DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Traditional toll islands are constructed with wooden formwork. Construction workers need to read the drawings carefully and support the formwork according to the drawings. After the support is completed, the lower layer of the island tail, island body and island head is poured. After the strength reaches the specification requirements, the upper layer of the island head is poured. Finally, after the solidification is completed, the formwork needs to be removed for secondary trimming and grinding. The whole construction process is relatively cumbersome, and the support of the island head is more difficult. Not only the strength of the formwork must be ensured, but also the appearance must meet the design requirements. The toll island of the smart toll station is overall horizontally compressed, which makes it more difficult to use wooden formwork for the island head and tail, thus reducing the construction efficiency to a certain extent and increasing the construction cost. Based on this, the following solution is provided.

[0025] Example 1

[0026] The existing toll island is constructed using wooden formwork. Workers will build wooden formwork according to the drawings and pour a certain amount of concrete after the formwork is completed. Since the island head 2 is divided into two layers, and the upper island head 2 can only be poured after the concrete strength of the lower island head 2 reaches the standard, the time cost of construction is increased. This embodiment provides an integrated forming device for the head and tail of a highway toll island, such as Figure 1-Figure 3As shown, it includes an island body 1, with an island head 2 and an island tail 3 at both ends of the island body 1, and two groups of connecting mechanisms 4 are symmetrically provided on the surface of the island body 1 to connect the island head 2 and the island tail 3 respectively. When workers need to build a charging island, they will use machinery to lift the island tail 3, the island body 1 and the island head 2 to the site, and install them at the corresponding positioned positions of the island tail 3, the island body 1 and the island head 2. The connecting mechanism 4 is used to quickly connect the island tail 3, the island body 1 and the island head 2, so that the island tail 3, the island body 1 and the island head 2 form a whole, and then bolts, etc. are used. The fixing components fix the island tail 3, the island body 1 and the island head 2 to the ground. After the fixing is completed, a complete island head 2 and island tail 3 inner cavity is formed inside, and the steel bars are tied into the inner cavity. Concrete is poured into the island head 2 and island tail 3 can be cast and formed in one time, which is beneficial to avoid the uncertain influence brought by the secondary casting. After the concrete solidifies, the workers can directly use the connecting mechanism 4 to remove the mold, and use the machinery to transport the island tail 3, the island body 1 and the island head 2 away, which is beneficial for the workers to use the integrated molding device again, thereby greatly reducing the construction cost.

[0027] The connecting mechanism 4 includes a plurality of L-shaped plates 41 arranged on both sides of the island head 2 and the island body 1. The surfaces of the island tail 3, the island body 1 and the island head 2 are all provided with L-shaped plates 41, and the L-shaped plates 41 on the surface of the island body 1 correspond to the L-shaped plates 41 on the surfaces of the island tail 3 and the island head 2 one by one and are placed opposite to each other. Nuts 42 are arranged inside the plurality of L-shaped plates 41, and the nuts 42 are fixed inside the L-shaped plates 41. When the screw 43 rotates, the nuts 42 drive the L-shaped plates 41 to move on the surface of the screw 43, so that the two The L-shaped plates 41 are close to each other, and a screw 43 threadedly connected to the nut 42 is provided between the two corresponding L-shaped plates 41 on the surface of the island head 2 and the island body 1. When the worker controls the screw 43 to rotate, the island tail 3, the island body 1 and the island head 2 are connected and fixed to each other. A positioning piece 44 is provided between the island head 2 and the island body 1 to position, connect and fix the island head 2 and the island body 1, so that the island tail 3, the island body 1 and the island head 2 are kept horizontal when connected, so that the formed charging island is neat and beautiful. The island tail 3 and the island head 2 are connected to the island body 1, and stress is generated inside one side of the island tail 3 and the island head 2, so that the positioning member 44 is squeezed against each other, which is conducive to the connection and fixation between the island tail 3, the island body 1 and the island head 2. When the worker operates the machine to lift the island tail 3, the island body 1 and the island head 2 to the marked position on the ground, the island head 2 is first fixed to the marked position on the ground with bolts and other fixing parts, and then the island body 1 is placed on one side of the island head 2, and the position of the island body 1 is confirmed by the positioning member 44. At this time, the screw 43 is rotated to make the two L-shaped plates 41 close to each other, so that the stress between the island head 2 and the island body 1 connects and fixes the two. Similarly, the island tail 3 is placed on one side of the island body 1, and after the positioning member 44 confirms the position, the screw 43 is rotated to fix the island tail 3 to one side of the island body 1, which is conducive to the workers to quickly build the templates of the island tail 3, the island body 1 and the island head 2, and it is convenient for the workers to remove the templates later.

