Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.

As shown in fig. 1-3, the embodiment of the present invention provides a method for installing a cylindrical stainless steel handrail, where the cylindrical stainless steel handrail includes a stainless steel handrail 1, a stainless steel handrail 2, tread plates 3, and a ladder beam 4, the stainless steel handrail 1 is a long rod welded to multiple sets of stainless steel handrails 2, the bottom of the stainless steel handrail 2 is connected to multiple sets of tread plates 3, the ladder beam is installed on the side surface of each tread plate 3, and an installation platform 5 is installed on one side of the cylindrical stainless steel handrail.

Further, the bottom of the stainless steel rail 2 is provided with a horseshoe opening 6, the horseshoe opening 6 is inserted into the upper opening of the ladder beam 4, and the contact periphery of the horseshoe opening 6 and the ladder beam 4 is welded.

Further, the step plate 3 is divided into an upper layer and a lower layer, the distance between the step plates 3 on the upper layer and the lower layer is 200mm, the width of each layer of the step plate 3 is 230mm, the length of each layer of the step plate 3 is 1000mm, and the surface of the step plate 3 is galvanized.

Further, the mounting platform 5 is surface galvanized.

Further, the specific installation steps are as follows:

a. loading and unloading vehicles and stacking components on site, and performing mildew-proof, pollution-proof and corrosion-proof treatment on finished products;

b. the assembly and the hoisting of the stairs are realized by firstly carrying out paying-off measurement on the steel ladder and rechecking the sizes of the site and the processed components. After rechecking, the stainless steel ladder beam with the plate thickness of 8mm and the plate width of 180mm is firmly assembled with the galvanized step plates on the ground, the distance between the upper step plate and the lower step plate is 200mm, the width of each step plate is 230mm, and the length of each step plate is 1000mm, so that the steps are integrated. According to the shape, section, length and weight of the steel ladder, a mechanical steam hoist or an electric hoist can be selected. Before hoisting, the steel ladder to be installed is placed close to the installation position, and then the steam hoist is parallel to the middle of the steel ladder to support a bracket. After the steam crane is stably placed, a steel wire rope with the diameter of 15mm and a shackle with the load limit of 1.0 ton are used, one end of the steel wire rope is directly hung on a lifting hook of the steam crane, the lifting hook on the crane needs to be fixed by an anti-tripping buckle, the steel ladder is lifted after all preparations are finished, each part needs to be observed and checked when the steel ladder is 300mm away from the ground, no problem is confirmed to be caused to carry out vertical lifting, the steel ladder is balanced and stable during lifting, and tools such as crowbars and the like can be used for assisting in positioning after the steel ladder is lifted to an installation position. After the steel ladder is in place, correcting the steel ladder according to the angle of 45 degrees required by a design drawing, and then welding and fixing the steel ladder according to the standard requirement after correcting the elevation, the angle and the axis without errors;

c. installation of stainless steel railing, cylinder stainless steel railing and stainless steel ladder roof beam lug connection, the degree of difficulty lies in the contact surface undersize of cylinder, leads to with ladder roof beam welding insecure and pleasing to the eye. The stainless steel railing is placed on a line before installation, so that the accurate position of the stainless steel railing can be determined. Then one end of the cylindrical stainless steel railing is uniformly cut into a horseshoe mouth with the height of 50mm-100mm and the width of 10mm from the middle by a hand-held cutting machine, the horseshoe mouth is inserted into the upper opening of the stainless steel ladder beam according to the previously determined position, two persons are matched at this time, one person holds the stainless steel railing to keep the stainless steel railing vertical, the stainless steel railing cannot shake during welding, the other person carries out spot welding positioning, the whole number of the stainless steel railing is rechecked for verticality and the like after all the stainless steel railings are positioned, the periphery of the horseshoe mouth is fully welded in a subsection mode after the situation that no problem exists is determined, a welding seam is required to meet design requirements and construction specification, and the stability of the stainless steel railing;

d. the stainless steel handrail is installed, and the stainless steel handrail upper shed is through lengthening the unwrapping wire, then welds the installation in order from one end to the other end with stainless steel handrail pipe, and adjacent handrail installation butt joint is accurate, and the seam is tight. After the adjacent stainless steel handrail round tubes are butted, the joint is subjected to argon arc spot welding. Before welding, the position interval, the straightness and the radian of a corner elbow must be checked, oil stain, burrs, rusty spots and the like within the range of 30-50 mm along each side of a welding line are cleaned, if necessary, an angle grinder can be used for grinding, two sides of the metal surface are fully welded at the same time, the welding line is not too long once, and the stainless steel is prevented from being subjected to thermal deformation;

e. and (4) polishing, after all welding is finished, flattening and sanding the welding line by using a portable grinding wheel polisher until the welding line is not shown, polishing by using a flannelette grinding wheel or felt during polishing, and simultaneously using corresponding polishing paste until the welding line is basically consistent with the adjacent base material and is not shown.

In conclusion, the installation method is simple and easy to implement and low in manufacturing cost; the problem of at cylindrical stainless steel railing and the unable reliable installation of stainless steel stair ladder beam welding is solved, reduction in production cost is easy to assemble.

It should be noted that various standard components used in the present invention are commercially available, non-standard components are specially customized, and the connection manner adopted in the present invention, such as bolting, welding, etc., is also a very common means in the mechanical field, and the inventor does not need to describe herein any further.

The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
