Method for cleaning bottom of manual plate steel door

Abstract

The invention discloses a method for cleaning the bottom of a manual plate steel door. The method comprises the following steps that S1, a bearing strip is fixed to the bottom of a door plate; S2, a lower horizontal plate B of a middle strip with an I-shaped cross section is inserted into a sliding groove in a bearing piece, the bearing piece is an elastic rubber strip, and the bottom of the bearing piece is connected with bristles; S3, the top of the upper horizontal plate B of the middle strip is connected with the bottom of the bearing strip through a spring; and S4, stop pins are installedat two ends of the bearing strip, buckling pieces are connected to two ends of the middle strip through hinges, the ends, away from the hinges connected with the buckling pieces, of the buckling pieces are rotated, the stop pins located above the buckling pieces are sleeved with stop pin holes in the buckling pieces, the spring is in a compressed state, and the upper side hole walls of the stop pin holes are attached to the upper side walls of the stop pins. The bristles are arranged at the bottom of the door plate and make contact with the ground every time the door is opened and closed, sothat the ground at the bottom of the door plate is swept, dirt is prevented from accumulating at the entrance and exit, subsequent ground cleaning is facilitated, and the cleaning difficulty is reduced.

Description

technical field

[0001] The invention relates to the field of conforming steel plates, in particular to a method for cleaning the bottom of a manually plated steel door. Background technique

[0002] Composite steel plate, also known as color steel composite plate, is a thermal insulation composite maintenance plate formed by compounding color-coated steel plate or other panels and bottom plates with thermal insulation core materials through adhesives or foaming. Composite color steel plate has the following advantages:

[0003] 1. Light weight, the weight of the composite color steel plate is 10kg-14kg / square meter, which is equivalent to 1 / 30 of the weight of the brick wall;

[0004] 2. It has good heat insulation, sound absorption and sealing performance;

[0005] 3. The construction is convenient, the installation is flexible and fast, and the construction period can be shortened by more than 40%;

[0006] 4. It has bright color and beautiful appearance, no need for su...
