Description

Technical Field

[0001] This invention relates to the field of shipbuilding engineering technology, and in particular to a method for assembling T-beams. Background Technology

[0002] T-beam structures are common in shipbuilding and steel structure engineering. Ship structures contain a large number of T-beams, and assembling each ship's T-beams is a labor-intensive task, consuming significant manpower and resources. Currently, T-beam assembly is generally completed in the assembly workshop, primarily using two methods: One method involves laying the T-beam panel flat on the ground, then using a crane to vertically place the web plate onto the panel. At least two people are needed to support the web plate and align it with the mounting line on the front panel, while another person performs spot welding. The disadvantage of this method is the need for at least two people working together and the use of a crane. The other method involves fabricating auxiliary fixtures. The panel is placed in the bottom groove of the auxiliary fixture, then the web plate is placed into the vertical groove of the auxiliary fixture using a crane, and finally, the web plate is aligned with the mounting line on the front panel and spot welded. The disadvantage of this method is the need for a crane and the fabrication of numerous complex auxiliary fixture components.

[0003] Therefore, a T-beam assembly method is urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a T-beam assembly method to solve the problem that the existing T-beam assembly requires a lot of manpower and is inefficient.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A method for assembling a T-beam, comprising:

[0007] Step S1: Lay the panel and web flat on the ground, and then use a marking tool to draw the installation line of the web installation position on the panel;

[0008] Step S2: Use a pry bar to lift one side of the web plate so that the web plate is at an angle to the ground. Then insert a first pad between the web plate and the ground and remove the pry bar.

[0009] Step S3: Use the iron pry bar to pry up one side of the panel so that the panel is set at an angle to the ground, then insert the first pad between the panel and the ground, and remove the iron pry bar;

[0010] Step S4: Check whether the end of the web plate that is off the ground is aligned with the mounting line and perpendicular to the panel. If so, weld one side of the end of the web plate that is off the ground to the panel. If not, place a second shim on the end of the panel that is in contact with the ground, adjust the end of the web plate that is off the ground to align with the mounting line using the second shim, then spot weld one side of the end of the web plate that is off the ground to the panel, fine-tune the web plate to make it perpendicular to the panel, and then fully weld one side of the end of the web plate that is off the ground to the panel.

[0011] Step S5: Use a pry bar to flip the panel and the web over, and fully weld the other side of the end of the web that is off the ground to the panel.

[0012] Preferably, in step S2, the prying height of one side of the web is controlled to be half the width of the panel.

[0013] Preferably, in step S2, the angle between the web and the ground is controlled to be between 5° and 10°.

[0014] Preferably, if the length of the web exceeds 3m, a first pad is provided at the middle position of the web along the length direction of the web to support the web.

[0015] Preferably, in step S4, the perpendicularity of the web and the panel is checked using a square. If the web and the panel do not meet the perpendicularity requirements, the web is finely adjusted using a pry bar to make the web perpendicular to the panel.

[0016] Preferably, one end of the iron pry bar is provided with a pry blade, and the other end is provided with a slot, so that both the panel and the web can be inserted into the slot.

[0017] Preferably, the second pad is wedge-shaped.

[0018] The beneficial effects of this invention are:

[0019] The T-beam assembly method provided in this embodiment involves using a pry bar to lift one side of the web plate, with a first pad used to maintain the web plate's posture. Then, the panel is also pryed up on one side using the pry bar, aligning the end of the web plate off the ground with the installation line on the panel and perpendicular to it. A second pad is then used to maintain the panel's posture. This allows the web plate to be welded to the panel along the installation line without manual support. After one side is welded, the panel and web plate are flipped over using the pry bar, and the other side is welded along the installation line, thus completing the assembly of the web plate and panel. This method eliminates the need for multiple people to work together; a single person can assemble the web plate and panel, improving assembly efficiency. Furthermore, this method eliminates the need for cranes for lifting and the fabrication of auxiliary tooling, effectively saving resources. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0037] like Figures 1 to 7 As shown, this embodiment provides a T-beam assembly method, including:

[0038] Step S1: Lay the panel 1 and the web 2 flat on the ground, and then use a marking tool to draw the installation line 11 on the panel 1 to indicate the installation position of the web 2.

[0039] Step S2: Use the iron pry bar 3 to pry up one side of the web plate 2 so that the web plate 2 is set at an angle to the ground. Then insert the first pad 4 between the web plate 2 and the ground, and remove the iron pry bar 3.

[0040] Step S3: Use the iron pry bar 3 to pry up one side of the panel 1 so that the panel 1 is set at an angle to the ground. Then insert the first pad 4 between the panel 1 and the ground and remove the iron pry bar 3.

