Description

Technical Field

[0001] This utility model relates to a welding positioning fixture, specifically a welding positioning fixture for I-beams and connecting plates. It is mainly used for auxiliary positioning of I-beams and connecting plates during the welding process and belongs to the field of I-beam processing technology. Background Technology

[0002] Generally, during the construction of tunnel steel arch frames, because I-beams cannot be bent into shape in one go, two I-beams need to be connected by welding connecting plates and then bolted together. Therefore, the welding quality of the connecting plates directly affects the torsional deformation and tilt of the steel arch frame, among other quality control points. Traditional welding processes result in unsightly finishes and uncontrollable quality, seriously affecting the processing and installation quality of the steel arch frame, leading to…

[0003] This method results in substandard load-bearing performance and potential safety hazards. The processing is slow and the connection position error is large. When multiple steel arch frames are connected, the smoothness of the arch frame cannot be guaranteed, which affects the overall load-bearing effect of the tunnel's initial support.

[0004] Furthermore, in the existing arch frame processing, the accuracy of the positioning of the connecting steel plate directly affects whether the arch frame can be assembled smoothly. If the positioning is inaccurate, the bolt holes will often not be aligned, resulting in the bolts not being able to be installed in full. The arch frame line will not be straight due to the position of the connection between the steel arch frame and the connecting plate. In short, it is often very inconvenient.

[0005] According to the search, Chinese utility model patent with patent announcement number CN216421516U discloses a welding auxiliary device for a tunnel steel arch frame connecting plate, including a welding auxiliary device body for welding the auxiliary connecting plate (3) to the end welding point of the I-beam (4), the welding auxiliary device body including a clamp (1) and a positioning detection component (2);

[0006] The clamp (1) includes a clamping plate (5) and a stabilizing plate (8). The clamping plate (5) has a groove (6) on one side, which is clamped onto the I-beam (4). The clamping plate (5) has several positioning holes (7). The stabilizing plate (8) is fixed to one end of the clamping plate (5) and is used to place the connecting plate (3). The positioning detection component (2) includes a connecting block (13). One end of the connecting block (13) is provided with a first positioning plate (11), and the other end is provided with a second positioning plate (16). The other side of the first positioning plate (11) is provided with several positioning detection posts (15).

[0007] The card plate (5) is secured to the I-beam (4) via the card slot (6), the connecting plate (3) is placed on the stabilizing plate (8), and the surface of the connecting plate (3) is in contact with the I-beam (4). The connecting block (13) is placed in the steel groove of the I-beam (4), and the first positioning plate (11) and the second positioning plate (16) of the connecting block (13) slide along the steel groove. When several positioning detection columns (15) in the first positioning plate (11) pass through several positioning holes (7) of the card plate (5) respectively, they are inserted into the bolt holes of the connecting plate (3), thereby realizing the positioning of the connecting plate (3) at the end of the I-beam (4). Although the above patent can solve the problem of difficulty in controlling the welding quality of the connecting plate on the I-beam, the following technical defects and shortcomings still exist in the use process:

[0008] On the one hand, the patent has a complex structure and is cumbersome to use. The connection between the clamping plate and the stabilizing plate (such as the welding joint) is subjected to external force and vibration for a long time, which can easily lead to deformation and cracking, resulting in a weakening of the supporting effect of the stabilizing plate on the connecting plate and a shift in the positioning reference.

[0009] On the other hand, the connection between the connecting block, positioning plate and positioning detection column of the positioning detection component is prone to loosening after repeated sliding and insertion, causing the spatial position of the positioning detection column to shift, which to some extent damages the positioning accuracy.

[0010] Therefore, the key to solving the above-mentioned technical problems lies in developing a simple and practical welding and positioning fixture for I-beams and connecting plates. Summary of the Invention

[0011] To address the numerous defects and shortcomings in the aforementioned background technology, this utility model has made improvements and innovations. The aim is to provide a simple, easy-to-construct, and conveniently operated solution that improves the welding quality of the I-beam connecting plate on the I-beam. By using a positioning auxiliary handheld device, the utility model is placed in the I-beam's steel channel, facilitating operation and positioning, improving the positioning accuracy of the I-beam connecting plate on the I-beam, and providing convenient hand-held clamping during use. A single person can complete the workpiece placement and clamp installation and fixation without the need for prolonged manual support or repeated measurements. After being fixed by the clamp, the worker can stay away from the weld area and focus solely on the welding operation, reducing the risk of direct contact.

