Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame jig used for the frame of a gutter provided under the floor for storing various types of piping, wiring, etc.

In recent years, mechanization has been attempted in offices, factories, etc.
Computers and other electronic devices began to be used.

In addition, various types of air conditioning equipment have been introduced to improve the working environment and maintain and manage electronic equipment.

Therefore, in order to operate these devices, 01 is installed under the floor.
11mW, and various piping, wiring, etc. are arranged in the 01lI groove, but in order to avoid hindrance to work, it is necessary to provide a gutter cover at the side gutter opening. Therefore, the upper edge of the gutter opening had to be covered with a frame (outer frame).

By the way, in order to construct the side gutter, a pair of outer frames are arranged at intervals equal to the width of the side gutter, and one end of the anchor fitting is fitted into a mounting groove formed on the outside of the outer frame. , and the other end was fixed to the connector around the side gutter.

However, when a pair of outer frames are self-layered to determine the gap between gutters, the outer frames themselves are often long.
Therefore, it was difficult to maintain a constant distance between the opposing outer frames. In some cases, opposing outer frames are not installed parallel to each other, or a pair of opposing outer frames have a height difference, or are at different levels from each other.

As a result, there was an inconvenience that looseness occurred between the outer frame and the lid body1.In order to eliminate this inconvenience, a framework that can maintain the opposing outer frames at a constant interval during measurement and construction was developed. A jig became necessary.

Therefore, this invention consists of a horizontal connecting rod and a pair of left and right fixing devices that are fixed to both H5Y frame members. Both ends are hung down to form a vertical inner and outer flange, and the lower end of the vertical inner flat is formed with a locking pawl that is locked to the lower flange of the outer frame. A side gutter jig is formed with a locking pawl that locks on the upper flange of the frame, and furthermore, an insertion hole into which a horizontal connecting rod can be inserted is formed at each opposing horizontal position on the upper part of the inner and outer flanges. By providing a tool, the opposing outer frames can be held at a constant interval, making installation and width adjustment easy, and also making it possible to firmly hold the outer frames.

Akira Hongen's framework jig is composed of a horizontal connecting rod 1 and a fixture 2 for fixing the horizontal connecting rod 1 to an outer frame 3. As shown in FIG. 1, the horizontal connecting rod 1 is constructed by raising both ends of a metal horizontal plate-like bottom plate 1a to form a side plate 1.
The horizontal connecting rod 1 is not a metal scale, but a hard one.
It may be formed from a material made of tt fat.

A pair of left and right fixing devices 2 for fixing this horizontal connecting rod 1 to the outer frame 3 are made of metal, and as shown in FIG. having a part 2b,
Both left and right ends of this horizontal main body portion 2b are suspended to form a vertical inner flange 2C1 and a vertical outer flange 2d8.Furthermore, the lower end of this vertical inner flange 2C is laterally protruded inward to form a locking claw 2e. The locking claw 2e is adapted to be locked with the lower flange 3C of the outer frame 3, and the lower yiAi of the vertical outer flange 2d is laterally protruded inward to form the locking claw 2f. The locking claw 2f is configured to lock with the upper flange 3b of the outer frame 3.

Upper portions of the vertical inner and outer flanges 2c and 2d are cut horizontally at opposing positions to form insertion holes 2.
g is provided.

The vertical opening dimensions of this insertion hole 2g are slightly larger than the vertical dimensions of the side plate 1b of the horizontal connecting rod 1.
The comb is easy to insert. The horizontal connecting rod 1 and the fixture 2 are fixed by the fixing bolt 2a.

The outer frame is fixed to the above-mentioned framework jig, and has a main edge 3a that slopes outward from the bottom to the top, as shown in FIG. The upper end protrudes outward in the transverse direction, and the protruding end hangs down to form an upper flange 3b, and this upper flange 3b is adapted to engage with the locking claw 2f of the outer flange of the fixture.
Further, a lower flange 3c is formed below the main edge 3a to project laterally inward, and a trap is formed so that the locking claw 2e of the inner flange of the fixture is locked on the lower surface of the lower flange 3c. There is.

Next, a method of constructing the outer frame 3 in a side gutter using the framework jig having the above-mentioned configuration will be explained.

First, a required pair of outer frames 3 are assembled by connecting the outer frames 3 with corner fittings or joint fittings.

The assembled pair of outer frames 3 are opposed to each other in parallel, and fixtures 2 are fixed to the opposed outer frames 3 at appropriate intervals in the length direction of the outer frames 3. This fixing method is shown in Figure 2.
As shown in Fig. 3, the locking claw 2e of the vertical inner flange of the fixing device is locked with the lower flange 3C of the outer frame, and at the same time, the locking claw 2f of the vertical outer flange of the fixing device is engaged with the upper part of the outer frame. It is engaged with the flange 3b. As a result, the outer frame 3 is held between the vertical inner and outer flanges 2c and 3d of the fixture.

Next, after inserting the horizontal connecting rod 1 into the insertion holes 2g formed at opposing positions in the upper parts of the vertical inner and outer flanges 2c and 2d of the fixture 2 to which the outer frame 3 is fixed,
By sliding the fixture 2 on the horizontal connecting rod 1, adjusting it to the required width, and tightening the fixing bolt 2a screwed into the horizontal main body 2bK of the fixture, the horizontal connecting rod 1 and the outside are connected. The frame 3 can be fixed by a fixture 2, so that the outer frame 3 is clamped on both sides by vertical inner and outer flanges 2c, 2a of the fixture, and its upper and lower ends are connected to MWe horizontal connecting rods 1. The lower end of the frame 3 is held between the locking claws 2e and 2f of the vertical inner and outer flanges of the fixture (Fig. 4), so that the outer frame 3 is held so as to be surrounded from all sides.

The adjustment method mentioned above is to align the lid body 4 (Fig. 5),
There is a way to measure it with a gauge.

In order to attach the outer frame 3, which is held at a constant interval by the horizontal connecting rods 1, to the open end of the side gutter, it must be fitted into the mounting groove on the outside of the outer frame 3, as shown in Figure 84. Anchor metal fittings 6 are welded and fixed to metal reinforcing bars 7 embedded in a concrete thin part 5a of a side gutter 5 while adjusting the height of the outer frame 3. After complete welding, the framework jig consisting of the horizontal connecting rods 1 and fixtures 2 is removed, and mortar 8 is filled between the concrete base 5a and the outer frame 3, as shown in FIG. Finish.

The main body has a horizontal main body, and both ends of the horizontal main body are hung down to form vertical inner and outer flanges, and the lower ends of the vertical inner and outer flanges protrude laterally inward to form locking claws. , both sides of the frame material are arranged vertically inside and outside If! By clamping the I flange and clamping the top F of the frame by the locking claws, the frame is surrounded on all sides, so even if the fixing bolts are loosened, the fixture will not separate from the frame. .

As a result, in order to adjust the width, loosen the fixing bolt,
When sliding the fixture and the connecting rod, even if the fixing bolt is loosened, the fixture will not separate from the frame material, so the fixture will not fall off the frame material like in conventional ones. Therefore, there is no need for a worker to hold the fixture, and the work can now be done easily by one person.

In addition, since the frame is installed around the four sides of the frame, the fixings are not bent diagonally, unlike those that are installed simply by straddling the frame, and the frame and the horizontal connecting rod can be installed at right angles. , it became possible to perform accurate construction.
