Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a joint practice for an internal rainwater pipe penetrating into a steel pipe column. Background Art

[0002] For organized drainage on the roof, it generally drains to the underground drainage pipe through a rainwater pipe after being collected. The rainwater pipe is connected from the roof to the ground all the way, and it is necessary to ensure smooth drainage. The rainwater pipe is generally designed to be exposed or hidden through measures such as setting pipe wells and decorative wrapping. However, for large-space buildings such as museums, the interior decoration requirements are high, and it is difficult to arrange the rainwater pipe.

[0003] In view of the above defects, in the prior art, horizontal conversion branch pipes are generally set to collect rainwater uniformly into the pipe well. However, in this method, the drainage path is long, which affects the building's net height, generates noise. At the same time, steel pipe columns or concrete-filled steel pipe columns are also set, with internal rainwater pipes. However, the disadvantage of this kind of internal rainwater pipe is that the rainwater pipe mostly penetrates vertically from the top of the column. For the roof with a gutter, the beam-column joint cannot be normally connected, posing a safety hazard.

[0004] Therefore, we propose a joint practice for an internal rainwater pipe penetrating into a steel pipe column to solve the above problems. Summary of the Invention

[0005] In view of the problems existing in the prior joint practice for an internal rainwater pipe penetrating into a steel pipe column, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide a joint practice for an internal rainwater pipe penetrating into a steel pipe column, which solves the problem that the existing roof organized drainage requires measures such as setting pipe wells and decorative wrapping below or outside the rainwater pipe, and is relatively difficult to arrange.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: A joint practice for an internal rainwater pipe penetrating into a steel pipe column, including a top beam, a steel pipe column fixedly arranged at the bottom of the top beam, and a rainwater pipe. A rectangular hole is opened at the upper end of the outer wall of the steel pipe column. The rainwater pipe is arranged inside the steel pipe column, and a rainwater pipe elbow is connected to the upper end. The rainwater pipe elbow is arranged inside the rectangular hole; A channel-shaped stiffening plate is fixedly arranged at the upper end of the outer wall of the steel pipe column. A sealing plate is fixedly arranged on the inner wall of the rectangular hole. A sealing stiffening plate is fixedly arranged at the bottom of the channel-shaped stiffening plate.

[0008] Preferably, the top of the sealing plate is arc-shaped and is in contact and cooperation with the outer wall of the rainwater pipe elbow.

[0009] Preferably, an operation chamber is formed on the front side of the plugging plate. Two symmetrically arranged through holes are formed in the top of the operation chamber. A limiting strap is inserted through the two through holes and covers the outer wall of the rainwater pipe elbow. The lower end of the limiting strap is located in the operation chamber, and an adjusting and limiting mechanism is arranged between the limiting strap and the operation chamber.

[0010] Preferably, the adjusting and limiting mechanism includes an adjusting screw rod. The adjusting screw rod is rotatably arranged at the bottom of the inner wall of the operation chamber. A sliding block is sleeved on the rod wall of the adjusting screw rod in a threaded manner. The lower end of the limiting strap is fixedly connected to the sliding block. The back side of the sliding block is in contact and cooperation with the rear side of the inner wall of the operation chamber. A rotating block is fixedly sleeved on the lower end of the rod wall of the adjusting screw rod.

[0011] Furthermore, the inner sides of the two through holes are both provided with rounded corners.

[0012] Preferably, a cover plate is hinged to the lower end of the front side of the plugging plate. Two symmetrically arranged connecting bolts are threadedly inserted into the interior of the cover plate. The connecting bolts are in threaded connection and cooperation with the plugging plate.

[0013] Preferably, the channel-shaped stiffening plate, the plugging plate, and the sealing stiffening plate are fixedly connected by welding.

