Description
Technical field
The invention belongs to technical field of buildings, is related to a kind of precast wall panel, various steel constructions, framework are can be widely applied to
Structural construction etc..
Background technology
From 1958 since first precast concrete wall panel house is built up in Beijing, precast concrete wall panel industrial development
Rapidly.Although full assembled and assembled integral large panel building are built using precast concrete wall panel, can improve construction factory
Change, mechanization degree, reduce situ wet operation, save live recruitment, overcome seasonal effect, shorten the construction cycle, and in advance
Side fascia processed has become one of approach of building industrialization development.But so there is problems with the installation of precast wall panel times：
Side fascia in-site installation mode is not inconsistent with calculation model for design, and Side fascia is installed and adjusts difficulty greatly, and Side fascia is connected heat with main body
Bridge, Side fascia are seeped water with main body connecting portion.
The content of the invention
It is an object of the present invention to provide it is a kind of efficiently, easily precast wall panel and assembly method.The present invention is adopted and is added
Gas concrete and prestressed anchor, ensure its shearing strength while precast wall panel is mitigated；Realized using slidingtype bolt
Three-dimensional is moved, and is drastically increased degree of accuracy, is reduced difficulty of construction, accelerates construction speed and ensure that construction quality.
In order to solve the above problems and realize above-mentioned requirements, the present invention takes following technical solution.
（1）This precast wall panel is provided with anchor pole, threaded anchor pole cap, slidingtype bolt, bolt position-limited box, embedded box, groove living,
Air entrained concrete fills wall body of wall, and mounting post, built-in connection in post, nut bore, nut inside connecting rod reinforce steel disc.
（2）This precast wall panel mainly passes through built-in connection in slidingtype bolt and post and air entrained concrete is filled wall wall
Body is fixed in mounting post.Air entrained concrete filling wall body of wall is passed through anchor pole and threaded anchor pole cap and is integrated with embedded box link.
In post, nut bore and reinforcing steel disc are linked by nut inside connecting rod and are integrated by built-in connection.
（3）This precast wall panel fills wall body of wall using air entrained concrete, and air entrained concrete insulation, heat-proof quality are good（Lead
Hot coefficient:0.11）：Its insulation, heat-proof quality are six times of glass, three times of clay, ten times of normal concrete；It is fire-retardant, resistance to
Fire（Fire resisting in 4 hours）：Air entrained concrete is inorganic matters, will not be burnt, and will not also produce harmful gass, heat conduction system at high temperature
Number is little, and thermophoresis is slow, can effectively resist fire, and protect its structure not receive influence of fire；It is lightweight, high-strength：Density is common mixed
1/4, the 1/3 of clay brick of solidifying soil；Sound absorption, sound insulation value are good, and the air entrained concrete of different-thickness can reduce by 30～50 decibels
Noise；Cubic compressive strength >=4mpa.The present invention adopts air entrained concrete, makes full use of which from heavy and light, intensity height, ductility
The strong advantage of good, shock resistance.
（4）This precast wall panel uses prestressed anchor, improves precast wall panel shear resistance and intensity, and prestressed anchor
Bar causes the globality of precast wall panel to improve, and the connection of embedded box and air entrained concrete filling wall body of wall is more firm.
（5）Pre-installation bolt position-limited box, living groove of the slidingtype bolt in bolt position-limited box in this precast wall panel embedded box
Interior vertical direction movement is adjusted, and precast wall panel can be adjusted in the horizontal direction, realizes three-dimensional adjustment, is reduced pre- to producing
The required precision of system, improves overall accuracy and efficiency of construction.
（6）The corresponding mounting post of this precast wall panel is provided with built-in connection in post, and nut bore will add with slidingtype bolt
Gas Concrete Filled wall body of wall is fixed in mounting post, and nut inside connecting rod and reinforcing steel disc make built-in connection in post firmly put
In mounting post.
（7）Air entrained concrete filling wall body of wall is fixed on installation with slidingtype bolt by nut bore by this precast wall panel
On post, the part deadweight that air entrained concrete fills wall body of wall is transferred to into mounting post, reduces air entrained concrete filling wall body of wall pair
The load of floor, weakens heat bridge effect.
The assembly method of precast wall panel, comprises the following steps：
1）Develop erection sequence figure.Size, quality mounting hanger during lifting first according to precast wall panel, by precast wall panel
Suspender is moved to into wall top after being hung to ground；
2）Surveying setting-out is completed, according to the particular location line of the precast wall panel released, using cushion block special to prefabricated outer
Wallboard carries out absolute altitude levelling；Every block of wallboard is placed（2 ）Group cushion block, cushion block are individually positioned at component length direction 1/4, and are padded
Doorway positions should be avoided in block position；
3）During hoisting prefabricated Side fascia, during lifting, each suspension centre answers uniform force, and lifting preferably use at the uniform velocity, and using it is slow rise, fast liter,
The slow mode of operation put；
4）Precast wall panel bearing diagonal is installed, every piece of precast wall panel is fixed with two bearing diagonals, bearing diagonal is solid by special bolt
It is scheduled on precast wall panel；
5）Adjust slidingtype bolt（3）, realize that perpendicularity is adjusted.With spanner by slidingtype bolt（3）Precession nut bore（10）；
6）The default joint gap on each side of precast wall panel is checked, after completing overall assembly connection, in precast wall panel and peace
Default wide seam between dress post, floor carries out the cementation of fissures process of concrete and completes structurally waterproof.
The present invention has advantages below：
1st, it is economical：Air entrained concrete is light material, conducts oneself with dignity little, can reduce load-carrying members materials；Slidingtype bolt realizes three-dimensional
Adjustment, simplifies construction, shortens the completion time of project, increases profit margin.
2nd, it is convenient：Aerated concrete products size is accurate, lightweight, is readily transported, lifts, and precast wall panel is when mounted
Using dry construction method, and this precast wall panel mounting process is easy, efficient, can effectively improve overall accuracy and quality.
3rd, environmental protection：Under air entrained concrete high temperature and small gas independent in harmful substance, and body of wall will not be discharged in fire
Bubble, makes air entrained concrete have certain impermeability, can prevent the infiltration of gas and water.
