Abstract

一种薄壁倒开口箱梁,包括连板、主板、横格板。 其优点自重轻,轻一般梁的30~60%,消耗材料省, 省混凝土30~50%,省钢材20~30%。预制、吊装 十分方便,可制作大垮度的梁,垮度可达30米以上, 可缩短施工工期。

Description

本实用新型涉及建筑技术领域,具体地说是一种薄壁倒开口箱梁。
现有的建筑物中用的梁多半是实心梁,此比梁的自重重,消耗材料多,而且梁的垮度由于自重重受到限制。梁的预制,吊装都由重量问题受到限制。
本实用新型的目的是设计一种自重轻,预制、吊装方便,垮度大的薄壁倒口箱梁。
本实用新型薄壁倒开口箱梁包括高度和厚度之比大于10的主板,高、厚之比大于10的横格板,连接两主板的连板。
主板、横格板、连板都是用钢筋混凝土浇灌而成。
本实用新型的优点是倒开口箱梁的自重轻,较一般梁轻30~60%,消耗材料少,省混凝土30~50%,省钢材20~30%,预制、吊装十分方便,可作大垮度的梁,垮度可达30m以上,可缩短施工工期。
下面结合附图对实施例作详细说明:
图1为薄壁倒开口箱梁剖视图。
图2为薄壁倒开口箱梁仰视图。
图3为薄壁倒开口箱梁实施例钢筋配置图。
根据图1、图2、图3所示,按图3钢筋配置图把钢筋摁牢,做主板(1)、横格板(2)、连接(3)骨架,然后浇灌水泥混凝土,震动,抹平滑,则倒开口箱梁制成。开口箱梁的主板(1)和连板(3)相连,横格板(2)和两主板(1)和连板(3)相连,其主板(1)和横格板(2)的厚、高度之比大于10。
