Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a structure of a building curtain wall embedded part. Background Art

[0002] In modern building curtain wall projects, the channel-shaped embedded part, as a key component connecting the curtain wall structure and the building main body, plays an important role in bearing loads such as wind force and earthquake. The channel-shaped embedded part is usually welded by a steel channel profile and anchor bars. Before pouring concrete for the building main body, it needs to be buried in the structure in advance. To ensure the stable installation of the embedded part, a framework is usually used to fill and install the embedded part during construction. Binding steel bars are placed in the framework, and the embedded part is connected to the bottom of the framework through the binding steel bars. Then the framework is connected to the formwork through the binding steel bars, and finally cement is poured. In the field of modern building curtain wall construction, the channel-shaped embedded part, as the core component for realizing the reliable connection between the curtain wall structure and the building main body, needs to be accurately embedded before concrete pouring. In current engineering practices, there are mainly two ways for its installation and transportation: one is to transport the channel-shaped embedded part and the installation framework as a whole to the formwork installation position; the other is to transport the embedded part and the framework separately and then combine and fix them on-site. In the first overall transportation method, due to the long length of the anchor bars of the channel-shaped embedded part, the anchor bars are extremely easy to hook on sundries such as temporary pipelines, scaffolding members, and stacked building materials at the construction site during handling, and may even cause deformation of the embedded part and fracture of the anchor bars due to hooking, seriously affecting its mechanical properties; while the second separate transportation method reduces the transportation difficulty, but additional steps for combining, positioning, and connecting the embedded part and the framework are required at the construction site, prolonging the installation period and reducing the construction efficiency.

Specific embodiments

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. Embodiment 1

[0036] Referring to Figures 1 - 15 , this is the first embodiment of the present invention. This embodiment provides a building curtain wall embedded part structure. The building curtain wall embedded part structure includes an assembly component 2, which solves the problems of inconvenient transportation due to the long length during overall transportation and low efficiency during separate transportation in the prior art. At the same time, it can also improve the stability of the steel channel section 12 during assembly transportation and the sealing performance of the frame body 11 during pouring.

[0037] The main structure 1 includes a frame 11, a steel channel profile 12 is provided at the bottom of the frame 11, a docking block 13 is fixedly connected to one side of the frame 11, a fixing member 14 is provided on the top of the docking block 13, a template 15 is provided on one side of the docking block 13, and a docking groove 16 is opened on one side of the template 15; and The assembly component 2 includes a through slot 21 opened at the bottom of the frame 11, and a guide frame 22 is fixedly connected to the bottom of the inner cavity of the frame 11. The top of the steel channel profile 12 passes through the through slot 21 and extends into the guide frame 22. The inner cavity of the through slot 21 is provided with a shearing piece 23, and the inner cavity of the through slot 21 is provided with an embedding slot 24 on all sides. The inner cavity of the embedding slot 24 is fixedly connected to a sealing airbag 25. The bottom plate of the frame 11 is provided with a cavity 26, and the inner cavity of the cavity 26 is provided with a connecting piece 27. Frame covers 28 are provided on both sides of the top of the frame 11. The outer sides of the frame covers 28 are hinged to the frame 11, and a protective piece 29 is provided on one side of the frame cover 28.

