Description

{A CLIMBING WALL BEING MOUNTED EASILY}

The present invention relates to an artificial rock wall, and more particularly, to an artificial rock wall improved in installation workability so as to improve installation workability and reduce installation cost.

In general, artificial rock climbing is one of the four seasons leisure sports that climb rocks with bare hands with the help of auxiliary equipment by making rock wall in the inside of the building, outside wall or separate structure, punching holes in the wall, or attaching artificial handles.

Artificial rock climbing is more safe than natural rock climbing, and can be enjoyed regardless of the weather and season. It can be enjoyed by both sexes for a small fee, and it is effective for strengthening the muscles of arms and legs. There is an increasing trend of people enjoying climbing.

In response to this trend, large-scale artificial rock walls with a height of tens of meters are installed in national parks and the like. An artificial rock wall of this size is not simply attached to a climbing holder (a climb hold, hereinafter referred to as a holder), but a separate frame (fixed body) is formed in a specific shape, And a step of attaching and mounting a plurality of rock wall panels made of molded FRP material.

Of course, various types of holders are fixedly installed on the outer surface of the rock panel according to the degree of climbing difficulty.

However, the conventional artificial rock wall has a problem in that the installation structure is complicated, so that a large cost is required for the facility and reliability is poor in relation to safety.

In order to solve such a problem, Korean Patent Registration No. 10-0725379 filed by the applicant of the present invention and registered with the Korean Patent Registration No. 10-0725379 (published on June 28, 2007) discloses an installation structure system for climbing artificial rock wall The present invention provides a frame structure for an artificial rock wall and an installation structure system of a rock wall panel attached to the exterior thereof. In particular, it is possible to provide an artificial rock wall panel which can reduce installation cost and is structurally safe and easy to install And in order to solve such a problem, a bracket plate provided with a bolt hole integrally protrudes from the inner surface of the body of the rock wall panel; The rock panel and the frame are arranged in a zigzag shape along the longitudinal direction of the artificial rock wall and are connected to each other by a connecting bar connected to the frame plate at one end by a bolt hole provided at both ends thereof, Structure.

However, since the above-described structure requires the use of a separate bracket plate for installing the rock wall panel and the frame, there is a problem that the construction is complicated and the installation cost and time are long.

In order to solve such a problem, an artificial rock wall installation structure according to a patented registration number 10-1031649 (Published on Mar.

The technique according to the above-mentioned Japanese Patent No. 10-1031649 can reduce the installation cost of the artificial rock wall and make it possible to firmly install the artificial rock wall with a simple structure, and to easily install the artificial rock wall, So that the eccentric phenomenon can be prevented and the rigidity can be sufficiently maintained in the structure.

In the technique according to the above-mentioned Japanese Patent No. 10-1031649, a method of fastening a connecting member to a tubing rail was as follows.

A bolt hole is formed in the tubing rail at regular intervals in the longitudinal direction. Screw holes for fastening the bolt hole and the bolt are formed at the rear end of the connecting member. By screwing the bolt hole and the through hole with bolts, Respectively.

However, the technique described above and the above-mentioned Japanese Patent No. 10-1031649 have the following problems.

In the tubing rail, bolt holes were formed at equal intervals. Since the connecting member could be fastened only at a predetermined position with the bolt hole, the fastening operation of the connecting member was inconvenient.

In addition, since the connection member can be fastened only at a predetermined position, the size of the connection member has to be constant. Therefore, when the length of the connection member is large or small, the connection member can not be used for fastening.

The connecting rod 120 is screwed to the screw hole 161c of the position variable slider 161 through the connecting rod 120 in a state where the connecting hole 120a of the connecting rod 120 is aligned with the neck hole 142, 120) to the fastening portion (132), and the tightening bolt (162)
The connecting rod 120 of the connecting rod 120 is inserted into the threaded hole 161c of the position variable slider 161 and the neck hole 142 of the position varying slider 161, And the rear end of the connecting rod 120 is in close contact with the side surface 132a of the coupling part 132, the body part 162b of the tightening bolt 162 is fastened to the coupling part 120 of the coupling rod 120, When the fastening bolt 162 is screwed to the screw hole 161c of the position variable slider 161 through the fastening bolt 120a, the end of the body portion 162b of the fastening bolt 162 is inserted into the through hole 141 And the connecting rod 120 is pressed against the stepped surface 141a of the through hole 141 so that the connecting rod 120 is in contact with the back surface 141b of the fastening bolt 162 And is press-fitted between the head portion 162a and the side surface 132a of the fastening portion 132,
One end of which is fixed to one side of the rear face 161b of the position variable slider 161 and the other end is fixed to the rear face 141b of the through hole 141 of the rail 140 to exert an elastic force, ), ≪ / RTI >
The position variable slider 161 is fixed to the inside of the through hole 141 by the resilient supporting force of the elastic piece 170 so that the through hole 141 of the rail 140, And is fixed to the inside of the through hole (141) by an elastic supporting force of the elastic piece (170) when an external force is removed, the artificial rock wall having improved installation workability.
The method of claim 3,
The elastic piece 170 is composed of a leaf spring 170,
A seating groove 170a for seating the end of the tightening bolt 162 is formed on the elastic piece 170 at a position corresponding to the screw hole 161c formed in the position variable slider 161,
When the position variable slider 161 is moved by the elastic force of the elastic piece 170 so that the position variable slider 161 moves up and down along the through hole 141, The both ends of the front surface 161a of the position variable slider 161 are moved toward the rear surface 161b so as to be brought into close contact with the boundary edge where the step surface 141a of the through hole 141 and the neck hole 142 meet And an engaging guide groove (161e) is formed in the guide groove (161e).
