Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a temporary floor for preventing horizontal and vertical misalignment between floor panels of a temporary floor laid side by side in a building used for multiple purposes. Regarding the panel support mechanism.

BACKGROUND OF THE INVENTION Recently, many buildings have been constructed on the assumption that they will be used as so-called multipurpose halls. In this case, the floor of the building is usually finished with concrete, and the floor can be used to hold meetings, events, exhibitions, expositions, product exhibitions, etc., and can also be covered with ice and used as a skating rink in the winter. There are many things. Furthermore, by forming a temporary floor by laying out a large number of floor panels at a predetermined height from the concrete floor surface, various ball games such as basketball, volleyball, tennis, and handball, as well as judo, kendo, track and field events, etc. can be played on the temporary floor. It may allow you to play any sport.

When constructing a temporary floor like the one above, place supports (takagi or lumber) at a certain height on the concrete floor surface.
A rectangular, predetermined area of wooden floor panels are laid out on top of the supports.
Since the concrete floor surface lacks flatness and has many uneven surfaces, differences in level may occur in the floor panels. This step is particularly unsuitable for sports, as it can cause rattling or misalignment between the panels when landing after rapid exercise, or misalignment due to vertical steps, etc., and should be prevented. In order to do this, grooves are provided at the four corners of each floor panel in the thick part parallel to the surface of the floor panel, and at the intersection where the four corners of the four floor panels converge, a metal circle is placed in the groove. A corner fitting made of a board is inserted. Therefore, the four corners of the four floor panels are fixed against vertical movement.

Problems to be Solved by the Invention However, according to the above-mentioned conventional technology, the vertical wobble of the floor panels can be prevented to some extent by using the corner fittings, but since the corner fittings are only inserted into the grooves, the floor panels do not intersect with each other. Connection between them is not possible. Furthermore, the misalignment of the edges of the floor panels cannot be adjusted. That is, even if grooves are provided on the long and short sides of the floor panel into which fittings similar to the corner fittings are inserted, their placement positions are determined in advance and cannot be moved arbitrarily.
In other words, the position where misalignment occurs due to the unevenness of the concrete floor can only be known at the time of construction on site, and it is only by adjusting that position that misalignment can be prevented. It is wasteful to keep it installed, and
This results in higher costs.

Therefore, in view of the above circumstances, the present invention is capable of connecting frames that support the floor panel at a predetermined height from the installation surface, and can be attached to all four sides of the floor panel by sliding it to any position. The aim is to provide a support mechanism for temporary floor panels that can respond immediately to on-site conditions.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a main body having a predetermined height from the installation surface, and a support part that is formed to extend from the top of the main body to both sides and on which a floor panel is placed and fixed. a frame extending from the main body parallel to one of the supporting parts and at a constant interval; and bending the ends of the frame and the one supporting part in directions facing each other. a pedestal having a locking part formed by the above-mentioned locking part; and a part that fits into the groove formed by the support part and the frame part and is fitted in such a way that it cannot fall off through the locking part, formed in a line-symmetrical arrangement. A support mechanism for a temporary floor panel consisting of a connecting member, and
A main body having a predetermined height from the installation surface, a support part extending from the top of the main body to both sides and on which a floor panel is placed and fixed, and a support part parallel to one of the support parts and having a constant interval. A pedestal comprising: a frame portion extending from the main body; and a locking portion formed by bending the frame portion and the end portions of the one support portion in directions facing each other; A part that movably fits into the groove formed by the frame part and also fits into the groove so that it cannot fall out via the locking part, and a part which fits into the groove formed by the support part and the frame part so that it can be inserted and removed. A support mechanism for a temporary floor panel is constructed, which includes a vertical movement prevention member and a vertical movement prevention member.

Effects According to the above configuration of the present invention, the four corners of the pedestal on which the floor panel is placed and fixed are connected to each other by the connecting member, and are prevented from separating and moving up and down. Further, the frames disposed on the sides of adjacent floor panels are prevented from moving in the vertical direction with respect to each other with the interposition of the vertical movement blocking member.

Examples Examples of the present invention will be described below based on the drawings. In FIG. 1, reference numeral 1 denotes a temporary floor, in which a plurality of floor panels 1a are laid horizontally on a concrete floor at a predetermined height via a pedestal 4. The frames 4, 4 between the adjacent floor panels 1a, 1a are connected at the four corners by connection members 2, and vertical movement prevention members 3 are interposed at the sides.

The pedestal 4 has a main body formed by a box-like body with a hollow interior 6 formed by a bottom portion 4c, side walls 4a, 4b, and a top portion 4d, and side walls 4a, 4 following the top portion 4d.
It consists of horizontal support parts 7 and 8 that are integrally formed and project toward the b side, and a frame part 9 that is formed and project from the side wall 4b in parallel with the support part 8 at a predetermined distance. The floor panel 1a is placed on the support parts 7 and 8, and connected and fixed with wood screws 15, and the end faces of the support part 8 and the frame part 9 are bent at right angles, and an inclined surface 13 is formed on the inner surface thereof. A locking portion 12 is provided. The inclined surface 13 of the support part 8 is formed to be inclined downward, and the inclined surface 13 of the frame part 9 is formed to be inclined upward. A groove 11 is formed between the support part 8 and the frame part 9,
An opening 10 having a constant height is formed between the locking parts 12, 12. This pedestal 4 is made by cutting a long material made of extrusion molded aluminum alloy into long materials corresponding to the lengths of the long and short sides of the floor panel 1a, and cutting the ends of each long material into long materials corresponding to the lengths of the long and short sides of the floor panel 1a. As shown in FIG. 2, it is cut at an angle of 45 degrees in the width direction, and the cut parts 5 are butted against each other to form a perpendicular part. Furthermore, the locking portions 1 of the supporting portions 8, 8 are located at the corners of the orthogonal portions and are orthogonal to each other.
2 and 12 are cut out, and an insertion opening 17 for the connecting member 2 is formed inside the cutout lines 16 and 16, as shown in FIG.

