Description

A kind of steel work arch bridge

Technical field

The utility model relates to arch bridge, in particular a kind of steel work arch bridge.

Background technology

The construction of existing arch bridge is mainly inwardly progressively to be increased and set up the bow member that steel form arch by bank in river course, and the safety of this construction method is not high, and can greatly affect efficiency of construction; The arch bridge shape radian that method causes thus is in addition level and smooth not, easily produces error, can not form arch comparatively accurately, and construction precision is not high.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can improve efficiency of construction, and work progress is more safe and reliable, and precision is steel work arch bridge more accurately.

For achieving the above object, technical solution of the present utility model is: a kind of steel work arch bridge, mainly from arranging the steelframe parallel arranged of arch more and forming toward steelframe placing of concrete, described steelframe is to be spliced along arch trend by a plurality of holder casees, what the cross section of described holder case was upper base than lower bottom width is trapezoidal, described holder case is divided into a plurality of spaces by spaced diaphragm, and described space is in-built mechanical box.

Preferably, described holder case upper base length is 60cm, and the length of going to the bottom is 50cm.

Preferably, described holder case bottom is provided with fixing otic placode, and two holder casees that same steelframe is adjacent are through its corresponding otic placode, to be connected and fixed respectively by screw.

Preferably, the wallboard of the described holder case left and right sides all has screw.

Preferably, the inner bay of described mechanical box is provided with crisscross steel plate.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: steel work arch bridge of the present utility model is mainly to form toward bow member placing of concrete from arranging the steelframe parallel arranged of arch more and forming bow member, wherein steelframe is to be spliced along arch trend by a plurality of holder casees, and the plane of structure of described holder case is trapezoidal.The steelframe of this structure on land direct splicing forms, then is suspended to river course and is installed and fix by suspender, can improve efficiency of construction, and work progress is safer; The steelframe that steelframe adopts the holder case of the wider isosceles trapezoid of upper base to be located by connecting and to overarch, structure is more stable, and the radian of arc is more level and smooth.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As shown in Figure 1, a kind of steel work arch bridge, is be mainly in parallel arranged to form the bow member (not shown) of one and formed toward bow member placing of concrete from the steelframe 1 of arranging arch more.Wherein steelframe 1 is to be directly spliced on land along arch trend by a plurality of holder casees 2, then is sling and be arranged on river course by suspender, adopts which efficiency of constructing more to increase, and safer, particularly length is 30 meters of above arch bridges, and effect is more obvious.

Described holder case 2(Fig. 2) be the supreme top box body of being cast by steel, what its cross section was upper base than lower bottom width is trapezoidal, for example: upper base length 60cm, the length of going to the bottom 50cm, it is the steelframe 1 of 50m that 110 trapezoidal holder casees 2 are spliced to form both ends horizontal distance, arch bow member 1 structure of trapezoidal holder case 2 location combinations is more stable, and radian is more level and smooth.The diaphragm 22 that holder case 2 inside are spaced apart setting is divided into a plurality of spaces 21, and mechanical box 3 is all equipped with in described space 21; In mechanical box 3, be covered with crisscross steel plate 31, mechanical box 3 can increase the compressive strength of holder case 2.Mechanical box 3 has Single Mechanical case 3 ' (Fig. 3) and double-mechanical case 3 " (Fig. 4) two kinds, double-mechanical case 3 " be with junction plate 4, two Single Mechanical casees 3 ' to be fixed together.Holder case 2 bottoms are provided with otic placode 23, and two the holder casees 2 adjacent at same steelframe 1 are through its corresponding otic placode 23, to be connected and fixed respectively by screw (not shown).Wallboard in holder case 2 left and right sides also all has screw 24 in addition.

The specific embodiment of the present utility model: a plurality of holder casees 2 are stitched together and form the steelframe 1 of arch, wherein hold in the palm between two between case 2 and be fixed together by bottom otic placode 23, guarantee that steelframe 1 overall structure is solid and reliable, also with screw (not shown), wear screw 24 in adjacent two holder case 2 two side wall panels and fix connection.The arch-shaped steel frame 1 use suspender that splicing is completed is lifted on river course, lift again second arch-shaped steel frame 1, and then the screw (not shown) on dismounting holder case 2, pack space 21 into mechanical box 3, what wherein between two row's steelframes 1, placed in adjacent two spaces 21 is double-mechanical case 3 "; preferred; along arch, to move towards to calculate every 5 spaces 21 a double-mechanical case 3 is installed ", all the other spaces 21 are all to place Single Mechanical case 3 ', effectively increase work efficiency and guarantee that two steelframes 1 are to be closely stitched together.By that analogy, continue to lift steelframe 1 on river course, and mechanical box 3 is installed, until form a realistic bow member that requires the all-in-one-piece structure of width.

Above-described, be only preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
