Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a tarpaulin device, and more particularly to a tarpaulin device in which the covering portion of the sheet can be opened and closed, and is suitable for rainproofing large equipment or objects.

[Background of the idea] Conventionally, objects are covered with waterproof sheets to protect them from rain. For example, when covering large mechanical equipment, large objects, large amounts of packaging, etc. with sheets, it is necessary to build a solid framework and cover the objects with a tarpaulin sheet. The work is time consuming as it requires a tarpaulin sheet to secure it in place. For example, when installing a large condenser for thermal power generation outdoors, you must first erect pillars and beams to house the entire condenser and then cover them with a large waterproof sheet, which requires a lot of man-hours. The tarpaulin sheet may be temporarily opened due to installation work, but it is not easy to open and close the sheet once it is in place. Therefore, there has been a need for an assembly-type waterproof sheet device that can completely protect objects from rain and that can easily open and close the covering portion of the sheet.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the drawbacks of the prior art and provide a tarpaulin device that can be easily assembled and can freely open and close the covered area of the tarpaulin.

[Summary of the idea]

The waterproof sheet device of the present invention is suitable for equipment that is to be waterproofed,
A suitable number of movable gate-shaped brackets are arranged side by side on rails laid around the object, and a flexible waterproof sheet is covered over the beams of each of the gate-shaped brackets to form a roof. This device has a structure in which the flexible sheet is folded by moving a bracket on the rail.

By connecting the gate-shaped brackets arranged side by side on the rail with a tension cable, the portal brackets can be moved by remote control by pulling the tension cable back and forth. Further, by attaching a presser bar between the beams of each of the gate-shaped brackets on the roof of the flexible waterproof sheet, it is possible to prevent the sheet from swaying in the wind. In addition, if the flexible waterproof sheet is too wide, in order to reduce the load on the portal bracket, divide the sheet roof into two or more parts in the rail direction, and insert along the border of the divided roof. Hanging the flexible waterproof sheet from the end of the portal bracket to an appropriate length,
Another flexible waterproof sheet is added inside this hanging sheet to form a sheet side wall, and the slope of each divided roof is raised by raising the end of the beam of the portal bracket on the boundary side. By forming a chevron-shaped roof with a raised center part of the beams and installing rain gutters under the rails along the boundaries between each roof division, a structure with good water flow can be achieved.

As mentioned above, the feature of the present invention is that it is an assembly type waterproof sheet device in which a roof is formed by covering a movable gate-shaped bracket with a flexible waterproof sheet, and the covered area can be opened and closed by folding the sheet neatly. .

[Example of idea]

An example of the waterproof sheet device of the present invention will be explained with reference to FIGS. 1 to 3. 1 is a perspective view of the entire waterproof sheet device, FIG. 2 is a lateral sectional view of a portion of the device, and FIG. 3 is a longitudinal sectional view thereof. Regarding Fig. 1, four rails 2 are laid in parallel on the object (not shown) to be rainproofed, two adjacent rails 2 are set as one set, and an appropriate number of gate-shaped rails are placed on top of the set. Place brackets 1 side by side. The gate-shaped bracket 1 consists of an upper beam and both legs, and a wheel 7 is attached to the lower end of the leg, and the outside of the wheel 7 is covered with a plate-like cover 10. The gate type bracket 1 is placed across the set of rails 2, and the gate type bracket 1 can be moved back and forth on the rails 2. A flexible waterproof sheet 3 is placed over the beams of each gate-shaped bracket 1 to form a roof, and the sheet 3 is hung down to an appropriate length from the end of the beam to sufficiently prevent rain from entering the sheet. With this structure, the flexible waterproof sheet 3 for moving the portal bracket 1 on the rail 2 is folded between the beams, and the covered area can be freely opened and closed. In addition, a presser bar, for example, a round bar 5, is attached to the middle of each gate-shaped bracket 1 on the roof of the flexible waterproof sheet 3 to prevent the flexible waterproof sheet 3 from flapping around in the wind. Make it. Further, as shown in FIG. 3, a pulley 8 is provided at the end of the rail 2, and the legs of each gate-shaped bracket 1 lined up on the rail 2 are connected with a tension cable 6, such as a rope or wire, and the rope 6 is By pulling back and forth in the rail direction through the pulley 8, the portal bracket 1 can be moved by remote control to open and close the seat.

