Description

Technical Field

[0001] This utility model relates to the field of curtain wall keel installation technology, and more specifically, to a curtain wall steel keel support structure that is easy to adjust. Background Technology

[0002] The steel keel of a curtain wall is the core load-bearing structure of a building curtain wall system. It is primarily made of carbon structural steel or low-alloy high-strength steel, and undergoes anti-corrosion treatments (galvanizing, spraying, etc.) to enhance durability and adapt to complex external environments. Characterized by high strength, good rigidity, and large span, it can meet the needs of various architectural styles and is widely used in curtain wall projects for high-rise buildings and large public buildings. It is a key component ensuring the safety and stability of the curtain wall system.

[0003] Currently, most curtain wall steel keel support structures use traditional bolt-fixed connections, achieving positioning through pre-drilled holes and rigid connection with the steel components. Adjusting the curtain wall steel keel requires removing multiple bolts to reposition the support structure, making the adjustment time-consuming, labor-intensive, and limiting the adjustment range. Therefore, we propose an easily adjustable curtain wall steel keel support structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an easily adjustable curtain wall steel keel support structure to solve the technical problems of time-consuming and laborious adjustment operations and small adjustment range.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easily adjustable curtain wall steel keel support structure, including an embedded part, a support mechanism provided on the embedded part, and an installation mechanism provided on the support mechanism. The support mechanism includes a fixing plate provided at the front end of the embedded part, and a frame plate provided at the front end of the fixing plate. The frame plate and the fixing plate form an insertion groove. The installation mechanism includes a U-shaped plate inserted into the insertion groove. The U-shaped plate is inverted U-shaped. The front end of the U-shaped plate is symmetrically provided with installation plates. The front end of the U-shaped plate is provided with a fixing screw between the installation plates. The curtain wall keel is provided between the installation plates. Positioning plates are rotatably installed at the upper and lower ends of the U-shaped plate.

[0006] Preferably, the curtain wall keel has a mounting hole at its rear end and an opening corresponding to the mounting hole at its front end, and the fixing screw is located in the mounting hole.

[0007] Preferably, the mounting plate has symmetrically formed waist-shaped holes, and the side end of the curtain wall keel has a support hole, with a support screw inserted into the waist-shaped hole and the support hole.

[0008] Preferably, the positioning plate includes a positioning part and a supporting part, with a rotation axis between the positioning part and the supporting part. The front part of the positioning part is curved toward the curtain wall keel, and the rear part of the positioning part is bent in the opposite direction toward the curtain wall keel.

[0009] Preferably, positioning posts are provided at equal intervals at the end of the positioning part, and positioning holes are symmetrically provided at equal intervals on the fixing plate. The size of the positioning posts is adapted to the size of the positioning holes, and the positioning posts are inserted into the positioning holes.

[0010] Preferably, the support portion is bent into an arc shape toward the curtain wall keel, the length of the support portion is greater than the bending point of the positioning portion, the rear end of the curtain wall keel has a support opening, and the end of the support portion is inserted into the support opening.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a fixed screw and a supporting screw structure, allows for adjustment by simply loosening the nut on the fixed screw, moving the curtain wall keel forward a certain distance, and allowing the positioning plate to disengage from the positioning hole and the support opening. The insertion groove formed by the frame plate and the fixed plate in the supporting mechanism provides a large left-right movement space for the installation mechanism. The installation mechanism can flexibly adjust its left and right positions within the insertion groove according to actual needs. For front-back position adjustment, the curtain wall keel can be moved back and forth along the length of the waist-shaped hole by loosening the supporting screw using the oblong hole on the installation plate. After adjustment, the relevant nuts can be tightened to fix it. This greatly simplifies the adjustment process, saves a lot of manpower and time costs, and solves the problems of time-consuming and labor-intensive adjustment operations and limited adjustment range in current methods.

