Technical Field

The invention relates to the technical field of concrete construction formworks, in particular to a formwork with built-in high-frequency vibration for concrete construction.

Background

Concrete is a heterogeneous brittle material formed by mixing gravel aggregate, cement, water and other additional materials. As numerous air bubbles appear on the surface and inside of the concrete, the apparent quality of the concrete is not only influenced, but also the concrete is not compact and has low strength. The main reasons for the generation of air bubbles inside and on the surface of the concrete are insufficient concrete vibrating time or vibration leakage, and air bubbles are not discharged. In the concrete pouring process, a vibration tool needs to be adopted to vibrate the concrete so as to improve the compactness of the concrete.

Usually, a vibrating rod is used for vibrating in the concrete pouring process, and for concrete with a larger plane or deeper, the effect of using the vibrating rod is limited, and bad conditions such as honeycomb pitted surface, cavities and the like are easy to occur; also have and apply the vibrational force to the concrete through the flat vibrator from the template outside and vibrate, but the flat vibrator needs interim installation, still need dismantle after having vibrated, uses inconveniently, influences on-the-spot efficiency of construction.

In addition, for the construction of large-volume concrete, a steel formwork for concrete molding is needed. The steel template is widely applied to building engineering due to the characteristics of repeated use, attractive concrete pouring and forming and the like, the concrete also needs to be compacted when the steel template is adopted for concrete construction, and the construction efficiency and the construction quality can be further improved if a reasonable vibration excitation device is adopted.

In order to achieve the purpose, the invention adopts the technical scheme that:

the template with built-in high-frequency vibration for concrete construction comprises a template body with an inner cavity, wherein the template body is provided with a bottom plate and a side plate, a main excitation component and an auxiliary excitation unit are arranged in the inner cavity, and excitation forces of the main excitation component and the auxiliary excitation unit act on the bottom plate; the main excitation assembly comprises a vibration plate arranged in parallel to the bottom plate, the periphery of the vibration plate is respectively connected with the side plates in a sliding mode through connecting rods, a plurality of first elastic supporting elements are arranged between the vibration plate and the bottom plate, one surface, facing the bottom plate, of the vibration plate is staggered with the first elastic supporting elements and provided with a plurality of excitation rods, excitation heads of the excitation rods are abutted to the inner surface of the bottom plate, and a main excitation source is arranged on the other surface of the vibration plate; an openable cover plate is further mounted on one side, far away from the bottom plate, of the side plate, and a buffering sound insulation layer is arranged on the inner surface of the cover plate.

This a template for concrete construction is through setting up main excitation subassembly and supplementary excitation unit in its inside, can produce high-frequency vibration and continuously act on the bottom plate, the concrete that makes the bottom plate outside pouring obtains the vibration that the high frequency lasts, is favorable to the concrete to improve the pouring effect and the speed of concrete, and the bubble that mix with in the abundant discharge concrete makes the closely knit bubble-free of concrete surface, reaches the effect of smooth mirror surface.

Because the components are arranged in the inner cavity of the formwork, the structure of the outer part of the formwork is not changed greatly, and the concrete pouring device can still adapt to concrete pouring in various construction environments; the template is of an integral structure, so that the template is convenient to integrally carry and set, when in use, vibration work can be carried out only by connecting a power supply and a signal wire, and complex motor installation and arrangement on a construction site are not needed, so that the construction time is saved; after the template is used, the template can be integrally detached for the next construction and use, and can be repeatedly used.

The main vibration excitation component enables the vibration plate to vibrate by arranging the main vibration excitation source on the vibration plate, so that all the vibration excitation rods are driven to regularly beat the bottom plate, the bottom plate is enabled to be comprehensively and regularly vibrated and linearly beaten, and the whole concrete surface is favorably compacted and exhausted; irregular resonance and large noise generated by directly mounting the main excitation source on the bottom plate are avoided, and the phenomenon that the vibration close to the main excitation source is obvious and the vibration far away from the main excitation source is weakened can also be avoided.

The arrangement of the plurality of first elastic supporting elements and the connecting rods can connect and support the vibration plate on one hand, and can limit the circumferential movement of the vibration plate on the other hand, so that the vibration plate is forced to reciprocate only along the axial direction of the bottom plate, and the axial action of the exciting force on the bottom plate avoids the noise and the vibration of the side plate caused by the impact to the periphery when the vibration plate vibrates;

the first elastic supporting element can also cooperate with the vibration plate and the vibration exciting rod to reciprocate, the connecting rods can slide on the side plates (in the direction perpendicular to the bottom plate), and the connecting rods arranged on the periphery of the vibration plate can just limit the vibration plate at the middle position in the template.

The template formed by combining the bottom plate, the side plates and the cover plate is convenient to open and close, can be used for installing and maintaining internal components, and can also form a concrete template with a regular outer contour.

The nylon head is adopted as the excitation head, so that the noise can be reduced, and the damage to the base plate caused by the long-term collision of the excitation head can also be reduced. The shape of the vibration plate may be selected according to the shape and size of the template.

Furthermore, a T-shaped sliding groove is formed in the inner side of each side plate, and at least one end of the T-shaped sliding groove in the sliding direction is provided with a dismounting opening; one end of the connecting rod is T-shaped or I-shaped and is sleeved in the T-shaped sliding groove in a sliding mode, and the other end of the connecting rod is provided with a connecting flange and is detachably connected to the middle of the side wall of the vibrating plate in a threaded mode.

By adopting the connection mode, the sliding of the connecting rod is facilitated, and when the vibrating plate vibrates, the connecting rod can axially slide in the T-shaped sliding groove without falling off the side plate, so that the middle position of the vibrating plate is ensured.

Furthermore, the inner contour surface of the T-shaped sliding groove is covered with a buffer layer, and the buffer layer is a vibration-damping rubber pad. The direct transmission of the vibration of the connecting rod to the side plate can be reduced, and the acting force applied to the T-shaped sliding groove by the connecting rod can be reduced and buffered.