[0014] Specific implementation process: First step, place the rainwater pipe inside the steel pipe column, extend the rainwater pipe elbow out of the rectangular hole, and clamp the lower edge of the rectangular hole, while the end of the rainwater pipe extends into the bottom of the steel pipe column. At this time, the rainwater pipe and the steel pipe column are radially fixed, and check for any potential for detachment. If there is a potential for detachment, adjust the position of the rainwater pipe. If there is no potential, proceed to the next step; Second step, when the position of the rainwater pipe is determined and there is no potential, start hoisting, temporarily fix the steel pipe column and the lower section column, and leave a 20 - centimeter space. Then fix the position of the rainwater pipe, simultaneously release the temporary digital display fixation of the steel pipe column, and slowly lower it to dock with the lower section column, and check the perpendicularity of the steel pipe column 1. If it is unqualified, adjust the steel pipe column and refix it. If it is qualified, continue to the next step; Third step, weld the steel pipe column, weld the arc-shaped plugging plate to block the rectangular hole, then weld the sealing stiffening plate to strengthen and fix the rectangular hole, and finally complete the overall operation. In the above technical solution, the technical effects and advantages provided by the present invention: In the present invention, by internally inserting the rainwater pipe into the steel pipe column, there is no need to set up complex measures such as pipe wells and decorative wrapping below or outside the rainwater pipe, solving the problem of difficult layout of rainwater pipes in large - space buildings. At the same time, this design shortens the drainage path, reduces the noise generated during the drainage process, also reduces the impact on the building's net height, and improves the utilization efficiency and comfort of the building space.

[0015] In the present invention, by providing a channel-shaped stiffening plate, a sealing plate and a sealing stiffening plate, the structural strength at the opening of the steel pipe column is effectively enhanced.

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail with reference to the drawings.

[0020] The embodiments of the present invention disclose a node practice for an internal rainwater pipe to penetrate a steel pipe column.

[0021] The present invention provides as Figures 1-6A node practice for an internal rainwater pipe passing through a steel pipe column as shown includes a top beam 1, a steel pipe column 2 fixedly arranged at the bottom of the top beam 1, and a rainwater pipe 3. A rectangular hole 4 is opened at the upper end of the outer wall of the steel pipe column 2. The rainwater pipe 3 is arranged inside the steel pipe column 2, and a rainwater pipe elbow 5 is communicated and arranged at the upper end. The rainwater pipe elbow 5 is arranged in the rectangular hole 4; A channel-shaped stiffening plate 6 is fixedly arranged at the upper end of the outer wall of the steel pipe column 2. A sealing plate 7 is fixedly arranged on the inner wall of the rectangular hole 4. A sealing stiffening plate 8 is fixedly arranged at the bottom of the channel-shaped stiffening plate 6. The top of the sealing plate 7 is arc-shaped and is in contact and cooperation with the outer wall of the rainwater pipe elbow 5. The channel-shaped stiffening plate 6, the sealing plate 7, and the sealing stiffening plate 8 are welded and fixed.

[0022] During the operation of the building drainage system, rainwater is collected into the rainwater pipe 3 through the drainage system on the roof. Since the rainwater pipe 3 is arranged inside the steel pipe column 2 and the rainwater pipe elbow 5 at its upper end is located in the rectangular hole 4 opened at the upper end of the outer wall of the steel pipe column 2, the rainwater can change the flow direction through the rainwater pipe elbow 5 and smoothly drain downward along the rainwater pipe 3. The settings of the channel-shaped stiffening plate 6, the sealing plate 7, and the sealing stiffening plate 8 enhance the structural strength at the opening of the steel pipe column 2. The channel-shaped stiffening plate 6 is fixed at the upper end of the outer wall of the steel pipe column 2 and plays a role in strengthening the steel pipe column 2. The sealing stiffening plate 8 is located at the bottom of the channel-shaped stiffening plate 6 to further enhance the stability of the overall structure. The sealing plate 7 is fixed on the inner wall of the rectangular hole 4. On the one hand, it prevents rainwater from leaking through the rectangular hole 4. On the other hand, it works together with the channel-shaped stiffening plate 6 and the sealing stiffening plate 8 to ensure the mechanical properties of the steel pipe column 2 after the opening.

