Description

[Detailed Description of the Invention] The present invention relates to a foundation hardware used for constructing a rising portion that serves as a foundation for a television antenna or the like.

For example, when installing a communal TV antenna on the roof of a condominium, etc., generally a rising part is provided on the roof floor, anchor bolts are buried in this in advance, and the base plate of the antenna is fixed to these bolts with nuts. By doing so, the antenna was supported on the rising part.

Then, this rising part and the waterproof finishing rising jaw are cast on site.

Anchor bolts are fixed to the upright frame and reinforcing bars by aligning them on site.

Further, the space between the base plate of the antenna and the sloping upper surface of the rising portion is filled with mortar, and the base of the rising portion is chamfered to form a waterproof base cut portion.

However, according to this conventional example, the molding of the waterproof-pasted rising jaws protruding from both sides of the upper end of the rising part is troublesome, and the construction is complicated because the gap between the foundation plate and the rising part is filled with mortar. It has become.

Also, the positioning of the anchor bolts is done on-site, making it difficult to achieve accuracy.

The object of the present invention is to provide a basic hardware that can eliminate the above-mentioned drawbacks.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes basic hardware, and this basic hardware consists of a rising formwork frame 2 which also serves as a waterproof base, and anchor bolts 3.

The frame body 2 is formed of a steel plate in the shape of a picture frame, and the outer periphery thereof has an outwardly inclined inclined portion 2a.

A rising portion 2b is provided at the edge of the upper end opening 4 of the frame body 2.

At each corner of the opening 4, there is an L-shaped support metal fitting 5.
・The hardware is welded to the inner corner of the rising portion 2b.

Also, the anchor bolts 3... are hung vertically from the frame 2, and the upper ends of the anchor bolts are the supporting hardware 5...
It is fixed to...

Anchor bolt 3... At the lower end, there is a metal fitting 6 for positioning this anchor bolt on the floor formwork.
This is the installation.

In the example shown in the second and third figures, the metal fittings 6... are formed into a bridge shape, and each metal fitting is attached to the anchor bolt 3 by a level adjustment nut 7...
It is installed so that its position can be adjusted.

Note that the metal fittings 6 may be fixed to the anchor bolts 3 without using the level adjustment nuts.

6a is an anchor bolt insertion hole, and 6b is a nail hole.

Next, how to use the basic hardware 1 will be explained based on FIG. 4.

First, each anchor bolt 3... is erected on the floor formwork 8, and the hardware 6... is attached to the nail 9...
Fix it to the floor formwork and position the anchor bolts.

By fixing the anchor bolts 3, the frame body 2 is also positioned above the floor formwork 8.

Then, if necessary, adjust the level by turning the adjusting nut 7 as appropriate.

Then, by pouring concrete through the opening 4 (FIG. 2) of the frame 2 and hardening it, a rising portion 10a is formed together with the concrete floor 10, and this rising portion and the frame 2 are integrated. be converted into

Thereafter, asphalt waterproofing is applied to the upper surface of the concrete floor 10 and the outer circumferential surface of the frame 2 to form a waterproof layer 11.

Then, nails 13 are driven into the upper end plane of the frame 2 through the presser plates 12 toward the rising portion 10a, and the waterproof layer 11 is held down. Completed construction.

Therefore, the frame body 2 has the functions of a waterproof base and a rising formwork.

In order to attach, for example, a television antenna 14 to the rising portion 10a formed in this way, the base plate 15 is placed on the upper surface of the rising portion, and the nut 16...
Fix it to the upper end of anchor bolt 3 with...

Then, an elastic sealing 17 is applied between the plate 15 and the anchor bolt 3.

In addition to the antenna, a lightning rod, a water tank, or other appropriate equipment may be attached to the rising portion 10a.

As described above, according to the present invention, the frame body for waterproof standing formwork and the anchor bolt are integrated, so there is no need for conventional formwork, and time-consuming formwork and dismantling work are required. Therefore, the construction of the rising part is extremely easy.

The anchor bolt positioning work is easy and the positioning accuracy is improved.

For example, there is no need for filling mortar between the base plate and the rising portion of the antenna, which simplifies the work, and has various practical effects.
