Description
Technical field
The utility model is related to construction to monitor field, refers in particular to a kind of template displacement monitor.
Background technology
In the construction work of cast-in-place column or shear wall, due to management or misoperation, it often will appear swollen mould phenomenon, lead
Cast-in-place part local thickness is caused to increase or occur voids and pits phenomenon or even quick-fried mould accident occurs, increases construction cost even right
Agent structure has an impact.
The reason of generating swollen mould phenomenon mainly has the following：
1. current pump concrete dosage is larger, in order to ensure the pumpability of pump concrete, often in pump concrete
Middle to add in suitable air entraining agent, some air entraining agents form larger bubble in concrete, and surface can be relatively low, it is easy to shape
Into connectivity air pocket, if unreasonable along with vibrating, air pocket cannot be completely exhausted out, and can give hardened concrete structure surface
Cause voids and pits.
2.《GB/T10-95 Concrete Pumping Construction technical regulations》6.3.4 " concrete pours into a mould lift height to middle regulation, preferably
For 300-500mm, but in practice of construction, it is all higher often to pour into a mould thickness, since bubble pathway length is long, even if vibrate when
Between reach regulatory requirements, bubble can not be completely exhausted out, and also can cause voids and pits to hardened concrete structure surface in this way.
3. it at present in the construction process, since template is not fixed firm in installation process, is led usually using plank sheathing
Template is caused to shift in process of vibrating is poured, shear wall local size is made to generate deviation.
It after swollen mould occurs, can be solved by the method for artificial chipping, but not only waste of materials, but also it is numerous to construct in this way
It is trivial, increase construction cost.Therefore, it is preferable to solution be that the displacement of template is monitored in real time during construction.
When in the engineering of casting concrete larger displacement occurs for template, stop pouring and handling template in time, so as to keep away
