Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a building construction support device. Background Art

[0002] Among building auxiliary construction equipment, the support device is essential. Especially when pouring concrete for a roof or a wall, etc., it is necessary to support and fix the building formwork through the support device so that the concrete can be poured stably. The patent document with the application number 201821275211.6 discloses a building construction wall support device, which supports the wall surface through a fixed column and a lifting column. By adjusting the elongation amount of the lifting column inside the sliding groove and fixing it with a positioning pin, it can meet the support of walls with different heights. Although this device can play a supporting role, its connection method using fixed holes and positioning pins is such that the spacing of the fixed holes affects the adjustment range of the support device each time. There are problems of being too high or too low in the two adjustments during actual use, with poor applicability, and it is inconvenient to adjust as it requires two adjustments of the rotating disk and the positioning pin.

[0025] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed implementation mode of the present utility model will now be described in detail with reference to the accompanying drawings.

[0026] As Figure 1-7 shown, the building construction support device includes a base 1, a telescopic rod mechanism 2 hinged to one end of the base 1, and a telescopic frame mechanism 3 provided at the other end of the base 1.

[0027] The telescopic rod mechanism 2 includes a connecting sleeve 21, a connecting rod 22 slidably disposed within the connecting sleeve 21, a notch 23 opened at the lower part of the connecting sleeve 21, and a driving mechanism 4 provided at the position of the notch 23 of the sleeve for driving the telescopic movement of the connecting rod 22.

[0028] The telescopic frame mechanism 3 includes a bracket 31, a support rod 32 slidably disposed on the bracket 31, and a limiting mechanism provided on the bracket 31 for limiting the support rod 32. The limiting mechanism includes a ratchet tooth 33 provided on the support rod 32 and a lock tongue 34 provided on the frame for cooperating with the ratchet tooth 33. The end of the connecting rod is hinged to the end of the support rod 32.

[0029] The building construction support device includes a telescopic rod mechanism 2 and a telescopic frame mechanism 3 hinged to the base 1. Among them, the connecting rod 22 in the telescopic rod mechanism 2 can extend relative to the sleeve. During the telescopic process, the support rod 32 is driven to extend along the bracket 31, and the position of the support rod 32 is fixed through the limiting mechanism. The present utility model realizes the height adjustment through the driving mechanism 4 and the limiting mechanism, so as to adapt to the support of walls with different heights and thicknesses, and has stronger applicability. At the same time, during the adjustment, the height adjustment can be realized only by using the driving mechanism 4, and the adjustment is convenient and fast.

[0030] The driving mechanism 4 includes connecting plates 41 provided on both sides of the notch 23, a rotating shaft 42 provided on the connecting plates 41, a gear 43 provided on the rotating shaft 42, and a handle 44 connected to the rotating shaft 42. A rack 24 meshing with the gear 43 is provided on the connecting rod 22. When the handle 44 is shaken, the gear 43 rotates to realize the extension and retraction of the connecting rod 22. The connecting rod 22 is cylindrical, and a fixing piece is provided at the end of the support rod 32. The fixing piece can be used for fixing with the wall or with the formwork to achieve stable support.

[0031] The limiting mechanism further includes a sliding rod 35. The locking tongue 34 is connected to the front end of the sliding rod 35. A spring 36 is sleeved on the sliding rod 35, so that the locking tongue 34 is inserted into the ratchet teeth 33. There are two sets of limiting mechanisms, and there are two ratchet teeth 33 opened on the support rod 32. A slideway for the up-and-down sliding of the support rod 32 is arranged inside the bracket 31. The ratchet teeth 33 include a flat bottom surface and an inclined top surface. The locking tongue 34 includes a flat top surface and an inclined bottom surface. The slope of the bottom surface is the same as that of the top surface, and the locking tongue 34 is supported on the bottom surface. By adopting a flat bottom surface and an inclined top surface for the ratchet teeth 33, when raising, mainly by shaking the handle 44, the relative sliding of the support rod 32 with respect to the bracket 31 can be realized. When it is necessary to lower the height, the sliding rod 35 is pulled to disengage the locking tongue 34 from the ratchet teeth 33, and then the handle 44 is shaken to slowly lower the support rod 32 to the preset height.
