Abstract

The utility model relates to a concrete track roof beam that bottom plate opening, roof hung is applied to among the suspension type mono -rail transport system civil construction. A concrete track roof beam that bottom plate opening, roof hung, passes through that the roof both ends of concrete beam (1) are pre -buried to have base (3a) and a base (3b), and cable (5a) passes the cable pore (4a) of base (3a), and cable (5b) passes the cable pore (4b) of base (3b), hangs the below at the concrete bridge pier capping beam to concrete beam (1). The utility model provides a concrete track roof beam that bottom plate opening, roof hung, replaced current steel box beam, prevent atress bucking phenomenon, vehicular load and shock resistance that the increase was born reduce the deformation of track roof beam, are favorable to the linear control of track roof beam, improve the durability of track roof beam.

Description

The concrete track beam that a kind of base plate opening, top board hang

Technical field

The concrete track beam that this patent relates to a kind of base plate opening, top board hangs, is applied to suspension type monorail In traffic system civil engineering.Specifically in suspension type monorail traffic system, with mixing of base plate opening The track that solidifying soil track girder travels as monorail train.

Background technology

German Eugen Langen in 1893 has invented suspension type monorail traffic, and is writing in 1898-1901 City-Wu Pata the city, Ruhr Region in Germany (Wupppertaler) of the outstanding car of name has built the suspension type monorail ferrum of 13.3km Road, this is the most the earliest, to be also suspension type monorail traffic with the longest history.Henceforth, Germany The Chiba city of Dortmund, Dusseldorf and Japan, Prefectura de Kanagawa etc. have built certain mileage the most in succession Suspension type monorail railway.The suspension type monorail traffic route of a formal operation, weight is not also had at present in China The cross-saddle single-track traffic circuit of celebrating is the monorail transit circuit that China is few in number.

Civil engineering structure many employings steel constructions such as the existing track girder in suspension type monorail traffic system and bridge pier Form, i.e. employing steel tank ellbeam is as track girder, by steel column by overhead for track girder unsettled.Steel track Two that beam is corresponding on steel bridge pier capping beam by being arranged on two metal supporting leg freely-supporteds outside steel tank ellbeam Above metal support, form steel tank ellbeam freely-supported by Force system.This steel tank ellbeam is little because of steel plate thickness, Stress flexing phenomenon easily occurring, causes its vehicular load carried little, unfavorable to antidetonation, track girder easily produces Raw bigger deformation, is unfavorable for the alignment control of track girder；Steel construction is also easy to corrosion, affects its durability.

Having had some researchs for track girder at present, partial monopoly situation is as follows:

Application publication number is that the utility model patent " a kind of box track beam structure " of CN 203716059 U is public Having opened a kind of box track beam structure, this utility model provides the coagulation of remaining silent that a kind of bottom is tension compression bearing Soil box track beam structure, is not particularly suited for existing suspension type monorail vehicular traffic system.

Application publication number is the patent of invention " straddle-type monorail steel-mixed combined track beam " of CN 104233947 A Having invented a kind of steel for straddle-type monorail transportation system-mixed combined track beam, its stress system is bottom cloth Putting tension compression bearing, this patent can not be as the track girder of suspension type monorail traffic system.

Above patent is suitable only for bottom and arranges the track girder stress form of tension compression bearing, is all not directed to outstanding The track girder that hanging monorail traffic system base plate opening, top board hang.A kind of base plate opening of this patent general's offer, The concrete track beam that top board hangs.

Utility model content

Technical problem to be solved in the utility model is:

For suspension type monorail traffic system, it is provided that the concrete track beam that a kind of base plate opening, top board hang, Replacing existing steel tank ellbeam, this steel tank ellbeam is little because of steel plate thickness, easily occurs stress flexing existing As, cause its vehicular load carried little, unfavorable to antidetonation, track girder is easily generated bigger deformation, unfavorable Alignment control in track girder；Steel construction is also easy to corrosion, affects its durability.

This utility model solves its technical problem and be the technical scheme is that

A kind of base plate opening, top board hang concrete track beam, including concrete beam body 1, spigot surface 2-1a, Spigot surface 2-1b, running face 2-2a, running face 2-2b, base 3a, base 3b, drag-line duct 4a, drag-line Duct 4b, is characterized in that: the top board two ends of concrete beam body 1 are embedded with base 3a and base 3b, drag-line 5a is through the drag-line duct 4a, drag-line 5b of base 3a through base 3b drag-line duct 4b, beams of concrete Body 1 is suspended on the lower section of concrete bridge pier capping beam.

The beneficial effects of the utility model are:

The concrete track beam that a kind of base plate opening, top board hang, instead of existing steel tank ellbeam, anti- Only there is stress flexing phenomenon, increase vehicular load and the shock resistance of carrying, reduce the deformation of track girder, Be conducive to the alignment control of track girder, improve the durability of track girder.

Detailed description of the invention

In conjunction with example, this utility model is described further.

The concrete track beam that example suspension type monorail traffic system have employed base plate opening, top board hangs, Employ concrete beam body 1, spigot surface 2-1a, spigot surface 2-1b, running face 2-2a, running face 2-2b, Base 3a, base 3b, drag-line duct 4a, drag-line duct 4b, drag-line 5a, drag-line 5b.

In the step 1 workshop beam stage, the steel reinforcement cage of colligation concrete beam body 1, at the two ends of roof steel bar cage At design attitude, place the base 3a and the base 3b of reserved drag-line duct 4b of reserved drag-line duct 4a, water Build concrete beam body 1.

Step 2 transports erection scene prefabricated concrete beam body 1, and lifting concrete beam body 1 is to mixed Design attitude below solidifying soil pier cap beam, passes the drag-line duct 4a, drag-line 5b of base 3a by drag-line 5a Through the drag-line duct 4b of base 3b, concrete beam body 1 is suspended on the lower section of concrete bridge pier capping beam, this The construction of the concrete track beam that sample just completes base plate opening, top board hangs, as depicted in figs. 1 and 2.

The above, be only the preferred embodiment of this patent, not makees this patent any pro forma Limiting, any simple modification, equivalent that above example is made by the technical spirit of every foundation this patent become Change and modify, all still falling within the range of the art of this patent scheme.This patent has novelty, practicality, Meet the requirements, therefore propose patent application in accordance with the law.
