Description

Technical Field

[0001] This utility model belongs to the field of support structure technology, specifically relating to an aluminum formwork support structure for building composite slabs. Background Technology

[0002] Composite slabs are a new type of structure combining precast and cast-in-place concrete, widely used in prefabricated building systems. To ensure the composite slabs maintain precise height and level during hoisting, positioning, and casting, specialized aluminum formwork and supporting structures are typically used for fixation. As a lightweight, high-strength, and easily assembled / disassembled formwork material, the adjustability, clamping stability, and ease of operation of the supporting system directly impact construction efficiency and structural accuracy.

[0003] Currently, most common aluminum formwork support structures use fixed-length steel pipes or multi-section plug-in uprights, with height adjustment and locking via locking pins, threaded sleeves, etc. However, when using these structures, manual disassembly and assembly of multiple parts is required, making adjustments cumbersome, laborious, and inefficient, and it is difficult to quickly adapt to the support needs of aluminum formwork with different widths and installation heights. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a building composite slab aluminum formwork support structure. The entire height adjustment process is more labor-saving and can well meet the support of aluminum formwork at different installation heights. Compared with the conventional support structure in the prior art, it can better adapt to the support, clamping and fixing of aluminum formwork of different widths, while the adjustment is also more convenient and does not require climbing.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a building composite slab aluminum formwork support structure, including an aluminum formwork and a support structure, characterized in that the support structure includes: a base, a bottom support structure, an adjustment drive mechanism, a top support structure, and an adjustable clamping and fixing structure; the bottom support structure includes a hollow support column fixed to the top of the base, and a bearing is fixedly provided at the top of the hollow support column; the adjustment drive mechanism includes an adjustment rotating seat rotatably connected to the bearing, and a first threaded hole is provided through the top and bottom of the adjustment rotating seat; the top support structure includes a hollow threaded rod threadedly connected to the first threaded hole, a guide block is installed at the bottom of the hollow threaded rod, a first rotating shaft is rotatably installed inside the hollow threaded rod, a first bevel gear is provided at the top of the first rotating shaft, and a drive structure is provided at the bottom of the guide block; the adjustable clamping and fixing structure includes a slide fixed above the hollow threaded rod, a sliding groove is provided on the inner side of the slide, a slider is slidably installed on the inner side of the sliding groove and a bidirectional lead screw is rotatably installed thereon, an L-shaped clamping support plate is provided at the top of the slider, and a fourth bevel gear is fixedly sleeved on the outer side of the bidirectional lead screw.

[0006] To improve the stability of this device during installation:

[0007] As a further improvement to the above technical solution: the bottom of the base is provided with a rubber anti-slip pad.

[0008] The rubber anti-slip pads on the bottom of the base can prevent slipping and improve the stability of the device during installation.

[0009] In order for the hollow threaded rod to be stably driven to rise and fall by the adjustable swivel:

[0010] As a further improvement to the above technical solution: the hollow support column is provided with a guide groove on its inner side, and a strip groove is provided between the inner and outer sides of the hollow support column, and the guide block and the guide groove are slidably engaged.

[0011] When the hollow threaded rod is driven by the adjusting swivel, the guide block slides along the guide groove to prevent the hollow threaded rod from rotating.

[0012] To make it easier to rotate the adjustment knob:

[0013] As a further improvement to the above technical solution: the side of the adjusting pivot is provided with a rotating connecting seat, and a first rotating rod is rotatably installed on the inner side of the rotating connecting seat.

[0014] When not in use, the first rotating rod can be folded downwards vertically by rotating the connecting seat. When in use, hold the first rotating rod and rotate it to a horizontal position by rotating the connecting seat. The rotating seat can then be easily adjusted by rotating the first rotating rod.

[0015] To lock the adjustment knob:

[0016] As a further improvement to the above technical solution: a second threaded hole is provided between the inner and outer sides of the adjusting rotary seat, the second threaded hole is threadedly connected to the locking screw, and one end of the locking screw is connected to a second rotating rod.

[0017] When the horizontal support part of the L-shaped clamping support plate contacts the bottom of the aluminum mold, the locking screw in the second threaded hole is tightened by the second rotating rod, and the adjusting seat is locked by end face friction to keep the hollow threaded rod at the current height.

