Abstract
The utility model discloses a partition wall structure for preventing the connection portion from cracking. The partition wall structure for preventing the connection portion from cracking comprises a keel, gypsum boards, an expansion bolt and rock wool, wherein polystyrene foam is arranged on the back face of the keel; the keel is bonded on a wall through the polystyrene foam; the expansion bolt is arranged in the direction perpendicular to the back face of the keel; the expansion bolt penetrates through the keel and the polystyrene foam and is fixedly connected with the wall; the gypsum boards are arranged on the two sides of the keel; the gypsum boards on the two sides are filled with the rock wool and are fixedly connected with the keel through self-tapping screws. The solidified polystyrene foam has the good effects of jointing, bonding, sealing, thermal insulation, sound absorption and the like, and is an environment-friendly and energy-saving building material convenient to use. Firstly, the keel and the wall surface are flexibly connected through the polystyrene foam, so that compressional deformation caused by toughness when the temperature rises is avoided. Then, the polystyrene foam can effectively and firmly bond the wall with the keel, so that bonding force is increased to resist shrinkage deformation caused when the temperature falls.
Description
Technical field
The utility model relates to building decoration technology field, espespecially a kind ofly prevents from joining the curtain wall structure in generation crack, position.
Background technology
For the crack of blockwork or concrete wall and light steel keel gypsum board intersection be always puzzlement this be also puzzlement whole building trade a great problem.Due to two kinds of each self different shrinkage characters and coefficients of expansion of having by oneself of different constructional materialss, air-entrained concrete building block has large, the dry-shrinkage deformed outstanding feature of water absorption rate, in the time that water content of block is greater than 5%, and its dry-shrinkage deformed tending towards stability.In the time that the dry-shrinkage deformed tensile stress of bringing exceedes the adhesion strength between seam, crack just occurs; Or in the time that expanded by heating is out of shape, so contact this position meeting extrusion, produce crack due to two kinds of materials " very stiff and demanding ".Although this crack can not produce and threaten structural safety, is only to affect outward appearance.But be unallowed equally in our fine fitment engineering.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of curtain wall structure in generation crack, position that prevents from joining.
The utility model is a kind of curtain wall structure in generation crack, position that prevents from joining, comprise light steel lightgage steel joist, gypsum plank, expansion bolt, rock wool, the described lightgage steel joist back side arranges foamed glue, lightgage steel joist is bonded on body of wall by foamed glue, the direction vertical with the lightgage steel joist back side arranges expansion bolt, expansion bolt is fixedly connected with foamed glue and with body of wall through lightgage steel joist, lightgage steel joist both sides arrange gypsum plank, fill rock wool in the gypsum plank of both sides, and both sides gypsum plank is fixed by self-tapping screw and keel.
The thickness of described foamed glue is 1cm-2cm.
Gypsum plank inside, both sides arranges several lightgage steel joists, and both sides gypsum plank is fixed by self-tapping screw and lightgage steel joist.
Vertical and the gypsum plank of described self-tapping screw.
Useful technique effect of the present utility model is: the foamed glue after solidifying will have good Tian Feng ﹑ Nian Jie ﹑ Mi Feng ﹑ Ge Re ﹑ sound-absorbing texts, and is that a kind of Huan protects Jie Neng ﹑ constructional materials easy to use.First it makes lightgage steel joist and metope junction for flexibly connecting, and has avoided the appearance of " very stiff and demanding " crimp in the time that temperature raises.Then foamed glue effectively firmly bonds body of wall and lightgage steel joist, the shrinkage strain while increasing the reduction of adhesion stress opposing temperature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of curtain wall structure in generation crack, position that prevents from joining, comprise lightgage steel joist 1, gypsum plank 2, expansion bolt 3, rock wool 4, the described keel back side arranges foamed glue 5, lightgage steel joist is bonded on body of wall 6 by foamed glue, the direction vertical with the lightgage steel joist back side arranges expansion bolt, and expansion bolt is fixedly connected with foamed glue and with body of wall through keel, and lightgage steel joist both sides arrange gypsum plank, in the gypsum plank of both sides, fill rock wool, both sides gypsum plank is fixed by self-tapping screw 7 and keel.The thickness of described foamed glue is 1cm-2cm.Gypsum plank inside, both sides arranges several lightgage steel joists, and both sides gypsum plank is fixed by self-tapping screw and lightgage steel joist.Vertical and the gypsum plank of described self-tapping screw.
When construction, measure unwrapping wire, determine body of wall position according to Design Requirement Drawing, on metope, eject wall bit width control line with ink fountain.By clean body of wall base cleaning, on body of wall, punch, punching, hole dot spacing is 600mm, termination is less than or equal to 50mm.First lightgage steel joist is cleaned out and will on the lightgage steel joist back side, be stamped foamed glue, lightgage steel joist is bonded on body of wall with foamed glue, after foamed glue solidifies, by swollen employing M10 bolt, it is fixed on metope, notes the verticality of lightgage steel joist.Then seal a side layer gypsum plank, rock wool is installed, sealing opposite side gypsum plank, plate seam is processed.
Body of wall intersection is first used special gap filler filleting, then alkali-proof glass fiber mesh, rub flatten non-wrinkled, paste plumpness reach 100%.Puttying, pastes filleting paper tape, to be dried rear with the thick flexible waterproof putty levelling of 3mm, finally on putty, brushes elasticity veneer coating.
