Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a formwork support device for building engineering. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Buildings" specifically refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, living, learning, and public activities. Formwork support devices are required during the construction process.

[0003] For example, application number CN202420273840.4 discloses a formwork support device for construction engineering, including a base. A motor is fixedly connected to the top of the base, and a reciprocating screw is fixedly sleeved on the output shaft of the motor. A drive ring is threaded onto the outer wall of the reciprocating screw, and two open rectangular blocks are fixedly connected to the top of the drive ring. Two limiting rods penetrating the two open rectangular blocks are fixedly connected to the top of the base. Multiple triangular support frames are arranged in a circular array on the top of the drive ring. This utility model is simple to use. When the motor is started, the height of multiple support plates can be adjusted. Magnetic plates are set on the support plates to attract metal construction engineering molds and prevent them from moving. The use of multiple support plates to support the construction engineering mold disperses the force and increases the support force on the construction engineering mold. The triangular support frames adopt a triangular structure design to support other components and have stronger stability.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that using only threaded rods for support can easily cause the threaded rod to tilt to one side due to insufficient support points, resulting in instability of the center of gravity, which in turn can lead to the tilting and collapse of the device. Furthermore, the formwork falling from the threaded rod poses a safety hazard to workers in the area. However, during use, the motor is directly connected to the support device and the base, thus the motor is sandwiched between the two. Consequently, the motor directly bears a large amount of pressure from the support device and the formwork, making it prone to deformation and damage. At the same time, the motor is exposed to the elements, and the construction environment often contains concrete slurry, which can easily penetrate the motor, causing short circuits or wear and shortening its service life.

It solves the problem that the motor is directly connected to the support device and the base, so the motor is sandwiched between the two and directly bears a lot of pressure from the support device and the formwork, making the motor prone to deformation and damage. At the same time, the motor is exposed to the outside, and the construction environment often contains concrete slurry, which can easily penetrate the motor and cause short circuits or wear, shortening its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a formwork support device for construction engineering, comprising a support device, the support device including a base, a motor, a support frame, a screw, a limiting block, and a limiting rod.

[0029] Example 1

[0030] Reference Figure 1-3This is the first embodiment of the present invention, providing a formwork support device 1 for construction engineering, including a support device 1. The support device 1 includes a base 101, a motor 102, a support frame 103, a screw 104, a limiting block 105, and a limiting rod 106. The motor 102 is fixedly installed on the left side of the top of the base 101. The support frame 103 is disposed on the top of the base 101. The surface of the screw 104 is threadedly connected to the inner wall of the support frame 103. The limiting block 105 is fixedly connected to the four sides of the bottom surface of the support frame 103. The surface of the limiting rod 106 is slidably connected to the inner wall of the limiting block 105, and the bottom of the limiting rod 106 is fixedly connected to the top of the base 101.

[0031] The reversing drive assembly 2 includes a first bevel tooth 201, which is fixedly installed at the output end of the motor 102. The top of the first bevel tooth 201 is meshed with a second bevel tooth 202, and the top of the second bevel tooth 202 is fixedly connected to the bottom of the screw 104.

[0032] Support component 3 is fixedly installed at the bottom of the second conical tooth 202;

[0033] Anti-upward displacement component 4 is provided at the bottom of the surface of screw 104;

[0034] The protective component 5 is disposed on the top of the base 101. The support component 3 includes an extension column 301, which is fixedly installed at the bottom of the second conical tooth 202. A pressure bearing 302 is fixedly connected to the bottom of the extension column 301, and the bottom of the pressure bearing 302 is fixedly connected to the top of the base 101. The anti-upward displacement component 4 includes an annular groove 401, which is formed at the bottom of the surface of the screw 104. L-shaped plates 402 are fixedly connected to both sides of the top of the base 101, and one end of the L-shaped plate 402 is slidably connected to the inner wall of the annular groove 401. U-shaped handles 8 are fixedly connected to both sides of the outer sides of the first half-cover 501 and the second half-cover 502, and the U-shaped handles 8 are used to move the first half-cover 501 and the second half-cover 502.

[0035] Specifically, the reversing drive assembly 2 is used to indirectly drive the screw 104 to rotate via the motor 102. Then, the support assembly 3 and the anti-upward displacement assembly 4 stabilize the transmission between the drive assembly and the screw 104, ensuring that the support frame 103 rises stably through the rotation of the screw 104.

[0036] Furthermore, when the screw 104 needs to rotate to drive the support frame 103 to rise and provide support for the template, the motor 102 drives the first bevel gear 201 to rotate, meshing and driving the second bevel gear 202 and the screw 104 to rotate. The support frame 103 then moves vertically up and down along the trajectory of the screw 104, with the cooperation of the limit rod 106. Then, as the screw 104 rotates, the L-shaped plate slides in the annular groove 401, forming an axial constraint to prevent the screw 104 from moving upward and causing unstable meshing between the first bevel gear 201 and the second bevel gear 202. At the same time, the pressure of the support frame 103 and the template is transmitted to the extension column 301 through the second bevel gear 202, and then to the base 101 through the pressure bearing 302. Thus, the motor 102 only needs to provide rotational torque and does not need to bear the support weight, thereby avoiding failure of the motor 102 due to deformation under pressure.

