Description

Technical Field

[0001] This application belongs to the field of bridge and road construction technology, and in particular relates to an installation tool for crossbeam and column connectors. Background Technology

[0002] Bridges and roads are generally equipped with crash barriers, which consist of crossbeams and posts mounted on the crossbeams. For example... Figures 1 to 3 As shown, mounting holes are provided on the crossbeam. The column connectors are fixed in these holes by welding, thus securing the columns to the crossbeam. The column connectors are installed radially onto the crossbeam, requiring high welding precision. Deviations in the installation direction or spacing will prevent the columns from connecting to the crossbeam. Traditional welding methods for column connectors cannot provide accurate positioning and support, resulting in poor directional accuracy and ultimately, a failure to connect the columns to the crossbeam, leading to low construction efficiency.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] This application aims to at least partially solve the technical problems of inaccurate positioning and support during the welding of column connectors, poor installation directional accuracy of column connectors, and low construction efficiency. To this end, this application provides an installation fixture for beam-column connectors.

[0005] This application provides an embodiment of a beam-column connector installation fixture, which includes:

[0006] Base assembly;

[0007] The guide bracket includes a vertical rod assembly disposed on the base assembly and a horizontal bar assembly disposed on the vertical rod assembly, wherein the horizontal bar assembly is provided with a guide corresponding to the mounting hole of the column connector;

[0008] A guide rod is movably mounted on the guide member, and the bottom end of the guide rod is used to mount the column connector.

[0009] In some implementations, the base assembly is matched to the structure of the crossbeam.

[0010] In some embodiments, the base assembly includes two bases arranged opposite each other.

[0011] In some embodiments, the pole assembly includes four poles, with two poles opposite each other on each base;

[0012] The crossbar assembly includes a first crossbar connected between two uprights disposed opposite to the two bases;

[0013] The guide is mounted on the first crossbar.

[0014] In some embodiments, the crossbar assembly further includes a second crossbar that connects the two uprights located on the same base.

[0015] In some embodiments, the crossbar assembly further includes a third crossbar connected between the two uprights disposed opposite to the two bases, and the third crossbar is parallel to the first crossbar.

[0016] The guide members are respectively disposed on the first crossbar and the third crossbar, and are coaxial with the guide members corresponding to the same mounting hole.

[0017] In some embodiments, the guide is a hollow tube, the inner diameter of which matches the outer diameter of the guide rod.

[0018] In some embodiments, the guide rod is threadedly connected to the guide member.

[0019] In some embodiments, the guide rod is provided with a guide limiting part that matches the guide member.

[0020] In some embodiments, the column connector is an internal nut connector, and the bottom end of the guide rod is provided with an external thread that matches the internal nut connector.

[0021] The embodiments of this application have at least the following beneficial effects:

[0022] The aforementioned beam-column connector installation fixture is mounted on the beam via a base assembly.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] This application provides an embodiment of a beam-column connector installation fixture, such as... Figure 4 and Figure 5 As shown, the installation fixture for the beam-column connector includes:

[0035] Base assembly 100;

[0036] The guide bracket 200 includes a vertical rod assembly 210 disposed on the base assembly 100 and a horizontal bar assembly 220 disposed on the vertical rod assembly 210. The horizontal bar assembly 220 is provided with a guide 230 corresponding to the mounting hole 11 of the column connector 20.

[0037] The guide rod 300 is movably mounted on the guide member 230, and the bottom end of the guide rod 300 is used to mount the column connector 20.

[0038] The aforementioned beam-column connector installation fixture is mounted on the beam 10 via a base assembly 100. This allows the guide member 230 on the guide bracket 200 to align with the mounting hole 11 of the column connector 20 on the beam 10. When the guide rod 300 is movably mounted on the guide member 230, the column connector 20 at the bottom of the guide rod 300 aligns with its mounting hole 11. The column connector 20 can then be inserted into its mounting hole 11 via the guide member 230. Under the positioning and limiting action of the guide rod 300, welding is performed, ensuring the correct installation direction of the column connector 20 and improving its accuracy. This allows the column to be accurately installed on the beam 10, preventing rework due to inaccurate welding direction and thus avoiding low construction efficiency.

