Description

Technical Field

[0001] This utility model belongs to the technical field of fire resistance testing devices, specifically relating to a fire resistance testing frame. Background Technology

[0002] Fire resistance is a crucial performance characteristic of building components. Good fire resistance allows building components to maintain their structural function during a fire and confine the fire to a limited space, ensuring the building's fire safety. The fire resistance performance of building components can be obtained by performing a full-scale fire resistance limit test. During the full-scale fire resistance limit test, the sample to be tested (fire doors, fire windows, fire shutters, firewalls, etc.) must first be mounted on a dedicated fire resistance test frame. Then, the dedicated fire resistance test frame is fixed to the fire resistance test furnace before the fire resistance limit test is performed. Currently, there is a lack of a new type of fire resistance test frame that facilitates its own fixation to the fire resistance test furnace. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a novel refractory test frame that can be easily fixed to a refractory test furnace.

[0004] The present invention adopts the following technical solution: A fire resistance test frame includes a frame body; the frame body has a cavity for arranging the test sample; the frame body is provided with a first support column for fixing the frame body to a fire resistance test furnace; the frame body is provided with a plurality of lifting lugs for hoisting.

[0005] Furthermore, a first bearing is provided on the first support column.

[0006] Furthermore, the lifting lug device includes a lifting lug plate, which is provided with a plurality of lifting lug holes for lifting.

[0007] Furthermore, reinforcing plates are provided at the corners of the main frame body.

[0008] Furthermore, the main body of the frame is an iron frame or a steel frame.

[0009] Furthermore, the wall thickness of the main frame body is 3mm to 50mm.

[0010] Furthermore, the interior of the frame body is filled with concrete or aluminum silicate fiber cotton.

[0011] Furthermore, a second pillar is also provided on the main frame body, which is used by the mobile vehicle to transfer the main frame body.

[0012] Furthermore, a third pillar is also provided on the main frame, which is used by the mobile vehicle to transfer the main frame.

[0013] Furthermore, a second bearing is provided on the third support column.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a fire resistance test frame, the main body of which is provided with a cavity for arranging the test sample. When a fire resistance test is required, the test sample is fixed in the cavity. After a certain period of time, the main body of the frame is transferred (e.g., by using a crane to lift the lifting lug device) to the fire resistance test furnace and fixed. The main body of the frame is fixed to the fire resistance test furnace by a first pillar (e.g., fixed to the support of the fire resistance test furnace), thus achieving rapid fixation of the main body of the frame.

[0015] The present invention provides a fire resistance test frame, which can be easily fixed to the fire resistance test furnace via a first support column. Attached Figure Description
