Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses special clips instead of nails to attach dry exterior wall materials to a frame consisting of main pillars, studs, etc., or to a rim installed on an existing exterior wall. This relates to an outer wall structure that is attached via a.

[Conventional technology]

The exterior wall structure of houses, buildings, etc. using dry-type exterior wall materials generally has a structure in which a rim is placed on the frame and fixed to the rim with nails or the like. In addition, in order to renovate the exterior walls of an existing building or house, ■ a structure in which all the exterior walls are removed and a new wall is formed, ■
A structure in which the existing exterior wall is used as the base and dry-type exterior wall materials are fixed directly to this using nails. ■The exterior wall made of wood and C-shaped channels is fixed on the existing exterior wall with nails and anchor bolts, and dry-type exterior wall materials are fixed to this using nails and anchor bolts. It had a structure in which the exterior wall materials were fixed with nails, screws, etc.

[Problem that the invention seeks to solve]

However, when forming an exterior wall in a new building, in the case of a wooden structure, it is necessary to fix the dry exterior wall material by driving nails, and in the case of a noncombustible structure, it is necessary to fix the dry exterior wall material on the steel frame using screws. As a result, construction efficiency was poor, resulting in a longer construction period and higher costs. In addition, when renovating existing houses,
With structure (2), the cost is enormous, the renovation period is long, and occupancy must be stopped. There were drawbacks such as. Also,
With the structure (2), it is not only difficult to install on concrete and has poor workability, but also has the disadvantages of waterproofing, condensation, corrosion of fixings due to impermeability, and lack of heat insulation. Furthermore, the structure (2) usually uses a C-shaped channel, resulting in high costs and many construction areas.Moreover, the part of the dry-type exterior wall material that comes in contact with the rim is fixed using tufting screws. As a result, there were disadvantages such as poor working efficiency and the need to drill large holes, especially when the material expands due to heat, such as aluminum.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has a back part that is the part of the body rim that contacts the frame or the existing external wall, a side part provided on one side edge of the back part, and a back part provided at the tip of the side part. It consists of a contact surface part provided almost in parallel, and locking parts are formed on the contact surface part at a predetermined pitch according to the width of the dry wall material, and the locking parts are elastically engaged and slid to form a dry wall material. The fixing part of the exterior wall material is supported by a clip made of an elastic material without detachment, and when the dry exterior wall material is supported, the retaining part of the rim is held between the clip's holding piece and the clamping groove, so that it is fixed. This structure significantly shortens the construction period and reduces costs. Furthermore, dry exterior wall materials can be connected at regular intervals, and unlike metal siding materials made of aluminum, they do not deform significantly due to heat. This project proposes an exterior wall structure that can be installed vertically or horizontally without causing any changes to the decorative surface.

〔Effect of the invention〕

As mentioned above, according to the exterior wall structure according to the present invention, the dry exterior wall material is fixed via elastic clips that are easy to install and remove without using nails and slide, so construction time can be significantly shortened. Therefore, costs can be reduced. ■Since the clip elastically locks onto the body rim, it simply presses and engages, and does not come off. ■The clip not only fixes the dry-type exterior wall material, but also functions as a positioning stopper for the dry-type exterior wall material because it is fixed to the rim, making it possible to fix the dry-type exterior wall material without accumulating molding errors. ■Since the structure is fixed to the rim using the elasticity of the clip, it will not bulge due to deformation of the dry-type exterior wall material after construction, and it can prevent the dry-type exterior wall material from separating. ■The rim acts as a raised material, creating a ventilation space between the base and the new exterior wall, providing insulation and preventing condensation. ■Since the torso edge is straight and a clip is secured to it, it can be installed regardless of whether it is stretched vertically or horizontally. It has the following characteristics.