[0012] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides a welding positioning fixture for I-beams and connecting plates, achieved through the following design structure and technical solution:

[0013] A positioning fixture for welding an I-beam to a connecting plate includes:

[0014] Install the base plate, which is placed in the I-beam channel at the end of the steel arch frame.

[0015] Positioning plate, which is vertically connected to one end of the mounting base plate;

[0016] Positioning components are symmetrically arranged on the positioning plate and are used to pass through the I-beam connecting plate and position it.

[0017] The handheld component has one end connected to the mounting base plate and the other end connected to the positioning plate.

[0018] The reinforcing plate positioning hole is a through hole opened in the middle of the connection between the mounting base plate and the positioning plate, used to position the I-beam reinforcing plate.

[0019] Preferably, the mounting base plate is an elongated plate-shaped component;

[0020] The positioning plate is an inverted U-shaped plate-like component. It has symmetrical inwardly provided slots on both sides of the inverted U-shaped plate-like component. The slots are used to engage with the web plates on both sides of the steel arch frame during use.

[0021] Preferably, both the mounting base plate and the positioning plate are made of stainless steel.

[0022] Preferably, the mounting base plate and the positioning plate are welded together or directly processed into an integral structure.

[0023] Preferably, the positioning plate has two positioning holes through the middle; the positioning element is a positioning bolt, which passes through each positioning hole and is welded to the positioning plate.

[0024] Preferably, the handheld component is a bent rod-shaped structure made by cutting and grinding steel bars.

[0025] Preferably, the outer surface of the handheld component is covered with a matching anti-slip sleeve, which is disposed on the handheld part of the handheld component.

[0026] Preferably, the anti-slip sleeve is a rubber layer with several rubber anti-slip protrusions on it.

[0027] Preferably, the positioning hole of the reinforcing plate is an L-shaped hole.

[0028] Preferably, the mounting base plate, positioning plate, positioning components, and handheld components are installed.

[0029] The outer surface is provided with an injection molding layer, a rust-proof layer, a waterproof layer, and a warning layer in sequence from the inside to the outside. The warning layer is coated with fluorescent powder.

[0030] The working principle is as follows: Before using the welding positioning fixture for the I-beam and connecting plate of the above-mentioned design structure, the already manufactured welding positioning fixture needs to be transported to the designated construction site by manual labor or by handling equipment.

[0031] In use, the operator simply holds the holding piece (4) and uses the slots (21) on both sides of the positioning plate (2) to attach the utility model to the web plates on both sides of the steel arch frame (6) and adjust its position. The mounting base plate (1) is then placed inside the I-beam groove (61). Subsequently, the operator inserts the I-beam connecting plate (62) to be welded onto the positioning piece (3) and welds it. Simultaneously, after the I-beam connecting plate (62) is welded, the operator again uses the positioning hole (5) on the reinforcing plate to... A marker is used to make a positioning mark on the I-beam connecting plate (62) that corresponds to the positioning hole (5) of the reinforcing plate. This positioning mark is the welding position of the I-beam reinforcing plate (63). Then, the clamp can be removed by lifting it upwards with the hand-held part (4). Finally, the operator welds the I-beam reinforcing plate (63) to the I-beam steel channel (61) and the I-beam connecting plate (62) according to the positioning mark. After welding, a steel arch frame (6) is formed. Repeat the above operation steps to complete the welding work of other steel arch frames. The entire welding process does not require hand-held operation. The use of this clamp greatly improves the work efficiency and avoids the quality hazards of the segmented assembly of the arch frame caused by inaccurate positioning of the I-beam and the I-beam connecting plate, such as the arch frame twisting, eccentric force, and failure to meet the verticality requirements after installation in the hole.

