Embodiment 1

[0024] Embodiment one: if Figure 1-Figure 4 As shown, in this embodiment, the shear wall fire test device under the vertical load includes a furnace body, a loading system, an information collection system, and a combustion control system. The shear wall component 1 includes a shear wall body 1-2, shear wall loading beam 1-1 shear wall bottom pier 1-3, the furnace body consists of two shear wall members 1, furnace side wall 2-1, furnace roof 2-2 using bolts, Assembled by screws, the shear wall body 1-2 and two furnace side walls 2-1 form a vertical box-shaped space, and a furnace roof 2-2 is placed on the top of the vertical box-shaped space, and the furnace side The edge of the steel plate of the wall 2-1 and the furnace roof 2-2 is designed with reserved holes for bolts, and the upper edge of the steel plate of the furnace side wall 2-1 is welded and drilled Angle steel 2-1-2 and the edge of the furnace roof 2-2 are fastened with bolts , the bottom pier 1-3 of the shear wa...

Embodiment 2

[0033] Embodiment two: if Figure 5 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the furnace body is assembled by four shear wall components 1, furnace side walls 2-1, and furnace roof 2-2 using bolts and screws. As a result, the shear wall body 1-2 and the four L-shaped furnace side walls 2-1 form a box-shaped space, and correspondingly, two reaction frames need to be provided.

[0034] The working process of the present invention is:

[0035] During the test, first build the furnace side wall 2-1 and the furnace roof cover 2-2 according to the size of the fire shear wall specimen 1, and reserve holes and bolts for the thermocouple 8, the burner 11, and the flue 17 hole; then according to the specific embodiment of the furnace body one or two according to the test requirements, the shear wall component 1 and the furnace side wall 2-1 are hoisted in place, and the screw rod passes through the reserved hole on the furnace side wall, a...

Abstract

The invention discloses a shear wall fire exposure testing device under the vertical load effect, relates to a fire resistance testing device, and belongs to the technical field of building structure disaster prevention and reduction. The shear wall fire exposure testing device comprises a furnace body, a loading system, an information collection system and a combustion control system. The furnace body is formed by assembling a shear wall component, a furnace side wall and a furnace top cover through bolts and screws. The furnace side wall and the furnace top cover fix zirconium-containing refractory fiber modules to a steel plate by means of stainless steel anchoring parts. The assembling efficiency is high, the modifiability is good, the containment furnace wall can be modified according to different test piece sizes, the repeated utilization factor is high, waste is reduced, a vertical placement shear wall fire resistance test under the axial pressure is achieved, and real working conditions of test pieces can be simulated; an intelligent ratio adjuster and an electric actuator are used for achieving automatic control over the furnace temperature; the shear wall test piece and the furnace wall are combined into the furnace body, one or more shear walls can be synchronously tested, the test data discreteness is lowered, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of disaster prevention and mitigation of building structures, and in particular relates to a shear wall fire test device under the action of a vertical load. Background technique [0002] In recent years, the frequency of building fires has increased unabated, and the resulting losses have been shocking. Therefore, the research on the fire resistance of building components has attracted the attention of researchers. The fire resistance performance of building components is mainly obtained from the fire resistance test, that is, under the standard heating conditions, pressure conditions and other requirements, it is tested whether the building components meet the fire resistance performance requirements specified in the "Code for Fire Resistance Tests of Building Components" (GB / T 9978.1-2008). [0003] Reinforced concrete shear wall is one of the important components in high-rise buildings. When a fire occu...