[0038] In the main structure 1, the frame 11, the steel channel profile 12 and the template 15 are all existing technologies, which can be clearly understood by those skilled in the art and will not be described in detail. After the concrete is poured into the main building, the steel channel profile 12 will be firmly embedded in the reinforced concrete, becoming the key load-bearing component for connecting the curtain wall and the main building. The docking block 13 and the fixing member 14 cooperate to achieve a quick connection with the template 15. The docking groove 16 provides positioning for the docking block 13. In the assembly component 2, the first shear screw 14-4, the second shear screw 23-1 and the sealing airbag 25 are all existing technologies, which can be clearly understood by those skilled in the art and will not be described in detail. The through groove 21 is used for the steel channel profile 12 to pass through and install, and the guide frame 22 limits and guides the steel channel profile 12. The first shear screw 14-4 and the second shear screw 23-1 are used to fix the steel channel profile 12. The two shear screws 23-1 will actively break at the groove when the force exceeds the preset fracture threshold, and are used to fix the docking block 13 before pouring and separate the frame 11 and the steel trough profile 12 after pouring; the sealing airbag 25 can prevent concrete leakage; the cavity 26 and the connecting piece 27 are used to realize automatic fixation of the steel trough profile 12 and the frame 11; the frame cover 28 and the protective piece 29 can prevent concrete from entering the frame 11, which is convenient for later cleaning. During assembly and transportation, the steel trough profile 12 is partially located in the frame 11, which can reduce the exposed volume and facilitate transportation; the initial connection and movement between the frame 11 and the steel trough profile 12 can improve the transportation efficiency; at the same time, the limit of the guide frame 22 improves the movement stability, effectively solving the problems of the overall transportation difficulty and the extension of the installation period during separate transportation in the existing technology. Example 2

[0039] Reference Figures 1 - 15 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0040] Specifically, the fixing member 14 includes a swing rod 14-1 hinged to the top of the docking block 13. A fixing groove 14-2 is formed on one side of the inner cavity of the docking groove 16 and is matched with the swing rod 14-1. A cross-shaped fixing member 14-3 is fixedly connected to one side of the swing rod 14-1. An installation groove is formed at the bottom of the docking block 13. A first shear screw 14-4 is fixedly connected to the bottom of the inner cavity of the docking groove 16 and is matched with the installation groove.

[0041] The fixing member 14 is matched with the fixing groove 14-2 in the docking groove 16 through the swing rod 14-1 hinged to the top of the docking block 13 to fix the top of the docking block 13. The cross-shaped fixing member 14-3 increases the contact area with the template 15 and improves the fixing stability. The first shear screw 14-4 is matched with the installation groove at the bottom of the docking block 13 to facilitate the fixing of the bottom of the docking block 13. During the docking process of the docking block 13 and the template 15, the components of the fixing member 14 are linked. Compared with the traditional method of fixing with tied steel bars, the operation is more convenient and efficient. When the docking block 13 is inserted into the docking groove 16, the bottom is initially clamped with the first shear screw 14-4, and then the swing rod 14-1 is rotated to cooperate with the fixing groove 14-2 to quickly fix from the top and bottom directions. This linked design reduces the installation steps, shortens the installation time, and improves the construction efficiency.

[0042] Specifically, the shearing member 23 includes second shear screws 23-1 fixedly connected to both sides of the inner cavity of the through groove 21. Shearing grooves 23-2 are formed on both sides of the steel channel profile 12 and are matched with the second shear screws 23-1.

[0043] The second shear screws 23-1 of the shearing member 23 are matched with the shearing grooves 23-2 on the steel channel profile 12. After the steel channel profile 12 is installed in place, the steel channel profile 12 can be supported by the second shear screws 23-1 and fixed at the same time. It has a linked relationship with the connecting member 27. When the connecting member 27 drives the steel channel profile 12 to descend to the specified position, the second shear screws 23-1 enter the shearing grooves 23-2. As the steel channel profile 12 continues to be stressed, the shearing grooves 23-2 and the second shear screws 23-1 are clamped, so that the alignment of the clamping block 27-8 and the clamping groove 27-10 is achieved, facilitating subsequent fixing. This linkage ensures the standardization and accuracy of the installation of the steel channel profile 12 and improves the stability of the overall structure.

