Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and more specifically, to a temporary support device with adjustable height. Background Technology

[0002] Temporary support devices are typically used to assist in the precise positioning and welding of large-span steel structural components such as steel beams and trusses until the structure forms a complete load-bearing system. Temporary support devices usually consist of a lower support platform and a support frame. Traditional steel support frames are heavy, lack flexibility, are difficult to adjust, and have poor stability at higher levels. Furthermore, their top support platforms are limited and cannot adapt to various structural applications. Traditional temporary supports for large-span spatial truss structures suffer from low standardization, large footprint, difficulty in installation and dismantling, low construction efficiency, and poor adaptability.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Embodiments of this application provide a temporary support device with adjustable height, including a bracket 100 and a lifting assembly 200.

[0037] like Figure 10 As shown, bracket 100 is set vertically.

[0038] For example, the bracket 100 is vertically fixed to the ground. However, in another embodiment, such as Figure 10 As shown, the bracket 100 is fixedly mounted on the base 300, which is fixedly mounted on the ground. The base 300 provides a horizontal mounting surface for the bracket 100.

[0039] like Figure 9 and Figure 10 As shown, the lifting assembly 200 is disposed at the top of the bracket 100, and the lifting assembly 200 is used to provide a height-adjustable support position 260.

[0040] like Figure 6 As shown, the lifting assembly 200 includes a telescopic rod 210, a support column 220, and a connecting beam 230. At least one telescopic rod 210 is supported at each end of the connecting beam 230. The telescopic rod 210 is vertically fixed to the top of the bracket 100. The telescopic rod 210 extends and retracts, causing the connecting beam 230 to rise and fall. The support column 220 is provided with a through hole 229. The connecting beam 230 passes through the through hole 229 of the support column 220. The telescopic rod 210 extends and retracts, causing the connecting beam 230 and the support column 220 to rise and fall. The support position 260 is provided on the support column 220. The support column 220 rises and falls to adjust the height of the support position 260.

[0041] For example, such as Figure 7 As shown, the support position 260 is used to adapt the support column 220 to the support portion of the structure to be supported, such as a truss. The support position 260 is a groove structure provided on the support column 220, such as a rectangular groove, a circular groove, or a cross-shaped groove. In other embodiments, the support position 260 is a convex block structure provided on the top of the support column 220. This convex block structure is a polygonal prism block structure or a cylindrical block structure. The polygonal prism block structure is, for example, a triangular prism block structure, a square prism block structure, or a pentagonal prism block structure.

[0042] For example, the telescopic rod 210 includes, but is not limited to: hydraulic telescopic mechanism, pneumatic telescopic mechanism, electric actuator telescopic mechanism, threaded screw telescopic mechanism or linear motor, etc.

[0043] For example, such as Figure 6 As shown, one end of the connecting beam 230 supports a telescopic rod 210, and the other end of the connecting beam 230 supports a telescopic rod 210. In another embodiment, one end of the connecting beam 230 supports two telescopic rods 210, and the other end of the connecting beam 230 supports two telescopic rods 210. In yet another embodiment, one end of the connecting beam 230 supports two telescopic rods 210, and the other end of the connecting beam 230 supports three telescopic rods 210.

[0044] The lifting assembly 200, through the extension and retraction of the telescopic rod 210, drives the connecting beam 230 and the support column 220 to rise and fall, thereby adjusting the height of the support position 260. This height-adjustable design allows the height-adjustable temporary support device to adapt to structures with different height requirements, meet the support needs of different construction scenarios, and improve the flexibility and efficiency of construction.

[0045] To increase the load-bearing capacity of connecting beam 230, such as Figure 3 As shown, in one embodiment, the connecting beam 230 is a hollow beam with multiple reinforcing ribs 232 inside; the reinforcing ribs 232 are distributed at least at the connection points between the connecting beam 230 and the telescopic rod 210 and at the connection points between the connecting beam 230 and the support column 220. The reinforcing ribs 232 can improve the bending resistance of the connecting beam 230.

[0046] For example, the connecting beam 230 is configured as a quadrangular prism hollow beam, and the reinforcing rib 232 is configured as a rectangular plate. The reinforcing rib 232 is fixedly connected to the inner wall of the connecting beam 230, and the fixing method is, for example, welding, riveting or integral molding.

[0047] For example, such as Figure 3 As shown, a reinforcing rib 232 is provided on the inner wall of one end of the connecting beam 230 near the connection with the telescopic rod 210, and another reinforcing rib 232 is provided on the inner wall of the other end of the connecting beam 230 near the connection with the telescopic rod 210, to improve the bending resistance at both ends of the connecting beam 230; three reinforcing ribs 232 are provided at equal intervals on the inner wall of the connecting beam 230 near the connection with the support column 220, to improve the bending resistance in the middle part of the connecting beam 230. To further enhance the deformation resistance of the connecting beam 230, in another embodiment, two reinforcing ribs 232 are provided at equal intervals on the inner wall of one end of the connecting beam 230 near the connection with the telescopic rod 210, two reinforcing ribs 232 are provided at equal intervals on the inner wall of the other end of the connecting beam 230 near the connection with the telescopic rod 210, and three reinforcing ribs 232 are provided at intervals on the inner wall of the connecting beam 230 near the connection with the support column 220.

