Description

[Detailed Description of the Invention] The present invention relates to a floor plate form support device that simplifies the assembly and removal of the floor plate form during the construction of concrete structures.

Conventionally, in the construction of floor boards for concrete structures, as shown in Fig. 1, many vertical beams 13 are installed along a structure 1 such as a pillar or wall, and these vertical beams 1 are
A horizontal member 3 is fixed on top of the horizontal member 3, and a number of beams 5 supporting the formwork plates 4 are mounted and fixed on the horizontal member 3, and the floor formwork is assembled. The disadvantages are that it is complicated and requires a lot of equipment. In addition, in many cases, floorboard construction is carried out at the same time as beam construction, but since the period of time required for concrete to cure is shorter for floorboards than for beams, floorboard formwork is installed at the same time as the curing period for the floorboards. It would be desirable to remove it as soon as possible and use it for another construction site, but since the floor plate formwork is supported in conjunction with the beam formwork, this is impossible and a lot of equipment would be wasted. It is a state of being.

The present invention was developed in view of the above-mentioned drawbacks of the conventional technology, and provides unique support for the floor plate formwork.
To allow the horizontal members to be supported by supports provided on the structure, to be able to be raised and lowered, and to be locked at the raised position, so that floor forms can be assembled and removed independently and extremely easily. It is an object of the present invention to provide a floor plate formwork support device that can perform the following functions.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 to 4.

Reference numeral 1 indicates an existing structure, which is an upright part such as a pillar or wall, and supports 2, 2 are inserted horizontally into the appropriate positions of this structure 1, and the ends thereof protrude outward. has been done. Further, reference numeral 6 denotes a hanging tool having an L-shaped cross section and having a mounting part 6a having a rectangular shape in front and a hanging part 6b protruding from the lower end of the mounting part 6b in a right angle direction. through hole 6c
In addition, the suspension portion 6b is provided with a through hole 6d for supporting a horizontal member 7, which will be described later. The hanging tool 6 can be firmly attached to the support 2 by engaging the through hole 6 with the support 2 and tightening the nut 2a. In this embodiment, the hanging tool 6 is formed to have an L-shaped cross section, but is not limited to this shape.

The horizontal member 7 is for mounting a number of beams 5, 5 supporting the floor board formwork 4 on the lower surface thereof, and angle members 9, 9 are fixed on the upper surface thereof for mounting the beams 5 in fixed positions. has been done. And horizontal member 7
is installed on the plurality of hanging tools 6 described above so as to be able to rise and fall freely. That is, the upper piece 7a of the horizontal member 7 is provided with a mounting hole 7b at a position corresponding to the through-hole 6d of the hanging tool 6, and an enlarged head 10 is provided at the upper end.
In addition, a long hanging bolt 10 having an enlarged-diameter screw portion 10b in its lower half is inserted through the through hole 6d, and connects the hanging part 6b of the hanging tool 6 and the upper piece part 7a of the horizontal member 7.
is the nut 11 screwed into the enlarged diameter threaded portion 10b,
12, and when the upper nut 11 is turned to unthread the threaded portion 10b, the horizontal member 7 descends as shown by the arrow due to its own weight. The lowered position is as shown in the chain lines in FIGS. 2 and 3 and in FIG. 4. If, on the other hand, the horizontal member 7 is pushed up and the nut 11 is screwed into the enlarged diameter screw portion 10b and tightened, it will be locked in the raised position as shown in Figures 2 and 3. .

As mentioned above, the horizontal member 7 is a member for mounting the beam 5, but the height h of the beam 5 used may change depending on the construction state etc. In such a case, it will be necessary to change the height of the mounting position of the horizontal member 7 with respect to the hanging tool 6.
By changing the screwing positions of 1 and 12 up and down, the mounting position can be freely adjusted up and down. Further, even if the height of the support body 2 provided on the structure 1 is set vertically unevenly, the height of the horizontal member 7 can be fixed at a predetermined position by a simple operation similar to the above. .

To use the device of the present invention, as shown in the figure, attach the hanging tool 6 to the support body 2, screw together the bolt 10 and nuts 11, 12 as shown in FIG.
is held at a lowered position spaced below the hanging tool 6. Next, the ends of each beam are mounted on the horizontal member 7, and the horizontal member 7 is pushed up and the nuts 11 are tightened to lock it in the raised position as shown in FIGS. 2 and 3. In this case, the floor plate formwork 4 in its raised position
Of course, it is set at a predetermined position. After the concrete has been poured and the curing period of the floorboards 8 has ended, the floor formwork is removed, but at that time, by unscrewing the nuts 11, the horizontal members 7 will move under their own weight. 4 Lower it to the lowered position as shown in Figure 4. In this state, there is a sufficiently large gap 14 above the beam 5 placed on the horizontal member 7, so that the beam 5 and the form plate 4 can be easily removed. Next, by removing the nut 12, the horizontal member 7 can be removed, and by removing the nut 2a, the hanging tool 6 can be removed.

In this embodiment, by adjusting the screwing position of the nut 12 up or down, the lowering position of the horizontal member 7, that is, the height of the gap 14 can be adjusted. This will help provide the minimum gap 14 required for removal, depending on the size of the beam used.

As explained above, the present invention has a plurality of supports protruding from a structure, each of which is removably attached to a plurality of supports, each having a protruding suspension part. , disposing a horizontal member on which the end of the beam of the floor formwork is placed, and having an enlarged head at the upper end in the through hole provided in the suspension part and the mounting hole provided in the horizontal member. Insert a long suspension bolt with an enlarged-diameter thread in the lower half, and connect the horizontal member to the hanging tool by sandwiching the suspension receiving part and the horizontal member between the nuts screwed onto the upper and lower parts of the enlarged-diameter thread. Since the floor plate formwork can be supported independently from other temporary structures, it is possible to quickly remove only the floor formwork, and the horizontal members on which the beams are mounted can be suspended. Since the structure is installed using bolts and upper and lower nuts, by adjusting the screwing position of the nuts up and down, the installation position of the horizontal member and the lowering position of the horizontal member when removing the member can be adjusted. can be adjusted up and down appropriately, and can be widely adapted to the construction of floorboards.Furthermore, the horizontal members can be lowered smoothly and quickly by simply unscrewing the nuts at the top. The removal work of the floor formwork can be easily and reliably carried out, and since the overall structure of the device is simple, it can be manufactured at a low cost. This has a great effect on savings.
