Background technique

The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce engineering costs. The building formwork structure used in the construction of cast-in-place concrete structures is mainly composed of three parts: panels, support structures and connectors. The panel is the load-bearing slab that directly contacts the freshly poured concrete; the support structure is a temporary structure that supports the panel, concrete and construction loads, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is the connection between the panel and the support Fittings that connect structures into a whole.

What present connector often adopts is pull bolt, formwork and support corrugated are fixed by pull bolt, and then concrete wall is poured. However, this connection method is not ideal for clamping and fixing the formwork. If the nuts on the pull bolts are tightened too tightly, the tension will be too large and the formwork will be squeezed and deformed by the supporting steel corrugation. The formwork is easy to fall off; and because the screw rod passes through the concrete wall, the water is easy to penetrate along the screw rod, and the corrosion of water to the reinforced concrete is the most terrible, which will seriously damage the stability and safety of the concrete wall ; Some projects use water-stop bolts for connection. Although the water-stop bolts can play a certain waterproof function, it is necessary to saw off the two ends of the wall and leave the middle section in the wall to ensure the impermeability of the wall. , It is very troublesome to dismantle, and the sawn off water stop screw cannot be reused. For this reason, a formwork connector for building wall construction is proposed.
