Description

Technical Field

[0001] This application relates to the field of building component connection technology, and in particular to an adjustable-angle precast concrete exterior wall connection structure. Background Technology

[0002] As is well known, precast concrete exterior wall panels have been widely used in various construction projects such as residential buildings, commercial buildings, and industrial plants due to their advantages such as high construction efficiency, high degree of industrialization, energy saving and environmental protection. The connection structure of precast concrete exterior wall panels is a core component that ensures the overall stability, sealing and safety of the building. Its design rationality directly affects the construction quality and long-term performance of the building.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN220978443U discloses a connection structure for precast concrete exterior wall panels. This structure mainly consists of wall panels, mounting holes, a butt joint structure, and a convenient installation structure. The butt joint structure enables the initial splicing of two wall panels, and an adhesive is injected using a grouting machine to enhance the connection strength. This solves, to a certain extent, the problems of cumbersome construction and low efficiency of traditional connection methods.

[0004] Regarding the aforementioned technologies, the applicant has found that existing precast concrete exterior wall panel connection structures are mostly designed with fixed angles. Their mating structures have a single adaptability angle, which can only achieve splicing at 0° or a specific angle. It is difficult to flexibly adjust the connection angle between wall panels according to actual construction needs. At the same time, problems such as excessively large splicing gaps and poor connection sealing are prone to occur. Subsequent efforts are required to fill a large amount of sealing material or rework and adjust to make up for these issues, which further reduces construction efficiency and connection reliability.

[0005] Therefore, it is necessary to propose an adjustable-angle precast concrete exterior wall connection structure. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable-angle precast concrete exterior wall connection structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable-angle precast concrete exterior wall connection structure, comprising:

[0009] Two connecting plates, each of which has a mounting groove;

[0010] Multiple positioning bolts are rotatably disposed within the connecting plate, and the positioning bolts are adapted to the mounting grooves;

[0011] Two connecting components are disposed between two connecting plates. Each connecting component includes a support plate one and a support plate two. The support plate one and the support plate two are symmetrically disposed at one end of the connecting plates. A rotating shaft is rotatably disposed on the support plate two. The rotating shaft extends to the outside of the support plate one through a connecting hole. A connecting block is fixedly sleeved on the outside of the rotating shaft. One end of the connecting block is connected to the outer wall of the other connecting plate.

[0012] A limiting component is disposed on the rotating shaft and is used to effectively limit the rotation shaft;

[0013] The mounting assembly is disposed on two connecting plates and is used to fix the two connecting plates in the use position.

[0014] As a further embodiment of this utility model: the limiting component includes a turntable, which is fixedly connected to a rotating shaft, and a positioning rod is vertically slidably connected inside the turntable. The support plate has multiple limiting holes, and a limiting ring is provided inside the limiting holes. The limiting ring is adapted to the positioning rod.

[0015] As a further embodiment of this utility model: the mounting assembly includes four mounting plates, which are symmetrically arranged on the outer walls of the two connecting plates, and each mounting plate has a threaded ring inside, with mounting bolts threaded into the threaded ring.

[0016] As a further improvement of this utility model: multiple through holes are provided in both connecting plates, and a constraint ring is provided in the through holes. The positioning bolt is threaded to the connecting plate through the constraint ring.

