Description

Technical Field

[0001] The utility model belongs to the technical field of precast component production, and particularly relates to a double steel mold for a Jersey barrier with one - drag - two structure. Background Art

[0002] The Jersey barrier is a wall - type barrier with a certain cross - section shape and is used for highway isolation. The Jersey barriers are all precast on the production site and then transported to the construction site for installation. In the production line of the Jersey barrier, steel molds of corresponding models need to be configured. Concrete is poured into the steel mold, and then it is leveled, steam - oxygenated, flipped, demolded, etc., and finally the finished precast component of the Jersey barrier is obtained.

[0003] At present, the steel molds of the Jersey barrier are all single - mold structures. Not only is the production efficiency low, but also due to the uneven weight distribution of the Jersey barrier, one side is thicker and the other side is thinner, so the center of gravity of the steel mold is unstable during transmission on the transmission line, and the heavier side wears more. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a double steel mold for a Jersey barrier with one - drag - two structure, aiming to solve the above - mentioned technical problems.

[0005] The utility model adopts the following technical solutions:

[0006] The double steel mold for a Jersey barrier with one - drag - two structure includes a rectangular chassis. Side plates are rotatably installed around the chassis, and adjacent side plates are locked through a locking structure. A shaping template is covered on the chassis, and the middle of the shaping template bulges upward, and two barrier positions are formed on both sides.

[0007] Further, the chassis includes a laterally - fixed steel beam and a longitudinally - fixed steel beam which are integrally fixed. A plurality of support rib plates matching the bottom shape of the shaping template are arranged on the laterally - fixed steel beams.

[0008] Further, there are grooves on the support rib plates, and brackets are placed on the grooves.

[0009] Further, the inner side of the barrier position is higher and the outer side is lower.

[0010] Further, the locking structure includes a rotating plate rotatably installed at the top corner position of one side plate, and also includes a positioning pin fixed to the adjacent side plate. The head end of the rotating plate has a guiding edge, and the lower edge has a notch. A tension spring is also arranged in the middle of the rotating plate.

[0011] Further, there is also a protective cover on the side plate where the rotating plate is installed, and the rear half of the rotating plate and the tension spring are located inside the protective cover.

[0012] The beneficial effects of the present utility model are as follows: In this structure, the double steel mold is a two-position structure with one for two, and is symmetrically arranged along the axis. Two New Jersey guardrails can be produced at one time. Moreover, the width of the double steel film exactly matches the spacing of the transmission line, and the existing transmission line can be used, improving the equipment utilization rate. In addition, the double steel mold is symmetric left and right. After concrete is arranged inside, the center of gravity is still at the center of gravity position of the steel mold, so the uneven wear of the transmission line will not occur.

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0019] As Figures 1-4 shown, the two-for-one New Jersey guardrail double steel mold provided by this embodiment includes a rectangular chassis 1. Side plates 3 are rotatably installed around the chassis 1. Among them, adjacent side plates 3 are locked by a locking structure 4. A shaping template 5 is covered on the chassis 1. The middle of the shaping template 5 bulges upward, and two guardrail positions 2 are formed on both sides.

[0020] In this structure, there are two guardrail positions on the steel mold and they are symmetrically arranged. After concrete is arranged inside the steel mold, the center of gravity is still at the center of gravity position of the steel mold, so the uneven wear of the transmission line will not occur. In the figure, the inner side position of the guardrail position of the steel mold is high and the outer side position is low, and the weight is concentrated on the outer side, above the transmission line. Due to the double steel mold structure design, there are two guardrail positions, and two New Jersey guardrails can be produced at one time. Moreover, the width of the double steel film exactly matches the spacing of the transmission line, and the existing transmission line can be used, improving the equipment utilization rate.

[0021] As a specific structure of the chassis, as shown in combination with Figure 2 , 4 The chassis 1 includes a laterally disposed steel beam 11 and a longitudinally disposed steel beam 12 that are integrally fixed. The two ends of the laterally disposed steel beam are welded between a pair of longitudinally disposed steel beams. Both types of steel beams are made of channel steel, ensuring the overall firmness. In addition, support rib plates 13 that match the shape of the bottom of the sizing template 5 are provided on some of the laterally disposed steel beams 11. The support rib plates 13 are used to support the shape of the sizing template 5 and prevent it from deforming.

[0022] Furthermore, since the precast concrete member is heavy, there are grooves 14 on the support rib plates 13, and brackets 15 are placed on the grooves 14. Through the design of the brackets 15, further support for the bottom of the sizing template 5 is formed.

[0023] The side plates of the steel form are connected by a locking structure 4. The locking structure 4 includes a rotating plate 41 rotatably installed at the top corner position of one side plate, and also includes a positioning pin 42 fixed to the adjacent side plate. The head end of the rotating plate 41 has a guiding edge 43, and the lower edge has a notch 44. A tension spring 45 is also provided in the middle of the rotating plate 41. Under the pulling force of the spring 45, the rotating plate 41 has a tendency to rotate downward. The positioning pin 42 is a T-shaped structure, and the notch 44 at the lower edge of the rotating plate is stuck on the positioning pin 42. The tension spring can prevent the rotating plate from rotating back, ensuring stability. After the New Jersey guardrail is hardened, the form is removed. By rotating the head end of the rotating plate upward, the notch is disengaged from the positioning pin, and the unlocking can be completed. The side plate is flipped downward to complete the form removal.

[0024] In addition, there is a protective cover 46 on the side plate where the rotating plate 41 is installed. The rear half of the rotating plate 41 and the tension spring 45 are located inside the protective cover 46. The function of the protective cover 46 is to prevent accidental contact with the spring, rotating plate, etc.

[0025] In this structure, the transmission line includes a fixed roller assembly 61 and a power roller assembly 62. The power roller assembly 62 includes a bottom plate 621. A bearing plate 622 is rotatably provided on one side of the bottom plate 621. A power motor 623 is installed on the bearing plate 622. There is a driving wheel on the output shaft of the power motor 526. A spring pressure rod 624 is rotatably provided on the other side of the bottom plate 621. The bearing plate 622 has a U-shaped opening and the U-shaped opening is installed on the spring pressure rod 624. Under the action of the spring pressure rod, the power motor has a tendency to rotate upward, which can ensure that the driving wheel is in close contact with the bottom plate of the steel form and improve the driving effect.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
