Description

Technical Field

[0001] The present invention relates to the technical field of construction curtain wall engineering construction, and particularly relates to a detachable cover plate construction device and construction method for a concrete curtain wall parapet wall. Background Art

[0002] As an outer enclosure decorative structure of a building main body, a building curtain wall usually does not have a load-bearing function. At the parapet wall part, when curtain walls are provided on both the inner and outer sides, a curtain wall cover plate needs to be added on the top of the parapet wall to complete the closing and meet the requirements of waterproofing, aesthetics, etc. The current common practice is to hoist an artistic concrete curtain wall cover plate to the top of the parapet wall, directly press it on the inner and outer curtain walls, and fix it to the parapet wall keel by welding. However, since the inner and outer curtain walls themselves are non-load-bearing members, the weight of the cover plate and the welding stress are likely to cause deformation of the curtain wall panel and even pose a risk of cracking; in addition, after the cover plate is welded to the keel to form a whole, if a single cover plate needs to be repaired, the entire row of cover plates must be removed or destructively cut. And the artistic concrete cover plate has special materials, and it is difficult to match the original appearance for replacement later, affecting the consistency of the building appearance.

[0003] In addition, there is another construction method for the curtain wall cover plate, which is to pre-open an installation groove on the parapet wall keel and fix it by inserting a cover plate angle steel into the groove. Although this avoids directly pressing on the curtain wall, the depth and position of the groove need to be strictly matched with the angle steel. Otherwise, the inner and outer edges of the cover plate cannot be flush, affecting the aesthetics. Moreover, it is difficult to finely adjust the position of the cover plate after installation. Not only is the adjustment ability poor, but also the construction accuracy requirements are extremely high. Otherwise, it will affect the construction quality and cannot ensure the force safety of the curtain wall.

[0004] Based on this, it is necessary to provide a curtain wall cover plate construction structure that can facilitate the construction of the curtain wall cover plate, does not exert pressure on the inner and outer vertical curtain walls, and is also convenient for adjusting and disassembling the position of a single cover plate. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a detachable cover plate construction device and construction method for a concrete curtain wall parapet wall, which effectively solves the problems of insufficient structural safety, difficult maintenance and replacement, low error tolerance, and poor adjustment ability in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A detachable cover construction device for the parapet of a concrete curtain wall, comprising a central seat, a V-shaped plate, a limiting member, an adjusting screw and a calibration device. The bottom of the V-shaped plate is hinged to the central seat. Limiting members are provided at the tops of the two plate bodies of the V-shaped plate for respectively fitting and pressing against the connecting members at the bottom of the cover plate, so that the cover plate is fixedly pressed above the V-shaped plate. The limiting member includes a positioning seat and an adjusting seat in a U-shaped structure, and the opening of the positioning seat faces the adjusting seat on the right side, and the opening of the adjusting seat faces upward. The connecting member is provided with a positioning plate and an adjusting plate. The positioning plate is in an L-shaped structure and can be inserted into the positioning seat. The adjusting plates are arranged in parallel at intervals and are respectively in close contact with the side walls of the adjusting seat. Swing seats are arranged on the left and right sides of the central seat. Screw holes are evenly formed on the left and right plate bodies of the V-shaped plate. The bottom of the adjusting screw is hinged to the swing seat, and its top is threadedly connected to the screw hole. By controlling the rotation of the adjusting screws on both sides, the V-shaped plate is driven to swing left and right with the rotating shaft as the central axis, so that the angle of the V-shaped plate is adjustable. A card slot is formed at the end of the limiting member, and the calibration device is adaptively clamped in the card slot. The output end of the calibration device points to the receiving point on the curtain wall. The inclination angle of the cover plate is calibrated by measuring the angle of the ray emitted by the calibration device towards the receiving point.

[0007] Further, the bottoms of the positioning seat and the adjusting seat are respectively fixedly arranged at the tops of the two plate bodies of the V-shaped plate. Both are in a U-shaped structure, and the opening of the positioning seat faces the adjusting seat on the right side, and the opening of the adjusting seat faces upward.

