Description

Raceway Formwork {FORM FOR WATER CHANNEL}

The present invention relates to a raceway, in particular, easy to install and dismantle, and to a formwork for the raceway can shorten the air.

In general, when cutting the ridge for road construction, etc., waterways are installed at both sides of the road or at the top of the incision to prevent the inflow of water into the incision or road through the mountain slope.

1 is a longitudinal sectional view of a formwork installed for conventional waterway construction.

As shown in Fig. 1, in order to install the raceway, first, the burrow is made in consideration of the depth and the width of the raceway, and the bottom slab 3 of the raceway is constructed, and when concrete is cured, the formwork is formed to form sidewalls of the raceway. Install (1). At this time, in order to prevent the formwork 1 from being deformed by the pressure generated at the time of placing concrete, a plurality of support trees 2 are installed inside and outside the formwork. Then, after the concrete 4 was cured, the mold 1 was demolded, and the filling material 5 mixed with crushed stone and cement fast was filled on the rear surface of the wall to construct a raceway.

However, the construction method as described above has a problem in that the construction period is long because the side slab is to be installed after the floor slab 3 is constructed. In addition, since a plurality of support wood (2) and the formwork (1) must be installed, it is difficult to install the formwork, and the filling material (5) has to fill the material between the channel and the ground has a problem. In addition, the incision is a steep inclination, there is a problem that the risk of a safety accident is doubled if a difficult construction for a long time in the steep slope.

In order to solve the above problems, an object of the present invention is to provide a waterway formwork that is easy to install and dismantle the formwork, and can shorten the construction period.

Unlike the conventional formwork for the raceway according to the present invention is to install a waterway by installing only the inner formwork of the raceway in the waterway to the gulto do not install the formwork outside the raceway, as shown in Figure 2 110, side plates 120 and 130 connected to hinges 180 at both sides of the bottom plate 110, vertical fixing members 150 for fixing the bottom plate 110 and the side plates 120 and 130, It is made of a horizontal fixing member 140, described in detail as follows.

The bottom plate 110 is a plate having a rectangular shape as shown in Figure 2, the plate is formed with a plurality of first fixing holes 111 (see Figure 5) for coupling with the vertical fixing member.

The side plates 120 and 130 are rectangular plate materials similar to the bottom plate, and the lower sides of the side plates 120 and 130 are coupled to the hinge 180 by the left and right sides of the bottom plate 110 (see FIG. 3). In addition, a plurality of second fixing holes 131 (see FIG. 6) for coupling with the horizontal fixing member are formed. Meanwhile, the bottom plate 110 and the side plates 120 and 130 are formed with stepped portions 160 having a plurality of protrusion holes 161 (see FIG. 2) at the front end side in order to be connected to other formwork. A plurality of fixing protrusions 162 are formed at the rear end side (see FIGS. 2 and 6).

As shown in FIG. 5, the vertical fixing member 150 has a screw line formed on an outer circumferential surface thereof and is screwed into the first fixing hole 111 of the bottom plate 110, and one end penetrates through the bottom plate 110. It protrudes to the floor and is installed to close to the ground. A plurality of first regulation holes 151 are formed at the other end of the vertical fixing member 150, and the first regulation holes 151 are formed in an elliptical shape and elongate in the longitudinal direction of the vertical fixing member 150. Then, the nut 156 is extrapolated to one end of the vertical fixing member 150 before the vertical fixing member 150 is coupled to the bottom plate 110, one end of the vertical fixing member 150 from the bottom plate 110 When protruded and closed on the floor, the nut 156 moves to contact the bottom plate 110 and is installed.

As shown in FIG. 6, the horizontal fixing member 140 includes a tubular body 145 and first and second horizontal fixing bolts 141 interpolated from both sides of the tubular body 145. 6 shows that one side of the horizontal fixing member 140 is coupled to the side plate 130 as shown, and the coupling structure on the right side is the same as the left side, and is omitted. One end of the first horizontal fixing bolt 141 and the other end of the second horizontal fixing bolt is formed with a screw line on the outer circumferential surface is screwed into the second fixing hole 131 of the side plates (120, 130) is installed protruding to the left and right ground. . The other end of the first horizontal fixing bolt 141 and one end of the second horizontal fixing bolt are inserted into the left and right sides of the tubular body 145 and screwed together, and the tubular 145 has a vertical fixing member 150 with the bolt 170 and A second restriction hole 144 is formed to be fixed by the nut 171 (see Fig. 7). Meanwhile, a plurality of pin holes 142 may be inserted into the first and second horizontal fixing bolts so that the first and second horizontal fixing bolts 141 can be easily inserted into the second fixing holes 131 by inserting pins 142. Formed. The nut 146 is extrapolated to one end of the horizontal fixing member 150 before the horizontal fixing member 140 is coupled to the side plates (120, 130), the horizontal fixing member 150 protrudes from the side plate 110 to the left and right ground When closed, the nut 1146 is installed to move in contact with the side plates (120, 130).

Meanwhile, one end of the vertical fixing member 150 protruding from the side plates 120 and 130 and the bottom plate 110, one end of the first horizontal fixing bolt 141, and the other end of the second horizontal fixing bolt are elastic. Corrugated pipes 149 and 159 are extrapolated and installed. The corrugated pipes 149 and 159 are for allowing the protruding portions of the vertical and horizontal fixing members 140 and 150 to withdraw the vertical and horizontal fixing members 140 and 150 even when the concrete is cured.

Hereinafter, the installation operation of the raceway formwork according to the present invention with reference to FIGS.

First, after finishing the pit work, the left and right and bottom grounds are arranged, and the vertical fixing member 150 is inserted into the first fixing hole 111 of the bottom plate 110, and the corrugated pipe 159 is installed at the protruding portion ( 8). The nut 156 is moved to contact the bottom plate 110. Then, the horizontal fixing member 140 in which the first and second fixing bolts 141 are inserted in both sides of the tubular body 145 is inserted into the second fixing hole 131, and the corrugated pipe 149 is installed at the protruding portion. Then, the nut 146 is moved to contact the side plates (120, 130). Thereafter, the bolt 170 is inserted into the second regulation hole 144 formed in the tubular body 145 of the horizontal fixing member 140 and the first regulation hole 151 of the vertical fixing member 150, and the nut 171 is inserted into the nut 171. It is fixed to combine the vertical and horizontal fixing members (140, 150). This is to prevent the floor plate 110 rises when the concrete is poured (see Figs. 7 and 8). Then, the bottom step of the mold 160, the projection hole 161 is placed so as to be extrapolated to the fixing projections 162 of the bottom plate 110 is installed, and then fixed with a nut 163 (see Figs. 4 and 9). ).

As described above, the formwork for the raceway according to the present invention is installed only the inner formwork consisting of the bottom plate 110 and the side plates (120, 130) without installing the outer formwork, vertical and horizontal fixing members 140, 150) to prevent deformation of the formwork, to provide a space in which concrete can be poured, and to facilitate the connection with other formwork by installing a projection hole 161 and a fixing projection 162.

As described above, the present invention is installed only the formwork consisting of the bottom plate 110 and the side plates (120, 130), by using the vertical and horizontal fixing members 140, 150 to prevent deformation of the formwork, installation and disassembly of the formwork It is easy and the construction period can be shortened.
