Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a scissor brace node connection device for a deep foundation pit concrete inner support beam column pile lattice column reinforcement. Background Art

[0002] With the development of urban construction and the exploitation and utilization of underground space, deep foundation pit construction has also become a common phenomenon. The supporting connection structure in traditional deep foundation pits is mainly composed of internal supports and lattice columns. Since the internal support beams and lattice columns in the supporting connection structure in the foundation pit are densely distributed and are subjected to large stress, scissor braces are usually set between the lattice columns to enhance the stability and rigidity of the lattice columns and ensure that they do not deform.

[0003] Especially in deep foundation pits, trestles are used for earthwork construction. To ensure the safety of soil transportation, multiple scissor braces are used to reinforce the lattice columns. Such scissor braces usually use connecting plates to directly weld the steel plates between the lattice columns. However, due to the influence of the main structure, the lattice columns are irregularly distributed and the sides of the columns are not on the same side, resulting in insufficient welding length between the connecting plates and the lattice columns, which seriously affects the force of the scissor braces, making the connected columns poor in integrity and posing a greater safety risk. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a lattice column reinforced scissors brace node connection device for supporting beam columns and piles in deep foundation pit concrete, so as to solve the technical problem of insufficient welding length between the connecting plate and the lattice column due to irregular distribution of the lattice columns and the side faces of the columns not being on the same side.

[0008] A connecting plate is provided between two adjacent lattice columns, and an end of the connecting plate is fixedly connected to the connecting structure.

[0009] The beneficial effects of the above technical solution are: the connecting member is a tubular structure that is transparent from top to bottom, which enhances the overall stability of the structure and can better share the load. At the same time, the first half connecting member and the second half connecting member of the connecting member are fixedly connected to the lattice column through the connecting structure, so that the node has stronger connection strength and stability.

[0010] Furthermore, the lattice column is provided with two upper and lower connecting members, and the connecting members on two adjacent lattice columns are fixedly connected by connecting plates that are arranged in an X shape and cross each other.

[0011] Beneficial effect: By fixing the connection through the connecting plates arranged in an X shape, the structure can more evenly distribute the load when facing lateral force, reduce the deformation and displacement of the nodes, and alleviate the stress concentration of the structure.

[0012] Furthermore, a first long hole that is transparent to the left and right is opened on the side of the first half connecting member, and a second long hole that is transparent to the left and right is opened on the side of the second half connecting member. The first long hole and the second long hole are both inserted with matching third bolts.

[0013] Beneficial effect: By inserting the adapted third bolt, a more flexible adjustment of the connection is achieved, and the position of the connecting member can be adjusted within a certain range to meet the construction requirements under different conditions.

[0014] Furthermore, two upper and lower parallel adjustment slots are provided on the left and right ends of the connecting plate. The connecting plate on the left is fixedly connected to the first half connecting member by a third bolt passing through the adjustment slot and the first long hole in sequence. The connecting plate on the right is fixedly connected to the second half connecting member by a third bolt passing through the adjustment slot and the second long hole in sequence.

[0015] Beneficial effect: By using the adapted third bolt to fix the first half connecting member to the second half connecting member, fine-tuning can be performed in multiple directions to ensure the accuracy and stability of the connection.

[0016] Furthermore, the side structure of the connecting member is square.

[0017] Beneficial effect: The square structure provides a larger support area.

[0019] Beneficial effect: The setting of the connecting ear plate provides more connection points, which are then connected using suitable bolts, thereby realizing the detachability of the connection structure and facilitating the installation and disassembly of the connecting components. At the same time, multiple connecting ear plates are provided to ensure the safety of the connecting components during use. BRIEF DESCRIPTION OF THE DRAWINGS