[0018] To drive the first rotating shaft to rotate:

[0019] As a further improvement to the above technical solution: the drive structure includes a transmission chamber installed below the guide block, the bottom end of the first rotating shaft penetrates into the interior of the transmission chamber and is connected to a second bevel gear, the side plate of the transmission chamber is through which the second rotating shaft is rotatably installed, one end of the second rotating shaft located inside the transmission chamber is connected to a third bevel gear, the third bevel gear meshes with the second bevel gear, and the other end of the second rotating shaft passes through a strip-shaped through groove and is connected to a knob.

[0020] Rotating the knob drives the second shaft to rotate. One end of the second shaft, located in the transmission chamber, is connected to the third bevel gear. Through the meshing transmission between the third bevel gear and the second bevel gear, the second bevel gear, together with the first shaft, rotates.

[0021] To lock the second shaft:

[0022] As a further improvement to the above technical solution: the portion of the second rotating shaft located outside the hollow support column is provided with external threads and is threadedly connected to a locking sleeve.

[0023] After the locking sleeving is tightened, an axial preload is generated between the inner thread of the locking sleeving and the outer thread of the second shaft. This force forces the end face of the locking sleeving to press tightly against the outer wall of the hollow support column, forming a normal pressure. This generates static friction between the end face of the locking sleeving and the outer wall of the hollow support column, preventing the shaft from rotating due to vibration or external force, thus achieving circumferential locking.

[0024] As a further improvement to the above technical solution: the top of the hollow threaded rod is provided with a threaded seat, and the slide is threaded and fixed to the threaded seat.

[0025] To drive the bidirectional lead screw to rotate:

[0026] As a further improvement to the above technical solution: the top end of the first rotating shaft penetrates into the inner side of the slide groove, and the first bevel gear meshes with the fourth bevel gear.

[0027] When the first shaft rotates, the first bevel gear at its top meshes with the fourth bevel gear on the outside of the double-acting lead screw, driving the double-acting lead screw to rotate in the slide groove.

[0028] To drive the slider to move within the groove:

[0029] As a further improvement to the above technical solution: the bidirectional lead screw adopts a trapezoidal lead screw, and the bidirectional lead screw and the slider are connected by threads.

[0030] The double-acting lead screw adopts a trapezoidal lead screw. Due to its large thread contact surface and high friction coefficient, the trapezoidal lead screw (such as the 30° standard type) can achieve self-locking. When the double-acting lead screw rotates in the slide groove, it drives the slider to move through the threaded transmission between the slider and the slide block.

[0031] The beneficial effects of this utility model are as follows:

[0032] 1. The entire height adjustment process of this device is relatively labor-saving and can well meet the support of aluminum molds with different installation heights; the clamping width adjustment of the adjustable clamping and fixing mechanism is stepless through multi-stage transmission of bevel gear - rotating shaft - double-sided lead screw, which can better adapt to the support of aluminum molds with different widths. Moreover, the knob used to drive the adjustment of the clamping width is located at a lower position. Compared with the conventional support structure in the existing technology, it is more convenient to adjust while clamping and fixing, without the need to climb high.

[0033] 2. The deployment and adjustment of this device do not require any other tools, and tool-free deployment and support can be achieved. When not in use, the hollow threaded rod can be stored in the hollow support column, which reduces the overall size of the device and makes it easier to store and transport.

[0034] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figures 1-5 As shown, this utility model relates to an aluminum formwork support structure for composite building slabs, including an aluminum formwork 1 and a support structure. The support structure includes a base 2 and a bottom support structure 3 disposed in the middle of the upper surface of the base 2. The bottom of the base 2 is provided with a rubber anti-slip pad, which plays an anti-slip role and improves the stability of the device during installation. The bottom support structure 3 includes a hollow support column 31 fixed in the middle of the upper surface of the base 2. Two sets of guide grooves 32 are vertically symmetrically arranged on the inner side of the hollow support column 31. A strip-shaped through groove 33 is vertically penetrating the hollow support column 31. The angle between the strip-shaped through groove 33 and the hollow support column 31, and the angle between the guide groove 22 and the center line of the hollow support column 31, are right angles. A bearing 34 is installed on the top of the hollow support column 31. An adjustment drive mechanism 4 is disposed at the upper end of the top support structure 3 and located outside the bearing 24. The adjustment drive mechanism 4 can rotate relative to the hollow support column 31.

