Trestle
Technical field
The utility model relates to a kind of trestle.
Background technology
Deep foundation ditch soil excavation and ultra dark underground structure construction are through being provided with trestle to guarantee cubic metre of earth a transportation and a transport of materials.Conventional trestle construction adopts the pre-buried angle steel lattice column of drill hole pouring pile as piling strtucture; After laying the steelframe trussed construction above the piling strtucture, In-situ cast concrete board up again, this trestle complex structure; Constructional difficulties; Work progress takies the critical circuits duration, influences total construction period, and input cost is excessive.And this conventional trestle is removed the back material does not have the recovery space basically, can only do waste disposal.
Summary of the invention
The purpose of the utility model is to provide a kind of trestle, and its construction and installation are quick, and is less to the influence of total construction period, and material is recyclable to be utilized again.
The purpose of the utility model realizes through following technical scheme: a kind of trestle is characterized in that: it comprises more than two groups the pile tube group laid at interval successively along the longitudinal direction, fixed mount is located at crossbeam, two bridge floor main bodys of being located at the crossbeam top and being distributed in the longeron of different lateral attitudes and being layed in the longeron top with upper holder of respectively organizing on the pile crown of pile tube group top and extending along horizontal direction respectively; Every group of pile tube group comprises two perpendicular pile tubes of putting and laying along horizontal interval successively.
Adopt tube pile structure, need not to carry out the pre-buried piling strtucture of drill hole pouring pile in the feasible construction; Steel structure truss improves horizontal longeron system.So not only simplified structure reduces working procedure, practices thrift the engineering time, and is convenient to the utilization again of structure member.
The utility model has also carried out following improvement:
Said bridge floor main body comprises that fixed mount is located at longeron top and many horizontal retaining pieces laying at interval successively along the longeron bearing of trend and be set up in the longeron top and be embedded at the prefabricated concrete plate between the adjacent two horizontal retaining pieces; Thereby substitute the job practices of traditional In-situ cast concrete board; Not only effectively shorten the construction period, and can reuse.
Between adjacent two root canal piles of same pile tube group, be connected fixing with first bridging through first waling stripe.
Between two root canal piles of same lateral attitude, be connected fixing with second bridging in the adjacent two pile tube groups through second waling stripe.
Top, the vertical both sides of said bridge floor main body is arranged with guard rail.
Said pile tube is for shaking towards steel pipe pile, and crossbeam and longeron are respectively steel I-beam, and laterally retaining piece is a channel-section steel.
Compared to prior art, the advantage of the utility model is: simplified structure not only, reduce working procedure, and practice thrift the engineering time, effectively reduce total construction period, and be convenient to the recycling of structure member, practice thrift construction cost greatly.

The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
Embodiment sketch map like Fig. 1, Fig. 2 and a kind of trestle that provides for the utility model shown in Figure 3.
A kind of trestle is characterized in that: it comprises more than two groups the pile tube group laid at interval successively along the longitudinal direction, fixed mount is located at the crossbeam respectively organizing on the pile crown of pile tube group top and extend along horizontal direction 1, two bridge floor main bodys of being located at crossbeam 1 top and being distributed in the longeron 2 of different lateral attitudes and being layed in longeron 2 tops with upper holder respectively; Every group of pile tube group comprises two perpendicular pile tubes 3 of putting and laying along horizontal interval successively.
Said bridge floor main body comprises that fixed mount is located at longeron 2 tops and many horizontal retaining pieces 4 laying at interval successively along longeron 2 bearing of trends and be set up in longeron 2 tops and be embedded at the prefabricated concrete plate 5 between the adjacent two horizontal retaining pieces 4.
Between adjacent two root canal piles 3 of same pile tube group, be connected fixing with first bridging 7 through first waling stripe 6.
Between two root canal piles 3 of same lateral attitude, be connected fixing with second bridging 9 in the adjacent two pile tube groups through second waling stripe 8.
Said bridge floor main body both lateral sides top is arranged with guard rail 10.
Said pile tube 3 is for shaking towards steel pipe pile, and crossbeam 1 is respectively steel I-beam with longeron 2, and laterally retaining piece 4 is a channel-section steel.
