Description

Technical Field

[0001] This utility model relates to the field of rebar tying technology, specifically to a rebar tying frame for the side wall of a culvert. Background Technology

[0002] A slab culvert is a structure consisting of a slab cover, abutment cap, culvert abutment, foundation, and expansion joints. It is primarily used for drainage and flood control. Slab culverts are required in bridge and tunnel engineering. During the precast concrete sidewall construction of slab culverts, steel reinforcement cages are needed for binding, thus requiring a special steel reinforcement binding frame for the slab culvert sidewalls.

[0003] Most existing slab culverts use U-shaped top slabs with side wall heights of 1-2m. The steel reinforcement cages can be vertically tied. However, some slab culverts use straight slabs and higher side wall designs, with side wall heights of 4-5m.

[0004] When the height of the culvert is relatively high, vertical binding is used. Workers need to frequently go up and down the platform to bind the upper layer of steel bars, which is extremely inconvenient and has low binding efficiency. Moreover, it is a high-altitude operation with great safety hazards. Therefore, we propose a culvert side wall steel bar binding frame. Utility Model Content

[0005] The purpose of this utility model is to provide a tying frame for the side wall reinforcement of a culvert, in order to solve the problems mentioned in the background art, which are that due to the high height of the culvert, vertical tying is used, and workers need to frequently go up and down the platform to tie the upper layer of reinforcement, which is extremely inconvenient, has low tying efficiency, and poses a great safety hazard as it is a high-altitude operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a culvert sidewall reinforcement binding frame, comprising:

[0007] The base has a main frame installed on both sides, and a first connecting crossbar is installed on the main frame. The first connecting crossbar is provided with longitudinal limiting teeth.

[0008] A binding base plate is provided on the outside of the main frame. A binding middle rod is connected to the top of the main frame, and a second connecting crossbar is connected to one end of the binding middle rod. A top rod is provided above the second connecting crossbar, and lateral limiting teeth are provided on one side of the inner wall of the top rod, the second connecting crossbar, and the binding middle rod.

[0009] A positioning seat is connected to one end of the base, and a limit baffle is installed on the positioning seat.

[0010] Preferably, the main frame and the binding base plate are symmetrically distributed about the vertical center line of the base, and the lateral limiting teeth are evenly distributed along one end of the binding base plate. The main frame and the binding base plate are welded to the base respectively.

[0011] Preferably, the main frame is fixedly connected to the binding middle rod, and the second connecting crossbar is fixedly connected to the binding middle rod, and the lateral limiting teeth are evenly distributed along the inner walls of the binding middle rod and the second connecting crossbar.

[0012] Preferably, the transverse limiting teeth are symmetrically distributed about the vertical center line of the push rod, and the push rod corresponds to the position of the second connecting crossbar.

[0013] Preferably, the first connecting crossbar is symmetrically distributed about the vertical center line of the base, and the longitudinal limiting teeth are equidistantly distributed along the upper end surface of the first connecting crossbar.

[0014] Preferably, the limiting baffle is perpendicular to the positioning seat, and the position of the limiting baffle corresponds to the position of the longitudinal limiting teeth.

[0015] Preferably, the limiting baffle further includes:

[0016] A nut conveying block is connected to both ends below the limiting baffle. A threaded screw is installed inside the nut conveying block, and one end of the threaded screw is connected to a drive motor.

[0017] Compared with the prior art, this utility model provides a tying frame for the side wall reinforcement of a culvert, which has the following beneficial effects:

[0018] This invention utilizes transverse limiting teeth on the binding base plate, binding middle rod, second connecting crossbar, and top rod to engage with longitudinal limiting teeth on the first connecting crossbar. This facilitates the staggered arrangement of reinforcing bars, enabling precise positioning of the bars and ensuring the quality of the reinforcing cage. It also allows for horizontal binding of side wall reinforcing bars, enabling workers to operate from the ground without climbing a binding platform. This improves binding efficiency and enhances safety, avoiding the problems associated with vertical binding in high-height culverts where workers frequently need to climb up and down platforms to bind upper reinforcing bars, resulting in inconvenience, low efficiency, and significant safety hazards due to the high-altitude nature of the work.

The first connecting horizontal bar 5 is symmetrically distributed about the vertical center line of the base 1, and the longitudinal limiting teeth 6 are equidistantly distributed along the upper end face of the first connecting horizontal bar 5. The lateral limiting teeth 9 on the binding base plate 3, binding center bar 4, second connecting horizontal bar 7 and top bar 8 can cooperate with the longitudinal limiting teeth 6 on the first connecting horizontal bar 5, which facilitates the staggered arrangement of the reinforcing bars, thereby achieving precise positioning of the reinforcing bars, ensuring the quality level of the reinforcing cage, and facilitating the horizontal binding of the side wall reinforcing bars.

[0026] Please see Figure 1 , 34. A culvert sidewall reinforcement binding frame, comprising: a positioning seat 10 connected to one end of a base 1, wherein a limiting baffle 11 is installed on the positioning seat 10; the limiting baffle 11 is perpendicular to the positioning seat 10 and corresponds to the position of the longitudinal limiting teeth 6; the limiting baffle 11 can limit the starting position of the transverse reinforcement to prevent the reinforcement from shifting and affecting the quality of the reinforcement cage; a nut conveying block 12 connected to both ends below the limiting baffle 11, wherein a threaded rod 13 is installed inside the nut conveying block 12, and one end of the threaded rod 13 is connected to a drive motor 14; the drive motor 14 can drive the threaded rod 13 to rotate, and the rotating threaded rod 13 can horizontally convey the nut conveying block 12 and the limiting baffle 11, thereby facilitating the adjustment of the starting position according to the length of the reinforcement.

[0027] Working Principle: When using this culvert sidewall rebar tying jig, the rebars are first placed into the teeth according to the horizontal and vertical arrangement of the limiting teeth. The horizontal limiting teeth 9 on the tying base plate 3, tying middle rod 4, second connecting crossbar 7, and top rod 8 can cooperate with the vertical limiting teeth 6 on the first connecting crossbar 5 to facilitate the staggered arrangement of the rebars, thereby achieving precise positioning of the rebars and ensuring the quality level of the rebar cage.

The rotating threaded screw 13 can horizontally transmit the nut conveying block 12 and the limiting baffle 11, thereby facilitating the adjustment of the starting position according to the length of the rebar. The limiting baffle 11 can limit the starting position of the horizontal rebars to prevent the rebars from shifting and affecting the quality of the rebar cage. The tying jig facilitates horizontal tying of the sidewall rebars, allowing workers to work on the ground without climbing the tying platform, improving tying efficiency and enhancing safety. This is the working principle of the culvert sidewall rebar tying jig.
