Description

TECHNICAL FIELD

[0001] The utility model relates to concrete wall technology field, concretely is a kind of foam concrete wall. BACKGROUND

[0002] With the growth of the demand for energy-saving and environment-friendly materials in the construction industry, the application of lightweight high-strength building materials is increasingly valued. Although traditional wall materials such as ordinary concrete and bricks have good compressive strength, they are heavy in weight, difficult to construct, and perform poorly in sound insulation. Therefore, it is particularly important to develop a new type of wall material that can not only reduce the overall weight of the building, but also has excellent sound insulation performance and sufficient impact resistance.

[0003] Foam concrete, as a lightweight building material, performs well in heat insulation, thermal insulation and sound insulation, but due to its physical properties, the impact resistance and structural stability of foam concrete wall are relatively weak, especially when facing large external forces, cracks or even breakage can easily occur. In addition, in traditional composite wall structures, the bonding strength between layers is often not high, which affects the integrity and durability of the wall. The existing methods to strengthen foam concrete walls mainly include increasing the thickness of the wall or adding reinforcing bars inside, however, these methods not only increase the weight of the wall, but also to some extent weaken the original lightweight advantage of foam concrete, and also fail to effectively solve the balance problem between wall sound insulation performance and structural strength. Therefore, a foam concrete wall is needed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a kind of foam concrete wall, with the advantages of lightweight high-strength, excellent sound insulation effect and enhanced impact resistance, solving the problems of poor impact resistance and structural stability of traditional foam concrete wall, low interlayer bonding strength.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a kind of foam concrete wall, comprising a foam concrete prefabricated wallboard, high-density concrete impact surface layer is arranged on the front and back sides of the foam concrete prefabricated wallboard, a porous cylinder skeleton is arranged in the foam concrete prefabricated wallboard, a through stress core column is arranged between the foam concrete prefabricated wallboard and the high-density concrete impact surface layer, the porous cylinder skeleton comprises a through cylinder and a connecting rib, and the through stress core column is installed in the through cylinder.

[0006] As a preferred foam concrete wall of the utility model, the through cylinder is arranged equidistantly in a rectangular shape, and the adjacent through cylinders are fixed by connecting ribs.

[0007] As a preferred embodiment of the foamed concrete wall of this utility model, the through-type stress core column includes a central shaft, a positioning plate, and an anti-detachment plate. The length of the central shaft is greater than the length of the through-tube, and the diameter of the positioning plate is equal to the inner diameter of the through-tube.

[0008] As a preferred embodiment of the foamed concrete wall of this utility model, a sealing membrane is provided on both the front and rear sides of the inner end of the through-tube, and the sealing membrane is made of polyvinyl chloride.

[0009] As a preferred embodiment of the foamed concrete wall of this utility model, the through-type stress core column is provided with conical piercing parts on both the front and rear sides.

[0010] As a preferred embodiment of the foamed concrete wall of this utility model, the porous cylindrical skeleton and the through-type stress core column are made of polytetrafluoroethylene.

[0011] As a preferred embodiment of the foamed concrete wall of this utility model, the thickness of the precast foamed concrete wall panel is 60-100mm, and the thickness of the high-density concrete impact-resistant surface layer is 20mm-50mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively disperses external impact loads through the equidistant arrangement of the porous cylindrical skeleton and the restraining effect of the connecting bars. While reducing the self-weight of the wall, it also suppresses the deformation tendency of the foamed concrete. The combination design of the through-type stress core column and the high-density impact-resistant surface layer forms a three-dimensional anchoring system, integrating the precast wall panel and the two side layers into a whole bearing structure. This solves the problems of easy peeling between layers and insufficient bending stiffness of traditional composite walls. This structure not only ensures lightweight characteristics, but also significantly improves the overall crack resistance and load-bearing capacity of the wall under complex loads.

[0014] 2. The continuous cavity network formed by the through-tube of this utility model extends the sound propagation loss through multiple sound wave reflection paths. Combined with the sealing effect of the polyvinyl chloride sealing film on the cavity, it avoids concrete seepage during the pouring process from damaging the cavity structure. This allows the wall to achieve the dual effect of physical sound insulation and sound absorption on the basis of lightweight construction. The piercing part design at the end of the through-core column breaks through the limitation of high positioning accuracy requirements of traditional embedded parts. The mechanical action of piercing the sealing film simplifies the on-site installation process. While ensuring the integrity of the cavity, it improves construction efficiency and solves the pain point of the incompatibility between the sound insulation structure of lightweight wall and rapid construction.

