Description

{Panel for construction mold}

[0001] The present invention relates to a mold, and more particularly, to a wall which is easily deformed by a synthetic resin material and which is in contact with a concrete to be laid, To a wall mold that can be used for construction.

Generally, walls, slabs and pillars of buildings are made of concrete. If you look at the construction process, you first install the formwork and pour concrete into it. After curing the poured concrete, the construction is completed by dismantling the installed formwork. Such a mold has been conventionally disclosed in Japanese Patent Laid-Open No. 10-2012-0108581.

The mold is mainly formed of a wood panel (plywood) having excellent bending stress. Since the wood is not waterproof and durable due to the characteristics of the wood, the slab is not produced a high number of times and the slab is produced due to strong bonding force with concrete There is a risk of damaging the appearance.

On the other hand, the plywood coated with the form panel is used, but the number of times it can be repeatedly used is limited, and thus a large amount of waste material is generated. In addition, since panels made of plywood do not transmit light, additional lighting equipment is indispensable for other work in the space below the mold.

However, since the stress on the load is weak when the wall is required to have rigidity compared with the slab, it is not suitable for the wall construction alone.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a slab- The present invention provides a wall mold that can be easily applied when a wall is required to have a stiffness compared to a wall.

In order to achieve the above object, the present invention provides a wall formwork comprising: a square frame formed of steel or aluminum; And a reinforcing rib which is provided at one side of the frame and is protruded in a lattice pattern on an opposed surface facing the frame and is formed so as to be rounded from the inside to the center of the frame, .

In this case, the frame may include: an outer frame constituting an outer frame; And a partition member installed inside the outer member to partition the inner space.

The partition member may include a plurality of vertical members spaced apart from each other along the left and right direction of the inner space of the outer member; And a horizontal member that vertically divides a space located on both sides of the space partitioned by the vertical member.

Further, the reinforcing ribs are independently formed in the plurality of compartment spaces.

Further, the projecting length of the reinforcing rib is proportional to the area of the compartment space.

The base panel is formed of a long fiber-reinforced thermoplastics (LFT) material, and the thermoplastic plastic is at least one selected from the group consisting of polypropylene (PP), polyamide (PA), and acrylonitrile-butadiene-styrene (ABS) The long fibers are characterized by being at least one selected from the group consisting of glass fibers, carbon fibers and natural fibers.

The composition ratio of the long fiber-reinforced thermoplastics (LFT) is 60 to 70% by weight of the thermoplastic resin and 30 to 40% by weight of the long fibers.

According to the present invention, it is possible to reduce the weight of the base panel, which is made of a synthetic resin material, so that it can be reused repeatedly, It is good in lightness, and installation work is unnecessary.

In particular, since a plurality of reinforcing ribs are protruded in a lattice pattern on opposite surfaces of a base panel that abuts a frame, it is advantageous that the reinforcing ribs can be easily applied to a wall construction requiring rigidity compared to a slab formwork.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals as in the drawings denote the same elements in the drawings, unless they are indicated on other drawings.

FIG. 1 is a perspective view of a wall mold according to the present invention, and FIG. 2 is an exploded perspective view of a wall mold according to the present invention.

1, a wall mold 1 according to a preferred embodiment of the present invention includes a rectangular frame 100 and a base panel 200 fixedly installed on one side of the frame 100 .

The configuration of the present invention will be described in detail as follows.

The frame 100 forms a main frame of the formwork 1 and is formed of steel or aluminum so as to reinforce the rigidity of the base panel 200 to be brought into contact with the concrete to be laid. Preferably, the frame 100 includes an outer frame 110 constituting an outer frame and a partitioning member 120 installed inside the outer frame 110 to form a plurality of inner spaces .

2, the partition member 120 includes a plurality of vertical members 121 arranged to divide the inner space of the outer member 110 in the left and right direction at a predetermined interval, a vertical member 121, And a horizontal member 123 separating one or more of the spaces partitioned by the upper and lower portions. In this case, an example in which the horizontal member 123 is provided on both sides of the outer frame member 110 will be shown and described in the present invention.

The base panel 200 is fixed to one side of the frame 100 via a fastening member (not shown). The base panel 200 is made of synthetic resin. That is, since the base panel 200 is formed of a synthetic resin material, the total weight of the dies 1 can be reduced. Particularly, since the base panel 200 is excellent in light-emitting property due to its material properties, there is no need for a separate lighting lamp, and there is an effect of facilitating demoulding after curing the poured concrete.

Preferably, the base panel 200 is formed of a long fiber reinforced thermoplastics (LFT) material and can be manufactured by compression molding using a mold or a press.

Preferably, the long fiber-reinforced thermoplastics (LFT) are produced by an LFT-D process. In this case, the thermoplastic plastic may be at least one selected from the group consisting of polypropylene (PP), polyamide (PA) and acrylonitrile-butadiene-styrene (ABS), and the long fiber may be at least one selected from the group consisting of glass fiber, Or more species.

For example, the composition ratio of the long fiber-reinforced thermoplastic resin (LFT) is preferably 60 to 70% by weight of the thermoplastic resin and 30 to 40% by weight of the long fiber.

The LFT-D process may be a long fiber reinforced thermoplastic-direct compounding (LFT-D) process of Dieffenbacher, Germany. This LFT-D process is economical and has the effect of minimizing the deterioration of the thermoplastic plastic, as compared with the long fiber-reinforced thermoplastic plastic produced by other processes, which can be continuously processed and each step is simplified.

3 and 4, a reinforcing rib 210 having a lattice pattern protrudes in a direction perpendicular to a surface of the base panel 200, which is in contact with the frame 100, do. Preferably, the reinforcing ribs 210 are independently formed in a plurality of compartment spaces formed by the partitioning members 120. The other surface of the base panel 200, which is in contact with the concrete to be laid, is formed as a flat surface, so that the surface abutting the base panel 200 when the concrete is cured forms a smooth flat surface.

The reinforcing rib 210 may be formed in such a manner that the reinforcing rib 210 is formed so as to be rounded from the inside of the compartment space of the frame 100 toward the center so as to maintain the rigidity and reduce the material cost. In other words, the reinforcing rib 210 of the grid pattern may protrude in a semicircular shape which is widely spread over the opposite surface of the partitioned base panel 200.

Referring to FIG. 5, the protruding length of the reinforcing ribs 210 is formed to be proportional to the area of the compartment space, thereby effectively reinforcing the rigidity of the base panel 200. 6, the reinforcing ribs 210 formed in the compartment space at the center of the frame 100, which is wider than the reinforcing ribs 210 formed in the compartment spaces on both sides of the narrow frame 100, As shown in Fig.

The wall formwork 1 according to the present invention having the above-described structure can reduce the weight of the base panel 200, which is made of a synthetic resin material, to be in contact with the concrete to be laid, It can be reused, and it is good in mining ability, so it is unnecessary to install a separate work or the like.

Particularly, since the plurality of reinforcing ribs 210 are protruded in a lattice pattern on the entire opposite surface of the base panel 200 contacting the frame 100, rigidity is required compared with the mold for a slab, It can be easily applied to the wall construction.

Further, the wall mold 1 is used in a basic size of 600 cm x 1,200 cm, and one side edge portion can be cut into a size of 300 cm x 1,200 cm when broken, and is usable.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
