Abstract
The utility model discloses a light support frame for staircase steps, which comprises a sheet-like main body provided with a circular central location hole and a plurality of circular reinforcing holes which are distributed outside the outer circle of the central location hole. Peripheral reinforcing ribs formed by being stretched and flanged towards the same side are arranged on the periphery of the outer circle of the reinforcing holes. The circular central location holes are arranged on the sheet-like main body and a plurality of circular reinforcing holes are positioned on the periphery of the circle around the circular central location holes so that the supporting frame becomes lighter; The reinforcing ribs formed by being stretched and flanged are arranged on the periphery of the outer circle of the reinforcing holes so that the loading capability of support frames of the same thickness, thereby efficiently improving loading strength along with reduction of weight of the support frame, reducing cost and reducing energy consumption generated in operation of staircases.
Description
Technical field
The utility model belongs to staircase and makes the field, especially relates to a kind of light-duty stair footplate bracing frame.
Background technology
The stair step bracing frame is one of basic building block of assembly type step, is to be formed by metallic plate punching, and support body is roughly triangular in shape, and the middle part has leg-of-mutton hollow bulb.Modular stair step generally includes two and vertically installs, the bracing frame that is parallel to each other, and the top of bracing frame is connected with the pedal assembly of trampling for the passenger; The rear end is connected with the kickplate assembly of step; Front end is connected with in order to strengthen the loading strength of stair step, particularly bears the effect from the power of vertical directions such as pedal assembly, and the front cross rail that is subjected to displacement of the bracing frame that is parallel to each other of restriction and the main wheel axle bed that is used to form loop pulling ladder road; The lower end of bracing frame is connected with the jockey pulley of supporting step to move by the jockey pulley seat.Step is when operation, and two bracing frames vertical, the installation that is parallel to each other must bear from passenger's the gravity and the tractive force of main wheel axle bed.Therefore, triangle support frame is the core supporting member of stair step.For the loading strength that guarantees staircase when operation meets the safe operation standard and the step integral structure is stable; the bending distortion prevents to twist under the effect of triangle support frame because of the tractive force of undercapacity in the vertical direction and front end; cause whole terraced road et out of order; bring potential safety hazard to the passenger; even crisis passenger's life security, the support body of triangle support frame must be selected thicker sheet metal for use.And adopt thick and heavy sheet metal, intensity that assurance has been arranged, but the cost of producing and moving can be than higher.
The utility model content
The purpose of this utility model is to provide a kind of intensity height, lightweight light-duty stair footplate bracing frame.
For achieving the above object, the technical solution adopted in the utility model is: the light-duty stair footplate bracing frame, comprise a sheet main body, and have a circular central knock hole and some circular reinforced holes on the described flake main body; This circle reinforced hole places the circular central knock hole excircle outside, dispersed arrangement; Be provided with towards the same side stretch flanging formation periphery reinforced rib at the reinforced hole circumferential periphery.
This programme is by having the circular central knock hole on flake main body, the periphery that centers on the circular central knock hole has been provided with some circular reinforced holes, has alleviated the weight of bracing frame; The reinforced rib that stretch flanging forms is set on the circumferential periphery of reinforced hole, increased load-carrying capacity with the thick bracing frame of sample, when reducing the bracing frame own wt, effectively raise loading strength, saved cost, reduced the energy consumption of staircase at operational process.
As improvement of the present utility model, also have some Long Circle reinforced holes on the described flake main body, on the circumferencial direction that is arranged on the circular central knock hole excircle outside that this Long Circle reinforced hole and circular reinforced hole are staggered, be provided with towards the same side stretch flanging formation periphery reinforced rib at Long Circle reinforced hole circumferential periphery.
As further improvement of the utility model, described flake main body edge is provided with towards a layback stretches flange formation outer rim reinforced rib, this outer rim reinforced rib and described periphery reinforced rib homonymy.
Description of drawings
Fig. 1, the utility model light-duty stair footplate bracing frame integral structure scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
1. flake main body; 2. circular central knock hole; 3, circular reinforced hole; 4. Long Circle reinforced hole; 5. periphery reinforced rib; 6. outer rim reinforced rib.
As shown in Figure 1, light-duty stair footplate bracing frame of the present utility model, comprise a sheet main body 1, have a circular central knock hole 2 and some circular reinforced holes 3 on the flake main body 1, this circle reinforced hole 3 places the circular central knock hole 2 excircles outside, be dispersed arrangement, be provided with towards the same side stretching at circular reinforced hole 3 circumferential peripheries and turn over all over forming periphery reinforced rib 5.
In actual applications, in order to reach the effect that better alleviates deadweight and improve intensity, can between circular reinforced hole 3, set up some Long Circle reinforced holes 4, this Long Circle reinforced hole 4 interlocks with circular reinforced hole 3 on the circumferencial directions that are arranged in the circular central knock hole 2 excircles outside that disperse, be provided with towards the same side stretch flanging formation periphery reinforced rib 5 at Long Circle reinforced hole 4 circumferential peripheries, the periphery reinforced rib of the periphery reinforced rib of these Long Circle reinforced hole 4 circumferential peripheries and circular reinforced hole 3 circumferential peripheries is towards the same side.In the present embodiment, circular reinforced hole is 3, and the Long Circle reinforced hole is 2.Thick in order to reduce material, can stretch flange towards a layback at flake main body 1 edge and form the outer rim reinforced rib, this outer rim reinforced rib 6 and periphery reinforced rib 5 homonymies.
The utility model is by offering circular reinforced hole, Long Circle reinforced hole and center positioning hole on flake main body, outer circumferential edge stretch flanging at reinforced hole forms reinforced rib simultaneously, actv. has alleviated the deadweight of bracing frame, improve bracing frame and born positive pressure from the passenger, the twisting resistance that chain causes the traction of main wheel when moving from staircase, overall performance is good, and processing and fabricating is convenient; Behind reinforced rib outside the flake main body periphery is provided with, can select for use relatively thinner light weight section to make, save cost.The step total weight of realizing same specification reduces, and is beneficial to the cost of energy consumption, saving staircase manufacturing and operation when reducing the staircase operation.In addition, what open on the utility model main body all is Long Circle hole, circular port, does not need complicated punching drawing die, and mould is less, and the making die cost is low.
