Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure for fixing an exterior plate to a concrete plate forming a building frame.

<Prior art> Structures for fixing exterior plates such as ceramic tiles to concrete plates, which are the building frame, include a method of attaching them with a binder such as mortar between the exterior plate and the building frame, and a method of attaching the exterior plates to the building frame using a binder such as mortar. There is a construction method in which exterior panels are fixed using metal fittings that are arranged vertically and horizontally and attached to the crosspieces.

<Problems to be solved by the invention> However, in the former construction method, the so-called wet construction method, the installation strength becomes unstable and requires a lot of construction time for hardening and curing. In the latter method, the so-called dry method,
Because the crosspieces and mounting hardware are interposed between the building frame and the exterior panels, more gaps than necessary are formed, which adversely affects the installation strength and is not desirable in terms of appearance.

<Means for solving the problem> The present invention was devised to solve the above problem, and includes a pair of gripping bodies having claw pieces that are clamped with bolts to grip the back side of the exterior plate. An anchor body previously arranged between these gripping bodies is fixed in a concrete plate.

<Function> In other words, the claw piece is gripped between the retaining grooves provided on the back surface of the exterior plate, and the anchor body disposed between both gripping bodies is fixed in the concrete plate.
Since the exterior plate itself is in close proximity to the building frame and the anchor body is fixed integrally with the concrete plate, sufficient mounting strength can be obtained. In particular, since the pair of gripping bodies and the anchor body disposed between them form a so-called three-piece configuration, each of them moves independently, and therefore external stress from the concrete plate is concentrated on the anchor body. The stress is also distributed all the way down to the claws of the gripping body, so that stress is not directly applied and the exterior plate will not be damaged.

<Example> The fixing structure of the building exterior board of the present invention will be described in detail below based on the drawings.

FIG. 1 is an exploded perspective view of fixing hardware A used in the fixing structure. The fixing hardware A has a pair of gripping bodies 1, 1, and an anchor body 2 provided therebetween, and these gripping bodies 1, anchor body 2, and gripping body 1 are connected by bolts v. Grip body 1 is horizontal side 1
A claw piece 12 is formed on the outer end of one gripper 1, and a screw hole 13 is provided in one gripper 1 to be screwed into a threaded portion Va of a bolt v. On the other hand, claw pieces 12 are similarly formed on the other gripping body 1, and through holes 14, 14 are bored therein. Anchor body 2 has a mark (Q) on the bottom end.
A shaped mounting portion 21 and a bent portion 22 bent substantially orthogonally in different directions are formed at the upper end, and through holes 23 and 24 are formed in the mounting portion 21. The fixing hardware A has a symmetrical shape around the bolt v and the anchor body 2, and as will be described later, when it is fixed to the concrete body, the anchor body 2
The external stress from is distributed to each gripper 1, 1.

In the fixing hardware A having such a structure, the bolt v is inserted into the through hole 14 of the grip body 1 and the through holes 23 and 24 of the anchor body 2, and the screw portion Va is screwed into the screw hole 13. Then, when the bolt v is rotated in a predetermined direction, both the gripping bodies 1, 1 come close to each other, and are in a state where they press the back surface of the so-called exterior plate. That is, the claw pieces 12, 12 grip between the locking grooves provided in the exterior plate, which will be described later.

FIG. 2 shows another embodiment of the fixing hardware A. In this fixing hardware A, the anchor body 3 is formed of a rod-shaped body, and the mounting portion 31 has a bolt v as described above.
A shaped bent portion 32 is formed at the tip.

The fixing hardware A is held at the four corners of the ceramic plate 4, which is one of the exterior plates, and the anchor bodies 2 and 3 are fixed to the concrete plate 5 as shown in FIG. Four latching grooves (not shown) usually provided on the back side of the ceramic plate 4
The gaps are held by four fixing metal fittings A, A, A, and A, and the mold is laid in such a manner that predetermined joints M are formed on the bottom surface of the mold. Next, thin reinforcing bars 6 are assembled and placed on top of them. Also, due to the weight of the fine reinforcing bars 6, the ceramic plates 4, 4...
In order to avoid damage to the reinforcing bars 6, the thin reinforcing bars 6 themselves are placed in a suspended state without using a support. Furthermore, the fixing hardware A is covered with resin mortar 7, leaving the anchor parts 2 and 3.
Cover with water.

In such a state, concrete is poured into the formwork to create a concrete plate. Examples of the concrete board 5 include an ALC board, a PC board, and even a hollow cement board.

Due to the above construction, the ceramic plates 4, 4... are fixed to the fixing hardware A,
It is securely gripped through the bending part 2.
Due to the anchoring effect of 2,32, the anchor body 2,
3 is fixed in the ALC board, PC board, and hollow cement board. In other words, this on ceramic plates 4, 4...
It has a structure that is integrated with ALC board, PC board, and hollow cement board. Moreover, since the fixing hardware A itself is covered with the highly elastic resin mortar 7,
Independent movability of the three pieces is maintained by the so-called pair of gripping bodies 1, 1 and anchor bodies 2, 3. As a result, even if stress is applied from the concrete plate 5 to the anchor bodies 2, 3, it is dispersed and the claw pieces 1 of the gripping bodies 1, 1
No large stress is applied to 2 and 12, and the ceramic plate 4 will not be damaged.

FIG. 4 is a schematic front view showing the ceramic plates 4, 4... arranged on the surface of the concrete plate 5 by the above construction. Between these ceramic plates 4, 4..., joints M are formed in an orderly manner when laid in the formwork. After the concrete plates 5 are cured and hardened, when used as a building frame, as shown in FIG. Furthermore, a gasket G is arranged to ensure rain protection between both concrete plates 5, 5.

<Effects> According to the above anchoring structure, the exterior plate can be attached to the concrete plate with sufficient strength, and the anchorage hardware does not concentrate stress from the concrete plate on the exterior plate, so damage to the exterior plate itself is avoided. This results in an extremely suitable fixing structure for the exterior plate.
