JP7179277B2 - Fixed support leg for piping - Google Patents

Description

TECHNICAL FIELD The present invention relates to a fixed support leg for piping, and more particularly to a fixed support leg for piping that is compatible with pressing concrete.

A pipe stand as an example of conventional fixed-type support legs for pipes is disclosed in, for example, Japanese Patent Application Laid-Open No. 11-132361 (Patent Document 1). According to Patent Literature 1, a pipe frame is installed between pipe covers that are adjacent to each other. A pipe frame is composed of a pair of leg members, a connecting member that connects the leg members, and a cover member. The flange of the pipe cover that uses the air conditioning duct is connected to the leg member and the cover member. As a result, we have improved the pipe stand that supports the pipe cover that protects the refrigerant pipes that extend to the roof, simplified the design of the pipe cover equipment, and improved the installation workability of the pipe cover, thereby reducing costs. At the same time, it makes it possible to shorten the construction period.

Japanese Patent Application Laid-Open No. 11-132361 (abstract, etc.)

A conventional fixed support leg for piping is configured as described above. In such a configuration, a pair of supporting legs are generally installed on a roof or the like via fixed legs, and the waterproof layer is stretched under the fixed legs, so that when the waterproofing is renewed, the fixed legs are temporarily suspended. It is necessary to carry out the movement and the restoration work separately, which increases the cost. It should be noted that the method in which the waterproof layer is not stretched under the fixed leg and the end of the waterproof layer is pushed against the fixed leg is not recommended because the reliability of the waterproof performance is inferior. It is also conceivable to support the pair of supporting legs with concrete blocks, but this is not preferable because the weight increases.

The present invention has been made to solve the above-mentioned problems, and is a fixed support leg for piping that is lightweight, does not require extra costs for waterproofing renewal, and is capable of more reliable waterproofing. intended to provide

A fixed support leg for piping according to the present invention is fixed to an installation portion provided outside. The fixed type support leg for piping includes a pair of bolts that hold a horizontal member on which the pipe is placed. A waterproof structure is provided around the rising portion from the installation portion of the bolt.

Preferably, it includes a pair of connecting members that can be installed so as to protrude from the installation portion, the pair of connecting members are installed by on-site construction using anchor bolts, and the pair of bolts are provided on the connecting members.

More preferably, the horizontal member has a rectangular vertical surface, a flange portion at the upper end portion of the vertical surface in the vertical direction, and the bolt penetrates the flange portion at the upper end portion.

The horizontal member may have a rectangular vertical surface, a flange portion at the lower end portion of the vertical surface in the vertical direction, and a pair of bolts passing through the flange portion at the lower end portion.

Preferably the bolt is a fully threaded bolt.

The fixed support legs for piping according to the present invention do not use concrete blocks. In addition, the pair of bolts that hold the horizontal members for supporting the pipes are installed on-site using anchor bolts, and since they stand up from the installation part, waterproofing work can be done around the bolts.

As a result, it is possible to provide a fixed support leg for piping that is light in weight, easy to construct, inexpensive to renew waterproofing, and capable of more reliable waterproofing.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a fixed support leg for piping according to one embodiment of the present invention, FIG. 2(A) is a front view, and FIG. FIG. 3 is a side view indicated by arrows IIB-IIB, and FIG. 3 is a perspective view showing an installation state of the fixed pipe support leg 10 when the fixed pipe support leg is installed in an installation section 30 such as a rooftop. FIG. 4 is a cross-sectional view showing the waterproof structure of that portion.

1 to 3, a fixed pipe support leg 10 according to this embodiment includes a pair of connecting members 11a provided on an installation portion 30 for connection to an installation portion 30, such as a rooftop. , 11b, bolts 12a and 12b provided at the upper ends of the connecting members 11a and 11b and extending in the vertical direction, and a horizontal member 13 fixed to the bolts 12a and 12b for placing the pipes. The connecting members 11a and 11b are cylindrical and fixed to the installation portion 30 with male threaded anchor bolts. The bolts 12a, 12b and the connecting members 11a, 11b are integrally provided. The length of the connecting members 11a and 11b is preferably at least 50 mm or longer.

