Description

Technical Field

[0001] This invention relates to the field of aluminum alloy formwork support technology, specifically to a quick-release aluminum alloy formwork support system for concrete disc-type structures. Background Technology

[0002] Aluminum alloy formwork, also known as concrete engineering aluminum alloy formwork, is a new generation of formwork systems following plywood formwork, combined steel formwork systems, steel-framed wood (bamboo) plywood systems, large formwork systems, and early stripping formwork systems. Aluminum alloy formwork uses aluminum alloy profiles as the main material and is manufactured through machining and welding processes, making it suitable for concrete engineering projects.

[0003] Slabs play a supporting and shaping role in concrete pouring. Aluminum alloy formwork is becoming increasingly widely used due to its lightweight and durability. However, the connection between aluminum alloy formwork and between aluminum alloy formwork and supporting components is often achieved by using pins or bolts. This is time-consuming and inefficient during disassembly and assembly. In addition, aluminum alloy formwork is a separate unit after disassembly, which is not only troublesome to assemble, but also makes it very easy for the metal plates to be lost. Summary of the Invention

[0004] The technical problem of this invention is to provide a quick-release aluminum alloy concrete disc-type formwork support system for construction, which can facilitate the rapid installation and disassembly of formwork without using too many pins and bolts.

[0005] To achieve the above objectives, the present invention provides the following technical solution, including a top plate, wherein a plurality of top plates are arranged in a rectangular array and a disc buckle frame is installed at the bottom. A short connecting rod is rotatably connected to the middle of one side of the top plate located at the beginning and end, and the end of the short connecting rod is rotatably connected to the end of the adjacent top plate. The middle of the remaining top plates is rotatably connected to a long connecting rod, and the two ends of the long connecting rod are respectively rotatably connected to the two ends of the adjacent top plates, and the adjacent long connecting rods are respectively located on both sides of the top plate.

[0006] The top plate includes a support part and a connecting part. The connecting part is rotatably connected to both sides of the support part. The support part has an installation groove and a plug-in groove. A connecting rack that moves in opposite directions is slidably connected in the installation groove. A plug-in block that matches the plug-in groove is fixedly connected to the end of each connecting rack. A connecting gear that is rotatably connected to the support part meshes between the connecting racks.

[0007] As a further embodiment of the present invention, the disc buckle frame includes an upright, a horizontal bar connecting adjacent uprights, a diagonal bar, and a cylindrical platform fixedly connected to the support portion. The cylindrical platform has a square groove at its end, and a square block matching the square groove is fixedly connected to the top of the upright.

[0008] As a further embodiment of the present invention, a cylindrical sleeve is fixedly connected to the end of the connecting gear, a sector-shaped groove is provided at the end of the cylindrical sleeve, a sector-shaped block is inserted into the sector-shaped groove, and a limiting sleeve sleeved on the upright is fixedly connected to the sector-shaped block.

[0009] As a further embodiment of the present invention, both the limiting sleeve and the upright are provided with pin grooves, and a pin that penetrates the upright and the limiting sleeve is inserted into the pin groove.

[0010] As a further embodiment of the present invention, both the long connecting rod and the short connecting rod are rotatably connected to a connecting sleeve, the connecting sleeve is threadedly connected to the connecting part, and both the connecting sleeve and the connecting part are provided with a connecting hole.

[0011] As a further embodiment of the present invention, the connecting gear meshes with a loading and unloading gear, and the loading and unloading gear is coaxially fixedly connected with bolts.

[0012] As a further embodiment of the present invention, a counterweight is fixedly connected to the bottom of the upright, a roller is rotatably connected to one side of the bottom of the counterweight, and an anti-slip pad is provided at the bottom of the counterweight.

