Description

[Detailed description of the invention] The present invention relates to a cross-connection fitting for channel steels that can cross and connect channel steels at a desired angle, and mainly includes a sprinkler water supply pipe arranged in a ceiling pocket. When doing so, it is most suitable for positioning the pipe material support fitting that is fixed to the channel steel and supports the water supply pipe.

Normally, in order to place a sprinkler on a ceiling surface, it is necessary to install the water supply pipe in the ceiling pocket, and conventionally, the installation channels are installed in lightweight channel steel called Noen, which are arranged in rows in the ceiling pocket. Piping work was carried out by directly erecting barrels and other channel steel, and fixing pipe support fittings to support the water supply pipes.

However, recently, due to the demand for beautification of the ceiling surface, so-called recessed sprinklers have been proposed in which the protruding part from the ceiling surface is reduced and the sprinkler body is installed recessed in the ceiling pocket. According to this, a positional relationship occurs in which the pipe material support fitting supports a relatively large diameter coupling that connects the ζ sprinkler body and the water supply pipe, and the conventional pipe material support fitting becomes unusable. It's inconvenient.

In other words, in order to enable the conventionally used pipe support fittings to support the water supply pipe, the two types of channel steels that are installed in an intersecting manner must be installed at appropriate intervals, and the pipe support fittings must be installed. It is necessary to locate the mounting channel above the coupling.

In addition, the intersection angle between the so-called field edge and the mounting channel is
It is desirable to be able to set the settings freely according to the construction situation, and as mentioned above, the channel steel of both the field edge and the mounting channel can be connected and supported while maintaining a certain distance, and at the same time, the channel steel can be set at a desired angle to each other. Currently, it is awaited to provide a connecting metal fitting that can be crossed.

The present invention has been devised in view of the above points, and its purpose is to connect and support channel steels at appropriate intervals, and to allow them to intersect at a desired angle. To provide a cross-connection fitting for channel steel which is capable of forming a cross-connection fitting for channel steel.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. That is, a pair of channel steels 100 and 200 are overlapped with each other at an appropriate crossing angle, and the openings are oriented laterally in the direction of overlap.

00 A mounting plate 5 that abuts the outer surface of the lower side wall 102 and a rim plate 6 that abuts the end face of the side wall 102 are sequentially arranged in a front abbreviated shape, and the other end of the fixed plate 4 is made to correspond to the predetermined spacing. The spacing setting plates 1 having a substantially groove-shaped front surface having a height are arranged in series, and extend from the ends of the spacing setting plates 1 in the direction of the fixed plates 4, and work together with the fixed plates 4 to deepen the channel steel 100. The abutting plates 3 that are pressed in the horizontal direction are arranged in series, and the base of the abutting plates 3 is inserted into one side of the spacing setting plate 1 within the gap in the direction in which the channel steel 100 and 200 overlap each other. The tightening bolt 9 is screwed to the other side so that it can move forward and backward, and the supporting metal fittings A are attached to each other so as to elastically sandwich the other channel steel 200 with the other channel steel 200 inserted therein. A pair of clamping plates 10 that face each other and are biased toward each other, and a connecting lower plate 11 that abuts the upper part of the spacing setting plates 1 are provided. The upper part and the connecting lower plate 11 are pivotally connected to connect the fixing metal fitting A and the supporting metal fitting B.

The fixing fitting A fixed to the channel steel 100, such as a field edge in the ceiling pocket, has a substantially one-cornered shape from the front, and is integrally formed by bending a flexible plate material.

The approximately U-shaped part bent at the front is the interval setting plate 1 located above the channel steel 100, that is, its upper part 2.
c, a pair of opposing side parts 2a, 2b1 and upper part 2c
The abutment plate 3 facing the front side is continuous from one side 2a.

The other side 2b of the groove-shaped back wall 103 of the spacing setting plate 1 is continuous with the fixed plate 4, and the lower end of the fixed plate 4 has a mounting plate 5 facing the abutting plate 3. are continuous, and the edge plate 6 is continuous from the end of the mounting plate 5.

One side 2a of the spacing plate 1. That is, a free hole 7 is bored in the continuous abutment plate 3, and a screw hole 8 is formed in the other side 2b, which is burred and tapped, in the other side 2b that faces this 2a. It is formed.

The play hole 7 and the screw hole 8 are used for screwing a tightening bolt 9 provided with a knob as necessary.

The fixture A is fixed so as to hold the channel steel 100, and the inner surface of the contact plate 3 is connected to the side wall 1 of the channel steel 100.
01, and the fixed plate 4, mounting plate 5, and rim plate 6 hold the back wall 103 and the other side wall 102 of the channel steel 100, and the inner surface of the rim plate 6 is in contact with the end surface of the side wall 102. It is designed to connect and lock.

Also, the height of the interval setting plate 1, that is, the upper part 2C and the contact plate 3
The distance between the cross-connected channel steel 100, 200
It is determined according to the desired arrangement spacing between the two.

