Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a dry outer wall on a frame made up of main columns, studs, etc. at the time of new construction, or on a furring strip arranged on an existing outer wall at the time of repair. The present invention relates to an outer wall structure in which a material is attached via a special clip instead of a nail.

[Conventional technology]

The outer wall structure of houses and structures using dry type outer wall materials is generally a structure in which a furring strip is arranged on a frame and fixed to the furring strip with a nail or the like. In addition, in order to repair the outer walls of existing buildings and existing houses, all the outer walls were removed and new walls were formed,
A structure in which an existing outer wall is used as a base, and a dry outer wall material is directly fixed to this with nails. A wooden furring strip, a furring strip made of C-shaped channels is fixed to the existing outer wall with nails and anchor bolts. The material was either nailed or fixed with screws.

[Problems to be solved by the invention]

However, when forming an outer wall in a new construction, it is necessary to fix the dry outer wall material by driving nails in the case of wooden construction, and in the non-combustible structure, the dry outer wall material is fixed on the furring strip made of steel with screw screws. Therefore, the construction efficiency is poor, and as a result, there is a disadvantage that the cost is increased due to the extension of the construction period. In addition, when renovating an existing house, the cost of the structure is enormous, the renovation period is long, and the residence must be stopped. There were drawbacks such as. Further, the structure of (3) is not only difficult to apply to concrete or the like and is inferior in workability, but also has disadvantages such as waterproofness, dew condensation, corrosion of a fixture due to impermeability, and lack of heat insulation. further,
In this structure, the C-shaped channel is usually used, so that the cost is high and there are many places to be constructed. Moreover, the dry outer wall material is fixed by tapping screws at the portion that contacts the furring strip.
As a result, the work efficiency is low, and there is a disadvantage that it is necessary to form a large fool hole especially when the expansion due to heat is large like aluminum.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has a back portion, which is a portion where the furring strip is in contact with a skeleton or an existing outer wall, a side surface portion provided at one side edge of the back surface portion, and a back surface portion at the tip of the side surface portion. The contact surface portion is provided substantially parallel to the contact surface portion, and the contact surface portion is formed with a groove portion and a locking hole for fixing the clip at a predetermined pitch according to the width of the dry outer wall material. Fix the fixed part of the dry type outer wall material without sliding by inserting the sandwiching groove into the groove so that the back surface of the clip whose cross section is almost S-shaped from the mating groove comes to the back surface of the contact surface of the furring strip. In addition, the clip is fixed by locking the locking piece provided on the back surface of the clip with the locking hole,
The construction period can be significantly shortened to reduce costs, and the dry outer wall materials can be connected at regular intervals.
This is to propose a vertical and horizontal free outer wall structure that can be mounted so that the decorative surface does not change even if it is largely deformed by heat like a metal siding material made of aluminum.
