The invention discloses a light prefabricated wallboard unit for partition. The light prefabricated wallboard unit is a flat cubic prefabricated part with two surfaces and a plurality of side faces. The flat cubic prefabricated part is composed of a prefabricated wallboard and edge parts, wherein the edge parts are arranged on at least one side of the prefabricated wallboard. The prefabricated wallboard is made of light building materials. At least one side face of the prefabricated part is provided with connecting parts. According to the light prefabricated wallboard unit for partition, combination of a building partition function and a structure function can be achieved; the effect that a whole partition wall is composed of one prefabricated unit with the permission of conveying and hoisting can be achieved, so that splicing of the construction site wallboards is reduced, the phenomenon that splicing joints crack is avoided, assembling efficiency is improved, and the large economical feasible light prefabricated wallboard is achieved.
Description
Technical field
The invention belongs to architecture production field, specially one kind separate uses light prefabricated wall unit.
Background technology
Because assembled architecture meets the mode of production of environmental protection and energy saving, national layer sends suits measures to local conditions to develop assembled coagulation
The assembled architectures such as soil structure, steel construction and modern wood structure, strive, with 10 years or so time, making assembled architecture account for newly-built building
The ratio built reaches 30%.
At present the prefabricated wallboard species of technology has the building wall board and bearing load and external force for separating and enclosing effect
The structural wall board (such as seismic structural wall, earthquake resistant wall, shear wall, close rib composite construction board) of effect;Next to that mutually fitting with current a large amount of cast-in-place structurals
The wallboard answered, the yardstick per block are less, connect into monolithic architecture partition wall by scene splicing.Secondly this wallboard connects this wallboard
Easily ftracture at seam, be also performed to site operation, affect efficiency of assembling;Promote assembling building, it is necessary to control prefabricated components
Weight, control cost, and the tensile strength of precast light wall board material is relatively low, to realize that large size prefabricated component brings certain difficulty
Degree.
The content of the invention
It is an object of the invention to provide a kind of cut-off uses light prefabricated wall unit, it realizes building partition function and structure
Function phase is combined, and can realize that in the case of transport and lifting are allowed, a whole partition wall is one piece of prefabricated unit, reduces building site
The splicing of wallboard, the probability for avoiding splicing gaping of joints, improve efficiency of assembling, realize large scale and economically viable precast light
Wallboard.
For achieving the above object, the present invention provides a kind of cut-off of tool and uses light prefabricated wall unit, and it is with two tables
Face and the flat cube prefabricated components of multiple sides, described flat cube prefabricated components are by prefabricated panel and are arranged on
The edge member of prefabricated panel wherein at least one side is constituted;Prefabricated panel is made up of light building material, the prefabricated structure
At least one side of part is provided with connecting elements.
As a further improvement on the present invention, the edge member is armored concrete or fiber concrete or steel beam column.
As a further improvement on the present invention, described light building material is granular polystyrene concrete or air entrained concrete
Or foam concrete or expanded perlite granule concrete.
As a further improvement on the present invention, described prefabricated panel is furnished with tension thing.
Used as the further improvement of the present invention, tension thing described in described tension thing is the arrangement of reinforcement or edge of edge member
Component itself.
Used as the further improvement of the present invention, described tension thing is bamboo product or reinforcing bar or steel beam column or chemical industry synthesis
One of thing or combinations thereof.
Used as the further improvement of the present invention, described bamboo product is the bamboo or bamboo chip or bamboo weaving fabric of minor diameter.
Used as the further improvement of the present invention, described chemical industry synthesis thing is plastic strip or GSZ.
As a further improvement on the present invention, described connecting elements is the embedded bar or edge member of prefabricated panel
Outer extensions are constituted.
Compared with prior art, a kind of of the invention cut-off light prefabricated wall unit has the beneficial effect that:
(1) cut-off light prefabricated wall unit of the invention, subtracts than the wallboard quantity of all assembling Building technologies at present
It is few, in the case of transport and lifting are allowed, a whole partition wall can be realized for one piece of prefabricated unit, the spelling of reduction building site wallboard
Connect, avoid splicing the probability of gaping of joints, mounting structure quantity greatly reduced, improved efficiency of assembling.
(2) cut-off light prefabricated wall unit of the invention, due to the edge member in edge setting structure function,
Edge member makes edge member become the part of major structure of construction in combination with the agent structure of building, to reach more
Economic and connection is more firm, assemble more flexible;It is pre- respectively with construction component that prior art assembling building is structural elements
System, the present invention is that the two is combined;This is the innovation of assembled architecture.
(3) cut-off light prefabricated wall unit of the invention, its building partition funtion part constituted using light material,
And pass through to arrange edge member, increase prefabricated panel element stiffness, make prefabricated panel realize integral prefabricated and edge member
From decoupling out in the structure needed for building itself, so as to realize economic maximization, this is prefabricated components unit of the present invention
Innovative significance.
(4) cut-off light prefabricated wall unit of the invention, improves the tension bar with tension thing or tension in body of wall
Grid, it is passed through the mechanical property that light material is solved from the appropriate tension bar of tensile strength or grid, realizes whole metope
For an integral prefabricated unit;The interior material with skeleton or tension bar or tension grid of prefabricated panel body of wall material combined with it
Material mechanical property matching, this is that a kind of application for making material mechanical performance obtain maximum performance (adopts reinforcing bar due to light material
Encapsulation and intensity it is very low, the intensity of reinforcing bar can not be played), with good economy.
(5) cut-off light prefabricated wall unit of the invention, the bamboo product in advantageous embodiment using string is made
For tension thing when, environmental protection concept is realized to greatest extent;As building tension material, our ancestors use already bamboo, and bamboo is produced
Product are reachable century-old in the service life of cement mortar or the building element interior sealing of lime mortar material;Bamboo is quickly become a useful person
Plant, the intensity of bamboo fiber also meets lifting requirements and just matches with low intensive Light trabses main material, it is to avoid ore deposit
The energy resource consumption of thing rapidoprint and waste gas and dust emission problem are real natural environment-friendly building materials and drive farmer richness;
This bamboo fiber light prefabricated wall is that report is not seen in the whole nation.
