Residential area inside ladder making method

Abstract

The invention discloses a residential area inside ladder making method. The residential area inside ladder making method comprises the following steps of S100, providing ladder rung plates and bending the ladder rung plates according to a set angle; S200, providing a ladder assembly and mounting the bent ladder rung plates on the ladder assembly at equal intervals in a length direction of the ladder assembly, wherein the adjacent ladder rung plates are not connected with each other and gaps are reserved between the adjacent ladder rung plates in a horizontal direction; and S300, plugging the gaps by using base plates. Compared with the prior art, the residential area inside ladder making method disclosed by the invention has the advantages of simple operation, high production efficiency and low reworking rate.

Description

technical field [0001] The invention relates to a method for making a ladder in a residential area. Background technique [0002] According to Regulation 13, Part D, Chapter II-2 of the International Convention for the Safety of Life at Sea (SOLAS), the accommodation area of ​​a ship is required to be designed with two escape routes away from each other. As one of the main escape routes, indoor inclined ladders in residential areas are frequently used. The quality of the design and structure of the inner ladder will directly affect the production and use of the inner ladder. Existing inner ladder step making method is as follows Figures 1 to 3 As shown: First, bend the ladder tread 1' of the same width at a certain angle; secondly, weld the bent ladder tread 1' to the ladder frame 2', and fillet welding is used between the ladder treads 1' OK; then lay 10mm thick deck covering 3' and 2mm thick plastic floor 4' on the ladder tread 1'; finally install the anti-slip strip 6'...

AI Technical Summary

Problems solved by technology

First of all, in the production process, if the blanking width, bending position and angle of each ladder tread 1' are different, the corner joints between the ladder treads 1' will not be very good; secondly, the ladder treads 1' A slight deviation in the positioning of 'on the ladder frame 2' will also affect the implementation of the fillet welding between the ladder treads 1'; moreover, in order to ensure that welding can be performed, it is necessary to carry out welding on the ladder treads 1' with precision problems. Necessary modifications, which will not only affect the construction schedule, but will also increase labor costs and material costs

[0005] (2), single construction sequence

During production, in order to reduce errors as much as possible, workers can only install the ladder step plate 1' step by step from the upper end of the ladder frame 2', and the labor efficiency is low

[0006] (3), it is easy to cause damage to the deck covering 3' and the plastic floor 4'

First of all, when the anti-slip strip 6' is installed, the screw 5' is directly tapped on the ladder tread plate 1', which is easy to destroy the deck covering 3' and the plastic floor 4' between the anti-slip strip 6' and the ladder tread plate 1' Secondly, there is only one layer of soft deck covering 3' and plastic floor 4' between the two, and if you step on the anti-skid strip 6' for a long time, it will cause damage to this layer of material; moreover, the repairing in the later stage will affect the construction progress and will also Increase labor cost and material cost