[0044] Specifically, the connecting member 27 includes an abutting rod 27-1 slidably connected to one side of the docking block 13. One side of the abutting rod 27-1 penetrates through the docking block 13 and the frame body 11 and extends into the cavity 26. A movable plate 27-2 is fixedly connected to the surface of the abutting rod 27-1. Movable rods 27-3 are hinged to both sides of the movable plate 27-2. One side of the movable rod 27-3 away from the movable plate 27-2 is hinged to a fixing plate 27-4. A triggering portion 27-5 is provided at the bottom of the fixing plate 27-4. A supporting block 27-6 is fixedly connected to the top of the fixing plate 27-4. Limiting portions 27-7 are provided on both sides of the supporting block 27-6. A clamping block 27-8 is fixedly connected to one side of the supporting block 27-6 close to the guiding frame 22. Through grooves 27-9 are formed in both sides of the guiding frame 22. Card slots 27-10 are formed in both sides of the steel channel profile 12 and are matched with the clamping block 27-8.

[0045] In the connecting member 27, when the docking block 13 moves, the abutting rod 27-1 is affected by the bending guide plate 27-11, driving the movable plate 27-2, the movable rod 27-3, the fixing plate 27-4, the supporting block 27-6 and the clamping block 27-8 to move. Through the cooperation of the clamping block 27-8 on the supporting block 27-6 and the card slot 27-10 of the steel channel profile 12, the fixation of the steel channel profile 12 and the frame body 11 is realized; when the docking block 13 is inserted into the docking groove 16, the abutting rod 27-1 moves to trigger a series of linkages. First, the steel channel profile 12 loses the support of the clamping block 27-8 and descends. After being installed in place, the clamping block 27-8 can be reinserted into the card slot 27-10 for fixation. This linkage mechanism realizes the automation of the installation of the steel channel profile 12, eliminating the need for manual adjustment and fixation multiple times, reducing the installation operation steps, improving the installation efficiency, and ensuring the stability and reliability of the fixation at the same time.

[0046] Specifically, a bending guide plate 27-11 is provided on the other side of the abutting rod 27-1. One side of the bending guide plate 27-11 is fixedly connected to the inner cavity of the docking groove 16. A spring 27-12 is sleeved on the other side of the surface of the abutting rod 27-1. One side of the spring 27-12 is fixedly connected to the movable plate 27-2. The other side of the spring 27-12 is fixedly connected to the inner cavity of the cavity 26.

[0047] The movement direction of the abutting rod 27-1 is controlled by the bending guide plate 27-11 on the other side, and the spring 27-12 provides the reset power for the movable plate 27-2. During the docking process of the docking block 13 and the template 15, the spring 27-12 is first compressed and then releases its elastic potential energy, driving the clamping block 27-8 to snap into the clamping groove 27-10, realizing the firm fixation of the steel channel profile 12. At the same time, it ensures that the structure can be operated repeatedly. The linkage of the spring 27-12 with other components makes the fixation process of the steel channel profile 12 more stable and self-adaptive. At the initial stage of the movement of the docking block 13, the spring 27-12 compresses and stores energy to provide power for subsequent fixation; when the docking is completed, the spring 27-12 releases energy to drive the clamping block 27-8 to accurately snap into the clamping groove 27-10. This kind of linkage not only ensures the fixation effect, simplifies the operation process, reduces manual intervention, but also improves the construction efficiency and the accuracy of fixation.

[0048] Among them, the spring 27-12 adopts a commonly used elastic component in the field, and its specific specifications can be flexibly selected and adapted by technicians according to the actual engineering requirements. This is prior art and will not be elaborated here.

[0049] Specifically, the triggering part 27-5 includes a triggering rod 27-51 fixedly connected to the bottom of the fixing plate 27-4. On the side of the triggering rod 27-51 away from the fixing plate 27-4, a piston 27-52 is fixedly connected. The surface of the piston 27-52 is slidably connected with a sleeve 27-53. One side of the sleeve 27-53 is connected to the sealed airbag 25 through a pipeline, and the bottom of the sleeve 27-53 is fixedly connected to the inner cavity of the cavity 26.

