The present invention relates to a sleeve for penetrating the wall, and more specifically, to form a guide portion on one side of the sleeve body, to form an angled sprinkler insert in the plurality of insertion holes to couple the sprinkler head to the end of the guide, By forming a circular locking jaw inwardly at the end of the insertion hole, the sprinkler head can be directly installed in the sleeve without a separate tool, and the construction can be performed in the correct position, and the side wall type sprinkler head can be installed to reduce the work force. It is related with the sleeve for penetrating a wall.

In general, in a high-rise building such as various industrial facilities or apartments, sleeves for installing various electrical wiring, plumbing of gas facilities, and plumbing of fire-fighting equipment on floors, walls, and retaining walls are installed in formwork before concrete is poured.

Such a sleeve is first installed in a formwork and then embedded in a wall by pouring concrete, whereby a device for securing the wall penetration sleeve separately to the formwork is used to keep it out of position.

That is, conventionally, as shown in [1] to [2], in the domestic registration utility model No. 20-0442186 "cylindrical sleeve body 10 is installed between the formwork 200 and embedded in the wall, and Fixing means 21 is formed on one side of the sleeve body 10 so as to be fixed to the formwork 200, respectively, and the position adjusting plate 40 having a plurality of fixing protrusions 41 thereon. The formed plate-shaped fixing bracket 20 and the fixing bracket 20 is inserted into the position adjusting plate 40 and fastened to the fixing protrusion 41 via the elastic clip 50 and the formwork 200. The sleeve for penetrating the wall, which includes a fixing piece 30 having a plurality of fixing holes 31 formed on the outside thereof so as to be fixed to the wall, is disclosed.

As described above, the wall penetration sleeve 1 is fixed between the formwork 200 to form a passage of the pipe (piping) before the concrete is poured, and is easily constructed by adjusting the position of the sleeve 1 installed on the wall. It improves workability at the same time and can stably fix the pipes through the wall.

However, the conventional wall penetration sleeve is used only as a means for fixing the pipe through the wall, a sleeve that is used to secure the sprinkler head installed on the wall for fire suppression has been developed. none.

Therefore, although the sprinkler head is conventionally fixed using a sleeve used as a means for fixing a pipe, this has a disadvantage that involves a lot of inconvenience in operation.

That is, the sprinkler head has a disadvantage in that it is inserted into the sleeve body in a state of being wrapped with insulation, and then finished between the sprinkler head and the sleeve with cement (mortar). This is to prevent the sprinkler head from moving when the spray nozzle is mounted on the sprinkler head and water is sprayed, but there is a significant difference between the inner diameter of the sleeve and the outer diameter of the sprinkler head. It is not easy to accurately center the center of the sprinkler, and even if centered, the sprinkler head must be prevented in order to fix it with cement (mortar). It is a hassle to do.

In addition, the conventional method has to wait for a long time until the curing of the cement (mortar) as well as the difficulty of removing the cement (mortar) again to repair the defect when the sprinkler head leak occurs.

In addition, when the sprinkler head is fixed by using the conventional method, the sprinkler head is in a state of being wrapped by a heat insulating material, so that it is difficult to fix firmly, and the head is frequently damaged during water injection.

Therefore, the present invention has been made to solve the above problems, the present invention is installed between the formwork is embedded between the sleeve body and the wall, and the outer circumferential surface to be coupled to the end of the sleeve body, respectively, fixed to the formwork In the sleeve for penetrating the wall made of a fixing member formed with a fixed stone piece of the guide portion, a guide portion having an inclined guide surface for guiding the sprinkler head is formed on one side of the sleeve body, one side of the guide portion by fitting the sprinkler head A sprinkler insert for coupling is formed, and at the end of the insertion hole, a sleeve for penetrating a wall for installing a side wall type sprinkler head composed of a locking jaw for preventing the sprinkler head from being exposed to the outside of the sleeve body is provided. have.

As described above, the present invention forms a guide part, a sprinkler insertion part, and a locking jaw at one end of the sleeve main body to naturally guide the sprinkler head to the sprinkler insertion part by the inclined guide surface of the guide part, thereby making the sprinkler head easily without any tools. It can be installed in the sleeve, and the center of the sprinkler head and the center of the sleeve can be exactly matched, and it is possible to work alone without the need for another operator to hold the sprinkler head.

In addition, the present invention is a structure in which the sprinkler head is firmly coupled to the sleeve so that it is not necessary to finish or cure with cement (mortar), thereby significantly reducing work time.

In addition, the present invention is a structure that the sprinkler head is firmly coupled to the sleeve to prevent damage to the sprinkler head, it is a very useful invention that is easy to remove the sprinkler head from the sleeve, easy to repair and repair.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
