Abstract
Disclosed is a steel grating plate fixing structure. The steel grating plate fixing structure solves the technical problem that special equipment in a traditional welding or snapping fixing mode is heavy, inconvenient to mount and dismount, restricted in construction, low in construction speed, time-consuming, labor-consuming and the like and belongs to the technical field of constructional engineering installation. The steel grating plate fixing structure comprises steel grating plate flat steels and a cross rod and is characterized in that the middle of a fastening clamp is provided with a slot, both sides of the slot are connected with the upper ends of the neighboring steel grating plate flat steels; a through hole is formed inside the slot, an internal thread bolt is arranged inside the through hole; the lower end of an external thread screw is deeply arranged into a steel structure base material and fixedly connected with the steel structure base material, and the external thread screw and the internal thread bolt are fixedly connected in a fastened mode. The steel grating plate fixing structure has the advantages of being vibration-resistant, impact-load-resistant, high in mechanical strength, safe and firm in usage, convenient and flexible to mount and capable of meeting the mounting requirements of different types of steel grating plates.
Description
Technical field
The utility model belongs to construction engineering mounting technique field, be specifically related to be applied to the fastening of steel checkerboard in the steel structure construction projects such as oil refinery, chemical plant, power station, industrial premises, manufacturing mechanism and operating platform, relate in particular to a kind of fixed structure of steel checkerboard.
Background technique
Steel checkerboard is to carry out cross arrangement with band steel according to certain spacing and cross bar (twisting square steel, square steel, round steel, band steel etc.), and be welded into middle a kind of steel product with square grid, steel checkerboard is mainly used to do ditch cover plate, steel structure platform plate, the step plate of steel ladder etc. steel checkerboard generally adopts carbon steel to make, surface treatment mode has hot galvanizing, cold galvanizing, sprays paint etc., can play the effect of anti-oxidation.Also can adopt stainless steel to make.
Steel checkerboard platform and other materials comparison are the modes of bearing the material saving of same load; On-the-spot without reprocessing, install very fast; Durable in use, preservative treatment before dispatching from the factory, shock-resistant strong with weight ability; Beautiful shape, anti-contamination thing, reduces windage, designs the advantages such as easy, and the technical advantage that it is unique and long-term value are more and more adopted by the Steel Structure Work of derived energy chemical, industrial premises and power station.And steel grating structure is as the load-bearing structural member of process units operating platform and visual plant, installation requirement is high, and high-lift operation and cross-operation are installed and brought inconvenience for platform again.According to incompletely statistics, energy Petrochemical Projects is installed steel checkerboard platform that the probability of the casualty accidents such as workman falls occurs is higher.
Two kinds of conventional steel checkerboard means of fixation have two kinds at present: traditional welding and clamping Placement.These two kinds of means of fixation all have its defect and deficiency.
Traditional welding means of fixation is the Placement between most widely used steel in engineering.For main equipment, welding is a kind of means of fixation reliably, but in a large amount of and very scattered light-duty fixation application, as fixing in platform etc., welding manner just exposes shortcomings, is mainly manifested in: light-duty immovable point relatively disperses, and electric welding equipment is heavier, operator, for guaranteeing to arrive working surface, need continuous mobile welding machine and electric wire very inconvenient; And welding job is subject to the impact of external environment condition larger, need to be through personnel's operation of special training, speed of application is slow, time-consuming taking a lot of work.Snap fit is also a kind of comparatively economic Placement in Steel Structure Work, but can not resist impulsive load and shock loads because of it, under load action, can produce and become flexible, and has potential safety hazard; And snap fit can only be arranged on girder steel edge of a wing place, cannot be arranged on C shaped steel or steel pipe, there is construction narrow limitation; At steel checkerboard bottom fastening nut, installation is torn open all very inconvenient.
Summary of the invention
For the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of fixed structure of steel checkerboard flexibly safe and reliable, easy for installation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steel checkerboard fixed structure, comprise steel checkerboard band steel and with the cross-coupled cross bar of described band steel, and steel structure base material, is characterized in that: also comprise anchorage clip, internal thread bolt and screw with external thread; In the middle of described anchorage clip, be equipped with groove, the both sides of described groove join with adjacent steel checkerboard band steel upper-end surface respectively; The vertical through hole of the built-in and described groove of described groove, the built-in described internal thread bolt of described through hole; Described screw with external thread underpart is goed deep in steel structure base material, is fixedly connected with described steel structure base material; The internal thread that the outside thread that described screw with external thread top is equipped with and described internal thread bolt bottom are equipped with, screw threads for fastening is connected and fixed mutually.
The diameter of described through hole and the built-in described internal thread diameter of bolt match, and are less than the bolt head diameter of described internal thread bolt.
Described steel checkerboard anchorage clip groove both side ends, by horizontal downward bending, is interior clasp shape.
Compared with prior art, good effect of the present utility model is: 1. use safety firm: anti-vibration and impulsive load, and mechanical strength is high, and safety firmly, become flexible by long-term use;
2. easy for installation flexible: without special device and power supply, one man operation realizes large size quick mounting;
3. cost simple in structure is low: detachable and Reusability, meets dissimilar steel checkerboard installation requirement.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, 1-anchorage clip; 2-groove; 3-through hole; 4-internal thread bolt; 5-screw with external thread; 6-steel structure base material; 7-steel checkerboard band steel; 8-steel grating cross bar; 9-interior clasp.
Embodiment
Fig. 1 is structural representation of the present utility model.As shown in the figure, a kind of steel checkerboard fixed structure, comprise steel checkerboard band steel 7 and with the cross-coupled steel grating cross bar 8 of described steel checkerboard band steel 7, and steel structure base material (girder steel) 6, is characterized in that: also comprise anchorage clip 1, internal thread bolt 4 and screw with external thread 5; In the middle of described anchorage clip 1, be equipped with groove 2, the both sides of described groove 2 join with adjacent steel checkerboard band steel 7 upper-end surfaces respectively; Described groove 2 is built-in with the through hole 3 vertical with described groove 2, the built-in described internal thread bolt 4 of described through hole 3; Steel structure base material 6(girder steel is goed deep in described screw with external thread 5 underparts) in, be fixedly connected with described steel structure base material 6; The internal thread that the outside thread that described screw with external thread 5 tops are equipped with and described internal thread bolt 4 bottoms are equipped with, screw threads for fastening is connected and fixed mutually.
