Stair slab and processing mould for same

Abstract

The invention discloses a stair slab and a processing mould for the same. The stair slab comprises a base plate and a cover paper layer fixedly pressed onto the base plate. The base plate is integral, the front and the rear of the base plate are parallel to each other, all sections in left vertical direction and the right vertical direction of the base plate are the same in shape, the base plate comprises a head, a body and a tenon portion sequentially from left to right, and the left of the head is a round head. The whole cover paper layer is continuously distributed on the upper outer peripheral side of corner sinks of the body, an upper plane of the body and the outer peripheral side of the round head of the base plate, and the outer peripheral side of the head includes an upper plane of a connecting portion, the outer peripheral side of the round head and a lower plane of the connecting portion, wherein the upper plane, the outer peripheral side of the round head and the lower plane are connected sequentially. The processing mould can be used for hot pressing of the cover paper on the head of the base plate, the upper surface of the body and the outer sides of the corner sinks during pressing once for an elongated stair slab, production efficiency is improved greatly, and the cover paper pressed onto the elongated stair slab is flat, continuous and attractive in appearance.

Description

technical field [0001] The invention relates to a stair bar and a processing mold thereof. Background technique [0002] Chinese patent document CN101804648 A (Application No. 201010134936.5) discloses a method for manufacturing a composite panel with a side round head wrapping angle, a processing mold and the composite panel, and mentions stair treads and its manufacturing mold and method. The stair treads include a round head on the right side and a board body with a rectangular cross-section on the left side. The central angle of the round head is at most 175 degrees. The lower left part of the round head also includes a cutting formed Rectangular gap, the lower end surface of the left part of the round head and the lower end surface of the right part of the plate main body are located in the same plane; the right side of the upper end surface of the plate main body is tangent to the upper left side of the arc cylinder of the round head, The lower part of the round head ...

AI Technical Summary

Problems solved by technology

[0007] Although the stair slabs prepared above solve the problems of raw material loss and the strength of the stair slabs, the types of flame-retardant boards used are relatively single. Nowadays, home decoration often requires the stair boards to be consistent with the style of the entire room. Stair boards made of flame-retardant boards There are very large limitations in appearance; in addition, when pressing the flame-retardant board, it is first pressed on the upper surface for 24 hours, and then the flame-retardant board is bent for 12 hours with a bending machine to fit the arc-shaped side of the first preparation board. If it is necessary to press the flame-retardant board on the arc-shaped side and the lower surface of the extension, the whole pressing process is complicated and takes a very long time

[0008] In addition, since the upper and lower corners of the other end of the above-mentioned stair treads or stair boards corresponding to the round head are at right angles, they cannot be assembled with the floor, and the width of the stair treads or stair boards must be the same as the width of the plane to be covered. The range is very limited
