Technical field

This utility model is related to testing equipment field and in particular to a kind of decorative mortar tensile bond strength test mould Tool.

Background technology

Decorative mortar is the general designation of the mortar being applied to building or building element surface, according to the difference of function, can be by Decorative mortar is divided into common decorative mortar, decoration mortar and has the decorative mortar of some specific functions (as waterproof mortar, thermal insulation Mortar, sound-absorbing mortar and acid resisting mortar etc.).On the one hand decorative mortar requires possess good workability, easily smears and uniformly puts down Whole thin layer, is easy to construct, on the other hand also should have higher cohesion, screed should be able to cohere firmly with bottom surface, for a long time not Cause cracking or come off.In addition, decorative mortar is in wet environment or is easily subject to external force site of action (as ground and dado etc.), should have There are higher resistance to water and intensity.

According to the requirement of working standard jg149-2003 " expansion joints bellows external thermal insulation system ", decorative mortar Tensile bond intensity should be measured by 5.10 in jg/t3049-1998, particular location as depicted in figs. 1 and 2, this mensure side In method, every group of test specimen is formed by six pieces of cement bonded sand lumps and six cement mortar or expansion polyphenyl plate bonding, prepares survey respectively former strong Degree and each one group of test specimen surveying water-fast tensile bond intensity.Existing mould is mostly absolute construction, once can only molding one , when carrying out decorative mortar tensile bond strength test, there is carrying trouble, put confusion, be also not easy to criticize in test block Amount stretching.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems in the prior art, provides a kind of decorative mortar stretching Adhesive strength test mould, is easy to carrying, puts and batch stretching.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is to be achieved through the following technical solutions:

A kind of decorative mortar tensile bond strength test die, including die ontology, described die ontology offers 12 forming tank, described forming tank runs through the both ends of the surface of die ontology, and the thickness of described die ontology is 10mm, described forming tank Specification be 40mm × 40mm × 10mm.

Further, the lower section of described die ontology is provided with on-gauge plate, is coated between described on-gauge plate and die ontology Adhesive.

Further, described on-gauge plate be by apparent density for 18kg/m3 and by specify into qualified expansion after ageing Styrofoam, expansion polyphenyl plate thickness is 20mm.

Further, described Adhesive thickness is 3mm.

Further, 12 described forming tank are arranged by 2 × 6 or 3 × 4 array way.

The beneficial effects of the utility model are:

The mould that this utility model provides is integral type, can be with two groups needed for disposal molding tensile bond strength test Test specimen, meets the requirement of working standard jg149-2003 " expansion joints bellows external thermal insulation system ", mould carrying, pendulum Put conveniently, in addition after molding, test specimen also allows for stretching in batches, realizes the raising of detection efficiency.

Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
