[0017] 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.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Traditional formwork equipment for road and bridge construction is relatively troublesome to use and install, relying too much on welding or bolt fixing for installation, which leads to high labor intensity and relatively low work efficiency for workers, thus causing inconvenience to workers.

[0020] In view of this, the present invention provides a fixed formwork device for road and bridge construction. Through the cooperation of a first base plate, a second base plate, a clamping device and a splicing device, rapid assembly can be carried out without relying on too many bolts and welding structures, thus improving the convenience of installation. At the same time, disassembly after use is also relatively simple, thereby effectively improving the overall work efficiency. In addition, the whole equipment can be transported in a decentralized manner, which can reduce the transportation volume and improve the convenience of transportation.

[0021] Example 1: By Figure 1 , 2 As shown in sections 3 and 4, a formwork device for road and bridge construction includes a first base plate 1, a second base plate 4 attached to one side of the first base plate 1, and a clamping device 2 above the first base plate 1 and the second base plate 4. The clamping device 2 includes: two clamping plates 21, respectively located above the first base plate 1 and the second base plate 4; two first connecting blocks 22, respectively fixedly connected to the outer walls of the two clamping plates 21; two first threaded rods 23, respectively rotatably connected to the inner walls of the two first connecting blocks 22 via bearings; two vertical plates 25, respectively fixedly connected to the tops of the first base plate 1 and the second base plate 4, and respectively threadedly connected to the outer walls of the two first threaded rods 23; and multiple limiting rods 24, respectively fixedly connected to the outer walls of the two clamping plates 21, and respectively inserted into the inner walls of the two vertical plates 25. The position of the clamping plate 21 is changed by twisting the first threaded rods 23, and the limiting rods 24 and the vertical plates 25 limit the clamping plate 21.

[0022] In the specific implementation process, it is worth noting that twisting the first threaded rod 23 can change the position of the clamping plate 21 so that the inner template of the road and bridge can be fixed by the two clamping plates 21, so as to avoid leakage caused by excessive internal pressure of the inner template. It should be noted that when using it, the clamping plate 21 of appropriate size and specifications should be selected, so that the inner template can be fixed and limited by the clamping plate 21. The limiting rod 24 can limit the clamping plate 21.

[0023] Furthermore, a curved plate 211 is inserted into one side of the two clamping plates 21 that are close to each other, and a support plate 212 is fixedly connected to one side of the two clamping plates 21 that are close to each other. A second threaded rod 213 is threadedly connected to the inner wall of the support plate 212.

[0024] In the specific implementation process, it is worth noting that the curved plate 211 can improve the stability when the two clamping plates 21 are connected, and the cooperation between the second threaded rod 213 and the support plate 212 also plays the role of improving the connection strength of the two clamping plates 21.

[0025] Specifically, when using the fixed formwork equipment for road and bridge construction, the workers place two clamping plates 21 on the outside of the inner formwork, then twist the first threaded rod 23. The first threaded rod 23 changes the position of the clamping plates 21 through the first connecting block 22. At the same time, the limiting rod 24 moves along the inner wall of the vertical plate 25. When the two clamping plates 21 move to the appropriate position, the curved plate 211 is then inserted into the groove of the two clamping plates 21. Then, the two support plates 212 are connected by the second threaded rod 213, and then it can be put into use.

[0026] Example 2: From Figure 1 , 2 As can be seen from points 3 and 4, a splicing device 3 is provided on the side of the first base plate 1 and the second base plate 4 that are close to each other. The splicing device 3 includes: two first insert plates 31, which are fixedly connected to the outer walls of the first base plate 1 and the second base plate 4 respectively, and are inserted into the corresponding grooves of the second base plate 4 and the first base plate 1 respectively; two second insert plates 32, which are inserted into the inner walls of the two first insert plates 31 respectively, and are respectively in contact with the grooves of the first base plate 1 and the second base plate 4; and two fixing screws 33, which are threadedly connected to the inner walls of the two second insert plates 32 respectively, and are respectively threadedly connected to the inner walls of the first base plate 1 and the second base plate 4. The fixing screws 33 limit the first insert plates 31 and the second insert plates 32, thereby limiting the first base plate 1 and the second base plate 4.

[0027] In the specific implementation process, it is worth noting that the fixing screw 33 can be threaded to fix the second insert plate 32 and the first base plate 1 and the second base plate 4. The cooperation of the first insert plate 31 and the second insert plate 32 can limit and fix the first base plate 1 and the second base plate 4.

[0028] Specifically, based on the above embodiment one, when assembling the fixed mold equipment used for road and bridge construction, the workers align the first base plate 1 and the second base plate 4, that is, the two first insert plates 31 are respectively inserted into the grooves of the first base plate 1 and the second base plate 4. Then, the second insert plate 32 is inserted into the inner wall of the two first insert plates 31. Then, the second insert plate 32 and the first base plate 1 and the second base plate 4 are threaded together using the fixing screws 33. At this time, the splicing work can be completed.

[0029] Example 3: From Figure 3 It is known that the bottom of the first base plate 1 and the second base plate 4 are provided with an installation device 5. The installation device 5 includes: two double-ended studs 51, which are rotatably connected to the bottom of the first base plate 1 and the second base plate 4 respectively through bearings; multiple second connecting blocks 52, which are threaded to both sides of the two double-ended studs 51 respectively, and are slidably engaged with the bottom limiting grooves 54 of the first base plate 1 and the second base plate 4 respectively; and multiple mounting plates 53, which are fixedly connected to the ends of the multiple second connecting blocks 52 respectively. The position of the mounting plate 53 is changed by twisting the double-ended studs 51, and the limiting grooves 54 and the second connecting blocks 52 limit the mounting plate 53.

[0030] In the specific implementation process, it is worth noting that twisting the double-headed stud 51 can change the position of the mounting plate 53. When the mounting plate 53 reaches the appropriate position, the fixed formwork equipment used for road and bridge construction can be installed on the external building. The cooperation of the limiting groove 54 and the second connecting block 52 can limit the mounting plate 53, so that it can only achieve simple reciprocating motion.

[0031] Furthermore, rubber pads 531 are fixedly connected to the outer walls of multiple mounting plates 53;

[0032] In the specific implementation process, it is worth noting that the staff should replace the rubber pad 531 regularly. There is no limit to the specific replacement cycle, which can be determined by the staff according to the actual operation situation, so as to ensure the quality of the rubber pad 531.

[0033] Specifically, based on the above embodiment 1, when the first base plate 1 and the second base plate 4 are fitted onto the external building, the worker twists the double-headed stud 51, which drives the second connecting block 52 to move along the inner wall of the limiting groove 54, thereby changing the position of the mounting plate 53. As multiple mounting plates 53 move closer to each other, the fixed formwork equipment used for road and bridge construction can be installed on the external building.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
