High-altitude operation platform based on truss
This utility model relates to a kind of high-altitude operation platform, specifically a kind of high-altitude operation platform based on truss.
Steel building compares features such as having anti-seismic performance is good, construction speed fast, steel recoverable with traditional architecture, is widely used in the last few years. In steel construction, truss can form long-span space, and for producing or exhibition offer great convenience, therefore truss structure is widely used in the engineerings such as large-scale steel structure museum and building surface in big industrial factory. But typically requiring all kinds of pipelines of installation, insulation construction or roof inner slab etc. in truss, work high above the ground is dangerous big, and conventional construction method can adopt the method such as full hall scaffold or hoistable platform.
Full hall scaffold method, connection system for guide rail density is big, sets up workload very big, and efficiency is very low, and has much relations with floor construction progress, is not suitable between specialty work compound. Lift truck method is to utilize truck crane or wheeled lift truck etc. to construct, and the method requires that equipment investment is very big, and danger coefficient is very big, and job area is only limitted to a high-altitude part, has a strong impact on construction speed.
Summary of the invention
Goal of the invention: this utility model purpose is in that for the deficiencies in the prior art, it is provided that a kind of safely and efficiently for the operating platform of high-altitude truss construction operation. Can utilize steel plate that operation field is conventional, reinforcing bar, springboard etc. through simple assemble to be formed be prone to pacify the platform torn open, and can select to set up area as required, it is simple to efficiently construct.
Technical scheme: the high-altitude operation platform based on truss described in the utility model, truss including two intervals, on the web member of two truss, correspondence is provided with support hook respectively, and described in two, between support hook, parallel shelf is provided with many scaffolds, and described scaffold is equipped with springboard.
The concrete erection process of high-altitude operation platform of the present utility model is: on the web member of two truss, correspondence sets up support hook respectively, support hook relies on the restraining forces of self gravitation and two web members to be fixed on two web members, scaffold is set up again between the support hook of two truss, and on scaffold, lay springboard, complete the erection of whole operating platform.
This utility model further preferably technical scheme is, described support hook two ends are hook formation, and hook is located on adjacent two web members of described truss.
Preferably, described scaffold is fixed in described support hook by steel wire lashing, and described springboard is fixed on described scaffold by steel wire lashing.
Preferably, described scaffold is more than two, interval 0.8 ~ 1.2m between adjacent two scaffolds.
Preferably, described support hook at least 20cm is all stretched out at the two ends of every described scaffold.
Preferably, the bottom of two truss is also erected with bed board, and the two ends of described bed board are separately fixed on the lower boom of two truss, for providing the scope of operation installing operating platform. Bed board is first set up, it is possible to other components for setting up whole operating platform provide the scope of operation between two truss.
Preferably, the lower boom 8 ~ 20cm of described truss is stretched out at the two ends of described bed board.
Preferably, towing during for convenient erection and dismounting, one of them external part of described bed board is bent upwards the formation section of upwarping, it is possible to be pulled to truss lower boom by manually or electrically mechanism.
Beneficial effect: (1) high-altitude operation platform of the present utility model is set up based on truss, can utilize steel plate that operation field is conventional, reinforcing bar, springboard etc. through simple assemble to be formed be prone to pacify the platform torn open, large area work high above the ground face and putting up platform aspect are provided efficiently, mobile flexible; And putting up platform is independent of full hall scaffold and lift truck, do not limited by ground construction progress, technical measures can be saved and put into, improve efficiency of construction;
(2) in this utility model, described support hook at least 20cm is all stretched out at the two ends of scaffold, platform with the flowable use of extension of springboard, between adjacent two platforms can cooperating, working space is farthest provided.

Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment:A kind of high-altitude operation platform based on truss, including the truss at two intervals, bed board 1, support hook 2, scaffold 3 and springboard 4, as shown in Figure 1, 2:
The two ends of bed board 1 are separately fixed on the lower boom 5 of two truss, and the lower boom 8 ~ 20cm of truss is stretched out at the two ends of bed board 1, and one of them external part is bent upwards the formation section of upwarping.
Support hook 2 two ends are hook formation, hook is located on two web members 6 of truss respectively, parallel erection many between the support hook 2 of two truss (two or more than two) scaffold 3, interval 0.8 ~ 1.2m between adjacent two scaffolds 3, support hook 2 at least 20cm is all stretched out at the two ends of every scaffold 3, and scaffold 3 is laid springboard 4.
Process of specifically setting up is for a certain steel-structure factory building, and this factory roof truss is for tiltedly to put quadrangular pyramid row, the average discrepancy in elevation 3.5m of top-bottom chord, rod member length 4m, and lower edge spacing is 4m.
Bed board 1 length is 8.2m, and single weight is about 100kg, manually or electrically mechanism be pulled on truss lower boom 5 so that it is across two lower edge lattice, and reserve 10cm surplus at two ends; On the operating surface that bed board 1 provides, support hook 2 adopts the above simmering and bending reinforcing bar of Ф 20mm or other form bent member to ride upon on web member 6, relies on the effect of contraction of gravity and web member 6 to be fixed between rod member; The 1m colligation of scaffold 3 interval is in support hook 2, and length is 9m; Springboard 4 is laid on scaffold 3 and uses steel wire lashing.
Although as it has been described above, represented and described this utility model with reference to specific preferred embodiment, but it shall not be construed as the restriction to this utility model self. Under the spirit and scope premise of the present utility model defined without departing from claims, it can be made in the form and details various change.
