Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete engineering construction technology, in particular to a concrete layered deformation measuring die. Background Art
[0002] In engineering construction, the deformation of concrete structure is an important factor affecting the durability of concrete. The early deformation of concrete mainly includes shrinkage deformation, temperature deformation and stress deformation. These deformation phenomena will lead to the concentration of internal stress of concrete, the generation of cracks and other problems, thereby reducing the physical and mechanical properties of concrete and affecting its durability. Studies have shown that during the early hardening and molding process of concrete, large shrinkage deformation will occur, and the proportion of concrete cracks caused by shrinkage deformation is more than 80%. Therefore, it is very meaningful to explore the early shrinkage deformation of concrete and provide a more suitable layered deformation measurement mold.
[0003] For testing the early deformation of concrete, most of the current testing methods mainly test the concrete specimen as a whole, and explore the deformation of concrete by analyzing the changes in data. Although the deformation of concrete can be evaluated, its accuracy is questionable. At present, the exploration of concrete durability is becoming more and more in-depth, and the research on it is becoming more and more detailed. In order to more accurately explore the deformation inside the concrete, a mold for layered measurement of concrete deformation has been developed. The mold is cast in one layer and can be molded into multiple layers of concrete according to the research content and method, which will not destroy the original structure inside the concrete, and can be explored according to the actual situation of the project. It is convenient to accurately explore the deformation of different depths (different layers), and the deformation of concrete can be more accurately explored through the study of deformation at different depths.
[0004] For example, the patent applications with publication numbers CN106442945A and CN102269725A in the prior art do not disclose a structure in which a rotating structure cooperates with a layer partition plate, and cannot achieve the effect of layering concrete of different depths. Therefore, a concrete layering deformation measurement mold is needed to solve the above technical problems. Utility Model Content
[0005] In view of this, the utility model provides a concrete layered deformation measurement mold to solve the mutual interference problem between deformations of different depths during traditional concrete deformation measurement.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A concrete layered deformation measurement mold comprises a cylindrical steel mold, a rotating structure, a layer partition plate and a base. The rotating structure is installed on the base and is rotatably connected to the cylindrical steel mold. A plurality of cylindrical steel molds are distributed in sequence along the longitudinal direction and are rotatably connected to the rotating structure. A layer partition plate is provided between two adjacent cylindrical steel molds, and the layer partition plate is rotatably connected to the rotating structure.
[0008] Furthermore, the rotating structure includes a steel shaft and a plurality of rotating shafts distributed at intervals, the interlayer partition plate is rotatably connected to the steel shaft, the steel shaft is connected to the base via a threaded connection, and the rotating shaft is sleeved on the steel shaft and rotatably connected to the steel shaft.
[0009] Furthermore, the rotating shaft is divided into a first rotating shaft and a second rotating shaft, and the first rotating shaft and the second rotating shaft are sequentially distributed along the longitudinal direction and are rotatably connected to the steel shaft.
[0010] Furthermore, the cylindrical steel mold is formed by bolting two semi-cylindrical steel molds, and the two semi-cylindrical steel molds are fixedly connected to the first rotating shaft and the second rotating shaft respectively.
[0011] Furthermore, the diameter of the cylindrical steel mold is 150 mm and the height is 150 mm.
[0012] Furthermore, the inner side of the cylindrical steel mold and the interlayer partition plate are coated with anti-sticking oil.
[0013] The beneficial effects of the utility model are:
[0014] The utility model has strong flexibility, simple structure, easy operation, low cost and wide application range. It utilizes rotatable layer partition plates to layer the cylindrical steel molds filled with concrete, and can effectively separate the concrete for layered treatment without damaging the original structure inside the concrete. It can also increase or decrease the number of cylindrical steel molds and layer partition plates in turn according to the actual engineering situation or test needs, and flexibly change the number of forming layers, thereby simulating the actual engineering situation to test the deformation of concrete at different depths, and providing a more accurate testing method for exploring the durability of concrete.
