一、穩(wěn)固的結構設計

1、 Stable structural design

1.框架結構

1. Framework structure

濟南推拉棚的框架多采用高強度的金屬管材作為支撐骨架，常見的有鍍鋅鋼管和鋁合金管。鍍鋅鋼管以其較高的強度和良好的耐腐蝕性，成為眾多推拉棚的。其管壁厚度通常在 1.2 - 2.0mm 之間，管徑依據棚體大小而定，大型推拉棚一般采用直徑 32 - 50mm 的管材，小型棚體則使用直徑 25 - 32mm 的管材。各管材之間通過焊接、螺絲連接或專用連接件進行組裝，形成穩(wěn)固的矩形或拱形框架結構。

The frame of Jinan push-pull shed often uses high-strength metal pipes as the supporting skeleton, commonly including galvanized steel pipes and aluminum alloy pipes. Galvanized steel pipes have become the preferred choice for many sliding sheds due to their high strength and good corrosion resistance. The thickness of the pipe wall is usually between 1.2-2.0mm, and the diameter of the pipe depends on the size of the shed. Large push-pull sheds generally use pipes with a diameter of 32-50mm, while small sheds use pipes with a diameter of 25-32mm. The pipes are assembled through welding, screw connections, or specialized connectors to form a stable rectangular or arched frame structure.

鋁合金管框架的推拉棚則具有重量輕、美觀性好的特點，常用于對外觀要求較高的商業(yè)場所。鋁合金材質經過特殊處理，具備較強的抗腐蝕能力，且顏色多樣，可與周邊環(huán)境相協(xié)調。其結構設計同樣注重穩(wěn)固性，通過科學的力學計算，合理分布管材，確保棚體在承受風壓、雪載時保持穩(wěn)定。

The push-pull shed with aluminum alloy tube frame has the characteristics of light weight and good aesthetics, and is commonly used in commercial places with high appearance requirements. Aluminum alloy material has undergone special treatment, possessing strong corrosion resistance and diverse colors, which can coordinate with the surrounding environment. The structural design also emphasizes stability, and through scientific mechanical calculations and reasonable distribution of pipes, ensures that the shed remains stable under wind pressure and snow load.

2.滑輪與軌道系統(tǒng)

2. Pulley and track system

滑輪與軌道是推拉棚實現(xiàn)靈活推拉功能的關鍵部件?；喴话悴捎媚猃埢虿讳P鋼材質，尼龍滑輪具有耐磨、靜音的優(yōu)點，不銹鋼滑輪則強度更高、使用壽命更長。軌道通常安裝在地面或墻體上，分為單軌和雙軌兩種形式。單軌適用于小型推拉棚，結構簡單，成本較低；雙軌則更適合大型棚體，能夠提供更好的穩(wěn)定性和承重能力，使推拉過程更加順暢?；喤c軌道的配合精度直接影響推拉棚的使用體驗，的滑輪與軌道系統(tǒng)可確保棚體推拉輕松自如，且不易出現(xiàn)卡頓現(xiàn)象。

The pulley and track are key components for the flexible push-pull function of the push-pull shed. Pulleys are generally made of nylon or stainless steel materials. Nylon pulleys have the advantages of wear resistance and noise reduction, while stainless steel pulleys have higher strength and longer service life. Tracks are usually installed on the ground or walls, and are divided into two forms: single track and double track. Monorail is suitable for small push-pull sheds, with a simple structure and low cost; Double track is more suitable for large sheds, providing better stability and load-bearing capacity, making the pushing and pulling process smoother. The precision of the coordination between the pulley and the track directly affects the user experience of the push-pull shed. A high-quality pulley and track system can ensure that the shed can be pushed and pulled easily and smoothly, and is not prone to jamming.

3.支撐與加固結構

3. Supporting and reinforcing structures

為增強推拉棚的穩(wěn)定性，在框架結構基礎上，還會設置支撐與加固結構。常見的有斜撐桿和拉筋。斜撐桿一般安裝在框架的四角或側面，與地面形成一定角度，將棚體的壓力分散到地面，提高抗風能力。拉筋則橫向或斜向連接框架的不同部位，增加框架的整體剛性，防止棚體在受力時發(fā)生變形。在濟南多風的季節(jié)，這些支撐與加固結構能有效保障推拉棚的，避免被大風掀翻或損壞。

To enhance the stability of the push-pull shed, support and reinforcement structures will also be installed on the basis of the frame structure. The common ones are diagonal braces and braces. Diagonal struts are generally installed at the four corners or sides of the frame to form a certain angle with the ground to distribute the pressure of the shed to the ground and improve the wind resistance. Stretching connects different parts of the frame horizontally or diagonally, increasing the overall rigidity of the frame and preventing deformation of the shed under stress. During the windy season in Jinan, these support and reinforcement structures can effectively ensure the safety of the push-pull shed and prevent it from being overturned or damaged by strong winds.

二、材質選擇

2、 Material selection

篷布常用 PVC 涂層布、刀刮布和帆布。PVC 涂層布防水防曬、顏色多；刀刮布強度高、耐磨抗污；帆布透氣便宜，但耐用性和防曬差些。配件像連接件、螺絲，一般選不銹鋼或高強度塑料。不銹鋼結實耐腐蝕，塑料輕便成本低，好的配件能讓推拉棚用得久、推拉順滑。

PVC coated cloth, knife scraping cloth, and canvas are commonly used for tarpaulins. PVC coated fabric is waterproof, sun resistant, and comes in multiple colors; The knife scraping cloth has high strength, wear resistance, and stain resistance; Canvas is breathable and cheap, but its durability and sun protection are inferior. Accessories such as connectors and screws are usually made of stainless steel or high-strength plastic. Stainless steel is sturdy and corrosion-resistant, plastic is lightweight and cost-effective, and good accessories can make the sliding shed last long and smooth.

了解這些，無論是買推拉棚，還是日常維護，都能更得心應手，讓推拉棚更好地服務生活。??

By understanding these, whether it is buying a sliding shed or daily maintenance, one can be more adept and make the sliding shed better serve life. ??
