A framed infill wall

Abstract

A frame infill wall includes a steel mesh skeleton, which is formed by overlapping corrugated steel mesh in opposite directions to create a hollow mesh. Cement mortar layers are applied to both sides of the skeleton. The left and right ends of the skeleton are connected to embedded parts B within the main structural wall / column, and both sides are connected to the main structural wall / column via right-angled steel mesh. The upper end of the skeleton is connected to embedded parts C within the main structural beam / slab, with corresponding right-angled steel mesh on both sides. The lower end of the skeleton is connected to the main structural beam / slab via a cast-in-place cement mortar sill and embedded reinforcing bars. Vertical reinforcing bars are tied to both sides of the overlapping corrugated steel mesh sections, and horizontal distribution bars are tied to both sides of the skeleton. This frame infill wall incorporates vertical and horizontal reinforcing bars within the wall structure. The steel mesh skeleton joints at the wall edges are connected using steel mesh fencing, which improves the edge connection strength and reduces cracking of the cement mortar.

Description

Technical Field

[0001] This invention relates to the technical field of building infill walls, specifically a frame infill wall. Background Technology

[0002] Building infill walls are the structural components of buildings. With the rapid development of the construction industry, the use of non-load-bearing infill walls is increasing. Their sound insulation, heat insulation, strength, fire resistance, moisture resistance, and waterproofing properties directly affect the building's usability and safety. Therefore, selecting reliable and high-performance infill walls has become a key concern in the industry. Traditionally, lightweight bricks are used to construct infill walls, but their overall weight is still relatively heavy. Furthermore, many places currently use earthen bricks, which consume large amounts of soil. More importantly, brick firing requires a large amount of coal, causing air pollution. With the progress of the times and environmental protection requirements, the era of traditional bricks and tiles has ended, and new wall materials are constantly being introduced. To overcome the drawbacks of traditional wall construction methods, some infill walls use metal mesh panels as a foundation. Public literature also reports on some metal mesh panel infill walls, for example: 1. Chinese Patent: A Separable Wire Mesh Panel and its Wall Construction Method, Application Date: April 18, 2002, Application No.: 02111408.0, Abstract: This invention relates to buildings, and more particularly to a wall construction template composed of a wire mesh panel. The wall construction template comprises a zigzag wire mesh panel, an upper clamping member, and a lower clamping member. A separable wire mesh panel is located between the upper and lower clamping members, and the separable wire mesh panels, when combined, form a cement bond. The separable wire mesh panel has reinforcing bars. After the separable wire mesh panels are combined, a shotcrete operation is performed. This invention is not only convenient to transport, but also allows for easy integration with vertical joists; the separable wire mesh panel can also be easily clamped into vertical joists.

[0003] 2. Chinese Patent: An Internal Partition Wall Structure, Application No.: 201020552324.3, Application Date: 2010.09.30, Abstract: This utility model discloses an internal partition wall structure, which includes a keel and a wall fixed on the keel. The wall includes a first wave-shaped metal mesh, a second wave-shaped metal mesh, a filling layer, and a surface layer. The first and second wave-shaped metal meshes are closely joined at the center of the wall, and the two sides of the first and second wave-shaped metal meshes are the filling layers. The surface layer is on the outside of the filling layers. Therefore, the internal partition wall structure of this utility model is easy to construct. The tensile strength of polypropylene and wood fiber cement mortar and metal mesh improves the crack resistance and overall strength of the wall, and provides fire resistance. At the same time, the hollow space between the two wave-shaped metal meshes also improves the sound insulation effect of the wall. In addition, because the wave-shaped metal mesh is flexible, the internal partition wall structure of this utility model can be made into any curved shape.

Chinese Patent: An Environmentally Friendly Interior Partition Wall, Application No.: 201521104860.6, Application Date: 2015.12.28, Abstract: This utility model designs an environmentally friendly interior partition wall, including a frame. The frame is composed of triangular iron bars, and a wire mesh is installed on the frame. The wire mesh is fixedly connected to the frame by connectors. The connectors consist of U-shaped connectors with external threads at both ends and nuts. The U-shaped connectors pass through mounting holes on the wire mesh and mounting holes on the frame and are fixed by nuts. The cross-section of the straw board is wavy or trapezoidal. Advantages of this utility model: simple construction, low cost, light weight, reduced soil consumption, and reduced air pollution caused by brick firing.

[0005] 4. Chinese Patent: Hollow Inner Membrane Metal Mesh Cement Internal Partition Wall Structure, Application No.: 202220539057.9, Application Date: 2022.03.14, Abstract: Hollow Inner Membrane Metal Mesh Cement Internal Partition Wall Structure, relating to the installation structure of hollow inner membrane metal mesh cement internal partition walls on indoor floors. A wall base is poured on the building floor slab; a supporting steel plate is set on the wall base, and the bottom of the supporting steel plate is connected to the wall base by building sealant; a hollow inner membrane metal mesh is set on the supporting steel plate, and fixing parts A are set at equal intervals below the hollow inner membrane metal mesh, and the channel-shaped keel at the bottom of the hollow inner membrane metal mesh is embedded in the frame of the fixing part A; a fixing part B is set on each side of each fixing part A, and the connecting plate of the fixing part B is attached to the side of the fixing part A, and the overlapping part of the connecting plate and the fixing part A is connected by self-tapping screws. It solves the problem that the existing hollow inner mold metal mesh cement partition wall bottom structure cannot guarantee the straightness of the hollow inner mold metal mesh, and that there are gaps between the bottom of the wall and the ground, which can also cause water seepage.

