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

Embodiment 1

[0042] like Figure 1 to Figure 3 As shown, the prefabricated module frame components: the surface of the prefabricated plate 3 (length 2850mm, width 1200mm, thickness 20mm) is attached with glass fiber mesh, the middle and top of the plate are provided with two pouring holes 4 with a diameter of 70mm, and the block connection key 2 ( Length, width 100mm, thickness 80mm) are delivered to the construction site after mass production in the factory assembly line using gypsum materials, and six connecting keys 2 and two prefabricated panels 3 are pasted firmly with adhesive to form a cavity mold, block positioning keys 1. Recycled hard plastic is used for mass production in the factory assembly line (trough section, length 200mm, width 80mm, 180mm, thickness 80mm, wall thickness 10mm). The force cable 9 is a closed loop fiber cable and a linear fiber cable (ringed at both ends) connected by a length adjusting device, or a nylon strap.

Embodiment 2

[0049] There are two columns of pull connection holes 7 on the prefabricated plate 3 (3 on one side, such as figure 1 shown), at the junction of the cavity mold (two-sided prefabricated panels 3 bonded to the connecting key 2), the prefabricated panels 3 on both sides (walls) The prefabricated panels 3) on the same side of the body are connected and fixed, and the rest are the same as in Embodiment 1.

Embodiment 3

[0051] On the prefabricated plate 3 of the cavity mold, drill two rows of six pull connection holes 7 in total on the spot, pass the pull connection holes 7 with a straight line applying force cable 9 or iron wire, and clamp the two sides with wooden cylindrical pins. The prefabricated panels 3 (prefabricated panels 3 on both sides of the wall) are pulled together to resist the tension during pouring, refer to Figure 12 . The rest are the same as Embodiment 1.

Abstract

The invention provides a self-balancing prefabricated surface and cast-in-place core filled wall formwork, which includes positioning keys (1) arranged at intervals along the direction of the filling wall, and the two sides of the positioning key (1) are connected by connecting keys (2). The prefabricated slab (3), the prefabricated slab (3) is provided with a tie hole (7). The middle and upper end of the prefabricated slab (3) has at least one pouring hole (4), and the outer side of the prefabricated slab (3) has a pressure device. The present invention has the advantages that: the materials for the formwork are prefabricated in batches in factories, the wall core material is low and the materials are widely used, and the logistics cost of materials is reduced. Wall prefabrication saves construction formwork, and cavity formwork saves external construction fixing measures, which simplifies the construction process. The prefabrication pressure is controllable and adjustable, and its comprehensive economic index and construction period are superior to the prior art, thereby making up for the deficiencies of the prior art.

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...
