Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a drainage structure of a node between a ceramic brick curtain wall and a parapet. Background Art
[0002] Curtain walls are a commonly used lightweight, decorative wall structure for the exterior of a building. Ceramic brick curtain walls are exterior walls constructed from ceramic bricks, typically made from high-quality clay, purple clay, and other raw materials, and fired at high temperatures. Compared to traditional clay bricks, ceramic bricks offer a finer texture, more stable color, and resistance to high temperatures and corrosion, making them more practical. Parapets, on the other hand, are low walls surrounding a building's roof. Besides providing safety, they also feature waterproof pressure brick capping at their base to prevent water seepage from the waterproofing layer or rooftop runoff.
[0003] The gaps between the tiles of the ceramic brick curtain wall at the connection with the parapet are facing upward. To ensure the waterproof performance of the ceramic brick curtain wall, the gaps between the tiles are filled with mortar and sealant. In heavy rainfall or after prolonged use, rainwater will seep into the curtain wall through the filled brick gaps, and then into the interior, potentially affecting the insulation and other functions of the exterior wall. However, the ceramic brick curtain wall cannot be directly connected to the rain gutter. Usually, a waterproof steel plate is installed under the ceramic brick curtain wall to connect to the finished rain gutter. The finished rain gutter is made of cast iron and the waterproof steel plate is made of galvanized steel. However, if the welding performance of the two is poor, it is easy to cause construction failure or large gaps. In addition, this method is prone to water accumulation at the waterproof steel plate and water seepage at the gaps in the waterproof steel plate. Therefore, there is an urgent need for a drainage node that can solve the problem of water accumulation at the connection between the ceramic brick curtain wall and the exterior wall. Utility Model Content
[0004] The content of this utility model is used to briefly introduce the concepts that will be described in detail in the detailed description section below. The content of this utility model is not intended to identify the key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.
[0005] In response to the problems and shortcomings of the existing technology, the purpose is to provide a drainage structure for the node between a ceramic brick curtain wall and a parapet. The utility model sets a steel frame on the inner side of the parapet. By connecting the folded drainage board to the steel frame, the problem of water seepage that is easy to occur in the node treatment of the conventional ceramic brick curtain wall and parapet can be solved, so that the drainage is more normal and less prone to water accumulation. The durability is also effectively improved, which is used to solve the technical problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: comprising a parapet and a ceramic tile curtain wall, the parapet being connected to a steel frame, the steel frame comprising a plurality of steel keels, the steel keels being arranged on both sides of the parapet and connected by connectors, steel main beams being connected between opposite steel keels, angle steel beams being connected between adjacent steel main beams, angle steel columns being connected above the angle steel beams, supporting secondary beams being connected between opposite angle steel columns, the top ends of the angle steel columns being connected to the steel keels via a top beam, the top beam, supporting secondary beam, and steel keels being connected to the ceramic tile curtain wall via connectors, the angle steel beams being connected to the folded edges of a folded edge drainage board, and a plurality of drainage holes being provided on the bottom plate of the folded edge drainage board corresponding to the drainage strips of the parapet, and brick joints of the ceramic tile curtain wall having brick joint leaks.
[0007] Preferably, the two opposite angle steel beams are further connected with a secondary structural beam. The connection between the two opposite angle steel beams via the secondary structural beam can improve the stability and firmness of the steel frame, thereby improving safety during use.
[0008] Preferably, the bottom plate of the folded drainage board is inclined toward the parapet drainage strip, and the bottom of the slope of the bottom plate of the folded drainage board is not lower than the lower edge of the steel main beam, and the folded drainage board is connected to the steel main beam. Arranging the bottom plate of the folded drainage board in an inclined state allows rainwater to be quickly drained toward the parapet drainage strip under the action of gravity, thereby improving drainage efficiency.
[0009] Preferably, the bottom plate of the folded drainage board is inclined toward the parapet drainage strip, and both the top and bottom of the slope of the bottom plate of the folded drainage board are lower than the lower edge of the steel main beam. When both the top and bottom of the slope of the bottom plate of the folded drainage board are lower than the lower edge of the steel main beam, there is no weld between the folded drainage board and the steel main beam, thereby improving the overall waterproofing effect.
[0010] Preferably, the inclination gradient of the bottom plate of the folded drainage board is set to be greater than 5° based on the direction perpendicular to the steel keel.
[0011] Preferably, a hole is opened on the bottom plate of the folded drain board to connect a drain pipe. When in use, rainwater can flow from the brick seams left on the ceramic brick curtain wall to the folded drain board, and then flow into the pebble belt or drainage ditch through the drain pipe connected to the folded drain board, making the overall drainage process smoother.