[0028] When a worker turns the screw rod 43, he will use two nuts 42 to slide on the surface threads of the screw rod 43. When the thread groove 45 of the screw rod 43 is generally rotated in one direction, the two nuts 42 will slide in the same direction and will not move in the opposite direction. Moreover, the worker cannot directly apply a rotational force to the screw rod 43. Two end surfaces of the screw rod 43 are symmetrically provided with two sections of thread grooves 45 with opposite threads. A connecting portion 46 is provided in the middle of the screw rod 43. A through groove 47 is provided in the connecting portion 46. A long rod 48 sliding in the through groove 47 is provided in the connecting portion 46. Limiting balls 49 are provided at both ends of the long rod 48. When the worker is between the fixed island body 1 and the island head 2, he will hold one end of the long rod 48. Because limiting balls 49 are provided at both ends of the long rod 48 and the limiting balls 49 are all made of iron, and a magnet 410 that is magnetically attracted to the limit ball 49 is provided in the connecting part 46, so the long rod 48 can move linearly in the connecting part 46 under gravity or human control and be fixed at a certain position of the through groove 47, which is conducive to adjusting the position of the long rod 48 to prevent affecting the normal use of the workers. At the same time, when the workers drive the screw 43 to rotate by rotating the long rod 48, the sliding long rod 48 can increase the torque, so that the workers apply a smaller force to drive the screw 43 to rotate, and because the threads at both ends of the screw 43 are opposite, when the screw 43 rotates in one direction, the two nuts 42 slide in opposite directions at the same time, which is conducive to reducing the workers' fixation or removal of the island tail 3, the island body 1 and the island head 2 molds, and reducing the workers' workload.

[0029] Because it is necessary to ensure that the completed toll island is more neat and beautiful and to reduce the trimming and grinding of the toll island by subsequent workers, it is necessary to keep the position and shape of the toll island mold adjusted before pouring. The positioning member 44 includes a plurality of positioning holes 441 arranged on the inner side of the island head 2, and the inner side of the island body 1 is symmetrically provided with positioning rods 442 for engaging with the positioning blocks. Before the workers fix the molds of the island tail 3, the island body 1 and the island head 2, they first put the positioning holes 441 on the surfaces of the island tail 3 and the island head 2 on the surfaces of the positioning rods 442 corresponding to the surfaces of the island body 1. When the positioning rods 442 are engaged with the positioning holes 441 at the corresponding positions, it means that the island tail 3, the island body 1 and the island head 2 are in a horizontal position, and when the screw 43 rotates to make the L-shaped plates 41 approach each other and stop moving, the stress between the positioning holes 441 and the positioning rods 442 cooperates with the friction force of the screw 43 on the L-shaped plate 41 to fix the island tail 3 or the island head 2 on one side of the island body 1.

[0030] Example 2

[0031] Because the screw 43 is independent of the island tail 3, the island body 1 and the island head 2 before use, workers need to store the screw 43 independently, and it will be transported as an accessory, which may easily lead to the loss of the screw 43. In addition, if one screw 43 is missing, the island tail 3, the island body 1 and the island head 2 are easily loosened when they are fixed, which is not conducive to the stable connection between the island tail 3, the island body 1 and the island head 2. Based on Example 1, Figure 4 As shown, active areas 411 are provided at both ends of the screw 43, and a blocking block 412 is provided on one side of the screw 43 close to the island body 1, and a cross block 413 is provided on one side of the blocking block 412 for manually rotating the screw 43, and a fixing frame 414 is provided on the surface of the island body 1, and a circular groove 415 is provided in the fixing frame 414 for the blocking block 412 to rotate and slide, and a blocking plate 416 is provided on one side of the circular groove 415. Since a through hole 417 is provided in the fixing frame 414 for the screw 43 to pass through, the inner diameter of the through hole 417 is larger than the inner diameter of the screw 43, and the depth of the circular groove 415 is equal to the width of the blocking block 412, so that before the screw 43 is used, the active area 411 at one end of the screw 43 is 11 is in contact with the nut 42, and due to the existence of the blocking plate 416, the screw 43 will not be separated from the L-shaped plate 41 on the island body 1, and the worker will be guided by the rotating cross block 413 to control the blocking block 412 to rotate in the circular groove 415, and when the blocking block 412 moves between the blocking plate 416 and the circular groove 415, the screw 43 will not move in the L-shaped plate 41, so as to fix the screw 43 in the L-shaped plate 41, that is, when the molds of the island tail 3, the island body 1 and the island head 2 are mechanically lifted, the screw 43 will not be squeezed with the nut 42 in the L-shaped plate 41 under the action of gravity, which is beneficial to protect the screw 43 and store the screw 43 before and after use.
