Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pillar for a handrail that is temporarily fixed to a beam steel frame or the like corresponding to the floor peripheral portion during the construction of a reinforced concrete building.

[0002]

[Prior art]

 Conventionally, during construction of reinforced concrete buildings, when installing handrails at the position corresponding to the floor peripheral part, ropes are stretched between steel columns, struts are temporarily welded to beams, bolts and nuts and various clamps are used. A large number of stanchions are erected, and a rope is stretched between each stanchion to make a temporary handrail.

[0003]

[Problems to be solved by the device]

 As in the prior art, when a rope is stretched between the steel columns, the central portion of the rope hangs down due to the large spacing between the steel columns, and it often does not function sufficiently safely as a handrail. In addition, when a pillar is fixed by welding, or a bolt and nut or a clamp is used as a pillar for a handrail, it takes a lot of time to attach and detach the pillar, which results in poor workability. Therefore, an object of the present invention is to provide a pillar that can be easily attached to and detached from a steel beam or the like so that a rope as a handrail can be stretched to a predetermined height.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a supporting column for handrails that is used by standing upright on a beam steel frame or the like during construction. A support rod to be inserted into is attached to the support rod, and the cylinder is fitted to the outer periphery of the support member slightly above the support rod so that it can be moved up and down, and it is inserted into the fixing hole provided on the side surface of the beam steel frame etc. A screw rod was provided, and a stopper having an L-shaped cross section was provided on the cylindrical portion above or below the screw rod. Then, the screw rod is fixed to the beam steel frame or the like with a nut so that the stopper can bite into the support member so that the support member can be fixed. Also, the strut members, cylinders and stoppers that make up the strut for handrails can be made of iron and can be used repeatedly, or a clasp for holding the rope can be provided at the upper end of the strut member to hold and remove the rope. Can be made easier.

[0005]

[Action]

 When the support for the temporary handrail of the present invention is erected on the beam steel frame, etc., insert the support rod into the support hole provided on the side face of the beam steel frame, etc. Adjust the vertical position of the cylinder according to the provided fixing hole, pass the screw rod through the fixing hole, and screw the nut into the screw rod protruding to the opposite side of the fixing hole to fix. When the nut is screwed in, the nut is strongly screwed in so that the tip of the stopper having an L-shaped cross section can be bitten into the support member, and the support member can be firmly fixed without wobbling. Also, by removing the nut, the column can be easily removed from the beam steel frame.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 and 2, but the present invention is not limited to this embodiment. The support for the temporary handrail has a support rod 2 projecting near the lower end of a pipe-shaped support member 1 fixed to a beam steel frame or the like, and the support rod 2 is a support hole provided on a side surface of the beam steel frame 3 or the like. The support member 1 can be fixed to a beam steel frame or the like by inserting the support member 1 into the beam 3a. A support plate 2a is provided on the support rod 2 so that the support rod 2 is prevented from rattling when inserted into the support hole 3a. Further, a stopper metal 4 formed in an elliptical spiral shape of about two turns is provided on the upper end of the column member 1 so that a rope or the like can be held and easily removed. Note that a pipe-shaped handrail bar may be attached without providing the stopper plate 4 on the upper end of the support column member 1.

A cylindrical body 5 is vertically movably fitted to the outer circumference of the pillar member slightly above the lower end of the pillar member 1, and is inserted into the fixing hole 3b provided on the side surface of the beam steel frame or the like on the outer circumference of the cylindrical member 5. A fixing screw rod 6 is provided so as to project. The cylindrical body 5 can be moved up and down in order to cope with the positional change of the fixing hole 3b into which the screw rod 6 is inserted. In addition, the cylindrical body 5 is provided with a stopper 7 having an L-shaped cross section at an upper position above the fixing screw rod 6 and an upper end projecting portion directed toward the projecting side of the screw rod. . The pillar member 1, the support rod 2, the cylindrical body 5, the screw rod 6 and the stopper 7 are all made of iron, but it is possible to form a part of the component member with other metal or resin having high strength. . Further, the stopper 7 is elastically deformed when the upper end is pushed and can be slightly bent as shown by the arrow in FIG. 2, and the end can be bited into the column member 1.

In the above description, the tubular body 5 can be rotated around the outer periphery of the column member 1, but a guide rail and a groove are formed between the tubular body 5 and the outer periphery of the support column member 1 to support the screw rod 6. The rod 2 may be oriented in the same direction so that only vertical movement is possible. Further, the stopper 7 may be provided on the lower cylindrical portion of the screw rod 6 upside down. When the support for the temporary handrail is fixed to the beam steel frame or the like, the support rod 2 is inserted into the support hole 3a on the side surface of the beam steel frame, and at the same time, the screw rod 6 is inserted into the fixing hole 3b, and the screw rod 6 is inserted. By screwing a nut into the tip protruding from the beam steel frame to the back, the stopper 7 can be bent and the tip bites into the outer peripheral surface of the pillar member 1 to firmly fix the pillar member 1 without rattling. it can.

[0009]

[Effect of device]

 The support for the temporary handrail of the present invention can fix the support member by inserting the support rod into the support hole such as a beam steel frame and inserting the screw rod into the fixing hole and screwing the nut. Also, since it is only necessary to remove the nut and pull out the two insertion parts, it is easy to install and remove. Further, at the time of mounting, the stopper is bited into the outer peripheral surface of the support member by screwing the nut, so that the support member can be fixed without rattling.
