Production technology for circular-truncated-cone-shaped elevation concrete block for floor slab

Abstract

The invention discloses a production technology for a circular-truncated-cone-shaped elevation concrete block for a floor slab. The production technology comprises the steps of the preparing stage, the pouring stage, vibration forming, connecting piece setting, forming form removal and the like. According to the production technology for the circular-truncated-cone-shaped elevation concrete block for the floor slab, vibration waves can be formed between ring plates and clamping plates under the knocking action, the ring plates are vibrated through the vibration waves, demoulding is facilitated, in other words, an operator can finish demoulding with small knocking force, labor force input is reduced, and the demoulding efficiency is greatly improved; and meanwhile, knocking on a die is reduced, and accordingly the service life of the die is prolonged; the distance between connecting columns and wedge-shaped blocks is 81%-84% of the length of ring plate bevels; and resonance is most easily generated between the ring plates and between the ring plates and the clamping plates, and the demoulding efficiency is the highest in the resonance state. Equal-height blocks manufactured through the method can be used for wood templates and steel templates, corresponding technologies can be adopted for the two different templates, and high universality is achieved; and the demoulding operation is conducted according to the set sequence, and the superior product rate of products can be increased to 90% or above.

Description

technical field [0001] The invention relates to the field of floor elevation in the field of construction, in particular to a production process of a conical elevation concrete block used for floor slabs. Background technique [0002] Cast-in-place reinforced concrete floor slabs refer to the floor slabs manufactured on site according to the design position, by setting up formwork, binding steel bars, pouring concrete, curing, and removing formwork. Floor maintenance and form removal requirements: [0003] 1. The strength of concrete with a span of more than 8 meters is ≥100%, and the formwork can only be removed when the concrete strength is ≥75% for spans of 8 meters or less; when the concrete strength is ≥1.2MPa, the floor can be used for construction. (Generally, the strength can reach ≥1.2MPa 24 hours after watering, and it can take 7 to 9 days under normal maintenance in spring, summer and autumn; the formwork can be removed in 10 to 15 days under normal maintenance i...
