[Conventional technology]

At construction sites, for example, various materials such as ceiling base materials, piping, ducts, lighting equipment, etc. When suspending and supporting parts and equipment from a concrete ceiling, conventional methods An anchor 1 and a hanging bolt 3 as shown at 5 are used. When using the hanging bolt 3, the anchor 1 with the internal thread 1A is pre-condensed. Bury it in the cleat ceiling C. The hanging bolt 3 is used for concrete such as ceiling base materials, piping, ducts, lighting equipment, etc. The lower end is connected to a member or fixture to be hung from the ceiling C, and a 3A male screw is attached to the upper end. is formed. Then, attach the male hanging bolt 3 connected to the ceiling base material, piping, duct, lighting equipment, etc. Screw the screw 3A into the female thread 1A of the anchor 1, and connect these ceiling base materials, piping, and ducts. Lighting equipment, etc. are suspended and supported from the concrete ceiling C.

0003

[Problem that the idea aims to solve]

However, in such a conventional hanging bolt 3, the male thread 3A is replaced by the female thread 1A. It is necessary to rotate the suspension bolt 3 in order to screw it into place, so it is difficult to rotate it at high places. The movement operation is troublesome, and when the number of hanging bolts 3 increases, it may cause damage to the concrete wall. There was a problem in which the efficiency of the connection work could not be increased. This invention was devised in view of the above circumstances, and the purpose of this invention is to When supporting materials, piping, ducts, lighting fixtures, etc. from concrete walls. Concrete is a concrete material that can be easily connected and improves the efficiency of this work. An object of the present invention is to provide a wall hanging device.

【Example】

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 is a cross-sectional side view of the concrete wall hanger, Figure 2 is a side view of the shaft member, and Figure 3 is A perspective view of the same is shown. The concrete wall hanger 11 according to the present invention is embedded in a concrete ceiling C. A cylindrical member 13 connected to the concrete ceiling C to be supported by the members, equipment, etc. The shaft member 15 is connected to the shaft member 15. The cylindrical member 13 is arranged so that the lower end 1301 is located on the concrete ceiling surface C. The inner peripheral surface of the body part 1302 and the upper end part 1303 form an open space below. A gap 1304 is formed.

[0006] In addition, the inner circumferential surface portion near the lower end portion 1301 is smaller than the inner circumferential surface of the body portion 1302. A collar portion 1305 is formed with a small diameter. The upper surface of the flange 1305 is formed of a flat surface 1305A, and the inner surface of the flange 1305 is The circumferential surface and the lower surface are tapered surfaces 1305B, 13 whose diameter increases toward the bottom. It is made of 05C.

[0007] The shaft member 15 has a shaft portion 1501 having a smaller diameter than the inner diameter of the collar portion 1305. The lower part of this shaft part 1501 is a member to be supported by the concrete ceiling C. Connected to fixtures, such as ceiling underlayments, piping, ducts, and lighting fixtures by appropriate means. It is something that An engaging body 1502 that can be elastically deformed in the radial direction of the shaft is provided on the upper part of the shaft portion 1501. It is formed.

[0008] The engaging body 1502 is inserted into two cross-shaped slits 1503 in the shaft portion 1501. Therefore, four engaging bodies 150 are formed at equal intervals in the circumferential direction around the center of the shaft. 2 is formed with a tapered conical surface 1502A, and this conical surface A spherical surface 1502B is formed at the tip of the surface 1502A. The lower end of this conical surface 1502A is formed with a larger diameter than the shaft portion 1501, The lower end of the surface 1502A and the shaft portion 1501 are formed by an annular flat surface 1502C, In this embodiment, this flat surface 1502C portion corresponds to the bulge. Note that the tapered surfaces 1305B and 1305C of the flange 1305 and the circle of the engaging body 1502 The conical surface 1502A and the spherical surface 1502B are used to insert the engaging body 1502 into the cylindrical member 13. This is to make this insertion easier when doing so. The size of the portion of the engaging body 1502 where the conical surface 1502A is formed is as follows: 1502 is elastically deformed inward in the radial direction of the shaft and passes through the flange 1305. When inserted into the space 1304 from the flange 1305, the elastic It is formed in a size that allows it to be accommodated in the space portion 1304 after returning to its original state.

[0009] Since this embodiment is configured as described above, for example, ceiling base materials, piping, ducts, etc. When supporting parts and equipment such as lighting fixtures by suspending them from a concrete ceiling C, the lower end The part 1301 is positioned on the lower surface of the concrete ceiling C to form a cylindrical shape on the concrete ceiling C. The member 13 is buried. Then, the lower part of the shaft member 15 is connected to the ceiling base material, piping, ducts, and lighting by appropriate means. The engagement body 1502 on the upper part of the shaft member 15 is connected to a member or device such as an instrument, and the engagement body 1502 is connected to the collar part 130. 5 into the cylindrical member 13. Alternatively, the engagement body 1502 on the upper part of the shaft member 15 is pushed into the cylindrical member 13 from the flange 1305, and then the lower part of the shaft member 15 is pushed in as appropriate. Connect to ceiling base materials, piping, ducts, lighting fixtures, and other members and equipment by means.

0010 By this pushing operation, the engaging body 1502 C and the conical surface 1502A, the shaft member 15 is elastically deformed inward in the radial direction, and the flat surface is When 1502C passes through the flange 1305, its elasticity causes Return to original state. Then, the flat surface 1502C of each engaging body 1502 is connected to the flat surface 130 of the collar portion 1305. 5A, the shaft member 15 is securely connected to the cylindrical member 13, and thereby the ceiling Base materials, piping, ducts, lighting fixtures, and other components and equipment are suspended from concrete ceiling C. will be supported.

[0011]

[Effect of the idea]

As is clear from the above explanation, according to the present invention, ceiling base materials, piping, ducts, lighting For easy operation of parts and equipment such as light fixtures by pushing the engaging body of the shaft member into the cylindrical member. Easy to connect to concrete ceiling as it can be connected to concrete ceiling easily The efficiency of these operations can be greatly improved even when there are many connection points. Becomes Noh.
