Detailed Description
The steel structure web for bridge engineering comprises at least one continuously bent web 10 and wing plates 20 at the upper and lower ends of the web, and generally, the wing plates are welded on the web.
Because the span of the steel structure web in the length direction of the bridge is large, the bending resistance of the steel structure web in the length direction needs to be fully considered, and the characteristic of poor bending resistance of the web in the length direction is adopted, the embodiment improves the steel structure web, and the bending resistance of the steel structure web and the bonding strength of the steel structure web and concrete are improved.
Example one
Referring to fig. 1 and 5, the web 10 is formed by continuously bending a thick steel plate to form a continuous "︺" shape, which is also a common web structure, and the web of the structure is easily bent at the bending position of the metal plate, that is, the horizontal direction of the web is an easy-bending direction. For example, a 2 mm thick steel plate is continuously bent by a bending machine, and the continuous bending can improve the bending resistance of the web in the height direction, which is beneficial, but can also weaken the capability in the length direction of the bridge, namely, the capability of being easily bent in the horizontal direction, which is a negative factor, so that the steel plates are welded at the upper end and the lower end of the web 10 to form the wing plate 20, and the wing plate is of a non-centered design, namely, the exposed size of the outer side of the wing plate is smaller than that of the inner side. The existence of the wing plate can supplement the weak point of the web plate in the length direction of the bridge, so that the whole bridge has certain bending resistance. The inner side in the present embodiment refers to a side of the cast concrete adjacent to the side of the concrete 00. Holes are continuously punched on the wing plates 20 at positions close to the inner side edges, reinforcing steel bars 21 are inserted, and the upper and lower ends of the reinforcing steel bars 21 are fixed and welded on the upper wing plates and the lower wing plates. Therefore, the steel bars 21 are uniformly and parallelly arranged on the inner side of the web plate, a structure with a three-dimensional space is constructed by the steel bars, the web plate and the wing plates, and the overall tensile strength and bending strength of the steel structure web plate are improved under the action of the steel bars.
Further, the above-mentioned reinforcing bars 21 are preferably disposed in the bending recesses 11 of the web 10, and the stability of the structure is optimized.
Generally, the reinforcing bars 21 are welded to the flanges.
In this embodiment, the reinforcing bars 21 have two functions, and the existence of the reinforcing bars can enhance the overall strength of the steel structural web before concrete pouring. In the concrete pouring process, the local deformation of the web caused by the self weight and the external expansion force of the concrete is avoided. The second function is that after the concrete is solidified, the steel bar and the concrete are firmly combined, and the bonding strength of the web plate is improved.
The angle steel 22 and the auxiliary bar 23 are welded on the upper wing plate and the lower wing plate respectively, wherein the angle steel 22 is arranged along the length direction of the web plate and is welded and fixed, and the U-shaped reinforcing bar 23 is welded on the angle steel 22 to form the auxiliary bar which is used for being fully connected with the pouring body.
Connecting pieces 24 are arranged at the end parts of the two ends of the upper wing plate and the lower wing plate in the length direction and used for connecting the two adjacent steel structure wing plates, and bolt holes are formed in the connecting pieces.
Further, bolt holes are also provided at the ends of the wing plates.
The steel structure web is integrally subjected to galvanizing antiseptic treatment to form an antiseptic member with good performance, and long-term maintenance-free.
Referring to fig. 2, a connector 30 for connecting steel structural webs between adjacent panels, specifically, the connector comprises a flat plate 31, two risers 32 and a reinforcing rib 33, wherein the flat plate is provided with two pairs of four bolt holes, and the four bolt holes are connected with bolt holes on two flanges in a matching manner. A pair of bolt holes is also arranged on the vertical plates, each vertical plate corresponds to one connecting piece and is connected by using bolts, and refer to fig. 3.
In this structure implementation, only need use the spanner can carry out quick assembled construction, avoid on-the-spot welding operation, convenient and fast.
The application example of the steel structure web in bridge engineering is as follows:
arranging a plurality of steel structure webs along the bridge direction in sequence, connecting the two adjacent steel structure webs by using a connecting piece 30 and a bolt 40, pouring concrete by matching a template on the inner side of each steel structure web, and forming a bridge main body after hardening. In this embodiment, there are reinforcing bars 21, make the complete embedding of back reinforcing bar after pouring in concrete 00 structure, form the secondary and connect, improved the fusibility of steel construction web and bridge greatly, refer to fig. 4.
In this embodiment, the steel bar is preferably a deformed steel bar.
Example two
The present embodiment is directed to an improvement of a local structure of a web, and as described above, a plurality of parallel sheet metal bending lines are present on the web, specifically, in the present embodiment, a plurality of local ribs 13 are formed at the sheet metal bending lines 12 of the web 10 by means of local stamping, the ribs are formed by using an over-stamping die, and the existence of the above ribs enables the above web to have a certain bending resistance in a horizontal length direction, which is only a certain improvement compared with the first embodiment.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should be able to make various modifications and improvements to the present invention without departing from the spirit of the present invention.