[0039] like Figures 1 to 3 As shown, the crossbeam 10 of the crash barrier uses a φ159*8 steel pipe, with a single crossbeam 10 being 7490mm long. The crossbeam 10 has three groups of mounting holes 11, each group consisting of four φ36 mounting holes 11. Twelve post connectors 20 are then welded onto the crossbeam 10 to connect with three posts. Optionally, the post connectors 20 can use internal nuts, with the installation direction of the internal nuts being radial to the steel pipe of the crossbeam 10. Since the crossbeam 10 is bolted to the posts through the bolt holes of the internal nuts, the welding precision of the internal nuts is crucial. If the welding precision of the internal nuts does not meet the requirements, resulting in deviations in the installation direction or spacing of the internal nuts, the posts and crossbeam 10 will not be able to connect properly.

[0040] In other embodiments, the location and number of mounting holes 11 groups on the crossbeam 10, and the relative position and number of mounting holes 11 in each mounting hole group 11, can be adaptively adjusted according to the location and number of components such as columns on the crossbeam 10.

[0041] In this disclosure, mounting holes 11 can be drilled on the crossbeam 10 using a computer-programmed plasma cutting device, ensuring that the hole diameter and hole spacing of the mounting holes 11 are within the precision control range. Then, the inner nut of the column connector 20 is positioned in the mounting hole 11 using the crossbeam column connector installation fixture of this disclosure. Finally, the inner nut is welded in the mounting hole 11, thereby ensuring the accuracy of the installation direction of the inner nut on the crossbeam 10.

[0042] In this disclosure, the column connector 20 is positioned by the beam-column connector installation fixture, while ensuring that the column connector 20 has sufficient welding space and that the column connector 20 does not become skewed due to welding stress during the welding process, thus ensuring the installation accuracy of the column connector 20.

[0043] In this embodiment, the guide bracket 200 includes a vertical pole assembly 210 and a horizontal bar assembly 220, wherein the vertical pole assembly 210 is used to support the horizontal bar assembly 220 on the base assembly 100 so that the guide member 230 provided on the horizontal bar assembly 220 can correspond to the mounting hole 11 opened on the crossbeam 10.

[0044] In this embodiment, preferably, the number and position of the guide members 230 in the guide bracket 200 correspond to a group of mounting holes 11 on the crossbeam 10, so that multiple column connectors 20 can be positioned simultaneously through sequential operation, thereby improving the assembly efficiency of the column connectors 20.

[0045] As an alternative implementation, the base assembly 100 is structurally matched with the crossbeam 10. For example... Figure 4 and Figure 5 As shown, in this embodiment, the crossbeam 10 is made of a circular steel pipe, so the base 110 in the base assembly 100 is arc-shaped to match the circular steel pipe.

[0046] In this embodiment, in order to fix the base assembly 100 to the crossbeam 10, for example, the base assembly 100 can be made magnetic, so that the base assembly 100 is fixed to the crossbeam 10 by magnetic attraction; or, the base assembly 100 can be provided with a snap-fit ​​structure, so that the base assembly 100 can be fixed to the crossbeam 10 by a snap-fit ​​structure; or, the base assembly 100 can be provided with a snap-fit ​​member that matches the base 110, so that the base 110 is snapped and fixed to the crossbeam 10 by connecting the snap-fit ​​member to the base 110.

[0047] In other embodiments, the crossbeam 10 may also be made of a structure other than a circular steel tube. For example, the crossbeam 10 may be made of a rectangular steel tube, and the base 110 in the base assembly 100 may be a plate-like structure to match the rectangular steel tube.

