Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cross bar connecting device. Background Technique

[0002] The socketed steel tubular falsework is a modern building construction support system. It adopts modular design and is composed of standard steel pipes, horizontal bars, diagonal bars and connectors. A stable structure is achieved through socket connections. Its installation is convenient. Only need to insert the steel pipe into the connector and fix it, eliminating the welding process, reducing labor intensity and construction period. The socketed steel tubular falsework has good load-bearing capacity and stability, can bear large loads and wind forces, and can be flexibly adjusted and combined according to needs to adapt to various construction environments. Due to its advantages of high efficiency, safety, economy and environmental protection, the socketed steel tubular falsework is widely used in the fields of building construction, decoration and maintenance.

[0003] For example, a socketed steel tubular falsework connecting component disclosed in Chinese Patent Publication No. (CN218522209U) records: "This solution realizes the rapid assembly of pipe fittings through structural design. It does not require the use of multiple angle steels for fixation, and the fixation effect is better. At the same time, the designed connector is entirely located inside the pipe fitting, so the aesthetics after connection is better and the outer surface is smoother", and also records: "There is a support gap between the connecting rod and the support keel in this connection structure, which is prone to shaking. Secondly, the pin of this structure needs to be installed separately, and the assembly is relatively complex" technical problems.

However, due to the large amount of work during the installation of the falsework, the long-term repeated installation will cause the omission of the limit pin.

[0037] Specifically, the clamping component includes a U-shaped clamping plate 7 and an insertion positioning hole 8. The two ends of the crossbar 2 are respectively fixedly connected with a U-shaped clamping plate 7. The U-shaped clamping plate 7 is clamped and connected to the surface of the disk buckle connector 5. The insertion positioning hole 8 is arranged through the upper and lower surfaces of the U-shaped clamping plate 7, and the insertion positioning hole 8 is longitudinally axially symmetrically arranged with the insertion locking hole 6.

[0038] Specifically, the insertion positioning component includes a conical insertion rod 9, a top pressing plate 10 and an arc-shaped avoidance groove 11.

[0039] Through the above structural design, when in use, one end of the crossbar 2 is docked with the disk buckle connector 5 on the surface of the vertical rod 1 through the U-shaped clamping plate 7, and at the same time, the insertion locking hole 6 and the insertion positioning hole 8 are axially aligned up and down. After the docking is completed, the conical insertion rod 9 is inserted into the middle of the insertion locking hole 6 and the insertion positioning hole 8, and then one end of the crossbar 2 can be connected and locked with the vertical rod 1 through the conical insertion rod 9.

[0040] Embodiment 2:

[0041] The crossbar connection device provided in Embodiment 1 is further optimized. Specifically, as Figures 4-5 shown, the locking assembly includes a turning shaft rod 12, a turning plate 13, and a trapezoidal clamping block 14. The middle part of the turning shaft rod 12 is fixedly connected symmetrically with a turning shaft rod 12. The surfaces of the two turning shaft rods 12 are respectively rotatably connected with a turning plate 13. The surfaces of the two turning plates 13 facing away from each other are respectively fixedly connected with a trapezoidal clamping block 14.

[0042] Specifically, the reset assembly includes a lifting guide rod 15, a top extrusion disc 16, an annular fixing seat 17, an extension connecting rod 18, a fixing block 19, and a reset spring 20. A lifting guide rod 15 is slidably connected to the middle parts of the conical insertion rod 9 and the top extrusion plate 10. The top of the lifting guide rod 15 is fixedly connected with a top extrusion disc 16. The end of the lifting guide rod 15 away from the top extrusion disc 16 is fixedly connected with an annular fixing seat 17. The surfaces of the annular fixing seat 17 are symmetrically hinged with two extension connecting rods 18. The ends of the two extension connecting rods 18 facing away from each other are respectively hinged to the surfaces of the two turning plates 13 facing each other. A fixing block 19 is fixedly connected to the surface of the lifting guide rod 15. A reset spring 20 is sleeved on the surface of the lifting guide rod 15.

[0044] Through the above structural design, when the conical insertion rod 9 is inserted into the insertion locking hole 6 and the insertion positioning hole 8, the trapezoidal clamping block 14 is squeezed and contracts into the arc-shaped avoidance groove 11. At the same time, the turning plate 13 is pushed to turn into the arc-shaped avoidance groove 11. When the turning plate 13 turns into the arc-shaped avoidance groove 11, the lifting guide rod 15 is pulled downward through the extension connecting rod 18, so that the reset spring 20 is stretched downward. Until the top end of the trapezoidal clamping block 14 moves below the U-shaped clamping plate 7, the reset spring 20 pulls the lifting guide rod 15 upward, and the extension connecting rod 18 pushes the turning plate 13 outward. When the turning plate 13 moves, it pushes the trapezoidal clamping block 14 out of the middle of the arc-shaped avoidance groove 11 to below the U-shaped clamping plate 7, so as to complete the automatic locking of the vertical rod 1 and the crossbar 2. When the vertical rod 1 and the crossbar 2 are disassembled, the top extrusion disc 16 is pressed downward to make the lifting guide rod 15 move downward. During the movement of the lifting guide rod 15, the middle part of the extension connecting rod 18 is pulled downward through the annular fixing seat 17. The reset spring 20 is stretched while the lifting guide rod 15 moves. At this time, the turning plate 13 drives the trapezoidal clamping block 14 to turn into the arc-shaped avoidance groove 11. After completion, the conical insertion rod 9 can be pulled out from the middle of the insertion locking hole 6 and the insertion positioning hole 8, and then the vertical rod 1 and the crossbar 2 can be disassembled and separated.
