Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an auxiliary support device for cantilevered I-beams. Background Technology

[0002] In traditional construction methods for new cantilevered I-beam scaffolding, the installation of these I-beams relies on a collaborative effort between workers. During installation, one worker manually supports the cantilevered end of the I-beam, while another worker secures the fixed end with high-strength bolts and nuts to connect it to the exterior wall. Due to human error, the manually supported cantilevered and fixed ends are not always on the same horizontal plane, making proper installation impossible. After the new I-beams are installed, the tie rods can only be installed once the preceding structure is complete and the concrete strength meets the requirements for tie rod installation. At this point, only the fixed end of the cantilevered I-beam is connected to the exterior wall via high-strength bolts, meaning only that end bears the load. In this traditional method, the cantilevered and fixed ends cannot be guaranteed to be on the same horizontal plane, resulting in wasted time and effort. Furthermore, if the tie rods are not installed, it can negatively impact the quality of the high-strength bolts and concrete. This not only leads to lengthy and inefficient leveling and support but also causes instability in the supported system, posing significant safety and quality risks to the construction project.

[0003] In view of this, it is necessary to design an auxiliary support device for cantilevered I-beams to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary support device for cantilevered I-beams that uses external scaffolding as a load-bearing point to provide support for cantilevered I-beams, can adapt to external scaffolding of different heights, ensures that the cantilevered I-beams are all on the same plane, and can keep the cantilevered I-beams fixed at all times, thus facilitating construction.

[0005] To achieve the above-mentioned objective, the present invention provides an auxiliary support device for cantilevered I-beams, comprising: Height adjustment mechanism; A fastening mechanism is provided at the bottom of the height adjustment mechanism to fix the height adjustment mechanism to the load-bearing point; A support platform is located on top of the height adjustment mechanism; At least two vertical lead screws are symmetrically arranged on the support platform via a reciprocating mechanism. Under the action of the reciprocating mechanism, the two symmetrically arranged vertical lead screws can move closer to or further away from each other, so that the vertical lead screws and the reciprocating mechanism together form a horizontal limiting structure that limits the horizontal orientation of the cantilevered I-beam. The vertical lead screws are rotatably connected to the reciprocating mechanism, and a clamping plate is also provided on the vertical lead screws, so that the vertical lead screws also serve as adjusting components for adjusting the distance between the clamping plate and the support platform. Thus, the vertical lead screws, clamping plates, and support platform together form a vertical limiting structure that limits the vertical orientation of the cantilevered I-beam.

[0006] As a further improvement of the present invention, the height adjustment mechanism includes a fixed part and a movable part that can move up and down relative to the fixed part under the action of a driving force.

[0007] As a further improvement of the present invention, the fastening mechanism includes a base and a fastener, one end of which is connected to the base via a rotating joint and the other end of which is connected to the base via a fastener, such that under the action of the fastener, a fixed space adapted to the external scaffold is formed between the fastener and the base.

[0008] As a further improvement of the present invention, the height adjustment mechanism is located in the middle of the bottom surface of the support platform.

[0009] As a further improvement of the present invention, the reciprocating moving mechanism includes a through groove disposed on the support platform, a bidirectional screw with one end rotatably connected to the side wall of the through groove and the other end passing through the other side wall of the through groove and connected to a driving member, and two sliders symmetrically disposed on the bidirectional screw along the center of the support platform.

[0010] As a further improvement of the present invention, the driving component is a rotary handle or a motor.

[0011] As a further improvement of the present invention, a transverse through hole communicating with the through groove is also provided on one side of the through groove corresponding to the vertical lead screw.

[0012] As a further improvement of the present invention, one end of the vertical lead screw extends into the horizontal through hole and is rotatably connected to the slider.

[0013] As a further improvement of the present invention, the transverse through hole is a through hole that runs vertically through the support platform.

[0014] As a further improvement of the present invention, one end of the vertical lead screw extends through a horizontal through hole to the bottom surface of the support platform and is also connected to a fixing member for keeping the vertical lead screw and the support platform relatively fixed.

[0015] The beneficial effects of this invention are: 1. This invention, by setting a fastening mechanism at the bottom of the height adjustment mechanism, can fix the height adjustment mechanism to the external scaffolding. The height adjustment mechanism can adapt to external scaffolding of different heights, and then use the support platform to support the cantilevered I-beams. This solves the problems of inconvenience and safety of manual support when installing new I-beams of the upper frame on external scaffolding, and the potential hazards to the quality of the external wall and high-strength bolts caused by the force on one end of the I-beam when no tie rod is installed.

