Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a floor mounting structure in which panels such as lightweight cellular concrete (hereinafter referred to as ALC) are laid in parallel on wooden beams.

[0002]

2. Description of the Related Art Conventionally, a building using an ALC plate is generally made of a steel frame in order to have a fire-resistant structure. The joints of the panel facing in the longitudinal direction are laid in a straight line with the both ends suspended, and the groove provided on the upper surface of the joint adjacent to the width direction of the panel is opposed to the groove in the longitudinal direction. The grooves are connected by mortar with embedded joint reinforcement. The joint reinforcing bar has its lower end welded to the upper flange surface of the beam, is supported in a state where it penetrates a through hole formed in the upper end of a plate-shaped mounting bracket, and is fixed to the beam.

Recently, a fire-resistant building using wooden beams has been studied. In this case, welding cannot be performed, so that a conventional mounting bracket cannot be used, and a new mounting structure has been developed. It has been demanded. As described in Japanese Utility Model Application Laid-Open No. 61-13704, a screw having an annular portion at the head portion at the joint of the joint groove of the adjacent panel is screwed into the wooden beam as a wooden beam floor structure. A method has been proposed in which a joint reinforcing bar is inserted into an annular portion and then the joint groove is filled with mortar. However, in order to screw in this screw,
Special tools were required, and it was difficult to maintain the joint reinforcement horizontally.

[0004]

SUMMARY OF THE INVENTION The present invention provides a wooden beam floor structure which does not require a special tool, can easily maintain a joint reinforcing bar horizontally, and can fix a panel.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention solves the above-mentioned problem by arranging the panels in parallel in a state where both ends in the longitudinal direction are suspended on a wooden beam, and joining both panels of joints adjacent in the width direction. A groove is provided on the upper surface, and the joints of the panels facing each other in the longitudinal direction are aligned, and in a floor panel mounting structure in which joints are connected by mortar in which joint reinforcing bars are embedded, a cross section of the joint reinforcing bars is A mounting bracket having a right-angled bent surface such as a letter or L is inserted into and supported by a vertical through-hole or notch in a vertical surface, and the horizontal surface of the mounting bracket presses the bottom surface of the groove to fix the panel. Thus, the metal fitting is screwed to the wooden beam with a screw bolt.

[0006]

According to the invention, no special tool is required because the screw bolt is used for mounting the metal fitting, and the joint reinforcing steel is inserted into the same level of the through hole of the parallel vertical surface of the metal fitting having a U-shaped cross section. If supported, the rebar can be kept horizontal. Further, since the groove of the panel is pressed and fixed from above on the horizontal surface of the metal fitting, the panel can be fixed to some extent before the mortar solidifies, so that the workability can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view of the floor structure of the present invention, FIG. 2 is a cross-sectional view of the AA plane in FIG. 1, and FIGS. 3 to 6 are perspective views of mounting hardware. Both ends in the longitudinal direction of the panel 1 are juxtaposed in a state of being suspended by a wooden beam 2, and grooves 3 are provided on the upper surfaces of both panels of joints adjacent in the width direction, so that the panels 1 opposed in the longitudinal direction are provided. And the groove 3a of the panel 1a are laid in a straight line. At the connection between the groove 3 and the groove 3a, a fitting 5 to which a joint reinforcing bar 4 is engaged is provided, and is connected in a state of being buried in a mortar. The joints 6 in the longitudinal direction are also filled with mortar. (The mortar is not shown)

[0008] The mounting bracket 5 for the joint reinforcing bar 4 is shown in FIG.
The cross-section has a U-shape, and the parallel vertical surfaces 5b have the same level, and the through holes 5c having a diameter slightly larger than the diameter of the reinforcing bar 4 are provided.
Is provided, and a through hole 5d is formed in the horizontal surface 5a. The metal fittings 5 are disposed so as to straddle the grooves 3 and 3a of the connecting portion of the four panels adjacent to each other in the width direction and the longitudinal direction, and penetrate through the through hole 5d in the horizontal plane so that the screw bolt 7 is formed.
Are screwed to the wooden beam 2 via joints 6, and press and fix the grooves 3 and 3a of the panel from above. The joint reinforcing bar 4 is horizontally inserted and supported in the through holes 5b, 5b on the vertical surface of the metal fitting 5.

FIG. 4 shows an example in which a notch 5e is provided on the vertical surface 5b of the mounting bracket 5, and when a long reinforcing bar is supported, it is convenient because it only has to be fitted from the side. FIG.
Is an example in which the cross section of the metal fitting 5 is L-shaped and can be used in the same manner. In this case, the joint reinforcing bar 4 is
By arranging over the entire length of 1a or arranging a spacer at one end of the reinforcing bar, the reinforcing bar can be kept horizontal. The present invention can be applied not only to a horizontal floor structure but also to a roof structure.

The metal fitting 5 shown in FIG. 6 has a shape obtained by combining two sets of L shapes. As shown in FIG. 7, the floor panel 1 facing the wall surface 9 is fixed to the beam 2 carried on the column 8 with the screw bolt 7. Sometimes used. In this way, the mortar is filled in the gaps between the joints and the wall surfaces of the panels laid adjacent to each other, so that an integral strong floor is formed.

[0011]

As described above in detail, according to the present invention, no special tool is required because the screw bolt is used for fixing the mounting bracket of the floor panel, and the parallel mounting of the U-shaped cross section is not required. If the joint reinforcement is inserted and supported in the same level of perforations on a vertical surface, the reinforcement can be kept horizontal. Further, since the panel groove is pressed and fixed from above on the horizontal surface of the metal fitting, excellent workability can be obtained such that the panel can be fixed to some extent before the mortar solidifies. The mortar is filled in the gaps between the joints and the wall surfaces of the panels laid next to each other, so that an integral strong floor is formed.
