Description

Technical Field

[0001] This utility model relates to the field of construction technology for building curtain wall engineering, and specifically to a quick-disassembly curtain wall railing. Background Technology

[0002] In the field of building curtain wall construction, guardrails, as a key component ensuring construction safety and subsequent protection, have long faced numerous unresolved issues regarding their installation and fixing methods. Traditional guardrail fixing often employs pre-embedded methods, where connectors are embedded in the building structure beforehand, and the guardrails are then welded or bolted to these pre-embedded components. The biggest limitation of this method is its highly variability in fixing position. If the pre-embedded position deviates, whether due to errors in the measurement and layout stage or displacement during concrete pouring, it cannot be effectively adjusted in subsequent installation stages. This often leads to insufficient installation accuracy and may even require destructive modifications to the completed structure, affecting not only construction progress but also potentially damaging the overall integrity of the building structure.

[0003] Meanwhile, the construction process for pre-embedded fixing is extremely complicated. From the precise positioning and binding of pre-embedded components to the protection of finished products during concrete pouring, every step requires strict control, demanding a high level of technical skill from construction workers and being easily affected by on-site environmental factors. In large-scale construction scenarios, this method, which relies on meticulous manual operation, is difficult to standardize. Differences in the skill levels of different construction teams can easily lead to inconsistent quality in guardrail installation, increasing later maintenance costs and potentially creating safety hazards due to improper installation.

[0004] Furthermore, as the construction industry's requirements for construction efficiency, environmental friendliness, and recyclability continue to rise, the drawbacks of traditional pre-embedded methods are becoming increasingly apparent. Once installed, pre-embedded components form a permanent connection with the building structure. When the railings need to be replaced, repaired, or the building is renovated, the dismantling process often requires cutting, breaking, and other destructive operations, generating a large amount of construction waste, which is inconsistent with the development trend of the modern construction industry. Moreover, for highly modular building components such as curtain wall units, pre-embedded railings lack flexible adaptability to the units, making it difficult to meet the construction needs of rapid assembly and precise connection of the units, severely restricting the improvement of the industrialized construction level of curtain wall projects. Therefore, developing a quick-disassembly curtain wall railing fixing method that can overcome the above-mentioned defects has become an urgent need for the industry's development. Utility Model Content

[0005] The purpose of this invention is to provide a quick-detachable curtain wall railing, which solves the problem of cumbersome installation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-detachable curtain wall railing includes multiple connecting horizontal bars, multiple central vertical mounting slots, and two end vertical mounting slots. The central and end vertical mounting slots are detachably installed on the curtain wall columns. One end of each connecting horizontal bar is threaded to the right side of the central vertical mounting slot or the side of the end vertical mounting slot, and the other end is inserted into the left side of the central vertical mounting slot or the side of the end vertical mounting slot.

[0008] Preferably, the central vertical mounting groove is a U-shaped groove, with multiple screws horizontally mounted on the right side of the U-shaped groove and multiple insert rods horizontally mounted on the left side of the U-shaped groove.

[0009] Preferably, the end vertical mounting groove is an L-shaped groove, and multiple inserts or multiple screws are horizontally mounted on the side of the L-shaped groove.

[0010] Preferably, the connecting crossbar is a straight bar, and the length of the bar differs from the straight-line distance between two adjacent columns by the length of one insertion rod.

[0011] Preferably, a connecting nut or end cap is coaxially provided at one end of the connecting crossbar, and the screw is threadedly connected to the connecting nut or the end cap.

[0012] Preferably, a threaded hole is provided at the center of the end cap, and a plurality of weight-reducing holes are evenly spaced around the threaded hole.

[0013] Preferably, the connecting crossbar is an arc-shaped bar, and the length of the bar differs from the arc spacing between two adjacent columns by the length of one insert rod.

[0014] Preferably, the connecting crossbar includes a rod body and a connector, wherein the connector is a T-shaped bushing with a threaded hole and threadedly connected to the screw; one end of the rod body is inserted into the connector and the other end is inserted into the insert rod.

