Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, specifically a height-adjustable slope formwork support. Background Technology
[0002] Currently, the application of full-span formwork support systems on slopes is becoming increasingly common, such as in multi-functional lecture halls in schools, cinemas, and car ramps in multi-story basements. Formwork supports on slopes must address the stability of the formwork uprights on the inclined foundation. This includes handling the displacement of the upright base along the slope direction caused by loads parallel to the slope, as well as the rotational effect of the downward force of the top slab load on the upright base. Traditional construction techniques typically combine pre-embedded reinforcing bars with long wedge-shaped wooden blocks. This technique suffers from the problems of a large workload for pre-embedded reinforcing bars, a long construction period, and the tendency for pre-embedded reinforcing bars to shift during concrete pouring, requiring subsequent cutting and non-reusability, leading to resource waste and environmental pollution.
[0003] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content
[0004] To address the aforementioned shortcomings, the present invention aims to provide a height-adjustable slope formwork support frame. This frame utilizes a multi-level adjustable height base. After leveling the base, the formwork support frame uprights are erected on it. This ensures the flatness of the uprights' base and effectively limits the sliding displacement of the uprights' roots on the slope, thereby ensuring the stability and safety of the entire construction process.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A height-adjustable slope formwork support includes a base steel plate, an adjustable multi-level height steel plate, a bottom steel plate for uprights, rebar ends, and uprights. One end of the base steel plate is fixedly connected to the bottom end of the adjustable multi-level height steel plate, forming an angle of less than 90 degrees between the base steel plate and the adjustable multi-level height steel plate. Two or more slots are horizontally arranged at different heights from the bottom to the top of the adjustable multi-level height steel plate, penetrating through the plate. One end of the bottom steel plate of the upright abuts against the other end of the base steel plate, and the other end of the bottom steel plate extends into one of the slots on the adjustable multi-level height steel plate. A rebar end is provided in the middle of the upper surface of the bottom steel plate of the upright, and the upright is mounted on the rebar end.
[0007] Furthermore, there are three slots, which are respectively arranged at the bottom, middle and top of the adjustable multi-level height steel plate.
[0008] Furthermore, the base steel plate is also provided with screw holes and expansion bolts, which pass through the screw holes to fix the base steel plate to the installation slope.
[0009] Furthermore, a limit pin is also provided on the overlapping end of the bottom steel plate of the upright and the slot.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This invention uses expansion bolts to fix the base steel plate to the slope surface. The adjustable base is then fixed to the base plate with expansion bolts. For slopes of varying gradients, the bottom steel plate of the upright is leveled by inserting it into slots at different heights. The formwork support upright is then erected on top of the bottom steel plate. This ensures the flatness of the upright base and effectively limits the sliding displacement of the upright base on the slope, thus ensuring the stability and safety of the entire construction process.

[0015] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. In the description of these embodiments, it should be understood that terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing these embodiments and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0016] like Figure 1As shown, a height-adjustable slope formwork support includes a base steel plate 1, an adjustable multi-level height steel plate 2, a bottom steel plate 3 for uprights, a rebar head 4, and an upright 5. One end of the base steel plate 1 is fixedly connected to the bottom end of the adjustable multi-level height steel plate 2, and the base steel plate 1 and the adjustable multi-level height steel plate 2 form an angle of less than 90 degrees. The adjustable multi-level height steel plate 2 has two or more slots 6 arranged laterally at different heights from the bottom to the top. One end of the bottom steel plate 3 abuts against the other end of the base steel plate 1, and the other end of the bottom steel plate 3 extends into one of the slots 6 on the adjustable multi-level height steel plate 2. A rebar head 4 is provided in the middle of the upper surface of the bottom steel plate 3, and the upright 5 is installed on the rebar head 4.
[0017] In this embodiment, there are three slots 6, which are respectively arranged at the bottom, middle and top of the adjustable multi-level height steel plate 2.
[0018] In application, for existing multi-functional lecture halls, cinemas, and car ramps in multi-level basements of schools, the slope of the above-mentioned slope formwork is generally between 20 and 60 degrees. To accommodate slopes of 20 to 30 degrees, when installing the above-mentioned slope formwork, simply insert one end of the bottom steel plate of the upright into the slot located at the bottom of the adjustable multi-level height steel plate to level the bottom steel plate, and then erect the formwork upright on top of the bottom steel plate. To accommodate slopes of 30 to 40 degrees, when installing the above-mentioned slope formwork, simply insert one end of the bottom steel plate of the upright into the slot located in the middle of the adjustable multi-level height steel plate to level the bottom steel plate, and then erect the formwork upright on top of the bottom steel plate. To accommodate the installation of the above-mentioned slope formwork on steep slopes of 50 to 60 degrees, simply insert one end of the bottom steel plate of the upright into the slot at the top of the adjustable multi-level height steel plate to level the bottom steel plate. Then, the formwork uprights are erected on top of the bottom steel plate. The triangular support structure formed by the base steel plate, the adjustable multi-level height steel plate, and the bottom steel plate of the upright ensures the flatness of the base for erecting the uprights.
[0019] As a preferred embodiment of the above implementation, such as Figure 1 As shown, the base steel plate 1 is also provided with screw holes and expansion bolts 7. The expansion bolts 7 pass through the screw holes to fix the base steel plate 1 to the installation slope surface 8. This effectively limits the sliding displacement of the root of the formwork support pole on the slope surface, thereby ensuring the stability and safety of the entire construction process.
[0020] As a preferred embodiment of the above implementation, such as Figure 1As shown, a limit pin 9 is also provided on the overlapping end of the bottom steel plate 3 of the upright and the slot 6. This restricts the movement of the bottom steel plate 3 of the upright, further improving the stability and safety of the construction process.
[0021] This invention uses expansion bolts to fix the base steel plate to the slope surface. The adjustable base is then fixed to the base plate with expansion bolts. For slopes of varying gradients, the bottom steel plate of the upright is leveled by inserting it into slots at different heights. The formwork support upright is then erected on top of the bottom steel plate. This ensures the flatness of the upright base and effectively limits the sliding displacement of the upright base on the slope, thus ensuring the stability and safety of the entire construction process.
[0022] Although the present invention has been described in detail above with specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
