Description

Technical Field

[0001] The present application relates to the technical field of formwork support components, and in particular to an auxiliary support device for magnesium formwork construction of high-rise buildings. Background Art

[0002] At present, my country is in a stage of rapid urbanization. The construction of high-rise residential buildings in cities and towns is a heavy task. High-rise and super-high-rise buildings are mainly made of reinforced concrete. Building formwork is an indispensable construction material and important equipment. Compared with aluminum formwork, magnesium formwork maintains the same advantages of service life and recyclability, while being lighter and more corrosion-resistant. It has gradually replaced aluminum formwork as the main equipment used in construction.

[0003] And because the formwork structure needs to bear the weight of concrete, in the actual construction process, in order to improve the installation strength and pressure-bearing capacity of the formwork structure, the formwork structure needs to be equipped with corresponding supporting components. However, during use, the existing supporting components are difficult to erect and lift due to their large mass and long length. Especially when operating in a small space, it is time-consuming and labor-intensive. In the process of lifting the supporting components, it is very easy to tilt due to uneven force, which poses a major safety hazard and has poor operability and reliability.

[0004] Therefore, there is an urgent need for a supporting device for construction of magnesium formwork to solve the defects of the above-mentioned existing supporting components during actual use. Summary of the Invention

[0005] The present application proposes an auxiliary support device for the construction of magnesium formwork for high-rise buildings, which has the advantages of low difficulty in operation when erecting and lifting, saving time and effort, and not easy to tilt during the erection and lifting process. It is used to solve the problem that the existing support components are difficult to erect and lift due to their large mass and long length during use, especially when operating in a small space, which is time-consuming and labor-intensive, and are very likely to tilt due to uneven force during the lifting process of the support components.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: an auxiliary support device for the construction of magnesium formwork for high-rise buildings, comprising a first support rod fixedly installed at the bottom end on the construction ground, an adjusting nut being threaded on the top of the outer surface of the first support rod, and a lifting mechanism being movably sleeved on the top of the outer surface of the adjusting nut, an internal movably connected to a second support rod whose top end contacts the bottom end of the magnesium formwork, and the top of the lifting mechanism is pinned to the second support rod, thereby effectively supporting the second support rod and driving the second support rod to move upward along the trajectory of the first support rod in the process of triggering the lifting mechanism, the lifting mechanism comprises a shaft sleeve movably sleeved on the top of the outer surface of the adjusting nut, a group of first connecting rods are pinned on both sides of the outer surface of the shaft sleeve, and the top of the first connecting rod is pinned to the second connecting rod. The cam is secured to the second support rod by a pin at one end thereof and has a plurality of holes therethrough, the holes being adapted to move the cam forward and downward, so that the cam can be secured to the second support rod and the second support rod can be secured therethrough.

[0007] Furthermore, a plurality of through holes arranged in a linear array are provided inside the second support rod, and under the action of the through holes, the two groups of pressure plates are fixedly connected to the second support rod through limiting pins.

[0008] Furthermore, a positioning hole is provided on the left and right sides of the outer surface of the first support rod. When the pressure plate needs to be fixedly connected to the next set of through holes on the second support rod, the first support rod and the second support rod are pre-fixed by the positioning pin to prevent relative sliding between the first support rod and the second support rod when the connection between the pressure plate and the second support rod is disassembled. When the top end of the pressure plate is fixed to the next set of through holes on the second support rod by the limit pin, the positioning pin is removed, and then the second support rod can be driven to move upward or downward during the process of rotating the lifting nut.

[0009] Furthermore, the displacement of the adjusting nut when it is rotated is equal to the distance between adjacent through holes on the second support rod. Therefore, in the process of lifting the second support rod, the adjusting nut can be used to fine-tune the lifting height of the second support rod to prevent the distance between the top end of the second support rod and the magnesium mold from being less than the distance between adjacent through holes on the second support rod, thereby preventing the support device from being unable to be adjusted to effectively support the magnesium mold. The operation is simple and easy to use.

[0010] Furthermore, when the first connecting rod and the second connecting rod are bent from the minimum bending angle to the maximum bending angle under the action of the threaded pull rod, the relative displacement height of the top end of the second connecting rod is greater than the distance between adjacent through holes on the second support rod, and then cooperates with the positioning pin to gradually lift the second support rod until its top end contacts the bottom end of the magnesium mold.

[0011] Furthermore, the other side of the pin joint between the two groups of the first connecting rod and the second connecting rod is connected through a linkage cylinder transmission, and the two groups of cylinder bodies on the linkage cylinder are connected to each other through a connecting pipe, and a control valve is provided on the connecting pipe. When the lifting mechanism is in operation, the control valve is opened so that the two groups of cylinder bodies on the linkage cylinder are connected to each other, and when the lifting mechanism is not in operation, the control valve is closed, thereby maintaining the relative stretching length of the linkage cylinder to effectively balance the forces on the left and right sides between the two groups of the first connecting rod and the second connecting rod.

[0012] Furthermore, the interior of the linkage cylinder is filled with a full volume of inert gas to effectively avoid the occurrence of unbalanced force between the first connecting rod and the second connecting rod due to the volume change of the internal gas of the linkage cylinder due to thermal expansion and contraction when the linkage cylinder is subjected to force.

