Description

Technical Field

[0001] This utility model mainly relates to the field of steel reinforcement construction technology, and in particular to a longitudinal steel reinforcement positioning bracket. Background Technology

[0002] Secondary lining (abbreviated as "secondary lining") is a commonly used term in tunnel engineering construction. It refers to the reinforced concrete lining constructed inside the initial support. Its purpose is to form a composite lining together with the initial support to achieve the function of reinforcing the support and thus meet the requirements of modern tunnel construction.

[0003] Secondary lining includes reinforcement construction, which involves binding to form an arched reinforcement cage that conforms to the shape of the tunnel wall. The reinforcement cage of the secondary lining is formed by circumferential and longitudinal reinforcement arranged in a "well" pattern. The circumferential reinforcement is arched. During reinforcement construction, the two ends of the circumferential reinforcement are usually connected to the pre-embedded inverted arch reinforcement to form a preliminary fixation. Then, the longitudinal reinforcement is tied to the circumferential reinforcement to form a reinforcement mesh.

[0004] In existing technologies, to determine the spacing of longitudinal reinforcing bars, workers typically first use measuring tools to measure and mark the circumferential reinforcing bars, and then arrange the longitudinal reinforcing bars in the corresponding positions according to the marks. This method is not only complex to operate, but the marks are also easily destroyed during construction, making it difficult to guarantee construction efficiency and accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a longitudinal steel bar positioning bracket.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A longitudinal rebar positioning bracket includes a positioning rod, one end of which is provided with a fixing mechanism I for connecting the tied longitudinal rebar, and the other end of which is provided with a fixing mechanism II for connecting the transverse rebar; the positioning rod is also provided with a plurality of limiting slots for fixing the untied longitudinal rebar at equal intervals.

[0008] One end of the positioning rod is equipped with a fixing mechanism one for connecting the tied longitudinal reinforcing bars, and the other end is equipped with a fixing mechanism two for connecting the transverse reinforcing bars. Using fixing mechanisms one and two, the positioning rod can be quickly fixed and installed, and positioned using the tied longitudinal reinforcing bars. Once the positioning rod is positioned relative to the tied longitudinal reinforcing bars via fixing mechanism one, the positions of the evenly spaced limiting slots on the positioning rod are also determined. When the operator places the untied longitudinal reinforcing bars into the limiting slots, the position of the longitudinal reinforcing bars is determined, thus enabling the rapid arrangement of untied longitudinal reinforcing bars. This method eliminates the steps of measuring with a ruler and marking on the circumferential reinforcing bars, thereby reducing the difficulty of manual positioning operations and improving construction efficiency. Simultaneously, it effectively prevents the markings from being damaged during construction, leading to incorrect positioning and thus improving construction accuracy.

[0009] In the aforementioned longitudinal reinforcement positioning bracket, preferably, the positioning rod is bent, and its curvature is consistent with that of the transverse reinforcement.

[0010] The positioning rod is bent, and its curvature is consistent with that of the transverse reinforcement. This ensures that the untied longitudinal reinforcement placed on it can be placed on the transverse reinforcement, thus facilitating the subsequent tying operation.

[0011] In the aforementioned longitudinal rebar positioning bracket, preferably, the fixing mechanism is configured as a buckle with its opening facing downwards; the limiting slots all open upwards.

[0012] By designing the fixing mechanism as a downward-opening buckle structure, the positioning bracket can be securely attached simply by placing the fixing mechanism on the tied longitudinal reinforcing bars, thus simplifying the operation. Similarly, by designing the limiting slot as an upward-opening structure, untied longitudinal reinforcing bars can easily enter the slot from top to bottom and rest on the transverse reinforcing bars, also simplifying the operation.

[0013] In the aforementioned longitudinal rebar positioning bracket, preferably, the fixing mechanism two includes a support rod one perpendicular to the positioning rod, the end of the support rod one facing away from the positioning rod having a first slot for connecting transverse rebars; the fixing mechanism two also includes a support rod two movably connected to the support rod one in the transverse direction, the end of the support rod two facing away from the positioning rod having a second slot for connecting transverse rebars.

[0014] By connecting support rod one and support rod two in fixing mechanism two to adjacent transverse reinforcing bars, the positioning rod can be fixed, preventing displacement of the positioning rod when placing untied longitudinal reinforcing bars, thus ensuring positioning accuracy. Through the cooperation of two locking clips, support rod one and support rod two are fixed to the tied transverse reinforcing bars. The structure is simple and easy to operate, and support rod one and support rod two can be flexibly connected transversely, allowing for flexible adjustment of their connection position according to the spacing of adjacent transverse reinforcing bars, making it highly adaptable. This structure simplifies the installation process of the positioning rod, increases its applicability, and enables rapid installation and fixation, making it convenient to use.

