Abstract
The present invention relates to a kind of novel combination type floor and its construction methods.Its structure includes CLT plates, concrete slab and tapping screw, it is spaced apart on the CLT plates and is equipped with several baltimore grooves, the tail portion of the tapping screw is fixed in baltimore groove, and the head of tapping screw is exposed outside CLT plates, and the concrete slab is cast on CLT plates and tapping screw.By arranging baltimore groove and tapping screw in CLT plates and concrete slab interface, CLT plates and concrete slab is set to reach collective effect, the rigidity and bearing capacity of the wooden superstructure can be improved, promote vibration isolation and the sound insulation property of the wooden superstructure, and the fire resistance of the wooden superstructure is improved, for timber structure a kind of settling mode of floor is provided to more high-rise development.
Description
Technical field
The present invention relates to a kind of novel combination type floor and its construction methods, in particular to a kind of orthogonal laminated wood
(CLT) with floor and construction method made of Combined concrete, belong to technical field of civil engineering.
Background technology
Orthogonal laminated wood (CLT) most uses in Europe as construction material earlier than the 1990s, is a kind of by 3 to 9
Layer solid sawn lumber or structure composite plank orthogonal systems base, rectangle, straight line, flat sheet shape made of structural adhesive is suppressed
The engineered wood plate product of formula.Due to using assembly technique, CLT planks that can make full use of small dimension sawn timber, economy and size
Stability is preferable.Since CLT solves the floor height limitation of timber buildings, it can be used for building the even high-rise people in low, middle level
With house and non-civil buildings, it is known as being construction industry " second of the Renaissance ".At present China it is honest push it is dynamic modern more
The development of layer timber structure, orthogonal laminated wood (CLT) shear wall system are one of the suitable structures system of the more high-rise timber structures in China.
CLT planks are usually directly used as wallboard or floor by the timber structure of the prior art, pass through bolt, tapping screw etc.
Connector constitutes entire CLT structural systems.When CLT planks are used as floor, since its rigidity is smaller, usually by normal when design
Ultimate service state controls；And CLT floors vibration isolation and sound insulation property it is weaker, easily influence normal use comfort level, this is also
Hinder one of the factor of more high-rise timber buildings development.In addition, floor is the key that flame is prevented to spread between the layers,
CLT planks are as a kind of combustible material, it will increase the fire load density of building.For improve the rigidity of CLT floors, vibration isolation and
Sound insulation property and fire resistance need to invent a kind of New Floor Slab, and the popularization and application for more high-rise timber structures provide a kind of floor
Settling mode.
Invention content
Technical problem to be solved by the present invention lies in a kind of novel combination type floor is provided, how high can be applied to
Layer, and existing deficiency when CLT planks being overcome to be used as floor.
To solve the above-mentioned problems, the technical solution adopted by the present invention is as follows：
A kind of novel combination type floor, it includes CLT plates, concrete slab and tapping screw,
It is spaced apart on the CLT plates and is equipped with several baltimore grooves, the tail portion of the tapping screw is fixed in baltimore groove, self tapping
The head of screw is exposed outside CLT plates, and the concrete slab is cast on CLT plates and tapping screw.
Further, the spacing between adjacent baltimore groove is preferably 300mm~700mm.
Further, the baltimore groove along plate across equidistant or non-be equally spaced.
Further, preferably, the specification of the tapping screw is：Diameter 5.5mm~10mm, 75~125mm of length, from
It is 25~50mm to attack screw to enter the depth of CLT plates.
Further, the thickness of the CLT plates is 60~100mm.
Further, 40~60mm of thickness of the concrete slab, concrete slab configure single-layer bidirectional reinforcing bar.
The present invention also provides the construction methods of above-mentioned novel combination type floor, include the following steps：
S1, it is spaced apart equipped with several baltimore grooves on the CLT plates；
S2, several tapping screws are laid in the baltimore groove, the tail portion of tapping screw is made to be fixed in concave groove, head dew
Go out outside CLT plates；
S3, the casting concrete plate on CLT plates and tapping screw.
The principle of the present invention is that the present invention is poured by the cooperation of baltimore groove and tapping screw on orthogonal laminated wood (CLT)
Concrete slab is built, orthogonal laminated wood is formed in lower concrete slab in upper composite structure, realizes the two collective effect.CLT planks
After opening up baltimore groove, concrete pours into concave groove, further increases the bond strength between plank and concrete, conveniently pushes away
It is wide to be applied to more high-rise timber structures.
Compared with prior art, the beneficial effects of the present invention are：
1, novel combination type floor of the invention realizes CLT plates and concrete slab collective effect, the advantages of both having both, energy
The rigidity and bearing capacity for enough effectively improving the wooden superstructure, effectively improve vibration isolation and sound insulation property and fire resistance.
2, according to experiment measured result, compared with pure CLT plates do floor, the bending stiffness of combined type floor of the invention can
600% or so are promoted, anti-bending bearing capacity can promote 400% or so.Compared with concrete floor, when same stiffness or bearing capacity,
The present invention can effectively mitigate the dead weight of floor.
3, construction method of the invention changes existing floor slab construction process, provides a kind of timber structure to more high-rise hairs
Exhibition provides a kind of settling mode of floor.
Description of the drawings