[0017] As a further improvement of this utility model, rubber pads are provided in the mounting grooves of both connecting plates.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The connecting component between the two connecting plates, through the cooperation of the pivot on the second support plate and the connecting block, can drive the connecting plate to rotate flexibly, breaking through the limitation of single-angle splicing. It can adapt to different connection angles according to actual construction needs, meeting the splicing requirements of complex scenarios such as irregular walls or pitched roofs. The limiting component on the pivot, through the positioning rod in the turntable, is inserted into the limiting hole of the first support plate, which can quickly lock the adjusted angle and ensure the long-term stability of the connection structure. The rubber pad in the mounting groove of the connecting plate can fill the splicing gap, greatly improving the connection sealing. The positioning bolt is connected to the connecting plate by the thread through the constraint ring, enhancing the connection tightness with the exterior wall panel and further reducing the splicing gap. The four symmetrical mounting plates of the mounting component, with threaded rings and mounting bolts, facilitate the quick fixing of the connecting plate to the exterior wall panel, simplifying the construction process. Its overall structure is relatively simple. Compared with the existing technology, its overall structure realizes the functions of "adjustable angle, stable limiting, sealing and leak prevention, and convenient installation", thereby significantly improving construction efficiency and connection reliability, and thus adapting to the diverse construction needs of modern building exterior walls, with good overall practicality.

[0025] 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.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 In this embodiment of the invention, an adjustable-angle precast concrete exterior includes:

[0028] Two connecting plates 1, each of which has a mounting groove;

[0029] Multiple positioning bolts 2 are rotatably disposed within the connecting plate 1, and the positioning bolts 2 are adapted to the mounting groove;

[0030] Two connecting components are provided, each located between two connecting plates 1. Each connecting component includes a first support plate 3 and a second support plate 4. The first support plate 3 and the second support plate 4 are symmetrically arranged at one end of the connecting plate 1. A rotating shaft 5 is rotatably mounted on the second support plate 4. The rotating shaft 5 extends to the outside of the first support plate 3 through a connecting hole. A connecting block 6 is fixedly sleeved on the outside of the rotating shaft 5. One end of the connecting block 6 is connected to the outer wall of the other connecting plate 1.

[0031] A limiting component is provided on the rotating shaft 5, which is used to effectively limit the rotating shaft 5;

[0032] The mounting components are mounted on the two connecting plates 1 and are used to fix the two connecting plates 1 in the usage position.

[0033] This adjustable-angle precast concrete exterior wall connection structure, when in use, is operated by holding one of the connection plates 1 with both hands and slowly rotating it around the pivot 5 on the support plate 2 4. The pivot 5 drives the externally fixed connection block 6 to rotate synchronously, thereby adjusting the angle between the two connection plates 1. During the rotation, the angle parameters on the construction drawings are compared in real time until the angle of the two connection plates 1 is completely consistent with the design requirements. At this point, the rotation is stopped. Then, the operator pulls the positioning rod 8 inside the turntable 7 upwards, aligning it with the corresponding angle limit hole on the support plate 1 3, and slowly releases the positioning rod. Rod 8, the positioning rod 8, is inserted into the limiting hole under the action of gravity to complete the limiting lock of the rotating shaft 5. After locking, gently push the connecting plate 1 to confirm that the angle is not loose. Then, pass the mounting bolt 12 of the mounting component through the threaded ring 11 in the mounting plate 10, align it with the preset mounting hole of the precast concrete exterior wall panel, and use a tool to tighten the mounting bolt 12 clockwise and symmetrically until the connecting plate 1 and the exterior wall panel are tightly fitted. At the same time, rotate the positioning bolt 2, and with the assistance of the constraint ring 13, make the positioning bolt 2 penetrate into the interior of the exterior wall panel to further enhance the tightness of the connection between the connecting plate 1 and the exterior wall panel and avoid gaps at the splice.

[0034] exist Figure 1-3 In the middle: the limiting component includes a turntable 7, which is fixedly connected to the rotating shaft 5, and a positioning rod 8 is vertically slidably connected inside the turntable 7. Multiple limiting holes are opened on the support plate 3, and a limiting ring 9 is set in the limiting hole. The limiting ring 9 is adapted to the positioning rod 8.

[0035] This adjustable-angle precast concrete exterior wall connection structure allows the turntable 7 to rotate synchronously with the rotating shaft 5. Operators can quickly align the limiting holes at different angles using the sliding positioning rod 8, thus flexibly locking the angle of the connecting plate 1. The limiting ring 9 prevents wear caused by direct friction between the positioning rod 8 and the wall of the limiting hole, while ensuring that the positioning rod 8 fits tightly against the hole wall, preventing loosening due to vibration after angle locking, and ensuring the long-term angular stability of the connection structure. Angle fixing can be completed without the need for additional complex tools.

