Description

Technical Field

[0001] The utility model relates to the technical field of suspended basket construction, in particular to a telescopic leg applicable to a special-shaped suspended basket. Background Art

[0002] A special-shaped suspended basket is a modern building construction equipment, usually used for the exterior wall maintenance and decoration of high-rise buildings.

[0003] The front and rear legs (or called front and rear brackets) of a traditional ordinary suspended basket adopt a wide support bottom plate at the bottom. During operation, the support bottom plate directly supports on the working surface. For example, in the attached drawing of the Chinese patent "A movable device for a construction suspended basket bracket without unloading" with the publication number CN218323823U, the cross-sectional area of the suspended basket bottom plate 31 is much larger than the area of the telescopic column 32 of the suspended basket. During operation, the suspended basket bottom plate 31 directly supports on the working plane, and its specific implementation method records "the bracket steel wheels 33 under the suspended basket bottom plate 31", "the bracket steel wheels can be made into universal wheel forms for easy movement in all directions". This bracket structure occupies a large area and is difficult to install in places with a relatively narrow construction environment. Moreover, during the construction process, although a counterweight 7 is provided on the counterweight bracket 2, there are no other fixing measures for the suspended basket bottom plate 31. When affected by strong winds or other external forces, the suspended basket bottom plate 31 may still displace, resulting in danger. The structural form of the traditional ordinary suspended basket is not suitable for the use environment of the special-shaped suspended basket; in addition, from the content recorded in the attached drawing of this patent, its hanging frame 1 directly penetrates through the telescopic column 32 of the suspended basket, and the counterweight telescopic column 22 is directly fixed to the hanging frame 1. This connection method will weaken the structural strength of the counterweight telescopic column 22 and reduce the reliability of the connection; in addition, according to the record in the 43rd paragraph of the Chinese patent "A hanging mechanism for a curtain wall suspended basket" with the publication number CN220319073U, "a channel steel 120 is arranged at the bottom of the upper column 110, and the channel steel 120 is arranged in a U shape... so that the first connecting square pipe 40 is placed in the channel steel 120... thereby ensuring the connectivity and supportability of the front beam 21 and the middle beam 22". It can be seen that it uses a connecting square pipe and a channel steel 120 with a U-shaped structure as fixed structural members to fix the front beam 21 and the middle beam 22 on the upper column 110. Although this connection method can avoid the problem of weakening the strength of the upper column 110 (equivalent to a bracket or called a leg), the structure of this connection method is still relatively complex. The problems of large floor area of the bracket structure, weakening of the leg strength, and complex fixing structure existing in the above traditional suspended baskets need to be solved in the special-shaped suspended basket. Summary of the Utility Model

[0004] In view of this, the present utility model provides a telescopic leg applicable to a special-shaped hanging basket. The bottom of the telescopic leg is fixed to the working plane, and the top of the telescopic leg is fixedly connected to the cross bar of the hanging basket through a U-shaped frame. The structure is simple and reliable, and it can be applied to the construction environment of various special-shaped hanging baskets.

[0005] The cross bar of the special-shaped hanging basket is supported by the telescopic leg. The telescopic leg includes a telescopic support member, and the telescopic support member includes a main support member and a sub-support member.

[0006] A bottom pressing plate is fixedly arranged at the bottom of the main support member. Installation holes are provided on the bottom pressing plate, and the bottom pressing plate is fixedly connected to the working surface through fasteners passing through the installation holes.

[0007] The sub-support member is sleeved along the axial direction of the main support member for adjusting the height of the leg. A U-shaped frame is fixedly arranged at the top of the sub-support member.

[0008] The cross bar of the hanging basket is fixedly installed on the sub-support member through the U-shaped frame, and the two side plates of the U-shaped frame limit the cross bar of the hanging basket.

[0009] Preferably, a plurality of upper rib plates are uniformly arranged on the outer peripheral wall of the top of the sub-support member, and the upper rib plates fixedly connect the U-shaped frame and the sub-support member.

[0010] Preferably, a plurality of lower rib plates are uniformly arranged on the outer peripheral wall of the bottom of the main support member, and the lower rib plates fixedly connect the bottom pressing plate and the main support member.

