Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering bridge prefabrication, and more specifically, to a beam body anchoring template device for a single-box single-chamber equal-height simply supported box beam. Background Art

[0002] In the project targeted by this application, the box girder web is tensioned by a symmetrical single-row steel strand, abandoning the traditional symmetrical two-row steel strand tensioning method, which saves steel strands while also reducing labor intensity; due to the use of a single-row steel strand tensioning method, the anchor model is increased, and the required longitudinal cross-sectional area of ​​the box girder end is also larger. The bottom spacing of the anchor is only 10mm and the top is only 60mm, while the diameter of the groove sealing rubber ring inside the anchor is 35mm, which causes the sealing rubber rings of the two adjacent anchors to "squeeze each other", making it impossible to use traditional formwork for anchor sealing construction. Therefore, this application sets up a new anchor sealing formwork device to perform anchor sealing construction without affecting the anchor pad. Utility Model Content

[0020] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0021] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] This application is applicable to the high-speed railway (Tongqiao 2235) series of simply supported box girders with single-box and single-chamber equal height cross-section types, and the beam body is sealed and anchored using an anchor hole with a matching inner groove.

[0023] like Figures 1 to 4 As shown, the utility model provides a beam body anchoring template device for a single-box single-chamber equal-height simply supported box beam, comprising an anchoring plate 1, which covers a plurality of anchor holes 2, the anchoring plate 1 is fixed by bolt holes on both sides of an anchor pad, and the anchor holes 2 are formed into a sealed space, a discharge port 3 is provided on the anchoring plate 1 corresponding to each anchor hole 2, each discharge port 3 is provided with a clamping groove 4 arranged along the outer periphery of the discharge port 3, which is U-shaped, a steel plate 5 is slidably provided on the clamping groove 4, and the steel plate 5 slides downward along the clamping groove 4 until it fits exactly into the discharge port 3, and the size of the steel plate 5 matches the size of the discharge port 3.

[0024] The anchor plate 1 of the present application is made of a whole piece, and the construction of multiple anchor holes 2 is completed at one time, which can reduce concrete waste and construction time. The setting of the slot 4 can ensure that the concrete at the discharge port 3 has a good flatness that meets the requirements after demolding by inserting the steel plate 5, that is, it can prevent the concrete structure surface from being misaligned after molding. If there is no setting of the slot 4 and the steel plate 5, the misalignment formed needs to be chiseled out after demolding, which increases the extra workload.

[0025] Through design, the present application connects the web ends together without changing the angle and position of the anchor hole 2, and the groove in the anchor pad adopts a full-length sealing rubber strip, which not only meets the on-site construction requirements but also meets the design requirements. When performing the anchor sealing operation, a self-developed template device is used to meet the on-site construction requirements.

[0026] The device of this application is prefabricated with steel formwork, and is developed according to the location of the anchor and the location of the anchor hole on site. A discharge port 3 is reserved at each anchor hole 2, and a steel plate 5 is used to seal the port after the construction work is completed, so as to efficiently complete the beam body anchoring construction. After the beam body is grouted, the anchor mesh is tied at the anchor hole 2 at the end of the beam. After the tying is completed, the homemade anchoring formwork device is installed, and the anchor plate 1 is fixed through the bolt holes on both sides of the anchor pad. The anchoring operation is carried out from the discharge port 3 of the anchor plate 1. The concrete is vibrated by a vibrating rod to achieve a dense effect. After the pouring is completed, the steel plate 5 is inserted into the discharge port 3 through the slot 4 of the anchor plate 1 to remove the excess concrete and ensure the flatness of the anchoring surface after the demolding. Finally, the anchor plate 1 is removed for the surface finishing cycle operation.

[0027] In another technical solution, a plurality of anchor sealing plates 1 are provided, one each on the anchor holes 2 on both sides of the web of the beam body, and a plurality of anchor sealing plates 1 are provided at intervals on the anchor holes 2 at the bottom of the web of the beam body. The anchor holes 2 at the bottom of the web are grouped into multiple groups according to design requirements, and a plurality of anchor sealing plates 1 are provided, while an anchor sealing plate 1 is provided on each side of the web to realize one-time anchor sealing construction.

[0028] In another technical solution, the anchor sealing plates 1 corresponding to the two sides and the bottom of the beam web have multiple discharge ports 3 arranged at the top of the corresponding anchor holes 2 to facilitate the concrete pouring and vibration construction.

[0029] In another technical solution, the openings of the slots 4 are all facing the tops of the corresponding anchor holes 2, so as to facilitate the sliding construction of the steel plates 5 in the slots 4. The safe construction of the steel plates 5 is achieved through the blocking of the slots 4.

[0030] In another technical solution, a lubricating layer is provided on the inner side surface opposite to the slot 4 , which is beneficial to the smooth sliding of the steel plate 5 .

[0031] In another technical solution, a pair of auxiliary plates 6 are provided at the top of the steel plate 5 facing the side of the opening of the slot 4, and extend horizontally outward along the top surface of the steel plate 5. When the steel plate 5 is fitted in the discharge port 3, the pair of auxiliary plates 6 are just set close to the anchor plate 1. When the steel plate 5 is placed in the discharge port 3, if the pressing force is too large or it is tilted, it is easy to make the surface of the concrete structure after forming uneven, misaligned or tilted. Therefore, according to the size of the discharge port 3, a pair of auxiliary plates 6 are set close to the surface of the anchor plate 1, limiting the position of the steel plate 5 and ensuring the flatness of the concrete structure surface after forming.

[0032] It can be understood that the present invention is described by some embodiments, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation mode. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, other modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrations shown and described here.