That is, by increasing this distance, a large distance can be maintained between the channel steel 100, such as a field edge, to which the fixing metal fitting A is fixed, and the channel steel 200, such as a mounting channel, supported by the supporting metal fitting B, which will be described later. This makes it extremely convenient to use the pipe support fitting U for supporting the water supply pipe T of the sprinkler 8.

This fixing fitting A is formed by bending a strip-shaped plate material, and as shown in the developed view shown in FIG. None, groove #410
It is also effective to encourage the bite to zero.

The fixing fitting A shown in FIG. 7 is made by dividing the contact plate 3 into three to form a strip-shaped upper clamping piece 3b and a lower clamping piece 3c. side wall 101 of
It is designed so that it can be held.

A perspective view of a connecting fitting using this is shown in FIG.

Also, by being rotatably coupled to the fixing fitting A and supporting the other channel steel 200 in an inserted state, one channel steel 10
Specifically, the elastic support means of the support fitting B that cross-connects the channel steel 200 at an appropriate cross angle with respect to 0 is constructed as follows.

That is, as shown in FIGS. 1 to 3, the entire support fitting B is formed of a band-shaped spring steel material into a substantially groove shape, and a pair of opposite sides of the connecting lower plate 11 are inclined inwardly. The clamping plates 10 are arranged in series, and a downward locking claw 12 is provided approximately at the center of the clamping plate 10.
The channel steel 200 which is cut, raised, formed, and placed on the connecting lower plate 11 is clamped and fixed by the elastic force of the clamping plate 10 and the locking pawl 12, the fourth As shown in FIGS. 1 to 5, the locking claw 12 of the same as shown in FIGS. 1 to 3 is omitted, and the clamping and fixing is performed simply by the elastic force of the clamping plate 10, etc. There is.

In any case, the connection lower plate 11 of the support bracket B is rotatably attached to the fixing bracket A using an appropriate means such as a rivet 13, and the channel steel is fixed to both the fixing bracket A and the support bracket B, respectively. 100 and 200 can be crossed at any angle.

In addition, although the fixing fittings A and the supporting fittings B have different names for convenience of explanation, they essentially have the same function in terms of supporting the channel steel 100.200. When used in a pocket, it can be used interchangeably, such as fixing it to the edge of the field with the support metal fitting B, while supporting the mounting channel with the fixing metal fitting A.

In addition, the supporting metal fitting B shown in the figure supports the back wall of the channel steel 200 by positioning it upward or downward, that is, by opening the channel portion upward or downward, and the supporting metal fitting B shown in the figure supports it. By selecting the following, it is possible to achieve the optimal installation condition according to the construction situation at the site.

Although not shown in the drawings, by making the internal space of the support bracket B narrow so that it is vertically long, and by making the clamping plate 10 sufficiently high, the channel portion of the channel steel 200 can be horizontally It is also possible to support it with an opening.

Next, the use of the present invention when arranging the water supply pipe T of a so-called embedded type sprinkler 5 in a ceiling pocket will be explained.

First, the fixing fittings A are fixed to the grooves arranged in parallel to the ceiling surface F, *100, that is, to the edges.

As shown in the figure, the inner surface of the side wall 101 of the channel steel 100 is engaged with the abutting plate 3 of the fixture A, and the fixing part 4 of the fixture A,
The mounting plate 5 and the edge plate 6 are installed so as to hold the channel steel 100, and then the tightening bolt 9 is screwed.
By rotating the opposing sides 2a and 2b of the spacing plate 1, the side parts 2a are pressed and bent, and the channel steel 100 is pressed and fixed at the end face of the contact plate 3.

At this time, if the fixture A shown in FIG. 1 is used, the sharp plate 3a will be press-fitted into the inner wall 103 of the channel steel 100, making the fixation even more reliable.

In addition, in the fixture A shown in FIG. 4, the upper clamping piece 3
(b) Since the lower clamping piece 3c clamps the side wall of the channel steel 100 so as to pass around it, shaking in the vertical direction is particularly effectively prevented.

Next, a rotatable support bracket B coupled to the fixture A
The other channel steel 200, that is, the mounting channel, is held between the plates 10 and 10.
Attaches using the elastic clamping action of the

A pipe support fitting U is fixed to the channel steel 200, which is attached to the support fitting B and serves as a mounting channel, and is approximately U-shaped from the front and has a fixing portion UA and a pipe branch surrounding. The water supply pipe T can be supported (see Fig. 3).

That is, when the channel steel 100 as a field edge and the channel steel 200 as a mounting channel are placed directly orthogonally to each other and the pipe material support fitting U is attached to the channel steel 200, as in the conventional case. , In the case of the embedded type sprinkler 8 which is being provided recently, one sprinkler stored in the ceiling pocket is μs.
Since a coupling V that connects A and the water supply pipe T and has a larger diameter than the water supply pipe T is present near the pipe support portion UB of the pipe support fitting U, the design of the pipe support fitting U must be changed, etc. This causes the inconvenience of being forced to do so.

In the present invention, since the fixing fitting A has the spacing plate 1 for separating the channel steels 100 and 200 by a predetermined distance in the superimposing direction, the height of the spacing plate 1 can be adjusted appropriately. By making this selection, it becomes possible to connect both channel steels 100 and 200 with an appropriate interval, and the position of the pipe material support fitting U fixed to the channel steel 200, which becomes the mounting channel, is also closer to the ceiling surface F than in the past. It can be positioned even higher.

