Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork device used in underwater concrete construction for breakwaters and the like.

Conventionally, in the underwater concrete construction method for breakwaters, etc., a rectangular formwork with formwork panels integrated with support members is assembled on land, then suspended by a crane and submerged in water, and then the concrete is placed inside the formwork. This is what is being poured. However, because of the U panel, it is susceptible to the effects of waves, making it difficult to sink and install the formwork in a fixed position on the seabed, and the formwork as a whole is easily damaged by waves.

In order to solve the above-mentioned drawbacks, the present invention has developed a mold in which formwork panels are inserted between the respective supports of a support frame material in which formwork supports are arranged in a rectangular shape, and are removably locked with bolts. The frame device is designed so that the support frame material and formwork panel can be separated, so that during construction, the support members are first set down and then the formwork panels are attached, minimizing the effects of waves. The structure is characterized by the fact that the strut members can be easily assembled on land, there is little danger in the work, and it is possible to save labor during construction.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

Left and right corner supports 2, 2' with vertical grooves 1, 1 on two sides, one side and the back, are formed to an appropriate height, and connecting members and formwork holes are installed on the front and left side of the left corner support 2. Bolt holes for locking with the flannel are provided in multiple stages, and bolt holes for locking the formwork panel are provided in multiple stages at positions near both sides of the front of the intermediate support 3, which has vertical grooves 1, 1 on both sides, and the bolt holes for locking the formwork panel are provided in multiple stages. Bolt holes for spacing material retainers are provided in multiple stages at line positions, and the left corner support 2 and right corner support 2' are erected at appropriate intervals on the left and right, and an arbitrary number of bolt holes are provided at the intervals between the left and right corner supports 2, 2'. The front intermediate struts 3 are erected at specified intervals, and the front connecting members 4, which are H-shaped in end view, are placed in front of the left and right corner struts 2.2' and the front intermediate struts 3 at appropriate intervals vertically. The vertical grooves 1, 1 are placed in the rear direction of the left and right corner columns 2, 2/, and are removably fastened to each column with bolts 5.
An arbitrary number of left and right side intermediate struts 3/, 3/ are erected at prescribed intervals, with the front and rear directions extending in the front and rear direction, and each left and right side intermediate strut 3'.

3' and the left and right connecting members 4 on the outer surfaces of the left and right corner supports 2, 2'.
/, 4/ are spaced vertically at appropriate intervals, and both ends of the front connecting member 4 and the ends of the left and right connecting members 4/, 4/ cross vertically, and are removably tightened with bolts 5'. The plates 6 and 6' on the upper and lower surfaces of the intersection between the front connecting member 4 and the left and right connecting members 4' are connected with bolts 7, and spacer retaining materials are installed on the opposing inner surfaces of the left and right side intermediate columns 3/, a/ that are left and right opposite. 8 are arranged in several stages above and below, and the plates 9 at both ends of the spacing member 8 are removably connected with bolts 10, and between the upper and lower members of the front connecting member 4 and the left and right connecting members 4/, 4/, respectively. The support frame 13 is assembled by removably extending the stays 11 in a crosswise manner to the bins 12 protruding from each member, and the left and right corner supports 2.2' are attached to the front and both sides of the support frame 13. Projections 1 at both ends of the formwork panel 14 are placed in the longitudinal grooves 1, 1 on the mutually opposing surfaces of the front intermediate column 3 and the left and right side intermediate columns 3', 3'.
.

5.15, fit and insert any number of formwork panels 14, and connect the protrusions 15° 15 at both ends of each formwork panel 14 to the left and right corner supports 2.2' and each intermediate support 3.3'. It is designed to be pressed and locked using a locking bolt 16 that is screwed into the locking bolt 16. In addition, 17 in the figure shows a concrete body.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The formwork device according to the present invention is used for underwater concrete construction, in which the support frame material 13 is first assembled on land, etc., and after the support frame material 13 is deposited in a predetermined position in seawater, each support is assembled. Projections 15, 1'5 at both ends of the formwork panel 14 are inserted into the opposing vertical grooves 1, 1 and are pressed and locked with locking bolts 16.

The strut frame material 13 has left and right corner struts 2', 2', front intermediate struts 3, and left and right side intermediate struts a/, 3/ arranged at prescribed intervals to form an arbitrary number of front connecting members 4 and left and right connecting members. 4′,
At the same time, spacing members 8 are connected at an arbitrary number of stages at 4 degrees on the opposing surfaces of the left and right side intermediate struts a/ and 3/, and stitches 11 are stretched between the upper and lower stages of each connecting member 4.4'. It is set up,
Since the projectile does not cause strain or the like and is lightweight, it is easy to submerge it in seawater, and since no formwork panel 14 is attached, there is less influence from waves and the work can be made more efficient. The protrusions 15 of the formwork panel 14 fitted into the vertical grooves 1, 1 of each support are pressed by the locking bolts 16 of each support to bring the protrusions 15 into close contact with the inner surface of the groove on the opposite side, thereby preventing concrete from flowing out. After the concrete has solidified, remove the bolts 10 of each spacing member 8, loosen each locking bolt 16, and remove the formwork panel 14 from within the support frame material 13. 13 clay/
etc., and can be easily moved to the next pouring position, and workability in concrete pouring work is improved by constructing the support frame material 13 and the formwork flannel 14 so that they can be separated. It has the remarkable effects mentioned above, such as improved performance and labor saving.
