Description
Technical field
The present invention relates to building field, specifically a kind of method that stake in the underground space is transform as to post.
Background technology
In conventional building field, the definition of post is mainly to bear axial compression, is used for supporting superstructure and load is reached to basic vertical straight-bar; The definition of stake is to bear pile top load by frictional resistance and end resistance, and the load bearing is delivered to the vertical straight-bar in foundation soil (or basement rock).Because stake and post have two diverse function settings, be difficult to change and transformation always.
Yet in the process of the following newly-built underground space of existed building, the needs due to design and bearing capacity, be transformed into post by stake, to reach the design standard of the underground space.
Summary of the invention
The object of the invention is to overcome the deficiency in above-mentioned background technology, a kind of method that stake is transform as to the post in support underground space is provided, the method should have that transformation speed is fast, construction is simple, fast, the effective feature of moulding.
Technical scheme provided by the invention is: a kind of method that stake in the underground space is transform as to post, according to following steps, carry out:
1) first the upper face of stake is cleared up;
2) choose two semicircular ring shaped steel cylinders of adapting of diameter with stake, be wrapped in the upper face of stake, make stake in two semicircular ring shaped steel Tong centers;
3) binding site between two semicircular ring shaped steel cylinders carries out electric welding field, makes two semicircular ring shaped steel cylinders be welded to each other into an integral body and stake is wrapped in wherein firmly;
4) place to be welded cooling after, the gap between stake and semicircular ring shaped steel cylinder is filled up with concrete or grouting material, become post.
The inside diameter of described semicircular ring shaped steel cylinder is larger than the outer dia of stake.
Stake in the underground space is transform as to a method for post, according to following steps, carries out:
1) first the exposed surface of stake is cleared up;
2) at the peripheral assembling reinforcement cage of clearing up position, and set up template;
3) concreting or grouting material in template, make it to be solidified as securely one with reinforcing cage and stake;
4) when concrete curing moulding reaches due intensity, stripping; Become post.
Described cleaning is that loosening float stone and the dust of the upper face of stake is removed clean.
Operating principle of the present invention is: stake is mainly at axis direction pressurized, and is embedded in the soil body; In being exposed to space, when post is used, be mainly whole stressed, shearing resistance etc.; Therefore need to carry out overstriking reinforcing, increase shearing resistance and whole stress-bearing capability, enable to bear the Integral Loading of beam slab,
The invention has the beneficial effects as follows:
The present invention by the exposed position of stake is around made steel cylinder or stake around assembling reinforcement cage set up template concreting, make stake there is the bearing capacity of post, thereby stake be transformed into post.Can when building is built the underground space below, gather materials on the spot, the stake originally just with certain bearing capacity is transformed into post, reduced the quantity of newly-built post, guaranteed that the underground space do not cave in, and underground space bearing capacity meets the requirements; The method has reduced material consumption, has saved artificial input, has also accelerated project construction progress.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of one of embodiment of the present invention.
Fig. 2 is the attached TV structure schematic diagram of one of embodiment of the present invention.
The specific embodiment
Below in conjunction with embodiment shown in the drawings, further illustrate.
In the digging process carrying out for the following newly-built underground space (as underground parking, basement etc.) of existed building, the stake being embedded in the soil body 5 reveals gradually, according to conventional way, these exposed part all need to be removed.Yet building the underground space needs again many posts to support.For Accelerating The Construction progress, reduction construction cost, inventor determines to transform the stake in the underground space as post; Specifically can be divided into following two kinds of methods;
In embodiment shown in Fig. 1, adaptation step is as follows:
1) first the exposed surface of stake 1 is cleared up, the loosening float stone of the exposed surface of stake and dust are removed clean.
2) choose two semicircular ring shaped steel cylinders 2 mutually suitable with the diameter of stake, be wrapped in the position after cleaning, make stake in two semicircular ring shaped steel Tong centers; The inside diameter of semicircular ring shaped steel cylinder is larger than the outer dia of stake, conventionally should be greater than 2-5cm, is beneficial to concreting or grouting material.The length (axial length) of semicircular ring shaped steel cylinder is according to the height at exposed position (or determining as required).
3) binding site between two semicircular ring shaped steel cylinders 3 carries out electric welding field, makes two semicircular ring shaped steel cylinders be welded to each other into an integral body and stake is wrapped in wherein firmly;
4) place to be welded cooling after, gap 4 use concrete or grouting material between stake and semicircular ring shaped steel cylinder are filled up.
Another kind of by the method for the stake change post in the underground space, according to following steps, carry out (view omission):
1) first the exposed surface of stake is cleared up;
2) according to the size of stake, and the requirement of load bearing capacity, the peripheral assembling reinforcement cage at cleaning position, and set up template;
3) in template, concreting or grouting material make it to be solidified as securely one with reinforcing cage;
4) when concrete curing moulding reaches due intensity, stripping; Stake becomes post.After above-mentioned transformation task is complete, the post that these transformations form just can have been born support task.
