Problems solved by technology

[0004] This kind of structural column construction technology has great potential safety hazards: 1. During masonry construction, usually the external scaffolding has been removed. Hidden dangers; 2. After the concrete pouring of the structural column is completed, the risk of removing the formwork is greater than that during installation, and it is removed after installation, which is labor-intensive for workers and takes time and effort
In addition, when using step by step to strengthen the connection formwork, it is necessary to open holes in the brick body of the outer wall, which will cause damage to the integrity of the outer wall and increase the amount of work for sealing the hole (bubu tight is a new type of construction tool, It is composed of two parts, the hook-shaped lever and the movable card head)
In addition, the formwork at the junction of the blocks is not easy to support, which makes the installation of the formwork too troublesome. At this time, the scaffolding has been removed, and the drawing rods between the formwork on the outer facade and the inner facade are not easy to install. Workers have a greater safety hazard

Embodiment 1

[0033] The wall structure of the exempt construction column formwork provided by this embodiment, such as figure 1 , figure 2 and Figure 5As shown, it includes a formwork body, a reinforcement cage 3 arranged in the cavity of the formwork body and blocks arranged on both sides of the formwork body, and the formwork body is supported between the floor 1 and the frame beam 2 above the floor 1; The formwork body is composed of at least two standard sections placed up and down and vertically arranged. The standard section includes an outer clamping mold 4 vertically arranged on the outer facade of the wall and having a U-shaped transverse section and an outer clamping mold 4 arranged on the outer clamping mold 4. The opening end and the inner lining mold 5 forming a closed frame structure with the outer clamping mold 4 are provided with a U-shaped notch 51 at the upper end of the inner lining mold 5 located at the top standard section, and a In the bucket mold 6 that closes th...

Embodiment 2

[0046] A wall structure that avoids demolition of the structural column formwork, such as Figure 3 to Figure 5 As shown, it includes a formwork body, a reinforcement cage 3 arranged in the cavity of the formwork body and blocks arranged on both sides of the formwork body, and the formwork body is supported between the floor 1 and the frame beam 2 above the floor 1; The formwork body is composed of two formworks placed up and down and arranged vertically. Both the upper formwork and the lower formwork are composed of an outer clamping form 4 which is vertically arranged on the outer facade of the wall and has a U-shaped transverse section. And the inner lining mold 5 that is arranged on the opening end of the outer clamping mold 4 and forms a closed frame-like structure with the outer clamping mold 4. Wherein, the upper end of the lining mold 5 of the upper formwork is provided with a U-shaped gap 51, and a bucket mold 6 for closing the gap is arranged outside the U-shaped gap...

Abstract

The invention discloses a wall structure of a dismounting-free constructional column formwork and a construction method of the wall structure. The wall structure of the dismounting-free constructional column formwork comprises a form board body, a reinforcement cage and building blocks; the reinforcement cage is arranged in a cavity of the form board body; the building blocks are arranged on two sides of the form board body; the form board body consists of at least two vertical standard knots which are placed in the up-down direction; each standard knot comprises an outer clamping mold and an inner lining mold; each outer clamping mold is arranged on an outer vertical surface of a wall; the cross section of each outer clamping mold is U-shaped; each inner lining mold is arranged at an opening end of the corresponding outer clamping mold; each inner lining mold and the corresponding outer clamping mold form a closed-frame-shaped structure; a U-shaped notch is formed in the inner lining mold of the top standard knot; and a brick model is arranged outside the U-shaped notch. The construction method comprises the following steps of early-stage preparation, reinforcement cage binding and mounting, manufacturing and mounting of the standard knots and the brick model, reinforced bar mounting and building block masonry, and pouring molding. The wall structure of the dismounting-free constructional column formwork and the construction method of the wall structure have the advantages that the wall structure is convenient to mount, a form board does not need to be dismounted, and unnecessary potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the construction field of structural columns in building construction, in particular to a wall structure without dismantling of structural column formwork and a construction method thereof. Background technique [0002] In masonry construction, the blocks are usually laid over the slab and the structural columns are poured between the slab and the frame beams above the slab. The structural column has the advantages of improving the shear strength of the wall, improving the deformation capacity of the wall and the house, forming a whole with the block, effectively controlling the cracking of the wall, and enhancing the seismic strength of the wall. Especially in recent years, in order to improve the seismic strength of the wall, multiple horse-toothed bars are arranged at intervals on the structural column. This setting can improve the contact surface between the block and the structural column, thereby enhancing the integrity a...
