Description
Technical field
The invention belongs to technical field of building construction, relate in particular to the bracing frame system for the case beam, be specially adapted to the construction equipment of railroad bridge.
Background technology
Along with the development of Chinese Railway, the case beam is widely used in railroad bridge with its superior performance.But shape more difficult control in construction that the case beam sidewall line of curvilinear structures and frange plate are linear, accurately controlling curved section sidewall and frange plate linear is to guarantee and raising 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.All there is defect in above-mentioned three kinds of methods, are followed successively by: 1, the topmost advantage of lumps of wood steel pipe support support body 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, is 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 typing punching block support system to be firm supporting, can adjust the frange plate absolute altitude, the 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, i.e. the construction of cast-in-situ box-beam scheme of full hall scaffold construction, advantage is that frange plate support system and beam body support system are integrated, support system bearing capacity and rigidity are better; Shortcoming is that lumps of wood steel pipe support is still adopted in the curvilinear sidewall reinforcing, easily produces the sectional dimension deviation in construction.
Summary of the invention
Drawback for the mould bases precision of existing bracing frame system and manufacturing cost, manufacturing cycle can not get both, the invention provides a kind of system of bracing frame for the case beam.Its concrete structure is as follows:
The bracing frame system that is used for the case beam, comprise full hall bracing frame 1, in addition, at the top of full hall bracing frame 1, is provided with case beam support unit, and the direction that case beam support unit extends along full hall bracing frame 1 length is arranging of array; Be fixedly connected with by gag lever post 7 between adjacent case beam support unit;
Each case beam support unit forms by a pair of support unit assembly that is the mirror image symmetry; 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 spare of hollow; Adjustable support rod 5 is comprised of supporting steel pipe fitting and steel pipe socket two parts, and the supporting steel pipe fitting is inserted in the adjustment hole of steel pipe socket, regulates 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 be around the connecting axle rotation 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 that is connected with side lever 2, regulate the corner dimension between side lever 2 and bottom bar 3;
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 being connected with push rod 6, between adjusting push rod 6 and bottom bar 3 apart from distance and corner dimension;
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 ends;
The stage casing of stupefied bone 4 is fixedly connected with an adjustable support rod 5 between bottom bar 3 stage casings corresponding with it at least.
Useful technique effect
1, the low cost of manufacture of this product, process-cycle precision short, mould are high and in use easy to operate, guarantee the precision of constructing, 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 correction on radian for different object of construction production and bridge construction, avoid the complete customization part can only disposable drawback;
3, this product is installed simple, applied widely;
4, this product is particularly suitable for having the construction of the box-beam structure of shaped form side, overcomes tradition construction auxiliary stand and can't guarantee precision and the conforming construction difficult problem of radian.
