Description

Technical Field

[0001] The utility model belongs to a roof drainage structure of a building enclosure system, in particular to a high-strength assembled gutter device. Background Art

[0002] With the advocacy of green building materials, concrete gutters are gradually being replaced by steel gutters due to their complex production process and the high generation of construction waste. Steel gutters are typically installed at roof eaves between widely spaced roof beams, within parapets, and between roofs of consecutive spans. They collect rainwater from the roof and drain it in an organized manner through downspouts.

[0003] Limited by existing machining capabilities and steel plate specifications, it is currently impossible to use mechanical integral pressing to form larger steel gutters. The traditional method is to use thin steel plates to fold several meters long 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, snow loads and live loads, this type of gutter folded from thin steel plates does not have the installation strength between roof beams with conventional large spacing (such as 6-9 meters). Installation and use require the installation of the end purlins of the roof panel at the eaves and structural fixed support. Traditional methods include setting multiple support rods longitudinally under adjacent roof purlins, and the steel gutter is located on the multiple support rods with the vertical edges folded outward and fixed on the purlins, or setting a full-length steel purlin at the bottom of the gutter as a gutter bracket. However, these traditional methods have the following problems:

[0004] (1) Gutters made of thin steel plates have insufficient rigidity and are prone to deformation during transportation and hoisting. (2) The welding between gutters and the welding between downspouts and gutters are complex and difficult to install in a small, high-altitude space. The installation process is inefficient and expensive, and the appearance after installation is not beautiful. (3) The installation space between purlins on site is small. Purlins near the eaves require consideration of both fixing the roof panels and installing the gutters. However, when installing purlins on site, the installation conditions of the gutters 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, which increases 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 stress; (7) The longitudinal support structure set at the bottom of the gutter affects the installation of the downspout.

[0005] To reduce construction difficulty, improve on-site installation efficiency and process quality, and lower construction costs, researchers have recently developed a variety of functional and prefabricated gutters. Publication No. CN216641184U discloses a prefabricated gutter structure that can be prefabricated in a factory and easily assembled on-site, solving the problems of imprecise construction dimensions and cluttered construction sites. However, the manufacturing process for this prefabricated gutter is complex, and the keel requires extensive welding, resulting in high processing costs. Utility Model Content

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

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A high-strength assembled gutter device includes multiple structural units that are detachably and sealed connected in sequence. Each structural unit includes two symmetrically arranged Z-shaped steels pressed and formed by steel plates. The web between the two Z-shaped steels is arranged vertically, and the lower wing plate at the lower end is folded inward, and the upper wing plate at the upper end is folded outward. A grooved bottom plate is supported on the rolled edge of the lower wing plate between the two Z-shaped steels. The vertical edges on both sides of the grooved bottom plate are sealed with the web between the two Z-shaped steels. Grooved connecting flanges are fixed at both ends of the two Z-shaped steels to achieve connection between adjacent structural units.

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

[0010] As a further preference, the cross section of the trough bottom plate is a trapezoidal trough 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 trough-shaped 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 insulation bottom plate is fixed between the lower wing plates at the lower ends of the two Z-shaped steels, and insulation cotton is provided between the insulation bottom plate and the trough bottom plate to avoid condensation at the bottom of the gutter.

[0015] The beneficial effects of the utility model are:

[0016] 1. Compared with the traditional installation method of conventional folded and welded gutters and combined with purlins on the construction site, the utility model adopts a high-strength box-type structure composed of steel purlins pressed from steel plates and a grooved bottom plate, which can realize factory standardized prefabrication; 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 utility model 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 installation issues. The Z-shaped steel that makes up the gutter can be used normally to install color plates, so that the product has the comprehensive functions of drainage and fixing color plates.

[0018] 3. The utility model overcomes the problems of traditional folded gutters that have many welding nodes when combined with purlins and supporting structures at high places on the roof, which makes construction difficult, costly, and unable to guarantee the quality of 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 and simple and efficient installation of assembled construction. There is no need to use a large number of welding combined manufacturing and installation operations. While ensuring high process quality of the product, it can greatly reduce the production and construction and installation costs.

[0019] 4. The utility model adopts two Z-shaped steels and a trough-shaped bottom plate to form a "box beam" gutter. There is no need to consider the impact of purlin installation quality and space on gutter installation. 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 height, avoiding the problem of mismatch between the height of factory-standard manufactured products and conventional purlins.

[0020] 5. This utility model 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 their 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.
