Abstract

The invention discloses a high-performance concrete extrusion partition plate connection member and a preparation method, comprising the following raw materials: cement, gesso, fly ash, quartz sand, mekralon, water reducer, water-retaining agent and water. The raw materials of the connection member, after mixing and stirring, are orderly extruded by a high pressure and vacuum extruder. The partition plate connection member prepared through forming treatment and twice maintenance treatment has high intensity, and an ultimate flexural capacity and compressive strength exceeds a government standard. The connection member has advantages of small drying shrinkage, low expansion and contraction ratio, high distortion-resistant performance, aging resistance, water proof, fire proof and sound insulation. After the connection member is connected with the partition plate, no crack and no shedding are generated between the connection member and the partition plate, and the connection member accords with installation requirement, and reaches requirement of a government standard of lightweight batten for construction (GB / T 23451-2009).

Description

technical field [0001] The invention relates to a building material and a preparation method thereof, in particular to a special part of an easily disassembled partition wall and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Reinforced concrete structure is one of the most widely used building structures in modern times. In addition to the quasi-static load on the structure, the accidental load on the structure must also be considered during the design process, including impact, explosion, combustion, etc. [0003] At present, there are many kinds of connecting components (also known as columns) for installing partition panels used on the market, and their shapes are different (such as figure 1 ). Connecting members are divided into metal connecting members, concrete connecting members, etc. according to their composition. The disadvantages of existing partition board connecting members are as follows: ...
