Description

Construction method of anchor assembly for installing exterior material including insulation of concrete wall {omit}

The present invention relates to a method of constructing an anchor assembly for fixing an exterior material such as terracotta and marble to a concrete wall after installing a heat insulating material on a concrete wall. More particularly, the present invention relates to an anchor assembly for preventing anchor bolt from sagging, And more particularly, to a method of installing an anchor assembly for installing an exterior material including a heat insulating material of a concrete wall to effectively prevent anchor bolt from being detached when a nut is tightened.

Generally, a curtain wall made of inner and outer panels of tiles, terracotta, marble, etc. is installed in a prefabricated manner to decorate the inner wall or outer wall of a concrete structure. Between the wall surface of the building and the curtain wall, a foam insulation material such as polyurethane foam or styrofoam is installed to insulate the inside of the building.

Especially, as the exterior material, since the weight of marble is large, it should be done without sag due to its own weight. Marble is usually installed through anchor bolts. That is, the anchor bolts are inserted into the holes of the concrete wall, and brackets (or angles) are assembled to the anchor bolts. In this case, since the weight of the marble is transferred to the anchor bolt, the anchor bolt should be free from sagging, and the anchor bolt should not be detached from the tightening force of the nut fixing the bracket.

As a background of the present invention, Korean Registered Patent No. 10-1147446 discloses an angle for installing a thermal insulation material and a method for installing a thermal insulation material using the angle. In the above background art, the anchor bolt is inserted into the concrete wall, the main body of the U-shaped fastener is inserted into the threaded portion of the anchor bolt and inserted into the heat insulating material, and then the fastening member is fastened with the nut and connected to the fastener body.

However, in the background art, there is a problem that the remaining part of the anchor bolt except the expansion cap is spaced apart from the wall hole, and the anchor bolt is bent downward due to the weight of the marble.

In addition, if the nut is strongly tightened, there is no part for catching the anchor bolt, so there is a serious problem that the anchor bolt is pulled out and out.

In other words, when tightening the anchor bolt with the nut, it is necessary to support the rear end of the expansion cap so that the expansion cap extends further from the concrete wall hole, so that the anchor bolt does not come out. In the background art, , There is no portion for holding the anchor bolt so that it does not fall off when the nut is fastened. Therefore, if the nut is fastened with the fastener body and the fixing member assembled to the anchor bolt in this state, As the anchor bolt is pulled out of the concrete wall, the fixture body and fixing member through the anchor bolt can not be firmly fixed in the concrete wall.

In addition, there is a problem that the tip of the leg portion of the fixture body that penetrates the heat insulator is sharp and the concrete wall is damaged or damaged when the nut is tightened. In this case, when the tip of the sharp leg portion penetrates the concrete wall, (Deviation deviating to one side) may be generated, and the width of the fixture main body protruding from the concrete wall to the marble (facer) side may be varied, which is a problem in precision construction.

Therefore, when tightening the nut to fix the fastener body through the anchor bolt, the anchor bolt is prevented from escaping out by the tightening force of the nut, so that the anchoring bolt can be firmly fixed, and at the same time, So as to improve the workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

The anchor assembly 20 is used to fix the exterior material 14 to the concrete wall 10 after the heat insulating material 12 is applied to the concrete wall 10 as shown in FIGS. 1 to 3 and FIG.

The anchor assembly 20 includes an anchor bolt 22, an extension cap 24, a sleeve 26 for preventing anchor bolt seizure, a ring 28 for removing a gap, a base bracket 30 for protecting the heat insulating material, 40 and a tightening nut 50.

2, the anchor bolt 22 includes a head portion 221 having a gradually enlarged section at its tip, a shaft portion 222 extending from the smallest end surface of the head portion 221, And a male screw 223 formed in a predetermined section. At this time, the maximum cross-sectional diameter of the head portion 221 is equal to the inside diameter of the perforated wall hole 11 of the concrete wall 10.

