Description

Technical Field

[0001] This application relates to the technical field of bridge construction, and particularly to a tool for measuring the position of a prestressed anchor plate of a bridge. Background Art

[0002] In the design and construction of bridges, prestressed tendons are key components for the force-bearing of bridge structures. The accuracy of their alignment is very important for the safety and stability of the overall structure, and the position of the anchor plate is one of the key points for controlling the alignment of prestressed tendons.

[0003] The anchor plate is usually arranged in the tensioning groove of the beam segment, and usually the tensioning groove adopts an inward-inclined design, which makes it very difficult to directly use tools such as a ruler to measure the height of the anchor plate and is prone to measurement errors. In addition, a circular hole is provided in the middle part of the anchor plate. When measuring and positioning, there are often large measurement errors in the center position of the positioning circular hole.

[0004] The measurement error of the position of the anchor plate will affect the tensioning effect of the prestressed tendon and the overall force-bearing state of the bridge, thus affecting the force-bearing performance of the bridge and making it impossible to effectively guarantee the safety of the bridge.

[0034] The anchor backing plate is usually arranged in the tensioning groove of the beam segment, and the tensioning groove usually adopts an inward inclination design, which makes it very difficult to directly use tools such as a straight ruler to measure the height of the anchor backing plate and is prone to measurement errors. In addition, a circular hole is provided in the middle part of the anchor backing plate. When measuring and positioning, there are often large measurement errors in the center position of the positioning circular hole.

[0035] The measurement error of the position of the anchor backing plate will affect the tensioning effect of the prestressed tendon and the overall stress state of the bridge, thus affecting the stress performance of the bridge and making it impossible to effectively guarantee the safety of the bridge.

[0036] In view of the above problems, the embodiment of the present application provides a tool for measuring the position of the bridge prestressed anchor backing plate, which can conveniently measure the height of the anchor backing plate and ensure the safety of the bridge.

[0045] See Figures 1-7 , a tool for measuring the position of the bridge prestressed anchor backing plate, comprising:

[0046] A rod ruler 1, on which height scale values are set, and a base 2 is installed at the bottom of the rod ruler 1.

[0047] A cone 4, a clamping groove 401 is provided at the bottom of the cone 4, and a first threaded hole 402 is provided on the side wall of the cone 4 corresponding to the position of the clamping groove 401.

[0048] The spirit level 3 is fixedly installed in the card slot 401 by bolts passing through the first threaded hole 402, and the top of the spirit level 3 is flush with the center of the cone 4.

[0049] In this embodiment, by installing the cone 4 on the spirit level 3, the spirit level 3 with the cone 4 can accurately locate the center of the circular hole of the anchor plate, make the upper edge of the spirit level 3 flush with the center of the anchor plate, and the vertical height value of the center of the anchor plate can be intuitively read after adjusting the spirit level 3 to be horizontal.

[0050] Specifically: a positioning block 301 is arranged at the front end of the spirit level 3; a positioning slot hole 403 for correspondingly installing the positioning block 301 is arranged in the card slot 401.

[0051] In this embodiment, by arranging the positioning block 301 at the front end of the spirit level 3, the positioning block 301 can be embedded into the positioning slot hole 403 of the cone 4, enabling the spirit level 3 and the cone 4 to be closely fitted and improving the installation stability.

[0052] Specifically: a second threaded hole 101 is arranged at the bottom of the rod ruler 1, a threaded rod 201 is arranged at the bottom of the rod ruler 1, and the rod ruler 1 is fixedly installed on the base 2 by means of threaded connection.

[0053] In this embodiment, the rod ruler 1 is fixed on the base 2 by means of threaded connection, which is convenient for disassembly and assembly, can ensure the accuracy, is convenient for transportation, and can ensure the stability of the tool during use.

[0054] Specifically: a rubber anti-slip pad is installed at the bottom of the base 2.

[0055] In this embodiment, by arranging the rubber anti-slip pad, the base 2 can be effectively prevented from sliding during measurement, ensuring the stability of measurement.

[0056] The usage method of the tool for measuring the position of the bridge prestressed anchor plate in this application is as follows:

[0057] During use, the rod ruler 1 is erected on the bottom formwork of the pedestal at the beam end of the anchor plate to be measured. The operator holds the spirit level 3, inserts the triangular cone at the end of the spirit level 3 into the circular hole of the anchor plate, adjusts the spirit level 3 to be horizontal through the position of the bubble, and reads the reading of the rod ruler 1 corresponding to the upper edge of the spirit level 3 when the spirit level 3 is horizontal, which is the height of the center of the anchor plate.

[0058] The technical solution of the embodiment of this application has the following beneficial effects:

[0059] In this application, by installing the cone 4 on the spirit level 3, the spirit level 3 with the cone 4 can accurately locate the center of the circular hole of the anchor backing plate, making the upper edge of the spirit level 3 flush with the center of the anchor backing plate. After adjusting the spirit level 3 to be horizontal, the vertical height value of the center of the anchor backing plate can be visually read out to ensure the safety of the bridge.

[0060] This application is convenient to operate, easy to disassemble and assemble, can ensure accuracy, and is convenient for transportation. The measurement work can be completed independently through one operation.
