Embodiment 1

[0033] refer to Figure 1 to Figure 2 , this embodiment discloses a method for strengthening an arc-shaped formwork at a joint between a beam and a rigid column, comprising the following steps:

[0034] Step 1: Customize the curved template 1 according to the design requirements;

[0035] Step 2: Bind the first horizontal reinforcement 3 and the second horizontal reinforcement 4 horizontally and parallelly on the two column main reinforcements 2 at the connection node between the bound beam and the column. In this embodiment, the first horizontal reinforcement 3 and the second horizontal reinforcement 4 The second horizontal bar 4 is a steel bar, and there is a distance between the first horizontal bar 3 and the second horizontal bar 4. In this embodiment, the two ends of the first horizontal bar 3 and the second horizontal bar 4 are all provided with facing The drag hooks (not marked in the figure), the drag hooks are all set on the column main rib 2, better ensure that the ...

Embodiment 2

[0043] refer to Figure 3 to Figure 4 In this embodiment, on the basis of Embodiment 1, there is also a wooden square 11 between the keel 5 and the arc-shaped formwork 1, and the side of the wooden square 11 close to the arc-shaped formwork 1 is provided with a matching arc-shaped formwork 1. The arc-shaped groove (not marked in the figure) increases the force-bearing contact surface between the wooden square 11 and the arc-shaped formwork 1, prevents the formwork from deforming, and further improves the engineering quality of the formwork.

Abstract

The invention discloses a method for reinforcing an arc formwork at a connection node between a beam and a rigid cylinder, comprising the following steps: step 1: customizing the arc formwork according to design requirements; step 2: two column main bars at the connection node between the beam and the cylinder Bind the first horizontal rib and the second horizontal rib horizontally and horizontally; Step 3: Install the arc-shaped formwork, and open through holes on the arc-shaped formwork; Step 4: Reinforce the arc-shaped formwork, and use the pair of tension fasteners to sequentially align the arc-shaped formwork. The keel on the outside of the formwork, the curved formwork, and the first horizontal rib and the second horizontal rib bound on the main bars of the two columns are pulled and fixed to form a whole. The advantage of the present invention is that the reinforcement method can fix the position of the main reinforcement of the column, and use the pair of tension fasteners to reinforce the arc-shaped formwork on the main reinforcement of the column at the connection node between the solid beam and the rigid cylinder, and the reinforcement The method is firm, does not deform the formwork, improves the engineering quality of the formwork, and also improves the on-site safety factor.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for reinforcing an arc-shaped formwork at a node connecting a beam and a rigid column. Background technique [0002] Reinforced concrete frame structure is the most widely used form of building structure today. Concrete engineering is an important part of this structure. Before pouring concrete, the formwork must be supported. The formwork and its reinforcement brackets should have sufficient bearing capacity, rigidity and stability. Nowadays, with the design of architectural aesthetics and visual impact in construction engineering, more and more special-shaped buildings are produced, so construction companies are required to improve their capabilities. Because of the fluidity and plasticity of concrete, the construction and reinforcement of concrete structure formwork is more difficult. . Specifically, in construction, for stiffened concrete columns, due...
