Abstract
The utility model discloses a steel pedestal structure for pouring a precast beam. The steel pedestal structure is characterized by comprising a plurality of steel bottom plates which are arranged on the bottommost layer at intervals side by side, wherein a first layer of channel steel, a second layer of channel steel and a third layer of channel steel are arranged above the steel bottom plates sequentially; a plurality of large-size channel steels are arranged in the first layer of channel steel longitudinally side by side along the length direction of a pedestal; a plurality of medium-size channel steels are arranged in the second layer of channel steel transversely side by side along the width direction of the pedestal; a plurality of small-size channel steels are arranged in the third layer of channel steel longitudinally side by side along the length direction of the pedestal; opening sides of the small-size channel steels positioned on two sides in the third layer of channel steel face outwards; and a layer of steel plate is paved above the third layer of channel steel. The steel pedestal structure has the advantages of simple structure and convenience for implementation; when used, the steel pedestal structure can be paved and installed directly without cast-in-place, so that the production time is saved; and the steel pedestal structure can also be moved and used repeatedly, so that the production cost is saved.
Description
Technical field
The utility model relates to science of bridge building, especially relates to a kind of bridge precast beam and builds steel pedestal structure.
Background technology
Along with development of technology, in the construction of contemporary science of bridge building, when carrying out the bridge deck construction, select to adopt the form construction of precast beam more and more, promptly earlier crossbeam is built on-site prefabricatedly, lay being transported to the construction point then.Precast beam is according to length, generally is divided into several kinds of specifications such as 20 meters, 25 meters, 30 meters, 35 meters and 40 meters, and wherein, the precast beam width is also with length incremental variations between 0.5 meter to 1 meter.
In the prior art, when building precast beam, generally be earlier build a coupling earlier according to the size of required precast beam the concrete pedestal as brace foundation, and then on the concrete pedestal, lay steel plate, be that bed die is built with the steel plate.This mode, pedestal can't move, and when the job location changes, often just need near the job location, build the concrete pedestal again, causes waste, and pedestal need be cast-in-place simultaneously, often delays the production time.
The utility model content
Deficiency to above-mentioned prior art; The technical problem that the utility model will solve is: how to provide a kind of precast beam of movable type to build steel pedestal structure; Making it can directly lay installation can use, need not cast-in-place, so saved the production time; Can repeat simultaneously to move and use, save production cost.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of precast beam is built steel pedestal structure; It is characterized in that; Comprise that spacing parallel arranging is arranged at some steel sole plates of the bottom, the steel sole plate top is disposed with ground floor channel-section steel, second layer channel-section steel and the 3rd layer of channel-section steel, vertically is set side by side with some large size channel-section steels along the pedestal length direction in the said ground floor channel-section steel; Laterally be set side by side with some medium size channel-section steels along the pedestal width in the said second layer channel-section steel; Vertically be set side by side with some small size channel-section steels along the pedestal length direction in said the 3rd layer of channel-section steel, the small size channel-section steel open side that is positioned at both sides in the 3rd layer of channel-section steel outwards is provided with, and the 3rd layer of channel-section steel top is equipped with one deck steel plate.Large, medium and small described in this programme is for three layers of channel-section steel, is respectively the relation that the size model increases progressively successively.
The pedestal structure of the utility model, main material is obtained by the channel-section steel of steel plate and three kinds of models, and is simple in structure; It is convenient to implement, though steel pedestal cost is higher than the concrete pedestal, reuses owing to can wholely move; So the whole cost for long-term use will be lower than the concrete pedestal, cast-in-place owing to need not simultaneously, installing and laying can be used; So very convenient quick, do not influence production.The small size channel-section steel open side that wherein is positioned at both sides in the 3rd layer of channel-section steel outwards is provided with, and can directly use as ending slurry pipe mounting groove, and the convenient slurry pipe that ends is installed.
As optimization, the corresponding distributed and arranged of said second layer channel-section steel is in the top of steel sole plate position.Like this, can improve the supporting effect of steel sole plate, guarantee the pedestal bulk strength.
In sum, the utility model possesses simple in structure, implements advantage easily, can directly lay installation during use and can use, and need not cast-in-placely, so saved the production time, can repeat simultaneously to move and use, and has saved production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing the utility model is done further to specify.
During practical implementation; As shown in Figure 1, a kind of precast beam is built steel pedestal structure, comprises that spacing parallel arranging is arranged at some steel sole plates 1 of the bottom; Steel sole plate 1 top is disposed with ground floor channel-section steel 2, second layer channel-section steel 3 and the 3rd layer of channel-section steel 4; Vertically be set side by side with some large size channel-section steels along the pedestal length direction in the said ground floor channel-section steel 2, laterally be set side by side with some medium size channel-section steels along the pedestal width in the said second layer channel-section steel 3, vertically be set side by side with some small size channel-section steels along the pedestal length direction in said the 3rd layer of channel-section steel 4; The small size channel-section steel open side that is positioned at both sides in the 3rd layer of channel-section steel 4 outwards is provided with, and the 3rd layer of channel-section steel 4 top are equipped with one deck steel plate 5.Said second layer channel-section steel 3 corresponding distributed and arranged are in the top of steel sole plate 1 position.
During practical implementation, the utility model can be used as many groups, splices the back according to the length of precast beam during installation and uses, and can avoid long like this and is unfavorable for transportation.
Claims (2)
