Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a joint structure between wooden floor panels that make up the floor of a building, and more specifically to a joint fixed to the upper end surface of a precast concrete wall panel. This invention relates to a structure in which wooden floor panels arranged abutting each other are joined together via metal fittings.

<Prior art> Various mounting hardware and structures have been proposed to be used when constructing a floor surface by laying floor panels, but in all cases, the floor panels and wall panels are made of the same material, for example, the same wood. Warm with panels,
Also, many of them are made of precast concrete.

Therefore, if the lower floor wall panel and the upper floor wall panel are tightened by interposing the floor panel with so-called bolts, the floor panels can be fixed to each other and the floor panel and the wall panel can be tightened at the same time. It was something that could be done.

However, when the floor panel is made of wood and the wall panel is made of precast concrete, the bolts must be placed in the wall panel in advance, and the floor panels must be placed butt against each other. It is difficult to tighten this barrel bolt in this condition. For this reason, the applicant first used a substantially U-shaped joining hardware to clamp the ends of the floor panel with this hardware, and then tightly connected the upper and lower floor wall panels to the floor panel through this joining hardware with bolts, etc. We proposed a structure that could withstand both vertical and horizontal loads.
58-23977, Utility Model Application Publication No. 59-131401).

According to this mounting structure, the rigidity is satisfactory despite the partial arrangement of the metal fittings.

<Problem to be solved by the invention> However, the above-mentioned mounting structure cannot sufficiently fix and tighten the floor panels at the parts where they are placed abutting each other. The surface was uneven.

<Means for Solving the Problems> The present invention is a joint structure made to solve the above problems, in which a wooden floor panel is connected via a joint hardware fixed to the upper end surface of a precast concrete wall panel In a structure in which they are joined by butting each other, there is a receiving part that is approximately L-shaped in side view by a vertical receiving piece and a horizontal receiving piece that is substantially perpendicular to the vertical receiving piece, and a receiving part that is located at the center of the lower part of the vertical receiving piece and is connected to the horizontal receiving piece. Notched on the opposite side,
The horizontal support piece and a fixing part extending substantially in the same plane form a joining hardware, and the fixing part of the joining hardware is screwed to the upper end surface of the wall panel via a fixing bolt, and the butt Each side end face of each of the floor panels arranged in a mating manner is nailed to the vertical support piece, and the lower end face of each floor panel and the horizontal support piece are respectively nailed together.

<Example> Hereinafter, the joining structure of the present invention will be explained in detail based on the drawings.

FIG. 1 is a perspective view of a joining hardware 1 used in the joining structure of the present invention.

The joining hardware 1 consists of a receiving part 11 and a fixing part 12.
The receiving portion 11 is formed into a substantially L-shape in side view from a vertical receiving piece 11a that stands vertically and a horizontal receiving piece 11b that extends perpendicularly to the vertical receiving piece 11a in a so-called horizontal state.

On the other hand, the fixing portion 12 extends in the opposite direction to the horizontal receiving piece 11b so as to be orthogonal to the vertical receiving piece 11a. Usually, the fixing part 12 is the vertical receiving piece 1
The center of the lower part of 1a is cut out toward the opposite side of the horizontal support piece 11b, and the cutout piece is connected to the horizontal support piece 11b.
It is formed in a state that extends substantially in the same plane as the.

Note that the vertical support piece 11a and the horizontal support piece 11b are each provided with a required number of nail holes na, na..., nb, nb..., and bolt insertion holes 13a are provided in the fixing part 12 at predetermined intervals. , 13b are perforated.

FIG. 2 shows a state in which wooden floor panels (simply referred to as floor panels) 21 and 22 are placed on the upper end surface 31 of a precast concrete wall panel (simply referred to as wall panels) 3 using the joining hardware 1 and are fastened together. FIG.

First, the fixing portion 12 of the joining hardware 1 is brought into contact with the embedded hardware 32 provided on the upper end surface 31 of the wall panel 3. Bolt holes 32a, 3 are pre-filled in the embedded metal fittings 32.
2b are provided, and the bolt holes 32a, 32b are provided at the same spacing as the insertion holes 13a, 13b bored in the fixing part 12, so the insertion holes 13a, 13b communicate with the bolt holes 32a, 32b. .

Therefore, the fixing bolts 4a, 4b are inserted into the through holes 13a,
13b, and bolt hole 32 of embedded metal fitting 32.
a, 32b.

Therefore, even if the fixing bolts 4a and 4b protrude onto the upper end surface 31 of the wall panel 3, the fixing portion 12 does not fit into the receiving portion 1.
1 (vertical support piece 11a), it does not interfere with fixing the floor panels 21, 22 and enables sufficient fastening.

Next, the floor panels 21 and 22 are sequentially placed on the joining hardware 1 according to the laying procedure for each floor panel. As described above, the joint metal fitting 1 is formed with a receiving part 11 having a substantially L-shaped cross section, and the floor panels 21 and 22 are placed on this receiving part 11 in abutted state.

More specifically, the vertical support piece 11a is brought into contact with the side end faces 21a and 22a of the floor panels 21 and 22 in a straddling state, and the lower end faces 21b and 22b of each unit floor panel are brought into contact with the horizontal support piece 11b. Place it astride.

In such a state, the nail hole of the vertical support piece 11a
Nails are driven into the side end surfaces 21a and 22b via na, na, . . .

Furthermore, nail holes nb, nb... from the horizontal receiving piece 11b...
Drive the nail through.

That is, as shown in the longitudinal sectional view of the main part in FIG. 3, the side end surfaces 21a and 22b of the floor panels 21 and 22 are integrally nailed to the vertical support piece 11a, and the lower end surfaces 21a and 22a are also nailed to the horizontal support piece 11a. It is nailed through piece 11b. As a result, the floor panels 21 and 2
2 are mutual on the wall panel 3 and the wall panel 3
and are integrally tied together.

As a result of the above, the floor panels 21 and 22 are integrally connected to each other in the receiving part 11 of the joining hardware 1, and the integrally connected floor panels 21 and 22 are then placed on the wall panel 3 via the fixing part 12. It will be fixed on the end face 31.

<Effect> In this way, the wooden floor panel can be fastened and fixed on the precast concrete wall panel with high rigidity without using bolts. or,
This prevents the floor panels from ``unruling'' and prevents not only uneven floors, but also floor rumbling and floor vibrations.

Moreover, since the joining hardware itself used in the present invention has an extremely simple shape, the construction is simple and the joining structure is low cost.
