Abstract
A kind of large-span prestressed F plate of upper bands bending steel muscle comprises two plate faces between rib of slab and rib of slab and a side wing edge, it is characterized in that T plate to remove a side wing edge or a rib is moved on to edges of boards to form F plate, especially rib top is with bending steel muscle on its top, and under rib of slab, embedded part connects tensile reinforcement.Large-span concrete F plate top bending steel muscle is connected with post, utilize the shearing that the slugging under F rib of slab on embedded part and beam or on bracket beam provides, be less than or equal to the pulling force that on F plate, on bending steel muscle and post, bar connecting is formed, form restraining moment according to rib of slab height, thus formation steel connects frame girder construction.
Description
One, art: building engineering field
Two, background technology: large span prestressed concrete T plate is used for frame construction, there is no the structural system matched at present, and cannot use, intend Vierendeel girder cost also larger, especially transverse strands stud is too many, oversize, cost is too large, and high-altitude support shuttering is loaded down with trivial details, and considerable expert queries and thinks unreliable, and must be that 5 meters, 7.5 meters, 9.9 meters fixed frames are apart from not conforming to many factory building technological requirements to the sheet-pile net of 2.4 meters wide.
Three, summary of the invention
The large span prestressed concrete F plate and the frame structure system thereof that the invention provides a kind of upper bands bending steel muscle have solved above-mentioned drawback.A kind of large span prestressed concrete F plate of upper bands bending steel muscle comprises two faces of plate between rib of slab and rib of slab and a side wing edge, it is characterized in that T plate to remove a side wing edge or rib of slab is moved to edges of boards to form F plate, such effective area does not reduce, and plate top especially rib top is provided with bending steel muscle.
Further upper bands bending steel muscle large span prestressed concrete F plate, the bending steel muscle amount two ends on plate top are many, middle few.
The large span prestressed concrete F plate of further upper bands bending steel muscle, arranges joint bar along in bending steel muscle up and down concrete.
The large span prestressed concrete F plate of further upper bands bending steel muscle, position, termination is provided with dowel.
The large span prestressed concrete F plate of further upper bands bending steel muscle, is characterized in that: overlapping layers can be established in top.
The large span prestressed concrete F plate of further upper bands bending steel muscle, is characterized in that: both sides of the chest can remove 4 angle of ribs, to reduce floor height.
The large span prestressed concrete groove type plate of further upper bands bending steel muscle, is characterized in that: the horizontal power transmission reinforcing bar of embedded part connection is to be delivered to thrust suffered by plate end on the prestressed reinforcement of middle part.
Further large span prestressed concrete F plate and frame structure system, is characterized in that: under described large span prestressed concrete F rib of slab, embedded part connects tensile reinforcement.
Further a kind of large span prestressed concrete F plate framework structural system comprises: the large-span prestressed F plate of frame column, frame rails, upper bands bending steel muscle, on concrete slab, especially rib top arranges bending steel muscle, with bar connecting on post, slugging on bracket on embedded part and post under plate end, thus form a kind of large span prestressed concrete F plate framework structure.
Further large span prestressed concrete F plate framework structural system, corresponding with post for F rib of slab, bar connecting, also 2 adjacent ribs removing the corresponding edge of a wing can be connected together, the middle cementation of fissures, both sides of the chest top bending steel muscle is connected with post together, and single rib, two rib can also strengthen rear and post bar connecting.Under F plate termination, on embedded part and bracket, embedded part welds and utilizes the shearing that on embedded part and bracket, slugging provides under F plate termination further, be less than or equal to the pulling force that on top bending steel muscle and post, bar connecting is formed, form restraining moment according to F rib of slab height, this then becomes hinged frame into framework.
Further large span prestressed concrete F plate framework structural system, it is characterized in that: utilize the shearing that the slugging under F rib of slab on embedded part and beam or on bracket beam provides, be less than or equal to the pulling force that on F plate, on bending steel muscle and post, bar connecting is formed, form restraining moment according to rib of slab height, thus formation steel connects frame girder construction.
The large span prestressed concrete F plate framework structural system of further top bending steel muscle, has iron embedded part to be connected with steel in frame rails or embedded part bottom rib two ends.
Four, accompanying drawing illustrates: figure is large-span prestressed T plate frame structure system schematic diagram, and Fig. 1-1 is front elevation view, and Fig. 1-2 is side elevational view,
Five, detailed description of the invention: as shown in the figure: 1 is post; 2 is bracket beam on post; 3 large-span prestressed F plates; 4 is F plate top bending steel muscle.
Bracket beam 2 on frame column 1 and post is built by conventional method, or T plate 3 pairs of ribs merging that two are removed the corresponding edge of a wing are arranged on the bracket beam of end frame trestle 1, plate top bending steel muscle 4 is connected with embedded part on bracket beam with post steel plate bottom built-in fitting, or the lower tension reinforcing bar of plate and post bar connecting, do secondary above again and water layer and form frame construction.
