[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The high-stability support seat connected to a steel structure shown in the figure includes a support seat body 1, a lateral support frame 2 is welded and fixed on the outer surface of the support seat body 1, a bottom assembly frame 3 is fixedly installed on the lower end of the lateral support frame 2, an adjustable rubber extrusion pad 4 is bolted on the inner wall of the bottom assembly frame 3, and the lateral support frame 2 and the bottom assembly frame 3 are connected and limited by a split sliding guide rail 5.

[0029] Working principle: First, the longitudinally arranged steel sections are inserted and fixed inside the upper opening of the support base body 1, and then the lower steel sections are also inserted and fixed inside the lower opening of the support base body 1. A bottom assembly frame 3 is set on each steel section, which is fixed to the connecting end of the lateral support frame 2 through the adjacent bottom assembly frame 3. The installation method of the horizontal steel sections is also the same.

[0030] In order to cooperate with the screw adjustment, the split sliding guide rail 5 includes an adjustment guide rail 51 welded and fixed on the two side walls of the lateral support frame 2, an outer fixed frame 52 welded and fixed on the outer wall of the bottom assembly frame 3, an internal thread adjustment block 53 fixed on both sides of the outer fixed frame 52, and a horizontal adjustment screw 54 installed inside the adjustment guide rail 51.

[0031] Openings for assembling the transverse adjusting screw rod 54 are provided at both ends of the adjusting guide rail 51 , and external limiting covers are bolted to the outer opening positions of the openings to limit the assembly of the transverse adjusting screw rod 54 .

[0032] By rotating the transverse adjusting screw rod 54 , the internal thread adjusting block 53 is controlled to slide along the adjusting guide rail 51 , thereby changing the position between the lateral support frame 2 and the bottom assembly frame 3 .

[0033] In order to facilitate installation and telescopic adjustment, a strip-shaped telescopic groove 31 for installing the adjustable rubber extrusion pad 4 is opened on the inner side of the bottom assembly frame 3.

[0034] To facilitate extrusion adjustment, the adjustable rubber extrusion pad 4 includes a strip extrusion frame 41 slidably mounted inside the strip expansion slot 31, a rubber contact strip 42 fixed on the extrusion surface of the strip extrusion frame 41, a side guide rod 43 fixedly assembled in the middle position of the outer side of the strip extrusion frame 41, an extrusion spring 44 sleeved on the outer side of the side guide rod 43, and a locking bolt 45 threadedly assembled on the outer side of the bottom assembly frame 3.

[0035] The reaction force generated by the extrusion spring 44 squeezes the strip extrusion frame 41 to slide and adjust inside the strip telescopic slot 31, driving the strip extrusion frame 41 to drive the rubber extrusion strip 42 to squeeze and fix outside the beam.

[0036] In order to cooperate with end control, an external control head 55 is axially fixed to the end of the transverse adjustment screw rod 54.

[0037] The external control head 55 is controlled to rotate by an external tool, thereby rotating and adjusting the transverse adjustment screw rod 54 , and the internal thread adjustment block 53 is controlled to perform translation adjustment along the adjustment guide rail 51 by rotating the transverse adjustment screw rod 54 .

[0038] In order to monitor the pressure after assembly in real time, an annular pressure sensor 6 is fixedly mounted on the inner side of the strip-shaped expansion slot 31 , which is located on the extrusion surface of the extrusion spring 44 .

[0039] A reasonable pressure range will be set in advance. After assembly, the extrusion spring 44 will form an extrusion force on the annular pressure sensor 6. The pressure value is monitored by the annular pressure sensor 6. According to the value changes of the annular pressure sensor 6 at different positions, the direction of the steel section bending can be judged, thereby judging the type and location of the fault.

[0040] In order to improve the internal support, an embedded support rod 7 is fixedly mounted on the bottom end of the support seat body 1.

[0041] In order to cooperate with the bottom limit, a bottom side limit socket 8 is opened at the bottom end of the support seat body 1 to cooperate with the extended end of the embedded support rod 7.

[0042] When multiple steel sections are axially spliced, the protruding end of the embedded support rod 7 on one side is inserted into the bottom limit socket 8 on the opposite end steel section. This has the advantage of not only ensuring the supporting stability of the embedded support rod 7, but also facilitating extrusion.

[0043] The crossbeam passes through the bottom assembly frame 3 in the transverse direction, and a through hole is provided in the transverse interior thereof to match the bottom limiting insertion hole 8 for installation and limiting.

[0044] In order to cooperate with the assembly limit, the inner outer wall of the strip-shaped extrusion frame 41 is provided with a lateral protrusion 46 , and the inside of the lateral protrusion 46 is provided with an internal assembly tube 47 that passes through the rubber contact strip 42 .

[0045] The upper end of the rubber contact strip 42 has an integral limit strip protruding toward the inside of the lateral protrusion 46 , thereby ensuring the stability of the lateral installation limit of the rubber contact strip 42 at the bottom side of the strip-shaped extrusion frame 41 .

[0046] In order to cooperate with the lateral limiting capability of the assembly end, a strip-shaped limiting groove 9 that cooperates with the lateral support frame 2 is opened on the side wall of the bottom assembly frame 3.

[0047] The bottom assembly frame 3 is sleeved on the bottom end of the lateral support frame 2 through the strip-shaped limiting groove 9, thereby being plugged and limited with the lateral support frame 2.

[0048] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
