Soft Plywood Chair Indoor Mobile Grandstand Telescopic Bleacher Seating
Feature: Most of the telescopic tribune seating are placed in the conference hall, auditorium hall and stadium, gym, or some pubilc sport center. It can be closed and opened by electric control.
Performance introduction of the telescopic bleacher seating:
The telescopic bleacher seating has versatility and makes full use of the effective indoor area to meet the requirements of multiple seats under different use functions. Convenient operation and control, flexible function configuration. The telescopic bleacher seating is powered by a motor to ensure that the movable stand can be expanded and contracted easily and without deviation. The telescopic bleacher seating has excellent structural design, beautiful appearance, large load capacity, reliable safety measures, accurate positioning, easy operation, convenient maintenance, and low noise.
1. The design requirements of the telescopic bleacher seating
(1) In addition to the weight of the seat itself, the grandstand also satisfies the following load: dynamic load per square meter of 450kg; per meter length can withstand a swing load of 36kg.
(2) The guardrail design satisfies the horizontal force as follows: the guardrail can withstand 135kg per meter.
(3) Stand strength The stand structure strength is ≥200kg for each static load; the impact strength of the bed frame: each static load is ≥200kg. The middle load of each layer is ≥80kg, and the height of 300mm is not deformed. The overall structure is stable under dynamic load, and the bearing surface is not deformed.
(4) There are safe railings on both sides and the rear edge of the stand, and the surface is sprayed with plastic, so there is no need to plug and unplug during the expansion and contraction of the movable stand.
(5) The front of the stands is beautiful in appearance, and there are anti-skid strips on the stands to prevent the audience from slipping up and down.
System material description of telescopic bleacher seating
(1) Casters: use wide PU wheels. The inner layer adopts double ball bearings, the middle is a nylon layer, and then is covered with a high toughness and wear-resistant polyurethane layer, which can withstand huge forces without wearing the floor.
(2) Driving wheel: There are multiple reinforced PU structures, which provide the driving friction required for the stands, which can easily overcome ground defects, meet the needs of the stands, and do not wear the floor.
(3) Telescopic travelling wheel frame: The number of travelling wheel frame each row can be set according to the size and requirements of the venue. Each travelling wheel frame is equipped with more than 3 casters. When rolling on the floor, it will not damage the floor and leave no rolling traces.
(4) Structure: It adopts composite structure, and the material is alloy steel. There should be no welding in the middle of the rods of all load-bearing members. The thickness of the steel plate of the supporting member is ≥2.5mm, which is connected by high-strength positioning profiles. It can increase the strength and toughness of the material, improve the mechanical properties of the material, and enhance the stability of the structure. The load-bearing beam size is 50×40×2.5, and the column is 100×50×3. It is installed at a distance of about 70cm from the center and welded between the main beam and the auxiliary beam. The cold-rolled steel plate with sufficient bearing capacity is used, and after folding, it is sprayed to make it not only has good corrosion resistance, but also has a smooth and clean outer surface. The national standard high-strength bolts are used for on-site riveting (all screws and nuts are standard parts) to change the disadvantages of previous welding, so that it not only has good corrosion resistance and stability, but also has a smooth and clean outer surface. The auxiliary beam adopts 60×40×2 inner coiled profile, which is used as the structural element of all the wooden support arms and the walking surface. The supporting arm between the supporting frames is applied to the main beam to eliminate sliding friction and lubricate the roller and nails through the action of the mechanical surface.
(5) Movable step: The movable step keel is welded with high-quality carbon steel profiles to form a support, and the pedal is made of 17mm thick high-strength laminated composite solid wood board and 1mm thick melamine wear-resistant board. The surface layer is fixed by rivets and auxiliary stands of the stands to ensure the high strength and structural stability of the movable steps.
(6) Frontier: It adopts special aluminum-titanium alloy edging and special anti-skid lines to increase the strength of the bed frame and prevent the audience from slipping when walking. At the same time, anti-skid stripes are added to enhance friction and enhance safety factor.
(7) Synchronous telescopic device: adopts double-layer guide design, each driving device is connected by rigid shaft, and the stand support structure adopts mechanical feedback type synchronous telescopic device to ensure the synchronization of extension and retraction without directional deviation. The walking wheels of the stands are made of fixed-pull profiles and guided chutes are designed. Synchronous pulley guiding mechanisms are added to the upper layer of each group of stands every meter to ensure balanced linear movement during expansion and braking, and movement without noise.
(8) Telescopic bleacher seating seats: HDPE Chair or Foam Chair
(9) Stand aisle: Each floor is equipped with a box-shaped step (the craft is the same as that of the stand surface).
(10) Locking and handling system: The locking system uses equipment at the corner of the column and is designed to prevent the cart from moving.
(11) Plastic spraying: The steel components are all electrostatic sprayed on the automatic spraying line to enhance their corrosion resistance. The latter spraying procedure is to oxidize the powder coating by electrostatic spraying, at about 190 degrees for 20 minutes. The color is decided by the project manager.
Description of motor and power system:
(1) During operation, it can cooperate with a movable control switch to perform forward and backward.
(2) Imported deceleration motor is used to drive gear transmission, and the special wide PU friction wheel is used to rub against the floor to promote the movement of the stands. All motors in each part realize the expansion and contraction of independent modules, and special codes are equipped to ensure parallel between modules. Each code is controlled by a computer system.
(3) The driving system can ensure that when encountering ground defects and obstacles, it provides sufficient power and does not run off the track.
Drive mechanism: Electric control type, with infrared remote control and limited manual control. It adopts imported three-phase geared motor with electric power of 0.55KW and voltage of 380V. It has the characteristics of large reduction ratio, high efficiency, low noise, few failures and long life. The anti-deflection device is installed to ensure that the movable stand can be easily extended and contracted without deviation. The telescopic mechanism is flexible, has low working noise and does not scratch the floor.
It can be matched with a variety of styles of seats: low back, high back folding plastic seats, folding soft-pack seats, seats with armrests, etc., styles are optional. The plastic seat material is: high-density polyethylene (HDPE), the soft seat material: fireproof fiber + ergonomic memory foam.
