Abstract
The invention relates to a large-span prestressed double-T laminated slab. The slab has the following beneficial effects: a lamination layer is arranged on a double-T laminated slab bottom slab, thus forming an assembled monolithic structure with safety performance like that of the cast-in-situ structure; and four angles of ribs below ribs of the slab are removed and the slab is put on a beam or an L-shaped beam in a broken manner, thus reducing the layer height.
Description
Technical field
The present invention relates to a kind of prefabricated reinforced concrete bearing carrier, particularly relate to a kind of rib Xia Sijiao, superimposed a kind of large-span prestressed double T superimposed sheet in top of removing.
Background technology
The double T plate is the prefabricated reinforced concrete bearing carrier that plate, beam combine, and is made up of roomy panel and two narrow and high ribs.Its panel is horizontal load-carrying members, is again the pressure zone of vertical load-bearing rib.So the double T plate has good structural mechanical property, clear and definite power transmission level, succinct geometry is a kind of large span, big area coverage and both economical bearing carrier of can be made into.
At present, large span prestressed concrete double T plate is used widely in industrial premises and other civilian construction structures as a kind of standard concrete prefabricated units, and fully manifests its superiority in the industrialization of construction industry field.Use the building of double T plate big because of its space, design simplification, it is convenient to construct, and comprehensive cost is low, is accepted by users gradually.
That but the double T plate is done is civilian, on the utilities building, and particularly classroom, power plant, market, supermarket etc. are architectural, because as more relatively poor than cast-in-place in its globality of prefabricated units, the safety; Even and plate is disconnected is placed on the beam on the L beam beam of falling T, floor height is bigger, and cast-in-place prestressed limitation is bigger; Common nonprestressed reinforcement concrete cast-in-situ; Span is very little, and reinforced steel bar strength has only about 1/5 of prestress steel, waste material significantly.
Summary of the invention
The objective of the invention is to present double T plate as the relatively poor present situation of prefabricated units globality safety; Greatly waste steel and concrete, present situation that cast-in-place prestressed operation easier is big again significantly with floor height; A kind of large span double T superimposed sheet that removes following four angle of ribs of rib is provided; Thereby realized the cast-in-place cast in place and precast construction of treating as of prestressing force double T plate, and not only used prestress steel, saved about 5 times steel and a large amount of concrete; Increased globality, safety again, reduced floor height again simultaneously, saved cost.
Technical scheme of the present invention is following:
A kind of large-span prestressed double T plate superimposed sheet comprises double T superimposed sheet base plate and overlapping layers, and the superimposed base plate of double T top is provided with overlapping layers.
Further, remove four angle of ribs under the rib of the superimposed base plate of double T.
Further, exposed steel bar or plate face hacking are arranged on the superimposed base plate plate of the double T face.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, double T superimposed sheet base plate, 2, the angle of rib.
The specific embodiment
Large span prestressed concrete double T superimposed sheet of the present invention, like Fig. 1, after removing following four angle of ribs 2 of double T superimposed sheet base plate 1 rib, prestressed reinforcement invariant position or rise to draw with curve and avoid removing the position; Remove four angle of ribs 2 weakened parts afterwards, the rib both sides add iron plate or the U-iron plate is reinforced, and stay exposed steel bar on the plate face of double T superimposed sheet base plate 1, and overlapping layers is established on top.
Large span prestressed concrete double T superimposed sheet of the present invention, the large span prestressed concrete double T plate of following four angle of ribs 2 of rib of slab of removing double T superimposed sheet base plate 1 be placed on the beam or the bottom girder of L beam, the beam of falling T on, down gap and institute break, and the beam put coincide and the low beam of the L beam beam of falling T is identical; Reduced floor height; Reduce cutting depth, save cost, stay exposed steel bar on the plate face of double T superimposed sheet base plate 1; Plate face hacking; On establish overlapping layers, steel and concrete are saved in agents enhance overall property, safety significantly.
Claims (3)
1. a large-span prestressed double T plate superimposed sheet comprises double T superimposed sheet base plate and overlapping layers, it is characterized in that: the superimposed base plate of double T top is provided with overlapping layers.
2. large-span prestressed double T plate superimposed sheet base plate as claimed in claim 1 is characterized in that: remove four angle of ribs under the rib of the superimposed base plate of said double T.
3. like claims 2 described large-span prestressed double T plate superimposed sheets, it is characterized in that: exposed steel bar or plate face hacking are arranged on the superimposed base plate plate of the double T face.