[0050] The gas path system composed of the triggering rod 27-51, the piston 27-52, the sleeve 27-53 and the pipeline of the triggering part 27-5 is linked with the connecting part 27. When the fixing plate 27-4 moves, the gas in the sleeve 27-53 is pressed into the sealed airbag 25, causing it to expand and seal the through groove 21, preventing concrete from entering the frame 11 through the gap, ensuring the cleanliness inside the frame 11 and facilitating subsequent use. When the connecting part 27 drives the fixing plate 27-4 to complete the fixation of the steel channel profile 12, the triggering part 27-5 acts synchronously to automatically seal the through groove 21. This kind of linkage ensures the timeliness and effectiveness of the sealing and prevents concrete leakage.

[0051] Specifically, the limiting part 27-7 includes limiting grooves 27-71 opened on both sides of the bottom of the inner cavity of the frame 11. On both sides of the inner cavity of the limiting grooves 27-71, rolling wheels 27-72 are fixedly connected. Rolling grooves 27-73 are opened on both sides of the supporting block 27-6 and are matched with the rolling wheels 27-72.

[0052] The limiting groove 27-71, the rolling wheel 27-72, and the rolling groove 27-73 of the limiting part 27-7 support and limit the support block 27-6. The rolling wheel 27-72 reduces the friction when the support block 27-6 moves, and is linked with other components of the connecting piece 27 to ensure the smooth movement of each component of the connecting piece 27. During the movement of the support block 27-6 along with other components of the connecting piece 27, the limiting part 27-7 ensures that it moves along a predetermined trajectory and avoids deviation. The setting of the rolling wheel 27-72 reduces the frictional resistance, makes the linkage process smoother, reduces component wear, and improves the stability and reliability of the entire fixing process.

[0053] Specifically, the protective part 29 includes a driving gear 29-1 rotatably connected to the bottom of one side of the frame body 11. A sliding groove 29-2 is formed on the other side of the template 15, and a toothed plate 29-3 is fixedly connected to one side of the inner cavity of the sliding groove 29-2 close to the docking groove 16.

[0054] The driving gear 29-1 of the protective part 29 meshes with the toothed plate 29-3 on the template 15. When the frame body 11 is docked with the template 15, the driving gear 29-1 rotates to drive the driven gear 29-4 to rotate, and then the rotating rod 29-5 drives the frame cover 28 to rotate, realizing the closing of the top of the frame body 11, preventing concrete from entering the frame body 11, and reducing the later cleaning work. This linkage method cleverly utilizes the mechanical movement during the docking of the frame body 11 and the template 15, without additional power and operation, and automatically completes the protection of the top of the frame body 11. When the docking block 13 is inserted into the docking groove 16, the movement of the frame body 11 drives the driving gear 29-1 to mesh and rotate with the toothed plate 29-3, thereby linking the frame cover 28 to close, avoiding the forgetting or mistakes that may occur in manual operation, effectively protecting the internal structure of the frame body 11, and improving the convenience of construction and the protection effect of the embedded parts.

[0055] Specifically, a driven gear 29-4 is meshed with the top of the driving gear 29-1. One side of the driven gear 29-4 is fixedly connected with a rotating rod 29-5. One side of the rotating rod 29-5 penetrates through the frame body 11 and is fixedly connected with the frame cover 28.

[0056] Driven by the driving gear 29-1, the driven gear 29-4 controls the rotation of the frame cover 28 through the rotating rod 29-5. The protective cover 29-6 protects the driven gear 29-4 from being eroded by concrete or interfered by sundries, ensuring the long-term stable operation of the protective part 29. The driven gear 29-4, the driving gear 29-1, the rotating rod 29-5, and the frame cover 28 form a linkage system. During the docking process of the frame body 11 and the template 15, the rotation of the driving gear 29-1 is accurately transmitted to the driven gear 29-4, and then the frame cover 28 is accurately driven to close through the rotating rod 29-5.

