Mountain high-speed line type zigzag, the straight line bridge is few almost, is located the curve of circle and gentle curve mostly, and the curve between the bridge span passes through inside and outside cantilever value formation of boundary beam, and the camber is big more, and the T roof beam prefabrication degree of difficulty is big more. This project relates to 186 kinds of boundary beam cantilever parameters, for practicing thrift construction cost, does not consider every kind of cantilever parameter configuration one set of pterygoid lamina side forms, realizes the curve requirement through cantilever adjusting device, and current adjusting device uses convenience inadequately, and the accuracy is not high.
Disclosure of Invention
In order to solve the problem that proposes among the background art, the utility model provides a prefabricated cantilever adjusting device of concrete T roof beam convenient, with low costs and safe convenient of preparation.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model provides a cantilever adjusting device for concrete T roof beam is prefabricated, includes steel form, slip triangular supports frame, bolt and scale, the steel form constitute 40 meters T roof beam boundary beam pterygoid lamina side forms by 40 1.0 meters long little steel forms, slip triangular supports frame locates the steel form back, every little steel form establishes two slip A-frames, slip angle steel for the A-frame and steel reinforcement welding form, slip A-frame angle steel bottom links to each other with the pterygoid lamina die block through the bolt, has the scale on the A-frame angle steel.
Furthermore, the set of T-beam flange plate edge molds are provided with 60 sliding triangular supports.
Furthermore, the graduated scale of slip A-frame bottom set up at angle steel bottom back, prevent to pour the process concrete pollution.
The utility model has the advantages that:
the utility model discloses the preparation adopts ordinary steel form, angle steel, bolt, reinforcing bar, scale welding to form, and the preparation is convenient, with low costs, adjust the accuracy height, convenient to use and resources are saved, can solve the changeable boundary beam pterygoid lamina cantilever parameter that leads to of mountain area highway concrete T beam bridge line type loaded down with trivial details, the line type is not in the same direction as, the big problem of template cost input. The angle steel bottom of support frame has the scale, adjustment cantilever parameter that can be accurate, and it is convenient to adjust, and the precision is high, and the T roof beam line type that prefabricated out is smooth-going, camber accord with the design requirement.
The utility model discloses great degree the reduction of boundary beam pterygoid lamina boundary die's input has improved the prefabricated quality of T roof beam, can solve inside and outside cantilever adjustment line shape difference, complex operation in the past T roof beam, and template and labour drop into big problem, in addition, when the concrete T girder bridge boundary beam that camber is bigger is prefabricated, is the length that needs the little steel mould of subtract, just can let the boundary beam in, outer cantilever value more smooth-going.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a usage state diagram of the present invention.
In the figure, 1-small steel die, 2-C22mm steel bars, 3-angle steel of 7.5cm, 4-sliding pads (angle steel), 5-M20 bolts and 6-graduated scales.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in detail the preferred embodiments of the present invention to facilitate understanding of the technical staff.
The utility model provides a cantilever adjusting device for precast concrete T roof beam, includes steel pipe 1, little steel mould 2, C22mm reinforcing bar 3, angle 7.5cm angle steel 4, sliding platform (angle steel) 5, M20 bolt, 1.0 meters of little steel mould length, two kinds 0.18 meters (30 meters T roof beam) and 0.2 meters (40 meters T roof beam) high, 30 meters T roof beam per set of template need dispose 30, 40 meters T roof beam need dispose 40, connect through the preformed hole between the little steel mould. Little steel mould back sets up slip triangular support, and slip triangular support comprises C22mm reinforcing bar 2 and angle steel 3 of 7.5cm, and slip triangular support plays to support and draws the slip effect, and reinforcing bar 2 forms the bracing at the steel form back, bears the horizontal atress when concrete placement, and angle steel 3 is the device's sliding member, and the angle steel back has scale 6, and the scale setting of slip triangular support bottom is at the angle steel bottom back, prevents to pour process concrete pollution. The scale measures the horizontal distance to be moved of the steel template, the scale is accurate to millimeter, the accuracy meets the requirement of a drawing, when the steel template moves to the maximum stroke, the cantilever value is 130 centimeters, when the cantilever parameter is 120 centimeters, the scale reads 10 centimeters, and the operation is convenient and simple. The sliding pad is an angle steel 4 fixed on a lower template system, an M20 bolt 5 is fixed on the sliding pad, a preformed hole is formed in the sliding surface of the sliding triangular support, the bolt 5 penetrates through the preformed hole, the bolt is loosened when the sliding triangular support needs to slide, the sliding triangular support can move transversely, the small steel mold slides according to cantilever parameters, the reading of the graduated scale is adjusted, the bolt is fixed after the reading is confirmed, and the adjustment of the cantilever value is completed. One set of T-beam flange edge molds has 60 sliding triangular supports.
When reducing steel mould length, increase on the cantilever parameter T roof beam prefabrication that slip A-frame quantity can be applicable to the camber bigger, it is more convenient to increase the scale operation on the slip A-frame, does not need the chi volume when every adjusting device is flexible, and the precision is high, and it is more convenient to use.
