Description

Technical Field

[0001] This invention belongs to the field of building envelope technology, specifically a high-efficiency construction envelope structure for prefabricated concrete buildings and its application method. Background Technology

[0002] Prefabricated concrete buildings are concrete structures assembled and connected with prefabricated components as the main load-bearing components. Prefabricated concrete buildings are one of the important directions for the development of building structures in my country.

[0003] When assembling prefabricated concrete buildings, an enclosure structure is required to improve the convenience and safety of construction. In the traditional prefabricated concrete structure enclosure installation project, scaffolding needs to be erected in advance, and the fixing of the scaffolding and the installation of the outer guardrails require drilling holes in the prefabricated walls and fixing them with bolts. The above method will damage the wall structure because it requires drilling holes in the wall. When the outer enclosure is removed, the wall also needs to be repaired. In addition, the traditional enclosure structure needs to be erected on a large area outside the entire prefabricated exterior wall panel, which is not only cumbersome to assemble and disassemble, but also costly. Summary of the Invention

The overlapping walking platform is connected to the top of the upper support plug-in assembly and the lower support plug-in assembly respectively. The retractable protective panel assembly is located on the side of the protective support upright that is away from the prefabricated concrete exterior wall panel. The retractable protective panel assembly is connected to the protective support upright through the lifting adjustment assembly.

The U-shaped limiting pin is inserted through the first limiting sleeve and the second limiting sleeve. The side pull ring is fixedly connected to one end of the top of the U-shaped limiting pin and matches the open-type limiting support sleeve.

[0011] Preferably, the overlapping walking platform consists of a support frame, several auxiliary support beams, a support mesh plate, a U-shaped sleeve, and a locking pin.

[0013] Preferably, the auxiliary limiting component consists of an L-shaped lifting column, a limiting rack, a second worm gear, an adjusting screw, and a movable support shaft seat.

The limiting rack is fixedly connected to the bottom end of the L-shaped lifting column and matches the second worm gear. The movable support shaft seat is fixedly connected to the top end of the second housing. The adjusting screw is inserted into the L-shaped lifting column and movably connected to the movable support shaft seat.

[0014] A method for using a high-efficiency construction enclosure structure for prefabricated concrete buildings, including the aforementioned high-efficiency construction enclosure structure for prefabricated concrete buildings, is as follows:

[0015] During the production of prefabricated concrete exterior wall panels, pre-reserved through holes are precisely drilled in the panels. Embedded sleeves are installed inside these holes. When installing the main enclosure later, the enclosure can be directly inserted into the embedded sleeves. The upper and lower support plug-in components support the protective support uprights. The overlapping walking platform is attached to the top of the upper and lower support plug-in components to facilitate worker movement. The lifting protective panel assembly is connected to the side of the protective support uprights via a lifting adjustment component. After the overall installation is completed, the lifting protective panel assembly is raised using the lifting adjustment component to achieve comprehensive safety protection.

[0016] When installing the upper and lower support plug-in components, the main support beam is inserted through the pre-embedded sleeve, and the internal threaded sleeve and support pad are fitted onto the internal threaded connector and locked, so that one side of the load-bearing support pad is in contact with the outer edge of the prefabricated concrete exterior wall panel. Therefore, the load-bearing support pad can provide load support for the main support beam, reduce the pressure of the main support beam on the pre-embedded sleeve, and improve the stability of the installation. The triangular limit baffle is used to limit the position of the protective support upright. Since multiple upper and lower support plug-in components are set, the stress uniformity after the main enclosure is installed can be improved.

[0017] The lifting baffle is slidably connected to the protective support plate via T-shaped limiting strips and T-shaped limiting grooves. Therefore, when adjusting the lifting baffle, the T-shaped limiting strips and T-shaped limiting grooves can be used to vertically limit the lifting baffle, preventing it from falling off and improving the stability of the connection. After the lifting baffle rises to the top, the rotating side baffle is rotated to the port where the protective support plate connects to the prefabricated concrete exterior wall panel, thus sealing the port and improving safety. After the rotating side baffle is closed, the side pull ring is moved out of the open-type limiting support sleeve, causing the U-shaped limiting pin to move down and engage with the overlapping walking platform. When the lifting baffle needs to be reset after use, it is buffered by a descending buffer assembly consisting of a limiting top plate, an I-shaped limiting pressure column, and a buffer spring. The I-shaped limiting pressure column moves up, and the buffer spring is compressed, thereby improving the buffering effect and preventing the lifting baffle from colliding with the protective support plate.