[0016] 2. The vertical lead screw of the present invention, on the one hand, can be used as a limiting member, so that when the reciprocating moving mechanism adjusts the vertical lead screw to press against the side of the lower flange of the cantilever I-beam, the horizontal orientation of the cantilever I-beam is limited by the cooperation between the vertical lead screw and the reciprocating moving mechanism; on the other hand, the vertical lead screw, clamping plate and supporting platform can form a clamping structure to limit the vertical orientation of the cantilever I-beam, so that the cantilever I-beam always remains in a relatively fixed state during construction.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] like Figures 1-4 As shown, the present invention provides an auxiliary support device for a cantilevered I-beam, comprising: Height adjustment mechanism; A fastening mechanism is provided at the bottom of the height adjustment mechanism to fix the height adjustment mechanism to the load-bearing point; Support platform 30 is disposed on top of the height adjustment mechanism; At least two vertical lead screws 51 are symmetrically arranged on the support platform 30 via a reciprocating mechanism. Under the action of the reciprocating mechanism, the two symmetrically arranged vertical lead screws 51 can move closer or further apart from each other, so that the vertical lead screws 51 and the reciprocating mechanism together form a horizontal limiting structure that limits the horizontal orientation of the cantilevered I-beam 62. The vertical lead screws 51 are rotatably connected to the reciprocating mechanism, and a clamping plate 53 is also provided on the vertical lead screws 51, so that the vertical lead screws 51 also serve as adjusting components for adjusting the distance between the clamping plate 53 and the support platform 30. Thus, the vertical lead screws 51, the clamping plate 53, and the support platform 30 together form a vertical limiting structure that limits the vertical orientation of the cantilevered I-beam 62.

[0026] Specifically, the height adjustment mechanism includes a fixed part and a movable part that can move up and down relative to the fixed part under the action of driving force. For example, the fixed part is a support tube 11 that is hollow inside and open at the top. The hollow part of the support tube 11 is provided with internal threads. The movable part is a threaded tube 12 that extends from the top of the support tube 11 into the support tube 11 and is threadedly connected to the support tube 11. The top of the support tube 11 is also connected to a rotating nut 13 through a bearing. The threaded tube 12 is also threadedly connected to the rotating nut 13. The rotating nut 13 acts as a driving member. When an external force drives the rotating nut 13 to rotate, the rotating nut 13 drives the threaded tube 12 to rotate, thereby changing the support length of the overall structure formed by the support tube 11 and the threaded tube 12.

[0027] The top end of the threaded tube 12 is connected to the support platform 30 through a bearing, so that the horizontal orientation of the support platform 30 remains stable when the threaded tube 12 rotates.

[0028] In other examples, the height adjustment mechanism can also be configured as a hydraulic telescopic rod.

[0029] Specifically, the fastening mechanism includes a base support 21 and a fastener 22 whose left end is connected to the base support 21 via a rotating joint and whose right end is connected to the base support 21 via a fastener. This creates a fixed space between the fastener 22 and the base support 21 that is compatible with the external scaffolding 61, under the action of the fastener. For example, the base support 21 is located at the bottom of the support tube 11 and has an arc-shaped concave area. The fastener 22 is correspondingly arc-shaped, so that when the right end of the fastener 22 is fixed to the base support 21 via a fastener, a fixed space is formed between the fastener 22 and the base support 21 that is compatible with the external scaffolding 61, thereby fixing the height adjustment mechanism to the external scaffolding 61.

[0030] The base 21 has a first screw hole on its right end, and the fastener 22 has a corresponding second screw hole. The fastener is a fastening bolt 23. By passing the fastening bolt 23 through the first screw hole and the second screw hole in sequence, and adjusting the length of the fastening bolt 23 in the first screw hole, the size of the fixing space can be adjusted according to the diameter of the outer scaffold 61.

[0031] For example, the height adjustment mechanism is located at the center of the bottom surface of the support platform 30 to provide stable support for the support platform 30.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, there are two vertical lead screws 51; the reciprocating movement mechanism includes a through groove 41 set on the support platform 30, a bidirectional screw 42 whose left end is connected to the side wall of the through groove 41 by a bearing, and whose right end passes through the other side wall of the through groove 41 and is connected to a driving component, and two sliders 43 symmetrically arranged on the bidirectional screw 42 along the center of the support platform 30.

[0033] For example, the through groove 41 is built into the support platform 30 and is parallel to the length direction of the support platform 30. The right end of the bidirectional screw 42 is also connected to the side wall of the through groove 41 through a bearing, so that under the drive of the drive component, the bidirectional screw 42 rotates and drives the two sliders 43 to move closer or further apart.

