Abstract

The invention relates to a formula of imitative wood filling slurry of a building formwork supporting keel and a processing method. The formula comprises reclaimed rubber powder, plant fibers, hydraulic cementing materials, an additive agent and water. The processing method comprises the following steps of: (1) detecting and adjusting the particle size of the reclaimed rubber powder to accord with a combination requirement for later use; (2) carrying out immersion treatment on sawdust or pulverized matters of crop platycodon grandiflorum by using antiseptic oil or coal tar or anthracene oil for later use; (3) firstly, placing the reclaimed rubber powder, the plant fibers and the hydraulic cementing materials processed for later use in a high-speed mixing device according to the proportion of the components, adding water and the additive agent after mixing for 2-3 minutes, mixing for 2-3 minutes again to prepare the imitative wood filling slurry for the building formwork supporting keel. The imitative wood filling slurry has the remarkable advantages of low cost, high strength and convenience for processing.

Description

technical field [0001] The invention belongs to the technical field of metal-reinforced concrete structure formwork support structure, especially the formula and processing method of building formwork support keel imitation wood filling slurry. Background technique [0002] In construction engineering, the key to the forming quality of reinforced concrete structures lies in the formwork installation quality, and the key to the formwork installation quality lies in the formwork support system. To ensure the strength, stiffness and stability of the formwork support system, the support poles, keels and connectors in the support system play a decisive role. The support keel transmits the load from the formwork to the support pole, and its strength, stiffness and stability directly affect the quality of formwork installation and the performance of its functions. [0003] At present, the keels of the formwork support system in engineering practice include shaped steel keels, wood...
