Description

Technical Field

[0001] The present application belongs to the technical field of bridge crash barrier construction, and specifically relates to a reinforcement stabilization and positioning device suitable for crash barrier construction. Background Art

[0002] As a crucial structural component of a bridge, a crash barrier, constructed from reinforced concrete, serves to protect the bridge and also protect passing vehicles and pedestrians. During construction, the main reinforcement of the crash barrier needs to be connected to the main reinforcement of the bridge deck. This connection can be achieved through pre-embedded reinforcement or post-embedded reinforcement.

[0003] The early pre-embedding requires tying the main reinforcement of the crash wall to the bridge deck steel bars before the bridge deck is cast. The advantage of this method is that the crash wall is firmly connected to the bridge deck. The disadvantage is that holes need to be drilled in the formwork, which is not conducive to the removal of the formwork. At the same time, the pre-embedded steel bars are long, which will cause the steel bars to shift. The later planting of reinforcement requires drilling holes in the cast bridge deck. Since the bridge deck steel bars are dense and the hole positions are narrow, it is difficult to find the hole positions. Multiple drillings will cause certain damage to the bridge deck. At the same time, there are certain safety risks for workers to drill holes at the edge of the bridge. In response to the above problems, the present application provides a device for stabilizing and positioning planted reinforcement. Utility Model Content

[0020] Figure 2 This is a top view of the structure of this application (five sections).

[0021] Figure 3 This is the main view of the application structure.

[0022] In the figure: 1-first plate, 2-second plate, 3-third plate, 4-fourth plate, 5-fifth plate, 6-inner half hole, 7-outer half hole, 8-connecting screw, 9-locking nut, 10-enclosure support surface, 11-tension screw, 12-tension through hole. DETAILED DESCRIPTION

[0023] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0024] refer to Figures 1 to 3 As shown, a device for stabilizing and positioning rebars includes a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, a fifth plate 5, an inner half hole 6, an outer half hole 7, a connecting screw 8, a locking nut 9, a support surface 10, a tensioning screw 11, and a tensioning through hole 12. Each component needs to be processed in a factory and then transported to the site for assembly and use.

[0025] Each panel is a box-like structure assembled from steel plates, preferably a rectangular parallelepiped. This means the panel is constructed by welding together a top, bottom, and side panels, which are then assembled into a single panel. Semicircular holes are formed in the side panels based on the spacing and number of rebar to be implanted. Each panel has corresponding bolt holes, and bolts securely connect the components, preventing them from loosening during use and ensuring accurate and stable positioning of the rebar.

[0026] The second plate 2 and the third plate 3 are respectively arranged on the two outer sides of the first plate 1. The two outer sides of the first plate 1 are provided with inner half holes 6, and the inner sides of the second plate 2 and the third plate 3 are provided with outer half holes 7. The inner half holes 6 and the outer half holes 7 are arranged opposite to each other, so that the inner half holes 6 and the outer half holes 7 together constitute a channel for passing the steel bars. The three plates form two steel bar positioning structures in total.

[0027] Connecting screws 8 are fixed on both outer sides of the first plate 1, and the second plate 2 and the third plate 3 are sleeved on the connecting screws 8 in the horizontal inward and outward directions. The connecting screws 8 are threaded with locking nuts 9 located on the outer sides of the second plate 2 or the third plate 3. The second plate 2 and the third plate 3 are sleeved on the connecting screws 8, and the positions can be adjusted in the inward and outward directions to ensure the smooth passage of the steel bars. After the steel bars are passed through, the locking nuts 9 are tightened, and the plates clamp the steel bars to achieve overall fixation of the steel bars.

[0028] The lower end surfaces of the first plate 1, the second plate 2 and the third plate 3 are all enclosure support surfaces 10, and the enclosure support surfaces 10 are flat end surfaces, so that the device can be used as a template while positioning the steel bars.

[0029] Depending on the number of rebar positioning requirements, the number of plates can be increased based on the two-pass rebar positioning system to increase the number of rebar positioning paths. The fourth plate 4 is arranged outside the second plate 2, and the fifth plate 5 is arranged outside the third plate 3. The outer sides of the second and third plates 2 and 3 are each provided with an inner half-hole 6, and the inner sides of the fourth and fifth plates 4 and 5 are each provided with an outer half-hole 7. Thus, the inner half-hole 6 and the outer half-hole 7 together form a channel for the insertion of rebar. The five plates form a total of four rebar positioning paths.

[0030] The outer sides of the second and third panels 2 and 3 are fixed with connecting screws 8. The fourth and fifth panels 4 and 5 are sleeved horizontally on the connecting screws 8 in the inward and outward directions. The connecting screws 8 are threaded with locking nuts 9 located on the outer sides of the fourth and fifth panels 4 and 5, respectively. The lower end surfaces of the fourth and fifth panels 4 and 5 serve as enclosure support surfaces 10. The third and fourth panels are similar to the second and third panels and will not be described in detail here.

[0031] Four groups of inner half holes 6 and outer half holes 7 are arranged between two adjacent plates. The inner half holes 6 and the outer half holes 7 are all arc holes. Therefore, each steel bar positioning structure of the device can form four positioning holes, and the positioning holes are circular, which conforms to the cross-sectional shape of most steel bars.

[0032] The two ends and the middle of the plate are fixed with connecting screws 8. The connecting screws 8 can be directly bolts. The screw heads of the bolts are welded and fixed to the plate. The bolts at the two ends and the middle are used to connect the two plates. Tighten the locking nuts 9 to bring the two plates close together, and then tighten the steel bars to fix them.

[0033] For situations with more than three panels, using limited-length screws is inconvenient. Instead, a tensioning hole 12 is provided in the middle of each panel. A tensioning screw 11 is passed through the tensioning hole 12 horizontally inward and outward. Locking nuts 9 are located on the outside of the outermost panel at both ends of the tensioning screw 11. This allows all bolts in the middle to be replaced using a single tensioning screw 11, making replacement simpler and more convenient.

[0034] The workflow of this application:

[0035] 1. The plate is customized with appropriate length and width according to the size of the casting surface, and is made into top plate, side plate and bottom plate respectively. Semicircular holes are formed in the side plate according to the spacing and number of implanted steel bars. The top plate, side plate and bottom plate are assembled into a plate component, and each plate component has corresponding bolt holes.

[0036] 2. Transport the processed plate components to the site and assemble them on site. The plate components are preliminarily connected with bolts to form a whole.

[0037] 3. Place the device at the rebar planting position and fix it to the side formwork. After the rebar is vertically inserted through the hole, tighten the bolts of the device to ensure the stability of the rebar, and finally pour the bridge deck concrete.

[0038] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
