Abstract
The utility model discloses an inverted triangular support of a cast-in-situ box girder, which is characterized in that a concrete strip foundation on a bearing table is taken as a fulcrum, the inverted triangular support is arranged on the concrete strip foundation, and the inverted triangular support comprises an upright main pillar, inclined struts at the left and right sides and a longitudinal girder. The inverted triangular support of the cast-in-situ box girder has the advantages that the bearing capacity is strong, the number of the supports is reduced, the material is saved, the manufacturing procedure can be greatly simplified, the construction is fast and convenient, and the construction period can be shortened.
Description
Technical field
The present invention relates to cast-in-place box beam bracket, in a kind of construction that is applied in the case beam of more specifically saying so, be used to support the support of formwork for placing.
Background technology
In China, classification of rail not only has I level, II level and III level at present, and also having speed per hour is 200 to 350km/h " Lines for Passenger Transportation ", is referred to as Line for Passenger Transportation based on the speed rail of passenger traffic.Line for Passenger Transportation is support with high speed and rapid technology, and train running speed has been realized historical leap.The Line for Passenger Transportation freight volume is big, usefulness is high, and economic results in society are remarkable.
Each grade railway, especially Line for Passenger Transportation circuit major part is made up of bridge, the case beam is the main ingredient of bridge, the case beam is divided into cast-in-situ box girder and prefabricated case beam, wherein cast-in-situ box girder is by rigging at the scene, carry out concrete building then, support plays a part support shuttering, is the indispensable tooling device of cast-in-situ box girder.
At present, cast-in-place box beam bracket adopts netted support more, as full hall formula bowl button support.There is following problem in practice in this form of structure:
1, structure is too complicated, and construction is inconvenient, consumes man-hour.
2, consume material is more, cost of idleness.
4, netted stability of structure is not very high.
3, netted support be erected at whole beam below, when between two cushion caps, setting up, consider the ground situation, need to handle ground.
4, when beam intersects with main traffic main artery, netted support will be blocked the traffic between two cushion caps after setting up, bring inconvenience.
The utility model content
The utility model is for avoiding the deficiency of netted support in the above-mentioned prior art, provide a kind of ability to bear stronger cast-in-situ box girder inverted triangle support, expending to solve ground problem, simplification work progress, saving material and minimizing.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model cast-in-situ box girder inverted triangle support is to be fulcrum with the concrete bar shaped basis on the cushion cap, on concrete bar shaped basis the inverted triangle support is set, and the inverted triangle support is to constitute by being the upright main pillar and the diagonal brace and the longeron of left and right sides.
The design feature of the utility model cast-in-situ box girder inverted triangle support also is:
Described main pillar is the cylinder steel column, and described left and right sides diagonal brace is the Two bors d's oeuveres channel-section steel, described longeron Two bors d's oeuveres i iron.
The bottom of described main pillar and left and right sides diagonal brace is built and is fixed on the concrete bar shaped basis, and the welded top of the bottom of described main pillar and left and right sides diagonal brace is on longeron.
On the concrete bar shaped basis on the same cushion cap, the distributed architecture of overlooking of described inverted triangle support is: with the bridge pier be central distribution on four square position of rectangle, one side of described rectangle is parallel with case beam width direction.
Compare with netted support, the utility model beneficial effect is embodied in:
1, the utility model is simple in structure, easy construction, reduction of erection time.
2, the utility model economical with materials, steel structure material is reusable, saves cost.
3, the utility model uses the inverted triangle structure, and structural stability is strengthened.
4, the utility model inverted triangle support directly is erected on the cushion cap, need not ground between two cushion caps is handled.
5, the utility model inverted triangle support can not blocked the traffic between two cushion caps.
6, it is less that the utility model inverted triangle support is particularly useful for the pier height, the cast-in-place construction of the case beam of pier spacing about 10 meters.
Description of drawings
Fig. 1 is the utility model vertical structure schematic diagram.
Fig. 2 is the utility model cross-sectional configuration schematic diagram.
Number in the figure: 1 main pillar, 2 left and right sides diagonal braces, 3 longerons, 4 concrete bar shaped bases, 5 bridge piers, 6 cushion caps.
The specific embodiment
Referring to Fig. 1, Fig. 2, it is fulcrum that the structure of present embodiment is set to the concrete bar shaped basis 4 on the cushion cap 6, on concrete bar shaped basis 4 the inverted triangle support is set, and the inverted triangle support is to constitute by being the upright main pillar 1 and the diagonal brace 2 and the longeron 3 of left and right sides.
In concrete the enforcement, main pillar 1 is the cylinder steel column, and left and right sides diagonal brace 2 is the Two bors d's oeuveres channel-section steel.The bottom of main pillar 1, left and right sides diagonal brace 2 is built and is fixed on the concrete bar shaped basis 4, in advance the steel work of each post is partly welded together during construction, by being mechanically anchored on the corresponding position, carry out concreting again, the degree of depth that frame bottom is submerged in the concrete should reach 780mm; The welded top of main pillar 1, left and right sides diagonal brace 2 is on longeron 3.
Referring to Fig. 2, in the present embodiment, on same concrete bearing platform 6, the distributed architecture of overlooking of described inverted triangle support is: with bridge pier 5 is that central distribution is on four square position of rectangle, one side of described rectangle is parallel with case beam width direction, wherein, along being 4820mm to middle distance between two groups of inverted triangles of case beam length direction.
