Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an easy-to-install energy-saving curtain wall. Background Technology

[0002] As a commonly used exterior envelope structure in modern buildings, the installation quality and sealing performance of curtain walls directly affect the building's aesthetics and energy efficiency. In current curtain wall installation processes, corner brackets and bolts are typically used to fix the curtain wall panels to the keel. However, this traditional installation method requires extremely high precision. Workers must simultaneously support and align the panels and tighten multiple bolts in a high-altitude working environment. This not only makes the installation process time-consuming, labor-intensive, and inefficient, but also makes it difficult to ensure the flatness between adjacent curtain wall panels.

[0003] Furthermore, existing curtain wall panel joints are typically sealed manually with sealant. Due to the complex construction site environment, the quality of manual sealant application is difficult to control consistently, leading to issues such as sealant breakage or aging and detachment. Once the seal fails, rainwater and hot or cold air can seep in through the gaps, causing a decrease in the overall airtightness and watertightness of the curtain wall. This severely impacts the building's thermal insulation performance, failing to meet the high standards of energy conservation and environmental protection required by modern buildings.

[0004] Therefore, this utility model proposes an easy-to-install energy-saving curtain wall to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-install energy-saving curtain wall, aiming to improve the problems in the existing technology, such as the difficulty in alignment during curtain wall installation, the cumbersome fixing operation leading to low construction efficiency, and the reliance on manual caulking at the joints resulting in poor airtightness and unsatisfactory energy-saving effects.

[0011] Preferably, the first slide groove extends along the axial direction of the fixed shell and its end is connected to a circumferential groove. The slider cooperates with the first slide groove to restrict the rotating shell from moving axially first and then rotating circumferentially.

[0012] Preferably, the limiting rod and the insert rod are perpendicularly distributed. The length of the limiting rod is less than the length of the second slide groove and greater than the width of the second slide groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 This utility model provides an easy-to-install energy-saving curtain wall, which aims to solve the structural defects of the prior art, such as difficulty in alignment during curtain wall installation, cumbersome fixing, and insufficient sealing at the splicing points leading to increased energy consumption.

[0028] The main support structure of this easy-to-install energy-saving curtain wall includes a wall 1 and a first L-shaped steel plate 2 fixedly connected to the side wall of the wall 1 by multiple sets of bolts 8. The wall 1 serves as the basic load-bearing surface of the entire building facade, and the first L-shaped steel plate 2 serves as the root support for fixing the curtain wall components. To achieve modular installation of the curtain wall units, this easy-to-install energy-saving curtain wall includes a first curtain wall 3 and a second curtain wall 6. The inner side wall of the first curtain wall 3 is fixedly connected to the second L-shaped steel plate 4 by welding, and the inner side wall of the second curtain wall 6 is also fixedly connected by welding. The second L-shaped steel plate 4 is fixedly connected in a manner that corresponds to the welding position of the second L-shaped steel plate 4 on the back of the first curtain wall 3 and the second curtain wall 6 and the spatial position of the first L-shaped steel plate 2 fixed on the wall 1. The curtain wall is installed by the cooperation of the first L-shaped steel plate 2 and the second L-shaped steel plate 4. In order to achieve a fast and stable connection, this embodiment is provided with an installation component 5 for fixing the first curtain wall 3 and the second curtain wall 6 to the wall 1, and a splicing component 7 is provided for lateral locking and sealing between the first curtain wall 3 and the second curtain wall 6.

[0029] The mounting assembly 5 includes a fixed shell 502, a rotating shell 501, an insert rod 505, and a limiting rod 506. The fixed shell 502 is fixedly connected to the outer surface of the second L-shaped steel plate 4 by welding or bolt fastening. The fixed shell 502 has a cylindrical hollow structure. The inner side wall of the fixed shell 502 has a first sliding groove 503. The rotating shell 501 is sleeved on the outside of the fixed shell 502. The rotating shell 501 and the fixed shell 502 form a sliding and rotating connection relationship. The inner wall of the rotating shell 501 is integrally formed or fixedly connected to a slider 504. The slider 504 is slidably connected inside the first sliding groove 503. The first sliding groove 503 restricts the movement trajectory of the slider 504, thereby limiting the movement mode of the rotating shell 501 relative to the fixed shell 502.

