Description

A stable floor steel support

technical field

The utility model relates to a building steel bar support, in particular to a stable floor steel bar support.

Background technique

The horse stool is indispensable as a measure in the construction process of reinforced concrete slabs, and sometimes it is also very important from a technical and economic point of view. It is shaped like a stool, so it is commonly called a horse stool, also known as a brace. It is used in the middle of the steel bars of the upper and lower floors, and plays the role of fixing the steel bars of the upper floor. At present, construction workers in the construction industry mostly use simple horse stools made on the construction site when supporting the upper reinforcement on the slab. Easy to rust and other shortcomings. In order to ensure the construction quality, the construction personnel adopted measures such as welding to increase its stability, which wasted a lot of manpower and material resources; when no welding was used, the simple horse stool could easily slip off the bottom steel bar, thus losing the function of the horse stool. With the development of society and the fierce competition in the construction market, the requirements for saving and better reducing construction costs are higher. The traditional simple reinforced horse stool supports are poor in firmness and stability, and cannot meet the requirements of construction loads.

Contents of the invention

The utility model provides a stable floor steel bar support for solving the technical problems in the known technology. The support is firm and stable, and the distance between the upper and lower steel bars on the floor can be guaranteed.

The technical solution adopted by the utility model to solve the technical problems existing in the known technology is: a stable floor steel support, including the top surface supporting the upper floor steel bar, the bottom foot supported by the lower floor steel bar and connecting the support The vertical neck of the top surface and the bottom foot, the support top surface is formed by n-shaped steel bars arranged obliquely, and the closed end of the n-shaped steel bar is a free end; the vertical neck is formed by the The opening end of the n-shaped steel bar is formed by bending and extending downward; the foot part is formed by bending and extending the vertical neck in a horizontal direction away from the supporting top surface.

The bracket is an integrated steel bar bending structure.

The included angle between the support top surface and the vertical neck is 110°-135°.

The utility model has the advantages and positive effects: the support is firm, the stability is good, it can withstand various construction activity loads, and the spacing between the upper and lower steel bars on the floor can be guaranteed; and the utility model is simple in structure, easy to manufacture, and convenient to use. Can produce better social and economic benefits.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1, a kind of stable floor reinforcement support 1, comprises the top portion 2 that supports the upper floor reinforcement, the foot portion 3 that is supported by the lower floor reinforcement and the plumb neck that connects described support top portion and bottom foot portion 4. The support top surface 2 is formed by inclined n-shaped steel bars, the closed end of the n-shaped steel bars is a free end; the vertical neck 4 is formed by the open end of the n-shaped steel bars It is formed by bending and extending; the bottom foot portion 3 is formed by bending and extending the vertical neck 4 in a horizontal direction away from the supporting top surface 2 .

In Figure 1, L1 is the length of the foot part 3 = 150mm, L2 is the spacing between the upper and lower steel bars on the floor = plate thickness - 2 × steel bar cover thickness - 2 × steel bar diameter, L3 is the length of the top surface of the support = 120mm, L4 is the bottom The distance between the supporting feet of the feet is slightly larger than the diameter of the steel bar, and α is the angle between the top surface of the support and the vertical neck, and the angle is 110°-135°.

The implementation process of the present utility model is:

Please refer to Figures 2 to 3. After the upper and lower layers of steel mesh are bound, put the above-mentioned bracket 1 in, place the foot part 3 on the lower layer of steel bars 5, and bind and fix them. The upper layer of horizontal steel bars 6 and the upper layer of longitudinal steel bars 7 intersect. Press on top of the support top surface 2 of the bracket.

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative and not restrictive. Under the enlightenment of the utility model, those skilled in the art can also make many forms without departing from the purpose of the utility model and the protection scope of the claims, and these all belong to the protection scope of the utility model.