[0023] In order to stably cooperate the rainwater pipe 3 with the sealing plate 7 according to the specifications of the rainwater pipe 3, facilitate the installation of the sealing plate 7 inside the steel pipe column 2 and cooperate with the rectangular hole 4 to stably clamp and position the rainwater pipe 3, and ensure the stable setting position of the rainwater pipe 3, as Figure 2 and Figures 4-5 shown, an operation chamber is opened on the front side of the sealing plate 7. Two symmetrically arranged through holes 9 are opened at the top of the operation chamber. The inner sides of the two through holes 9 are both chamfered. A limiting binding strap 10 is commonly passed through the two through holes 9. The limiting binding strap 10 covers the outer wall of the rainwater pipe elbow 5. The lower end of the limiting binding strap 10 is located inside the operation chamber, and an adjusting and limiting mechanism is arranged between the limiting binding strap 10 and the operation chamber. The adjusting and limiting mechanism includes an adjusting screw 11. The adjusting screw 11 is rotatably arranged at the bottom of the inner wall of the operation chamber. A slider 12 is sleeved on the rod wall of the adjusting screw 11 in a threaded manner. The lower end of the limiting binding strap 10 is fixedly connected with the slider 12. The back side of the slider 12 is in contact and cooperation with the rear side of the inner wall of the operation chamber. A rotating block 13 is fixedly sleeved at the lower end of the rod wall of the adjusting screw 11. A cover plate 14 is hinged at the lower end of the front side of the sealing plate 7. Two symmetrically arranged connecting bolts 15 are threadedly passed through the inside of the cover plate 14. The connecting bolts 15 are in threaded connection and cooperation with the sealing plate 7.

[0024] When installing the rainwater pipe 3, first insert the rainwater pipe 3 into the steel pipe column 2, and place the rainwater pipe elbow 5 in the rectangular hole 4. At this time, fix the rainwater pipe 3 by adjusting the limit mechanism. Rotate the rotating block 13, and the rotating block 13 drives the adjusting screw 11 to rotate. Since the slider 12 is threadedly connected to the adjusting screw 11, and the back side of the slider 12 is in contact and cooperation with the rear side of the inner wall of the operation chamber, the slider 12 will move back and forth along the inner wall of the operation chamber under the drive of the adjusting screw 11. When the slider 12 moves, it drives the limit binding strap 10 fixedly connected thereto to move. The limit binding strap 10 passes through the through hole 9 at the top of the operation chamber and covers the outer wall of the rainwater pipe elbow 5. By adjusting the position of the limit binding strap 10, a suitable binding force is generated on the rainwater pipe elbow 5, so as to stably fix the rainwater pipe 3 in the steel pipe column 2. The inner side of the through hole 9 is provided with a chamfer to prevent the limit binding strap 10 from being scratched at the through hole 9 and extend its service life.

[0025] The specific method is as follows: During the installation process, a certain relative displacement between the rainwater pipe 3 and the rainwater pipe elbow 5 and the steel pipe column 2 is allowed. That is, during installation, first place the rainwater pipe 3 and the rainwater pipe elbow 5 on the steel pipe column 1, and then hoist the upper assembly. After hoisting, make the rainwater pipe elbow 5 located at the lower edge of the rectangular hole 4, and make the rainwater pipe 3 expose from the lower end of the steel pipe column 2, and carry out the butt joint construction of the rainwater pipe 3. After the butt joint of the rainwater pipe 3 is completed and inspected qualified, then lower the steel pipe column 1 to connect the steel pipe column 1 with the lower steel pipe. After the steel pipe connection is completed, the rainwater pipe elbow 5 will be at the upper edge of the rectangular hole 4. Subsequently, a channel-shaped stiffening plate 6 is provided at the upper edge of the rectangular hole 4. After the connection of the rainwater pipe 3 and the steel pipe column 1 is completed, the rainwater pipe elbow 5 will be within the range of the channel-shaped stiffening plate 6. A sealing plate 7 is installed in the gap between the rainwater pipe elbow 3 and the lower edge of the rectangular hole 4, and the position of the rainwater pipe elbow 5 is set by bundling the sealing plate 7 and the limit binding strap 10. Finally, a sealing stiffening plate 8 is provided at the opening of the channel-shaped stiffening plate 6. The sealing stiffening plate 8 is welded to the channel-shaped stiffening plate 6, the steel pipe column 1 and the sealing plate 7.

[0026] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
