1. Anti corrosion and fire protection performance of wooden houses

　　木質房屋的耐火性能是目前普遍存在的問題之一。

　　The fire resistance of wooden house is one of the common problems at present.

　　在原木屋中，木屋是我國唯一取得原木屋外墻、間隔墻先進消防標識的企業。2015 - 2016年，我們委托中國固定滅火系統及耐火構件質量監督檢驗中心對常用105mm墻體進行耐火性能測試。根據GB/T9978.1的有關規定，確定了豎向承重構件的耐火承載力、整體性和保溫性。我公司生產的木質房屋耐火承載力、耐火完整性、保溫均大于1.00h，符合規范要求。

　　Among the original wooden houses, the wooden house is the only enterprise in China that has obtained advanced fire-fighting signs for the exterior walls and partition walls of the original wooden house. From 2015 to 2016, we entrusted China fixed fire extinguishing system and fire-resistant component quality supervision and inspection center to test the fire resistance performance of commonly used 105mm walls. According to the relevant provisions of GB / t9978.1, the fire-resistant bearing capacity, integrity and thermal insulation of vertical bearing members are determined. The fire-resistant bearing capacity, fire-resistant integrity and thermal insulation of the wooden houses produced by our company are all greater than 1.00h, meeting the specification requirements.

　　輕木和梁柱結構在歐洲、美國、日本等發達國家發展比較成熟，形成了完善的施工程序和體系。世界范圍的統計數據表明，沒有證據表明木制房屋比混凝土房屋更容易著火。輕木框架結構一般采用合格的耐火材料，按施工要求施工，具有良好的耐火性能。木結構內墻板和建筑蓋板通常采用石膏板、水泥纖維板等材料作為保護層，墻和地板結構的防火性能主要取決于這層保護層材料的防火性能。石膏板是常用的防護材料，分為防火石膏板和普通石膏板，通常采用攻絲螺釘將石膏板直接連接在木龍骨或木龍骨上。不同類型和厚度的石膏板可以提供0.5到3.0小時的最大耐火時間。

　　The development of light wood and beam column structure is relatively mature in Europe, America, Japan and other developed countries, forming a perfect construction procedure and system. Worldwide statistics show that there is no evidence that wooden houses are more likely to catch fire than concrete houses. Generally, the light wood frame structure adopts the qualified refractory materials, which are constructed according to the construction requirements and have good fire resistance performance. Gypsum board, cement fiber board and other materials are usually used as the protective layer for the interior wall board and building cover plate of wood structure. The fire performance of the wall and floor structure mainly depends on the fire performance of the protective layer materials. Gypsum board is a common protective material, which is divided into fire-proof gypsum board and common gypsum board. Usually, tapping screws are used to directly connect the gypsum board to the wooden keel or wooden keel. Gypsum boards of different types and thicknesses can provide a maximum fire resistance of 0.5 to 3.0 hours.

　　2. 木質房屋的保溫性能

　　2. Thermal insulation performance of wooden house

　　木材是一種天然的絕緣材料，因為它的細胞結構，有數百萬個小孔。由于材料的導熱系數隨其相對密度的增加而增加，木材的保溫性能優于高密度材料，高密度材料的保溫性能約為混凝土和砌體的10倍，是實心鋼的400倍。原木別墅外墻厚度分別為70、90、105、136毫米等規格。在超薄70mm墻體上，其保溫性能也相當于700mm厚的混凝土和砌體墻(混凝土和砌體墻一般為240mm厚)。

　　Wood is a natural insulating material, because of its cellular structure, there are millions of small holes. As the thermal conductivity of the material increases with the increase of its relative density, the thermal insulation performance of wood is better than that of high-density material, the thermal insulation performance of high-density material is about 10 times that of concrete and masonry, and 400 times that of solid steel. The external wall thickness of log villa is 70, 90, 105 and 136 mm respectively. On the ultra-thin 70mm wall, its insulation performance is also equivalent to 700mm thick concrete and masonry wall (concrete and masonry wall are generally 240mm thick).