[0018] During installation of the interlocking walking platform, the U-shaped clamps are engaged with the upper and lower support connectors respectively, enabling quick installation and disassembly and improving operational convenience. Locking pins are used to secure the platform, enhancing its stability. The auxiliary support beams are installed inside the support frame to provide auxiliary support for the support mesh, improving safety. The pin holes allow for engagement and positioning of the U-shaped limit pins.

[0019] When adjusting the lifting and lowering of the protective plate assembly, the auxiliary limit component is unlocked. Turning the handwheel drives the worm gear, which in turn drives the first worm wheel. The first worm wheel then drives the main shaft, which in turn drives the first and second sheaves at both ends. These sheaves tighten the traction steel cables at both ends, causing the lifting and lowering assembly to rise. Because both ends are simultaneously traction-driven, the stability of the lifting and lowering is improved, and the resistance to movement is reduced. After the lifting and lowering adjustment is completed, the first worm wheel and worm gear achieve self-locking. Simultaneously, turning the adjusting screw causes the L-shaped lifting column and the limit rack to descend, causing the limit rack to engage with the second worm wheel, forming a limit. These two sets of limit structures effectively prevent the lifting and lowering assembly from descending on its own, improving safety during use.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) In operation, by setting up an enclosure body consisting of several upper support plug-in components, several lower support plug-in components, protective support uprights, several overlapping walking platforms, lifting protective plate components and lifting adjustment components, the enclosure body can be installed through pre-embedded sleeves, thereby improving the convenience of installation and disassembly, and effectively improving the stability of the installation, avoiding loosening and falling off, and thus improving the safety of use. It is movable during use and can be quickly disassembled and assembled according to the change of the use position, so there is no need for large-area construction, effectively reducing costs. Through the lifting protective plate components and lifting adjustment components, it can be retracted when not in use, effectively reducing the volume of the enclosure body, thus facilitating movement and transportation.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1, by Figure 1 and Figure 2The present invention discloses an efficient construction enclosure structure for prefabricated concrete buildings and its usage method, comprising an enclosure body 1 connected to one side of a prefabricated concrete exterior wall panel 2. The prefabricated concrete exterior wall panel 2 has several reserved through holes matching the enclosure body 1. Pre-embedded sleeves 3 are fixedly installed inside the reserved through holes. The enclosure body 1 is inserted through the pre-embedded sleeves 3. The enclosure body 1 consists of several upper support insertion components 4, several lower support insertion components 5, protective support uprights 6, several overlapping walking platforms 7, lifting protective plate components 8, and lifting... The adjustment component 9 consists of an upper support plug-in component 4 and a lower support plug-in component 5, one end of which is inserted into the pre-embedded sleeve 3. The protective support upright plate 6 is sleeved on the end of the upper support plug-in component 4 and the lower support plug-in component 5 away from the pre-embedded sleeve 3. The overlapping walking platform 7 is connected to the top of the upper support plug-in component 4 and the lower support plug-in component 5 respectively. The lifting protective plate component 8 is located on the side of the protective support upright plate 6 away from the prefabricated concrete exterior wall panel 2. The lifting protective plate component 8 is connected to the protective support upright plate 6 through the lifting adjustment component 9.

[0037] During the production of prefabricated concrete exterior wall panels 2, pre-reserved through holes are precisely drilled on the prefabricated concrete exterior wall panels 2, and pre-embedded sleeves 3 are installed inside the pre-reserved through holes. When installing the main enclosure 1 later, the main enclosure 1 can be directly inserted into the pre-embedded sleeves 3. The upper support plug-in component 4 and the lower support plug-in component 5 support the protective support upright plate 6. The overlapping walking platform 7 overlaps the top of the upper support plug-in component 4 and the lower support plug-in component 5 to facilitate the movement of workers. The lifting protective plate component 8 is connected to the side of the protective support upright plate 6 through the lifting adjustment component 9. After the overall installation is completed, the lifting protective plate component 8 is raised by the lifting adjustment component 9 to achieve comprehensive safety protection.

[0038] Example 2, by Figures 1 to 3As shown, both the upper support plug-in assembly 4 and the lower support plug-in assembly 5 are composed of a support main beam 10, an internal threaded sleeve 11, a support pad 12, a load-bearing support pad 13, and an external threaded sleeve 14. One end of the support main beam 10 is inserted into the pre-embedded sleeve 3, and one end of the support main beam 10 is fixedly provided with an internal threaded connector 15 that matches the internal threaded sleeve 11. The other end of the support main beam 10 is fixedly provided with an external threaded head 16 that matches the external threaded sleeve 14. The internal threaded sleeve 11 and the support pad 12 are located in an assembled... The inner sidewall of the concrete exterior wall panel 2 is fitted with the internal threaded connector 15, the external threaded sleeve 14 is fitted with the external threaded head 16 and is attached to one side of the protective support plate 6, the load-bearing support pad 13 is fixedly connected to the middle position of the bottom end of the support beam 10 and is attached to the outer side of the prefabricated concrete exterior wall panel 2, the load-bearing support pad 13 is fixedly provided with a wear-resistant buffer pad 17 on the side of the prefabricated concrete exterior wall panel 2, and a triangular limiting baffle 18 is fixedly provided at the bottom end of the support beam 10 near the protective support plate 6.

