Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and in particular to an adjustable construction engineering support structure. Background Art

[0002] At present, the building support structure is a structural system used to support and disperse loads in buildings. It is an important part of the building and can ensure the stability, strength and safety of the building. The building support structure includes foundations, columns, walls, beams, floor slabs, roofs, etc. The foundation is the load-bearing foundation of the building, bearing the weight and load of the building and transferring it to the foundation. The column is the most common supporting structure in the building, bearing the weight of the floors and roofs and transferring it to the foundation. The wall is an important structure that bears lateral loads and seismic resistance, and can ensure the stability of the building. Beams and floor slabs are structures used to disperse loads in buildings, which can evenly distribute the load to the supporting structure. The roof is the top structure of the building, which withstands the influence of the external environment and protects the internal structure of the building.

[0003] In the prior art, the authorization announcement number is: CN214329879U, an adjustable construction engineering formwork support device, which includes a base, a bracket, a support frame and a connecting plate, ensuring the stability and reliability of the device, and an adjustment structure is provided on the surface of the support frame at the bottom end of the connecting plate, which can easily adjust the height of the device to adapt to different construction requirements. At the same time, the reinforcement structure provided inside the support frame further improves the bearing capacity of the device. The reinforcement structure includes transverse reinforcement ribs, vertical reinforcement ribs and a ceramic particle layer. The ceramic particle layer is filled inside the support frame to enhance the durability and compressive resistance of the device, while the transverse reinforcement ribs and vertical reinforcement ribs are further enhanced by a precise winding process to enhance the structural strength of the device, ensuring that the device can remain stable even in harsh construction environments. The adsorption structure fixedly connected to the top of the connecting plate not only improves the adhesion between the device and the formwork, but also realizes the limiting function of the device, effectively preventing the device from shifting or sliding during use;

[0004] However, after the material is raised, the center of gravity of this patent rises accordingly, and the bottom support is insufficient, making it easy for the material to tilt and overturn, posing a safety hazard. In addition, this patent cannot adjust the balance and has poor stability in use.

[0005] In the prior art, the patent for a construction engineering reinforcement support structure with the authorization announcement number CN220184728U includes a clamping mechanism, a telescopic mechanism, and a lifting mechanism, which realizes efficient and safe support for beams. The clamping mechanism and the telescopic mechanism are carefully configured on the lifting mechanism to ensure the convenience and stability of operation. The unique lifting and adjustable design allows the clamping mechanism to easily adapt to beams of different heights, which not only improves the support strength but also ensures the safety of the operation. The introduction of the telescopic mechanism allows the width of the support reinforcement to be flexibly adjusted to perfectly cope with various beam widths. This design greatly simplifies the operation process and avoids time-consuming and labor-intensive manual adjustment. By adopting a hydraulic mechanism for adjustment, it not only improves work efficiency but also greatly reduces operational risks, providing users with unprecedented safety and convenience.

[0006] However, this patent also fails to provide sufficient support force after the center of gravity is raised, making it prone to tilting and overturning, posing a safety hazard. Utility Model Content

