Description

Technical Field

[0001] The invention belongs to the field of drainage pipes, in particular to a beam-column steel ring plate node structure and a manufacturing method thereof for facilitating vertical drainage. Background Art

[0002] At present, the drainage of roofs is generally carried out in the following way, that is, drainage ditches are set up on the roof to collect rainwater on the roof, and drain it to the ground through vertical water pipes. If the vertical water pipes are set on the outside of the building, it will be very unsightly; if the vertical water pipes are set on the inside of the building, they will generally be close to the edge of the column for aesthetic reasons and wrapped with decoration materials. However, steel structures often have steel ring plates at the joints of beams and columns with larger spans. The steel ring plates will protrude a certain distance from the outside of the column, causing the vertical drainage pipes to collide with them. If the drainage pipes pass directly through the steel ring plates, it will cause problems with the structural safety. If the position of the drainage pipes is moved to the outside of the steel ring plates, it will be very unsightly and affect the indoor space. See for details. Figure 1 and Figure 2 . Summary of the Invention

[0003] The present invention provides a beam-column steel ring plate node structure that facilitates vertical drainage. The structure is located inside the steel ring plate and has a good force transmission structure, which can solve the unsightly drainage pipe and the unsafe problem caused by penetrating the steel ring plate.

[0004] The present invention specifically adopts the following technical means:

[0005] A beam-column steel ring plate node structure that facilitates vertical drainage includes a steel column and an outer steel ring plate. A water pipe penetrates the steel ring plate and is integrally formed with it. A steel plate is welded inside the water pipe, and a triangular steel plate is welded to the outside of the water pipe corresponding to the steel plate. The water pipe is externally connected to a detachable water pipe.

[0006] Furthermore, the steel ring plate includes an upper flange of the steel ring plate and a lower flange of the steel ring plate, and the water pipe penetrates the upper and lower flanges of the steel ring plate at the same time.

[0007] Furthermore, the triangular steel plate is welded between the flange of the steel ring plate and the water pipe.

[0008] Furthermore, a tongue and groove adapted to the end of an adjacent water pipe is provided at the water pipe interface, and the water pipe is connected to the detachable water pipe through the tongue and groove.

[0009] Furthermore, adjacent detachable water pipes are connected via tongue and groove.

[0010] Furthermore, the tongue and groove at the interface includes an outer tongue and an inner tongue combined therewith, the protruding portion of the outer tongue and groove is located outside the water pipe, and the protruding portion of the inner tongue and groove is located inside the water pipe; the protruding portion of the outer tongue and groove has a certain slope.

[0011] Furthermore, a spring is provided between the tongue and groove, and the spring is located inside the interface.

[0012] Furthermore, water-swellable rubber is provided at the tongue-and-groove gap.

[0013] In addition, the present invention also provides a beam-column steel ring plate node method that facilitates vertical drainage, comprising the following steps:

[0014] Step 1: Open holes in the steel ring plates of beams and columns, insert water pipes into the steel ring plates, weld steel plates inside the water pipes, and weld triangular steel plates outside the water pipes corresponding to the steel plates to form a water pipe structure integrated with the steel ring plates;

[0015] Step 2: Splice the detachable water pipes with the water pipes up and down. When splicing, first fix the spring beside the outer tongue and groove and apply a circle of water-swelling rubber on the surface of the tongue and groove. Then insert the inner tongue and groove into the outer tongue and groove to achieve splicing between the water pipes.

