Description

Formwork system for constructing co-owner of concrete wall structure

The present invention relates to a formwork system using a unitized panel used when constructing a concrete wall, and in particular, without using a specially manufactured coowner formwork for forming a coowner part of a wall, by using an existing panel unit as it is. The present invention relates to a formwork system for constructing a coowner portion of a concrete wall having excellent reuse and field adaptability by easily configuring a formwork for constructing an inner coowner portion.

In general, in the construction of a structure such as a building, the construction of a concrete wall structure of a building, for example, by combining a plurality of panel units having a size of up to 600mm x 1200mm one sheet to form a wall panel, the wall By installing two panels in parallel at a predetermined distance and placing concrete between the two panels, a concrete wall structure is formed.

When the concrete wall structure is formed, the length of the assembly of the panel unit sequentially installed from the end of the building to be constructed does not necessarily coincide with the length of the building wall structure, so that the formation of the co-owner part in the formwork using the united panel It has always been a problem, which required a lot of effort and time in construction. In the conventional case, in order to form the co-owner formwork as described above, as shown in Figure 1, the co-owner construction formwork (1) is specially manufactured separately by the length of the panel unit (2) assembly with respect to the wall length By injecting wedges into the pin mechanism 3 in a state in which the pinning mechanisms 3 respectively provided at both ends thereof protrude through the frames of the side panel units 2, they are coupled to the pre-formed panel unit assembly to form the inner and outer sides. Complete the formwork.

However, the above-mentioned conventional formwork system has to form a wall formwork with a panel assembly using a panel unit, and then separately produce a coowner formwork having a wall coowner shape that is shorter than the length of the building wall and connect it to the wall formwork. As a result, a lot of management effort and time were required for construction, and since the length of the wall structure of the building varies from site to site, it is impossible to unitize the co-owner formwork, and once used in one site, the co-owner formwork can be reused in another site. It was impossible to rebuild the formwork to fit the length of the wall again. Therefore, the productivity of the formwork has been reduced, and once the co-owner formwork used in one site had an economic problem that is discarded as scrap metal. In addition, the small co-owner formwork that is manufactured separately and coupled to the wall formwork, since the movement of the position relative to the wall formwork may occur when the concrete is placed, the wall part using the co-owner form is not satisfactory for other walls It can be provided, and furthermore, it is difficult to make fine adjustments when installing the formwork, which takes a lot of time when the actual installation and demoulding. In addition, such a construction method takes a lot of time to install a small size co-owner formwork on the unit panel assembly (wall assembly), and also, when the formwork is demolished after the wall construction, the formwork falls and narrows. Local damage may occur at one edge.

Therefore, the present invention has been made to solve the above problems, without producing a separate nose holder formwork, regardless of the length of the building wall structure, using the existing panel unit as it is, the owner of the concrete wall structure An object of the present invention is to provide a formwork system for constructing a co-owner part of a concrete wall structure capable of forming a part.

It is another object of the present invention to provide a formwork system for constructing a co-owner part of a concrete wall structure that is economical and reusable at another site, and is easily demolded after formwork and casting is completed.

Still another object of the present invention is to provide a formwork system for constructing a co-owner part of a concrete wall structure capable of precise construction for constructing a reliable concrete wall surface and a solid formwork sufficiently resistant to the side pressure of construction and poured concrete. .
