Description

Anchor bolt for preventing sag {Anchor Volt}

The anchor bolt of the present invention protects the anchor bolt from being broken by preventing the entrance of the anchor bolt from being damaged during the process of inserting the anchor bolt into the engaging hole after inserting the engaging hole into the wall, To an anchor bolt for preventing sagging.

Generally, anchor bolt set is used for fixing structures and the like, and is widely used throughout industrial society including buildings, bridges, railroad, roads, and infrastructure construction. Such anchor bolts are used not only for fixing the structure but also for various purposes such as connecting structures and the like.

Particularly, although the anchor bolt set is used to more securely fix the structure to the wall, the anchor bolt set is frequently loosened due to vibration, fatigue, or the like, and the original function is lost.

The conventional anchor bolt set is largely composed of an anchor bolt, a sleeve, a flat washer, a spring washer, and a nut. The anchor bolt has a screw part formed in a part of an outer circumferential surface thereof, Is formed.

The sleeve is formed into a tubular shape so that the anchor bolt is inserted therein, and a plurality of incision pieces are formed at an end portion contacting the tapered extension portion.

Therefore, in the conventional anchor bolt assembly, an anchor bolt is inserted together with a sleeve in a coupling hole formed in a wall, and then the structure is coupled with the flat washer and the spring washer, and finally the nut is fastened to fix the building to the wall.

That is, when the nut is fastened to the anchor bolt, the anchor bolt moves to the outside of the wall to tighten the structure.

Therefore, the sleeve coupled to the anchor bolt can not move to the outside of the wall by the structure, and the incision is expanded along the inclined surface of the extension part of the anchor bolt and is pressed to the wall side, thereby fixing the structure to the wall.

In such a conventional anchor bolt set, a certain gap is formed between the threaded portion of the anchor bolt and the inner circumferential surface of the sleeve. This gap acts as a factor for moving the anchor bolt when vibrations of the wall, structure or fatigue of the anchor bolt occur. Thereby causing deflection phenomenon.

In addition, in the process of drilling the hole for joining the anchor bolt to the wall, the periphery of the hole of the hole located on the surface of the wall is damaged, and the entrance of the hole is further damaged due to the process of tightening the anchor bolt There is a problem that the sagging phenomenon becomes serious

Accordingly, since the sleeve is loosened by the movement of the anchor bolt, the structure is poorly fixed, and the structure that is fixed in such a manner becomes detached from the installed position or becomes unstable. In case of severe accident, It had many problems to be developed.

In order to overcome such deflection phenomenon, Korean Patent Application No. 10-2015-0131421 entitled " Fixing structure of building exterior material using an integrated three-anchor and method of construction thereof "

The above-mentioned first-filed patent is closely attached to a hole of a building without a clearance

An outer body portion protruding out of the hole of the building; and an upper body fixed to the upper body by rotating the upper body, There is an effect of preventing a sagging phenomenon due to a gap generated between the engaging hole and the outer body portion by using a monolithic set anchor formed of a polygonal rotary fixing portion supporting in the horizontal direction and a screw portion fixing the upper fixing portion , There is no portion for supporting the outer body portion at the entrance of the fitting hole because the friction sleeve and the rotation fixing portion are located in front of the fitting hole. Therefore, when the fitting body is provided in the anchor, the load of the structure is externally projected There is a problem that the joint hole entrance is broken due to concentrated sagging phenomenon.

Korean Patent Application No. 2015-59838 "Building Panel Fixing Device" is an apparatus for fixing a building panel, which is constructed by inserting an engaging hole into a wall of a building and then inserting an inner surface of the first supporting frame, There is a spacing space between the outer surfaces of the first support and a fixing device is formed by a method including a filling material located in the spacing space.

Also, in the conventional anchor bolt as described above, the anchor bolt is inserted into the wall, and then the sleeve is pressed and fixed to the coupling hole. Then, in the process of installing the structure bracket on the anchor bolt projected to the outside of the coupling hole, There is a problem in that the anchor bolt is loosened in the engaging hole to cause a deflection phenomenon.

Meanwhile, due to the revised construction law of January 1, 2016, the thickness of insulation has been further strengthened.

Therefore, since the thickness is much thicker than the thickness of the existing insulation, more load is applied to the anchor bolt, causing sagging. Therefore, to prevent sagging, use larger anchor bolts or use ancillary means It is also used.

However, recently, newly constructed buildings are constructed by closely arranging reinforcing bars on the wall due to reinforcement of building method. Therefore, when using an anchor bolt having a large size, it is not easy to drill a hole between reinforcing bars and reinforcing bars, The reinforcing bars may be damaged and affect the stability of the building.

Therefore, the size of the anchor bolt requires the same size as that of the conventional one, and it requires anchor bolt to prevent sagging by supporting more load due to the thickness change of the insulating material.
