This document is a product manual for the TMG-GH1220, a 12Ft x 20Ft Tunnel Greenhouse Grow Tent manufactured by TMG Industrial.
Function Description:
The TMG-GH1220 is designed as a tunnel greenhouse or grow tent, providing a controlled environment for cultivating plants. Its primary function is to offer protection from external weather conditions, maintain a suitable climate for growth, and potentially extend growing seasons. The structure appears to be a semi-circular tunnel design, commonly used for maximizing internal space and light exposure. The inclusion of a "Film rolling machine" and "Roll film tube" suggests a mechanism for managing the greenhouse film, likely for ventilation or temperature control, allowing users to easily roll up or down sections of the film. The "Door buckle" indicates a secure entry point. The "Reed groove" and "Clip spring" components are typically used to secure the film tightly to the frame, ensuring a sealed environment. The "Pressure film carrier" further supports the secure attachment of the film. The overall design aims to create an optimal growing space for various agricultural or horticultural needs.
Important Technical Specifications:
- Model: TMG-GH1220
- Assembled Size (L x W x H): 6.5 m x 3.66 m x 2.2 m (21 ft x 12 ft x 7.2 ft)
- Shoulder Height: 1.2 m (4 ft)
- Door Size (W x H): 1.2 m x 1.8 m (4 ft x 6 ft)
- Frame Structure: Composed of various tubes including Peak arch tubes (6), Upper rafter tubes (12), Shoulder tubes (12), Sidewall tubes (12), and Roof purlins (25).
- Base Plates: 13 standard base plates and 2 door column base plates, secured with 30 expansion bolts (Φ 14x100mm).
- Door Frame Components: Includes Front door cross tubes (2), Rear door cross tubes (2), Upper vertical tubes for rear truss (1), Lower vertical tubes for rear truss (1), Door frame cross pull tube (1), Door frame left tube (1), Door frame right tube (1), Door frame column left tube (1), Door frame column right tube (1), and Door horizontal tubes (4).
- Film Management System: Features Roll film tubes (6 of one type, 2 of another), Film rolling machines (2), Film rolling machine guide tubes (2), Reed grooves (34), Clip springs (34), Eight clip springs (12), Pressure film carriers (12), and Tube clamps (6).
- Fasteners: A variety of bolts and screws are used for assembly: Half round head bolt M6x50 (40), Hex bolt M6x45 (60), Hex bolt M6x80 (2), Self tapping screw #12x25 (182), Self tapping screw #12x35 (4), and Self tapping screw #12x35 (62).
- Covering Material: Includes Top cover film (1 volume) and Front and rear film (2 volumes). The manual also mentions "Board (not included)" with a length of 34 meters, which is likely for securing the film or providing a base.
- Accessories: Socket wrench (1), Hex wrench (1), Square plugs (6), Round plugs (6), Braided rope (1 bundle, 20m), and Adhesive tape (1 volume).
Usage Features:
- Installation Site Selection: Emphasizes the importance of carefully marking the ground for base plate and door positions, ensuring diagonal measurements are equal for a square foundation. Base plates must be firmly installed with expansion bolts.
- Modular Truss Assembly: The greenhouse consists of 6 trusses, which are assembled using hex bolts. This modular design likely simplifies construction.
- Frame Protection: A critical feature highlighted is the recommendation to wrap adhesive tape (#34) around sharp points of joints on the trusses after assembly. This prevents friction between the fabric cover and the frame, extending the lifespan of the cover.
- Film Installation: The manual details the installation of front, rear, and roof films. It stresses the importance of pulling the roof cover evenly to eliminate wrinkles and ensure a flat, smooth surface, avoiding over-tightening to prevent damage. Clip springs (#22A) are used to fix the film.
- Roll Film System: The inclusion of film rolling machines (#21) and roll film tubes (#18) allows for horizontal and flexible raising and lowering of the film. Round plugs (#32) are used at the ends of the guide tubes, which are mounted to the frame with hex bolts (#27) to ensure free swinging. The film is wound onto the roll film tube and clamped with a pressure film carrier (#24). This system provides a practical way to manage ventilation and access.
- Door Buckle: A door buckle (#20) is included, indicating a secure closing mechanism for the entrance.
- Braided Rope: Braided rope (#33) is used in conjunction with eight clip springs (#23) for fastening, likely for securing the film or other structural elements.
Maintenance Features:
- Pre-Assembly Check: Users are instructed to read the manual completely, check all parts against the list, and wear proper safety gear (helmets, eyewear, clothing, safety harnesses for elevated work, proper ladder/cage operation).
- Wind Conditions for Assembly: Advises choosing a day with low or no wind for installation, as assembly can be difficult in heavy wind.
- Structural Integrity: Warns against making alterations to the structure or hanging weights on the frame during installation to prevent damage or injury. The manufacturer disclaims responsibility for damages from inappropriate installation, unauthorized modifications, or extreme weather.
- Film Protection: Recommends taping or adding foam/rubber to frame joints and where the frame touches the cover. This helps extend the cover's lifespan by reducing friction and wear.
- Post-Installation Inspection: Users are advised to periodically inspect the shelter to ensure all components are firmly secured and the structure is well-supported. This includes checking all bolts, nuts, and connection points.
- Snow Load Management: A crucial maintenance instruction is to immediately remove any snow from the roof and not leave snow load overnight. Maintaining 3 feet of clearance on all sides and preventing snow accumulation on the sides is essential to prevent inward pressure and potential collapse.
- Non-Occupancy: Explicitly states that the building is not intended for human occupancy, implying it's designed solely for cultivation or storage.
