Description

Technical Field

[0001] This article belongs to the field of building installation technology, specifically involving wall support structures, which is an adjustable single-door type support. Background Technology

[0002] Wall support structures are key components in building installation, directly affecting construction safety and efficiency. They are mainly used to support objects that need to protrude from the wall, ensuring secure installation and preventing detachment or deformation. They must also be adaptable to different wall materials such as concrete and brick walls, providing reliable anchoring force. Modular design and detachable and adjustable features facilitate later maintenance and modification, meeting long-term use needs.

[0003] Existing wall support structures generally suffer from technical defects. Traditional supports often adopt fixed-angle designs or only support adjustment in one direction, making it difficult to meet the installation requirements under complex working conditions. They often require the use of additional shims or on-site cutting and adjustment, which significantly increases construction time. The design of fixed bolt holes is prone to loosening of the connection parts due to uneven walls or component tolerances, requiring frequent reinforcement. Multi-component splicing support structures not only increase production and installation costs, but their customized nature also leads to poor versatility of special components such as curtain wall supports. Existing support systems require repeated measurement, drilling, and adjustment during installation, which is extremely inconvenient for high-altitude operations. Multiple people are usually needed to complete the adjustment of horizontal and verticality, which greatly reduces construction efficiency. Utility Model Content

[0004] To address the common technical deficiencies in existing wall support structures, this paper proposes an adjustable single-door type support, hereinafter referred to as the adjustable support. Through structural optimization design and the application of new materials, this support has achieved significant improvements in multi-dimensional adjustment performance, ease of installation, structural stability, and environmental adaptability.

[0005] An adjustable single-door bracket can be wall-mounted on a load-bearing wall. The bracket mainly consists of bracket connectors, vertical brackets, bolts, horizontal brackets, bracket fixing parts, and expansion bolts. The bracket connectors adopt a purlin-type structure, bent from the middle to form two parts: a side surface and a bottom surface. The side surface has a bolt hole at its vertical center, and the bottom surface has two sides bent upwards to form grooves, with a bolt hole at its horizontal center. Each bracket set contains two identical bracket connectors arranged symmetrically. The vertical bracket is a purlin-type structure with a vertically arranged array of bolt holes on its back. The horizontal bracket also adopts a purlin-type structure with a horizontally arranged array of bolt holes on its back. Each set of brackets contains two identical horizontal brackets arranged symmetrically. The bottom grooves of the two bracket connectors are connected to the back ends of the vertical brackets. The top grooves of the two bracket connectors are connected to the front grooves of the two horizontal brackets. The bracket fixing component includes a rectangular base plate and a purlin-type structure perpendicular to the center of the base plate. Bolt holes are provided on the vertical center of three sides of the purlin structure. Mounting holes matching expansion bolts are provided on both sides of the rectangular base plate. Each set of brackets contains two identical bracket fixing components arranged symmetrically. The bracket fixing components are fixed to the load-bearing wall by expansion bolts and connected to the bolt holes on the back of the horizontal brackets through the purlin-type structure.

[0006] Each adjustable single-door bracket set includes two bracket connectors, one vertical bracket, a number of bolts matching the bolt holes, two horizontal brackets, two bracket fixing parts, and a number of expansion bolts matching the expansion bolt holes.

[0007] The bracket connector adopts a bottom support crossbeam type edge-wrapping structure, and its side and bottom surfaces form a 90° right-angle connection.

[0008] The vertical and horizontal supports are connected at a 90° right angle through support connectors and secured with bolts to ensure the stability of the overall structure.

[0009] The purlin-type structure of the bracket fastener can be flexibly adjusted by the mutual cooperation of the bolt holes with the horizontal array bolt holes of the horizontal bracket.

[0010] The purlins of both the vertical and horizontal supports are designed with anti-slip teeth and are equipped with elongated bolt holes for easy fine-tuning during installation.

[0011] The bracket fastener also adopts a bottom support crossbeam type edge structure, and its expansion bolt mounting holes are designed with elongated holes to provide adjustment margin during the installation process. Beneficial effects

[0012] This bracket adopts an innovative modular design. Through the optimized combination of bracket connectors, vertical brackets, horizontal brackets, and bracket fixing components, it achieves multi-dimensional adjustment functions. These design features together give the bracket excellent ease of installation, structural stability, and environmental adaptability. It effectively solves the technical defects of traditional brackets, such as limited adjustment capabilities, complex installation, and insufficient stability. It is particularly suitable for door support scenarios that require precise installation. The overall structure is simple and reliable, and the installation and adjustment are convenient, making it a promising candidate for market application. Attached Figure Description

[0019] like Figure 1 , 2 As shown in Figure 3

[0020] An adjustable single-door bracket can be easily wall-mounted on a load-bearing wall 7. The bracket consists of a bracket connector 1, a vertical bracket 2, bolts 3, horizontal brackets 4, bracket fixing parts 5, and expansion bolts 6. The bracket connector 1 adopts a purlin-type structure design, forming a 90° right-angle connection through a central bend. It includes a side and a bottom surface. The side surface has a bolt hole at its vertical center, and the bottom surface has two sides bent upwards to form a stable groove structure with bolt holes at its horizontal center. Each bracket set is equipped with two completely symmetrically arranged bracket connectors 1. The vertical bracket 2 adopts a purlin-type structure with a vertical array of bolt holes on its back, and cooperates with two horizontal brackets 4, which also adopt a purlin-type structure and have horizontal array of bolt holes. The connection is achieved by the bottom surface of the connector being concave... The groove connects to both ends of the vertical bracket 2, and the top groove connects to the front end of the horizontal bracket 4, forming a stable support frame. The bracket fixing component 5 includes a rectangular base plate and a vertically arranged purlin-type structure. Bolt holes are provided at the vertical center of three sides, and mounting holes for matching expansion bolts 6 are provided on both sides of the base plate. Each bracket set is equipped with two symmetrically arranged bracket fixing components 5, which are fixed to the wall by expansion bolts 6, achieving a reliable connection with the horizontal bracket 4. This bracket adopts a bottom support crossbeam-type edge-wrapping structure to ensure the stability of the 90° right-angle connection. The installation distance can be flexibly adjusted by the cooperation of bolt holes and array bolt holes. The anti-slip tooth structure designed on the inner edge of the purlin is combined with the elongated oval bolt holes to facilitate installation and fine adjustment. The elongated oval design of the mounting holes for expansion bolts 6 further provides adjustment margin.

[0021] During installation, first place the two bracket fixing parts 5 symmetrically on the load-bearing wall 7, and use expansion bolts 6 to initially fix them through the elongated holes on the fixing parts. Connect the two bracket connectors 1 to the two ends of the vertical bracket 2 respectively. When connecting, align the groove on the bottom of the connector with the back of the vertical bracket 2 and fix it with bolts 3. Then insert the front ends of the two horizontal brackets 4 into the grooves on the top of the two connectors respectively, and fix them with bolts 3. At this time, the vertical bracket 2 and the horizontal brackets 4 form a stable right-angle frame through the connectors. Finally, connect the assembled frame to the fixing parts on the wall, align the bolt holes on the back of the horizontal brackets 4 with the holes on the purlins of the fixing parts, and fix them with bolts 3. After installation, the brackets will be firmly supported on the wall and can be adjusted in an appropriate position according to actual use needs.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