[0037] Example 2

[0038] The second embodiment of this utility model provides a formwork support device 1 for building engineering. The protective component 5 includes a first half-cover 501, the bottom of which is in contact with the left side of the top of the base 101, and a second half-cover 502 in contact with the right side of the first half-cover 501. The bottom of the second half-cover 502 is in contact with the right side of the top of the base 101. The surface of the screw 104 is in contact with the inner wall of the first half-cover 501 and the second half-cover 502. The motor 102, the first bevel gear 201, and the second bevel gear 202 are all located inside the first half-cover 501 and the second half-cover 502. Insertion components 6 are provided on both sides of the bottom inner side of the first half-cover 501 and the second half-cover 502. Slanted heat dissipation grooves 7 are provided on the front and back of the first half-cover 501 and the second half-cover 502. Several slanted heat dissipation grooves 7 are provided and are evenly distributed.

[0039] Specifically, by using the plug-in component 6, the protective component 5 can be quickly and easily installed onto the base 101, covering the motor 102 with the first bevel gear 201 and the second bevel gear 202, thereby preventing concrete slurry from entering and reducing the risk of short circuits and wear.

[0040] Furthermore, before using the motor 102, the first half-cover 501 and the second half-cover 502 are lifted using the U-shaped handle 8, and the grooves 601 at the bottom of both are aligned with the fixing rods 602 on the base 101 one by one, and then inserted to complete the connection with the base 101. Therefore, the plug-in connection method facilitates the disassembly of the first half-cover 501 and the second half-cover 502, so as to facilitate the daily maintenance of the first bevel gear 201, the second bevel gear 202 and the motor 102. Finally, the closure of the first half-cover 501 and the second half-cover 502 forms a protective space to prevent concrete slurry from entering the motor 102 and the first bevel gear 201 and the second bevel gear 202, thereby reducing the risk of short circuits and wear. Then, the inclined heat dissipation groove 7 can be used to smoothly dissipate the heat generated by the motor 102 during operation into the first half-cover 501 and the second half-cover 502, thus avoiding heat accumulation that affects the stable operation of the motor 102.

[0041] Working principle:

[0042] When support is needed for formwork in a construction project, the first half-cover 501 and the second half-cover 502 are lifted using the U-shaped handle 8. The grooves 601 at the bottom of both are aligned with the fixing rods 602 on the base 101, and then inserted to complete the connection with the base 101. The closure of the first half-cover 501 and the second half-cover 502 forms a protective space, preventing concrete slurry from entering the motor 102 and the first and second bevel gears 201 and 202, reducing the risk of short circuits in the motor 102 and wear on the first and second bevel gears 201 and 202. Then, the inclined heat dissipation grooves 7 are used to allow the heat generated by the motor 102 during operation to be smoothly discharged from the first half-cover 501 and the second half-cover 502, preventing heat accumulation from affecting the stable operation of the motor 102. The motor 102 can then be started, driving the first bevel gear 201 to rotate, which in turn drives the second bevel gear 202 and the screw 104 to rotate. As the screw 104 rotates, the support frame 103 moves vertically up and down along the trajectory of the screw 104, with the cooperation of the limiting rod 106. Then, as the screw 104 rotates, the L-shaped plate slides in the annular groove 401, forming an axial constraint to prevent the screw 104 from moving upward and causing unstable meshing between the first bevel tooth 201 and the second bevel tooth 202. At the same time, the pressure of the support frame 103 and the template is transmitted to the extension column 301 through the second bevel tooth 202, and then to the base 101 through the pressure bearing 302. Thus, the motor 102 only needs to provide rotational torque and does not need to bear the supporting weight, thereby avoiding failure caused by the deformation of the motor 102 under pressure. Finally, the support frame 103 contacts the construction template and provides support for it. This prevents the motor 102 from directly bearing a large amount of pressure from the support device 1 and the template, which could easily cause deformation and damage to the motor 102. This provides the advantage of auxiliary protection for the motor 102.

[0043] In summary, the formwork support device 1 for construction engineering, by setting up a reversing drive component 2 and a support component 3, allows the reversing drive component 2 to move stably under the support of the support component 3 when the motor 102 starts, driving the screw 104 to rotate. This enables the motor 102 to drive the screw 104 to rotate without being compressed. This solves the problem of the motor being directly connected to the support device and the base, thus sandwiching the motor between the two and subjecting it to a large amount of pressure from the support device and the formwork, making the motor prone to deformation and damage. At the same time, the motor is exposed to the outside, and the construction environment often contains concrete slurry, which can easily penetrate the motor and cause short circuits or wear, shortening its service life.
