Description

Technical Field

[0001] The present invention relates to the technical field of exterior wall assembly, in particular to an assembled exterior wall structure. Background Art

[0002] With economic and social development, lightweight steel structures are becoming increasingly common. With the nation's advocacy for energy-saving and low-carbon architecture, lightweight steel-structured housing has been vigorously developed as a green, environmentally friendly, and energy-saving housing system. Lightweight steel-structured housing offers advantages such as short construction periods, low weight, and excellent seismic resistance, sound insulation, and thermal insulation. Lightweight steel-structured housing has seen rapid development, with current lightweight steel-structured prefabricated housing primarily consisting of walls, floor slabs, roofs, and support structures.

[0003] When assembling prefabricated exterior wall structures, it is generally necessary to lay a good foundation first, and pre-embedded steel bars are pre-installed at fixed positions on the foundation surface for plugging and fixing with the exterior wall. Then the eyebolts are screwed into the embedded sleeves above the wall panel, and the hanging hook lifts the upper end of the wall panel through the crane, so that the entire wall panel is lifted to the set position. There is a socket at the bottom of the wall panel. The worker pushes the wall panel so that the position of the socket corresponds to the position of the top of the steel bar. The crane gradually lowers the exterior wall to complete the plug-in fixation. After that, the wall panel is supported by the diagonal rod, and the verticality and position of the wall panel are measured for accuracy. After fine-tuning is completed, the lifting can be released, and the eyebolt above can be unscrewed and recovered to release the fixation with the wall panel.

[0004] Existing operations require frequent disassembly and assembly of eyebolts. Due to the high top surface of the cavity, workers need to climb to the top of the cavity using a ladder and use tools to continuously turn the bolts for disassembly and assembly. The frequent construction process wastes a lot of manpower and also reduces assembly efficiency. Existing eyebolts are difficult to fix to the top of the exterior wall through pre-installation and automatically detach from the wall after the hoisting is completed, resulting in an inconvenient and inefficient use process. To this end, we propose an assembled exterior wall structure. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-Figure 5 , an assembled exterior wall structure shown in the figure includes a wall 1, a hoisting mechanism 3, a control mechanism 5 and a trigger mechanism 7. A plurality of positioning holes 2 are provided on the bottom surface of the wall 1. The hoisting mechanism 3 includes a hook 4 installed on the wall 1. The hoisting mechanism 3 is used to lift the hook 4 to assist in hoisting the wall 1 to a suitable position for installation. The control mechanism 5 includes a control rod 6 installed in the positioning hole 2. The side of the control rod 6 is slidably connected to the inner wall of the positioning hole 2 in the vertical direction. The control mechanism 5 is used to fix the hoisting mechanism 3 on the wall 1 and insert the embedded steel bar 39 into the positioning hole 2. When the positioning hole 2 is reached, the control rod 6 is pushed upward, thereby gradually accumulating force for the subsequent release of the connection between the lifting mechanism 3 and the wall 1. The trigger mechanism 7 includes a support block 8 installed on the wall 1. The trigger mechanism 7 is used to trigger the release of the force of the control mechanism 5 after the inclined rod and the support block 8 are tightly supported, so that the lifting mechanism 3 is completely separated from the wall 1, completing the purpose of automatic separation. The lifting mechanism 3 also includes a plurality of device rods 9 plugged into the positioning hole 2, and the top of the device rod 9 is fixedly connected to the top plate 10. There are multiple groups of hooks 4, and they are all fixedly connected to the top surface of the top plate 10.

[0033] See also Figures 1-8The control mechanism 5 shown in the figure also includes multiple groups of plug-in blocks 11 installed on the device rod 9. A charging chamber 12 is provided at the bottom end of the device rod 9. The control rod 6 is slidably connected to the inner wall of the charging chamber 12 in the vertical direction. Multiple groups of sliding grooves 13 are provided on the device rod 9. The plug-in blocks 11 are slidably connected to the sliding grooves 13 in the horizontal direction. A plug-in groove 14 that can be plugged into the plug-in blocks 11 is provided on the wall 1. Multiple groups of fixed steel bars 38 are fixedly connected in the wall 1. The top surface of the plug-in groove 14 is flush with the bottom surface of the fixed steel bar 38. A force storage member 15 is provided in the device rod 9 for storing force when the control rod 6 squeezes the fluid in the charging chamber 12.

