Description

Base bar for wall formwork installation {The base bar for wall concrete-forms}

The present invention relates to a foundation bar installed in the lower end of the inner wall formwork for the construction of concrete walls of a multi-story building, and more specifically, the inner wall formwork for wall construction, in which a plurality of formwork panels are usually extended by the length of the wall to the left and right. The present invention relates to a foundation scaffold for installing an inner wall formwork, which can adjust the height so that it can be installed precisely and reduce the inner wall installation time.

When constructing various buildings or structures, the concrete wall is formed by forming a mold such as a mold in which the interior space forms a wall, and then filling and curing concrete therein, and the above-mentioned 'frame' called 'forms' Is made by connecting a number of rectangular panels, commonly called unit formwork panels.

Thus, the formation of the wall begins with the installation of formwork, a form having an interior space for filling concrete by connecting a plurality of formwork panels.

Wood has been mainly used as a material for the conventional formwork panel for installing the formwork as above, but the formwork using the wood formwork panel is used in the formwork installation work because the connection assembly between the formwork panels is made by nailing or tightening of wires. It requires a lot of manpower and time, and also requires a lot of time and manpower for the demolition work of formwork after concrete curing.

In addition, the wooden formwork panel is reinforced with a rectangular wooden bar on the back of the plywood, but due to the characteristics of the wood it is easy to be deformed by the pressure of the concrete to be filled in the formwork, the larger the size of the wall, the tendency increases more As a result, the outer surface of the wall often fails to form a flat surface.

Therefore, in order to prevent the deformation of the wooden formwork panel as described above, there is an inconvenience to reinforce the formwork panels with a separate reinforcement before filling the formwork with concrete, the formwork panel during the installation and demolition process They are often deformed or broken, so that the number of times they are repeatedly reused is extremely limited, which shortens their lifespan.

In addition, the damaged wooden formwork panel was mainly treated by incineration, but recently, as the smoke generated during incineration acts as a pollution factor, it is pointed out that additional costs are added for the treatment.

Therefore, in order to solve the above problems of the formwork wood formwork panel, a metal formwork panel made of metal such as steel or aluminum alloy has been developed and used in various building construction sites, and its use range and scale are rapidly increasing. There is a trend.

The installation structure of the conventional wall construction formwork for wall construction using the various formwork panels as described above has the following problems.

1 is a partial perspective view and a cross-sectional view showing the installation structure of the inner wall formwork for wall construction.

As shown, when looking at the basis of the conventional wall formwork for wall construction, which is installed using a plurality of formwork panels, a plurality of formwork panels are generally spaced apart from each other so that the front of the wall facing each other (W) On each floor surface on which the front and rear inner wall formwork (11, 11 '), which are erected in a standing state, is placed, a wooden base (12) in which a plurality of wood boards or lumbers are laminated is installed, and the inner wall formwork (11) A plurality of horizontal supports (S1) and vertical supports (S2) for fixing the inner wall formwork is fixed to the rear surface of (11 '), and the upper corners of the back surface (T) for fixing the slab construction plywood (V) Is installed.

The wood base 12, which is the foundation of the inner wall formwork as described above, is installed at a constant height by appropriately stacking a plurality of woods such as plywood and lumber, so that it is difficult to flatten the side of the wood base that is in close contact with the wall. In addition, since the height is also not easy to adjust uniformly, the horizontal straightness of the inner wall formwork placed on it, that is, the time for matching the height of the inner wall formwork is lengthened, thereby reducing the workability of formwork installation.

In addition, because a large number of timbers are laminated, a gap is inevitably formed between layers or adjacent woods, and the gaps may cause concrete to soak up, which may result in undesired finishing of the wall surface. Wood attached to the back is difficult to reuse, or it is necessary to remove the attached concrete for reuse, which makes cumbersome preparation of timber based wood.

The present invention was devised to solve all the problems of the conventional wood foundation that is the foundation of the inner wall formwork as described above, is installed directly on the floor and easy to adjust the height, the upper surface is coupled to the inner wall formwork bottom systemization It is an object of the present invention to provide a foundation bar that can accurately match the horizontal straightness of the inner wall formwork, iterative reuse is possible, as well as to reduce the installation time of the inner wall formwork.
