Description

Technical Field

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

[0002] Currently, China is in a stage of rapid urbanization development, and the task of constructing urban high-rise residential buildings is arduous. High-rise and super-high-rise buildings are mainly made of reinforced concrete. Building formwork is an essential construction material and important equipment. Compared with aluminum formwork, magnesium formwork has the advantages of the same service life, recyclability, etc., and is lighter in weight and stronger in corrosion resistance. It has gradually replaced aluminum formwork as the main equipment used in construction. And because the formwork structure needs to bear the weight of concrete, during the actual construction process, in order to improve the installation strength and bearing capacity of the formwork structure, corresponding support members need to be configured for the formwork structure. However, during the use of existing support members, due to their large mass and long length, it is difficult to erect and lift them. Especially when operating in a small space, it is time-consuming and laborious. And during the process of lifting the support members, it is extremely easy to tilt due to uneven force, posing a great safety hazard, and the operability and reliability are poor.

[0003] Therefore, there is an urgent need for a support device for magnesium formwork construction in buildings to solve the defects existing in the actual use process of the above-mentioned existing support members. Summary of the Invention

[0004] This application proposes an auxiliary support device for magnesium formwork construction in high-rise buildings, which has the advantages of low operation difficulty, time-saving and labor-saving when erecting and lifting it, and is not easy to tilt during the process of erection and lifting. It is used to solve the problem that during the use of existing support members, due to their large mass and long length, it is difficult to erect and lift them, especially when operating in a small space, it is time-consuming and laborious, and during the process of lifting the support members, it is extremely easy to tilt due to uneven force.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: 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 threadedly connected to 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, a second support rod being movably connected inside the first support rod and having a top in contact with the bottom end of the magnesium mold, and the top of the lifting mechanism being pin-connected 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 comprising a shaft sleeve movably sleeved on the top of the outer surface of the adjusting nut, a group of first connecting rods being pin-connected on both sides of the outer surface of the shaft sleeve, and a second connecting rod being pin-connected on the top of the first connecting rod. The cam is an angular movement of the second lever arm extending along the length of the lever arm to move the lever arm in a direction of rotation relative to the second lever arm. The cam is secured to the second lever arm with a plurality of levers extending along the length of the lever arm. The cam is secured to the second lever arm with a plurality of levers extending along the length of the lever arm.

[0006] 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 pressing plates are fixedly connected to the second support rod through limiting pins.

[0007] Furthermore, a positioning hole is provided on the middle part of the outer surface of the first support rod, which passes through the first support rod and the second support rod. When the pressure plate needs to be fixedly connected with the next group 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 and assembled. When the top end of the pressure plate is fixed to the next group of through holes on the second support rod by the limit pin, the positioning pin is removed, and the second support rod can be driven to move upward or downward in the process of rotating the lifting nut.

[0008] Furthermore, the displacement of the adjusting nut when it rotates 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. This prevents the support device from being able to be adjusted to form effective support for the magnesium mold. The operation is simple and easy to use.

[0009] Furthermore, when the first connecting rod and the second connecting rod change from the minimum bending angle to the maximum bending angle under the action of the threaded tie 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 cooperate with the positioning pin to gradually lift the second support rod until its top end contacts the bottom end of the magnesium mold.

[0010] Furthermore, the other sides of the pin joints between the two groups of the first connecting rod and the second connecting rod are connected by a linkage cylinder in a transmission manner, and the two cylinders on the linkage cylinder are interconnected by a communicating pipe, and a control valve is provided on the communicating pipe. When the lifting mechanism operates, the control valve is opened to make the two cylinders on the linkage cylinder communicate with each other. When the lifting mechanism does not operate, the control valve is closed, so as to maintain the relative stretching length of the linkage cylinder, and effectively balance the forces on the left and right sides between the two groups of the first connecting rod and the second connecting rod.

[0011] Furthermore, the inside of the linkage cylinder is filled with inert gas with full volume, so as to effectively avoid the phenomenon that the forces on both sides of the first connecting rod and the second connecting rod are unbalanced due to the volume change of the internal gas caused by thermal expansion and contraction during the process of the linkage cylinder being stressed.

[0012] The beneficial effects of the present invention are as follows: An auxiliary support device for magnesium mold construction of high-rise buildings provided by the present application, for the setting of the lifting mechanism and its upper structure, can use the lifting mechanism to lift the second support rod, which is time-saving and labor-saving and will not cause the second support rod to tilt due to unbalanced force. During the process of lifting the second support rod, the lifting height of the second support rod can be finely adjusted by using the adjusting nut to prevent the problem that when the distance between the top end of the second support rod and the magnesium mold is less than the distance between adjacent through holes on the second support rod, the support device cannot be adjusted to effectively support the magnesium mold. The operation is simple and convenient, and the labor intensity of the operator is effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, an auxiliary support device for high-rise building magnesium formwork construction includes a first support rod 1 whose bottom end is fixedly installed 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 pin-connected with 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, a group of first connecting rods 8 are pinned on both sides of the outer surface of the sleeve 7, and a second connecting rod 9 is pinned on the top of the first connecting rod 8, and a pressure plate 10 whose inner wall is adapted to the outer surface of the second support rod 4 is pinned on one end of the second connecting rod 9, and a connecting hole 11 is provided inside the pressure plate 10 to penetrate 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 tie rod 13, and a lifting nut 14 is provided on one side of the outer surface of the threaded tie rod 13, so that 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 open 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; 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.

[0017] like Figure 1, Figure 2 As shown, in the present 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 pressing plates 10 are fixedly connected to the second support rod 4 through the limiting pins 12 .

[0018] like Figure 1 , Figure 2 As shown, in the present technical scheme, a positioning hole 5 running through the left and right is provided in the middle of the outer surface of the first support rod 1. 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.

[0019] like Figure 2 , Figure 4 As shown, in the present technical solution, the displacement of the adjusting nut 2 when it rotates up and down 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 supporting device cannot be adjusted to form effective support for the magnesium mold. The operation is simple and easy to use.

[0020] 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.

[0021] like Figure 2 As 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 rods 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 by 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 rods 9.

[0022] In this technical solution, the linkage cylinder 15 is filled with inert gas at full volume to effectively avoid the phenomenon that the force on both sides between the first connecting rod 8 and the second connecting rod 9 is unbalanced due to the volume change of the gas inside the linkage cylinder 15 caused by thermal expansion and contraction during the force application process.