[0032] Finally, as time goes by, once all the welding work is completed, the operators only need to clean and repair the various parts of this utility model, and then transport them manually or with appropriate handling equipment to the designated tool storage warehouse for storage, so that they can be reused next time.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] 1. This utility model has a simple structure, easy construction, and convenient operation. It improves the welding quality of the I-beam connecting plate on the I-beam. By using the positioning auxiliary handheld part, the utility model is placed in the steel channel of the I-beam, which facilitates operation and positioning, improves the positioning accuracy of the I-beam connecting plate on the I-beam, and makes it convenient to carry the clamp during use. A single person can complete the workpiece placement and clamp installation and fixation without the need for long-term manual support or repeated measurement. After being fixed by the clamp, the worker can stay away from the weld area and focus only on the welding operation, reducing the risk of direct contact.

[0035] 2. This utility model of the connecting plate welding and installation tool solves the manufacturing problem of poor welding quality and docking accuracy without measuring tools. In actual construction, all materials for processing the connecting plate welding and installation tool can be obtained locally on the construction site, which has strong operability.

[0036] 3. This fixture not only enables the fabrication of H-beams and H-beam connecting plates, but also improves the welding quality of H-beams and the positional accuracy of H-beam connecting plates, thus enabling rapid construction while increasing the efficiency and accuracy of the welding fabrication of H-beams and connecting plates.

[0037] 4. This utility model of connecting plate welding and installation tool overcomes the need for two people to work together during processing, and fully considers the requirements of saving costs and speeding up the project progress. It avoids delays in construction due to misalignment of the connecting plate holes when assembling the arch frame, or the inability to ensure safety and quality when only a few holes are aligned. It ensures the quality of the steel arch frame after processing and welding.

[0038] 5. Because the hand-held part of the hand-held component is covered with an anti-slip protective sleeve, this utility model can protect the operator's hands from wear and tear during long-term work, thus ensuring construction safety.

[0039] 6. Because this utility model is equipped with a reinforcing plate positioning hole, it can be used to position the H-beam reinforcing plate during the welding process, ensuring that the welding position of the H-beam reinforcing plate is accurate and reliable, and improving the work efficiency and accuracy of welding and manufacturing of H-beams and H-beam reinforcing plates;

[0040] 7. The exterior of this utility model is coated with anti-rust paint and a waterproof layer, which can prevent rusting and extend the service life of the entire device. It is environmentally friendly and saves resources. At the same time, the exterior of the device is coated with a self-luminous fluorescent material, which can clearly mark the location of the laying device at night or in dark indoor and underground construction environments. It can effectively play a safety reminder role, improve visibility, make it easy for people to identify, and increase safety in construction and life.

[0041] 8. This clamp, through precise hole positioning, enables accurate positioning of the I-beam connecting plate and the I-beam reinforcing plate during welding of the arch frame and connecting plate. It is simple to use; simply place the clamp on the web of the I-beam and adjust its position, place the alignment bolts on the connecting plate and weld. The entire welding process does not require manual handling. After the I-beam and connecting plate are welded, the clamp can be removed. This greatly improves work efficiency and avoids potential quality problems in the segmented assembly of the arch frame caused by inaccurate positioning of the I-beam and connecting plate, such as arch frame twisting, eccentric stress, and failure to meet verticality requirements after installation in the hole.

The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] like Figures 1 to 9 The illustrated positioning fixture for welding an I-beam to a connecting plate includes:

[0060] Install base plate 1, which is placed in the I-beam steel channel 61 at the end of the steel arch frame 6.

[0061] Positioning plate 2 is vertically connected to one end of mounting base plate 1;

[0063] Handheld component 4, one end of which is connected to the mounting base plate 1, and the other end of which is connected to the positioning plate 2;

[0064] The reinforcing plate positioning hole 5 is opened through the middle of the connection between the mounting base plate 1 and the positioning plate 2, and is used to position the I-beam reinforcing plate 63.

[0065] Furthermore, such as Figures 5 to 8 As shown, the mounting base plate 1 is an overall elongated plate-shaped component;

[0066] The positioning plate 2 is an inverted U-shaped plate-shaped component. On both sides of the inverted U-shaped plate-shaped component, there are symmetrical inwardly provided slots 21. The slots 21 are used to engage with the web plates on both sides of the steel arch frame 6 when in use.