[0012] Preferably, the hem drain board is made of galvanized steel. Galvanized steel is a welded steel plate with a hot-dip or electroplated zinc layer on the surface. Since galvanized steel has excellent corrosion resistance, coating properties, and good weldability, the hem drain board made of galvanized steel can effectively improve its waterproof performance and extend its overall service life.
[0013] Preferably, a drainage pipe is connected to a rain gutter below the brick joint leak. During use, rainwater can flow from the brick joint leak in the ceramic tile curtain wall into the rain gutter, then through the drainage pipe into the pebble belt or drainage ditch inside the parapet. The rain gutter and drainage pipe can be pre-purchased, which improves convenience.
[0014] Preferably, the rainwater gutter and drain pipe are both made of galvanized steel. Using the same galvanized steel as the hem drain panels allows both the ceramic tile curtain wall and the hem drain panels to be constructed by a dedicated curtain wall team, eliminating the need for overlapping processes and facilitating construction. Furthermore, using the curtain wall detailed drawings can reduce omissions. This also further enhances overall waterproofing performance.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] This utility model has a simple structure and is easy to install and connect. It can significantly improve the drainage efficiency of the parapet joints of a ceramic tile curtain wall and reduce the problem of water accumulation. In this utility model, a steel frame is fixedly connected to both sides of the parapet using connectors. Connectors also securely connect the steel frame to the ceramic tile curtain wall, and a hem drain plate is connected below the steel frame. During use, rainwater can flow from the leaking brick joints in the ceramic tile curtain wall to the hem drain plate, then through the drainage holes in the hem drain plate into the pebble strip or drainage ditch inside the parapet. Alternatively, rainwater can flow from the leaking brick joints into the rainwater gutter before flowing into the drain pipe, and from there into the pebble strip or drainage ditch inside the parapet wall. This effectively solves the problem of water seepage into the interior without affecting the exterior wall's insulation function. Furthermore, both the rainwater gutter and the hem drain plate are made of galvanized steel, effectively improving the waterproof performance after welding and reducing the problem of water seepage and leakage.

[0027] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.
[0028] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. Example 1
[0029] This embodiment provides a drainage structure for the node between a ceramic brick curtain wall and a parapet wall, such as Figure 1 and Figure 5 As shown: it includes a folded drainage board 1, a ceramic brick curtain wall 2, a steel frame 3 and a parapet 7, wherein the steel frame 3 is connected to the parapet 7, and the steel frame 3 includes a steel keel 301, a steel main beam 302, an angle steel beam 303, an angle steel column 304, a structural secondary beam 305, a supporting secondary beam 306 and a top beam 307.
[0030] Multiple steel keels 301 are provided and positioned on both sides of the parapet 7. They are fixedly connected to the parapet 7 via steel connectors and embedded plates, with a spacing of 2 meters between the steel keels 301 and the parapet 7. Two opposing steel keels 301 are connected via a steel main beam 302, while two adjacent steel main beams 302 are connected via an angle steel beam 303. The angle steel beams 303 are symmetrically arranged on both sides, and the angle steel beams 303 and the steel main beams 302 are connected perpendicularly to each other. Angle steel columns 304 are connected above the angle steel beams 303 on both sides, and the spacing of the angle steel columns 304 is designed according to project requirements. The two angle steel beams 303 are connected via a structural secondary beam 305, and a supporting secondary beam 306 is provided between the two angle steel columns 304. The supporting secondary beam 306, the angle steel columns 304, and the steel main beams 302 perpendicular to the sides of the steel keels 301 are connected to form a concave frame. The tops of the angle steel columns 304 are connected to the steel keels 301 on either side via a top beam 307. A ceramic brick curtain wall 2 is then laid above the top beam 307 and the supporting secondary beam 306. The various types of ceramic bricks are connected by their own through-steel bars to form the ceramic brick curtain wall 2. The ceramic brick curtain wall 2 is then connected to the top beam 307 and the supporting secondary beam 306 via connecting clips. The gaps in the ceramic brick curtain wall 2 are then filled with mortar, and the outer openings of the gaps are sealed with sealing strips or sealant. In particular, the brick joints in the groove where the ceramic brick curtain wall 2 meets the supporting secondary beam 306 are not filled, leaving an open gap as the brick joint outlet 5 corresponding to the hem drain board 1. Unless otherwise specified, all parts of the steel frame 3 are connected and secured using welds.