[0030] The insertion rod 505 is fixedly connected to the center of the rotating shell 501. The insertion rod 505 moves synchronously with the rotating shell 501. In order to cooperate with the insertion and locking of the insertion rod 505, the surfaces of the first L-shaped steel plate 2 and the second L-shaped steel plate 4 are provided with second grooves 508 at corresponding positions where they fit together, allowing the insertion rod 505 to pass through. The limiting rod 506 is fixedly connected to the side wall of the insertion rod 505. After the limiting rod 505 passes through the second groove 508, it is used to hook the inner side wall of the first L-shaped steel plate 2. In order to give the installation component 5 the ability to automatically reset and lock, the side wall of the insertion rod 505 is also fitted with a first spring 507. The first spring 507 is a helical compression spring. One end of the first spring 507 abuts against the side of the limiting rod 506, and the other end of the first spring 507 abuts against the outer wall of the second L-shaped steel plate 4. In the natural state, the first spring 507 is in an extended or slightly compressed state, pulling the limiting rod 506 towards the second L-shaped steel plate 4.

[0031] As a preferred embodiment, in order to achieve seamless connection and anti-detachment function between the first curtain wall 3 and the second curtain wall 6, the easy-to-install energy-saving curtain wall also includes a splicing component 7, please refer to... Figure 3 and Figure 5The splicing component 7 includes a connecting block 701 and a fixing block 702. The connecting block 701 is fixedly connected to the side wall edge of the second curtain wall 6, and the fixing block 702 is fixedly connected to the outside of the connecting block 701. The connecting block 701 is set along the height direction of the second curtain wall 6, which gives the fixing block 702 sufficient longitudinal length to ensure connection strength. The splicing end of the first curtain wall 3 is provided with a guide rail groove 703, which extends along the height direction of the first curtain wall 3. The fixing block 702 is slidably connected inside the guide rail groove 703. The outer contour of the fixing block 702 is adapted to the inner contour of the guide rail groove 703. By sliding the fixing block 702 along the longitudinal direction of the guide rail groove 703, the alignment and splicing of the first curtain wall 3 and the second curtain wall 6 in the vertical direction are realized. After the splicing is completed, the front surface of the first curtain wall 3 and the front surface of the second curtain wall 6 are on the same plane, ensuring the overall aesthetics and flatness of the curtain wall.

[0032] In another preferred embodiment, to enhance the locking force after splicing and prevent lateral separation, the splicing assembly 7 further includes a protrusion 707. A groove 704 is formed on the surface of the fixing block 702. A cavity 705 is formed inside the first curtain wall 3 corresponding to the groove 704. The cavity 705 is located deep within or on the side wall of the guide rail groove 703. A second spring 706 is fixedly connected to the inner wall of the cavity 705. The protrusion 707 is fixedly connected to the free end of the second spring 706. The protrusion 707 is slidably connected within the cavity 705. Under the elastic force of the second spring 706, the protrusion 707 extends out of the cavity 705 and enters the guide rail groove 705. In the trend of the 3-region, when the fixing block 702 slides into the correct position, the protrusion 707 engages inside the groove 704. The top of the protrusion 707 is provided with a guide slope. The inclination direction of the guide slope is adapted to the direction in which the fixing block 702 is pushed into the guide rail groove 703, that is, a gradually rising slope is formed in the pushing direction, so that the fixing block 702 can squeeze the guide slope to force the protrusion 707 to retract into the cavity 705. In addition, the end of the protrusion 707 away from the second spring 706 is flat, and the inner wall shape of the groove 704 is adapted to the shape of the protrusion 707. The two cooperate to form a one-way locking structure to prevent the fixing block 702 from retracting in the opposite direction.

