Description

T-beam dimension measuring tool

technical field

The utility model relates to a tool for measuring the external dimension of a T beam.

Background technique

T-beam is a kind of railway bridge. In order to ensure the quality of T-beam dimensions, before installing and using T-beam, the lower flange width and web thickness of T-beam must be measured to check whether it is qualified. The current measurement method is to use a tape measure to manually measure the distance between the lower flange and the two sides of the web. Since the tape measure has no positioning function, it can only roughly measure the width of the lower flange of the T-beam and the thickness of the web. The measurement error is relatively large. The value obtained is not accurate, and there is no guarantee that the detected T-beam meets the requirements of the national certification and license inspection beam dimensions.

Contents of the invention

The utility model aims to solve the above-mentioned technical problems, and provides a method for measuring the lower flange width and web thickness of the T-beam, which can greatly reduce the measurement error, improve the measurement accuracy, and ensure the detected T-beam. It is a T-beam external dimension measurement tool that meets the requirements of national certification and license inspection for beam external dimensions.

The technical solution of the utility model is:

A tool for measuring the external dimensions of a T-beam, which is special in that it includes two oppositely arranged rests, and the rests are composed of a horizontal seat post, a vertical rod vertically arranged at the inner end of the seat post, and connected to the seat post. The diagonal rod between the rod and the vertical rod is formed; the main measuring scale is placed horizontally at the inner end of one of the rods, and the axial sliding hole is set on the other seat rod, and the main measuring rod passes through the sliding hole; the upper part of the two vertical rods is set The sliding sleeves are arranged oppositely, and the auxiliary measuring scales sliding laterally are respectively arranged in the two sliding sleeves.

Further, there are two sets of auxiliary measuring scales, which are arranged up and down on the pole for multi-point measurement to improve measurement accuracy.

Further, reinforcing plates are respectively arranged at the adjacent connections of the seat post, the vertical bar and the diagonal stay bar, so as to enhance the structural stability of the frame.

The beneficial effects of the utility model are:

Since the main gauge is placed horizontally on the inner end of the seatpost of one of the rests, and an axial slide hole is set on the seatpost of the other rest, the main gauge passes through the slide holes; the lower flange at the bottom of the T-beam is measured When the width is wide, vertically clamp the vertical poles on the two support frames against the two sides of the lower flange of the bottom of the T-beam, which not only ensures the parallelism between the main measuring scale and the lower flange of the T-beam, but also ensures that the two vertical poles The perpendicularity to the lower flange of the T-beam ensures that the distance between the two uprights is the width of the lower flange of the T-beam; since the auxiliary measuring scales for lateral sliding are respectively set in the sliding sleeves on the upper parts of the two uprights, the measurement of the T-beam When the web width is 100%, place the two auxiliary measuring scales on both sides of the web of the T-beam respectively, and calculate the difference between the readings of the two auxiliary measuring scales and the reading of the main measuring scale, which is the web width, and the structure is simple , easy to operate, greatly reducing the measurement error, improving the accuracy of measurement, and ensuring that the detected T-beam meets the requirements of the national certification and license inspection beam dimensions.

detailed description

As shown in the figure, a T-beam external dimension measuring tool includes two oppositely arranged support frames 1, and the support frame 1 is composed of a horizontal seat post 101 and a vertical post vertically installed at the inner end of the seat post 101. 102. The diagonal stay rod 103 connected between the seat post 101 and the vertical rod 102 is composed of a reinforcement plate 2 respectively installed at the adjacent connections of the seat post 101, the vertical rod 102 and the diagonal stay rod 103 to enhance the structural stability of the support frame 1; The inner end of one rod 101 is horizontally installed with the main measuring stick 3, and the axial sliding hole 4 is arranged on the other seat rod 101, and the main measuring stick 3 passes through the sliding hole 4; Arranged sliding sleeves 5, and in each sliding sleeve 5, a secondary measuring stick 6 that slides laterally is respectively inserted.

During the measurement operation, first at one end of the T-beam, vertically clamp the vertical rods 102 on the two brackets 1 against the two sides of the lower flange at the bottom of the T-beam, and record the measurement reading of the main measuring stick 3, which is the lower flange of the T-beam. The width of the flange; then place the four sub-scales 6 on both sides of the web on the upper part of the T-beam respectively, and record the measurement readings of the four sub-scales 6, and then calculate the sum of the readings of the upper and lower sets of sub-scales 6 The average value, and calculate the difference between the main measuring stick 3 and the average value, which is the width of the T-beam web. The operation is convenient and fast, the error is reduced, and the measurement is accurate.
