Description

Screw connection two-way variable tool type ground beam fixture

technical field

The utility model relates to a two-way variable tool-type ground beam fixture connected by a screw rod, which belongs to the strengthening technology of cast-in-place concrete ground beam formwork, and is suitable for pouring reinforced concrete ground beams of various sizes.

Background technique

The side formwork of the existing ground beam formwork is generally supported by steel pipe outer corrugations, the upper part of the formwork is fixed by steel pipe buckles or tension bolts, and the lower part is tensioned by tension bolts. This method has low work efficiency, and holes need to be drilled on the formwork at the place of the pull bolts, which affects the service life of the formwork. At the same time, because the beam width of the ground beam is usually large, there is not enough working surface for the lower pull bolts to be taken out, which increases the construction cost. If the combined fixing fixture is used, the work efficiency can be increased, it is safe and reliable, and it can be green and energy-saving.