[0033] As a further preferred embodiment, in order to standardize the operating feel of the rotating shell 501 and prevent misoperation, the first slide groove 503 extends along the axial direction of the fixed shell 502 and has a circumferential groove at its end, forming an "L" shaped path. The slider 504 cooperates with the first slide groove 503 to restrict the rotating shell 501 from moving forward a certain distance along the axial direction first, so that the insertion rod 505 is fully inserted into the second slide groove 508 before it can rotate circumferentially, thereby driving the limiting rod 506 to rotate to the locked position. The limiting rod 506 and the insertion rod 505... The 5 are vertically distributed. The length of the limiting rod 506 is less than the length of the second slide groove 508 but greater than the width of the second slide groove 508. This size design ensures that the limiting rod 506 can pass smoothly through the second slide groove 508 at a specific angle. After rotating 90 degrees or other preset angles, the two ends of the limiting rod 506 will be blocked by the plates on both sides of the second slide groove 508, so that it cannot be pulled out. With the pull of the first spring 507, the limiting rod 506 is tightly pressed against the inner wall of the first L-shaped steel plate 2 to complete the stable locking.

[0034] Working principle: Before installation, the first L-shaped steel plate 2 is fixed to the side wall of the wall 1 by multiple sets of bolts 8. At the same time, the second L-shaped steel plate 4 is fixed by welding to the inner side wall of the first curtain wall 3 and the second curtain wall 6 at the position corresponding to the first L-shaped steel plate 2. Then, the first curtain wall 3 is installed on the side wall of the wall 1 by the installation component 5. Subsequently, the first curtain wall 3 and the second curtain wall 6 are connected by the splicing component 7.

[0035] When the first curtain wall 3 is installed, the construction personnel press the rotating shell 501 fixed on the fixed shell 502 on the outside of the second L-shaped steel plate 4 in the installation component 5, so that it slides along the axial direction, and drives the slider 504 on the inner wall of the rotating shell 501 to slide precisely along the first sliding groove 503 on the inner side of the fixed shell 502. At the same time, the insertion rod 505 fixedly connected inside the rotating shell 501 is inserted into the second sliding groove 508 corresponding to the first L-shaped steel plate 2 and the second L-shaped steel plate 4 to form a preliminary connection. The first spring 507 on the side wall of the insertion rod 505 is compressed elastically. After the insertion rod 505 is fully inserted, the rotating shell 501 is rotated, which drives the limiting rod 506 on the side wall of the insertion rod 505 to deflect around the axis to fit the outer wall of the first L-shaped steel plate 2. After the rotating shell 501 is released, the first spring 507 releases elastic potential energy to push it to reset, so that the limiting rod 506 firmly abuts against the steel plate to complete the locking and fixing.

[0036] When splicing the first curtain wall 3 and the second curtain wall 6, align the fixing block 702 on the outer side of the connecting block 701 fixed to the side wall of the second curtain wall 6 with the guide rail groove 703 at the splicing end of the first curtain wall 3, and slowly push it in along the axial direction of the guide rail groove 703. The guide rail groove 703 guides the splicing to ensure accuracy and no misalignment. When the fixing block 702 slides to the bottom preset position, the protrusion 707 in the internal cavity 705 of the first curtain wall 3, pulled by the second spring 706, automatically slides into the fixing block 702 under the pulling force of the second spring 706. Within the recessed groove 704, the second spring 706, with one end fixed to the inner wall of the cavity 705 and the other end connected to the bottom of the protrusion 707, is stretched to enhance the locking force. Because the top of the protrusion 707 has a sloping structure, it can be smoothly squeezed into the cavity 705 during splicing. After splicing, the flat end of the protrusion 707 fits tightly with the inner wall of the recessed groove 704 to form a one-way locking structure, which cannot be disassembled in reverse. This ensures the overall stability of the curtain wall, improves the sealing performance, prevents rainwater and dust from seeping in, and enhances the energy-saving and heat-insulating effect.
