Technical Field

[0001] The utility model relates to the field of aerated concrete blocks, in particular to a heat-insulating and crack-resistant aerated concrete block. Background Art

[0002] Aerated concrete blocks have good thermal insulation properties, environmental advantages, and light weight, and are widely used in high-rise frame structure buildings.

[0003] The strength of ordinary aerated concrete blocks is not high. In order to improve the thermal insulation effect, some aerated concrete blocks are designed with hollow grooves, which further reduces the structural strength. Although a single aerated concrete block has a certain earthquake resistance effect, the overall earthquake resistance after the wall is built is poor. It is easy to crack during vibration or impact, which affects the safety of use and limits the use and development of aerated concrete blocks. Improvements are needed. Utility Model Content

[0014] Figure 2 yes Figure 1 Top view of the . DETAILED DESCRIPTION

[0015] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The heat-insulating and crack-proof aerated concrete block shown comprises: a block base 1, a heat-insulating board 2, a first grouting sleeve 3 and a second grouting sleeve 4. The heat-insulating board 2 is spaced along the width direction of the block base 1 and vertically arranged in the block base 1. In this embodiment, the heat-insulating board 2 is made of a foamed resin board, which has a light weight and a good heat-insulating effect. Figure 2 As shown, two heat-insulating panels 2 are used, respectively close to the front and back of the block base 1, to perform double-sided heat insulation on the block base 1, and after the wall is built, the two-way heat insulation effect inside and outside the building is improved.

[0017] A protrusion 11 is horizontally arranged at the front end of the block base 1, and a groove 12 corresponding to the protrusion 11 is horizontally arranged at the rear end of the block base 1. The number of the protrusion is at least one. Through the cooperation between the protrusion 11 and the groove 12, the two adjacent aerated concrete blocks 1 on the left and right are coordinated during wall construction to reduce the problem of upper and lower misalignment.

[0018] like Figure 2 As shown, the first grouting sleeve 3 is vertically arranged in the protrusion 11 and is located in front of the thermal insulation board 2, and the second grouting sleeve 4 is vertically arranged at the rear end of the block base 1 and is located behind the thermal insulation board 2. During the wall construction process, after the protrusion of the rear block base is inserted into the groove of the front block base, the corresponding first grouting sleeve is concentric with the second grouting sleeve, which is convenient for grouting and fixing.

[0019] A connecting rib 5 penetrating the thermal insulation board 2 is arranged between the first grouting sleeve in front of the thermal insulation board 2 and the second grouting sleeve behind the thermal insulation board 2. The thermal insulation board 2 is fixed by the connecting rib 5, which is beneficial to the molding of the block matrix 1 in the mold and avoids the drift of the thermal insulation board 2.

[0020] like Figure 1 As shown, the second grouting sleeve 4 is located above and below the groove 12, and the first grouting sleeve 3 in front of the thermal insulation board 2 can be obliquely connected to the second grouting sleeve 4 above and below the rear groove 12 through two connecting ribs to improve the structural strength.

[0021] In this embodiment, the connecting reinforcement 5 is made of steel bars, the first grouting sleeve 3 and the second grouting sleeve 4 are respectively made of steel sleeves, and the two ends of the connecting reinforcement 5 are respectively welded and fixed to the corresponding first grouting sleeve 3 and the second grouting sleeve 4, so that the structure is stable and the tensile effect is good.

[0022] When two adjacent aerated concrete blocks are built, the first grouting sleeve 3 and the second grouting sleeve 4 are used to fix them after grouting, and the connecting bars are used for diagonal reinforcement, which improves the structural strength and earthquake resistance and effectively prevents cracking.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes.
