Description

Technical Field

[0001] The utility model belongs to the technical field of large-scale light steel roofs, and particularly relates to an eave gutter structure for the roof of a large industrial factory building. Background Technique

[0002] Most large industrial factory building roofs adopt organized drainage, which can prevent rainwater from freely falling and causing scouring of the wall and ground, thus affecting the service life and beauty of the building. Organized drainage divides the roof into several drainage areas, and drains the roof rainwater along a certain drainage slope in an organized manner in a certain direction to the eave gutter or internal gutter, and then discharges it to the apron or open ditch through the rainwater inlet, rainwater bucket and downpipe. The eave gutter is an indispensable part of the organized drainage system of large industrial factory building roofs, and its main function is to collect the rainwater flowing towards the roof eave and guide the rainwater to the downpipe through the rainwater inlet and rainwater bucket.

[0003] At present, the general method for the eave gutter is to adopt an external hanging form, which can be divided into a non-braced eave gutter and a braced eave gutter. For the non-braced eave gutter, one side of the top of the U-shaped gutter mouth is fixed to the lower side of the roof panel through a full-length flat steel strip and bolts, and the other side is supported by a pull condition extending from the upper side of the roof panel out of the gutter. Although the structure of the non-braced eave gutter is simple, its volume is small and the drainage volume is small. When the accumulated rainwater is relatively large, rainwater will overflow from the gutter mouth, and its application range is limited and it is not suitable for use in large industrial factory building roofs. The braced eave gutter places the U-shaped gutter on the support beam extending from the steel column, and one side of the top of the mouth is fixed to the lower side of the roof panel through bolts. Because of the setting of the support, the bearing capacity is large, and a deeper and wider eave gutter can be placed on it, which solves the problem of small drainage volume of the eave gutter to a certain extent. However, for a deeper and wider eave gutter, its own stability and bearing capacity cannot be ignored. Due to the extrusion of water pressure, large lateral deformation is likely to occur at the gutter mouth, and the displacement exceeds the specification limit, so the stability cannot be guaranteed. At the same time, because the drainage volume collected in the gutter is large and the weight is also large, a large negative moment is formed at the mouth of the gutter at the middle support position, which is likely to exceed the bearing capacity limit state of the gutter material, and the bearing capacity cannot meet the requirements. In this case, the conventional method is to set a longitudinal support beam at the bottom of the gutter. However, setting a longitudinal support beam will not only complicate the structure, increase the cost, but also affect the installation of the downpipe.

[0004] Due to its usage requirements, industrial plants with large light steel roofs have large spans, long column spacings, and large floor areas. Correspondingly, the roof water collection area is also large, resulting in a large amount of rainwater collecting at the roof eaves. Moreover, in areas with abundant annual precipitation, higher requirements are put forward for the drainage of the roof eaves. Ordinary external hanging eaves gutters can no longer meet the usage requirements, and deeper and wider eaves gutters must be set to meet the drainage requirements. At the same time, the structure of the eaves gutter should be as simple as possible, and its own stability and bearing capacity requirements should be met. For this reason, a kind of eaves gutter structure applied to the roof eaves of large industrial plants is proposed to solve the above problems.

[0005] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide an eaves gutter structure for the roof of a large industrial plant to solve the problem that ordinary external hanging eaves gutters can no longer meet the usage requirements due to the large drainage volume at the roof eaves of large industrial plants. At the same time, the structure of the eaves gutter is made as simple as possible. On the premise of meeting its own stability and bearing capacity requirements, the roof eaves drainage is made safe, applicable, economical and beautiful.

[0007] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0008] An eaves gutter structure for the roof of a large industrial plant, fixed on a steel column, comprising:

[0009] A gusset plate, fixedly connected to the top side of the steel column;

[0012] A tie bar connecting strip, fixedly connected to the inner side of the gutter groove;

[0013] A limit angle steel, welded to the top of one end of the transverse support cantilever beam and located at the bottom of the gutter groove.

[0014] Preferably, the length of the limit angle steel is the same as the flange width of the transverse support cantilever beam.

[0015] Preferably, the flanges on both sides of the mouth of the gutter groove face the same direction and have a width of 50 mm.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] Refer to the attached Figures 1-5 , a gutter structure for the eaves of a large industrial factory building roof, comprising: a steel column 1, a gusset plate 2 is fixedly connected to the top side of the steel column 1, a transverse support cantilever beam 3 is fixedly connected to one side of the gusset plate 2, a gutter 6 is fixedly connected to the top of the transverse support cantilever beam 3, there are hems 7 on both sides of the opening of the gutter 6, a tie bar connecting strip 5 is fixedly connected inside the gutter 6, and a section of limit angle steel 4 is fixedly connected to the top of one end of the transverse support cantilever beam 3. Among them, the gutter 6 and the hems 7 on both sides of its opening are integrally processed before on-site installation, and the tie bar connecting strip 5 is welded to the specified position inside the gutter 6 by fillet welds at intervals not greater than 2.0 m, so that it can be mass-produced before on-site construction and installation, improving efficiency.

[0035] The limiting angle steel 4 provided at the top end of the transverse support cantilever beam 3 is welded by fillet welds. Its purpose is to prevent the transverse displacement of the bottom of the gutter 6. The length of the angle steel is the same as the flange width of the transverse support cantilever beam 3, and the specification can be the same as that of the tie rod connecting bar 5. One end of the transverse support cantilever beam 3 is perpendicular to the gusset plate 2 and is welded by full penetration groove weld to form a gutter support. The gutter support can also be prefabricated before on-site installation, which can avoid a large amount of on-site welding operations and ensure the quality.

[0036] The gusset plate 2 at one end of the gutter support is closely attached to the flange of the steel column 1 and is connected by fillet welds all around, so that the load of the gutter 6 borne by the transverse support cantilever beam 3 is directly transmitted to the vertical member, the steel column 1.

[0037] In this embodiment, the flanges 7 on both sides of the mouth of the gutter 6 and the inner sides thereof are fixedly connected with tie rod connecting bars 5, which can effectively restrain the transverse deformation of the gutter 6 under the action of water pressure, and has good stability; at the same time, both sides of the gutter 6 can work together to bear force, and the integrity is good. The flange 7 at the mouth of the gutter 6 increases the force-bearing area, has strong bearing capacity, has a large self-span, and does not require a longitudinal support beam to be arranged at the bottom of the gutter 6 when spanning a large column spacing, and can meet the stability and bearing capacity requirements of deeper and wider eaves gutters.

[0038] On the other hand, no longitudinal support beam needs to be arranged at the bottom of the gutter 6, which does not affect the installation of the downpipe, has a simple structure, good economy, and has good applicability. The length of the transverse support cantilever beam 3 can be set according to the width of the gutter, and the operation is convenient. At the same time, the flange 7 on one side of the mouth of the gutter 6 is perfectly connected with the roof panel, which is simple and beautiful.

[0039] The eaves gutter structure for the roof of a large industrial factory building of the present utility model solves the problem that the ordinary external eaves gutter can no longer meet the use requirements due to the large drainage volume at the eaves of the roof of a large industrial factory building. At the same time, the structure of the eaves gutter is made as simple as possible. On the premise of meeting the requirements of its own stability and bearing capacity, the drainage of the roof eaves is made safe, applicable, economical and beautiful, which is very practical and has good market application prospects.