The anchor bolt 22 can be inserted into the wall hole 11 of the concrete wall body 10 with the head portion 221 facing forward. The overall length of the anchor bolt 22 is longer than the sum of the depth of the wall hole 11 and the thickness of the heat insulating material 12. [

The extension cap 24 is inserted into the shaft portion 222 of the anchor bolt 22 and is extended by the head portion 22 by the biasing force and is forcibly inserted into the wall hole 11. At this time, the extension cap 24 has one or more cut-out portions 24a, which are cut at a predetermined length in the longitudinal direction so as to facilitate opening. At this time, the striking force is usually generated by striking a sleeve (not shown) having a pipe section.

The sleeve 26 for preventing the anchor bolt from falling off is inserted after the ring 28 is inserted into the shaft portion 222 of the anchor bolt 22 with the pipe section. The anchor bolt non-dropping sleeve 26 has an appropriate length so that the anchor bolt 22 can not escape from the wall hole 11. [ That is, the length of the sleeve 26 for preventing the anchor bolt from coming off has a length such that it is in close contact with the inner surface of the angle plate 301 on which the elongated hole 301a of the base bracket 30 serving as the heat insulating material protecting member is formed as shown in Fig.

The hole clearing ring 28 is inserted into the shaft portion 222 of the anchor bolt 22 and is positioned between the expansion cap 24 and the sleeve 26 for preventing the anchor bolt from slipping off. The hole clearing ring 28 has a tapered cross section for facilitating insertion into the wall hole 11. [ The hole gap removing ring 28 removes a gap between the wall hole 11 and the anchor bolt 22 to prevent sagging of the anchor bolt 22 receiving the vertical load of the casing member 14.

In the meantime, although the ring 28 for removing the hole gap and the sleeve 26 for preventing the anchor bolt from coming off are separated from each other, they can be integrally formed.

On the other hand, the hole-gap removing ring 28 and the anchor bolt-preventing sleeve 26 may be formed of a metal or a synthetic resin having rigidity.

The base bracket 30 for protecting the heat insulating material is made of a steel material and protects the heat insulating material 12 (for example, styrofoam) when the tightening nut 50 is tightened and at the same time prevents the anchor bolt 22 from sagging. The base bracket 30 for protecting the thermal insulation material has an angle plate 301 having a long hole 301a formed at the center thereof, a plurality of tapered wedge plates 302 bent to one side from the angle plate 301, an angle plate 301 A plurality of reinforcing beads 303 formed on the tapered wedge plate 302 and a plurality of caulking parts 304 for securing bending rigidity inside the bent parts of the tapered wedge plate 302. At this time, the long-side direction of the long hole 301a is perpendicular to the load direction of the casing member 14.

The tapered wedge plate 302 has a generally trapezoidal shape. At this time, the tapered wedge plates 302 may be formed of one pair or two pairs, as shown in FIGS. 1 and 4A. In addition, the tapered wedge plate 302 may be divided into a single surface as shown in FIG. 4B. In addition, the tapered wedge plate 302 may have a round shape in order to secure the bending rigidity at the end portion as shown in FIG. 4C.

As shown in FIGS. 1 and 8, the angle bracket 40 for attaching an outer material is fixed and installed by a tightening nut 50 through an anchor bolt 22 and a base bracket 30, ). The exterior member mounting angle 40 has an L shape and has a long hole 401 penetrating through the right angle surface and is inserted into the anchor bolt 22 and placed in contact with the angle plate 301. [ The elongated hole 401 of the facing member mounting angle 40 is formed in a direction perpendicular to the elongated hole 301a of the base bracket 30 serving as a heat insulating material protection member.

The unexplained reference numeral 52 is a washer.

A construction method of the casing member 14 using the anchor assembly 20 thus configured will be described. The exterior material 14 may be, for example, marble.

5, a heat insulating material 12 is applied to a concrete wall 10 and then drilled in a concrete wall 10 to form a wall hole 11 having a predetermined depth.