[0015] Preferably, the other end of the connecting crossbar is provided with a socket, the plug is inserted into the socket, one end of the connecting crossbar connected to the screw is unscrewed, and the other end of the connecting crossbar is inserted into the plug.

[0016] Preferably, a reinforcing nut is provided on the screw, close to the right side of the central vertical mounting groove.

[0017] In this utility model, the railing is suitable for room or corridor railing design. The integrated structure achieves standardized installation, is easy to install, has a simple fixing method, saves manpower and pre-embedding, is easy to disassemble, and the installation height is adjustable.

[0018] The guardrails achieve standardized and rapid installation. After production, they can be directly assembled on-site, and can be replaced or adjusted in height later, thus achieving both functional use and aesthetic appeal.

[0019] The rubber strip increases the friction between the central vertical mounting groove and the curtain wall column, and also provides insulation to prevent damage to the finished curtain wall surface after the bolts are tightened.

[0020] One end of the connecting crossbar is connected to the screw rod via a thread, and the other end is connected to the plug rod via a plug. The installation of a single connecting crossbar can be completed simply by unscrewing the threaded connection end. The operation is convenient and efficient, greatly reducing the time required for installation and disassembly, and is especially convenient for later maintenance, replacement or modification.

[0021] The connecting crossbars can be straight or curved, matching the straight or curved spacing between adjacent columns.

[0022] The central vertical mounting groove is a U-shaped groove, and the end vertical mounting grooves are L-shaped grooves, which are suitable for columns with no obstruction in the middle of the curtain wall and columns with obstruction on both sides, respectively. The installation method of the plug or screw is flexible, and welding or threaded connection can be selected according to the actual scene to meet the installation needs of different curtain wall structures.

[0023] The connecting nut at the end of the crossbar is suitable for scenarios with a lower budget, while the end cap is suitable for scenarios with a higher budget and high precision requirements. The weight-reducing hole on the end cap can also reduce weight while ensuring precision, providing users with a variety of options.

[0024] The reinforcing nut on the screw improves the stability of the connection between the screw and the central vertical mounting groove.

[0025] The length design of the connecting crossbar matches the length of the insertion rod, ensuring the accuracy of the connection; the connection method between the central vertical mounting groove and the column, as well as the matching structure of each component, are all based on the actual installation and use perspective. While ensuring structural strength, they simplify the operation process and have high promotional value. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-5 The illustrated quick-detachable curtain wall railing includes multiple connecting horizontal bars 1, multiple central vertical mounting slots 2, and two end vertical mounting slots 3. The central and end vertical mounting slots 2 and 3 are detachably mounted on the curtain wall columns 12. The connecting horizontal bars 1 are made of galvanized steel pipe or stainless steel pipe. Galvanized steel pipe railings have a lighter load-bearing capacity, are easier to manufacture in bending shapes, and are inexpensive; stainless steel railings do not require surface treatment, are easy to maintain, and have a long service life. Rubber strips are provided on the inner surfaces of the central and end vertical mounting slots 2 and 3 to protect the columns.

[0034] To minimize damage to the curtain wall columns during the installation of the guardrail, after adjusting the installation position of the central vertical mounting groove 2 or the end vertical mounting groove 3, the central vertical mounting groove 2 or the end vertical mounting groove 3 is fixedly installed on the column by tightening screws.

[0035] One end of the connecting crossbar 1 is threaded to the right side of the middle vertical mounting groove 2 or the side of the end vertical mounting groove 3, and the other end is inserted into the left side of the middle vertical mounting groove 2 or the side of the end vertical mounting groove 3.

[0036] The central vertical mounting groove 2 is a U-shaped groove. Multiple screws 5 are horizontally installed on the right side of the U-shaped groove, and multiple insert rods 4 are horizontally installed on the left side of the U-shaped groove. The insert rods 4 or screws 5 are connected to the side of the U-shaped groove by welding or threading.

