Abstract
A precast beam pedestal construction technology comprises the steps of measuring and wire stringing; conducting basic excavation; performing foundation carrying capacity detection, basic cushion concrete pouring and basic steel bar colligation; then performing basic concrete pouring, pedestal steel bar binding, pedestal template installation, pedestal concrete pouring and pedestal steel plate laying; and finally welding channel steels at two sides. The problem that the precast beam construction production is influenced due to landform condition restriction and small beam land area is solved; beam land construction time and precast beam construction period are shortened; bean land construction cost is reduced; construction cost is greatly reduced; the normal construction of the precast beam lays a solid foundation for the normal development of subsequent engineering like floor erection and bridge floor construction, and guarantees the smooth construction of the project engineering.
Description
Technical field
The present invention relates to a kind of beam Precasting Pedestal Construction technique, specifically precast beam Precasting Pedestal Construction technique.
Background technology
Original precast beam Precasting Pedestal Construction needs relatively place, crossbeam field, and construction speed is slow, and construction quality is low, and construction cost is high, and Liang Chang takes over the land for use and smooth expense, precast pedestal construction cost height.
Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of precast beam Precasting Pedestal Construction technique.
The present invention is for achieving the above object, it is achieved through the following technical solutions: precast beam Precasting Pedestal Construction technique, first carry out surveying setting-out, carry out foundation excavation again, then foundation bearing capacity detection, blinding layer concrete placings and reinforcement foundation colligation are carried out, it is sequentially carried out that foundation concrete is built, pedestal reinforcing bar binding, pedestal model sheetinstallat, pedestal concrete placings and pedestal steel plate are laid, and finally carry out both sides channel-section steel welding again.
For realizing the purpose of the present invention further, it is also possible to by the following technical solutions: pre-embedded steel slab installation site adjustment �� seam crossing polishing at the bottom of preparation of construction �� dismounting 30m pedestal side channel-section steel �� widened section angle steel welding, the welding of reinforcing �� channel-section steel, reinforcing �� beam. Before 30m beam making bench changes the construction of 40m beam making bench, first have to the preparation before carrying out the construction such as material purchase, machinery allotment, personnel placement, buy sufficient angle steel (10 �� 10cm), channel-section steel (5#), �� 22 reinforcing bar, expansion bolt (�� 12), welding rod (502), horizon rule etc. according to pedestal quantity, select the skilled industrial worker that solder technology is really up to the mark. Weld 10 �� 10cm angle steel, angle steel side and base steel plate end face level in former 30m beam making bench side, opposite side and concrete base side are close to, and angle steel docks with steel plate closely, and apical side height is consistent, firm welding, measure accurately with horizon rule before welding; After angle steel has welded, bottom angle steel, each rice slate pencil makes marks, and cuts the semicircle of a diameter 3cm with gas cutting, punches at this place and installs expansion bolt, screw support angle steel, it is ensured that angle steel is stable.
It is an advantage of the current invention that: the invention solves because orographic condition limits, Liang Chang place is less, affect the problem that precast beam construction produces, decrease beam fabricating yard construction time and precast beam construction period, reduce the expenses such as beam fabricating yard construction, largely reduce construction cost, the normal construction of precast beam, established solid foundation for normally carrying out of successive projects such as beam slab erection, bridge deck constructions, for project construction be smoothed out provide sound assurance.

Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Precast beam Precasting Pedestal Construction technique, first carry out surveying setting-out, carry out foundation excavation again, then foundation bearing capacity detection, blinding layer concrete placings and reinforcement foundation colligation are carried out, it is sequentially carried out that foundation concrete is built, pedestal reinforcing bar binding, pedestal model sheetinstallat, pedestal concrete placings and pedestal steel plate are laid, and finally carry out both sides channel-section steel welding again.
Pre-embedded steel slab installation site adjustment �� seam crossing polishing at the bottom of preparation of construction �� dismounting 30m pedestal side channel-section steel �� widened section angle steel welding, the welding of reinforcing �� channel-section steel, reinforcing �� beam.
Before 30m beam making bench changes the construction of 40m beam making bench, first have to the preparation before carrying out the construction such as material purchase, machinery allotment, personnel placement, buy sufficient angle steel (10 �� 10cm), channel-section steel (5#), �� 22 reinforcing bar, expansion bolt (�� 12), welding rod (502), horizon rule etc. according to pedestal quantity, select the skilled industrial worker that solder technology is really up to the mark.
Weld 10 �� 10cm angle steel, angle steel side and base steel plate end face level in former 30m beam making bench side, opposite side and concrete base side are close to, and angle steel docks with steel plate closely, and apical side height is consistent, firm welding, measure accurately with horizon rule before welding; After angle steel has welded, bottom angle steel, each rice slate pencil makes marks, and cuts the semicircle of a diameter 3cm with gas cutting, punches at this place and installs expansion bolt, screw support angle steel, it is ensured that angle steel is stable.
After angle steel has been constructed, weld channel-section steel (5#) in angle steel bottom surface, channel-section steel opening outwardly, outside and angle steel justified margin, firm welding, for ensureing that channel-section steel is reinforced stable, it is supported every two �� 22 reinforcing bars of one meter of use bottom channel-section steel, reinforcing bar one end and channel-section steel bottom welding, the other end is supported on pedestal basis and pedestal abutment body, firm welding, supporting & stablizing, it is ensured that channel-section steel is reinforced stable.
With pre-embedded steel slab reserved location at the bottom of the beam of epoxy resin mortar filling-in former 30m beam making bench end, and installed base steel plate, steel plate is installed and dock with both sides steel plate, it is ensured that docking and smooth out, firm welding, seam crossing powder of lacquer putty for use on is clogged, it is ensured that tight.
Checking whether angle steel and channel-section steel welding be firm, it has been found that the timely repair welding of problem is reinforced, with abrasive cutoff saw butt welding contact and there is the position of faulting of slab ends and polish, it is floating that the place powder of lacquer putty for use on that seam is bigger carries out filling, it is ensured that seam is tight, not spillage.
Technical scheme is not restricted in the scope of embodiment of the present invention. The technology contents of the not detailed description of the present invention is known technology.
