Description

Technical Field

[0001] The invention belongs to the technical field of reinforcing support pillars, and in particular relates to a connection node for a structural reinforcement and reconstruction back-to-top device. Background Art

[0002] In construction projects, there is often a need for structural reconstruction and reinforcement. Usually, the reinforcement is to set up or add a return top support under the stress point of the roof to support the stress point. The connection node where the top of the return top support directly contacts the roof is usually a plate that directly contacts the roof. Since the roof may be uneven or the stress point is rugged, the plate is unevenly stressed when it contacts the roof, which will also cause uneven stress on the return top support below, resulting in the support being skewed, which in turn leads to poor reinforcement effect.

[0003] However, if a smaller plate is used to contact the roof, the contact area will be too small, resulting in reduced support and reinforcement stability between the roof and the roof. For this reason, a connection node for structural reinforcement and transformation of the return-to-top device is proposed, which increases the number of connection nodes between the return-to-top device and the roof and provides a stable support and reinforcement effect.

The honeycomb node stabilization zone 7 is formed by the connecting rod 292 and the second fixing plate 293 in the honeycomb node contact reinforcement zone, and multiple support connection nodes that can contact the roof are formed again, so as to realize further support for the roof in the reinforcement and reconstruction requirements. The honeycomb node stabilization zone 7 and the honeycomb node contact reinforcement zone are staggered, which can effectively disperse the support at the required support position, so that the force is more uniform and the support reinforcement is more stable.

[0048] In addition, six triangular areas 8 are formed between the honeycomb node stabilization area 7 and the honeycomb node contact reinforcement area, which enables the honeycomb node stabilization area 7 and the honeycomb node contact reinforcement area to work together to support the roof, effectively improving the stability of the square steel rod 23 on the mounting plate 2, which is beneficial for the node to continuously and effectively support the roof.

[0049] The hexagonal sleeve 21 has slots 22 on its edges, a connector 24 is fixedly connected to one end of the square steel rod 23 away from the first fixing plate 261, a first mounting seat 25 is rotatably connected to the connector 24, and a foot plate 251 on the first mounting seat 25 is inserted into the hexagonal sleeve 21 through the slot 22; it also includes a sleeve 27 rotatably connected to a threaded sleeve 271, one end of a screw rod 272 is rotatably connected to the square steel rod 23, the screw rod 272 extends into the sleeve 27 and is threadably connected to the threaded sleeve 271, and a plurality of second mounting seats 28 are respectively installed on the mounting plate 2, and one end of the sleeve 27 is rotatably connected to the second mounting seat 28 through a pin 281;
