Description

Technical Field

[0001] This utility model relates to the field of bridge support structure technology, specifically a bridge construction support base device. Background Technology

[0002] In the construction of cast-in-place bridge beam supports, the foundation must first be hardened. Supports and longitudinal and transverse connecting rods are then erected on the hardened ground, and longitudinal and transverse beams are installed on the top surface of the supports. Next, formwork is erected, pre-stressing is performed, reinforcement is tied, and concrete is poured. During operation, various uncertainties can lead to support instability and engineering safety accidents due to excessive stress, large eccentric moments, insecure support connections, and the inability to monitor internal forces in a timely manner. Therefore, the support structure design, including the support base, working method, and stress monitoring, is crucial during the erection and operation of the supports. Researching a new type of bridge construction support base device can not only ensure stable operation of the supports but also provide flexibility and convenience in erection and dismantling. The components used in the construction supports can be reused multiple times, reducing construction costs, which is of great significance to construction units. Summary of the Invention

A third screw hole is vertically positioned, and the third screw hole is movably connected to the second screw hole via a through pin. A support groove is set at the center of the top surface of the support plate, and the top surface of the support groove is a hemispherical end rod. The top of the hemispherical end rod is fixedly connected to the bottom of the bracket. Reinforcing steel guard plates are set around the bottom of the bracket.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model provides one embodiment.

[0020] A bridge construction support base device includes a foundation 1, a support plate 2, a bracket 3, a connecting rod 4, hooks 5, bolts 6, a support groove 7, a hemispherical end rod 8, a stress monitoring plate 9, a reinforcing steel guard plate 10, a fixing plate 11, a nut 12, a first screw hole 13, a second screw hole 14, a third screw hole 15, a groove 16, a through nail 17, a computer monitoring system 18, and a level bubble 19. Support plates 2 are evenly distributed on the foundation 1. Hooks 5 are arranged around the perimeter of the support plates 2. A second screw hole 14 is vertically positioned at the center of each hook 5. The support plates 2 are connected to adjacent support plates 2 via connecting rods 4. A groove 16 is provided at the end of the connecting rod 4. The depth of the groove 16 is the same as the length of the hook 5, and the length of the groove 16 is the same as the thickness of the hook 5. A third screw hole 15 is vertically positioned at the center of the upper and lower edges of the groove 16. 5. The third screw hole 15 and the second screw hole 14 are movably connected by a through pin 17. A support groove 7 is set at the center of the top surface of the support plate 2. The top surface of the support groove 7 is a hemispherical end rod 8. The top of the hemispherical end rod 8 is fixedly connected to the bottom of the bracket 3. A reinforcing steel guard plate 10 is set around the bottom of the bracket 3. The bracket 3 passes through the fixing plate 11 and is welded perpendicularly to the fixing plate 11. Four first screw holes 13 are set vertically on the fixing plate 11. Bolt rods 6 are set vertically around the outside of the support groove 7. One end of the bolt rod 6 is embedded in the support plate 2, and the other end passes through the first screw hole 13 in the fixing plate 11 and is fixed to the fixing plate 11 by a nut 12. A stress monitoring plate 9 is installed between the nut 12 and the fixing plate 11. The stress monitoring plate 9 is connected to the computer monitoring system 18. Two spirit levels 19 are set at opposite corners of the fixing plate 11.

[0021] Furthermore, the support plate 2 is provided with ear hooks 5 around its perimeter, with two ear hooks 5 on each of the adjacent sides and one ear hook 5 on the other adjacent sides.

[0022] Furthermore, the radius of the ball head of the hemispherical end rod 8 matches the radius of the support groove 7.

[0023] Furthermore, the reinforced steel guard plate 10 has a thickness of 3mm and a length of 200mm.

[0024] Furthermore, the diameters of the second screw hole 14, the third screw hole 15, and the through pin 17 are the same.

[0025] Furthermore, the support groove 7 is made of concrete, and the support groove 7 and the support plate 2 are integrally cast.

[0026] First, after leveling the site and treating the foundation 1, several support plates 2 are installed longitudinally and laterally according to the length and width of the foundation 1. The distance between the support plates 2 is determined by the length of the connecting rod 4. Each support plate 2 is equipped with two sets of two ear hooks 5 and two sets of one ear hook 5 around its perimeter. The ear hooks 5 are inserted into the grooves 16 at the ends of the connecting rod 4. Then, the through nails 17 are passed into the second screw hole 14 and the third screw hole 15 respectively for assembly and connection.

[0027] The bracket 3 is vertically hoisted into the support groove 7 using a crane. At the same time, four bolt rods 6 are inserted into the first screw hole 13 on the fixing plate 11. Then, nuts 12 are screwed into the bolt rods 6 for initial fixation. The verticality of the bracket 3 is adjusted by the crane. When the level bubble 19 is in the center position, it indicates that the bracket 3 is in a vertical state. Then, the nuts 12 are tightened and the bracket 3 is initially fixed by the fixing plate 11.

[0028] After all the supports 3 are installed, the upper longitudinal and transverse connections of the supports 3 are made to ensure the stability of the supports 3. After the bridge formwork is installed, pre-stressing is performed, and the steel guard plate 10 is reinforced to ensure that the bottom of the supports 3 provides greater vertical bearing capacity. Then, the nuts 12 are finely adjusted and the supports 3 are finally fixed through the fixing plate 11.

[0029] When pouring concrete, the stress of the concrete's own weight is transferred to the foundation 1 through the support 3. When a certain support 3 experiences eccentric stress, the hemispherical end rod 8 will move slightly within the support groove 7 and automatically adjust the position of the hemispherical end rod 8, ultimately making the hemispherical end rod 8 work in coordination with the support groove 7. When a large eccentric stress occurs, the stress monitoring plate 9 will provide a prompt through the computer monitoring system 18. At this time, it is necessary to adjust the tightness of the nut 12 to ensure uniform stress and avoid stress concentration that could lead to engineering accidents.

[0030] After the concrete is poured and the concrete strength reaches the required level, the bridge formwork is unloaded, the support 3 is fixed with a crane, the nut 12 is loosened and the support 3 is hoisted, the connecting rod 4 is disassembled, and the support plate 2 is hoisted to complete the work of the bridge construction support base.

[0031] A bridge construction support base device includes a support plate 2, a bracket 3, a connecting rod 4, a lug 5, a bolt rod 6, a support groove 7, a hemispherical end rod 8, a stress monitoring plate 9, a reinforcing steel guard plate 10, a fixing plate 11, a nut 12, a first screw hole 13, a second screw hole 14, a third screw hole 15, a groove 16, a through nail 17, a computer monitoring system 18, and a spirit level 19. It can be reused multiple times, which not only saves construction costs but also makes installation and disassembly convenient.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