[0008] Further, the V-shaped plate is of an integral structure or is composed of two single plates and is hinged to the central seat. The central seats are arranged at intervals in the front-back direction. The rotating shaft is fixedly sleeved on the central seat, and the bottom of the V-shaped plate is rotatably sleeved on the rotating shaft.

[0009] Further, the calibration device is a laser locator, an infrared locator or a micro laser level.

[0010] Further, the bottoms of the central seat and the swing seat are both fixed on the parapet keel, and the parapet keel is arranged above the parapet.

[0011] Further, the bottom of the adjusting screw is hinged to the swing seat. The swing seat includes a bottom plate and a rotating seat. The rotating seat is welded and fixed to the bottom plate, and the bottom plate is installed on the parapet keel.

[0012] The present invention also provides a construction method for the detachable cover plate of the parapet of a concrete curtain wall, comprising the following steps: Step 1: Weld the bottom of the parapet keel to the angle steel at the top of the parapet in the horizontal direction, and fix its outer side to the vertical keel of the curtain wall; Step 2: Fix the swing seats at intervals on the keel, fix the center seat between the swing seats on the left and right sides, threadedly connect the adjusting screw rod with the V-shaped plate, and tilt and adjust the V-shaped plate at a preset angle. Step 3: Fix and install the calibration device at the end of the limiting member, make the laser ray emitted by the calibration device correspond to the receiving point on the curtain wall, and determine whether the tilt angle of the V-shaped plate meets the preset angle through the calibration device. If not, rotate the adjusting screw rods on both sides to adjust the V-shaped plate. Step 4: After the position of the V-shaped plate is calibrated, hoist the fabricated cover plate above the parapet keel, place the inner edge of the cover plate above the inner curtain wall, place the outer edge of the cover plate inside the outer curtain wall, and do not contact the inner and outer curtain walls. Step 5: Slowly lower the cover plate. First, misplace the fixing plate at the bottom of the cover plate with the limiting member on the V-shaped plate, make the positioning plate correspond to the inner cavity of the positioning seat, and the adjusting plate is misaligned and inserted into the adjusting seat. Step 6: After the vertical position of the cover plate is determined, adjust the position of the cover plate left and right. After ensuring that the distances between the inner and outer edges of the cover plate and the corresponding curtain walls meet the requirements, push the cover plate inward so that the adjusting plate on the cover plate abuts against the adjusting seat correspondingly, and at the same time, the positioning plate abuts against and contacts the inner cavity of the positioning seat, so that the cover plate is fixedly hung on the V-shaped plate. Step 7: After the position of the cover plate is confirmed, release the hoisting of the cover plate, and inject sealant between the cover plate and the inner and outer curtain walls; Step 8: Along the length extension direction of the parapet, complete the assembly of the remaining cover plates according to the methods in the above Steps 1-7, and inject weather-resistant sealant between adjacent cover plates to connect adjacent cover plates correspondingly.

[0013] Further, in Step 5, the manufacturing method of the cover plate includes the following steps: After cutting multiple steel plates, weld and fix L-shaped steel bars on each steel plate respectively, so that the extending directions of the steel bars correspond to the four corners of the steel plates respectively to form a fixing seat; After uniformly placing the fixing seats at the preset positions in the cover plate mold, pour concrete to form embedded parts, and remove the mold after molding; Then weld a positioning plate at the bottom of the left fixing seat and weld an adjusting plate at the bottom of the right fixing seat to complete the manufacturing of the cover plate.

[0014] The beneficial effects of the above technical solutions are as follows: The detachable cover plate construction device and construction method for the parapet of the concrete curtain wall proposed by the present invention enable the angle of the cover plate to be adjustable and convenient for maintenance. Through the hinge design of the V-shaped plate and the swing adjustment function of the adjusting screw rod in the present invention, the flexible adjustment of the tilt angle of the cover plate is realized. At the same time, the calibration device can accurately measure the tilt angle of the cover plate to ensure its precise correspondence with the receiving point of the curtain wall. The present invention not only improves the flexibility of construction, but also significantly improves the installation accuracy and reduces the rework problems caused by angle deviation.

