Abstract

The application provides a cantilever unloading platform, and relates to the field of house building engineering. The cantilever unloading platform comprises an unloading platform body and an unloading platform channel. The unloading platform body is used for loading and unloading building materials. The unloading platform channel is used as a channel for conveying building materials and comprises an I-shaped steel, a concave square steel, a vertical supporting square steel, a horizontal supporting square steel and a wooden formwork. Two I-shaped steels are arranged in parallel and at intervals. A plurality of concave square steels are arranged on the web of each I-shaped steel. The two ends of the horizontal supporting square steel are respectively arranged between the limiting grooves of the corresponding two concave square steels on the adjacent two I-shaped steels. A plurality of vertical supporting square steels are arranged on the inner side wall of the web of each I-shaped steel and are located at the bottom of the limiting groove on each concave square steel. The wooden formwork is arranged on the plurality of horizontal supporting square steels. The structure can effectively avoid the problem that the I-shaped steel used as a main beam has a steel pipe head residual and cannot be welded again due to the need to disassemble the unloading platform and cut the steel pipe in the later stage.

Description

Technical Field

[0001] This application relates to the field of building construction engineering, and in particular to a cantilevered unloading platform. Background Technology

[0002] The passage between the secondary beam of the unloading platform and the main floor of the building is usually made of steel pipes welded to I-beams. Over time, the steel pipes may deform and deflect excessively, posing a safety hazard. Moreover, when dismantling the unloading platform, the steel pipes need to be cut, which will directly result in steel pipe ends remaining on the I-beams of the main beam, making it impossible to weld the steel pipes of the next unloading platform a second time.

[0003] Therefore, there is a need for an easily obtainable and readily implementable device to improve the access of the cantilevered unloading platform. Utility Model Content

[0004] One of the purposes of this application is to provide a cantilevered unloading platform, which aims to solve the problem that the long-term use of steel pipes in the passage structure between the secondary beam of the existing unloading platform and the main floor of the building can lead to significant safety hazards.

[0005] The technical solution of this application is:

[0006] A cantilevered unloading platform includes an unloading platform body and an unloading platform channel; the unloading platform body is used for loading and unloading building materials dismantled from the main floor of a building; the unloading platform channel is located between the unloading platform body and the main floor of the building and serves as a channel for transporting the building materials, and includes I-beams, concave square steel, vertical support square steel, horizontal support square steel, and wooden formwork;

[0007] Two H-beams are arranged in parallel and spaced apart; multiple concave square steel bars are provided on one inner side wall of the web of each H-beam; the two ends of the transverse support square steel bars are respectively placed between the limiting grooves of two corresponding concave square steel bars on two adjacent H-beams; multiple vertical support square steel bars are respectively arranged on one inner side wall of the web of each H-beam and are located at the bottom of the limiting groove on each concave square steel bar; the wooden template is arranged on the multiple transverse support square steel bars.

[0008] As one technical solution of this application, multiple concave square steels on each I-beam are connected in sequence and arranged along the length of the I-beam.

[0009] As one technical solution of this application, the multiple concave square steels on each I-beam are all on the same straight line and have the same installation height.

[0010] As one technical solution of this application, the multiple vertical support square steels on each I-beam are arranged parallel to each other along the height direction of the I-beam and are all located directly below the corresponding concave square steel.

[0011] As one technical solution of this application, the concave square steel and the vertical support square steel are respectively welded to the web of the I-beam.

[0012] As one technical solution of this application, the transverse support square steels are arranged horizontally at parallel intervals.

[0013] As one technical solution of this application, the I-beam is an 18# I-beam; the thickness of the wooden template is 14mm; the square steel dimensions of the concave square steel, the vertical support square steel, and the horizontal support square steel are all 100mm×50mm×3mm; and the dimensions of the limiting groove are 100mm×50mm.

[0014] As one technical solution of this application, the bottom of the vertical support square steel extends to the inner lower flange of the I-beam, the top extends to the bottom of the limiting groove, and the side surface is welded to the inner web of the I-beam.

[0015] As one technical solution of this application, the distance between the concave square steel and the inner upper flange of the I-beam is 50mm.

