Description

Whole shaped steel formwork for bathroom caisson

technical field

The utility model relates to a shaped steel formwork, in particular to an integral shaped steel formwork for a toilet caisson, which belongs to the technical field of building construction.

Background technique

The caisson toilet is a sunken toilet. It refers to the partial or overall sinking of the bathroom structure layer from the corresponding floor to a certain height during the main body construction, so that the horizontal drainage pipes of the bathroom are buried in it, and then backfilled with light materials. The structure only needs to set a hole for the drainage standpipe to pass through use.

The caisson toilet can change the drainage pipe according to its actual needs, and it is a commonly used structural form in the development of commercial housing. At present, traditional wooden formwork is mostly used in the formwork construction of caisson toilets. Because the wooden formwork has low rigidity, poor flatness, and insufficient inner support strength, it is easy to cause quality problems such as poor molding dimensions and structural leakage.

Contents of the invention

The overall shaped steel formwork for the toilet caisson provided by the utility model has the advantages of simple processing and convenient construction, and can effectively overcome the deficiencies of the prior art.

The purpose of this utility model is achieved in that:

The overall shaped steel formwork of the bathroom caisson includes four side panels, four connecting rods, a tie rod, four lifting rings, and four jacking parts. It is characterized in that the four side panels are combined into an outer frame, and the four A connecting rod is respectively arranged at the corner of the outer frame to connect two adjacent side plates, the tie rod is connected to the two connecting rods, and the jacking member is arranged in the middle of the legs of the suspension ring and fixed on the corner of the outer frame. Describe the inner wall of the side panel.

The jacking part is composed of bolts, jacking arms and snap rings for removal.

The overall shaped steel formwork of the bathroom caisson has the following characteristics:

1. The template has high rigidity and the molding size is guaranteed;

2. Overall finalization, simple construction and high work efficiency;

3. Concrete molding is solid inside and outside, without leakage.

Detailed ways:

The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

The construction process of the overall shaped steel formwork of the bathroom caisson is shown in Figure 1.

Shaped steel mold design

According to the construction drawings of engineering buildings and structures, the size of each caisson toilet is reviewed to determine the size of the finalized steel mold. The height of the shaped steel mold should be 50mm higher than the height difference of the lowering plate. For the convenience of mold removal, the bottom opening of the steel mold is retracted by 20mm, so that the overall steel mold is inclined.

The shaped steel mold is formed by cold pressing of 3.0 thick steel plates. In order to ensure the integrity of the steel mold, L60*60*5 connecting rods and opposite pull rods are installed at the corners. The specific method is shown in Figure 2:

The four corners of the shaped steel mold are equipped with Φ20 pull rings that pass through the upper wing plate and are welded to the inner wall of the steel mold, and use the pull rings to fix the legs to set up the jacking parts. The practice is shown in Figure 3.

The jacking parts are welded by Φ30 bolts, jacking arms, and snap rings, and are used with a small manual jack to remove the overall steel mold. The jacking method is shown in Figure 4.

Shaped steel mold making

Purchasing raw materials and components according to the design drawings, the side panels of the shaped steel molds are processed and shaped in advance in the processing plant according to the designed size and shape, and assembled and welded on site. In order to prevent welding deformation, it should be assembled by spot welding first. After the connecting rods and tie rods are fixed by spot welding and the size and flatness are checked, large-scale welding should be performed.

After the welding is completed, the weld seam is polished, the inside of the shaped steel mold is painted with anti-rust paint, and the outside is painted with a release agent for later use.

Shaped steel mold installation

The support and reinforcement of the traditional wooden formwork adopts the tension bolt system, and the shaped steel formwork adopts the surrounding internal support system, and the formwork bracket is used to set up steel pipe diagonal braces on the outside to offset the lateral pressure of concrete pouring.

According to the elevation of the bottom edge of the bathroom hanging form, use the beam stirrups around the bathroom to weld Φ12 horizontal steel bars (at least 2 on each side, and the horizontal steel bars are required to exceed the beam edge control line by at least 50mm) as the bottom support of the shaped steel mold. Be careful not to burn the main reinforcement or stirrup during spot welding construction. After the construction of the elevation positioning reinforcement is completed, the shaped steel form can be hoisted and the plane positioning review can be carried out.

After the plane positioning review is completed, its plane position must be fixed to avoid deviation during concrete pouring. Fix two water-stop screw-type fixing parts on the bottom formwork of the floor slab around the hanging formwork, and support the hanging formwork in four directions at the same time to fix it.

Removal of shaped steel molds

After the concrete pouring is completed, the formwork can only be removed when the concrete strength reaches above 1.2Mpa.

The order of formwork removal is to loosen first and then disassemble. Use jacks to lift the lifting parts at the four corners of the shaped steel form one by one, so that the shaped steel form is completely separated from the concrete, and then use the lifting machine to lift the overall shaped steel form away from the operation floor.

After the shaped steel mold is dismantled, it should be cleaned in time and painted with release agent for the next use.
