Forming device for circular-truncated-cone-shaped elevation concrete block for floor slab

Abstract

The invention discloses a forming device for a circular-truncated-cone-shaped elevation concrete block for a floor slab. The forming device comprises two parallel clamping plates. A plurality of half circular truncated cone ring plates are arranged on the opposite sides of the clamping plates. The ring plates are paired between the two clamping plates to form a circular-truncated-cone-shaped die. A bed board on the side opposite to the corresponding ring plate is vertically arranged at the bottom of each clamping plate, and the two clamping plates are connected through at least two sets of paired bolts and nuts. According to the forming device, cavities can be formed between the clamping plates and the ring plates through a two-point connecting structure, when the clamping plates are knocked, vibration waves can be formed between the ring plates and the clamping plates through the knocking action, the ring plates are vibrated through the vibration waves, demoulding is facilitated, and in other words, an operator can finish demoulding with small knocking force; and the labor force input is reduced, the demoulding efficiency is greatly improved, knocking on the die is reduced, and accordingly the service life of the die is prolonged.

Description

technical field [0001] The invention relates to the field of floor elevation in the construction field, in particular to a forming device for a conical elevation concrete block of a floor. 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 in winter).
