Description

Technical Field

[0001] The utility model relates to the field of autoclaved aerated concrete panels, in particular to an earthquake-resistant autoclaved aerated concrete panel. Background Art

[0002] Autoclaved aerated concrete board is a new type of green and environmentally friendly building material with light weight, porous material and different amount of anti-corrosion steel mesh added according to structural requirements. After high temperature, high pressure and steam curing, the autoclaved aerated concrete board with porous crystals is produced. Its density is lower than that of general cementitious materials, and it has excellent fire resistance, fire prevention, sound insulation, heat insulation, thermal insulation and other unparalleled properties.

[0003] The utility model discloses an autoclaved aerated concrete board (CN216076425U), including an autoclaved aerated concrete board body, a cavity is provided in the middle of the autoclaved aerated concrete board body, the inner wall of the cavity is rotatably connected with a rotating shaft in the vertical direction, a gear is fixedly sleeved on the surface of the rotating shaft, a rotating block is fixedly connected to the top surface of the rotating shaft, a first convex block is fixedly connected to the top surface of the rotating block, a first rotating groove is provided in the middle of the top surface of the autoclaved aerated concrete board body, a tooth plate is meshed on the surface of the gear, a limiting groove is provided inside the autoclaved aerated concrete board body, and the inner wall of the limiting groove is connected to the cavity. In use, the effect of temporarily supporting and connecting multiple autoclaved aerated concrete boards is achieved, and no additional supporting device is needed, which makes the installation process more convenient and improves the installation efficiency. At the same time, threading can be performed without punching holes in the board, which saves time and effort in the threading process and has good practicality. Since the autoclaved aerated concrete board uses a steel mesh as the middle metal layer, the adhesion between the steel mesh and the concrete is poor, and a long time of waiting for solidification is required during the production process, which affects the efficiency of its mass production. At the same time, since the surface of the autoclaved aerated concrete board is porous, after two autoclaved aerated concrete boards are assembled with each other, the surface of the autoclaved aerated concrete board needs to be polished before assembly to reduce the gap between the two autoclaved aerated concrete boards, which brings certain troubles to users.

[0004] To this end, we proposed an earthquake-resistant autoclaved aerated concrete slab. Utility Model Content

[0005] The utility model aims to provide a seismic-resistant autoclaved aerated concrete board to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the earthquake-resistant autoclaved aerated concrete panel comprises: an autoclaved aerated concrete layer, a corrugated metal plate and a second concrete plate, a break-resistant corrugated metal plate is arranged in the middle of the autoclaved aerated concrete layer, and a plurality of partitions are punched on both sides of the surface of the corrugated metal plate, the autoclaved aerated concrete layer is cast on both sides of the corrugated metal plate, and the autoclaved aerated concrete layer and the corrugated metal plate are subjected to high temperature, high pressure and steam curing, the outer wall of the autoclaved aerated concrete layer is cast with a concrete exoskeleton that reduces the assembly gap, and the surface of the concrete exoskeleton is a smooth layer.

[0007] Preferably, the corrugated metal plate is not provided with a partition in a transverse position along the waist tightening groove, and reinforcing ribs are bent at the connection between the corrugated metal plate and the partition.

[0008] Preferably, a waist tightening groove is opened in the middle of the concrete outer frame for facilitating assembly and fixation, and there are several waist tightening grooves.

[0009] Preferably, the autoclaved aerated concrete layer, the corrugated metal sheet, the side grooves, the concrete outer skeleton, and the waist tightening grooves constitute the first concrete slab and the second concrete slab.

[0010] Preferably, the second concrete slab is cast with protrusions along the concrete outer frame, and the protrusions correspond to the waist tightening grooves one by one.

[0011] Preferably, the second concrete slab is spliced ​​and fixed to the waist tightening groove on the first concrete slab through the protrusion, and several concrete slabs are installed one by one corresponding to each other.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the first concrete slab and the second concrete slab are both assembled by splicing a plurality of waist-tightening grooves and protrusions. The waist-tightening groove is an assembly groove, which satisfies the user's assembly and fixation of the autoclaved aerated concrete slab, and has a certain pre-fixing effect, providing convenience for the user's subsequent assembly and facilitating the user's use.

[0013] The utility model provides an earthquake-resistant autoclaved aerated concrete board. The entire corrugated metal board serves as a metal middle layer of the autoclaved aerated concrete board, which has good lateral support and anti-deformation effects. Meanwhile, a plurality of partitions are stamped on the surface of the corrugated metal board, which can improve the adhesion between the concrete and the metal middle layer when the concrete is poured.

[0014] When two sets of autoclaved aerated concrete layers, corrugated metal plates, side grooves, concrete exoskeletons, and waist tightening grooves form the first concrete slab and the second concrete slab, the first concrete slab and the second concrete slab are assembled with each other. Due to the design of the exoskeleton, the gap size at the connection between the first concrete slab and the second concrete slab is small, which provides convenience for the subsequent application of whitewash and concrete layers. At the same time, the side grooves are distributed along the front ends of the first concrete slab and the second concrete slab, which can improve the adhesion ability of the subsequent application of whitewash and concrete layers, and are convenient for users to use. At the same time, the autoclaved aerated concrete slab has the characteristics of light weight, good thermal insulation performance, high strength, good seismic performance, good processing performance, certain high temperature resistance, good sound insulation performance, conducive to mechanized construction and strong adaptability, which meets the requirements of the effective use of the autoclaved aerated concrete slab as a building material.

[0022] Embodiment 2

[0023] On the basis of Example 1, the corrugated metal plate 2 is not provided with partitions 22 in the transverse position along the waist-tightening groove 5, and reinforcing ribs 21 are bent at the connection between the corrugated metal plate 2 and the partitions 22. The entire corrugated metal plate 2 serves as the metal intermediate layer of the autoclaved aerated concrete board, which plays a good transverse support and anti-deformation effect. At the same time, a number of partitions 22 are stamped on the surface of the corrugated metal plate 2. The partitions 22 can improve the adhesion between the concrete and the metal intermediate layer during concrete pouring. The corrugated metal plate 2 is not provided with partitions 22 in the transverse position along the waist-tightening groove 5. When the autoclaved aerated concrete board is transversely connected, the waist-tightening groove 5 can be penetrated by a drilling device.

When two sets of autoclaved aerated concrete layers 1, the corrugated metal plate 2, the side groove 3, the concrete exoskeleton 4, and the waist tightening groove 5 constitute the first concrete slab and the second concrete slab 6, the first concrete slab and the second concrete slab 6 are assembled with each other.
