Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a straight tie rod that is easy to install. Background Technology

[0002] In the field of building structures, tie rods, as an important connecting component, are widely used in various steel structure buildings, especially in the connection and fixation between two purlins, playing a key role. They effectively transfer the tensile force between purlins, enhancing the overall stability of the structure and its wind and earthquake resistance, ensuring the safety and reliability of the building in various complex environments.

[0003] Currently, the commonly available tie rods have many drawbacks in their installation methods, causing great inconvenience to actual construction. Specifically, when installing this traditional tie rod between two purlins, both ends of the tie rod need to be passed through pre-drilled mounting holes on the two purlins. Due to the long length of the tie rod and the limited space between the purlins, construction workers need to expend considerable effort and time to accurately align the mounting holes and complete the drilling operation. This difficulty is particularly pronounced when dealing with multi-story buildings or large steel structure projects.

[0004] After perforation, securing the tie rod is equally tedious. Conventionally, washers need to be inserted into each end of the tie rod and nuts tightened to ensure a secure connection between the tie rod and the purlin (e.g., Figure 6 The installation process typically requires multiple workers to collaborate simultaneously. When drilling holes and tightening nuts, one person needs to hold the straight rod in place, while another operates the tools to tighten it. This not only increases labor costs but also demands a high degree of coordination between the workers. Any miscommunication between workers could lead to installation errors or safety accidents. Utility Model Content

[0005] The purpose of this invention is to provide a convenient straight pull strip to solve the above-mentioned problems in the prior art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A conveniently installed straight pull rod includes a first connecting rod, a second connecting rod, a screw, and a nut. The outer ends of the first and second connecting rods are respectively engaged with the mounting holes of two purlins through a first limiting cap and a second limiting cap. The inner ends of the first and second connecting rods are respectively inserted into each other through a concave block and a convex block. A first limiting hole is vertically opened through the concave block, and a second limiting hole is opened on the convex block corresponding to the first limiting hole. The bottom of the screw passes through the upper first limiting hole, the second limiting hole, and the lower first limiting hole in sequence before being threaded into the nut.

[0007] The beneficial effects of this utility model are: by setting a first connecting rod, a second connecting rod, a concave block, a convex block, and screws and nuts, the straight tie rod can be installed separately. The first connecting rod and the second connecting rod pass through the mounting hole of the purlin on one side, which is simple. When installing screws, multiple construction workers do not need to work at the same time. One person can complete the work, saving labor costs.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the end faces of both the concave and convex blocks are square.

[0010] The further beneficial effects of the above are: when the concave block and the convex block are inserted, the square end face can restrict the relative rotation of the concave block and the convex block, which is conducive to the alignment of the first limiting hole and the second limiting hole. At the same time, it can also avoid the bending and misalignment of the first connecting rod and the second connecting rod, and improve the overall strength of the first connecting rod and the second connecting rod.

[0011] Furthermore, the concave block has two or more first limiting holes spaced laterally, and the convex block has two or more second limiting holes correspondingly spaced laterally.

[0012] The further beneficial effect of adopting the above is that the simultaneous connection of multiple first limiting holes, second limiting holes, and multiple sets of screws and nuts can improve the connection strength between the concave block and the convex block, thereby further improving the connection strength of the first connecting rod and the second connecting rod.

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] Example 1 like Figures 1 to 5 As shown, a convenient straight pull bar includes a first connecting rod 1, a second connecting rod 2, a screw 3, and a nut 4. The outer ends of the first connecting rod 1 and the second connecting rod 2 are respectively engaged with the mounting holes 51 of the two purlins 5 through the first limiting cap 11 and the second limiting cap 21. The inner ends of the first connecting rod 1 and the second connecting rod 2 are respectively inserted into each other through the concave block 12 and the convex block 22. The concave block 12 has a first limiting hole 13 vertically penetrating through it, and the convex block 22 has a second limiting hole 23 corresponding to the first limiting hole 13. The bottom of the screw 3 passes through the upper first limiting hole 13, the second limiting hole 23, and the lower first limiting hole 13 in sequence and is then threadedly connected to the nut 4.

[0017] The first connecting rod 1 and the second connecting rod 2 are respectively inserted into the mounting holes 51 of the purlin 5, and the inner ends of the first connecting rod 1 and the second connecting rod 2 are respectively inserted into each other through the concave block 12 and the convex block 22. The first limiting cap 11 and the second limiting cap 21 are respectively locked into the mounting holes 51 to complete the pre-installation of the first connecting rod 1 and the second connecting rod 2. Then, the screw 3 is inserted into the first limiting hole 13 and the second limiting hole 23. After the screw 3 passes through the lower first limiting hole 13, the nut 4 is tightened to fix the first connecting rod 1 and the second connecting rod 2. By setting the first connecting rod 1, the second connecting rod 2, the concave block 12, the convex block 22, the screw 3, and the nut 4, the separate installation of the straight tie rod is realized. The first connecting rod 1 and the second connecting rod 2 simply pass through the mounting holes 51 of the purlin 5 on one side. When installing the screw 3, multiple construction workers do not need to work at the same time. One person can complete the work, saving labor costs.

[0018] Example 2 like Figures 1 to 5 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: Both the concave block 12 and the convex block 22 have square end faces. When the concave block 12 and the convex block 22 are inserted, the square end faces can restrict the relative rotation of the concave block 12 and the convex block 22, which is beneficial to the alignment of the first limiting hole 13 and the second limiting hole 23. At the same time, it can also prevent the bending and misalignment of the first connecting rod 1 and the second connecting rod 2, thereby improving the overall strength of the first connecting rod 1 and the second connecting rod 2.

[0019] Example 3 like Figures 1 to 5 As shown, this embodiment is a further improvement on embodiment 2, as detailed below: Two or more first limiting holes 13 are laterally spaced on the concave block 12, and two or more second limiting holes 23 are laterally correspondingly provided on the convex block 22. The simultaneous connection of multiple first limiting holes 13, second limiting holes 23, and multiple sets of screws 3 and nuts 4 can improve the connection strength between the concave block 12 and the convex block 22, thereby further improving the connection strength between the first connecting rod 1 and the second connecting rod 2.

[0020] Example 4 like Figures 1 to 5 As shown, this embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below: The recessed block 12 has a recessed platform 121 that retracts horizontally towards the middle of the first connecting rod 1 at both the upper and lower parts. Compared with the arc-shaped surface, the recessed platform 121 provides a larger horizontal operating space, making it easier for construction workers to install screws 3 and nuts 4.

[0021] The first limiting hole 13 at the top of the recess 12 is a countersunk hole. The countersunk hole provides better stability, reduces the risk of screw 3 loosening, and ensures the stability and reliability of the connection.

[0022] Screw 3 is a hex socket head cap screw. Hex socket head cap screws are suitable for use in confined spaces and can withstand greater loads than other types of screws, making them suitable for high-strength applications such as those described in this application.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
