Description

[Detailed description of the invention] The invention is used when pouring and forming concrete walls that require drainage after construction, such as retaining walls and surrounding walls in reclaimed land. At the required points on the concrete wall,
The present invention relates to a device for holding a drain pipe, which forms a drain passage penetrating the wall in the thickness direction, in a position between opposing assembly forms for making a concrete wall.

This type of device, which has been used conventionally,
As shown in the figure and FIG. 8, the opposing assembly formwork 012
on each side, a pipe end position holding member 06 that can be elastically fitted to the end of the drain pipe 01;
Peripheral frame 012 of vertically adjacent formworks 012A, 012A that is integrally connected to or can be fixedly connected to hard core material 06A that is embedded and fixed within its wall thickness.
a, 012a, and a formwork abutting member 07 that applies an outward moving force to the mounting plate piece 02 using the formworks 012A, 012A as reaction force members. and the base end thereof is attached to the formwork 012A, 0 through the bolt/nut 08.
The pipe end position holding member 06 is configured to be able to be fixedly attached and removed in a state in which it is brought into elastic contact with the inner surface of the pipe end position holding member 06.
The peripheral frames 012a, 0 of the formworks 012A, 012A, which are vertically adjacent to each other, are attached to the formworks in the vertical direction.
Since it is restricted by the overlapping location of 12a,
The range in which the water draining pipe 01 can be held in a state where its axially opposite end openings are vertically displaced, that is, in a state where it has a drainage slope, is as narrow as the elastic deformation range of the position holding member 06 itself. It had the disadvantage that it was not possible to set an arbitrary drainage slope. Furthermore, if one were to obtain an arbitrary drainage slope with the conventional device described above, it would be necessary to form holes in the face plate of the formwork through which the mounting plate piece 02 could be inserted, depending on the desired slope. This has the disadvantage of causing a large amount of formwork loss and increasing running costs for contractors and the like.

In view of the above-mentioned circumstances, an object of the present invention is to provide a holding device for holding a pipe for draining water from a concrete wall to a formwork, which allows an arbitrary drainage slope to be obtained without the need for drilling holes in the face plate of the formwork.

The device for holding a concrete wall water drain pipe to a formwork according to the present invention, devised to achieve the above object, is arranged between the peripheral frames of the upper and lower adjacent formworks on each side of the opposed assembly formworks. A pair of upper and lower mounting plates that can be inserted and fixedly attached to and removed from the formwork are connected between the inner ends of these pair of upper and lower mounting plates, and when fixedly attached to the formwork, the upper and lower parts are attached to the inner surface of the formwork. A pipe mounting frame is provided, which is approximately U-shaped in side view and has long holes in the vertical direction formed in the strip pieces in the vertical position. It has a characteristic configuration in which a pipe end position holding member that can be elastically fitted into the end of the pipe is attached to the posture band plate piece so that the position can be changed and fixed up and down along the elongated hole, and the following It has come to have effects.

In other words, by inserting the upper and lower pair of mounting plate pieces of the pipe mounting frame between the peripheral frames of the upper and lower adjacent formworks and fixing them to the formwork, the vertical posture band plate pieces of the pipe mounting frame can be fixed. It can be positioned along the inner surface of the formwork, and by changing the vertical position of the pipe end position holding member attached to the vertical posture band plate piece along the elongated hole, the vertical width of the formwork face plate part can be adjusted as desired. It can be fixed in position. Therefore, there is no need to make any holes in the formwork face plate, and it is possible to suppress formwork loss and securely attach it to the formwork by using the space between the overlapping peripheral frames of vertically adjacent formwork. However, by changing and fixing the vertical position of the pipe end position holding member, it has become possible to hold the drain pipe in a freely inclined posture and form a drain path with an arbitrary slope.

Embodiments of the present invention will be described in detail below based on the drawings.

Figure 1 shows a concrete retaining wall 1 in which drain passages 11 are formed at required locations in the wall thickness direction.
FIG. 2 shows a state in which the drain pipe 1 for forming the drain passage 11 is held in position between the opposing assembly forms 12 and 12 for creating a concrete retaining wall. The device is constructed as follows.

In FIGS. 3 to 5, 5 is a pipe mounting frame, which is connected to the opposing assembly form frames 12, 12.

Formwork 12A, through between peripheral frames 12a, 12a of
A pair of upper and lower mounting plate pieces 2, 2 that protrude to the outside of 12A are integrally connected between the inner ends of these pair of upper and lower mounting plate pieces 2, 2, and when fixedly attached to the formworks 12A, 12A. Face plate portion 12b of formwork 12A
It has a strip plate piece 3 positioned vertically along the inner surface of the plate, and is formed into a substantially U-shape in side view by bending a single thin strip plate.
A long hole 4 in the vertical direction is formed in the strip plate piece 3 in the above-mentioned vertical position and has a length extending substantially over the entire length thereof. Male threaded members 8, 8 are fixedly connected to the outer ends of the pair of upper and lower mounting plate pieces 2, 2 via screw staking 13, 13, respectively.
8 has holes 7a, 7a through which the adjacent formworks 12A, 12A are overlapped and peripheral frames 12a,
Formwork fitting members 7, 7 that can be engaged with 12a from the outside
By tightening wing nuts 9, 9 which are screwed onto the male screw members 8, 8 as reaction members, the pipe mounting frame 5 can be fixedly attached to and detached from the formworks 12A, 12A. It is configured.

6 is a pipe end position holding member that can be fitted into the end of the pipe 1 in an elastically deformed state, and as shown in FIGS. 6 and 7, this is a square core material 6A made of a hard resin such as hard vinyl chloride. A tapered soft sponge 6B is integrally fitted and fixed thereto, and a female threaded hole 6a is formed at the proximal end side of the square core member 6A. Reference numeral 14 denotes a mounting fitting consisting of a male threaded portion 14a that can be screwed into the female threaded hole 6a, a square shaft portion 14b that fits into the elongated hole 4 in a non-rotating state, and a retaining head 14c. The head 14c is placed against the back surface of the vertical posture strip piece 3, and the male threaded portion 14 projects inward.
By screwing the female screw hole 6a into the pipe end position holding member 6, the pipe end position holding member 6 is attached to the pipe end position holding member 6 so as to be vertically changeable and fixed along the elongated hole 4.

By arbitrarily changing and fixing the vertical position of the pipe end position holding member 6 on each side of the opposing assembly forms 12, 12, the inclination of the drainage pipe 1 with respect to the horizontal plane is adjusted, and concrete is poured. By later dismantling the formwork and removing the pipe end position holding member 6, the drain passage 11 with the desired drain slope is created.
This leads to the formation of
