Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved formwork for supporting cast concrete.

[0002]

2. Description of the Related Art Conventionally, regarding a formwork having a curved surface for supporting concrete cast at the time of molding of the structure, a formwork that matches the curved surface which is the outer surface of the structure is manufactured, and a veneer plate is attached to this. It was pasted and manufactured.

[0003]

However, in such a conventional one, it is difficult to manufacture because a mold bone matching the curved surface of the body must be manufactured each time.
It is expensive because of the large number of parts.

Further, when it is actually installed in the body molding site, when the fit is poor, it is necessary to realign the parts, which is difficult to correct.

When a curved frame is manufactured in a factory, the number of parts is large and the transportation cost is high.

Therefore, even if an attempt is made to reduce the cost by performing on-site production, there is no craftsman to produce it.

Further, even if an attempt is made to divert from one site to the next, the curved surfaces at the molding sites of each skeleton are different. Can not be dealt with, so it becomes a waste material, and there is a problem of waste treatment.

[0008] Therefore, the present invention is to provide a standardized curved form frame which can be easily formed into a shape having an arbitrary curvature and can be repeatedly diverted.

It is another object of the present invention to provide a curved frame which can be easily installed or removed at a building molding site by anyone who can understand architectural drawings.

[0010]

In order to achieve the above object, the structure of the present invention is such that a plurality of reinforcing beams are coupled to the back surface of a frame panel and holes are formed at equal intervals in each reinforcing beam. , A thick end member is erected via a swingable mounting member between arbitrary reinforcing beams, a tightening metal fitting is attached to this thick end member, a bracket is provided on each reinforcing beam, and a turnbuckle is provided between each bracket. The present invention is characterized in that the bracket is formed in a T shape having a socket and a supporting portion, the end portion of the turnbuckle is fixed to the socket, and the supporting portion is fixed to the reinforcing beam.

[0011]

According to such means, when the turnbuckle is rotated in one direction, each turnbuckle is compressed, each reinforcing beam is pulled by the turnbuckle, and it is possible to force the curved panel to have a desired curvature. I can.

Further, when a plurality of curved frame members are continuously arranged in the width direction, the holes of the reinforcing beams can be utilized to sequentially connect them with bolts.

Further, it is possible to sequentially connect in the height direction by using a connecting member.

Since it is possible to integrally connect the supporting work through other horizontal members and diagonal members connected to the holes of the respective reinforcing beams, anyone can easily install it on the construction site.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 6 show an embodiment of the present invention.

For this reason, when the turnbuckles 21 and 21 are in the neutral position, the form panel 11 is horizontal, and when they are rotated in one direction to shorten, that is, when they are rotated in the compression and tension directions, the reinforcing beams 12 and The present invention can be applied to support a building or a structure in which 12 and 13 are stretched, the frame panel 11 is curved, the outer surface is curved, or an arch is formed.

The reinforcing beams 12 are arranged at equal intervals, for example, 30.
It has holes at 0 mm intervals.

The holes at the upper end and the lower end are also used for fixing the connecting member 50 and the lower adjusting jack when connecting the curved frame in the vertical direction.

As shown in FIG. 3, the thick end member 30 is formed by joining two frame bodies 31 and 11 having a U-shaped cross section back to back with an arbitrary gap provided, and the mounting member 32 is a frame body. 31 is swingably connected.

The attachment member 32 is T-shaped in a plane and swings when the frame panel 11 is curved so that the supporting surface follows the curved surface.

As shown in FIG. 2, the bracket 23 includes a hollow horizontal socket 23a and a support portion 2 in the depth direction.
3b and a T-shaped pipe,
b is fixed to the reinforcing beams 12 and 13 by a bolt or the like through a hole, and the end portion of the turnbuckle 21 is fixed to the socket 23a through a pin 22.

The turnbuckle 21 is composed of a threaded cylinder and a threaded rod movably inserted into the threaded cylinder as is well known.

The reinforcing beam 12 and the frame panel 11 can be connected in the vertical direction, and they are connected to each other via a connecting member 50.

As shown in FIG. 4, the connecting member 50 includes a support rod 51 that contacts the back of the reinforcing beam 12 and a support rod 51.
A fork-shaped bracket 52, a screw rod 54 inserted into a groove 53 in the back of the bracket 52, and a nut 55 screwed into the screw rod 54. Two upper and lower brackets 52, 52 respectively inclined in opposite directions are fixed to the 12 by bolts, and in this state, the upper and lower nuts 55, 55 are tightened to connect the upper and lower beams 12, 12.

FIG. 6 shows an apparatus for connecting the curved frame of the present invention to a support pole.

That is, as shown in FIG. 6, the bracket 60
A flange 61 is coupled to the flange 61, and another scaffolding frame or a supporting pillar 6 is attached to the flange 61 via a horizontal member 62, a diagonal member, or the like.
It is connected to 7 and used as a stand for the self-supporting formwork device during assembly and as a support during concrete pouring.

The flange 61 is provided with a semi-circular or fan-shaped horizontal main body 63, a hooking piece 64 standing upright on the outer periphery of the main body, and a pillar body 65 standing upright in the center of the main body 63.

The horizontal member 62 is a pipe and a hook provided on the tip of the pipe 62 and hooked on the flange 61,
And an engaging portion 66 including a claw and a shoe.

As shown in FIG. 5, the lower adjustment jack 70
Is composed of a bracket 71 and a screw jack 72, and is connected to the hole 73 provided in the bracket and the hole at the lowermost end of the reinforcing beam 12 by a bolt and used for adjusting the height of the frame panel.

[0031]

The present invention has the following effects.

1) A circular, arched, or corrugated concrete supporting surface that matches the curvature of the outer surface of a building or the outer surface of a body to be molded can be freely and easily manufactured by operating a turnbuckle.

2) Since the curvature can be freely changed,
One standardized curved frame can be diverted from one site to the next, so there is no need to dispose of it and it is economical.

3) The number of turnbuckles can be increased or decreased by utilizing the holes of the reinforcing beam depending on the thickness of the frame frame panel.

4) A person who can understand the architectural drawings can install the curved frames according to the size by using the holes of the reinforcing beam to sequentially connect a plurality of curved frame frames in the width and height directions.
You can easily adjust the fit when installed on site by operating the turnbuckle.

4) Since the single standard curved frame is constructed, it is suitable for storage and transportation, and the transportation cost can be reduced.

5) Since anyone can use the hole of the reinforcing beam and can integrally connect it with the supporting work and the frame scaffolding, anyone can easily install it.
