Abstract
The present invention relates to a belt conveyer trestle bridge with plate-shell structure, including foundation, supporting clumns connected with the foundation, cross-over portion installed on the supporting columns and roof covering the cross-over portion, the foundation, supporting columns and cross-over portion are of thin-wall structure, and the ratio of its height and thickness is greater than 10. Its advantages are: light dead-weight, large span of 6-42 m., good shock resistance and low cost.
Description
The present invention relates to technical field of buildings, specifically a kind of belt transporter trestle of plate and shell structure.
Present belt transporter trestle kind is a lot, and brickwork construction is arranged, and ferro-concrete, brick mix structure are arranged, and full steel structure is also arranged.Generally from heavy, span is little for above structure, and it is big to consume building materials, though full steel structure is in light weight, but make large span, but the cost height, poor durability, service expenditure height.
The objective of the invention is to design a kind of from heavy and light, span is big, and cost is low, and the reinforcing bar of long service life mixes the belt transporter trestle of earth plate and shell structure.
The plate and shell structure belt transporter trestle of ferro-concrete of the present invention comprises the frid of putting upside down, or the bucket type plate, or the basis of just tieing up shell, T type post or L type post, or
The support column of type post, the leap part of two-way thin-walled frid beam body, thin wall lattice configuration plate, or form boarding, or the roofing of long barrel shell plate of single wavestrip rib or two-fold flap.
Thin-walled frid beam, the thin wall lattice configuration plate, long barrel shell plate of form boarding list wavestrip rib or two-fold flap all are the thin-wall reinforced concrete members, the ratio of the height of thin-wall member and thickness is all greater than 10.
Xia Mian enumerates thick, the high size relationship of thin-walled frid beam such as Xia table, the accompanying drawing Shun Xu 12345678 thick b 100 100 100 100 100 100 100 100 accompanying drawing Shun Xu 9 10 11 12 13 14 thick b 100 100 100 100 100 100 in high h＞2200＞2200＞2200＞2200＞1000＞1000 in high h＞1000＞1000＞1000＞1000＞1000＞1000＞2200＞2200 with reference to the accompanying drawings
From showing h/b＞10 as can be seen
The width of trestle of the present invention can be designed into 2.5～12m, and span can design can 6～42m.According to different width and span requirement, can select for use by accompanying drawing.If the width I is selected accompanying drawing 1～3 type for use, if width can be selected 4～6 types for use greatly, if span can be selected accompanying drawing 7～12 types greatly for use.Its method of calculating all can calculate with methods of calculating such as H-girder and relevant flap and housings by the T plate-girder.Its structure requires to add anti-swirl pot in the plate domestic demand that encrusts, and adding anti-swirl pot is to prevent the bent distortion of structure wing, increases stability.
Advantage of the present invention be trestle from heavy and light, have only originally 1/2～2/3, span is big, can be 6～42 meters, anti-seismic performance is good, cost is low, can save civil engineering investment 20～40%, construction speed is fast, can shift to an earlier date the engineering time 1/4～1/3.Long service life, good looking appearance.
Below in conjunction with accompanying drawing embodiment is elaborated:
Fig. 1～Figure 14 is the section drawing of leap partial sum roofing of the belt transporter trestle of plate and shell structure.
Figure 15 is the trestle schematic overview.
Figure 16 is the trestle schematic overview.
Figure 17 is a trestle top barrel shell arrangement of reinforcement.
Figure 18 is a trestle lower channel plate-girder arrangement of reinforcement.
Figure 19 is the assumed (specified) load scheme drawing.
Striding 18.0m with wide 3.0m is that the example brief calculation is as follows:
18.0m be freely-supported, lotus P=300kg/m lives
2, dead load frid beam is 700kg/m one) and its computing formula such as Figure 19
Span centre bending moment M
In=1/10qp

Bearing bending moment M
End=1/40ql

Shear force Q
1=R
2=R
2=1/2ql ... 3. calculate q=1.5 * 300+700=1150kg/m
M
In=1/10 * 1150 * 18
2=372660kg
M
=1/40 * 1150 * 18
2=9315kg
Q

Can merge into I-shape by flute profile or double flute and add the section table that double B and Q look into the relevant height of steel concrete, arrangement of reinforcement can be obtained the main stress muscle.
Two) arrangement of reinforcement is constructed as follows figure:
(1) top barrel shell arrangement of reinforcement such as Figure 17
Tabula thickness of slab 80, join two guiding principle φ 6 and 1. join 2 φ 12 for 100 times
(2) lower channel plate-girder arrangement of reinforcement such as Figure 18
Can be with two-way hoop arrangement of reinforcement when (3) support column is T shape or L shaped thin plate.
(4) basis can be by various shells and flap arrangement of reinforcement.
Above support column, the arrangement of reinforcement on basis are conventional arrangements of reinforcement.Part is crossed on the support column basis, and arrangements of reinforcement such as roofing are carried out the back concrete placing.The ratio of the height of its ready-made reinforced concrete structure and thickness is greater than 10.
Claims (3)
- The belt transporter trestle of a plate and shell structure, comprise basis (1), supporting stack (2) is crossed over part (3), roofing (4) is characterized in that crossing over part (3) and is two-way thin-walled frid beam body, the ratio of its height and thickness is greater than 10.
