Abstract
The utility model relates to a steel supporting platform for the sectional hoisting of a long-span special triangular truss, which comprises a concrete grandstand, and is characterized in that the post top of the concrete grandstand is embedded with steel embedded parts in advance, and is provided with four counterforce supporting points; a steel pipe support adjusts the height difference of the four counterforce supporting points on the post top of the concrete grandstand, and a bottom frame is formed by utilizing a box girder. The steel supporting platform is characterized in that the bottom frame supporting legs and the steel embedded parts at the concrete grandstand post top are in around welding, the height of the welding line is 12mm, the steel pipe support and box girder and the like are in strong around welding, and the height of the welding line is 12mm. The steel supporting platform has the advantages that since the post top in the concrete grandstand area is provided with a corresponding transition bearing steel platform, a lattice supporting system is further arranged on the transition bearing steel platform, and finally, the curvature effect that the whole truss after being unfolded is consistent with the ideal design can be ensured.
Description
Technical field
The utility model relates to a kind of steel platform that supports when being used for the special-shaped English truss segmental hoisting of large span.
Background technology
In the large space steel work, the utilization large span steel truss is chosen empty design.In selecting, construction technical schemes considers that lifting machine performance, construction cost, construction are simple and direct, large-span truss is carried out equitable subsection, and steel is set in the end of segmentation truss supports, steel is supported under the prerequisite of the requirement of guaranteeing homeostasis and intensity, the segmentation truss is carried out stable support, general now the employing expired hall pin hand, but running into to require to carry out being provided with of full hall pin hand according to the Support Position time, when installing, will run into above-mentioned situation as the segmentation truss that carries out large span steel truss on the stadium of having built up concrete structure at one.Because concrete grandstand beam, plate bearing capacity do not satisfy the requirement of shelving of steel support, as adopt full hall pin hand, its pin hand workload, construction period, difficulty of construction do not satisfy the needs of site operation fully.Support when therefore demanding urgently adopting new job practices and corresponding braced structures to satisfy the segmentation truss installation of on the stadium of building up concrete structure, carrying out large span steel truss.
Summary of the invention
The purpose of this utility model is existingly when solving in the prior art segmentation truss that carries out large span steel truss on a stadium of having built up concrete structure and installing can't carry out the problem that full hall pin hand supports, and a kind of steel platform that supports when being used for the special-shaped English truss segmental hoisting of large span is provided.The utility model design is a kind of supports the steel platform when being used for the special-shaped English truss segmental hoisting of large span, comprise the concrete grandstand, it is characterized in that: on concrete grandstand capital, be embedded with the steel embedded part in advance, four counter-force fulcrums are set, the discrepancy in elevation with four counter-force fulcrums on the steel pipe supporting handle concrete grandstand capital is carried out leveling, and utilizes the case beam to form a underframe.It is characterized in that: weldering around the steel embedded part of burying underground in advance on underframe supporting leg and the concrete grandstand capital, weld bead height 12mm, weldering around steel pipe support and case beam etc. are strong, weld bead height 12mm.The utility model has the advantages that the capital place that utilizes former concrete grandstand zone is provided with corresponding conversion load-bearing steel platform, conveniently on conversion load-bearing steel platform, the lattice support system is set again, guarantees that finally the whole Pin of truss closes up back and the corresponding to curvature effect of design ideal.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, Fig. 2 base frame construction schematic diagram of the present utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment:
Comprise concrete grandstand 1 among the figure, it is characterized in that: on concrete grandstand capital, be embedded with steel embedded part 2 in advance, four counter-force fulcrums 3 are set, carry out leveling, and utilize the case beam to form a underframe 4 with the discrepancy in elevation of four counter-force fulcrums on the steel pipe supporting handle concrete grandstand capital.It is characterized in that: weldering around the steel embedded part of burying underground in advance on underframe supporting leg and the concrete grandstand capital, weld bead height 12mm, weldering around steel pipe support and case beam etc. are strong, weld bead height 12mm.
During practice of construction, on the capital of the concrete grandstand of projection place of the segmentation truss that needs accordingly to install large span steel truss, bury the steel embedded part in advance underground, and four counter-force fulcrums are set, because general one-tenth ladder on the grandstand, therefore there is difference in height between four counter-force fulcrums, utilize steel pipe to support difference in height is carried out leveling, and then utilize the case beam to form a underframe, thereby form a load-bearing steel platform, when lifting segmentation truss, can on load-bearing steel platform, the lattice support system be set easily again, guarantee that finally the whole Pin of truss closes up back and the corresponding to curvature effect of design ideal.