[0034] In this embodiment, during production, it is necessary to open multiple groups of positioning holes 2 in the wall 1, and open the upper ends of several groups of positioning holes 2 (two groups in the figure), pass through the wall 1, and drill multiple groups of plug-in grooves 14 evenly on the side of the wall 1. At the same time, the upper end surface of the plug-in groove 14 is flush with the lower section of the original fixed steel bar 38 in the wall 1, so that after the plug-in block 11 is inserted into the plug-in groove 14, the upper side of the plug-in block 11 conflicts with the bottom surface of the fixed steel bar 38, so that the force applied during the lifting process is applied to the fixed steel bar 38, and the lifting process is more stable. The device rod 9 is inserted into the wall 1 as a whole until the plug-in block 11 and the plug-in groove 14 are fully plugged in to achieve the installation of the hook 4.

[0035] It is worth noting that: during hoisting, the hook 4 is fixed to the hanging rope of the crane, and the wall 1 is hoisted to the upper end of the embedded steel bar 39, so that the positioning hole 2 is vertically aligned with the embedded steel bar 39, and then the wall 1 is gradually driven downward for installation. When the embedded steel bar 39 is inserted into the positioning hole 2, the control rod 6 is pushed upward, thereby gradually triggering the force storage member 15 to operate for the subsequent release of the connection state between the hoisting mechanism 3 and the wall 1 to store force. The trigger mechanism 7 is triggered to release the force of the control mechanism 5 after the inclined rod and the support block 8 are tightly supported, so that the hoisting mechanism 3 is completely separated from the wall 1, completing the purpose of automatic separation. The device is simple in result and easy to produce. The hoisting mechanism 3 can be recycled when producing the wall 1. It is driven by fluid and does not require a motor. It has low cost and is simple and quick to operate. The hook 4 is automatically separated when the wall 1 is hoisted and fixed, which greatly improves the installation efficiency of the prefabricated exterior wall and is convenient to use.

[0036] Example 2

[0037] See also Figure 7-12Example 2 is described. This example further explains Example 1. The force storage member 15 shown in the figure includes a fixing ring 16 fixedly mounted on the device rod 9. A force storage chamber 17 is provided on the device rod 9. A connecting pipe 18 for connecting the force storage chamber 17 with the pressure charging chamber 12 is provided in the device rod 9. The fixing ring 16 is fixedly mounted in the force storage chamber 17. A first spring 19 is fixedly connected to the bottom surface of the fixing ring 16. A rubber ball 20 for sealing the upper opening of the connecting pipe 18 is fixedly connected to the lower end of the first spring 19. A control member 21 for controlling the sealing state of the upper end of the connecting pipe 18 is provided on the device rod 9. A driving member 22 for driving the plug-in block 11 to be ejected when the trigger mechanism 7 is in operation is provided in the force storage chamber 17. The control member 21 includes a rotating tube 28 rotatably connected to the outer wall of the device rod 9. A lifting rod 29 is slidably connected to the device rod 9 in the vertical direction. A control block 30 is fixedly connected to the side of the lifting rod 29. The inner wall of the rotating tube 28 is provided with a threaded groove 31 slidably connected to the control block 30.

[0038] See also Figure 7-12 The driving member 22 shown in the figure includes a fixed tube 23 fixedly installed at the upper end of the storage chamber 17. The outer wall of the fixed tube 23 is slidably connected to a lifting plate 24 in the vertical direction. The top surface of the lifting plate 24 is fixedly connected to a second spring 25 fixedly connected to the top surface of the storage chamber 17. The side of the plug-in block 11 is fixedly connected to a driving block 26. The driving block 26 is slidably connected to the sliding groove 13 in the horizontal direction. A delivery pipe 27 is provided in the device rod 9 for filling the flow in the fixed tube 23 to one side of the driving block 26, thereby pushing the driving block 26 to drive the plug-in block 11 to slide together in the sliding groove 13. The trigger mechanism 7 is used to control the communication state between the fixed tube 23 and the delivery pipe 27.

