Adhesive tape and cutting jig thereof

Technical Field

The utility model relates to an architectural decoration field, concretely relates to adhesive tape and cutting jig thereof.

Background

The integral bathroom is a commodity which is produced in an industrialized way integrally in the bathroom, is matched and integrated and is quickly installed on a construction site, an integral space is formed by combining an integrated waterproof disc or a waterproof disc with a wall plate and a top plate, and an independent sanitary unit formed by matching various functional sanitary wares realizes multiple functions of washing, bathing, dressing, toileting and the like in a limited space, and the aspects of water prevention, water supply, drainage, light environment, ventilation, safety, storage, thermal environment and the like are considered comprehensively, so that the integral bathroom has the characteristics of reliable quality, water resistance, impermeability, convenience in installation, variable style and the like; at present, the integral bathroom has the remarkable advantages of waterproof performance, dry construction, quick connection installation and the like, and is favored by operators, local producers, builders and other multi-aspect customers such as chain hotels, long-rented apartments and the like.

The horizontal connection of the traditional SMC wallboard adopts a self-tapping self-drilling screw and gasket mode for connection and fixation, and the gap of the plates is sealed by a glass cement mode;

above-mentioned mode is because two wallboards can't realize the location before the horizontal concatenation, and self tapping self-drilling screw can have the error when directly punching at the scene, therefore this kind of connected mode has following defect: (1) after the two wallboards are spliced, dislocation exists, and the joint is uneven; (2) the sealing performance of the joint is poor; (3) the glass cement is exposed to cause the glass cement to easily fall off and affect the appearance, if the cement is not well glued, the problems of screw corrosion, mildew and falling off, integral deformation and cracking of the decorative plate and the like can be caused after the glass cement is used for a period of time, the difficulty in repairing is high, the integral replacement cost is high, the integral bathroom product is not seen by customers, the complaint rate of the product is high, the cost is lost and the pressure is accumulated, a large amount of manpower, financial resources and social resources are wasted, and the problem that the integral bathroom is troubled remains to be solved in the wilderness.

In order to solve the above problems caused by the above screw butt joint method, some companies in the current market adopt a mode of matching adhesive tapes and fasteners to realize assembly and sealing, for example, CN206319533U discloses a galvanized iron M-shaped wallboard horizontal joint connecting piece, the whole section of which is an M-shaped connecting piece, two ends of a low cross section are connected with vertical faces provided with return hooks, a mounting port is arranged between the two return hooks, and an inner corner groove is arranged between the vertical face and the return hooks.

However, the horizontal seam connector of the M-shaped wallboard still has the following defects when actually matched with the adhesive tape: (1) after assembly, the problems of uneven gaps, obvious steps, poor sealing performance and the like still exist; (2) after the SMC wallboard is produced in a factory, secondary processing needs to be carried out on the rib position behind the wallboard, so that the strength of the wallboard is influenced, and the problems of complex processing technology, high cost and the like exist.

Therefore, in view of the above technical defects, the problems of uneven joints and poor sealing performance when connecting SMC wallboards horizontally still need to be further improved.
