Description
Technical field
The utility model is for providing a kind of self-supporting prestressing force Covered with Angles light aggregate concrete composite beams in assembled integral superposed floor structural system building course, as superposed floor template die plate self-supporting system, until superposed floor board concrete, reach after design strength, as superstructure girt strip structure and superposed floor shared external load simultaneously.
Background technology
Concrete rib beam building roof structure can be divided into cast-in-place integral formula by construction method at present, assembling and the whole three types of assembling.The one, cast-in-place integral superstructure, by reinforcing bar is installed in template, and concreting has good globality.The 2nd, assembly concrete superstructure, the Structural Floor System that it is comprised of precast beam, plate, has speed of application fast, is convenient to suitability for industrialized production and mechanized construction, saves labour.The 3rd, assembled integral concrete floor system, it,, by after the member installation in position of every pre-erection, makes it to become overall structure by definite part cast-in-situ concrete.Its advantage is cast-in-place advantage and the one with joining formula superstructure of collection, compares with Cast-in-situs type superstructure, can reduce formwork and concrete construction wet trade amount, compares with precast assemble floor, and its structural entity is good.The weak point of ordinary concrete girt strip Structural Floor System.
1, cast-in-place integral superstructure shortcoming is that template materials are many, construction wet trade amount is large, speed is slow, long in time limit.
2, assembled integral concrete floor system structural integrity, poor seismic behavior, be difficult to guarantee that component node is rigid joint, will have a strong impact on the promotion and application of this structural system.
3, common assembled integral concrete floor system adopts precast unit weight large owing to relating to, be difficult to adapt to large-span space structure, while adopting combination steel work, relate to steel member integrated and local poor stability, steel work and concrete shear key and can not guarantee the shortcomings such as steel member and cast-in-place concrete structure sex change coordination, steel member construction costs height, limited the application of the type structure.
Summary of the invention
Problem for above-mentioned existence, it is a kind of by assembled by design to prefabricated Covered with Angles light weight aggregate concrete composite member that the utility model provides, form Covered with Angles light weight aggregate concrete combined type superposed beam, then combined type superposed beam is applied to prestressing force, this compound beam obtains enough Rigidity and strengths, makes the superposed floor cast-in-place concrete construction that this compound beam is the later stage that reliable self-supporting system is provided.Solving the technical scheme that its technical problem adopts is:
The prefabricated Covered with Angles light aggregate concrete composite beams of a kind of prestressing force, it comprises beams encased in steel hoops (1), shear connector (2), prestressed pore passage bellows (3), prestressing tendon (4), line style positioning control part (5), light weight aggregate concrete (6), composite member seam (7), it is characterized in that: prefabricated Covered with Angles light weight aggregate concrete composite member cross section by U-shaped beams encased in steel hoops (1), shearing chaining part (2), line style positioning control part (5) are set within it, the light weight aggregate concrete (6) of laying prestressed pore passage bellows (3) and filling forms; The structure of the prefabricated Covered with Angles light aggregate concrete composite beams of self supporting type prestressing force is by assembled formation of a plurality of prefabricated Covered with Angles light weight aggregate concrete composite member, and in the prestressed pore passage bellows (3) of portion, wears prestressing tendon (4) within it.
A welds shear connector in Covered with Angles groove, makes Covered with Angles girder steel form the flute profile girder steel of the half opening of reasonable stress;
B presses the design of prestressing force line style, at shear connector place welding line style positioning control part;
C prestressed duct bellows, is formed with binding prestress beam hole road;
D pours into light weight aggregate concrete in Covered with Angles groove, forms prefabricated Covered with Angles light weight aggregate concrete composite member;
The assembled Prefabricated composite part of E, is arranged on frame column, and junction connection prestressed pore passage, and injects concrete at seam crossing;
F penetrates prestress wire in prestressed pore passage, stretch-draw prestressing force, and prestressing tendon is anchored at post outside, forms prestressing force Covered with Angles light aggregate concrete composite beams.
Its beneficial effect is: this compound beam adopts light weight aggregate concrete to alleviate dead load, increased the Rigidity and strength of girder steel, in conjunction with high efficient prestress technology, further improved compound beam stress performance, significantly improve the Rigidity and strength of compound beam, for the construction of superposed floor plate provides reliable self supporting type combined beam structure system.
Accompanying drawing explanation
As shown in Figure 1, 2, 3, the toponym of each digital representative and effect thereof are listed in the table below:
What Fig. 1 represented is Covered with Angles girder steel cross sectional shape, and it and shear connector relation.Its cross section different parts steel plate thickness is pressed the internal force design of compound beam cross section; What Fig. 2 represented is prestressing tendon form, and prestressing tendon cloth muscle form form can adopt curve or straight line cloth muscle; What Fig. 3 represented is Covered with Angles light aggregate concrete composite beams schematic diagram, by stretch-draw prestressing force steel strand, forms prestressing force Covered with Angles light weight aggregate concrete combined type superposed beam, becomes the self-supporting compound beam system of floor structure cast-in-place concrete construction.
The specific embodiment
The utility model relates to the prefabricated Covered with Angles light aggregate concrete composite beams of a kind of prestressing force.Its major part has adopted prefabricated Covered with Angles light weight aggregate concrete composite member to be assembled into compound beam (Fig. 1).Utilize high efficient prestress technology (Fig. 2), formed assembled integral prestressing force Covered with Angles lightweight aggregate compound beam (Fig. 3), for the cast in site floor engineering construction in later stage provides safe and reliable self support structures.This utility model has been given full play to each combinatorial material mechanics performance, has formed simple structure, and technical security is reliable, easy construction prestress combined beam.
It comprises beams encased in steel hoops 1, shear connector 2, prestressed pore passage bellows 3, and prestressing tendon 4, line style positioning control part 5, light weight aggregate concrete 6, composite member seam 7, be specifically implemented as follows:
A is by lay prestressed pore passage bellows in Covered with Angles groove, and builds light weight aggregate concrete, forms prefabricated Covered with Angles light weight aggregate concrete composite member;
B passes through assembling combination part, and at composite member seam crossing concreting, forms Covered with Angles light aggregate concrete composite beams;
C is arranged on compound beam on frame column, stretch-draw prestressing force bundle, and be anchored on frame column, form self-supporting compound beam, for the engineering construction of superposed floor plate provides reliable template self-supporting system.
