Description

Building exterior material fixing device and construction method including insulation function and bit, including insulation function and perforated pipe

The present invention relates to a building exterior material fixing device that allows easy installation of exterior materials made of stone such as marble on the wall of a building, and more particularly, to the exterior wall of a building or a wall of a structure with a stone such as marble, glass, or metal panel. The fixing bracket for installing the finished finishing material can be installed simply and firmly, and at the same time, by installing a condensation prevention cover on the cap of the perforated tube, it is possible to increase the insulation effect by blocking the transmission of external or internal temperature through the perforated tube made of metal. It relates to a building exterior material fixing device and a construction method including a perforated pipe having a thermal insulation function.

In general, when a building is newly constructed or remodeled, marble, glass, metal panels, etc. are used as exterior wall finishing materials of buildings.

In this way, when a rectangular finishing material having a predetermined size is installed on the exterior wall of a building, the insulating material is first installed on the exterior surface, and then a fixing bracket is installed on the exterior surface of the insulation material to install the finishing material made of any one of marble, glass, and metal panel on the exterior surface. Thus, the finishing material is fixed and installed.

In order to fix and install the finishing material as described above, anchor bolts for installing the fixing bracket to the wall where the insulation is installed are installed at regular intervals.

At this time, when installing the fixing bracket, the anchor bolt passes through the insulation to prevent sagging by the finishing materials such as marble, glass, metal panel, etc., and then is installed to be fixed to the concrete wall. .

However, since the outer surface of the wall is covered by the insulating material, if the anchor bolt does not penetrate the wall completely, the anchor bolt may sag. In the process of hitting the bolt, the surrounding insulation material is damaged, so there is a problem in that the fatigue of the wall occurs or the insulation function is deteriorated due to the damage of the insulation material.

Looking at the prior art in this field, the exterior material fixing device for a building and its construction method (hereinafter referred to as "prior art") of Registration Patent Publication No. 10-1541074 (registration date July 27, 2015) are shown in FIG. In the device for fixing the exterior material to the exterior wall (W) of the building to which the insulation (M) is attached as shown, the vertical hole 41 through which the end of the set anchor bolt 10 passes and for fixing the exterior material Angle bracket 40 formed with a horizontal long hole 42; A cylindrical support tube body 50 having a plurality of toothed grooves formed around one end and a locking groove 52 formed at the other end; A ring-type stress distribution plate (60) provided between the angle bracket (40) and the support pipe body (50) and having a bolt through hole (61) through which the end of the set anchor bolt (10) passes in the center; And while rotating the support tube body 50, the other end of the support tube body 50 is inserted to be inserted into the heat insulating material (M) while being formed in a cylindrical shape, and the engaging groove 52 and correspondingly coupled to the inside of the hollow. A configuration comprising; a drill bit having a locking protrusion, a cutter for drilling a ring-shaped hole in the insulating material on one end of the periphery, and a chuck engaging portion 73 for fixing to the rotating shaft of the electric motor at the other end is formed.

In general, the exterior wall of a building is made of an insulating material and a finishing material, and is spaced apart between the insulating material and the finishing material to form a predetermined space to allow air to stay. is to increase

However, the prior art has a problem in that the angle bracket 40, the stress distribution plate 60, and the support pipe body 50 are all made of metal, thereby reducing the thermal insulation effect.

That is, hundreds of anchor bolts, angle brackets, and support pipes are installed to install finishing materials on the exterior wall of the building. There is a problem that air flows into the inside from the outer wall of the building, causing draft and lowering the heating efficiency. Also, in summer, the cooling temperature of the inside is lost through the outer wall, the support pipe, the stress distribution plate, and the angle bracket. There is a problem of dropping the .

In particular, the long hole of the bracket into which the bolt is generally fastened is designed to adjust the width of the gap when the bolt is combined. At the time of initial work, it is positioned to correspond to the width of the finishing material and fixed. There is a problem in that the bolt fastening position in the long hole is changed by external conditions, so that the finishing material is widened or the risk of a safety accident occurs due to separation from the outer wall and falling.

After making the bolt part of the anchor bolt installed on the wall protrude into the second anchor bolt hole of the anti-condensation cover coupled with the lid welded to the perforated tube, insert it into the bolt position fixing hole of the vertical panel, and then fix the bolt position in the bolt part of the anchor bolt coupling a fixing bracket using a washer and a nut;
The horizontal panel of the coupled fixing bracket includes a step of fixing the finishing material by coupling the coupling bolt having a bolt position fixing part having a plurality of locking grooves to the bolt position fixing hole so that the finishing material can be installed by connecting the connecting hardware. A construction method of a building exterior material fixing device including an insulation function and a perforated pipe.
