Description

Clamps for fastening horizontal members for system brackets {CLAMP FOR SCAFFOLD PIPES}

The present invention relates to a clamp for fastening a horizontal member for a system pole, and in particular, in order to fasten a horizontal member to a vertical supporter or to fasten a plurality of horizontal members to be disposed at a right angle to a vertical supporter, the horizontal members are simply fastened to the vertical supporter with a simplified structure It relates to a clamp for fastening a horizontal member of an improved structure to do so.

In recent construction sites, in order to install a formwork and stably support the load, the use of a system copper bar that is easy to assemble, install, and disassemble is easy to assemble and disassemble safely, and the use of a system copper bar is increasing in order to support the load stably.

This system support supports the joist that supports the shuttering from the lower side, and the yoke, which is a member installed at right angles to the joist in order to transmit the upper load to the beam, is provided at the top of the support A yoke called "U-head jack" It refers to a temporary structure that is placed on a support to support the formwork.

To the supports of the system dongbari, for example, horizontal pipes installed horizontally are connected to provide a lateral support force.

In addition, these clamps are widely used to combine horizontal members with respect to vertical supporters in scaffolding installation, and in particular, at corner portions of scaffolds, horizontal members for vertical supporters are used to couple at right angles to each other.

As an example of a clamp for connecting a horizontal member to such a support, Korean Patent Publication No. 10-1383355 (registration date April 02, 2014) discloses that the clamp for the horizontal reinforcement for the formwork is installed at right angles to each other on both sides. It consists of a support member, a cover member having one end rotatably installed on one end of the support member, and a fastening member for closely fastening the other end of the cover member and the other end of the support member. In the clamp for horizontal reinforcement for a formwork that is fixed and installed in a horizontal direction, the fastening member is rotatably installed at the other end of the support member and a pin insertion hole is drilled at the other end, the other end of the support member and the other end of the cover member a fastening rod passing through the other end of the cover member when it is in close contact; and a fastening pin inserted into the pin insertion hole of the fastening rod in a state where the other end of the support member and the other end of the cover member are in close contact with each other to fix the state in which the cover member is in close contact with the support member. are doing

As such, the structure in which the support members are installed to be perpendicular to each other has already been disclosed in Korean Utility Model Publication No. 1998-015736 (published on June 25, 1998).

However, the structure in which the two support members of the prior art are orthogonal to each other is complicated by a structure in which two clamps are orthogonally coupled to each other, resulting in an increase in manufacturing cost, and a problem in that work efficiency is lowered due to a long time for fixing the horizontal member. there was

Korea Public Utility Model Publication No. 1998-015736 (published on June 25, 1998) Korean Patent Publication No. 10-1383355 (Registration Date: April 02, 2014)

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the present invention.

In Figures 1 and 2, the clamp for fastening the horizontal member for the system of the present invention includes a first clamp member (1) and a second clamp member (2) having the same shape, and the first and second clamp members (1) Each of , 2) has a shape divided into two parts to form a tubular body having a through hole 3 in close contact with the outer surface of the horizontal member when coupled to each other, and one end is rotatably connected with a hinge pin 4 And, the other end is configured to be decomposably coupled with the fastening bolt (5).

As shown in FIGS. 3 and 4 , the fastening bolts 5 protrude apart from the other end of the first clamp member 1 , and horizontally from the lower end of the fastening bolts 5 to the supporting parts 11 in which holes are formed. The formed pin portion 51 is fitted so that the fastening bolt 5 is rotatable. In addition, in response to this, two spaced apart protruding protrusions 21 are formed at the other end of the second clamping member 2, so that the fastening bolt 5 of the first clamping member 1 is rotated to rotate the second The horizontal member is simply clamped by placing it between the protrusions 21 of the clamping member 2 and then fastening it with the nut 52 to the end of the fastening bolts disposed between the protrusions 21 .

In addition, on the outer surface of each of the first and second clamp members 1 and 2, horizontal support parts 6 are formed that are disposed at right angles to each other and extend outward in the radial direction, and each of the horizontal support parts 6 has A fixing hole 61 for fixing the end of the horizontal member with a wedge is formed.

The operation of coupling the horizontal member to the vertical supporter made of a pipe using the clamp for fastening the horizontal member for the system according to the present invention of this structure will be described with reference to FIGS. 3 to 5 .

Fasten the clamp of the present invention to the position where the horizontal member 8 such as a pipe is to be installed on the vertical supporter 7 . To this end, loosen the fastening bolts 5 and the nuts 52 from the ends of the first and second clamping members 1 and 2 of the clamp of the present invention and place them on the outer surface of the vertical supporter 7 in an open state as shown in FIG. 3 . By disposing the first and second clamping members 1 and 2, rotating the fastening bolt 5 of the first clamping member 1 and fastening it to the end of the second clamping member 2, the vertical supporter as shown in FIG. At (7), the clamp is easily mounted.

Then, as shown in FIG. 5, the horizontal support part 6 formed on the side surface of the first or second clamping member 1, 2 is fastened to the end of the horizontal member 8 in a "C" shape when viewed from above. By inserting the end 81 and passing the wedge 9 through the vertical through-hole 82 formed in the fastening end 81 and the fixing hole 61 of the horizontal support 6, the horizontal member 8 becomes the vertical supporter ( 7) is fixed against.

In the embodiment shown in FIGS. 1 to 6 , the horizontal support parts 6 formed on the outer surfaces of each of the first and second clamp members 1 and 2 extend downward in a state formed at a position spaced apart from the upper end to the lower side. and is formed into a tubular body. Accordingly, as shown in the cross-sectional view of Figure 6, the end of the horizontal member 8 coupled to the wedge to the horizontal support portion 6 is the upper and lower sides of the first and second clamps (1,2) of the horizontal support portion (6). Since it is in close contact with the outer surface, it can be more stably supported against the impact acting on the horizontal member.

In addition, as shown as a modified example in FIG. 7 , the horizontal support part 6 may be formed to horizontally extend radially outward from the outer surface of the upper end of each of the first and second clamp members 1 and 2 . have.

As described above, the clamp for fastening the horizontal member for the system according to the present invention is divided into two clamping members (1,2) and one end is rotatably connected by a hinge while the other end is disassembled with a fastening bolt and nut The fastening end (81) of the horizontal member (8) to the horizontal support (6) formed to protrude outward from the side surfaces of the first and second clamping members (1, 2). By simply and stably fastening with a wedge, it is possible to efficiently install the formwork and horizontal members for scaffolding, thereby improving work efficiency. In addition, since the clamp for fastening the horizontal member for the system according to the present invention can easily install the horizontal member with respect to the vertical supporter with a simplified structure, the manufacturing cost can be greatly reduced compared to the conventional clamp.

The clamp for fastening the horizontal member for the system dongbari of the present invention can be used to stably and simply install the horizontal member to the vertical supporter.
