Description

{Mold for pillar}

The present invention relates to a mold apparatus for a column, and more particularly, to a method for securing safety by using a column form of a unit unit having a reinforcing structure, The present invention relates to a mold apparatus for a column.

In general, the column formwork is used for forming a pouring space for constructing a square column of a concrete structure. Such a column formwork mainly uses a wood panel as a frame, but since a lateral pressure is strongly generated when a concrete is laid, The use of panels as frames has also been proposed and used, and combinations thereof have also been proposed.

That is, a wooden or metal panel is woven with a square frame to form a column form, and consequently, a concrete is placed in a built-in space formed therein to construct a square column of a concrete structure. And is used for preventing the casting of the column form during the process of casting concrete to form the column.

The concrete pillar installed in the inner space should be maintained in a certain shape until the curing process of the concrete poured in the inner space is completed.

Meanwhile, since the conventional concrete column can be designed variously according to the size and size of the concrete building, as well as the construction method and the like, the size of the concrete column including the area of the column can be changed.

Therefore, in order to construct the column, it was necessary to manufacture the column form according to the size of the column by referring to the design diagram. The construction of the column form is often performed directly by the operator in the field, The use of prefabricated column formwork according to the design may lead to an increase in manufacturing cost.

In particular, since the reinforcement structure having rigidity against the lateral pressure transferred from concrete is insufficient, basic safety of the column form can not be secured.

The molding apparatus for a column according to the present invention comprises a plurality of column molds (10) which are mutually fastened along the shape of a column mounting surface and fastening means (20) for fastening and fixing the column molds .

As shown in FIG. 1, the column mold 10 can be manufactured as a single unit module. The column mold 100 has a square plate 100 and reinforces rigidity against lateral pressure transferred from the concrete, And a plurality of frames connected at the back surface of the plate member 100 in order to facilitate the operation.

For example, the plurality of frames may include a reinforcing frame 110 connected to a rear surface of the plate member 100 along its rim, and an auxiliary frame 120 connecting the reinforcing frame 110 in a lateral direction and a longitudinal direction Lt; / RTI >

At this time, the reinforcing frame 110 and the auxiliary frames 120 are preferably formed in the shape of a pipe having an internal space to reinforce the rigidity.

In the present invention, at least four or more of the column molds 10 are mutually fastened to each other to form a mold with respect to the column construction surface. Even if the column molds 10 are not separately manufactured, A mold capable of flexibly coping with the size change of the column mounting surface can be constituted by the fastening structure.

More specifically, four or more column molds 10 constituted by the unit modules are disposed on the side surface of the reinforcing frame 110 of the other column mold 10 adjacent to the front surface of the plate member 100 of one column mold 10 And can be fastened and fixed through the fastening means 20.

Referring to FIG. 1, an auxiliary frame 120 according to an exemplary embodiment of the present invention includes a reinforcing frame 120 having a lattice shape at a center of the back surface of the plate member 100, A plurality of vertical frames 122 connected to the reinforcing frame 110 in the vertical direction at upper and lower portions of the grid frame 121 and a plurality of vertical frames 122 connected to the grid frame 121, And a horizontal frame 123 connected to the reinforcing frame 110 in a horizontal direction in a boundary area between the vertical frame 122 and the vertical frame 122.

In this case, the horizontal frame 123 provides a fastening space 124 for the fastening means 20, and can be manufactured in a rail structure so that the fastening pin 210 described below can be slid. For example, the horizontal frame 123 may be provided with a fastening space having a rail structure by opening the central portion in front of the horizontal frame 123 along the longitudinal direction as shown in Fig.

The horizontal frame 123 of the present embodiment has a plurality of through holes 125 communicating with the fastening space 124 through the plate member 100 at regular intervals so that the through holes 125, Side holes 111 communicating with the other side of the fastening space 124 may be formed on a side surface of the reinforcing frame 110 that faces each other.

That is, a plurality of through holes 125 are formed at one side of the fastening space 124 of the horizontal frame 123, and one side hole 111 is formed at the other side surface of the fastening space 124 .

The fastening means 20 according to the present embodiment fixes the fastening pins 200 passing through from the other pillar form 10 facing and the fastening pins 200 penetrated as shown in FIGS. 3A and 3B And a fixing pin 210 for fixing the cross column form 10 to each other.

The fastening pin 200 has a tapered fin portion 201 and a fastening plate 202 connected to the other end of the fin portion 201 having a width that is relatively larger than the diameter of the side hole 111. [ And a cutout portion 203 cut in the longitudinal direction at the fin portion 201.

2 and 4, the fastening pin 200 has a through hole 125 formed in the other pillar form 10, which faces the side hole 111 of the single pillar form 10, The hooking plate 202 can not completely pass through the side holes 111 of the one pillar form 10 and only the pin portions 201 penetrate the through holes 125 of the other pillar form 10. [ And the cut portion 203 in the longitudinal direction together with the fin portion 201 can be exposed in the fastening space 124. [

5A and 5B, the fastening pins 200 are configured to pass through a selected one of the through holes 125 of the other column formwork 10 according to the size of the column construction surface. As shown in FIGS. 5A and 5B, By selecting one through-hole 125 in the hole 125, the size of the column die can be changed.

