いう状態である。 Conventionally, in the construction of floor boards for concrete structures, as shown in Fig. 1, many vertical beams 13 are installed along an erected structure 1 such as a pillar or wall, and a horizontal frame is placed on top of these vertical beams 13. A number of beams 5 supporting the floor formwork plates 4 are mounted on the horizontal members 3, and the floor formwork is temporarily constructed, but the construction is complicated and requires a lot of work. It has the disadvantage of requiring equipment.
In addition, in many cases, floor 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 floors than for beams, floor forms should be constructed as soon as possible after the curing period. It would be desirable to remove the floor formwork and repurpose it for another construction site, but this is not possible because the floor formwork is assembled in conjunction with the beam formwork, and a lot of construction equipment is wasted. This is the situation.

が、かかる形状に限定されるものではない。 Reference numeral 1 denotes a structure erected, such as a pillar or a wall, and supports 2, 2 are provided at appropriate positions on opposite sides of the structure 1 at a required interval in the lateral direction. . This support 2 is usually made by inserting a bolt and having its end protrude outward as shown in the figure, but if it can be used to securely attach other members etc. to the structure 1, it can be used. It is not limited to. Further, 6 is a hanging tool which is detachably fixed to the support body 2, and has a mounting part 6a having a rectangular shape in front;
It has a hanging part 6b projecting from the lower end in a right angle direction, and is formed in an L-shape in cross section, and the mounting part 6
A through hole 6c for engaging the support body 2 is provided in the upper part of a, and a through hole 6d for supporting a horizontal member 7, which will be described later, is provided in the hanging portion 6b. The hanging tool 6 is firmly attached to the support 2 by engaging the through hole 6c with the support 2 and tightening the nut 2a. In this embodiment, the hanging tool 6 has an L-shaped cross section, but is not limited to this shape.

ングル材９，９が固設されている。 Further, 7 is a horizontal member, which is a member on which a large number of beams 5, 5 supporting the floor frame board 4 are mounted on the lower surface of the floor frame board 4. 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 has an enlarged head 10a at the upper end and an enlarged head 10a at the lower half. Long hanging bolt 10 with diameter screw 10b
is inserted through the through hole 6d, and the hanging part 6 of the hanging tool 6
b and the upper part 7a of the horizontal member 7 are fastened together by tightening nuts 11 and 12 screwed into the screw 10b. Also, the upper piece 7 of the horizontal member
Angle members 9, 9 for mounting the beam 5 at a predetermined position are fixedly installed on the portion a.

る。 The construction method of the present invention is performed using each of the above-mentioned members. First, the hanging tool 6 connects its through hole 6c to the support
and is fixed by tightening the screw 2a. Then, with the nut 11 loosely inserted into the non-threaded portion of the hanging bolt 10, the hanging bolt 10 is inserted into the through hole 6d of the hanging tool with the threaded portion 10b facing downward.

とができる。 Next, the through hole 7b of the horizontal member 7 is inserted into the lower part of the suspension bolt 10, and the nut 12 is screwed into the threaded portion 10b of the suspension bolt. As a result, the horizontal member 7 is attached to the hanging tool 6 so as to be able to rise and fall freely via the hanging bolts, as shown in FIG. Then, by pushing up the horizontal member 7 together with the hanging bolt 10 and tightening the nut 11, the horizontal member 7 comes into contact with the lower surface of the hanging tool 6 in its raised position as shown in Fig. 2. It will be locked in the state. As described 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 and the like. 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, but this can be done by changing the screwing position of the nuts 11 and 12 up and down. Its 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 10 can be fixed at a predetermined position by a simple operation similar to the above. .
横架材７が上記のように係止されると、次いで
ビーム５，５を所定アングル９，９の間に載架
し、その上に型枠板４の仮設が行なわれる。 Once the horizontal members 7 are locked as described above, the beams 5, 5 are then placed between the predetermined angles 9, 9, and the form board 4 is temporarily installed thereon.

なる。 After the floor concrete 8 is poured and the concrete hardens, the temporary floor formwork is removed. This is first performed by lowering the horizontal member 7. This operation can be easily performed by unscrewing the nut 11. That is, if the nuts 11 are unscrewed, the horizontal members 7 will be unlatched to the hanging tools 6, so the horizontal members 7 will not fall due to their own weight or the weight of the floor formwork. Become. At this time, the hanging bolt 10 also falls downward due to its own weight and the pulling down caused by the horizontal member 10 falling. However, the hanging bolt 10 is hindered by its enlarged head 10a and is suspended from the hanging part 6b of the hanging tool. be prevented. In other words, the horizontal member 7 is suspended in its lowered position as shown in FIG. 4.
この状態になると、横架材７に載架されたビー

すことにより吊具６を撤去するのである。 In this state, a sufficiently large gap 14 is created above the beam 5 mounted on the horizontal member 7, so that the beam 5 and the form plate 4 can be easily removed. Next, the nut 12 is removed to remove the horizontal member 7, and then the nut 2a is removed to remove the hanger 6.

This will help provide the minimum clearance 14 necessary for removal, depending on the height of the beam used, etc.

ものである。 The present invention uses the method described above to temporarily set up and remove floor formwork during floor concrete pouring, so it is possible to replace existing structures without requiring as many equipment and workers as in the past. The hoisting equipment is used to fix the hoisting equipment, the horizontal members are locked to the hoisting equipment so that they can be raised and lowered, and the floor formwork is mounted, temporarily installed, and removed at the raised and lowered positions of the horizontal members. Therefore, the construction of the floor formwork can be carried out easily and efficiently, requiring less equipment, and the temporary installation and removal of the floor formwork can be carried out independently, regardless of other temporary equipment. This makes it possible to remove the formwork early, improve the turnover rate of equipment, and significantly reduce construction costs overall. Also,
The horizontal members are installed on the hanging tools using hanging bolts and upper and lower nuts, so by adjusting the screwing position of the nuts up and down, you can adjust the installation position of the horizontal members and the horizontal position when removing the installed members. It is possible to appropriately adjust the lowering position of the frame members up and down, and it can be adapted to a wide range of floorboard construction.Furthermore, the horizontal members can be lowered by simply unscrewing the nuts at the top. It can be carried out smoothly and rapidly, and has many excellent effects, such as being able to remove floor forms more efficiently.
