[Structure] A work floor 6 having a width matched to the space between the joists 2 is formed, pin holes 6a are opened at four corners of the work floor 6, and at least between the pin holes 6a and 6a of two adjacent work floors 6, By inserting pins 7a, 7a protruding from the fixing metal fitting 7, both working floors 6 laid on the joist 2 are fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for fixing a temporary work floor during construction of a house.

[0002]

[Prior art]

 In the past, when constructing a house, in order to ensure safety when working on the second floor after constructing the pillars, a work floor made of thick veneer was laid on the joists. As shown in Fig. 4, this work floor is fixed by fixing joists 2 and 2 on the floor beam 1 so that other work can be performed safely before the floor is laid on it. The floor 3 was laid on top of each other.

[0003]

[Problems to be solved by the device]

 However, since the work floors 3 are laid one on top of the other, the work floors need to be larger than the floor area, and the number of work floors increases, and the upper part of the overlapping part is exposed on the floor surface. It is easy to trip over, and because the work floor is simply placed on the joists 2.2 ..., the stability is poor, and the work floor tends to slip each time you walk on the work floor 3. If the feet are placed on the work floor 3 ', which is displaced from the joists 2 as shown by the chain line, there is a risk of falling downstairs or below the floor. And because there was a concern about falling like this, there was anxiety, walking was slow and careful, and work efficiency was also reduced.

[0004]

[Means for Solving the Problems]

 The problems to be solved by the present invention are as described above, and in order to solve the problems, a working floor having a width matching the space between joists is constructed, and pin holes are opened at four corners of the working floor to reduce Both work floors laid on the joists are fixed by inserting pins protruding from the fixing brackets between the pin holes of two adjacent work floors.

[0005]

[Action]

 With the above-described configuration, the work floor 6 can be laid on the joist 2 without overlapping the ends, and at least two sides of the work floor 6 are located on the joist 2 and the adjacent work floors 6 can be arranged. When the pin 7a of the fixing member 7 is inserted into the pin hole 6a, the two pins 7a are inserted with the joist 2 in between, and the work floor 6 is fixed without displacement. Then, by properly changing the direction in which the pins 7a and 7a are connected, it is possible to prevent the front-back and left-right deviation.

【Example】

 The problems to be solved and the means for solving the present invention are as described above. Next, a specific configuration of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a fixed structure of a work floor according to the present invention, FIG. 2 is a front sectional view of the same, and FIG. 3 is a plan view showing a state in which the work floor is temporarily laid.

When constructing a house, the pillars are built in the same manner as in the conventional method, and the joists 2 and 2 ... are laid on the floor beam 1 at regular intervals, and then the working floor 6 of the present invention is joisted. It is laid on top of 2. The width L1 of the work floor 6 is the same as the space between the joists 2, and the vertical length L2 of the work floor 6 is twice the width (2 × L1 = L2). In this embodiment, the width L1 is 100 × 200 cm. The length. However, although thick veneer is used as the work floor 6 in this embodiment, an iron plate or the like may be used.

Further, at the four corners of the work floor 6, pin holes 6a, 6a having a diameter L4 are opened at positions inside the length L3 from both end sides, and only four corners are formed without opening a large number so as not to reduce the strength. The length of L3 is opened so that the length between the pin holes 6a and 6a of the adjacent work floor 6 is longer than the width L5 of the joist 2 (2 × L3> L5). Between the work floors 6 and 6, the pins 7a and 7a are inserted, and the distance L6 between the pins 7a and 7a is longer than twice the length of L3 (2 × L3 <L6). There is a gap so that there is a margin. When the four corners are dropped and laid down, there is a space in the corner that allows easy removal. In this embodiment, the distance L6 between the pins 7a and 7a is 75 mm, L3 is 35 mm, and the width L5 of the joist 2 is 60 mm.

The fixing member 7 is formed in a π shape in a side view by vertically arranging pins 7a, 7a on both sides of a rectangular plate 7b, and the diameter L7 of the pin 7a is larger than the diameter L4 of the pin hole 6a. Is smaller (L4> L7), and the pin 7a is longer than the thickness of the work floor 6. Then, the edge of the upper surface of the plate 7b is chamfered to prevent stumbling and scratches from occurring. In this embodiment, the diameter L4 of the pin hole 6a is 15 mm and the diameter L7 of the pin 7a is 9 mm.

As shown in FIG. 3 using the work floor 6 and the fixing bracket 7 configured as described above, when the work floor 6 is spread over the joist 2 and the pin 7a of the fixing bracket 7 is inserted into the pin hole 6a, It does not come into contact with the wall 9 when it is displaced to the left, and when the displacement is to the right, the fixing metal fittings 7 ′ sandwich the joist 2 so that the displacement is prevented and the displacement in the front-back direction is fixed. Since the joists 2 are sandwiched by the fixed metal fittings 7 ″, the joists 2 are prevented from being displaced, and by thus laying the entire floor, it is possible to construct a flat temporary work floor.

[0011]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. That is, the work floor can be laid flat without having an overlapping part on the joists, the working floor can be reduced, and the floating part generated at the overlapping part of the working floor is eliminated, and the work floor stumbles. Moreover, since the work floor does not slip off, there is no slippage and the work can be done with peace of mind, and the workability was improved. In addition, since the work floor can be laid or turned from any place, it is possible to further reduce the number of work floors and to lay the necessary part, which makes the work easier. Since the work floor and fixed fittings can be used repeatedly, running costs could be reduced.
