Destructive test method for hollow floor gypsum filling box

Abstract

The invention discloses a destructive test method for a gypsum filling box of a hollow floor. The method comprises the steps: step 1, making test preparation; step 2, preparing a gypsum filling box; step 3, carrying out damage detection; to be specific, cutting the hollow floor formed by the concrete layer with the strength reaching over 50% to obtain two gypsum mold boxes serving as test objects,observing the tangent planes, and weighing the weights of the gypsum mold boxes; step 4, comparing, observing and recording a test phenomenon; step 5, carrying out test analysis; and step 6, obtaining a test conclusion. With the method, the phenomena of horizontal displacement and upward floating of the gypsum filling box during concrete pouring can be well controlled; the sectional dimension ofeach component and the thickness of the reinforcing steel bar protective layers of the upper and lower plates are ensured to meet the specification and design requirements and the compactness of concrete at the lower part of the gypsum filling box is ensured; the problem of concrete quantity increase caused by damage of the gypsum filling box in the concrete pouring and vibrating process is conveniently solved. The construction process is simple and quick.

Description

technical field [0001] The invention relates to a building test, in particular to a destructive test method for a hollow floor gypsum filling box. Background technique [0002] The hollow floor is a cast-in-place reinforced concrete hollow floor; also called the cast-in-place beamless hollow floor, the hollow beamless floor is cast in place after installing the core mold product. The hollow floor cover comprises steel bars, concrete and core moulds, the core moulds are embedded in the reinforced concrete, and the core mould is characterized in that the core moulds are filled with light materials. [0003] The hollow floor has many advantages, saving building materials, especially suitable for large-span and large-space buildings, two-way grid cast-in-place rib force transmission system, reducing the weight of the floor, flexibility and humanization of space, a real flat plate, There is no need for a ceiling, the building energy saving effect is good, the construction is con...

Problems solved by technology

[0004] In the hollow floor, it is often necessary to use the gypsum filling box for construction. During the construction of the gypsum filling box, it is necessary to conduct a destructive test to observe the construction effect to ensure the construction quality. However, most of the destructive tests on the gypsum filling box are currently Based on construction experience, there is no systematic and complete set of methods
