  However, in the clamp device as described in Patent Document 1, the scaffold pipes are combined while being displaced at the connection point. Specifically, two scaffold pipes are combined in a cross shape by the clamping device. Therefore, the connected scaffold pipes are inconsistent, which is inconvenient for the structure of the scaffold, and the end of the scaffold pipe is exposed at the place where the end of the scaffold pipe is fixed, which is dangerous.

  Accordingly, the present invention provides a clamp device for a pipe assembly such as a clamp device for a temporary scaffolding pipe that can be connected in a stable state so that the pipes such as scaffolding pipes are not stepped, and a pipe assembly using such a clamp device. The purpose is to provide.

In order to achieve this object, the clamp device for a pipe assembly of the present invention integrates a plurality of connection clamps that are fitted to the outer periphery of the pipe and tightens the pipe, and a plurality of pipes are connected and fixed to form a pipe assembly. Each of the coupling clamps is configured such that the bases of a pair of clamp pieces (clamp members) are hinge-coupled and the opening side of the clamp pieces can be clamped by a clamping means. Each of the pair of clamp pieces is formed in an annular shape so that the axes of the pair of clamp pieces are orthogonal to each other, and one of the connection clamps is formed so that the inner periphery of the pair of clamp pieces is tightened with a round member. Round connecting clamps, and the remaining connecting clamps are corners formed so that the inner periphery of the pair of clamp pieces clamps the square member. A coupling clamp, but such. In addition to temporary scaffolding, the pipe assembly includes furniture such as partitions and partitions. In addition, the clamp device for a temporary scaffold pipe according to the present invention for achieving this object is provided by integrating a plurality of connection clamps that are fitted to the outer periphery of the scaffold pipe and tighten the scaffold pipe, and connecting and fixing the plurality of scaffold pipes. A clamp device for a temporary scaffold pipe constituting a temporary scaffold, wherein each of the connection clamps is hinged to a base portion of a pair of clamp pieces, and the opening side of the clamp pieces can be tightened by a fastening means, for example Each of the pair of clamp pieces is formed in an annular shape so that the axes of the pair of clamp pieces are orthogonal to each other, and one of the connection clamps is formed so that the inner periphery of the pair of clamp pieces is tightened with a round member. Round connecting clamps, and the remaining connecting clamps are formed so that the inner periphery of a pair of the clamp pieces clamps square members. In the form coupling clamp it is things like. The axis of the pair of clamp pieces is the axis when the clamp piece is closed or the axis of the pipe or scaffold pipe when the pipe or scaffold pipe is tightened with the pair of clamp pieces. Here, the pipes or scaffolding pipes fixed to the respective connection clamps are connected in a state where the axes are orthogonal to each other. One of the plurality of connection clamps is a round connection clamp formed so that the inner periphery of the pair of clamp pieces is a round member (having a circular cross section). In the round connection clamp, for example, the inner periphery of a pair of clamp pieces is circular in a tightened state. The remaining connection clamps are square connection clamps formed so that the inner periphery of the pair of clamp pieces clamps a square member (cross-sectional square shape, for example, a square shape). In the square connection clamp, for example, the inner periphery of the pair of clamp pieces is square, for example, square in a tightened state. Here, for example, a vertical pipe having a circular cross section extending in the vertical direction is tightened with a round connection clamp, and a square cross section extending in the horizontal direction, for example, a square horizontal pipe is tightened with a square connection clamp. For example, only the end of the horizontal pipe is formed in a square cross section, and the other part is formed in a circular cross section. For example, the vertical pipe is loosely tightened with a round connection clamp, and the clamp device is rotated around the vertical pipe so that the square connection clamp is in an appropriate position and is fitted to the end of the horizontal pipe.
Then, the vertical pipe is tightened with the round connection clamp, and the end of the horizontal pipe is tightened with the square connection clamp. Since the square connecting clamp is fitted to the end of the horizontal pipe in a non-rotating state, the horizontal pipe does not rotate and is not twisted, so that a stable pipe assembly can be constructed.

  In the present invention, a plurality of connecting clamps can be integrated in a fixed state.

  In addition, the pipe assembly of the present invention, for example, a temporary scaffolding, includes a vertical pipe extending in the vertical direction, such as a vertical vertical pipe, a horizontal pipe extending in the horizontal direction, such as a horizontal scaffolding pipe, and a plurality of connection clamps for tightening the pipe. A pipe assembly including a clamp device for a pipe for connecting and fixing the vertical pipe and the horizontal pipe, for example, a clamp device for a scaffold pipe, wherein each of the connection clamps is a pair of clamps. The base of the piece is hinged, and the opening side of the clamp piece can be tightened by the fastening means, and the axis of each of the pair of clamp pieces is provided to be orthogonal, One of the connection clamps is a round connection clamp formed so that the inner circumference of the pair of clamp pieces clamps a round member, and the remaining front The connection clamp is a square connection clamp formed so that the inner periphery of the pair of clamp pieces clamps a square member, the vertical pipe, for example, the scaffold vertical pipe is round, and the horizontal pipe, for example, the scaffold horizontal pipe is Having a square end, the round connection clamp tightens the vertical pipe, eg a scaffold vertical pipe, and the square connection clamp fastens the square end of the scaffold horizontal pipe, eg a scaffold horizontal pipe And so on.

  The horizontal pipe, for example, the scaffold horizontal pipe, is preferably formed in a round shape except for the square end.

  A joint having insertion pipes protruding from both sides of an intermediate member having an outer surface with a square cross section can have a structure in which horizontal pipes having square end portions are connected to each other.

  Further, reinforcement can be performed by arranging a bracing pipe between the vertical pipe and the horizontal pipe. The bracing pipe can have the same structure as the horizontal pipe, but two round connection clamps are provided so that the axis of each pair of clamp pieces is orthogonal, and the crossing angle of the axis is changed. The joint may be connected to the square end of the bracing pipe so that the round pipe protrudes from the square end so that the connection clamp can be used.

  By using the clamping device for a pipe assembly or the clamping device for a temporary scaffolding pipe of the present invention, the pipe or the scaffolding pipe can be connected so that no step is generated and the horizontal pipe is not easily turned or twisted. The pipe assembly or the temporary scaffold can be configured safely and stably. Further, the pipe assembly and the temporary scaffold according to the present invention have a safe and stable configuration.
