Technical Field

The invention relates to the technical field of building construction, in particular to a building construction safety prevention and control system and a prevention and control method.

Background

With the development of national economy and the promotion of urbanization in China and the vigorous development of large-scale construction projects in China, the project construction shows the characteristics of diversified investment main bodies, complicated technical process, novel building materials, independent and independent enterprises, large-scale construction project and the like, quality safety risks and safety problems in the construction projects are widely concerned, and construction safety accidents happen sometimes. The main injuries at the construction site are as follows: high-altitude falling, object striking, collapse, electric shock, lifting and mechanical injury, and the first time the high-altitude falling is performed, wherein the high-altitude falling comprises the falling of construction tools, construction materials and constructors. In the existing construction site, a formwork is mostly erected outside a building to protect constructors, and a protective net is supported at the bottom of the formwork or outside the formwork to prevent operators and logistics from falling. However, the falling objects are contained in the protective nets which are arranged in an opening mode in a prevention and control mode, the falling objects are large in momentum in the falling process, the falling objects are thrown out only through the protective nets, the protective nets rebound easily, and great potential safety hazards exist.

Disclosure of Invention

Aiming at the technical problem that the protective net is easy to bounce falling objects on the existing building construction site; the invention provides a building construction safety prevention and control system and a prevention and control method, which can trap high-altitude falling objects and prevent the high-altitude falling objects from falling for the second time so as to ensure the construction safety.

The invention is realized by the following technical scheme:

a building construction safety prevention and control system comprises a protective frame and a support frame, wherein the protective frame is used for supporting a protective net, the support frame is used for being fixedly connected with a building structure body or a formwork, and the protective frame is arranged above the support frame and can move up and down on the support frame; the support frame is provided with a damping assembly, and the damping assembly is used for controlling the damping size of the up-and-down movement of the protection frame.

When the protective device is used, the support frame is fixedly connected with a building structure body or a formwork, wherein the protective frame is supported on the support frame through the damping effect of the damping assembly, so that the protective net is supported below the construction operation platform, and objects falling from the operation platform are caught through the protective net. The protective frame is arranged above the supporting frame and can move up and down on the supporting frame, and when an object falls on the protective net, the protective frame is driven to move towards the supporting frame by the falling impact force; the damping assembly does work on the protection frame in the process that the protection frame moves down to absorb the kinetic energy of the protection frame and stop moving down until the protection frame, and sufficient buffering is provided for falling objects, so that the falling objects are held in a pocket and the falling objects are prevented from falling for the second time, and the construction safety is ensured.

As a specific implementation mode of connecting the protection frame and the support frame, each corner of the protection frame is provided with a sliding rod, the support frame is provided with a plurality of sliding cylinders, and the sliding rods are inserted in the sliding cylinders so as to connect the protection frame and the support frame in a sliding manner.

Preferably, a return spring is further sleeved outside the sliding rod and used for driving the protection frame to reset. On one hand, in the process of moving the protection frame downwards, the reset spring can absorb partial impact of the protection frame so as to reduce the downward movement stroke of the protection frame and further reduce the volume of the prevention and control system; on the other hand, after the falling object on the protection frame is removed, the damping size of the damping assembly is reduced, the protection frame is driven to reset through the reset spring, and the prevention and control of the building construction safety prevention and control system can be quickly recovered.
