Description

Formwork and connecting device for drainage pipe connection

The present invention relates to a formwork and a connection device for concrete fume pipes widely used for drainage pipes, in particular, to a drainage pipe formwork and a connection device that provides a completely leak-proof connection while deforming to the curved state of the drainage pipe on the construction topography.

In general, concrete fume pipes, PE reinforcement spiral pipes, etc., which are widely used in civil engineering work, are hard products, so sections of bending drainage pipes are often formed according to the conditions of the construction site. When the parts are connected after the separate processing, but there is a problem in the robustness, etc. The present invention is described as follows according to the drawings as the invention is configured to give back after curing for a certain period of time by inserting a reinforcing agent such as cement mortar.

As shown in Figures 1, 2, and 3 in the connection portion of the drainage pipe (1) in the soft inner wall (7) formed by spiral winding with a soft synthetic resin material that retains the flexibility when bent in accordance with the conditions of the construction section in the basement Both sides form an assembly table (3) for inserting and assembling into the connection part of the drainage pipe, but the curved part is composed of a spiral winding soft resin and a hard resin, respectively, to form a fusion point (4) by the corrugated support (5). Corrugated support (5) formed by winding spirally to provide flexibility while forming the thickness of main drainage pipe (1), that is, the input space of cement mortar (10), intermittently integrated with the soft inner wall (7). In between the soft formwork (6) is composed integrally at this time, the hard resin (11) is composed of a four-winding winding, so it is composed of the corrugated support (5) and the fusion point (4) and the assembly table (3) part of the drainage The tube (9) is kept in a circular state for easy assembly The. Here, as shown in FIG. 9, the cement mortar 10 is filled by filling the cement mortar 10 in the filling space A with the cement mortar inlet 2 of the present invention assembled by bending between the drainage pipes 9. The direction is integrated with each other in the space of the soft formwork 6, and in the longitudinal direction is integrated with each other in the space between the fusion point 4 of the corrugated support 5, the cement mortar cured in the input space (a) is In the connection device of the present invention, the invention provides the product of the present invention even if it is provided with a corrugated support (5 ') formed by a soft resin.

And as shown in Figure 2 (b) is to make the assembly rib (3 ') to compensate for the leakage of the assembly (3) when inserting a waterproof filler (cement mortar or hard foam waterproofing agent).

In this case, if flexible bars 6 'and 7' are formed on the soft inner wall 7 and the soft formwork 6 as shown in FIG. 4, the workability is more convenient in the field of construction. Done.

As an embodiment of the present invention, as shown in Figures 5, 6, 7, the cement mortar input space (a) between the soft inner wall (7) and the soft formwork (6) may be integrated with a hard support (8) or the soft formwork ( The cross section of the outline of 6) is invention which may be comprised linearly in the longitudinal direction. At this time, the assembly support (3) portion of the hard support (8) is appropriately removed in the production process to facilitate the connection of the drainage pipe (9).

In another embodiment of the present invention, as shown in Fig. 9 (a) (b) (c) by reducing the number of spiral windings of the fusion point (4) of the corrugated support (5) 1 to 2 inlet 2 It is a product used as a connecting device in the straight state of the drainage pipe (9) by the formation.

And as a product derived from the present invention as shown in Figure 10, 11, 12, such as the fume pipe in the drain pipe, if the weight is heavy or large size of the construction is not easy to move to the drain pipe to be constructed as a drain pipe A product capable of narrowing the length of the connection formwork of the invention to the drainage pipe in the longitudinal direction is required, as shown in Fig. 11 (b) (b) to form an uneven portion with a cross-sectional structure in the connection formwork body 1 '. If the uneven inner pipe 12 and the uneven mounting table 13 is formed in the assembly table 3, the connection formwork 1 and the drainage pipe 9 of the present invention at the construction site of the drain pipe which is dug when the underground is buried. The assembly of the connection part is easily provided, and when it is filled by inserting the rigid synthetic resin foam (10 ') into the inlet (2 "), it provides a complete leakage prevention effect, and especially when the longitudinal direction is narrowed, the outer diameter of the asperity assembly stand (13) transform It also provides an external leakage blocking effect of the mortar (10) In addition to the application example of the present invention as shown in Figs. ) Is often used as a product, the through hole 26 is formed on one side of the connecting device of the present invention, the assembly table 23 is formed on one side and cement mortar inlet 22 on the other side fusion welding with the corrugated support 25 After the point 24 is composed of spiral windings alternately and the cement mortar 10 at the end is easily assembled into the inner space (a), the branch connecting device constituting the partition wall 30 is assembled with the joining table 31. It is a water-invented invention to be filled and used in the inner space (A) with cement mortar 10. Also, the cross-section of the product has a concave-convex structure so that the branch connection device is provided with some flexibility depending on the construction site. Provided inner tube 32 and outer tube 33 Therefore, when the construction of the elbow or the curved part of the construction site at the construction site, the present invention is firm and secured to prevent the leakage of sewage, and provides semi-permanent use and no bending angle. This product is used as a connection device for straight state construction.

The present invention relates to a formwork and a connecting device for connecting drainage pipes, and particularly, to solve external pressure reinforcement and prevent complete leakage while properly adjusting regardless of the bending angle at a curved site such as concrete fume pipes, PE reinforcement spiral pipes, and other drainage pipes. In addition, the direction of the drainage pipe is not only straight, but also to form a concave-convex structure in the connecting formwork 1 'of the present invention to facilitate the assembly of the drainage pipe.
