Description
Technical field
The present invention relates to building material quality detection technique fields, and in particular to a kind of impact echo detection wallboard splicing seams quality
Method.
Background technology
With greatly developing for national assembled architecture, the lightweight wall plate utilization rate as building interior partition wall gradually carries
It rises;The form of construction work of wallboard is construction site splicing at present, and the quality testing for being currently directed to wallboard concentrates on product certainly
Body and scene splicing dimensional discrepancy etc., only have the quality testing of wallboard splicing seams"Building light-weight batten partition wall technology is advised
Journey"(JGJ/T157-2014) " the butt seam planted agent between plate and plate fills up, fills real binding material, plate stitch gap specified in
It should rub and squeeze tightly, it is real that the binding material being extruded should strike off hook ";"Decoration construction inspection of quality specification"
(GB50210-2001) " partition board must firmly install, and detection method is specified in:Observation, hand pulls inspection " etc. qualitative retouch
Predicate sentence has no the support of specific detection method, can not precise and high efficiency judgement wallboard splicing seams quality.
If grouting quality is there are problem in wallboard splicing seams, there are gaps for splicing seams, and partition wall will be caused crack occur, cause
Partition wall energy-efficient performance is set to decline, it is serious to influence building safety performance.Therefore the quality testing of wallboard splicing seams should also be drawn
It rises and payes attention to.
Invention content
The purpose of the invention is to avoid in wallboard splicing seams grouting quality, there are problems, and a kind of impact proposed is returned
The method that wave detects wallboard splicing seams quality.
To achieve the goals above, present invention employs following technical solutions:
The method of the impact echo detection wallboard splicing seams quality of the present invention, includes the following steps:
1) wallboard information is verified;
2) measuring point quantity is determined according to testing goal and region;
3) device parameter is set, carries out impact echo detection in wallboard solid position, determines wallboard impact echo velocity of wave;
4) impact echo detection is carried out in splicing seams outer surface, determines wallboard splicing seams position impact echo velocity of wave;
5) image formed according to detection data judges splicing seams quality suspicious region;
6) cutting verification is carried out to suspicious region, confirms splicing seams quality.
Wherein, wallboard information described in step 1) includes:(1) apparent size:Tongue and groove size, plate thickness;(2) wallboard is
No is cored slab, hollow hole number, size and position;(3) wallboard raw material types;(4) splicing seams binding material type.
Utstanding substantial characteristics and significant improvement of the present invention are:The present invention proposes wallboard splicing seams quality
Detection method will be converted into quantitative detection about the quality testing of wallboard splicing seams in current standard by descriptive qualitative sentence,
It can judge wallboard splicing seams quality by experimental data, be conducive to the precision and efficiency that improve wallboard detection, promote building knot
Structure security performance.
Description of the drawings
Fig. 1 is that Impact echo detects gypsum hollow lath result images;
Fig. 2 is the panel structure schematic diagram to be measured of the present invention;
Fig. 3 is that schematic diagram is arranged in the test point of the present invention.
Reference sign:1- models, 2- splicing seams, 3- binding materials, 4- hollow areas.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples, but not as any limitation of the invention.
It please refers to Fig.1 and Fig. 2:The method of the impact echo detection wallboard splicing seams quality of the present invention includes the following steps:
1) information of wallboard model 1 is verified, it is main including 1. apparent size:Tongue and groove size, plate thickness;2. whether wallboard
For cored slab, hollow hole number, hollow area 4, size and position;3. 3 type of binding material of splicing seams 2.
2) measuring point quantity is determined according to testing goal and region.
3) device parameter is set, carries out impact echo detection in wallboard solid position, determines wallboard impact echo velocity of wave.
4) impact echo detection is carried out in 2 outer surface of splicing seams, determines 2 position impact echo velocity of wave of wallboard splicing seams.
5) image formed according to detection data judges splicing seams quality suspicious region.
6) cutting verification is carried out to suspicious region, confirms splicing seams quality.
Embodiment:
1) verifying 1 information of wallboard model is:1. gypsum hollow lath, length 3000mm, width 600mm, thickness 120mm,
Tongue and groove size 150mm;2. wallboard is cored slab, totally 5 holes, are uniformly distributed, and diameter is 60mm;3. the bonding material of splicing seams 2
Material 3 is special high strength gypsum powder.
2) it is 36 tentatively to choose impact echo measuring point quantity, total VI row, each column 6.
3) device parameter is set, is detected according to step 3), step 4).
4) detection image, the result is shown in Figure 1 according to testing result, are formed.
5) display area in compares figure, the 1st, which arranges the 2nd measuring point, arranges the 3rd measuring point to the 1st, the 3rd arranges the 1st measuring point and arrange the 5th to the 3rd
Measuring point is considered as quality suspicious region there are the relatively low problem of velocity of wave.
6) suspicious region is dug, confirmed, the Ith is classified as gypsum hollow lath solid area, and there are bubbles;Ш
Wallboard splicing seams 2 are classified as, there are binding materials not to fill phenomenon at middle part.
The specific application example of the above only present invention, the present invention also has other embodiments, all to use equivalent replacement
Or the technical solution that equivalent transformation is formed, it all falls within protection domain of the presently claimed invention.
