Description

[0001] The present invention relates to a through-hole sleeve for wall retaining wall improved in installability,

The present invention relates to an improved wall-mounted type wall structure in which a hole can be provided by being fixed in a formwork before a concrete is poured to perforate a hole having a predetermined diameter in a wall for electric wiring, drainage, ventilation, The present invention relates to a through sleeve for a retaining wall, more specifically, a first and a second sleeve coupled to a first and a second support plates fixed to a formwork, And a wall-retaining wall for a retaining wall.

In order to achieve this, a through-hole sleeve having a predetermined diameter and width is fixed to the inside of the formwork, and then concrete is poured into the through-hole to form a through-hole.

The through sleeve has a fastener at both ends of the through sleeve, fixes an "a" shaped engaging piece to the upper end of the fastener, fixes the bent end of the engaging piece to the upper side of the mold, .

However, since the conventional through sleeves are fixed to the building mold through a coupling piece having a predetermined length, the height of the building is not freely adjustable. In order to install the through sleeve on the building mold, the upper end of the coupling piece is fixed to the building mold, The process of fixing the lower end of the engaging piece to the through sleeve is cumbersome and thus the workability is deteriorated.

In order to solve the above problem, a spiral through sleeve of Korean Patent Laid-Open Publication No. 10-2009-0054790 (2009.06.01.) Has been proposed. The spiral sleeve is formed in a tubular shape. On one inner circumferential surface, And a first blocking member formed on the other side of the first blocking member and having a first fixing pin protruding from a central portion of the first blocking member to penetrate through a building foam, And a second tubular body formed with a second blocking film formed on the other side thereof and a second fixing pin protruding from the center of the second blocking film and penetratingly connected to the building foam, have.

However, in the above-mentioned through sleeve, a through sleeve is proposed in which the through sleeve is rotated by being coupled with an equally divided female or male screw so as to be adjusted in length. However, The length of the screw is adjusted by the pitch of the thread only per one rotation of the screw, so that it is necessary to rotate the screw a lot, so that it takes a lot of time to adjust the length of the through sleeve. Further, in adjusting the length of the conventional penetrating sleeve, the length of the width can not be known. Thus, there is a problem that it is very inconvenient and time-consuming because the length of the width of the sleeve is not known. In addition, the size of the first and second support caps are different from each other, so that the manufacturing cost of each injection mold is increased, inconvenience arises in separately storing and using the caps, and the length of the retaining wall is long There is a problem in that a separate pipe must be cut and adjusted because there is no penetrating sleeve.

Also, as a technique for improving the above-mentioned conventional problems, there has been proposed a through sleeve for a retaining wall having a multi-threaded thread of Korean Patent Registration No. B1-110969634 (Feb. 23, 2013) The first support cap is provided at one side thereof with a coupling structure in which the first support cap is inserted and removed. At the other end, an inner circumferential surface of the other end is formed with a predetermined length of multi- A first sleeve having a pin protruding from the first sleeve and having a circular tube shape and being coupled to the other side of the first sleeve and having a second supporting cap inserted and removed at one side thereof, And a second fixing pin protruding from a central portion of the second support cap, the second fixing pin being coupled to the die; The first sleeve and the second sleeve are interchangeable in order to prevent slipping when the first sleeve and the second sleeve are screwed together. In order to prevent sliding of the first sleeve and the second sleeve, And the second sleeve is integrally formed on the outer circumferential surface of one end of the second sleeve, and the first sleeve and the second sleeve are fastened and loosened in the mutually rotating direction, so that the multi- Wherein a width graduation plate is formed on the outer side of the second sleeve so as to show the lengths of both ends of the first and second sleeves controlled by the multi-thread female threads and the multi-thread threads, The grip portion and the second grip portion may be formed by a plurality of semicircular grip portion projections on the circular outer surface or may be polygonal, and the first support cap and the second support cap may be formed on the surface And it characterized in that formed as the planar surface.

The first sleeve and the second sleeve are coupled by a multi-row screw to increase the stroke distance, so that the movement of both members can be easily controlled even with a small rotation, and the movement distance can be visually checked It is possible to provide an effect that can be confirmed.

However, there is a disadvantage in that the above-described construction also has to be repeated several times in order to assemble the first sleeve and the second sleeve, and the supply is generated between the plane graduation plate and the multi-filament thread in the planar shape, and the mortar flows into the through- And there was a need to clean the inside of the penetrating sleeve after the construction.

Therefore, the inventor of the present invention researched all the problems of the conventional through sleeve.

That is, in the present invention, the protruding portion formed with the male thread of a narrow width is formed in the first sleeve in the axial direction, and the protruding portion formed with the male thread in the second sleeve is formed with the guide groove, And the shielding plate formed on the blocking ring is positioned in the guide groove so that the protruding portion can be moved in a state in which the protruding portion is rotated It is possible to block the introduction of the mortar into the penetrating sleeve by blocking the guide groove, thereby making it possible to quickly install the penetrating sleeve while preventing the inflow of the mortar into the penetrating sleeve and cleaning the inside of the penetrating sleeve The present invention provides a through sleeve for a retaining wall having improved installation properties so as to eliminate troublesome work. The present invention has been completed based on the technical problem.

The first sleeve and the second sleeve have a first male thread and a second female thread. The first and second sleeves are fitted to the outside of the first and second sleeves. The first and second support plates, And a through-hole for the wall retaining wall. A protrusion formed in the first sleeve in an axial direction; And a guide groove in which the protrusion is inserted is axially formed in the female screw formed on the second sleeve so that the protrusion formed on the first sleeve can be slid in the axial direction in the guide groove.

The second sleeve is formed with a blocking ring that freely rotates in contact with the first sleeve. A blocking plate is formed in the blocking ring to form a protrusion inner groove conforming to the guide groove, thereby blocking the guide groove .

Third, the engagement of the second sleeve and the blocking ring forms a latching frame at the end of the second sleeve, and the blocking ring has a plurality of latching pieces formed with locking protrusions engaged with the latching frame.

In the case of using the through-wall sleeve for wall retaining wall provided with the improved installation property provided by the present invention, the following effects can be obtained.

The assembling of the first sleeve and the second sleeve is facilitated since the protrusions formed in the first sleeve and the blocking ring and the protrusion internal grooves are slid in the axial direction while being positioned in the guide grooves formed in the second sleeve.

- In use, the protrusions formed in the first sleeve and blocking ring and the protrusions inward grooves are slid in the axial direction and moved to the use position, and then the first sleeve is rotated in the circumferential direction, thereby improving workability.

The guide groove formed in the second sleeve is sealed by the blocking plate formed in the blocking ring, so that the molten metal can be completely blocked from flowing into the through sleeve.
