Abstract
The utility model discloses a steel-concrete girder fabricating pedestal with small independent concrete foundations, which comprises an end concrete foundation and a plurality of small independent concrete foundations which are distributed sequentially and linearly. Steel plate combining parts are embedded on each of the end concrete foundation and the small independent concrete foundations, each steel pipe upright column is connected to the steel plate combining parts of the corresponding small independent concrete foundation through bolts and is at the same level line with the steel plate combining parts of the end concrete foundation, a steelwork longitudinal beam is connected to the steel pipe upright columns through bolts, and a bottom die is paved on the steelwork longitudinal beam. The steel-concrete girder fabricating pedestal with the small independent concrete foundations has the advantages that template consumption is greatly reduced, fabrication procedures are greatly simplified by the aid of the splicing structural form, construction is quick and convenient and construction period is shortened effectively. Besides, the steelwork longitudinal beam and the steel pipe upright columns are reusable so that waste is avoided, and the steel-concrete girder fabricating pedestal is convenient in mounting and demounting by means of bolt connection.
Description
Technical field
The utility model relate to a kind ofly be applied in the railroad bridge engineering, for accomplishing the indispensable tooling device of prefabricated case beam, belong to the little concrete foundation steel reinforced concrete of a kind of independence beam making bench more specifically.
Background technology
For I, II, III level railway; Especially Line for Passenger Transportation circuit major part is made up of bridge; The case beam is the main part of bridge; The case beam is divided into cast-in-situ box girder and prefabricated case beam, and wherein the production of prefabricated case beam need be carried out centralized production by special beam making field, and beam making bench is the indispensable tooling device of beam making field.
At present, be applied in the beam making bench of railway box in beam prefabricated and be mainly the whole concrete structure, form by basis, end, end longeron, basis, middle part and waist longeron.In the construction, at first carry out foundation excavation and processing, tie up basis, end and middle part reinforcement foundation again; And the pre-buried muscle of longeron, formwork erection construction end and basis, middle part are tied up longeron poker muscle and pre-buried steel member again; Formwork erection carries out the longeron concrete construction again, and another kind of beam making bench structure is that top is steel design, but the middle part lower base still is a monoblock concrete foundation; There are following two kinds of structure problems in these two kinds of versions in practice of construction: first kind of structure: 1, to this whole concrete structure, work progress comprises: formwork erection, concrete construction, concrete curing, form removal etc., manufacturing process take a lot of work, time-consuming; Cycle is long, and colligation welding quantity is big; 2, the whole concrete structure not only can not reuse, and the later stage reclaims in place time dismounting man-hour is big, expense is high; 3, to adopt a large amount of templates in the construction, reinforcing bar and concrete, cost is high, and the consumption of mould material is big, and armored concrete expends many; Second kind of structure: 1, top be that steel construction but middle and lower part appoint so is a monoblock concrete foundation, and construction still need be used a large amount of concrete, causes a certain amount of waste; 2, the little concrete foundation steel reinforced concrete of a kind of independence beam making bench of the utility model is after the shortcoming of having avoided structure one; On the basis of structure two basis, middle and lower part is become the little concrete foundation of single independence again, realized maximized cost savings, used with turnover.
The utility model content
The purpose of the utility model provides the little concrete foundation steel reinforced concrete of a kind of independence beam making bench, gives up with simplification work progress, the raw-material consumption of minimizing.
The technical scheme of the utility model is following:
The little concrete foundation steel reinforced concrete of a kind of independence beam making bench; Include end concrete foundation, several independent little concrete foundations that straight line is successively arranged; Be embedded with the steel plate sub-assembly respectively on end concrete foundation, the independent little concrete foundation; Steel plate sub-assembly on the independent little concrete foundation is connected with steel pipe post through bolt; The steel plate sub-assembly of each steel pipe post and end concrete foundation is positioned on the same horizontal line, and is connected with the steel construction longeron through bolt, is equipped with bed die on the steel construction longeron.
Described steel construction longeron is three roads that laterally arrange.
The beneficial effect of the utility model is following:
The utility model is little concrete foundation steel and concrete structure independently, has significantly reduced the use amount of template, and the version of its assembly unit has been simplified production process greatly, and quick construction is convenient, effectively the reduction of erection time; Its steel construction longeron and steel pipe column can be reused, and have avoided waste; The type of attachment easy accessibility of its bolt; The utility model can be eliminated the construction error of pedestal well through the adjustment steel pipe column; The utility model has realized that through the basis, middle part all being changed to the little concrete foundation of single independence the concrete of the minimum of pedestal uses, and has realized maximized turnover; The spacing that can be through changing steel pipe post and the width of end template are effectively realized general between case beam that bottom width differs greatly, like single line case beam and double line box girder; The utility model is accomplished the prefabricated needs that the steel and concrete structure of assembling can satisfy tens kinds of beam types of railway box beam.

The specific embodiment
Referring to accompanying drawing; The little concrete foundation steel reinforced concrete of a kind of independence beam making bench; Include end concrete foundation 1, several independent little concrete foundations 2 that straight line is successively arranged; Be embedded with steel plate 3 sub-assemblies respectively on end concrete foundation 1, the independent little concrete foundation 2, the steel plate sub-assembly on the independent little concrete foundation 2 is connected with steel pipe post 4 through bolt, and each steel pipe post 4 is positioned on the same horizontal line with steel plate 3 sub-assemblies of end concrete foundation 1; And be connected with steel construction longeron 5 through bolt, be equipped with bed die 6 on the steel construction longeron 5.
Claims (2)
1. the little concrete foundation steel reinforced concrete of independence beam making bench; Include end concrete foundation, several independent little concrete foundations that straight line is successively arranged; It is characterized in that: be embedded with the steel plate sub-assembly respectively on end concrete foundation, the independent little concrete foundation; Steel plate sub-assembly on the independent little concrete foundation is connected with steel pipe post through bolt; The steel plate sub-assembly of each steel pipe post and end concrete foundation is positioned on the same horizontal line, and is connected with the steel construction longeron through bolt, is equipped with bed die on the steel construction longeron.
2. the little concrete foundation steel reinforced concrete of independence according to claim 1 beam making bench is characterized in that: described steel construction longeron is three roads that laterally arrange.
