Formwork of self-balancing prefabricated face and cast-in-situ core infilled wall

Abstract

The invention provides a formwork of a self-balancing prefabricated face and cast-in-situ core infilled wall. The formwork comprises positioning keys (1) arranged in the direction of an infilled wall body at intervals. The two sides of each positioning key (1) are prefabricated slabs (3) connected through connection keys (2), each prefabricated slab (3) is provided with a pulling connection hole (7), the middle and the upper end of each prefabricated slab are respectively provided with at least one pouring hole (4), and the outside of each prefabricated slab (3) is provided with a pressure applying device. The formwork has the advantages that materials used for the formwork are prefabricated in a large scale in a factory, requirements for core fillers of the wall body are low, the range of usable materials is wide, logistics cost of the materials is reduced, a construction formwork for wall face prefabrication is eliminated, external construction fixing measures of a cavity mold are eliminated, the construction process is simplified, prefabrication pressure is controllable and adjustable, the comprehensive economy index and the construction period of the formwork are superior to those of the prior art, and defects of the prior art are made up for.

Description

technical field [0001] The invention relates to a building filling wall, in particular to a self-balancing prefabricated surface and cast-in-place core filling wall formwork. Background technique [0002] The building filling wall is the maintenance structure of the building, with a large amount and a wide area. Its sound insulation, heat insulation, strength, fire prevention, moisture resistance, waterproof and other properties directly affect the use performance and safety performance of the building. With the progress of the times and the requirements of environmental protection, the era of Qin bricks and Han tiles has come to an end, and new wall materials have been introduced continuously. [0003] At present, aerated concrete blocks are mostly used as filling walls, and hollow inner mold metal mesh cement inner partition walls are also widely used. However, this type of filling wall has the following problems: First, with the shortage of human resources in our country...

Problems solved by technology

However, this type of filling wall has the following problems: First, with the shortage of human resources in our country, labor costs have doubled, logistics costs have continued to increase, and the cost of filling walls has increased significantly; secondly, traditional floors are generally 80 ~ The 100mm reinforced concrete thin slab has poor sound insulation and energy-saving performance, and cannot use any partition wall on it, which limits the flexibility of use; in addition, the low strength of the aerated concrete block filling wall is not conducive to safety And painting, its heavy weight will increase the cost of the main structure, its poor integrity is not conducive to the structure's earthquake resistance, and the construction process of the hollow inner mold metal mesh cement inner partition wall is complicated and the construction period is longer
