Abstract
The utility model relates to a duplex beam for bridge construction. The duplex beam for bridge construction is characterized in that four steel plates are welded together to form the duplex beam. The four steel plates are respectively a roof, a floor and two web plates. The roof is parallel to the floor and the web plates are vertical to the roof. The width of the floor is not bigger than that of the roof. The distance of the two web plates is 0.4-0.8 times of the width of the roof. A plurality of holes are installed on the corresponding positions of the roof and the floor. The duplex beam for bridge construction is in simple structure with four steel plates welded together. The duplex beam for bridge construction lifted at the bottom of the bridge body can support the beam, and thus can used for maintenance of the bridge. The duplex beam can be demolished by releasing a hoisted rope or other suspended equipment. The duplex beam for bridge construction is practical and simple. The hanging point is located in the holes of the duplex beam, thereby avoiding direct effect on the beam.
Description
Technical field
The utility model relates to bridge site operation, inspection, maintenance frock making field, especially, relates to a kind of duplexing ellbeam for bridge construction.
Background technology
The inside and outside bridge quantity in city gets more and more at present.These bridges are when offering convenience to people's trip, and Partial Bridges is partially long because of the construction time, or cause the gradually damage of bridge construction because of the reason that designs, construct; For guaranteeing the current safety of people, must make regular check on and keep in repair bridge.
The job site of inspection and maintenance, can take following two kinds of methods: 1, Support Method: jack acts directly on beam body bottom and carries out lifting operation; 2, Hanging Basket method: utilize Suspenoing apparatus, the segmented beam body that carries out promotes operation.These two kinds of methods respectively have drawback, and the jack structure that Support Method utilizes is complicated, and cost is high; And Hanging Basket method structure complex procedures, and be difficult to control repair quality.
The utility model content
The utility model purpose is to provide a kind of duplexing ellbeam for bridge construction, to solve the too complicated technical problem of existing bridge maintenance device structure.
For achieving the above object, the utility model provides a kind of duplexing ellbeam for bridge construction, it is characterized in that, is that four block plates are welded, and is respectively top board, base plate and two blocks of webs; Described top board is parallel with described base plate, and described web is vertical with described top board, and described baseplate width is not more than the width of described top board, the distance between two blocks of webs be described top board width 0.4-0.8 doubly; On the relevant position of top board and base plate, some holes are set.
Preferably, the height of described web be the top board width 1-1.5 doubly.
Preferably, described web outside arranges some ribs, and described ribs is perpendicular to described web and described top board.
Preferably, near the described ribs interval of described top board central authorities greater than the described ribs near described top board two ends.
Preferably, the quantity of described hole is 2.
Preferably, the center of circle of described hole is positioned on described ribs and the line that described top board is connected.
Preferably, described hole is arranged on the relevant position of the top board that is positioned at described web inboard and base plate, and the described hole diameter is less than the distance between described two blocks of webs.
The utlity model has following beneficial effect:
1, it is convenient to make, install and remove: the application is simple for structure, is got final product by the welding of four block plates; It is lifted on the bridge beam body bottom, can supports the beam body, thereby bridge is overhauled; Rope or other Suspenoing apparatus of lifting are unclamped i.e. dismountable the application duplex ellbeam, practical simplicity;
2, protection beam body safety: the suspension centre of lifting is positioned at the hole place on the duplexing ellbeam, then hanging device is by to the effect of duplexing ellbeam and with its brace summer body of slinging, avoid suspension centre to act directly on Liang Tishang, make the beam body produce excessive stress at suspension centre, damage the beam body;
3, supporting capacity is high: structure is become by Plate Welding entirely, can carry the above beam body of 800T.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the overall structure schematic perspective view of the utility model preferred embodiment;
Fig. 2 is the ribs structural upright schematic diagram of the utility model preferred embodiment;
Wherein, 1, top board, 2, base plate, 3, web, 4, hole, 5, ribs.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the utility model can be implemented according to the multitude of different ways that claim limits and covers.
Referring to Fig. 1 and Fig. 2, a kind of duplexing ellbeam for bridge construction is that four block plates are welded, and is respectively top board 1, base plate 2 and two blocks of webs 3; Described top board 1 is parallel with described base plate 2, and described web 3 is vertical with described top board 1, and described base plate 2 width are not more than the width of described top board 1, the distance that two blocks of webs are 3 be described top board 1 width 0.4-0.8 doubly, stressed comparatively even; On the relevant position of top board 1 and base plate 2, some holes 4 are set, be used for passing the rope whole duplexing ellbeam of slinging.The quantity of hole 4 can be 2, is distributed in top board 1 and base plate 2 two ends.
In addition, the height of described web 3 can be top board 1 width 1-1.5 doubly; Share, spread the beam body weight power that descends from top board 1 with long web 3.
Described web 3 outsides can arrange some ribs 5, and described ribs 5 is perpendicular to described web 3 and described top board 1.Vertical ribs 5 can disperse top board 1 to the pressure of web 3.
Described ribs 5 intervals near described top board 1 central authorities can be greater than the described ribs 5 near described top board 1 two ends; Referring to Fig. 2, the spacing between ribs B and the D is greater than the spacing between the AB, also greater than the spacing between the CD.The ribs at two ends is more intensive, and then the probability of duplexing ellbeam edge deformation reduces many.
The center of circle of hole 4 can be positioned on described ribs 5 and the line that described top board 1 is connected, then hole 4 edge stress is distributed on the ribs 5, and security performance is better.
Described hole 4 can be arranged on the relevant position of the top board 1 that is positioned at described web 3 inboards and base plate 2, and described hole 4 diameters are less than the distance of 3 of described two blocks of webs, does not affect the bonding strength of web 3 and top board 1.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
