AI Technical Summary
The steel side mold used in traditional box girder pouring is an integral rigid mold, and the prefabricated box girder wing plate molding angle and box girder height cannot be adjusted, resulting in the need to prepare multiple sets of molds. The mold installation and debugging time is long, the production cost is high, and the resource waste is serious.
A box beam steel formwork with adjustable wing plates is designed, including a middle beam high side mold frame and an outer side mold frame. By setting up adjustment support, positioning pin shaft and side beam wing plate adjustment components, adjustable wing plate angle and box beam height can be achieved.
The rapid adjustment of the angle of the steel side formwork wing plate of the box girder and the height of the box girder is achieved, reducing the need to replace molds when producing concrete components of different box girders, and reducing production costs and resource waste.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete bridge casting molds, and particularly relates to a box girder steel formwork with adjustable wing plates. Background Technique
[0002] In many road and bridge projects, the structural dimensions of box girder precast components in different bridge sections are roughly the same, only the wing plate angle or the box girder height has some changes. The steel side form used for traditional box girder casting is an integral rigid form, which cannot adjust the forming angle of the precast box girder wing plate and the box girder height. Therefore, multiple sets of molds need to be prepared to produce different beam types, resulting in a long mold installation and debugging time, high production costs, and serious waste of resources.
[0003] Therefore, we propose a box girder steel formwork with adjustable wing plates. Content of the Utility Model
[0004] The purpose of the utility model is to provide a box girder steel formwork with adjustable wing plates to solve the problems raised in the above background technique.

A middle beam high side formwork web is arranged on the middle beam high side formwork skeleton, an outer beam wing plate and an outer beam side formwork web are arranged on the outer beam side formwork skeleton, a bottom form is arranged at the bottom of the middle beam high side formwork web and the outer beam side formwork web, a bottom form trolley is arranged at the bottom of the bottom form, and a middle beam high wing plate is arranged at the top of the middle beam high side formwork web.
[0006] Preferably, an adjusting support is arranged at the bottom of the middle beam high wing plate.
[0007] Preferably, a positioning pin shaft and a side beam wing plate adjusting component are arranged between the middle beam high side formwork web and the middle beam high wing plate.
[0008] Preferably, the outer beam wing plate and the outer beam side formwork web are connected through a side beam wing plate adjusting component.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] 1. The wing plate angle of the box girder steel side form of the present invention and the box girder height are adjustable, and there is no need to replace the whole set of molds to produce different box girder concrete components, greatly reducing the production cost.
[0011] 2. The adjustment of the wing plate angle or the box girder height of the box girder steel side form of the present invention is convenient and fast, and there is no need to debug a whole new set of molds, greatly reducing the production cycle. Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: a box girder steel formwork with adjustable flanges, including a high-side formwork skeleton 1 of the middle beam and a side formwork skeleton 2 of the outer beam. A web 3 of the high-side formwork of the middle beam is arranged on the high-side formwork skeleton 1 of the middle beam. A flange 4 of the outer beam and a web 5 of the side formwork of the outer beam are arranged on the side formwork skeleton 2 of the outer beam. A bottom formwork 6 is arranged at the bottoms of the web 3 of the high-side formwork of the middle beam and the web 5 of the side formwork of the outer beam. A bottom formwork trolley 7 is arranged at the bottom of the bottom formwork 6. A high-side flange 8 of the middle beam is arranged at the top of the web 3 of the high-side formwork of the middle beam. After assembly, the side formwork of the side beam forms a rigid whole. According to requirements, the flange adjusting assembly 12 of the side beam and the adjusting support 9 are replaced, and the height and installation angle of the flange part can be quickly adjusted. The size of the flange 8 part of the high-side formwork of the middle beam is relatively small, so the flange 8 part of the high-side formwork of the middle beam and the web 5 part of the side formwork of the outer beam are directly made into two independent parts, and the two are connected by a flange and fastened with bolts. The flatness of the panel at the connection is ensured by installing a positioning pin 11. Similarly, the flange adjusting assembly 12 part of the side beam is connected and fixed to the middle beam formwork skeleton 1 by the adjusting support 9. In this way, the middle beam formwork skeleton 1 forms a rigid whole. By replacing the flange adjusting assembly 12 part of the side beam and the adjusting support 9, the height and installation angle of the flange part can be quickly adjusted. The present invention can realize the production of another beam type on the entire production line only by replacing the flange part or the flange adjusting assembly 12 of the side beam, and can realize the production of multiple beam types without additional complete sets of molds, greatly saving construction time and production costs.
[0018] Reference embodiment: An adjusting support 9 is provided at the bottom of the high-side web plate 8 of the middle beam. A positioning pin shaft 11 and a side beam web plate adjusting assembly 12 are provided between the high-side formwork web plate 3 and the high-side web plate 8 of the middle beam. The outer side beam web plate 4 and the outer side beam formwork web plate 5 are connected by the side beam web plate adjusting assembly 12. Flange plates and bolts are used for connection among the three. The positioning pin shaft 11 is used to ensure that the panel at the connection is flush. Part of the side beam web plate adjusting assembly 12 is fixedly connected to the side beam formwork skeleton through the adjusting support 9.
[0019] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
