Description

Technical Field

[0001] The utility model relates to the technical field of building formwork, and particularly relates to an aluminum formwork reinforcement device for the position of building expansion joints. Background Art

[0002] Building expansion joints play a role in preventing cracks or damage to building components due to temperature changes. In high-rise industrial and civil buildings, the width of deformation joints is usually 150 - 300 mm. When the length of the outer wall at the expansion joint is relatively large, operators cannot reinforce the aluminum formwork point by point, which has a great impact on the construction quality and safety.

[0003] There are mainly two existing construction methods for expansion joint aluminum formwork: one is to fill the expansion joint with extruded polystyrene boards and pour the walls on both sides of the expansion joint integrally. Since the extruded polystyrene boards cannot be fixed, they are likely to float and displace during concrete pouring, resulting in the expansion joint being filled with concrete and the walls on both sides of the expansion joint becoming one body, which not only wastes concrete but also affects the construction quality of the expansion joint.

[0004] The other is to use large steel formwork for construction at the expansion joint. This method requires additional procurement of large steel formwork, and the turnover of large steel formwork is poor after use, which is not conducive to cost control. Moreover, holes need to be drilled on the steel formwork for passing through the tie bolts, and it is difficult to control the construction accuracy. Summary of the Utility Model

[0005] In view of the above technical problems, the utility model provides an aluminum formwork reinforcement device for the position of building expansion joints.

[0006] The technical solution is as follows: it includes a number of aluminum formworks connected in sequence at the head and tail, and adjacent two aluminum formworks are fixedly connected by installation bolts;

[0007] A number of groups of back rib assemblies are arranged on the aluminum formwork. Each group of back rib assemblies includes two parallel back ribs, and a number of groups of reinforcement units are arranged between the two back ribs;

[0008] The reinforcement unit is detachably connected to the aluminum formwork.

[0009] Preferably, the reinforcement unit includes a fixing bolt, a fixing nut is threadedly connected to the fixing bolt, and the fixing bolt is detachably connected to the aluminum formwork;

[0010] One end of the fixing bolt away from the fixing nut is fixedly provided with a connecting rod, a thread is arranged on the connecting rod, and a fastening nut is threadedly connected to the thread. The fastening nut is located above the back rib.

[0011] Preferably, the axis of the connecting rod is perpendicular to the axis of the fixing bolt.

[0012] Preferably, a backing plate is provided between the fastening nut and the backing rib.

[0013] Preferably, the fixing bolt and the connecting rod are fixed by welding.

[0014] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows: The aluminum formwork and the backing rib are connected into an integral whole by using the reinforcement unit, solving the problem of the integrated construction of the aluminum formwork at the expansion joint position, ensuring the construction quality, improving the work efficiency, and reducing the construction cost.
