Description
Technical field
The present invention relates to building materials mechanical test equipment technical field, particularly a kind of light prefabricated wall preburied component anti-drawing strength pick-up unit that is feature with Smaller load test.
Background technology
Along with the progress of science and technology and the enhancing of people's environmental consciousness, light prefabricated wall, as granular polystyrene wallboard, aerated concrete wall panel, polyphenyl foam combined wall board, because its light weight and excellent insulation, sound insulation value and inexpensive, in-site installation are convenient to use feature and find favour with.Because the inner structure of this kind of wallboard is loose, setscrew during use, can not be adopted to fixedly mount, for this reason, generally adopt at present arrange on wallboard to after boring a hole with to wearing bolt, to fixedly mount the method be arranged on building frame girder steel wall constructed.Owing to there is keyhole eye and do not allow the metal bolts overhanging end of equating process on the body of wall constructed, the integral heat insulation performance of buildings can be affected, thus need to carry out secondary to whitewash, with plugging bolt hole eye, take the external decoration measure of some covering metal component exposed junctions, cause complicated construction technique, affect construction cost.But, if hardware is reliably pre-buriedly arranged in light prefabricated wall with the form of installing connecting elements, makes that light prefabricated wall can the one-sided outer form be hung on building frame girder steel be assembled is built into complete atresia on outside surface, construction wall without metal residual component, certainly will be conducive to the total quality simplifying construction technology, improve body of wall, the setup cost improving overall operating efficiency and reduction construction wall like this, this is undoubtedly the act that a kind of existing outstanding practicality has again the Kechuang of remarkable economy.But, because the quality of light prefabricated wall own is loose, the load carrying capacity being embedded in installation connecting elements is wherein relatively little, limit resistance to plucking load is approximately only at about 500Kg, and the jack type load-measuring device of withdrawal resistance mostly more than 1 ton that building trade is used at present obviously cannot be competent at.Therefore, a kind of Smaller load pull strength of necessary research and development measurement mechanism, thinks the entering the market of lightweight built-in type prefabricated panel, applies and provide compellent scientific theory foundation, make it to become renewal product worthy of the name.
Summary of the invention
The object of the invention is to overcome the deficiency lacking Smaller load anti-drawing strength testing apparatus in current building materials mechanical test field, provide a kind of and can be used for that test base inner structure is loose, the little light prefabricated wall preburied component anti-drawing strength pick-up unit for feature of the bearing capacity of preburied component.
Light prefabricated wall preburied component anti-drawing strength pick-up unit main body of the present invention is made up of rigid support and metering dynamometry assembly, it is characterized in that described rigid support comprising the quadra being provided with band lower margin holder, be arranged on the sample limit component on quadra and weighing bracket, described metering dynamometry assembly includes the steelyard hook having traction assembling end, by weighing end, the arm beam of steelyard that metering end and the supporting ring being arranged on weighing end and metering end junction are formed, be convenient to adjust the sliding weight of steelyard of counterweight as required and play the weigh-shaft of point action, wherein: described quadra is by left and right side frame, front and back side frame, lower underframe and upper frame are formed, described weighing bracket fixedly continues the front side frame or rear side frame upper end that are arranged on quadra, is provided with the cross bar of holding a concurrent post weigh-shaft above, described sample limit component include be fixedly installed on side frame middle and upper part, left and right horizontal holder card article, be arranged on position, side frame middle and lower part, left and right, the bottom bracket being provided with movable spacing card article and the ceiling molding be arranged in upper frame, be fixedly installed the steelyard hook seat in the some drop hanger holes of band below described weighing end, described metering end is provided with graduated scale.
In the assembled condition, described rigid support is anchored on ground by lower margin holder, the described arm beam of steelyard is held by supporting ring, level is to being vertically limited on weigh-shaft, the hook of selecting as required of described steelyard hook is held in the drop hanger hole of described steelyard hook seat, traction assembling end assembles with the anchor bolt on sample light prefabricated wall and is connected, and described sliding weight of steelyard is movably set on the metering end of the described arm beam of steelyard.
During work, sample light prefabricated wall is spacing by described sample limit component, level clamping or vertical folder are held in described quadra as required, the position in the drop hanger hole of holding, the weight regulating sliding weight of steelyard and the position of mobile sliding weight of steelyard on metering end is hooked by combining adjustment steelyard hook, measure and the anchor bolt tension pull out force nominal strength calculated on sample light prefabricated wall or ultimate strength, thus judging the functional reliability of sample, the light prefabricated wall installing connecting elements for being provided with external hanging type in pre-buried drops into the theoretical foundation data that practical application provides science.
Based on the Light trabs preburied component anti-pulling experimental provision of the present invention of above-mentioned design, due to lighter for Light trabs dead weight, holding load forces to the load of pre-buried setting installation connecting elements wherein when constructing construction wall requires less, and accuracy of detection requires not extra high situation and develops, and device itself is relatively simple for structure, setup cost is not high, but it is rational in infrastructure, easy to use and functional reliability and test data repeatability is strong, there is very strong practicality, not only may be used for professional production and be embedded with the light prefabricated wall factory of installing connecting elements, as universal factory inspection equipment, but also may be used for working-yard, as the verifying attachment checking and accepting or inspect by random samples product quality indicator.What the Light trabs along with pre-buried installation connecting elements constructed external wall superiority constantly appears the accreditation with market suddenly, light prefabricated wall preburied component anti-drawing strength pick-up unit of the present invention also will obtain synchronous approval, and thus market application foreground is wide.
