Description

Technical Field

[0001] This application relates to the field of passive house building technology, specifically to an integrated embedded part for ultra-low energy consumption energy-saving slab channel anchor bars in buildings. Background Technology

[0002] Passive houses are gaining attention for their superior energy efficiency and comfort. In passive house design, the curtain wall, as a crucial component of the building envelope, needs to be tightly connected to the main concrete structure and its thick external insulation layer to ensure the building's airtightness and thermal performance. Traditional methods for installing connecting components often involve on-site high-altitude welding, which is prevalent in the connection between passive house curtain walls and the concrete structure. However, this method faces several challenges.

[0003] First, due to the difficulty of quality control, the inconvenience of operating in a circular manner during high-altitude welding can lead to inconsistent connection quality, which directly affects the safety and durability of the building. Even subtle differences in welding techniques can cause significant variations in joint strength, thus impacting the overall structural stability.

[0004] Furthermore, on-site high-altitude welding is economically costly, requiring not only skilled welders to perform complex high-altitude operations but also additional protective measures and equipment, all of which increase the overall project cost. At the same time, this method of operation demands high levels of worker skill and involves a hazardous working environment, potentially leading to inefficiency.

[0005] Finally, the falling welding slag from high-altitude welding poses a significant safety hazard. The slag could injure ground workers during its descent, or even cause a fire, seriously threatening the safety of the construction site. Utility Model Content

[0006] Therefore, this application provides an integrated embedded part for ultra-low energy consumption energy-saving slab channel anchor bars in buildings, to solve the problems of inconsistent installation quality, increased costs, and potential safety hazards caused by high-altitude welding on construction sites in the existing technology.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] An integrated embedded component for ultra-low energy consumption slab channel anchor bars in buildings, comprising, from back to front, the following components:

[0009] Threaded steel bars are embedded in the concrete layer;

[0010] The corbel connector is located inside the insulation layer outside the concrete layer and is fixed to the front end of the threaded steel bar.

[0011] The mounting plate is located outside the insulation layer and is attached to the outer surface of the insulation layer, and is fixed to the front end of the bracket connector;

[0012] Connecting bolts are installed vertically on the front end face of the mounting plate to fix the curtain wall.

[0013] Optionally, the corbel connector is placed vertically and has a dovetail shape that is narrower at the front and wider at the back.

[0014] Optionally, the front end of the mounting plate has a horizontal groove facing rearward; a slider slides in the groove, and the connecting bolt is installed on the slider and moves left and right in the groove with the slider.

[0015] Optionally, the slider has a through hole for the connecting bolt to pass through, and the connecting bolt is threaded into the through hole; and the connecting bolt has an internal hexagonal hole along its own axial direction.

[0016] Optionally, the front end face of the slider and the corresponding end face of the groove are mutually cooperating inclined surfaces.

[0017] Optionally, the bracket connector includes two L-shaped plates and a composite L-shaped plate, with the two L-shaped plates arranged back to back and the composite L-shaped plate positioned between the two L-shaped plates; the rear end of the composite L-shaped plate is divided into two independent bent portions, with the two bent portions facing the two L-shaped plates respectively.

[0018] Optionally, the rear end of the threaded steel bar is fixed with a binding bar by welding, and the binding bar is arranged side by side with the threaded steel bar.

[0019] Optionally, the surface of the bracket connector is provided with multiple heat-insulating holes.

[0020] Optionally, the mounting plate is a hot-dip galvanized steel plate.

[0021] Optionally, the threaded steel bars, the corbel connectors, and the mounting plates are all fixedly connected by welding.

[0022] Compared with the prior art, this application has at least the following beneficial effects:

[0023] 1. The components of this application can be directly welded in the factory, including threaded steel bars, bracket connectors, mounting plates, and connecting bolts, without the need for high-altitude welding on the construction site. This method not only ensures high standards and high quality of installation, but also reduces the requirements for high-altitude operations on site, effectively reducing costs and avoiding safety hazards caused by falling welding slag during on-site operations.

[0024] 2. The dovetail design of the corbel connector, which is narrow at the front and wide at the back, increases the contact area with the main building structure, resulting in better load-bearing capacity, more robust installation, earthquake resistance and shock absorption, improved stability, and greater safety when swaying left and right.

[0025] 3. Since passive house design requires a thick insulation layer, setting up multiple bracket connectors provides ample space and distance for placing the insulation layer, allowing the insulation layer to be better fixed to the building's main surface and providing a more stable installation foundation for the curtain wall.

