Description

Technical Field

[0001] The invention relates to the technical field of building foundation template construction, in particular to a large-volume building foundation template and a construction method. Background Art

[0002] Building foundation formwork, also known as building formwork, is a temporary support structure made according to design requirements to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct positions, and bear the weight of the building formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] The building formwork structure used in cast-in-place concrete structure construction mainly consists of three parts: panel, support structure and connectors. The panel is the load-bearing plate that directly contacts the newly poured concrete; the support structure is a temporary structure that supports the panel, concrete and construction load, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is the accessory that connects the panel and the support structure into a whole.

[0004] Building formwork is the formwork and support formed by concrete pouring. According to the nature of the material, it can be divided into building formwork, building wood plywood, film-faced plywood, multi-layer board, double-sided glue, double-sided film-faced building formwork, etc. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork, etc. according to the construction process conditions.

[0005] The modular steel formwork is a new type of "steel instead of wood" formwork in modern formwork technology, which has the advantages of strong versatility, easy assembly and disassembly, and a large turnover rate. It is used for cast-in-place reinforced concrete structure construction. It can be assembled into large-scale formworks of beams, columns, walls, and floor slabs according to design requirements in advance, and then hoisted into place as a whole. It can also be installed and disassembled in bulk.

[0006] In the prior art, a construction method for simply removing the bottom formwork of a foundation connecting beam is disclosed in publication number "CN116575709A". The method described in the present invention is used for construction. When removing the formwork, since the contact surfaces between the bottom formwork of the independent foundation connecting beam and the two sections of the bottom formwork of the foundation connecting beam on both sides are inclined surfaces, it is more convenient to remove the formwork, which can effectively reduce the time for removing the formwork. At the same time, the removal process is more labor-saving, avoids damage to the formwork due to violent removal, increases the repeated service life of the formwork, and is conducive to cost saving.

[0007] However, the existing technology still has major deficiencies, such as: In the above device and prior art: 1. Large-volume building formwork is heavy, and it is easy to shake when fixed by adsorption during the lifting and moving process, which may cause the large-volume building formwork to fall off; 2. Due to its heavy weight, it is difficult to ensure that the large-volume building formwork is installed in a vertical state and fits the side of the preset steel cage during installation, resulting in poor installation effect of the large-volume building formwork.

When the horizontal clamping arm 76 rotates to be parallel to the side of the building template, the second movable cylinder 72 is driven to drive the horizontal slider 74 to move to fit the side of the building template parallel to the building template, until the adjacent horizontal slider 74 drives the horizontal clamping arm 76 to complete the clamping and fixing of both sides of the building template, further ensuring the stability of the building template when it is adsorbed and locked; Before the building foundation formwork is vertically inserted into the side of the building steel cage for vertical installation, the extension arm 6 is driven by the vertical telescopic rod 52 to be vertically lowered. When the extension arm 6 is lowered to fit to the top of the building foundation formwork, the driving gear 62 is driven to rotate, and the driving gear 62 is engaged to drive the linear tooth plate 65 to move.
