Description

Formwork for connecting flexible reinforced water and sewage pipes in construction and roads {.}

The present invention relates to a formwork for connecting flexible reinforcement water and sewage pipes configured to be suitable for the conditions that are curved in accordance with the topography of construction or road construction site in large diameter drainage pipe.

Conventionally, in the construction site, the elbow should be assembled at the curved part, and the diameter In the case of a large diameter of more than 1200m / m, the box is made of a curved part of the water supply and sewage pipe, or in the case of a larger standard, a concrete reinforcing bar is manufactured. As the work was done in the order of curing and form removal for a certain time after formwork assembly and cement mortar injection, inefficient air was consumed.

The present invention provides easy flexibility to the intermittent bent portion and in the drainage pipe for cement mortar input, the intermediate portion or intermittently bend to form a flexible reinforcing coupling bar in a spiral winding, but the drainage pipe to the coupling table (14) It is intended to provide a strong formwork for connecting water and sewage pipes by combining and injecting the cement mortar into the inlet.

The present invention is a product related to the formwork for connecting the sewage pipes for bending reinforcement as a structural improvement product for his or her proposal application (20-2000-12938), the direction of the water pipes by bending the water pipes according to the design and terrain at the construction site In the case of conversion, conventionally using a separate elbow or forced to bend the water pipes, the present invention is used to connect the formwork for easy connection to the water pipes. Figure 2 is a perspective view of the connecting die, Figure 2 is a partially cutaway side view showing a state of connecting the water and sewage pipe to the connecting die according to the present invention, Figure 3 is a partially cut flat of the connecting die according to another embodiment of the present invention. 4 is a cross-sectional side view illustrating a state in which a water pipe is connected to a connection formwork and a cement mortar is poured in accordance with another embodiment of the present invention, and FIG. Some cutaway cross-sectional view showing a state connecting the water and sewage pipe in the curved formwork for connection according to the invention, Figure 6 is a protective wall and reinforcement formed on the outer surface and the socket portion of the connection formwork according to the invention Some cutaway sectional drawing which shows the state.

Therefore, the connecting die 11 of the present invention forms the inner surface 13 and the outer surface 15 to a predetermined length, but is formed to be spaced apart at a predetermined interval, the outer side surface 15 to the inner side of the central portion side. (13) is bent to the fusion splice 14 in the spiral winding direction a plurality of times. Further, the inner side 13 is bent into a spiral winding to the outer surface 15 side to form an inclined reinforcement table 34, Bending and fusion to alternately position the coupling table 14 to reinforce the durability. And, both sides of the inner surface 13 and the outer surface 15 has a socket portion 18, the insertion space 12 is formed It is provided by inserting the water and sewage pipe 20 to install the cement mortar (17) in the insertion space 12, the connection, and to be used according to the terrain of the construction site. To this end, the outer surface 15 is formed with a plurality of inlets 16 through which the cement mortar 17 can be introduced.

In addition, as the connecting die 11 according to another embodiment of the present invention, the inner surface 13 is bent in the direction of the outer surface 15, but not fused to the outer surface 15, like the inclined reinforcement 34, Form a flexible groove 35 in a curved form. In the large diameter of 1200m / m or more, the insertion space 12 must be maintained in a circular shape so that the water and sewage pipe 20 can be easily inserted, thereby reinforcing the durability of the outer surface 15 and reinforcing the robustness of the socket 18. In order to increase the reinforcement by integrally joining the protective wall 23 to the outer side, the reinforcement 19 is integrally formed in the spiral winding direction to the protective wall 23. In addition, formed in the socket portion 18 In the insertion space 12 is inserted into the belt 25 is formed with a resilient table 26 to block between the inserted water and sewage pipe 20 and the socket portion 18.

Therefore, inserting the end of the water and sewage pipe 20 to be connected to the insertion space 12 of the socket portion 18 provided on both sides of the connecting die 11 of the present invention, for connection according to the curved state of the construction site Then, the formwork 11 is bent. Then, the connecting formwork 11 is connected to the curved portion 14 and the inclined reinforcement stand 34 of the inner portion is bent in accordance with the state of being curved, narrowed, the outer portion of the curved As the coupling table 14 and the inclined reinforcing bar 34 are extended, the spacing becomes wider. Then, the belt 25 is inserted between the socket portion 18 and the water and sewage pipe 20, and the elastic band 26 is provided. Compression is possible by inserting, and after insertion is completely blocked between the socket portion 18 and the water supply and drainage pipe 20 by elasticity.

When the cement mortar 17 is inserted through the insertion hole 16 in this state, the cement mortar 17 is filled in the insertion space 12 of the socket portion 18 and connected without leaking to the outside by the belt 25. The mold 11 and the water pipe 20 are firmly coupled to each other, and the cement mortar 17 is filled and cured between the inner side 13 and the outer side 15 of the intermediate portion, thereby being firmly curved. In addition, the socket portion 18 and the outer surface 15 are protected by the outer protective wall 23, and the reinforcement 19 can withstand the external pressure even after being connected and embedded. Robustness is reinforced.
