埋設されているものである。In order to solve the above-mentioned problems, a slab structure according to the present invention is a slab in which mortar is filled in joints of a plurality of panels laid on a floor mounting portion or a roof mounting portion of a building. In the structure, the width of the joint portion is made smaller at the entrance portion than at the inside, and the receiving bracket is attached to the floor mounting portion or the roof mounting portion near the corner of the panel,
A reinforcing bar having an end attached to the receiving fitting is buried halfway in the joint.

It is possible to bear the shearing force by engaging with each other, and to distribute the force acting in the out-of-plane direction of the panel to each panel. In addition, a reinforcing bar whose end is attached to the metal fittings attached to the floor mounting part or the roof mounting part near the corner of the panel is buried halfway through the joint, so the panel is mounted near the corner via the metal fitting. Is fixed by the reinforcing bar fixed to the mounting portion.

It is preferable that the cut end is attached to the attachment hole of the receiving fitting. By configuring the slab structure in this way, the degree of freedom in setting the position of the rebar axis relative to the mounting hole of the receiving bracket is improved, and accordingly, the axis of the rebar coincides with the center of the joint. And the function of pressing down the reinforcing bar panel can be sufficiently exhibited.

A plurality of panels 1 are arranged in rows and columns on beams 2 serving as floor mounting portions or roof mounting portions, and joint portions 3 are formed between adjacent panels 1. A receiving bracket 4 is attached to the panel 1 located at the corner of the laid-out plane and the beam 2 near the corner of the panel 1 arranged at a predetermined position in the row direction. A reinforcing bar 5 having a length that can be buried halfway into the joint 3 is attached to the metal fitting 4, and the joint 3 is filled with mortar 6. Note that a plurality of types of receiving fittings are used as described later. However, when the shape of the receiving fitting does not matter, the receiving fitting 4 is typically used.

いる。Panel 1 is made of lightweight cellular concrete (AL
C) It is composed of a panel such as a panel or a PC panel, and at least both ends in the longitudinal direction are placed on the beam 2 and laid in the width direction (row direction) and the longitudinal direction (column direction) of the panel 1.

れている。Steps 1a for forming joint portions 3 over the entire length are provided on both sides (long sides) in the width direction of each panel 1.
As shown in FIGS. 4A to 4C, the stepped portion 1a formed on the adjacent panel 1 is larger than the entrance portion 3a of the joint portion 3 on the front surface side of the panel 1. The joint portion 3 has a shape such that the inside of the joint portion 3 that has entered the thickness direction of the panel 1 has a larger width dimension.

By facing such steps 1a, a dovetailed joint 3 is formed. FIG. 2B shows one panel 1.
Has a hook-shaped step 1a, and the other panel 1 has a right-angled step 1a. Even in the joint portion 3 thus formed, the inner portion 3 is larger than the width of the entrance portion 3a.
The width dimension of b is formed larger. In FIG. 3C, a stepped portion 1a having a “U” shape is formed on both of the adjacent panels 1, and a hexagonal bar-shaped joint portion 3 is formed by opposing such a stepped portion 1a. .

担することが可能である。As described above, by filling the mortar 6 into the joint 3 formed with the width of the inside 3b larger than the width of the inlet 3a, the depth of the step 1a in the joint 3 is increased. It is possible to receive shearing force in an area corresponding to the length and length. Therefore, when an out-of-plane force acts on the panel 1, the force is transmitted to the adjacent panel 1 via the mortar 6 filled in the step portion 1 a and the joint portion 3 of the panel 1. That is, it is possible to transmit and bear the force in the floating direction of the panel 1.

目地部３ｃの必要長さを設定することが可能である。The steps 1a on both sides in the width direction of the panel 1 can be formed by cutting. In particular, since the joint 3 (the enlarged joint 3c) having a larger width in the inside 3b than the inlet 3a transmits the shearing force, the force in the floating direction acting on the panel 1 is transmitted to the adjacent panel. The required length of the enlarged joint 3c can be set by assuming the force in the floating direction.

The enlarged joint portion 3c may be formed by the amount. In this case, the other part of the joint part 3 may be a normal joint part 3 formed at a right angle in the thickness direction.

The end of the reinforcing bar 5 is attached to the receiving bracket 4 and is buried halfway in the joint 3. For this reason, as shown in FIG. 6, the length is formed sufficiently shorter than half the length of the panel 1, and the end is curved from the axis 5 b of the straight portion 5 a of the reinforcing bar 5 in the lateral direction. 5c is formed, and then formed into a hook shape having an extension 5e that is bent in the original direction and the tip 5d extends to the opposite side of the axis 5b. For this reason, the axis 5b in the straight portion 5a and the axis 5b in the curved portion 5c are separated by a predetermined distance.

The length of the extension 5e is about 35 mm, and the distance between the axis 5b of the straight section 5a and the axis 5b of the bending section 5c is about 17 mm.
is set to mm. Therefore, the extension of the axis 5b of the straight portion 5a intersects with the extension 5e.

A receiving bracket 4 is arranged near the other end of the panel 1 and fixed to the beam 2. In addition, a panel 2 for a waist wall (not shown), an angle material serving as a member for receiving mortar, and the like are fixed to the beam 2 so as to face the panel 1 disposed on the end side of the slab.

Attached. Thus, the position of the linear portion 5a with respect to the step portion 1a of the panel 1 is adjusted by appropriately adjusting the attachment depth of the extension portion 5e with respect to the attachment holes 10c, 4c. It is possible.

The curved portion 5c of the reinforcing bar 5 is inserted and attached to d, and the straight portion 5a is arranged at the joint 3 (enlarged joint 3c). In particular, it is preferable that the reinforcing bar 5 disposed in the joint 3 is located substantially at the center of the joint 3 from the viewpoint of strength. Therefore, the extension 8 e of the reinforcing bar 5 receives the metal fitting 8.
By adjusting the insertion depth when the straight portion 5a is inserted into the mounting hole 5d, the position of the linear portion 5a at the joint 3 can be easily adjusted.

を押さえつけることが出来る。As described in detail above, in the slab structure according to the present invention, the joint formed between the laid panels is formed so that the entrance is smaller than the inside, and the joint is formed halfway through the joint. Since the reinforcing bar is buried, the panel can be pressed down by the reinforcing bar, the floor mounting portion, the metal fittings and the reinforcing bar mounted on the roof mounting portion.

要する材料コストを削減することが出来る。For this reason, even if a force in the floating direction due to blowing up in a strong wind acts on the slab, the force can be transmitted to the adjacent panel via the mortar filled in the joint portion and borne. Since the end of the panel is pressed against the mounting portion by the reinforcing bar, it does not float. Further, since the reinforcing bar is not buried over the entire length of the joint, and is only a portion corresponding to the vicinity of the end of the panel, the material cost required for the reinforcing bar can be reduced.

位置を適宜調整することが出来る。The end of the reinforcing bar is not simply formed in an L-shape, but is bent once from the axis and then bent further to extend the tip to the opposite side of the curved portion. When inserted into the mounting hole of the metal fitting, the insertion depth can be appropriately set. For this reason, the axial position of the reinforcing bar with respect to the joint can be appropriately adjusted.
