Description

A reusable drop plate area support

Technical Field

The utility model belongs to the technical field of building construction, and in particular relates to a reusable support within a drop plate area, which is suitable for supporting within the drop plate range of a sunken toilet in a high-rise residential building.

Background Art

In recent years, more and more ground-floor and high-rise residential buildings have adopted sunken toilets with a structural drop of 300 to 500 mm. It is difficult to support the side formwork in this drop area, so wooden formwork is usually used for installation, and water-stop screws are reinforced with iron wire. However, the concrete molding quality formed by this method is poor and there is a risk of mold expansion.

Summary of the invention

The purpose of the utility model is to overcome the problems and shortcomings of the above-mentioned prior art and provide a reusable support for the lowering plate area that is simple to make and reusable. The utility model uses common materials on the construction site, is easy to make, has a simple structure, is easy to operate, and can be repeatedly used.

The technical solution adopted by the utility model is:

A reusable support in the drop plate area includes a steel pipe, vertical steel bars and diagonal bracing steel bars, and is characterized in that the vertical steel bars and diagonal bracing steel bars are welded in a triangular axil form at both ends of the steel pipe to form a reusable internal support device for supporting the side formwork at the drop plate position.

The inner support device is composed of steel pipes with triangular reinforcement welded at both ends, arranged at reasonable intervals according to the size of the drop plate, and vertically cross-installed in the drop plate area.

The steel pipe has a diameter of 48.3 mm and a wall thickness of 3.6 mm.

The steel bars are of model HRB400, with a diameter of 25 mm, and the vertical steel bars are close to the side formwork wooden beams.

The included angle between the vertical reinforcement and the diagonal reinforcement should be 45° to 60°.

The welding of the steel bars and the steel bars, and the steel bars and the steel pipes adopts submerged arc pressure welding.

The utility model discloses the side formwork support of the small drop-down plate position is used, adopts the common materials in the construction site, is easy to manufacture, has the simple structure, is easy to operate, and can be repeatedly used. After the formwork is completed, the inner support device is placed in the drop-down plate area to form a stable support system. After the concrete is poured and the strength requirement is met, the device can be removed. It is convenient to reuse the drop-down plate position of the same type of building and multi-storey standard floors. At the same time, it can better ensure the molding quality of the concrete drop-down plate, meets the green environmental protection requirements, and has good economic and social benefits.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG1 is a schematic structural diagram of the utility model.

In the figure: 1-steel pipe, 2-vertical steel bar, 3-diagonal bracing steel bar

DETAILED DESCRIPTION

The utility model is described in detail below with reference to the accompanying drawings:

As shown in Figure 1, the utility model includes a steel pipe 1, vertical steel bars 2 and diagonal bracing steel bars 3, and is characterized in that: the vertical steel bars 2 and diagonal bracing steel bars 3 are welded in a triangular plus axillary form at both ends of the steel pipe 1 to form a reusable internal support device for supporting the side formwork at the drop plate position. The internal support device is composed of a steel pipe 1 with triangular plus axillary steel bars welded at both ends, which is arranged at a reasonable spacing according to the size of the drop plate and vertically cross-installed in the drop plate area. The diameter of the steel pipe 1 is 48.3mm and the wall thickness is 3.6mm. The model of the steel bars is HRB400, with a diameter of 25mm, and the vertical steel bars 2 are close to the side formwork wooden beams. The angle between the vertical steel bars 2 and the diagonal bracing steel bars 3 is preferably 45° to 60°. The welding form of the steel bars and the steel bars, and the steel bars and the steel pipe is submerged arc pressure welding.

The device of the utility model can be manufactured by specific workers at a construction site.

To use the utility model, one needs to be familiar with the drawings in advance, count the size and height of the drop plate, determine the sizes of the steel pipe 1, the vertical steel bars 2 and the diagonal bracing steel bars 3 for layout, and after the side formwork construction is completed, use the back rib wood beams on the upper part of the side formwork as supports for installation and positioning, and the vertical steel bars 2 are fitted with the upper and lower wood beams of the side formwork to support the side formwork. After the concrete pouring is completed and the strength requirements are met, the device can be removed, which is convenient for repeated use of the drop plate position in the same type of buildings and multi-storey standard floors. At the same time, it can better ensure the molding quality of the concrete drop plate, meet green environmental protection requirements, and have good economic and social benefits.
