Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a steel formwork for the construction of a continuous concrete beam bridge. Background Technology

[0002] Steel formwork used in the construction of continuous concrete beam bridges is a temporary structure for pouring concrete. It has high strength, rigidity and durability. Steel formwork can withstand the weight of concrete and construction loads, ensuring structural stability. It can be reused multiple times and is suitable for large-scale construction.

[0003] The existing steel formwork used in the construction of continuous concrete beam bridges requires the use of fixing bolts to secure the connected steel formwork during assembly. This results in the need to tighten multiple fixing bolts during the connection process, making the installation inconvenient. Furthermore, the existing steel formwork used in the construction of continuous concrete beam bridges is quite heavy, requiring it to be moved to a designated location during assembly, which increases the labor intensity of the workers. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to again Figure 1-5This utility model provides a steel formwork for the construction of a continuous concrete beam bridge, including a base 100. Storage compartments 110 are fixedly connected to the front and rear sides of the bottom of the base 100, and a transmission compartment 120 is fixedly connected to the right side wall of the base 100. The base 100 is characterized by having a moving mechanism inside, including a first gear driven screw 130. The first gear driven screw 130 is rotatably connected to the left and right sides of the bottom of the inner cavity of the base 100. The bottom end of the first gear driven screw 130 penetrates the base 100 and extends into the inner cavity of the storage compartment 110. A first threaded sleeve 131 is screwed onto the outer side wall of the first gear driven screw 130. An mounting plate 140 is fixedly connected between the bottom ends of the first threaded sleeves 131 on the left and right sides. The bottom left and right sides of the base 100 are rotatably connected to movable wheels 141. The left side wall of the inner cavity of the transmission chamber 120 is rotatably connected to gear transmission rods 150. The left end of the gear transmission rod 150 passes through the transmission chamber 120 and extends into the inner cavity of the base 100. The left and right sides of the outer side wall of the gear transmission rod 150 are fixedly connected to the first drive gear 151. The first drive gear 151 is meshed with the first gear driven screw 130. The front side wall of the transmission chamber 120 is rotatably connected to a rotating rod 160. The rear end of the rotating rod 160 passes through the transmission chamber 120 and extends into the inner cavity of the transmission chamber 120. The front and rear sides of the outer side wall of the rotating rod 160 are fixedly connected to the second drive gear 161. The second drive gear 161 is meshed with the gear transmission rod 150.

[0023] Specifically, when the position of the steel template needs to be adjusted, rotating the rotating rod 160 causes the second drive gear 161 on the rotating rod 160 to drive the gear transmission rod 150 meshing with it to rotate, causing the first drive gear 151 on the gear transmission rod 150 to drive the first gear driven screw 130 meshing with it to rotate, causing the first threaded sleeve 131 installed at the bottom of the gear driven screw to descend, causing the mounting plate 140 installed at the bottom of the first threaded sleeve 131 to descend, causing the moving wheel 141 at the bottom of the mounting plate 140 to descend and contact the ground, allowing the steel template to be moved to the designated location. After the movement is completed, reversing the rotating rod 160 will cause the mounting plate 140 to rise, causing the moving wheel 141 to move into the storage compartment 110.

[0024] Example 2: Please refer to again Figure 1-5The template body 200 is fixedly connected to the top of the base 100. The upper and lower sides of the rear side wall of the template body 200 are fixedly connected to the inserts 210. The template body 200 is provided with a connecting mechanism, which includes a second gear driven screw 220. The second gear driven screw 220 is rotatably connected to the top and bottom of the inner cavity of the template body 200. The ends of the upper and lower sides of the second gear driven screw 220 extend into the interior of the template body 200. The outer side walls of the upper and lower sides of the second gear driven screw 220 are screwed with second threaded sleeves 221. The ends of the upper and lower sides of the second threaded sleeves 221 are fixedly connected with latches 222. The rear side wall of the template body 200 is rotatably connected to a gear drive rod 230. The left end of the gear drive rod 230 passes through the template body 200 and extends into the inner cavity of the template body 200. The left end of the gear drive rod 230 is engaged with the upper and lower sides of the second gear driven screw 220.

[0025] Specifically, when connecting and assembling adjacent steel formwork, the insert 210 on one side of the formwork body 200 is inserted into the other side of the formwork body 200. Then, the gear drive rod 230 is rotated to drive the two second gear driven screws 220 meshing with it, causing the second threaded sleeve 221 installed on the second gear driven screw 220 to move. The latch 222 installed on the second threaded sleeve 221 moves synchronously and is inserted into the insert 210 to fix the formwork body 200, thus completing the connection and assembly of the two side formwork bodies 200. When separating the two side formwork bodies 200, the gear drive rod 230 is reversed.

[0026] Working principle: When the position of the steel formwork needs to be adjusted, rotating the rotating rod 160 causes the second drive gear 161 on the rotating rod 160 to drive the gear transmission rod 150 meshing with it to rotate. This causes the first drive gear 151 on the gear transmission rod 150 to drive the first gear driven screw 130 meshing with it to rotate. This causes the first threaded sleeve 131 installed at the bottom of the gear driven screw to descend, which in turn causes the mounting plate 140 installed at the bottom of the first threaded sleeve 131 to descend. This causes the moving wheel 141 at the bottom of the mounting plate 140 to descend and contact the ground, allowing the steel formwork to be moved to the designated location. After the movement is completed, reversing the rotating rod 160 will allow the mounting plate 140 to... The mechanism rises, causing the moving wheel 141 to move into the storage compartment 110. When connecting and assembling adjacent steel templates, the insert 210 on one side of the template body 200 is inserted into the template body 200 on the other side. Then, the gear drive rod 230 is rotated to drive the two second gear driven screws 220 meshing with it, causing the second threaded sleeve 221 installed on the second gear driven screw 220 to move. The latch 222 installed on the second threaded sleeve 221 moves synchronously and is inserted into the insert 210 to fix the template body 200, thus completing the connection and assembly of the two template bodies 200. When separating the two template bodies 200, the gear drive rod 230 is reversed.