Next, the anchor bolt 22 is inserted into the wall hole 11 and inserted. At this time, the expansion cap 24 is inserted into the anchor bolt 22 while being inserted. Therefore, the head portion 221 of the anchor bolt 22 is brought into contact with the inside of the wall hole 11.

Then, the expansion cap 24 inserted into the anchor bolt 22 is punched out by a pipe type sleeve (not shown). The end portion of the expansion cap 24 is opened by the head portion 221 and the expansion cap 24 is forcibly inserted into the wall body hole 11 so that the anchor bolt 22 is fixed to the wall hole 11 do.

Then, as shown in Fig. 6, the hole-clearing ring 28 is inserted into the shaft portion 222 of the anchor bolt 22 and inserted into the wall hole 11. Therefore, the anchor bolt 22 is supported by the wall hole 11 via the hole-clearing ring 28, so that sagging is prevented even if the mounting load of the casing member 14 is generated.

Then, as shown in Fig. 6, the anchor bolt-preventing sleeve 26 is inserted into the shaft portion 222 of the anchor bolt 22.

Then, as shown in Fig. 7, the base bracket 30 serving as a heat insulating material protection member is inserted into the heat insulating material 12. As shown in Fig. At this time, the end of the tapered wedge plate 302 is inserted into the anchor bolt 22 through the elongated hole 301a formed in the angle plate 301 so as to be in contact with the outer surface of the concrete wall body 10.

The rear end of the anchor bolt slip prevention sleeve 26 is brought into close contact with the inner side surface of the angle support plate 301 on which the elongated hole 301a of the base bracket 30 serving as the heat insulating material protection member is formed, The base bracket 30 for supporting the heat insulating material is supported and supported.

Next, as shown in FIG. 8, the casing 40 is brought into contact with the base bracket 30 serving as a heat insulating material protection member, and the tightening nut 50 is screwed into the anchor bolt 22. At this time, the anchor bolt 22 is pulled in the direction of the arrow P, and the expanding cap 24 is further expanded. At the same time, the rear end of the sleeve 26 for preventing the disengagement of the anchor bolts is firmly brought into close contact with the inner surface having the elongated hole 301a of the angle plate 301 and is pushed in the direction of arrow I. As a result, the expanding cap 24 is further subjected to the force of entering the inside of the wall hole 11, so that the anchor bolt 22 is secondarily fixed to the wall hole 11. At this time, the sleeve 26 for preventing the anchor bolt from coming off and the base bracket 30 for protecting the heat insulating material are in close contact with each other.

As a result of this, the sleeve 26 for preventing the anchor bolt from slipping out prevents the anchor bolt 22 from being pulled out from the wall hole 11. [ That is, when the tightening nut 50 is fastened, the anchor bolt 22 is about to extend out of the wall hole 11 in the direction of the arrow P so that the sleeve 26 for preventing the anchor bolt slipping out is extended through the hole- The force for pressing the cap 24 for pressing in the direction of the arrow I opposite thereto is generated to prevent the anchor bolt 22 from being removed.

Therefore, as the tightening force of the tightening nut 50 is strengthened, the sleeve 26 for preventing the anchor bolt from being pulled further pushes the extension cap 24 toward the front end via the hole clearing ring 28 relatively, There is no possibility that the wall 11 will come out of the wall hole 11.

9, the pin 60 is provided in the elongated hole 401 of the facing material mounting angle 40, and the casing member 14 is inserted into the pin so that the anchor bolt 40 is fixed to the anchor bolt 40. As a result, (22) supports the load of the casing (14). At this time, the anchor bolt 22 is not detached from the wall hole by the sleeve 26 for preventing the anchor bolt from coming off.

Further, the anchor bolt 22 has no gap with the wall hole 11 by the hole-gap removing ring 28, so that sagging does not occur. Also, the end of the tapered wedge plate 302 has a trapezoidal shape, so that it is not sharpened and the base wall bracket 30 for protecting the thermal insulation material does not break the concrete wall 10.

