Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steady rest structure for suspending and supporting a suspended body such as a fan duct on a ceiling.

[0002]

2. Description of the Related Art When a duct or the like is installed on a ceiling in a factory or the like, as shown in FIG. 4, a support member (22) made of long steel or the like is provided on both sides of the duct (21) at appropriate intervals. ) Are arranged side by side, and the upper end of the support member (22) is fixed to the ceiling (24) by the anchor (23) so that the duct (21) is supported in a suspended state.

However, if it is left as it is, the duct (21) may vibrate in the event of an earthquake or the like to damage other adjacent pipes. Therefore, conventionally, as shown in FIG.
Attach the fixture (26) to the lower end of each support (22), attach one end of the wire (27) to this, and fix the other end to the ceiling with the anchor (28). By tightening the wire (27) with a turnbuckle (29) provided at an appropriate position, a counterforce is applied to each support member (22) to prevent lateral deflection of the duct (21).

[0004]

As described above, conventionally,
The upper end of each wire (27) is placed on the ceiling (24) with an anchor (28), but since the ceiling is generally made of concrete, it requires complicated work to place the anchor (28). . Further, since each wire (27) requires parts such as the fixture (26) and the turnbuckle (29), the number of parts is large and the parts cost is high. Therefore, in the conventional structure,
Construction costs tended to soar. Moreover, the worker
When anchoring the wire (27), it is necessary to take an unreasonable working posture while facing upward on a narrow scaffold,
Another problem was that workers were forced to overwork.

Therefore, it is an object of the present invention to provide a steady rest structure which can be constructed at low cost and which can reduce the work load on the operator.

[0006]

In order to achieve the above object, in the present invention, a suspension is supported in a suspended state via a plurality of support members arranged in parallel on both sides of the suspension.
Between the pair of support members that are separated from each other in the width direction and the length direction of the hanging body, a connecting member that is expandable and contractible and whose entire length can be fixed to a desired length is provided between the upper end portion of one support member and the other. The lower end portion of the support member is connected to be diagonally arranged, and both end portions of the connecting member are engaged with both support members.

In this case, it is desirable that a pair of connecting members be arranged so as to intersect with each other and that both be fixed to each other at the intersection.

The steady-state connecting member according to the present invention is for preventing lateral shake of a suspended body which is supported in a suspended state by a plurality of support members arranged side by side, and is expandable and contractible. The entire length can be fixed at a desired length, and engaging means capable of engaging with the support material is provided at both ends.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a plurality of support members (2) are juxtaposed on both sides of a suspension body (1) including a duct with appropriate intervals. This support material (2) is a long steel material having an outer peripheral surface with threads formed over its entire length, and its upper end is fixed to a ceiling (base member) (4) by an anchor (3) and its lower end is It is fixed to the bracket (5) mounted on the side surface of the duct (1) using a nut or the like.

Among the supporting members (2), two connecting members (6) and (7) are arranged so as to intersect with each other between four supporting members (2) having a positional relationship that draws a rectangle. To be done. Specifically, of the four support members (2), a pair of support members separated in both the width direction and the length direction of the duct (1),
That is, the first connecting member (6) is arranged between the two supporting members (2) located on the diagonal line, and the second connecting member (7) is arranged between the remaining two supporting members (2) to form the first connecting member (7). It is arranged so as to intersect the connecting member (6). Both connecting members (6) and (7) are arranged obliquely so as to connect the upper end of one supporting member (2) and the lower end of the other supporting member (2), and both end parts thereof are both connected. It is engaged and fixed to the support member (2) by an engaging means (14) described later.