[0048] As an alternative implementation, the base assembly 100 includes two relatively parallel bases 110. For example... Figure 4 and Figure 5 As shown, in the beam-column connector installation fixture of this embodiment, the base assembly 100 has two bases 110. The two bases 110 are arranged in the beam 10 at a certain distance and relatively parallel. The space between the two bases 110 is used to set the guide bracket 200 and the guide rod 300 so that the column connector 20 can be positioned and welded within the space. At the same time, the two bases 110 are arranged at intervals and parallel on the beam 10, which can also improve the stability of the base assembly 100 on the beam 10. This facilitates the positioning of the column connector 20 by the guide rod 300, increases the stability of the positioning, increases the resistance to welding stress, and avoids the column connector 20 from being misaligned due to welding stress.

[0049] As an optional implementation, the upright assembly 210 includes four uprights 211, with two uprights 211 opposite each other on each base 110; the crossbar assembly 220 includes a first crossbar 221, which connects the two uprights 211 oppositely disposed on the two bases 110; a guide member 230 is disposed on the first crossbar 221. Figure 4 and Figure 5 As shown, in this embodiment, in order to enable the upright assembly 210 to stably support the crossbar assembly 220, two uprights 211 are provided opposite to each base 110; at the same time, a first crossbar 221 is provided between the two uprights 211 that are opposite to each other on the two bases 110, so that the first crossbar 221 can be arranged parallel to the crossbeam 10 above the crossbeam 10, thereby enabling the guide 230 provided on the first crossbar 221 to correspond to the mounting hole 11 on the crossbeam 10. In this embodiment, since each group of mounting holes 11 has four mounting holes 11 and the group of mounting holes 11 is rectangularly distributed, the crossbar assembly 220 includes two first crossbars 221. The two first crossbars 221 are suspended above the crossbeam 10 by two uprights 211 that are relatively disposed on the two bases 110, and the two first crossbars 221 are relatively parallel, so that each first crossbar 221 is provided with two guide members 230. A total of four guide members 230 can be provided on the two first crossbars 221 to correspond to the number of mounting holes 11 in the group of mounting holes 11.

[0050] In other embodiments, the upright assembly 210 may also be configured in other ways. For example, only one upright 211 may be provided on each base 110, and the first crossbar 221 may be suspended above the crossbeam 10 by a total of two uprights 211.

[0051] As an optional implementation, the crossbar assembly 220 further includes a second crossbar 222, which connects the two uprights 211 located on the same base 110. Figure 4 and Figure 5 As shown, in order to ensure the stability of the guide bracket 200, a second crossbar 222 is provided between the two uprights 211 on the same base 110. The stability of the guide bracket 200 is increased by the second crossbar 222, especially to ensure the stability of the relative distance between the two first crossbars 221, thereby improving the accuracy of the corresponding angle between the guide member 230 and the mounting hole 11, and thus ensuring that the angle of the guide rod 300 corresponds to the mounting hole 11.

[0052] As an optional implementation, the crossbar assembly 220 further includes a third crossbar 223, which connects to two uprights 211 disposed opposite to each other on the two bases 110, and the third crossbar 223 is parallel to the first crossbar 221; guide members 230 are respectively disposed on the first crossbar 221 and the third crossbar 223, and all guide members 230 corresponding to the same mounting hole 11 are coaxial. Figure 4 and Figure 5 As shown, in this embodiment, in order to enhance the guiding effect of the guide member 230, a third crossbar 223 is provided between the two uprights 211 on the two bases 110, so that the third crossbar 223 is relatively parallel to the first crossbar 221 and relatively parallel to the crossbeam 10. The first crossbar 221 and the third crossbar 223 are respectively provided with guide members 230 corresponding to the same mounting hole 11, so as to improve the accuracy of the corresponding angle between the guide member 230 and the corresponding mounting hole 11, improve the angular guiding effect on the guide rod 300, and thus improve the angular guiding effect on the column connector 20. In this embodiment, each group of mounting holes 11 has four mounting holes 11. Therefore, two guide members 230 are provided on the two first crossbars 221 and two guide members 230 are provided on the two third crossbars 223, for a total of eight guide members 230. Each pair of guide members 230 is used to guide one guide rod 300 and enhances the angle limiting effect on the guide rod 300 to overcome the welding stress on the column connector 20 during welding.