[0015] The construction method of the present invention adopts a modular assembly process. Through the design of embedded parts and the quick hanging connection of limit parts, the installation steps of the cover plate are simplified. At the same time, the introduction of the calibration device ensures that the installation position and angle of each cover plate meet the design requirements, avoiding the problem of repeated adjustment caused by insufficient precision in traditional construction. Compared with the dependence on high-precision grooving and plugging processes in the prior art, the present invention significantly reduces the construction difficulty, simplifies the construction process, and improves the overall construction efficiency.

[0016] The articulated structure of the V-shaped plate of the present invention is combined with the swing adjustment function of the adjusting screw, so that the tilt angle of the cover plate can be flexibly adjusted according to actual needs. This design not only meets the installation requirements of different building structures, but also ensures the installation accuracy with the assistance of the calibration device. Secondly, the U-shaped structure of the limit part and the connecting parts (positioning plate and adjusting plate) at the bottom of the cover plate form a quick hanging connection mechanism, realizing the independent installation and disassembly of a single cover plate and avoiding the limitations of the traditional fixed structure.

[0017] The present invention takes the central seat as the fulcrum and drives the V-shaped plate to swing left and right through the adjusting screws on both sides, forming an adjustable basic support surface, which not only adapts to the slope requirements of different curtain walls, but also reduces construction errors through mechanical transmission; the U-shaped structures of the positioning seat and the adjusting seat cooperate with the L-shaped positioning plate and adjusting plate of the cover plate to form a two-way limit constraint, which not only ensures the horizontal stability of the cover plate, but also realizes self-locking fixation in the vertical direction through the friction force of the plugging contact surface, meeting the wind and earthquake resistance requirements without welding.

Detailed implementation manners

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners: Embodiment 1. This embodiment aims to provide a detachable cover plate construction device and construction method for the parapet wall of a concrete curtain wall, mainly used for hanging and installing the cover plate above the parapet wall. The construction device provided in this embodiment can not only adjust the angle of the cover plate above the parapet wall, but also support the independent adjustment and disassembly of a single cover plate, facilitating local maintenance without damaging adjacent components. In view of the limitations of the existing construction devices and construction methods for curtain wall cover plates, such as difficult maintenance and replacement, poor cover plate angle adjustment ability, and extremely high construction precision requirements for the grooving and plugging process, the detachable cover plate construction device for the parapet wall of a concrete curtain wall provided by the present invention combines the hinged structure of the V-shaped plate with the swing adjustment function of the adjusting screw, enabling the inclination angle of the cover plate to be flexibly adjusted according to actual needs. With the assistance of the calibration device, the installation precision is ensured. In addition, adjacent cover plates can be independently disassembled and installed without damaging adjacent components, improving the convenience of maintenance.

[0021] As Figures 1-6 shown, the detachable cover plate construction device for the parapet wall of a concrete curtain wall proposed in this embodiment includes a center seat 17, a V-shaped plate 13, a limiting member, an adjusting screw 16, a calibration device, etc. A parapet wall keel 2 is fixed at the top of the parapet wall 1. Specifically, an angle steel is fixed at the top of the parapet wall 1 by bolts, and the bottom of the parapet wall keel 2 is welded to the angle steel. The outer end of the parapet wall keel 2 is fixed to the vertical keel 6 on the outer curtain wall 4, and multiple are evenly fixed at the top of the parapet wall 1 along the length direction of the parapet wall 1. Each keel provides a support foundation for the center seat 17 and the swing seat 18 at the bottom of the adjusting screw 16 to assemble the V-shaped plate 13 between the cover plate 5 and the parapet wall 1, providing assembly support for the curtain wall cover plate 5. In this way, the acting force of the curtain wall cover plate 5 can be directly applied to the parapet wall keel 2, and then when the parapet wall keel 2 bears pressure, the acting force can be transmitted to the vertical keel 6 inside the curtain wall, avoiding direct stress on the inner and outer curtain walls 4.

[0022] The central seat 17 is fixedly arranged at the middle part above the keel at intervals in the front-back direction. A rotating shaft is fixedly sleeved inside the two central seats 17 in the front and back. The bottom of the V-shaped plate 13 is rotatably sleeved on the rotating shaft, and its opening faces upward. In this embodiment, the V-shaped plate 13 is of an integrally formed structure with a fixed angle. Limit members are fixedly arranged at the tops of the left and right plate bodies of the V-shaped plate 13 for respectively being adaptively pressed and connected with the connecting members at the bottom of the cover plate 5, so that the cover plate 5 is fixedly pressed above the V-shaped plate 13 to adjust and limit the laying position of the cover plate 5.

