Description

Curved reinforced drainage tolerant formwork {omitted}

The present invention relates to a curvilinear reinforced concrete drainage formwork adapted to the conditions of curvature of the drainage canal of a large diameter, in particular in accordance with the topography of the construction site.

Generally prepared from the construction site in a separate case elbow of assembly, or, in the case where the diameter of the standard, or more φ 1200mm large diameter in the difficult and is connected to a curved portion of a multiple tube operation or drainage tube is larger standard specification of reinforced concrete to the curved portion As a reality that is used as a box which is used as a box, there is a lot of inefficient work air in the box making process, in order of prosecution, inner form assembly, rebar assembly, outer form assembly, cement mortar insertion, In addition, the drainage pipe used for underground burial is to be further destroyed during the burial construction. In many cases, the buried buried rocks and facilities are bent during the construction, and the connection pipe is often used

In the present invention, in the case of providing an easy flexibility to the intermittent curved portion and a drainage duct formwork for cement mortar input, intermittently a curved reinforcing connecting rod is formed on the intermediate portion in a spiral winding circuit, And a cement mortar is put into the inlet to provide a strong drainage form.

The present invention relates to a product with improved structure for a draft application for a curved reinforcing drainage duct (20-2000-12938).

In general, when the drainage pipe is curved according to the design and topography at the construction site, the drainage pipe is bent and used separately. Alternatively, the drainage pipe may be bent and used. The conventional hollow spiral tube having a hollow spiral groove formed in the spiral winding circuit 13 at a constant interval is too small in the structure of the hollow sphere 42 and there is no space for loading the cement mortar 17, In the soft ground where the external earth pressure reinforcement is too weak, there is a problem that it is difficult to use stably in the soft ground where a lot of external earth pressure acts. As a design for effectively reinforcing the strength and the field workability, as shown in FIGS. 1, 2 and 3 A reinforcing hole 39 for enlarging a height H and a width P providing an area of 1.5 times or more of the height h and the width p of the hollow hole 42 formed in the conventional spiral tube, The mortar 17 is provided at one side of the upper side of the reinforcing hole 39 at the site of construction so that the mortar 17 can be used to fill the reinforcing hole 39 with the cement mortar 17, Therefore, in the present invention, there is a problem in that a connecting pipe such as a separate elbow is used when the drain pipe is curved according to the design and construction conditions at the construction site. In the present invention, The inner side surface 13 of the reinforcing member 39 is intermittently bent along the longitudinal direction as shown in Fig. 4 by bending the inner side surface 13 of the reinforcing member 39 into the hollow section of the reinforcing member 39 with the flexible side groove 35 The mortar 17 is put into the inlet 16 to fill the mortar 17 in the inner space of the reinforcing hole 39 to cure the mortar 17 for a certain period of time, Destroyed soil The document gives ever buried underground.

5, the other structure of the curvable meandering groove 35 on the inner side surface 13 of the present invention is different from the curved groove groove 35 in that the inclined reinforcing base 34 and the outer surface of the reinforcing opening 39 (15 ') to the upper surface of the reinforcing member (39) with the joining piece (14').

6, in order to provide the external earth pressure reinforcement for the long-term stable use of the product due to the bad condition of the construction site where the form 11 provided in the present invention is buried in the ground, A reinforcing opening 39 is formed at the curved portion where the inclined hollow groove 35 is formed and the reinforcing opening 39 is formed by the engaging base 14 and the reinforcing opening 39, And the inner side surface 13 formed at regular intervals between the inner side surface 13 and the inner side surface 13.

In order to reinforce the curvature and outer earth pressure reinforcement in the product described above, the reinforcement ribs 38 are formed on both side walls of the reinforcement hole 39 as shown in FIG. 7, and the outer wall surface 23 is bent And a reinforcing groove 37 is formed at the bent portion of the inner side surface 13 in place of the flexible shoulder groove 35 to provide a curved and outer reinforcing product .

8, the inner side surface 13 is bent by the inclined reinforcing bar 34 and the coupling base 14 so as to be integrated with the outer side surface 15 of the reinforcing hole 39 A given product is provided with a product that is more reinforced than the mold described above.

The description of the embodiment of the present invention is based on the fact that an intermediate side 40 dividing the longitudinal direction into two portions is formed between the inner side surface 13 and the protective wall 23 to form reinforcement openings 39 'Is bent in an alternating manner along the longitudinal direction on the inner side surface 13 and the protective wall 23 on the curved portion which is to be bent in the helical tube reinforced by the double layer structure, Bending the protection wall 23 with the coupling base 14 and the coupling base 14 to secure the intermediate side 40 to the reinforcing support base 41 'while fixing it to the coupling base 14, It is a product that provides durability to provide reinforcement and external earth pressure.

Herein, as shown in FIG. 10, in the description of the present invention in which curved devices are shown along a longitudinal direction at regular intervals, a mortar filling space (not shown) formed by bending the inner side surface 13 and the outer side surface 15 in a curved portion section The mortar input port 16 is formed in the longitudinal direction on the protection wall 23 of the cement mortar 12 to assemble the mold 11 of the present invention for performing the directional movement to the curved road while being buried along the drain pipe at the construction site, 16) is filled into the filling space through the inlet (16) and cured for a predetermined time. At this time, in order to provide the rigidity of the filling space 12, the mortar 17 is inserted into the inner wall 13 and the outer wall 15 on the inner wall 13, as shown in FIGS. 11 and 12, The upper and lower protrusions are formed in the spiral winding direction in place of the both side walls and the outer side surface 15 in the filling space 12 of the drainage pipe 11 between the curved reinforcing portions in the drainage pipe 11 in which the space 12 is formed. The cement mortar inlet 16 is formed on one side of the corrugated support 28, the upper and lower protrusions, the inner side 13 and the protection wall 23 by a welding point 27, As shown in FIG. 13, and is filled with cement mortar and used in the filling space 12 as shown in FIG.

The present invention provides a curved reinforced drainage duct formwork which provides not only the connection site but also the curvature of the curved reinforced bar formed intermittently in the drainage pipe when the building moves from the construction site to the drainage pipe, thereby providing workability and economical efficiency. It is a useful product that is provided with construction and economical efficiency by providing reinforced drainage pipe such as concrete infiltration and reinforced drainage pipe by filling concrete with cement mortar in the form of this invention provided by reinforcing a synthetic resin spiral pipe in the field.