[0039] When installing the upper support plug-in assembly 4 and the lower support plug-in assembly 5, the main support beam 10 is inserted through the pre-embedded sleeve 3, and the internal threaded sleeve 11 and the support pad 12 are fitted onto the internal threaded connector 15 and locked, so that one side of the load-bearing support pad 13 is in contact with the outer side of the prefabricated concrete exterior wall panel 2. Therefore, the load-bearing support pad 13 can provide load support for the main support beam 10, reduce the pressure of the main support beam 10 on the pre-embedded sleeve 3, and improve the stability of the installation. The protective support upright plate 6 is limited by the triangular limiting baffle 18. Since multiple upper support plug-in assemblies 4 and multiple lower support plug-in assemblies 5 are set, the stress uniformity of the enclosure body 1 after installation can be improved.

[0040] Example 3, by Figures 2 to 8The lifting protective plate assembly 8 consists of a lifting baffle 19, a lowering buffer assembly 20, several rotating side baffles 21, and a limiting pin assembly 22. A T-shaped limiting strip 23 is fixedly installed on the side of the lifting baffle 19 near the protective support upright 6. Several T-shaped limiting grooves 24 matching the T-shaped limiting strips 23 are opened on the side of the protective support upright 6 near the lifting baffle 19. The lowering buffer assembly 20 is fixedly connected to the top of the lifting baffle 19. The rotating side baffles 21 are movably connected to both ends of the lifting baffle 19. The limiting pin assembly 22 is fixedly connected to one side of the rotating side baffle 21. The lowering buffer assembly 20 consists of a limiting top plate 25, an I-shaped limiting pressure column 26, and a buffer spring 27. The limiting top plate 25 is fixedly connected to... At the top of the lifting baffle 19, an I-shaped limiting pressure column 26 is inserted through one side of the top of the limiting top plate 25. A buffer spring 27 is located at the bottom of the limiting top plate 25 and is sleeved on the I-shaped limiting pressure column 26. A rubber pad 28 is fixedly installed at the bottom of the I-shaped limiting pressure column 26. The limiting pin assembly 22 consists of a first limiting sleeve 29, a second limiting sleeve 30, a U-shaped limiting pin 31, a side pull ring 32, and an open-type limiting support sleeve 33. The first limiting sleeve 29, the second limiting sleeve 30, and the open-type limiting support sleeve 33 are all fixedly connected to one side of the rotating side baffle 21. The U-shaped limiting pin 31 is inserted through the first limiting sleeve 29 and the second limiting sleeve 30. The side pull ring 32 is fixedly connected to one end of the top of the U-shaped limiting pin 31 and matches the open-type limiting support sleeve 33.

[0041] The lifting baffle 19 is slidably connected to the protective support plate 6 via a T-shaped limiting strip 23 and a T-shaped limiting groove 24. Therefore, when adjusting the lifting baffle 19, the T-shaped limiting strip 23 and the T-shaped limiting groove 24 can vertically limit the lifting baffle 19, preventing it from falling off and improving the stability of the connection. After the lifting baffle 19 rises to its highest point, the rotating side baffle 21 is rotated to the port where the protective support plate 6 connects to the prefabricated concrete exterior wall panel 2, thus sealing the port. To improve safety, after the rotating side baffle 21 is closed, the side pull ring 32 is moved out of the open-type limiting support sleeve 33, so that the U-shaped limiting pin 31 moves down and engages with the overlapping walking platform 7. When the lifting baffle 19 needs to be reset after use, it is buffered by the descending buffer assembly 20 composed of the limiting top plate 25, the I-shaped limiting pressure column 26 and the buffer spring 27. The I-shaped limiting pressure column 26 moves up and the buffer spring 27 is compressed, thereby improving the buffering effect and preventing the lifting baffle 19 from colliding with the protective support plate 6.

