Description

A kind of assembling system and assembling method of shear wall formwork

technical field

The invention relates to the field of construction, in particular to an assembling system and an assembling method of a shear wall formwork.

Background technique

Shear walls are also called wind-resistant walls, seismic walls, and structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads caused by wind loads or earthquakes. Prevents structural shear damage. It is divided into plane shear wall and cylinder shear wall. Planar shear walls are used in reinforced concrete frame structures, raised slab structures, and beamless floor systems. In order to increase the rigidity, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or prefabricated in some parts. The cast-in-place shear wall and the surrounding beams and columns are poured at the same time, and the integrity is good. Cylinder shear walls are used in high-rise buildings, high-rise structures and suspension structures. They are surrounded by partition walls of elevator rooms, stairwells, equipment and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls. The strength is higher than that of the plane shear wall and can withstand larger horizontal loads. Walls can be divided into load-bearing walls and shear walls according to their stress characteristics. The former mainly bears vertical loads, such as masonry walls; the latter mainly bears horizontal loads. In the seismic fortification area, the horizontal load is mainly generated by the horizontal earthquake action, so the shear wall is sometimes called the seismic wall. According to the structural materials, shear walls can be divided into steel plate shear walls, reinforced concrete shear walls and reinforced block shear walls. Among them, reinforced concrete shear walls are the most commonly used.

Shear wall formwork is an important formwork form in reinforced concrete structures. The installation method of shear wall formwork with holes drilled on the formwork has been used for a long time on the construction site, but the existing method has the disadvantage that the formwork is not easy to remove, and it is easy to cause the formwork to be damaged when the formwork is removed. Therefore, the reuse rate of the formwork is low, the fixing effect of the formwork is poor, and it is easy to cause displacement during pouring, resulting in damage to the wall structure of the shear wall, and the internal stress cannot meet the requirements.

Contents of the invention

The technical problem to be solved by the present invention is that the formwork in the existing method is difficult to dismantle, and the formwork is easily damaged when the formwork is removed, so the formwork reuse rate is low, the formwork is poorly fixed, and it is easy to generate displacement during pouring, resulting in failure of the shear wall. The wall structure is damaged, and the internal stress does not meet the requirements. The purpose is to provide an assembly system and an assembly method for the shear wall formwork.

After being tightened by the tensioning mechanism, the concrete between the formworks will be more stable and will not be displaced, so that the formed shear wall structure meets the set requirements. The stress is stable, and the template will not be damaged, and can be reused repeatedly.

The tensioning mechanism includes a compression cover, a screw rod and a locking nut. The compression cover is pressed on the transverse pressure rod, and the end face of the compression cover is concaved to form two sets of arc surface grooves.

The longitudinal pressing bar set in each pressing bar groove is a A hollow steel pipe is clamped with the outer wall of the horizontal pressure rod through the arc groove on the compression cover, and the screw is tightened after passing through the compression cover to ensure the fixed position of the formwork, and the concrete will not be deformed after pouring. The stress is stable, and the template will not be damaged, and can be reused repeatedly.

The formwork group is generally divided into two sets of parallel settings, each formwork group is composed of multiple formworks, and then the battens and attached plates fixed as a whole structure are arranged between adjacent formworks, and the battens are kept in contact with the templates. In the same vertical plane, the attached plate is attached to the adjacent formwork, the longitudinal compression bar is snapped into the compression bar groove, the horizontal compression bar is set on the surface of the longitudinal compression bar, and the center line of the horizontal compression bar and the longitudinal compression bar The center line is vertical, and each group of horizontal pressing rods and the corresponding pressing strips are set at the same height, and the pressing cover is pressed on the corresponding horizontal pressing rods, and the outer wall of the horizontal pressing rods is kept embedded in the arc groove, and then the screw passes through After compressing the cover, pass through the screw holes between each group of horizontal pressing rods, and the two ends of the screw rods are arranged outside the two template groups, and the locking nuts are screwed on the screw rods to complete the assembly.
