar 22. A clamping opening 401 on one end of angle steel 4 is provided through the axial direction of the first reinforcing bar 21, and a clamping opening 401 on the other end is provided through the axial direction of the second reinforcing bar 22. The clamping opening 401 is a U-shaped opening, and the opening width of the U-shaped opening is less than or equal to the outer diameter of the first reinforcing bar 21. The outer diameters of the first reinforcing bar 21, the second reinforcing bar 22, and the connecting reinforcing bar 3 are the same. This arrangement facilitates the clamping of angle steel 4 and reinforcing mesh 2.

[0053] Furthermore, the opening end of the bayonet 401 is flared, which makes it easy to insert the first reinforcing bar 21 and the second reinforcing bar 22 into the bayonet 401, thus facilitating installation.

[0054] To improve the clamping and fixing effect of the connecting steel bar 3 and the angle steel 4, a square-shaped positioning channel 301 is formed between the angle steel 4 and the corresponding first steel bar 21 and second steel bar 22. The connecting steel bar 3 passes through the positioning channel 301, and the width of the positioning channel 301 is less than or equal to the outer diameter of the connecting steel bar 3. This setting is conducive to the clamping of the connecting steel bar 3 and the angle steel 4, and the installation position of the connecting steel bar 3 can be positioned through the positioning channel 301, which facilitates the installation and positioning of the connecting steel bar 3, and facilitates the symmetrical installation of the two steel bar protective nets 2 on both sides of the foam board 1, thereby improving the quality of the product after molding.

[0055] As a preferred embodiment of the self-insulating wall panel, the concrete block 5 is formed by foaming polystyrene particles and cement. Dovetail grooves 501 are provided on one end of each of the two concrete blocks 5. Dovetail protrusions 101 are provided on both sides of the foam board 1 at the positions corresponding to the dovetail grooves 501. The dovetail protrusions 101 are inserted into the dovetail grooves 501. The dovetail protrusions 101 and the dovetail grooves 501 are used to improve the connection strength between the foam board 1 and the concrete block 5 and improve the tensile strength.

[0056] To facilitate the assembly of multiple self-insulating wall panels, positioning grooves 502 are provided on the two adjacent and right-angled ends of the concrete blocks 5, and positioning protrusions 503 are provided on the other two ends of the concrete blocks 5 opposite to the positioning grooves 502. During assembly, the positioning grooves 502 and positioning protrusions 503 are inserted to achieve the alignment of the two self-insulating wall panels, which is quite convenient.

[0057] In addition, to further facilitate the installation of the connecting steel bar 3, through holes for the connecting steel bar 3 are pre-drilled on the foam board 1 for inserting the connecting steel bar 3.

[0058] The manufacturing method of a self-insulating wall panel according to the present invention is as follows:

[0059] First, create a rectangular groove with wheels at the bottom for pouring the self-insulating wall panels. Then, separately... Figure 10 Foam board 1 and shown Figure 4 As shown in Figure 5, after the steel mesh 2 is made, it is placed on one side of the foam board 1. Several angle steels 4 are snapped onto the steel mesh 2 to form positioning channels 301, as shown in Figure 5. Several connecting steel bars 3 are prepared and inserted into the positioning channels 301 at different positions. Then, pressure is applied to all the connecting steel bars 3 and they penetrate the foam board 1. Another steel mesh 2 is prepared and several angle steels 4 are snapped onto it to form positioning channels 301. The connecting steel bars 3 are inserted into the corresponding positioning channels 301 in sequence. After insertion, the two steel meshes 2 are mirror-symmetrical on both sides of the foam board 1. At this time, the assembly of the skeleton is completed.

[0060] The assembled frame is then placed into a rectangular groove, and polystyrene particles and foamed cement are filled into the rectangular groove. The rectangular groove is then pushed into a curing kiln for curing, and after solidification, a self-insulating wall panel is formed.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
