Description

Technical Field

[0001] The utility model relates to the field of building structures, and particularly to a purlin-free wall system. Background Art

[0002] In the prefabricated metal steel structure building wall enclosure system, the metal sandwich panel wall system is increasingly applied to the exterior walls of buildings. In order to respond to the social demand for energy conservation and emission reduction, in modern engineering projects, the requirements for building material conservation and energy conservation are also getting higher and higher.

[0003] At present, most of the installations of metal steel structure wall sandwich panels adopt the structure of horizontal main purlins plus vertical secondary purlins on the wall. The horizontal main purlins are connected to the purlin support plates on the flange plates of steel columns through ordinary bolts. The vertical secondary purlins for fixing the sandwich panels are installed between two horizontal main purlins. The wall sandwich panels are then fixed to the relatively thin vertical secondary purlins through self-tapping screws. This connection structure form requires a large amount of materials for the wall purlins, the construction method is slow, the connection and fixing effect is not reliable enough, and during the installation of metal wall panels, the assembly error is large, which is easy to cause material waste and increases the construction cost of the project.

[0004] In the patent "A New Type of Purlin-free Wall Composite Panel Structure System" (Patent No.: CN214462075U), a new type of purlin-free installation method is proposed. The staggered installation of horizontal main purlins and vertical secondary purlins is cancelled. Through the keel connecting angle steel welded on the structural column, the C-shaped vertical keel is fixed on the structural column through lateral installation structure nails. The sandwich panel is connected to the C-shaped vertical keel fixed on the structural column at the end through the structural long nails penetrating the sandwich panel surface, and the joint decoration edge is used to decorate the joint of the sandwich panel to cover the outer end of the structural long nails.

[0005] In the above method, a keel and angle steel connection structure needs to be applied to fix the sandwich panel on the structural column, consuming a large amount of building materials; there are many connectors, which are prone to cause structural instability; applying structural long nails to fix the sandwich panel requires penetrating the sandwich panel and the keel, with a certain installation difficulty, and problems are likely to occur when penetrating the keel. Summary of the Utility Model

[0006] In view of the above deficiencies in the current technology, the utility model provides a purlin-free wall system, which can reduce the consumption of building materials and ensure the wall strength.

[0007] To achieve the above object, the embodiments of the utility model adopt the following technical solutions:

[0008] A purlin - free wall system, comprising structural columns, composite wall panels and connectors. The composite wall panels are fixed on the structural columns through the connectors. Flanges are provided on the structural columns, and first fixing holes are provided on the flanges. The cross - section of the connector is right - angled. A second fixing hole is provided on the first side of the connector, and a third fixing hole is provided on the second side of the connector. A number of keels are arranged inside the composite wall panels, and the keels protrude at both ends of the composite wall panels. The composite wall panels are connected and fixed through the ends of the keels and the connectors by using the second fixing holes. The connectors and the flanges of the structural columns are connected and fixed by using fasteners through the first fixing holes and the third fixing holes.

[0009] According to one aspect of the present invention, a number of keels inside the composite wall panels are arranged at intervals in the vertical direction.

[0010] According to one aspect of the present invention, clamping parts that can be cooperatively clamped are respectively provided at the bottom and the top of the composite wall panels, so that adjacent upper and lower composite wall panels are clamped.

[0011] According to one aspect of the present invention, the composite wall panel is a metal sandwich panel, with gaps provided inside, and the gaps are filled with filling materials.

[0012] According to one aspect of the present invention, the composite wall panels are connected and fixed through the ends of the keels and the connectors by using the second fixing holes, and the fixing method used is welding fixation.

[0013] According to one aspect of the present invention, the structural column is an I - shaped steel column.

[0014] According to one aspect of the present invention, the second fixing hole is elongated, and the keel is a light steel strip.

[0015] According to one aspect of the present invention, the connectors and the flanges of the structural columns are connected and fixed by using fasteners through the first fixing holes and the third fixing holes, and the fasteners used are bolts.

[0016] According to one aspect of the present invention, the purlin - free wall system further includes a joint decorative cover plate.

[0017] According to one aspect of the present invention, the joint decorative cover plate is fixed to the joint of two - span composite wall panels through structural nails.

[0018] Advantages of the implementation of the present utility model:

[0019] For the technical solution provided by the present utility model, there are keels inside the composite wall panels, and the keels and the steel columns are installed and fixed through connectors. The system structure is simple, the components to be used are further streamlined, and it is easier to install and construct than the existing technology.

[0020] There is no purlin support plate on the steel column, which reduces the steel consumption. During the production process of the steel column, there is no need for manual welding, reducing the material consumption in the production of the steel column and the labor cost.

[0021] The wall does not use purlins, saving 30% of the workload in the construction of the wall enclosure. It can effectively reduce the labor cost, speed up the construction progress, greatly reduce the project cost, and make the interior of the building more beautiful.

[0022] The composite wall panel is internally provided with light steel keels. On the one hand, it can replace the purlins to ensure the strength of the wall system; on the other hand, the keels are built inside the composite wall panel, which can ensure the flatness of the wall panel and improve the external beauty of the building.

[0023] During factory production, first produce the composite wall panel with built-in light steel keels, and then the connectors can be directly welded to the keels of the composite wall panel. In this way, when installing the wall panel during construction, only need to fix the connectors and the steel column with bolts, which can greatly reduce the workload during the installation of the wall panel, reduce the labor cost, and improve the work efficiency.
