Description
Technical field
The utility model is related to a kind of freely-supported distribution beam, more particularly to a kind of adjustable positioning freely-supported distribution beam.
Background technology
At present, the fast development with China's building industry in recent years, each institution of higher learning opened up one after another structure, bridge tunnel,
The relevant specialities such as ground, related personnel need to carry out a large amount of freely-supported load test during academic program, and experiment every time all needs
Matched freely-supported distributor is wanted, is not quite similar due to testing every time, freely-supported distributor used cannot obtain repeating profit
With not meeting us and build a resource-conserving society purpose；Simultaneously because distribution beam insufficient rigidity, supporting stand size are not inconsistent, loading
Point positional precision is inadequate, it is impossible to which different degrees of error can be carried out to test tape by fully meeting many reasons such as freely-supported condition, unfavorable
In the development of our Test And Research Works.
Invention content
The purpose of this utility model cannot be repeated to solve the freely-supported distributor during correlation engineering is tested
The problem of utilization and provide one kind it is adjustable positioning freely-supported distribution beam.
Adjustable positioning freely-supported distribution beam provided by the utility model includes type beam and fixture, and fixture is threaded through type beam
Lower part, the lower section setting backing plate of fixture, bearing is provided between the bottom of fixture and backing plate top surface.
Type beam is i-shaped beams, and the outside of belly of type beam is provided with location graduation.
Fixture is equipped with several, and fixture is bolted on the lower part of type beam, and the top surface of fixture is equipped with spirit lever, folder
The side of tool is equipped with position line, and position line is also equipped on backing plate side corresponding with the position line, and the bottom surface of fixture is arc,
The top surface of backing plate is also arc, and the curvature of fixture bottom surface and backing plate top surface is corresponding to the curvature of bearing.
The producing principle of the utility model：
The corresponding location graduation on type beam of fixture is determined according to test specimen loading requirement, by fixture from two end cap of type beam
Enter, the position line on fixture is aligned with the location graduation on identified type beam, bolt is tightened, by the corresponding position on type beam
Graduation mark centering test specimen in the middle part of, by the position line in the position line and fixture on backing plate to just, passing through the bubble of fixture top surface
Spirit level checks whether test specimen horizontal, and freely-supported distribution boom device installs if horizontal, otherwise adjust test specimen bearing until
Spirit lever is horizontal.
The beneficial effects of the utility model：
Adjustable positioning freely-supported distribution beam simple structure provided by the utility model, can meet the loading of different loads
Distribution requirements can meet the loading distribution requirements of most varying cross-section size test specimen.Device by the common steel in market into
The simple processing of row is composed, and is made simply, at low cost.Device at the trial pacify by fast and easy positioning load(ing) point, fast and easy
Dress and dismounting.Principle of device is clear, and stress is clear and definite, and testing crew can be made further to obtain more accurate data information.

Specific embodiment
Shown in please referring to Fig.1 to Fig.3：
Adjustable positioning freely-supported distribution beam provided by the utility model includes type beam 1 and fixture 2, and fixture 2 is threaded through type
The lower part of beam 1, the lower section of fixture 2 set backing plate 3, bearing 4 are provided between 3 top surface of bottom and backing plate of fixture 2.
Type beam 1 is i-shaped beams, and the outside of belly of type beam 1 is provided with location graduation 5.
There are two fixture 2 is set, fixture 2 is fixed on the lower part of type beam 1 by bolt 6, and the top surface of fixture 2 is equipped with spirit level
Device 7, the side of fixture 2 are equipped with position line 8, position line 8, fixture 2 are also equipped with on 8 corresponding 3 side of backing plate of position line
Bottom surface for arc, the top surface of backing plate 3 is also arc, and the curvature of 3 top surface of 2 bottom surface of fixture and backing plate is corresponding to the curvature of bearing.
The producing principle of the utility model：
The corresponding location graduation 5 on type beam 1 of fixture 2 is determined according to test specimen loading requirement, by fixture 2 from type beam 1
Both ends are inserted in, and the position line 8 on fixture 2 is aligned with the location graduation 5 on identified type beam 1, bolt 6 is tightened, by type beam 1
On corresponding position graduation mark centering test specimen in the middle part of, by the position line 8 on the position line 8 on backing plate 3 and fixture 2 to just, leading to
The spirit lever 7 for crossing 2 top surface of fixture checks whether test specimen is horizontal, and freely-supported distribution boom device installs if horizontal, no
Test specimen bearing is then adjusted until spirit lever 7 is horizontal.
