Description

Cover over anchor an interpolation

The present invention relates to an anchor insert used in the groundwork of civil engineering or construction. The anchoring method is to connect high-strength (tensile force) to the steel by connecting it with a high-strength steel between the part of the civil engineering or construction contacting the structural ground and a stable settlement of a certain depth of the ground. Design Construction Instructions-) ". In general, the anchor insert used in the anchoring method is inserted into the groove of the lower body and the spacer formed in the lower body, and the injection hose for injecting grout at high pressure and the injected grout are cured. It is composed of PC steel wire which is tensioned to the ground.

In the anchor method, the insert is inserted into a hole drilled into the ground of civil engineering or construction, and acts as a skeleton of the grout that is injected and cured into the hole. The insert is located at the center of the grout injected into the hole. The grout must be cured to maximize the tension (tension) effect required by the anchoring method. In other words, the anchor insert must be cured at the center of the grout injected into the perforated hole, so that when the PC steel wire is tensioned (tensioned), it will exhibit sufficient tension (tension) effect with the part contacting the structure ground of civil engineering or construction. However, as shown in FIG. 2, the conventional anchor insert 20 is cured like the grout 10 in a state inclined to the inclined surface of the perforated hole, thereby sufficiently tensioning (tensioning) with the ground of a structure of civil engineering or construction. There was a problem of halving the effect of the anchor method.

The present invention was devised to solve the above problems, the injection hose is inserted into the spacer of the conventional anchor insert to pass through the center of the fixing head, and the cover is covered with the anchor insert for the perforated hole When the grout is injected into the cover, as the grout is filled in the cover, the cover enclosing the anchor insert swells up to the inner wall of the perforated hole, so the anchor insert is always located at the center of the diameter of the perforated hole (center of the injected grout). It is an object of the present invention to provide an anchor insert that exhibits an optimal effect of tension (tension) between grounds of civil engineering and construction by curing the grout.

When described in detail with reference to the drawings as follows.

1 is a perspective view showing the anchor insert 100 covered with the subject innovation cover, the inner body 80 is formed with a plurality of holes 90; A fixing head through which the injection hose 60 for injecting the grout 10 into the load-bearing body 80, the cured grout 10, and the PC steel wire 40 for tensioning (tensioning) the ground of a civil engineering or building structure 70 and; The protective cap 120 is formed with a bending binding projection 130 is coupled to the lower body 80, the cover 110 is configured to cover the insert configured as described above.

The hole 90 formed in the load bearing body 80 serves as an outlet through which the grout 10 injected through the injection hose 60 is discharged.

The injection hose 60 passes through the center of the fixing head 70, a predetermined length is inserted into the lower body 80, and the hole 90 through which the PC steel wire 40 passes symmetrically with the hose. At this time, the PC steel wire passing through the hole 90 serves to fix the one side of the cover 110 surrounding the waterproof insert and the anchor insert 20 by inserting the cockle cone 50.

Although the fixing head 70 shown in FIG. 1 is directly coupled to the lower body 80, the fixing head 70 may be separated from the lower body 80 and positioned at a predetermined distance. This is possible by supporting the anchor insert 20 with the PC steel wire 40 and the injection hose 60.

The protrusion 130 formed on the protective cap 120 serves to bind by bending the opposite side of the cover 110, one side of which is fixed to the fixing head 70.

Looking at the operating state in the hole (30) perforated anchor cover for the subject innovation cover configured as described above are as follows.

FIG. 3 is a state diagram when the grout 10 is injected into the drilled hole 30 by using the anchor insert having the cover of the present invention, and FIG. 2 when the grout 10 is not injected into the insert. As shown, it is inclined to one side of the obliquely drilled hole. At this time, when the grout 10 is injected into the injection hose 60 in the insert, the grout 10 is discharged through the hole 90 of the lower body 80, and the grout 10 is filled into the cover 110, thereby covering the cover ( 110 is swollen and the inner wall of the drilled hole 30 and both sides of the cover 110 are in contact, so that the hole 30 drilled at a large angle with the ground of the hole 90 in which the anchor insert 20 is drilled. Even when inserted into the anchor insert 20 is always cured with the grout 10 in the state (located in the center of the grout 10) in the center of the drilled hole (30).

The present invention is to be cured with the grout 10 in the state of being located in the center of the hole 90 (center of the injected grout 10) irrespective of the angle of the hole 30 drilled by the anchor method required by the anchor method Groundbreaking design that shows the optimal effect in anchoring method that connects the structure ground of civil engineering or construction to the stable settlement ground of any depth of ground and introduces high tension (tension) to the steel It is
