Description

Technical Field

[0001] The present invention relates to the technical field of Bailey sheet connection structures, and in particular to a lightweight Bailey sheet connection node. Background Art

[0002] The integral jacking formwork system (building machine) is often used in the wall construction of super high-rise buildings or high-rise buildings due to its advantages such as safety and efficiency. At present, the steel platform on the top of the building machine is generally connected by welding, and the platform cannot be turned around, which reduces the economy of the jacking platform. With the continuous development of building machine technology, it has become a trend to use Bailey plates as the load-bearing components of the steel platform. The platform is composed of Bailey plates in the horizontal and longitudinal directions to form the main force-bearing system. At present, the cross-shaped connection nodes between the Bailey plates in two directions are generally composed of cast steel parts, square steel pipes, etc. The nodes are heavy and the economy is poor. Due to the large number of cross-shaped nodes, the overall weight of the steel platform has not been effectively reduced.

[0003] For example, there is currently a Chinese patent authorization announcement number CN218116104U that discloses a Bailey plate combined connector. This patent has the above-mentioned disadvantage of heavy weight, and this patent cannot connect the column to the steel platform system. Summary of the invention

[0004] The purpose of the present invention is to provide a lightweight Bailey plate connection node to solve the above-mentioned deficiencies and defects in the prior art.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0006] A lightweight Bailey plate connection node has an overall straight quadrangular prism structure, wherein the bottom side and top side of the straight quadrangular prism structure are double-channel steel cross bar structures, and Bailey plate connectors are respectively provided on the side surfaces at both ends of the side edges of the straight quadrangular prism structure, and the bottom side, top side and two side edges on the same side of the straight quadrangular prism structure are respectively connected to the four vertices of a quadrilateral reinforcing web member.

[0007] In a preferred embodiment of the present invention, the double-channel steel crossbar structure comprises a pair of channel steels arranged in parallel and at intervals, and two ends of the channel steels are respectively fixed to corresponding side edges.

[0008] In a preferred embodiment of the present invention, the upper vertex and the lower vertex of the quadrilateral reinforcing web member are respectively fixed in the gaps of a corresponding pair of channel steels, and the two side vertices of the quadrilateral reinforcing web member are respectively fixed to the corresponding side edges.

[0009] In a preferred embodiment of the present invention, each side of the quadrilateral reinforcing web member is made of I-beam.

[0010] In a preferred embodiment of the present invention, a reinforcing steel sheet is provided at the connection between the channel steel and the side edge.

[0011] In a preferred embodiment of the present invention, connection holes are provided in the middle of the top end and the middle of the bottom end of the side edge.

[0012] In a preferred embodiment of the present invention, at least two Bailey sheet connectors distributed at right angles are provided at the top and bottom of each side edge.

[0013] In a preferred embodiment of the present invention, the Bailey connector is a male connector or a female connector.

[0014] In a preferred embodiment of the present invention, two male connectors and two female connectors are respectively provided at the top and bottom ends of two side edges arranged diagonally, and one male connector and one female connector are each provided at the top and bottom ends of the other two side edges arranged diagonally.

[0015] In a preferred embodiment of the present invention, two side vertices of the quadrilateral reinforcing web member are respectively fixed to corresponding side edges via a double plywood structure.

[0016] Due to the adoption of the above technical solution, the present invention has the following advantages:

[0017] (1) The node is light and economical. The weight of this node can be reduced by more than 50% compared with the existing cast steel cross node. Since there are many cross nodes in the steel platform system of the building construction machine, the amount of steel used in the platform system using this node can be greatly reduced, thereby improving the economic efficiency of the platform.

[0018] (2) Simple structure and convenient processing. The nodes are not made of cast steel, but are made of steel, which greatly reduces the difficulty of node processing. Most of the components of the nodes are made of light channel steel and I-beam, which are easy to connect and speed up the production and installation.

[0019] (3) The node structure is more reasonably stressed. Connection holes are opened in the middle of the top and bottom of the side edges, which are connected with the four conical heads on the top of the building machine columns. Compared with the current flat shelving, it can effectively transmit the horizontal shear force of the platform, with stronger connection reliability and more reasonable stress.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0029] See also Figures 1 to 6 A lightweight Bailey plate connection node is shown, which is in the form of a straight quadrangular prism structure 100 as a whole, and the bottom side 110a and the top side 110b of the straight quadrangular prism structure 100 are double-channel steel cross bar structures 120. Bailey plate connectors 140 are respectively provided on the side surfaces of the side edges 130 of the straight quadrangular prism structure 100, and the bottom side 110a, the top side 110a and the two side edges 130 located on the same side of the straight quadrangular prism structure 100 are respectively connected to the four vertices 151 of a quadrilateral reinforcing web member 150. The present invention uses a double-channel steel cross bar structure 120, which can reduce the weight by more than 50% compared with the existing cast steel cross node, and the node is light in weight and highly economical.

[0030] In this embodiment, the double channel steel crossbar structure 120 includes a pair of parallel and spaced channel steels 121, and the two ends of the channel steel 121 are respectively fixed to the corresponding side edges 130 by welding. In order to further enhance the connection strength, a U-shaped reinforcing steel sheet 122 is provided at the connection between the channel steel 121 and the side edge 130.

[0031] Preferably, the upper and lower vertices of the quadrilateral reinforcing web member 150 are respectively fixed in the gap 121a of the corresponding pair of channel steels 121, and the vertices on both sides of the quadrilateral reinforcing web member 150 are respectively fixed to the corresponding side edges 130 by welding. In order to further enhance the connection strength, the vertices on both sides of the quadrilateral reinforcing web member 150 are respectively fixed to the corresponding side edges 130 by a double plywood structure 152. In this embodiment, each side 153 of the quadrilateral reinforcing web member 150 is made of I-beams, and the nodes are not made of cast steel. All of them are made to greatly reduce the difficulty of node processing. Most of the constituent rods of the nodes are made of light channel steels and I-beams, and are easy to connect, which speeds up the manufacturing and installation speed.

[0032] Connection holes 131 are provided in the middle of the top and the middle of the bottom of the side edge 130 for socket connection with the four conical heads 210 on the top of the building machine column 200 to transmit vertical pressure and horizontal shear force. At the same time, tension bolts are arranged at positions corresponding to the column bolt holes 220 on the building machine column 200 to transmit vertical tension. In this way, the building machine column 200 can be connected to the steel platform system.

[0033] At least two right-angled Bailey sheet connectors 140 are provided at the top and bottom of each side edge 130, and the Bailey sheet connectors 140 are male connectors 141 or female connectors 142. In this embodiment, two male connectors 141 and two female connectors 142 are provided at the top and bottom of the two side edges 130 arranged diagonally, respectively, and one male connector 141 and one female connector 142 are provided at the top and bottom of the other two side edges 130 arranged diagonally.
