Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a post-blocking support device for building construction openings. Background Technique

[0002] In building construction, setting openings is a common construction requirement, such as for installing pipelines, cables or as temporary passageways to facilitate material transportation and personnel access. After the main structure construction is completed, these openings must be effectively blocked to ensure the overall structural safety and waterproof performance of the building. After the openings are used, they need to be blocked. Currently, the formwork support device used for blocking openings includes a blocking plate sized to fit the opening and a support structure below the blocking plate. The blocking plate is used to close the material transfer opening below the material transfer opening, and a large number of wooden squares and steel pipes are used to support the blocking plate. The lengths of these materials are fixed, resulting in difficulty in precisely controlling the spacing between the blocking plate during the erection process. To fill the gaps between these fixed-length materials, construction workers often need to insert wooden chips. The above operation process has numerous procedures during demolition, erection, and transportation, consuming a large amount of time, manpower, and material resources, not only increasing the construction cost but also possibly delaying the construction progress. Content of the Utility Model

[0003] To make up for the above deficiencies, the utility model provides a post-blocking support device for building construction openings to solve the above problems.

Specific embodiments

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figure 1-2As shown in the figure, the utility model provides a post-sealing support device for building construction openings, which includes a support base 10. A telescopic support rod 20 is arranged on the top of the support base 10. The telescopic support rod 20 includes an inner square tube 21 and an outer square tube 23. The inner square tube 21 is arranged on the top of the support base 10. A rack 22 is arranged on one side of the inner square tube 21. The outer square tube 23 sleeves the inner square tube 21 from the top of the inner square tube 21, and an activity groove 2301 is opened at the intersection with the rack 22. A telescopic control device 30 is arranged on one side of the outer square tube 23 close to the activity groove 2301. The telescopic control device 30 meshes with the rack 22. When adjusting the telescopic control device 30, the outer square tube 23 moves in the length direction of the inner square tube 21. A support plate 40 is detachably arranged on the top of the outer square tube 23. During use, the support base 10 and the support plate 40 can be quickly assembled on the telescopic support rod 20, and then the support device supports the sealing plate by manually adjusting the telescopic control device 30. This support device can flexibly adjust the distance between the support plate 40 and the sealing plate, simplify the construction process and improve the construction efficiency, which is of great significance for improving the overall quality and efficiency of building construction.

[0024] In this embodiment, the support base 10 includes a bottom plate 11. A sleeve 12 is arranged at the center of the top of the bottom plate 11. A plurality of reinforcing plates 13 are arranged between the sleeve 12 and the bottom plate 11. The reinforcing plates 13 are used to increase the connection strength between the sleeve 12 and the bottom plate 11. The inner square tube 21 is arranged inside the sleeve 12. The inner square tube 21 can be directly inserted into the sleeve 12, providing basic stability for this support device and avoiding the telescopic support rod 20 from shifting during the support process. If it needs to be more stable, threaded holes can be opened on the sleeve 12 and the inner square tube 21, and they can be further fixed by threads.

[0025] Furthermore, a connection screw 2302 is arranged on the top of the outer square tube 23, and a threaded cylinder 41 is arranged on the bottom of the support plate 40. The threaded cylinder 41 is threadedly connected with the connection screw 2302. Thus, the support base 10, the telescopic support rod 20 and the support plate 40 form a complete support structure.

[0026] As Figure 3 shown in the figure, a first limit baffle 2101 is arranged on one side of the outer side of the inner square tube 21 above the rack 22. The width of the first limit baffle 2101 is less than the width of the activity groove 2301. A second limit baffle 2304 is arranged on one side of the outer side of the outer square tube 23 above the activity groove 2301. A flange 2303 is arranged at the bottom end of the outer side of the outer square tube 23. When the telescopic support rod 20 is fully retracted, the first limit baffle 2101 and the second limit baffle 2304 are in contact with each other, and the flange 2303 is in contact with the sleeve 12.

[0027] As Figure 4-5As shown, the telescopic control device 30 includes a box body 31 and a fixing member 35. One end of the fixing member 35 is an opening. The fixing member 35 is arranged on the outer side of the outer square tube 23 near the bottom side, and the opening and the movable groove 2301 are in the same direction. The opening is connected by bolts at one side edge of the box body 31.

[0028] In this embodiment, a side groove 3102 is formed on the side of the box body 31 close to the rack 22. A worm 33 is arranged on the inner side of the box body 31 near the bottom side. The worm 33 penetrates to the outside in the direction away from the side groove 3102. A gear 32 is arranged in the middle of the box body 31. The gear 32 extends to the outside of the side groove 3102 and meshes with the rack 22. The gear 32 meshes with the worm 33. A handle 34 is further included. The handle 34 is arranged at the end of the worm 33. When the handle 34 is rotated, the worm 33 drives the gear 32 to rotate, so that the box body 31 drives the outer square tube 23 to move in the length direction of the inner square tube 21. This telescopic adjustment method solves the problem in the prior art that it is difficult to accurately control the distance between the fixed-length material and the sealing plate, and has simple assembly, simplifies the construction process, and reduces the construction cost.

[0029] The above further describes the present invention with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art after reading the above embodiments belong to the scope protected by the present invention.