[0006] Application research has revealed that although many publications report on infill walls made of metal mesh panels, the walls are prone to cracking in practical applications, especially around the perimeter of the infill wall and around doors and windows. This results in high maintenance costs, making it difficult for hollow inner mold metal mesh cement infill walls to be widely promoted and applied. Summary of the Invention

[0007] The purpose of this invention is to address the problems existing in the prior art by providing a frame infill wall. This frame infill wall, with vertical reinforcing bars and horizontal distribution bars arranged in the wall body, can prevent the steel mesh skeleton from buckling under weight when the cement mortar plaster is not dry, thereby limiting the width of horizontal cracks; it can reduce the width of horizontal cracks caused by drying shrinkage, temperature shrinkage, or creep of cement mortar; and the steel mesh enclosure around the steel mesh skeleton of the infill wall is used to improve the connection strength around the wall body and reduce the cracking of cement mortar.

The opening of the perforated channel steel at the concrete vertical frame of the doorway faces the doorway, and the opening of the perforated channel steel at the concrete lintel of the doorway faces away from the doorway.

The steel mesh frame has a doorway, and the doorway has a doorway structural column extending to the top. The doorway structural column contains doorway structural column reinforcement bars, which are positioned vertically and horizontally.

The bottom horizontal concrete frame reinforcement within the bottom horizontal frame is welded to the window opening's vertical reinforcement. The external enclosure of the window opening's vertical concrete frame, the window opening's concrete lintel, and the bottom horizontal concrete frame has perforated channel steel. The openings of the perforated channel steel at the window opening's vertical and bottom horizontal frames face the window opening, while the openings of the perforated channel steel at the window opening's concrete lintel face away from the window opening. Vertical reinforcing bars are inserted into the perforated channel steel. The perforated channel steel is tied to the adjacent steel mesh frame.

The two ends of the concrete lintels for the window openings are connected to the structural main walls / columns at both ends via horizontal tie beams. Horizontal tie beam reinforcement is provided within the horizontal tie beams. One end of the horizontal tie beam reinforcement is connected via embedded parts A set in the structural main walls / columns, and the other end is connected to the reinforcement of the concrete lintels for the window openings. The outer enclosure of the horizontal tie beams consists of perforated channel steel with the openings facing upwards.

[0013] A further preferred embodiment: The embedded part A includes a steel plate, one side of which is welded with reinforcing bars for extending into the main structural wall / column, and the other side of the steel plate is welded to the horizontal tie beam reinforcement.

[0014] Further preferred configuration: When the frame infill wall has window openings, or is relatively long (≥5 meters or ≥2 times the wall height), or relatively high (≥4 meters), it is composed of 2 or more steel plate mesh frames + reinforced concrete components (including reinforced concrete structural columns, horizontal frames, lintels, etc.; the setting of the reinforced concrete structural columns refers to the corresponding regulations for setting such components in frame masonry infill walls).

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages: 1. Placing vertical reinforcing bars and horizontal distribution bars in the wall can prevent the steel mesh skeleton from buckling under weight when the cement mortar plaster is not dry, thereby limiting the width of horizontal cracks; it can also reduce the width of horizontal cracks caused by drying shrinkage, temperature shrinkage or creep of cement mortar.

[0019] 2. Steel mesh fencing is used around the steel mesh frame of the infill wall to improve the connection strength around the wall and reduce cracking of cement mortar.

[0020] 3. Combine the reinforced concrete vertical frame of the door and window openings with the reinforcement of the reinforced concrete lintel to form a "U" reinforcement; this greatly reduces the trouble of anchoring these two types of reinforcement separately.

[0021] 4. Embedded part B uses steel pipes to anchor the reinforcing bars instead of embedded parts, and is used for inserting the ends of horizontal distribution bars with anchoring adhesive; it solves the problem of not being able to anchor reinforcing bars on embedded parts.

[0022] 5. Perforated channel steel is used to replace formwork in reinforced concrete members; it replaces stirrups or distribution bars to fix the main reinforcement; and its transition allows for reliable bonding between concrete and cement mortar plaster.

[0023] 6. Lintel reinforcement is distributed at the top and bottom of door and window openings, and reliably tied to the steel mesh frame using wire ties; this greatly reduces the width of diagonal cracks that easily occur at the corners of door and window openings. Reinforced concrete frames (including horizontal and vertical reinforced concrete frames; horizontal reinforced concrete frames at the bottom of window openings; vertical reinforced concrete frames on the sides of smaller door and window openings (width < 2.1 meters)) reduce the adverse effects of door and window openings on the overall integrity of the wall, thus limiting crack width. Reinforced concrete structural columns are placed on the sides of larger door and window openings (width ≥ 2.1 meters); and in the middle of longer walls (≥ 5000 mm or ≥ 2 times the wall height), greatly reducing the adverse effects of large openings and long walls on the overall integrity of the wall, thus limiting crack width.

[0024] 7. When reinforced concrete horizontal tie beams are set in the middle of the wall (height) of the door and window openings, they greatly reduce the adverse effects of wall height on the integrity of the wall, thereby limiting the width of cracks. Attached Figure Description
