Abstract
Description
技术领域technical field
本申请涉及建筑结构。This application relates to architectural structures.
背景技术：Background technique:
在建筑结构中，现有钢筋混凝土梁都是实心结构，自重大，用材多，需要发明设计一种能够显著降低自重的钢筋混凝土新型结构梁。In the building structure, the existing reinforced concrete beams are all solid structures, with heavy weight and many materials. It is necessary to invent and design a new type of reinforced concrete structural beam that can significantly reduce the dead weight.
发明内容Contents of the invention
本发明目的是降低钢筋混凝土梁的自重，具体技术方案是：The purpose of the invention is to reduce the self-weight of reinforced concrete beams, and the concrete technical scheme is:
1、在钢筋混凝土梁中心位置套上一根管子即内套管，使钢筋混凝土梁成空心结构；1. Put a pipe in the center of the reinforced concrete beam, that is, the inner casing, so that the reinforced concrete beam becomes a hollow structure;
2、内套管可以是PVC-U管、钢塑复合管等，圆管方管均可；2. The inner casing can be PVC-U pipe, steel-plastic composite pipe, etc., round or square;
3、内套管中可以布设电缆线、网线等。3. Cables, network cables, etc. can be laid in the inner casing.
本申请的积极效果是：The positive effect of this application is:
(1)降低钢筋混凝土梁的自重，节约混凝土材料；(1) Reduce the self-weight of reinforced concrete beams and save concrete materials;
(2)梁可以兼做建筑穿线管。(2) The beam can also be used as a building threading pipe.
附图说明Description of drawings
图1是空心型钢筋混凝土梁的断面示意图，图中：1——钢筋混凝土；2——内套管。Figure 1 is a schematic cross-sectional view of a hollow reinforced concrete beam, in which: 1—reinforced concrete; 2—inner casing.
具体实施方式Detailed ways
如图1所示，在浇筑钢筋混凝土梁之前，先把内套管水平放入模板中央，并与四周模板固定，然后在模板和内套管之间浇筑自流平混凝土，经过养护硬化达到一定强度后，拆除模板，即成空心型钢筋混凝土梁。As shown in Figure 1, before pouring reinforced concrete beams, put the inner casing horizontally into the center of the formwork and fix it with the surrounding formwork, then pour self-leveling concrete between the formwork and the inner casing, and harden to a certain strength after curing Finally, the formwork is removed to form a hollow reinforced concrete beam.
