Formwork with built-in high-frequency vibration for concrete construction

Abstract

The invention discloses a formwork with built-in high-frequency vibration for concrete construction, which includes a bottom plate and a side plate, a main vibration excitation component and an auxiliary vibration excitation unit, and the excitation of the main vibration excitation component and the auxiliary vibration excitation unit is The vibration force acts on the bottom plate; the main vibration component includes a vibration plate arranged parallel to the bottom plate, and the four sides of the vibration plate are slidingly connected with the side plates through connecting rods, and the vibration plate and the side plate A number of first elastic support elements are arranged between the bottom plates, and the side of the vibrating plate facing the bottom plate is staggered from the first elastic support elements, and a number of excitation rods are provided, and the excitation heads of the vibration rods abut against The inner surface of the bottom plate and the other side of the vibrating plate are equipped with a main excitation source; the formwork used in this application can generate high-frequency vibrations to continuously act on the bottom plate to fully discharge the air bubbles contained in the concrete, so that the concrete surface is dense and free of vibration. Air bubbles to achieve a smooth mirror effect.

Description

technical field [0001] The invention relates to the technical field of concrete construction formwork, in particular to a formwork with built-in high-frequency vibration for concrete construction. Background technique [0002] Concrete is a heterogeneous brittle material formed by mixing sand and gravel aggregates, cement, water and other external materials. Due to the appearance of many air bubbles on the surface and inside of the concrete, not only the apparent quality of the concrete is affected, but also the concrete is not dense and the strength is low. The air bubbles inside and on the surface of the concrete are mainly caused by insufficient concrete vibration time or vibration leakage, and the air bubbles are not discharged. During the concrete pouring process, vibrating tools are required to vibrate the concrete to improve the compactness of the concrete. [0003] Usually, vibrating rods are used to vibrate during the pouring of concrete. For large flat or deep co...

Problems solved by technology

[0003] Usually, vibrating rods are used to vibrate during the concrete pouring process. For large flat or deep concrete, the effect of using vibrating rods is limited, and it is prone to harsh conditions such as honeycomb pockmarks and cavities; Vibration force is applied to the concrete externally to vibrate, but the flat vibrator needs to be installed temporarily, and needs to be dismantled after the vibration is completed, which is inconvenient to use and affects the efficiency of on-site construction
