Description

Simple device for monitoring displacement of expansion joint beam end

Technical Field

The utility model relates to a monitoring displacement technical field, in particular to simple and easy device of monitoring expansion joint beam-ends displacement.

Background

The width of the beam end seam at the expansion joint is an important parameter of a bridge structure, and the prior art can measure the width of the beam end seam directly through a steel tape or measure the width of the beam end seam in a manner of erecting a dial indicator, an extensometer and the like. The positions of the steel tape in the multiple measuring processes are not uniform, and the consistency between the front and the back is poor; the dial indicator or extensometer has high precision, the base point changes due to bridge vibration, data may be abnormal, and the cost is relatively high.

SUMMERY OF THE UTILITY MODEL

Not enough to the above among the prior art, the utility model provides a simple and easy device of monitoring expansion joint beam-ends displacement, its is rational in infrastructure, and the cost is lower, can acquire two sets of important data simultaneously, and beam-ends seam is wide promptly, beam-ends and pier longitudinal displacement relation.

In order to achieve the purpose of the utility model, the utility model adopts the technical scheme that: the simple device for monitoring the displacement of the beam end of the expansion joint comprises a bridge pier, wherein two sides above the bridge pier are fixedly connected with supports, the upper ends of the two supports are fixedly connected with beam bodies, a seam is arranged between the two beam bodies, the beam bodies on two sides of the seam are respectively and fixedly connected with a first pointer and a second pointer, and the bridge pier is fixedly connected with a reference ruler.

As an improvement: the first pointer and the second pointer are both proper in length and are arranged downwards.

As an improvement: the reference ruler is of a double-sided structure.

Compared with the prior art, the utility model the advantage lies in: selecting pointers with reasonable length to bond the ends of the two side beams, converting the relative seam width of the beam ends into the relative distance between the pointers, vertically bonding the double-sided scale reference ruler on a bridge pier, reading the positions indicated by the two pointers, subtracting the numerical values of the two pointers to obtain the current seam width data of the beam ends, and obtaining the seam width change condition of the beam ends through multiple data readings. And reading the same pointer indication position for multiple times, and obtaining the longitudinal displacement relation between the beam end and the pier through data analysis at this time and last time. And this device is when using, and is with low costs, convenient operation, to a certain extent, increases the use convenience.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the simple device for monitoring the displacement of the beam end of the expansion joint comprises a bridge pier 1, wherein two sides above the bridge pier 1 are fixedly connected with supports 2, the upper ends of the two supports 2 are fixedly connected with beam bodies 3, a gap is formed between the two beam bodies 3, the beam bodies 3 on two sides of the gap are respectively and fixedly connected with a pointer I4 and a pointer II 5, the pointer I4 and the pointer II 5 are both proper in length and are arranged downwards, a reference ruler 6 is fixedly connected to the bridge pier 1, and the reference ruler 6 is of a double-faced structure.

When the utility model is implemented, two pointers with reasonable length are selected as the first pointer 4 and the second pointer 5, the two pointers are bonded with the ends of the beam bodies 3 at two sides, and the relative seam width of the beam ends is converted into the relative distance between the first pointer 4 and the second pointer 5; and vertically sticking the double-sided scale reference ruler 6 to the pier 1. Reading the positions currently indicated by the first pointer 4 and the second pointer 5, and subtracting the numerical values of the two pointers to obtain the current beam end seam width data; the change condition of the seam width of the beam end can be obtained through multiple data readings. And reading the same pointer indication position for multiple times, and analyzing data at this time and the last time to obtain the longitudinal displacement relation between the beam end and the pier 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
