Description

Technical Field

[0001] This utility model relates to the field of block wall technology, and in particular to an energy-saving autoclaved aerated concrete block wall structure. Background Technology

[0002] Energy-saving autoclaved aerated concrete (AAC) block walls are lightweight porous wall materials made from cement, lime, sand (or fly ash, slag, and other silicon-containing materials) as the main raw materials, with the addition of a foaming agent (such as aluminum powder) and a high-pressure autoclaving process. Using these blocks to build walls is energy-saving and environmentally friendly, while also ensuring high strength and lightweight.

[0003] Chinese patent CN220666670U discloses an autoclaved aerated concrete (AAC) block and wall. The AAC block has a simple structure, requiring only pouring grooves on the left and right sides and the middle, and elongated grooves on the top and bottom sides. The AAC blocks are low in manufacturing cost, easy to transport, and do not suffer from damage. When building the wall, the blocks can be directly stacked, and the surfaces of the blocks can fit tightly together. Then, mortar is injected into the pouring holes and grooves to fix the blocks together. A connecting frame is used to fix adjacent blocks on the left and right sides, thus forming a stable and solid wall structure.

[0004] However, the device still has shortcomings: in this wall structure, two adjacent blocks need to be connected by a "mountain"-shaped connecting frame. The blocks are separate from the connecting frame, and the connecting frame needs to be inserted separately when building the wall, which is time-consuming and laborious. In addition, because it is necessary to ensure that the mortar can flow in the pouring hole, a gap needs to be left between the connecting frame and the inner wall of the pouring hole. This makes the two adjacent blocks easy to be displaced by external impact before the mortar dries. At the same time, the wall structure lacks a protective mechanism, and its thermal insulation and sound insulation performance is poor. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an energy-saving autoclaved aerated concrete block wall structure.

[0006] The technical solution of this utility model is: an energy-saving autoclaved aerated concrete block wall structure, including a wall body, the wall body including concrete blocks, the two ends of the concrete blocks are respectively provided with slots and blocks, the blocks are adapted to the slots, the upper end face of the concrete blocks is provided with several male plugs, and the lower end face of the concrete blocks is provided with several plug holes corresponding to each male plug. Beams and slabs are located at the top of the wall structure and are connected to the top layer of concrete blocks. In addition, protective mechanisms are installed on both sides of the wall body to enable the wall to have sound insulation, heat insulation and other properties.

[0007] Preferably, a flow channel A for injecting adhesive is provided on both the upper and lower surfaces of the concrete block. The flow channel A includes a main flow channel and a branch flow channel, and each branch flow channel is connected to the main flow channel.

[0008] Preferably, a flow channel B is provided on the concrete block at the end near the male connector, and the upper and lower sets of flow channels A are connected through the flow channel B, and a plug is provided at the end of the main flow channel away from the flow channel B.

[0009] Preferably, the concrete block is provided with a flow guide hole that penetrates through it, the flow guide hole connects the upper and lower sets of flow guide channels A, and the concrete block is provided with a conical groove that communicates with the flow guide hole.

[0010] Preferably, the bottom surface of the beam or slab is provided with several locking holes, which are inserted and locked into the uppermost concrete block.

[0011] Preferably, the slot is a T-shaped slot and the block is a T-shaped block, and there are no fewer than two slots and blocks on each concrete block.

[0012] Preferably, the protective structure includes a connecting layer, an insulation layer, a wire mesh, a mortar layer, and a putty layer. The connecting layer is the innermost layer and is attached to the wall body. The insulation layer is attached to the side of the connecting layer away from the wall body. The wire mesh is connected to the side of the insulation layer away from the connecting layer, and several reinforcing ribs are provided on the wire mesh. The reinforcing ribs are connected to the wall body through the connecting layer. The mortar layer is connected to the side of the wire mesh away from the insulation layer. The mortar penetrates the mesh openings of the wire mesh and connects to the insulation layer. The putty layer is connected to the side of the mortar layer away from the wire mesh. A finishing layer is provided on the side of the putty layer away from the mortar layer.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: By setting slots and blocks at both ends of the blocks, it is easy to ensure that adjacent blocks do not shift horizontally when they are joined together. By setting male and female insertion holes on the upper and lower end faces of the blocks, it is easy to prevent the upper and lower layers of blocks from shifting when stacking, and it can also improve the impact resistance of the wall even before the adhesive between the blocks has dried. By setting a matching structure of guide channel A, guide channel B and guide hole on the blocks, rapid grouting connection between upper and lower layers of blocks and between adjacent blocks in the horizontal direction can be achieved by direct grouting. At the same time, this utility model also adds a protective mechanism composed of a connecting layer, insulation layer, wire mesh, mortar layer, putty layer and finishing layer, which can prevent the wall from being eroded by rainwater and give the wall good thermal insulation and sound insulation performance.