[0021] Please see Figures 1-5 A foamed concrete wall includes a precast foamed concrete wall panel 1, high-density concrete impact-resistant surface layer 2 on the front and rear sides of the precast foamed concrete wall panel 1, a porous cylindrical skeleton 3 inside the precast foamed concrete wall panel 1, and a through-type stress core column 4 between the precast foamed concrete wall panel 1 and the high-density concrete impact-resistant surface layer 2. The porous cylindrical skeleton 3 includes a through-tube 301 and connecting ribs 302, and the through-type stress core column 4 is installed inside the through-tube 301.

[0022] Furthermore, the through-tubes 301 are arranged in a rectangular shape at equal intervals, and adjacent through-tubes 301 are fixed together by connecting ribs 302.

[0023] The equidistant through-tubes 301 form a honeycomb structure, which improves the impact resistance of the wall and reduces the overall weight of the wall. The through-tubes 301 are connected by connecting bars 302, which can also restrain the deformation of the foamed concrete. Furthermore, several cavities are formed in the precast foamed concrete wall panel 1. Sound waves are reflected and scattered multiple times in the cavities, and the sound energy is converted into heat energy through air friction, thus improving the sound insulation effect.

[0024] Furthermore, the through-type stress core column 4 includes a central shaft 401, a positioning plate 402, and an anti-detachment plate 404. The length of the central shaft 401 is greater than the length of the through-tube 301, and the diameter of the positioning plate 402 is equal to the inner diameter of the through-tube 301.

[0025] The through-type stress core column 4 is installed inside the through-tube 301. Then, the high-density concrete impact-resistant surface layer 2 is poured. After the high-density concrete impact-resistant surface layer 2 solidifies, it firmly clamps and fixes the foam concrete precast wall panel 1 through the through-type stress core column 4, thereby improving the integrity of the wall, increasing the structural strength of the wall, and preventing the wall from cracking.

[0026] Furthermore, sealing membranes 303 are provided on both the front and rear sides of the inner end face of the through cylinder 301, and the sealing membranes 303 are made of polyvinyl chloride.

[0027] The through-tube 301 is sealed by the sealing membrane 303 to prevent cement from entering the through-tube 301 when pouring the high-density concrete impact-resistant surface layer 2, which would increase the weight of the wall and affect the sound insulation effect of the wall.

[0028] Furthermore, conical puncture portions 403 are provided on both the front and rear sides of the through-type stress core column 4.

[0029] The through-type stress core column 4 can be pierced through the sealing membrane 303 by the piercing part 403, thereby quickly installing the through-type stress core column 4 into the through-tube 301, which facilitates on-site construction and production.

[0030] Furthermore, the porous cylindrical skeleton 3 and the through-type stress core column 4 are made of polytetrafluoroethylene.

[0031] Polytetrafluoroethylene (PTFE) has good wear and corrosion resistance, strong impact resistance, and low density, which improves the overall structural strength of the wall and reduces its weight.

[0032] Furthermore, the thickness of the foamed concrete precast wall panel 1 is 60-100mm, and the thickness of the high-density concrete impact-resistant surface layer 2 is 20mm-50mm.

[0033] Composite walls ensure the wall's impact resistance, while the foamed concrete core ensures the wall's sound insulation, and also reduces the wall's weight while increasing the overall load-bearing capacity of the building.

[0034] In the preparation of this wall, firstly, a porous cylindrical frame 3 is placed in a pre-prepared rectangular mold. Then, foamed concrete is poured around the porous cylindrical frame 3 to form a precast wall panel with a thickness of 60-100mm. After solidification, the template is removed. Through-type stress core columns 4 are installed at the four corners of the precast wall panel. The through-type stress core columns 4 pierce the sealing membrane 303 through the piercing part 403 and are installed in the through-tube 301. The wall panel is erected in the area to be constructed, and a formwork is erected on its outside for final pouring. A high-density concrete impact-resistant surface layer 2 with a thickness of 20-50mm is poured, so that the anti-detachment plate 404 of the through-type stress core column 4 is embedded in the surface concrete. The stress core column forms a mechanical interlocking structure between the foamed concrete precast wall panel 1 and the surface layer. After the surface layer solidifies, the composite wall is completed.

[0035] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
