Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated structure of snow melting board and drainage ditch and its construction method. Background Technology

[0002] Drainage gutters are installed on the roofs of large buildings for roof drainage. In northern regions, especially in frigid areas, snow melting measures are typically implemented within the roof drainage gutters to prevent secondary icing caused by difficulties in snow melting after winter snowfall. The most common snow melting method involves installing snow melting boards within the drainage gutters. The traditional approach is to first construct the drainage gutters, then apply a waterproofing layer within them, and finally install the snow melting boards and cables. However, this method requires completion of the roof construction, necessitating the entire snow melting system installation on the roof. This involves significant work at height, posing safety hazards, and is also time-consuming and inefficient.

[0003] Therefore, how to create a prefabricated structure for snow melting boards and drainage ditches and its construction method is one of the important research and development topics at present. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a prefabricated structure for snow melting boards and drainage ditches, which integrates the snow melting boards and drainage ditches before the construction of the drainage ditches, reduces the amount of high-altitude work, provides construction safety, and also improves construction quality and efficiency, thereby overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides an assembled structure of snow melting board and drainage ditch, characterized in that it includes a drainage ditch, a mounting base, a snow melting board, a cable bracket and a branch cable. Several mounting bases are provided along the length of the drainage ditch for installing snow melting boards; The mounting base is a hollow rectangular shell with an open top. The snow melting plate is rectangular and has horizontally outward-extending wing plates on the front and rear sides of the top. The mounting base and the wing plates of the snow melting plate are connected by a limiting clip. The limiting clip has an inverted L-shaped cross-section. Both the vertical and horizontal end faces have inwardly recessed slots. The front and rear side walls of the mounting base and the wing plates on both sides of the snow melting plate are inserted into the slots of the limiting clip to achieve a snap-fit ​​connection. The snow melting plate has an inwardly recessed power interface and a control interface on its left and right side walls, respectively. One end of the branch cable is electrically connected to the power interface or control interface of the snow melting board, and the other end is left outside. The cable bracket is installed inside the mounting base and located on the left and right sides of the snow melting board. The cable bracket includes an outer protective tube that connects to the power interface or control interface and is sleeved on the outside of the branch cable. The drainage ditch, mounting base, snow melting board, cable bracket and branch cable are integrated into one unit before the drainage ditch is installed to the roof, and the snow melting board, mounting base and outer protective pipe are wrapped inside when the waterproof layer of the drainage ditch is constructed.

[0006] As an improvement of the present invention, the depth of the mounting base is greater than the thickness of the snow melting plate, so that there is a gap between the bottom of the snow melting plate and the mounting base.

[0007] Furthermore, the mounting base is made of heat-insulating material, or has a heat-insulating material coating on its surface.

[0008] Furthermore, the mounting base is fixed to the drainage ditch by welding or bonding.

[0009] Furthermore, two first cover plates are provided above the mounting base on the left and right sides of the snow melting plate. The first cover plates have square grooves for extending the cable bracket out of the first cover plate and for limiting the cable bracket.

[0010] Furthermore, the cable bracket also includes a main line bracket, which is a horizontally arranged T-shaped tee cable trough. The outer protective tube is connected to the bottom of the main line bracket and communicates with the inside of the main line bracket.

[0011] Furthermore, the main line bracket is provided with a second cover plate at the top, the side wall of the main line bracket is provided with an upward protrusion at the top, and the bottom of the second cover plate is provided with a groove. The main line bracket and the second cover plate are connected by the protrusion engaging into the groove.

[0012] Furthermore, terminal plugs and terminal interfaces are respectively provided at both ends of the branch cable. The terminal plugs are inserted into the power interface or control interface of the snow melting plate, and the terminal interfaces are reserved on the outside for connection with the main cable of the power cable or control cable.

[0013] Furthermore, the outer protective tube is L-shaped, with the vertical part connected to the bottom of the main line support and the horizontal part connected to the power interface or control interface of the snow melting board. The height of the vertical part is greater than the thickness of the waterproof layer of the drainage ditch, so that the lower part of the horizontal and vertical parts of the outer protective tube are wrapped in the waterproof layer, while the upper part of the vertical part and the main line support are exposed outside the waterproof layer.

[0014] In addition, the present invention provides a construction method that enables the installation and wiring of snow melting boards and drainage ditches to be completed during the pre-assembly stage in the factory, reducing the amount of high-altitude work, improving construction safety, and also improving construction quality and efficiency, thereby overcoming the shortcomings of the prior art.

