Referring to fig. 1 to 4, a preferred embodiment of the present application provides a detachable bolt-exchanging protection platform 100 for steel truss chord splicing bolt-exchanging operation. As shown, the platform 100 includes a bracket assembly 1, a beam 2, a walking platform assembly 3, and a shield assembly 4. Wherein, bracket component 1 has two sets ofly, and two sets of bracket component 1 sets up relatively, and crossbeam 2 and protective component 4 connect into a whole with two sets of bracket components 1, have guaranteed this platform 100's stability.
Each set of support assembly 1 comprises two opposing ladder stands 11, each ladder stand 11 comprising a pair of vertical bars 111 and a plurality of cross bars 112 connected between the two vertical bars 111. In the present embodiment, the vertical bars 111 and the horizontal bars 112 are welded by equal angle steel with a side length of 40mm and a thickness of 3 mm.
Optionally, the bracket assembly 1 further comprises a fixing member 12 for fixing the cross beam 2 and the ladder 11, wherein the fixing member 12 improves the stability of the ladder 11 and thus the stability of the whole platform 100. Specifically, one end of the fixing member 12 is connected to the ladder 11, and the other end is connected to the cross member 2. In this embodiment, the fixing member 12 is made of angle steel, and the angle steel is welded to the ladder stand 11 and the cross beam 2, respectively.
The beam 2 is used for connecting the two groups of bracket assemblies 1. During actual construction, the two cross beams 2 are arranged oppositely and in parallel, and the two cross beams 2 are respectively connected to two sides of the two groups of bracket assemblies 1. Optionally, the cross beam 2 is a carrying pole beam. The stress characteristic of the shoulder pole beam is similar to that of the shoulder pole, the shoulder pole beam can adapt to a steel truss beam with higher height, and the construction safety and convenience are improved.
The walking platform assembly 3 is overlapped on two oppositely arranged crawling ladders 11 and is used for enabling a worker to walk on the crawling ladders. The walking platform assembly 3 includes an outer frame 31 and a base plate 32 mounted within the outer frame 31. Further, the outer frame 31 is a rectangular outer frame formed by splicing a plurality of square steel pipes. Illustratively, the cross section of the square steel pipe is rectangular, and the rectangular cross section has a length of 40mm, a width of 30mm, and a thickness of 3 mm.
In order to increase the friction force on the surface of the bottom plate 32 and prevent the worker from slipping due to too small friction force on the surface of the bottom plate 32 when walking, thereby affecting the personal safety of the worker, in one embodiment, the bottom plate 32 is a checkered plate with a thickness of 3 mm. Since the surface of the checkered plate has the pattern, the friction force of the surface can be improved.
Since the length of the walking platform assembly 3 is relatively long, and further the length of the outer frame 31 is also relatively long, in order to splice the complete walking platform assembly 3, in one embodiment, the bottom plate 32 has a plurality of pieces, and the plurality of pieces of the bottom plate 32 are sequentially welded in the outer frame 31.
It should be noted that, the walking platform assembly 3 can be overlapped at any height of the ladder stand 11, that is, the height of the walking platform assembly 3 can be set at any height according to the actual construction requirement, so that the high-altitude operation of the worker is more convenient.
The existing steel truss girder bolt changing platform is usually integrally connected and not detachable, so that the transportation and the detachment processes are very troublesome. To solve this problem, in the present embodiment, the guard rail 41 is detachably connected to the ladder stand 11. In one example, a slot pin 43 is mounted on the ladder 11, and a jack (not shown) is provided at the end of the guard rail 42, and the slot pin 43 is detachably connected with the jack. Further, notch bolt 43 is made by the steel sheet to the welding is in cat ladder 11 sides, and protection railing 41 is made by square steel pipe, and the side of square steel pipe is the rectangle, and the length of rectangle is 40mm, the width is 30mm, thickness is 3mm, and the bore size of notch bolt 43 and protection railing 41's pipe diameter phase-match have guaranteed that protection railing 41's one end can stretch into to notch bolt 43's notch in.
In another example, the guard rail 41 is threaded with the ladder 11 by bolts (not shown). Specifically, one side of the ladder 11 has a first threaded hole (not shown), one end of the guard rail 41 has a second threaded hole (not shown) matching the first threaded hole, the first threaded hole and the second threaded hole are connected by a bolt, and the guard rail 41 is further in threaded connection with the ladder 11.
Since the volume of the appliances or parts during actual construction is small, in order to ensure that the appliances or parts fall out of the meshes of the protection net 42, in one embodiment, the protection net 42 is a dense mesh protection net.
When the appliances or parts are accidentally dropped, the appliances or parts may fall onto the walking platform assembly 3 or fall between the walking platform assembly 3 and the gap of the protection net 42 due to the obstruction of the protection net 42. At this time, the workers need to squat down to pick up the appliances or parts, which is dangerous and time-consuming, and some appliances or parts cannot be directly picked up due to gaps, so that the construction difficulty is increased.
In order to facilitate the constructor to pick up the fallen instruments or parts and continue working, in one embodiment, a groove assembly (not shown) is further arranged between the walking platform assembly 3 and the protective net. The groove component comprises a movable groove and a movable handle connected with the movable groove, the movable groove is used for containing a falling appliance, and the movable handle is used for driving the movable groove to move up and down. For example, when the utensil falls on walking platform subassembly 3, constructor only need kick these utensils next door for these utensils fall into and remove the recess, mention the removal handle again, will remove the utensil in the recess or the part pick up can, whole process convenient and fast again safety.
In summary, the embodiment provides a detachable bolt-changing protection platform for a steel truss girder, which is reasonable in design and simple in structure, and comprises two groups of bracket assemblies, a beam, a walking platform assembly and a protection assembly, wherein each group of bracket assemblies comprises two crawling ladders which are arranged oppositely, the walking platform assembly is lapped on the two crawling ladders which are arranged oppositely, and the protection assembly comprises a protection railing and a protection net which is arranged on the protection railing; the problems that a conventional high-altitude construction operation platform is complex in supporting structure, complex to install, not detachable and not suitable for splicing and bolt replacing operation of steel truss chord members can be solved; in addition, the protective guard bar and the protective net are arranged on one side of the two crawling ladders, so that the parts such as workers, small appliances or bolts are prevented from falling off, and the construction safety is improved; in addition, the height of the walking platform assembly can be set at will by lapping the walking platform assembly at different heights of the ladder stand, so that the high-altitude operation of workers is facilitated.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