[0023] In the specific structure, as Figures 2-5 shown, in this embodiment, three groups of limit members are evenly arranged along the front-back direction at the top of the V-shaped plate 13 (in actual application, the number of arranged limit members and the length of the V-shaped plate are adapted to the length of the curtain wall cover plate to be assembled). Each group of limit members respectively includes a positioning seat 14 and an adjusting seat 15 in a U-shaped structure, and the positioning seat 14 and the adjusting seat 15 are correspondingly welded and fixed at the tops of the left and right plate bodies of the V-shaped plate 13. The opening of the positioning seat 14 faces the adjusting seat 15 on the right side, the opening of the adjusting seat 15 faces upward, and the inner cavity width of the adjusting seat 15 is greater than the inner cavity width of the positioning seat, so as to provide an adjustment margin for the construction of the curtain wall cover plate 5.

[0024] The connecting members of the curtain wall cover plate 5 are provided with a positioning plate 11 and an adjusting plate 12 corresponding to the above-mentioned positioning seat 14 and adjusting seat 15. Further, in this embodiment, the manufacturing method of the curtain wall cover plate 5 is as follows: after cutting multiple square steel plates according to the set dimensions, welding steel bars on each steel plate respectively, and bending the steel bars into an L-shaped structure so that the outward extending direction of the steel bars corresponds to the four corners of the steel plate respectively to form a fixing seat 10; after evenly placing the fixing seat 10 at the preset positions in the cover plate mold, pouring concrete to form an embedded part. In this embodiment, the fixing seat 10 is placed in a rectangular array in the cover plate 5 mold, and it is ensured that the distance between two adjacent fixing seats 10 in the left-right horizontal direction is adapted to the distance between the positioning seat 14 and the adjusting seat 15 at the top of the V-shaped plate 13. After the cover plate is formed and the mold is removed, then welding L-shaped positioning plates 11 at the bottoms of the left fixing seats 10 respectively, welding adjusting plates 12 at the bottoms of the right fixing seats 10 respectively, and the adjusting plates 12 are arranged in parallel at intervals. After the positioning plate 11 and the adjusting plate 12 are welded, the manufacturing of the cover plate 5 is completed.

[0025] With such a setting of the connecting members on the cover plate 5 and the limit members on the V-shaped plate 13 in this embodiment, when constructing the cover plate 5, after the angle and position of the V-shaped plate 13 are determined, first hoist the cover plate 5 above the limit members, so that the fixing plate at the bottom of the cover plate 5 is placed in a dislocation manner with the limit members on the V-shaped plate 13, make the positioning plate 11 correspond to the inner cavity of the positioning seat 14, and the adjusting plate 12 is inserted into the adjusting seat 15 in a dislocation manner. After the vertical position of the cover plate 5 is determined, adjust the position of the cover plate 5 left and right. After ensuring that the distances between the inner and outer edges of the cover plate 5 and the corresponding curtain wall meet the requirements, push the cover plate 5 inward, asFigure 6 As shown, the adjusting plate 12 on the cover plate is correspondingly abutted against the adjusting seat 15, and at the same time, the positioning plate 11 is in pressing contact with the inner cavity of the positioning seat 14, so that the cover plate 5 is fixedly hung on the V-shaped plate 13; this ensures the adjustment of minute deviations during the construction of the curtain wall cover plate 5 and realizes the precise positioning of the cover plate 5.

[0026] As Figure 5 shown, swing seats 18 are fixed on the parapet wall keels 2 on the left and right sides of the central seat 17. Screw holes are evenly formed on the left and right plate bodies of the V-shaped plate 13. The bottom of the adjusting screw 16 is hinged to the swing seat 18. In this embodiment, the swing seat 18 includes a rotating seat 181 and a bottom plate 182, wherein the rotating seat 181 is welded and fixed to the bottom plate 182, and the bottom plate 182 has a T-shaped structure and is fixed to the parapet wall keel 2 by bolts at the bottom. The bottom of the adjusting screw 16 is hinged to the rotating seat 181 through a rotating shaft. Thus, when adjusting the inclination angle of the V-shaped plate 13, the top support of the V-shaped plate 13 can be adapted by the swing of the adjusting screw 16.

