Embodiment Construction

[0066] Take a certain three types of construction projects as examples. Case 1 is that the garage of the building has two floors underground, and the main building has three floors underground. The foundation floor and roof of the garage are ultra-long structures, the thickness of the foundation floor is 500mm, the concrete strength is C30, and the impermeability grade is P8. The main building is located in the garage, the thickness of the raft is 600mm, the concrete strength is C30, and the impermeability grade is P8. The post-casting belts in the garage are criss-crossed irregularly, and the foundation floor alone exceeds 1183 meters. The on-site post-casting belt is divided into settlement post-casting belt and shrinkage post-casting belt. The settlement post-casting belt mainly prevents cracks from uneven settlement of the main building and garage during construction. The shrinkage post-casting belt mainly prevents temperature shrinkage cracks. The specific design overview...

Abstract

The invention discloses a construction method for canceling a settlement post-cast strip in jump warehouse operation. The construction method comprises the following specific implementation steps: 1,defining various conditions of a building field; 2, establishing a calculation model; 3, calculating settlement and a foundation internal force of each node; 4, performing collaborative calculation analysis step by step; 5, analyzing whether settlement meets a design requirement or not, and if not, carrying out foundation treatment; and 6, performing running water interval division on a construction section. According to the invention, the settlement of the building is calculated, and the settlement which does not meet the requirements is subjected to foundation treatment so that the sequential implementation of a subsequent jump warehouse method is ensured, and the design and construction requirements are met; a settlement post-cast strip is omitted, one-time casting forming is achieved,a later-period plugging procedure can be reduced, and a construction period can be shortened; the settlement post-cast strip is omitted, construction joints are reduced, the construction joints are convenient to clean, and an integral structure is formed as soon as possible; and in addition, a site space, the construction time and the construction cost can be greatly saved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for canceling the post-settlement pouring belt during warehouse jumping operations. Background technique [0002] The post-cast belt is to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven temperature, shrinkage, and settlement during construction. According to the code and structural force characteristics, the structure is temporarily divided into several parts. Part of the concrete belt is reserved at the corresponding positions of the foundation floor, wall, beam, etc. at the boundary and will not be poured temporarily during construction. After a period of time, the part of the concrete will be poured and tamped after the internal shrinkage or deformation of the components is completed, so as to connect the structure into a whole. temporary construction joints. The post-pouring tape is...