[0015] To solve the above-mentioned technical problems, the present invention provides a construction method, which uses the above-mentioned prefabricated structure of snow melting board and drainage ditch for construction, and the specific steps include: 1. Fabricate drainage ditches, mounting bases, snow melting boards, and cable brackets according to the design drawings; S2. Fix several mounting bases in the drainage ditch according to the design position, and the connection method is welding or bonding. S3. Install the snow melting plate on each mounting base using the limit clip; S4. Install cable brackets and connect a branch cable to the power interface and control interface of each snow melting board. The branch cables are run through the outer protective tube. The terminal plugs of the branch cables are inserted into the power interface or control interface of the snow melting board. The terminal interfaces of the branch cables are left outside and placed on the cable brackets. After the cable brackets and branch cables are installed, cover them with the first cover plate. S5. Transport the integrated drainage ditch, mounting base, snow melting board, cable bracket and branch cable together to the construction site, and hoist them to the designed position on the roof for installation; S6. A waterproof layer is constructed inside the drainage ditch. The waterproof layer covers the snow melting board, the mounting base, and the lower part of the horizontal and vertical sections of the outer protective pipe. The upper part of the vertical section of the outer protective pipe and the main line support are exposed outside the waterproof layer. S7. Lay the main power cable and control cable on the two rows of cable brackets, and connect the reserved terminal interface of each branch cable to the pre-made plug on the main cable to realize the parallel connection of each branch cable to the main cable; S8. Install a second cover plate above each cable bracket.

[0016] With this design, the present invention has at least the following advantages: 1. Snow melting boards and drainage ditches are installed on the ground, with terminal interfaces reserved for connection to power cables and control cables. After the construction of the drainage ditch itself and waterproofing is completed, only the main cables of the power cables and control cables need to be laid to complete the construction of the snow melting system, reducing the amount of high-altitude work and improving construction safety. 2. The pre-assembly of snow melting boards and drainage ditches is carried out on the ground, which is easier to operate and ensures better construction quality compared to the traditional high-altitude installation of snow melting boards. 3. The snow melting boards and drainage ditches are integrated in the factory and transported together to the site for installation. This results in less on-site work, a shorter construction period, and higher construction efficiency. 4. The safety base and the snow melting board are connected only by a limit clip, resulting in a small contact area. At the same time, a heat insulation material coating is applied to the surface of the mounting base to prevent cold bridging and condensation at the bottom of the drainage ditch when the snow melting board generates heat during operation.

[0030] Please see Figures 1 to 10 This invention provides an assembled structure for a snow melting board and a drainage ditch, including a drainage ditch 1, a snow melting board 2, a cable bracket 3, a mounting base 7, and branch cables. During the pre-assembly stage at the factory, the drainage ditch 1, the snow melting board 2, the cable bracket 3, the mounting base 7, and the branch cables are integrated into one unit.

[0031] The drainage ditch 1 has several mounting bases 7 arranged along its length inside, and a snow melting plate 2 is mounted on each mounting base 7. The mounting bases 7 are fixedly connected to the drainage ditch 1, and the connection method is selected according to the material of the drainage ditch, either by welding or by bonding. If the drainage ditch 1 is made of metal, the mounting bases 7 are welded inside the drainage ditch 1; if the drainage ditch 1 is made of marble, marble-specific adhesive is used to bond the mounting bases 7 to the drainage ditch 1.

[0032] The mounting base 7 is a hollow rectangular shell with an open top. The snow melting plate 2 is rectangular and has horizontally extending wing plates 4 on both sides of its top edge. The mounting base 7 and the wing plates 4 of the snow melting plate 2 are connected by a limiting clip 8. The limiting clip 8 has an inverted L-shaped cross-section, with inwardly recessed grooves on both the vertical and horizontal end faces. During installation, the front and rear side walls of the mounting base 7 are inserted into the grooves on the vertical end face of the limiting clip 8, and the wing plates 4 of the snow melting plate 2 are inserted into the grooves on the horizontal end face of the limiting clip 7, thereby achieving a snap-fit ​​connection.

[0033] Preferably, the depth of the mounting base 7 is greater than the thickness of the snow melting plate 2, creating a gap between the bottom of the snow melting plate 2 and the mounting base 7. Additionally, the mounting base 7 is made of heat-insulating material or has a heat-insulating coating on its surface.

[0034] This design is because when the drainage ditch 1 is made of metal, the heat generated by the snow melting plate 2 during operation will cause a cold bridge phenomenon, resulting in condensation on the bottom surface of the drainage ditch 1, which will seep into the room. In this embodiment, the solution to this problem is to leave a gap between the mounting base 7 and the snow melting plate 2, and connect them only through the limiting clip 8 to minimize the contact area. Furthermore, the mounting base 7 is insulated to minimize the generation of condensation.

[0035] The snow melting plate 2 has recessed power interface 5 and control interface 6 on its left and right side walls, respectively. The width of the mounting base 7 is greater than the width of the snow melting plate 2. The snow melting plate 2 is installed in the middle of the mounting base 7. The space inside the mounting base 7 located on the left and right sides of the snow melting plate 2 is used to install cable brackets 3.

[0036] Preferably, two first cover plates 14 are provided on the left and right sides of the snow melting plate 2 above the mounting base 7. The two first cover plates 14 and the snow melting plate 2 together seal the top of the mounting base 7 to prevent a large amount of water from flowing into the mounting base 7 when the waterproof layer is damaged.

