Description

Wooden formwork fixing device

Technical Field

The utility model belongs to the technical field of the construction, concretely relates to plank sheathing fixing device.

Background

In the construction process of constructional engineering, the forming of a concrete structure is mainly formed by erecting a wood formwork, the concrete structure is usually designed into multiple layers according to needs, and pouring construction is carried out from bottom to top, so that an interlayer construction joint L exists between an upper layer and a lower layer. In the construction process of concrete structure walls, columns and other members outside the building, wooden templates are also required to be erected for supporting. And after the lower-layer concrete reaches the form removal strength, removing the lower-layer concrete pouring wood formwork, and then erecting the upper-layer concrete pouring wood formwork. The upper concrete pouring wood formwork located on the outer vertical surface side of the building needs to shield the interlayer construction joint L, the upper concrete pouring wood formwork is firmly fixed at the interlayer construction joint L, and the upper concrete pouring wood formwork needs to be tightly lapped with the outer side surface of the lower concrete structure to meet the requirement of erecting the wood formwork in engineering construction and ensure the forming quality of the concrete member.

In the current common practice of construction site, as shown in fig. 1-2, a lower layer concrete pouring wood formwork 1 is erected and encloses a pouring space 101. Drilling holes at the upper part of the lower layer concrete pouring wood formwork 1 positioned on the outer vertical surface side A of the building for installing the horizontally arranged embedded screw rods 3, wherein one end of each embedded screw rod 3 is positioned in the pouring cavity 101, and the other end of each embedded screw rod 3 is positioned on the outer vertical surface side A of the building. And pouring concrete into the pouring space 101, and removing the lower-layer concrete pouring wood formwork 1 after the lower-layer concrete structure 102 reaches the demolding strength. And after demolding, the embedded screw rod 3 is used for supporting and fixing the lower end position of the upper concrete pouring wood template 2. Because the wood template is provided with the back edge, the wood template and the back edge are generally connected into a whole by nails, the thickness of the wood template is about 100mm, a phi 48 steel pipe is used as a main edge during fixing, and then the wood template is fixed by a wood template tie screw rod. Therefore, the length of the embedded screw rod 3 is about 200mm.

In order to remove the lower concrete pouring wooden form 1 positioned on the building outer vertical surface side a by using the embedded screw rods 3, the lower concrete pouring wooden form 1 needs to be withdrawn about 300mm from the building outer vertical surface side a to be smoothly taken out. On the other hand, in the scaffold installed on the building facade side a, since the specification of the distance from the inside of the scaffold to the building facade side a is required to be about 250mm, the lower concrete-poured wooden form 1 is attached and detached by interference of the scaffold, and therefore, it is necessary to adjust the steel pipe interfering with the inside of the scaffold and then attach and detach the lower concrete-poured wooden form 1. Therefore, the concrete pouring wooden formwork located on the building outer vertical face side a is inconvenient to erect and construct, and particularly, the concrete pouring wooden formwork located on a gable part is large in area, difficult to construct and high in potential safety hazard.
