Description
Technical field
The utility model relates to a kind of test unit of structural strengthening industry, particularly a kind of structural strengthening pre-stressed carbon fiber beaverboard anchorage system stretching force test unit.
Background technology
Pre-stressed carbon fiber plate technique is a novel Reinforcement technology, compared with traditional sticking carbon fiber plate technique reinforcement technique, this technology can make carbon fiber board just be in higher stress level before the load stress bearing structure transmission, play certain intensity in advance, thus realize making full use of of its high-strength performance.
Pre-stressed carbon fiber plate strengthening construction has the requirement of intensity to ground tackle and carbon fiber board when Shi Hanzhang, so need to carry out construction simulation test to pre-stressed carbon fiber beaverboard anchorage system.At present, conventional pre-stressed carbon fiber beaverboard anchorage system stretching force generally by pull-out test machine or universal testing machine on behalf of recording, flatness is difficult to ensure, and test is the wide carbon fiber board sample of 12.5mm, there is very big error in test result, and experiment condition and practice of construction condition difference are very large, because in practice of construction be the whole plate construction of carbon fiber board, even if sample passes does not ftracture when can not ensure that carbon fiber board is constructed, therefore experimental result cogency is not very strong.
Summary of the invention
The utility model, in order to improve experimental accuracy, is filled up the blank of existing special pre-stressed carbon fiber beaverboard anchorage system stretching force testing machine, is provided a kind of pre-stressed carbon fiber beaverboard anchorage system stretching force test unit.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of pre-stressed carbon fiber beaverboard anchorage system stretching force test unit, comprises support body unit, stiff end, stretching end and stretching force applying unit; Described support body unit is provided with fixing feet, and described fixing feet is connected by chemical anchor bolts with ground; Tested ground tackle is connected to described support body unit one end by described stiff end, and the carbon fiber board be connected on tested ground tackle is connected to the described support body unit other end by described stretching end; Described stretching end is provided with a supporting plate; Described stretching force applying unit applies stretching force by described stretching end to carbon fiber board and tested ground tackle.Pulling force applying unit increases applying pulling force gradually and exports in real time, until pre-stressed carbon fiber plate is surrendered owing to exceeding the maximum tensile strength; If carbon fiber board yield strength is qualified, and there is not cracking, the slippage of ground tackle in period, carbon fiber board does not also ftracture or other damage, then illustrate that ground tackle is qualified, carbon fiber board is qualified, the syndeton of ground tackle and carbon fiber board is also safe and reliable, qualified, and total reinforcing pre-stressed carbon fiber beaverboard anchorage system stretching force is qualified.The carbon fiber board be connected on tested ground tackle adopts the carbon fiber board of full width, and as 100mm is wide, experiment condition is close to execution conditions, and flatness easily regulates, and the data therefore obtained are more true and reliable.
As preferably, described support body unit comprises two pieces of panels and is connected to 4 pull bars between two pieces of described panels.Support body unit is used for supporting and fixing whole test unit.
As preferably, described stretching end comprises threaded rod one and frock baffle plate.The stretching end at construction simulation scene, test figure is more reliable.
As preferably, described stiff end comprises threaded rod two and frock baffle plate.The stiff end at construction simulation scene, test figure is more reliable.
As preferably, described stretching force applying unit is Manual hydraulic jack, and hydraulic cylinder is positioned on described supporting plate.
The beneficial effects of the utility model are: because the utility model adopts as above technical scheme, experimental situation and construction environment are substantially identical, and be convenient to regulate flatness, therefore this experimental result accurately, truly, there is ginseng property, ensure the quality safety stability of pre-stressed carbon fiber plate work progress to a great extent.In addition, this testing machine can not only simulate the site operation environment of tested ground tackle, and can obtain the related performance indicators such as tested ground tackle stretching force and pre-stressed carbon fiber plate tensile strength easily.
Except technical matters, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail hereinafter by reference to the accompanying drawings.
