Building formwork forming structure, fasteners and construction method of building formwork

Abstract

The invention relates to a building formwork forming structure, a fastener used for the structure and a construction method, belonging to the formwork technology for concrete pouring in the construction industry. Its building formwork forming structure includes templates, tensioning screws, reinforcing ribs and clamps. The templates are arranged on both sides of the concrete filling cavity in parallel. There are one pair of tensioning bolt holes set opposite to each other on the formwork. The two ends of the pull bolts are matched, and the two ends of the pull bolts are threaded to connect a pair of frustum-shaped fasteners; the frustum-shaped fasteners are arranged on the inside of the two templates, and the large end faces of the frustum-shaped fasteners facing the outside are arranged There is an extended screw that can pass through the hole of the pull bolt on the template; the protruding part of the extended screw passes through the column on the outside of the template and is tightened and fixed by a conventional clamp. The structure and method of the invention reduce the waste caused by cutting the ends of the pull bolts in the traditional structure, and simultaneously simplify the construction and improve the efficiency.

[0001] technical field [0002] The invention relates to a building formwork forming structure, a fastener used for the structure and a construction method, belonging to the formwork technology for concrete pouring in the construction industry. Background technique [0003] At present, there are many fixing structures and construction methods for construction formwork. There are mainly two types in the prior art. One is to directly fix with bolts, and then use gas cutting or electric welding to cut off the screw rods exposed to the concrete surface after the formwork is removed. Increase the cost of gas cutting or electric welding in the process of use and the cost of the screw cut off at both ends; the second is to fix the bolts with plastic sleeves, pull out the bolts after demoulding, and then fill the mortar or inject sealant, and use the injection sealant to fill Because the cost of the sealant is much higher than the cost of bolts when plugging the gap, it will still c...

[0003] At present, there are many fixing structures and construction methods for construction formwork. There are mainly two types in the prior art. One is to directly fix with bolts, and then use gas cutting or electric welding to cut off the screw rods exposed to the concrete surface after the formwork is removed. Increase the cost of gas cutting or electric welding in the process of use and the cost of the screw cut off at both ends; the second is to fix the bolts with plastic sleeves, pull out the bolts after demoulding, and then fill the mortar or inject sealant, and use the injection sealant to fill Because the cost of the sealant is much higher than the cost of bolts when plugging the gap, it will still cause waste of construction cost. Although the use of plugging mortar to plug the gap can effectively solve the problem of high construction cost, this kind of mortar itself is Defects make the voids unrealistically filled, and the casing holes are covered only by the plaster layer, resulting in a series of problems such as energy saving, sound insulation not up to standard and leakage, and the construction quality cannot be guaranteed