[0016] Example 1, as Figures 1-4 As shown, this utility model proposes an energy-saving autoclaved aerated concrete (AAC) block wall structure, including a wall body, beams 3, and a protective mechanism 4. The wall body includes concrete blocks 1, with slots 101 and blocks 102 respectively provided at both ends of the concrete blocks 1. The blocks 102 are adapted to the slots 101. The slots 101 are T-shaped slots, and the blocks 102 are T-shaped blocks. Each concrete block 1 has at least two slots 101 and blocks 102. The upper surface of the concrete blocks 1 is provided with several male plugs 2, and the lower surface of the concrete blocks 1 is provided with several holes corresponding to each male plug 2. Both the upper and lower surfaces of the concrete blocks 1 are provided with guide channels A103 for injecting adhesive. The guide channels A103 include a main channel and branch channels, and each branch channel is connected to the main channel. A flow channel B104 is provided on the concrete block 1 at the end near the male connector 2. The upper and lower sets of flow channels A103 are connected through the flow channel B104, and a plug 107 is provided at the end of the main flow channel away from the flow channel B104. The beam slab 3 is located at the top of the wall body. Several locking holes 31 are provided on the bottom surface of the beam slab 3. The locking holes 31 are engaged with the male connector 2 of the uppermost concrete block 1. The protective mechanism 4 is set on both sides of the wall body. The protective mechanism 4 includes a connecting layer 41, an insulation layer 42, a wire mesh 43, a mortar layer 44, and a putty layer 45. The connecting layer 41 is the innermost layer and is attached to the wall body. The insulation layer 42 is attached to the side of the connecting layer 41 away from the wall body. The wire mesh 43 is attached to the side of the insulation layer 42 away from the wall body. The wall is connected to the side away from the connecting layer 41, and several reinforcing ribs are provided on the mesh 43. The reinforcing ribs are connected to the wall body through the connecting layer 41. The mortar layer 44 is connected to the side of the mesh 43 away from the insulation layer 42. The mortar penetrates the mesh holes on the mesh 43 and connects to the insulation layer 42. The putty layer 45 is connected to the side of the mortar layer 44 away from the mesh 43. A finishing layer 46 is provided on the side of the putty layer 45 away from the mortar layer 44, so that the wall has sound insulation and heat insulation properties through the protective mechanism 4.

[0017] In this embodiment, adjacent concrete blocks 1 are placed alternately. Two adjacent concrete blocks 1 in the horizontal direction are engaged by slots 101 and blocks 102. Since the concrete blocks 1 are precast components with uniform molding structures, they are highly consistent in size and shape. After being engaged, the two adjacent concrete blocks 1 in the horizontal direction exhibit good straightness. Furthermore, the staggered stacking of the upper and lower concrete blocks 1 further utilizes the wall's own weight to improve the stability of each concrete block. With a level base, the upper and lower layers of concrete blocks 1 have high side alignment. When stacking the second layer of concrete blocks 1, adhesive (such as highly fluid mortar or glue) is poured along the upper guide channel A103 to lock the upper and lower layers of concrete blocks 1 together. When injecting adhesive into the concrete blocks 1 located at the edge of the wall body, the exposed end of the guide channel A103 needs to be sealed with a plug 107 to prevent the adhesive from flowing away. After the main wall structure is completed, the beams and slabs are installed. These beams and slabs can be precast or cast on-site by placing formwork around the top layer of concrete blocks 1. Precast beams and slabs require an adhesive to improve their connection strength with the main wall structure. A connecting layer 41, which is an adhesive, is then applied to the wall. The insulation layer 42 is then bonded to the wall structure via the connecting layer 41. The insulation layer 42 uses, but is not limited to, rock wool insulation boards made of high-density rock wool. Then, the mesh 43 is fixed to the exterior of the rock wool insulation board using nails. Next, a mortar layer 44 is applied. After the mortar layer 44 dries, putty is applied to level the surface. Finally, a finishing layer 46 is sprayed on. The finishing layer 46 uses, but is not limited to, latex paint. The finishing layer 46 improves the aesthetics of the exterior of the wall. The insulation layer 42 uses rock wool insulation board, which not only has good insulation performance, but also has a large number of interconnected pores formed by the interweaving of fine fibers. After sound waves enter, they are converted into heat energy through air friction and fiber vibration. It is particularly effective in absorbing mid-to-high frequency noise (such as human voices and mechanical sounds).

[0018] Example 2, as Figure 2 As shown, the present invention proposes an energy-saving autoclaved aerated concrete block wall structure. Compared with the first embodiment, the concrete block 1 has a centrally located guide hole 105 that penetrates through it. The guide hole 105 connects two sets of guide channels A103, and the concrete block 1 has a conical groove 106 that connects to the guide hole 105.

[0019] In this embodiment, it is difficult to quickly and evenly fill the adhesive between the flow channels using the flow channel B104 at the end. Therefore, adding a flow hole in the center of the block can accelerate the uniform diffusion of the adhesive.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
