Description

[Detailed description of the invention] Industrial application field This invention relates to a wire mesh formwork used for pouring and curing concrete.

Conventional technology Conventionally, there has been a widely used method of constructing concrete structures by erecting columns facing each other and separating them for a certain period of time, placing wire mesh in parallel on both sides between the columns, and pouring concrete between the wire meshes. It has been implemented.

A problem with such formwork is that during concrete pouring, concrete overflows from the lower end of the wire mesh and adheres to the supports and end pieces. The overflowing concrete not only greatly damages the appearance of the structure, but also makes it difficult to remove the supports and end pieces later.

Purpose of the invention This invention solves the above problems and provides a wire mesh formwork that prevents concrete from overflowing from the wire mesh after pouring, facilitates the overall construction, and is highly economical. purpose.

Structure of the invention This invention is a wire mesh formwork consisting of a wire mesh, a post set up on the outside of the wire mesh, and a thick piece of wood to support the support. Alternatively, a substantially meshless outflow prevention portion is formed.

The embodiment of the outflow prevention part is as follows.

A band-shaped outflow prevention section made of paper, resin, cloth, rubber, etc. is stretched over the lower end of the wire mesh to form the outflow prevention section.

When manufacturing the wire mesh, a thin steel plate without mesh processing is formed integrally with the mesh part, and the thin steel plate is used as an outflow prevention part.

The lower end of the wire mesh is processed to have a mesh part finer than the upper mesh part by a predetermined height to form the outflow prevention part.

Embodiments This invention will be explained below based on embodiments shown in the drawings.

Figure 1 shows the wire mesh formwork in this invention.
A formwork consisting of a wire mesh 1, a pillar 3 supporting the wire mesh 1, and a thick end material 4 is erected facing each other, and is separated for a certain period of time by a spacing holder through a hollow steel pipe with a thick outer end on the outside of each. It is assembled.

A band-shaped outflow prevention piece 2a is attached to the lower end of the wire mesh 1 by a predetermined height to form a outflow prevention section 2. The outflow prevention piece 2a is made of water-resistant paper, resin, cloth, rubber, etc., and is attached to the wire mesh 1 with metal fittings, adhesive, etc., and is formed on either the inside or the outside of the wire mesh depending on the work situation. Since the outflow prevention part 2 is provided at the lower end of the wire mesh in this way, concrete will not overflow from the wire mesh after pouring.

In addition to the above, examples of the wire mesh used in this invention are shown in FIGS. 2 and 3.

The wire mesh 1 shown in FIG. 2 is manufactured by forming a thin steel plate 2b which is not meshed integrally with the mesh portion to form the outflow prevention portion 2.

In the embodiment shown in FIG. 3, the outflow prevention part 2 is formed by processing the lower end of the wire mesh 1 into a mesh part 2c that is finer than the upper mesh part by a predetermined height.

Effects of the invention This invention has the above-mentioned configuration, and since concrete does not overflow from the wire mesh after concrete is poured, the appearance of the structure is not damaged. Also,
Since slag does not adhere to end pieces or pillars,
Formwork removal work after concrete curing is easy.

Furthermore, during assembly, the outflow prevention pieces can be simply formed on the conventional wire mesh for formwork, so the installation work is simple. Furthermore, it has many advantages such as low construction costs, making it extremely practical.
