Description

Formwork for connecting heterogeneous drainage pipes {omitted}

The present invention often reduces or enlarges the dimensions (size) of the drainage pipe (9) according to the construction section of the concrete fume pipe and the drainage pipe which are widely used for the drainage pipe bar. As an invention, the fixed wall 6 is formed on one side of the connection device A of the present invention, but the mortar inlet 7 'is formed on the inner side in the circumferential direction, so that the separate connection device B is inserted into the inner side. The mortar 10 insertion hole 8 is formed on the outer wall to fit the mortar inlet 7 ', and one side is fixed by the fixing wall 6'. As shown in FIG. When the mortar (10) is put into the inlet (7) is an invention configured to cure by filling in the filling space (a) of the connecting device (A) (B) of the present invention.

At this time, as an embodiment of the connecting device (A), as shown in Figures 4 and 5, the size of the size of the drain pipe (9) (9 ') to be connected to the large range of both sides when a separate connection mechanism (C) is required The inner wall surface 18 'fixed with a fixed wall 6' and forming an outer wall surface 18 with a mortar insertion hole 8 and an inlet hole 7 'and integrally formed with a corrugated support 5 and a fusion point 4; Is configured to form the mortar insertion hole (8 ') in accordance with the insertion hole (8') of the connecting device (C) to fill the mortar 10 in the inlet (7) (7 ') as shown in FIG. It is a product configured to fill the filling space (a) of the device (A) (B) (C).

Figure 2 (b) is a cross-sectional view of the embodiment of Figure 1 by inserting the inlet (7) and the insertion hole (8) in the formwork 20, 20 'of the body of the drainage pipe (11) drainage pipe 11 of the heterogeneous standard It is to connect directly to the drain pipe (11) (11 ') without using the connection device of the connection.

In addition, in the first embodiment of the present invention, as shown in Figures 8 and 9, when used for the connection of the drainage pipe formwork 20 of the same standard to form a mortar insertion hole (8) in the connection portion of the drainage pipe formwork 20 The fixed wall 6 is formed on both sides of the connecting device 1 ', but the mortar inlet 7 is formed in the outer wall 18, and the mortar inlet 7''_ is inserted into the inner wall 18'. After assembling according to the invention, the mortar 10 is filled as shown in FIG. 8 and filled into the inner section of the drainage pipe formwork 20 formed as the mortar filling section. The mortar 10 is fixed according to the inner space 40 (a) of the drainage pipe formwork 20, the junction part 30 and the connecting device 1 '. The invention is to provide a double reinforcement connection method by the formation of a mold, wherein the corrugated support (5) is composed of a synthetic resin support (5) as shown in Figure 10, but the iron core (15) for the improvement of workability, productivity It may be composed only of the iron core (15) and the cross section is to reinforce the durability of the inner wall surface of the drainage pipe (11) filled with mortar (10) When the type of reinforcing rod 14 is integrated, the inner wall surface reinforces abrasion resistance against water pressure or flow rate when water is drained from the drainage pipe.

As a second embodiment of the present invention as shown in Figure 12, 13 as the invention to provide when used as a T connecting pipe 21 according to the design in the construction site of the present invention as one side of the connection device 1 of the present invention A through hole 16 is formed in the inner wall, and a fixed wall 6 is formed on the outer wall, and the corrugated support 5 and the fusion point 4 are fixed to each other. It is a method to cure a certain period of time by assembling the drainage pipe (9) in the t-pipe tube 21 fixed in the (31) to the assembly table (3) to fill with mortar (10).

Therefore, the present invention provides the effect of using the product when it is used to construct the connection site by using elbows and cedusa on the construction site, the use of this product ensures the prevention of leakage of drainage, and is used semi-permanently. It is also used as a connection device for

And as an embodiment of the present invention is a connection consisting of an outer tube which is inserted into the inner wall of the connecting device (1) consisting of the wave support (5) and the fusion point (4) for connecting the drainage pipe (9, 9 ') of the standard Even if the inlet 7 (7 ') and the inlet (8) is fitted with the device (1'), but the fixed wall (6) is configured, the drain pipe (11) is provided and is intended to be connected as an embodiment of the present invention. When the mortar (10) is filled by forming a fixed wall (6), an inlet (7) and an insertion hole (8) at the connection portion of the sultry (20, 20 ') for the (11') Since it is a connection method, a simple invention is provided that does not use a connection device such as a separate Redus yarn as in the prior art by directly using the drainage pipe 11, 11 ′ body. And as an embodiment thereof, the insertion cooking body on the inner side of the connecting device (A) for the connection of the release pipe (9) (9 ') of different specifications with each other inlet (7) (7') It is a nickname that the insertion port 8 is configured to be integrated with each other in the connection part of the drainage pipe 20 and constitutes the fixed wall 6, 6 '. In this case, there are too many standard differences in the connection drainage pipe. 6 ') provides a drainage pipe 23 to be used in the field to fill the mortar (10) in the configuration, and for the connection of the drainage pipe of the same size, the fixed wall (6) and the inlet (7) and Forming the inlet (7 '') but the invention is provided to inject the water drain 10 by assembling by forming the inlet (8) in the circumferential direction at the connection portion of the drainage pipe formwork (20) and the drainage pipe formwork (20) Cross section on inner side for reinforcement of durability and wear resistance of drainage Integrate the reinforcing rod 14 of the mold and insert the iron core 15 or the iron core 15 into the synthetic resin corrugated support 5 to improve the workability of the corrugated support 5. And in the T-connecting tube 21 of the present invention to form a through-hole 16 on one side of the connecting device 1 of the present invention to fix the connecting device (C) of the present invention with an assembly table 31 and mortar (10) It is an invention used to fill the drain pipe, which can be used even in the straight state, not in the bending section, and it is a useful invention that contributes to the saving effect of the drain pipe as much as the use interval of the filtration device. As shown in FIG. 8, in particular, a double connection, that is, a cross-section, of the connection part 30 of the drainage pipe body 9 and the body part 40 of the connection device 1 is used. Providing connection structure of the mold structure, it provides perfect robustness and leakage prevention. The cement mortar 10 is mixed with reinforced sludge or optical fiber chip for durability. At this time, the filling port (2 '), instead of the cement mortar (10) to provide a rigid synthetic resin foam waterproofing agent filled in the input space (A) provides a robustness and leakage prevention effect.
