Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a covering sheet that can be easily used at a civil engineering site or a construction site.

[0002]

[Prior art]

 At civil engineering sites and construction sites, synthetic resin covering sheets are often used to appropriately cover structures at work sites, etc. And connect them. FIG. 5 shows this state. Immediately after that, the covering sheets 1, 1 ', 1 ", 1'". ． ． The ropes 3 are connected by sequentially passing the ropes 3 through the string loops 2 provided at appropriate intervals around the ropes.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional product, it is troublesome to alternately pass the ropes 3 through the string loops 2 of the adjacent cover sheets, and it is very troublesome to release them. In addition, no measures have been taken to waterproof the connecting parts, which causes problems such as water leakage. The present invention is intended to solve the above problems.

[0004]

[Means for Solving the Problems]

 According to the present invention, a male member or a female member of a fastener is attached around a rectangular synthetic resin sheet, and if necessary, a wide range of necessary area can be coated continuously in the longitudinal direction and / or the lateral direction through these fasteners. Close. At this time, a pair of upper and lower stacked plates are bolted with the sheets sandwiched at the joint where the four cover sheets are joined together in a cross shape, and the upper plate and the sheet surface are in contact with each other via the packing. . Also, at the joint in the longitudinal direction where the fastener is attached, a narrow cover piece of the same synthetic resin material that covers the fastener joint from one covered sheet to the other covering sheet is provided on either side. It is configured to be attached to.

[0005]

[Action]

 The covering sheets can be joined easily by using fasteners, and the desired width can be arbitrarily obtained. On the other hand, a narrow cover piece is attached to the fastener part where the adjacent cover sheets are joined, and a waterproofing measure is applied to the place where the four cover sheets are joined together in a cross shape with a laminated plate. Therefore, rainwater will not penetrate into the interior as in the past.

[0006]

【Example】

 FIG. 1 shows the structure of the present invention, in which 1,1 ', 1 "... are synthetic resin covering sheets formed in a certain size with vinyl chloride or the like, and are made of glass fibers as appropriate. Although the above is the same as the conventional product, in the present invention, the fastener 4 made of synthetic resin is attached to the peripheral surface of the covering sheet, and the fastener 4 is attached to the male member at the time of attachment. The member 4a and the female member 4b are separately separable from each other, and are attached to the opposite sides of the covering sheets 1 and 1'which are joints.

At this time, when the overall shape of the covering sheet is a square, it does not matter whether it is a vertical side or a horizontal side, but when the covering sheet is a rectangle, the long side and the short side are distinguished from each other, and the male member 4a or Allow the female member 4b to be attached. Reference numeral 5 denotes an operation ring, which is attached to one side covering sheet (1 in the illustrated example), and when joining, inserts the facing male member 4a or female member 4b into the sliding member 5a of the operation ring 5, and The other end is fixed to the stopper 5b.

Reference numeral 6 is a strip-shaped fin piece of the same synthetic resin material that is attached to one side of the above-mentioned joint portion of the cover sheet, and has a width dimension that enables the upper surface of the fastener to be covered toward the adjacent cover sheet. s. The strip-shaped fin pieces 6 are arranged alternately on the four outer edges of the covering sheet, and the edge direction of the strip-shaped fin pieces 6 may be changed between the adjacent covering sheets at the time of joining. It is also possible to attach one cover sheet to the entire periphery and to create two types of cover sheets that are not attached at all.

FIG. 2 shows the covering sheets 1, 1 ′. ． ． This shows the state in which four of the above are connected by the fastener 4, and it can be performed by a simple operation, while the upper surface of the fastener is covered with a strip-shaped fin piece 6 to protect the waterproof of the upper surface of the joint and the protection of the fastener. To be obtained.

FIG. 3 shows a waterproofing measure to be applied to a joint where four cover sheets are joined together in a cross shape when the cover sheets are joined. 7a and 7b are a pair of upper and lower laminated plates. is there. The lower plate 7a of the stacking plate has a bolt screw 8 of a certain height standing upright in the center thereof, and 9 is a nut screwed with the screw 8. On the other hand, the stop plate 7b is bowl-shaped, and has a hole 10 at the center thereof, into which the bolt screw 8 is inserted. In the drawings, 11 and 12 are ring-shaped packings, which are used at the time of mounting as described below.

FIG. 4 is a view showing the above-mentioned mounting state, in which the adjacent cover sheets 1 and 1 ′ are connected by a fastener 4 and a lower plate is provided at a position where the four cover sheets are combined in a cross shape. 7a is placed, the bolt screw 8 of the lower plate 7a is projected upward from the cross-shaped notch, and the upper plate 7b is inserted through the through hole 10 with the curved surface of the upper plate 7b facing downward. After that, the nut 9 is screwed and fixed. At this time, packing 11 and 12 are interposed between the place where the upper plate 7b comes into contact with the covered sheet surface and the nut 9 comes into contact with the upper plate 7b.

The present invention is configured as described above, and metal plates may be used for the laminated plates 7a and 7b, but it is preferable to use a synthetic resin because it is lightweight and excellent in rust prevention effect. It should be noted that the strip-shaped fin pieces 6 in the cylinder closed with the fasteners 4 should be provided with the surface fasteners 13 (using a double-sided tape or the like) at an appropriate pitch between the strip-shaped fin pieces 6 and the covering sheet. I can.

[0013]

EFFECT OF THE INVENTION The present invention is configured as described above, and when joining, the covering sheets 1, 1 ', 1 "... Therefore, the workability is very good. On the other hand, it can be easily done by the reverse operation at the time of detachment. Since waterproof measures are taken by using the laminated plates 7a and 7b, it is possible to completely prevent the ingress of rainwater toward the inside. It is possible to effectively prevent the loss of sediment due to wind and rain immediately after construction.
