Description
Technical field:
The present invention relates to the structural design of skin entirety and wallboard and corresponding construction techniques correlative technology field, specifically provide the construction techniques of a kind of building with blocking external wall system.
Background technology:
In prior art, traditional brick wall enclosed structure, the enclosed structure of concreting in site and prefabricated panel not system in the process of construction, the construction period is long, complicated operation, and technique effect is limited. Meanwhile, the structure comparison of skin body is single, how to apply based on concrete material; Its technique effect is relatively limited.
Accordingly, it is desirable to obtain the construction techniques that the excellent operability of a kind of technique effect has the building of blocking external wall system better.
Summary of the invention:
It is an object of the invention to provide the construction techniques of the excellent building with blocking external wall system of a kind of technique effect.
The invention provides the construction techniques of a kind of building with blocking external wall system, after the beam of building, post, floor slab construction, carry out the construction of skin plate; It is characterized in that: it uses prefabricated blocking body of wall, it coordinated with the beam of building, post, floor and be installed and fixed into one, adjacent blocking body of wall also constitutes cooperation installation relation each other; And form the complete outside the pale of civilization wall system of continuous print building unit;
The connected mode of blocking body of wall and the beam of building, post, floor one or a combination set of is mounting, is specially hanging point design, and wallboard weight is all carried by upper support structure, and bottom is or/and the left and right sides is provided with auxiliary stopper structure; Connect with inserting mode between adjacent blocking body of wall; Above-mentioned type of attachment collectively forms the connecting structure of flexibility; It is additionally provided with sealing structure between adjacent blocking body of wall;
Prefabricated blocking body of wall meets following requirement:
One, as, inside the keelson of carriage, the body of wall agent structure of the plane materiel composition of core and upper and lower two sides being additionally provided with following structure one or a combination set of: the supporting water power interface unit of building, door, window, support the reinforcement of big board size wallboard;
They are two years old, the frame of blocking body of wall and keelson place are provided perpendicular to fin or the groove in blocking thickness of wall body direction, namely it is specially male frame 51 or female frame 52 as the keelson of the blocking body of wall of carriage, between adjacent two blocking bodies of wall, forms, by means of corresponding male frame 51 and female frame 52, the structure that is connected; For buffer structure and annular seal space 13 (namely annular seal space 13 is arranged is the closing chamber that grafting is constituted that cooperated by male frame 51, female frame 52) between bottom male frame 51 end of male frame 51 and female frame 52 cooperation place and female frame 52; The mating surface between adjacent two blocking bodies of wall on the mating surface of male frame 51 and female frame 52 or/and outside mating surface there also is provided sealing joint strip 11.
The construction techniques of the described building with blocking external wall system, it is characterised in that: state one of requirement in prefabricated unit body of wall process fullness in the epigastrium and abdomen foot:
One, described blocking body of wall is the composite lightweight wall that equal pressure principle seals, and there also is provided sealing joint strip 11 and constituted the multilamellar barrier structure meeting equal pressure principle with the chamber that seals forming 2-6 series connection and then improve the air-tightness of skin body, watertightness, resisting wind press capacity grade on the mating surface of male frame 51 and female frame 52; And the draining air-vent allowing outside draining is set in the metastable annular seal space of air pressure 13 corresponding to each layer of obstruct;
Its two, blocking body of wall is the composite lightweight wall with vertical hair rock wool, and it is specifically configured to: panel 2, core 3, bonding and thermal insulation material layer 5; Wherein: panel 2 specifically adopts the complex cement fibre board of good endurance, core 3 specifically vertical hair rock wool, bonding and thermal insulation material layer 5 specifically inorganic silica gels bond layer; The two sides of core 3 are adhesively fixed with two panels 2 respectively by bonding and thermal insulation material layer 5;
Composite lightweight wall with vertical hair rock wool to carry out bonding operation when making: first taking one piece of panel 2 and within it contact vertical hair rock wool side uniform application inorganic silica gels bond layer, the thickness of inorganic silica gels bond layer and prescription reach 300 ± 30 grams every square metre; After inorganic silica gels bond layer is smeared, direct bonding vertical hair rock wool constitutes the sandwich layer within panel 2, it is desirable to the vertical hair rock wool unit weight 100 ± 10kg/m used3, bonding rear continuous load is loaded in the surface of sandwich layer, and the time is 30 ± 10 minutes, to ensure the adhesive effect of inorganic silica gels and rock wool; An other deck panels part is installed afterwards;
Its three, blocking body of wall is polyurethane closed rock wool composite lightweight wall, and it is specifically constructed as follows: panel 2, core 3, male frame 51, female frame 52, sealing joint strip 11; Wherein: core 3 is polyurethane foams filling block or rock wool specifically; The top panel of blocking body of wall and lower panel are all panels 2, the core 3 specifically rock wool with fire-proof and thermal-insulation ability it is provided with between two-layer panel 2, four sides of the thickness direction of blocking body of wall are provided with the frame and keelson 1 that can fix or be connected in one each other, being filled with polyurethane foams filling block between rock wool and frame within top panel and lower panel, polyurethane foams filling block is by rock wool separate sealed; So stop rock wool and air contact, form better air-tightness and watertightness effect; In order to increase, heat-insulating property, frame and keelson 1 are internal is filled with the polyurethane foams with incubation and thermal insulation function equally;
The cross section specific constructive form of described frame and keelson 1 is one of " C " type, " U " type, " L " type, " one " type or its certain combining form;
Its four, blocking body of wall is the composite lightweight wall with waterproof ventilated membrane, and it is specifically constructed as follows: keelson 1, panel 2, core 3, waterproof ventilated membrane 8 combine; Wherein, waterproof ventilated membrane 8 is placed between keelson 1 and core 3, and isolation has been fallen core 3 and contacted with the direct of keelson 1; During use, when extraneous rain leaks into keelson 1 place, water can spread along keelson 1 to plate interiors, after water runs into waterproof ventilated membrane 8, waterproof ventilated membrane 8 can well play the effect stoping water to spread to plate interiors, and then effectively preventing internal core 3 to contact with the direct of water, it is ensured that functional being not subjected to of internal core 3 is damaged, thus ensure that the overall performance of composite lightweight wall is unaffected;
Its five, blocking body of wall is the composite lightweight wall with window, and it is specifically constructed as follows: panel 2, core 3, keelson 1, inorganic exterior window trim 6; Wherein: panel 2 is arranged on two sides of core 3, keelson 1 is arranged on the side in whole thickness of wall body direction, and the inorganic exterior window trim 6 for installing window 7 is arranged in inside and outside body of wall inside and connection body of wall;
Wherein: inorganic exterior window trim 6 is specifically made up of indoor exterior window trim 61, outdoor exterior window trim 62; Indoor exterior window trim 61 be quadrilateral frame shelf structure, its be arranged in indoor side and the side, outdoor of window 7 with outdoor exterior window trim 62 common combination; Band batch water exterior window trim 63 fixed and arranged is integrally fixed in the bottom of outdoor exterior window trim 62 or with outdoor exterior window trim 62 bottom;