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0028] Example 1

[0029] like Figures 1 to 6As shown, this embodiment proposes an adjustable construction engineering support structure, including a base 1, a scissor rod 6 is rotatably installed on the base 1, a support plate 21 is rotatably installed on the scissor rod 6, two symmetrically arranged cross bars 7 are rotatably installed inside the scissor rod 6, and wheels are fixedly sleeved at both ends of the two cross bars 7, two of which are located inside the base 1, and the other two wheels are located inside the support plate 21, four symmetrically arranged short bars 12 are welded on the base 1, and rotating wheels 13 are rotatably installed on the outer circumferences of the four short bars 12, a reinforcement device is provided inside the base 1, and the reinforcement device includes a rack plate 8, the cross bar 7 is rotatably installed inside the rack plate 8, the inside of the base 1 is fixedly connected to a guide plate 9 by screws, and the guide plate 9 is slidably assembled inside the rack plate 8, a round rod 10 is rotatably installed inside the base 1, and a gear 11 and a driving wheel are fixedly sleeved on the outer circumferences of the round rod 10. 22. The bottom of the base 1 is fixedly connected to a fixed block 16 by screws, and a threaded sleeve 17 is rotatably installed inside the fixed block 16. The internal threads of the threaded sleeve 17 are installed with two symmetrically arranged linkage screws 18. The bottom of the base 1 is fixedly connected to two symmetrically arranged sliding sleeves 14 by screws. The interiors of the two sliding sleeves 14 are slidably equipped with sliding blocks 15. One end of the two linkage screws 18 is welded to one side of the two sliding blocks 15 respectively. A driven wheel 19 is fixed on the outer circumference of the threaded sleeve 17. Through the arrangement of the linkage screw 18, the sliding plate and other structures, the material is placed on the top of the support plate 21, and the cylinder on the scissor rod 6 is started. The scissor rod 6 is extended to drive the support plate 21 to rise. At the same time, the threaded sleeve 17 rotates to drive the linkage screw 18 to move to both sides, and the linkage screw 18 drives the sliding plate to move to both sides and open, so as to prevent the scissor rod 6 from tilting and overturning after the center of gravity rises, thereby improving safety.

[0030] like Figures 1 to 6 As shown, a belt 20 is sleeved on the outer circumference of the driving wheel 22 and the driven wheel 19. A rotating groove is opened inside the base 1, and the round rod 10 is rotatably installed inside the rotating groove.

[0031] like Figures 1 to 3 As shown, two symmetrically arranged transverse grooves are provided inside the scissor-type fork rod 6, and two transverse rods 7 are rotatably installed inside the two transverse grooves respectively.

[0032] like Figure 4 As shown, the rack plate 8 and the gear 11 are engaged with each other, a long slot is provided inside the rack plate 8, and the guide plate 9 is slidably connected inside the long slot.

[0033] like Figure 5 As shown, a circular groove is provided inside the fixing block 16, and the threaded sleeve 17 is rotatably installed inside the circular groove.

[0034] like Figure 5 As shown, a transverse thread groove is provided inside the threaded sleeve 17, and the linkage screw 18 is threadedly connected inside the transverse thread groove.

[0035] In this embodiment, the material to be transported is first gently placed on the top of the support plate 21, and then the cylinder on the scissor rod 6 is started. The driving force of the cylinder will extend the scissor rod 6, thereby driving the support plate 21 to rise steadily. At the same time, the cross bar 7 drives the rack plate 8 to move, and the rack plate 8 drives the round rod 10 to rotate through the gear 11, and the round rod 10 drives the driving wheel 22 to rotate. The driving wheel 22 drives the driven wheel 19 to rotate through the belt 20, and the driven wheel 19 drives the threaded sleeve 17 to rotate. This action will drive the linkage screw 18 to move to both sides. The movement of the linkage screw 18 further drives the sliding plate to expand to both sides, effectively preventing the scissor rod 6 from tilting and overturning due to loss of balance after the center of gravity is raised. Such a design not only ensures the safety of the material handling process, but also greatly improves work efficiency.

[0036] Example 2

[0037] like Figures 1 to 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that four symmetrically arranged vertical blocks 2 are fixedly connected to the base 1 by screws, and the interiors of the four vertical blocks 2 are all threadedly installed with lifting screws 3, and the bottom of the lifting screw 3 is welded with an anti-sliding block 4.

[0038] like Figures 1 to 3 As shown, a vertical thread groove is provided inside the vertical block 2, and the lifting screw 3 is threadedly connected inside the vertical thread groove.

[0039] In this embodiment, since the ground at the construction site is often uneven, the base 1 cannot remain level and is prone to tilting and overturning when pushing materials. The lifting screw 3 is rotated according to the flatness of the ground, and the distance between the anti-sliding block 4 and the base 1 is adjusted. When the base 1 is adjusted to a horizontal state, the lifting screw 3 is stopped, so that the material lifting is more stable, and the anti-sliding block 4 can increase the friction between it and the ground.

[0040] In addition, four symmetrically arranged fluorescent stickers 5 are bonded to the base 1. When lifting materials at night, light shining on the fluorescent stickers 5 will reflect light, making the base 1 more eye-catching and improving safety.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