[0011] Preferably, force sensors are arranged on the support plates of the U-shaped frame and the fasteners.

[0012] Preferably, the fastener is an expansion bolt.

[0013] Preferably, both the main support member and the sub-support member are made of square steel.

[0014] Preferably, a plurality of main limit through holes are arranged on the side wall of the main support member perpendicular to the axis direction, and a plurality of sub-limit through holes are arranged at corresponding positions on the side wall of the sub-support member corresponding to the plurality of main limit through holes.

[0015] A fixing pin passes through the main limit through hole and the sub-limit through hole to limit the main support member and the sub-support member.

[0016] Beneficial effects

[0017] (1) The special-shaped hanging basket leg of the present utility model includes a telescopic support member. By sleeving a secondary support member capable of moving axially along the main support member above the main support member, the adjustment of the length of the hanging basket leg can be achieved. At the same time, the U-shaped frame of the present utility model makes the connection structure between the leg and the hanging basket crossbar simple and reliable, and does not weaken the strength of the telescopic support member. Furthermore, the structure in which the telescopic support member is fixedly connected to the working surface through the bottom pressing plate not only increases the connection strength between the telescopic support member and the working surface, but also avoids setting a wide bottom plate at the bottom of the telescopic support member, solving the problem that the area of the hanging basket bottom plate at the bottom of the front and rear legs of the traditional hanging basket is large and cannot be set in a narrow space (such as the parapet of a sloping roof). At the same time, it increases the anti-slip, anti-shear and anti-overturning capabilities of the telescopic legs of the special-shaped hanging basket.

[0018] (2) The two side plates of the U-shaped frame of the present utility model limit the hanging basket crossbar laterally. By opening installation holes at the corresponding positions on the two side plates and the side wall of the hanging basket crossbar, and combining fasteners to fix the crossbar and the U-shaped frame together. On this basis, ribbed plates are provided between the top of the telescopic support member and the U-shaped frame and between the bottom of the telescopic support member and the bottom pressing plate, further improving the support strength of the telescopic leg anchoring device, enhancing the overall stability of the special-shaped hanging basket, effectively preventing the hanging basket from tipping laterally, and ensuring construction safety.

[0019] (3) Force sensors are provided on the support plates and fasteners of the U-shaped frame to monitor the forces on the support plates and fasteners of the U-shaped frame in real time, avoiding the tipping of the hanging basket crossbar due to excessive forces on the support plates and fasteners of the U-shaped frame.

[0020] (4) The main support member and the secondary support member of the present utility model can be processed from square steel, which is convenient for obtaining materials locally, and the processing and production are simple and fast, and it is easy to promote.

[0021] (5) Except for the expansion bolts, other components of the present utility model can be recycled, which is energy-saving and environmentally friendly and meets the elements of a green and civilized construction site. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, content and advantages of the present utility model clearer, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model.

[0031] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, left, right" usually refer to the upper, lower, left, right shown in the reference drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself. The following will detail the present utility model with reference to the drawings and embodiments.

[0032] Such as Figure 1-7As shown in the figure, a telescopic leg applicable to a special-shaped hanging basket. The crossbar 8 of the special-shaped hanging basket is supported by the telescopic leg. The telescopic leg includes a telescopic support member, and the telescopic support member includes a main support member 4 and a secondary support member 3 sleeved above it that can move along the axial direction of the main support member 4. The secondary support member 3 extends out from above the main support member 4. Through the axial telescopic movement between the main support member 4 and the secondary support member 3, the length of the leg changes, that is, the height of the crossbar of the special-shaped hanging basket can be adjusted. A number of main limit through holes are provided on the side wall of the main support member 4 perpendicular to the axis direction. A number of secondary limit through holes are provided at positions corresponding to the main limit through holes on the side wall of the secondary support member 3. The main limit through holes and the secondary limit through holes correspond one by one, the main limit through holes and the secondary limit through holes are coaxial, and a fixing pin 5 can pass through the main limit through hole and the secondary limit through hole to limit the main support member 4 and the secondary support member 3. The pin shaft of the fixing pin 5 has an external thread. After the pin shaft passes through the main limit through hole and the secondary limit through hole, it is fastened by a nut to improve the fastening degree between the main support member 4 and the secondary support member 3. Moreover, a U-shaped frame 1 is provided above the secondary support member 3. The crossbar 8 of the hanging basket passes through the U-shaped frame 1, and the two side plates of the U-shaped frame 1 clamp the crossbar 8 to axially limit the crossbar 8. A bottom pressing plate 6 is provided between the bottom surface of the main support member 4 and the working surface 9 (including the concrete structure surface). The bottom pressing plate 6 is rectangular, and installation holes are provided at its four corners. The bottom pressing plate 6 is welded to the bottom of the main support member 4, and the bottom pressing plate 6 is anchored to the working surface 9 through fasteners 7 passing through the installation holes.

