Technical Field

[0001] This invention belongs to the field of building construction technology, specifically, it relates to a telescopic I-beam device applied to a circular track, used to adjust the distance between the curtain wall circular track and the edge of the structure, facilitating the hoisting of unit panels. Background Technology

[0002] With the continuous development of modern buildings, more and more novel, complex, and unique architectural forms have emerged, such as hyperboloid sail-shaped buildings, whose shapes are generally expressed through the curtain wall form of the building facade. However, using traditional I-beams for curtain wall circular tracks requires manual movement and fixing of the steel beam structure, adjusting the distance and curvature of the circular track from the wall structure on the outside of the floor slab. This adjustment is complex and difficult to meet the hoisting requirements of unit panels in complex, curved structures. It requires multiple segmented hoisting operations using circular tracks, making construction difficult and increasing the construction period and cost. Summary of the Invention

[0003] The purpose of this invention is to provide a telescopic I-beam device for use in curtain wall circular tracks. By adjusting the telescopic I-beam device, the distance between the circular track and the edge of the building structure can be adjusted, which facilitates the hoisting of unit panels.

[0004] To achieve the above objectives, the present invention provides a retractable I-beam beam device for a curtain wall circular track, comprising a steel beam structure, a supporting slide rail device, a telescopic drive device, and an I-beam circular track. The supporting slide rail device is detachably fixed to the building floor slab. The steel beam structure is mounted on the supporting slide rail device, with one end of the steel beam structure located inside the floor slab and the other end connected to the I-beam circular track located outside the floor slab. One end of the telescopic drive device is fixed to the supporting slide rail device, and the other end is connected to the steel beam structure. By driving the steel beam structure to extend and retract relative to the floor slab through the telescopic drive device, the I-beam circular track can be extended and retracted.

Rollers are arranged on opposite sides of the support blocks, and pressure rollers are arranged on opposite sides of the top of the support seats. One end of the telescopic drive device is fixed on the support seat.

[0008] Preferably, the telescopic drive device includes a screw support seat, a nut block, and a screw. The screw support seat is fixedly mounted on the support seat. The opposite sides of the nut block are fixedly connected to the support beam via connectors. One end of the screw is rotatably connected to the screw support seat, and the other end passes through the nut block in a threaded manner. When the screw rotates, it can drive the nut block to extend or retract the support beam relative to the floor slab.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention provides a retractable I-beam device for use in curtain wall circular tracks, such as... Figure 1 and Figure 2 As shown, it includes a steel beam structure, a supporting slide rail device, a telescopic drive device, and an I-beam circular track, wherein:

[0021] The steel beam structure includes two parallel, spaced-apart supporting steel beams 101, each of which is an I-beam. The two supporting steel beams 101 are connected and fixed by connectors, forming a gap between them. The two supporting steel beams 101 are parallel to the floor slab, and the front ends of the supporting steel beams 101 extend beyond the floor slab, located on the outer side of the floor slab.

[0022] In the gap between two supporting steel beams 101, several support blocks 102 and support seats 104 are placed at intervals along the length of the supporting steel beams. Rotatable rollers 103 are connected to both sides of each support block, and the two supporting steel beams 101 are placed on the rollers 103 located on both sides of the support block 102. The support seat 104 is fixed to the floor slab A by through-wall bolts. Rotatable pressure rollers 105 are respectively provided on both sides of the top of the support seat 104, located above the supporting steel beams 101, and each pressure roller 105 on both sides of the support seat 104 presses against one supporting steel beam 101. The rollers 103, support blocks 102, pressure rollers 105, and support seats 104 form a support slide rail device, providing support for the supporting steel beams 101 and allowing the supporting steel beams to move along the rollers 103 and pressure rollers 105, reducing friction during movement.

[0023] The telescopic drive device includes a nut block 201, a screw support seat 202, and a screw 203. The screw support seat 202 is fixedly mounted on the rear side of the support seat 104. The nut block 201 is located in the gap between the two supporting steel beams 101 at one end (i.e., the rear end) on the inner side of the floor slab. Both sides of the nut block 201 are connected and fixed to the supporting steel beams 101 on both sides via connecting rods. One end of the screw 203 is rotatably connected to the screw support seat 202. After passing through the nut block 201, the free end of the screw 203 is located outside the rear end of the supporting steel beam 101, that is, the screw 203 extends beyond the rear end of the supporting steel beam 101. A handle is provided on the free end of the lead screw 203. Rotating the lead screw 203 via the handle causes it to rotate relative to the lead screw support 202. When the lead screw 203 rotates, it drives the nut block 201 to make a linear displacement along the lead screw 203, thereby driving the support beam 101 to make a linear displacement relative to the floor slab, causing the front end of the support beam 101 to extend or retract relative to the floor slab. The threads on both sides of the lead screw 203 are arranged in opposite directions from its length center, which helps to limit the displacement distance of the support beam when the lead screw 203 rotates.

[0024] A steel plate 4 is fixedly welded to the lower front end of the steel beam 101, and four elongated bolt holes are provided in the middle of the steel plate 4.

[0025] A steel plate 4 is fixedly welded onto the I-beam ring track 6 on the outside of the wall structure, and four elongated bolt holes are provided in the middle of the steel plate 4.

[0026] During operation, first rotate the handle to make the nut block move linearly along the lead screw, driving the support beam to move along the rollers towards the outside of the floor slab, so that the front end of the support beam is positioned on the I-beam circular track 6. At this time, the oblong bolt holes on the steel plate 4 of the support beam are perpendicular to the oblong bolt holes on the I-beam circular track 6. Then, multiple bolts are passed through the oblong bolt holes on the steel plate of the support beam and the oblong bolt holes on the steel plate of the I-beam circular track 6, respectively, and the support beam 101 is fixedly connected to the I-beam circular track 6 by the bolt group formed by the multiple bolts. The oblong bolt holes facilitate fine adjustment of the front end of the support beam and the I-beam circular track in terms of front-back, left-right, and right positions.

[0027] Then, the telescopic drive device drives the supporting steel beams, along with the I-beam ring track 6, to shift relative to the floor slab, adjusting the distance between the I-beam ring track 6 and the wall structure to position it appropriately for hoisting. After adjusting the position, fasteners are placed on top of the two supporting steel beams, and then the through-wall bolts 3 are passed through the fasteners and floor slab A to fix the supporting steel beams to floor slab A.

[0028] Then, through-wall bolts 3 are installed and fixed between the connectors and the floor slab between the two supporting steel beams 101. One end of the through-wall bolt 3 is located above the connector, and the other end passes through the floor slab and is located below the floor slab. The through-wall bolt 3 is in a pre-tightened state, and the supporting steel beams 101 are initially fixed.

[0029] The aforementioned retractable I-beam device is installed at the required floor intervals and connected to the circular track on the outside of the building wall. By adjusting the position of the supporting steel beams in sections, the entire circular track can be displaced relative to the floor slab to adapt to complex, curved building structures, facilitate the hoisting of unit panels, and make construction convenient.
