Description

Technical Field

[0001] The utility model relates to the technical field of aerated concrete blocks, and particularly relates to a post-insertion chain block for an aerated concrete block wall. Background Art

[0002] Cracks are likely to occur in the post-insertion of a large number of masonry, resulting in cracks at the bottom of the beam of the framed infill wall. There are many factors, and the most important one is caused by the shrinkage of blocks and mortar. The following problems will occur:

[0003] 1. The shrinkage of blocks will cause cracks, and the shrinkage rate of lightweight blocks is greater than that of clay bricks. During the natural shrinkage process, with the decrease of water content, the material will produce large dry shrinkage deformation, resulting in cracks of different degrees.

[0004] 2. Different deformations of different materials caused by temperature changes will lead to cracks under the beam. The linear expansion coefficients of the infill wall and the reinforced beam are different. When the temperature changes, the yield of the two materials is also different, resulting in cracks at the junction of the two materials. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a post-insertion chain block for an aerated concrete block wall, which solves the problems raised in the current background art.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A post-insertion chain block for an aerated concrete block wall includes a wooden wedge. The wooden wedge is trapezoidal. A small groove is opened in the middle of the inclined surface at the top of the wooden wedge, and a No. 10 iron wire is embedded in the small groove to form a chain-like object. The distance between the wooden wedges in this chain-like object is equal to the length of the block, and each chain is connected to 2 wooden wedges.

[0008] Preferably, the size of the wooden wedge depends on the size of the joint. The length is set to 50 mm, the lower bottom is set to the height of the reserved joint + 1 mm, the upper bottom is set to the height of the reserved joint - 1 mm, and the height is set to half of the wall thickness.

[0009] Preferably, the wooden wedge is taken out and dried after being soaked in a preservative for 24H.

[0010] Preferably, the width of the small groove is equal to the diameter of the No. 10 iron wire.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] A chain block for post-insertion opening of aerated concrete block wall provided by the utility model controls the left and right positions of the wooden wedges by setting wooden wedges. When the aerated concrete block wall is built up to the bottom of the beam or slab, a gap of 30mm - 50mm is left. After the wall deformation is stable for 14 days, the gap is blocked. First, wooden wedges are driven in turn from both sides of the reserved gap at the top of the masonry, and at the same time, No. 10 iron wires are tightened. After the wooden wedges are filled, the remaining gaps are blocked with fine aggregate concrete or mortar mixed with an expansion agent. Since there are two No. 10 iron wires between two wooden wedges, it can ensure that the concrete or mortar with large fluidity can easily be embedded into the gaps without flowing out, thus ensuring the compactness of the concrete itself, saving the formwork, time and labor. At the same time, it plays the role of an anti-joint ring longitudinally, effectively controlling the vertical cracks of the concrete, and is applicable to the post-insertion of lightweight aerated concrete block walls of high-rise or multi-story buildings.

[0015] To further illustrate the embodiments, the utility model provides drawings, which are part of the disclosure of the utility model. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0016] According to an embodiment of the utility model, a chain block for post-insertion opening of aerated concrete block wall is provided.

[0017] Embodiment 1:

[0018] As shown in the accompanying drawings of the specification Figure 1 A chain block for post-insertion opening of aerated concrete block wall includes a wooden wedge 1. The wooden wedge 1 is trapezoidal. A small groove 2 is formed in the middle of the inclined surface at the top of the wooden wedge 1, and a No. 10 iron wire 3 is embedded in the small groove 2 to form a chain-like object. The distance between the wooden wedges 1 in this chain-like object is equal to the length of the block, and each chain is connected with 2 wooden wedges 1.

[0019] Embodiment 2:

[0020] As shown in the accompanying drawings of the specification Figure 1As shown in the figure, there is a chain block for post-insertion opening in an aerated concrete block wall. By setting a wooden wedge 1, when the aerated concrete block wall is built up to the bottom of the beam or slab, a gap of 30 mm to 50 mm is left. After the wall deformation is stable for 14 days, the gap is then blocked. First, the wooden wedges 1 are driven in successively from both sides of the reserved gap at the top of the masonry, and at the same time, the No. 10 iron wire 3 is tightened to control the left and right positions of the wooden wedges 1. After the wooden wedges 1 are filled, the remaining voids are sealed with fine aggregate concrete or mortar mixed with an expansion agent. Since there are two No. 10 iron wires 3 between the two wooden wedges 1, it can ensure that the concrete or mortar with high fluidity can easily be embedded into the voids without flowing out, thus ensuring the compactness of the concrete itself, and also eliminating the formwork, saving time and effort. At the same time, it plays the role of an anti-joint ring longitudinally, effectively controlling the vertical cracks of the concrete, and is applicable to the post-insertion of lightweight aerated concrete block walls in high-rise or multi-story buildings.
