Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated building construction equipment, specifically to an integral hoisting gutter. Background Technology

[0002] Stainless steel gutters are widely used as drainage structures in current building metal roofing projects, but their installation efficiency is generally low, especially in linear buildings such as platform canopies. Traditional construction methods require cutting the gutters into multiple sections and splicing them on-site. This process necessitates positioning, adjusting the joints, and welding each section for fixation. Segmented installation not only increases the risks of working at heights but is also difficult to implement in confined spaces or in inclement weather, significantly delaying the overall construction period. Furthermore, on-site welding joints are prone to misalignment due to construction errors, leading to frequent uneven welds and creating potential leaks later on.

[0003] Existing segmented gutter installation technology suffers from three main drawbacks: First, the welding quality at the segment joints is highly susceptible to human error, and uneven welds can easily lead to poor drainage or leaks. On-site repairs require additional protective measures, significantly increasing construction costs. Second, segmented hoisting and adjustment are time-consuming, failing to meet the schedule requirements of projects with tight deadlines. Third, the overall appearance quality after assembling multiple gutter segments is difficult to control uniformly; areas with dense welds are prone to corrosion, and repeated welding results in a high material wastage rate. These problems hinder the improvement of engineering efficiency and reliability in metal roofing systems. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes an integral hoisting gutter, which can overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] A type of integrally hoisted gutter;

[0007] The integrated gutter includes modular gutter units and steel lugs fixed to the building structure keel. The ends of the modular gutter units are provided with steel lugs integrally formed therewith. The steel lugs and steel lugs are detachably connected by bolts. The modular gutter unit is a whole component pre-assembled in the factory or on the construction site by a stainless steel gutter body and at least two symmetrically arranged steel lugs.

[0008] Furthermore, the steel ear plate includes a vertically arranged connecting plate and a horizontally extending fixed wing plate. The connecting plate has connecting holes that match the bolts, and the fixed wing plate is welded and fixed to the building structure keel.

[0009] Furthermore, the steel lug is a T-shaped bent steel plate, with its horizontal straight edge fixedly connected to the side wall of the gutter body, and positioning holes matching the bolts are opened on the horizontal edge.

[0010] Furthermore, the inner wall of the stainless steel gutter body of the modular gutter unit is coated with an anti-corrosion coating, which is a hot-dip galvanized aluminum composite coating with a thickness of 20-40μm, and forms a continuous, leak-free covering layer in the bolt connection area between the steel lug plate and the edge of the steel lug.

[0011] Furthermore, the positioning hole on the steel lug is an oblong hole, the length of which is perpendicular to the length of the gutter.

[0012] Furthermore, the mating ends of adjacent modular gutter units are provided with sealing strips, which are embedded in the joint grooves of the gutter body.

[0013] Furthermore, the bolt is a stainless steel internal hexagon bolt, and its threaded end is fitted with an anti-loosening washer.

[0014] Furthermore, the modular gutter unit is 8-12 meters long, and at least two sets of steel lugs are symmetrically arranged at both ends of the unit.

[0032] In practical use, the implementation of the integrated hoisting gutter system according to this utility model includes the following steps:

[0033] Factory modular prefabrication: The stainless steel gutter body is welded and fixed to the steel lugs to form modular gutter units of a predetermined length. An anti-corrosion coating is evenly applied to the inner wall of the gutter using automated spraying equipment, controlling the coating thickness within the range specified in national standard GB / T30790, and accelerating the coating hardening using constant temperature curing equipment.

[0034] On-site positioning and installation: Measure and position the welding points of the steel ear plates on the building structure keel, and fully weld and fix them to the fixing wing plates. Hoist the modular gutter unit to the installation position, align the positioning holes on the steel ear side with the connection holes of the steel ear plate, insert the stainless steel bolts, and tighten them in stages using a torque wrench until the bolt anti-loosening washers are completely flattened.

[0035] Unit mating seal: An elastic deformation gap is reserved at the mating end of adjacent gutter units. After the closed-cell foam sealing strip is installed, it is locked with connectors.
