Abstract
The invention discloses a superposed slab/beam with an enhanced steel bar truss and a support connecting method thereof. And (3) pre-arranging a common small triangular truss in the reinforced steel bar truss at the support part of the laminated slab/beam, and after the reinforced steel bar truss is arranged in place, drawing out the small triangular truss and anchoring the small triangular truss into the beam/column or the opposite laminated slab. The reinforced triangular steel bar truss structure formed by the upper and lower chord composite steel bars overcomes the defect of low rigidity of the existing steel bar truss, can realize zero support in the construction process, reduces the construction workload and lowers the construction cost. The invention takes the built-in small triangular truss as the support connecting piece, thereby ensuring the reliability of the support connection. In addition, the invention has simple structure and low manufacturing cost, and is convenient for direct application of engineering.
Description
Technical field
The invention belongs to the concrete structure engineering technical field, relate in particular to a kind of superimposed plates/beam with enhancement mode reinforcing bar truss and bearing method of attachment thereof.
Background technology
No matter current be Cast-in-situ Concrete Structural Engineering or prefabricated concrete structure engineering, superimposed sheet/beam, especially superimposed sheet has obtained application more and more widely, has formed the various ways such as steel board, prestressed concrete overlapped slab, steel bar girder concrete folding plate.Above-mentioned template has all been considered the problem that construction period saving precast plate supports, but by relevant criterion analysis and engineering site applicable cases, its bottom support quantity is still larger, and the rigidity less of prefabricated panel does not reach the target of construction period zero branch support yet.
Simultaneously, in the practice of construction process of superimposed sheet/beam, because superimposed sheet/beam support place bearing length is too short and the bearing place stretches out the upper and lower string muscle of truss impact construction and usually cut off or cut off, cause superimposed sheet/beam support place to connect too weak, the engineering accident that superimposed sheet/beam drops from bearing generally occurs.
Summary of the invention
The object of the present invention is to provide a kind of superimposed plates/beam with enhancement mode reinforcing bar truss and bearing method of attachment thereof, be intended to solve the engineering problem that bottom support quantity is bigger than normal, prefabricated panel rigidity is less and the bearing place easily drops lost efficacy that existing steel bar girder plate exists.
The present invention realizes like this, a kind of superimposed plates/beam with enhancement mode reinforcing bar truss and bearing method of attachment thereof, this stack plate-girder with enhancement mode reinforcing bar truss comprises the composite reinforcing steel bar that winds up, lower edge composite reinforcing steel bar, web member reinforcing bar, and the bearing place is connected as connector by built-in little English truss.
Wind up between composite reinforcing steel bar, lower edge composite reinforcing steel bar, web member reinforcing bar by being welded to connect.
Further, upper and lower string composite reinforcing steel bar can need to be optimized design according to loading characteristic and rigidity of section, can adopt bi-steel or many reinforcing bars form.
Further, built-in little English truss can be according to stressed needs and constructability, adopts the compound reinforcing bar or be inverted little English truss of winding up.
Superimposed plates/beam with enhancement mode reinforcing bar truss provided by the invention and bearing method of attachment thereof, by adopting the composite reinforcing steel bar of bi-steel or many reinforcing bars, form enhancement mode reinforcing bar truss; The triangle reinforcing bar trussed construction that the upper and lower string composite reinforcing steel bar of the present invention forms, overcome existing steel bar girder rigidity defect on the low side, and can realize the support of work progress zero branch, reduces the construction working amount, reduces construction costs.The present invention is usingd built-in little English truss as the bearing connector, has guaranteed the reliability that bearing connects.In addition, the present invention is simple in structure, and cost of manufacture is low, and a kind of stack plate-girder of high-intensity steel bar girder is provided.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the enhancement mode reinforcing bar trussed construction that the embodiment of the present invention provides.For convenience of explanation, only show part related to the present invention.
The enhancement mode reinforcing bar truss of the embodiment of the present invention, comprise the composite reinforcing steel bar that winds up, lower edge composite reinforcing steel bar, web member reinforcing bar, between the composite reinforcing steel bar that winds up, lower edge composite reinforcing steel bar, web member reinforcing bar by being welded to connect.
As a prioritization scheme of the embodiment of the present invention, upper and lower string composite reinforcing steel bar can adopt bi-steel or many reinforcing bars form.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, the enhancement mode reinforcing bar truss of the embodiment of the present invention mainly is comprised of the composite reinforcing steel bar 1 that winds up, lower edge composite reinforcing steel bar 2 and web member reinforcing bar 3, adopt wind up reinforcing bar 1 and the lower edge reinforcing bar 3 of bi-steel or many reinforcing bars to be arranged in parallel, the reinforcing bar 1 that winds up is connected with lower edge reinforcing bar 3 by web member reinforcing bar 2, web member reinforcing bar 2 is connected with lower edge reinforcing bar 3 with the reinforcing bar 1 that winds up by spot welding, forms the triangle steel bar girder that upper and lower string meets reinforcing bar; Web member reinforcing bar 2 is the single reinforcement structure.
The present invention adopts the triangle steel bar girder of upper and lower string composite reinforcing steel bar, forms the steel bar girder effectively strengthened, and overcomes existing steel bar girder rigidity characteristics on the low side; Enhancement mode reinforcing bar truss can be applicable in superposed beam/plate, strengthen prefabricated panel in work progress and rigidity, can realize the purpose of zero branch support in work progress reducing the construction working amount, reduce construction costs.
Fig. 2 shows the bearing method of attachment of the superimposed sheet/beam with enhancement mode reinforcing bar truss that the embodiment of the present invention provides.For convenience of explanation, only show part related to the present invention.
