Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a detachable support platform for the construction of the upper steel-concrete structure of a large silo. Background Technology

[0002] Construction of the upper steel-concrete structure of the large sintering silo (i.e.) Figure 1 The concrete structure platform (FL+20.50m) requires the erection of full-span scaffolding inside the silo, exceeding 8m in height, according to traditional methods. This constitutes a high-risk sub-project exceeding a certain scale, posing safety risks. Furthermore, the scaffolding erected on the inner wall of the silo is not vertically supported, which also presents safety hazards. In addition, the scaffolding can only be dismantled after the upper concrete structure of the silo has been completed and has reached the design strength requirements. During this period, other construction processes inside the silo cannot be carried out, resulting in a long overall construction period. Utility Model Content

[0003] The main objective of this invention is to propose a detachable support platform for the construction of the upper steel-concrete structure of a large silo, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A detachable support platform for the construction of the upper reinforced concrete structure of a large silo is installed on the inner top of the silo.

[0006] The detachable support platform includes several horizontal main beams and longitudinal secondary beams arranged at equal intervals. Both ends of the horizontal main beams and longitudinal main beams are connected to the inner wall of the silo through a first connecting plate. The first connecting plate is welded and fixed to the inner wall of the silo. The first connecting plate is detachably connected to the horizontal main beams and longitudinal secondary beams through a first bolt.

[0007] The longitudinal secondary beam includes several second connecting plates and several short secondary beams, wherein two second connecting plates are a pair and are welded and fixed to both sides of the transverse main beam respectively. The two second connecting plates between two adjacent transverse main beams are connected by short secondary beams, and both ends of the short secondary beams are detachably connected to the two second connecting plates by second bolts.

[0008] Preferably, the transverse main beam and the short secondary beam are channel steel.

[0009] Preferably, the first connecting plate and the second connecting plate are steel plates with a thickness of not less than 12mm.

[0010] Preferably, the transverse main beam is aligned with the direction of the reinforced concrete structure and is arranged vertically in parallel.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Reference Figure 1 This utility model is used to realize the construction of the upper steel-concrete structure 200 of the silo 100. The steel-concrete structure platform is located at FL+20.50m and is used to install equipment.

[0024] This utility model provides a detachable support platform 1 for the construction of the upper steel-concrete structure of a large silo. It is installed on the inner top of the silo 100, specifically at FL+19.40m. The concrete formwork support of the steel-concrete structure 200 is erected at a height of only 1.1m.

[0025] Reference Figure 2 , Figure 3The detachable support platform 1 includes several horizontal main beams 11 and longitudinal secondary beams 12 arranged at equal intervals to provide high-strength support. Both ends of the horizontal main beams 11 and the longitudinal main beams are connected to the inner wall of the silo 100 through a first connecting plate 13. The first connecting plate 13 is welded and fixed to the inner wall of the silo 100. The first connecting plate 13 is detachably connected to the horizontal main beams 11 and the longitudinal secondary beams 12 through a first bolt 14. The horizontal main beams 11 and the longitudinal secondary beams 12 are easy to disassemble. When the detachable support platform 1 is dismantled, the first connecting plate 13 can be permanently retained without removal and will not affect the normal use of the silo 100.

[0026] Reference Figure 2 , Figure 4 The longitudinal secondary beam 12 includes several second connecting plates 121 and several short secondary beams 122. Two second connecting plates 121 form a pair and are welded and fixed to both sides of the transverse main beam 11. Two second connecting plates 121 between two adjacent transverse main beams 11 are connected by short secondary beams 122. Both ends of the short secondary beams 122 are detachably connected to the two second connecting plates 121 by second bolts 123. The longitudinal secondary beam 12 is divided into several second connecting plates 121 and several short secondary beams 122. This facilitates disassembly and ensures that the transverse main beam 11 and the longitudinal secondary beam 12 are on the same plane, thus ensuring the level of the support platform. When disassembling the detachable support platform 1, the longitudinal secondary beams 12 are removed first, and then the transverse main beams 11 are removed.

[0027] The detachable support platform 1 of this utility model is installed on the inner top of the silo 100, eliminating the need to erect full-span scaffolding inside the silo 100, thus ensuring high safety. After the support platform is assembled and connected and fixed to the silo wall of the silo 100, the construction of the upper concrete formwork support project can be carried out using the platform. Furthermore, during the curing period of the upper concrete structure, other construction processes inside the silo 100 can proceed normally, greatly shortening the overall construction period. The dismantled support platform can be reused, saving construction costs.

[0028] As a preferred embodiment, the transverse main beam 11 and the short secondary beam 122 are channel steel, specifically C20A channel steel.

[0029] As a preferred embodiment, the first connecting plate 13 and the second connecting plate 121 are steel plates with a thickness of not less than 12mm. The width of the steel plate corresponds to the width of the channel steel. When connected to the channel steel, the steel plate is placed inside the channel steel and connected by two bolts, M12 bolts. Corresponding connection holes are provided on both the steel plate and the channel steel.

[0030] In a preferred embodiment, the transverse main beam 11 is aligned with the direction of the reinforced concrete structure 200 and is arranged vertically parallel to each other.

[0031] As a preferred embodiment, each transverse main beam 11 and short secondary beam 122 is marked with its length dimension and position number, and the numbering matches the installation sequence. The double marking enables the rapid installation of the transverse main beam 11 and short secondary beam 122, improves installation efficiency, and reduces the construction error rate.

[0032] As a preferred embodiment, the first connecting plate 13 is an L-shaped steel plate, which enhances bending resistance by utilizing the corner. Its vertical plate is welded to the inner wall of the silo 100, and the horizontal plate has at least two bolt holes. The horizontal main beam 11 or the longitudinal secondary beam 12 is embedded in the L-shaped corner and locked by the first bolt 14.

[0033] As a preferred embodiment, two short secondary beams 122 that are adjacent in the middle of the detachable support platform 1 in the lateral direction and have the same height are detachably connected by an X-shaped cross brace to improve the overall strength of the detachable support platform 1.

[0034] As a preferred embodiment, when the height of the detachable support platform 1 from the top of the silo 100 is small, protective railings can be installed around the perimeter of the detachable support platform 1. The bottom of the uprights of the protective railings are connected to the ends of the transverse main beam 11 and the longitudinal secondary beam 12 by pins or bolts. The safety of construction can be improved by installing protective railings.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
