Description

  The present invention relates to a support device for transport pipes and the like for supporting concrete transport pipes, various pipes, power distribution cords and the like.

  For example, in the construction of concrete structures, a concrete placement method in a high place or in a wide range is generally performed by placing a concrete transport pipe connected to a concrete pump on a slab formwork and pumping the inside of the transport pipe. The concrete is placed on the wall or slab by discharging the concrete from the tip of the transport pipe and moving the tip of the transport pipe.

  By the way, when a concrete transport pipe is piped on a slab formwork, a slab rebar is arranged on the slab formwork. The slab rebar will be damaged by the generated vibration.

  That is, there is a pulsation in the concrete pumped by the concrete pump. Therefore, the concrete transport pipe is vibrated in the length direction, and the concrete transport pipe is caused by the pressure of the concrete colliding with the bent portion of the concrete transport pipe. If such vibration, vibration, or meandering is applied to the slab reinforcing bars, the slab reinforcing bars may be damaged due to the arrangement of the bars.

  In order to prevent such damage to the slab rebar, a support frame for the concrete transport pipe is disposed on the slab form so that the concrete transport pipe does not directly contact the slab rebar.

  As shown in FIGS. 4 (a) and 4 (b), the conventional support frame 1 is formed by connecting a pair of legs 2, 2 obtained by bending a pipe into a substantially inverted U shape with a horizontal armature 3, and both legs 2, The support plate 4 that supports the concrete transport pipe A between the upper ends of the two is suspended by a chain 5 and is supported by the chain 5 that can swing freely. It is intended to absorb vibration and vibration.

  However, when the concrete transport pipe A is supported by the chain body 5, the chain body 5 swings together with the vibration and vibration of the concrete transport pipe A, so that the chain body 5 moves in the swinging direction with respect to the entire support frame 1. The movement occurs, and the support frame 1 supporting the concrete transport pipe A moves.

  By the way, the conventional support frame 1 is configured such that the lower ends of both legs 2 and 2 are placed directly on the slab form B, so that the net-like space of the slab reinforcing bar C is used as the leg 2 and the slab rebar C in actual use. When the support base 1 supporting the concrete transport pipe A is moved, the legs 2 and 2 collide with the slab reinforcing bar C, and this collision causes the slab reinforcing bar C to move. There is a problem of causing damage

  In addition, the chain 5 supporting the concrete transport pipe A has a limited swing range, and vertical motion is applied to the concrete transport pipe A in which vibration or vibration has occurred. There is a problem of becoming unstable.

  Accordingly, an object of the present invention is to make it possible to move on a slab rebar and a flat plate while supporting a concrete transport pipe and the like, and to cause vibration generated in the concrete transport pipe and the like to a slab formwork, a slab rebar and a flat plate. An object of the present invention is to provide a support device such as a transport pipe that can effectively block the concrete transport pipe and can stably support the concrete transport pipe.

  In order to solve the above-described problems, the invention of claim 1 employs a structure in which a support member such as a concrete transport pipe is provided on an upper part of a sliding member that can move in a plane on a slab reinforcing bar or the like. It is.

  According to a second aspect of the present invention, in the first aspect of the invention, the sliding member is configured to be a dish boat provided with a peripheral wall toward the upper surface around a flat bottom plate.

  The dish boat is formed by using a metal plate or a synthetic resin plate having a sufficient size in a plane, and providing an obliquely outward peripheral wall around the upper surface side of a bottom plate that is rectangular, circular, or elliptical. .

  According to a third aspect of the present invention, in the first aspect of the present invention, the sliding member is formed by connecting sleds that are arranged in parallel on both sides with a horizontal shaft.

  According to a fourth aspect of the present invention, in the first aspect of the invention, the sliding member employs a structure in which a horizontal bar is installed inside the annular body made of pipe.

  According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the support member has a shaft erected between the support members erected on both sides of the sliding member, and the concrete transport pipe is mounted on the shaft. A configuration is adopted in which a cylindrical roller that supports the like is rotatably attached in a direction allowing movement in the length direction of a concrete transport pipe or the like.

  The invention according to claim 6 is the invention according to any one of claims 1 to 4, wherein the support member has a shaft laid between the support members erected on both sides of the sliding member, and the concrete transport pipe is mounted on the shaft. A configuration is adopted in which a drum-shaped roller that supports a roller is attached so as to be rotatable in a direction permitting movement in a length direction of a concrete transport pipe or the like.

  According to the present invention, since the supporting member such as the concrete transport pipe is provided on the upper part of the sliding member that can move in a plane on the slab reinforcing bar or the like, the entire supporting device slides in all directions on the slab reinforcing bar or the like. Even if vibration or vibration of the supported concrete transport pipe or the like is added to the support device, the vibration of the support device or the transmission of vibration to the slab rebar can be effectively blocked by the sliding of the support device. The used concrete can be pumped without damaging the slab reinforcement.
