Problems solved by technology

[0004] In the existing tests, most of the fire tests are carried out with scaled-down building structures and components. Due to the size effect and film effect, the performance indicators of the obtained building structures and components under fire are different from those produced under actual fire conditions. There is a large difference in performance indicators

Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0039] combine Figure 1-Figure 9 , This embodiment includes four parts: a furnace body 25, a support column, a counter force loading device, and a data acquisition system. The furnace body includes outer furnace wall 1, inner furnace wall 2, oil supply pipeline 3, water circulation pipeline 4, flue exhaust duct 5, thermocouple 6, ignition nozzle 7, automatic ignition computer control system, line pipeline 8, etc., among which thermoelectric Even 6 is used to test the temperature in the furnace. The support column mainly includes the support column 9 of the well-shaped foundation and the bolt 10 pre-embedded on the foundation. The support column is generally cast-in-place with the slab, and the support column can be reused when the slab of the same size is used for a comparative test. The counter force loading device includes a counter force frame ...

Abstract

The invention provides a testing device for testing the fire resistance of a column support full-scale reinforced concrete two-way slab and an implementation method thereof. The testing device mainly comprises a furnace body, a support column, a counterforce loading device and a data acquisition system, wherein the furnace body is arranged under a reinforced concrete two-way slab; the counterforce loading device is arranged above the reinforced concrete two-way slab; the reinforced concrete two-way slab is arranged on the support column; and the data acquisition system is arranged on the reinforced concrete two-way slab and the furnace body. The testing device can carry out better fire test of the column support full-scale reinforced concrete two-way slab to simulate actual fire to carry out fire-tolerant test, test the fireproof limit of the column support full-scale reinforced concrete two-way slab and carry out research on the working mechanism of the slab in fire; therefore, the testing device provides a basis for structural design based on fire safety.

Description

(1) Technical field [0001] The invention relates to the technical field of disaster prevention and mitigation of building structures, in particular to a fire resistance test device for column-supported full-scale reinforced concrete two-way slabs that can be used in various engineering situations. (2) Background technology [0002] In recent years, the number and losses of building fires in my country have remained high, and there have been many large and major fires. The causes and conditions of the fires are complicated and difficult to fight fires. Under the existing conditions, it is an important topic in the field of building fire research to study the fire resistance of existing structures and how to improve the fire resistance of building structures and components through rational design. [0003] In recent years, the beamless floor structure has been widely used in multi-storey and high-rise buildings with large spans, large loads, and large spaces, such as commercia...
