Abstract
The utility model provides building field with a loading tester for structural member with force-transfer board which is used for measuring the mechanical property of members. At present, foreign somewhat advanced loading testers adopt inflating capsule pressurization, but can only carry out uniform load experiments and has small universality. The utility model is only added a flexible force-transfer board which is beat and pressed with the air inflating cylinder of a bicycle, and can simultaneously carry out the experiments of uniform load and concentrated load to a beam board member. Because the members within a certain of range of sizes can be tested no need of replacing capsules, the utility model has the advantages of big universality, simple operation, precise measurement, safety and few investments. The loading tester for structural member with force-transfer board is particularly suitable for small-and-medium-size production factories.
Description
The utility model is a kind of improved bearing test machine, it is building element force transmitting board bearing test machine, the testing machine that belongs to the mechanical property that is used for measuring structural elements in the building field is particularly suitable for measuring breaking resistance, rigidity and the breakdown strength of medium and small shaping standard member.
At present, advanced both at home and abroad bearing test device is introduced " using pressurized air to carry out the device of plate test " literary composition with Soviet Union's " concrete and reinforced concrete " 1980 the 5th phases of magazine and is the example (see figure 4).Its device is fixed on the bracing frame (17) for pernetti (14), and the gap between breadboard (15) and the support plate is h=5～10 centimetre.Capsule (16) is to be made by thick 2 millimeters even matter rubber, is surrounded by the fabric protection outward.Capsule is placed between support plate and the breadboard with horizontality.The capsule two ends are than the wide 0.8h of breadboard, and ability warranty test plate is stressed evenly like this, and test findings is correct.Be equal to or less than the breadboard size as capsule size, it is stressed less than the centre breadboard both sides then to occur, can not realize uniform stressed.Cross size as capsule size greater than breadboard, then breadboard under external force, capsule two ends pressurising and the outstanding semicircle that forms surrounds the breadboard dual-side.Because the gas pressure in the semicircle capsule make it to have produced additional side pressure, thereby breadboard is in triaxial stress state in the breadboard dual-side, does not meet the test condition of evenly load.Find out thus, when the member of different size is carried out the mechanics bearing test, need mix the capsule of different size and test.This device versatility is very poor, and because breadboard is positioned at the capsule below, will be in the process of the test from following observation sheet material crack developing situation, very inconvenience, and also dangerous.Main is can only carry out the evenly load test to member with this sampling device, can not carry out the load test.The external at present hydraulic jack that adopts carries out the load test, and an oil pump is controlled the loading of several hydraulic jacks simultaneously.Lifting jack is difficult to reach synchronous working under the small load effect, the requirement on machining accuracy of lifting jack is higher in addition, otherwise can leakage of oil.Domestic more do not have desirable and unified method and type available.
The purpose of this utility model provides a kind of bearing test machine, can be simultaneously on this testing machine the member in the certain size scope be carried out the evenly load that conforms to actual forced status and the test of load.
Task of the present utility model is finished as follows: pressurising capsule (5) is placed on and supports on the supporting plate (6), place a mobilizable flexible force transmission plate (4) above the pressurising capsule (5), the width of flexible force transmission plate (4) is greater than half of pressurising capsule (5) transversal section girth.Member (2) places on the flexible force transmission plate (4), and it is movable laying an end in member (2) top then, and the other end is fixing bearing (1).According to the distance of the width adjusting active side clamping plate (7) of member (2), and be fixed on and support on the supporting plate (6).Pressurising capsule (5) is connected pressure source, open the pressure source pressurising, whole member (2) just is under the evenly load effect to be tested.As carrying out the load test, the stressed position according to member (2) requires is placed on annex (12) or (13) on flexible force transmission plate (4) or the corresponding position of pressurising capsule (5), and bearing test is concentrated in the cut-in pressure source.
The flexible force transmission plate simple structure that the utility model increased, easy to operate.This testing machine can be used for testing laboratory, is more suitable for factory and is used for checking product, as long as operating personnel start air compressor machine and air valve, even can finish three mechanical property tests of member with bicycle pump.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the building element force transmitting board bearing test machine sectional view that the utility model proposes.
Fig. 2 is the organigram of flexible force transmission plate.
Fig. 3 is the organigram of annex.
Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2 and Fig. 3 according to concrete device of the present utility model.
On this testing machine, be of a size of the beam test of long 4200 millimeters, wide 70 millimeters, high 170 millimeters beams of concrete (2), one slat gum capsule (5) is placed on the iron support supporting plate (6), and rubber bag tank (5) one sides are near the smooth vertical fixation side clamping plate (3) of angle steel system.Flexible force transmission plate (4) is placed on the rubber bag tank (5).Flexible force transmission plate (4) is to be pierced in the hole of wooden power transmission plate (10) and rubber washer (11) with steel tendon connecting band (9) by some blocks of wooden power transmission plates (10), conspires to create a flexible force transmission plate (4).Ball (8) is equipped with at flexible force transmission plate (10) both ends, can reduce friction like this with two side clamping plate, curved hand-pulled noodles with beam is placed on the flexible force transmission plate (4) towards people's direction of visual lines then, width according to beam will be regulated in place fixing with the straight smooth active side clamping plate (7) of angle steel system, make active side clamping plate (7) perpendicular to supporting supporting plate (6).It is movable fixing an end on beam, and the other end is fixing bearing (1).After the installation of whole test device is ready rubber bag tank (5) and bicycle pump are connected, adopted and manually inflate, whole beam just bears beam test under the uniform load effect.And can observe the crack developing situation at the curved hand-pulled noodles of beam, realize safe operation.
This machine can adopt mercury gage, measures the loading reading, the accuracy height, and metering is correct. This machine versatility is big, can satisfy the beam test requirement of the interior beam of certain size scope, plate, post member.
