Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering construction, in particular to an arc-shaped concrete formwork reinforcement component. Background Art
[0002] Nowadays, with the increasing requirements for environmental protection, large sewage treatment tanks have been widely used in cities. Large-diameter circular sewage tanks are increasingly used. The formwork reinforcement of circular sewage tanks is a difficult problem encountered in construction. The conventional practice is to use narrow formwork splicing, and each narrow formwork is reinforced with double steel pipes and tension bolts. In this way, the main keel cannot be connected as a whole, and the phenomenon of concrete expansion is common, resulting in material waste and increased construction costs. Utility Model Content
[0003] The utility model provides a curved concrete formwork reinforcement component to solve the technical problems existing in the known technology. The component can effectively prevent the concrete formwork from expanding.
[0004] The utility model adopts the following technical scheme to solve the technical problems existing in the known technology: an arc-shaped concrete formwork reinforcement component, comprising a vertically arranged secondary keel and an adjustable chain-type main keel, the adjustable chain-type main keel comprising a plurality of fixing rods, two adjacent fixing rods on the left and right are connected by two upper and lower connecting rods, a limiting groove is provided at the end of the fixing rod, a vertically arranged stud is passed through the limiting groove, the stud is connected to the limiting groove through a sliding block, and the two connecting rods are hinged to the fixing rod through the stud; a clamping groove adapted to the secondary keel is provided on the inner side of the middle part of the fixing rod, the clamping groove is composed of two left and right groove-shaped claws, and the groove-shaped claw is slidably connected to the fixing rod; a tension bolt hole is provided on the fixing rod, and the tension bolt hole is coaxially arranged with the clamping groove.
[0005] The groove-shaped claw is slidably connected to the fixed rod through an L-shaped hook plate. A horizontal slide groove adapted to the L-shaped hook plate is provided on the fixed rod. The L-shaped hook plate passes through the horizontal slide groove and is hooked on the fixed rod.
[0006] The connecting rod and the fixing rod are both made of rectangular tubes.
[0007] The advantages and positive effects of the utility model are as follows: by adopting an adjustable chain-type main keel with a secondary keel slot, the secondary keel on the outer side of the arc-shaped concrete formwork can be effectively reinforced, thereby ensuring the stability of the formwork after assembly and effectively preventing concrete from expanding the formwork; by arranging limit grooves and horizontal slide grooves on the fixed rods, the spacing between the fixed rods and the opening of the slots can be adjusted, so that the adjustable chain-type main keel can be applied to a wider range.
