Abstract
The invention relates to a frame type combined support-replacing system and a construction method thereof. The frame type combined support-replacing system comprises lattice columns, supports, a main body structure and replacing supports, wherein the replacing supports are respectively arranged below the original supports, thereby forming a frame type combined replacing support. The frame type combined support-replacing system is a novel support-replacing system in which the newly-built replacing supports are combined with the original part of supports to form the frame type combined support to together resist a structural lateral force. The frame type combined support-replacing system utilizes the original part of supports, thereby not only reducing the construction workload of the newly-built supports and also saving the construction period for removing the original supports. The original supports and the newly-built supports bear force in a combined manner, so that the rigidity and the stability of the replacing supports are further increased.
Description
Technical field
The present invention relates to a kind of frame type combination support replacement system and job practices, especially a kind of support replacement job practices that is applicable to that the underground large spatial structure in core city is built.
Background technology
When descending structure construction routinely,, only can satisfy the support replacement requirement at corresponding site construction reinforced bar concrete beam or section steel beam because of floor lacks less, spatial extent is little.In underground large spatial structure construction; structure floor disappearance area is big, the disappearance number of plies is many, spatial extent is big; common beam type support replacement all is difficult to guarantee the reasonable stressed and construction safety of support replacement from intensity, rigidity and stable equal angles, and trouble, construction period prolongation but also cost are high if the multiple tracks beam type support replacement of constructing is not only constructed.Support replacement belongs to temporary support structure, if can adopt novel support replacement system, guaranteeing prerequisite decline low cost, the quickening progress of construction safety, then can create good economic benefit.
Summary of the invention
The present invention will solve the underground large spatial structure construction stage, can't satisfy the technical problem of construction requirement because of original beam type support replacement, the job practices of a kind of frame type combination support replacement system is provided, and the support replacement system that this system has sufficient intensity, rigidity and stability guarantees that underground structure can resist the lateral force that water and soil applies voluntarily at fininshing step not.
Technical scheme of the present invention is: a kind of frame type combination support replacement system comprises lattice column 1; Support 2; Agent structure 4, support replacement 3 is provided with support replacement 3 respectively below original support 2, form frame type combination support replacement.
A kind of job practices of frame type combination support replacement system the steps include:
1) below original support 2, agent structure 4 floor absolute altitude places, newly-built support replacement 3;
2) during the foundation ditch supporting removal, keep the support 2 that is positioned at the large space zone;
3) repeating step 1) and step 2), until forming frame type combination support replacement.
The invention has the beneficial effects as follows:
Frame type combination support replacement system is that a kind of newly-built support replacement supports the novel support replacement system that formation frame type combined support is resisted the structure lateral force jointly in conjunction with original part.It has utilized original part to support, not only reduced newly-built support construction working amount, but also saved original supporting removal construction period.Original support combines stressed with newly-built support, increased the rigidity and the stability of support replacement again.
The frame type combined support has increased the rigidity and the stability of support replacement system, more reasonable stress greatly; Reserve part supports the construction period shortened supporting removal, when constituting support replacement system a part of, can save the time and the cost of support replacement construction again, has extraordinary economic benefit.

The specific embodiment
Below in conjunction with specific embodiment, further set forth embodiments of the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, frame type combination support replacement system comprises lattice column 1; Support 2; Agent structure 4, support replacement 3.Support replacement 3 is set respectively below original support 2, forms frame type combination support replacement.
To shown in Figure 5, the construction sequence of frame type combination support replacement system is as follows as Fig. 2:
(1) below original support 2, agent structure 4 floor absolute altitude places, newly-built support replacement 3 (Fig. 2);
(2) during the foundation ditch supporting removal, keep the support 2 (Fig. 3) that is positioned at the large space zone;
(3) repeating step one and step 2 are until forming frame type combination support replacement (Fig. 4,5).
Claims (2)
1. a frame type combination support replacement system comprises lattice column (1), supports (2), and agent structure (4) is characterized in that: in the below of original support (2) support replacement (3) is set respectively, forms frame type combination support replacement.
2. the job practices of a frame type combination support replacement system is characterized in that, the steps include:
1) in the below of original support (2), agent structure (4) floor absolute altitude place, newly-built support replacement (3);
2) during the foundation ditch supporting removal, keep the support (2) that is positioned at the large space zone;
3) repeating step 1) and step 2), until forming frame type combination support replacement.
