Pressure-resistant buffering steel formwork mechanism for roads and bridges and buffering method thereof

Abstract

The invention discloses a pressure-resistant buffering steel formwork mechanism for roads and bridges and a buffering method thereof. The pressure-resistant buffering steel formwork mechanism comprises a formwork base, pressure-resistant plates arranged above the formwork base at certain intervals, a first buffer spring arranged between the formwork base and the pressure-resistant plates, an abutting push rod vertically arranged on the formwork base in a sliding mode, a transmission assembly arranged between the abutting push rod and the pressure-resistant plates, and a second buffer spring arranged above the abutting push rod. The pressure-resistant plates are buffered through the first buffer spring when being subjected to external stamping, so that the pressure of the template base is effectively reduced, the abutting push rod is driven to move upwards through the transmission assembly in the process that the pressure-resistant plates are stressed and pressed downwards, and the pressures of the pressure-resistant plates are released under buffering and impacting of the second buffer spring. Therefore, the steel formwork mechanism has the effect of multiple times of buffering, and the compression resistance effect of the steel formwork mechanism is greatly improved.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a buffering steel formwork mechanism for compressive roads and bridges and a buffering method thereof. Background technique [0002] Steel formwork is a steel formwork used for concrete pouring. In the process of road and bridge construction, some columnar steel formwork is often used for concrete pouring. After the concrete is poured inside the columnar steel formwork, since the concrete is fluid before solidification, the steel formwork The pressure at the bottom is generally high, and during the solidification process of the concrete, it bears the gravity above for a long time, so the compressive performance of the steel formwork is particularly important. [0003] However, the traditional steel formwork mostly improves the compressive capacity of the formwork by adding steel bars. This method makes the force of the formwork uneven. When the concrete is su...

[0003] However, the traditional steel formwork mostly improves the compressive capacity of the formwork by adding steel bars. This method makes the force of the formwork uneven. When the concrete is subjected to external forces, it is prone to local pressure increase, which affects the building shape. The effect, and the assembly and adjustment of the steel plate formwork is inconvenient, and the service life is short
