Description
Technical field
The present invention relates to construction work detection and authenticate technology field, be specifically related to a kind of anchor for mortar surface layer intensity detection and detection method thereof.
Background technology
Masonry structure is a kind of architecture structure form generally using of China.Along with progress and the expanding economy of science, people are set up defences by earthquake-resistant building and the requirement of security performance improves constantly, and existing old masonry structure building fiduciary level is on the low side, do not meet the requirement of setting up defences of existing earthquake resistant code.When house needs change structure purposes, improves working load, increases usage space, or while not reaching designing requirement because construction quality is inferior, just need structure to carry out reinforcement and strengthening, to ensure that it uses safety, extends tenure of use.
The common reinforcement means of masonry structure building comprises: Enlargement of Section, mesh reinforced cement mortar surface layer method for strengthening, Covered with Angles method, overcoat reinforced concrete wall method, collar tie beam and constructional column are set, set up or expand buttress, wall between windows place sets up reinforced concrete structural column etc.Wherein, mesh reinforced cement mortar surface layer method for strengthening is the comparatively cost-effective method of one.The method is to cracking or the additional bar-mat reinforcement of uncracked body of wall, adopts conventional cement mortar surface layer to reinforce, to improve its bearing capacity, rigidity and shock resistance.Mesh reinforced cement mortar surface layer method for strengthening, because easy construction, cost are low, and does not take space substantially, and in the reinforcing of masonry supporting member or concrete bearing member, application is very general.
In the practice process of mesh reinforced cement mortar surface layer method for strengthening, usually can be because a variety of causes cannot determine whether the strength grade of mortar meets design requirement.But, how consolidation effect is carried out to accurate evaluation and become one of important topic in field of reinforcement, carry out the research to consolidation effect detection technique, find effective, economic detection method and set up corresponding technical regulation and industry standard becomes an extremely urgent job.
In traditional detection technique means, the compressive strength of sand-cement slurry detects also some ripe detection methods, as rebound method, penetration method and shearing method etc.But consider that mortar surface layer intensity has directly reflected consolidation effect, therefore determine that by mortar surface layer being carried out to on-the-spot sampling Detection actual mortar strength also just becomes a kind of very important detection means.But up to the present, in Practical Project, the Site Detection of mortar surface layer compressive strength does not also have special pick-up unit and unified standard.Due to the singularity of mortar surface layer, the detection means of above-mentioned concrete or ordinary mortar compressive strength can not be applied to the Site Detection of surface layer mortar directly and accurately.In engineering reinforcement, the compressive strength of surface layer mortar used is all in M30 or above grade, so the detection means of ordinary mortar compressive strength still can not meet testing requirement.Core drilling method has large, the capacious feature of on-site sampling thickness, it is the method the most accurately of test material compressive strength, but core drilling method sampling thickness is at least 75mm, and in engineering reality, the thickness of mortar surface layer is only 25mm～40mm, cannot meet its application conditions.While adopting rebound method to detect, concrete crushing strength reisilometer Site Detection has the characteristic that influence factor is many, discreteness is large, and the method is inapplicable equally to the detection of mortar surface layer.Therefore, find a kind of practical reinforced cementitious mortar detection method to eliminate hidden dangers in project, guarantee that construction quality has safely very important meaning.
The features such as pulling out method has micro-destructive, and testing process is simple to operate, and detection reparation is afterwards comparatively easy, have been widely used in the detection of concrete crushing strength, and many experts both domestic and external all did the research of similar work, respond well.Consider the similarity of mortar and concrete material performance, researchist has carried out the exploration of pulling out method Site Detection mortar surface layer compressive strength, and has obtained good achievement in research.The method is first chosen measuring point on mortar surface layer, utilizes the method first filling or fill afterwards that anchoring piece is vertically imbedded in mortar surface layer, then with pullout machine, anchoring piece is extracted from mortar surface layer, records peak pullout load.Testing staff, by the linear formula between mortar surface layer withdrawal force and compressive strength, can calculate corresponding mortar surface layer intensity according to the withdrawal force recording.While adopting rear-extraction method to detect reinforcing the intensity of mortar surface layer in Practical Project, first on mortar surface layer, choose measuring point, then perpendicular to metope boring injecting glue, anchoring piece is imbedded in hole, after reaching intensity, with pullout machine, anchoring piece is extracted in colloid, by correlation formula, can calculate corresponding mortar surface layer intensity according to withdrawal force.But in practical operation, anchor adhesive solidifies and reaches intensity and need certain hour, anchoring piece in hole often gravitate is sagging, cannot be completely vertical with vertical metope, cause recording withdrawal force numerical value inaccurate, and then have influence on the accuracy of mortar surface layer intensity detection.