The fixing pin 210 includes an insertion portion 211 having a shape in which the width of the fixing pin 210 is relatively narrowed toward the through hole 125 on the fastening space 124 of the horizontal frame 123, The position of the fastening pin 200 is fixed by being inserted into the cutout 203 of the fastening pin 200 protruding from the fastening space 124 through the through hole 125 of the column mold 10. [

In this case, the fixing pin 210 has a structure in which the width of the fixing pin 210 gradually increases toward the opposite direction of the through hole 125, so that the fixing pin 210 is gradually inserted into the cut- Since it acts as a force for pulling the fastening pin 200 toward the fastening space 124 side, it is possible to improve the fixing force and improve the adhesion with the other pillar form 10 facing each other.

As described above, the fastening means 20 of the present embodiment can simplify the disassembly process as well as the assembling between the molds, and it is unnecessary to use a separate tool, so that the noise can be minimized and the convenience of the work can be improved .

4 and FIG. 3B illustrate an application example of the fixing pin 210 and a structure in which the fixing pin 210 slides on the coupling space 124. As shown in FIGS. 4 and 3B, the fixing pin 210 Is coupled to the inserting portion 211 in a direction perpendicular to the inserting portion 211 and has a width corresponding to the width of the engaging space 124 so as to slide along the rails of the engaging space 124. [ A pair of guide protrusions 212 and a handle 213 protruding and extending outward from the opening of the coupling space 124 between the pair of guide protrusions 212.

The fixing pin 210 having such a structure can be slid on the locking space 124 with the guide protrusion 212 corresponding to the width of the locking space 124, So that a predetermined position can be maintained so as to face the cutout 203. In addition, since the handle 213 is protruded to the outside of the engaging space 124, the operator can easily grasp the handle to move the fixing pin 210.

Here, since the column mold 10 is usually stacked for transportation and mounted on a vehicle or the like, the fixing pin 210 may serve as an unnecessary element for loading due to the protruding structure.

According to the present embodiment, the horizontal frame 123 has an opening 126 opened at a width corresponding to the width of each guide protrusion 212 of the fixing pin 210 and communicating with the engaging space 124 So that the fixing pin 210 can be received in the engaging space 124 or separated from the engaging space 124 through the opening 126.

Meanwhile, the column formwork 10 of the present invention provides a structure that can be varied in correspondence with the shape and size of the column construction surface. In the case of the column construction, in which the maximum construction space can be formed by only the four column formwork 10 The unit column formers 10 constituting the frame of each face can be extended so that at least two or more of them are coupled in parallel.

6, a plurality of fastening holes 112 are formed in the upper, lower and both side portions of the reinforcing frame 110 of the column mold 10 so as to penetrate the sides of the reinforcing frame 110, Or the bolts 30 are combined with the fastening holes 112 of the other column form 10 adjacent to the left and right sides to constitute one unit column form 10 which is expanded.
In this way, even if a relatively large column construction is designed, the column formwork according to the present invention can be expanded by connecting the column formworks 10 without a separate manufacturing process, .

In addition, the column mold apparatus according to the present embodiment may further include additional components for solving all the problems that may occur in the expansion function through connection between the column molds 10. [

For example, the column mold 10 has a structure for opposing the side pressure as described above, and the reinforcing frame 110 may be formed in the shape of a pipe having the internal space 113, The compression force toward the internal space 113 is applied to the fastening hole 112 formed on the inner space 113 by the bolt 30 coupling.

In this case, since the fastening hole 112 communicates with the internal space 113, a separate reinforcement structure for supporting the fastening hole 112 from the compressive force is not provided. Therefore, And the reinforcing frame 110 is detached from the plate member 100 in a repeated deformation process. As a result, the safety of the column molding apparatus can not be ensured .

In the present embodiment, the reinforcing frame 110 is formed of a rectangular tube having an inner space 113, and the reinforcing frame 110 is formed in the inner space 113, And a cylindrical airtight bushing 114 configured to enclose the coupling hole 112 in the coupling hole 113 and seal the communication area between the coupling hole 112 and the inner space 113. [
7 and 8, the airtight bushing 114 may have a hollow pipe shape and may be interposed in an internal space 113 between one surface and the other surface of each tube of the reinforcing frame 110, One or more fastening holes 112 may be formed on one surface and the other surface of each pipe so that the rim of the fastening hole 112 may be extended to be fitted in the hollow of the hermetic bushing 114.

The airtight bushing 114 is disposed in the inner space 113 in a direction opposite to the compressive force generated by the bolt 30 coupling between the column molds 10, Non-metallic materials may be applied.

The airtight bushing 114 is configured to seal a portion communicating with the internal space 113 as well as a function to reinforce a portion of the fastening hole 112 that is relatively weak in accordance with the bolt 30 connection, So that it is possible to prevent corrosion or the like from penetrating into the inside of the frame 110.

Also, in this embodiment, the separation space 115 may be formed in the reinforcing frame 110 as a means for separating the column molds 10 interconnected in the process of disassembling the column mold 10 after concrete curing more easily have.

That is, as shown in FIG. 9, a part of the reinforcing frame 110 of the column mold 10 facing each other may be partially bent outward to form the separation space 115.

In general, during the curing process of the concrete, the column molds 10 connected to each other can be fixed to the column surface by the adhesive component of the concrete. Accordingly, in this embodiment, by forming a clearance between the reinforcing frames 110 in which the tightly connected state is maintained by the separation space 115, a tool such as an oblique (par) tool which can utilize the principle of the lever So that the column form 10 fixed to the column surface can be easily separated.

9 shows an example in which the separation space 115 is formed in both the reinforcing frames 110 facing each other. However, the present invention is not limited thereto, and the reinforcing frame 110 selected from among the reinforcing frames 110 facing each other may be used. The separation space 115 may be formed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