[0027] The top of the adjusting screw 16 is threadedly connected in the screw hole. By controlling the rotation of the adjusting screws 16 on both sides, the V-shaped plate 13 is driven to swing left and right with the rotating shaft as the central axis, so that the angle of the V-shaped plate 13 is adjustable, thereby realizing the adaptive adjustment of the cover plate 5 hung on the top of the V-shaped plate 13.

[0028] As Figure 4 and 5 shown, a card slot 19 is formed at the end of the limiting member, and the calibration device is adaptively installed in the card slot 19. The output end of the calibration device points to the receiving point on the curtain wall. The inclination angle of the cover plate 5 is calibrated by measuring the angle of the ray emitted by the calibration device towards the receiving point. The above calibration device can be a laser locator, an infrared locator or a micro laser level, etc.

[0029] The present invention integrates a laser calibration device and a card slot of the limiting member, forms a closed-loop control route of "measurement - adjustment - fixation" by real-time monitoring of the inclination angle of the cover plate and feeding it back to the adjusting screw, and ensures the installation accuracy of the cover plate and the overall coordination of the curtain wall system. The angle of the V-shaped plate can be dynamically adjusted by the adjusting screw. Combining with the laser positioning function of the calibration device, high-precision control of the installation position of the cover plate can be realized; at the same time, the limiting member and the cover plate connecting member adopt a plug-in design, and a single cover plate can be independently disassembled and repaired without damaging adjacent components or the overall structure, significantly reducing the maintenance cost.

[0030] A detachable cover construction device for the parapet of a concrete curtain wall provided in this embodiment can assemble the curtain wall cover formed by artistic concrete onto the keel above the parapet. Sealant is injected at the edges adjacent to the inner and outer curtain walls on both sides of the cover. After the construction of the first cover is completed, the remaining covers are assembled in sequence along the length extension direction of the parapet according to the same construction method, and the adjacent covers are aligned to ensure the flatness of the cover laying. At the same time, weather-resistant sealant is injected between the adjacent covers. When maintenance is required for the target cover, only the separate cover component needs to be disassembled, without damaging other structures, reducing the maintenance difficulty and saving costs.

[0031] Example 2. Based on Example 1, this example further introduces the setting of the swing seat, as Figure 7 shown. The swing seats on both sides of the center seat are designed to slide. That is, a chute 23 is opened on the parapet keel, and a slider 24 is fixed at the bottom of the bottom plate of the swing seat. The slider is slidably installed in the chute. In this way, when adjusting to make the V-shaped plate inclined, it can be avoided that due to the fixed position of the adjusting screw rod, the screw rod cannot be threadedly connected with the screw hole on the V-shaped plate. Therefore, with the setting of the swing seat in this example, the positions of the swing seat and the adjusting screw rod can follow the change of the angle of the V-shaped plate, so that the adjusting screw rod is always adapted to the screw hole on the V-shaped plate. After the adjustment of the V-shaped plate is completed, the position of the swing seat can be fixed by a set screw or a bolt.

[0032] Example 3. Based on Examples 1 and 2, as Figure 8 shown, the adjusting screw rod can also be a telescopic sleeve rod structure (this is prior art and will not be described in detail here). The bottom of the telescopic sleeve rod is hinged to the swing seat, and a top plate is fixed at the top, and the V-shaped plate is supported by the top plate by pressing.

[0033] Example 4. This example is basically the same as Example 1, except that in this example, the V-shaped plate is composed of two single plates, similar to a hinge structure, and is hinged to the center seat in a split structure, so as to be easily adapted to the adjusting screw rods on both sides to achieve quick adjustment of the angle of the V-shaped plate.