[0042] Example 4, by Figure 2 and Figure 10The overlapping walking platform 7 is composed of a support frame 34, several auxiliary support beams 35, support mesh plates 36, U-shaped sleeves 37 and locking pins 38. The auxiliary support beams 35 are fixedly connected to the inside of the support frame 34, the support mesh plates 36 are fixedly connected to the top of the support frame 34 and the auxiliary support beams 35, the U-shaped sleeves 37 are fixedly connected to both ends of the bottom of the support frame 34, and the locking pins 38 are inserted into the support frame 34 and the U-shaped sleeves 37. Both ends of the support frame 34 are provided with pin holes 39 that match the U-shaped limiting pins 31.

[0043] When installing the overlapping walking platform 7, the U-shaped clamps 37 are engaged with the upper support plug-in assembly 4 and the lower support plug-in assembly 5 respectively, thereby enabling quick installation and disassembly, improving the convenience of operation. The locking pins 38 are used to lock the platform, improving the stability of the overlapping walking platform 7 installation. The auxiliary support beam 35 is installed inside the support frame 34 to provide auxiliary support for the support mesh plate 36, improving the safety of use. The pin hole 39 can be used to engage and limit the U-shaped limit pin 31.

[0044] Example 5, by Figure 2 and Figure 9 The lifting adjustment assembly 9 is composed of a first housing 40, a second housing 41, a first worm gear 42, a worm 43, a handwheel 44, a main shaft 45, a first spool 46, a second spool 47, and an auxiliary limiting assembly 48. The first housing 40 and the second housing 41 are respectively fixedly connected to both ends of one side of the protective support plate 6. The main shaft 45 passes through the first housing 40 and the second housing 41. The first worm gear 42 is located inside the first housing 40 and is sleeved on the main shaft 45. The worm 43 passes through the first housing 40 and meshes with the first worm gear 42. The handwheel 44 is fixedly connected to the top end of the worm 43. The first spool 46 and the second spool 47 are respectively fixedly connected to both ends of the main shaft 45. It is connected to the lifting protective plate assembly 8 via the traction steel rope 49. The auxiliary limiting assembly 48 is connected to the top of the second housing 41. The auxiliary limiting assembly 48 consists of an L-shaped lifting column 50, a limiting rack 51, a second worm gear 52, an adjusting screw 53, and a movable support shaft seat 54. The second worm gear 52 is located inside the second housing 41 and is sleeved on the main shaft 45. The L-shaped lifting column 50 is inserted into the second housing 41. The limiting rack 51 is fixedly connected to the bottom end of the L-shaped lifting column 50 and matches the second worm gear 52. The movable support shaft seat 54 is fixedly connected to the top of the second housing 41. The adjusting screw 53 is inserted into the L-shaped lifting column 50 and is movably connected to the movable support shaft seat 54.

[0045] When adjusting the lifting and lowering of the lifting protective plate assembly 8, the auxiliary limiting component 48 is unlocked, and the handwheel 44 is rotated. The handwheel 44 drives the worm gear 43 to rotate, which in turn drives the first worm wheel 42 to rotate. The first worm wheel 42 drives the main shaft 45 to rotate, which in turn drives the first pulley 46 and the second pulley 47 at both ends to rotate. The first pulley 46 and the second pulley 47 tighten the traction steel ropes 49 at both ends, thereby driving the lifting protective plate assembly 8 to rise. Since both ends are pulled simultaneously, the stability of the lifting and lowering is improved and the resistance to movement is reduced. After the lifting and lowering adjustment is completed, the first worm wheel 42 and the worm gear 43 can achieve self-locking. At the same time, the adjusting screw 53 is rotated, which drives the L-shaped lifting column 50 and the limiting rack 51 to descend, so that the limiting rack 51 engages with the second worm wheel 52 to form a limit. Through the two sets of limiting structures, the lifting protective plate assembly 8 can be effectively prevented from descending on its own, thus improving the safety of use.

[0046] In operation, the enclosure structure, consisting of several upper support plug-in components, several lower support plug-in components, protective support uprights, several overlapping walking platforms, lifting protective plate components, and lifting adjustment components, can be installed using pre-embedded sleeves. This improves the convenience of installation and disassembly, effectively enhances the stability of the installation, prevents loosening and detachment, and thus improves safety. The enclosure is also movable during use, allowing for quick assembly and disassembly based on changes in location, eliminating the need for large-scale construction and effectively reducing costs. Furthermore, the lifting protective plate components and lifting adjustment components allow for retraction when not in use, effectively reducing the volume of the enclosure structure and facilitating movement and transportation.

