Description
Technical field
The invention belongs to house wall strip footing technical fields, and in particular to a kind of side of strip footing local stiffening
Method.
Background technique
In Collapsible Loess District or other similar area, foundation soil chance water can occur to sink and lead to the feelings such as depression of bearing force
Condition, if useful water spot in these regional houses, water pipeline used all must necessarily be placed in buried pipe trench.As shown in Figure 1 and Figure 2,
When the trend of pipe trench needs to pass through wall, and pipe trench is more embedding than the strip footing of wall lower part also deep, former strip footing is generally all
It can be bypassed under pipe trench.As shown in figure 3, conventional way is downward according to the gradient staged of regulation within the scope of pipe trench two sides
Platform is put, until passing through until meeting basis from pipe trench lower part, to guarantee the continuity on basis.The drawbacks of this way, is to design
Expression is cumbersome, and layout design content is be easy to cause to omit；Construction will increase process, influence construction speed, and do not having
The section of foundation region of platform length is put enough, and the uniformity of basic stress should not also guarantee, influence superstructure to a certain extent
Using safe, therefore, it is necessary to a kind of new building method with solve the problems, such as presently, there are.
Summary of the invention
The present invention be directed to existing house strip footing local deepened technology there are the drawbacks of, design a kind of reduction construction
Range simultaneously deepens height according to different bases and takes corresponding constructing technology, when ensuring that strip footing chance pipe trench passes through,
It is able to maintain the uniform and stable characteristic of basic stress, provides good support for top building structure.
What the purpose of the present invention was achieved through the following technical solutions:
A kind of method of strip footing local stiffening, including pipe trench, wall, the pipe trench pass through wall, and in wall shape
The hole to be provided that pipe trench can be made to pass through at one, the hole bottom absolute altitude of the hole to be provided are lower than former strip footing absolute altitude, the original bar shaped
It is basic carry out downwards it is rectangular at new strip footing under local deepened to hole to be provided hole, and according to the difference of local deepened height H,
It is reinforced respectively using different support constructions between former strip footing and new strip footing in the two sides of hole to be provided, it is described
Support construction is branch bumping post or variable cross-section branch bumping post or doorframe column.

The top surface for stating hole to be provided is provided with lintel.
The cuboid mixes soil using reinforcing bar and pours.
The cylinder height of the cuboid=local deepened height H, the sectional dimension of cuboid are 250mmX original strip footing
Width.
The variable cross-section branch bumping post is made of two inverted trapezoidal cylinders, when 1000mm < local deepened height H≤1500mm
It is reinforced between former strip footing and new strip footing using variable cross-section branch bumping post；Two inverted trapezoidal cylinders are respectively set
In the two sides of hole to be provided, and respectively with former strip footing, new strip footing is vertical connect, and the top surface of the variable cross-section branch bumping post
Lintel is provided with the top surface of the either flush of former strip footing, the hole to be provided.
The inverted trapezoidal cylinder mixes soil using reinforcing bar and pours.
The height of the inverted trapezoidal cylinder=local deepened height H, the sectional dimension of inverted trapezoidal cylinder are 350~250mmX former
The width of strip footing.
The doorframe column is enclosed by five root long cubes, three face, and a root long cube is wherein provided at the top of hole to be provided,
The two sides of hole to be provided are each provided with two root long cubes；Local deepened height H > 1500mm Shi Yuan strip footing and new strip footing
Between reinforced using doorframe column.
The doorframe column encloses rectangular with new strip footing.
Long+the 250mmX2 of the length of cuboid at the top of the hole to be provided=hole to be provided, sectional dimension are 200~400mmX
The cuboid of thickness of wall body, hole to be provided two sides is made of upper half cuboid and lower half cuboid, the lower half cuboid
Height=local deepened height H, the sectional dimension of lower half cuboid is the width of 350~250mmX of side size original strip footing
Degree；Upper half cuboid height is distance of the top of lower our department's cuboid to doorframe column top, the section of upper half cuboid
Having a size of 250mmX thickness of wall body.
Beneficial effects of the present invention:
The present invention is when being detoured under pipe trench bottom according to current building construction strip footing, construction measure in design and
The problem of practice of construction process, is never asked in the basis connection of same absolute altitude and reinforcement measure with supporting and retaining system theory solution
Topic, this way that pipe trench is met for strip footing, simplifies design, facilitates construction, shortens the duration, has certain warp
Ji and social benefit.
