Description
Technical field
The utility model relates to a kind of fixture for tensile bond strength detection experiment, for building materials detection field.
Background technology
At present, in building decoration and Energy Conservation Project in Construction, need ornament materials, insulation material to be bonded to an entirety, as boundary mortar, adhesive mortar, decorative paint etc. by the binding material such as cementing agent, adhesive mortar and building substrate.Tensile bond strength reflection material binding ability is strong and weak, is the important indicator passing judgment on binding material performance quality.The national standard of the Related product such as GB/T 25181-2010 " premixing mortar ", GB/T 20473-2006 " thermal insulation mortar ", JG/T 24-2000 " SAND SLURRY SYNTHETIC EMULSION ARCHITECTURAL COATINGS ", JG 149-2003 " expansion joints bellows external thermal insulation system ", DB33/T 1054-2008 " inorganic light-weight aggregate thermal insulation mortar and systems technology code ", industry standard and provincial standard all specify this index, and propose to explicitly call for the tensile bond strength after portioned product immersion, after freezing and thawing test.
According to various criterion, tensile bond strength detection method is also not quite similar, in most standard, tensile bond strength detection method is all with reference to GB/T 16777-2008 " Test methods for building waterproof coatings ", regulation in JGJ/T 70-2009 " building mortar basic performance tests method standard (attached provision explanation) ", or formulate test method and the method described in above two standards similar, being about to customize according to master gauge the sample got ready is coated on the cement bonded sand lumps of 70mm × 70mm × 20mm, coated area is 40mm × 40mm, after by sample according to standard regulation carry out maintenance, after curing period, arrives, again by high-strength adhesives such as specimen surface and upper chucking surface coating epoxy resin, then upper fixture aligned position is placed on sample, continue maintenance 24h.First tensile bond strength fixture is installed on testing machine during test, then by test specimen as in fixture, then according to the rules speed imposed load until test specimen destroy.When test specimen destroys, load is the tensile bond strength of sample divided by sample extension area.
In test, when sample being coated in cement bonded sand lumps surface, easily cause specimen surface out-of-flatness, and be rigidly connected due to cupping machine and upper fixture, cause in drawing process, mortar block upper surface can not contact completely with lower clamp, so that has a strong impact on the generation of test findings accuracy.In addition, due to high-strength adhesives such as upper chucking surface coating epoxy resin, need through pyroprocessing so that clean surface uses for continuation after test, but in high-temperature process, fixture thread oxidation is very easily caused to come off, cause fixture in follow-up use, assemble difficulty, shorten fixture serviceable life, improve testing cost.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the utility model provide a kind of easy to process, structure is simple, dismounting is simple and easy, can reuse, test fixture with low cost.
It is that adopted following technical proposals realizes: a kind of fixture for tensile bond strength detection experiment that the utility model solves its technical matters, be made up of upper fixture (1), lower clamp (2), abutment ring (3) and chain type clamping bar (4), it is characterized in that, described upper fixture (1) top is provided with threaded hole (5), abutment ring (3) bottom is provided with screw rod (8), can be threaded connection with upper fixture (1); Described chain type clamping bar (4) top is provided with clamping bar (9), and bottom is provided with suspension hook (10); Described lower clamp (2) is made up of draw-in groove (6) and lower clamping bar (7), and lower clamping bar (7) is arranged on draw-in groove (6) bottom center position, with draw-in groove (6) plane perpendicular.
Further improvement of the utility model is, realizes chain type flexibly connect by the suspension hook of chain type clamping bar and abutment ring.
Further improvement of the utility model is also, abutment ring and upper fixture are threaded connection.
The utility model in use, chain type clamping bar, lower clamp is separately fixed on cupping machine, bonds after upper fixture and abutment ring being threaded with sample, after by the suspension hook of chain type clamping bar lower end through abutment ring, and the cement bonded sand lumps of sample to be placed in lower clamp draw-in groove.After test, abutment ring and upper fixture are together carried out pyroprocessing.
The utility model with other for tensile bond strength detection experiment fixture compared with, there is following significant technical advantage and feature:
1, during test, be connected with cupping machine because upper fixture is flexibly connected by chain type, even if sample surfaces out-of-flatness, cement bonded sand lumps upper surface still can contact with draw-in groove lower surface completely, avoid sample stressed cracking in advance, guarantee testing result accuracy and stability.
2, assembling, convenient disassembly, upper fixture and abutment ring together take off from suspension hook after detecting by individual sample, shorten sample replacing construction, improve test efficiency.
3, after test, upper fixture and abutment ring are together carried out pyroprocessing, avoids screw thread because of high temperature injury, raising fixture serviceable life.
