[0002] During floor construction, holes are often reserved on the floor for material transportation, structure installation, etc., and the holes are closed after use. In order to ensure the safety of construction, protective plates are usually placed on the holes.

[0003] Chinese invention patent application CN116971634A discloses a safety protection construction method for horizontal openings on floors. During the arrangement of floor steel bars, load-bearing steel bars are arranged vertically and horizontally at the horizontal openings to form a steel mesh, and plywood is arranged on the steel mesh. The ends of the load-bearing steel bars extend into the floor steel bars and are fixed together with them. Later, concrete is poured to fix the load-bearing steel bars and the floor to form a whole, thereby supporting the plywood to form a safety protection structure for the horizontal openings on the floors. When the horizontal openings need to be constructed later, the plywood and the load-bearing steel bars can be removed. The load-bearing steel bars of the safety protection net are pre-buried in the floor and fixed to the floor steel bars, which is inconvenient to disassemble and assemble, and the fixed structure cannot meet the temporary use requirements of the horizontal openings. Therefore, it is necessary to provide a mesh protection device for the construction of the floor openings, which can solve the problem that the protection net is inconvenient to disassemble and assemble and cannot meet the temporary use requirements of the openings in the prior art.

[0020] The transverse ribs are connected between the wall 7 and the floor 6 through the embedded parts 1 and the fixing holes 4, and the other end of the transverse ribs is locked by the locking parts 3; the longitudinal ribs are connected through a pair of embedded parts 1 arranged at both ends of the opening 5, and the two ends of the longitudinal ribs are locked by the locking parts 3, so that the transverse ribs and the longitudinal ribs cross on the opening 5 to form a protective mesh 2, which plays a protective role. The transverse ribs and the longitudinal ribs are installed in a detachable manner, which is easy to disassemble to meet the temporary use requirements of the opening 5.

[0021] Preferably, the transverse reinforcement and the longitudinal reinforcement can be made of C12 steel bars, the arrangement spacing of the transverse reinforcement and the longitudinal reinforcement can be determined according to the protection requirements, and the arrangement quantity of the transverse reinforcement and the longitudinal reinforcement can be determined according to the size of the opening 5.

[0022] Please see attached Figure 1 and attached Figure 2 One end of the embedded part 1 is embedded in the floor 6, and the other end of the embedded part 1 is located above the floor 6 and forms a ring-shaped part 101. The ends of the transverse ribs and longitudinal ribs of the protective mesh 2 can pass through the ring-shaped part 101, and the locking part 3 is pressed against an end surface of the ring-shaped part 101 away from the opening 5.

[0023] The inner diameter of the ring 101 is slightly larger than the diameters of the transverse ribs and the longitudinal ribs, ensuring that the ends of the transverse ribs and the longitudinal ribs can match and penetrate the ring 101, and are not easy to shake after installation.

[0024] The locking member 3 is pressed against the outer side of the annular member 101, i.e., the end face away from the hole 5, and can provide tension for the transverse and longitudinal ribs, so that the transverse and longitudinal ribs are relatively fixed to the embedded member 1, thereby achieving installation and fixation of the transverse and longitudinal ribs.

[0025] The height of the annular member 101 connected to the transverse ribs is lower than the height of the annular member 101 connected to the longitudinal ribs, so that the longitudinal ribs overlap the transverse ribs to form a protective mesh 2.

[0026] The height of the annular member 101 is adjusted by the embedded depth of the embedded member 1 to avoid interference between the transverse ribs and the longitudinal ribs, thereby ensuring the forming of the protective mesh 2. Preferably, the transverse ribs overlap the longitudinal ribs vertically.

[0027] Please see attached Figure 1 and attached Figure 2 The protective mesh 2 is made of a plurality of transverse ribs and a plurality of longitudinal ribs cross-connected, the length of the transverse ribs is greater than the transverse width of the opening 5, and the length of the longitudinal ribs is greater than the longitudinal width of the opening 5, so as to ensure that the transverse ribs and the longitudinal ribs can cross the opening 5 and play an effective protective role.

[0030] The fixing hole 4 is an internal thread hole, or the fixing hole 4 has an internal thread sleeve built in it.

[0031] During the construction of the wall 7, an internal thread hole can be reserved or an internal thread sleeve can be embedded in the reserved hole to facilitate the screw connection with the threaded section at one end of the transverse reinforcement, making disassembly and assembly convenient and flexible.

[0032] If the opening 5 is not connected to the wall 7, embedded parts 1 are arranged on the floor 6 along the circumference of the opening 5, and both ends of the transverse and longitudinal reinforcements are tied through the embedded parts 1 and locked through the locking parts 3 to cross the opening 5. The transverse and longitudinal reinforcements cross to form a protective mesh 2 and cover the opening 5 to play a protective role.

[0033] Please see attached Figure 1 and attached Figure 2 , the installation and disassembly method of the utility model is:

[0034] When the floor 6 is constructed, the embedded parts 1 are embedded in the floor 6 along the edge of the opening 5, and the number and spacing of the embedded parts 1 are determined according to the number and spacing of the transverse ribs and longitudinal ribs of the protective mesh 2. The embedded parts 1 can be made of steel bars, and the top of the steel bars is bent to form a ring part 101, and the inner diameter of the ring part 101 can be determined according to the diameters of the transverse ribs and longitudinal ribs.

[0035] During the construction of the wall 7 , an internal threaded sleeve is pre-buried at a position adjacent to the wall 7 and the opening 5 to form a fixing hole 4 .

[0036] The threaded section at one end of the transverse rib of the protective mesh 2 is screwed into the fixing hole 4, and the other end of the transverse rib passes through the annular member 101, and the nut, i.e., the locking member 3, is screwed on, and the nut is tightened on the side of the annular member 101 away from the hole 5, so that the transverse rib is fixed between the wall 7 and the floor 6. All transverse ribs are arranged and installed at intervals in the same way, which will not be repeated here.

[0037] The threaded ends of the longitudinal ribs of the protective mesh 2 are passed through the annular parts 101 of the two oppositely arranged embedded parts 1, and the nuts, i.e., the locking parts 3, are screwed on, and the nuts are pressed against the side of the annular parts 101 away from the opening 5, so that the longitudinal ribs are fixed on the floor 6 and intersect the transverse ribs perpendicularly. All longitudinal ribs are arranged and installed at intervals in the same way, which will not be repeated here.

[0038] The transverse ribs and the longitudinal ribs form a protective mesh 2 with a mesh structure, and the installation of the protective mesh 2 is completed.

[0039] When the longitudinal ribs need to be removed, the locking pieces 3 at both ends of the longitudinal ribs are unscrewed to pull out the longitudinal ribs. When the transverse ribs need to be removed, the locking piece 3 at the other end of the transverse ribs is unscrewed, and then one end of the transverse ribs is unscrewed out of the fixing hole 4 to pull out the transverse ribs.
