Type fixed-hinged support correlation computations process
1st, U-shaped fixed-hinged support bearing capacity N is calculated
As shown in figure 1, according to U-shaped fixed-hinged support design feature, its bearing capacity is based on bearing plate with base contacts area
Calculate：
If round bar radius R=200mm
U-shaped bearing plate and base contacts face length B=2 × R+120mm=520mm
Bearing plate takes arc of contact chord length L=52mm with base contacts face width
Q390 steel comprcssive strength design loads f=295N/mm2
Bearing capacity N=B × L × f=7976.8kN
It is 7976.8kN to calculate for the U-shaped fixed-hinged support bearing capacity that round bar radius is R=200mm by above-mentioned formula.
2nd, rod member fastening 1 checking of bearing capacity of high-strength bolt
As shown in figure 4, rod member fastening high-strength bolt 1 is 8.8 grades of M24 bolts, long 182mm, end are that radius is justified for 12mm
Arc, is mainly used in fixing circular rod member during test, and its maximum load capacity F is calculated as bolt effective area Ae=35.25mm2It is strong with which
Degree design load ft b=400N/mm2Product.
F=Ae×ft b=14.1kN
Therefore the bearing capacity of single rod member fastening high-strength bolt 1 is 14.1kN.
3rd, 4 checking of bearing capacity of baffle plate, as shown in figure 8,
Baffle plate 4 mainly prevents U-shaped bearing plate and the mutual changing of the relative positions of base plate in process of the test, and undertakes the power.The carrying of baffle plate
Power fastens high-strength bolt 3 by four baffle plates and undertakes, i.e., baffle plate bearing capacity is the bearing capacity that 4 times of baffle plates fasten high-strength bolt 3；Baffle plate
4 high 80mm, long 180mm, thick 20mm, open 12mm circular holes above, fasten high-strength bolt 3 for threading；
As shown in figure 3, baffle plate fastening high-strength bolt 3 is 8.8 grades of M12 bolts, baffle plate fastens the diameter of high-strength bolt 3
12mm, long 50mm, for fixed dam 4 in U-shaped bearing plate 2.
Effective area Ae=8.4mm2With its strength failure criterion ft b=400N/mm2Product
F=4×Ae×ft b=13.3kN
Therefore the bearing capacity of baffle plate 4 is 13.3kN.
By above-mentioned computational methods, U-shaped fixed-hinged support bearing capacity, fixing force and baffle plate bearing capacity can be checked.
This utility model designs and produces out U-shaped fixed-hinged support by 5 building blocks, for the special of round bar rod member
Property design fixed-hinged support, meet beam test requirement, and simple, economical, conveniently, safely using journey, substantially increase test
Efficiency, and ensure that the personnel safety in process of the test, substantially increase comprehensive benefit.
Above case study on implementation is merely to illustrate preferred implementation of the present utility model, but this utility model is not limited to
State embodiment, in the ken that the field those of ordinary skill possesses, it is of the present utility model spirit and principle it
