Then, according to the panel specifications of the roof, select the support frame of the appropriate length and quickly connect it to each support adjustment seat. At this time, each support frame is tilted downward, and then rotated and adjusted by the adjustment mechanism. The support frame is swung upward through the support adjustment seat, so that the top surface of each support frame is horizontally aligned with the top surface of the support column, so that the angle between each support frame and the support column is within 25 degrees. -45°, then the hydraulic jack rises, so that each support frame and support column rises to support the four sides and the middle of the bottom surface of the top plate, and then observe the pointing degree of the first pointer on the first angle disk, and then select a stabilizing rod of suitable length to be mounted on the stabilizing adjustment seat, and then adjust the telescopic adjustment piece so that the semicircular pressure plate is retracted into the arc-shaped pressure groove, and the first biting teeth and the second biting teeth bite into the angle between the stabilizing rod and the hydraulic jack, and then reversely twist the stabilizing rod to extend the stabilizing rod to press the ground and fix it;

[0023] When supporting the four side panels of a building, first move the hydraulic jack to the middle area of ​​the building, then quickly connect the support frame to each support adjustment seat, and then use the direction adjustment mechanism to rotate and adjust each support frame so that it swings upward to form a 90° angle between the horizontal and the hydraulic jack. Then raise the hydraulic jack and reversely twist the support frame so that the support frame extends to press against the middle area of ​​each side panel.

[0024] When only one side panel of the building is to be supported, first move the hydraulic jack to the side of the outer side of the side panel, then quickly connect a support frame to the corresponding support adjustment seat, and then quickly connect the stabilizing rod to the two stabilizing adjustment seats in the opposite direction, and then rotate and adjust the direction adjustment mechanism to make the support frame swing upward to form a 90° angle between the horizontal and the hydraulic jack, then raise the hydraulic jack, and then reversely twist the support frame so that the support frame extends to press the middle area of ​​the side panel, and then adjust the telescopic adjustment piece so that the semicircular pressure plate is retracted into the arc-shaped pressure groove, and the first biting tooth and the second biting tooth engage to fix the angle between the stabilizing rod and the hydraulic jack, and then reversely twist the stabilizing rod so that the stabilizing rod extends to press the ground and fix it.

[0025] The beneficial effects of the present invention are:

[0026] The present invention provides a construction support for civil engineering building construction and a construction method thereof. A construction support for civil engineering building construction is formed by a structural combination design of a support adjustment device consisting of a vertical seat group, a direction adjustment mechanism, a support adjustment seat, a stabilization adjustment seat, a support frame, and a stabilization push rod, and a hydraulic jack and a support column.

Only two or three sets of construction brackets of this product are needed to be staggered and installed to achieve multi-point stable pressure support for the four side formworks.

[0028] For the pressure support of a single side formwork, a support frame and two stabilizing rods in the same direction can be adjusted to be horizontally aligned to support the front, middle and rear points of the side formwork, while the two stabilizing rods in the opposite direction are adjusted to press against the ground and fix it. Only two sets of upper and lower height offsets are needed to achieve multi-point stable support for the side formwork.

[0049] The swing angle of each supporting adjustment seat 23 is 25-125°, and the swing angle of each stabilizing adjustment seat 24 is 25-155°.

[0050] Working principle:

[0051] When supporting the building roof, first move the hydraulic jack 1 to the bottom of the middle of the roof, and the initial swing angle of each support adjustment seat 23 is 125 degrees, and then select the support frame 25 of the appropriate length according to the panel specifications of the roof and quickly connect it to each support adjustment seat 23. At this time, each support frame 25 is tilted downward, and then rotated and adjusted by the adjustment mechanism 22, and the support frame 25 is swung upward through the support adjustment seat 23, so that the top surface of each support frame 25 is horizontally aligned with the top surface of the support column 3, so that the angle between each support frame 25 and the support column 3 is within the range of 25-45 degrees, and then the hydraulic The jack 1 rises, causing each support frame 25 and the support column 3 to rise and support the four sides and the middle of the bottom surface of the top plate. Then, observe the pointing degree of the first pointer 2314 on the first angle disk 233, and then select a stabilizing rod 26 of suitable length to be mounted on the stabilizing adjustment seat 24. Then, adjust the telescopic adjustment piece 245 so that the semicircular pressure plate 2432 is retracted into the arc-shaped pressure groove 2213, and the first biting tooth 2214 and the second biting tooth 2434 are engaged to fix the angle between the stabilizing rod 26 and the hydraulic jack 1. Then, twist the stabilizing rod 26 in the opposite direction so that the stabilizing rod 26 is extended to press against the ground and fixed.

[0052] It should be noted that when the direction adjustment mechanism 22 needs to be rotated and adjusted, the engagement between the first tooth 2214 and the second tooth 2434 on each stable adjustment seat 24 must first be canceled by twisting the telescopic adjustment member 245, so that the vertical lifting and lowering of the adjustment core 221 will not get stuck. The adjustment of the direction adjustment mechanism 22 is achieved by manually turning the handle 2245 in the forward and reverse directions to rotate the turbine 2244, driving the adjusting gear 2243 and the adjusting stud 2242 to rotate vertically on the rotating seat 2241. The adjusting stud 2242 is threadedly connected to the lifting threaded hole 2212 to make the adjusting core 221 rise and fall vertically. The swing angle adjustment of the first swing arm 231 on each support adjustment seat 23 is achieved through the engagement and positioning of the rack 2211 and the semicircular gear disk 2312.

