Description
Technical field
The present invention relates to steel structural roof construction safety technical fields, and in particular to a kind of rack roofing is filled with construction protection
It sets.
Background technique
With the development of large-span space structure, grid structure is widely applied, as airport building, charge station,
, there is the application example of grid structure in the building such as workshop.Grid structure reasonable stress, rigidity are strong, light-weight, can be abundant
The tensile and compressive property of material is played, reduces moment of flexure and shearing to the adverse effect of material, and moulding is changeable, and can use according to building
It is required that adjustment size of mesh opening, to meet different use needs.The selection of current this structure is mainly steel, steel structure net rack
Application it is the most universal.
In steel structure net rack construction of hydropower, fireproof coating construction is carried out to rack roofing structure and is very important together
Process.Since roofing is in high-altitude, and roofing region is wide, has the rod member for grid that much intersects, construction personnel it is high in the air into
Inconvenient walking when row fireproof coating is constructed, and often carry out bending over to construct, it not can guarantee construction personnel in moving process
Safety.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rack roofings to be existed with construction protection device for construction personnel
Support is helped when high-altitude is mobile, while being also used for the hook of construction personnel's safety belt, is being moved through to effectively increase construction personnel
Safety in journey, while it is more convenient also to make to construct, and is conducive to site operation.
In order to solve the above technical problem, the present invention provides technical solution it is as follows：
A kind of rack roofing construction protection device, the rack are mainly formed by connecting by multiple rod pieces, the protective device
Including shaft, the shaft both ends are bent with hook respectively, and the bending angle of the hook is greater than 90 ° and is less than or equal to
180 °, the hook is in the same plane with the shaft, and the hook includes arc section and extended segment, the arc section
Radius of curvature is greater than or equal to the radius of the rod piece.
Plane where taking the shaft axis perpendicular with plane where hook is reference planes, the arc section and described is prolonged
Stretch the diameter that projection total length of the section in the reference planes is greater than the rod piece.
The hook at the shaft both ends is arranged symmetrically.
The extended segment and the shaft are at an acute angle.
The shaft uses screw-thread steel.
The diameter of the screw-thread steel is 14mm.
Rubber layer is connected on the outer wall of the crotch.
Non-slip texture is provided in the rubber layer.
The invention has the advantages that：Protective device of the invention can be hooked on net in the work progress of high-altitude
Easy to operate on the rod piece of frame, conveniently moving, for construction personnel, when high-altitude is mobile, support is helped, while being also used for construction personnel
The hook of safety belt, so that safety of the construction personnel in moving process is effectively increased, while it is more convenient also to make to construct,
Conducive to site operation, construction efficiency is improved.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
The rack of rack roofing is mainly formed by connecting by multiple rod pieces, and as Figure 1-Figure 2, the rack roofing is anti-with construction
Protection unit 5 includes shaft 51, and 51 both ends of shaft are bent with hook 52 respectively, link up with 52 bending angle be greater than 90 ° and be less than or
Equal to 180 °, hook 52 is in the same plane with shaft 51, that is, links up with 52 plane of symmetry and the axis place of a shaft 51
Plane coincides, and the hook 52 at 51 both ends of shaft is hooked on respectively on a rod piece when use, and hook 52 includes 521 He of arc section
Extended segment 522, the radius of curvature of arc section 521 are greater than or equal to the radius of rod piece.
Further, as shown in Fig. 2, by plane definition where the axis of the shaft 51 perpendicular with 52 place planes of hook
For reference planes, the projection total length of arc section 521 and extended segment 522 on the reference plane is L, and the rod piece that L is greater than rack is straight
Diameter, it is possible to understand that ground, 52 place planes of hook are the plane of symmetry for linking up with 52.The rod piece diameter that L is greater than rack can increase extension
The hook reliability of hook 52 is hooked on hook 52 more steadily on the rod piece of rack.
Further, the hook 52 at 51 both ends of shaft is arranged symmetrically, convenient for hooking, but also protective device 5 when hooking
Entirety be more uniformly stressed.
Further, linking up with 52 extended segment 522 and the angle of shaft 51 is α, and α is acute angle, can in order to link up with 52
Successfully hook the rod piece of rack.
Further, shaft 51 uses screw-thread steel, and load bearing effect is good, and plays the role of anti-skidding, can preferably hook
The rod piece of rack prevents hook 52 from slipping.
Wherein, the diameter of screw-thread steel is 14mm, light weight but has enough rigidity, can play preferable load-bearing effect
The diameter of fruit, screw-thread steel should not be too large, and to mitigate 5 overall weight of protective device, be mounted on rack to reduce protective device 5
Afterwards to the influence of rack stress, the diameter of screw-thread steel is also unsuitable too small, larger to avoid flexibility, influences stress.
Further, it links up with and is connected with rubber layer on 52 outer wall, when being contacted to avoid hook 52 with the rod piece of rack pair
The abrasion of rod member for grid.
Further, it is provided with non-slip texture in rubber layer, to increase the frictional force of hook 52 with rod member for grid, increases and hang
The hook stability and reliability of hook 52.
As shown in figure 3, the rack of rack roofing is mainly formed by connecting by multiple rod pieces by multiple bolt spheres 2, wherein net
The rod piece of the upper and lower periphery of frame is known as chord member, and the rod piece positioned at top is known as top boom 1, is known as lower boom positioned at following rod piece
4, the rod piece between the top boom 1 and lower boom 4 of rack is known as web member 3.Protective device 5 of the invention when in use, by shaft
The hook 52 of 51 one end is hooked on a web member 3, then the hook 52 of 51 other end of shaft is hooked on another web member 3,
By the web member 3 that the hook 52 at 51 both ends of shaft is hooked be at an angle, hook 52 can be fixed on two web members 3 it
Between, construction personnel it is high fireproof coating brushing is carried out to rack roofing structure in the air when can be with bearing rod body 51, and can be by safety
Band is hung on shaft 51, the safety of construction personnel and the convenience of construction is effectively ensured, and support is helped when construction personnel's movement
Shaft 51 further ensures safety of the construction personnel when moving on lower boom 4.
Protective device provided by the invention, structure are simple and convenient to operate, and materials are few, light weight, and reliability is good, especially suitable
The removable protection of personnel in high-altitude fireproof coating brushing construction is carried out on big area roof, protection effect is good, and safety is
Number is high, is conducive to site operation.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
