[0001] Apparatus for Separating Cocreate Slab by Making Wall [0002]

The present invention relates to a concrete pouring mobile partition foam, and more particularly, to a concrete pouring mobile partition foam for pouring or splitting concrete when only a part of a slab is to be poured when pouring concrete.

The slab of the concrete building is completed by placing reinforcing steel inside the formwork, placing concrete with a certain thickness on it and curing it. Reinforcing bars are often composed of two or more rows, and therefore consist of a lower steel bar and an upper steel bar. However, depending on the design, reinforcing bars can be laid out in more complex structures. Slabs of the same layer should normally be integrally connected. However, when the slab is oversized, the area is too wide, and if it exceeds the workload per day, it is necessary to partially install it and to put the rest on the next day. In this case, part of the mold of the slab is cut off vertically, and the concrete is poured in only a proper amount of work. In this case, Form.

Conventionally, a method of cutting a plywood or an iron plate to a predetermined size by a method for breaking or breaking the concrete has been used, but the installation work of the structure is very cumbersome and takes a lot of time, There is a problem in that the strength is lowered due to the lack of smooth connection with the section to be laid.

To correct this problem, Korean Patent Application Nos. 10-2009-0028579, 10-2006-0133516 or 10-2015-0105566 have been proposed.

However, there is a problem in that the structure of the device itself is complicated, and thus, the installation cost and the air flow rate are increased.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. First, an embodiment of the present invention will be described with reference to Figs. 1 to 2. Fig.

The concrete pouring partitioning foam according to the present invention is installed in a mold assembled to install a slab at the time of construction of a building, and one slab is partitioned to partially pour concrete, and the remaining part is poured into the next day to form an integral body .

The concrete pouring partition foam according to the present invention includes a fixed frame 10, a plurality of fixed pins 20 fitted in the fixed frame 10 and a cushion body 30 fitted in the fixed pins 20.

The fixed frame 10 is provided by bending a plate member as an elongate member to the left and right. The fixed frame 10 is formed of a side plate 11, an upper plate 12 and a lower plate 13 by being bent in a diagonal shape.

An upper fitting hole 14 and a lower fitting hole 15 are disposed at regular intervals along the longitudinal direction of the upper plate 12 and the lower plate 13 of the fixed frame 10.

The fixing pins 20 are vertically fitted to the upper fitting hole 14 and the lower fitting hole 15, respectively, so that they are installed in a row. The fixing pin 20 is composed of a head 22 and a stem 21 like a bolt or a nail. The stem 21 has a diameter that fits in the upper fitting hole 14, but the diameter of the head 22 is such that it can not pass therethrough. The length of the stem 21 of the fixing pin 20 is two to three times longer than the height of the fixed frame 10. [ Therefore, the lower portion of the stem 21 extends downward from the lower plate 13 of the fixed frame (see FIG. 2).

The cylindrical cushion body 30 having the fixing pin fitting hole 31 is fitted to the outside of the stem 21 of each fixing pin which protrudes downward from the lower plate 13 of the fixed frame. The cushion body 30 may be in the form of a heat insulating material to surround the refrigerant pipe or the hot water pipe. The cushion body 30 is completed by cutting the heat insulating material for pipes by a required length. The cushion body 30, which is formed by foam molding, can be compressed so as to have a reduced volume by an external force and has a property of returning to its original state when an external force is removed.

According to the embodiment of the present invention, the fixing pin 20 is made of a synthetic resin material and is integrally formed by injection molding. The stem 21 of the fixing pin may be provided as a hollow pipe or as a hollow rod.

When the cushion body 30 is engaged with each of the fixing pins 20, the adjacent cushion bodies 30 come into contact with each other as shown in FIG. 2, thereby preventing the poured concrete from flowing out to the outside.

The thickness of the wall of the cushion body 30 should be such that the reinforcing bars 1 and 2 can be penetrated. That is, the reinforcing bars 1 and 2 must be able to escape from the adjacent cushion bodies 30.

" 의 형태가 될 수도 있다. 즉 약간 움품 패인 정도가 되어도 무방하다. 이는 철근(1,2)을 끼워넣을 때 형태 변형에 대한 부담을 줄임으로써 쿠션체(30)의 내구성을 높이고 작업을 용이하게 하며 철근(1,2)이 끼워진 곳에 빈틈이 생기는 것을 억제할 수 있다. In the case where the cushion body 30 is rigid or the reinforcing bars 1 and 2 are thick, there is a gap between the reinforcing bars 1 and 2 and the cushion body 30 even after the reinforcing bars 1 and 2 are passed . Concrete may be lost through this gap. According to the embodiment of the present invention, a semi-cylindrical reinforcing seating groove 32 is formed on the side surface of the cushion body 30 in a direction perpendicular to the cushion body 30 as shown in Figs. 3 to 4 Two or more of them may be formed. The reinforcing seat groove 32 is not exactly a semi-cylindrical,

"This means that it is possible to have a slight dent in the form of a little dent. This reduces the burden on the shape deformation when the reinforcing bars (1, 2) are inserted, thereby enhancing the durability of the cushion body (30) And it is possible to suppress the occurrence of a gap at the place where the reinforcing bars (1, 2) are fitted.

