The invention improves the traditional outer template 1 of the anti-collision wall, and the inner template still adopts the traditional inner template. The outer wall of the outer template 1 of the traditional anti-collision wall is provided with stiffening ribs, and the inner wall of the outer template 1 is smooth, while the outer wall of the outer template 1 of the invention is smooth, preferably, the outer template 1 is a steel plate with smooth outer wall and thickness of 4-8mm, and the stiffening ribs are additionally arranged on the inner wall of the outer template 1.
The stiffening ribs comprise longitudinal ribs 2 and transverse ribs 3, wherein a trapezoidal framework is welded on the longitudinal ribs 2 at intervals and is used for enhancing the supporting strength of the outer template 1. The trapezoid frameworks are arranged along the length direction of the outer template 1, preferably one framework is arranged every 2-3 m. Each concrete trapezoidal skeleton includes that the rib 2 is indulged to one, indulges on the rib 2 from last to a plurality of short steel sheet 4 of horizontal welding down on this way, and the other end of short steel sheet 4 all welds on an oblique steel sheet 5, and short steel sheet 4 increases down length from last in proper order, finally indulges rib 2, short steel sheet 4 and oblique steel sheet 5 and constitutes a trapezoidal shape, is the trapezoidal skeleton of this application. The preferred short steel plate 4 and the oblique steel plate 5 have a thickness of between 5 and 8mm and a width of between 5 and 6 cm.
In the invention, nuts 6 are welded on the inner wall of the outer template 1, each nut 6 corresponds to the position of a bolt hole for connection on the inner template matched with the outer template 1, and during connection, a screw rod penetrates through the bolt hole of the inner template and then is connected in the nut 6 of the outer template 1 in a threaded manner. Nut 6 positions on 1 inner wall of outer mould board correspond with the bolt hole of traditional inner mould board, can form a complete set and circulate traditional inner mould board like this, avoid the waste of inner mould board. In order to enable the screw rod to be repeatedly used, a plastic sleeve is sleeved on the screw rod between the inner wall of the outer template 1 and the inner wall of the inner template, and the diameter of the plastic sleeve is slightly larger than that of the screw rod and is sleeved on the screw rod. After the concrete is poured, the screw rod can still be taken out.
A connecting channel steel 7 is integrally arranged at the bottom of the outer template 1, the connecting channel steel 7 is used for being welded on a steel box girder wing plate 8, the connecting channel steel 7 is closely attached to the steel box girder wing plate 8 for welding, so that the outer template 1 and the steel box girder are connected into a whole, and the problem of slurry leakage at the bottom corner of the outer template 1 is avoided.
For preventing that rainwater down-flow from corroding steel box girder bottom, the preferred vertical downward body coupling in 1 outer wall of exterior sheathing of this embodiment extends steel sheet 9, and the bottom height of the extension steel sheet 9 of body coupling will be less than the bottom height of the steel box girder side that closes on, and the bottom that extends steel sheet 9 is located the below of the steel box girder side bottom that closes on promptly, and like this, the rainwater can flow down along extending steel sheet 9, can not flow on the steel box girder.
In order to make the bottom of the whole constructed anti-collision wall look beautiful and full, preferably, a combination steel plate 10 is arranged between the bottom of the extension steel plate 9 and the bottom of the steel box girder, and the combination steel plate 10 connects the bottom of the extension steel plate 9 and the bottom of the side surface of the steel box girder. The anti-collision wall is integrally observed, and a gap seen visually cannot appear, so that the attractiveness of the whole anti-collision wall is affected. In this embodiment, combine the preferred right angle steel sheet that is of steel sheet 10, the steel sheet 9 bottoms of extending are connected to the right angle steel sheet horizontal plane, and the vertical face of right angle steel sheet extends to the bottom of the steel box girder side that closes on, and the vertical face of right angle steel sheet need not the welding in the bottom of steel box girder side, only need with the bottom contact of steel box girder side can.
In order to make the whole anti-collision wall more beautiful, the outer wall of the outer template 1 is preferably sprayed with the concrete color antirust paint, so that the color tone is coordinated with surrounding structures, and the visual effect is better.
When the anti-collision outer formwork is used, the outer formwork 1 is firstly processed in a factory in a unified mode, before a steel box girder is hoisted, the connecting channel steel 7 of the outer formwork 1 is welded on a wing plate of the steel box girder, welding seams are full during welding, bottom slurry leakage is avoided, then concrete color anti-rust paint is sprayed on the outer wall of the outer formwork 1, then the whole steel box girder and the outer formwork 1 are hoisted, after the hoisting is completed, the inner formwork and the outer formwork 1 are connected and fixed together, a screw rod penetrates through a bolt hole of the inner formwork and then is connected into a nut 6 on the inner wall of the outer formwork 1, after the inner formwork and the outer formwork 1 are connected, concrete is poured, when the concrete reaches the designed strength, the inner formwork is removed, when the inner formwork is removed, the screw rod is unscrewed, the inner formwork and the screw rod are taken out, the outer formwork 1 is reserved as a part of.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