[0037] The first cover plate 14 has a square groove, which serves two purposes: firstly, to avoid interference with the cable bracket 3, allowing the upper part of the cable bracket 3 to extend out of the first cover plate 14; secondly, to hold the cable bracket 3 in the square groove, providing support and limiting its position.

[0038] The power cable and control cable both include a main cable and branch cables. Several branch cables are connected in parallel to the main cable. Each branch cable is provided with a terminal plug 12 and a terminal interface 13 at both ends. The terminal plug 12 is inserted into the power interface 5 or control interface 6 of the snow melting board 2. The terminal interface 13 is reserved outside and will be connected to the main cable when the main cable is laid.

[0039] The cable bracket 3 includes a main cable bracket 9 and an outer sheath 10. The main cable bracket 9 is a horizontally arranged T-shaped tee cable tray used to support the main cables of the power cables and control cables. The outer sheath 10 is L-shaped and communicates with the interior of the main cable bracket 9. The vertical part of the outer sheath 10 is connected to the bottom of the main cable bracket 9, and the horizontal part is connected to the power interface 5 or control interface 6 of the snow melting plate 2. It is used to cover the outside of the branch cables of the power cables and control cables for protection.

[0040] The vertical height of the outer protective pipe 10 is greater than the thickness of the waterproof layer of the drainage ditch 1. When the waterproof layer is constructed in the drainage ditch 1, the snow melting board 2, the mounting base 7 and the lower part of the horizontal and vertical parts of the outer protective pipe 10 are all wrapped in the waterproof layer. The wrapping of the waterproof layer plays a further stabilizing role for the outer protective pipe 10, while the upper part of the vertical part of the outer protective pipe 10 and the main line support 9 are exposed to the waterproof layer.

[0041] The main cable bracket 9 has a cover plate 11 on its top. The top of the side wall of the main cable bracket 9 has an upward protrusion, and the bottom of the cover plate 11 has a groove. When laying the main cables of power cables and control cables, the main cables are placed inside the main cable bracket 9, and then the cover plate 11 is installed. The main cable bracket 9 and the cover plate 11 are connected by the protrusion engaging with the groove.

[0042] The above design aims to maximize the pre-assembly of the snow melting board 2 and the drainage ditch 1. Traditionally, snow melting board installation and wiring must be carried out after the waterproofing layer of the drainage ditch is constructed, involving a significant amount of work at height. In this embodiment, however, the snow melting board 2 installation and wiring can be completed during the pre-assembly stage at the factory. The reserved terminal interface 13 extends out of the outer protective tube 10 and is placed inside the main cable bracket 9. During the on-site construction phase, only the main cable needs to be laid and the reserved terminal interface 13 connected to the main cable plug, which is convenient for connection and does not affect the construction of the waterproofing layer of the drainage ditch 1.

[0043] The present invention also provides a construction method, which uses the above-mentioned prefabricated structure of snow melting board and drainage ditch for construction. The specific construction process includes steps S1 to S8, which are described in detail below.

[0044] S1. Process the drainage ditch 1, mounting base 7, snow melting board 2 and cable bracket 3 according to the design drawings.

[0045] S2. Fix several mounting bases 7 in the drainage ditch 1 according to the design position. The connection method is welding or bonding.

[0046] S3. Install the snow melting plate 2 on each mounting base 7 via the limit card 8.

[0047] S4. Install cable bracket 3 inside mounting base 7, and connect a branch cable to the power interface 5 and control interface 6 of each snow melting board. The branch cable is run through the outer protective tube 10. The terminal plug 12 of the branch cable is inserted into the power interface 5 or control interface 6 of the snow melting board. The terminal interface 13 of the branch cable is left outside and placed on the cable bracket 3. After the cable bracket 3 and the branch cable are installed, cover it with the first cover plate 14.

[0048] S5. Transport the integrated drainage ditch 1, mounting base 7, snow melting board 2, cable bracket 3, and branch cable to the construction site and hoist them to the designed position on the roof for installation.

[0049] S6. A waterproof layer is constructed inside the drainage ditch 1. The waterproof layer covers the lower parts of the horizontal and vertical sections of the snow melting board 2, the mounting base 7, and the outer protective pipe 10. The upper part of the vertical section of the outer protective pipe 10 and the main line bracket 9 are exposed outside the waterproof layer.

[0050] S7. Install the main power cable and control cable on the two rows of cable brackets 3, and connect the reserved terminal interface 13 of each branch cable to the pre-made plug on the main cable to realize the parallel connection of each branch cable to the main cable. S8. Install a second cover plate 11 above each cable bracket 3.

[0051] This invention achieves a high degree of integration between the snow melting board 2 and the drainage ditch 1, reducing the amount of high-altitude work during on-site construction, improving construction safety, shortening the construction cycle, and improving construction quality and efficiency.

Any simple modifications, equivalent changes, or alterations made by those skilled in the art using the disclosed technical content shall fall within the protection scope of the present invention.
