Specific embodiment
For that can further appreciate that the contents of the present invention, feature and effect, make below by specific embodiment further detailed
State, following implementation be it is descriptive, be not restrictive, this does not limit the scope of protection of the present invention.
A kind of production method of hyperboloid steel box-girder moulding bed, specific implementation step are as follows:
Step 1: preparing an assembly platform, steel structure platform or concrete platform is can be used in platform, and the flatness of platform is not
Greater than 5mm, create conditions conducive to the accurate control of subsequent operation.
Step 2: the steel box-girder top plate plant tilting figure provided according to design drawing is it is found that in steel box-girder top plate in outer arc and road
Heart line plane projection is easement curve, therefore can make a reference line in projection plane extra curvature, and reference line is apart from outer arc outer rim
Point of contact 1m marks the size between reference line and outer arc curve and diaphragm plate intersection point, and the outer arc provided according to design drawing with every
Lateral dimension between plate intersection point determines the plane coordinates anchor point (X, Y coordinates) of moulding bed outer arc, similarly, determines the flat of moulding bed inner arc
Areal coordinate anchor point.(see attached drawing 1)
It is longitudinal datum mark (height 500mm) with outer arc end point and partition intersection point, goes out according to bridge head fall
Arc intersects the vertical dimension of each point with partition, to determine the Z-direction coordinate of moulding bed outer arc (see attached drawing 2).With outer arc datum mark, according to
Bridge floor cross fall calculates the perpendicular of inner arc end point, end road axis, end web center line and diaphragm plate crosspoint
To size, and press head fall, the vertical dimension that inner arc, road axis intersect to each point with partition calculate (see attached drawing 3,
4) vertical dimension that web line intersects each point with partition, can be similarly calculated, road axis, web line vertical dimension should subtract
Calculated bridge floor transverse direction camber value according to actual needs.
Make a little step 3: spacer lines are extended 50mm to moulding bed outside direction along inside and outside arc and spacer lines crosspoint, with this point
As column bottom plate side center, and base plate center line should be coincided with spacer lines (see attached drawing 5), determine that interior outer arc moulding bed is vertical with this
The position of column, moulding bed column should be centered on partition and road axis intersection point at road axis.
Step 4: by column bottom plate and platform welding, and cross hairs is got on bottom plate, column center is marked, to stand
Column installation positioning.Column bottom plate is made of steel plate, and thickness is not less than 10mm, and moulding bed column uses the H-type qualified by checking computations
Steel.
Step 5: using the intersection point of moulding bed outer arc and partition as datum mark, the inner arc provided according to step 2, outer arc, road
Lu Zhizheng line and spacer lines crosspoint longitudinal size subtract moulding bed deck-molding and column base plate thickness gauge calculates the height of moulding bed column.
Step 6: making moulding bed beam according to spacer lines length blanking in step 2, moulding bed beam uses the H qualified by checking computations
Fashioned iron or channel steel.
Step 7: according to bottom plate position line and height, successively installation group is welded by the column of blanking well cutting.Column installs
Afterwards, moulding bed beam group is soldered on column (see attached drawing 6) along partition direction.
8th step makes the rib of slab of 100*200 to adjust moulding bed beam column absolute altitude installation error, on moulding bed beam along top plate
Rib of slab (see attached drawing 6) is respectively welded in camber line at outer camber line, road axis and box girder web, adjusts rib of slab by transit survey
Absolute altitude (cutting the part for being higher by corresponding absolute altitude) keeps moulding bed vertical and horizontal gradient and steel box-girder top plate vertical and horizontal gradient completely the same.
Step 9: setting up bridging and diagonal brace between column transverse and longitudinal, increase the stability of moulding bed.Bridging and diagonal brace
It is made using not small with the bis- back equal leg angles of 40*4.
Step 10: installing hyperboloid steel box-girder on the moulding bed made.
The present invention guarantees that Deck reaches and sets by making the space curved surface moulding bed to fit like a glove with Deck coordinate
Meter requires, to guarantee steel box-girder production precision and construction quality, improves steel box girder construction speed.
The present invention is not limited to embodiments described above.Above the description of specific embodiment is intended to describe and say
Bright technical solution of the present invention, above-mentioned specific embodiment are only to illustrate, and are not restrictive.This hair is not being departed from
In the case of bright objective and scope of the claimed protection, those skilled in the art can also do under the inspiration of the present invention