[0034] Example 5. Based on the above Examples 1-4, this example provides a construction method for the detachable cover of the concrete curtain wall parapet, which specifically includes the following steps: Step 1: Weld the bottom of the parapet keel 2 to the angle steel at the top of the parapet 1 along the horizontal direction, and fix its outer side to the vertical keel 6 of the curtain wall. Step 2: Fix the swing seats 18 at intervals on the keel, fix the center seat 17 between the swing seats 18 on the left and right, threadedly connect the adjusting screw rods 16 with the V-shaped plate 13, and adjust the V-shaped plate 13 to be inclined at a preset angle. Step 3: Fix and clamp the calibration device at the end of the limiting member, so that the laser ray emitted by the calibration device corresponds to the receiving point on the curtain wall. Determine whether the inclination angle of the V-shaped plate 13 meets the preset angle through the calibration device. If not, rotate the adjusting screws 16 on both sides to adjust the V-shaped plate 13; Step 4: After the position of the V-shaped plate 13 is calibrated, hoist the fabricated cover plate 5 above the parapet wall keel 2, so that the inner edge of the cover plate 5 is placed above the inner curtain wall 3, and the outer edge of the cover plate 5 is placed inside the outer curtain wall 4, and does not contact the inner and outer curtain walls; Step 5: Slowly lower the cover plate 5. First, misplace the fixing plate at the bottom of the cover plate 5 and the limiting member on the V-shaped plate 13, so that the positioning plate 11 corresponds to the inner cavity of the positioning seat 14, and the adjusting plate 12 is misaligned and inserted into the adjusting seat 15; Step 6: After the vertical position of the cover plate 5 is determined, adjust the position of the cover plate 5 left and right. After ensuring that the distances between the inner and outer edges of the cover plate 5 and the corresponding curtain walls meet the requirements, push the cover plate 5 inward, so that the adjusting plate 12 on the cover plate 5 abuts against the adjusting seat 15 correspondingly, and at the same time the positioning plate 11 abuts against and contacts the inner cavity of the positioning seat 14, so that the cover plate 5 is fixedly hung on the V-shaped plate 13; Step 7: After the position of the cover plate 5 is confirmed, release the hoisting of the cover plate 5, and apply sealant between the cover plate 5 and the inner and outer curtain walls; Step 8: Along the length extension direction of the parapet wall 1, complete the assembly of the remaining cover plates 5 according to the methods of the above steps 1-7, and apply weather-resistant glue between adjacent cover plates 5 to connect adjacent cover plates 5 correspondingly.

[0035] The construction method of the detachable cover plate for the parapet wall of the concrete curtain wall provided by the present invention enables each cover plate to be independently disassembled and installed without damaging adjacent components. This modular design not only reduces the maintenance difficulty, but also saves time and labor costs, and is particularly suitable for building curtain wall projects that require frequent maintenance.

[0036] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.

Step 6: After determining the vertical position of the cover plate, adjust the position of the cover plate left and right. After ensuring that the distances between the inner and outer edges of the cover plate and the corresponding curtain wall meet the requirements, push the cover plate inward so that the adjusting plate on the cover plate abuts against the adjusting seat correspondingly. At the same time, the positioning plate is in pressure contact with the inner cavity of the positioning seat, so that the cover plate is fixedly hung on the V-shaped plate. Step 7: After confirming the position of the cover plate, release the hoisting of the cover plate and inject sealant between the cover plate and the inner and outer curtain walls. Step 8: Along the length extension direction of the parapet wall, complete the assembly of the remaining cover plates according to the methods of the above Steps 1-7, and inject weather-resistant sealant between adjacent cover plates so that the adjacent cover plates are correspondingly connected together.

9. The construction method of the detachable cover plate for the parapet of the concrete curtain wall according to claim 8, characterized in that: In Step 5, the manufacturing method of the cover plate includes the following steps: After cutting multiple steel plates, fixedly weld L-shaped steel bars on each steel plate so that the extending directions of the steel bars correspond to the four corners of the steel plate respectively to form a fixing seat; after uniformly placing the fixing seat at a preset position in the cover plate mold, pour concrete to form an embedded part, and remove the mold after molding; then weld a positioning plate at the bottom of the left fixing seat and weld an adjusting plate at the bottom of the right fixing seat to complete the manufacture of the cover plate.
