Description

[Detailed description of the invention]

[0001]

[Industrial applications] The present invention is used in construction sites of buildings and other various buildings, and is installed to secure a space that is not affected by the weather such as rainfall, snowfall, and wind, and to improve work efficiency and work environment. The present invention relates to a clamp device that supports various types of temporary attachments that are used by being attached to a frame member of a temporary tent for construction.

2. Description of the Related Art As is well known, most of civil engineering and construction works are carried out outdoors, and are affected by natural conditions such as rainfall, snowfall and wind. The operating rate is extremely reduced, which causes delays in work processes or an increase in construction costs due to a decrease in the operating rate.
In addition, outdoor work that is susceptible to natural conditions as described above not only impairs the health of workers, but also causes slips, falls, and other physical injuries due to the deterioration of the work environment, while reducing the quality of concrete and steel frame welding. It is also a cause. On the other hand, in civil engineering construction work in urban areas, dust and noise are unavoidable due to the construction work, and it is indispensable to give consideration to surrounding areas.

In recent years, for the purpose of improving the working environment as described above, a temporary tent or a dome-type temporary roof device having a structure capable of completely surrounding the entire site or a part of a construction site has been developed, and a part thereof has been developed. Has already been put into practical use. The applicants have also made the following contents for the purpose of enabling on-site work even in the event of wind and rain and snowfall, and allowing normal construction work using heavy equipment to proceed under the roof. Proposed a temporary tent and its construction method (Japanese Patent Application No. 4-29924).

[0004] That is, a frame member of a temporary tent comprising a mountain-shaped roof member and pillar members with rollers fixed to both ends of the roof member is prepared in advance.
This frame is lifted one frame at a time on a girder attached to a scaffold, and a plurality of frames are fixed at a predetermined interval. Then, a purlin is passed between adjacent frames using an aerial work vehicle or an automatic scaffold. The present invention has proposed a temporary tent in which a frame unit of a temporary tent is assembled (shed together) by connecting the tent and a canvas is stretched on an upper surface of a roof of the frame unit, and a construction method thereof is proposed.

[0005]

[Technical problem to be solved by the present invention] Here, the present inventors attach, for example, environmental equipment such as hanging scaffolding and lighting equipment, other various auxiliary equipment and temporary attachments to the special frame member of the temporary tent. It is another object of the present invention to provide a clamp device capable of securely and reliably fixing and supporting a frame member at a predetermined position without causing any damage to the frame member.

[0006]

That is, the clamp device proposed by the present invention is mounted on a tent frame member having a square cross section having at least a pair of concave grooves which open outward at a corner portion, and various temporary attachments are mounted. A clamp device for supporting, comprising: a pair of L-shaped fixed clamp pieces formed on a top of a clamp body; and an L-shaped movable clamp piece arranged to face the fixed clamp pieces. Is provided with a tightening bolt which is screwed with these to advance and retreat the two clamp pieces so as to be able to come and go, and the leading ends of the two clamp pieces are fitted and inserted into the pair of concave grooves in the frame member. A clamp device that has a formed male ridge and a hanger to which various temporary attachments are attached integrally below the clamp body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the clamp device of the present invention will be specifically described based on embodiments. FIG. 1 is a front view of the present invention,
4 shows a state where the tent frame member is fixedly supported. FIG.
Shows details of a frame member forming the temporary tent. As shown in FIG. 1, the clamping device 21 of the present invention
It is attached to a tent frame member 11 having a square cross section and having at least a pair of concave grooves that open outward at the corners. An upper part of the clamp body 22 in the present apparatus is provided with a pair of L-shaped fixed clamp pieces 23a and an L-shaped movable clamp piece 23b arranged so as to face the clamp pieces 23a. , 23
The clamp body 22 is provided with a tightening bolt 24 which is screwed with these to advance and retreat the two clamp pieces so as to be able to come and go. At the lower part of the clamp body 22, a hanger 26 to which various temporary attachments are attached is integrally fixed.

Here, the structure of the frame member 11 will be described. This frame member 11 is fixed to a mountain shape when a tent is assembled in a hut, and is fixed to a rafter constituting a roof portion and an eave-side end of the rafter. Used as a supporting post. The frame member 11 is formed of a high-strength, lightweight structural material, and specifically, is formed of an aluminum alloy hollow elongated member having a substantially rectangular or square cross section as shown in FIG. Further, as shown in the figure, the hollow long-shaped member is formed at the upper and lower ends of the two opposing side walls 11a, 11a with outwardly open concave grooves 13, 13. This groove 1
3, the tent canvas 10 is inserted as shown in FIG. 5 so that the tent canvas 10 can be used as a slide groove for pushing and fixing the holding bead 16.

FIGS. 3 and 4 show the frame member 11.
1 shows the clamp device 21 of the present invention attached to the present invention, and the hanging scaffold 30 supported by the hanger 26. This hanger is assembled in a triangular shape as an example, as shown in FIG. 3, and a scaffold 30 with a handrail is integrally fixed to a lower part of the hanger on one side. When attaching the clamp device 21 to the frame member 11,
The fastening bolt 24 is loosened to separate the fixed clamp piece 23a and the movable clamp piece 23b, and the male ridges 25a and 25b at the tip of the clamp piece are separately inserted and fixed in the concave grooves 13 of the frame member. . Thereafter, the clamp pieces 23a and 23b are attached by tightening the fastening bolts 24 so as not to open. In addition, the code | symbol 30a in a figure has shown the scaffold board.

As described above, when the clamp device of the present invention is transported to the site and installed on the frame member, the suspension scaffold 30 can be securely and reliably fixed and supported at a predetermined position without causing any damage to the frame member. it can. This clamp device is not limited to the hanging scaffold 30, but various auxiliary equipment such as a lighting equipment 31, a fan 32, a heater 33, other environmental equipment, and a ramp 34 for extending the tent canvas 10 on a tent support. And temporary attachments can be attached, and examples thereof are shown in FIGS.

[0011]

[Effects of the Invention] As described in detail above, according to the present invention, when the clamp device is carried into the site and installed on the frame member, environmental facilities such as hanging scaffolds and lighting facilities, and various other auxiliary facilities are immediately provided. And temporary attachments can be attached and used. In addition to being able to safely and securely fix and support the temporary tent at a predetermined position without causing any damage to the special frame member of the temporary tent for construction, the device itself has a simple structure and is durable. It is extremely useful.