　　輕型木結構房屋的保溫效果是由墻體、屋面、地面等有效保溫材料共同作用的結果。而熱效率高，是其柵欄結構的關鍵，從內到外由六層組成:墻襯(通常是防火石膏板的形式),防潮層(通常是一個聚乙烯薄膜),1不可燃的絕緣層(通常填充墻龍骨之間的玻璃纖維棉、屋頂的隔熱材料鋪設屋頂和地板格柵之間的間隙),外墻結構基板,建筑的通風功能,外墻裝飾面板的呼吸。

　　The heat preservation effect of light wood structure building is the result of effective heat preservation materials such as wall, roof and floor. High thermal efficiency is the key to its fence structure, which is composed of six layers from the inside to the outside: wall lining (usually in the form of fire-proof gypsum board), damp proof layer (usually a polyethylene film), 1 non combustible insulation layer (usually filled with glass fiber cotton between the wall keel, the gap between the roof and the floor grid laid by the roof insulation material), external wall structure base plate, ventilation function of the building, The breath of the exterior wall decoration panel.

　　當使用相同的玻璃纖維或泡沫作為保溫材料時，木屋的保溫性能比鋼結構好15%到70%。它可以大大降低建筑物的能源消耗。冬季室外溫度相同時，木屋室內溫度比混凝土結構高6℃。夏天正好相反。木質房屋墻體材料和磚混結構墻體的保溫性能可大大節省空調、空調電費和燃氣。研究表明，木制房屋可以節省高達60%的能源。

　　When using the same glass fiber or foam as insulation material, the heat preservation performance of the wooden house is 15% to 70% better than that of the steel structure. It can greatly reduce the energy consumption of buildings. When the outdoor temperature is the same in winter, the indoor temperature of wooden house is 6 ℃ higher than that of concrete structure. Summer is the opposite. The thermal insulation performance of wood building wall material and brick concrete structure wall can greatly save air conditioning, air conditioning electricity and gas. Research shows that wooden houses can save up to 60% of energy.

　　3.木質房屋具有防腐隔音性能

　　3. The wooden house has anti-corrosion and sound insulation performance

　　木質房屋的隔聲性能也優于磚混結構等其他結構形式。輕質木結構房屋的墻體和地板上填充的玻璃纖維棉或巖棉等保溫材料也是良好的隔音材料，可以減少聲音的傳播。在磚混結構中，沒有常見的撞擊噪聲傳遞問題。相同厚度的玻璃纖維棉或巖棉的保溫效果是混凝土的8-12倍，降噪吸聲效果是混凝土的4倍。實際測試結果表明，50mm厚的玻璃纖維棉或巖棉可以降低噪音50dB。具有隔聲要求的各類功能建筑或墻體可采用不同的形式來滿足隔聲要求。輕木建筑結構的空腔填充玻璃纖維羊毛或巖棉的50毫米厚的雙層,加上金屬保溫板(掛外板)、石膏板和竹子木纖維板(吊板內),其隔音性能可以達到相同厚度的磚墻的30倍。如果對隔音的要求很高，那么增加一部分的費用，也可以達到隔音的目的。

　　The sound insulation performance of wooden building is also better than other structural forms such as brick concrete structure. The thermal insulation materials such as glass fiber cotton or rock wool filled on the wall and floor of the light wood structure house are also good sound insulation materials, which can reduce the transmission of sound. In brick concrete structure, there is no common problem of transmission of impact noise. The heat preservation effect of glass fiber cotton or rock wool with the same thickness is 8-12 times that of concrete, and the noise reduction and absorption effect is 4 times that of concrete. The actual test results show that 50 mm thick fiberglass wool or rock wool can reduce the noise by 50 dB. Various functional buildings or walls with sound insulation requirements can adopt different forms to meet the sound insulation requirements. The cavity of the light wood building structure is filled with 50 mm thick double layers of glass fiber wool or rock wool, plus the metal insulation board (hanging outer board), gypsum board and bamboo wood fiber board (hanging board), its sound insulation performance can reach 30 times of the brick wall of the same thickness. If the requirements for sound insulation are very high, the purpose of sound insulation can also be achieved by increasing part of the cost.
