Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of large-scale light steel roofs, in particular to a gutter structure applied to the roofs of large industrial plants. Background Art
[0002] Gutters are a component of the roof drainage system of steel structure buildings. They are mainly used to collect rainwater and direct it to downpipes to drain the rainwater in time.
[0003] In the design of steel structure, the conventional size of the inner gutter is to place the U-shaped inner gutter stainless steel plate on the steel frame inclined steel beam, and then adjust the height of the purlin support plate of the roof purlin by the slope of the roof to achieve the top connection between the roof panel and the U-shaped inner gutter plate. When it is necessary to set an extra-deep inner gutter, if this method is still used, the height of the purlin support plate needs to be increased. This will make the distance between the lower flange of the purlin and the inclined steel beam too large, making it difficult to effectively ensure the stability of the lower flange of the purlin and the constraint of the purlin on the upper flange of the inclined steel beam, weakening the overall stiffness of the light steel roof composed of the roof purlin and the inclined steel beam. Especially in areas with high wind pressure, this method of raising the purlin support plate is not the best choice for structural design. If the extra-deep inner gutter is sunken without raising the purlin support plate, it will conflict with the position of the rigid tie rod between the steel frame.
[0004] Large industrial plants with light steel roofs have large spans, large column spacing, many spans, and large building areas, which result in large roof drainage. In areas with abundant rainfall in the rainy season, during the design process, ultra-deep internal gutters must be set to meet the drainage requirements. Therefore, a gutter structure applied to the roofs of large industrial plants is proposed to solve the above problems. Summary of the invention
[0005] In order to make up for the above shortcomings, the utility model provides a gutter structure applied to the roofs of large industrial factories, which aims to improve the existing technology for achieving the extraordinary dimensions of such ultra-deep internal gutters, while also serving as a rigid tie rod between rigid frames, and ensuring a reliable connection between purlins and inclined steel beams, and avoiding large deflections during gutter drainage that affect smooth drainage, thereby meeting the drainage requirements of beauty, safety, and economic rationality.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gutter structure applied to the roof of a large industrial factory, comprising a steel column, the top of the steel column is fixedly connected with a gutter groove, the base of the gutter groove is fixedly connected with a longitudinal support beam, one side of the longitudinal support beam is fixedly connected with a node plate, the inside of the steel column is fixedly connected with a stiffening plate, and the bottom of the longitudinal support beam is fixedly connected with a support connecting strip.
[0007] As a further description of the above technical solution:
[0008] The longitudinal supporting beam is specifically made of Q355B I-beam.
[0009] As a further description of the above technical solution:
[0010] At least one column and two rows of bolt holes are arranged on one side of the longitudinal supporting beam.
[0011] As a further description of the above technical solution:
[0012] The longitudinal supporting beam and the node plate are connected by high-strength bolts.
[0013] The utility model has the following beneficial effects:
[0014] 1. In the utility model, the longitudinal support beam has a large bearing capacity, which can meet the bearing capacity requirements of ultra-deep inner gutters, and can also flexibly adjust the position according to the width of the gutter, and has strong operability. In addition, it can also serve as a rigid tie rod between the rigid frames to transmit horizontal forces, and perfectly connect the top of the gutter with the roof panel, which is beautiful, practical and economical.
[0015] 2. In the utility model, the longitudinal support beam can meet the depth setting requirement of the ultra-deep inner gutter without additionally increasing the height of the purlin support plate, effectively ensuring the reliable connection between the roof purlin and the steel frame inclined steel beam, and ensuring the robustness of the overall force of the roof system.
[0016] 3. In the utility model, the supporting connecting strip has a certain rigidity, and even if the longitudinal span of the gutter is large and the transverse width is wide, it can ensure good overall stability. The distance between the longitudinal supporting beams on both sides can be increased to cover the gutter width as much as possible to avoid too much deflection of the gutter stainless steel plate and affect the drainage and drainage efficiency, and the thickness of the gutter stainless steel plate can be reduced to reduce the cost.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1-5 The utility model provides an embodiment: a gutter structure for a roof of a large industrial plant, including a steel column 1, a gutter groove 6 fixedly connected to the top of the steel column 1, a base of the gutter groove 6 fixedly connected to a longitudinal support beam 2, a node plate 3 fixedly connected to one side of the longitudinal support beam 2, and a stiffening plate 4 fixedly connected to the inside of the steel column 1. The stiffening plate 4 is a reinforcement provided at the connection between the node plate and the steel column 1, providing additional support and stability to prevent the web of the steel column 1 from buckling when bearing load. Since the load on the longitudinal support beam 2 is transferred to the steel column 1 to form stress concentration, the stiffening plate 4 is an effective measure to improve the stiffness of the connection node of the steel column 1. The bottom of the longitudinal support beam 2 is fixedly connected with a support connecting strip 5, which is made of equilateral or unequal angle steel and can be set at the lower part of the longitudinal support beams 2 on both sides. The bottom is directly welded to the lower flange of the longitudinal support beam 2, and the support connecting strips 5 are arranged at equal intervals, and the spacing should not be greater than 1500mm. The node plate 3 is a connecting plate extending out to connect the end of the longitudinal supporting beam 2 with the strong axis or weak axis of the steel column 1. It is an important connecting component. By connecting the node plate 3, the load on the longitudinal supporting beam 2 is directly transferred to the vertical component steel column 1.
[0026] Reference Figure 1-4 The longitudinal support beam 2 is made of Q355B I-steel. The longitudinal support beam 2 is preferably symmetrically arranged at the bottom of the gutter groove 6 using the same type of I-steel, and the longitudinal ends are connected at the top of the steel column 1; the type of I-steel is determined by bearing capacity calculation based on the longitudinal column span, gutter width and depth of the factory building. At least one column and two rows of bolt holes are set on one side of the longitudinal support beam 2. High-strength bolts are used to connect the longitudinal support beam 2 and the node plate 3. Such bolts are mainly used to resist shear, which can be calculated by the bolt shear calculation formula (Formula 7.2.2-1 of "Steel Structure Design Standard") Arrange the number of bolts.
[0027] Working principle: By connecting the node plate 3, the load on the longitudinal support beam 2 is directly transferred to the vertical member steel column 1. The stiffening plate 4 improves the stiffness of the connection node of the steel column 1, and the bolts strengthen the connection between the longitudinal support beam 2 and the node plate 3.
