Description

[Detailed description of the invention] This invention aims to streamline the construction of reinforced concrete structures or steel-framed reinforced concrete structures by suspending support fittings for piping equipment, ceiling bases, etc. from concrete slabs or sloped roofs. Concerning flexible inserts for construction that improve reliability and practicality.

Conventionally, when suspending and supporting support fittings for piping equipment from a concrete slab in an oblique position, or when suspending ceiling base materials from the roof of the top floor of a concrete structure, it is necessary to In most cases, when a suspension bolt is screwed into an insert mounted at right angles, the suspension bolt is bent at the construction site each time.

For this reason, not only does construction work at the construction site take a lot of effort and effort, but when it comes to heavy piping, a significant amount of concentrated load is applied to the bent portions of the suspension bolts, which is a serious drawback that can cause breakage accidents. It was hot.

This idea was created in view of the conventional problems mentioned above, and its purpose is to ensure that hanging bolts can always be hung safely and reliably within a predetermined range from a general concrete slab or a sloped roof on the top floor. It is an object of the present invention to provide a flexible insert for construction that can be easily constructed, rationally, and practically effective.

In order to achieve the above object, this invention provides a flange at the upper end of the body, and connects a large diameter hollow part with a receiving surface having a through hole whose inside diameter gradually becomes smaller from the lower end along the axis. The installed concrete anchor member and
The concrete anchor member is accommodated so as to be able to slide up and down and swing from side to side along the through hole and cavity, and has a head formed at the upper end of the body to fit the receiving surface of the concrete anchor member. , consisting of a mounting member with a female screw hole provided along the axis from the lower end, and a support member into which the body of the concrete anchor member is fitted and which supports several nails on the side so as to protrude downward from the bottom. It is characterized by

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a partially longitudinal sectional front view of a flexible construction insert according to a first embodiment of the invention.

Reference numeral 1 designates a concrete anchor member made of metal, with a planar circular flange 3 protruding from the upper end of the body 2, and an oval-shaped through hole that gradually becomes smaller in diameter from the lower end along the center and widens left and right. 4, and a circumferential hemispherical seat surface 5 above the through hole 4, and a large-diameter planar elliptical cavity 6 that expands left and right along the coaxial center. The lower peripheral side of the cavity 6 is formed into a hemispherical shape.

7 is a lid piece that closes the upper end of the cavity 6.

8 is the through hole 4 of the concrete anchor member 1
and a mounting member that is housed so as to be slidable up and down and swingable from side to side along the inside of the cavity 6, and has a spherical head formed at the upper end to fit the upper surface of the receiving surface 5 of the concrete member 1. A female screw hole 10 is integrally formed at the lower end of the portion 9 along the axis.

Note that the shape of the head 9 is not limited to the above shape, but may be any other shape as long as it is swingable.

Reference numeral 12 denotes a support member made of synthetic resin, which has through holes 14, 14 formed at two opposing locations on the side surface of the cylindrical body 13 into which the body of the concrete anchor member 1 is fitted, penetrating downward from the upper part of the side surface. At the same time, a seat surface 15 is formed on the bottom surface of this cylindrical body 13.

Reference numeral 16 denotes two nails, which are attached to the seat surface 1 of the support member 12.
5 Fitted into the nail hole of the support member so as to protrude downward by an appropriate length.

An example of how the flexible insert of the first embodiment configured as described above is used will be described below.

As shown in FIG. 2, the head of the concrete anchor member 1 is directly hammered and nailed at a predetermined position on the formwork P, and then concrete is poured.

After curing, the formwork is dismantled, and the hanging bolt B is screwed into the female screw hole 10 of the mounting member 8 protruding from the bottom, and the hanging bolt B is screwed into the vertically downward or diagonal state within the swing range of the mounting member 8. It can be hung from the ceiling and used for piping equipment and for attaching ceiling base material.

As described above, according to the flexible insert for construction of this invention, the performance of the insert is sufficiently maintained, and the direction of the hanging bolt B, which is screwed into the insert and suspended, can be freely and arbitrarily changed within a predetermined range. It has an excellent function for installing piping equipment with a new earthquake-resistant design or for installing a ceiling underlayment under a sloped roof, and the mounting member 8 is housed and held within the concrete anchor member 1 when installing the formwork. As the formwork is dismantled, it naturally descends and protrudes, so the insert position can be confirmed and the hanging bolts can be screwed in efficiently, resulting in excellent workability.
It is a flexible insert for practical construction.

Next, another example of this invention will be explained.
FIG. 3 is an enlarged longitudinal sectional front view of the mounting member of the second embodiment. The mounting member 81 has the same shape as the first embodiment, and is provided with a female threaded hole 101 extending along the axis from the lower end to the upper end.

In this case as well, the same actions and effects as in the first embodiment can be expected, and since the female threaded hole 101 is penetrating as described above, when positioning piping etc., some error in the dimensions of the hanging bolt B can be avoided. Since it has a sufficient amount of movement even if it occurs, it has the effect of being able to be reliably suspended in a predetermined position.

In addition, by attaching an elastic body such as a spring above the head of the mounting member to keep the mounting member pressed at all times, it can be expected that the mounting work of the mounting bolt can be easily performed.

As explained in detail above, according to the insert of this invention, the direction of the hanging bolt can be freely adjusted.
In addition, it can be changed as desired, has excellent workability and construction efficiency, and has excellent practical effects, such as being able to confirm the insert position at a glance.
