Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the utility model provides a combined steel formwork for ramp bridge anti-collision wall construction, which comprises the following components in an exemplary manner as shown in fig. 1-2: left template 1, right template 2, connecting piece 3. The template is poured in order to solve the anticollision wall that exists among the prior art and adopts the plank sheathing, and the use number of times of plank sheathing is few, the problem that the concrete surface of pouring is not smooth moreover.

Specifically, left template 1, right template 2 in this embodiment adopt the steel sheet to make, fix through connecting piece 3 between the two, compare prior art, have the advantage that the wholeization is stronger, structural component is few, easily dismouting.

Further, as shown in fig. 2 and 3, the left formwork 1 and the right formwork 2 proposed in the present application have the same structure and shape, such as an L-shaped structure, and are butted together to form a cast model of the impact wall, and the specific shape of the cast model can be customized according to actual needs. And the left template 1 and the right template 2 both include: diaphragm 4 and connect the longitudinal plate 5 at diaphragm 4 tip, diaphragm 4 and longitudinal plate 5 are the integration setting, can adopt a whole steel sheet to bend and make, improve the wholeness, do benefit to processing, and bulk strength is high, avoids causing the phenomenon of damage in transportation, use, improves holistic life.

Preferably, in order to improve the connection tightness between the left formwork 1 and the right formwork 2 and prevent leakage during casting, the butt plate 6 is connected to the end of the transverse plate 4, the butt groove 7 matched with the butt plate 6 is opened on the inner side of the longitudinal plate 5, and the sealing member 8 is arranged in the butt groove 7. When the left and

right formworks

1 and 2 are butted, the butt plate 6 is incorporated into the butt groove 7, and the thickness of the butt plate 6 is the same as the depth of the butt groove 7, so that flatness is maintained after the butting. The sealing member 8 seals gaps between the sealing member and the base plate, and leakage during pouring is avoided.

In addition, the sealing element 8 can adopt sealant or polyurethane foam joint mixture, has the advantage of convenient plugging operation, and can be disassembled without damaging the template.

Further, the above-mentioned connecting member 3 includes: bolt 301, nut 302, and connection plate 303, as shown in fig. 3. Wherein, the bolt 301 is connected to the end of the horizontal plate 4, the connecting plate 303 is located outside the vertical plate 5, and the bolt 301 penetrates through the vertical plate 5 and the connecting plate 303. The connecting plate 303 is provided with a through hole matched with the bolt 301.

Through bolt 301, nut 302 and connecting plate 303 with left template 1 and right template 2 fixed together, conveniently adjust the compactness that both go on, simultaneously, also facilitate when the butt joint for when placing left template 1 and right template 2, do not need too accurate location between the two, after placing subaerial, can carry out the accurate butt joint again through bolt 301, nut 302, do benefit to and improve packaging efficiency.

In order to further improve the assembly efficiency, as shown in fig. 4 and 5, in this embodiment, a strip-shaped groove 401 matched with the bolt 301 is formed at the end of the transverse plate 4, the bolt 301 is rotatably connected inside the strip-shaped groove 401, and in a normal state, the bolt 301 can be hidden in the strip-shaped groove 401 under the action of gravity, so that the situation that the bolt 301 is collided when the left formwork 1 and the right formwork 2 are placed is avoided. And the surface of the vertical plate 5 is provided with a strip-shaped hole 501, the end part of the bolt 301 is fixedly connected with a rotating rod 304, the inner side of the strip-shaped groove 401 is provided with a rotating hole 305 matched with the rotating rod 304, and the rotating rod 304 is movably connected inside the rotating hole 305.

Specifically, after the left template 1 and the right template 2 are placed, the bolt 301 is lifted through the strip-shaped hole 501 and penetrates through the strip-shaped hole 501, then the through hole in the connecting plate 303 is sleeved on the bolt 301, then the nut 302 is screwed, and the left template 1 and the right template 2 can be connected together. After the casting of the anti-collision wall is completed, the nuts 302 are sequentially loosened, and the left template 1 and the right template 2 are separated. The disassembly and assembly that can carry out relapse utilizes and not fragile for the surface of anticollision wall is more smooth, has practiced thrift ligneous use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