The horizontal member 13 is a metal plate member having a U-shaped cross section, having a rectangular vertical surface 13b elongated in the width direction and flange portions 13a and 13c at the upper and lower ends. A pair of notch holes 14a, 14b and 14c, 14d are provided in the upper and lower flange portions 13a, 13c near both ends in the width direction of the rectangular vertical surface 13b, through which the bolts 12a, 12b pass. do. The bolts 12a and 12b are provided with nuts 15a and 15b and nuts 15c and 15d for sandwiching the upper and lower flanges 13a and 13c in order to position the upper and lower flanges 13a and 13c in the height direction. Nuts 16a, 16b and 16c, 16d are provided to sandwich 13c.

Although the bolts 12a and 12b are shown here as fully threaded bolts, threads may be provided only at necessary positioning locations.

Also, the notch hole may not be provided.

When adjusting the vertical position of the horizontal member 13, the positions of these nuts 15a to 15d and 16a to 16d are adjusted.

A pair of elongated through-holes 17a and 17b are provided in the flange portion 13b at the upper end. A pipe 25 is installed. Here, the pipe 25 and the U-shaped bolt 26 and nuts 27a and 27b for fixing it are indicated by dashed lines.

Here, the through holes 17a and 17b for attaching the U-shaped bolt 26 and the nuts 27a and 27b for fixing the pipe 25, the U-shaped bolt 26 for fixing it, and the nuts 27a and 27b are shown in FIG. 2, there is no need to provide a through-hole at a position aligned with the position of the U-shaped bolt 26 in advance. Also, when using a general-purpose angle material with elongated holes at regular intervals for fixing the U-shaped bolts 26, etc., it is necessary to prepare it at the site, but such a thing is unnecessary. Therefore, installation of piping and the like becomes easy.

Furthermore, if the pipes to be attached here are limited to ventilation pipes that are mainly used in housing complexes, it becomes possible to further limit the widthwise dimension of the elongated holes.

Moreover, the through holes 17a and 17b are preferably provided on the vertical surface 13b side rather than the center of the piping support direction of the flange portions 13a and 13c at the upper and lower ends. This is because when the nuts 27a and 27b are tightened, the warp of the flange portions 13a and 13b decreases as the through holes 17a and 17b are closer to the vertical surface 13b.

As shown in FIG. 3, the connecting member 11 is fixed to an anchor bolt as will be described later. They are provided at intervals of 180 degrees. In addition, the position and shape of this notch part are arbitrary.

Instead of the horizontal member 13 being a metal plate having a U-shaped cross section, a pair of angles arranged vertically with a gap therebetween is used, and one surface of each angle constitutes one surface. A horizontal member may be configured by arranging the bolts 12a and 12b as shown. In this case, if the distance between a pair of angles is large, braces may be provided to increase the strength of the cross members. FIG. 7 shows a diagram corresponding to FIG. 2 in such a case.

Next, the waterproof structure of the installation portion will be described with reference to FIG. Referring to FIG. 4, connecting members 11a and 11b are fixed to installation portion 30 by externally threaded anchor bolts that can be installed on site. The installation part 30 is waterproofed, but since the connecting member 11 is cylindrical and stands up from the installation part 30, the waterproof part 31 can be raised around it. Here, the waterproof part 31 includes a waterproof sheet 32 and a steel plate 33 provided thereunder, and waterproofing is performed using the waterproof sheet 32 surrounding the connection member 11 .

The steel plate 33 may be omitted depending on the waterproof specifications.

Incidentally, in the vicinity of the upper end of the waterproof sheet 32 of the connecting members 11a and 11b, the waterproof sheet 32 may be firmly fixed to the connecting members 11a and 11b with a stainless steel band . A bolt 12 is embedded in the upper ends of the connecting members 11a and 11b, and a nut 12c is provided to fix the position of the bolt.

Between the nut 12c and the upper end of the connecting member 11, a shed 36 having a diameter larger than that of the upper end of the connecting member 11 is provided. A member 35 is provided to prevent rain or the like from entering between the outer periphery of the connecting member 11 and the waterproof sheet 31. - 特許庁

Note that the steel plate 33 may be fixed to the installation portion 30 with fixing screws 41 and 42 .