[0067] Specifically, both the mounting base plate 1 and the positioning plate 2 are made of stainless steel.

[0068] More specifically, the mounting base plate 1 and the positioning plate 2 are either welded together or directly processed into an integral structure.

[0069] Furthermore, two positioning holes are formed through the middle of the positioning plate 2; the positioning element 3 is a positioning bolt, which passes through each positioning hole and is welded to the positioning plate 2.

[0070] Furthermore, the handheld component 4 is a bent rod-shaped structure made by cutting and grinding steel bars.

[0071] Specifically, such as Figure 9 As shown, the outer surface of the handheld component 4 is covered with a matching anti-slip sleeve 41, which is disposed on the handheld part of the handheld component 4.

[0072] More specifically, such as Figure 9 As shown, the anti-slip sleeve 41 is a rubber layer, on which several rubber anti-slip protrusions are provided.

[0073] In this invention, the rubber anti-slip protrusions are granular or annular protrusions. Therefore, since the anti-slip sleeve is provided on the hand grip part of the hand grip 4, it can protect the operator's hands from wear and tear during long-term work, thus ensuring construction safety.

[0074] Furthermore, the positioning hole 5 of the reinforcing plate is an L-shaped hole.

[0075] Furthermore, the base plate 1, positioning plate 2, positioning component 3, and handheld component 4 are installed.

[0076] The outer surface is provided with an injection molding layer, a rust-proof layer, a waterproof layer, and a warning layer in sequence from the inside to the outside. The warning layer is coated with fluorescent powder.

[0077] In this invention, a polymer wear-resistant material is injection molded onto the injection molding layer; the anti-rust layer includes an epoxy zinc-rich primer and a chlorinated rubber topcoat, as well as an epoxy micaceous iron oxide intermediate paint located between the epoxy zinc-rich primer and the chlorinated rubber topcoat; the waterproof layer is a polyurethane waterproof coating; and the warning layer is a reflective warning tape, reflective film, or reflective paint of a single color or a mixture of multiple colors.

[0078] Meanwhile, in this utility model, all connections referred to are fixed connections, movable connections, or detachable connections. Among them, fixed connections are welded connections or directly processed into an integral structure; movable connections, detachable connections, or split structures are hinged connections, internal and external threaded connections, bayonet connections, plug-in sleeves, bolt assembly connections, or screw connections.

[0079] In summary, a more specific embodiment of this utility model is as follows:

[0080] Before using the welding positioning fixture for the I-beam and connecting plate of the above-mentioned design structure, the already manufactured welding positioning fixture needs to be transported to the designated construction site manually or by handling equipment.

[0081] In use, the operator simply holds the holding piece 4 and uses the slots 21 on both sides of the positioning plate 2 to attach the utility model to the two side webs of the steel arch frame 6 and adjust its position. The mounting base plate 1 is then placed inside the I-beam steel channel 61. Subsequently, the operator inserts the I-beam connecting plate 62 to be welded onto the positioning piece 3 and welds it. At the same time, after the I-beam connecting plate 62 is welded, the operator again uses a marker to make a corresponding positioning mark on the I-beam connecting plate 62 through the reinforcing plate positioning hole 5. This positioning mark is the welding position of the I-beam reinforcing plate 63. Then, by lifting upwards with the holding piece 4, the clamp can be removed. Finally, the operator welds the I-beam reinforcing plate 63 between the I-beam steel channel 61 and the I-beam connecting plate 62 according to the positioning mark. After welding, the steel arch frame 6 is formed. The above operation steps are repeated to complete the welding work of other steel arch frames. The entire welding process does not require manual handling. The use of this clamp greatly improves work efficiency and avoids potential quality problems in the segmented assembly of the arch frame, such as arch frame twisting, eccentric stress, and failure to meet verticality requirements after installation in the hole due to inaccurate positioning of the I-beams and I-beam connecting plates.

[0082] Finally, as time goes by, once all the welding work is completed, the operators only need to clean and repair the various parts of this utility model, and then transport them manually or with appropriate handling equipment to the designated tool storage warehouse for storage, so that they can be reused next time.

[0083] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
