Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and more particularly to a reinforcing method and device for an ultrahigh external wall. BACKGROUND

[0002] The enclosure system is an important part of prefabricated buildings, and the system performance directly affects the overall performance of the building. The main components of traditional steel structure buildings have basically realized factory prefabrication and on-site installation, but the building enclosure system still uses traditional masonry walls. Masonry walls require on-site completion of multiple wet work procedures such as masonry and plastering, which has high time and labor costs. In particular, for this project, in addition to the long construction period and high labor costs of masonry external walls, the height of the warehouse roof is more than 11m. In order to ensure the smooth construction of the steel structure roof, the external scaffolding of each warehouse has been removed, resulting in an increase in the cost of measures if the masonry external wall is continued to be used. If the masonry external wall is changed to an embedded ALC plate, the construction period, labor cost, and measure cost will be optimized. However, the height of the external wall of this project is 1800mm, which exceeds the specified "external wall height not exceeding 1200mm" in the diagram set 13J104 "autoclaved aerated concrete block, plate structure". In addition, the duration and frequency of the wind season in the area where the project is located is long, and the wind resistance needs to be enhanced to ensure the wind resistance.

[0003]

[0004] In addition, during the installation of the ALC plate, the ALC plate body is heavy and needs to be manually transported to a specific installation position. When placed, the worker is at the edge of the wall without a fence, which is dangerous and inconvenient for installation. During welding, the worker needs to manually correct the position of the ALC plate, which will cause a large deviation of the welded ALC plate position, resulting in defects in the installed external wall and affecting the wind resistance effect of the external wall.

[0005] Based on this, the present application designs a reinforcing method and device for an ultrahigh external wall to solve the above problems. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Step 1: The keel column 1, with a height of 1700mm, is welded to the roof steel structure column cap, and the angle steel is fully welded to the three sides of the welding area to reinforce the diagonal cut steel 7.

[0041] Step 2: Install the reinforcing column 3 at the middle of each span, and weld a square steel 20 with a height of 2300mm from the keel capping 2. The square steel 20 is reinforced to the web of the roof steel structure beam by welding angle brackets.

[0042] Step 3: The keel capping 2, with a length of 5000mm, is fully welded to the keel column 1 and the reinforcing column 3;

[0043] Step 4: Use 5000*200*600 ALC plate 6 horizontally at the external wall. When welding ALC plate 6 to keel column 1, two hook bolts 4 need to be driven in and welded to column angle steel 5.

[0044] Step 5: Combining the installation methods of Steps 1 to 4, use the reinforcement device to vertically stack and install ALC panels 6 on the external wall between the keel column 1 and the reinforcing column 3, until the external wall is fully stacked and the ALC panels 6 are installed. Then, fix the keel capping 2 to complete the installation.

[0045] A method for reinforcing an ultra-high external wall, wherein the steel grade of the keel column 1 and the reinforcing column 3 is upgraded to Q335B with a cross-sectional size of 200*300, and the wall thickness of the square steel is increased to 10mm; a reinforcing node is added between the reinforcing column 3 and the steel structure roof beam; the keel capping 2 is made of Q335B with a cross-sectional size of 200*100*10.

[0046] Please see Figures 1-11 An apparatus for reinforcing the aforementioned ultra-high external wall is provided, comprising a reinforcing device. The reinforcing device includes a hoisting mechanism 8 for hoisting the ALC plate 6 and a transport mechanism 10 for carrying the ALC plate 6 and assisting in its fixed installation. The transport mechanism 10 is integrally fixedly mounted on a base 13 located below. The transport mechanism 10 is characterized by having an internal cavity for placing the ALC plate 6, with an opening at the top. Both shorter sides of the cavity are provided with external wall fixing grooves 19 for clamping and fixing the ALC plate 6. A gear meshing assembly 101 is provided within the cavity, with one part of the gear meshing assembly 101 located inside the cavity and the other part extending to the outside of the cavity through an external through-hole in the transport mechanism 10. The gear meshing assembly 101 is positioned... A gear lever 102 is provided inside the cavity, and a rotating fixed rod 103 is provided on the other part extending to the outside of the transport mechanism 10. When the gear lever 102 is rotated under force, it drives the rotating fixed rod 103 to rotate synchronously through the gear meshing group 101. A movable base plate 17 is provided at the lower part of the base 13. A groove is provided at the upper part of the movable base plate 17. A spring 14 is fixed in the groove. When the ALC plate 6 is removed from the transport mechanism 10, the total mass on the base 13 is reduced, and the base 13 rises under the action of the spring 14. A moving key 16 is provided at the lower part of the movable base plate 17, and a moving groove 15 is provided at the upper part of the vehicle body below. The moving key 16 slides in the moving groove 15, and the movable base plate 17 and the upper base 13 slide together accordingly.

[0047] During operation, the two sides of the external wall are placed in the external wall fixing slot 19. One end of the gear swing rod 102 is installed on the gear shaft, and the other end is obliquely downward above the ALC plate inside the carrying mechanism 10. One end of the rotating fixing rod 103 is installed on the other gear shaft of the gear meshing group 101, and the other end of the supporting block is obliquely downward outside the carrying mechanism 10. When the ALC plate 6 is clamped out, the ALC plate 6 pushes the gear swing rod 102 upward, and the gear swing rod 102 rotates. Through the gear meshing group 101, the rotating fixing rod 103 rotates simultaneously. When the external wall is removed, the spring 14 at the bottom will deform, pushing the base 13 upward. When subjected to the action of the wedge block, the movable key 16 at the bottom of the movable base plate 17 will slide in the movable groove 15. The movable base plate 17 and the carrying mechanism 10 on the movable base plate 17 move together. This structure installs two rods through two gear meshing groups 101 with a large difference in the number of teeth, and links them with the loading and unloading process of ALC plate 6. This allows the rotating fixed rod 103 to be perpendicular to the outer wall of the carrying mechanism 10 when installing ALC plate 6. Through the spring 14 and the wedge block, the change in mass of ALC plate 6 is converted into the power for the carrying mechanism 10 to move forward, so that the rotating fixed rod support block can abut against the ALC plate 6 being installed.