[0048] like Figure 8 and Figure 9 As shown, in one embodiment, the support 100 includes a lattice frame 110, a support platform 120, and a foundation beam 130.

[0049] The lattice frame 110 is vertically mounted on the ground or on the base 300. The top of the lattice frame 110 provides an installation foundation for the support platform 120.

[0050] The support platform 120 is fixedly installed on the top of the lattice frame 110, and the fixing method is, for example, welding, bolt connection or snap-fit; the support platform 120 provides a horizontal foundation for the installation of the foundation beam 130.

[0051] The foundation beam 130 is horizontally fixed to the support platform 120, and the fixing method is, for example, welding, bolting, or snap-fitting. The foundation beam 130 provides a horizontal mounting base for the telescopic pole 210.

[0052] like Figure 6 As shown, the telescopic rod 210 is fixedly installed on the foundation beam 130.

[0053] For example, such as Figure 10 As shown, the lattice frame 110 is formed by connecting multiple lattice units of equal height. Assuming each lattice unit is 2m high, and the height of the support platform 120 plus the foundation beam 130 is 0.5m, and the required support height for truss construction is 11m, then five lattice frames 110 are needed. These five lattice frames 110 are connected vertically to form a lattice frame 110 with a height of 10m. The entire support frame 100 has a height of 10.5 meters, and the telescopic rod 210 needs to lift the support column 220 to a height of 0.5m. If the required support height for truss construction is 13.5m, then six lattice frames 110 are needed. These six lattice frames 110 are connected vertically to form a lattice frame 110 with a height of 12m, and the entire support frame 100 has a height of 12.5 meters. The telescopic rod 210 needs to lift the support column 220 to a height of 1m.

[0054] like Figure 1 As shown, in one embodiment, the support platform 120 includes two cross-arranged transition beams 122 and a fixed beam 124 for connecting the two transition beams 122.

[0055] The two intersecting transition beams 122 are fixedly connected by welding or integral molding.

[0056] The fixed beam 124 is fixedly connected to the two transfer beams 122 by welding or integral molding.

[0057] For example, two fixed beams 124 are provided. However, other numbers of fixed beams 124 may also be provided, such as one, three, or four.

[0058] In one embodiment, the fixed beam 124 and the transfer beam 122 are made of I-beams.

[0059] like Figure 1 As shown, the foundation beam 130 extends from the intersection of the transfer beam 122 to both ends onto the fixed beam 124. The foundation beam 130 securely connects the transfer beam 122 and the fixed beam 124, and the securing method may be, for example, welding, bolting, or snap-fitting.

[0060] like Figures 4 to 6As shown, in one embodiment, the foundation beam 130 includes a hollow main beam 131 with a rectangular cross-section perpendicular to its length. An upper edge 132 and a lower edge 133 extend from the main beam along its width. The upper edge 132 provides more installation area for the telescopic rod 210, reducing the installation difficulty of the telescopic rod 210. Furthermore, the upper edge 132 can contact the support column 220, dispersing pressure and improving deformation resistance. The lower edge 133 increases the contact area between the foundation beam 130 and the transfer beam 122 and the fixed beam 124, dispersing pressure and improving deformation resistance.

[0061] To further enhance the deformation resistance of the upper edge 132 and the lower edge 133, at least one outer support plate 134 is provided between the upper edge 132 and the lower edge 133. Exemplarily, two outer support plates 134 are provided: one on one side of the upper edge 132 and the lower edge 133, and another on the other side of the upper edge 132 and the lower edge 133. Figure 1 As shown, in another embodiment, three outer support plates 134 are equidistantly arranged on one side of the upper edge 132 and the lower edge 133, and three outer support plates 134 are equidistantly arranged on the other side of the upper edge 132 and the lower edge 133.

[0062] For example, such as Figure 1 As shown, the upper edge 132, the hollow main beam 131 and the lower edge 133 define a U-shaped groove. The outer support plate 134 is configured as a rectangular plate structure that fits the U-shaped groove. The outer support plate 134 is fixedly connected to the upper edge 132, the outer wall of the hollow main beam 131 and the lower edge 133. The fixed connection method is, for example, welding or integral molding.

