結構網(wǎng)架屋面施工技術在大中型建筑結構中使用比較普遍,在大跨度以及大空間建筑結構中,螺栓球網(wǎng)架結構使用較多,突出優(yōu)點:重量輕、跨度大、剛度強、抗震性能和整體性好。當前,在體育館、影劇院、展覽館等大中型建筑結構中已經(jīng)廣泛使用。
Structural grid roof construction technology is commonly used in large and medium-sized building structures. In large-span and large-space building structures, bolted ball grid structures are used more, with outstanding advantages: light weight, large span, strong rigidity, seismic performance and Good integrity. At present, it has been widely used in large and medium-sized building structures such as stadiums, theaters, and exhibition halls.

網(wǎng)架安裝 Grid installation
1、安裝前準備工作 Preparation before installation
檢查網(wǎng)架支座軸線與標高、檢查支座混凝土強度、搭設滿堂紅腳手架并檢查各支點的位置與標高、用千斤頂調(diào)整臨時支點的網(wǎng)架高度。網(wǎng)架支座軸線以及標高設計要嚴格按照有關標準規(guī)定進行,嚴禁隨意進行;對于混凝土強度,必須符合設計要求與國家現(xiàn)行標準;搭設的腳手架要詳細布置臨時支點,經(jīng)過計算準確得出臨時支點的位置和數(shù)量;臨時支點的網(wǎng)架高度必須使用千斤頂嚴格調(diào)整。
Check the axis and elevation of the grid support, check the concrete strength of the support, set up full red scaffolding, check the position and elevation of each support point, and adjust the height of the temporary support grid with a jack. The grid support axis and elevation design should be carried out in strict accordance with the relevant standards and regulations, and it is strictly prohibited to carry out at will; for the concrete strength, it must meet the design requirements and the current national standards; the erected scaffolding should be arranged in detail with temporary support points, and the temporary support points should be accurately calculated after calculation Location and quantity; the height of the grid frame of the temporary fulcrum must be strictly adjusted with a jack.
2、安裝工藝流程 Installation process
(1)具體安裝步驟安裝底部弦桿和底部弦球:每個安裝球都編號,根據(jù)固定的底部球數(shù)的數(shù)量確定連接后的底部和弦,與對角線尺寸測量和其他結束的水平,右后焊接。
Specific installation steps: Install the bottom chord and the bottom chord ball: each installation ball is numbered, the bottom chord after the connection is determined according to the number of fixed bottom balls, and the diagonal size measurement and other end levels are welded to the right.
下弦桿與下弦球的安裝:施工前,將每一個安裝球?qū)粋€編號,施工的過程中可以根據(jù)編號對下弦球進行固定以確定中心,然后將下弦球連接下弦桿,測量方式為對角尺寸測量,而且應與另一頭作為基準,確定之后方可進行點焊。
