Description

  The present invention provides a suspension support tool for supporting a supported body through a suspension band below a ceiling surface. The suspension support can be supported with a small number of parts and man-hours. The present invention relates to a technology for making it difficult to remove.

  In air-conditioning work in buildings, factories, warehouses, station buildings, and other buildings, circular ducts (spiral ducts) made of galvanized iron plates that are heavy are used to transport air (fresh outside air, cold air, warm air, exhaust). However, in recent years, the ducts at the end connected to the ceiling outlets, etc. are easily flexible and shorten the work, so they are flexible and lightweight flexible ducts with heat insulating materials are used. It is supported by hanging from the surface.

  In order to suspend the duct from the ceiling concrete surface in this way, conventionally, a dedicated cradle is attached to the upper surface of the duct, and the cradle and the fasteners fixed to the ceiling concrete are tied together by means of suspending. Method (Patent Document 1), the both ends of the first wire surrounding the duct having different linear lengths are inserted into the upper and lower small holes of the first metal plate bent in the shape of a square. Both ends are fixed to the first metal plate, and the end of the straight second number line suspended from the concrete surface and one of the two end parts of the first number line are formed in a dogleg shape. A method of hanging and supporting a duct from a ceiling concrete surface by passing through two small holes in the upper and lower sides of a second metal plate bent at the center and fixing the first and second wires to the second metal plate. (Patent Document 2).

JP-A-8-285359 (2nd page, FIG. 1) Japanese Utility Model Publication No. 58-25193 (page 4, Fig. 1)

  However, in the former method, a dedicated cradle must be provided on the upper surface of the duct in advance, resulting in high costs. In the latter method, the ends of the number wires must be inserted into the two metal plates from the top and bottom, so that work is required. It was complicated.

  As another method, there is a method using an insert and a suspension bolt. That is, the insert is driven into the hole in the deck plate constituting the ceiling surface from above so that the lower part is exposed to the lower side of the deck plate, and then concrete is placed on the upper side of the deck plate. After the concrete has hardened, screw the upper end of the suspension bolt into the lower part of the insert and fix it. Fix the suspension band support bracket to this suspension bolt, and suspend both ends of the suspension band to this bracket. Hold the flexible duct in the middle of the band.

  However, in this method using inserts and suspension bolts, (a) driving the insert into the hole in the deck plate, (b) attaching the suspension bolt to the insert, (c) attaching the bracket to the suspension bolt, ) Four operations of attaching the hanging band to the metal fittings were necessary, and it took time and time for the construction.

  An object of the present invention is to provide a hanging support that does not require such a complicated operation.

In order to achieve the above object, the suspension support of claim 1 of the present invention comprises:
A suspension support tool for supporting the supported body in a suspended manner via a suspension band below the ceiling surface,
A band plate portion formed integrally with a metal plate, a mounting plate portion formed to be bendable on one end side of the band plate portion, and fixed to the ceiling surface from below through a rod-shaped fixing body, and the band plate extending from the other end parts to the mounting plate portion, Rutotomoni a said suspension so can pass through the holes provided at both ends of the band formed hook portion,
In the middle of the hook portion, there is a width slightly wider than the diameter of the hole provided at both ends of the suspension band, and the direction of expanding the hole of the suspension band by the force applied when engaging the suspension band A disengagement restricting portion for restricting movement in a direction in which the suspension band is disengaged from the hook portion in a state where the hook portion is deformed to pass through and the force is not applied,
Both ends of the suspension band are supported and supported by the suspension band on the hook portion on one end side of the strip plate portion that is bent from the attachment plate portion that is fixed to the ceiling surface by the penetration of the rod-shaped fixed body. It is characterized by being able to hold the body.

Moreover, the hanging support tool according to claim 2 of the present invention is the hanging support tool according to claim 1 ,
The detachment restricting portion is formed by a stopper protruding from the lower edge of the hook portion.

Thus, the suspension support according to claim 1 of the present invention is a belt that is fixed to the ceiling surface by the penetration of the rod-shaped fixing body from below and is bent from the mounting plate portion. since supporting the hanging band by one end of the full-click portion of the plate portion, suspended easily without requiring complicated operations can be supported, in the middle of the hook portion, than the diameter of the holes provided at both ends of the hanging band It has a slightly wide width and is deformed in the direction to widen the hole of the suspension band by the force applied when the suspension band is supported and passed through the hook part, and the suspension band is hooked in the state where the force is not applied In the case where the disengagement restricting portion that restricts the movement in the direction away from the portion is provided, the disengagement of the suspension band is less likely to occur because the movement in the disengagement direction of the suspension band is restricted.

