Abstract

PURPOSE:To enhance the horizontal accuracy in executing a floor panel by placing the floor panel on a panel receipt material, which is detained at the inner side-face of a foundation with an anchor bolt embedded in the foundation. CONSTITUTION:The upper part of an anchor bolt 2 to be embedded in a founda tion 1 is folded at right angles, and the upper threaded portion 21 is protruded horizontally at the inner side-face. Then a floor panel receipt member 3 is put alongside the inner side-face of this foundation 1 and detained with the anchor bolt 2. Floor panel 4 is placed on this panel receipt member 3. Thereby the horizontal accuracy in execution of floor panel 4 is free from influence of the top surface finishing accuracy of the foundation 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor support device for improving the horizontal accuracy of floor panels.

[Conventional technology]

To support the floor panel, as shown in Fig. 6, an anchor bolt 2 buried in the base 1Il11 is protruded from the top surface of the foundation, and an L-shaped mounting bracket 3 placed on the top surface of the foundation is connected to the anchor bolt 2 using the anchor bolt 2. One piece of this mounting bracket 3 is attached to the end face of the floor panel 4, and this is fixed by screwing.

[Problem to be solved by the invention]

In the conventional method of fixing a floor panel to the top surface of a foundation via a mounting bracket, the horizontal accuracy of the floor panel is largely influenced by the accuracy of the top surface of the foundation. Furthermore, if the mounting brackets do not align accurately with the end surface of the floor panel, the strength of the floor panel will be impaired even if the floor panel is secured with screws.

[Means to solve the problem]

The upper part of the anchor bolt to be buried in the foundation is bent at a right angle, and the upper threaded part protrudes horizontally from the inside surface of the foundation.
A floor panel receiving member is aligned with the inner surface of the foundation and is locked with the anchor bolt, and the floor panel is placed on this floor panel receiving member.

[For production]

Since the floor panel support member to be attached to the inside surface of the foundation is fixed to the horizontally protruding anchor bolt with a height of 1a determined in advance on the inside surface of the foundation, the floor panel can be fixed without being affected by the finishing accuracy of the top surface of the foundation. The horizontal accuracy of panel construction can be maintained, and the floor panels can be firmly fixed.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is a foundation built according to the size and plan shape of the building. When pouring concrete for this foundation 1, an anchor bolt 2 with a male thread carved on the outer circumference of the upper end and bent at 90 degrees is buried. At the same time, the upper part 21 of the anchor bolt 2 is made to protrude from the inner surface of the foundation 1 so that the floor panel receiving member can be engaged therewith.

At this time, the upper part 21 of the anchor bolt is at the base fa! The concrete is placed at a predetermined height position, and is protruded and engaged with an inner formwork (not shown).

Reference numeral 3 denotes a floor panel support member which is attached to the inner surface of the foundation 1 and fixed by screwing the nut 5 with the upper part 21 of the anchor bolt 2. The floor panel support member 3 may be a member having an L-shaped cross section, for example. Use channels etc. A bolt insertion hole 31H passing through the upper part 21 of the anchor bolt 2 is formed in the vertical piece 31 of the floor panel receiving member 3 when it is installed.
There is a hole 32H for fixing the floor panel on the other piece 32 that is horizontal during installation.
are drilled in each.

The other piece 32 of the floor panel support member 3, which is fixed to the inner surface of the foundation 1 in this way, is installed horizontally,
The bottom surface of the end of the floor panel 4 is placed on this piece 31 so that the bottom surface of the end thereof is drawn against it, and the bolt 6 is inserted between the hole 32H and the frame of the floor panel 4, and the nut 7 is screwed into the bolt 6 to fix it.

Therefore, when the floor panel 4 is fixed using this method, the floor panel support member 3 can be supported while maintaining horizontal accuracy without being affected by the finishing accuracy of the top surface of the foundation.

Even if this floor panel 4 is supported only at its ends, it has the strength as a floor itself.

On the other hand, when the floor panel 4 needs to be supported at multiple locations from its lower surface due to its strength, for example, in the case of a honeycomb-structured floor panel, the angled floor panel support member 3 supports the floor panel while maintaining the required strength. Can not. In such a case, support is provided by the method shown in FIGS. 3 to 5. In this case, instead of the L-shaped angle member, a long floor panel support beam 8 is erected between the upper parts 21, 21 of the anchor bolts that respectively protrude inside the opposing foundations 1.1. This floor panel support beam 8 has a cutout groove 81 formed on the lower surface of both ends into which the anchor bolt upper part 21 is fitted, and a notch is cut in the cutout groove 81 so that a nut (not shown) can be screwed into the anchor bolt upper part. A groove 81 is formed with a conductive element 682. The load applied to the floor panel placed on the floor panel support beam 8 is averaged over the entire length of the floor panel support beam 8 to support it. In this method as well, the floor panel can be supported while maintaining its horizontal accuracy regardless of the finishing accuracy of the top surface of the foundation.

〔Effect of the invention〕

The floor support device of the present invention bends the upper part at right angles, makes this upper threaded part protrude horizontally from the inner surface of the foundation, and locks the floor panel support member aligned with the inner surface of the foundation. Since the floor panel is placed on the member, the floor panel can be supported with the required horizontal accuracy regardless of the top surface finishing accuracy of the foundation, and the horizontal accuracy of the floor panel is improved.
