Background

Steel structure construction, one of the modern building systems, has high strength compared to other constructions, is lighter than other constructions when subjected to the same loads and conditions, is easy to transport and install, and can span a larger span. With the rapid development of steel structure buildings, the steel structure buildings are widely applied to industrial plants and large warehouses, especially large or ultra-long buildings. After the building reaches a certain length specified by a standard, in order to prevent the structure from generating cracks or damage due to the change of the climate and temperature of building components, expansion joints are designed in roof and wall structures. At present, the roof gutter is generally welded into a whole at the joint of expansion joints or is directly connected by rivets at the edge. When the weather temperature changes for a long time, the gutter is easy to crack or deform, and water leakage at the gutter is further caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving above-mentioned technical problem to a certain extent at least. Therefore, the utility model provides a steel construction roofing gutter expansion joint department node, nodal processing are compared in current mode more simply, can effectively solve roofing gutter expansion joint department node when long-time climate temperature change, easily with gutter stretch-breaking or gutter emergence deformation, and then lead to the problem of gutter department percolating water.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a steel construction roofing gutter expansion joint department node, its structural feature is:

at the expansion joint, a pair of the gutters with gutter end sealing plates packaged at the tail ends are oppositely and symmetrically arranged and are respectively and fixedly arranged on the column heads of the steel columns, the top ends of the gutter end sealing plates are reversely bent towards the corresponding gutters to respectively form horizontal flanges, and the upper ends of the horizontal flanges are connected through an expansion joint cover plate;

the expansion joint cover plate is erected on the horizontal flanges on two sides, an upward convex V-shaped protruding structure is formed in the middle of the plate body, the two plate ends form inclined flanges which are bent downwards and outwards at the outer edges of the horizontal flanges on the side where the two plate ends are located, the horizontal flanges of the gutter head plate on each side are fixedly connected with the expansion joint cover plate through a plurality of waterproof self-tapping screws, and the horizontal flanges and the expansion joint cover plate are filled with waterproof glue for plugging.

Further, a plurality of waterproof tapping nails are equidistantly spaced at a distance of 100 mm.

Compared with the prior art, the utility model discloses beneficial effect embodies:

the utility model discloses a connected node structure is succinct, easily preparation, simple to operate, and when weather temperature variation leads to the structure displacement, expansion joint cover can stretch out and draw back through the V-arrangement protrusion structure at middle part, prevents that the gutter from drawing to split or the gutter takes place to warp, can also play the effect of reposition of redundant personnel roofing rainwater, and the installation is simple and direct quick, and the nodal processing mode is simple, and the installation cost is low, and whole outward appearance is effectual, and is economical and feasible.

Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the joint structure at the expansion joint of the gutter on the steel roof of the present embodiment is as follows:

at the expansion joint, a pair of gutters 1 with gutter head sealing plates 2 packaged at the tail ends are oppositely and symmetrically arranged and are respectively and fixedly arranged on the column heads of the steel columns 4, the top ends of the gutter head sealing plates 2 are reversely bent towards the corresponding gutters 1 to respectively form horizontal flanges, and the upper ends of the horizontal flanges are connected through an expansion joint cover plate 3;

expansion joint cover plate 3 sets up on the horizontal turn-ups of both sides, and the plate body middle part forms the bellied V-arrangement protrusion structure that makes progress, and both ends form the slope turn-ups of bending that leans out downwards in the horizontal turn-ups's of place side outer edge department, all link to each other through a plurality of waterproof self-tapping nails 5 are fixed between the horizontal turn-ups of every side gutter head plate 2 and expansion joint cover plate 3, and lead to long packing waterproof glue 6 shutoff between and.

In this embodiment, the plurality of waterproof tapping screws 5 are arranged at equal intervals at an interval of 100 mm.

In specific implementation, reference may be made to the following modes:

1. the method comprises the following steps that a factory manufactures a gutter 1 and a gutter head sealing plate 2 according to the size of the gutter 1, and the gutter 1 and the gutter head sealing plate 2 are welded into a whole in the factory;

2. during on-site construction, a pair of gutters 1 which are manufactured by a factory and are packaged with gutter head plates 2 are opposite and symmetrically arranged on column heads of steel columns 4 at two sides of an expansion joint, and the gutters 1 are reliably connected with the column heads;

3. fixedly mounting an expansion joint cover plate 3 at the upper end of a horizontal flanging of the gutter head sealing plate 2 through a waterproof self-tapping screw 5;

4. waterproof glue 6 is filled between the upper end surface of the horizontal flanging and the expansion joint cover plate 3 in a full length manner for plugging.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
