Description

  The present invention relates to a detachable attachment structure for an outer wall surface material.

  For example, in an outer wall structure using an outer wall panel, an outer wall surface material such as a ceramic industry is attached to a panel frame that is a base material mounting base, and a face is digged on the outdoor side surface portion of the outer wall surface material, and screws are provided there. It has been hitherto provided that the outer wall surface material is fixed to the panel frame on the back surface side of the face material, the digging portion is filled with putty, and finally finished by painting (touch-up).

  However, with the mounting structure as described above, when replacing the outer wall material due to aging of the outer wall material or design change of the outer wall, after removing the old outer wall panel, a new external In addition to fixing the wall material to the panel frame with screws, it was necessary to perform a construction in which the excavation portion was filled with putty and further touched up, and there was a problem that the construction was very troublesome.

  In view of the problems as described above, it is an object of the present invention to provide a detachable attachment structure for an outer wall surface material that can be easily replaced.

The above problem is that a first mounting hardware is provided between a side edge portion of the outer wall surface material and a base material mounting base such as a frame provided on the back side of the side edge portion. The side edge part of the outer wall surface material is attached to the base material for the face material mounting with hardware,
The first mounting hardware can be operated from the outdoor side through an outer wall joint, and the outer wall surface material can be detached from the surface material mounting base by the operation. This is solved by the detachable mounting structure (first invention).

  In this mounting structure, when the outer wall material is replaced due to the aging of the outer wall material or the design change of the outer wall, the old outer wall material is attached to the face material by operating the first mounting hardware through the outer wall joint. The new outer wall material can be attached to the base material mounting base by operating the first mounting hardware through the outer wall joint, and the putty can be removed from the conventional digging portion. There is no need for embedding, touch-up, etc., and replacement of the outer wall surface material can be performed easily.

  In the above mounting structure, it is preferable that the outer wall surface material can be attached to and detached from the portion attached by the first mounting hardware without moving the outer wall surface material up and down (second invention).

  In this structure, unlike the detachable mounting structure in which the outer wall surface material is kept in a vertical state and hooked up and down, even if there is an obstacle such as an eave heaven above the outer wall surface material. The outer wall surface material can be attached and detached without being obstructed by such an obstacle, and the applicable range can be widened.

As a specific structure that enables the outer wall material to be attached to and detached from the portion attached by the first mounting hardware through the outer wall joint without moving the outer wall material up and down, either the base material mounting base or the outer wall material can be used. The first mounting hardware is attached to either side,

The movable hardware part includes an engaging part and an operating part, and is operated by operating the operating part, whereby the engaging part is engaged and held with the other of the base material mounting base and the outer wall surface material. And can be engaged and released.
It is possible to suitably employ one that allows the operation of the movable hardware part to the operation part through the outer wall joint from the outdoor side (third invention).

In particular, the movable hardware part is pivotally attached to the fixed hardware part so as to be rotatable about an axis perpendicular to the outer wall surface material, and is movable.
The operating portion includes an outer peripheral portion of the arc, and the outer peripheral portion of the arc extends from the side edge portion of the outer wall surface material to the joint side in the rotation operation range between the engaging portion engaging and holding state and the engaging portion engaging and releasing state. It is good to protrude (4th invention).

  In this structure, in the operation of detaching the outer wall surface material, the arc outer peripheral portion protrudes outward from the side edge portion of the outer wall surface material in the rotation operation range between the engagement holding state and the engagement holding release state. Since it will be in a state, the detachment | desorption operation with respect to the operation part through an outer wall joint can be performed easily.

  Further, in this structure, the arc outer peripheral portion of the operation portion may be retained on the back side of the outer wall surface material without protruding from the side edge portion of the outer wall surface material to the joint side in the engagement portion engagement holding state. (5th invention).

  In this case, in the engaged holding state, for example, when a joint material for water stop or joint concealment is installed on the joint on the outer wall, there is no possibility that the operation unit may hinder the joint material installation. In addition, it is possible to eliminate the possibility that the operation unit may hinder the work when the other outer wall surface material sandwiching the joint is performed.

  Further, in the above structure, the outer wall surface material and the base material mounting base are relatively displaced in the out-of-plane direction in the engagement holding state by the engaging portion with the other of the base material mounting base and the outer wall surface material. It is also possible to allow relative slip in the in-plane direction (sixth invention).

  In this case, even when a horizontal force or the like due to an earthquake or the like is applied to the building, stress is hardly generated on the outer wall surface material, and the occurrence of cracking or cracking of the outer wall surface material can be prevented.

In the above structure, the second mounting hardware is provided between the lower end portion of the outer wall surface material and the surface material mounting base provided on the back side of the lower end portion, and the second mounting hardware is used to The lower end of the wall material is attached to the base material mounting base,
The second mounting hardware can be attached to and detached from the base material mounting base by moving the outer wall material up and down in an inclined state so that the upper end portion is on the outdoor side. (7th invention).

  In this case, even if an obstacle such as an eave is present above the outer wall surface material, the outer wall surface material can be attached and detached while being tilted so that its upper end portion is on the outdoor side. Therefore, the outer wall surface material does not interfere with the obstacle, does not hinder the expansion of the application range due to the use of the first mounting hardware, and the outer wall surface material can be easily attached and detached in combination with the first mounting hardware. it can. In particular, the support state of the outer wall surface material can be made firm by the combination with the detachable mounting structure using the first mounting hardware in the sixth invention.

In the above mounting structure, the first mounting hardware is attached to the base material mounting base side, and the outer wall surface material is engaged and held by the first mounting hardware.
A heat insulating material for forming a heat insulating layer is provided between the outer wall surface material and the surface material mounting base,

It is also possible to attach the screw to the face material mounting base with screws such as screws so as to restrict the approach to the face material mounting base with the spacer portion (the eighth invention).

  In other words, a heat insulating material for forming a heat insulating layer is provided between the outer wall surface material and the surface material mounting base, and a main body portion of the first mounting hardware is provided between the heat insulating material and the outer wall surface material. In a structure in which hardware is tightly attached to the base for attaching the face material with screws such as screws, the heat insulation material that forms the heat insulation layer is compressed regardless of whether it is foam or fiber by tightening the screws Although it may be deformed, the first attachment hardware can be firmly attached to the base for attaching the face material by blocking the spacer portion. In addition, since the spacer portion is provided integrally with the first mounting hardware, it is easy to install the spacer and also to easily set the positional relationship between the screw and the spacer.