[0026] 4. The cooperation between the slide and the slider allows the position of the connecting bolts to be adjusted, making it easy to adapt to various installation situations. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0038] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0039] An integrated embedded part for ultra-low energy consumption and energy-saving slab channel anchor bars in buildings, referring to Figures 1-4 From back to front, the structure includes threaded steel bar 1, bracket connector 2, and mounting plate 3. Specifically, threaded steel bar 1 is embedded in the concrete layer, which reduces thermal conductivity and meets energy-saving and environmental protection requirements. Since passive houses are designed for insulation, the insulation layer is relatively thick and heavy. Sufficient space is needed between the main building and the curtain wall to install and fix the insulation material. Bracket connector 2 is located inside the insulation layer outside the concrete layer, fixed to the front end of threaded steel bar 1. It is suitable for insulation layers of different lengths, spaces, thicknesses, and directions, reserving installation space for the curtain wall. Mounting plate 3 is a hot-dip galvanized steel plate, fixed to the front end of bracket connector 2. Supported by bracket connector 2, it is located outside the insulation layer and adheres to the outer surface of the insulation layer. On the one hand, it provides an installation position for the curtain wall; on the other hand, it further improves the stability of the component installation with the help of the insulation layer.

[0040] Among them, the threaded steel bar 1 and the corbel connector 2, and the corbel connector 2 and the mounting plate 3 are all connected by welding to enhance their connection strength.

[0041] Furthermore, the rear end of the threaded steel bar 1 is also fixedly connected to a binding bar 4 by welding. The binding bar 4 is arranged side by side with the threaded steel bar 1, which makes the connection structure between the threaded steel bar 1 and the concrete layer more secure in tensile strength and has a significant effect on reducing heat conduction in the curtain wall of high-rise buildings.

[0042] To improve structural strength, the corbel connector 2 is placed vertically and has a dovetail shape that is narrower at the front and wider at the back, which can meet the needs of different working conditions. It also has functions such as seismic resistance, shear resistance, and vibration damping, making the curtain wall of high-rise buildings safer under strong winds, while also being energy-efficient and environmentally friendly. It consists of multiple independent plate-like structures. In this embodiment, the corbel connector 2 includes two L-shaped plates 5 and a composite L-shaped plate 6. The two L-shaped plates 5 are parallel and back-to-back, and the composite L-shaped plate 6 is located between the two L-shaped plates 5. The rear end of the L-shaped steel member is bent, serving to support and connect the main building structure. To improve overall balance, the rear end of the composite L-shaped plate 6 is divided into two independent bent sections. These two bent sections separate from the middle of the composite L-shaped plate 6 and face towards the two L-shaped plates 5 respectively, jointly strengthening the structural strength.

[0043] Multiple heat-insulating holes 7 are opened on the surface of L-shaped plate 5 and composite L-shaped plate 6. The heat-insulating holes 7 are round holes, which can reduce heat conduction and make the building structure more environmentally friendly and energy-saving.

[0044] When installing the threaded steel bar 1, holes can be drilled on the bent surfaces at the rear ends of the corresponding L-shaped plate 5 and composite L-plate 6. The threaded steel bar 1 can be inserted into the holes and then welded on both sides to improve the connection strength between the two.

[0045] To provide an installation location for the curtain wall, connecting bolts 8 are installed on the front end face of the mounting plate 3.

[0046] Specifically, the front end of the mounting plate 3 has a transverse groove 9 facing rearward. The groove 9 does not penetrate the left and right sides of the mounting plate 3 to prevent the connecting bolt 8 from slipping out. A slider 10 slides within the groove 9. The slider 10 has a through hole for the connecting bolt 8 to pass through, and the connecting bolt 8 is threaded into the through hole. In the design, a certain amount of clearance is left between the front and rear end faces of the slider 10 and the corresponding faces of the groove 9 to ensure that the slider 10 can slide smoothly. Since the connecting bolt 8 and the slider 10 are threadedly engaged, rotating the connecting bolt 8 can drive the connecting bolt 8 to move back and forth within the through hole, moving away from or closer to the rear end face of the groove 9. The rear end of the connecting bolt 8 and the front end face of the slider 10 respectively abut against the front and rear end faces of the groove 9, thereby fixing the slider 10 within the groove 9 by friction.

[0047] To facilitate the rotation of the connecting bolt 8, an internal hexagonal hole 11 is provided inside the connecting bolt 8 along its own axial direction, and the connecting bolt 8 can be rotated by using a hexagonal wrench.

[0048] Furthermore, the front end face of the slider 10 and the corresponding end face of the groove 9 are set as mutually cooperating inclined surfaces, so that the two are hooked together, resulting in better force-bearing performance.

[0049] Reference Figure 5 and Figure 6In some embodiments, corresponding meshing toothed grooves can be provided on the inclined surfaces of the slider 10 and the slide groove 9, with the toothed grooves arranged sequentially along the length of the slide groove 9. When the position of the slider 10 needs to be adjusted, the connecting bolt 8 is rotated away from the rear wall of the slide groove 9, thereby distancing the toothed grooves on the slider 10 and the slide groove 9 from each other, so that the slider 10 can slide smoothly. After the slider 10 slides to the designated position, the connecting bolt 8 is rotated to press against the slide groove 9, and the slider 10 is moved forward until the teeth on the front end face of the slider 10 mesh with the teeth on the slide groove 9, completing the locking and preventing displacement.

[0050] In practice, depending on the material of the curtain wall, the installation location, or other working conditions, different numbers of sliders 10 and connecting bolts 8 are installed in the sliding groove 9 to increase the load-bearing capacity.

[0051] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
