背景技术 Background technique
深基坑支撑体系一般为钢筋混凝土支撑和钢支撑两种，钢支撑因为安装与拆除方便，应用较为广泛。针对冠梁部位的钢支撑，为了应力扩散，在混凝土中预埋钢板，针对钢围檩部位的钢支撑，在钢围檩上焊接钢板。无论预埋钢板还是在围檩上焊接钢板，都是一次性的，材料浪费较大。 There are generally two types of support systems for deep foundation pits: reinforced concrete supports and steel supports. Steel supports are widely used because they are easy to install and dismantle. For the steel support of the crown beam, steel plates are pre-embedded in the concrete for the purpose of stress diffusion, and for the steel support of the steel purlins, steel plates are welded on the steel purlins. Both pre-embedded steel plates and welded steel plates on purlins are one-off, resulting in a large waste of materials.

图2为本装置实施例二支撑挂板结构示意图。 Fig. 2 is a schematic diagram of the structure of the supporting hanging plate of the second embodiment of the device.
具体实施方式 Detailed ways
包括支撑挂板1，支撑挂板1上连接钢支撑，如图1所示，所述支撑挂板1为“Z”形，支撑挂板1上端设有吊耳2和螺栓孔3，螺栓孔3连接膨胀螺栓锚固在冠梁上。
It includes a supporting
所述螺栓孔3设有1-3个。 There are 1-3 bolt holes 3.
包括钢围檩，钢围檩一端设有支撑挂板1，支撑挂板1上连接钢支撑，如图2所示，所述支撑挂板1为“L”形，支撑挂板1上端设有吊装孔4，支撑挂板1背面设有挂耳5，所述支撑挂板1经挂耳5挂在钢围檩上。
Including the steel purlin, one end of the steel purlin is provided with a supporting
所述挂耳5设有1-3个。 There are 1-3 hanging ears 5.
（1）将预埋在混凝土中的钢板变更为支撑挂板式，支撑挂板为16mm厚度的钢板，上表面通过膨胀螺栓锚固于冠梁上，待钢支撑拆除后，挂板可以摘取重复利用。 (1) Change the steel plate embedded in the concrete into a supporting hanging plate type. The supporting hanging plate is a steel plate with a thickness of 16mm. The upper surface is anchored to the crown beam by expansion bolts. After the steel support is removed, the hanging plate can be removed and reused .
（2）将焊接在钢围檩上的钢板变更为支撑挂板形式，待钢支撑拆除后，支撑挂板可以摘取重复利用。 (2) Change the steel plate welded on the steel purlin into the form of support hanging plate. After the steel support is removed, the support hanging plate can be removed and reused.
实施例 1、工程概况 Example 1. Project overview
以某地铁4号线为例，详细介绍支撑挂板使用过程。该地铁4号线某站全长168.8m，地下二层岛式站台。车站主体结构基坑开挖深度17.8m～18.1m，标准段宽度20.5m，扩大端宽度24.4m，共设计上中下3道钢支撑。 Taking a subway line 4 as an example, the use process of the support hanging board is introduced in detail. A station of the Metro Line 4 has a total length of 168.8m and an island platform on the second floor underground. The excavation depth of the foundation pit for the main structure of the station is 17.8m-18.1m, the width of the standard section is 20.5m, and the width of the enlarged end is 24.4m. A total of 3 steel supports are designed, the upper, middle, and lower.
施工期间，为了节约成本，将预埋在冠梁上的钢板变更为挂板式，后来又发展到将钢围檩上的焊接钢板变更为挂板式。经过实际应用后，感觉挂板在施工成本、施工进度方面具有很大作用。 During the construction period, in order to save costs, the steel plate pre-buried on the crown beam was changed to the hanging plate type, and later developed to change the welded steel plate on the steel purlin to the hanging plate type. After practical application, I feel that the hanging board has a great effect on the construction cost and construction progress.
2、实施效果 2. Implementation effect
（1）支撑挂板在钢支撑的应用中，只要防锈工作做好，可以重复使用十几次。本车站长度168.8m，共使用306块挂板，平均每块板60kg，306×60=18360kg，可以有效地降低工程成本。 (1) In the application of steel support, as long as the anti-rust work is done well, the supporting hanging plate can be reused more than ten times. The length of this station is 168.8m, and a total of 306 hanging panels are used, with an average of 60kg per panel, 306×60=18360kg, which can effectively reduce the project cost.
（2）支撑挂板采用工厂加工，使用时只需安装即可，与预埋钢板相比较，施工速度快。 (2) The supporting hanging plate is processed by the factory, and it only needs to be installed when it is used. Compared with the embedded steel plate, the construction speed is fast.
