Abstract
A portable flexural member deflection testing device comprises a scale plate and a top rod and a bottom rod fixed at the upper end and the lower end of the scale plate, wherein a communicating pipe is fixed to the scale plate, two ends of the communicating pipe are communicating pipe interfaces, the upper-end communicating pipe interface located on one side of the scale plate is a connecting water filling port, and the lower-end communicating pipe interface located on one side of the scale plate is continuously connected with a communicating pipe.A level pipe is horizontally embedded and fixed to the scale plate, the whole scale plate is covered with a glass cover plate, and two portable flexural member deflection testing devices are connected through the communicating pipe to form a communicator.The portable flexural member deflection testing device has the advantages that a communicator principle is adopted to combine the communicator with the scale plate, the heights of horizontal planes of measuring points and the bottom face of a flexural member are respectively measured, a deflection value of the flexural member is obtained by analyzing the height differences of the points, and the unevenness of the plate can be further analyzed.The portable flexural member deflection testing device remarkably reduces the costs of testing equipment, decreases the working amount of a field test, improves the working efficiency and is convenient to carry.
Description
Technical field
The present invention relates to existing building structure safety detection field.
Background technology
The amount of deflection detection of flexural member is one of important content of existing building structure safety detection.Flexural member refers to generally has moment of flexure and shearing combined effect and component that axle power is ignored on cross section, be generally the component such as beam, plate.And the amount of deflection detection of flexural member is to judge the major criterion that can the deformation of flexural member meet its instructions for use.Conventional amount of deflection detection method adopts bracing wire directly to measure, and the advantage of such method is that equipment is simple, it is possible to carry out multiple spot detection, directly obtain the amount of deflection numerical value of each measuring point, but measuring result error is relatively big, and the method needs to set up shelf, so requiring higher to detection site environment；Additionally adopt the method to carry out deflection metrology, no matter lay or snap the line, all more complicated consuming time.
Summary of the invention
The deficiency that the present invention exists based on above deflection metrology method, it is proposed to a kind of portable flexural member deflection test device.
A kind of portable flexural member deflection test device, present invention is characterized in that and include one piece of graduated tile and be fixed on the push rod at the upper and lower two ends of graduated tile, bottom bar, graduated tile is fixed with communicating pipe, communicating pipe, two ends were communicating pipe interface, being positioned at graduated tile side to be set to connect water filling port in communicating pipe interface upper end, lower end is positioned at that graduated tile side is continuous connects pipe；On graduated tile, horizontal build-in has levelling tube, and is coated with glass cover-plate on whole graduated tile；Adopt two set apparatus of the present invention to utilize communicating pipe to be connected and namely form linker.
Water filling port of the present invention is connected with adopting transparent resin pipe between communicating pipe interface, and described water filling port adopts funnel-shaped structure, and material adopts polyethylene.
Communicating pipe of the present invention, interface was set to threaded copper pipe interface.
Having hole groove in the middle of the scale of graduated tile of the present invention, graduated tile adopts aluminium alloy plate.
Push rod of the present invention should keep isometric by other push rod matched.
The invention has the beneficial effects as follows: adopt law of connected vessels (namely direct and atmosphere liquid level is always to maintain sustained height), linker is combined with graduated tile, measure the horizontal plane of each measuring point and the height of flexural member bottom surface respectively, draw the deflection value of flexural member by analyzing the discrepancy in elevation of each point, its irregularity degree can be analyzed further for plate.The method significantly reduces test equipment cost, reduces the workload of on-the-spot test, improves work efficiency and easy to carry.

1, by communicating pipe 6 device equal for two push rod 3 length connected and namely define " U-tube " (linker)；
2, device setting is positioned over ground；
3, injecting colored liquid from side water filling port, water injection rate is in the scope of the equal readable of both sides graduated tile；
4, the air in communicating pipe is discharged to reduce measurement error；
5, push rod is placed in bottom each measuring point by lift arrangement respectively；
6, adjusting apparatus keeps level tube bubble placed in the middle；
7, from graduated tile reading numerical values record respectively.