[0057] Working principle: During the transportation stage, the anchor rod at the bottom of the steel channel profile 12 is inserted into the guiding frame 22 within the frame body 11. Subsequently, the bottom of the steel channel profile 12 is supported by the clamping block 27-8, achieving the preliminary connection between the frame body 11 and the steel channel profile 12. Part of the steel channel profile 12 is received within the frame body 11, reducing the exposed volume, facilitating transportation and improving the conveying efficiency. At the same time, the guiding frame 22 positions the steel channel profile 12 to ensure its stability during movement. When moving to the formwork 15, the docking block 13 is inserted into the docking groove 16. After the installation groove at the bottom of the docking block 13 is clamped with the first shear screw 14-4, rotate the swing rod 14-1 so that it penetrates the fixing groove 14-2 and contacts the formwork 15 through the cross fastener 14-3, realizing the top-bottom fixation of the docking block 13. During this process, the movement of the docking block 13 drives the abutting rod 27-1 to contact the bending guide plate 27-11. The movement of the abutting rod 27-1 compresses the spring 27-12, and at the same time drives the movable plate 27-2, the movable rod 27-3, the fixing plate 27-4, the support block 27-6 and the clamping block 27-8 to move, causing the steel channel profile 12 to lose the support of the clamping block 27-8 and descend, enabling the second shear screw 23-1 to enter the shear groove 23-2. When the second shear screw 23-1 is clamped with the top of the inner cavity of the shear groove 23-2, the steel channel profile 12 stops descending. At this time, the clamping block 27-8, the through groove 27-9 and the card slot 27-10 are aligned. As the docking block 13 slides to the bottom of the docking groove 16, the abutting rod 27-1 disengages from the bending guide plate 27-11, and the spring 27-12 releases its elastic potential energy, causing the movable plate 27-2, the movable rod 27-3, the fixing plate 27-4, the support block 27-6 and the clamping block 27-8 to reset in sequence, thereby driving the clamping block 27-8 to pass through the through groove 27-9 and be clamped in the card slot 27-10, completing the firm fixation of the steel channel profile 12 and the frame body 11. At the same time, the movement of the fixing plate 27-4 drives the trigger rod 27-51 and the piston 27-52 to move, pressing the gas in the sleeve 27-53 into the sealed airbag 25 to make it expand, sealing the through groove 21 to prevent concrete leakage.

[0058] With the connection of the docking block 13 and the docking groove 16, the frame body 11 drives the driving gear 29-1 into the sliding groove 29-2 and meshes with the toothed plate 29-3. The rotation of the driving gear 29-1 drives the driven gear 29-4 and the rotating rod 29-5, causing the frame cover 28 to rotate and close the top of the frame body 11 to prevent concrete from entering the interior of the frame body 11. Thereafter, concrete is poured, and the steel channel profile 12 will be firmly embedded in the reinforced concrete, becoming the foundation for the connection between the curtain wall and the building main body. After pouring is completed, rotate the swing rod 14-1 to disengage the cross-shaped fastener 14-3 from the fixing groove 14-2, move the formwork 15 to overcome the force of the first shear screw 14-4 to remove the formwork, and then move the frame 11 upward to overcome the force of the second shear screw 23-1 to remove the frame 11, realizing demoulding. At this time, the steel trough profile 12 has been firmly embedded and can be used for installing curtain wall keels subsequently. Embodiment 3

[0059] Refer to Figure 14 and Figure 15 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0060] Specifically, a protective cover 29-6 is provided on the surface of the driven gear 29-4, and the bottom of the protective cover 29-6 is fixedly connected to the frame 11.

[0061] The setting of the protective cover 29-6 effectively protects the driven gear 29-4, prevents it from being damaged in a complex construction environment, ensures the reliability of the transmission between the driving gear 29-1 and the driven gear 29-4, and further ensures that the frame cover 28 can normally realize the opening and closing functions and play a protective role. The existence of the protective cover 29-6 ensures the reliability of the linkage system, avoids transmission failure caused by external factors, ensures that the frame cover 28 can work normally during each docking, continuously plays a protective role, reduces the maintenance cost and the risk brought by the failure of protection.