Both connecting members (6) and (7) are shown in FIG. 2 (a).
As shown in (b), the inner member (10) is slidably fitted inside the outer member (9). The outer member (9) is formed of a long steel material having a substantially U-shaped cross section. Both side edges of the outer member (9) are bent inward to form a bottom plate (9b), which secures strength and prevents the inner member (10) from falling off, and moreover, the inner member (10). The edges of both sides prevent the operator from being injured. The inner member (10) is made of a long steel material having a U-shaped cross section, and has an outer size that can be accommodated inside the outer member (9). Slotted holes (9a) (10a) are formed along the longitudinal direction of both the outer member (9) and the inner member (10). Double slot (9a)
The bolt (11) is inserted from the inside into (10a), and the wing nut (1
2) is screwed. With the above configuration, the wing nut (1
By loosening 2) and pulling out the inner member (10) from the outer member (9) or pushing it into the outer member (9), the connecting members (6) and (7) can be expanded and contracted. . Further, by tightening the wing nut (12), the total length of the connecting members (6) and (7) can be fixed to a desired length.

At both ends of the connecting members (6) and (7), engaging means (14) which can engage with the supporting member (2) and can be attached to and detached from the supporting member (2) are provided. This engaging means (14)
As shown in FIG. 3, the inner member (10) and the outer member (9) (however, the outer member (9) is illustrated in the drawing) are cut and raised in the vicinity of the center of both ends ( 15) is provided and this is erected sideways, and this cut and raised (15)
An insertion hole (17) having an inner diameter that allows the support material (2) to be inserted is formed continuously with the insertion space (16) formed by. After inserting the support member (2) into the insertion hole (17) through the insertion space (16), cut and raise the cut member (15) to the original horizontal position as shown by the arrow to insert the support member (2) into the insertion hole. (17) It is possible to reliably prevent coming off from.

The steady rest structure according to the present invention is constructed as described above. The steady rest structure is appropriately provided at a plurality of positions in the length direction of the duct (1).

The procedure for assembling the steady rest structure will be described below.

First, the first and second connecting members (6) and (7), which have been contracted in advance, are diagonally arranged between the supporting members (2) located diagonally. Next, both connecting materials (6)
(7) is extended to insert each support member (2) into the insertion hole (17), and then the wing nut (12) is tightened to fix the length of the connecting members (6) and (7). Finally, the cut-and-raised part (15) is returned to the original position so that both ends of the connecting members (6) and (7) are engaged with the supporting members (2).

With this structure, since each support member (2) is integrated with the diagonal support member which forms a pair with the support member (2), the rigidity of both support members (2) is set in the width direction of the duct (1). It can be improved bidirectionally in the length direction. Therefore, it is possible to exert a sufficient counter force against the horizontal external force generated by an earthquake or the like, and it becomes possible to prevent or reduce the lateral shake of the duct (1). Further, since the inner edges of the insertion holes (17) provided at both ends of the connecting members (6) and (7) engage with the threads of the supporting member (2), the supporting member (2) and the connecting member (6) ( 7) and are more firmly fixed, and a more effective steady rest effect is exhibited.
At this time, as shown in FIG. 1, if the connecting members (6) and (7) are fixed at the intersections thereof with the fastening members (18) such as bolts, the steady rest effect can be expected to be further improved.

As described above, according to the present invention, the wire (27) used in the conventional structure (see FIG. 5) is unnecessary while exhibiting a sufficient steady rest effect, so that the upper end of the wire is anchored to the ceiling. The steps to be performed can be omitted, and parts such as a fixture and a turnbuckle are unnecessary. Therefore, the construction procedure can be simplified, the number of parts can be reduced, and the overall construction cost can be kept low. In addition, the work environment is improved because it is not necessary to work while facing upward.

In the above description, a duct is exemplified as the suspension body (1), but the present invention is not limited to this, and is similar to a long member of any shape that is suspended and supported on the ceiling (4). Is applicable to. Although FIG. 1 illustrates the case where two connecting members (6) and (7) are arranged between four supporting members (2), one of the connecting members is omitted and one connecting member is omitted. You may use only the connection material of this.

[0020]

As described above, according to the present invention, since the wire used in the conventional structure is unnecessary, the step of anchoring the upper end of the wire to the ceiling can be omitted, and the parts such as the fixture and the turnbuckle can be omitted. Becomes unnecessary. Therefore, the construction procedure can be simplified, the number of parts can be reduced, and the overall construction cost can be kept low. Furthermore, it is not necessary to work while facing upwards,
Work environment improvements are also achieved.
