Abstract
Aiming to overcome the disadvantage of incapability of giving consideration to formwork precision, manufacturing cost and manufacture period in a conventional support frame system, the invention provides a support frame system for a box girder. The support frame system for the box girder comprises a full framing, wherein box girder supporting units are arranged at the top of the full framing, and the box girder supporting units are arranged in an array manner in the length extension direction of the framing; adjacent box girder supporting units are fixedly connected through a gag lever post; each box girder support unit is composed of a pair of supporting unit components in mirror symmetry; each supporting unit component is composed of a side lever, a bottom bar, a girder, an adjustable support rod and a jacking rod; the support frame system for the box girder has the beneficial technical effects that the manufacturing cost is low, the processing period is short, the mould precision is high, the operation is convenient during the use, the construction accuracy is ensured, and the construction cost is saved.
Description
Technical field
The invention belongs to technical field of building construction, particularly relate to the bracing frame system for case beam, be specially adapted to the construction equipment of railroad bridge.
Background technology
Along with the development of Chinese Railway, case beam is widely used in railroad bridge with its superior performance.But the case beam sidewall line of curvilinear structures and the linear shape more difficult control in construction of frange plate, accurate controlling curve section sidewall and frange plate linear be ensure and improve case beam apparent size and linear technological difficulties.Existing solution has three kinds, is respectively lumps of wood steel pipe support support body, large scale steel mould supporting frame and steel pipe scaffold supporting frame.Above-mentioned three kinds of equal existing defects of method, are followed successively by: the topmost advantage of lumps of wood steel pipe support support body 1, as cast-in-situ box girder or the most general support system of abutment cast-in-place construction is good in economic efficiency, draws materials conveniently, are applicable to construction on a small scale; But shortcoming is the mould and support insecure generation absolute altitude deviation of easily rising in construction.2, adopt the advantage of the large scale steel mould supporting frame of complete sizing punching block support system to be firm supporting, can adjust frange plate absolute altitude, box girder construction quality is better; But it is long that shortcoming is fabrication cycle, and cost is higher.3, steel pipe scaffold supporting frame, namely full hall scaffold construction construction of cast-in-situ box-beam scheme, advantage is that frange plate support system is integrated with beam body support system, support system bearing capacity and rigidity better; Shortcoming is that curvilinear sidewall reinforcing still adopts lumps of wood steel pipe support, easy production cross section dimensional errors in construction.
Summary of the invention
For the drawback that the mould bases precision of existing bracing frame system and manufacturing cost, manufacturing cycle can not get both, the invention provides a kind of bracing frame system for case beam.Its concrete structure is as follows:
For the bracing frame system of case beam, comprise full hall bracing frame 1, in addition, be provided with case beam support unit at the top of full hall bracing frame 1, case beam support unit is the arrangement of array along the direction that full hall bracing frame 1 length extends; Be fixedly connected with by gag lever post 7 between adjacent case beam support unit;
Each case beam support unit forms by a pair support unit assembly in specular; Each support unit assembly forms by side lever 2, bottom bar 3, stupefied bone 4, adjustable support rod 5 and push rod 6;
Wherein, stupefied bone 4 is the steel construction piece of arc; Side lever 2 and push rod 6 are the concrete filled rectangular steel tube members part of hollow; Adjustable support rod 5 is made up of supporting steel pipe fitting and steel pipe socket two parts, and supporting steel pipe fitting is inserted in the adjustment hole of steel pipe socket, is regulated the entire length of supporting steel pipe and steel pipe socket by bolt;
The bottom of side lever 2 is connected with the medial end of bottom bar 3, and can rotate around the connecting axle of side lever 2 with bottom bar 3; The top of side lever 2 is connected with bottom bar 3 by an adjustable support rod 5; Namely by regulating the length of the adjustable support rod 5 be connected with side lever 2, the corner dimension between side lever 2 and bottom bar 3 is regulated;
The outboard end of push rod 6 is connected with the outboard end of bottom bar 3 by an adjustable support rod 5, the medial end of push rod 6 is connected with bottom bar 3 by another root adjustable support rod 5, namely by regulating the length of two adjustable support rods 5 be connected with push rod 6, the distance between push rod 6 and bottom bar 3 and corner dimension is regulated;
The bottom of stupefied bone 4 is connected with the top of side lever 2, and the top of stupefied bone 4 is connected with push rod 6 medial end;
The stage casing of stupefied bone 4 is at least fixedly connected with an adjustable support rod 5 between bottom bar 3 stage casing corresponding thereto.
useful technique effect
1, the low cost of manufacture of this product, process-cycle precision that is short, mould are high and in use easy to operate, the precision guaranteeing to construct, save construction cost;
2, the radian of this product working face is determined by the assembly relation of side lever 2, bottom bar 3, stupefied bone 4, adjustable support rod 5 and push rod 6, can carry out the correction on radian for different object of construction production and bridge construction, avoiding complete customization part can only disposable drawback;
3, this product is installed simple, applied widely;
4, this product is particularly suitable for the construction of the box-beam structure with shaped form side, overcomes traditional construction auxiliary stand and cannot guarantee the precision of radian and conforming construction difficult problem.
