关于礼堂椅的安装，有很多细节的地方需要我们注意。

There is a lot of details about the installation of the auditorium chair, we need to pay attention to the places.

1、确认场地的长和宽。 这是最重要的基础数据。确认场地内通道的数量（直、横各几条），预留通道的宽度（小会堂通道一般在120厘米左右，一般不小于100厘米，大会堂在180厘米左右，一般不小于150厘米）。

1, confirm the length and width. This is the most important basic data. Confirm the number of sites within the channel (straight, horizontal a few), the width of the reserved channel (small synagogue channel is in commonly 120 centimeters, is generally not less than 100 cm, in the great hall of the 180 cm, generally not less than 150 cm).

1)计算每排礼堂椅的数量：用场地总宽度减去预留通道的宽度，得出的数据除以礼堂椅宽，取整数，就是每排礼堂椅的数量。（国内每位礼堂椅的标准中对中座距宽度是57厘米，既：椅身宽49厘米、加一个扶手宽8厘米。根据客户的要求椅宽可在55—59厘米内调整确定）。然后的微调是最重要的，因为宽度除

1) calculate the amount of each row of the auditorium chairs, with total width minus the reserved channel width, the data calculated by dividing the auditorium chair width, rounded, is the number of each row of the auditorium chairs. (domestic each auditorium chair in the standard width of the focal distance is 57 cm, both: 49 cm wide, with a chair armrest 8 cm wide. According to the requirement of the customer chair can be adjusted within 55 to 59 cm wide). Then the fine-tuning is one of the most important, because the width

礼堂椅宽一般不可能是整数，礼堂椅的数量必须取整数，余数加在通道里。另外：每个单元（联坐）要多一个脚（8厘米），每排几个单元就得加几个8厘米。最后综合考虑客户的要求和通道的宽度，确定椅子的数量和通道的宽度。

Auditorium chair width generally can't be an integer, the number of auditorium chair must be rounded, the remainder in the tunnel. Sit in addition: each unit (al) to a foot (8 cm), a few units have to add a few rows 8 cm. Finally considering the customer's requirements and the width of the channel, determine the number of chairs, and the width of the channel.

2）计算排数：礼堂椅每排前后标准的宽度是100厘米，但最小不得小于90厘米，否则后排的写字板无法放下。用场地的总长度减去预留通道的宽度除以90或100厘米，取整数，就是总排数。两者相乘就是整个场地椅子的总数。这里特别要注意的是，场地如果是阶梯的，应以90—100厘米为单元砌台阶，多了没用，少了不行。如果是斜坡的，建筑设计图找不到了，可用多功能坡度测量仪（网上可以买到），多选几个点测量一下，取平均值。如遇弧形直径大于17米，按正常尺寸生产、安装。小于17米的具体情况具体处理。

2) calculate row number: auditorium chair before and after each row of the standard width is 100 cm, but the minimum is not less than 90 cm, the back of the tablet won't be able to put down. With the site minus the reserved channel width divided by the total length of 90 or 100 cm long, rounded, is the total number of rows. Multiply the total number of chairs is the whole site. Paying special attention to is here, the site if it is the ladder of, shall be made in 90-100 cm unit build by laying bricks or stones steps, no more, not less. If it's slope, architectural design, because I can't find available multi-function slope measuring instrument can buy (online), choose more a few points you measured, averaged. In case of arc 17 meters in diameter, according to the size of normal production, installation. Particular case is particular processing of less than 17 meters.AK-6021
