Description

Double-layer composite slat cast-in-place inner partition wall structure

technical field

The invention relates to a cast-in-place interior partition wall structure, in particular to a cast-in-place interior partition wall structure with double-layer composite slats using keel components. the

Background technique

With the continuous acceleration of urbanization and the continuous improvement of construction technology, more and more high-rise long-span structures are used in people's work and life. It has good thermal insulation and energy-saving effects, but it is not conducive to the implementation of industrialized production and green construction due to its shortcomings such as heavy weight, poor tensile, bending, and shear properties, and the need for mortar masonry on site, which is time-consuming and labor-intensive. In order to solve the problems existing in the masonry structure, building interior partition walls with light-weight assembled interior partition walls as the main wall system have emerged in the market. the

Lightweight prefabricated interior partition wall refers to the residential or public building interior partition wall system that uses light slats to be processed and prefabricated in the factory and then transported to the construction site, and then assembled and other measures are taken. At present, the lightweight prefabricated interior partition wall system mainly adopts the skeleton partition wall, which has been widely used in various aspects of the construction industry due to its industrial production and easy installation, but many problems have been exposed during the use process, mainly It is manifested in the following aspects:

1. Since the keel of the skeleton partition wall adopts a U-shaped steel frame, multiple closed spaces are formed between the panels after installation, and each steel frame is an independent and unconnected space, which makes it necessary to install on the panels of each space. The grouting holes are all started, the construction is inconvenient, and when the concrete is filled, the operator will not find it immediately, and it is easy to make the grout or swell between the panel joints on both sides. the

2. Due to the light and thin steel frame used by the keel, when the panel is installed on the steel frame by nailing, it cannot be fixed well, making it difficult to guarantee the stability of the entire skeleton partition wall. the

3. Because the lightweight partition board is installed in the non-load-bearing part of the building, the required installation parts are places with large spans, the largest settlement deformation, and the weakest load resistance. Due to the particularity of smoothness, it is easy to cause cracks at the joints between panels and doors and windows. When concentrated loads will cause vibration and deformation of light wall panels, cracks and hollowing will occur. the

Contents of the invention

The object of the present invention is to overcome the defects of the prior art, and provide a double-layer composite lath cast-in-place inner partition wall structure with convenient construction, high stability and good seismic performance. the

The technical scheme that realizes the above-mentioned purpose is:

A double-layer composite slat cast-in-place internal partition wall structure of the present invention includes a keel assembly and panels installed on both sides of the keel assembly; lightweight foam concrete is injected between the panels to form the internal partition wall; the The keel assembly includes a pair of keels and a plurality of connecting plates, the keels are fixedly connected to the panel on this side, and the keels are connected through the connecting plates to form gaps. the

The above technical scheme greatly improves the stability of the inner partition wall structure due to the adoption of the keel assembly. There is a gap between the keels, so that a connected space is formed between the panels on both sides. When injecting lightweight foam concrete between the panels, only one grouting hole is required, which is convenient for construction and can effectively shorten the construction period. the

A further improvement of the present invention is that: the keel is a hollow frame inside, and light concrete is poured into the frame. The keel in the keel assembly is a frame with a light concrete structure. This design can effectively improve the rigidity and stability of the keel assembly. the

A further improvement of the present invention lies in that the screws penetrate through the frames of the panel and the keel, and penetrate into the light concrete in the frame so as to securely connect the keel and the panel. The light concrete in the keel frame can effectively fix the screws. Compared with the keel frame in the prior art, the light and thin side panels are not enough to fix the screws. The technical solution adopted in the present invention can effectively solve the deformation of the inner partition wall due to extrusion And other issues. the

A further improvement of the present invention lies in that: a grouting hole and an overflow hole are respectively provided at both ends of the top of the panel. Because there is a gap formed between the keels, the gap between the panels is connected, and only one grouting hole is required. Another overflow hole is used to remove air between the panels and also acts as a cue for the lightweight foam concrete to fill. the

The further improvement of the present invention lies in that: a reinforcing formwork is installed on the outer side of the panel. In order to make the inner partition wall more stable, a layer of reinforcement formwork can be added on the outer layer of the panel. the

The invention also has the advantages of light weight, low construction cost, good thermal insulation performance, high flame retardant performance, good sound insulation effect, high shock resistance performance, good vibration isolation effect, and short construction period. the