In other words, the channel steel 200 serving as the mounting channel is adjusted according to the vertical change in the coupling position between the conventional sprinkler 8 that protrudes into the room from the ceiling F and the embedded sprinkler 8. If space is secured with the spacing plate 1 and abutment plate 3 of the fixture A so that it is disposed upward, the pipe support part UB of the pipe support fixture U can support the outer circumferential surface of the water supply pipe T as before. Therefore, the existing pipe material support fitting U can be used continuously without making any changes.

The fixing fitting A that fixes one channel steel 100 in a holding manner is
Fixed plate 4 that comes into contact with the outer surface of channel steel 100) 103
At one end, a mounting plate 5 that abuts the outer surface of the lower side wall 102 of the channel steel 100 and a rim plate 6 that abuts the end face of the side wall 102 are successively arranged in an L-shape when viewed from the front, and at the other end of the fixed plate 4, groove shape;
51oo, 2o.

Distance setting plates 1 having a generally groove-shaped front surface having heights corresponding to mutual separation distances are arranged in series, extending from an end of the spacing setting plates 1 in the four directions of the fixed plates, and cooperating with the fixed plates 4. Channel steel 1
Abutment plates 3 are provided to pinch 00 in the depth direction, and
Within the gap between the channel steels 100 and 200 in the overlapping direction, the base of the contact plate 3 can be seen, and the tightening bolt 9 inserted through one side 2a of the spacing setting plate 1 can be moved forward and backward into the other side 2b. Since it is screwed and hollowed, it is fixed to the channel steel 100 in a state where it holds the channel steel 100 whose openings are oriented laterally in the overlapping direction.

The mounting plate 5 and the edge plate 6 are placed 100 from below the channel steel 100.
In addition, the channel steel 100, which is usually used as a fence, has an opening directed to the side and a ceiling surface F installed below.
Even if there is no working space below, the fixing bracket A itself has no moving parts when set, and the setting of the fixing bracket A to the channel steel 100 is extremely easy and easy to handle. is most convenient.

Not only that, the tightening bolt 9 is always aligned in the direction of insertion and assembly with respect to the distance setting plate 1, and furthermore, the advancing and retreating direction of the screw fastening is always along the direction perpendicular to the superimposing direction, which improves workability. It helps greatly in improving.

In addition, due to the cooperation of the contact plate 3 and the fixed plate 4, the groove type #4
Squeezing 100' in the depth direction means channel steel 100'
At this time, the abutment plate 3 becomes parallel to the side wall 101 of the channel steel 100, and the tightening bolt 9 is moved outward from the side wall 1. Since the groove steels 100 and 200 are placed in the same position, the movement of the fixing fitting A itself in the overlapping direction of the channel steels 100 and 200 can be prevented by
9 can be prevented and suppressed.

That is, not only can the abutting plate 3 and the tightening bolt 9 provide a clamping and fixing effect on the channel steel 100, but also the spacing setting plate 1 can be directly used to maintain the spacing. Moreover, it functions extremely effectively, and the fact that it can be used for both purposes greatly contributes to simplifying the entire structure and providing it at a low cost.

The support fitting B includes a pair of opposing clamping plates 10 that are tilted toward each other so as to elastically clamp the other channel steel 200 with the other channel steel 200 inserted therein; Since the connecting lower plate 11 that abuts the upper part 2c of the spacing setting plate 1 is provided, the channel steel 200 can be firmly supported and fixed in the inserted state, and the insertion work is performed without the elasticity of the clamping plate 10. It can be performed with one touch against force, and even if this type of work is often carried out at high places, it can ensure safe work.

In addition, the opening of the channel steel 200, which serves as a mounting channel for installing the sprinkler 8, can be made into various structures by selecting which direction it faces depending on the situation at the site, which is extremely convenient. be.

In the ceiling pocket, a plurality of channel steels 100 are installed as a field edge.
The connecting fittings of the present invention are fixed to the respective connecting fittings, and the other channel steel 200, which becomes the mounting channel, is made to intersect with the channel steel 100 at a desired angle and supported by the support fitting B of each connecting fitting. ! ! 1100.200 are connected in a cross shape.

Therefore, according to the present invention, since the fixing metal fitting A and the supporting metal fitting B are made relatively rotatable, the groove-shaped #A100.200 that is firmly supported by both metal fittings A and B can be
Depending on the site situation, they can be connected perpendicularly, in parallel, or intersectingly at a specific angle.

Its versatility is extremely large.

In addition, since the channel steels 100 and 200 can be connected to each other at a constant interval, it is convenient to use the pipe material support fitting U to support the water supply pipe T when installing the sprinkler 8, as described above. In addition, when installing various wiring devices such as a wiring box to the groove-shaped mounting channel 200, the installation space for the various wiring devices can be reduced by providing a sufficient distance between the groove-shaped steel 200 and the ceiling surface F. It is possible to ensure that