[0044] The adjustment drive mechanism 4 of this embodiment includes an adjustment rotating seat 41 fixedly connected to the bearing 34. A first threaded hole 42 is provided between the top and bottom of the adjustment rotating seat 41. A top support structure 5 is disposed in the first threaded hole 42. The top support structure 5 of this embodiment includes a hollow threaded rod 51 threadedly connected to the first threaded hole 42. The lower part of the hollow threaded rod 51 extends into the hollow support column 31, and a guide block 52 is installed at the bottom. The guide block 52 is slidably disposed in the guide groove 32. When the hollow threaded rod 51 is driven up and down by the adjustment rotating seat 41, the guide block 52 slides up and down along the guide groove 32 for sliding guidance, while preventing the hollow threaded rod 51 from rotating. A first rotating shaft 54 ​​is disposed inside the hollow threaded rod 51 through the guide block 52 and can rotate relative to the guide block 52. The top of the first rotating shaft 54 ​​extends into the adjustable clamping and fixing structure 6, and a drive structure is provided at the bottom.

[0045] Specifically, a threaded rod 51 has a threaded seat 53 at its top, and an adjustable clamping and fixing structure 6 is fixed to the threaded seat 53. In this embodiment, the adjustable clamping and fixing structure 6 includes a slide block 61 fixed above the hollow threaded rod 51. The slide block 61 has a slide groove 62 inside. A first rotating shaft 54 ​​passes through the threaded seat 53 and the slide block 61, extends into the slide groove 62, and has a first bevel gear 55 at its top. Two sets of sliders 63 are slidably installed at both ends of the slide groove 62. A bidirectional lead screw 65 is provided between the two sets of sliders 63. The bidirectional lead screw 65 is rotatably installed in two sets of vertically spaced mounting seats 67, which serve as support and limiters. A fourth bevel gear 66 is provided on the bidirectional lead screw 65 between the two sets of mounting seats 67. The fourth bevel gear 66 meshes with the first bevel gear 55. An L-shaped clamping support plate 64 is provided at the top of the slider 63. Two sets of L-shaped clamping plates 64 are arranged opposite to each other, and the aluminum mold 1 is placed between the two sets of L-shaped clamping plates 64.

[0046] When the first rotating shaft 54 ​​rotates, the first bevel gear 55 and the fourth bevel gear 66 at its top mesh to drive the bidirectional lead screw 65 to rotate. The bidirectional lead screw 65 is a trapezoidal lead screw with a threaded connection to the slider 63. The trapezoidal lead screw (such as the 30° standard type) can achieve self-locking due to its large thread contact surface and high coefficient of friction. When the bidirectional lead screw 65 rotates in the slide groove 62, it drives the slider 63 to move horizontally through the threaded transmission with the slider 63. This, in turn, causes the L-shaped clamping plate 64 to slide horizontally.

[0047] The drive structure includes a transmission chamber 56 mounted below the guide block 52. The bottom end of the first rotating shaft 54 ​​penetrates the interior of the transmission chamber 56 and is connected to a second bevel gear 57. The second rotating shaft 58 penetrates the side wall of the transmission chamber 56 and can rotate relative to it. One end of the second rotating shaft 58 located inside the transmission chamber 56 is connected to a third bevel gear 59, which meshes with the second bevel gear 57. The end of the second rotating shaft 58 away from the transmission chamber 56 extends through a strip-shaped through slot 33 and is connected to a knob 510. Rotating the knob 510 drives the second rotating shaft 58 to rotate. Through the meshing transmission between the third bevel gear 59 and the second bevel gear 57, the first rotating shaft 54 ​​is driven to rotate. In turn, through the meshing action of the first bevel gear 55 and the fourth bevel gear 66, the bidirectional lead screw 65 is driven to rotate, enabling the L-shaped clamping plate 64 to move horizontally.

[0048] To ensure a stable connection, the portion of the second rotating shaft 58 located outside the hollow support column 31 is provided with an external thread and threadedly connected to a locking sleeve 511. After the locking sleeve 511 is tightened, its end face is forced to press tightly against the outer wall of the hollow support column 31, forming a normal pressure. This generates static friction between the end face of the locking sleeve 511 and the outer wall of the hollow support column 31, preventing the rotating shaft from rotating due to vibration or external force, thus achieving circumferential locking.

[0049] For ease of operation, a rotating connecting seat 43 is provided on one side of the adjusting seat 41. A first rotating rod 44 is rotatably mounted on the inner side of the rotating connecting seat 43. When not in use, the first rotating rod 44 can be folded downwards and vertically through the rotating connecting seat 43. When in use, hold the first rotating rod 44 and rotate it to a horizontal position through the rotating connecting seat 43. The adjusting seat 41 can then be easily rotated with the help of the first rotating rod 44.

