Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a curtain wall installation and layout device for buildings. Background Technology

[0002] Traditional curtain wall layout work often uses temporary welded steel brackets to fix the baseline, which has problems such as low positioning accuracy and time-consuming repeated adjustments. At the same time, the high temperature of welding can easily damage the building surface and cannot meet the micro-displacement requirements of the curved surface installation of the curtain wall. When positioning the steel wire, the steel wire is fixed by binding with iron wire or pressing vertically with bolts, which is prone to slippage and causing the baseline to shift. The device needs to be cut and destroyed to disassemble, resulting in insufficient reuse rate, which increases construction costs and generates a lot of waste.

[0003] Therefore, in order to address the above problems, a curtain wall installation and layout device for buildings is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that rely on wire binding or bolt vertical clamping to fix the steel wire during positioning, which are prone to slippage and cause reference deviation, require cutting and destruction for disassembly, have insufficient reuse rate, increase construction costs and generate a lot of waste, this utility model provides a curtain wall installation and layout device for buildings.

[0005] The technical solution of this utility model is as follows: A curtain wall installation and layout device for buildings includes an angle steel, the rear half of which is placed inside the building, and the front half of which extends out of the building and is located outside. A long strip-shaped reserved groove is opened at the front of the angle steel. A clamping plate is slidably connected to the right side of the angle steel. A first connecting piece is threadedly connected to the clamping plate. Rotating the first connecting piece can fix the position of the clamping plate. The clamping plate is used to fit against the exterior wall of the building to maintain the overall stability of the angle steel.

[0006] Preferably, the angle steel has a Z-shaped structure.

[0007] Preferably, the angle steel has two elongated pre-drilled holes at the rear, which are used for quick installation with the building surface.

[0008] Preferably, a nylon pad is slidably connected to the reserved groove, and a fastener is threadedly connected to the nylon pad. The fastener is slidably connected to the reserved groove, and a second connector is threadedly connected to the fastener. The bottom of the second connector contacts the angle steel.

[0009] Preferably, both the second connector and the fastener have a hollow structure in the middle to facilitate the installation of steel wires.

[0010] Preferably, the upper part of the second connector is threaded with a bolt, which is perpendicular to the second connector and is used to tighten and fix the installation steel wire.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are: This utility model uses a horn bolt to drive and lock the steel wire laterally, achieving automatic and balanced transmission of tension force, eliminating local stress concentration in traditional vertical pressing, and the modular, purely mechanical design supports quick assembly and disassembly by a single person, avoiding welding pollution and improving equipment turnover rate. At the same time, the lightweight structure reduces the risk of high-altitude operations, making it particularly suitable for the construction of ultra-high-rise irregular curtain walls.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] A type of installation and wiring device for building curtain walls, such as Figures 1-4As shown, the structure includes an angle steel 1 with a Z-shaped structure. The rear half of the angle steel 1 is placed inside the building, while the front half extends outwards. Two elongated pre-drilled holes 2 are located at the rear of the angle steel 1 for quick installation onto the building surface. An elongated pre-drilled groove 3 is located at the front of the angle steel 1. A clamping plate 4 is slidably connected to the right side of the angle steel 1, and a first connecting piece 6 is threaded onto the clamping plate 4. Rotating the first connecting piece 6 fixes the clamping plate 4 in place. The clamping plate 4 is used to fit snugly against the building's exterior wall, maintaining... To ensure the overall stability of angle steel 1, a nylon pad 7 is slidably connected to the reserved groove 3, and a fastener 8 is threadedly connected to the nylon pad 7. The fastener 8 is slidably connected to the reserved groove 3, and a second connector 9 is threadedly connected to the fastener 8. The bottom of the second connector 9 contacts the angle steel 1. Both the second connector 9 and the fastener 8 have hollow structures in the middle to facilitate the passage of the steel wire. A horn bolt 10 is threadedly connected to the upper part of the second connector 9. The horn bolt 10 is perpendicular to the second connector 9 and is used to press and fix the steel wire.

[0019] It should be noted that this device achieves the positioning of the curtain wall steel wire through multi-stage mechanical adjustment. The horizontal part of the rear half of the Z-shaped angle steel 1 is anchored to the building structure through two 120mm long reserved holes 2. The M12 expansion bolts can be adjusted laterally within a range of ±60mm. After tightening, they form a rigid support with a pull-out force ≥20kN. The cantilevered front half extends to the outside of the building. The 200mm long reserved groove 3 has an embedded track that forms a sliding pair with the slider of the fastener 8. The second connecting piece 9 has a 20mm through hole in the middle for the steel wire to pass through. The inside of the connecting piece is machined with a threaded hole in the horizontal direction. The laterally screwed-in horn bolt 10 constitutes a radial clamping mechanism. After the steel wire is inserted into the through hole, the operator rotates the horn bolt horizontally. The angle bolt 10 rotates 90°, and the cone head advances and presses forward until it makes contact with the surface of the steel wire. The specific process is as follows: the horizontal section of the angle steel 1 is attached to the building structure surface, the expansion bolt is temporarily fixed through the reserved hole 2, the angle steel 1 is roughly positioned through the bolt in the reserved hole 2 to complete the specific installation, then the clamp 4 is pushed to fit tightly against the outer wall surface, and then the first connecting piece 6 is tightened to generate lateral pressure, eliminate cantilever vibration, and improve installation stability. Then, the fastener 8 is slid along the reserved groove 3 to the design position, and the second connecting piece 9 is rotated to press the top position against the lower surface of the angle steel 1 to form anti-slip friction. After that, the steel wire is passed through the through hole of the second connecting piece 9, and the angle bolt 10 is screwed in horizontally until it contacts the steel wire.

[0020] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