[0031] The folded drain board 1 is connected to the steel frame 3. Specifically, the folded edges extending upward on both sides of the folded drain board 1 are connected to the angle steel beam 303, that is, the folded drain board 1 is located below the angle steel beam 303. Figure 7 As shown, the bottom plate of the hem drain board 1 is provided with multiple drainage holes spaced apart at intervals. The drainage holes can be square or circular in shape. Furthermore, the hem drain board 1 is made of galvanized steel sheet with a thickness of no less than 1.2 mm. With the direction perpendicular to the steel keel 301 as the reference line, the bottom plate of the hem drain board 1 is tilted toward the drainage strip inside the parapet 7. This drainage strip is a pebble strip or drainage ditch, and the inclination angle is set to be greater than 5°. It should be noted that in this embodiment, the bottom of the slope of the bottom plate of the hem drain board 1 must not be lower than the lower edge of the steel main beam 302. The hem drain board 1 and the steel main beam 302 are then connected by welds. During use, rainwater can flow from the brick seam leaks 5 left in the ceramic tile curtain wall 2 onto the hem drain board 1, then flow through the drainage holes in the hem drain board 1 into the pebble strip or drainage ditch inside the parapet 7. Example 2
[0032] like Figure 2As shown, the difference between this embodiment and embodiment 1 lies in the setting method of the folded drain board 1. Specifically, the top of the slope of the bottom plate of the inclined folded drain board 1 is lower than the steel main beam 302 perpendicular to the direction of the steel keel 301, and the other requirements are the same as those of embodiment 1. Compared with embodiment 1, the top and bottom of the bottom plate of the folded drain board 1 are lower than the lower edge of the steel main beam 302, so there is no weld between the folded drain board 1 and the steel main beam 302, thereby improving the overall waterproof effect. Among them, the front view of the folded drain board 1 is as shown Figure 8 shown. Example 3
[0033] like Figure 3 As shown, the folded drain board 1 in this embodiment can be set with reference to the embodiment 1 or embodiment 2, and the difference between this embodiment and the above embodiment is that the drainage holes set at intervals on the bottom plate of the folded drain board 1 are replaced with connecting drain pipes 4. Figure 9 The figure shows a front view of the connection between the folded drain board 1 and the drain pipe 4. Rainwater can flow from the brick seam leak 5 left on the ceramic brick curtain wall 2 to the folded drain board 1, and then flow into the pebble belt or drainage ditch through the drain pipe 4 connected to the folded drain board 1. Example 4
[0034] like Figure 4 As shown, the folded drainage board 1 in this embodiment can be set with reference to embodiment 1, embodiment 2 or embodiment 3, and the difference between this embodiment and the above embodiment is that a rain gutter 6 is connected below the cracked brick seam leakage 5, and the width of the upper opening of the rain gutter 6 needs to be greater than the crack width of the brick seam leakage 5, such as Figure 6 As shown, the rain gutter 6 is fixedly connected to the steel frame 3 by welding or fasteners. The lower portion of the rain gutter 6 is connected to the drain pipe 4. The lower outlet of the drain pipe 4 leads to the drainage belt inside the parapet 7 or to the hem drain board 1. The rain gutter 6 and drain pipe 4 can be pre-purchased, which improves ease of use. During use, rainwater can flow from the brick joints 5 in the ceramic tile curtain wall 2 into the rain gutter 6, then through the drain pipe 4 into the pebble belt or drainage ditch inside the parapet 7. Example 5
[0035] This embodiment is a modification of Examples 3 and 4. The rain gutter 6 and drain pipe 4 can also be made of the same galvanized steel sheet as the hem drain board 1, fabricated according to actual project requirements. This ensures excellent weldability and reduces the risk of leaks. During construction, the rain gutter 6 and drain pipe 4 are constructed by a specialized water supply and drainage team, while the ceramic tile curtain wall 2 and hem drain board 1 are constructed by a specialized curtain wall team. This can lead to overlapping construction processes, making it difficult to construct. Furthermore, drainage nodes can be omitted from the drawings or impossible to construct. For example, weldability between a finished cast iron rain gutter and the galvanized steel hem drain board 1 is difficult, easily leading to leaks at the rain gutter 6 nodes. By fabricating the rain gutter 6 and drain pipe 4 from the same galvanized steel sheet as the hem drain board 1 according to actual project requirements, both the ceramic tile curtain wall 2 and the hem drain board 1 can be constructed by a specialized curtain wall team, eliminating overlapping processes and facilitating construction. Furthermore, when the hem drain board 1 is constructed by a curtain wall unit, detailed curtain wall drawings are used to minimize omissions.
[0036] In the description of the present invention, it should be understood that the indicated orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0037] In addition to the above embodiments, the present invention may also have other implementation methods. For those skilled in the art, it is still possible to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
