TECHNICAL FIELD
[0001] The utility model relates to the field of building construction engineering, and specifically relates to a prefabricated box girder diaphragm plate formwork device with adjustable angle. BACKGROUND
[0002] In bridge engineering construction, as a common structure form, the angle precision of the diaphragm plate of the prefabricated box girder is crucial to the overall quality and stability of the bridge. Especially when the bridge is located on a horizontal curve, since the diaphragm plate angle of each prefabricated box girder is different, the traditional construction method is to process a set of formwork for each angle of the diaphragm plate. However, this method has many shortcomings:
[0003] Firstly, processing the diaphragm plate formwork of each angle separately not only increases the number of formwork processing, but also increases the construction cost. At the same time, since the number of formwork is large, management and storage become a problem, which easily causes damage and loss of the formwork.
[0004] Secondly, the traditional construction method has high precision requirements for the formwork. Once the formwork processing has errors, it will cause the diaphragm plate angle to deviate from the design angle. This deviation may not be obvious on a single box girder, but when multiple box girders are spliced together, it will accumulate into a large error, seriously affecting the appearance and overall quality of the bridge.
[0005] In addition, for some diaphragm plates with small angle deviation, the traditional construction method may choose a compromise solution, that is, using a formwork of a certain fixed angle for construction. However, this method reduces the number of formwork, but sacrifices the angle precision of the diaphragm plate, causing the diaphragm plate between two box girders to be misaligned after the girder plate is installed, which not only affects the appearance, but also may pose a threat to the structural safety of the bridge.
[0006] When the bridge engineering is located on a horizontal curve, the diaphragm plate angle of each prefabricated box girder is different. If a set of formwork is processed for each angle diaphragm plate during box girder prefabrication, the construction cost is high. During actual construction, most projects will process a formwork of a certain fixed angle, and the diaphragm plates within a deviation range of ±2° will use this formwork. This construction method will cause the diaphragm plate angle to deviate from the design angle, and will cause the diaphragm plate between two box girders to not be on the same straight line after the girder plate is installed, affecting the appearance of the bridge and the quality of the completed bridge.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.
[0030] like Figures 1-7 As shown: An angle-adjustable precast box girder transverse diaphragm template device includes a web template 1 and a transverse diaphragm template 2, wherein the transverse diaphragm template and the box girder web template are connected by a hinge 5.
[0031] The web formwork 1 includes a panel 3, back ribs 4, and tie beams 5. The panel is made of 6mm thick steel plate, the back ribs are made of No. 10 channel steel, and the tie beams are made of No. 12 channel steel to enhance the overall strength and stability of the formwork.
[0032] The diaphragm template includes a panel 3 and a back rib 4. The panel is made of 6mm thick steel plate, and the back rib is made of No. 10 channel steel to accommodate diaphragms at different angles.
[0033] The hinge 5 is made of 20mm thick steel plate 6, with a pin 7 between the thick steel plates. The pin diameter is 15mm. One end of the hinge is fixedly connected to the back rib of the diaphragm template, and the other end is movably connected to the back rib of the web template, so that the diaphragm template can be angled relative to the web template.
[0034] A 28mm diameter screw 8 is also installed between the diaphragm template and the web template as an adjustment rod. By rotating the adjustment rod, the angle of the diaphragm template can be further fine-tuned to ensure that it is consistent with the design angle.
[0035] It also includes an adjustment block 9, which includes a first steel plate 91, a second steel plate 92 and a third steel plate 93, all of which are 6mm thick steel plates and are all set at the back rib of the transverse partition template by magnets.
[0036] Because the bottom of the box girder top slab is zigzag-shaped, the diagonal length of the diaphragm formwork will change accordingly after the angle of the diaphragm formwork is adjusted. Therefore, movable steel plate adjustment blocks are installed at the back ribs of the diaphragm formwork. These adjustment blocks are all made of 6mm thick steel plates. When the angle of the diaphragm formwork changes, the dimensions of these steel plates need to be adjusted, and they are fixed to the back ribs of the formwork with magnets to maintain the stability of the diaphragm formwork.
[0037] First, the web plate template and the transverse plate template are made, then the hinges and the adjusting rods are installed, so that the transverse plate template can be adjusted in angle relative to the web plate template. Finally, the adjusting blocks are installed to adapt to the needs of different angle transverse plates. Through the device of the application, the angle of the transverse plate can be accurately adjusted, the construction quality and efficiency are improved, and the construction cost is reduced.
[0038] The above are only embodiments provided by the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, but any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
