Description
Technical field
The invention belongs to field of civil engineering, are related to a kind of loading system, and in particular to a kind of full-scale vertical member is high
Warm loading system.
Background technique
In general, under high temperature of fire effect, the mechanical property of structural material has a degree of decaying, causes to tie
The bearing capacity decline of structure and component at high temperature finally causes structure to generate certain damage or even collapse.In September, 2001
11, World Trade Organization, U.S. mansion collapsed under high temperature of fire because serious fire, main structure occur after the collision by aircraft,
About 2998 people death is ultimately caused, similar serious building fire case occurs repeatedly.Therefore the high temperature load test pair of test specimen
It is of great significance in structure design.
In current experiment research, it is limited to test apparatus, most of tests take first heating to reload until test specimen destroys
Test model, i.e., be first warming up to design temperature using stove, further take out test specimen and be placed in press machine and test its ultimate bearing capacity.
The advantages of this test model is that instrument is used separately, easy to operate.It is inevitable while test specimen heats up but in reality
Bearing load, therefore current test mode cannot simulate test specimen mechanical property under real high-temperature condition very well.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of existing instrument, a kind of full-scale vertical member high temperature provided is loaded
System, loading system applicability with higher and operability while allowing test specimen to meet high temperature by fire, load maximum value
For 1000 tons of pressure, matching for high temperature furnace and loading device is realized.The test platform meets fast industrialization simultaneously
Demand, can be in factory's preprocessing, and directly lifting splicing, has a foreshadowing at the construction field (site) for the popularization of high temperature load test.
The technical solution adopted by the present invention are as follows: a kind of full-scale vertical member high temperature loading system, including reaction frame, conversion
Crossbeam, triangle steel frame columns, angle brace, sliding beam, concave-board and block of wood；
The reaction frame is bolted with conversion crossbeam；
The conversion crossbeam is bolted with triangle steel frame columns, and both sides set up and install thousand between angle brace, with sliding beam
Jin top is used as loading device；
The one face welded reinforcement of triangle steel frame columns passes through pulley as guide track system, the sliding beam and triangle steel frame columns
Connection composition pulley system；
The concave-board includes upper recess plate and lower end concave-board, and the upper recess plate and sliding beam are connected by bolt
It connects, the lower end concave-board is bolted with block of wood, and the vertical member tested passes through upper recess plate and lower end groove
Plate is fixed.
Preferably, the column of the reaction frame is H profile steel or box column, the beam of reaction frame is lattice girder or box beam, column
It is bolted between beam.
Preferably, the crossbeam of converting is box beam, the triangle steel frame columns are box column.
Preferably, described block of wood is quadrate steel pipe column, block of wood is one or more, facilitates and adjusts vertical member by fiery position
It sets, between block of wood, block of wood and ground is bolted.
Preferably, the upper recess plate and lower end concave-board are hingedly to contact with the connection of vertical member.
Sliding beam is by the support of two column sides steel plate outstanding when the present invention is not loaded with, and when load can stretching with jack
It contracts and changes position.The present invention is mainly bolted, and guarantees meet the needs of fast industrialization in the case where bearing capacity.Steel
Beam, steel column section and bolt quantity are determined according to Force Calculation.Vertical member is installed between lower notches plate after being put into stove,
Stove is turned off to be tested.While the present invention allows test specimen to meet high temperature by fire, the pressure that load maximum value is 1000 tons is real
Existing high temperature furnace and loading device match.
The utility model has the advantages that the present invention allows test specimen to meet high temperature by the same of fire by full-scale vertical member high temperature loading system
When, load maximum value is 1000 tons of pressure, and loading position is not limited to the position of reaction frame, height, realize high temperature furnace with
Loading device matches.
