Description

[Detailed Description of the Invention] The present invention relates to an improvement of an embedded device which is embedded in the concrete wall of a concrete building and into which a hanging bolt is screwed.

Conventionally, in order to embed such an embedded device in a concrete wall, nails that protrude downward from both sides of the embedded device are driven into specified locations on the concrete formwork, and the embedded device is attached to the formwork. Later, concrete was poured,
This is done by dismantling and removing the formwork, but since the nails that are hammered into the concrete formwork are integrally protruded from the embedded tools, the iron nails do not touch the concrete wall after the formwork is dismantled. Therefore, it was necessary to bend or cut off the protruding nail.

In order to eliminate such problems, the present invention is constructed so that a mounting plate with nails inserted on both sides is removably fitted to the bottom surface of the main body of the embedding device, which has a screw tube. For use in concrete buildings, characterized in that the fixture body is embedded in the poured concrete wall, and the mounting plate is separated from the embedded fixture body integrally with the formwork when the formwork is dismantled. It provides an implant.

An embodiment of the present invention will be explained with reference to the drawings. 1 is mainly a synthetic resin embedded device, and a vertical hole 2 is provided between the center of the upper end surface and the center of the lower end surface, and a metal screw is inserted into the vertical hole 2. 3 is inserted and fixed integrally, and a circular head 3a integrally connected to the upper end of this screw tube 3 is brought into contact with the upper end surface of the main body 1 of the implant.

The shape of the implant main body 1 is a cylindrical part 1a provided with a vertical hole 2.
A rib portion 1b is integrally provided on both sides of the rib portion 1b, and the lower end thereof is formed into an oval or track-shaped seat plate portion 1C, and the head portion 3a of the aforementioned spiral tube 3 is made larger in diameter than the cylindrical portion 1a. The outer periphery of the lower surface thereof protrudes outward from the cylindrical portion 1a, and a peripheral wall of an appropriate height extends downward to the lower surface of the implant main body 1, that is, the outer periphery of the lower surface of the track-shaped seat plate portion 1C. 4 is installed protrudingly.

Reference numeral 5.5 denotes a small-diameter fitting hole bored on both sides of the lower surface of the seat plate portion 1C of the implant main body 1 toward the rib portions 1b, lb.

Reference numeral 6 denotes a central hole bored in the center of the lower surface of the implant main body 1 toward the cylindrical portion 1a, and has a slightly larger diameter than the screw tube 3. The lower end of the screw tube 3 is inserted into the central hole 6. An annular fitting groove 6a is formed between the screw tube 3 and the inner peripheral surface of the central hole 6 by locating the opening.
It is formed.

7 has its outer peripheral shape as the lower peripheral wall 4 of the implant main body 1.
is a mounting plate that has approximately the same shape as the inner circumferential wall surface of the wall 4 and is removably fitted to the circumferential wall 4, and has the fitting groove 6 in the center of its upper surface.
A protruding short cylindrical portion 8 that can be inserted into a is provided, and the central hole of the short cylindrical portion 8 is passed through between the upper and lower surfaces of the mounting plate 7. Protruding small diameter short cylindrical parts 9, 9 that fit into the small diameter fitting hole 5.5 provided in the part,
Nails 10 and 10 are inserted through the center holes of the small diameter short cylindrical parts 9, 9 and fixed, so that the lower surface of the head of the iron nail 10 is in contact with and locked to the upper end surface of the small diameter short cylindrical parts 9. The shaft part of the shaft protrudes downward.

Further, the thickness of this mounting plate 7 is formed to be approximately the same as the height of the peripheral wall 4.

To explain how to use the embedded device configured as above, first, the mounting plate 7 is fitted into the peripheral wall 4 provided on the lower surface of the embedded device main body 1, and the upper surface of the mounting plate 7 is attached to the bottom surface of the embedded device main body 1. A nail inserted into the short cylindrical portions 9, 9 by fitting the short cylindrical portion 8 into the fitting groove 6a and fitting the small diameter short cylindrical portions 9, 9 into the small diameter fitting holes 5, 5, respectively, while bringing the short cylindrical portion 8 into close contact with the lower surface. The mounting plate 7 is attached to the implant main body 1 with the top surface of the head 10 in contact with the inner bottom surface of the small diameter fitting hole 5.

Next, nails 10.10 protruding from the mounting plate 7 of the embedding device main body 1 are positioned at predetermined locations of the framed concrete formwork a, and the screw head 3a exposed on the upper end surface of the embedding device main body 1 is placed. The nails 10 and 10 are driven into the formwork a by hammering, and the lower surface of the mounting plate 7 is brought into close contact with the formwork 8 surface.

At this time, the screw cylinder head 3a is hit by a hammer or the like from the cylindrical part 1a and both side ribs lb, lb of the implant main body 1 to the upper surface of the mounting plate 7 and the small diameter short cylinder part which are in close contact with the lower surface of the seat plate part 1C. The information is transmitted to the nail head in contact with the inner bottom surface of nail 10.1.
0 can be entered smoothly and reliably.

After attaching an appropriate number of embedding tools to predetermined locations of formwork a in this manner, concrete is poured to construct a concrete wall.

When the formwork a is dismantled after curing the concrete, the mounting plate 7 sealed to the formwork a separates from the lower peripheral wall 4 of the embedding main body 1 and is removed together with the formwork a, and the concrete wall is removed. The main body 1 of the embedding device is buried so that the lower end opening of the screw tube 3 is exposed on the concrete wall surface, and a threaded rod or hanging bolt or the like is screwed into the screw tube 3.

In the above embodiment, the short cylindrical portion 8 was provided protruding from the center of the upper surface of the mounting plate 7, but the present invention can be used without providing such a short cylindrical portion 8.

In this way, the present invention has the screw tube 3 integrally fitted into the vertical hole 2 provided in the center of the implant main body 1, the lower end of the screw tube 3 being opened on the lower surface of the implant main body 1, and this embedded device A peripheral wall 4 protruding downward from the outer peripheral edge of the lower surface of the main body 1
This relates to an embedded tool for a concrete building, in which a mounting plate 7, in which the upper ends of the shaft rods of nails 10 and 10 are inserted into the peripheral wall 4, is removably fitted to the peripheral wall 4. Since the nails 10 are inserted into both sides of the mounting plate 7, unlike the conventional method in which the nails are protruded from embedded tools, it is easy to install the nails 10, and the nails 10 are not attached to the formwork a. When the upper end surface of the embedding tool main body 1 is tapped when driving the nail 10, the hammering force acts directly on the mounting plate 7 that is in close contact with the lower surface of the embedding tool main body 1 and the upper end surface of the nail head, and the nail 10 is driven smoothly and reliably. At C, the mounting plate 7 is fitted into the lower circumferential wall 4 of the embedding main body 1, and when pouring concrete, the concrete can be poured into the mounting plate 7 on the outer circumferential surface of the circumferential wall 4. It is possible to reliably prevent infiltration into the screw tube 3 of the implant main body 1 from the fitting part of When the concrete formwork a is dismantled, the mounting plate 7 comes off integrally with the formwork a and separates from the peripheral wall 4 of the embedding main body 1, so that the nails protrude from the concrete wall surface as in the conventional case. Since there is no need for bending or cutting iron nails, the embedding device main body 1 can be buried in a beautiful manner.