[0053] In addition, the angle between each support frame 25 and the support column 3 is designed to be in the range of 25-45° so that the pressure force of the support frame 25 can be better transmitted to the two load-bearing seats 232, so that the engagement between the rack 2211 and the semicircular gear plate 2312 is not easily subjected to large oblique stress.

[0054] In addition, the degree of the first pointer 2314 pointing to the first angle plate 233 is observed in order to enable the adjustment of the stabilizing adjustment seat 24 to be accurately adjusted to an angle close to the supporting adjustment seat 23, so that the deployment angles of the supporting frame 25 and the stabilizing support rod 26 are close, thereby enhancing the stability of the hydraulic jack 1.

[0055] In addition, when the stable adjustment seat 24 is adjusted to abut against the adjustment core 221, the adjusting screw 2452 on the telescopic adjustment member 245 is rotated to make the threaded connection between the adjusting screw 2452 and the screw telescopic seat 2453 telescope, pulling the second swing arm body 2431 to slide left and right in the swing slide 241, thereby realizing the pressing and disengagement of the semicircular pressure plate 2432 in the arc-shaped pressure groove 2213.

[0056] When supporting the four side panels of a building, the hydraulic jack 1 is first moved to the middle area of ​​the building. Then, the support frame 25 is quickly connected to each support adjustment seat 23. Then, the direction adjustment mechanism 22 is rotated and adjusted so that each support frame 25 swings upward to form a 90° angle with the hydraulic jack 1. Then, the hydraulic jack 1 is raised and the support frame 25 is reversed to extend and press against the middle area of ​​each side panel. The support column 3 and the stabilizing rod 26 do not need to be installed.

[0057] When only one side panel of the building is to be supported, the hydraulic jack 1 is first moved to the side of the outer side of the side panel, and then a support frame 25 is quickly connected to the corresponding support adjustment seat 23, and then the two stable adjustment seats 24 in the opposite direction are also quickly connected to the stable push rod 26, and then the direction adjustment mechanism 22 is rotated and adjusted to make the support frame 25 swing upward to form a 90° angle between the horizontal and the hydraulic jack 1, and then the hydraulic jack 1 is raised, and then the support frame 25 is reversed to make the support frame 25 extend to press the middle area of ​​the side panel, and then the telescopic adjustment piece 245 is adjusted to make the semicircular pressure plate 2432 retract into the arc-shaped pressure groove 2213, and the first biting tooth 2214 and the second biting tooth 2434 engage with each other to fix the angle between the stable push rod 26 and the hydraulic jack 1, and then the stable push rod 26 is reversed to make the stable push rod 26 extend to press the ground and fix it.

[0058] It should also be noted that the three support methods provided above are not all support methods of the product of the present invention. In specific places, each stabilizing adjustment seat 24 and each stabilizing support rod 26 can also be adjusted to provide auxiliary support for the paired templates.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

The support frame is swung upward through the support adjustment seat, so that the top surface of each support frame is horizontally aligned with the top surface of the support column, so that the angle between each support frame and the support column is within 25 degrees. -45°, then the hydraulic jack rises, so that each support frame and support column rises to support the four sides and the middle of the bottom surface of the top plate, and then observe the pointing degree of the first pointer on the first angle disk, and then select a stabilizing rod of suitable length to be mounted on the stabilizing adjustment seat, and then adjust the telescopic adjustment piece so that the semicircular pressure plate is retracted into the arc-shaped pressure groove, and the first biting teeth and the second biting teeth bite into the angle between the stabilizing rod and the hydraulic jack, and then reversely twist the stabilizing rod to extend the stabilizing rod to press the ground and fix it; When supporting the four side panels of a building, first move the hydraulic jack to the middle area of ​​the building, then quickly connect the support frame to each support adjustment seat, and then use the direction adjustment mechanism to rotate and adjust each support frame so that it swings upward to form a 90° angle between the horizontal and the hydraulic jack. Then raise the hydraulic jack and reversely twist the support frame so that the support frame extends to press against the middle area of ​​each side panel. The support column and stabilizing rod do not need to be installed. When only one side panel of the building is to be supported, first move the hydraulic jack to the side of the outer side of the side panel, then quickly connect a support frame to the corresponding support adjustment seat, and then quickly connect the stabilizing rod to the two stabilizing adjustment seats in the opposite direction, and then rotate and adjust the direction adjustment mechanism to make the support frame swing upward to form a 90° angle between the horizontal and the hydraulic jack, then raise the hydraulic jack, and then reversely twist the support frame so that the support frame extends to press the middle area of ​​the side panel, and then adjust the telescopic adjustment piece so that the semicircular pressure plate is retracted into the arc-shaped pressure groove, and the first biting tooth and the second biting tooth engage to fix the angle between the stabilizing rod and the hydraulic jack, and then reversely twist the stabilizing rod so that the stabilizing rod extends to press the ground and fix it.
