Description

Technical Field

[0001] The invention belongs to a roof drainage structure of a building enclosure system, and in particular relates to a high-strength assembled gutter device. Technical Background

[0002] As the construction industry advocates the application and development of green building materials, concrete gutters are gradually being replaced by steel gutters due to their complex production process and the easy generation of construction waste. Steel gutters are usually installed at the eaves of roofs between large-spacing roof beams, inside parapets, and between roofs of continuous-span buildings to collect roof rainwater and discharge it in an organized manner through downspouts.

[0003] Limited by the existing mechanical processing capabilities and steel plate specifications, it is currently impossible to use mechanical integral pressing to form large-sized steel gutters. The traditional method is to use thin steel plates to fold several meters of trough units, then weld the trough units together and extend them to the length of the roof beam spacing, and then transport them to the project site and hoist them to the roof for installation; considering the strength of bearing rain and snow loads and live loads, this type of combined gutter folded from thin steel plates does not have the installation strength between conventional large-spacing (e.g. 6-9 meters) roof beams. Installation and use require the installation of the end purlins and structural fixed supports of the roof panel at the eaves. The traditional method includes longitudinally setting multiple support rods under the adjacent roof purlins, and the steel gutter is located on the multiple support rods and the vertical edges are folded outward and fixed on the purlins, or a full-length steel purlin is set at the bottom of the gutter as a gutter bracket. However, these traditional methods have the following problems:

[0004] (1) The gutter made of thin steel plate has insufficient rigidity and is easily deformed during transportation and hoisting; (2) The welding between gutters and the welding between the downspout and the gutter are complex and difficult to carry out in a narrow space at high altitude. The installation process is low in efficiency and high in cost, and the appearance after installation is not beautiful; (3) The installation space between purlins on site is small. Purlins near the eaves need to consider both fixing the roof panel and installing the gutter. However, when installing purlins on site, the installation conditions of the gutter are often not considered. The poor straightness of the purlin installation has a great impact on the quality of the gutter installation process; (4) To ensure roof drainage, the gutter cannot be higher than the upper plane of the purlin, so the gutter height is often limited to the height between the roof beam and the upper plane of the purlin. The support height set at the bottom of the purlin affects the gutter height. In order to ensure the gutter capacity, the gutter width needs to be increased, thereby increasing the gutter processing cost and difficulty; (5) Due to the low stiffness of the gutter itself, the roof purlin will bend and deform greatly when the load is large, which will cause the screws fixing the roof panel to loosen; (6) The gutter bracket often collides with the tie rod, affecting the structural force; (7) The longitudinal support structure set at the bottom of the gutter affects the installation of the downpipe.

[0005] In order to reduce the difficulty of construction, improve the efficiency of on-site installation and process quality, and reduce construction costs, researchers have invented many functional gutters and assembled gutters in recent years. Publication No. CN216641184U discloses an assembled gutter structure that can be prefabricated in the factory and easily assembled on site, solving the problems of inaccurate construction dimensions and messy sites. However, the manufacturing process of the assembled gutter is too complicated, and its keel frame requires a lot of welding, resulting in high processing costs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a high-strength assembled gutter device with a simple structure and convenient processing and installation.

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0008] A high-strength assembled gutter device includes a plurality of structural units which are detachably and sealably connected in sequence, each structural unit includes two symmetrically arranged Z-shaped steels pressed and formed by steel plates, a web between the two Z-shaped steels is arranged vertically, and a lower wing plate at the lower end is folded inwardly, and an upper wing plate at the upper end is folded outwardly, a grooved bottom plate is supported on the rolled edge of the lower wing plate between the two Z-shaped steels, vertical edges on both sides of the grooved bottom plate are sealably connected to the web between the two Z-shaped steels, and grooved connecting flanges are fixed at both ends of the two Z-shaped steels for realizing connection between adjacent structural units.

[0009] As a further preference, the cross section of the grooved bottom plate is a U-shaped groove.

[0010] As a further preference, the cross section of the grooved bottom plate is a trapezoidal groove plate to increase strength.

[0011] As a further preference, a plurality of transverse braces and diagonal braces are fixed between the upper openings of the two Z-shaped steels to improve the structural stability and strength.

[0012] As a further preference, the grooved bottom plate is made of stainless steel.

[0013] As a further preference, a drain outlet is provided on the horizontal plate surface of the trough-shaped bottom plate, a drain flange is fixed at the drain outlet, and a drain pipe is detachably fixed through the drain flange.

[0014] As a further preference, an insulating bottom plate is fixed between the lower wing plates at the lower ends of the two Z-shaped steels, and insulating cotton is provided between the insulating bottom plate and the trough bottom plate to avoid condensation at the bottom of the gutter.

[0015] The beneficial effects of the present invention are:

[0016] 1. Compared with the traditional installation method of using conventional folded and welded gutters and combining them with purlins on the construction site, the present invention adopts a high-strength box-type structure composed of steel purlins pressed from steel plates and a grooved bottom plate, which can realize standardized prefabrication in the factory; adjacent structural units are sealed and connected by connecting flanges, so that the longitudinal section does not need to be welded when the gutter is installed on site, the structure is simple, the processing and installation are convenient, the overall appearance is beautiful, and the technical processability and economy of the product are greatly improved.

[0017] 2. The present invention adopts two Z-shaped steels and a trough-shaped bottom plate to form a "box beam" gutter with a strength far higher than that of a single steel purlin. The installation does not require any reinforcing support structure and does not involve any support structure issues that affect the gutter height and other installations. The Z-shaped steel that composes the gutter can be used normally to install color panels, so that the product has the comprehensive functions of drainage and fixing color panels.

[0018] 3. The present invention overcomes the problems of the traditional folded gutters at high places on the roof, such as many welding nodes combined with purlins and supporting structures, great construction difficulty, high cost, and inability to guarantee the quality of the installation process. During construction, it only needs to be hoisted into place and connected by bolts, thus realizing simple and standardized manufacturing in the factory, simple and efficient installation of assembled construction, without the need for a large number of welding combined manufacturing and installation operations. While ensuring the high process quality of the product, it can greatly reduce the production and construction and installation costs.

[0019] 4. The present invention adopts two Z-shaped steels and a trough-shaped bottom plate to form a "box beam" gutter. There is no need to consider the installation quality of the purlin and the impact of space on the installation of the gutter. In order to take into account both drainage and purlin functions, its height can be lower than the conventional purlin height to facilitate installation height adjustment, which is conducive to designing prefabricated standardized products according to conventional purlin heights and avoiding the problem of mismatch between the height of factory-standard manufactured products and conventional purlins.

[0020] 5. The present invention combines standardized factory manufacturing with on-site assembly installation technology. In design, the standardized gutter can be used as a roof positioning node to form a design relationship between the surrounding roof, wall and its combined configuration, providing a new and simple process method for the local node design of building roof gutters, which has always been complex, confusing and difficult.
