[0031] Reference Figure 1-4 The invention discloses an adjustable support device for concrete formwork, which is used for supporting building formwork in order to ensure the integrity and durability of the structure formed by concrete and to facilitate supporting concrete formworks of different sizes.

[0032] The concrete formwork adjustable support device comprises two vertical supports 1, a horizontal support 3, a threaded rod 2 and two support components;

[0033] The two vertical supports 1 are arranged vertically and in parallel, and the vertical supports 1 are made of rectangular steel with a size of 50 mm×25 mm and a wall thickness of 2 mm.

[0034] The cross brace 3 is arranged between the two vertical braces 1 and located at the upper part of the two vertical braces 1, so as to facilitate the pouring of concrete at the bottom of the two vertical braces 1. The cross brace 3 located at the upper part will not destroy the integrity and durability of the structure formed by the concrete. The two end portions of the cross brace 3 are bent upward into an L shape to form a connecting portion, and fit with the inner side of the vertical brace 1. Ribs 302 are welded to the connecting portions at both ends of the cross brace 3 to strengthen the structural strength of the L-shaped connecting portion. A plurality of reinforcing plates 301 are welded on the cross brace 3, and a first through hole is provided on each reinforcing plate 301 and the connecting portion, and the threaded rod 2 passes through each first through hole, so as to facilitate the assembly connection between the threaded rod 2 and the cross brace 3. A plurality of reinforcing plates 301 can strengthen the connection strength between the threaded rod 2 and the cross brace 3. The length of the cross brace 3 is less than 300 mm, and cross braces 3 of different lengths can be selected according to the concrete pouring size, so as to facilitate the adjustment of the support device according to the size.

[0035] A fixing groove 101 is provided on the top of the two vertical supports 1. The fixing groove 101 is vertical. The diameter of the threaded rod 2 is smaller than the width of the fixing groove 101, so that the threaded rod 2 can be easily placed into the fixing groove 101 from top to bottom, and the assembly between the threaded rod 2, the horizontal support 3 and the vertical support 1 is convenient. A fixing block 102 is fixedly connected to the inner side of the vertical support 1. The fixing block 102 is located above the horizontal support 3. The fixing block 102 can limit the horizontal support 3 downward, so that the threaded rod 2 is fixed inside the fixing groove 101. The setting of the fixing groove 101 makes it easy for the threaded rod 2 to be combined and connected with the vertical support 1, which is convenient for the assembly and use of the support device.

[0036] The two support assemblies are symmetrically arranged at the two ends of the threaded rod 2, and each support assembly includes a first nut 4, a first support member 5, a second nut 6 and a second support member 7. The first support member 5 and the second support member 7 are both made of channel steel. The upper ends of the first support member 5 and the second support member 7 are each provided with a second through hole. The diameter of the second through hole is larger than that of the threaded rod 2. The threaded rod 2 passes through the second through hole. The first nut 4 is threadedly connected to the outside of the threaded rod 2. Rotating the first nut 4 can move it toward the middle. Since the upper end of the first support member 5 is vertical and perpendicular to the axis of the threaded rod 2, it is convenient to make the upper end of the first support member 5 squeeze the vertical support 1 inward. Under the action of the two first nuts 4, the two vertical supports 1 are fixed at the two ends of the horizontal support 3.

[0037] The first support member 5 and the second support member 7 are arranged obliquely, and an opening is opened at the lower end of the first support member 5, and the opening is U-shaped, so that the second support member 7 can pass through the U-shaped opening, and a fixed shaft 8 is fixedly connected at the opening, and the middle part of the second support member 7 is rotatably connected to the lower end of the first support member 5 through the fixed shaft 8, so that the first support member 5 and the second support member 7 are combined into a "y" shape, and the second nut 6 is threadedly connected to the outside of the threaded rod 2. By rotating the second nut 6, the second nut 6 can be moved toward the end of the threaded rod 2, and since the upper end of the second support member 7 is vertical and perpendicular to the axis of the threaded rod 2, it is convenient to make the upper end of the second support member 7 on the threaded rod 2 to be forced to move outward, and since the middle part of the second support member 7 is restricted by the rotation of the lower end of the first support member 5, the lower end of the second support member 7 will be forced to move inward, thereby squeezing the vertical support 1 inward, and the two second support members 7 cooperate with each other so that the lower parts of the two vertical supports 1 are fixed to the middle by force, and cooperate with the cross support 3 to support the formwork, which is convenient for pouring concrete in the formwork.

[0038] A support plate 9 is welded to the lower end of the second support member 7 , and one side of the support plate 9 is attached to the outer side of the vertical support 1 , so that the lower end of the second support member 7 can stably support the vertical support 1 .

[0039] The concrete formwork adjustable support device can be provided in plurality, each of which can support a part of the concrete formwork.

[0040] The working principle of the adjustable support device of the concrete formwork is as follows: first, according to the width size of the concrete pouring, different lengths of the horizontal braces 3 are selected, and then the assembly is performed, and the threaded rod 2 is passed through the L-shaped connecting portion on the selected horizontal brace 3 and the first through hole on the reinforcing plate 301, so that the threaded rod 2 is fixed to the horizontal brace 3, and then the threaded rod 2 is placed downward into the fixing groove 101 of the vertical brace 1, and the vertical brace 1 is brought under the fixing block 102, and then the first support member 5, the first nut 4, the second nut 6 and the second support member 7 are passed through the second through hole on the end of the threaded rod 2, thereby completing the assembly of the support device;

[0041] When the supporting device is assembled and the formwork is fixed, first rotate the first nuts 4 at both ends of the threaded rod 2, and the two first nuts 4 move toward the middle of the threaded rod 2. While squeezing and fixing the first support member 5 toward the middle, squeeze the two vertical supports 1 toward the middle, so that the two vertical supports 1 are respectively fixed to the two ends of the cross support 3, so that the upper parts of the two vertical supports 1 are fixed. At this time, the first support member 5 is also fixed, and then the second nuts 6 at both ends of the threaded rod 2 are rotated, and the two second nuts 6 move toward the ends of the threaded rod 2, so that the upper ends of the two second supports 7 are forced to move outward. Since the middle part of the second support member 7 is restricted by the rotation of the lower end of the first support member 5, the lower end of the second support member 7 will be forced to move inward, so the lower end of the second support member 7 will squeeze the vertical support 1 inward, so that the lower parts of the two vertical supports 1 are forced to be fixed toward the middle, thereby completing the comprehensive fixation of the two vertical supports 1, which is convenient for supporting the formwork.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
