[0036] See also Fig.10 , the first superposition mode of the perforated paving steel plates 1: the long sides of the perforated paving steel plates 1 are superimposed and connected with the corresponding long sides of the adjacent perforated paving steel plates 1;

[0037] See also Fig.11 The second stacking method of the perforated paving steel plates 1 is as follows: the long sides of the two perforated paving steel plates 1 are connected side by side, and the short sides of the two perforated paving steel plates 1 connected side by side are stacked and connected with the long side of the third perforated paving steel plate 1 up and down.

[0038] The utility model discloses a paving steel plate connection assembly for the earthwork transportation stage of construction, which is realized by the following structure: a paving steel plate 1 with holes having standardized regular openings, a steel pin part 2, a steel insert part 3, and a prefabricated locking pin 4. The paving steel plate 1 with holes having standardized regular openings is a paving steel plate with simple holes drilled according to the design positioning requirements, so as to realize different arrangements and combinations of the paving steel plate 1 with holes. The steel pin part 2 has a base 21 of a circular thick plate at the bottom, a square columnar pin 22 at the top, a semicircular arc at the end of the pin 22, and a circular through hole 23 at the head of the pin 22. The steel insert part 3 has a semicircular thick cover body 32 at the top, a steel sealing plate 31 is arranged on one side, a cylindrical latch rod 33 is arranged at the center of the sealing plate 31, and a circular locking hole 34 is opened at the rod end. The body of the prefabricated locking pin 4 is cylindrical, and one end of the prefabricated locking pin 4 is bent and expanded.

[0039] The utility model discloses an installation process of a paving steel plate connection assembly used in the earthwork transportation stage of construction, which requires the use of a paving steel plate 1 with holes having standardized regular openings, a steel pin part 2, a steel insert part 3, and a prefabricated locking pin 4.

[0040] First, we select the paving steel plates (2 meters wide and 4 meters long) with the specifications commonly used in the current engineering field, and make holes according to the design positioning shown in the diagram. The hole diameter is 100mm, and the holes are equidistant from the edge of the steel plate. The holes are made uniformly according to the design rules, which can form a standardized processing process and be completed in batches. At the same time, the paving steel plates can be flexibly combined in different ways during the later use process, which provides convenience for practical applications.

[0041] like Fig.12 As shown, in the first step, the front block (lower layer) perforated paving steel plate 1 is transported to the intended paving position by a machine (not shown in the figure) and placed in place before landing. The side position of the intended connection of the rear block (upper layer) perforated paving steel plate 1 is first determined on the front block (lower layer) perforated paving steel plate 1, and the pin member 2 (including the base 21 and the pin 22) is pre-through the opening of the side position of the intended connection of the rear block (upper layer) perforated paving steel plate 1 on the front block (lower layer) perforated paving steel plate 1. Then, the insert member 3 (including the semicircular cover body 32, the sealing plate 31, and the latch rod 33) is temporarily assembled to the perforated pin member 2, and the front block (lower layer) perforated paving steel plate 1 is placed on the front block (lower layer) perforated paving steel plate 1. When the perforated paving steel plate 1 is put on the ground, the pin member 2 is accurately positioned at one time, and the pin member 2 and the insert member 3 are temporarily assembled in advance, so as to avoid repeated adjustments for accurately placing the pin member 2 and aligning it with the opening position of the front block (lower layer) perforated paving steel plate 1 during the landing process, and avoid the potential safety hazards caused by manual repeated adjustments in the process of synchronously placing the pin member 2 in the hole alignment process when the front block (lower layer) perforated paving steel plate 1 is in place, and can greatly improve the efficiency of steel plate laying. At the same time, this method fully utilizes the existing supporting parts, and there is no need to increase the cost of temporary fixing measures for the pin member 2.

[0042] The opening diameter of the perforated paving steel plate 1 is 100 mm, and the perforated part of the pin member 2 is a square with a side length of 60 mm. The space reserved in the size design of the two can provide convenience for the perforated installation of the pin member 2, and at the same time provide a fault tolerance space for the local deformation of the opening on the perforated paving steel plate 1, thereby expanding the adaptability of the installation of the connection assembly.

[0043] When the front (lower layer) perforated paving steel plate 1 is in place and landed, the latch member 3 of the connecting mechanism is removed.

[0044] In the second step, the rear block (upper layer) perforated paving steel plate 1 is transported to the intended paving position by machinery, and the hole center of the intended connecting section is aligned with the pin part 2 that has been placed in place on the front block (lower layer) perforated paving steel plate 1, and then it is put into place and stacked on the front block (lower layer) perforated paving steel plate 1.

[0045] The opening diameter of the perforated paving steel plate 1 is 100 mm, and the diameter of the perforated part of the pin member 2 is 60 mm. The space reserved in the size design of the two can effectively reduce the accuracy requirement for placing the rear block (upper layer) perforated paving steel plate 1 and improve the paving efficiency.

[0046] After the front and rear perforated paving steel plates 1 are stacked and laid, the insert 3 is aligned with the through hole 23 where the pin 2 is placed and pushed in horizontally.

[0047] The top cover 32 of the insert 3 is designed in an arc shape, which can effectively prevent the tires of the mechanical equipment running above from being damaged and accidents, and provide comprehensive safety protection; at the same time, the reasonable arc height design can provide anti-slip points for the steel plate of the cover 32; and the end of the square columnar pin 22 in the pin member 2 is designed as an arc cylinder, which matches the arc-shaped cover 32 design of the top of the insert 3, so that the pin member 2 provides a sufficiently flexible contact surface for the insert 3, which can provide stable protection for the operation of the mechanical equipment running above;

[0048] In the third step, the locking pin 4 is finally passed through the locking hole 34 reserved on the insert 3. This ensures that the connection assembly is firmly connected during use.

[0049] According to the needs of temporary road paving, in the case of several perforated paving steel plates 1 being connected later, it is only necessary to completely repeat the above process before the previous (lower layer) perforated paving steel plate 1 is put into place and landed to achieve any length requirement. The above standardized operation process can accurately calculate the amount of materials required for temporary road paving and improve the paving efficiency.

[0050] When the temporary road is finished and needs to be dismantled, it can be disassembled in the reverse order of the above installation process, first remove the locking pin 4, then remove the insert 3, remove the front and rear perforated paving steel plates 1, and finally recycle the pin 2. All parts of the connection assembly can be recycled, and at the same time, they are easy to classify and reuse, which can realize the concept of environmental protection.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0052] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