Moreover, in the hanging support tool according to claim 2 of the present invention, in the case where the disengagement restricting portion is formed by a stopper projecting from the lower edge of the hook portion, the hooked hanging band has a force from below. The lower end of the hole of the suspension band is in contact with the lower edge of the hook part, and there is always a step between the lower edge of the stopper, so the hole extends beyond the stopper in the direction of removal. It cannot move, and the detachment of the suspension band is less likely to occur.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a hanging support tool 1 according to an embodiment for hanging and supporting a support such as a flexible duct via a hanging band below a ceiling surface formed by placing concrete. .

  As shown in FIG. 1, the suspension support 1 is integrally formed by pressing or the like on a metal flat plate, and can be bent to the upper end side of the strip plate portion 2 extending in the vertical direction. And is provided with a mounting plate portion 3 that is fixed to the ceiling surface from below by penetration of a rod-shaped fixing body. The rod-like fixed body is, for example, a scissors by a hammering machine, screws, nails or the like.

  Incisions 5a and 5b are provided on both sides of the boundary portion 4 between the band plate portion 2 and the mounting plate portion 3, so that the operator can bend at any angle by the hand force at the boundary portion 4. It has become.

  Alternatively, instead of this incision, an elongated hole (not shown) is provided at the center of the boundary portion 4 along the boundary portion 4 so that the operator bends at an arbitrary angle by the hand force at the boundary portion. May be possible.

  In this boundary portion 4, the band plate portion 2 is bent in advance at an angle smaller than 90 ° (for example, 45 °) with respect to the mounting plate portion 3 so as not to interfere with the hammering operation.

  The mounting plate portion 3 has a thickness that allows the scissors to be penetrated by a hammering operation, but a hole or a thin portion having a diameter smaller than the diameter of the scissors is provided in the center of the mounting plate portion 3 so that the scissors can be easily penetrated. Also good.

  The band plate portion 2 is linearly extended in the vertical direction with a constant width, and is provided with a hook portion 6 extending from the lower end of the band plate portion 2 toward the mounting plate portion 3 and capable of supporting both ends of the suspension band.

  The hook portion 6 includes a base portion 6a extending a predetermined distance from the lower end of the strip plate portion 2 in a direction substantially perpendicular to the length direction (vertical direction) of the strip plate portion 2, and the strip plate portion 2 from the tip of the base portion 6a. And a folded portion 6b extending in the direction of the attachment plate portion 3 (upward).

  The vertical width (height) H1 of the base 6a is set to be smaller than the diameter along the length direction of the suspension band of holes 11 and 12 provided at both ends of the suspension band 10 to be described later. I can pass. The horizontal width of the folded portion 6 b is set so that it can pass through the holes 11 and 12 provided at both ends of the suspension band 10.

  Furthermore, the width W of the gap 7 that is vertically formed between the side edge of the band plate portion 2 and the side edge of the folded portion 6b is larger than twice the thickness of the suspension band (for example, 4 Is set to be approximately twice as high).

  A stopper 6c is provided at the lower end of the folded portion 6b. The stopper 6c protrudes slightly below the lower edge of the base 6a. The portion from the position where the upper edge of the base portion 6a and the left edge of the folded portion 6b intersect to the lower end of the stopper 6c constitutes the disengagement restricting portion of this embodiment, and its width H2 is the hole of the suspension band 10 It is set to be slightly longer than the lengths of 11 and 12.

  Therefore, if the folded portion 6b is passed through the holes 11 and 12 of the suspension band 10 and further passed to the base portion 6a, the suspension band 10 is caught by the stopper 6c and cannot pass, but the suspension band 10 is made of synthetic resin and has flexibility. Therefore, when pulled down downward, it is deformed in the direction in which the holes 11 and 12 expand, and can pass through the stopper 6c and pass to the base 6a. After passing through the stopper 6c, unless a strong force is applied downward, the holes 11 and 12 of the suspension band 10 cannot return to the folded portion 6b beyond the stopper 6c, and the suspension band 10 does not come off.