[0016] Furthermore, the water pipe structure integrated with the steel ring plate can also be prefabricated in a factory.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This structure is installed inside the steel ring plate of the beam and column, without affecting the interior space and aesthetics. A steel plate is set at the corresponding position of the upper and lower flanges of the steel ring plate, which can be used to transmit the force of the steel beam flange. Even if there are holes on the flange, the force transmission effect will not be affected; a triangular steel plate aligned with it is welded on the outside of the steel plate to make the force transmission smoother, thereby improving the safety of the entire structure. The water pipe interface is designed with a tongue and groove for connection. The protruding part of the inner tongue and groove is located on the inside of the water pipe, and the protruding part of the outer tongue and groove is on the outside of the water pipe. The above method can effectively prevent water from seeping into the outside of the pipe during falling water. The protruding part of the tongue and groove is made at a certain slope to facilitate the assembly of the water pipe. After the detachable water pipe is installed on site, it can be used directly, which is convenient for disassembly and cleaning garbage in the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] See also Figure 3 A beam-column steel ring plate 3 node structure facilitates vertical drainage. The steel ring plate 3 is set on the periphery of the steel column 1, with its edge protruding outward. The steel ring plate 3 is welded to the steel beam 2. A water pipe 4 passes through the steel ring plate 3, which is welded to a steel plate 6 inside and a triangular steel plate 8 outside. The steel plates 6 and 8 are aligned to facilitate force distribution.

[0029] See also Figure 4 , a cross-sectional view taken along node BB of the water pipe 4 and the steel ring plate 3, shows the upper and lower steel ring plates 3 with outwardly projecting flanges. The water pipe 4 passes through both flanges. Two steel plates 6 are welded inside the water pipe 4, located at corresponding positions on the upper flange 31 and lower flange 32 of the steel ring plate. The lower end of the water pipe 4 is connected to the upper end 51 of the detachable water pipe via a tongue-and-groove 7, while the upper end of the water pipe 4 is connected to the lower end 52 of the detachable water pipe via a tongue-and-groove 7.

[0030] See also Figure 5 The upper and lower ends of the water pipe each protrude 100-150mm above the upper and lower flanges, protruding above the building surface to facilitate future disassembly and installation. The junction of the water pipe 4 with the upper and lower flanges forms a right angle. Triangular steel plates 8 are welded to the upper and lower flange surfaces and the outside of the water pipe 4, forming a single piece of steel ring plate 3 and the water pipe 4. To ensure smoother force transmission, the welded triangular steel plates 8 are aligned with the steel plates 6 inside the water pipe.

[0031] See also Figure 6 and 7 , respectively, show the connection details of the upper and lower ends of the steel ring plate 3. The tongue and groove 7 at the interface consists of an outer tongue and groove 71 and an inner tongue and groove 72. The protruding portion of the outer tongue and groove 71 is located outside the water pipe 4, while the protruding portion of the inner tongue and groove 72 is located inside the water pipe 4. This effectively prevents water from seeping into the outside of the pipe during a fall. The protruding portion of the outer tongue and groove 71 has a certain slope to facilitate the installation of the water pipe 4. A circle of water-swelling rubber 10 is placed on the surface of the tongue and groove 7 to ensure a better fit and prevent water from seeping out.

[0032] A spring 9 is fixed inside the upper end of the detachable water pipe 4. When installing the detachable water pipe 4, first insert its upper end into the outer side of the groove 7 of the integrated water pipe 4, compress the spring 9, and at the same time, allow the lower end 52 of the detachable water pipe to be inserted into the inner side of the groove 7 of the integrated water pipe 4. Then, the detachable water pipe 5 is automatically positioned and fixed under the force of gravity and the compression of the spring 9. When removing, lift the upper end of the detachable water pipe 4 to compress the spring 9 and remove it.

[0033] This implementation also provides a beam-column steel ring plate three-node structure method that facilitates vertical drainage:

[0034] Holes are opened in the beam-column steel ring plate 3, and the water pipe 4 is passed through the steel ring plate 3. Steel plates 6 are welded inside the water pipe 4, and triangular steel plates 8 are welded outside the water pipe 4 corresponding to the steel plates 6 to form a water pipe 4 structure integrated with the steel ring plate 3;

[0035] The detachable water pipe 5 and the water pipe 4 are spliced ​​up and down. When splicing, first fix the spring 9 beside the outer tongue and groove 71 and apply a circle of water-swelling rubber 10 on the surface of the tongue and groove 7, and then insert the inner tongue and groove 72 into the outer tongue and groove 71 to realize the splicing between the water pipes 4.
