Problems solved by technology

[0003] The above traditional technical solutions have limitations in actual construction. For example, when it is necessary to replace the hidden corner columns, due to the influence of the space position, it is impossible to add reinforced concrete columns or steel supports, so the replacement cannot be completed. In serious cases, the building needs to be replaced. Things need to be dismantled and rebuilt, which makes the cost of entrustment larger

Abstract

The invention discloses a steel tray supporting force transferring system, which comprises an upper steel tray assembly, a lower steel tray assembly and support assemblies, wherein the upper steel tray assembly is used for bearing a load above a target building member; the lower steel tray assembly is used for transferring the load above the target building member to a lower building; the support assemblies are arranged between the upper steel tray assembly and the lower steel tray assembly, and are used for transferring the load above the target building member borne by the upper steel tray assembly to the lower steel tray assembly; the upper steel ray assembly comprises a plurality of upper steel beams; the lower steel tray assembly is correspondingly provided with a plurality of lower steel beams one by one; and the upper steel beams and the lower steel beams are I-shaped steel beams or channel steel beams or combined steel beams. The steel tray supporting force transferring system has the advantages of convenience in underpinning, replacing or lifting and rectifying the target building member, high supporting stability, safety, reliability, low space occupation, convenience in installing and using, flexible selection of underpinned components, detachability for repeated use, and reduction in the construction cost.

Description

Technical field [0001] The invention relates to the technical field of underpinning / replacement of buildings, in particular to a steel pallet supporting force transmission system. Background technique [0002] When a column or shear wall concrete needs to be replaced, the traditional method in the prior art is to build a new reinforced concrete column support next to the column or shear wall that needs to be replaced or replaced, or use a large-area steel tube support. This new method of making reinforced concrete column supports takes a long time and increases the point load. This method is not recommended in actual projects; if large-area steel pipe supports are used, due to the different holding forces of each support point, it will produce Uniform supporting force causes safety hazards and takes up a lot of space, which affects construction. [0003] These traditional technical solutions have limitations in actual construction. For example, when the corner concealed column nee...
