The reinforcing adopting cloth to carry out building structure has convenient and quick construction, and conduct oneself with dignity little, intensity advantages of higher, it is widely used in concrete structure at present, but the application in Autoclaved aerated concrete slabs still lacks to be studied widely.Because steam-pressing aero-concrete belongs to fragile material, its shearing resistance and tensile strength lower, and the resistance to tension of cloth is very high, can make up these shortcomings of steam-pressing aero-concrete.Traditional Autoclaved aerated concrete slabs wall body door or window hole reinforcing mode adopts angle steel or flat steel reinforced, and these reinforcement means can improve the anti-seismic performance of structure, but door and window hole rigidity may be caused excessive, make bight, hole occur crack.
Utility model content:
The purpose of this utility model is the problem of reinforcing for solving steam-aerated concrete plate door and window hole, makes door and window hole can bear larger load, and improves its ductility, increase its anti-seismic performance, reduces crack, door and window hole bight.
For achieving the above object, the utility model adopts following technical scheme: a kind of body of wall assembled with the steam-aerated concrete plate of door and window hole, comprise the connection of steam-aerated concrete plate, body of wall reserves door and window hole, the oblique cloth that the cloth of pasting around hole and bight, hole are pasted.
The assembled of described steam-aerated concrete plate comprises conventional horizontal dress method, erect dress method and anyhow mix assembled method, sheet material is by existing connected mode, as HOOK BOLTS node, built-in fitting node with wave the connected modes such as node and be connected with agent structure, sheet material in assembled, reserved door and window hole.
Described door and window hole, can not reinforce when its size is less than 300mmx300mm, but must take suitable reinforcement means when dimension of opening is greater than this numerical value.
Described cloth comprises carbon cloth, the various different fibrous material such as glass fabric and aryl fiber cloth, and it is stressed single load bearing and bidirectional stress, can choose suitable material category according to its different needs.
Described fiber cloth reinforced door and window hole, is pasted onto the surrounding of door and window hole by the cloth of cutting out, and ensures that cloth is firmly connected with steam-aerated concrete plate, extrudes the bubble between cloth and sheet material.Oblique cloth is pasted in the bight at hole. be used for reinforcing bight, hole, prevent the generation in crack, bight.
Fiber cloth reinforced steam-aerated concrete plate door and window hole described in the utility model, adopt steam-aerated concrete plate to be spliced successively body of wall, aerated concrete panel and agent structure take effective connection.Door and window hole adopts cloth to reinforce, and add the stress performance at door and window hole position, the anti-seismic performance of door and window hole is improved, and overcome traditional angle steel reinforced door and window hole and cause its rigidity excessive, bight, hole easily produces the problem in crack.Cloth adds the ductility at hole, meets the antidetonation target of multi-way prevention.
Accompanying drawing illustrates:
Fig. 1 reinforces for perpendicular dress method Autoclaved aerated concrete slabs window hole and schemes;
Fig. 2 is horizontal dress method Autoclaved aerated concrete slabs window hole reinforcing figure;
Fig. 3 mixes dress method Autoclaved aerated concrete slabs window hole to reinforce figure anyhow;
Fig. 4 is door Autoclaved aerated concrete slabs door opening reinforcing figure.
Specific embodiment party mode:
By the Autoclaved aerated concrete slabs door and window hole reinforcement means shown in Fig. 1-Fig. 4, mainly comprise the body of wall be made up of horizontal and vertical Autoclaved aerated concrete slabs 3 and 4, the door and window hole 5 and 6 of rectangle, the cloth 1 of door and window hole surrounding and play the oblique cloth 2 of reinforcement effect in bight, hole.
Select perpendicular dress method steam-aerated concrete plate reinforcing form to be described in detail below, remaining reinforcing mode can carry out with reference to this kind of method.
Steam-pressing aero-concrete wallboard 3 is effectively connected with agent structure by ripe construction method, carries out the work of row's plate, reserve window hole 5 before assembled.The construction of window hole reinforcing is carried out after completing the erection work of wallboard.Its concrete construction method is as follows:
The first, the process on steam-aerated concrete plate surface: determine the region that will reinforce at window hole surrounding marking pen, to polish flat plate surface with angle grinding machine and blows away the dust on surface with hair-dryer, ensures surface clean, smooth.After surfacing is good with acetone or alcohol surface wipes is clean.
Second, configure and brush special glue: glue curing compound and host proportional arrangement to specifications being become to paste cloth, glue is smeared in the region determined, when smearing glue, too not thick can not be too thin, ensure that glue penetration is in the hole on gas concrete surface, then levelling at colloid surface.
3rd, paste cloth: the colloid surface after levelling pastes the cloth 1 of cutting out in advance, cloth is once pasted around hole 5, the bubble between cloth and body of wall is extruded with scraper plate after stickup, when noting using scraper plate again, to scrape along a direction, cannot scrape back and forth.Whether after cloth and body of wall paste, observing cloth surface has colloid to ooze out, if cloth dry tack free, then and the glue that should configure in right amount at cloth external coating.
The method of attaching of the cloth more than underdrawed and technique, after pasting the cloth 1 of window hole surrounding, need to paste oblique cloth 2 in bight, hole, its concrete bonding method is similar to the bonding method of cloth 1, is not repeating.