[0048] As a further embodiment of the present invention, the hoisting mechanism 8 is located above the transport mechanism 10. The outermost part of the hoisting mechanism 8 includes a hoisting mechanism housing 81. A transverse spiral push rod 82 is rotatably mounted below the hoisting mechanism housing 81. The transverse spiral push rod 82 passes through the interior of a transverse moving slide 89. The transverse moving slide 89 is slidably engaged within the hoisting mechanism housing 81. A clamping mechanism 83 is fixedly disposed below the transverse moving slide 89. A pressurizing device is fixedly installed in the upper cavity of the clamping mechanism 83. Pump 84; the clamping mechanism 83 has a pressurizing chamber 87 in the middle, and a connecting plate that slides up and down in a sealed manner with changes in air pressure at the bottom of the pressurizing chamber 87. Multiple electric clamping devices 88 are fixedly connected below the connecting plate. The pressurizing pump 84 inputs gas into the pressurizing chamber 87 through the pressurizing pipe 85 to increase the air pressure in the pressurizing chamber 87 and cause the electric clamping devices 88 to move downward. An electrically controlled pressure relief valve 80 is provided on one side of the pressurizing chamber 87, and multiple return springs 86 for resetting the connecting plate are fixedly installed inside the pressurizing chamber 87.

[0049] During operation, the hoisting mechanism housing 81 in the hoisting mechanism 8 reaches the appropriate position under the action of the transverse spiral push rod 82 and spiral push rod 9. The transverse moving slide 89 makes a fine adjustment to the pressure pump 84 inside the clamping mechanism 83 below. The pressure inside the pressure chamber 87 is increased through the pressure pipe 85. The electric clamping device 88 moves downward and contacts the external wall to clamp. The pressure relief valve 80 releases pressure, and the pressure inside the pressure chamber 87 decreases. Under the action of the return spring 86, the electric clamping device 88 grabs the external wall and moves it upward.

[0050] As a further embodiment of the present invention, a clamping mechanism 104 is fixed above the gear lever 102. When the gear lever 102 rotates to the position of the clamping mechanism 104, the clamping mechanism 104 fixes the gear lever 102. The gear lever 102 drives the rotating fixing rod 103 to rotate to a position perpendicular to the outer wall of the transport mechanism 10 through the gear meshing group 101. The rotating fixing rod 103 is L-shaped and has a circular support block at the bottom. The lower support block of the rotating fixing rod 103 abuts against the ALC plate 6 of the electric clamping device 88 placed into the outer wall fixing groove 19 from the side.

[0051] During operation, when the gear lever 102 rotates upward to a specific position, the clamping mechanism 104 fixes it. When the gear lever 102 rotates, the gear meshing assembly 101 drives the rotating fixing rod 103 to rotate along with the gear lever 102. When the gear lever 102 is fixed, the rotating fixing rod 103 is fixed in a position perpendicular to the outer wall, so that the support block on the rotating fixing rod 103 can provide support for the ALC plate at a specific position when welding the ALC plate, and fix it in a specific position to facilitate welding.

[0052] As a further embodiment of the present invention, a wedge block 12 is fixedly provided on the base 13. The wedge block 12 contacts the fixing block 11 fixedly provided on the vehicle body below. When the outer wall inside the cavity of the transport mechanism 10 is removed, the mass of the base 13 decreases, the spring 14 below the base 13 deforms, and an upward force is generated on the base 13. The base 13 moves upward, and the wedge block 12 moves upward with the base 13. The wedge block 12 contacts the fixing block 11 and generates a lateral thrust. The movable key 16 at the bottom of the movable base plate 17 slides in the movable groove 15. At this time, the entire transport mechanism 10 moves to the position where the rotating fixing rod 103 contacts the outer wall.

[0053] During operation, the wedge block 12 contacts the fixed block 11 fixed on the vehicle body, reducing the number of inner and outer hanging walls of the transport mechanism 10 and decreasing its mass. The base 13 moves upward under the action of the bottom spring 14. At the same time, the fixed block 11 and the wedge block 12 contact each other, generating a horizontal thrust. The movable key 16 at the bottom of the movable base plate 17 slides in the movable groove 15 until a specific position is reached so that the rotating fixed rod 103 contacts the outer hanging wall, which facilitates the placement of the ALC plate in the required position.

[0054] As a further embodiment of the present invention, a clamping mechanism reset key 18 is installed on the side wall of the transport mechanism 10. After the clamping mechanism reset key 18 is unlocked, the clamping mechanism 104 is opened. A return spring is provided below the gear rocker arm 102. After the clamping mechanism 104 is opened, the gear rocker arm 102 returns to the initial position under the action of the return spring, and the rotating fixed rod 103 returns to the initial position under the action of the gear meshing group 101.

[0055] During operation, after the gear lever 102 is fixed by the clamping mechanism 104, the clamping mechanism reset button 18 can be operated to unlock the clamping mechanism 104 with one click. The gear lever 102 returns to its initial position under the spring force, and the rotating fixing rod 103 also returns to its initial position.
