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

1 and 2, the apparatus for installing a socket formwork of the present invention comprises an outer bolt 210 passing through a square pipe 200 and an inner bolt 220. The outer bolt 210 and the inner bolt And the bolt 220 supports the outer mold 110 and the inner mold 120.

First, the present invention is based on the provision of a pair of outer formwork 110 and a pair of inner formwork 120 for installing a base part of a sidewall and both sidewalls.

At this time, the outer formwork 110 and the inner formwork 120 are generally used as a formwork, and they are formed of a rectangular base plate, a flange provided on the four sides of the base plate, and a plywood attached to the base plate 4). Further, the base plate may be a normal flat plate or a shape in which the middle portion is omitted.

As shown in FIGS. 1 and 2, the apparatus for installing a lateral formwork of the present invention is composed of a square pipe 200, an outer bolt 210, and an inner bolt 220, and its structure is very simple, .

The square pipe 200 is for supporting the outer mold 110 and the inner mold 120 and is positioned above the outer mold 110 and the inner mold 120. The square pipe 200 can be a circular or hexagonal pipe, but it is most easily obtainable, and it is advantageous that the rectangular pipe 200 is not rolled when it is placed on the upper side of the formwork.

The pair of outer bolts 210 are provided so as to penetrate both side ends of the square pipe 200 to support the outer mold 110 positioned at both ends of the square pipe 200.

The pair of inner bolts 220 are also installed through the square pipe 200.

At this time, the inner bolt 220 is installed to be spaced inward from the outer bolt 210 to support the inner mold 120 located inside the outer mold 110.

That is, the outer bolt 210 supports the upper side of the outer mold 110 and the inner bolt 220 supports the upper side of the inner mold 120, that is, the inner and outer molds 120, < / RTI > 110).

The outer bolt 210 is composed of a butterfly nut 211 provided on the upper side and a protruding step 212 provided on the lower side so that the rectangular pipe 200 and the outer mold 110 are coupled to each other. The protruding protrusion 212 of the outer bolt 210 is hooked on the lower side of the outer mold 110, that is, the lower portion of the flange, and the outer mold 110 is pulled toward the square pipe 200 by tightening the wrench nut 211, So that the form 110 is firmly fixed to the square pipe 200.

At this time, the protrusion 212 is formed by welding one side of the 'A' -shaped angle to the side of the outer bolt 210 by welding or the like, and a cutout 213 is formed in the middle of the protrusion 212 So that the flange of the outer mold 110 can be inserted. The cutout 213 allows the flanges of the two outer molds 110 to be inserted together at the locations where the two outer molds 110 are in contact so that one protruding ridge 212 is positioned between the two adjacent outer moldings 110 Can be fixed together.

This outer bolt 210 places the protrusion 212 in the lower flange of the outer formwork 110 and then tightens the butterfly nut 211 so that the outer formwork 110 can be fixed very quickly and conveniently .

A nut 222 which is capable of locking or unlocking the inner bolt 220 is welded on the upper side of the square pipe 200, And an inner die support member 223 connected to the inner die 120 is provided on the lower side of the inner bolt 220.

The inner mold support member 223 includes a rectangular frame 224 having a space into which the lower end of the inner bolt 220 is inserted and can be rotated and flowed, 120). ≪ / RTI > The rectangular frame 224 may have a rectangular shape or a trapezoidal shape in which the thickness of the outer side portion is made thicker. This trapezoidal shape further presses the outer portion of the inner mold 120 to prevent the inner mold 120 from deviating outwardly. And may have an outer protruding protrusion 228 as described below.

Here, the inner bolt 220 compresses and supports the upper side of the inner mold 120 by tightening the handle 221.

The inner bolt 220 may include a through hole formed in a lower end portion thereof and a pin 227 inserted into the through hole so that the inner bolt 220 does not separate from the rectangular frame 224. The rectangular frame 224 is fixed to the inner bolt 220 by inserting the pin 227 after inserting the inner bolt 220 into the hole on the upper side of the rectangular frame 224. [ When separating the two components, the pin 227 of the inner bolt 220 is easily removed. The inner bolt 220 can be separated from the square pipe 200 and the outer bolt 210 can be separated from the square pipe 200 by removing the butterfly nut 211 first. That is, in the present invention, when a plurality of bolt holes are formed on the square pipe 200 and the nut 222 is coupled to the square pipe 200 at a position where the inner bolt 220 is to be installed by welding or the like, The inner bolt 220 and the outer bolt 210 are arranged to move in accordance with the width of the sidewall of the sphere.

The inner mold support member 223 includes an outer protruding protrusion 228 on the other side of the inner protrusion protrusion 225 to support the outer side of the inner mold protrusion 120 while being smaller than the inner protrusion protrusion 225, Thereby enhancing the supporting force with the supporting member 120. The outer protruding jaw 228 can prevent the inner mold 120 from deviating outwardly. However, if the outer protruding protrusion 228 is too large, it is preferable to protrude the inner protrusion 120 so that the inner protruding protrusion 120 does not come off because it is an obstacle to adjust the inner protruding protrusion 120 to a required angle.

As described above, the present invention is for installing a pair of outer molds 110 and a pair of inner molds 120 for constructing the base portion and both sidewalls of the sphere, A pair of outer bolts 210 installed to penetrate both side ends of the square pipe 200 and a pair of inner bolts 210 spaced inward from the outer bolt 210 and passing through the square pipe 200, The outer bolt 210 supports the upper side of the outer formwork 110 and the inner bolt 220 supports the upper side of the inner formwork 120 and supports the outer formwork 110 when the side formwork is constructed. The inner mold 120 can be supported very quickly and efficiently to improve the working efficiency and to adjust the joining position of the outer mold 110 and the inner mold 120 according to the construction conditions, .

4, the outer mold 110 and the inner mold 120 are formed of a rectangular base plate, a flange provided on the four sides of the base plate, and a plywood attached to the base plate. The base plate may be a normal flat plate or a shape in which the middle portion is omitted.
