Description

Technical Field

[0001] The utility model relates to the technical field of temporary support for basement concrete, in particular to a temporary support device for basement concrete with a super large area. Background Art

[0002] A basement is a room whose floor is lower than the outdoor ground level by more than half of the room's net height. Multi-story and high-rise buildings require a deeper foundation. To utilize this height, a basement is built under the bottom floor of the building. This can increase the usable area and save the backfill in the center of the house, which is relatively economical. Building a basement below the bottom floor of a house can improve the efficiency of building land. Some high-rise buildings have a very deep burial depth. Making full use of this depth to build a basement has excellent economic and practical effects. Basements are divided into ordinary basements and air-raid basements according to their functions; according to structural materials, there are brick wall structure and concrete structure basements; according to structural forms, there are full basements and semi-basements.

[0003] Publication No. "CN217175695U" provides a temporary horizontal concrete support device, comprising: a mounting frame for mounting various parts; a support platform for supporting horizontal concrete; the support platform is arranged on the mounting frame; a support rod for supporting the support platform; the first end of the support rod is connected to the mounting frame and the second end is connected to the support platform. The temporary horizontal concrete support device provided by the present application improves the safety of support removal and reduces the cost of support removal.

[0004] However, the above device still has the following problems during implementation:

[0005] During the construction of the basement, there will be many temporary concrete buildings on the basement ceiling, which need to be cut and removed after the basement is completed. In order to ensure the safety of concrete cutting and removal, some temporary support devices are usually used to support the concrete, thereby improving the effect of cutting and removal. However, in some ultra-large basement environments, the height of the temporary concrete on the ceiling is not uniform. If the support height of the temporary support device cannot match the height of the temporary concrete, it will not be able to play a supporting effect. Utility Model Content

[0009] The stabilizing mechanism is fixedly arranged on the transmission mechanism, and when the transmission mechanism adjusts the height of the support plate, the stabilizing mechanism can improve the stability of the support by expanding the contact area between the base and the ground.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. This utility model takes into account that in some ultra-large basement environments, the height of temporary concrete on the ceiling is not uniform. If the support height of the temporary support device cannot match the height of the temporary concrete, it cannot play a supporting effect. Therefore, by setting a transmission mechanism, the temporary support device can be moved to the bottom of the temporary concrete that needs to be supported, and then the motor is started. The motor drives the first screw rod to rotate around the first bearing seat. When the first screw rod rotates, it will drive the connecting block and the support rod to move upward under the restriction of the sleeve. The support rod will drive the support plate to move upward until the support plate contacts the temporary concrete that needs to be supported, and the support can be completed;

[0018] 2. The utility model takes into account that after the height of the support plate is raised, the center of gravity of the temporary support device moves up, the stability is reduced, and the support effect is also affected. Therefore, by setting a stabilizing mechanism, the first bevel gear can be driven to rotate while the motor rotates, and the first bevel gear is meshed with the second bevel gear, so the second bevel gear and the second screw rod can be driven to rotate around the second bearing seat. When the second screw rod rotates, the push block and the push rod can be driven to move. Figure 2 As shown, the counterweight block is opened to both sides, thereby increasing the contact area with the ground and improving the stability of the temporary support device;

[0019] In the present invention, by setting a transmission mechanism, the temporary support device can be moved to the bottom of the temporary concrete that needs to be supported, and then the motor is started. The motor drives the first screw rod to rotate around the first bearing seat. While the first screw rod rotates, it drives the connecting block and the support rod to move upward under the restriction of the sleeve, and the support rod drives the support plate to move upward until the support plate contacts the temporary concrete that needs to be supported, and the support can be completed. At the same time, the stabilizing mechanism can avoid the situation where the center of gravity of the temporary support device moves up and the stability is reduced after the height of the support plate is increased, which solves the problem that the height of the temporary concrete on the ceiling is not uniform in some ultra-large basement environments. If the support height of the temporary support device cannot match the height of the temporary concrete, the support effect cannot be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A temporary support device for concrete of a large-area basement, comprising a base 1 and a support plate 2, wherein the support plate 2 is located on the top of the base 1, two sleeves 3 are fixedly connected to the top of the base 1, support rods 4 are inserted into the sleeves 3, and the top of the support rods 4 is fixedly connected to the bottom of the support plate 2, a transmission groove 5 is provided inside the base 1, and a transmission mechanism for adjusting the height of the support plate 2 is provided inside the transmission groove 5;

[0031] The stabilizing mechanism is fixedly arranged on the transmission mechanism, and can improve the stability of the support by expanding the contact area between the base 1 and the ground while the transmission mechanism adjusts the height of the support plate 2.

[0032] One implementation of the first embodiment is as follows: the transmission mechanism includes a motor 6 fixedly installed inside the transmission slot 5, the output end of the motor 6 is fixedly connected to a first screw rod 7, the top of the first screw rod 7 penetrates through the top of the base 1, the surface of the first screw rod 7 is transmission-connected to a connecting block 8, and the two sides of the connecting block 8 are respectively fixedly connected to one side of the two support rods 4;

[0033] This embodiment takes into account that in some ultra-large basement environments, the height of temporary concrete at the ceiling is not uniform. If the support height of the temporary support device cannot match the height of the temporary concrete, the support effect cannot be achieved. Therefore, by setting a transmission mechanism, the temporary support device can be moved to the bottom of the temporary concrete that needs to be supported, and then the motor 6 is started. The motor 6 drives the first screw rod 7 to rotate around the first bearing seat 18. When the first screw rod 7 rotates, it will drive the connecting block 8 and the support rod 4 to move upward under the restriction of the sleeve 3. The support rod 4 will drive the support plate 2 to move upward until the support plate 2 contacts the temporary concrete that needs to be supported, and the support can be completed;

[0034] The invention solves the problem that in some ultra-large basement environments, the height of temporary concrete at the ceiling is not uniform. If the support height of the temporary support device cannot match the height of the temporary concrete, the support effect cannot be achieved.

