Fabricated cement board force transmission component, cement board and preparation and construction method of cement board

Abstract

The invention relates to the technical field of assembly type pavements and particularly relates to an assembly type cement board force transmission component, a cement board and a preparation and using method of the cement board. The force transmission component comprises a guide plate and a plurality of launching sleeves perpendicularly and fixedly connected with the guide plate, wherein the guide plate is provided with a plurality of guide holes, the launching sleeves communicate with the guide holes, elastic force transmission rod assemblies are arranged in the launching sleeves, and blocking parts for blocking the elastic force transmission rod assemblies are arranged on the side, away from the launching sleeves, of the guide plate; a targeting sleeve is arranged on the side, away from the launching sleeve, of the blocking part, located on the side, in the moving direction of the elastic dowel bar assembly, and collinear with the launching sleeve. The force transmission component is advantaged in that the elastic dowel bar assembly can be quickly installed on the premise that an upper surface of a prefabricated slab joint is not damaged basically, and overall flatness and attractiveness of a pavement are guaranteed.

Description

technical field [0001] The invention relates to the technical field of assembled pavements, in particular to an assembled cement board force transmission member, a cement board and a method for preparing and using the same. Background technique [0002] Cement concrete pavement plays a dominant role in airport road paving, and its construction is divided into cast-in-place method and prefabricated assembly method. The traditional cast-in-place method has the problems of extensive production, low efficiency, and difficult control of construction quality caused by pouring and paving on the construction site, while the prefabrication assembly method has the advantages of centralized prefabrication quality controllable, transparent batch transportation management, and fast and environmentally friendly on-site assembly . Based on the above advantages, precast concrete pavements are widely used in various places, but the joints of rigid pavements need to ensure good load transfer...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the distance between the joints between the panels and the flatness of the panel surface require that the operating space for the installation of the force transmission member should not be too large, and there are many joints in the prefabricated panels, and the force transmission components with slots on the upper surface are arranged in a large area. Under the circumstances, it is bound to destroy the surface texture and overall flatness of the prefabricated slab; if the thin layer of concrete covered on the surface of the notch is not handled properly, the concrete around the force-transmitting member will be easily cracked and broken under the action of load and environment, and the exposed edges and corners of the steel force-transmitting member It will have a serious impact on the high-speed vehicle tires on the pavement. In addition, the exposed force-transmitting components will also rust quickly under rainwater immersion, causing a rapid decline in the load-transfer performance between prefabricated panels.