[0034] The driving component is either a rotary handle 44 or a motor. In this example, the driving component is a rotary handle 44.

[0035] For example, on one side of the through groove 41, corresponding to the vertical lead screw, there are two horizontal through holes 52 that communicate with the through groove 41. The horizontal through holes 52 are also arranged along the length direction of the support platform 30. One end of the vertical lead screw 51 extends into the horizontal through hole 52 and is rotatably connected to the slider 43.

[0036] In this example, the horizontal through hole 52 is a through hole that passes through the support platform 30 from top to bottom; the slider 43 is provided with a mounting hole with a diameter larger than that of the vertical lead screw 51. One end of the vertical lead screw 51 extends into the horizontal through hole 52, passes through the mounting hole, and is connected to the slider 43 through a bearing, so that the vertical lead screw 51 can rotate relative to the slider 43 under the action of external force.

[0037] The portion of the vertical lead screw 51 extending through the transverse through hole 52 to the bottom surface of the support platform 30 is also connected to a fastener for keeping the vertical lead screw 51 and the support platform 30 relatively fixed. For example, the fastener is a fixing nut 54 threadedly connected to the vertical lead screw 51. The outer diameter of the fixing nut 54 is larger than the diameter of the transverse through hole 52, so that when the fixing nut 54 is rotated to its top pressing against the bottom surface of the support platform 30, the vertical lead screw 51 and the support platform 30 are kept relatively fixed.

[0038] A vertical lead screw 51 is located in the middle of the support platform 30 along the width direction of the support platform 30.

[0039] The vertical lead screw 51 of this invention serves two purposes. First, it acts as a limiting element, allowing the reciprocating mechanism to adjust the vertical lead screw 51 to press against the side of the lower flange of the cantilevered I-beam 62, thereby limiting the horizontal orientation of the cantilevered I-beam 62 through the cooperation of the vertical lead screw 51 and the reciprocating mechanism. Second, it enables the vertical lead screw 51 to form a clamping structure with the clamping plate 53 and the supporting platform 30, limiting the vertical orientation of the cantilevered I-beam 62, thus ensuring that the cantilevered I-beam 62 remains relatively fixed during construction.

[0040] For example, vertical plates 31 are also provided on both sides of the support platform 30.

[0041] In the initial state, the two sliders 43 are located at both ends of the bidirectional screw 42, so that the distance between the two vertical screws 51 is maximized, and the clamping plate 53 is located on the upper part of the vertical screw 51, so that the distance between the clamping plate 53 and the support platform 30 is greater than the thickness of the lower flange of the cantilever I-beam 62; the fastening mechanism is fixed on the external scaffold 61 at the predetermined position, and the position of the threaded pipe 12 relative to the support pipe 11 is adjusted by rotating the nut 13 to adjust the support length of the height adjustment mechanism, so that when the cantilever end of the cantilever I-beam 62 is on the support platform 30, the entire cantilever I-beam 62 is on the same horizontal plane; Place the cantilevered I-beam 62 on the support platform 30, drive the rotating handle 44 to move the two sliders 43 towards each other until the two vertical screw rods 51 move along the transverse through holes 52 and abut against both sides of the cantilevered I-beam 62, thus completing the horizontal fixation of the cantilevered I-beam 62; then, rotate the two vertical screw rods 51 so that the clamping plates 53 on the two vertical screw rods 51 move towards the support platform 30 until the clamping plates 53 abut against the top surface of the lower flange of the cantilevered I-beam 62, and fix the vertical screw rods 51 to the support platform 30 by fixing the nuts 54, thus completing the vertical fixation of the cantilevered I-beam 62.

[0042] Specifically, by fixing the height adjustment mechanism at a predetermined position on the external scaffolding 61, the center of the support platform 30 is the same as the center of the cantilevered I-beam 62, which means that the horizontal orientation of the cantilevered I-beam 62 can be quickly fixed by rotating the bidirectional screw 42.

[0043] This invention adapts to external scaffolding 61 of different heights through a height adjustment mechanism, and uses vertical lead screws 51, reciprocating movement mechanism, vertical lead screws 51, clamping plates 53, and support platforms 30 to fix the horizontal and vertical positions of the cantilevered I-beams 62. The operation is simple and can quickly fix the cantilevered I-beams 62 and ensure the fixing effect. At the same time, it can also adapt to different models of cantilevered I-beams 62. It can solve the problem that workers need to support the cantilevered I-beams 62 with force on the external scaffolding during installation, which is inconvenient and unsafe. It can also solve the problem that when the tie rod is not installed, the force on one end of the cantilevered I-beams 62 may cause hidden dangers to the quality of the external wall and the high-strength tie rods.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
