Abstract
The invention discloses a method for supporting an upper raft reinforcement steel bar frame of an underground raft by using anti-floating anchor rods. A structure for supporting the underground raft by using the anti-floating anchor rods comprises the upper raft reinforcement steel bar frame, a lower raft plate steel bar frame paved on the ground and a support structure for supporting the upper raft steel bar frame. The support structure comprises multiple groups of the anti-floating anchor rods and multiple support rods. Each group of the anti-floating anchor rods are buried in the underground in a fixed interval and the tops are fixedly connected to the support rods. The upper raft reinforcement steel bar frame is arranged on the support rods and includes steps of: dividing each group of anti-floating anchor rods into multiple groups, each group of the anti-floating anchor rods being buried in the underground in the fixed interval; the tops of the multiple groups of anti-floating anchor rods fixedly connecting the support rods; arranging the upper raft reinforcement steel bar frame on the support rods. In the method for supporting the upper raft reinforcement steel bar frame of the underground raft by using the anti-floating anchor rods, split head ribs are replaced by the anchoring parts of the raft anti-floating anchor rods in a basement, and the advantages of convenient construction, safety and reliability, green and energy conservation, and low construction cost can be achieved.
Description
Technical field
The present invention relates to a kind of braced structures and method, espespecially a kind of method of utilizing raft plate reinforced frame on anti-float anchor rod support underground raft plate.
Background technology
Consult shown in Fig. 3, the structure of underground raft plate mainly comprises raft plate reinforced frame 1 and lower raft plate reinforced frame 2 on one, in the time setting up, by supporting steel bar 6, upper raft plate reinforced frame 1 is provided support, keep between the two every distance, after upper raft plate reinforced frame 1 has been set up with lower raft plate reinforced frame 2, carry out the concrete complete underground raft plated construction of building and then form.When the comprehensive load producing due to building deadweight and other external factor is not enough to buoyancy that balance underground water produces, must apply certain vertical external force with balance buoyancy at sole plate, in order to prevent the floating of underground raft plate, complex root anti-float anchor rod 3 can be set conventionally, its lower end is embedded in to ground, upper end extends between raft plate reinforced frame 1 and lower raft plate reinforced frame 2, after the concreting of underground raft plate completes, the upper end of anti-float anchor rod 3 is anchored between upper raft plate reinforced frame 1 and lower raft plate reinforced frame 2, thereby the stretching resistance of utilizing the tensile strength of anchor pole self to produce, the uplift resistance that frictional force between anchor pole and soil layer produces, trend to sole plate floating retrains, play the effect of opposing foundation floating.
But, in above-mentioned work progress, playing the support supporting steel bar 6 that above raft plate reinforced frame 1 acts on adopts large gauge ribbed bar to be made, and spacing is less, need to use more reinforcing bar to make, high material consumption needs to expend more manually processing simultaneously, and there is the unstable and easy flexural deformation of reinforced bar support, in construction, be not easy to use, adjust the problems such as difficulty, therefore really have further improved necessity.
Summary of the invention
The object of the invention is to overcome the defect of prior art, and provide a kind of method of utilizing raft plate reinforced frame on anti-float anchor rod support underground raft plate, realize and utilized basement raft plate anti-float anchor rod to replace supporting steel bar, had advantages of that convenient, safe and reliable, the green energy conservation of construction, construction cost are low.
The technical scheme that realizes above-mentioned purpose is:
A kind of structure of utilizing anti-float anchor rod support underground raft plate of the present invention,
Comprise that lower raft plate reinforced frame and that raft plate reinforced frame, on is layed in ground supports the braced structures of described upper raft plate reinforced frame, described braced structures comprises plural groups anti-float anchor rod and a plurality of support bar, be embedded in ground, and top and described support bar are fastenedly connected the described anti-float anchor rod constant spacing of each group; Described upper raft plate reinforced frame is set up on described support bar.
Every group of above-mentioned anti-float anchor rod comprises three anti-float anchor rods.
Above-mentioned three anti-float anchor rod tops and the welding of described support bar.
Above-mentioned three anti-float anchor rod tops and described support bar colligation.
A kind of method of utilizing raft plate reinforced frame on anti-float anchor rod support underground raft plate of the present invention.
Comprise step:
Anti-float anchor rod is divided into plural groups, respectively organizes and between anti-float anchor rod, be embedded in ground constant spacing;
At the affixed support bar in the top of described plural groups anti-float anchor rod;
Described upper raft plate reinforced frame is set up on described support bar.
Every group of above-mentioned anti-float anchor rod comprises three anti-float anchor rods; The top of described three anti-float anchor rods and the welding of described support bar.
Every group of above-mentioned anti-float anchor rod comprises three anti-float anchor rods; The top of described three anti-float anchor rods and described support bar colligation.
The present invention has been owing to having adopted above technical scheme, makes it have following beneficial effect to be:
Described anti-float anchor rod top and support bar are fastenedly connected, realization utilizes anti-float anchor rod top connecting portion as support, make to play when anti-float anchor rod maintenance is original prevents underground raft plate Float upward function the effect of anti-float anchor rod replacement raft plate supporting steel bar, there is the use amount of saving reinforcing bar, reduce artificial expending, play reduce costs, energy-conservation effect, and be difficult for being trampled being damaged deformation.
