梁、板、柱完整的造价计算书及计算规范!

1、 柱子工程量

(1)柱子体积:砖柱;砼柱

(2)砼柱模板

(3)砼柱高度超过3.6m增价

(4)独立柱装修

(5)柱侧装修

2、柱子工程量计算方法

(1)构造柱工程量计算

①构造柱体积=构造柱体积+马牙差体积

其中马牙槎体积=马牙槎与墙相交宽度*马牙槎嵌入墙内的长度(0.03)*构造柱高度

②构造柱模板=构造柱模板+马牙差模板

马牙槎模板面积=马牙槎嵌入墙内的长度(0.03)*构造柱高度

(2)构造柱工程量计算的难点

①构造柱的马牙差算起来很麻烦,必须考虑柱子与几个墙面相交。

②模板计算难点同体积。

(3)框架柱

①现浇混凝土柱按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件所占体积。

框架柱体积=框架柱截面积*框架柱柱高

其中柱高:

a有梁板的柱高,应自柱基上表面(或楼板上表面)至上一层楼板上表面之间的高度计算。

b无梁板的柱高,应自柱基上表面(或楼板上表面)至柱帽下表面之间的高度计算。

c框架柱的柱高,应自柱基上表面至柱顶高度计算。

②框架柱的模板=框架柱周长*框架柱支模高度

天津2004计算规则:混凝土、钢筋混凝土模板及支架按照设计施工图示混凝土体积计算。

③预制混凝土柱按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件所占体积,柱上的钢牛腿按铁件计算.

(4)砼柱高度超过3.6m增价=砼柱高度超过3.6m的墙体体积总和

(5)独立柱装修=框架柱周长*装修高度

(6)柱侧装修=柱外露长度*装修高度

1、梁工程量

(1)梁体积 

(2)梁模板 

(3)梁高度超过3.6m增价 

(4)梁侧装修

2、梁工程量计算方法

(1)梁的体积=梁的截面面积*梁的长度

现浇混凝土梁按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件所占体积,伸入墙内的梁头、梁垫并入梁体积内。

①梁与柱连接时,梁长算至柱侧面,主梁与次梁连接时,次梁长算至主梁侧面。

②圈梁与梁连接时,圈梁体积应扣除伸入圈梁内的梁的体积。

③在圈梁部位挑出的混凝土檐,其挑出部分在12cm以内时,并入圈梁体积内计算;挑出部分在12cm以外时,以圈梁外皮为界限,挑出部分为挑檐天沟。

④预制混凝土梁按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件所占体积。

(2)梁的模板面积=(梁侧面高之和+梁底)*梁的长度

天津2004计算规则:混凝土、钢筋混凝土模板及支架按照设计施工图示混凝土体积计算。

(3)砼梁高度超过3.6m增价=砼梁高度超过3.6m的墙体体积总和

(4)梁侧装修=梁外露长度*装修长度

3、梁工程量计算的难点

(1)梁的体积计算,要考虑与柱子、砼墙、梁相交时的扣减情况。

(2)梁的模板不好计算,要考虑净长度。

过梁

1、过梁工程量

(1)过梁体积:砖过梁;砼过梁

(2)砼过梁模板

(3)挑出部分装修

2、 过梁计算

(1)过梁的体积

过梁的体积=过梁截面面积×过梁的长度

(2)过梁的模板

过梁模板面积=过梁的底模+过梁的侧模

①过梁的侧模=洞口净长度×过梁宽度

②过梁侧模=过梁侧面长度之和×过梁高度

(3)挑出部分装修=过梁侧面长度*过梁外露宽度

3、 过梁工程量计算难点

(1)矩形、异形过梁计算时必须考虑过梁与墙相交的情况,计算嵌墙体积;

(2)矩形、异形过梁计算时必须注意过梁的标高和圈梁的标高考虑过梁与圈相交的扣减。

1、板工程量

(1)板体积 

(2)板模板  

(3)板高度超过3.6m增价 

(4)预制板

2、板的工程量计算

(1)板的体积=板的面积×板的厚度

现浇混凝土板按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件及单个面积0.3m2以内的孔洞所占体积。

有梁板(包括主、次梁与板)按梁、板体积之和计算,无梁板按板和柱帽体积之和计算,各类板伸入墙内的板头并入板体积内计算,薄壳板的肋、基梁并入薄壳体积内计算。

预制混凝土板按设计图示尺寸以体积计算。不扣除构件内钢筋、预埋铁件及单个尺寸300mm×300mm以内的孔洞所占体积,扣除空心板空洞体积。

(2)板的模板=板的底模+板的周边模板

板的底模=板的底面净面积

板的周边模板=板的外露周边长度×板的厚度

天津2004计算规则:混凝土、钢筋混凝土模板及支架按照设计施工图示混凝土体积计算。

(3)砼梁高度超过3.6m增价=砼梁高度超过3.6m的墙体体积总和

(4)预制板

3、板的工程量计算的难点

(1)异形板板的面积的计算比较麻烦;

(2)计算模板时板的底面净面积比较麻烦;

(3)计算模板时板的外漏周边长度比较麻烦;

(4)无梁板要计算柱帽体积。

    Great post right here. One thing I would like to say is that most professional domains consider the Bachelor’s Degree as the entry level standard for an online education. Although Associate Certifications are a great way to get started on, completing a person’s Bachelors reveals many entrance doors to various employment opportunities, there are numerous on-line Bachelor Diploma Programs available through institutions like The University of Phoenix, Intercontinental University Online and Kaplan. Another concern is that many brick and mortar institutions provide Online versions of their diplomas but generally for a drastically higher cost than the institutions that specialize in online degree plans.
