Abstract
The invention discloses a structure utilizing anti-floating anchor rods to support underground raft plates, which comprises an upper-row raft plate steel bar frame, a lower-row raft plate steel bar frame paved on the ground and a support structure supporting the upper-row raft plate steel bar frame. The structure utilizing the anti-floating anchor rods to support the underground raft plates is characterized in that the support structure comprises a plurality of groups of anti-floating anchor rods and a plurality of support rods, the plurality of groups of anti-floating anchor rods are embedded in the ground at fixed intervals, the tops of the anti-floating anchor rods are in fastening connection with the support rods, and the upper-row raft plate steel bar frame is arranged on the support rods. The structure and a method which utilize the anti-floating anchor rods to support the underground raft plates are adopted, the fact that anchoring portions of the anti-floating anchor rods of basement raft plates replace horse stool ribs is achieved, and the structure and the method have the advantages of being convenient and fast to construct, safe, reliable, green, energy-saving and low in construction cost.
Description
Technical field
The present invention relates to a kind of braced structures and method, refer to a kind of structure and method of utilizing anti-float anchor rod to support underground raft plate especially.
Background technology
Consult shown in Figure 3; The structure of underground raft plate mainly comprises raft plate reinforced frame 1 and following raft plate reinforced frame 2 on one; When setting up, go up raft plate reinforced frame 1 through 6 pairs in split heads muscle and provide support, keep separated distance between the two; After treating that raft plate reinforced frame 1 and following raft plate reinforced frame 2 are set up completion, carry out the concrete complete underground raft plated construction of building and then form.Because when the comprehensive load that building deadweight and other external factor produce is not enough to buoyancy that balance underground water produced; Must apply certain vertical external force with balance buoyancy at sole plate; In order to prevent the come-up of underground raft plate; Usually complex root anti-float anchor rod 3 can be set, its lower end is embedded in ground, the upper end extends between raft plate reinforced frame 1 and the following raft plate reinforced frame 2; The upper end of anti-float anchor rod 3 promptly was anchored between raft plate reinforced frame 1 and the following raft plate reinforced frame 2 after the concreting of treating underground raft plate was accomplished; Thereby the uplift resistance that frictional force produced between stretching resistance, anchor pole and the soil layer that the tensile strength of utilizing anchor pole self is produced, the trend that sole plate is floated retrains, and plays the effect of opposing foundation floating.
But, works the split heads muscle 6 that supports upward raft plate reinforced frame 1 effect in the above-mentioned work progress and adopt big specification reinforcing bar to be made, and spacing is less; Need to use more reinforcing bar to make, high material consumption need expend more manual work simultaneously and process; And has the unstable and flexural deformation easily of reinforced bar support; Be not easy in the construction use, therefore problems such as adjustment difficulty have further improved necessity really.
Summary of the invention
The objective of the invention is to overcome the defective of prior art; And a kind of structure and method of utilizing anti-float anchor rod to support underground raft plate is provided; Realized utilizing basement raft plate anti-float anchor rod to replace the split heads muscle, had that construction is convenient, safe and reliable, a green energy conservation, advantage that construction cost is low.
The technical scheme that realizes above-mentioned purpose is:
A kind of structure of utilizing anti-float anchor rod to support underground raft plate of the present invention,
Comprise that the following raft plate reinforced frame and that raft plate reinforced frame, on is layed in ground supports the said braced structures that goes up raft plate reinforced frame; Said braced structures comprises plural groups anti-float anchor rod and a plurality of support bar; Each is embedded in ground with organizing said anti-float anchor rod constant spacing, and top and said support bar are fastenedly connected; The said raft plate reinforced frame of going up is set up on the said 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 said support bar.
Above-mentioned three anti-float anchor rod tops and said support bar colligation.
A kind of method of utilizing anti-float anchor rod to support raft plate reinforced frame on the underground raft plate of the present invention.
Comprise step:
Anti-float anchor rod is divided into plural groups, and each is organized and is embedded in ground between the anti-float anchor rod constant spacing;
The affixed support bar on the top of said plural groups anti-float anchor rod;
The said raft plate reinforced frame of going up is set up on the said support bar.
Every group of above-mentioned anti-float anchor rod comprises three anti-float anchor rods; The top of said three anti-float anchor rods and the welding of said support bar.
Every group of above-mentioned anti-float anchor rod comprises three anti-float anchor rods; The top of said three anti-float anchor rods and said support bar colligation.
The present invention has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
Said anti-float anchor rod top and support bar are fastenedly connected; Realization utilizes anti-float anchor rod top connecting portion as support; Make anti-float anchor rod keep original and play the effect that anti-float anchor rod replaces raft plate split heads muscle when preventing underground raft plate come-up effect, have the use amount of practicing thrift reinforcing bar, reduce artificial expending; Play reduce cost, energy-conservation effect, and be difficult for being trampled and destroy distortion.
