Description

Technical Field

[0001] The utility model relates to the technical field of edge protection in building construction, in particular to an edge protection structure, and more particularly to an edge protection structure for a hole opening. Background Art

[0002] As the country continues to increase the implementation of energy conservation, emission reduction and green mountains and clear waters, more and more enterprises and institutions are promoting the work concept of "reducing costs and increasing efficiency". How to achieve effective breakthroughs in "reducing costs and increasing efficiency" from subtle and routine aspects is the common goal of everyone. For construction companies, the construction site has a higher potential to explore low-carbon and energy-saving construction processes or methods. At the same time, the construction industry in my country is a high-risk industry. In the window period of rapid economic development, safety issues cannot be ignored. Therefore, safety must be put first on the road to promoting low-carbon energy conservation.

[0003] In construction work, falling from height is one of the most frequent safety accidents. How to do a good job of horizontal protection of edges and openings and effectively implement protective measures is also an important issue on the construction site. For example, there is no reliable hanging point for the safety belt of the edge operation, there is no soft protection at the horizontal opening of the atrium or the protective measures are not in place, there will be the risk of falling from height.

[0004] Traditional safety protection measures are complicated to set up. Most of them are just for the sake of simplifying the procedures and do not play a protective role. In addition, the safety protection measures have shortcomings such as unreliable connection and poor stability. For this situation, we provide an edge protection structure. Starting from safety, green and low carbon, material turnover, standardized production and mass production, we make full use of the inner section of the three-section tie screw used to fix the edge beam formwork during the construction process, that is, to connect the inner rod to install the protection structure, thereby solving the safety protection problem of edge operations. Utility Model Content

The technical solution is as follows:

[0006] A structure for protecting an edge, comprising a plurality of connecting inner rods penetrating through a tunnel edge beam, wherein both ends of the connecting inner rods are threadedly connected with pull-ring screws, a steel wire rope is fixedly connected between the plurality of pull-ring screws located on the inner side of the tunnel edge beam, a safety buckle hook of a safety belt is hung on the steel wire rope, and a plurality of pull-ring screws located on the outer side of the tunnel edge beam and a plurality of pull-ring screws on the outer side of the tunnel edge beam on the opposite side are connected to a safety net; the connecting inner rod is the middle section of a three-section tension screw used in the construction process, and the safety buckle hook of the safety belt is hung on the steel wire rope for convenience of movement by workers, thus avoiding the problem of the safety belt being hung at a fixed point and causing the safety belt to remain unchanged in movement; the safety belt and the safety net are both installed and fixed by using the connecting inner rods remaining after removing the connecting outer rods at both ends of the three-section tension screw, which not only saves materials but also is relatively stable after installation.

[0007] Furthermore, sleeves are fixed at both ends of the connecting inner rod, and the other end of the sleeve is threadedly connected to one end of the pull ring screw, so that the sleeve is convenient for installing or replacing the pull ring screw.

[0008] Furthermore, the sleeve outer shell is provided with a stop rubber pad, and the rubber pad is convenient for fixing the inner rod to prevent it from moving.

[0009] Furthermore, the stopping rubber pad is in a truncated cone shape, and the large circular surface of the stopping rubber pad faces the outside of the edge beam and is tightly attached to the inner side surface of the edge beam template.

[0010] Furthermore, an L-shaped plate is connected to the straight rod section of the pull ring screw, and the L-shaped plate is a right-angle plate, and one outer side surface of the L-shaped plate is in contact with the wall surface of the side beam of the opening, and a connecting clip is fixed on the other outer side surface of the L-shaped plate, and the connecting clip can be clipped onto the straight rod section of the pull ring screw. The L-shaped plate can provide a certain supporting force for the pull ring screw to prevent the pull ring screw from being deformed when an object falls onto the safety net.

[0011] Furthermore, the connecting clamp is arranged axially along the pull ring screw, the cross-section of the connecting clamp is arc-shaped and the edges on both sides are bent outwards, and the edges of the connecting clamp are bent outwards to facilitate clamping to the straight rod section of the pull ring screw.

[0012] Furthermore, the connecting clamp is an elastic member.

[0014] Furthermore, steel wire ropes are tied between several pull ring screws on the outer side of the opening edge beam and horizontally interwoven into a net. The safety net is laid on the interwoven steel wire ropes. The steel wire ropes are tied into a net, which indirectly enhances the tolerance of the safety net and prevents the impact force of the object from being fully applied to the safety net when an object falls, making the safety net more easily damaged.

[0015] The beneficial effect of the technical solution provided by the embodiment of the utility model is that the device uses the middle section of the three-section tension screw cast inside the edge beam during the construction process to connect the inner rod to install the edge protection structure, which is not only safe and reliable, quick to install and disassemble, and easy to operate, but also can be used in a turnover manner to fully achieve the effect of "reducing costs and increasing efficiency";
