the City mountain road was built. The old house in the 60s of last century has been discarded as a dangerous building. Meng Min, a reporter of our newspaper, recently, the provincial government issued a "opinion on further improving the quality of the building", and clearly stated that the normal service life of the general building should not be less than 50 years, and the commemorative buildings and important buildings should not be less than 100 years. Are there any old buildings with 50 years of life in the provincial capital? What kind of problems are they facing? On the 8 day, the reporters conducted an investigation.
the old houses in old towns have become isolated island
the old dilapidated houses in Ji'nan are mainly concentrated in the old urban area. Shaw, who lives in the new village of the new village, is more than 60 years old this year. It is the old Ji'nan, the new village of the liberated bridge, the 27 new village of the heroic mountain road, the new village of the worker, the old Ji'nan.
since the completion of the construction of the new village on Shan Da Nan Road in 1978, Ms. Zhang has lived here. This place is convenient to buy things and children to go to school. Only the old age, the old house is not good to live. Ms. Zhang listed the disadvantages of the old house one by one: the unreasonable road and the Huxing design, and the old walls and doors and windows. The old house is inundated with the dense shops in the new residential area, like an isolated island.
seeing the old residents moving away from the island one by one, Mrs. Zhang is very envious. The house is too small, there is no heating, gas, and life is not convenient. But there is no other house, Ms. Zhang will continue to live here, although the quality of the old house is worried, but she can not afford to repair the cost, overhaul costs too expensive, not the laid-off workers can afford.
Huaiyin District and Tianqiao District, the five li ditch, the North pagoda tree, the South Xin Zhuang, the weir seven road and the south big Huai tree area are also the place where the old houses are concentrated. In the area of three latitude and eight old houses in Huaiyin District, an old household said that the old house with a ridge was more than 50 years old, and there was a time of thirty years before liberation. Later, according to the guidance of the elderly, the reporter came to an old building and found that it was a German building, which has been listed as a cultural relic, but it is full of tenants. The quality is good except that the roof leaks.
new room floor window is not conducive to building energy saving
8 morning, the reporter in Ji'nan green city whole village in Ji'nan, many buildings are floor windows. This is the residential area with large area of French windows, which has better lighting and vision. Mr. Li, who stayed in the second half of 2010, said that the winter windows were definitely not as good as the French windows. However, most of the French windows are used in high-grade residential buildings, villas and office buildings, while ordinary houses are relatively few.
according to Mr. Liang, according to Mr. Liang, the general trend in Ji'nan is to develop eastward. The newly built houses are based on the Olympic body center, and the East is generally built after 2009. Many residential districts have adopted the floor window design, and the old residential areas generally use single layer glass, and the newly built floor window houses are usually double glazed. The effect of heat preservation.
to the effect of the landing window, the Shandong provincial housing construction department wall to the energy saving research fellow, Zhu Chuansheng said that the energy conservation in the wall insulation is only one aspect, the weakest link is the door and window. If the landing window is used, the area ratio of window to wall will increase, and the greater the proportion, the more unfavorable to energy saving. In general, the thermal properties of windows and walls are 4-5 times different. If the windows are adopted, hollow and low radiation windows are generally adopted. This window is very expensive and consumes more energy, especially in public buildings. If the glass curtain wall is used in public buildings, besides high cost and high energy consumption, heavy light pollution will also be added.
