Technical Field

The invention relates to a construction anti-falling net for building engineering and a construction method thereof.

Background

The construction engineering major is mainly responsible for teaching and management of the civil engineering major construction engineering direction. The basic theory and the basic knowledge of engineering mechanics, soil mechanics, surveying, building construction and structural engineering subjects are mainly developed and mastered. It is a general term for various buildings and engineering facilities providing material and technical foundation for human life and production.

When the building is constructed, the height of a floor is gradually increased, and when the outer wall is operated, the building has certain danger.

Therefore, the anti-falling net for the building engineering construction and the building method thereof are designed, wherein the anti-falling net can be built at the periphery of a building body, and can buffer falling personnel when falling occurs, so that the injury is reduced.

Disclosure of Invention

The invention aims to provide a falling prevention net for building engineering construction and a building method thereof, wherein the falling prevention net can be built at the periphery of a building body, and can buffer falling personnel to reduce injury when falling occurs.

In order to solve the problems, the invention adopts the following technical scheme:

a construction anti-falling net for building engineering comprises more than two paired module components, a nylon net assembled between two adjacent module components, and a lateral protective net matched between two adjacent module components;

the module component comprises a front main frame rod and a rear main frame rod, wherein a connecting steel plate is matched with the main frame rods, a collision bolt is matched between the connecting steel plate and the building body, a rotating seat is arranged on one side, away from the building body, of the connecting steel plate, a pin shaft is matched between the main frame rods and the rotating seat, the main frame rods can rotate along the pin shaft, an inclined strut is welded at the bottom of each main frame rod, close to the connecting steel plate, and is 30-60 degrees relative to the inclination angle of the main frame rod, a check ring is processed on each inclined strut, a spring for supporting and buffering is assembled through each inclined strut, the local part of the spring extends to the outside of each inclined strut, one end, away from each inclined strut, of the spring abuts against the connecting steel plate, and the included angle between the upper end face of each main frame rod and the vertical face of the building body; the top of the main frame rod is provided with two through holes which vertically penetrate through, a movable supporting rod is arranged in each through hole, a first check ring is arranged outside each movable supporting rod, a first spring is sleeved on each movable supporting rod, and the first spring acts between each first check ring and the main frame rod; the upper end of the movable support rod is in threaded connection with an end cover, the upper end of the end cover is fixedly glued with a capsule ball made of rubber, and a hollow air cavity is formed inside the capsule ball; the outer side of the nylon net is sewn with a blank holder, four corners of the blank holder are provided with metal rings, and the metal rings are sleeved on the movable support rod and are clamped between the first check ring and the end cover; the lower end of the movable supporting rod is in threaded connection with a limiting nut;

the lateral protective net is connected between the left ends of the front main frame rod and the rear main frame rod, and screws are matched between the lateral protective net and the main frame rods.

Preferably, two side barrier strips are arranged on the left and right sides of the surface of the nylon net in parallel, a first side barrier strip is arranged between the side barrier strips on the two sides of the surface of the nylon net, the first side barrier strip is perpendicular to the side barrier strips, meanwhile, the height of the first side barrier strip is lower than that of the side barrier strips, the cross sections of the side barrier strips and the first side barrier strips are semicircular, and the side barrier strips and the first side barrier strips are made of soft materials; after the human body falls onto the protective net, the main frame rod can compress the spring to buffer the impact force when the human body falls down, and the damage to the nylon net is reduced. The adoption of side blend stop and first side blend stop for the human body rolls occasionally the separation on the nylon wire, reduces the health after falling from the building and rolls, reduces because the secondary injury that rolls and bring.

Preferably, the soft material is rubber or latex.

Preferably, a bottom buffer device is arranged between the front main frame rod and the rear main frame rod, when the nylon net deforms downwards too much, the nylon net contacts the bottom buffer device, and the middle position of the bottom buffer device can be bent downwards to collapse and absorb energy; when the floor when personnel fall is higher, the degree of depth that solitary nylon net collapses downwards is great, because the degree of depth of collapsing is great, can lead to human body to take place the health of great degree and buckle on the nylon net, and the emergence of this kind of buckling leads to the fracture of vertebra very easily, leads to comparatively serious consequence. After the bottom buffer device is adopted, the bottom buffer device can absorb energy and can limit the position below the nylon net, so that excessive deformation of the nylon net is avoided.

After the nylon net collapses downwards, personnel contact the energy absorption sleeve through the nylon net, and the energy absorption sleeve carries out secondary energy absorption after deformation and simultaneously is in soft contact with the human body, thereby reducing the injury. And the inner tube is disconnected, and its intermediate position department can rotate downwards, and during the rotation, need overcome the elasticity of second spring, the biggest bending that the inner tube can play to the spacing stay cord that sets up simultaneously forms, avoids the second spring to break away from the inner tube, has also avoided the condition appearance that can't form the support to the nylon wire after the inner tube disconnection simultaneously. The survival rate when the above-mentioned structure great promotion falls building incident and takes place to and can reduce the health damage to minimum.

A building method of a construction anti-falling net for building engineering comprises the following steps:

step 1: firstly, two module components are matched with more than one nylon net to form a unit, and in the unit of the components, more than one nylon net is stacked up and down; two adjacent units are staggered in the vertical space, and the unit part positioned below is positioned below the unit positioned above;
