Description

Technical Field

[0001] The utility model relates to the technical field of pressure simulation experimental equipment, in particular to a pressure simulation experimental device for cast-in-place dense-rib cavity floor slabs. Background Art

[0002] The floor composed of intersecting beams (main beams and secondary beams) and plates is called a ribbed floor. The dense ribbed floor is composed of thin plates and ribbed beams with small spacing between plates. It is divided into one-way dense ribbed floor and two-way dense ribbed floor. The dense ribbed floor is generally used in situations where the span is large and the beam height is limited. When the column grid size of the building is square or close to square, the two-way dense ribbed floor is often used. The hollow ribbed floor usually needs to be pressure tested before it is put into use to prevent it from being insufficiently strong and posing a safety hazard.

[0003] For example, a traditional solution: a pressure simulation experimental device for a hollow floor with dense ribs (Announcement No.: CN213544228U), the device includes a top plate, a connecting plate is fitted and connected in the middle of the lower surface of the top plate, an electric push rod is fixedly connected in the middle of the lower surface of the connecting plate, a pressure plate is fixedly connected at the lower end of the electric push rod, and pressure sensors are inlaid at the four corners of the lower surface of the pressure plate, and a cavity is horizontally opened inside the top plate, and a threaded rod is horizontally arranged in the inner cavity of the cavity. The utility model is provided with a threaded rod and a threaded sleeve in the inner cavity of the cavity, the threaded sleeve is movably sleeved on the outer side of the threaded rod, and the upper surface of the base is fitted and connected with an L-shaped groove plate, the rotation of the threaded rod can drive the threaded sleeve to slide horizontally, and the L-shaped groove plate can slide horizontally on the upper surface of the base, so the device can apply pressure to various positions on the upper surface of the hollow floor with dense ribs, thereby avoiding safety hazards caused by the lack of pressure detection in some areas.

[0004] When the device is in use, although the pressure sensor can perform horizontal reciprocating motion to adjust different positions of the multi-ribbed hollow floor, since the operating trajectory of the pressure sensor is on the same straight line, that is, the pressure sensor of the device can only be adjusted in the X-axis direction but not in the Y-axis direction, it is not possible to perform pressure detection on different positions of the multi-ribbed hollow floor, and the use of the device is limited.