[0041] Step S4: Check whether the end of the web plate 2 that is off the ground is aligned with the mounting line 11 and perpendicular to the panel 1. If so, weld one side of the end of the web plate 2 that is off the ground to the panel 1. If not, place a second pad 5 on the end of the panel 1 that is in contact with the ground, adjust the end of the web plate 2 that is off the ground to align with the mounting line 11 using the second pad 5, then spot weld one side of the end of the web plate 2 that is off the ground to the panel 1, fine-tune the web plate 2 so that the web plate 2 is perpendicular to the panel 1, and then fully weld one side of the end of the web plate 2 that is off the ground to the panel 1.

[0042] Step S5: Use the iron pry bar 3 to flip the panel 1 and the web 2 over, and fully weld the other side of the end of the web 2 that is off the ground to the panel 1.

[0043] The T-beam assembly method provided in this embodiment involves using a pry bar 3 to lift one side of the web plate 2, and using a first pad block 4 to maintain the posture of the web plate 2. Then, using the pry bar 3, one side of the panel 1 is lifted, aligning the end of the web plate 2 off the ground with the installation line 11 on the panel 1 and perpendicular to the panel 1. A second pad block 5 is then used to maintain the posture of the panel 1. Thus, without manual support, the web plate 2 can be welded to the panel 1 along the installation line 11. After welding one side, the panel 1 and web plate 2 are flipped over using the pry bar 3, allowing welding to be performed on the other side along the installation line 11, thereby completing the assembly of the web plate 2 and panel 1. This method eliminates the need for multiple people to work together; a single person can complete the assembly of the web plate 2 and panel 1, improving assembly efficiency. Furthermore, this method eliminates the need for a crane for lifting and the fabrication of auxiliary tooling, effectively saving resources.

[0044] Optionally, in step S2, the prying height of one side of the web plate 2 is controlled to be half the width of the panel 1. It can be understood that, since the mounting line 11 in this embodiment is located at the middle position of the panel 1 along the width direction, by controlling the prying height of one side of the web plate 2 to be half the width of the panel 1, it is convenient to initially align the web plate 2 with the mounting line 11.

[0045] Optionally, in step S2, the angle between the web plate 2 and the ground is controlled to be between 5° and 10°. This allows control over the tilt angle between the web plate 2 and the ground, thereby achieving initial positioning of the web plate 2.

[0046] Optionally, in step S2, if the length of the web plate 2 exceeds 3m, a first pad 4 is placed at the middle position of the web plate 2 along its length to support it. It is understood that since the length of the web plate 2 exceeds 3m, it is prone to bending and deformation after being pried up, causing the end of the web plate 2 in contact with the mounting line 11 to bend. This results in the end of the web plate 2 in contact with the mounting line 11 not being aligned with it. By adding the first pad 4, the sinking deformation of the web plate 2 can be effectively prevented, thus ensuring that the end of the web plate 2 in contact with the mounting line 11 remains straight.

[0047] Optionally, in step S4, the perpendicularity of the web plate 2 and the panel 1 is checked using a square. If the perpendicularity requirement is not met, the web plate 2 is finely adjusted using a pry bar 3 to make it perpendicular to the panel 1. It can be understood that if the perpendicularity requirement is not met, the two ends of the web plate 2 are first welded to the panel 1 to initially fix the web plate 2 to the panel 1. Then, a square is placed at the connection point between the web plate 2 and the panel 1 to initially determine the tilt angle between the web plate 2 and the panel 1. The web plate 2 is then tapped from one side or screwed down using the pry bar 3 to adjust its position. After adjustment, the perpendicularity of the web plate 2 and the panel 1 is re-measured using a square until the web plate 2 is perpendicular to the panel 1.

[0048] Optionally, one end of the pry bar 3 is provided with a pry blade 31, and the other end is provided with a slot 32, into which both the panel 1 and the web 2 can be inserted. The pry blade 31 facilitates the prying up of the web 2 and the panel 1. Furthermore, as... Figure 5 As shown, the pry bar 31 in this embodiment is wedge-shaped to facilitate inserting it into the gap between the web plate 2 and the ground, and between the panel 1 and the ground. The slot 32 facilitates adjusting the perpendicularity of the web plate 2 and the panel 1 using the pry bar 3. It is understood that in this embodiment, when the perpendicularity requirement between the web plate 2 and the panel 1 is not met, by inserting one side of the web plate 2 into the slot 32 and then twisting the pry bar 3, a torque is generated on the web plate 2, causing it to rotate slightly around the end in contact with the mounting line 11, thereby adjusting the perpendicularity of the web plate 2 to the panel 1.

[0049] Optionally, such as Figure 7 As shown, the second pad 5 is wedge-shaped, which facilitates the support of the panel 1. Furthermore, in this embodiment, the second pad 5 is made of iron, thereby ensuring high support force for the panel 1 to meet the requirements for the stability of the panel 1.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
