Embodiment Construction
[0044] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0045] see figure 1 , Figure 4 , the construction structure for underpinning the load-bearing wall 10 in this embodiment is used to underpin the load-bearing wall 10 located below the floor 8 into a frame load-bearing structure composed of frame column assemblies and beams 6 connected, mainly including frame column assemblies , more than two beam support positions 2, more than two beam support members 3, beam casting molds and concrete pouring holes 5.
[0046] Wherein, the frame column assembly includes more than two frame columns 1 , and the two or more frame columns 1 are respectively supported at two or more bearing points 7 below the floor 8 for supporting the weight of the floor 8 . like Figure 7 Shown is a schematic diagram of 8 load-bea...

The invention discloses a construction structure and method used for underpinning a load-bearing wall. The construction structure and method are used for underpinning the load-bearing wall located below a floor into a frame load-bearing structure. The construction structure comprises a frame column assembly, two or more beam supporting positions, two or more beam supporting pieces, a beam pouring die and concrete pouring holes, wherein the frame column assembly is arranged at the bearing point position on the lower portion of the floor in a supporting mode, the beam supporting positions are arranged in the load-bearing wall in chiseled mode, are tightly adjacent to the lower portion of the floor and are arranged in the length direction of a beam in a dispersed mode, the beam supporting pieces are arranged at the beam supporting positions in a clamped mode, and the concrete pouring holes are formed between the two beam supporting pieces and enable the upper portion of a containing cavity of the beam pouring die to be communicated with the outside. The method comprises the steps that the frame column assembly is arranged, the beam supporting positions are arranged in the chiseled mode, the beam supporting pieces are arranged, a beam position wall is disassembled, the beam pouring die is installed, the concrete pouring holes are formed and the beam is poured. When the construction structure and method are used, a large number of temporary supports do no need to be arranged near the load-bearing wall, construction procedures are reduced, the construction time is saved and the cost is reduced.
Description
technical field [0001] The invention relates to the field of building construction transformation, in particular to a construction structure and construction method for underpinning a load-bearing wall. Background technique [0002] With the development of social economy and culture, people's requirements for living and working environments have also increased, especially for building space and functions, so that a considerable number of old buildings can no longer be used. To meet the needs of people at the present stage, reinforcement design and transformation must be carried out. For example, it is required to transform the original small office or dormitory into a restaurant or meeting room with a large space. [0003] The structural forms of existing old buildings are mostly brick-concrete structures, and the reinforcement and renovation generally involve the removal of load-bearing walls and the use of underpinning beams to bear the loads on the original walls. The bi...