[0033] Because the telescopic leg can be directly fixed on the working surface without setting a wide support bottom plate at the bottom of the telescopic leg, it can be adapted to the construction of building surfaces with special shapes or structures, such as curved surfaces, inclined surfaces or irregularly shaped buildings, solving the technical problem that the hanging basket legs cannot be set on unconventional working surfaces, meeting the construction environment requirements of special-shaped hanging baskets. At the same time, it increases the anti-slip, anti-shear and anti-overturning capabilities of the telescopic legs of the special-shaped hanging basket.

[0034] Moreover, a number of upper end rib plates 2 are evenly provided on the outer peripheral wall of the top of the secondary support member 3. The upper end rib plates 2 fixedly connect the U-shaped frame 1 and the secondary support member 3. Two through holes that can accommodate bolts of A20 specification are provided on each support plate of the U-shaped frame 1. The through holes are adapted to the installation holes on the side wall of the crossbar 8 of the hanging basket. A number of lower end rib plates 10 are evenly provided on the outer peripheral wall of the bottom of the main support member 4. The shape of the lower end rib plates 10 is a right triangle, and the two right sides are respectively fixedly connected to the top surface of the bottom pressing plate 6 and the side wall of the main support member 4. In this embodiment, the lower end rib plates 10 are welded to both the main support member 4 and the bottom pressing plate 6. The setting of the upper end rib plates 2 improves the stability of the connection between the crossbar 8 of the hanging basket and the telescopic leg, and the setting of the lower end rib plates 10 improves the stability of the connection between the telescopic leg and the working plane.

[0035] Specifically, force sensors (not shown in the drawings) are provided on the support plate of the U-shaped frame 1 and the fastener 7 to monitor the forces on the support plate of the U-shaped frame 1 and the fastener in real time, so as to avoid the tipping of the hanging basket cross bar 8 due to excessive forces on the support plate of the U-shaped frame 1 and the fastener 7, and further improve the safety and reliability.

[0036] As an example, since there are several main limit through holes and secondary limit through holes, the length by which the secondary support member 3 extends from the main support member 4 can be adjusted.

[0037] As an example, the main support member 4 is a 200*200*2 square steel with a length of 550 cm; the secondary support member 3 is a 180*180*2 square steel with a length of 550 cm.

[0038] As an example, there are 3 main limit through holes provided on the main support member 4, with a spacing of 200 mm between each main limit through hole. The top main limit through hole is 50 mm away from the top end face of the main limit member 4, and the bottom main limit through hole is 100 mm away from the bottom end face of the main limit member 4.

[0039] As an example, there are 3 secondary limit through holes provided on the secondary support member 3, with a spacing of 200 mm between each secondary limit through hole. The top secondary limit through hole is 100 mm away from the top end face of the secondary limit member 3, and the bottom secondary limit through hole is 50 mm away from the bottom end face of the secondary limit member 3.

[0040] The fixing pin is an A20 anchor bolt, and the fastener 7 is an expansion bolt.

[0041] As an example, there are four upper rib plates 2. The outer shape of the upper rib plate 2 is a right triangle, and the two right sides are respectively connected to the bottom of the U-shaped frame 1 and the side wall of the secondary support member 3;

[0042] The upper rib plate 2 is a galvanized steel with a width of 100 mm and a thickness of 10 mm.

[0043] The U-shaped frame 1 is processed from a steel plate with a width of 100 mm, a height of 100, and a thickness of 10 mm.

[0044] As an example, the upper rib plate 2 is connected to the U-shaped frame 1 and the secondary support member 3 by welding processes.

[0045] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
