Description

Technical Field

[0001] The invention relates to the technical field of indoor escalator decorative panels in buildings, in particular to an assembled escalator decorative panel connecting device. Background Art

[0002] Escalators are used as traffic bridges in public places such as shopping malls, supermarkets and office buildings. They are generally located at the junction of floors. They are suspended and in a dangerous position. Therefore, the decoration construction of escalators generally requires the erection of scaffolding, and the finishing materials are moved to the scaffolding before being installed by welding. This construction method has the following problems. First, the escalator is generally set at an inclination angle of 30° or 35°. After the scaffolding is erected, the working surface is narrow and the workers can only bend their bodies to work, which is inefficient. Second, the decorative materials temporarily stacked on the scaffolding aggravate the tension of the scaffolding working surface. Third, the welding process uses a variety of pollution types and great hazards during the welding process. At the same time, it is inconvenient to disassemble and maintain the finishing surface in the later stage. In view of this, designing an escalator finishing installation connection device with a sliding function to achieve green construction and assembly installation has become a technical problem to be solved.

[0008] During assembly, the connecting panel of the special groove-type keel is connected to the steel structure foundation at the bottom of the escalator through fasteners, the metal upper clip and the metal lower clip are respectively mounted on the T-shaped connector of the pulley connector through perforations, the U-shaped metal clip is fixed to the bottom of the T-shaped connector of the pulley connector, the pulley and the metal upper clip are inserted into the guide rail through the lateral opening of the special groove-type keel, after the pulley connector slides to the corresponding position, the metal upper clip and the metal lower clip are locked and fixed by tightening screws, the vertical end face of the L-shaped angle code extends into the U-shaped metal clip and is locked by lateral bolts to fix the decorative panel.

[0009] The decorative plate has a plurality of folding plates with connecting protrusions, and the horizontal end faces of the L-shaped corner codes are fixedly connected to the corresponding connecting protrusions on the decorative plate in the factory.

[0010] The special grooved keel has a plurality of intervals and is fixed side by side at corresponding positions of the steel structure foundation at the bottom of the escalator.

[0011] When the two decorative panels are spliced ​​left and right, the horizontal end face of the L-shaped angle code is fixedly connected to the corresponding raised side edge of one of the decorative panels, and the raised side edges of the two decorative panels are closely spliced ​​and fixed by rivets.

[0012] When two decorative panels are spliced ​​left and right, the corresponding raised side edges on each decorative panel are connected to the L-shaped corner brackets on the respective connecting devices, and the raised side edges of the two decorative panels are closely spliced ​​and fixed by rivets.

[0013] The pulleys arranged side by side on the left and right are four left-right symmetrical pulleys, and the four left-right symmetrical pulleys are respectively connected to the top of the T-shaped connecting piece.

[0014] The decorative plate is a stainless steel plate.

[0015] The steel structure foundation at the bottom of the escalator is a transverse steel keel and a lateral L-shaped channel steel, and the special groove keel is fixed to the transverse steel keel and the lateral L-shaped channel steel at the bottom of the escalator by automatic screws.

[0016] After adopting the above structure, the new type of sliding positioning cooperation of the special groove keel and the pulley connector makes the construction not restricted by the site. After the decorative panel is installed in a spacious position, it can be directly slid into the corresponding position and locked. The construction is convenient and suitable for construction in narrow positions such as escalators, with high construction efficiency. In addition, since the connection device of the new type adopts the assembly principle, all product accessories are prefabricated in the factory, and the on-site simple splicing and assembly installation are green and environmentally friendly. It can be seen that the new type is suitable for the construction of narrow positions of escalators, assembly construction, high construction efficiency, and green and environmentally friendly.
