Description
Technical field
The utility model relates to a kind of concrete load applying device for endurancing.
Background technology
Traditional for studying Durability of Concrete time load application test unit, or due to loading range too little, or due to test unit easily unstability itself, or due to problems such as loading efficiency are low, applicability is poor, and the test figure drawn is inaccurate, greatly have impact on test findings.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide the concrete load applying device for endurancing that a kind of structure is simple, load successful.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: for the concrete load applying device of endurancing, comprise and be positioned at a left side, the spill pull bar of right both sides, at least two concrete prisms crouch successively from top to bottom and are placed on the recess of two spill pull bars, on, two first rod irons are placed with in the direction paralleled with two spill pull bars between lower two adjacent concrete prisms, each spill pull bar two threaded upper ends place is arranged with concavity packing washer from bottom to top respectively successively, stage clip and set nut, the second rod iron be provided with between described spill pull bar two upper end is through set nut, stage clip, spill packing washer is exerted pressure and pushes down superposed concrete prism.
Further, described concrete prism and two spill pull bars are clearance fit.
Further, described stage clip is automobile die springs.
Further, the diameter of described first rod iron is 25mm.
Further, described spill pull bar is made up of circular rod member.
Compared with prior art, the utility model has following beneficial effect: the utility model calculates the compression displacement of stage clip according to the payload values of required applying, is realized the compression displacement of stage clip by upper and lower spiral lock jack panel, accomplishes that accurate displacement loads; Owing to needing to consider that many group leaders phase loads as tests such as anti-carbonization, chloride-penetration resistances in endurancing simultaneously, this charger principle is simple and clear, easy and simple to handle, with low cost, repeat usage is high, compact, the error caused due to temperature is very little, load successful, reach the self-equilibrating of self, large batch of endurancing in a short time can be met; , in whole process of the test, substantially there is not the phenomenon of stress relaxation in the utility model loading system dependable performance.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
