[0002] During the construction of precast culverts, the thickness and length of the cover plate vary depending on the culvert diameter. When tying and installing the reinforcing bars for the culvert cover plate, manual measurement or the use of traditional rebar tying jigs is typically employed for positioning and fixing the bars. Using manual measurement directly requires a large labor input, and the construction quality cannot be guaranteed. Using traditional rebar tying jigs for installation requires fabricating jigs of different sizes for different culvert cover plate dimensions, which is both time-consuming and wasteful of materials.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] In the construction of precast culverts, the width of the cover slab is typically 1m, while its thickness and length are determined by the specific project requirements. Regarding the reinforcement arrangement, continuous main reinforcing bars are provided along the length of the cover slab, both on the top and bottom surfaces; stirrups are provided along the width. Therefore, the height difference between the main reinforcing bars on the top and bottom surfaces varies in cover slabs of different sizes, and the total length of the main reinforcing bars at the same height also differs.

[0030] This utility model provides a rebar tying frame for culvert covers, with adjustable positioning dimensions in both the height and length directions. Therefore, for cover plates of different manufacturing sizes, the rebar tying frame can provide positioning and fixing functions for the tying and installation of the main reinforcing bars. The rebar tying frame includes a first mounting component, a second mounting component, a support component, and a horizontal positioning component. The following description, in conjunction with the accompanying drawings, details each component.

[0031] like Figure 1 and Figure 2 As shown, in this preferred embodiment, the first mounting member is an upper angle steel 1, and the second mounting member is a lower angle steel 2. Both the upper angle steel 1 and the lower angle steel 2 have one leg pointing vertically upwards and the other leg pointing horizontally. At the top of the vertical leg of the upper angle steel 1, a plurality of first limiting grooves 11 are provided along the length direction, with equal spacing and upward-facing openings. Similarly, at the top of the vertical leg of the lower angle steel 2, a plurality of second limiting grooves 21 are provided along the length direction, with the same features as the first limiting grooves 11. In this preferred embodiment, the distance between the first limiting grooves 11 and the second limiting grooves 21 is 100mm. As a simple alternative to this embodiment, the first mounting member can also be a single steel plate, with the same arrangement as the vertical leg of the upper angle steel 1.

[0032] like Figure 1As shown, in this preferred embodiment, two vertical support members 3 are symmetrically arranged in a set of reinforcing bar installation surfaces. Each support member 3 consists of two first flat steel bars 31 and two sets of first bolt assemblies 32. A first clearance groove 311 is provided along the length direction of the first flat steel bar 31, and the first clearance groove 311 extends through the thickness direction. The width of the first clearance groove 311 is greater than the diameter of the threaded rod in the first bolt assembly 32, but smaller than the outer dimensions of the nut and bolt head. When the two first flat steel bars 31 partially overlap in the thickness direction, a section of the first clearance groove 311 also overlaps. Two sets of first bolt assemblies 32 are spaced apart within the overlapping first clearance grooves 311. When neither of the first bolt assemblies 32 is tightened, the two first flat steel bars 31 can move relative to each other in the length direction; when both of the first bolt assemblies 32 are tightened, the relative movement between the two first flat steel bars 31 is restricted. Therefore, the two first flat steel bars 31 cooperate with the first bolt assembly 32 to control the expansion and contraction and fixation of the support member 3 in the vertical direction.

[0033] like Figure 3 As shown, in this preferred embodiment, a set of the rebar binding jigs is symmetrically provided with two sets of the horizontal positioning members 4. Combined with... Figure 2 and Figure 3 The horizontal positioning component 4 is configured similarly to the support component 3. The horizontal positioning component 4 consists of two second flat steel bars 41 and two sets of second bolt assemblies 42. Several second clearance grooves 411 are provided along the length direction of the second flat steel bars 41, and these grooves extend through the thickness direction. The specifications of the second bolt assemblies 42 are the same as those of the first bolt assemblies 32, therefore the width of the second clearance grooves 411 is consistent with that of the first clearance grooves 311. Similarly, when the two second flat steel bars 41 partially overlap in the thickness direction, the two sets of second bolt assemblies 42 are spaced apart and inserted into the overlapping second clearance grooves 411. When neither of the second bolt assemblies 42 is tightened, the two second flat steel bars 41 can move relative to each other in the length direction; when both second bolt assemblies 42 are tightened, the relative movement between the two second flat steel bars 41 is restricted. Therefore, the two second flat steel bars 41 and the second bolt assemblies 42 cooperate with each other to control the horizontal expansion, contraction, and fixation of the horizontal positioning component 4.

