Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a quick-forming clamp used for frame column formwork. Background Art

[0002] At present, in the construction industry, column formwork reinforcement usually adopts a combination of steel pipes and through-wall tie rods. This reinforcement method has the following disadvantages: 1) The traditional reinforcement method requires the use of a combination of multiple materials. All materials need to be purchased separately and can only be used when the materials are fully configured; 2) The traditional reinforcement method requires a lot of complicated work such as punching, steel pipe connection, and tension screw connection, and the construction time is long; 3) Steel pipes are prone to bending after long-term use, and the error is large, and it is not easy to adjust the reinforcement specifications; 4) The traditional reinforcement method requires column penetration construction, which is easy to affect the quality of the concrete structure and the utilization rate of the reinforcement materials is low. 5) The materials of the traditional reinforcement method cannot be used multiple times. The materials need to be cut and trimmed for the reinforcement of square columns of different specifications, and there is a lot of material waste. 6) The tightening force of the nuts of the tension screws in the traditional reinforcement method is different, and the human influence factor is large, resulting in many quality risks after concrete pouring. Utility Model Content

[0003] The utility model provides a quick-forming clamp for frame-column formwork to solve the technical problems existing in the known technology. The clamp is easy to use and can be reused.

[0004] The utility model adopts the technical scheme to solve the technical problems existing in the known technology: a quick-forming clamp for frame column formwork, the clamp is composed of four groups of tie assemblies connected end to end, the tie assemblies include a U-shaped base plate, the tail of the U-shaped base plate is provided with a hook head, the side wall of the head is provided with a serrated limit slot, the limit slot is provided with an adaptive hook head limit rod, the hook head limit rod is vertically connected to the longitudinal adjustment rod, the longitudinal adjustment rod is threadedly connected to the adjustment sleeve, the adjustment sleeve is rotatably connected to the connecting rod, the connecting rod is vertically fixed to the hinge shaft, the hinge shaft is installed on the side wall of the U-shaped base plate near the tail, and the connection structure of two adjacent tie assemblies is: the hook head of the tie assembly I hooks the limit slot part of the tie assembly II, and the hook head limit rod of the tie assembly II is arranged on the outer side of the upper hook head of the tie assembly I and is clamped in the corresponding limit slot.

[0005] The advantages and positive effects of the utility model are as follows: during installation, the ends of the tie assembly are hooked, and then the adjusting sleeve is rotated to make the hook head limit rod close to the outside of the hook head to limit it. The operation is simple, and the reinforcement of the frame column formwork beam can be completed quickly, and the installation efficiency is high. During disassembly, the adjusting sleeve is rotated to make the hook head limit rod away from the outside of the hook head, and then the connection between the two adjacent groups of tie assemblies is released. The operation is simple, and it can be reused, and the utilization rate is high. The effective tie length is adjusted by a spiral transmission mechanism, which is convenient to adjust and has high adjustment accuracy. The tie assembly has a complete structure, is not easy to lose, is easy to store, and is easy to use. When the utility model is used to reinforce the frame column formwork beam, there is no need to use through-wall bolts. The column surface is smooth after demoulding, and no trimming and secondary plastering operations are required, which can save labor and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS
