Example 1
Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1-5 illustrate the roofing structure in its entirety. Fig. 1 is a schematic view of a protective device for steel structure roof installation according to an embodiment of the present invention; FIG. 2 is another schematic view of a protective device for steel structure roof installation according to an embodiment of the present invention; FIG. 3 is a schematic structural view of a protective device for steel structure roofing installation according to an embodiment of the present invention; FIG. 4 is a schematic diagram of a leader hook of a protective device for steel structural roofing installation according to an embodiment of the present invention; fig. 5 is a view illustrating a scene of a rope guide hook of a protection device for steel structure roof installation according to an embodiment of the present invention.
As shown in fig. 1 to 3, a protection device for steel structure roof installation is used for providing protection for steel structure roof structure construction, and includes a protective net guide rope 6 arranged below a roof structure 1, a sliding ring 7 sleeved on the protective net guide rope 6, and a protective net 2 connected with the protective net guide rope 6 through the sliding ring 7; the protective net guide rope 6 is longitudinally arranged along the roof structure 1, and two ends of the protective net guide rope are respectively fixed on a steel column 31 at the starting end and a steel column 32 at the stopping end of the steel structure.
It should be noted that the steel structure includes steel columns fixed on the floor of the factory building according to the design drawing, and a roof structure installed on the top of the steel columns. Because whole roofing structure area is great, if assemble the whole back together of whole roofing structure, hoist and mount again, inconvenient construction. Therefore, the roof structure needs to be divided into at least two roof structure units, the roof structure units are assembled one by one, and then the roof structure units are hoisted one by one and installed. Two protective net guide ropes 6 respectively penetrate through sliding rings 7 connected with the left side and the right side of the protective net 2, then the two protective net guide ropes 6 are erected on the inner sides of the steel column upper columns, and the protective net is stretched. The size of the protective net is equivalent to the projection of each roof structure unit, and the protective net can slide back and forth on the guide rope to a required position through tensioning.
In a specific implementation process, 2 protective net guide ropes 6 are erected on the inner sides of the steel columns 3 below the roof structure 1, and two ends of each protective net guide rope 6 are fixed to a starting end steel column 31 and a stopping end steel column 32 respectively. In order to further improve the protection effect, the arrangement position of the guide rope 6 of the protective net is the position of the upper column of the steel column. If the height of the guide rope of the protective net is too low, the fall between the protective net and the construction position of the roof structure is large, and the risk that constructors are injured still exists in the protection process.
Specifically, the middle of the guide rope 6 of the protective net is divided into at least two protective units by the separator 4, and the protective units correspond to the roof structural units; the separating piece 4 is used for limiting the protective net 2 to slide out of the protective unit, and the separating piece 4 is detachably connected with the protective net guide rope 6. That is, the guide rope of the protection net is divided into at least two protection units by adopting the separating piece arranged on the guide rope of the protection net, so that the protection net slides in the protection units; the separator is detachably connected with the guide rope of the protective net; when the protection network needs to be moved to the next protection unit, the separation piece and the protection guide rope only need to be detached to realize the protection device. The protection unit does not need to be frequently built and disassembled, so that the problem that the protection unit occupies a large amount of manpower and material resources due to frequent disassembly in the steel structure construction process is solved; the technical effects of reducing material loss and improving the construction efficiency of the steel structure are achieved.

That is to say, the link is the stiff end, and bears the weight of the end and be the free end that the link extends outward, bears the weight of the end inflexion and forms U type inner chamber, bears the top opening of end for protection network guide rope 6 can deviate from or overlap into from the opening. In the specific implementation process, a rope guide supporting hook is welded on the inner side of the upper steel column, the rope guide supporting hook is a U-shaped device with an opening at the upper end, and the rope guide supporting hook can be made by cutting a steel plate. The partition piece is arranged to be the guide rope unhooking, so that on one hand, the guide rope of the protective net can be borne, supporting points are added for the guide rope of the protective net, the bearing capacity of the protective net is improved, and the safety of the protective net can be improved; on the other hand, when the protection guide rope is in the bearing end of the guide rope unhooking, the sliding ring is unhooked by the guide rope to prevent the sliding ring from continuously sliding, so that the partition 4 is used for limiting the protective net 2 to slide out of the protective unit, and the protective net only slides in the protective unit. Thereby increasing the safety of the protective net. In order to further increase the safety of the protective net, the protective net is formed by twisting steel wires and nylon.
As shown in fig. 5, as an improvement of this embodiment, in order to further improve the limiting effect of the rope guide hooks on the sliding ring 7, two rope guide hooks are arranged on one steel column 3, and a limiting area for limiting the displacement of the sliding ring 7 at the four corners of the protection net 2 is formed between the two rope guide hooks. That is to say, the protective net guide rope 6 is a steel wire rope wrapped with plastic skin, two ends of the protective net guide rope are respectively fixed with the steel column 3, and the middle of the protective net guide rope 6 is hung on the guide rope support hook. The rope guide supports are hooked on each steel column in pairs, the sliding rings 7 are located between the two rope guide supports, the sliding ring devices at the four corners of the protective net are prevented from sliding in the using process, and therefore the stability and the safety of the protective net are further improved. In order to further prolong the service life of the guide rope 6 of the protective net, a wear-resistant rubber sleeve for reducing the guide rope 6 of the protective net is arranged in the bearing end of the guide rope supporting hook.
In order to further improve the convenience of operation, a hauling rope for tensioning the protective net is arranged at the front end of the protective net. The movement of the protective net can be completed by stretching the traction rope on the ground, so that the overhead working time of constructors is reduced. Specifically, one pulling rope needs to be provided at each of two corners of the front end of the protection net (i.e., the end near the moving direction of the protection net).
Specifically, after the roof structure construction of a unit is finished, the guide ropes of the protective net at the guide rope support hooks in the moving direction of the protective net are lifted and separated from the guide rope support hooks, a constructor stands on a crane beam to pull the traction ropes at two ends of the protective net to slide the protective net to the lower side of the next roof unit, when the sliding ring devices at four corners of the protective net are located between the two guide rope support hooks, the guide ropes are hung on the guide rope support hooks, and at the moment, the sliding rings are just blocked between the two guide rope support hook plates to prevent sliding.
The invention also discloses a protection method for steel structure roof installation, which comprises the steps of S110-S160.
