Description

Technical Field

[0001] This application relates to the technical field of steel bar verticality adjustment, and particularly to a steel bar verticality adjustment device for precast reinforced concrete anti-collision guardrails. Background Art

[0002] A precast concrete anti-collision guardrail is a reinforced concrete component that is prefabricated in a factory and directly assembled on-site later. Compared with the traditional method of casting concrete on-site, the precast concrete anti-collision guardrail has higher engineering quality, construction efficiency, and environmental friendliness. A precast concrete anti-collision guardrail is composed of a steel bar skeleton and concrete casting. When the steel bar skeleton is impacted by concrete during casting, it is prone to skew, affecting the stability of the concrete component. Therefore, a steel bar verticality adjustment device for precast reinforced concrete anti-collision guardrails is proposed. Utility Model Content

[0003] In order to solve the problem that the steel bar skeleton is prone to skew when impacted by concrete during casting, affecting the stability of the concrete component, this application provides a steel bar verticality adjustment device for precast reinforced concrete anti-collision guardrails.

[0004] The steel bar verticality adjustment device for precast reinforced concrete anti-collision guardrails provided by this application adopts the following technical solutions:

[0005] The steel bar verticality adjustment device for precast reinforced concrete anti-collision guardrails includes a steel bar and a casting formwork mechanism. Multiple groups of steel bars are provided and connected to each other by bundling. The multiple groups of steel bars are evenly distributed. The steel bars are arranged inside the casting formwork mechanism. Multiple groups of slots are formed in the middle of the side wall of the casting formwork mechanism. One group of slots corresponds to one group of steel bars. Each group of slots has two and is located on both sides of the steel bar. Positioning plates are installed in each slot in a matching manner and form a moving pair with it. The positioning plates can move into the casting formwork mechanism through the slots to position the steel bars.

[0006] Preferably, the casting formwork mechanism includes a bottom plate, side plates, a front guard plate, and a rear guard plate. Two groups of side plates are symmetrically and fixedly installed on both sides of the upper surface of the bottom plate. The front guard plate and the rear guard plate are both arranged between the two groups of side plates, and the front guard plate and the rear guard plate are both connected to the bottom plate and the side plates by setting first bolts. The bottom plate, side plates, front guard plate, and rear guard plate form a casting cavity with an upward opening.

[0007] Preferably, the slots are all formed in the middle of the outer surface of the front guard plate.

[0008] Preferably, one end of the positioning plates located outside the casting cavity is commonly and fixedly connected with a connecting plate.

[0009] Preferably, the four corners of the connecting plate are connected to the front guard plate by inserting second bolts, and a handle is fixedly connected to the outer surface of the connecting plate.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] The utility model adopts a method of pouring in batches to manufacture a concrete anti-collision guardrail. During the first pouring, the steel bars are restricted by setting positioning plates to keep the steel bars vertical and prevent the steel bars from skewing during the pouring process. When the concrete poured for the first time solidifies, at this time, the bottom of the steel bars is fixed by the concrete, and the positioning plates can be removed from the slots, and then the subsequent pouring can be continued. Therefore, the utility model can ensure that the steel bars remain perpendicular throughout the pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further describes the present application in detail Figures 1-5 with reference to the accompanying drawings.

[0019] The embodiment of the present application discloses a device for adjusting the perpendicularity of steel bars for an assembled reinforced concrete anti-collision guardrail, including steel bars 5 and a pouring formwork mechanism. Multiple groups of steel bars 5 are provided and connected to each other by bundling. Multiple groups of steel bars 5 are equidistantly distributed. The steel bars 5 are arranged inside the pouring formwork mechanism. Multiple groups of slots 7 are provided in the middle of the side wall of the pouring formwork mechanism. One group of slots 7 corresponds to one group of steel bars 5. Each group of slots 7 has two and is located on both sides of the steel bars 5. Positioning plates 9 are installed in the slots 7 in a matching manner and form a moving pair with them. The positioning plates 9 can move into the pouring formwork mechanism through the slots 7 to position the steel bars 5.

[0020] Furthermore, the pouring formwork mechanism includes a bottom plate 1, side plates 2, a front guard plate 3 and a rear guard plate 4. There are two groups of side plates 2 which are symmetrically and fixedly installed on both sides of the upper surface of the bottom plate 1. Both the front guard plate 3 and the rear guard plate 4 are arranged between the two groups of side plates 2, and both the front guard plate 3 and the rear guard plate 4 are connected to the bottom plate 1 and the side plates 2 by setting first bolts 6. The bottom plate 1, the side plates 2, the front guard plate 3 and the rear guard plate 4 form a pouring mold cavity with an upward opening.

[0021] Furthermore, the slots 7 are all opened at the middle of the outer surface of the front guard plate 3.

[0022] In this embodiment, in order to maintain the perpendicularity of the steel bars 5, the concrete anti-collision guardrail is manufactured by means of pouring in batches. Before pouring, the pre-bundled steel bars 5 are placed inside the pouring mold cavity, and the corresponding positioning plates 9 are inserted into the pouring mold cavity through the slots 7. Each group of positioning plates 9 can restrict the steel bars 5 inside it to keep them in a vertical state and prevent the steel bars 5 from skewing during the pouring process. When pouring for the first time, it is necessary to ensure that the height of the concrete in the pouring mold cavity is lower than the lower surface of the positioning plate 9. When the concrete poured for the first time solidifies, at this time, the bottom of the steel bars 5 is fixed by the concrete, and the positioning plates 9 can be removed from the slots 7, and then the subsequent pouring can be continued. It should be noted that during the first pouring process, it is necessary to pay attention to making the outlet of the concrete pouring pipe lower than the positioning plate 9 to prevent the positioning plate 9 from adhering to the concrete and ensure its smooth movement in the slot 7.

[0023] Specifically, the shape of the pouring mold cavity formed by the bottom plate 1, the side plates 2, the front guard plate 3 and the rear guard plate 4 is set according to specific needs. Since the front guard plate 3 and the rear guard plate 4 are connected to the bottom plate 1 and the side plates 2 by setting first bolts 6, the front guard plate 3 and the rear guard plate 4 are detachable relative to the bottom plate 1 and the side plates 2, so as to facilitate the subsequent removal of the anti-collision guardrail.

[0024] Furthermore, one ends of the positioning plates 9 located outside the pouring mold cavity are fixedly connected together with a connecting plate 8.

[0025] Furthermore, the four corners of the connecting plate 8 are connected to the front guard plate 3 by inserting second bolts 11, and a handle 10 is fixedly connected to the outer surface of the connecting plate 8.

[0026] In this embodiment, by setting the connecting plate 8 and the handle 10, the connecting plate 8 and all the positioning plates 9 can be moved by moving the handle 10, and by setting the second bolts 11, during pouring, the second bolts 11 are used to connect the front guard plate 3 and the connecting plate 8, which can ensure the stability of the positioning plates 9.
