Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete form supporting apparatus (not used) for forming walls, pillars, bases, etc. with concrete. In particular, it is suitable for a metal concrete formwork that can be used repeatedly, is easy to attach and detach, and can be used repeatedly. 2. Description of the Related Art A concrete form supporting apparatus is provided to support a concrete form which is opposed to form a wall or the like from the outside so as to prevent hardened concrete from falling down and to make the finished concrete wall vertical. It is to be.
Conventionally, in general, a concrete formwork supporting device is composed of an extremely large number of components such as a horizontal fluttering material, a vertical fluttering material, a column, a brace, a metal fitting for connecting these members, and the like. [0003] In such a conventional supporting device, the number of parts is extremely large, and management, carrying-in to the site, assembling, mounting and fixing, and removal after curing and curing of concrete are extremely troublesome. Work had been done. SUMMARY OF THE INVENTION The present invention has been developed in view of the above-mentioned conventional troublesome work, and its gist is to provide a metal concrete formwork having vertical and horizontal ribs. The support device, consisting of a horizontal leg connecting one end to the lower part of the concrete form, and a pillar that is inclined and connected to a seat plate that connects one end to the upper part of the concrete form and the other end to the floor surface, The other end of the horizontal leg is connected to the lower portion of the support, and the support can be adjusted with a turnbuckle interposed therebetween. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing a use state of a concrete formwork supporting device according to the present invention, and FIG. 2 is an exploded perspective view of the supporting device. The concrete form 1 is made of metal, that is, a face plate 11 made of a steel plate or an aluminum plate, and vertical ribs 12 and horizontal ribs 1 around the back surface.
3. It has auxiliary ribs 14 parallel to the horizontal ribs 13 and middle ribs 15 parallel to the vertical ribs 12. These various ribs can be made of the same material as the face plate 11 or plywood. The illustrated example is made of a metal plate, and the auxiliary ribs 14 and the middle ribs 15 are made of grooved plates. The vertical ribs 12 and the horizontal ribs 13 are connected through up and down
a, 13a have the number of enemies. In addition, through-holes 14a penetrating to the face plate 11 are arranged in the upper, middle, and lower portions of the auxiliary rib 14, so that a tie rod of a spacer (not shown) can be penetrated. [0006] The concrete form 1 is vertically supported from the back by one supporting device 2 with respect to the concrete form 1. In this embodiment, the horizontal legs 3 are arranged near the floor. And a support 4 that is passed diagonally and fixed to the horizontal leg 3. The support 4 is connected to a seat plate 5 that is fixed to the floor surface, and the support 4 can be adjusted with a turnbuckle 43 interposed. It was made. The horizontal leg 3 is formed by connecting a pair of rectangular plates 32 to a channel plate 31 by bolts 33 and nuts (not shown). A hole 34 is formed in one end of the channel plate 31.
One end is inserted into the auxiliary rib 14 below the concrete form 1 and overlapped with the hole formed in the auxiliary rib, and is removed by a pin 35 having a grooved hole at the tip and a cotter 36 which is driven into the grooved hole. The lower end of the column 4 is inserted between the joints 32 at the other end, and the other end is connected with a set screw 37 and a nut (not shown). The column 4 is configured such that round rods 41 and 42 with bolts are screwed into a turnbuckle 43 and a clamp 44 is provided on the round rod 41 with bolts on the upper part. 43
“a” is an operation hole formed in the body of the turnbuckle 43. The clamp 44 has a U-shaped main body 44a that enters the auxiliary rib 14 and a mounting piece 44b sandwiching the upper end of the round bar 41 with bolts, and the mounting piece 44b and the round bar 4 with bolt.
The bolts 45 and nuts 46 through which the nuts 1 pass are integrated. Holes 44c, 44c are drilled on the upper and lower sides of the main body 44a of the clamp 44, overlapped with a hole (not shown) provided in the auxiliary rib 14, and detachably connected by a pin 47 and a cotter 48 having a grooved hole at the tip. is there. The round bar 42 with bolts at the lower part of the column 4 is connected to the horizontal leg 3 by the set screw 37 and the nut as described above. At the lower end of the support 4, that is, at the open end of the bolted round bar 42, a pair of upright plates 51 provided with a steel plate 5,
51, and are connected by bolts 51a and nuts (not shown). The seat plate 5 has a suitable number of mounting holes 52 around it.
And is fixed to the floor surface with the anchor bolts 6 from the mounting holes 52. Therefore, the support column 4 is arranged to be inclined between the auxiliary rib 14 of the concrete form 1 and the seat plate 5. The support device 2 having such a configuration is used to form a partition wall of a concrete building, for example, by surrounding concrete bars with concrete forms 1 and 1 and facing each other, and reducing the thickness of the wall surface by a spacer (not shown). The concrete forms 1 are arranged at corresponding intervals, and the concrete form 1 is used after being connected in a plurality of lateral directions to the length of the partition wall. At this time, a seat plate 5 made of a steel plate is arranged on the floor surface in advance and fixed with anchor bolts 6. The horizontal leg 3 and the support 4 of the support device 2 are spread, and are put into the auxiliary ribs 14 on the upper part of the concrete form 1 by the clamps 44 on the support 4, passed through the pins 47, and driven into the cotter 48 to be fixed. Similarly, one end of the horizontal leg 3 is inserted into the auxiliary rib 14 and fixed with the pin 35 and the cotter 36. Thereafter, the lower end of the column 4 is placed between the upright plates 51, 51 of the seat plate 5, the bolt 51a is passed through the column 4, and a nut (not shown) is tightened and fixed. Note that the lower end of the column is fastened to the seat plate 5 by tightening it with bolts 51a and nuts (not shown) in advance. The seat plate 5 may be fixed to the floor. In order to make the concrete form 1 vertical by the support device 2, the length of the column 4 is changed by extending or reducing the length of the column 4 by inserting a tool into an operation hole 43 a formed in the side surface of the turnbuckle 43 and rotating it. So that the concrete formwork 1 is exactly vertical. The pins 35, 47, and the cotters 36, 48 are used to easily attach and detach the horizontal legs 3 and the columns 4 of the support device 2 to and from the concrete form 1, but bolts and nuts are used instead. Can also be used. Further, the attachment portions of the horizontal legs 3 and the support columns 4 to the auxiliary ribs 14 are formed in a plane arc shape, so that the concrete form 1 is removed after the concrete wall is hardened. 2 with pins 35 and 47
Can be rotated about the fulcrum to be along the concrete form 1 to reduce the bulk so as to be ready for the next use. According to the present invention, the supporting device is composed of a horizontal leg and a supporting column which is connected at an angle. The supporting device is carried to the site and then connected to the back of the concrete form. Fine adjustments are made with a turnbuckle on the way, and the concrete formwork is set up vertically by a simple operation. And the structure is simple and can be used repeatedly. [0013]
