The utility model relates to a measuring device for structural deflection increment, which is provided with a suspension rod connected with a measuring point of the structure, wherein the lower end ofthe suspension rod is connected with a heavy hammer which is arranged in a vertical sleeve; the sleeve is provided with an adjustable supporting leg; and a vertical displacement measuring device of the heavy hammer is arranged below the sleeve. A thermometer placing groove is arranged on the side wall of the sleeve. The suspension rod is formed by a plurality of mutually-sleeved sections and locking mechanisms are arranged among the sections. The utility model has convenient assembly, disassembly, transportation and storage, simple and convenient operation and high measuring precision, is suitable for concrete structure or member static load tests, steel structure static load tests, space grid structure static load tests, bridge structure static load tests and the like.
Description
Technical field
The utility model relates to a kind of building structure static load test and measures the testing equipment that its amount of deflection changes, particularly a kind of structural deflection increment measurement device down.
Background technology
Existing amount of deflection incremental detection method adopts and hangs steel ruler or steel tape, and the principle of utilizing hanging object and malformation to coordinate is advanced the side measurement, but there is shortcoming in this method: 1, hanging steel ruler or steel tape, to be subjected to the influence of wind-force bigger, and measuring error is bigger; 2, hang steel ruler or steel tape when longer, under the bigger environment of temperature variation, temperature is bigger to the measurement result influence; 3, adopt the spirit-leveling instrument reading, precision is higher in the short period of time, but measuring period when longer, measurement environment can produce bigger influence to spirit-leveling instrument, influence measuring accuracy; 4, when load mode measurement structure amount of deflection increment was hung in employing, the spirit-leveling instrument visual line of sight can be restricted, and was not easy to operation; 5, need to adopt artificial reading, certainly exist the reading error of human factor.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of simple to operation, structural deflection increment measurement device that measuring accuracy is high.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of structural deflection increment measurement device, be characterized in: be provided with a suspension rod that is connected with the measurement point of structure, the lower end of suspension rod is connected with a weight, weight is arranged in the vertical sleeve, sleeve is provided with adjustable supporting leg, is provided with weight vertical displacement measurement mechanism below sleeve.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, be provided with the thermometer standing groove on the sidewall of sleeve.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, along the outer wall of sleeve three adjustable supporting legs is set evenly, and the lower end of supporting leg is contained on the fixed mount.
The technical problems to be solved in the utility model can also come to realize that further described suspension rod is made of some joints of mutual socket by the following technical programs, is provided with latch mechanism between joint and the joint.
The utility model advantage compared with prior art is: 1, adopt suspension rod to replace steel ruler or steel tape, rigidity own is bigger, is not subjected to windage substantially, can improve measuring accuracy; 2, suspension rod adopts the socket connected mode, and length is unrestricted, and convenient installation, dismounting are transported and deposited; 3, three leg lengths can be regulated, and test is not subjected to the requirement of levelling of the land degree, and the ground fixed mount can be connected with ground by expansion bolt with ground, guarantee the invariant position of test point; 4, device design itself has the open type tube seat of laying temperature meter, so that the record temperature variation when late time data is handled, can be eliminated the influence of temperature to measurement result; 5, measuring point is subjected to the protection of tripod, also can use and hang to load and test the amount of deflection variation.This device is applicable to: xoncrete structure or the test of member static load, the test of steel construction static load, the test of space grid structure static load, the test of bridge structure static load etc.