[0013] The beneficial effects of the present invention are as follows:

[0014] The present application provides an auxiliary support device for the construction of magnesium formwork for high-rise buildings. Regarding the setting of the lifting mechanism and the structure above it, the lifting mechanism can be used to lift the second support rod, which saves time and effort and will not cause the second support rod to tilt due to uneven force. In the process of lifting the second support rod, the adjusting nut can be used to fine-tune the lifting height of the second support rod to prevent the problem that the support device cannot be adjusted to effectively support the magnesium mold when the distance between the top of the second support rod and the magnesium mold is less than the distance between adjacent through holes on the second support rod. The operation is simple and easy to use, and the labor intensity of the operator is effectively reduced. BRIEF DESCRIPTION OF THE 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.

[0022] like Figure 1 As shown, an auxiliary support device for the construction of magnesium formwork for high-rise buildings includes a first support rod 1 fixedly installed at its bottom end on the construction ground, an adjusting nut 2 is threadedly connected to the top of the outer surface of the first support rod 1, and a lifting mechanism 3 is movably sleeved on the top of the outer surface of the adjusting nut 2, a second support rod 4 whose top end contacts the bottom end of the magnesium formwork is movably connected inside the first support rod 1, and the top end of the lifting mechanism 3 is pinned to the second support rod 4, thereby effectively supporting the second support rod 4 and driving the second support rod 4 to move upward along the trajectory of the first support rod 1 in the process of triggering the lifting mechanism 3, as shown in FIG. Figure 2 、 Figure 3 As shown, the lifting mechanism 3 includes a sleeve 7 movably sleeved on the top of the outer surface of the adjusting nut 2, and a group of first connecting rods 8 are pinned on both sides of the outer surface of the sleeve 7, and the top of the first connecting rod 8 is pinned to the second connecting rod 9, and one end of the second connecting rod 9 is pinned to a pressure plate 10 whose inner wall is adapted to the outer surface of the second support rod 4. The interior of the pressure plate 10 is provided with a connecting hole 11 running through it on the left and right, and the two groups of pressure plates 10 are fixedly connected to the second support rod 4 by a limit pin 12, and one side of the pin connection point between the two groups of first connecting rods 8 and the second connecting rod 9 is connected by a threaded pull rod 13 for transmission, and a lifting nut 14 is provided on one side of the outer surface of the threaded pull rod 13, and then in the process of rotating the lifting nut 14, the two groups of first connecting rods 8 and the second connecting rod 9 can be forced to shrink inward or expand outward, and the second support rod 4 on the first support rod 1 can be driven to move upward or downward, so that the top of the second support rod 4 is against the magnesium mold to support it;

[0023] In the process of lifting the second support rod 4 by using the lifting mechanism 3, the labor intensity of the operator can be effectively reduced, and the second support rod 4 will not be tilted due to uneven force.

[0024] like Figure 1 、 Figure 2 As shown, in this technical solution, a plurality of through holes arranged in a linear array are provided inside the second support rod 4 , and under the action of the through holes, the two groups of pressure plates 10 are fixedly connected to the second support rod 4 through the limiting pins 12 .

[0025] like Figure 1 、 Figure 2 As shown, in the present technical solution, a positioning hole 5 is provided in the middle of the outer surface of the first support rod 1, which passes through the left and right. When it is necessary to fix the pressure plate 10 with the next group of through holes on the second support rod 4, the first support rod 1 and the second support rod 4 are pre-fixed by the positioning pin 6 to prevent relative sliding between the first support rod 1 and the second support rod 4 when the connection between the pressure plate 10 and the second support rod 4 is disassembled. When the top end of the pressure plate 10 is fixed to the next group of through holes on the second support rod 4 by the limit pin 12, the positioning pin 6 is removed, and then the second support rod 4 can be driven to move upward or downward in the process of rotating the lifting nut 14.

[0026] like Figure 2 、 Figure 4 As shown, in the present technical solution, the displacement of the adjusting nut 2 when it is rotated is equal to the distance between adjacent through holes on the second support rod 4. Therefore, in the process of lifting the second support rod 4, the adjusting nut 2 can be used to fine-tune the lifting height of the second support rod 4 to prevent the distance between the top end of the second support rod 4 and the magnesium mold from being less than the distance between adjacent through holes on the second support rod 4. The support device cannot be adjusted to form effective support for the magnesium mold. The operation is simple and easy to use.

[0027] like Figure 3 As shown, in the present technical solution, when the first connecting rod 8 and the second connecting rod 9 are bent from the minimum angle to the maximum angle under the action of the threaded pull rod 13, the relative displacement height of the top end of the second connecting rod 9 is greater than the distance between adjacent through holes on the second support rod 4, and then cooperates with the positioning pin 6 to gradually lift the second support rod 4 until its top end contacts the bottom end of the magnesium mold.

[0028] like Figure 2As shown, in the present technical solution, the other side of the pin joint between the two groups of first connecting rods 8 and the second connecting rod 9 is connected by a linkage cylinder 15, and the two groups of cylinder bodies on the linkage cylinder 15 are connected to each other through a connecting pipe 16, and a control valve is provided on the connecting pipe 16. When the lifting mechanism 3 is in action, the control valve is opened so that the two groups of cylinder bodies on the linkage cylinder 15 are connected to each other, and when the lifting mechanism 3 is not in action, the control valve is closed, thereby maintaining the relative stretching length of the linkage cylinder 15 to effectively balance the forces on the left and right sides between the two groups of first connecting rods 8 and the second connecting rod 9.

[0029] In this technical solution, the interior of the linkage cylinder 15 is filled with a full volume of inert gas to effectively avoid the occurrence of unbalanced force between the first connecting rod 8 and the second connecting rod 9 due to the volume change of the internal gas of the linkage cylinder 15 due to thermal expansion and contraction during the force application process.
