Embodiment 1

[0029] Embodiment 1, the present invention discloses a construction method of a building jacking steel concrete support system, the steel concrete support system is a steel concrete shear wall or a steel concrete frame structure, specifically comprising the following steps:

[0030] Step 1: Construction of the lower support structure 1 and pallets at the bottom of the building; Step 1 includes (1) Foundation treatment: reinforce the foundation around the building and set up lower support points; (2) Rigid pallet construction: use artificial shield reinforcement The concrete box girder method is used to make rigid pallets at the bottom of the building; (3) Construction of the end support beams: the end support beams are poured at both ends of the reinforced concrete box girder. For the bottom treatment method, please refer to the applicant's previous application number 201210184152.2 Invention patent application.

[0031] Step 2: Lift the building (see attached Figure 1-6 ), ...

Embodiment 2

[0033] Embodiment 2, see attached Figure 7 The difference between this embodiment and Embodiment 1 lies in the lower support system structure. The lower support system involved in this embodiment is a steel concrete frame structure, which includes binding column steel bars around the columnar structure formed by permanent section steel pads, and installing formwork After the completion, the column concrete is poured, and a steel connecting beam is set between two adjacent columns to strengthen the structural strength.

[0034] To sum up, taking advantage of the complementary advantages of strong concrete stability, high rigidity and high compressive strength, quick manufacture, and precise shape of the steel block, the lower support system of the jacked-up building is set as a steel-concrete structure, which improves the lifting of the building. The height and construction speed, on the one hand, can shorten the construction period and reduce the use of engineering materials....

Abstract

The invention discloses a construction method of a building jacking steel reinforced concrete supporting system, and relates to the technical field of building jacking construction. The construction method includes the four steps of construction of a lower portion supporting structure and a building bottom tray, building jacking, positioning of profile steel cushion blocks, and construction of a steel reinforced concrete shear wall or a steel reinforced concrete frame structure. The construction method has the advantages that a concrete foundation on the bottom of a building is designed to be of the shear wall or frame structure, complementary advantages that concrete is strong in stability and large in rigidity and the profile steel cushion blocks are high in compressive strength, fast and convenient to manufacture, and accurate in appearance are utilized, the supporting system jacking the bottom of the building is designed to be of a profile steel concrete structure, and thus the jacking height and the construction speed of the building are improved; on one hand, construction periods can be shortened, and using of engineering materials is reduced; on the other hand, input of manpower cost can be reduced, and engineering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building jacking construction, in particular to a construction method of a building jacking steel concrete support system. Background technique [0002] For the jacking protection of existing buildings (structures), the importance of the lower support system as a force transmission system between the upper structure and the foundation is self-evident. [0003] There are two types of support systems for existing jacking projects: steel support systems and concrete support systems. The production speed of the section steel support system pad is fast, the jacking point bears high pressure, and the production is precise, but the jacking height is small, and a large number of lateral stable supports need to be installed in the support system; The speed is slow and the lifting cycle is long. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a constr...