[0015] In the aforementioned longitudinal rebar positioning bracket, preferably, the spacing between adjacent limiting slots is 250mm. According to design specifications, the spacing between adjacent longitudinal rebars is generally set to 250mm. By setting the spacing between adjacent limiting slots to 250mm, construction workers can quickly arrange and tie the rebars according to this standard spacing, thus improving construction efficiency. Of course, the spacing between adjacent limiting slots can also be flexibly adjusted according to specific design specifications.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a longitudinal rebar positioning bracket. One end of the positioning rod is equipped with a fixing mechanism one for connecting the already tied longitudinal rebar, and the other end is equipped with a fixing mechanism two for connecting the transverse rebar. Using fixing mechanisms one and two, the positioning rod can be quickly fixed and installed, and positioned using the already tied longitudinal rebar. Once the positioning rod is positioned relative to the tied longitudinal rebar via fixing mechanism one, the positions of the equally spaced limiting slots on the positioning rod are also determined. When the operator places the untied longitudinal rebar into the limiting slots, the position of the longitudinal rebar is determined, thus enabling rapid arrangement of the untied longitudinal rebar. This method eliminates the steps of measuring with a ruler and marking on the circumferential rebar, thereby reducing the difficulty of manual positioning operations and improving construction efficiency. Simultaneously, it effectively prevents the markings from being damaged during construction, leading to incorrect positioning and thus improving construction accuracy. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1 to 3 As shown, the longitudinal rebar positioning bracket of this embodiment includes a positioning rod 1. One end of the positioning rod 1 is provided with a fixing mechanism 2 for connecting the tied longitudinal rebar 01, and the other end is provided with a fixing mechanism 3 for connecting the transverse rebar 02. The positioning rod 1 is also provided with several equidistant limiting slots 4 for fixing the untied longitudinal rebar 01. In use, the positioning rod 1 is fixed by fixing the fixing mechanism 2 and fixing mechanism 3, and the untied longitudinal rebar 01 is placed on the limiting slots 4 to achieve rapid arrangement and precise positioning of the untied longitudinal rebar 01.

[0025] In this embodiment, the positioning rod 1 is bent, and its bending degree is consistent with that of the transverse reinforcing bar 02.

[0026] In this embodiment, the fixing mechanism 2 is configured as a buckle with its opening facing downwards; the limiting slots 4 all open upwards. The fixing mechanism 2 is simply fastened to the already bound longitudinal reinforcing bar 01 to complete the fixing process, which is simple and convenient.

[0027] In this embodiment, the fixing mechanism 2 3 includes a support rod 31 perpendicular to the positioning rod 1. The end of the support rod 31 facing away from the positioning rod 1 has a first latch 311 for connecting the transverse reinforcing bar 02. The fixing mechanism 2 3 also includes a support rod 32 laterally movably connected to the support rod 31. The end of the support rod 32 facing away from the positioning rod 1 has a second latch 321 for connecting the transverse reinforcing bar 02. In use, the fixing mechanism 2 3 is first engaged with the first latch 311 on the transverse reinforcing bar 02 adjacent to the positioning rod 1. The position of the support rod 32 is then adjusted so that its second latch 321 can connect to the other transverse reinforcing bar 02 adjacent to the positioning rod 1. Finally, the support rods 31 and 32 are fixed. This process allows for flexible adjustment of the positions of the support rods 31 and 32 according to the spacing of the transverse reinforcing bars 02, making it highly adaptable.

[0028] In this embodiment, the spacing between adjacent limiting slots 4 is 250mm. By placing untied longitudinal steel bars 01 within the limiting slots 4, the untied longitudinal steel bars 01 can be quickly arranged and accurately positioned. The operation is simple and convenient, which helps to improve the efficiency and accuracy of steel bar tying construction.

[0029] In this embodiment, when using the longitudinal rebar positioning bracket, it is only necessary to use fixing mechanism 1 2 and fixing mechanism 2 3 to fix the positioning rod 1, and place the untied longitudinal rebar 01 in the limiting slot 4 to quickly complete the rapid arrangement and accurate positioning of the untied longitudinal rebar 01, which is convenient to operate.

[0030] like Figure 2 As shown, this reflects the usage state before positioning the longitudinal reinforcing bars. At this time, fixing mechanism 2 is hung on the outermost tied longitudinal reinforcing bar 01, while the second fixing mechanism 3 connects with two adjacent transverse reinforcing bars 02. In this state, the positioning bracket is fixed. At this time, the distance between each limiting slot 4 formed on the positioning rod 1 and fixing mechanism 2 (i.e., the distance between each slot and the tied longitudinal reinforcing bar 01 used for positioning) is fixed. Therefore, the operator only needs to move the untied longitudinal reinforcing bar 01 into each limiting slot 4 to achieve positioning and fixation. After moving the untied longitudinal reinforcing bar 01 into each limiting slot 4, the state is as follows... Figure 3 As shown, the operator can then tie the positioned longitudinal steel bar 01.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