[0037] The end vertical mounting groove 3 is an L-shaped groove, and multiple insert rods 4 or multiple screw rods 5 are horizontally installed on the side of the L-shaped groove. The insert rods 4 or screw rods 5 are connected to the side of the L-shaped groove by welding or threading.

[0038] The connecting crossbar 1 is a straight bar, and its length differs from the straight-line distance between two adjacent uprights 12 by the length of one insert rod 4. A connecting nut 7 or end cap 8 is coaxially mounted at one end of the connecting crossbar 1, and a screw 5 is threaded onto the connecting nut 7 or end cap 8. Specifically, the end cap 8 has a threaded hole 80 at its center, and multiple weight-reducing holes 81 are evenly spaced around the threaded hole 80. The connecting nut 7 is suitable for budget-constrained applications, and is connected to the end of the connecting crossbar 1 using two steel or iron plates. The end cap 8 is suitable for budget-constrained applications with high precision requirements, and is installed on the end of the connecting crossbar 1 by welding.

[0039] The connecting crossbar 1 is an arc-shaped bar, and its length differs from the arc spacing between two adjacent columns 12 by the length of one insert rod 4. To facilitate the installation of the arc-shaped bar, the connecting crossbar 1 includes a bar body 10 and a connector 11. The connector 11 is a T-shaped bushing with a threaded hole, threadedly connected to the screw rod 5. One end of the bar body 10 is inserted into the connector 11, and the other end is inserted into the insert rod 4.

[0040] The other end of the connecting crossbar 1 is provided with a socket. The plug rod 4 is inserted into the socket. One end of the connecting crossbar 1, which is connected to the screw rod 5 by unscrewing, is inserted into the plug rod 4.

[0041] A reinforcing nut 9 is provided on the screw 5, close to the right side of the central vertical mounting groove 2. The reinforcing nut 9 is used to improve the connection stability of the screw 5 on the central vertical mounting groove 2.

[0042] Working principle of guardrail installation:

[0043] When the connecting crossbar 1 is a straight bar, install an end vertical mounting groove 3, install a screw 5 on the side of the end vertical mounting groove 3, and then thread one end of the connecting crossbar 1 onto the screw 5 and screw it to the bottom; then install a middle vertical mounting groove 2, align the other end of the connecting crossbar 1 with the insertion rod 4 on the left side of the middle vertical mounting groove 2, and then unscrew the threaded connection until the insertion rod 4 is inserted into the insertion hole to complete the installation of the connecting crossbar 1. Repeat the above steps until multiple connecting crossbars 1 are installed; then continue to thread the subsequent connecting crossbar 1 onto the left side of the middle vertical mounting groove 2 and screw it to the bottom, and then install another middle vertical mounting groove 2. Repeat the above steps until the turning point is reached.

[0044] When using an arc-shaped rod for connecting crossbar 1, first thread the connector 11 onto the screw 5 and tighten it to the bottom. Then, insert one end of the rod body 10 onto the connector 11. Next, install a central vertical mounting groove 2, align the rod body 10 with the insertion rod 4 on the left side of the central vertical mounting groove 2, and then untighten the threaded connection between the connector 11 and the screw 5 until the insertion rod 4 is inserted into the insertion hole, thus completing the installation of the arc-shaped rod.

[0045] Repeat the above steps until the guardrail installation is complete.

[0046] Working principle of guardrail dismantling:

[0047] When disassembling the guardrail, first screw the straight rod or connector 11 to the bottom to disengage the insert 4 from the insertion hole, then remove the vertical mounting groove 2 in the middle of the right side, then unscrew the straight rod or connector 11 to disengage from the screw 5, and finally remove the vertical mounting groove 2 in the middle of the left side or the vertical mounting groove 3 at the end. Repeat the above steps until the disassembly of the guardrail is completed.

[0048] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
