Description

Formwork for building walls / slabs

The present invention relates to a formwork used in the construction of walls and slabs, and in particular to allow the folding and supporting of the wall formwork while having a sufficient working space, to facilitate the installation and demoulding of the formwork, without having to install a separate support And it relates to a wall / slab construction formwork that can build the wall surface at the same time.

In general, in the construction of a structure such as a building, in the construction of a wall or floor of the building, the wall surface is formed by combining a plurality of formwork consisting of a unit panel having a size of up to 600 mm × 1200 mm, The slab is formed by supporting the support every about 1m using plywood and lumber, and is building the wall and the slab at the same time by placing concrete on the wall or the formwork formed slab surface. In addition, in order to maintain the height of the slab surface at the time of construction of the wall surface, the wooden board having a predetermined height is placed on the floor surface, and then formwork on it to form a wall surface.

Here, the conventional formwork for forming the wall surface or the slab surface is usually made of a configuration to fix the plywood to the steel frame forming a square frame, or fixed or, or after fixing the wood as a support member on one surface of the plywood itself, The unit panel is combined.

This construction method requires the operator to assemble the unit panel one by one, and the installation work takes a lot of time because of the small size of the formwork. There was an inconvenience in work that had to be ground and smoothed. In addition, in the formwork demoulding method after the construction of the wall, because the worker has to demould the corner part of the formwork with the iron skewer in the forced demoulding method, the formwork falls and damages the floor surface, and also the strength of the concrete floor surface. Not only has a serious effect, but also acts as a hazard for the worker when demoulding the formwork, which poses a safety problem. In addition, in the case where the face plate attached to the concrete surface is steel or plywood, after one layer of formwork is used, a separate cleaning operation such as oiling the face plate should be performed.

On the other hand, a large formwork of about 1200mm x 2400mm size of the formwork to cope with the height of the wall, and even to the wall length with only 3 to 4 plates, it is proposed that such formwork first install the wall formwork, After the concrete is poured and the walls are formed, the slab formwork is again installed, and the concrete is poured to apply the horizontal and vertical separation casting methods to form the slabs. The application of this method can solve some of the problems of quality and safety when the unit panel is used, but there is a problem that the strength of the joint surface between the wall and the slab is lowered. It should not be installed directly, but should be installed using equipment such as a tower crane. At this time, the communication between the tower crane operator and the worker on the ground is not made smoothly, and furthermore, fine adjustment is not easy when the formwork is installed, there is a problem that takes a lot of time when the actual installation and demoulding.

In addition, since the demolding time of the slab formwork is different due to the difference in the curing period of the wall and the slab, the problem of the large formwork forming one side of the conventional wall, that is, the problem caused by building the slab after building the wall, and also the wall Although and slabs can be constructed at the same time, they have a problem of reduced productivity because they can form a single wall by combining several plates with formwork.

In Korean Patent Application No. 96-72484 filed by the applicant of the present application to solve the above problems, the upper plate 101 and the lower plate 102 and the upper and lower plates 101 and 102 as shown in FIG. Hinge means 103 to allow folding of the support means, support means 104 for supporting the bottom surface while the upper and lower plates (101, 102) upright, and mounted on both ends of the upper and lower plates for easy transportation A formwork for building wall slabs consisting of casters 105 is proposed. The conventional formwork configured as described above forms the wall smoothly while simultaneously building the wall and the slab, and also facilitates the installation and demoulding of the formwork.

However, the conventional wall slab building formwork having the above structure prevents the operator's work because the support means is located on the work space of the bottom plate, and because the support means is fixed to the bottom plate by nails or the like, There is a problem that disassembly is not easy when demolding. In addition, since the conventional formwork is simply manufactured considering the formation of the wall, when building the slab as shown in Figure 1b, a separate slab panel 107 and the slab support mechanism 108 should be provided In addition, the slab support mechanism 108 has a problem that acts as a barrier to work.

Therefore, the present invention has been made to solve the above problems, the formwork is supported on the wall mounted state, it is possible to simplify the installation and demoulding of the formwork while maintaining the work space in the bottom plate as it is. The purpose is to provide a wall / slab formwork.

In addition, the present invention has a formwork structure capable of folding the upper and lower plates, it is another object to provide a wall / slab formwork that is easy to transport after demolding.

In addition, the present invention has another object to provide a wall / slab formwork that can simultaneously build the wall surface and the slab irrespective of the number of days of concrete curing, and can support the cured slab without the slab support mechanism.

In addition, the present invention is to provide a wall / slab construction formwork to improve the quality of the wall surface by improving the quality of the wall surface by forming a wall formwork baffle to a size corresponding to the size of the wall surface, the synthetic resin material on one surface There is a purpose.
