Description

Assembly structure of building formwork {structure of flash board for the construction}

The present invention relates to the formwork field, and in more detail, when constructing a cement structure in the construction of various buildings, it relates to the assembly structure of the formwork forming the mold.

In general, since various cement structures are constructed during various constructions, formwork is an indispensable material for building constructions.

Recently, the use of formwork is gradually decreasing according to the development of construction technology of the building, but it is still widely used in the construction of small and medium buildings, and related technologies are also being steadily researched and developed.

Then, a brief look at the conventional formwork structure as follows.

A plurality of wood panels (4) made by sticking the wood (3) in the horizontal and vertical directions on the back of the rectangular plywood (2), and a plurality of wood panels in contact with the required area in the horizontal and vertical direction fixed and then fixed The other formwork assembly 9 is formed together with the one formwork assembly 8 so as to face each other in the spaced apart state.

When the one side and the other formwork assembly (8) (9) is facing each other, the plywood (2) constituting the wood panel (4) is to be placed inward and the lumber (3) outward.

Next, by holding the support posts 7 at appropriate intervals so as to support the outside of the one formwork assembly and the other formwork assembly 8, 9, the support posts hold both formwork assemblies 8, 9, The outer and inner deformations of the two formwork assemblies are prevented.

Subsequently, after drilling holes in the wood panel 4 of both formwork assemblies, a plurality of steel wires 6 are connected to the formed holes, and each of the steel wires is formed with one side formwork assembly and the holding post 7. Both formwork assemblies (8) (9) are supported to stabilize while preventing outward deformation and inside deformation of the other formwork assemblies (8) (9).

When the formwork 1 is assembled as described above, the concrete mixed with gravel in mortar is poured into the space between the formwork assemblies 8 and 9 formed on both sides of the formwork 1, and then, after a predetermined time passes. Since the concrete poured between the two formwork assemblies 8 and 9 is cured and solidified in a hard state, one cement structure 5 is completed.

On the other hand, when the concrete is poured into the space between the one formwork assembly and the other formwork assembly (8) (9) in the above process, the force to escape to the outside by the weight of the concrete itself in the process of filling the cast concrete Since the left and right gaps and the upper and lower gaps of the wood panel 4 constituting the formwork assemblies 8 and 9 on both sides will have a deformable force, in this case, the holding post 7 and the steel are provided separately. The formwork 1 is fixed by reinforcing the wire 6.

In order to firmly reinforce the space between the one side and the other formwork assembly (8) (9), a hole is first drilled through the assembly, and then the steel wires (6) are woven together through the holes and the ends of the steel wire Reinforcement is made so that the formwork 1 counteracts the load deformation force of the concrete by revolving with each other in the crossed state.

In addition, the mold 1 is further reinforced by being fixedly installed in the vertical direction by using the support base 7 having a large cross-sectional area at the outer surface of the one side and the other formwork 8, 9.

Then, when all the concrete is solidified, the formwork 1 forming the mold of the concrete is demolished. In this case, the protrusions of the steel wires 6 embedded and fixed in the concrete are first cut by using a tool such as a cutter. Then, the holding post 7 installed on the outer surface of the formwork 1 is dismantled.

In addition, the dismantling process of all the formwork is completed by removing the wood panel 4 attached to the lower part in the state where the dismantling of the props 7 is made.

As described above, after all the cement structures 5 have been constructed, all the construction work is completed by processing the wall as needed. Normally, the inner wall facing the interior is plastered with mortar or the like to have a smooth wall surface. A decorative tile is attached to the outer wall facing the wall to decorate the wall beautifully.

At this time, the state of the outer wall is very dirty by the protruding steel wire pieces and the concrete solidified to dry everywhere, so that the above-mentioned protrusions are removed and processed smoothly, and then the first connection member of the steel tile at regular intervals. The exterior construction of the entire cement structure is completed by attaching and installing a decorative tile separately provided to the tile first connection member in the state of being driven and fixed.

However, since the conventional wood panel hardens in the state of being confined with the concrete during the concrete curing process, it is very hard to remove the wood panel during the demolding process, and the surface of the cement structure is much damaged. .

After that, the contractor must perform the step of reinforcing the points because the appearance of the structure is much damaged, and the protruded steel wires solidified together in the concrete remain on the surface of the molded cement structure. Since the process of cutting and removing the old wire has to be performed, there are many improvements, such as not only a lot of residual damage, but also an unnecessary input of manpower, which extends the construction period.

In addition, the wood panel is squeezed with concrete during solidification, so that the board is broken due to excessive force when demolding, and the panel panels are damaged in many places in the process of connecting the steel wire as a connection pipe to the space between the formwork. There is a disadvantage that can not be reused many times.

In addition, the process of attaching the decorative tile to the outer wall of the cement structure is also performed by manual work to put the first connecting member every day, not only requires a lot of manpower, but also difficult construction and serious problems exposed to safety.

In order to solve the shortcomings of such wood panels, some steel plates are used. However, when the formwork is manufactured using iron plates, there is no damage to the structure when demolding, but the price of the steel plates is very expensive and heavy. It is very difficult to construct the formwork only by manual work, and deformation of the iron plate may be bent after concrete curing, which is not suitable for formwork.

In addition, the synthetic resin material has a smooth surface, does not deteriorate, and can be produced in a large amount in some cases, the use of this, but also the formwork material that requires precision and durability, which is not widely used.

The present invention has been made to solve the above-mentioned problems, to provide a building formwork having the convenience of construction while having excellent durability and stability by dualizing the formwork into the inner formwork and the outer formwork assembly There is a purpose.
