Description

{Connectors for erection fixture}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a scaffold that can be applied to a scaffold or a simple structure to be applied to a construction site or an industrial field and more particularly to a connector for a scaffold or a simple structure, It is possible to easily provide a horizontal member or an inclined member to be assembled in the direction of a vertical axis, and in particular, to provide a connecting structure for a new structure in which four or more horizontal members and vertical members can be simultaneously applied.

 Scaffolding or simple structures to be applied to a construction site or an industrial site are provided. In the case of these scaffolds, a connecting member for a scaffold is provided so as to join the horizontal member and the inclined member to a vertical member serving as a support.

A representative example of a joint which is generally applied to a scaffold is a steel pipe scaffolding connector of Korean Registered Patent Publication No. B1- 10-1581540 (2015.12.30.), Which is composed of an outer side of a vertical steel pipe constituting a pillar of a scaffold And a wedge hole which is attached to both ends of a horizontal steel pipe horizontally connected between the vertical steel pipes and is coupled to the flange bracket by a wedge, the flange bracket being radially attached to the flange bracket, And a crevice formed in the pipe; The flange bracket is provided with a mounting hole on the left and right outer sides of the wedge hole, a mounting protrusion on the mounting hole is formed on the top end of the top plate of the crevice, And a supporting portion which is in contact with an outer circumference of the lower plate and extends to the front of the lower plate to bend vertically downwardly and a support surface which extends to the left and right sides of the lower plate and is bent downward vertically, As shown in Fig.

In the case of the above-described construction, the flange bracket can not be moved in the field because the flange bracket is required to be fixed to the column, and if the flange bracket is damaged, the entire column must be disposed. So that it is impossible to install it at various angles according to the developing conditions.

Another example is a flange for a system scaffold of Korean Registered Patent Application No. B1-1459076 (Nov. 11, 2014), which is constituted by a flange provided with a first clamp body and a second clamp body, The first clamp body has a plurality of wedge joint holes formed on an upper surface thereof, an inscribed surface which is tightly fixed to the vertical pipe at a center of the first clamp body, a shaft having a shaft connection hole formed at the rear thereof, The adjusting bolt is formed with a shaft portion at the end thereof with a shaft hole as a shaft pin and a screw portion having a nut fastened to the outer circumferential surface thereof is formed at an end portion of the connecting bolt, The second clamp body has a plurality of wedge joint holes formed on an upper surface thereof. The second clamp body has an inner surface formed in a center of the first clamped body, A structure is formed, and forms a locking step open to allow the nut of the adjusting bolt in the front catch configuration.

Since the flange is configured to be separated from the vertical pipe, it is convenient to move the flange to various positions. However, since the assembly of the horizontal and the inclined members is made by the wedge as in the conventional case, It was impossible to install at an angle.

KR 101581540 B1 2015.12.30. KR 101459076 B1 2014.11.12.

Accordingly, the inventor of the present invention has researched various problems related to the connection of the horizontal member and the inclined member to the vertical member applied to the scaffold or simple structure applied to the above-mentioned construction site or industrial field.

In other words, since the horizontal member and the inclined member, which are conventionally applied to the scaffold or the like, are fixed to the flange welded to the vertical member by using the wedge in a fitting state, It is not possible to install the flange in a position corresponding to the site. In particular, it is possible to apply only the inclined member to which the coupling hole is attached at a specific angle. However, in the present invention, by using the wrench bolt It is possible to fix the connecting body in various positions and the wrench bolts and the horizontal and inclined members are assembled by using hinge type connecting means so that at least four horizontal and inclined members can be simultaneously applied, The angle can be adjusted in various ways to suit the site conditions. The present invention has been completed based on the technical problem of the present invention.

According to an aspect of the present invention, there is provided a connection for a scaffold for connecting a horizontal member and a slant member to a vertical member constituting a first scaffold; A connector body assembled to be movable in the longitudinal direction on the vertical member; A wrench bolt installed on the connecting port body to fix the connecting port body to the vertical member; And hinge type connecting means for connecting the horizontal and the inclined members to the wrench bolt; The connecting means includes first and second fixed hinge pieces fixed to the horizontal and the inclined members, a third fixed hinge piece sandwiched between the first and second fixed hinge pieces, a hinge pin extending through the first to third fixed hinge pieces, ≪ / RTI > And the third fixed hinge piece is formed so as to be connected to the hinge pin at a right angle and to be coupled to the wrench bolt.

Secondly, the wrench bolt installed in the connector main body is fastened to a nut inserted into a hole in the nut formed at the vertical member assembler in the center of the connector main body.

Third, the wrench bolt installed in the connector body is fastened to a nut inserted into a hole formed in a nut formed by a nut housing coupled to the outer periphery of the connector body, and a wrench bolt inner hole is formed in the connector body, And the tip of the bolt is pressed against the vertical member.

Fourth, a connecting member for connecting a horizontal member and an inclined member to a vertical member constituting the scaffold; A finishing cap covering the top of the vertical member; A connection port body including a ring-shaped support formed below an edge of a circular plate coupled to the finishing cap; A wrench bolt assembled to the support at right angles to the vertical member; And hinge type connecting means for connecting the horizontal and the inclined members to the wrench bolt; The connecting means includes first and second fixed hinge pieces fixed to the horizontal and the inclined members, a third fixed hinge piece sandwiched between the first and second fixed hinge pieces, a hinge pin extending through the first to third fixed hinge pieces, ≪ / RTI > And the third fixed hinge piece is formed so as to be connected to the hinge pin at a right angle and to be coupled to the wrench bolt.

Fifth, the wrench bolt provided on the support body of the connector body is fastened to a nut inserted into a hole formed in the nut formed by the nut housing coupled to the outer periphery of the support body.

Sixth, the nut housing is welded to the outside of the support body and is coupled to a ground plate having a latching groove to be inserted into the tip of the wrench bolt; And the bolt assembly hole is opened downwardly opposite to the original plate so that the bolt assembly hole can be easily assembled to the bolt assembly hole even when the nut is assembled to the wrench bolt.

Seventh, in the connecting means, a pin hole and a screw hole are formed in the first and second fixed hinge pieces, respectively, and a bolt is formed at the tip of the hinge pin so that the hinge pin is screwed.

The use of the connector for scaffolds provided in the present invention has the following effects.

- It is possible to simplify the volume during storage and transportation by fixing the connecting body to the vertical member without welding.

- Since the connector body is slidably assembled to the vertical member, it is easy to install and move to various positions.

- The assembly of the connector main body and the horizontal and inclined members is made by the hinge-type connecting members, and it is possible to install the inclined members in various angles.

- Installation and dismantling can be done only with a hexagonal stove.

Four or more horizontal and inclined members can be assembled simultaneously on the vertical member.

- Since each component is constructed as a prefabricated structure, maintenance is possible at low cost.