[0013] 2. This utility model also features a positioning plate structure. Through the coordinated action of the positioning part and the support part, the front of the positioning part bends in an arc shape towards the curtain wall keel, while the rear part bends in the opposite direction. During installation and fixing of the curtain wall keel, the positioning plate can rotate using the pressure of the curtain wall keel moving backward, allowing the positioning post at the end of the positioning part to accurately insert into the positioning hole of the fixing plate. This securely fixes the installation mechanism to the support mechanism, preventing lateral swaying. Simultaneously, the end of the support part is inserted into the support port of the curtain wall keel, providing effective auxiliary support and significantly improving the overall structural stability. During adjustment, simply loosening the nut on the fixing screw allows the curtain wall keel to move forward, causing the positioning plate to disengage from the positioning hole and support port without affecting the flexible movement of the installation mechanism. This design balances the reliability of fixing with the convenience of adjustment. Furthermore, its unique arc-shaped bending structure perfectly adapts to the curtain wall keel and the fixing plate, ensuring smooth movement during fixing and adjustment, further enhancing the practicality of the structure.

Detailed Implementation

[0020] like Figures 1 to 5 As shown, this utility model relates to an easily adjustable curtain wall steel keel support structure, including an embedded part 101, a support mechanism 200 provided on the embedded part 101, and an installation mechanism 300 provided on the support mechanism 200. The support mechanism 200 includes a fixing plate 201 provided at the front end of the embedded part 101, a frame plate 202 provided at the front end of the fixing plate 201, and an insertion groove 203 formed between the frame plate 202 and the fixing plate 201. The installation mechanism 300 includes a U-shaped plate 301 inserted into the insertion groove 203. The U-shaped plate 301 is inverted U-shaped, and installation plates 302 are symmetrically provided at the front end of the U-shaped plate 301. Fixing screws 303 are provided between the front end of the U-shaped plate 301 and the installation plates 302. Curtain wall keel 401 is provided between the installation plates 302. Positioning plates 305 are rotatably installed at both the upper and lower ends of the U-shaped plate 301. When adjusting, the positioning plate 305 can be disengaged by loosening the nut on the fixing screw. The installation mechanism 300 can be flexibly adjusted left and right in the insertion slot 203 and front and back by means of the oblong hole 3021. The operation is simple and cost-effective. The structure of the positioning plate 305 enhances stability and takes into account both reliable fixation and convenient adjustment.

[0021] Specifically, the curtain wall keel 401 has a mounting hole 4012 at its rear end and an opening at its front end corresponding to the mounting hole 4012. The fixing screw 303 is located in the mounting hole 4012. The fixing screw 303, in conjunction with the nut, can be used to install and fix the curtain wall keel 401.

[0022] Furthermore, the mounting plate 302 has symmetrically arranged oblong holes 3021, and the side end of the curtain wall keel 401 has a support hole 4011. Support screws 304 are inserted into the oblong holes 3021 and the support holes 4011. The support screws 304 can support and fix the curtain wall keel 401, and the oblong holes 3021 can be used to adjust the front and rear position of the curtain wall keel 401.

[0023] It is worth noting that the positioning plate 305 includes a positioning part 3051 and a supporting part 3052. The positioning part 3051 and the supporting part 3052 are connected by a rotation axis. The front part of the positioning part 3051 is curved towards the curtain wall keel 401, and the rear part of the positioning part 3051 is bent in the opposite direction towards the curtain wall keel 401. The positioning plate 305 is used to fix the installation mechanism 300.

[0024] It is worth mentioning that positioning posts 3053 are equidistantly arranged at the end of the positioning part 3051, and equidistant positioning holes 204 are symmetrically opened on the fixing plate 201. The size of the positioning posts 3053 is adapted to the size of the positioning holes 204, and the positioning posts 3053 are inserted into the positioning holes 204. When the curtain wall keel 401 is installed, the curtain wall keel 401 is moved backward by tightening the nut on the fixing screw 303. The rear end of the curtain wall keel 401 can press against the positioning plate 305. The curtain wall keel 401 first contacts the bend of the positioning part 3051, thereby causing the positioning plate 305 to rotate. This allows the positioning posts 3053 at the end of the positioning part 3051 to be inserted into the positioning holes 204, which can fix the position of the installation mechanism 300, prevent it from moving, and ensure its stability.

