Description
(1) technical field
The present invention relates to a kind of hollowcore slab prefabricated units.
(2) background technology
Advantages such as at present, the building of brick mix structure and reinforced concrete structure major part adopts precast hollow slab as floor structure, and it is fast that this floor structure has speed of application, and cost is low.But, only use the cement mortar joint filling, thereby globality is poor, is unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur owing to firmly do not link between adjacent two precast hollow slabs.In order to address the above problem, a lot of building have adopted the method for cast-in-place concrete cored (solid, hollow), though solved antidetonation and problems of crack, will use template in a large number during construction, have not only increased expense, and have slowed down speed of application, have prolonged the duration.Application number is " a kind of combination concrete rib floor structure " utility model patent of 00203695.9, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is placed at interval, on prefabricated plate, be fixed with formwork, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connects as one with dark rib.Though this floor structure can be saved a large amount of templates, accelerate construction progress, but because formwork is what to separate with prefabricated plate, its strength and stiffness are corresponding relatively poor, thereby the problem that exists formwork easily to break, simultaneously, formwork is fixed on and does not relate to concrete fixed form on the prefabricated plate, thereby fixed in place is difficult.And the patent No. is 93206310.1 shuttering member utility model patent, it constitutes hollow mould shell by sidewall and formwork upper plate and is connected to form totally-enclosed cavity polyhedral structure with lower shoe again, prefabricated ribs is arranged in it, during use member is placed on the supporter of floor gap, formation bonded to one another is whole between cast-in-place main rib, the shuttering member.When this kind member uses, be a kind of prefabricated noggin piece purely, the ribs in the die housing only is used to support formwork, can not participate in the whole stressed of superstructure.And when being applied in than the large spatial structure superstructure, its stress performance is also phase strain differential thereupon, do not have time rib between the cast-in-place main rib and connect, thereby make the size of main rib need the phase strain big, or the quantity of main rib increases, and causes material usage to increase, and cost increases.For this reason, the applicant has applied for that November 15 calendar year 2001 publication number is that CN1349028A, name are called " a kind of use for cover of storied building in space structure combination rib prefabricated units " patent of invention, its disclosed prefabricated unit includes formwork and structure base plate, hollow mould shell and structure base plate connect into integral body, it is characterized in that having 2 hollow mould shells on the structure base plate at least alternately, its side and structure base plate constitute at least one cast-in-place structural time rib die cavity, and other lateral surface of hollow mould shell constitutes the side template of cast-in-place structural main rib or beam or wall.Like this, because on the prior art basis, at least 2 hollow mould shells and at least 1 cast-in-place structural time rib die cavity (internal-rib die cavity) are arranged on the structure base plate, on the structure base plate, just can form cast-in-place structure time rib, fellowship structure base plate, main rib, upper plate stressed, form two-way main rib time rib force structure, problems of the prior art have not only been solved, but also overall performance, the anti-seismic performance of superstructure have further been improved, reduced the thickness of superstructure, alleviate dead load, reduced cost.But this prefabricated units are in carrying, work progress, and its structure base plate is prone to the phenomenon that fractures, thereby the breakage rate of prefabricated units is big, and carrying, construction inconvenience have increased construction cost.For this reason, develop a kind of novel hollowcore slab and be urgent need with prefabricated units.
(3) summary of the invention
The object of the present invention is to provide a kind of hollowcore slab prefabricated units, have characteristics such as intensity height, non-frangibility, carrying, easy construction.
Solution of the present invention is on the basis of existing technology, comprise the structure base plate, protrude block, there are at least four to protrude block alternately on the structure base plate, protrude the alternate cavity internal-rib that is spaced apart between the block, protruding block and structure base plate constitutes whole, it is characterized in that described protrusion block is arranged in parallel on same axis, the spacing of cavity internal-rib is 30-130mm, and at least one the support spare that connects the adjacent protrusion block of support is arranged at the top of cavity internal-rib.Like this, because protruding block is arranged in parallel on same axis, the spacing of cavity internal-rib is 30-130mm, at least one the support spare that connects the adjacent protrusion block of support is arranged at the top of cavity internal-rib, thereby hollowcore slab is bigger with the intensity and the rigidity of prefabricated units, and shock resistance is better, and the structure base plate is frangibility more not, carrying is more convenient with construction, thereby has reached purpose of the present invention; Simultaneously, hollowcore slab also has characteristics such as simple in structure, easily manufactured, that cost is low with prefabricated units, the hollowcore slab, hollow building cover, roof system, sole plate, body of wall and the hollow bridges that are applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.