[0050] To achieve a high level of locking, a second threaded hole 45 is horizontally provided on the other side of the adjusting rotary seat 41. The second threaded hole 45 is used to install the locking screw 46, and the free end of the locking screw 46 is connected to a second rotating rod 47. When the horizontal support part of the L-shaped clamping support plate 64 contacts the bottom of the aluminum mold 1, the locking screw 46 in the second threaded hole 45 is tightened by the second rotating rod 47. The adjusting rotary seat 41 is locked by friction between the end face of the locking screw 46 and the hollow support column 31, so that the hollow threaded rod 51 maintains its current height.

[0051] This device can support aluminum molds at different installation heights. The clamping width of the adjustable clamping and fixing mechanism is adjusted through a multi-stage transmission of bevel gear, rotating shaft, and double-acting screw, which can better adapt to the support of aluminum molds of different widths. Moreover, the knob 510 used to drive and adjust the clamping width is located relatively low. Compared with the conventional support structure in the existing technology, it is more convenient to adjust while clamping and fixing, without the need to climb high.

[0052] Working principle and usage process of this utility model:

[0053] In use, the operator first places the base 2 on a flat surface, rotates to loosen the locking sleeve 511, releasing the locking sleeve 511 from locking the second rotating shaft 58, and rotates the knob 510 to drive the second rotating shaft 58 to rotate. The second rotating shaft 58 drives the first rotating shaft 54 ​​to rotate through the meshing transmission between the third bevel gear 59 and the second bevel gear 57. Due to the meshing action between the first bevel gear 55 and the fourth bevel gear 66 at the top of the first rotating shaft 54, the double-acting lead screw 65 is driven to rotate in the slide groove 62. Through the threaded transmission between the lead screw and the slider 63, the slider 63 is driven to move the L-shaped clamping support plate 64 synchronously in opposite directions, so that the distance between the vertical plates of the two sets of L-shaped clamping support plates 64 is adapted to the width of the aluminum mold 1. Then, according to The installation height of the composite aluminum mold 1 (usually 2.5-4m) is adjusted using the adjustment drive mechanism 4 to adjust the height of the top support structure. During adjustment, first rotate the second rotating rod 47 to loosen the locking screw 46 in the second threaded hole 45. Then, grasp the first rotating rod 44 and rotate it to a horizontal position via the rotating connecting seat 43. The first rotating rod 44 can then be used to easily rotate the adjusting seat 41. Rotating the adjusting seat 41 at the top of the hollow support column 31 drives the hollow threaded rod 51 through the threaded transmission between the first threaded hole 42 and the hollow threaded rod 51, causing the adjustable clamping and fixing structure 6 to rise. At this time, the guide block 52 slides along the guide groove 32 to prevent the hollow threaded rod 51 from rotating. When the L-shaped clamping... When the horizontal support portion of the support plate 64 contacts the bottom of the aluminum mold 1, the locking screw 46 in the second threaded hole 45 is tightened by the second rotating rod 47, and the adjusting rotating seat 41 is locked by end face friction. The entire height adjustment process of this device is relatively effortless and achieves stepless adjustment, meeting the support requirements of aluminum molds at different installation heights. During this process, due to the self-locking between the slider 63 and the bidirectional lead screw 65, the L-shaped clamping support plate 64 can maintain its current position. After the height adjustment is completed, the clamping width of the adjustable clamping fixing mechanism can be readjusted, causing the two sets of L-shaped clamping support plates 64 to move synchronously towards each other, thereby allowing the vertical plates of the two sets of L-shaped clamping support plates 64 to align with... The aluminum mold is securely clamped by contacting both sides. In this process, the knob 510 is first rotated in the opposite direction to drive the second shaft 58 and the third bevel gear 59 to rotate in the opposite direction, thereby driving the second bevel gear 57 and the first shaft 54 ​​and the first bevel gear 55 to rotate in the opposite direction. The first bevel gear 55 drives the fourth bevel gear 66 and the bidirectional lead screw 65 to rotate in the opposite direction. Through the threaded transmission between the first bevel gear 55 and the slider 63, the L-shaped clamping support plate 64 is driven to move synchronously in opposite directions until the side plate of the L-shaped clamping support plate 64 is in close contact with the side of the aluminum mold. Finally, the locking nut 511 is tightened to fix the second shaft 58, so as to prevent the L-shaped clamping support plate 64 from loosening its clamping of the aluminum mold due to accidental contact with the knob 510 during subsequent use.