[0039] In this embodiment, when the embedded steel bar 39 is inserted into the positioning hole 2, the control rod 6 will be gradually lifted, and the control rod 6 will slide into the charging chamber 12, so that the fluid pressure in the charging chamber 12 increases, and the fluid lifts the rubber ball 20 through the connecting pipe 18 and outputs it to the storage chamber 17. At this time, the trigger mechanism 7 closes the connection between the delivery pipe 27 and the fixed pipe 23, and the fluid in the storage chamber 17 cannot flow out. The pressure gradually increases, thereby causing the lifting plate 24 to move up and compress the second spring 25. When the wall 1 is completed, the position of the control rod 6 is fixed. At this time, the pressure in the storage chamber 17 is much greater than the pressure in the charging chamber 12, so that the rubber ball 20 is pushed downward, thereby sealing the connecting pipe 18 and preventing the backflow of the fluid.

[0040] Afterwards, when the inclined rod and the support block 8 are tightly supported and fixed, the trigger mechanism 7 connects the fixed pipe 23 with the delivery pipe 27, and the fluid in the storage chamber 17 is output to the delivery pipe 27 through the fixed pipe 23. The pressure instantly pushes the driving block 26 and the plug-in block 11 to slide in the sliding groove 13, and the plug-in block 11 is disconnected from the plug-in groove 14 to achieve the purpose of separation. After that, the crane is pulled up to drive the top plate 10 and the device rod 9 to move up as a whole and slide out of the wall 1 to achieve separation. During this process, the control rod 6 is no longer pushed by the embedded steel bars 39, but Due to the resistance of the rubber ball 20, the backflow of the fluid in the storage chamber 17 is effectively avoided, so that during the upward movement, the fluid pressure in the storage chamber 17 stably pushes the plug-in block 11 to slide into the sliding groove 13, avoiding the top end of the plug-in block 11 from extending and causing wear on the wall 1. When the device rod 9 needs to be reused, it is only necessary to rotate the rotating tube 28 so that the threaded groove 31 pushes the control block 30 to drive the lifting rod 29 to move upward, lift the rubber ball 20, and pull out the control rod 6 to allow the liquid in the delivery pipe 27 to flow back into the pressure charging chamber 12, completing the reset operation.

[0041] Example 3

[0042] See also Figures 1-10 Example 3 is described. This example further illustrates Example 1. The trigger mechanism 7 shown in the figure also includes a fixed plate 32 mounted on the wall 1. The fixed plate 32 is threadedly connected to a nut 33 threadedly connected to the side of the wall 1. The number of fixed plates 32 is the same as the number of device rods 9. The support block 8 passes through the fixed plate 32 and is connected to the fixed plate 32 in a horizontal sliding direction. A trigger member 34 is provided in the device rod 9 for controlling the communication state between the fixed pipe 23 and the delivery pipe 27 when the support block 8 slides.

[0043] See also Figure 7-12 The trigger member 34 shown in the figure includes a trigger block 35 installed in the device rod 9. A guide groove 36 is provided in the device rod 9 and is horizontally slidably connected to the trigger block 35. A through hole 37 is provided on the trigger block 35 for connecting the upper end of the fixed pipe 23 and the lower end of the delivery pipe 27. The trigger block 35 is made of a magnet and the support block 8 is made of a magnetic metal material.

[0044] In this embodiment, when installing the device rod 9, since the trigger block 35 is made of magnetic material, when it slides to the position of the support block 8, it will be attracted by the support block 8, thereby sliding out of the guide groove 36, so that the position of the through hole 37 deviates from the upper end of the fixed tube 23, thereby achieving blocking. When the wall 1 is hoisted and connected with the embedded steel bar 39, in order to facilitate the insertion of the positioning hole 2 and the embedded steel bar 39, the aperture of the positioning hole 2 is larger than the diameter of the embedded steel bar 39. Therefore, the fixing strength of the embedded steel bar 39 to the wall 1 is limited at this time, and it is necessary to connect the inclined rod with the embedded steel bar 39. The support block 8 interferes so that both sides of the wall 1 are stably supported, which is convenient for subsequent fixing operations and prevents the wall 1 from becoming unstable after the hook 4 is detached. Therefore, the hook 4 must be detached only after the diagonal rod support is completed. When the diagonal rod support pushes the support block 8, the support block 8 slides on the fixed plate 32, thereby pushing the trigger block 35 into the guide groove 36, so that the through hole 37 is connected with the fixed tube 23 and the delivery tube 27, and the fluid in the storage chamber 17 flows out to the delivery tube 27 to realize the detachment between the device rod 9 and the wall 1.