[0013] As a further embodiment of the present invention, both ends of the support portion and the connecting portion are provided with matching chamfers.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, by moving the top plate of the top layer, the top plate drives the adjacent top plates to unfold via long connecting rods and connecting rods. The second layer of top plates acts on the third layer of top plates via long connecting rods, and so on, until all the top plates are connected end to end, and the top plates are fully unfolded to form a complete longitudinal template. First, the top plates are connected by short connecting rods and long connecting rods, making them less likely to be lost. Second, the chamfers at the ends of adjacent top plates cooperate with each other, allowing the longitudinally adjacent top plates to interact. The interlocking blocks and interlocking slots cooperate to support the transversely adjacent top plates. The template can be spliced ​​without using too many pins or bolts, which enables quick installation and disassembly of the template and avoids the concrete pouring position from sinking due to excessive pressure. It can also avoid height differences between transversely adjacent templates, which would cause a stepped appearance after the concrete has solidified, increasing the time and cost of subsequent grinding. The templates can be spliced ​​without using too many bolts and pins.

[0016] 2. In this invention, when the top plates are connected end to end, the connecting parts on both sides of the support are rotated, causing the connecting parts to drive the short connecting rod and the long connecting rod to flip to the bottom of the top plate, exposing the flat side wall of the top plate. This can avoid the short connecting rod and the long connecting rod from blocking each other, resulting in gaps between the horizontal top plates that cannot be fitted together. When pouring concrete, the concrete will flow away from the gaps between the horizontal top plates or cause protrusions, thus wasting resources or requiring the protrusions to be ground after the concrete has solidified, resulting in increased labor.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figure 1-12 The present invention provides a technical solution: including a top plate 1, the top plate 1 having a plurality of rectangular arrays and a disc buckle frame 15 installed at the bottom, a short connecting rod 23 rotatably connected to the middle of one side of the top plate 1 at the beginning and end, the end of the short connecting rod 23 rotatably connected to the end of the adjacent top plate 1, and the middle of the remaining top plates 1 being rotatably connected to a long connecting rod 24, the two ends of the long connecting rod 24 being rotatably connected to the two ends of the adjacent top plate 1, and the adjacent long connecting rods 24 being located on both sides of the top plate 1 respectively;

[0034] The top plate 1 includes a support part 2 and a connecting part 14. The connecting part 14 is rotatably connected to both sides of the support part 2. The support part 2 has an installation groove 3 and a plug-in groove 4. The mounting groove 3 is slidably connected to a connecting rack 5 that moves in opposite directions. The ends of the connecting rack 5 are all fixedly connected to plug-in blocks 6 that match the plug-in groove 4. The connecting racks 5 are meshed with a connecting gear 7 that is rotatably connected to the support part 2.

[0035] In use, the worker lifts the top plate 1 and moves it to one side. The top plate 1 moves the short connecting rod 23 and the long connecting rod 24. The short connecting rod 23 and the long connecting rod 24 rotate under the action of the adjacent top plate 1. The other end of the long connecting rod 24, which is rotatably connected to the top top plate 1, rotates under the action of the top plate 1 it is rotatably connected to, causing the top and second layer top plates 1 to move further forward. The long connecting rod 24, which is rotatably connected to the second layer top plate 1, rotates under the action of the third layer top plate 1, causing the second layer top plate 1 to continue moving forward, and so on, until the top plates 1 are connected end to end, the top plates 1 are fully unfolded and assembled. To form a complete longitudinal template, firstly, the top plates 1 are connected by short connecting rods 23 and long connecting rods 24, making them less prone to loss. Secondly, the ends of adjacent top plates 1 cooperate with each other, allowing longitudinally adjacent top plates 1 to interact. This enables template splicing without using excessive pins or bolts, achieving both rapid installation and disassembly of the template. It also prevents the concrete pouring location from sinking due to excessive pressure and avoids height differences between laterally adjacent templates, which could result in a stepped appearance after concrete solidification, increasing the time and cost of subsequent grinding. The templates can be joined without using excessive bolts and pins.

[0036] When the top plate 1 is connected end to end, rotate the connecting parts 14 on both sides of the support part 2, so that the connecting parts 14 drive the short connecting rod 23 and the long connecting rod 24 to flip to the bottom of the top plate 1, and the top plate 1 exposes the flat side wall. This can avoid the short connecting rod 23 and the long connecting rod 24 from blocking the gap between the horizontal top plates 1, which would prevent them from fitting together. When pouring concrete, the concrete would flow away from the gap between the horizontal top plates 1 or cause a bulge, which would result in a waste of resources or require grinding of the bulge after the concrete has solidified, which would increase the labor force.

