Description
Technical Field
The utility model belongs to the technical field of the structural test, specifically be the screw of leveling test component (hereinafter "test piece") among the structural test.
Background
In structural tests, a test piece is often leveled by using a bulk material such as sand, a flexible material such as a rubber pad, and a jack.
These measures are simple and easy to implement, and have the advantages that:
firstly, the deformation of the bulk material, the flexible material and the jack is increased along with the increase of the test loading capacity, so that the test piece cannot be leveled actually, and the accuracy of test data acquisition is seriously influenced; secondly, the jack has a large height-width ratio, is easy to lose and stably topple, and can cause equipment damage and casualty; thirdly, the load bearing capacity of the bulk material and the flexible material is small, so that large test load capacity cannot be met, the load bearing capacity of the jack is determined by the type of the jack although the jack has certain load bearing capacity, and the load bearing capacity beyond the rated load bearing capacity range of the types cannot be loaded due to the limited number of the types of the jack.
Disclosure of Invention
The utility model aims to remedy the defect of the used facility of leveling test piece in the structural test, improve the accuracy of test data acquisition, guarantee the safety of testing personnel and equipment conscientiously.
The technical problem to be solved by the utility model is to provide a leveling device that height-adjustable, stable, bearing capacity is big to prior art method not enough.
In order to solve the technical problem, the utility model discloses a screw, this screw comprises taking base bolt, height-adjustable nut and height-adjustable backing plate, takes the base bolt to comprise round bar and base, takes the base bolt to put on experimental pedestal, and height-adjustable backing plate penetrates the round bar of this bolt, arranges the base upper portion of this bolt in, and height-adjustable nut penetrates the round bar of taking the base bolt, arranges the upper portion of height-adjustable backing plate in.
Preferably, the bolt with the base consists of a round rod and a base.
Preferably, the round bar is threaded over the entire height thereof, the thread inner diameter is 100mm to 2000mm, and the ratio of the thread inner diameter to the height of the round bar is 0.8.
Preferably, the cross section of the base is circular, and the ratio of the diameter of the circle to the inner diameter of the thread of the round rod is 1.8.
Preferably, the thickness of the base is 30 mm-50 mm.
The four technical schemes can effectively improve the anti-instability capability and the bearing capacity of the leveling screw.
Preferably, the ratio of the height-adjustable nut to the height of the round rod is 0.5-0.8.
Preferably, the height-adjustable nut has a circular cross-section, and the ratio of the diameter of the circle to the diameter of the base is 0.7.
The two technical schemes can lead the leveling screw to have small load deformation, large range of adjustable height, strong instability resistance and large bearing capacity.
Preferably, the cross section of the height-adjustable base plate is circular, and the ratio of the diameter of the circular to the diameter of the height-adjustable nut is 1.2.
Preferably, the ratio of the height-adjustable pad to the height of the round bar is 0.2.
Through the two technical schemes, the height-adjustable base plate has strong locking capacity, so that the loaded deformation of the height-adjustable nut is reduced, and the instability resistance and the bearing capacity of the leveling screw are improved.
The beneficial effects of the utility model are that, can the holding surface of leveling the test piece, support the test piece steadily safely, guarantee experimental data's accurate collection avoids the emergence of incident.