[0035] Preferably, a first support frame 17 is sleeved on the surface of the first screw rod 7, the bottom of the first support frame 17 is fixedly connected to the top of the base 1, and a first bearing seat 18 is provided on the top of the first support frame 17, and is rotatably connected to the surface of the first screw rod 7 through the first bearing seat 18;

[0036] In this embodiment, by providing the first support frame 17 and the first bearing seat 18, the first support frame 17 and the first bearing can support the first screw rod 7, thereby preventing the first screw rod 7 from being unstable during rotation due to its own excessive height, and improving the smoothness of the first screw rod 7 during rotation;

[0037] It should be noted that the motor 6 rotates in the opposite direction and cooperates with the transmission mechanism to move the support plate 2 downward, which is opposite to the above steps. The screw transmission method is well known to those skilled in the art and will not be described in detail.

[0038] Embodiment 2:

[0039] On the basis of the first embodiment, the transmission mechanism in the present embodiment can adjust the height of the support plate 2 so that it can support temporary concrete of different heights. However, considering that after the height of the support plate 2 is raised, the center of gravity of the temporary support device moves up, the stability is reduced, and the support effect is also affected. The stabilizing mechanism in the present application includes a first bevel gear 9 fixedly connected to the surface of the output end of the motor 6, and the first bevel gear 9 is meshingly connected to the second bevel gear 10 on both sides, and the second bevel gear 10 is fixedly connected to one side of the second bevel gear 10. The surface of the second screw rod 11 is transmission-connected to a push block 12, and one side of the push block 12 is fixedly connected to two push rods 13. Counterweight blocks 14 are provided on both sides of the base 1, and one end of the push rod 13 passes through one side of the base 1 and is fixedly connected to one side of the counterweight block 14.

[0040] In this embodiment, it is considered that after the height of the support plate 2 is raised, the center of gravity of the temporary support device moves up, the stability is reduced, and the support effect is also affected. Therefore, by setting a stabilizing mechanism, the first bevel gear 9 can be driven to rotate while the motor 6 rotates. The first bevel gear 9 is meshed with the second bevel gear 10, so the second bevel gear 10 and the second screw rod 11 can be driven to rotate around the second bearing seat 20. When the second screw rod 11 rotates, the push block 12 and the push rod 13 can be driven to move. Figure 2 As shown, the counterweight block 14 is opened to both sides, thereby increasing the contact area with the ground and improving the stability of the temporary support device.

[0041] Preferably, the ratio between the first bevel gear 9 and the second bevel gear 10 is 1:2.5;

[0042] In this embodiment, the ratio between the first bevel gear 9 and the second bevel gear 10 is set to 1:2.5. When the first bevel gear 9 rotates 2.5 circles, the second bevel gear 10 will be driven to rotate one circle, thereby reducing the adjustment range of the counterweight 14, avoiding excessive adjustment spacing, and causing the temporary support device to be unstable during the adjustment process.

[0043] Preferably, guide blocks 15 are fixedly connected to both sides of the push block 12, and the inner wall of the transmission groove 5 is provided with a guide groove 16 used in conjunction with the guide block 15;

[0044] This embodiment sets the guide block 15 and the guide groove 16 to limit the movement of the push block 12 and other structures during the rotation of the second screw rod 11, so that the push block 12 and other structures can only slide along the trajectory of the guide block 15 and the guide groove 16, thereby improving the stability during the movement.

[0045] Preferably, a second support frame 19 is sleeved on the surface of the second screw rod 11, the bottom of the second support frame 19 is fixedly connected to the inner wall of the transmission groove 5, a second bearing seat 20 is provided on one side of the second support frame 19, and the second bearing seat 20 is rotatably connected to one side of the second bevel gear 10;

[0046] In this embodiment, by providing the second support frame 19 and the second bearing seat 20, the position of the second bevel gear 10 can be limited, so that the second bevel gear 10 and the first bevel gear 9 are always kept in meshing state, while improving the smoothness of rotation.

[0047] Working principle: by moving the temporary support device to the bottom of the temporary concrete to be supported, and then starting the motor 6, the motor 6 drives the first screw rod 7 to rotate around the first bearing seat 18, and the first screw rod 7 rotates while driving the connecting block 8 and the support rod 4 to move upward under the restriction of the sleeve 3, and the support rod 4 drives the support plate 2 to move upward until the support plate 2 contacts the temporary concrete to be supported, and the support is completed;

[0048] When the motor 6 rotates, the first bevel gear 9 is driven to rotate. The first bevel gear 9 is meshed with the second bevel gear 10, so the second bevel gear 10 and the second screw rod 11 are driven to rotate around the second bearing seat 20. When the second screw rod 11 rotates, the push block 12 and the push rod 13 are driven to move. Figure 2 As shown, the counterweight block 14 is opened to both sides, thereby increasing the contact area with the ground and improving the stability of the temporary support device.

[0049] It should be noted that the motor 6 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 6 are clear to those skilled in the art, so they are not described in detail.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