The end of the tapered wedge plate 302 has a substantially trapezoidal shape so that when the end portion of the tapered wedge plate 302 comes into close contact with the concrete wall 10 as shown in FIG. 8, 10 can be maintained at the same time, and at the same time, the projecting width can be kept constant, thereby assisting in the precise construction of the facings.

Since the sleeve 26 for preventing the anchor bolts from falling off is supported by the center through the angle plate 301 of the base bracket 30 serving as a heat insulating material protection member, the base bracket 30 for protecting the heat insulating material, And the center of the sleeve 26 is supported by the sleeve 26 for preventing the anchor bolt from slipping off, thereby further increasing the rigidity of the base bracket 30 for supporting the heat insulating material.

10 to 17 show another embodiment of the anchor assembly 20A. The same components as those of the anchor assembly 20A described above are denoted by the same reference numerals, and description thereof will be omitted.

An anchor assembly 20A according to another embodiment of the present invention shown in Fig. 10 includes an anchor bolt 22, an extension cap 24, a ring 70 for removing a gap, a sleeve 26 for preventing anchor bolt from falling off, A base bracket 30 serving as a heat insulating material protection member, an outer member mounting angle 40, and a tightening nut 50.

Here, the anchor bolt 22, the extension cap 24, the sleeve 26 for preventing the anchor bolt from falling off, the base bracket 30 for protecting the heat insulating material, the angle bracket 30 for mounting the casing member, and the tightening nut 50 are the same as those It is like explanation of example.

However, the length of the sleeve 26 for preventing the anchor bolt from dropping out is shorter than the length of the sleeve 26 for preventing the anchor bolt from being detached as shown in FIGS. This is because the ring portion 70c forming the hole clearance ring 70 is brought into close contact with the outer side of the concrete wall 10 and the fastening end portion 70d is protruded so that the sleeve 26 for preventing the anchor bolt coming- The length is shortened as it protrudes. That is, the length of the sleeve 26 for preventing the anchor bolt from coming off has a length such that it is in close contact with the inner side surface of the angle plate 301 on which the elongated hole 301a of the base bracket 30 serving as the heat insulating material protecting member is formed as shown in Fig.

The hole clearance ring 70 is screwed through the male screw 223 formed on the shaft portion 222 of the anchor bolt 22 and is positioned between the extension cap 24 and the sleeve 26 for preventing the anchor bolt from coming off .

The hole clearing ring 70 is screwed through a male screw 223 formed on the outer peripheral surface of the shaft portion 222 of the anchor bolt 22 so that the expansion cap 24 is tightly contacted by screw tightening force, Of the anchor bolt 22 is further extended from the head portion 221 so that the anchor bolt 22 is fixed to the wall hole 11 in a secondary manner and fixed and at the same time a gap between the wall hole 11 and the anchor bolt 22 is removed do.

For this, the hole-clearing ring 70 has a female screw portion 70a formed through the center and fastened to the male screw of the anchor bolt 22, and a female screw portion 70a formed in a tapered shape from the outer side front portion, A tapered portion 70b which is inserted into the tapered portion 70b to remove a gap between the wall hole 11 and the anchor bolt 22 and a ring portion 70c which is extended from the tapered portion 70b and is in close contact with the outer side of the concrete wall body 10 And a hexagonal fastening end portion 70d which is formed from the ring portion 70c at the outer rear face portion and fastened through a fastening tool (not shown) such as a socket wrench.

The tapered portion 70b removes the gap between the wall hole 11 and the anchor bolt 22 and at the same time the ring portion 70c is in close contact with the outer side of the concrete wall body 10 Thereby preventing sagging of the anchor bolt 22 which receives the vertical load of the casing member 14.

In this case, the hole-gap removing ring 70 and the anchor bolt slip-off preventing sleeve 26 may be made of metal or synthetic resin.