When the covering surface is wide, the sheet area is large and heavy, and from the viewpoint of strength resistance and smooth movability of the portal bracket member, it is preferable to divide the flexible waterproof sheet into two or more parts in the rail direction. FIG. 1 shows a case where the flexible waterproof sheet is divided into two parts at the center. In order to prevent rain from coming from the dividing line of the sheet, as shown in Fig. 2, a flexible waterproof sheet 3 is hung from the end of the beam of the gate-shaped bracket 1 to an appropriate length, and the inner side of this hanging sheet is Another flexible waterproof sheet 9 is added to form a sheet side wall 9, and a rain gutter 4 is provided under the rail 2 along the boundary. Further, the slope of the roof of the sheet is made higher at the end of the beam of the gate-shaped bracket 1 near the boundary to form a single-roof type. With this structure, rain flows to the outside of the sheet, and rain that falls at the border is blocked by the hanging portions of the sheet and the side walls 9 and flows into the rain gutter 4. In addition, by increasing the number of rails and gate brackets, the seat can be divided into 3 parts.
When dividing the sheet into sections or sections, if both sides of the sheet are the dividing line, the central part of the beam of the gate-shaped bracket is raised to create a chevron-shaped roof with a slope, allowing rain to flow to both sides. By dividing the roof in this way, the weight of each portion of the flexible waterproof sheet can be reduced, the load on the portal bracket can be reduced, and the structural members can be light and easily moved.

The gate-shaped bracket has a structure in which the legs and beams are tightened and fixed using U-bolts or the like, so that assembly, disassembly, and transportation and storage of components are facilitated. In addition, in order to adjust the distance between the gate-shaped brackets arranged side by side to an appropriate length, it is recommended to stretch a chain between the legs of each gate-shaped bracket so that the distance between the legs does not become too large. If the chain is not tensioned, the sheet tension is used to move the portal bracket, which reduces the service life of the sheet and makes the movement less smooth. Furthermore, by making the width of the cover 10 of the wheel 7 of the portal bracket larger than the width of the leg portion, when the portal bracket is brought close to each other, a gap is created between the leg portions, which is preferable as it becomes an allowance for folding the seat.

Next, an example of using the waterproof sheet device of the present invention for rainproofing a large condenser will be described with reference to FIG. The condenser 11 is a large piece of equipment that is difficult to assemble inside a building, so it is assembled outdoors. First, the outer frame of the condenser 11 is assembled, the rails 2 are laid using this outer frame, and the gate-shaped bracket 1 is placed on it. Because the sheet covers a wide area, two flexible waterproof sheets are placed in the center.
It is divided into sections and placed over the portal bracket 1, and the legs of each portal bracket are connected with a rope 6. 4th a
The figure shows a fully covered state in which the flexible waterproof sheet is stretched over the condenser 11 in both directions A and A', and Figure 4b shows the sheet stretched in the B' direction by pulling the rope 6 in the direction of arrow B. FIG. 4c shows the state in which the folded covering area is opened, and the state in which the rope 6 is pulled in the direction of arrow C, the sheet 3 is expanded in the direction C', and the covered area is closed. In this operation, the opening and closing of the sheet 3 can be easily and remotely controlled by pulling the portal bracket 1 from the front and back with the rope 6, so that the covering of the sheet 3 can be made very easily.

After forming the roof of the sheet 3, the internal components of the condenser 11 are attached, and after that, the waterproof sheet device is removed, and the condenser 11 is drawn into the building and installed at a predetermined position. The waterproof sheet device of the present invention can be easily assembled on-site even for huge equipment such as a condenser, and it is also easy to disassemble and transport parts.
Furthermore, the sheet covering area can be opened and closed to an appropriate size depending on the construction situation, making it a truly suitable device.
