Abstract

The utility model discloses a simply supported beam span measuring device of circulated use, it is equipped with the cross central line on the front panel of span model, is equipped with the prism in central point department, respectively is equipped with a leveling bubble at the both ends of horizontal line, and the interval is equipped with four pre-buried bolt draw-in grooves of the support plate of opening that makes progress on the span model. The structure of the utility model is processed in advance, and is directly fixed on the support plate of the beam body when in use, and the utility model only needs to be integrally detached from the support plate of the beam body and then fixed on the support plate of the subsequent beam body when the subsequent beam body is inspected after the measurement and inspection are finished, thereby effectively improving the measurement efficiency; and the device can be recycled, so that the material and labor cost are saved, and the working efficiency is improved. The utility model discloses simple structure, the preparation is convenient, and overall stability is good, and the prism through on the roof beam body both ends span model is measured and is reachd the coordinate and ask length, can accurate measurement roof beam body span.

Description

Recyclable simply supported beam span measuring device

Technical Field

The utility model belongs to the technical field of bridge engineering building construction measurement technique and specifically relates to a simply supported beam span measuring device of circulated use is related to.

Background

The historical development of the railways in the world proves that the high-speed railways are the inevitable trend of the development of the economic society. In the high-speed development of the present day, high-speed railways are more and more. Due to the complex terrain in China and numerous large rivers, mountains and canyons, various railway bridges need to be built to cross rivers and canyons and cross Chong mountain and steep mountains. However, in the construction process, the span of the bridge body needs to be inspected to determine whether the railway bridge is qualified, and particularly, the span inspection of the bridge body is particularly important for simply-supported bridges of various long-distance lines. The beam body is measured by a steel tape for span inspection, and the method has the following defects: 1. various errors: the length error of the ruler, the error of temperature change, the error of tension change, the error of the steel ruler not being horizontal during leveling, the error of the alignment not being straight, the steel ruler sag error, the error of the measurement itself. 2. Time and labor costs are wasted.

Disclosure of Invention

An object of the utility model is to provide a but recycle, avoid the material extravagant, save the cost of labor, improve the simply supported beam span measuring device of operating efficiency and measurement accuracy.

The purpose of the utility model is realized like this:

a simply supported beam span measuring device capable of being recycled is characterized in that: the device comprises a T-shaped span sample plate, wherein a cross center line is arranged on a front panel of the span sample plate, a prism is arranged at the center point, two leveling bubbles are respectively arranged at two ends of a transverse line, and four upwards-opened support plate pre-embedded bolt clamping grooves are arranged on the span sample plate at intervals.

The two support plate embedded bolt clamping grooves on the left side and the two support plate embedded bolt clamping grooves on the right side are vertically and symmetrically arranged.

Compared with the prior art, the utility model has the advantages of:

the structure of the utility model is processed in advance, when in use, the structure is directly fixed on the support plate of the beam body, and when in subsequent beam body inspection after the measurement inspection is finished, the utility model only needs to be integrally detached from the support plate of the beam body and then fixed on the support plate of the subsequent beam body, thereby effectively improving the measurement efficiency; and the device can be recycled, so that the material and labor cost are saved, and the working efficiency is improved. The utility model discloses simple structure, the preparation is convenient, and overall stability is good, measures through the prism on the span model and reachs the coordinate and ask length, can accurate measurement roof beam body span.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a simply supported beam span measuring device of circulated use, includes the span model 4 of "T" shape, is equipped with cross central line 5 on the courage panel of span model 4, is equipped with prism 1 in central point department, respectively is equipped with a leveling bubble 3 at the both ends of horizontal line, and the interval is equipped with four upward open-ended bedplate embedded bolt draw-in grooves 2 on span model 4.

Two bearing plate embedded bolt draw-in grooves 2 on the left and two bearing plate embedded bolt draw-in grooves 2 on the right are vertical symmetrical arrangement.

The using method comprises the following steps:

as shown in fig. 3, firstly, dust and sundries remaining in bolt holes 7 on a beam bottom support plate 6 are cleaned, then a support plate pre-embedded bolt clamping groove 2 of a span sample plate 4 is aligned with the bolt holes 7 at the bottom of the beam bottom support plate 6 to enable the two to be coincident, bolts 8 are aligned with the bolt holes 7 to be screwed, leveling bubbles 3 of the simply supported beam span measuring device are adjusted and controlled, the span sample plate 4 is moved to the other end of a beam body, the total station is erected to the middle of the outer span of the beam body to aim at positive and negative mirrors of prisms 1 at two ends to alternately measure four groups of data, and the distance between two points is calculated through mileage offset, so that the span of the beam body can be accurately measured.