Next, the use of this hanging support will be described.
As shown in FIG. 2, the mounting plate portion 3 of the suspension support 1 held on one hand of the operator from the lower side is pressed against the ceiling surface 30 formed by concrete placement, and placed on the other hand. The soot ejection tip 41 of the gas-type nailing machine 40 is held against the mounting plate 3 from the lower side and hammered, and as shown in FIG. 3, the rod (rod-like fixed body) 42 is mounted on the mounting plate. 3, and the penetration plate 3 is fixed to the ceiling surface 30 by penetrating into the ceiling surface 30 of the concrete 31.
Note that the mounting plate portion 3 may be fixed to the ceiling surface 30 by allowing screws or nails or the like to penetrate the mounting plate portion 3 instead of the ridges and further penetrate into the ceiling surface 30 of the concrete 31.
After fixing in this way, the band plate portion 2 is bent at approximately 90 ° by hand at the boundary portion 4.

  And in this state, as shown in FIG. 4, the folding | returning part 6b of the hook part 6 is allowed to pass through the hole 11 of the one end side 10a of the suspension band 10 for holding a to-be-supported body, and the upper end of the hole 11 is base 6a. The upper end of the lower end is reached and the lower end is pulled down to a position where it abuts against the stopper 6c. Here, the hole 11 of the suspension band 10 is an oval hole having a long axis along the length direction thereof, but may be a rectangle, a circle, or the like. However, it is desirable that the length L along the length direction of the band is maximized.

  As described above, since the width of the folded portion 6b is smaller than the length L of the hole 11, the folded portion 6b passes through the hole 11, but the distance H2 from the upper end of the base portion 6a to the lower end of the stopper 6c is the length of the hole 11. Since it is slightly longer than the length L, it cannot pass as it is.

  However, when the suspension band 10 is pulled down with a little strong force as described above, the upper and lower edges of the hole 11 are elastically deformed in the direction of expanding the hole diameter and pass through the stopper 6c, as shown in FIG. 6a is inserted through the hole 11 at one end 10a of the suspension band 10. If the application of the downward force is stopped after passing through the stopper 6c, the diameter of the hole 11 returns to the original state, so that it cannot pass through the stopper 6c.

  Next, as shown in FIG. 5, for example, a flexible duct 15 is held as an object to be supported by an intermediate portion of the suspension band 10, and the hook portion 6 is inserted into the hole 12 at the other end 10 b of the suspension band 10 as described above. The folded portion 6b is passed, the suspension band 10 is pulled down strongly, and the stopper 6c is passed, so that the base portion 6a is inserted through the hole 12.

  By this operation, as shown in FIG. 6, both ends 10a and 10b of the suspension band 10 are sandwiched between the band plate portion 2 and the folded portion 6b while being overlapped with each other, and the movement in the disengagement direction is restricted. Be supported.

  In this state, even if a force is applied to the flexible duct 15 and the suspension band 10 from below or an external force such as wind is applied, the lower edges of the holes 11 and 12 of the suspension band 10 are below the base portion 6a of the hook portion 6. Since the state where there is a step between the edge and the lower end of the stopper 6c is maintained, both ends of the suspension band 10 cannot move in the direction away from the hook portion 6, and the suspension band 10 is detached. do not do.

  Thus, if the suspension support tool 1 according to the embodiment is used, it is possible to easily suspend and support a supported body such as a duct via the suspension band 10 with less man-hours and with less man-hours. Even if there are many, construction can be done at low cost. Further, since the disengagement restricting portion is formed by the stopper 6c projecting from the lower edge of the intermediate portion of the hook portion 6, the problem that the suspension band 10 is disengaged by a force from below is also solved.

  Further, as described above, the gap W between the band plate portion 2 and the folded portion 6b is sufficiently wider than twice the thickness of the suspension band 10, and the lateral width of the holes 11 and 12 of the suspension band 10 (the longitudinal direction of the band) Is larger than the thickness of the band plate portion 2, the suspension band 10 can rotate in a twisting direction within a relatively wide range while being supported by the hook portion 6. Moreover, it can be twisted and deformed by the flexibility of the suspension band 10 itself.

  Therefore, as shown in FIG. 7, it is possible to support the suspension band 10 in a state where it is twisted by 90 °, for example. By twisting the suspension band 10, the direction of the band plate portion 2 and the flexible support target are supported. Construction can be performed without much concern about the length direction of the duct 15.
