Abstract

(57) [Abstract] [Purpose] A scaffolding plate support bracket 3 that is vertically attached to a steel wall 1 used during the construction of a steel ship to reduce the risk of installation and removal work at high places, Socket-type scaffolding board support metal fittings for the purpose of making it possible to attach and detach with simple work. [Structure] An L-shaped steel bracket 2 welded and attached to a steel wall 1, a scaffolding plate support member 3 in which a socket portion 4 is welded to an end portion in the longitudinal direction with one surface of a chevron billet horizontal, A socket-type scaffolding plate support fitting composed of a stopper bolt 5 and a nut 7 which are arranged in FIG.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a supporting metal member for a scaffolding plate for construction, which is attached to a hull outer plate, a steel wall, or a reinforcing material thereof during the construction of a steel ship. The present invention relates to a detachable scaffolding board support fitting.

[0002]

[Prior Art]

 Conventionally, as this type of scaffolding plate support metal fitting, a rectangular bracket 23 having a plurality of bolt through holes 22 is welded to a steel wall 21 as shown in FIG. 2, and the above bolt is attached to one end of a chevron-shaped steel piece. A scaffolding plate support member 26 to which an elbow plate portion 25 having a through hole 24 that overlaps the through hole 22 is fixed is known.

[0003]

[Problems to be solved by the device]

 According to the conventional technique, a scaffolding plate support is applied at a predetermined position, and a bolt is welded to a bolt through hole of an elbow plate portion of the scaffolding plate supporting end and a steel wall. Even when the bolts are inserted through the bolt through holes of and the bolts are tightened and removed with the nuts, the bolts must be loosened and pulled out while holding the scaffolding plate support material. There was a problem that the work was dangerous, and also that the bolts and nuts after removal were frequently lost.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to support the scaffolding plate support during mounting and removal of the scaffolding plate support. It is intended to provide a scaffolding plate support fitting that does not require holding of materials and does not require bolt extraction work at high places.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the scaffolding plate support metal fitting of the present invention comprises an L-shaped steel bracket to be welded and attached to a steel wall and a longitudinal end portion in which one surface of a chevron steel piece is horizontal. A scaffolding plate support member formed by welding a short width surface of a steel socket portion, which is screwed with a stopper bolt and has a nut welded to a stopper bolt insertion hole, and the socket portion of the scaffolding plate support member is It is attached to the L-shaped steel bracket from above and can be fixed or removed by tightening or loosening the stopper bolt.

[0006]

[Action]

 To fix the scaffolding plate support material to the L-shaped steel bracket, first, just fit the socket part of the scaffolding plate support material to the L-shaped steel bracket, and it is not necessary to hold the scaffolding plate support material. become.

With respect to the stopper bolt of the socket portion, the inner wall of the socket portion is attracted to the L-shaped steel bracket by tightening the stopper bolt.

[0008]

【Example】

 Examples will be described with reference to the drawings.

In FIG. 1, one end of an L-shaped steel bracket 2 is welded to a steel wall 1.

The scaffolding plate support member 3 has one horizontal surface of the chevron steel piece as an upper part, and one end of the chevron steel sheet with one surface of a short width surface of the socket portion 4 fitted to the above L-shaped steel bracket. Weld.

An insertion hole 6 for the stopper bolt 5 is provided at approximately the center of one surface of the long width surface of the socket portion 4, and a nut 7 screwed to the stopper bolt 5 is welded to the insertion hole 6.

The stopper bolt 5 is screwed into the nut 7, the socket portion 4 is fitted into the L-shaped steel bracket 2, and the stopper bolt 5 is manually rotated to make the scaffold plate support member 3 into an L-shaped shape. It is fixed to the steel bracket 2.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. The stopper bolt is screwed into the nut of the socket, and the stopper bolt is rotated with a spanner or an adjustable wrench to weld the scaffolding plate support material to the steel wall. It can be easily fixed to a bracket made of steel and can be easily removed, and the risk of mounting and removing at high places can be greatly reduced.
