The present invention relates to a product of a structural improvement for a draft application (20-2000-12938) as a product related to a formwork for drainage pipes for curved reinforcement.

In general, when the direction of the drainage pipe is converted to change the direction according to the design and terrain at the construction site, a conventional elbow or forcing the drainage pipe to be used bar bar bar according to the present invention. The conventional spiral tube which forms a constant equal interval between the hollow balls 42 and the spiral windings in (13) has too little constitution of the hollow balls 42 and there is no input space for the cement mortar 17. In the soft ground where the external pressure reinforcement is too weak to operate a lot of external pressure, there are many problems to be used stably. As shown in FIG. 1 and FIG. The reinforcing hole 39 which enlarges the height H and the width P which provide an area of 1.5 times or more of the height h and the width p of the hollow sphere 42 formed in the conventional spiral tube, respectively. However, the invention provides a formwork 11 that can be used by filling the cement mortar 17 in the reinforcement 39 and the image of the reinforcement 39 is easy at the construction site of the formwork 11 of the present invention. On one side of the side there is provided a product that constitutes the mortar 17 inlet 16. In the present invention, in the case of bending the drainage pipe according to the design and construction conditions in the construction site, there is a problem in that conventionally using a separate elbow-like connection pipe bar in the present invention in order to bend the formwork 11 in FIG. As shown, after bending the inner surface 13 of the reinforcing hole 39 to the flexible groove 35 at the curved portion, construct the form 11 along the drainage pipe, and then drain the water 17 into the inlet 16. Fill the mortar 17 in the inner space of the reinforcement 39 to cure for a certain period of time, then back to the more dug soil around the earth to be buried underground.

Another structure of the flexible recess 35 for bending on the inner surface 13 in the present invention is to reinforce the flexible recess 35 to the inclined reinforcement 34 and the joint 14 'as shown in FIG. It is a product provision integrated in the upper side of (39).

In addition, the reinforcement as shown in Figure 6 in order to provide external pressure reinforcement for long-term stable use by damage or construction of the product according to the bad conditions of the construction site used by buried formwork 11 provided in the present invention In accordance with the upper side of the (39), the protective wall 23 is extrapolated integrally, but the inclined flexible stand 34 'and the coupling table 14 are integrally formed on the inner side surface 13 with the inclined flexible stand 34'. The invention for providing a product that is configured and reinforced.

In order to further reinforce the flexibility and the external pressure reinforcement in the above-described product, as shown in FIG. 7, the reinforcing ribs 38 are formed on both side wall surfaces of the reinforcement 39, and the outer wall surface 23 is bent. It is supported by the molded inclined groove 34 'to be structurally reinforced and to form a flexible groove 37 at the bent portion of the inner surface 13 to provide a flexible and external pressure reinforcement product.

At this time, the flexible groove 37 by bending the inner surface 13 by the inclined flexible frame 34 and the junction 14 as shown in Fig. More reinforced products are provided.

And the description of the embodiment of the present invention as shown in Figure 9 constitutes an intermediate layer surface 40 between the inner surface 13 and the protective wall 23, the reinforcement 39 (39 ') is a two-layer structure The inner surface 13 and the protective wall 23 are alternately bent at the curved portion to be curved in the spiral tube reinforced by the inclined flexible bar 34 'and the coupling table 14 on the inner surface 13, When the intermediate side 40 is bent into the reinforcing support 41 'and fixed to the protective wall 23 by the coupling table 14, the intermediate layer 40 is bent into the reinforcing support 41' to provide the support role. Structural reinforcement provides flexibility and robustness to external pressure reinforcement.

Here, in the description of the present invention, the curved device of the present invention shown at a predetermined interval as shown in Figure 10 mortar filling space formed by bending the inner surface 13 and the outer surface 15 of the curved portion ( 12, the protective wall 23 is configured to be inserted into the filling space 12 in the mortar inlet 16 in the longitudinal direction to assemble the formwork 11 of the present invention according to the drainage pipe at the construction site and cement mortar (16) Filling the filling space through the inlet 16 is an invention configured to give a certain time to cure. In this case, the filling space 12 of the drainage pipe 11 between the curved reinforcement portion at the inner side 13 and the outer side 15 as shown in FIGS. 11 and 12 to provide the firmness of the filling space 12. Reinforced by the corrugated support 28 and the fusion point 27 in the cement mortar inlet 16 on one side of the product in the construction site in the curved state according to the design or construction conditions in the construction site and shown in Figure 13 It is an invention configured to be used by filling with mortar as cement.

The present invention provides the formability for the flexible reinforcement drainage pipes, when the construction site moves in the direction of the drainage pipes, as well as the connecting portion as well as the curved role of the flexible reinforcement formed intermittently in the drainage pipes, the workability and economic efficiency are provided, and in particular, the civil engineering work in a bad condition The formwork of the present invention, which is provided by reinforcing synthetic spiral pipes in the field, is simply a cement mortar, which is a useful product that provides workability and economy by providing a rigid and external pressure-reinforced drainage pipe such as a concrete fume pipe.
