Description

Technical Field

[0001] The utility model relates to the field of concrete slabs, in particular to an assembled autoclaved aerated concrete slab. Background Art

[0002] Autoclaved aerated concrete board is a new type of lightweight, porous, green and environmentally friendly building material with cement, lime, silica sand and other raw materials as the main raw materials, and different amounts of anti-corrosion treated steel mesh are added according to structural requirements. After high temperature, high pressure and steam curing, the reaction generates autoclaved aerated concrete board with porous crystals. The density is lower than that of ordinary cement materials, and it has excellent fire resistance, fire prevention, sound insulation, heat insulation, thermal insulation and other unparalleled properties.

[0003] In the existing technology, the steel bars inside concrete slabs are generally embedded inside the slabs. During assembly, most of them are simply assembled by aligning the concrete and fixed with cement. However, the internal steel bars are still in a segmented state, which can only improve the vertical support force. When subjected to lateral external forces, they only rely on the fixed connection between the cement, resulting in poor integrity of the slab and poor linkage between the steel bars of each slab. Based on this, we propose an assembled autoclaved aerated concrete slab. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0025] This embodiment proposes an assembled autoclaved aerated concrete board, such as Figures 1 to 5 As shown, it includes a concrete slab 1, each concrete slab 1 has a positioning protrusion 4 fixed on the top surface, and each concrete slab 1 has a positioning groove 5 on the bottom surface that cooperates with the positioning protrusion 4;

[0026] The concrete slab 1 includes reinforcing steel bars 11 and concrete fillers 13. Several reinforcing steel bars 11 are equidistantly embedded in the concrete filler 13. A joint slot 14 is provided at the bottom of each reinforcing steel bar 11 extending to the inner end of the positioning groove 5. A steel bar joint 16 is welded and fixed to the top of each reinforcing steel bar 11 extending to the inner end of the positioning protrusion 4. Each steel bar joint 16 is inserted into the joint slot 14. When the concrete slab 1 is assembled and spliced, the bottom surface of the lowest concrete slab 1 can be placed horizontally on the ground, and the side surface close to the end of the limiting groove 3 can be attached to the wall. When fixed, concrete is applied to the concrete slab 1 on both sides of the limiting groove 3 to facilitate the fixation of the concrete slab 1 to the wall. When the upper and lower concrete slabs 1 are spliced, the limiting groove 3 Cement is applied to the side surfaces of the concrete slabs 1 on both sides, the side of the limiting protrusion 2 away from the concrete slab 1, and the top surface of the concrete slab 1 outside the positioning protrusion 4, and the bottom ends of the reinforcing steel bars 11 inside the positioning grooves 5 and the top ends of the steel bar joints 16 are heated and preliminarily melted. Then, the positioning grooves 5 of the upper concrete slab 1 are aligned and put on the positioning protrusions 4, so that the bottom ends of each reinforcing steel bar 11 are inserted into the steel bar slots 15, and the steel bar joints 16 are inserted into the joint slots 14. In this way, the reinforcing steel bars 11 of the upper and lower concrete slabs 1 are welded and fixed, and adjacent concrete slabs 1 are fixed by cement welding to ensure that the reinforcing steel bars 11 in the concrete slab 1 can maintain integrity after assembly, so that the concrete slab 1 has stronger lateral pressure resistance.

[0027] When the two vertical concrete slabs 1 are aligned and assembled up and down, the positioning protrusions 4 are aligned and inserted into the positioning grooves 5. At the same time, a limiting protrusion 2 is fixed at one end of each concrete slab 1, and a limiting groove 3 is opened at the other end of each concrete slab 1 to cooperate with the limiting protrusion 2. Each limiting protrusion 2 is inserted into the limiting groove 3, so that the concrete slab 1 of a horizontally adjacent concrete slab 1 is inserted into the limiting protrusion 2 of the other concrete slab 1. Specifically, each limiting protrusion 2 and limiting groove 3 are set to a horizontally placed "convex" type, and the height of each limiting protrusion 2 and limiting groove 3 is less than the height of the concrete slab 1. After assembly, the concrete slab 1 forms a complete body to avoid the formation of cavities. At the same time, under the "convex" type matching design, the two adjacent concrete slabs 1 are limited in the horizontal direction.

[0028] In this embodiment, a number of steel bar slots 15 that cooperate with the bottom ends of the reinforcing steel bars 11 are equidistantly provided inside the positioning protrusion 4. During assembly, the reinforcing steel bars 11 extending from the positioning groove 5 are aligned and inserted into the steel bar slots 15, so that the reinforcing steel bars 11 inside the concrete slab 1 are aligned one by one, and the top surface of each reinforcing steel bar 11 is flush with the bottom surface of the steel bar slot 15. Each steel bar joint 16 is fixed to the top surface of the reinforcing steel bar 11 inside the steel bar slot 15. After the steel bar joint 16 is welded and fixed to the reinforcing steel bar 11 of the upper concrete slab 1 and the upper and lower reinforcing steel bars 11 are welded and fixed, the firmness of the connection between the upper and lower concrete slabs 1 can be further strengthened. At the same time, the two adjacent concrete slabs 1 are laterally reinforced by the limiting groove 3 and the limiting protrusion 2, thereby ensuring the firmness and sealing of the connection after the concrete slab 1 is assembled.

[0029] On the basis of the above scheme, the concrete slab 1 in this embodiment also includes a reinforcing iron mesh 12, a waterproof coating 17 and a connecting steel sleeve 18. The concrete fillers 13 on both sides of the reinforcing steel bars 11 are embedded with reinforcing iron mesh 12 to enhance the adhesion of the concrete fillers 13. The concrete fillers 13 on the outside of each reinforcing iron mesh 12 are embedded with fireproof partitions to enhance the thermal insulation performance of the concrete slab 1. The height of each reinforcing iron mesh 12 is less than the height of the concrete slab 1 to avoid the reinforcing iron mesh 12 from affecting the normal assembly of the concrete slab 1 after it emerges. The adjacent two reinforcing steel bars 11 are connected by The steel sleeves 18 are fixedly connected to strengthen the transverse connection between adjacent concrete slabs 1, thereby increasing the tensile strength of both ends of the concrete slab 1. The outer surface of the concrete filler 13 and the inner wall of the limiting groove 3 are wrapped and coated with a waterproof coating 17 to improve the waterproof performance of the concrete slab 1. The two ends of each connecting steel sleeve 18 are set to an arc shape that matches the reinforcing steel bar 11. Each connecting steel sleeve 18 is fixed to the reinforcing steel bar 11 by winding iron wire. Each adjacent group of connecting steel sleeves 18 are staggered up and down to avoid mutual influence between the connecting steel sleeves 18 and ensure the firmness of the connection between the connecting steel sleeves 18 and the reinforcing steel bar 11.