[0016] The beneficial effects of this application are:

[0017] This application provides a cantilevered unloading platform. The structure involves pre-welding concave square steel and vertical support square steel to the inner side of the webs of two I-beams used as main beams. Then, the transverse support square steel for supporting wooden formwork is placed in the grooves of the concave square steel. Finally, the wooden formwork is placed into the gap between the concave square steel and the I-beams. This effectively solves the problem of excessive deformation and deflection of steel pipes in the passageway structure between the secondary beams of the unloading platform and the main building floor, which can lead to safety hazards due to long-term use. Furthermore, the transverse support square steel only needs to be installed and disassembled, and can be recycled. This avoids the problem of needing to cut steel pipes when dismantling the unloading platform later, resulting in residual steel pipe ends on the I-beams used as main beams that cannot be welded again.

[0030] Example:

[0031] Please refer to Figure 1 (Refer to) Figures 2 to 3This application provides a cantilevered unloading platform, which includes an unloading platform body 2 and an unloading platform channel 3. The unloading platform body 2 is used for loading and unloading building materials dismantled from the main floor 1 of a building. The unloading platform channel 3 is located between the unloading platform body 2 and the main floor 1 of the building and serves as a channel for transporting building materials. Further, the unloading platform channel 3 mainly includes H-beams 4, concave square steel 5, vertical support square steel 6, horizontal support square steel 7, and wooden formwork 8. Two H-beams 4 are arranged parallel and spaced apart. Simultaneously, multiple concave square steel 5 are provided on one inner side wall of the web of each H-beam 4, and the multiple concave square steel 5 on each H-beam 4 are connected sequentially and arranged along the length of the H-beam 4. The multiple concave square steel 5 on each H-beam 4 are all on the same straight line and have the same installation height. In addition, the horizontal support square steel 7... The two ends of the supporting square steel 7 are respectively placed between the limiting grooves of two corresponding concave square steels 5 on two adjacent I-beams 4; and multiple vertical supporting square steels 6 are respectively set on an inner side wall of the web of each I-beam 4, and at the bottom of the limiting groove on each concave square steel 5. The multiple vertical supporting square steels 6 on each I-beam 4 are arranged parallel to each other along the height direction of the I-beam 4, and are all directly below the corresponding concave square steel 5; the wooden formwork 8 is set on multiple horizontal supporting square steels 7.

[0032] It should be noted that the horizontal support square steel 7 is set horizontally with parallel intervals. At the same time, the concave square steel 5 and the vertical support square steel 6 are welded to the inner side of the web of the I-beam 4. The welding will not affect the rigidity and strength of the 18# I-beam 4 itself. After the horizontal support square steel 7 and the 14mm thick wooden template 8 are disassembled, the 18# I-beam 4 (3) of the cantilever unloading platform can still be used as a normal I-beam 4.

[0033] It should be noted that in this embodiment, the I-beam 4 is an 18# I-beam; the thickness of the wooden formwork 8 is 14mm. The 14mm thick wooden formwork 8 is inserted through the gap between the concave square steel 5 and the upper inner flange of the 18# I-beam 4, which facilitates the entry and exit of personnel and materials later, and also facilitates disassembly later; the dimensions of the concave square steel 5, the vertical support square steel 6, and the horizontal support square steel 7 are all 100mm×50mm×3mm. Square steel of this size has high rigidity and will not deform; the dimensions of the limiting groove are 100mm×50mm, which is just large enough to accommodate the horizontal support square steel 7.

[0034] It should be noted that, in this embodiment, the bottom of the vertical support square steel 6 extends to the inner lower flange of the I-beam 4, the top extends to the bottom of the limiting groove, and the side surface is welded to the inner web of the I-beam 4.

[0035] It should be noted that in this embodiment, the distance between the concave square steel 5 and the inner upper flange of the I-beam 4 is 50mm, which facilitates the insertion of the lateral support square steel 7 from the gap into the limiting groove of the concave square steel 5, and also facilitates disassembly later.

[0036] In summary, this application provides a cantilevered unloading platform. This structure involves pre-welding concave square steel 5 and vertical support square steel 6 to the inner sides of two I-beams 4 used as main beams. Then, the transverse support square steel 7, used to support the wooden formwork 8, is placed in the groove of the concave square steel 5. Finally, the wooden formwork 8 is placed into the gap between the concave square steel 5 and the I-beams 4. This effectively solves the problem of excessive deformation and deflection of the steel pipes in the passageway structure between the secondary beam of the unloading platform and the main floor 1 of the building, which could lead to safety hazards. Furthermore, the transverse support square steel 7 only needs to be installed and disassembled, and can be recycled. This avoids the problem of needing to cut steel pipes when disassembling the unloading platform later, resulting in residual steel pipe ends on the I-beams 4 used as main beams that cannot be welded again.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
