Technical Field
The invention belongs to the technical field of precast beam construction, and particularly relates to a precast beam making pedestal side width device and an implementation method thereof.
Background
In order to adapt to the change of landform and landform or span other facilities, the length of the precast beam needs to be changed according to local conditions, and the width of the beam bottom of the precast beam is often changed along with the change of the landform and landform, for example, the width of the beam bottom of a 30m T-shaped highway beam is 50cm, while the width of the beam bottom of a 40m T-shaped highway beam is 60cm, so that a corresponding beam-making pedestal needs to be constructed to meet the production requirement. In order to prefabricate multi-model T beams, pedestals of different models need to be built in a beam field, and the traditional construction mode is large in beam field area, high in construction cost and low in pedestal utilization rate. In order to eliminate the disadvantages, the sharing of the beam-making pedestals for the prefabricated T-beams with different lengths is widely used in highway construction, but in the case of beam bottom width variation, beam-making pedestals with different widths are often required to be constructed.

In order to overcome the technical defects of large beam field area, high construction cost, low utilization rate of a pedestal and the like of a beam-making pedestal in the prior art, the invention provides a beam-making pedestal side width device for a precast beam, each segment is smoothly pre-paved on an original beam pedestal, and then is fixed by bolts, so that the original beam pedestal is widened and modified, and the technical problems are solved.
The invention achieves the purpose through the following technical scheme, and the precast beam making pedestal side widening device comprises a pedestal bottom die steel plate, channel steel, nuts and bolts, and is formed by splicing a plurality of sections to meet the requirements of different pre-camber and lifting opening positions of a beam making pedestal, the channel steel is welded at the left end and the right end of the bottom of the pedestal bottom die steel plate, the distance between the channel steel at the two sides is larger than the width of the original beam making pedestal, a through hole is formed in the middle of the channel steel along the length direction, the nut is welded at the position of the through hole, and the bolt is bolted on the nut.
According to the pedestal side width device for the precast beam, the distance between the left and right channel steel at the bottom of the bottom die steel plate of the pedestal is 5-10 mm larger than the width of the original beam pedestal.
An implementation method of a precast beam making pedestal side width device comprises the following use steps:
s1: designing the segment length of the device according to the beam body length and the pre-camber requirement of the precast beam;
s2: smoothly pre-laying each section of the device on the upper end of an original beam pedestal, adjusting the pre-camber which meets the requirement, reserving the position of a beam body lifting opening, clamping each section on the original beam pedestal from channel steels at the left end and the right end of the bottom of a pedestal bottom mould steel plate by using bolts, and welding the sections at the end of the pedestal;
s3: after all the sections are fixed, glass cement is filled in gaps among the sections to prevent slurry leakage of the joints, and slurry stopping strips are placed in the channel openings of the channel steel to complete widening and transformation of the beam-making pedestal.
Generally, compared with the prior art, the technical scheme of the invention can achieve the following beneficial effects: the side widening device for the precast beam making pedestal is reasonable in structural design, each section is smoothly pre-paved on the original beam making pedestal and then is fixed by the bolts, and the original beam making pedestal is widened and reformed.
