技术领域technical field
本发明涉及装配式混凝土模型结构施工领域,特别涉及一种装配式剪力墙模型结构整体模具,可用于例如以“口”型为基本单元组成建筑平面图的现浇剪力墙模型结构或装配式剪力墙模型结构的制作。The present invention relates to the construction field of prefabricated concrete model structures, in particular to an integral mold for prefabricated shear wall model structures, which can be used for cast-in-place shear wall model structures or prefabricated model structures such as "mouth" as the basic unit to form a building plan. Fabrication of shear wall model structures.
背景技术Background technique
在土木工程领域,为检验新的结构设计理论或新的结构体系,一般是通过模型结构试验研究对其进行检验或验证。模型结构是通过几何缩尺后,按照一定的相似理论进行设计计算并制作。对于剪力墙模型结构,层高一般为300mm~800mm,墙厚度为20mm~50mm,洞口尺寸及墙厚较小,加之应用低强度及低弹性模量混凝土,后期模板较难拆除,暴力拆模会对模型结构造成损害,进一步影响试验结果的准确性。对于装配式剪力墙模型结构,按照原型结构的施工工艺,模型结构墙体混凝土应分两次浇筑,在预制墙体和现浇部位接触部位形成竖向分隔缝,如何在模型结构钢筋绑扎阶段设置合理有效的分隔装置,并与模板相结合,是一个难题。In the field of civil engineering, in order to test new structural design theories or new structural systems, it is generally tested or verified through model structural test research. The model structure is designed, calculated and produced according to a certain similarity theory after geometric scaling. For the shear wall model structure, the storey height is generally 300mm-800mm, the wall thickness is 20mm-50mm, the opening size and wall thickness are small, and the low-strength and low-elastic modulus concrete is used, and the later formwork is difficult to remove. It will cause damage to the model structure and further affect the accuracy of the test results. For the prefabricated shear wall model structure, according to the construction technology of the prototype structure, the concrete of the model structure wall should be poured twice, and a vertical separation joint should be formed at the contact part between the prefabricated wall and the cast-in-place part. It is a difficult problem to set up a reasonable and effective partition device and combine it with the formwork.
传统的大比尺模型结构用木模板或泡沫制作,木模板不易拆除且重复利用的次数较低,泡沫制作时,造价较高,制作完成的模型结构表面粗糙,棱角模糊。The traditional large-scale model structure is made of wooden formwork or foam. Wooden formwork is not easy to dismantle and the number of times of reuse is low. When making foam, the cost is high, and the finished model structure has a rough surface and fuzzy edges and corners.