[0037] When the connecting part 14 rotates to the bottom of the support part 2, the disc buckle brackets 15 are installed at both ends of the longitudinal template to support the longitudinal template and make the side walls of the longitudinal template fit together. Then, the connecting gear 7 is rotated, and the connecting gear 7 drives the connecting rack 5 that meshes with it to move outward of the support part 2. The connecting rack 5 drives the insertion block 6 at the end to be inserted into the insertion groove 4 of the side wall of the adjacent support part 2, so that the horizontally adjacent support parts 2 are connected to each other and support each other, avoiding the support part 2 at the concrete pouring position from being subjected to excessive pressure and sinking. It can also avoid the height difference between the horizontally adjacent support parts 2, which would cause the concrete to solidify into a stepped shape, increasing the time and cost of subsequent grinding.

[0038] As a further embodiment of the present invention, the disc buckle frame 15 includes a vertical pole 16, a horizontal bar and a diagonal bar connecting adjacent vertical poles 16, and a cylindrical platform 20 fixedly connected to the support part 2. The cylindrical platform 20 has a square groove 21 at its end, and a square block 22 matching the square groove 21 is fixedly connected to the top of the vertical pole 16.

[0039] When assembling the top plate 1 and the disc buckle frame 15, the square block 22 at the top of the upright 16 is inserted into the square groove 21 in the cylindrical platform 20, so that the upright 16 can support the support part 2. The cooperation between the square groove 21 and the square block 22 can prevent the upright 16 from rotating, thereby affecting the stability of the upright 16; the crossbar is used to strengthen the stability between the uprights 16.

[0040] As a further embodiment of the present invention, a cylindrical sleeve 8 is fixedly connected to the end of the connecting gear 7, and a sector-shaped groove 9 is provided at the end of the cylindrical sleeve 8. A sector-shaped block 10 is inserted into the sector-shaped groove 9, and a limiting sleeve 11 sleeved on the upright 16 is fixedly connected to the sector-shaped block 10.

[0041] When using the device, when installing or disassembling the horizontally adjacent support 2, rotate the limiting sleeve 11. The limiting sleeve 11 drives the sector block 10 to rotate. The sector block 10 drives the cylindrical sleeve 8 to rotate through the sector groove 9. The cylindrical sleeve 8 drives the connecting gear 7 to rotate. The connecting gear 7 pushes the plug block 6 out or pulls it back into the support 2 through the connecting rack 5, moving the loading and unloading point away from the disc buckle frame 15, so that workers have more loading and unloading space, and making it more convenient to connect and separate the horizontally adjacent top plates 1.

[0042] As a further embodiment of the present invention, both the limiting sleeve 11 and the upright 16 are provided with pin grooves 12, and a pin 13 that penetrates the upright 16 and the limiting sleeve 11 is inserted into the pin groove 12.

[0043] After the horizontal top plates 1 are connected to each other, the pins 13 are inserted into the pin slots 12 to limit the position of the limiting sleeve 11, thereby preventing the limiting sleeve 11 from rotating. This would cause the fan-shaped block 10 fixedly connected to it to rotate, causing the connecting gear 7 to rotate and retract the plug block 6 at the end of the connecting rack 5 into the support part 2. This would cause the horizontally adjacent support parts 2 to separate, reducing the connection strength between the horizontally adjacent support parts 2. This would cause the horizontally adjacent support parts 2 to separate or have gaps when pouring concrete, resulting in concrete flowing down or into them, wasting resources or increasing subsequent grinding work. In addition, the limiting sleeve 11 moves the limiting position of the connecting gear 7 downward, thereby facilitating the installation and removal of the pins 13, reducing the time for assembling adjacent support parts 2, and improving work efficiency.

[0044] As a further embodiment of the present invention, both the long connecting rod 24 and the short connecting rod 23 are rotatably connected to the connecting sleeve 25, the connecting sleeve 25 is threadedly connected to the connecting part 14, and both the connecting sleeve 25 and the connecting part 14 are provided with connecting holes 26.