[0036] exist Figure 1-4 The mounting assembly includes four mounting plates 10, which are symmetrically arranged on the outer walls of the two connecting plates 1. Each mounting plate 10 has a threaded ring 11, and a mounting bolt 12 is threaded into the threaded ring 11.

[0037] This adjustable-angle precast concrete exterior wall connection structure, through the setting of four symmetrically distributed mounting plates 10, ensures that the connection between the connecting plate 1 and the exterior wall panel is evenly stressed, avoiding excessive local stress that could cause deformation of the connecting plate 1; the threaded ring 11 enhances the connection stability between the mounting bolt 12 and the mounting plate 10, preventing the bolt from stripping after long-term use; the mounting bolt 12 can be quickly installed and removed through the threaded ring 11, simplifying the fixing process between the connecting plate 1 and the exterior wall panel and improving construction efficiency.

[0038] exist Figure 1-4 In the middle: both connecting plates 1 have multiple through holes, and a constraint ring 13 is installed in each through hole. The positioning bolt 2 is threaded to the connecting plate 1 through the constraint ring 13. Rubber pads 14 are installed in the mounting grooves of both connecting plates 1.

[0039] It should also be noted that the constraint ring 13 can protect the inner wall of the through hole of the connecting plate 1, avoid repeated disassembly and assembly of the positioning bolt 2 or long-term stress causing wear of the through hole thread, ensure that the positioning bolt 2 is tightly connected to the connecting plate 1, and further enhance the fixing effect between the connecting plate 1 and the outer wall panel; the rubber pad 14 in the installation groove can tightly fill the splicing gap between the connecting plate 1 and the outer wall panel, effectively improve the connection sealing performance, and reduce the subsequent sealing material filling process and amount.

[0040] The implementation principle of an adjustable-angle precast concrete exterior wall connection structure according to an embodiment of this application is as follows: First, the operator confirms the status of each component, checks that the turntable 7 and positioning rod 8 of the limiting component slide smoothly, the limiting hole and limiting ring 9 on the support plate 1 3 are not deformed, the mounting plate 10, threaded ring 11 and mounting bolt 12 of the installation component are intact, the constraint ring 13 in the through hole of the connecting plate 1 is undamaged and the rubber pad 14 in the mounting groove is tightly fitted, then the connecting end of the precast concrete exterior wall panel is aligned with the mounting groove of the connecting plate 1, so that the edge of the exterior wall panel is in contact with the rubber pad 14 to complete the initial connection; then, according to the angle requirements of the construction design, the connecting plate 1 is slowly rotated with the rotating shaft 5 on the support plate 2 4 as the axis, and the rotating shaft 5 drives the externally fixed connection. Block 6 rotates synchronously to adjust the included angle between the two connecting plates 1 until the angle matches the design parameters and then stops. Then, pull up the positioning rod 8 inside the turntable 7 to align it with the corresponding angle limit hole on the support plate 3 and release it. The positioning rod 8 is inserted into the hole, and the limit ring 9 ensures that it fits tightly against the hole wall to lock the rotating shaft 5 and prevent the connecting plate 1 from shifting angle. Then, pass the mounting bolt 12 through the threaded ring 11 inside the mounting plate 10, align it with the preset mounting hole of the outer wall panel and tighten it to initially fix the connecting plate 1 and the outer wall panel. Then, rotate the positioning bolt 2, and with the assistance of the constraint ring 13, make it penetrate deeper into the outer wall panel to further enhance the tightness of the connection. Finally, the rubber pad 14 fills the splicing gap to ensure the sealing, forming a connection structure that meets the construction requirements.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