As described above, in this embodiment, concrete blocks are not used for laying pipes. Therefore, it is possible to reduce the weight, and since the connecting member is installed on site using anchor bolts and rises from the installation portion, a waterproof layer can be raised around it.

As a result, the weight can be reduced, the construction work can be simplified, and the waterproofing can be renewed without cost and more reliable waterproofing can be achieved.

Next, another embodiment of the horizontal member will be described. 5A and 5B are diagrams showing another embodiment of the horizontal member shown in FIG. 1. FIG. 5A and 5B correspond to FIGS. 1A and 1B of the previous embodiment. Referring to FIG. 5, in this embodiment, two L-shaped steel plates 20 and 21 are used as horizontal members so that their lateral projections 20b and 21b face the same direction at both upper and lower ends. They are arranged and connected by positioning bolts and nuts 18a and 18b at both ends of the central portion in the vertical direction.

As shown in FIG. 5, two L-shaped steel plates 20 and 21 are provided with a pair of grooves 22a and 22b and 23a and 23b extending in the vertical direction near both ends in the width direction. The distance between the protruding portions 20b and 21b can be adjusted.

Other than these points, it is the same as the previous embodiment, so the same reference numerals are given to the same or similar portions as in the previous embodiment, and the description thereof will be omitted.

Next, another embodiment of the anchor bolt will be described. FIG. 6 is a cross-sectional view showing a female threaded anchor 28 as another embodiment of the anchor bolt. Referring to FIG. 6, here, a female threaded anchor 28 is provided on the surface of an installation portion 30 made of concrete, for example. This anchor 28 has an internal thread into which the bolt 12 can be screwed. In this case, the connecting portion 11 can be omitted, so the configuration becomes simpler.

Waterproof construction in this embodiment will be described. FIG. 7 shows the state of waterproofing construction in this embodiment (FIG. 7A), and the state of waterproofing construction when the same waterproofing construction is applied to the configuration shown in FIG. 4 (7B). 5 is a cross-sectional view corresponding to FIG. 4 showing .

Referring to FIG. 7A, in this embodiment, waterproof construction is performed using coating film waterproofing. Coating film waterproofing is performed by applying a highly viscous liquid waterproofing material to the waterproof surface. As shown in FIG. 7(A), in this example, a female threaded anchor 28 is driven into an installation portion 30 such as concrete, the bolt 12 inserted therein is fixed with a nut 12c, and a triangular shape is formed so as to cover the outside thereof. A shaped seal 38 is provided and a waterproofing film 37 is provided on its outer surface. The height of the coating film waterproofing 37 may be several cm to 10 cm from the installation portion 30 .

As described above, even when the female screw type anchor 28 is used, it is possible to easily perform preventive construction by means of a waterproof coating film. In this case, since the bolts 12 are thin, waterproofing with a waterproof sheet as shown in FIG. 4 is not possible.

A similar waterproof construction can be used in the previous embodiment as well. FIG. 7(B) shows a case where a similar waterproof construction is used in the previous embodiment shown in FIG. Referring to FIG. 7(B), in this case, a bolt 12 is inserted into the upper end of a connecting member 11 fixed with a male threaded anchor bolt, and the lower end of the connecting member 11 is tapered downward. It is sealed with seal 38 . A coating film waterproofing 37 is provided up to the vicinity of the upper end of the connecting member 11 to cover the seal 38 .

Next, another embodiment of the horizontal member will be described. Instead of a metal plate having a U-shaped cross section, the horizontal member 13 is formed by a pair of angles arranged with a vertical interval so that one surface of each angle constitutes one surface. A set of cross members 24a, 24b may be arranged on the bolts 12a, 12b. In this case, if the distance between a pair of angles is long, braces 24c may be provided to increase the strength of the horizontal member (shown only in FIG. 8(A)). FIG. 7 shows a diagram corresponding to FIG. 2 in such a case. In this case, the brace 24c is preferably fixed at one end to one bolt 12a and at the other end to the other bolt 12b.

In the above embodiment, the horizontal member having upper and lower flanges has been described, but the present invention is not limited to this, and the lower flange may be omitted. In this case, the configuration shown in FIG. 7 is obtained by omitting the lower angle.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.