Note that as another method for forming the insertion opening 17, the end portion of the elongated material cut at 45 degrees may be further cut off along the perforation line 16.

The orthogonal portions are arranged on the back side of the four corners of the floor panel 1a. This long material is connected to the long side and short side of the back surface of the floor panel 1a by screwing the wood screws 15 into the supporting part 7 and the top part 4d as described above, with the supporting part 8 facing outward. Then, a pedestal 4 made of a frame of elongated material surrounding the back surface of the floor panel 1a is formed.

The connecting member 2 is a block body having a predetermined length and a substantially H-shaped cross section, and is connected to the groove 1 of the mounts 4, 4.
1 and 11 are arranged symmetrically on both sides, and each of the leg parts 2a is formed with an inclined surface 14 that slides into contact with the inclined surface 13. 18 is a through hole bored in the cross-sectional direction of the connecting member 2. This connecting member 2 includes floor panels 1a, 1
This is for connecting adjacent frames 4, 4 at the four corners of a.

A vertical movement blocking member 3 is interposed between the frames 4, 4 on adjacent sides of the floor panels 1a, 1a. As shown in FIGS. 3 and 4, this vertical movement blocking member 3 has one leg 2a of the connecting member 2, whereas the connecting member 2 has a substantially H-shaped cross section.
It has a substantially T-shaped cross-sectional shape with 2a cut out,
The frame 4 has an inclined surface 15 in sliding contact with the inclined surface 13.
It has leg parts 3a, 3a that fit into the groove 11 of the frame 4, and an end part 3b that fits into the groove 11 of the pedestal 4.

To explain the operation of the above embodiment, FIG.
The figure shows the state in which the bricks are laid side by side at the joints, and there are connection members 2 at the four corners of each floor panel 1a.
An example is shown in which a vertical movement blocking member 3 is used on each adjacent side portion. That is, when a plurality of floor panels 1a are laid out with their long sides and short sides facing each other, the grooves 11, 11 face each other as shown in FIGS. 1 to 4. Therefore,
In the case of the four corners of the floor panels 1a, 1a shown in FIGS. 1 and 2, the connection member 2 is inserted through the insertion openings 17, 17 (FIG. 2) formed at the corners of the orthogonal frames 4, 4. , its symmetrical legs 2a, 2a, 2
Hammer in the horizontal direction with a wooden hammer, plastic hammer, etc. so that a and 2a fit into the grooves 11 and 11, respectively. Therefore, the inclined surface 13 formed on the locking portion 12 of the pedestal 4 and the inclined surface 14 formed on the leg portion 2a of the connecting member 2 come into sliding contact with each other, thereby preventing the leg portion 2a from slipping out from the groove 11. . Therefore, even if the left and right frames 4, 4 do not move in the direction away from each other, the locking portion 12 and the connecting member 2 prevent the movement. Furthermore, when one floor panel 1a and the frame 4 integrated with it do not move in the vertical direction, the locking parts 12, 12 hold the connecting member 2, so the other floor panel 1a does not move in the vertical direction. and is regulated by the frame 4 to prevent misalignment.

In addition, when dismantling the temporary floor 1, the connecting members 2
One end of a tool such as an L-shaped lever may be inserted into the through hole 18 and pulled out from the insertion openings 17, 17.

Next, regarding the side portions of the floor panels 1a, 1a, at approximately the center of one of the opposing frames 4, 4, the supporting portion 8 and the locking portion 12 facing each other at the top and bottom of the frame portion 9 are arranged in advance. , 12 each having a length greater than at least the length of the vertical movement blocking member 3 to form an opening, and after inserting the leg portions 3a, 3a of one or more vertical movement blocking members 3 into the groove 11 from the opening. ,
These vertical movement blocking members 3 are slid to arbitrary positions and aligned so that their respective ends 3b can face and fit into the grooves 11 of the opposing pedestals 4. Then, when the floor panel 1a is pressed against the side of the already fixed floor panel 1a, the end 3b of the vertical movement blocking member 3 fits into the groove 11 of the already fixed pedestal 4. Therefore, in this case, although the vertical movement prevention member 3 cannot connect the frames 4, 4,
When one frame 4 does not move in the vertical direction, the locking parts 12 and 1 that clamp the vertical movement prevention member 3
2 regulates this and prevents misunderstandings between the two.

In addition, when dismantling the temporary floor 1, when the floor panel 1a is pulled in the direction of separating it from the floor panels 1a laid side by side, the end 3b of the vertical movement prevention member 3 will fit into the groove 1.
It can be easily extracted from 1.

Effects of the Invention According to the present invention described above, in the four corners of the floor panel of the temporary floor, the frames are connected to each other via the connecting members to prevent movement in the vertical and horizontal directions, and at the sides In this case, vertical movement is prevented through the frame and the vertical movement prevention member, and it is possible to prevent misalignment of the floor panels and rattling or shifting due to jumping or the like. In addition, these members can be easily attached and removed by on-site workers during construction, resulting in labor-saving temporary construction work and extremely easy construction, removal, and disassembly of the temporary floor.