[0063] To further enhance the deformation resistance of the hollow main beam 131, such as Figure 1 As shown, at least one inner support plate 135 is provided inside the hollow main beam 131. Exemplarily, the hollow main beam 131 is configured as a rectangular hollow beam, and the inner support plate 135 is configured as a rectangular plate structure. The inner support plate 135 is fixedly connected to the inner wall of the hollow main beam 131, and the fixed connection method is, for example, welding or integral molding.

[0064] For example, an inner support plate 135 is provided inside the hollow main beam 131. In another embodiment, two inner support plates 135 are provided at intervals inside the hollow main beam 131, one inner support plate 135 is fixed in the inner wall of one end of the hollow main beam 131, and the other inner support plate 135 is fixed in the inner wall of the other end of the hollow main beam 131. In another embodiment, three inner support plates 135 are provided at equal intervals inside the hollow main beam 131, one inner support plate 135 is fixed in the inner wall of one end of the hollow main beam 131, one inner support plate 135 is fixed in the inner wall of the other end of the hollow main beam 131, and the other inner support plate 135 is fixed on the inner wall of the middle part of the hollow main beam 131.

[0065] like Figure 2 As shown, in one embodiment, the support column 220 has a cavity and a first reinforcing rib 222 and a second reinforcing rib 224 are disposed therein, and the first reinforcing rib 222 and the second reinforcing rib 224 are arranged crosswise.

[0066] For example, the first reinforcing rib 222 and the second reinforcing rib 224 are vertically arranged. The intersection angle between the first reinforcing rib 222 and the second reinforcing rib 224 is α, where α is a discrete value at a single point in the range of 45° to 90°.

[0067] In one embodiment, such as Figure 2 As shown, the support position 260 is provided with a groove structure, the first reinforcing rib 222 is provided with a U-shaped plate structure, and the second reinforcing rib 224 is provided with a rectangular plate structure. The first reinforcing rib 222 and the second reinforcing rib 224 are vertically fixedly connected. The fixed connection method is, for example, welding or integral molding. The first reinforcing rib 222 and the second reinforcing rib 224 are fixedly connected to the inner wall of the support column 220. The fixed connection method is, for example, welding or integral molding.

[0068] like Figure 5 or Figure 8 As shown, in one embodiment, the connecting beam 230 has two ends. A connecting plate 234 is provided on one end of the connecting beam 230 near the side wall of the telescopic rod 210, and a connecting plate 234 is provided on the other end of the connecting beam 230 near the side wall of the telescopic rod 210. The connecting plate 234 is fixedly installed on the end side wall of the connecting beam 230 near the telescopic rod 210, and the fixing method is, for example, welding, snap-fitting, or bolt connection.

[0069] The connecting plate 234 has a mating groove on the side wall near the telescopic rod 210 that is adapted to the telescopic end of the telescopic rod 210. The connecting beam 230 and the telescopic rod 210 are mated through the mating groove of the connecting plate 234.

[0070] The connecting plate 234 increases the bearing area of ​​the connecting beam 230, disperses the force, and improves the deformation resistance of the connecting beam 230.

[0071] like Figure 2 As shown, in one embodiment, a contact plate 226 and a triangular rib plate 228 are provided on one end of the support column 220 near the bracket 100.

[0072] For example, the contact plate 226 is fixedly connected to the bottom end of the support column 220, and the fixed connection method is, for example, welding or integral molding. The contact plate 226 makes the bottom end of the support column 220 form an inverted T-shaped structure, which increases the foundation area of ​​the support column 220 and the foundation beam 130.

[0073] For example, the triangular rib plate 228 is fixedly connected to the support column 220 and the contact plate 226, and the fixing method is, for example, welding or integral molding. The triangular rib plate 228 is used to support the contact plate 226 and increase the contact plate 226's resistance to deformation.

[0074] like Figure 6 As shown, in one embodiment, when the telescopic rod 210 extends, the support column 220 rises, thereby creating a gap between the support column 220 and the base beam 130 of the bracket 100. Figure 4 or Figure 9 As shown, the lifting assembly 200 also includes at least one pad 240, with at least one pad 240 provided at the gap. The pad 240 transmits the pressure on the support column 220 to the foundation beam 130 of the bracket 100. The number of pads 240 is provided depending on the size of the gap.

[0075] Unlike the technical solution of setting the pad 240 in the above embodiment, such as Figure 6 As shown, in one embodiment, when the telescopic rod 210 extends, the support column 220 rises, thereby creating a gap between the support column 220 and the base beam 130 of the bracket 100; as Figure 5 or Figure 8 As shown, the lifting assembly 200 also includes a step plate 250. The step plate 250 is provided at the gap and transmits the pressure on the support column 220 to the foundation beam 130 of the bracket 100.

[0076] The step plate 250 has a stepped surface. Depending on the size of the gap, the stepped surfaces of different heights on the step plate 250 cooperate with the support column 220, thereby transmitting the pressure at the support position 260 on the support column 220 to the foundation beam 130.

[0077] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