[0025] It is worth noting that the support part 3052 is bent into an arc shape towards the curtain wall keel 401, and the length of the support part 3052 is greater than the bending point of the positioning part 3051. A support opening 4013 is provided at the rear end of the curtain wall keel 401, and the end of the support part 3052 is inserted into the support opening 4013. When the positioning post 3053 is inserted into the positioning hole 204, the end of the support part 3052 can be inserted into the support opening 4013 at the rear end of the curtain wall keel 401, thereby providing auxiliary support for the curtain wall keel 401 and ensuring the stability of the installation of the curtain wall keel 401. When it is necessary to adjust the position of the curtain wall keel 401, simply loosen the nut on the fixing screw 303 to move the curtain wall keel 401 forward a certain distance, so that the positioning plate 305 disengages from the positioning hole 204 and the support opening 4013. This allows the installation mechanism 300 to be adjusted left and right on the support mechanism 200. After adjustment, tighten the nut on the fixing screw 303 again.

[0026] Working Principle: This embodiment provides an easily adjustable curtain wall steel keel support structure. During the installation and fixing stage, the embedded part 101 is first pre-fixed to the main building structure as the foundation of the entire support structure. The fixing plate 201 in the support mechanism is welded to the front end of the embedded part 101. The insertion groove 203 formed by the frame plate 202 and the fixing plate 201 provides installation space for the installation mechanism 300. The U-shaped plate 301 is inserted into the insertion groove 203 to achieve the initial connection between the installation mechanism 300 and the support mechanism 200. The curtain wall keel 401 is placed between the installation plates 302. The fixing screw 303 at the front end of the U-shaped plate 301 passes through the installation hole 4012 at the rear end of the curtain wall keel 401. The nut on the fixing screw 303 is tightened. The curtain wall keel 401 can be initially fixed to the installation mechanism 300. Simultaneously, the oblong hole 3021 on the installation plate 302 corresponds to the support hole 4011 on the side end of the curtain wall keel 401. The support screw 304 is inserted into it and engages with the nut, further enhancing the stability of the curtain wall keel 401 installation. When the curtain wall keel 401 is pulled backward by the fixing screw 303 and its nut, its rear end will press against the positioning plate 305. Since the front part of the positioning part 3051 is curved towards the curtain wall keel 401, the curtain wall keel 401 first contacts the bent part of the positioning part 3051, causing the positioning plate 305 to rotate around the rotation axis. This rotation causes the positioning post 3053 at the end of the positioning part 3051 to insert into the corresponding part of the fixing plate 201. The positioning plate 3053 is inserted into the positioning hole 204, thereby fixing the position of the mounting mechanism 300 on the support mechanism 200 and preventing it from moving left or right. At the same time, the support part 3052 moves with the rotation of the positioning plate 305, and its end is inserted into the support port 4013 at the rear end of the curtain wall keel 401, forming auxiliary support for the curtain wall keel 401 and further improving the stability of the overall structure. When it is necessary to adjust the position of the curtain wall keel 401, the operation is simple and efficient. Just loosen the nut on the fixing screw 303 to move the curtain wall keel 401 forward a certain distance. At this time, the squeezing force of the curtain wall keel 401 on the positioning plate 305 disappears, and the positioning plate 305 resets under its own characteristics or under the action of a slight external force, and the positioning post 3053 disengages from the positioning hole 204. The support part 3052 also exits from the support port 4013. Subsequently, the installation mechanism 300 can move freely left and right within the insertion slot 203 of the support mechanism 200 to adjust the left and right position of the curtain wall keel 401. The setting of the waist-shaped hole 3021 provides the possibility for adjusting the front and back position of the curtain wall keel 401. By loosening the support screw 304, the curtain wall keel 401 can move back and forth along the length direction of the waist-shaped hole 3021. After adjusting to the appropriate position, the nuts on the support screw 304 and the fixing screw 303 are tightened to complete the fixation. This support structure effectively solves the problems of time-consuming and labor-intensive adjustment methods and small adjustment range in traditional adjustment methods. While ensuring structural stability, it greatly improves the convenience and flexibility of curtain wall keel installation and adjustment.