6. A method for using a high-efficiency construction enclosure structure for prefabricated concrete buildings, characterized in that: The high-efficiency construction enclosure structure for prefabricated concrete buildings as described in claim 1 is specifically operated as follows: When producing prefabricated concrete exterior wall panels (2), pre-reserved through holes are precisely opened on the prefabricated concrete exterior wall panels (2), and pre-embedded sleeves (3) are installed inside the pre-reserved through holes. When installing the enclosure body (1) later, the enclosure body (1) can be directly inserted into the pre-embedded sleeve (3). The upper support plug-in assembly (4) and the lower support plug-in assembly (5) support the protective support upright plate (6). The overlapping walking platform (7) overlaps on the top of the upper support plug-in assembly (4) and the lower support plug-in assembly (5) so that workers can walk. The lifting protective plate assembly (8) is connected to the side of the protective support upright plate (6) through the lifting adjustment assembly (9). After the overall installation is completed, the lifting protective plate assembly (8) is raised through the lifting adjustment assembly (9) to achieve comprehensive safety protection. When installing the upper support plug-in assembly (4) and the lower support plug-in assembly (5), the main support beam (10) is inserted through the pre-embedded sleeve (3), and the internal threaded sleeve (11) and the support pad (12) are fitted onto the internal threaded connector (15) and locked, so that one side of the load-bearing support pad (13) is in contact with the outer side of the prefabricated concrete exterior wall panel (2). Therefore, the load-bearing support pad (13) can provide load support for the main support beam (10), reduce the pressure of the main support beam (10) on the pre-embedded sleeve (3), and improve the stability of the installation. The protective support upright plate (6) is limited by the triangular limit baffle (18). Since multiple upper support plug-in assemblies (4) and multiple lower support plug-in assemblies (5) are set, the uniformity of the load after the main enclosure (1) is installed can be improved. The lifting baffle (19) is slidably connected to the protective support plate (6) through the T-shaped limiting strip (23) and the T-shaped limiting groove (24). Therefore, when the lifting baffle (19) is adjusted for lifting, the vertical limiting of the lifting baffle (19) can be achieved through the T-shaped limiting strip (23) and the T-shaped limiting groove (24), so as to prevent the lifting baffle (19) from falling off and improve the stability of the connection. After the lifting baffle (19) rises to the top, the rotating side baffle (21) is rotated to the port where the protective support plate (6) is connected to the prefabricated concrete exterior wall panel (2), thereby sealing the port. To improve safety, after the rotating side baffle (21) is closed, the side pull ring (32) is moved out from the open-type limiting support sleeve (33), so that the U-shaped limiting pin (31) moves down and engages with the overlapping walking platform (7). When the lifting baffle (19) needs to be reset after use, it is buffered by the descending buffer assembly (20) composed of the limiting top plate (25), the I-shaped limiting pressure column (26) and the buffer spring (27). The I-shaped limiting pressure column (26) moves up and the buffer spring (27) is compressed, thereby improving the buffering effect and preventing the lifting baffle (19) from colliding with the protective support plate (6). When installing the overlapping walking platform (7), the U-shaped sleeve (37) is engaged with the upper support plug-in component (4) and the lower support plug-in component (5) respectively, so as to achieve quick installation and disassembly, improve the convenience of operation, and lock it by locking pin (38) to improve the stability of the overlapping walking platform (7) installation. The auxiliary support beam (35) is installed inside the support frame (34) to provide auxiliary support for the support mesh plate (36) and improve the safety of use. The pin hole (39) can realize the engagement and limiting of the U-shaped limit pin (31). When adjusting the lifting protective plate assembly (8), the auxiliary limit assembly (48) is unlocked, and the handwheel (44) is turned. The handwheel (44) drives the worm gear (43) to rotate, the worm gear (43) drives the first worm wheel (42) to rotate, and the first worm wheel (42) drives the main shaft (45) to rotate. Thus, the main shaft (45) synchronously drives the first pulley (46) and the second pulley (47) at both ends to rotate. The first pulley (46) and the second pulley (47) tighten the traction steel ropes (49) at both ends, thereby driving the lifting protective plate assembly (8) to rotate. The protective plate assembly (8) rises. Since both ends are pulled simultaneously, the stability of the lifting and lowering is improved and the motion resistance is reduced. After the lifting and lowering adjustment is completed, the first worm gear (42) and worm (43) can achieve self-locking. At the same time, the adjusting screw (53) is rotated, and the L-shaped lifting column (50) and the limiting rack (51) are driven to fall through the adjusting screw (53), so that the limiting rack (51) engages with the second worm gear (52) to form a limit. Through the two sets of limiting structures, the lifting protective plate assembly (8) can be effectively prevented from falling down by itself, thus improving the safety of use.