[0053] As an optional implementation, the guide member 230 is a hollow tube, and the inner diameter of the hollow tube matches the outer diameter of the guide rod 300. For example... Figure 4 and Figure 5As shown, in this embodiment, the guide rod 300 is a round rod, so the hollow tube that serves as the guide member 230 is a hollow round tube. Since the inner diameter of the hollow round tube matches the outer diameter of the round rod that serves as the guide rod 300, the hollow round tube can precisely limit the angle of the round rod, so that the bottom end of the round rod can be inserted into the mounting hole 11.

[0054] In other embodiments, the guide rod 300 may also be a rectangular rod. Accordingly, in order for the guide member 230 to limit the angle of the rectangular rod, the guide member 230 is a hollow rectangular tube.

[0055] As an optional implementation, the guide rod 300 is threadedly connected to the guide member 230. For example... Figure 4 and Figure 5 As shown, in this embodiment, by threading the guide rod 300 to the guide member 230, the guide rod 300 can be moved relative to the guide member 230 to adjust the distance between the bottom end of the guide rod 300 and the mounting hole 11 so as to adjust the position of the column connector 20; the guide rod 300 can also be fixed relative to the guide member 230 by the thread so as to position the column connector 20 during the welding process.

[0056] As an optional implementation, the guide rod 300 is provided with a guide limiting part that matches the guide member 230. In this embodiment, for example, the guide limiting part is provided on the side wall of the guide rod 300, and the distance between the guide limiting part and the bottom end of the guide rod 300 is adapted to the distance between the guide member 230 and the crossbeam 10, so that the column connector 20 provided at the bottom end of the guide rod 300 is located at the designed position of the mounting hole 11. Alternatively, the guide limiting part is provided at the top end of the guide rod 300, which can limit the position of the guide rod 300 relative to the guide member 230 to prevent the guide rod 300 from falling out of the guide member 230. The setting method and setting position of the guide limiting part can be adaptively adjusted as needed.

[0057] As an optional implementation, the column connector 20 is an internal nut connector, and the bottom end of the guide rod 300 is provided with an external thread that matches the internal nut connector. In this embodiment, the internal nut of the column connector 20 is connected to the external thread at the bottom end of the guide rod 300, thereby allowing the column connector 20 to be detachably mounted at the bottom end of the guide rod 300. This allows the column connector 20 to be inserted into the designed depth of the mounting hole 11 via the guide rod 300, and then welded to the crossbeam 10.

[0058] The steps for welding the column connector 20 to the crossbeam 10 using the beam-column connector installation fixture disclosed herein are as follows:

[0059] The beam and column connector installation fixture is fixed on the beam 10, and the guide rod 300 can be radially inserted into the mounting hole 11 through the guide member 230 of the guide bracket 200.

[0060] The inner nut, which serves as the column connector 20, is connected to the bottom end of the guide rod 300. The guide rod 300 is used to adjust the depth of the inner nut in the radial direction into the crossbeam 10 so that the inner nut protrudes no more than 2mm from the outer surface of the crossbeam 10.

[0061] The inner nut is pre-fixed in the mounting hole 11 by spot welding, with no less than three spot welding points. Then the inner nut is welded and fixed in the mounting hole 11.

[0062] Remove the guide rod 300 and the inner nut, and remove the beam column connector installation tooling from the beam 10;

[0063] Grind the portion of the inner nut weld 30 that protrudes from the outer surface of the crossbeam 10 until it is flush with the outer surface of the crossbeam 10.
