Abstract

(57) [Summary] [Purpose] Positioning and mounting can be done by simple work. [Structure] One side mounting portion 2 in the width direction, a curved portion 3 in the middle in the width direction, and another side mounting portion 4 on the other side in the width direction. 8 is connected, and the linear object 8 is tied to the reinforcing bar of the formwork so that it can be temporarily fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water stop plate used for watertight expansion and contraction joints of concrete structures.

[0002]

[Prior Art]

 When a concrete structure undergoes a change in temperature or moisture or a drying shrinkage, if it can expand and contract freely, no internal stress will be generated, but if the deformation is limited, it may crack, so that the concrete structure can be cracked. Watertight expansion and contraction seams are provided at appropriate positions on the structure to prevent cracking. This watertight expansion / contraction seam is also effective in preventing cracks due to uneven settlement of the foundation, load and vibration.

[0003]

[Problems to be solved by the device]

 As a watertight expansion / contraction seam of such a concrete structure, it is known that a water stop plate is attached across adjacent concrete structures, but the work of attaching the water stop plate to the concrete structure is very troublesome. Becomes For example, in the case of a cast-in-place type concrete structure, a formwork is assembled to the foundation, a water stop plate is temporarily fixed between the adjacent formworks, and in that state, concrete is driven into the formwork to adjoin. Water blocking plates are installed across concrete structures, but since the water blocking plates are plate-shaped, it is very troublesome to position and temporarily fix them across the formwork.

Therefore, an object of the present invention is to provide a water blocking plate that can solve the above-mentioned problems.

[Means for Solving the Problems]

 A water blocking plate with linear objects connected to the mounting parts on one side and the other side on both sides in the width direction.

[Operation] The water blocking plate can be temporarily fixed by connecting the linear object to the reinforcing bar of the formwork, and the connection of the linear object can be adjusted and positioned.

【Example】

 As shown in FIG. 1, FIG. 2 and FIG. 3, the water stop plate 1 is a long plate shape having a predetermined width and thickness, and the one side mounting portion 2 in the width direction and the curved portion in the width direction middle portion are curved. It is composed of the portion 3 and the other side mounting portion 4 on the other side in the width direction, and a thin protective film 5 is integrally provided at the opening edge of the curved portion 3 so that concrete does not flow into the curved portion 3. The water stop plate 1 is made of natural rubber, synthetic rubber, synthetic resin or the like. The ridges 6 are integrally provided on the upper and lower surfaces of the one-side mounting portion 2 and the other-side mounting portion 4 in the longitudinal direction, and the widthwise edges are slightly thicker. A plurality of holes 7 are formed in the lengthwise direction along the longitudinal direction. A linear object 8 such as a steel linear object is inserted and connected to the holes 7 of the one-side mounting portion 2 and the other-side mounting portion 4.

Next, the work of attaching the water stop plate 1 will be described. As shown in FIG. 4, the formwork 11 is assembled adjacently on the foundation 10, and the vertical and horizontal reinforcing bars 12 are arranged on the formwork 11. 4 is inserted into the mold 11 through the opening 13 of the mold 11 and the linear object 8 is tied to the reinforcing bar 12 to position the water blocking plate 1 between the adjacent molds 11 and 11 and temporarily position it. Fix it. At this time, the water blocking plate 1 can be moved leftward and rightward and temporarily fixed by adjusting the connection of the linear object 8 to the reinforcing reinforcing bar 12, so that the positioning work of the water blocking plate 1 becomes easy. After that, concrete is poured into the formwork 11 to remove the formwork 11 to form a concrete structure. Adjacent concrete structures are attached to one end 2 of the water stop plate 1 and the other end of the mounting part 4 in the width direction. The part close to the edge is buried and the water stop plate 1 is attached across the adjacent concrete structures.

[0007]

[Effect of the device]

 The water blocking plate 1 can be temporarily fixed by connecting the linear objects 8 on both sides to the reinforcing reinforcing bar 12 in the adjacent formwork 11 for the concrete structure, and the water blocking plate can be adjusted by adjusting the connection of the linear objects 8. Since 1 can be moved and positioned in the direction of the adjacent form 11, it is possible to position and attach the water blocking plate by a simple operation across adjacent concrete structures.