[0045] When the connecting part 14 rotates to the bottom of the support part 2, the horizontally adjacent connecting parts 14 fit together. The connecting rod is passed through the connecting hole 26, and nuts are screwed on both ends of the connecting hole 26 to connect the horizontally adjacent connecting parts 14 together. This makes the connection between the horizontally adjacent top plates 1 more secure. With the help of the plug block 6 and the plug groove 4, gaps between the horizontally adjacent top plates 1 can be further avoided, which would cause concrete to flow down, resulting in waste of resources and increased grinding work after the concrete has solidified. The threaded connection between the connecting sleeve 25 and the connecting part 14 can increase the unfolded length of the interconnected top plates 1, making it suitable for use with top supports of different lengths.

[0046] As a further embodiment of the present invention, the connecting gear 7 meshes with the loading and unloading gear 27, and the loading and unloading gear 27 is coaxially fixedly connected with the bolt 28.

[0047] During installation and disassembly, workers use a wrench to turn bolt 28. Bolt 28 drives loading and unloading gear 27 to rotate, which in turn drives connecting gear 7 to rotate. Connecting gear 7 drives connecting rack 5 to move towards each other, thereby causing the insertion block 6 at the end of connecting rack 5 to extend or retract from the support part 2, so that the horizontally adjacent top plates 1 can be connected or separated. By using loading and unloading gear 27 and bolt 28 to move the loading and unloading action point away from the disc buckle frame 15, workers can have more loading and unloading space, making it easier to connect and separate horizontally adjacent top plates 1.

[0048] As a further embodiment of the present invention, a counterweight 17 is fixedly connected to the bottom of the upright 16, a roller 18 is rotatably connected to one side of the bottom of the counterweight 17, and an anti-slip pad 19 is provided at the bottom of the counterweight 17.

[0049] In use, the counterweight 17 makes the upright 16 more stable, preventing the upright 16 from tilting and causing the top plate 1 to collapse, thus improving the stability of the upright 16. The anti-slip pad 19 increases the friction between the counterweight 17 and the ground, further improving the stability of the upright 16. When moving the upright 16, hold the upright 16 to tilt the counterweight 17, so that the roller 18 contacts the ground, and then drag the counterweight 17 through the upright 16 to move it, reducing the difficulty of moving the disc buckle frame 15.

[0050] As a further embodiment of the present invention, both ends of the support portion 2 and the connecting portion 14 are provided with matching chamfers 29;

[0051] When in use, after the support system is fully deployed, the adjacent support parts 2 are connected end to end, and the chamfers 29 cooperate with each other, so that the adjacent support parts 2 can support each other, and the top plate 1 can interact with each other, making the overall force more uniform, avoiding local subsidence of the top plate 1, which would cause bulging during concrete pouring and increase the grinding time and difficulty after concrete pouring.

[0052] Construction process of disc buckle scaffolding:

[0053] Construction preparation → scaffold positioning → base setting → erection of uprights → installation of longitudinal and transverse horizontal bars → installation of diagonal bracing → installation of top slab.

[0054] 1) The uprights of the disc buckle frame are erected on the foundation floor slab.

[0055] 2) Fixed distance and positioning. Measure the distance between the outer uprights and the wall at one or four corners of the core tube floor slab and mark them; use a steel tape measure to mark the upright positions and mark them with chalk; the base should be accurately placed on the positioning line, and the base must be laid flat and not suspended in the air.

[0056] 3) The scaffolding should be erected in the order of first erecting uprights, then horizontal bars, and then diagonal bars to form basic scaffolding units. These units should be expanded to form an overall scaffolding system.

[0057] 4) The pins of the crossbar fastener and the connecting plate should be hammered to the specified insertion depth mark. The crossbar is connected with steel pipe fasteners.

[0058] 5) After each step of the formwork support is erected, the horizontal bar spacing, the longitudinal and transverse spacing of the uprights, the vertical deviation of the uprights, and the horizontal deviation of the horizontal bars should be adjusted in a timely manner. The vertical deviation of the uprights should not exceed 1 / 500 of the total height of the formwork support frame, and should not exceed 50mm.

[0059] 6) The scaffolding of this project is designed as an early formwork stripping system. Therefore, when setting up continuous formwork scaffolding on multi-story slabs, it should be ensured that the support uprights of the upper and lower floors are on the same axis.

[0060] 7) Before pouring concrete, the construction management personnel should organize the inspection of the erected scaffolding and confirm that it meets the requirements of the special construction plan before pouring concrete.
