Description
Technical field
The utility model belongs to and the precast concrete field of building industrialization, specially a kind of composite construction wall
Plate.
Background technology
Prefabricated concrete structure as a kind of structure type for meeting industrialized production, have speed of application it is fast,
Labor intensity is low, noise pollution and wet trade is few and the advantages such as product quality is easy to control.Can using the construction of prefabrication and assembly construction
With effectively save resource and the energy, utilization rate of the material in terms of building energy conservation and structural behaviour is realized is improved, reduction scene is applied
The work quantity of labour force, reduce building waste and reduce the harmful effect of Construction on Environment, improve building total quality and performance.Can
See and promote the Green Development that prefabricated concrete structure is advantageously implemented " environmental protection of four section one ", realize energy-conservation and the emission reduction of construction industry
Target.Country proposes 10 years or so time, assembled architecture is accounted for the ratio of new building and reaches 30%；Building industrialization turns into
Current development important topic, it is the developing industry that policy is encouraged and supported.
The precast construction wallboard of technology mainly has precast shear wall plate and precast rib combined wall board at present.They exist with
Lower shortcoming：(1) precast shear wall plate because the severe for being all coagulation local soil type into, unit volume big (severe of concrete is
25kN/m3), transport and hanging belt to prefabricated components come it is difficult, so as to need to reduce the size of prefabricated components, add it is prefabricated
The joint connection in site quantities of component, another aspect construction costs are higher.(2) code JGJ/T275-2013 close rib composite wall board
Overcome precast shear wall plate disadvantages mentioned above, the severe of its unit volume is moderate, and (severe of concrete is 10-17kN/m3), such as
Shown in Fig. 1；But its lateral deformation stiffness reduces a lot, (main function of structural wall is another to be used to support in addition to bearing vertical load
Horizontal force resistant).(3)) Authorization Notice No. 205530681U patents, it is oblique close rib composite wall board, as shown in Fig. 2 oblique is close
Its Lateral resisting ability of rib composite wall board is to be strengthened, but because the drift of the diagonal rib of plate has carrying that is a variety of, causing rib
Ability varies and last Comprehensive Capacity depends on that bearing capacity is minimum not to be destroyed, in addition due also to oblique close rib not
Can be with the vertical equivalent carrying vertical load of side rib (i.e. under vertical uniform load q during one unit vertical deformation of generation, vertically
Element bearing capacity is larger), vertical side rib carries most vertical load, therefore the section of vertical side rib needs to increase
Section, because its rib is using being not vertically and horizontally to set, in vertical Action of Gravity Field, (power is the maximum of building, is also
Existing active force always) under, the horizontal member (beam) at floor where setting and edge member (edge posts) are produced additional
Stress, such as produces that horizontal force component is unfavorable to antidetonation, produces and draws or pressure in horizontal member in interlayer and the diagonal rib junction of post,
Increase horizontal member and edge member stress, make complicatedization；Make the close rib composite wall board cost performance of this design not high.More
Disadvantageously edge member is made to bear more greatly, it is necessary to maximal margin post because diagonal rib sharing capability reduces under vertical uniform load q
Size；So as to add additional work cost (investment).