[0034] Both the support member 3 and the horizontal positioning member 4 are telescopic structures, and their specific arrangement is not limited to that described in this preferred embodiment. In other specific embodiments: two pipe sections with the same cross-sectional type can be interlocked, and a limiting member can be provided in the interlocking section to control the two pipe sections to be in a movable or fixed state in the length direction; alternatively, a reversing mechanism can be provided between the two coaxial pipe sections, and by rotating the reversing mechanism, the two pipe sections can be moved apart or toward each other in the length direction; and so on. The number of support members 3 or horizontal positioning members 4 is also not limited to this preferred embodiment. In particular, when the number of support members 3 or horizontal positioning members 4 is only one set, stiffening ribs need to be provided at the ends to enhance the stability of the frame.

[0035] Combination Figures 1-3 The connection relationships between the various components of the rebar tying frame are described in detail below. Two support members 3 are vertically arranged; in each support member 3, the upper section of the first flat steel 31 is welded to the vertical leg of the upper angle steel 1, and the lower section of the first flat steel 31 is welded to the vertical leg of the lower angle steel 2. The two support members 3, the upper angle steel 1, and the lower angle steel 2 form a set of rebar mounting surfaces. The two sets of rebar mounting surfaces are arranged facing each other and connected as a whole by two symmetrically arranged horizontal positioning members 4. Specifically, the two ends of each horizontal positioning member 4 are connected to the horizontal leg of the lower angle steel 2, and a clearance through hole is provided at the connection point. A set of third bolt assemblies 5 are inserted through the clearance through hole for fixation. The horizontal positioning members 4 and the lower angle steel 2 are perpendicular to each other.

[0036] During the binding and installation of the auxiliary cover plate reinforcement, loosen all the first bolt assemblies 32 on the support member 3, adjust the height of the upper angle steel 1 so that the height difference between it and the lower angle steel 2 conforms to the layer spacing between the main reinforcement bars on the slab surface and the main reinforcement bars at the bottom of the slab in the design drawings, and then tighten all the first bolt assemblies 32 to complete the adjustment of the positioning dimension of the reinforcement binding frame in the height direction. Loosen all the second bolt assemblies 42 on the horizontal positioning member 4, adjust the length of the horizontal positioning member 4 so that the interval between the two sets of reinforcement installation surfaces meets the construction requirements, and then tighten all the second bolt assemblies 42 to complete the adjustment of the positioning dimension of the reinforcement binding frame in the height direction. After the reinforcement binding and installation process of the culvert cover plate is completed, remove each set of bolt assemblies, and then take out the separated flat steel and angle steel parts to complete the disassembly of the frame.

[0037] To make the adjustment and positioning of the rebar tying jig more precise and convenient, dimensional scales can be provided on the surfaces of the support member 3 and the horizontal positioning member 4. Taking the support member 3 as an example, a set of dimensional scales is provided along the entire length of both first flat steel bars 31. The two sets of dimensional scales are independent of each other and are set towards each other. That is, the starting point of the scale on the upper section of the first flat steel bar 31 is the connection point with the upper angle steel 1, and the starting point of the scale on the lower section of the first flat steel bar 31 is the connection point with the lower angle steel 2. The dimensional scales on the surface of the horizontal positioning member 4 are set in the same way as those on the support member 3, with the starting point of each set of dimensional scales being the connection point between the second flat steel bar 41 and the rebar mounting surface.

[0038] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
