Description

CLAMP ASSEMBLY FOR SCAFFOLDING}

The present invention relates to a clamp assembly for scaffolding, and more particularly, to provide an improved clamp assembly for easily fixing a scaffold pipe installed in a longitudinal direction and a lateral direction when constructing a building or various structures.

When constructing civil and building structures such as buildings or bridges, it is made of metal material to support the formwork to build the structure or to install safety nets to prevent foreign objects or work tools from falling during the work for external construction. It is a scaffold to install the made scaffolding pipe at regular intervals in the vertical and horizontal directions.

Clamp assemblies are used to bind the scaffold pipes to each other, and a large number of clamp assemblies have been developed and used for this purpose in the past, and the present applicant also applies a patent (No. 2007-102103) in advance. The contents thereof have been described with reference to FIG. 1.

The clamp assembly (1) to which the prior art is applied has a support (2) in an arc shape so that a metal material having a semicircular cross section becomes an inner surface where the plane is connected to the scaffolding pipe.

An upper side of the support port (2) is provided with a support port (2) and the hinge (3) is provided with an open and closed arc-shaped intermittent opening (4), the support port (2) and the intermittent opening (4) The front side of the fastening brackets (5,6) are integrally formed to protrude.

The clamping brackets 5 and 6 form a screw hole 7 and a bolt hole 8 so as to be interrupted by the intermittent bolt 9 to constitute the one clamp 10.

In the first clamp 10, the two clamps 11 having the same shape as the first clamp 10 are connected to the fixing means 12 in the perpendicular direction so that the scaffold pipes can be connected in the 90 ° direction, so that they are fixed or rotatable. It consists.

Since the conventional clamp assembly is constructed in a state in which the round bar is drawn in a semi-circular shape by drawing a round bar, the process of making the supporting and intermittent holes constituting the clamp is not only complicated and difficult, but also reduces the overall productivity. .

This makes it more difficult to be more productive since the finer anti-slip protrusions must be formed on the inner surface of the support hole, as well as the non-slip protrusions have a disadvantage in that the scaffolding pipe does not properly grasp the movement or slipping phenomenon.

Since the clamp is composed of a pair of one clamp and two clamps connected to each other, it is necessary to form a separate portion for connecting the first and second clamps, and it becomes difficult to fix and fix the method.

In addition, the configuration of the hinge portion of the clamp is complicated, the process of making the entire clamp is not naturally made, as well as the connection state of the hinge portion is weak, making it difficult to crack down and secure the scaffolding pipe in the fixed state There is a problem in that the rotational state of the intermittent port is not easy.

In addition, since the half acupuncture and the intermittent ball are made by the intermittent bolts to substantially perform the intermittent operation in the state in which the scaffolding pipe is accommodated, various problems occur such that it is difficult to fasten the intermittent bolts.

Therefore, the present invention was devised to solve the above problems, and the 90 ° direction of the 1,2-clamp consisting of a support hole for placing and supporting the scaffold pipe and an intermittent hole covering the scaffold pipe placed in the support hole are covered. In the clamp assembly is configured to be coupled to the rotating or fixed state by the intermittent means;

The support port is forging and forming a round bar of a metallic material in an arc shape, and the interruption port is formed by forming a metal plate material so that the inner side of the scaffold pipe is connected with an open surface and the outer side with a closed surface to form an inner end of the support port and the intermittent port. Is connected to the hinge, the closing surface of the intermittent opening of the hinge position is formed to the center of the hinge to open so that the scaffolding pipe can enter and exit when opening the intermittent opening, and the scaffolding pipe is accommodated at the outer end of the support and the intermittent opening The purpose is to have a sufficient strength and durability while providing the convenience of use by providing a fastening means for fixing the support and the intermittent of the.

The present invention as described above is made of a clamp assembly, while the scaffolding pipe is substantially settled under the high load, and the support port is formed by forging with a round bar, and the intermittent port covering the support port to control the scaffolding pipe is made of a plate. It is designed to have various effects, such as increasing the overall productivity while providing the ease of use and satisfying sufficient strength to increase the convenience of users.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

The conventional clamp assembly 100 is composed of a support hole 102 for placing and supporting the scaffold pipe 101 and an intermittent hole 103 for covering and covering the scaffold pipe 101 placed in the support hole 102. .

In the present invention, the support hole 102 is formed by forging a circular rod of a metallic material in an arc shape, and the intermittent hole 103 is formed by forming a metal plate to form a cross-sectional shape, so that the scaffold pipe 101 is connected to an inner side thereof. With the open surface 104 and the outer side is configured to have a closed surface 105, the inner end (106, 107) of the support 102 and the intermittent opening 103 is connected to the hinge 108.

The occlusion surface 105 of the intermittent port 103 at the hinge 108 position is extended to the center of the hinge 108 and is not completely opened when the intermittent port 103 is opened. It can be opened just enough to allow quick clamping, such as to facilitate interruptions.

Fastening means 111 for fixing the support hole 102 and the control device 103 in a state in which the scaffold pipe 101 is accommodated at the outer ends 109 and 110 of the support device 102 and the control device 103. Equipped.

The fastening means 111 is coupled to the locking groove 112 formed in the outer end 109 of the support hole 102 and the bolt hole 113 formed in the outer end 110 of the intermittent hole 103. It is provided with an intermittent bolt 115 that is intermittent with the nut 114.

The locking hole 116 is formed to be caught in the locking groove 112 at the head position of the intermittent bolt 115, and the bolt hole 113 to which the intermittent bolt 115 is coupled is hinge 108. It is provided with a clamp 117 by forming a long hole so that the opening and closing the intermittent opening 103 to move around the intermittent bolt 115 freely.
