Background technique
Currently, the immediate prior art: after workshop newly increased load, foundation bearing capacity is unsatisfactory for requiring, and general use adds
Big bottom of foundation area method and grouting and reinforcing method increase bottom of foundation area method and need to excavate basis, again reinforcement, casting concrete.
Construction time is long, and construction risk is big, and investment is high.Grouting and reinforcing method is with the compactness, permeability and compression strength that change soil layer
Purpose increases soil layer under basis by caking property and compression strength, thus solid base, protection structures, but the expansion of this method slurries
It is not easy to control to dissipate radius, reinforces groundwork bearing capacity and is not easy quantitative analysis, grouting process is complicated, and grouting amount is big, costly.
In conclusion problem of the existing technology is:
(1) prior art construction is cumbersome.It needs excavation foundation just and can be carried out reinforcing, cause time-consuming and laborious.
(2) consolidated subsoil effect is not easy to control, and project amount is big, costly.
Solve the difficulty of above-mentioned technical problem: duration, cost, quality are not easy to control.
It solves the problems, such as the meaning of above-mentioned technical problem: handling ground well, not only whether the built engineering of relationship is reliable, Er Qieguan
It is the size of built construction investment;Ground problem is handled well with preferable economic benefit;Improving basement process level can guarantee
Construction quality accelerates engineering construction speed, saves engineering construction investment.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of new steel structure factory building foundation bracing means and sides
Method.
The invention is realized in this way a kind of new steel structure factory building foundation bracing means, the new steel structure workshop
Strengthening of foundation device is provided with
Steel column is mounted on basic short column, and ground beam pours tight on the left of basic short column top side, indoor reinforced concrete terrace
Adjacent basis short column, ground beam and top surface are substantially flush, and are equipped with anchor pole on ground beam waist location.
Another object of the present invention is to provide a kind of based on the novel of the new steel structure factory building foundation bracing means
Steel-structure factory building strengthening of foundation method, the new steel structure factory building foundation reinforcement means include: the ground on footing foundation top
Base beam-ends head squeezes into more anchor poles, passes through the additional levels pulling force of anchor pole balanced basis.
Further, anchor pole is seamless steel pipe or common joint bar grouting rock bolt.
The new steel structure factory building foundation reinforcement means further comprises:
The drilling of grade beam waist location, hole location avoid stirrup position, are put into reinforced anchor bolt, are in the milk, end sealing off and covering anchorage;
If the soil body is not easy pore-forming, using seamless steel pipe grouted rock bolt, steel pipe tube body opens quincunx injected hole, and steel pipe is in place
Afterwards, pressure injection cement slurry is filled steel pipe is inside and outside, keeps steel pipe integral in conjunction with the soil body.
Implement the novel of the new steel structure factory building foundation reinforcement means another object of the present invention is to provide a kind of
Steel-structure factory building.
In conclusion advantages of the present invention and good effect are as follows: the present invention carries out bolt anchorage method and reinforces position, general
Logical joint bar grouting rock bolt, seamless steel pipe grouted anchor bar, the grade beam end punching on footing foundation top.It is easy for construction, simply;
It is not required to excavation foundation just and can be carried out reinforcing.Consolidation effect is easy to control, short time limit, and expense is low.
The comparison of strengthening of foundation distinct methods
Reinforcement means | Duration (day) | Expense (member) |
Increase bottom of foundation area method | 20~30 | 1000~1500 |
Grouting and reinforcing method | 15~20 | 600~1000 |
The method of the present invention | 5~10 | 400~700 |
Detailed description of the invention

Fig. 2 is the structural schematic diagram of anchor pole provided in an embodiment of the present invention;
In figure: 1, steel column;2, indoor reinforced concrete terrace;3, basic short column;4, ground beam;5, anchor pole.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
In the prior art, after steel-structure factory building installation photovoltaic panel, foundation bearing capacity is unsatisfactory for requiring.Prior art construction is numerous
It is trivial.It needs excavation foundation just and can be carried out reinforcing.It causes time-consuming and laborious.To solve the above problems, below with reference to concrete scheme to this hair
It is bright to be described in detail.
As depicted in figs. 1 and 2, new steel structure factory building foundation bracing means provided in an embodiment of the present invention includes: steel column
1, indoor reinforced concrete terrace 2, basic short column 3, ground beam 4, anchor pole 5.
Steel column 1 is mounted on basic short column 3, and ground beam 4 is poured in basic 3 top side of short column, and indoor reinforced concrete terrace 2 is left
