Description

[Detailed description of the invention] <Industrial application field> This invention is used by interposing between adjacent face plates when assembling wooden concrete face plates for use in concrete pouring in the field of civil engineering and construction. The present invention relates to an improved coupling member.

<Prior art> The structure of the connecting member conventionally used between wooden concrete face plates for concrete pouring is as shown in FIGS. The clamping pieces 0 are bent alternately upward and downward at right angles to the base plate 02, and are opposed to each other so as to clamp the side edges of the concrete face plate 6.
3, 05, 04, 06 are formed. Then, insert the edge of the wooden concrete face plate 6' with the plate 7 nailed to the frame 8 between the opposing clamping pieces 04 and 06 on one side, and hit the base plate 02 with a hammer or the like to fit it. Insert and secure. Then, insert the edge of another concrete face plate 6 to be installed adjacently between the clamping pieces 03 and 05 on the other side, and fix by tapping or other means so that there is no gap between the face plates 6 and 6'. .

In this way, concrete face plates to be successively adjacent to each other are connected by the connecting member 01 to form one flat concrete pouring surface.

<Problems to be solved by the invention> On the other hand, in the conventional example described above, the clamping pieces of the connecting member 01 are inserted into the adjacent end edges of the adjacent concrete face plates 6, 6', and the concrete is poured by assembling the joint member 01. Since it forms a surface, the connecting member 01
The outer clamping pieces (05 and 06 in Fig. 5) protrude outward from the plate surfaces 7 and 7' of the concrete face plates 6 and 6', so if the concrete face plates 6 and 6' are removed after concrete pouring, , recesses having the same shape as the protrusions of the clamping pieces 05 and 06 remained as traces on the concrete pouring surface, giving an unsightly appearance.
Even if the concavities were repaired with mortar, etc., the adhesion to the underlying concrete was poor, so the problem was that they would easily chip.

Therefore, in order to eliminate the above-mentioned drawbacks of the conventional art, the present invention has proposed a concrete face plate 6, which has the same width as the side surface of the concrete face plate and is to be brought into contact with the base plate of the connecting member that connects the wooden concrete face plate. By forming sharp protrusions to be driven into the frames 8, 8' of 6' in the length direction of the base plate from both the upper and lower surfaces of the base plate, adjacent concrete face plates are firmly connected to each other. In order to prevent traces of the joining member from remaining on the poured concrete surface, the joining member portion does not protrude from the concrete pouring surface, thereby eliminating the extra effort of repairing the concrete surface after pouring. The purpose is to

<Means for solving the problems> The configuration of the present invention for achieving the above object will be explained using FIGS. 1 to 4 corresponding to the embodiments.
The present invention is a connecting member used when assembling wooden concrete face plates 6, and includes a base plate 2 held between the abutting surfaces of concrete face plates 6, 6' that are adjacent to each other in the vertical or horizontal direction. ,
Rising pieces 3, 4 that are connected to one side edge of the base plate 2 in both directions perpendicular to the base plate 2 and abut against the outer surfaces of concrete face plates 6, 6';
It consists of one or more pointed protrusions 5, 5' cut and raised in the longitudinal direction of the substrate part 2 toward the front and back directions at approximately the middle position in the width direction of the substrate part 2, respectively.

<Operation> When the rising piece 4 of the connecting member 1 of the present invention is applied along the rear surface of the frame 8' of the concrete face plate 6' and the base plate part 2 is hit with a hammer or the like, the rising piece 4 The pointed protrusion 5' is driven into the frame 8' while maintaining the correct positional relationship, and the connecting member 1
is firmly fixed in close contact with the inner edge of the concrete face plate 6' at a precise location. Next, when the concrete face plate 6 which is fixed adjacent to the vertical direction or the left and right direction is struck with a hammer or the like along the rising piece 3 of the mounting member 1, the concrete face plate 6
Using the rising piece 3 as a guide, the pointed protrusions 5, 5 of the mounting member 1 bite into the frame 8, and the frames 8, 8' are in close contact with the rising pieces 3, 4, and both concrete face plates 6, The upper surfaces of the plates 7, 7' of 6' can be integrally joined on the same plane. The base plate portion 2 of the mounting member 1 is held between the contact surfaces of the adjacent concrete face plates 6, 6'.

<Example> An example of the present invention will be described below with reference to the drawings. In FIGS. A flat strip-shaped substrate portion 2 having
Then, when assembling, the rising pieces 3 and 4, which are brought into contact with the outer surfaces of the concrete face plates 6, 6' as guides, are placed on one side edge of the base plate 2 and are perpendicular to the base plate 2. They are formed so as to be connected in both directions.

The frames 8, 8' of the concrete face plates 6, 6' are driven into the frames 8, 8' of the concrete face plates 6, 6' at approximately the middle position in the width direction of the base plate 2 in the widthwise direction of the base plate 2, and the frames 8, 8' are connected to the connecting member 1. Multiple pointed protrusions 5, 5' that are firmly connected
is formed protrudingly.

The above embodiment can be manufactured by joining the base plate part 2 and the rising parts 3, 4 by welding with iron plates, but the base part 2 and the rising parts 3, 4 can be made by using a T-shaped steel material of an appropriate size. This makes it easier to obtain materials, saves time in processing, and is advantageous in terms of cost.
FIG. 3 shows a connecting member formed by vertically bending the upright pieces 3 and 4 of the above embodiment alternately by pressing an iron plate, and has a structure that can save materials.

The sharp protrusions 5, 5' need strength because they are driven into the frames 8, 8' to fix them, but since they are cut and raised from the base plate 2 in the length direction as shown in the figure, material can be saved. In addition, it is not only easy to manufacture, but also can be used even if a force is applied to separate the frames 8, 8' from the base plate.
There is no fear that the protrusions 5, 5' will fall down, and the frame is firmly held.

In addition, the pointed protrusions 5, 5' in FIGS. 1 and 3 are formed by punching and standing in the length direction of the base plate 2, but they are formed by cutting them in the width direction of the base plate 2 as shown in FIG. Raised pointed protrusions 5, 5' may be mixed with the above-mentioned protrusions.

When assembling the concrete face plates 6, 6' using the connecting member 1 of the present invention having such a structure, the connecting member 1 is attached to the contact surface of the concrete face plate 6'.
When the rising piece 4 on one side is applied and the base plate 2 is hit with a hammer or the like, the pointed protrusion 5' of the connecting member 1 is driven into the abutting surface and bites, causing the connecting member 1 to be attached to the abutting surface of the concrete face plate 6'. Bond and fix. that time,
The rising piece 4 serves as a guide for the concrete face plate 6', and prevents the connecting member 1 and the concrete face plate 6' from shifting or being distorted, so that the worker can easily carry out the driving work. Next, the contact surface of another concrete face plate 6 to be joined adjacently is applied to the rising piece 3 on the other side of the joining member 1 fixed earlier, and the concrete face plate 6 is hit with a hammer to join. The pointed protrusions 5, 5 of the member 1 are driven into the concrete face plates 6 at precise positions and bite into them, thereby holding both the concrete face plates 6, 6' in the correct relative position and the base portion 2 of the joining member 1. It is strongly bonded through.
