Abstract

The invention relates to a corrugated steel web box beam with steel-concrete composite plate bottom flange, in particular to a corrugated steel web box beam that is applied in railway and bridges. The corrugated steel web box beam is composed of a top flange concrete slab, a corrugated steel web and a steel-concrete composite plate bottom flange, wherein steel-concrete composite plate is composed of a slotted steel plate formed by side plates and bottom plates, and a concrete, the steel plate is welded with bolts and reinforced meshes are arranged at middle position of the concrete. The structure can overcome the problem that the traditional corrugated steel web box beam has complicated construction for steel structure positioning on the spot, and also can exert tensile strength of the steel plate so as to improve crack resistance of structure effectively and avoid crack from being exposed, so that structural endurance is improved obviously, therefore the work load and difficulty of the construction of concrete in-field casting of box beam bottom flange is reduced greatly. The corrugated steel web box beam with steel-concrete composite plate bottom flange has simple structure, rapid and convenient construction and is easy to meet the requirement of planar shape of bridge, and also has good technical economic benefit.

Description

Corrugated steel web case beam with steel-concrete combined board lower wing edges
Technical field
The present invention relates to a kind of corrugated steel web case beam that can be applicable to railroad bridge and highway bridge with steel-concrete combined board lower wing edges; Belong to the bridge construction technical field.
Background technology
Traditional corrugated steel web concrete combined box beam, shown in Fig. 1 (a), 1 (b), it is made up of top flange concrete slab 1, the vertical or tilted-putted corrugated steel web with two of bottom flange concrete slab 2, the steel plate on each the limb corrugated steel web and the upper and lower edge of a wing is with after factory welding is transported to the job site, need accurately locate, difficulty of construction is big.When the bottom flange concrete slab was built, scaffold, a template etc. were set up in the scene of need, have problems such as field operation and difficulty of construction are bigger.On the other hand, cracking appears in bottom flange concrete slab easily under the positive bending moment effect, and the crack can reduce bearing capacity, rigidity and the durability of structure.These problems have caused certain difficulty all for applying of this class formation.
Summary of the invention
The purpose of this invention is to provide that a kind of field operation amount and difficulty of construction are less with respect to traditional corrugated steel web box girder, the corrugated steel web case beam that structural bearing capacity, rigidity and cracking resistance are higher with steel-concrete combined board lower wing edges.
Technical scheme of the present invention is as follows:
A kind of corrugated steel web case beam with steel-concrete combined board lower wing edges, form by top flange concrete slab, the vertical or corrugated steel web that tilts and the steel-concrete combined board of bottom flange, it is characterized in that: described steel-concrete combined board by melting welding the troughing plate of peg and the concrete that is cast in troughing plate inside form, be provided with reinforced mesh at described concrete medium position; Described troughing plate is made up of side plate and base plate.
Technical characterictic of the present invention also is: described troughing plate is made up of side plate and base plate, and side plate can vertically or tilt to place, and the peg on side plate and the base plate can adopt rectangular mesh shape or quincuncial arrangement.
The present invention has the following advantages with respect to prior art:
1. after corrugated steel web case lower flange of girder edge adopted steel-concrete combined board, location, the welding job of steel work part were all finished in factory, can overcome the construction complexity that the conventional boxes beam need position, install corrugated steel web at the scene.Batch production degree height of the present invention, environmental effect are good.Steel work partly is mainly prefabrication, and quality is easy to guarantee.2. case lower flange of girder edge adopts steel-concrete combined board, can reduce the scene greatly and set up scaffold, formwork, concrete wet trade workload and difficulty of construction, can shorten construction period, accelerating construction progress.Traffic under the bridge cut-off in can be during construction; Quick construction, overall economic efficiency is good, is concrete very big improvement is adopted in traditional corrugated steel web box girder bottom flange.3. steel-concrete combined board form of structure is reasonable, can give full play to the good characteristics of steel tensile property, can effectively improve the crack resistance of structure, avoids the crack to expose etc., and durability of structures can significantly improve.4. bottom wing balsh-concrete combined board has reduced form work engineering and a concrete wet trade workload and a die process of top flange for building of case beam top flange concrete slab provides support, reduces the site work amount.

The specific embodiment
Below in conjunction with accompanying drawing, structure of the present invention, work progress are further described.
The invention provides and to reduce field operation amount and difficulty of construction, and improve the corrugated steel web case beam with steel-concrete combined board lower wing edges of structural bearing capacity, rigidity and cracking resistance.As Fig. 2~shown in Figure 5, the case beam is made up of the steel-concrete combined board 6 of top flange concrete slab 1, corrugated steel web 3 and bottom flange.Steel-concrete combined board 6 by melting welding the troughing plate of peg 5 and the concrete 10 that is cast in troughing plate inside form, be provided with reinforced mesh 9 at the medium position of described concrete 10; Described troughing plate is made up of side plate 7 and base plate 8.Side plate can vertically or tilt to place, and the peg on side plate and the base plate can adopt rectangular mesh shape or quincuncial arrangement.
Working procedure of the present invention is:
The working procedure of the corrugated steel web case beam with steel-concrete combined board lower wing edges of the present invention is by the splicing of steel work, and three parts of building of bottom wing balsh-concrete combined board and top flange concrete slab are formed.In factory base plate 8 and side plate 7 are formed troughing plate, with corrugated steel web 3 and steel plate 4, base plate 8 welding (corrugated steel webs 3 and side plate 7 tiltables or vertical placement, as shown in Fig. 2 (a) and (b)), difference melting welding peg 5 on steel plate 4, base plate 8 and side plate 7, after the steel member is transported to the job site, carry out the making (is that example describes with Fig. 2 (a)) of bottom wing balsh-concrete combined board 6.Its preparation method is as follows: concreting 10 between the biside plate 7 of the base plate 8 of the good peg 5 of melting welding, be combined into one with steel plate, and the medium position of concrete 10 is arranged the reinforced mesh 9 of some, forms steel-concrete combined board as shown in Figure 4.After treating that concrete 10 reaches certain intensity, formwork as top flange concrete slab 1 provides interim support, or the steel plate 4 in the top flange connects interim angle steel and is used for a template, and a top flange template, assembling reinforcement, concreting have formed corrugated steel web case beam as shown in Figure 2.
