This invention relates to an installation device for a floor inspection opening, and in particular to an installation device for a floor inspection opening that is designed to improve installation efficiency.

[Conventional technology]

Conventionally, when installing a floor inspection port on the floor, as shown in FIG. The other end of the attached connector 5 was welded and fixed to the reinforcement 2, and the area around the floor inspection opening 3 and the floor surface was filled with mortar 6.

[Problem that the invention seeks to solve]

However, in such a conventional example, not only is it time-consuming to pull out the reinforcement 2, but also welding work is required, so the welding work itself requires skill, and when installing the floor inspection opening, a welding machine, etc. equipment must be transported to the installation site,
The drawback is that the installation work is not easy.

Furthermore, welding work that generates sparks at an unorganized installation site has a high risk of causing a fire. When replacing it with a new one, it also has the disadvantage that a high voltage power source for the welding work cannot be obtained.

Moreover, the floor inspection opening 3 is suitable for the subsequent mortar 6.
In order to provide a reference surface during filling work, highly accurate leveling is generally required, but in the conventional example, this leveling involves adjusting the welding height of the connecting tool 5 to the reinforcement 2. This work was also a cause of lowering the overall installation efficiency.

The present invention has been made in response to these circumstances, and an object of the present invention is to provide a floor inspection port installation device that does not require welding during installation and is efficient in installation. .

[Means for solving problems]

The present invention, as shown in FIG.
The floor inspection opening 3 is connected to the anchor member 8 via the auxiliary tool 7.

The auxiliary tool 7 has a holding piece part 9 and a mounting piece part IO at both ends thereof, which are arranged at substantially right angles to each other, and is attached to the outer frame 4 of the floor inspection opening 3 at the holding piece part 9. .

The anchor member 8 is formed into a rod shape, and a flange II is attached to the vicinity of its upper end so as to be movable downward.

The auxiliary tool 7 places and holds the attachment piece 10 on the collar 11 of the anchor member 8 by inserting the long hole 12 formed in the attachment piece 10 into the anchor member 8. has been done.

[Created for]

Therefore, in the present invention, when installing the floor inspection port 3, first, an appropriate number of anchor members 8 are planted in the concrete base 1, and then the collar part II attached to the anchor member 8 is moved up and down. Then, the upper surface of the flange 11 is leveled.

Next, the upper end of the anchor member 8 is inserted into the elongated hole 12 formed in the attachment piece lO of the auxiliary tool 7, and the attachment piece Io is placed on the collar 11 and held.

In such a state, the floor inspection port 3 is temporarily installed at the position where it should be installed, so mortar 6 is filled around the outer frame 4 of the hindlimb floor inspection port 3, and the floor inspection port 3 is installed.

At this time, the anchor member 8 is planted and attached to the concrete base 1, so the reinforcement 2 is removed from the concrete base l.
The installation position of the anchor member 8 can be set strictly because the elongated hole 12 is bored in the attachment piece 10 of the auxiliary tool 7 and its position can be adjusted. There is no need to do this, and installation efficiency can be increased.

Furthermore, by moving the flange 11 of the anchor member 8 up and down, it is possible to easily level the floor inspection opening.

A set screw 15 is screwed into the outer frame 4 for secure attachment.

Further, in this embodiment, rounded portions 16 are formed at the upper and lower ends of the holding piece portion 9, and when the auxiliary tool 7 is rotated once in either the left or right direction, the holding piece 9 is inserted into the storage groove 14 of the outer frame 4. After the part 9 is fitted, the auxiliary tool 7 can be easily attached to the outer frame 4 by rotating it with a reflective force.

On the other hand, the elongated hole 12 bored in the attachment piece IO is formed in the shape of a notch that opens at one end of the material, so that an anchor member 8, which will be described later, can be inserted through the opening 17. There is.

By forming the elongated hole 12 in a notch shape in this way,
For example, when the outer frame 4 is heavy, as shown in FIG. 3, it is possible to tilt the outer frame 4 and insert the elongated hole 12 into the anchor member 8 through the opening 17, making the installation work easier. be able to improve.

Further, the anchor member 8 in this embodiment has a biting part 8a formed at the tip and a threaded part 8 at the other end.
A so-called all-anchor with a shape b is used, and the biting part 8a is driven into the hole 18 previously drilled in the concrete base lX1i, and the biting part 8a is fixed with a wedge-shaped tip 8c attached to the tip of the hole 18. 8a can be pushed open and planted on the concrete base 1.