Since the reinforcing bars are generally composed of the upper reinforcing bars 1 and the lower reinforcing bars 2, the seating grooves 32 may be provided on the upper and lower portions of the cushion body, respectively. When the thickness of the slab is determined, the position of the reinforcing bar is almost determined, so it is not difficult to determine the installation position of the seating groove 32. In addition, even if the height of the seating groove 32 is slightly different, there is no problem in working. The seating grooves 32 'and 32' 'may be provided at several different heights 32' and 32 '' along the circumferential direction of the cushion body. The operator may adjust the cushion body 30 while rotating the cushion body 30 so that the side where the seating groove 32 is not present between the adjacent cushion bodies does not contact the reinforcing bars.

According to another embodiment of the present invention, the upper plate 12 and the lower plate 13 of the fixed frame 10 are respectively fixed to the lower plate 13 with fixing pin drawing grooves 16 and 17 may be provided. This is to allow the fixing pin 20 to be inserted into or separated from the stationary frame 10 in the vertical direction as well as in the horizontal direction.

According to another embodiment of the present invention, as shown in FIG. 6, the head 22 of the fixing pin is made of a metal material, and may be fixed to the upper end of the stem 21 by insert molding. This is to improve the durability of the fixing pin by preventing breakage of the head when hitting the fixing pin with a hammer. The insertion pin 24 of the head is inserted into the stem 21. Instead of the coil spring to be described later, the elastic ring 23 can be fitted to the stem 21 and brought into contact with the bottom surface of the head. The elastic ring 23 made of rubber or urethane can be used instead of the coil spring to allow elastic flow of the fixing pin at a low cost.

According to another embodiment of the present invention, a coil spring (not shown) having a diameter that can be fitted into the cushion body 30 is provided on an extension of the stem 21 at a lower end of the fixing pin 20 , The coil spring can be supported on the bottom surface of the slab. This is to prevent the fixing pin from being damaged by elastically acting when the head 22 of the fixing pin is hit from above and separated from the cured concrete.

Hereinafter, another embodiment of the present invention will be described with reference to FIG.

The upper fitting hole 14 provided in the upper plate 12 of the fixed frame 10 is in the form of a circular hole through which the screw 25 can pass and the lower fitting hole 15 is open at the front, C "shape. A screw hole (21a) for fastening a screw (25) is provided at the upper end of the fixing pin (20). The side walls 15a and 15b of the lower fitting hole are formed by bending upward so that the portion of the side wall 15a and 15b contacting the cushion body 30 is not in contact with the sharp portion. As a result, the cushion body 30 can be prevented from being torn and the durability can be improved. In addition, since the side walls 15a and 15b press the cushion body 30 in surface contact, it is possible to prevent the cushion body 30 from flowing to some extent.

The side wall 15a in the fixing pin inlet / outlet groove 16 of the lower fitting hole 15 is gently opened so that the cushion body 30 can be easily fitted or removed through it. According to the present embodiment, the steps are put on the cushion body 30, then are inserted into the fixed frame 10 in the transverse direction, and fastened with the screws 25, which is completed. That is, it is very convenient to install. The screw 25 is composed of a round head 25a having a cross groove and a screw portion 25b. Since the strength of the fixed frame 10 is further improved by the side walls 15a and 15b, the fixed frame 10 may be selected to be thinner. Therefore, the weight of the fixed frame 10 is reduced, thereby reducing the work intensity of the operator. Ribs may also be formed on the side plate 11 (see Fig. 1) of the fixed frame 10 to further improve the strength of the fixed frame 10. Fig.

Hereinafter, another embodiment of the present invention will be described with reference to FIG.

FIG. 8 is an extension of the embodiment of FIG. 7, showing an embodiment in which ribs 21b are protruded at one or more positions along the longitudinal direction of the fixing pin 20. FIG. That is, the fixing pin 20 is composed of the elongated stem 21 and the rib 21 having the screw hole 21a. The present embodiment is intended to prevent the fixing pin 20 from being turned around in a state where it is fitted to the cushion body 30 and to more completely block the leakage of concrete, that is, to improve the watertight function.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
