Expansion joint formwork tool

Technical field:

The utility model relates to the field of expansion joints and narrow space construction in the construction industry, in particular to a formwork supporting tool for expansion joints.

Background technique:

During the construction of the construction project, the space between the expansion joints of the building or the new building and the existing building is very small. If the traditional wooden formwork is used for reinforcement, the space is small and there is no construction work surface. It is difficult for workers to enter the interior for construction, and the formwork is not only difficult It is also difficult to dismantle, which is labor-intensive and labor-intensive, resulting in a lot of material waste, and the appearance quality of concrete cannot be guaranteed; there are also construction methods that adjust on one side, but often the pull screw passes through the main formwork. As well as the keel, it is always difficult to avoid the time-consuming step of drilling holes on the keel, so a formwork tool that is easy to install and disassemble with simplified operation steps is needed to support and reinforce expansion joints and narrow spaces. The method is simple and convenient. Materials are reused many times.

It is characterized in that: the horizontal support rod and the vertical support rod are respectively composed of two square steels that are parallel to each other, a gap is set between the two square steels, and the intersection of the gap between the horizontal support rod and the vertical support rod forms a cross hole The main template is provided with a through threaded hole at the position corresponding to the cross hole, the pull screw is perpendicular to the main template through the threaded hole, and the two ends of the pull screw are provided with fixed clips.

The utility model uses the square steel parallel to each other to make the horizontal support rod and the vertical support rod, leaving a gap between the square steels, so that the horizontal support rod and the vertical support rod form a natural cross hole at the intersection. The cross hole can form a firm tenon-and-mortise structure with the counter-pull screw, which avoids the process of drilling holes on the keel in order to pass the counter-pull screw in the later stage, and effectively controls the displacement range of the counter-pull screw, thereby reducing the construction process and operation. Easy to disassemble.

As preferably, the further technical scheme of the present utility model is:

The main template is evenly provided with self-tapping screws, and the tips of the self-tapping screws penetrate into the frame to connect the main template and the frame. Therefore, welding the main formwork and the frame body is avoided, thereby facilitating disassembly and improving the reuse rate and construction efficiency.

The fixing card includes a butterfly card and a tightening nut. The tightening nut is fixedly connected to the center of the butterfly card. The horizontal width of the butterfly card is the same as the width of the vertical support rod, so that the fixed card can span both sides of the vertical support rod. The fixed position where the pull screw is stuck on one side of the skeleton

The top of the skeleton is evenly provided with semi-circular hoisting rings, and both ends of the hoisting rings are fixedly connected with the vertical support rods, so that the formwork can be easily hoisted to the construction site.

The main formwork is a square plank.

Detailed ways:

The present utility model will be further described below in conjunction with specific embodiments, the purpose is only to better understand the content of the present utility model, and the examples do not limit the protection scope of the present utility model.

As shown in Figure 1 and Figure 2: an expansion joint formwork tool, which is mainly composed of a main template 1, a frame body, a fixing card and a pair of pull screws 4, among which, the main template 1 is fixedly connected to the frame body, and the frame body is composed of A plurality of lateral support rods 2 and a plurality of vertical support rods 3 are vertically crossed and fixedly connected to each other. The lateral support rods 2 and the vertical support rods 3 are respectively composed of two square steels that are parallel to each other, and a gap is set between the two square steels. , the intersection of the gap between the horizontal support rod 2 and the vertical support rod 3 forms a cross hole, and the width of the gap can be slightly larger than the width of the pull screw 4, so that the position of the pull screw 4 can be better fixed, and the displacement range is too large.
