Description

Connecting device and formwork for flexible reinforced drainage pipes {.}

The present invention relates to a connection device and formwork for Magokseong reinforced reinforcement drainage pipes configured to be suitable for the conditions to bend in accordance with the terrain of the construction site, especially in large diameter drainage pipes.

Conventionally, when the direct diameter of the standard is large diameter of Ø1200m / m or more, the curved part of the drainage pipe or the case of the larger standard is made of concrete reinforcement in the box (Box). After assembling formwork and adding cement mortar, the work was done in order of curing and removing formwork, which required a lot of inefficient air.

In the present invention, in the drainage pipe for cement mortar input, the flexible beam coupling bar is formed in the middle part or intermittently by spiral winding, but the drainage pipe is coupled to the coupling bar 14, but the cement mortar is injected into the inlet. To provide a robust connection and formwork for drainage pipes.

The present invention is a product related to the connection device and formwork for the drainage reinforcing pipe for curved reinforcement, and the improved product of another structure for the applicant's selection applications Nos. 98-17709 and 98-22637, and according to the design and terrain in the construction site In the case of changing the direction by bending the bureaucracy conventionally used to decorate the drainage pipe by a separate elbow or forced bar bar The present invention is an invention configured to bend and use the drainage pipe itself as described in detail with reference to Figure 1 As shown in Fig. 2, the inner side 13 and the outer side 15 are integrated in a spiral winding circuit 14 times with the spiral winding coupler 14 at the center to provide a tightness and reinforce the flexibility. Both sides are used by joining the drainage pipe 20 by forming a junction portion 12 and used to bend in accordance with the topography of the construction site as shown in FIG. The invention is configured to fill the cement mortar 17 in the inner space of the inner and outer surfaces 14, 15 by curing the inlet 16 on one side as shown in Figures 3 and 4 to cure for a certain time to be.

6, 7, 8 (a) as shown in Figure 1 in order to reinforce the durability of the outer surface 15 in FIG. If necessary, the outer wall surface 21 is configured here.

In the embodiment of Fig. 3, as shown in Figs. 8 (b) (c) (d) (e) and (b), the soft waterproof sheet stand 30 is integrated with the reinforcing spiral band 19 of the outer wall surface 21. By forming the assembly sphere 33 and inserting the air contact shrinking tube 31 or the heat shrinking bend 31 'along the spiral groove, the soft waterproof sheet stand 30 with the tightening iron core 32, the present invention Tighten the connecting part of the drainage pipe 20 assembled in the connection device of the shrinkage and harden as it shrinks after a certain time and prevents leakage.In the case of using the heat shrink tube 31 ', tightening it in an appropriate manner and then heating it softly to shrink. It is a product to tighten the waterproof seat 30.

In this case, the protective wall 23 is integrally wrapped on the outer surface 15 of the connecting device 11 to reinforce the durability of the coupling unit 14 so that the durability of the connecting device is reinforced while maintaining flexibility.

In addition, in the large diameter of the connecting device 11, the cross section of the joint 12 must be maintained in a circular shape so that the drainage pipe 20 can be easily inserted into the outer surface 15 so that the reinforcing holes 19 are spiral wound integrally. In order to further reinforce this, the outer wall surface 21 is integrally wrapped on the outer surface of the reinforcement 19, and in order to facilitate the drainage pipe insertion process, as shown in FIGS. Form joints 13 'on both sides.

And when the cement mortar (17) input in the connection device or the leakage of the cement mortar (17) in the connection device 11 that does not normally use the cement mortar 17 and the inserted drainage pipe 20 of the joint 12 It is easy to block the leakage between the assembly intervals, as shown in Figures 9, 10, 11 inserts the belt 25 is composed of the resilient 26, 26 (26).

In Embodiment 1 of the present invention, as shown in FIG. 12, the height (H) and the width (P) of the reinforcing tool 30 in the spiral tube in which the reinforcing bar in which the conventional reinforcing tool 30 is formed is integrated with the spiral winding. Compared to the conventional standard, 1.5 times larger than the same, but the cement mortar inlet 16 formed on one side in the lengthwise direction for the drainage pipe formwork given the height and width than the conventional reinforcement 30, respectively 1.5 times or more It is an invention for providing as a formwork for drainage pipes by using as a cement mortar 17 input space (30 '). At this time, as shown in Figure 13 (c) to the outer wall surface 18, which retains flexibility, the fixing portion 14 is reinforced.

In addition, in the description of the second embodiment of the present invention, as shown in FIGS. 14 and 1516, the corrugated support 28 and the melting point 27 are integrated between the inner surface 13 and the outer surface 18. The invention relates to a conventional drainage pipe formwork with a cement mortar inlet 16 on one side, and to a plurality of drainage pipe formwork providing intermittent reinforcement by rotating the coupler 14 intermittently in a spiral winding several times in the longitudinal direction.

The present invention provides construction properties and economics when moving the direction of the drainage pipe in the construction site by providing the connection device and formwork for the flexible reinforcement drainage pipe, and in particular, provides an economical product by providing durability, such as ground subsidence, earth pressure, lubricity, etc. It is a useful invention.
