Abstract
The invention discloses a kind of new steel structure thicker fireproof coating construction technologies, include the following steps：1) steel structure surface dust or other sundries are removed first, then in steel structure surface spraying or the special primer of roller coating fireproof coating；2) it after special primer parches, is bonded in above special primer using adhesive special；3) adhesive special bond after the completion of, then with adhesive mortar hang an acid and alkali-resistance glass fiber reticular cloth；4) track bolt, threaded portion are blocked with fireproof coating and smoothed out；5) live scaffold is removed, and hygienic cleaning terminates.The invention belongs to construction engineering technical field, which can ensure the order at scene, can also effectively improve the quality of application.
Description
Technical field
The invention belongs to construction engineering technical field, in particular to a kind of new steel structure thicker fireproof coating construction works
Skill.
Background technology
At present when fireproof coating application, since coating process is lack of standardization, the of low quality of application is caused, application
When thickness differ, while flatness and negative and positive angle can not reach ideal effect, and perception is poor, scene when causing application
Complete confusion, or even a large amount of wastes of raw material are caused, so a kind of coating process of fireproof coating is needed, to improve application effect
Fruit promotes coating quality.
The most 3-5 of project under construction just will appear hollowing, obscission at present, and normally can guarantee 10 years using this product
Be not in that above-mentioned phenomenon occurs above.
Invention content
To solve above-mentioned existing problem, the object of the present invention is to provide a kind of new steel structure thicker fireproof coating construction works
Skill, the coating process specification can ensure the order at scene, can also effectively improve the quality of application.
The technical solution adopted by the present invention is as follows：A kind of new steel structure thicker fireproof coating construction technology, including it is as follows
Step：
1) steel structure surface dust or other sundries are removed first, then in steel structure surface spraying or roller coating fireproof coating
Special primer；
2) it after special primer parches, is bonded in above special primer using adhesive special；
3) adhesive special bond after the completion of, then with adhesive mortar hang an acid and alkali-resistance glass fiber reticular cloth；
4) track bolt, threaded portion are blocked with fireproof coating and smoothed out；
5) live scaffold is removed, and hygienic cleaning terminates.
Further, the special primer is milky primer, solid-weight content 54-55%, pH value 4.0-
6.0, viscosity 500-1000MPaa., weight ethylene content are 15-16%.
Further, mass area ratio >=160g/m of the acid and alkali-resistance glass fiber reticular cloth2, tension failure strength >=
1200N/50mm, acid and alkali-resistance tension failure strength retention >=75%, elongation at break≤4%, mesh centre-to-centre spacing 4-6mm, oxygen
Change zirconium weight content is 13.7-15.3%, and titania weight content is 5.5-6.5%.
Further, the adhesive mortar and cement mortar tensile bond strength >=0.60MPa, adhesive mortar and composite wood
Expect thermal insulation board tensile bond strength >=0.10MPa.
The present invention is obtained and is had the beneficial effect that using the above scheme：New steel structure thicker fireproof coating construction work of the present invention
Skill is developed by the fireproof coating construction experience of inventor for many years is summarized, and this programme is the former material by existing fireproof coating
Material passes through machine and the construction technology that is designed the fire resistance period of respective item according to live drawing.This programme is easily constructed, often
Corresponding thickness cannot all be accomplished according to design requirement by advising existing fireproof coating corner and big face in construction, and use this programme
The generation of problems can effectively be prevented.Sense organ is good after this programme construction, all less beautiful after conventional existing fireproof coating construction,
Negative and positive angular position will appear distortion phenomenon, and big surface evenness is poor, and can effectively be solved the above problems using this programme.This programme is
It is formed according to the steel construction size at scene is customized, under normal circumstances, thickness is customized, thickness according to the requirement of drawing fire resistance period
Generally 1-2.5 centimeters, length and width is generally 30 centimeters, and width also can be depending on the width of live Construction of Steel Structure face.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Embodiment, this programme new steel structure thicker fireproof coating construction technology, includes the following steps：
1) steel structure surface dust or other sundries are removed first, then in steel structure surface spraying or roller coating fireproof coating
Special primer；
2) it after special primer parches, is bonded in above special primer using adhesive special；
3) adhesive special bond after the completion of, then with adhesive mortar hang an acid and alkali-resistance glass fiber reticular cloth；
4) track bolt, threaded portion are blocked with fireproof coating and smoothed out；
5) live scaffold is removed, and hygienic cleaning terminates.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
