Description
Technical Field
The utility model relates to an impervious detection area, in particular to a pressurization and shedder for concrete impervious test block.
Background
In the process of quality acceptance of construction projects, structural members below +/-0.000 have anti-permeability requirements, construction units are required to manufacture anti-permeability test blocks according to the requirements to test and evaluate the anti-permeability performance of concrete, and the test of the anti-permeability performance of the concrete is used as an important technical means for evaluating the durability of the concrete and is widely applied to the engineering construction fields such as hydraulic structures, underwater, underground and the like.
The national standard of the people's republic of China, standard of testing methods for long-term performance and durability of ordinary concrete, GB/T50082, stipulates that a spiral pressurizing machine can be adopted as pressurizing equipment for installing a test piece, the pressure of the spiral pressurizing machine needs to ensure that the test piece is pressed into an anti-permeability test mould, and a pressure testing machine is adopted for demoulding after the test is finished.
In general, a laboratory generally uses a compression tester as a pressurizing and demolding device, and when conditions permit, the laboratory also separately purchases a screw pressurizing machine specially used for installation and demolding.
However, the impervious test block for inspection is a truncated cone with a height of 150mm, the self weight of the impervious test block reaches about 9.2kg, and the weight of a metal test mould matched with the impervious test block is added, so that the impervious test block is large in size and heavy in weight, time and labor are wasted when the impervious test block is manually transported from the top to the bottom of a press machine, the test block can be damaged in the transporting process, and the mounting quality of the test block directly influences the final result of the success or failure test of the test.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a pressurization and shedder for impervious test block of concrete, simple structure, convenient operation overcomes the shortcoming that wastes time and energy of carrying from top to bottom when compression testing machine or screw press install and the drawing of patterns to, this structure dead weight is light, with strong points, and work efficiency is high.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a pressurization and shedder for concrete anti-permeability test piece, is including the twice stand of being parallel to each other and perpendicular stator on the bed plate, and the stand top violently is equipped with the top board, and the bed plate forms the recess through the stopper of bilateral symmetry between the stand, and detachable from the middle on the top board is fixed with the jack, and the recess is used for setting up anti-permeability test mould, and anti-permeability test mould one side is equipped with the end of amplification.
Furthermore, the jack is an oil jack.
Furthermore, reinforcing ribs are arranged between the upright posts and the upper pressure plate.
Furthermore, the limiting blocks are fixed with the base plate through bolts.
To sum up, the utility model discloses possess following advantage:
the utility model discloses simple structure, convenient operation overcomes the shortcoming that wastes time and energy of carrying from top to bottom when compression testing machine or screw press install and the drawing of patterns to, this structure dead weight is light, and is with strong points, and work efficiency is high.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
example 1:
a pressurizing and demoulding device for a concrete impermeability test block is shown in figure 1, and comprises a base steel plate 1, an upright post 2, a frame 3, a coring motor 4 and a coring barrel 5.
Specifically, including being parallel to each other and perpendicular stator twice stand 2 on bed plate 1, 2 tops of stand violently are equipped with top board 3, for guaranteeing structural connection intensity between them, reach better pressurization effect, are equipped with stiffening rib 6 between stand 2 and the top board 3.
The base plate 1 forms the recess 12 through the stopper 11 of bilateral symmetry between stand 2, and recess 12 is used for setting up impervious examination mould 5, and is specific, and impervious examination mould 5 one side is equipped with the end of amplification 51.
And the stopper 11 is fixed with 1 bolt of bed plate to, to the impervious mould needs that can't lead to, the stopper can select different width to be fixed with the bed plate, thereby recess 12 size is adjustable, and application scope is big, and the practicality is strong.
Detachable from middle on the top board 3 is fixed with jack 4, and both can be bolted connection, also can be the draw-in groove is fixed, or other card dismantlement connected mode to the jack is oil jack, and market draws materials easily.
In this scheme, bed plate, stand and increased pressure board are drawn materials from angle steel or channel-section steel, adopt welded mode to connect, and the structure sets up succinctly rationally, and the cost of manufacture is low, and manufacturing is simple, saves the fund input, and simultaneously, this device is dismantled and is removed conveniently, and is not harsh to the place demand.
The working mechanism is combined for further explanation, a proper limiting block is selected according to the size of the anti-seepage test die, the size of the groove is determined, and particularly, the groove is slightly larger than one end of the anti-seepage test die with the small diameter.
Before the test, the anti-permeability test die is positively arranged at the groove, the test block to be tested which is subjected to sealing treatment is arranged in the anti-permeability test die, and then the pressure is applied through the jack to press the test block into the anti-permeability test die.
And during demoulding, the test mould with the test block is reversely placed on the groove at the lower part of the bracket, and the jack slowly applies pressure on the upper part of the test block to remove the test block from the test mould.
In conclusion, the whole die pressing and demolding process is simple, the operation is convenient, the dead weight of the whole structure is light, the movement is convenient, and the defect of operation on a pressure testing machine or a spiral pressure machine can be well overcome.
This scheme compares with traditional compression testing machine or the screw press who is used for the installation drawing of patterns specially, can save experimental material time of removing greatly, improves work efficiency.
Furthermore, the device is convenient in material use, simple in processing and manufacturing, capable of saving capital investment, strong in pertinence and good in practical application value in the anti-permeability performance test process.
