Description

Steel structure inner gutter

Technical Field

The utility model relates to a steel construction design technical field, especially a gutter structure in steel construction.

Background

At present, light steel factory buildings are rapidly developed in China in recent years due to the advantages of light dead weight, large span, good shock resistance, high construction speed and the like. And many roofs are drained with an inner gutter for aesthetic reasons.

The existing inner gutter is generally U-shaped, and outward curled edges are arranged at the top and hung on flanges of steel purlines on two sides, or a through-long gutter bracket is arranged at the bottom of the gutter. This conventional method has several problems: (1) the requirement on the straightness of the steel purline is high, and a gutter cannot be installed if the steel purline is slightly uneven; (2) when the roof is fully loaded, the turned edge of the gutter is tilted upwards due to stress, so that the roof board is easily tilted and loosened; (3) splashed water drops easily permeate into a room from the plate seam during quick water drainage; (4) gutter brackets tend to collide with the tie bars, affecting structural forces.

It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the actual protection.

Well-known manufacturing methods, control procedures, component dimensions, material compositions, pipe arrangements, etc., have not been described in detail since they are readily understood by those of ordinary skill in the art, in order to avoid obscuring the present invention. Technical solutions between various embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory, contradictory or impossible to realize, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Fig. 1 is a schematic structural view of an embodiment of the present invention in a corresponding midspan position, referring to fig. 1, an embodiment of the present invention provides a steel structure inner gutter, including an inner gutter 100 and a purlin 200, wherein the inner gutter 100 includes a gutter bottom plate 110 located at the lower side and gutter side plates 120 located at the left and right sides. The specific shape and size of the inner gutter 100 and purlin 200 are not intended to be limiting and reference may be made to prior art inner gutters and purlins.

The upper side edge of the gutter side plate 120 is provided with inner rolling plates 121, and a support rod 300 is arranged between the inner rolling plates 121. That is, the brace 300 is located inside the inner gutter 100 and connects the inner roll-up sheets 121 on the left and right sides of the inner gutter 100, so as to reinforce the structure of the inner gutter 100 and prevent the roof panel from being warped and loosened.

A gutter bracket 400 is arranged on the lower side of the inner gutter 100, the gutter bracket 400 comprises a bracket bottom plate 410 positioned on the lower side and bracket side plates 420 positioned on the left side and the right side, and the bracket side plates 420 are positioned on the outer sides of the gutter side plates 120. Thus, the roof purline 200 does not directly bear the pressure transmitted from the inner gutter 100, and the upper flange of the purline 200 is fixed without displacement, thereby realizing the undisturbed effect on the roof panel.

Purlins 200 are mounted on the carriage side plates 420. That is, the purlin 200 is not directly mounted on the inner gutter 100 as in the conventional case, so that the straightness of the purlin 200 is reduced, and the mounting requirements are further reduced.

The design changes the shape and the supporting mode of the traditional inner gutter, and has simple manufacture and good compression stability; the gutter bracket 400 is directly connected to the web of the purline 200, so that the force transmission is more definite; the requirement on the straightness of the purline 200 is not high, and the construction is more convenient; the roof board is not disturbed, and the waterproof performance is more outstanding; saving material and better economy.

Reference will now be made in detail to some embodiments, wherein "an embodiment" is referred to herein as a particular feature, structure, or characteristic that may be included in at least one implementation of the present application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Furthermore, the details representative of one or more embodiments are not necessarily indicative of any particular order, nor are they intended to be limiting.

In example 1, referring to fig. 1 and 3, when the roof position is corresponded, the gutter bracket 400 is a 50 × 3 galvanized sheet strip, the length of the gutter bracket is equal to the width of the gutter bracket +2 × the depth of the gutter bracket, the gutter bracket is connected to the web plates of the steel purlins 5 on two sides of the gutter 1 through self-tapping screws, the distance between the plate brackets 3 is not more than 2M, the specification of the self-tapping screws 4 is not less than M4.8, and the number of the self-tapping screws on each side is not less than 2.

Example 2, referring to fig. 2 and 3, the gutter bracket 400 is offset from the column top at the position corresponding to the column top, that is, the column top (or the beam surface) is directly used as a support, if the height of the steel purlin is insufficient, the lower side of the gutter bracket 400 at the position can be shallow, that is, the gutter is longitudinally made into a variable cross-section shape, and the lower side of the gutter bracket 400 is directly connected with the upper side of the column top (or the beam surface).

In embodiment 3, the inclined position 122 is provided on the upper side of the inner wrap 121. The inclination is consistent with the roof slope, which ensures drainage, and therefore, no additional limitation is made to the specific shape and size of the inclined position 122.

Example 4, a cushion 500 is provided between the inner gutter 100 and the gutter bracket 400. Namely, the cushion layer 500 can be added between the gutter bracket 400 and the inner gutter 100 to adjust the flexibility of the gutter, so that the thickness of the cushion layer 500 can be utilized to adjust the flexibility and the drainage gradient of the inner gutter 100, and the gutter can drain water orderly. The specific cushion layer 500 can be a plastic cushion, which can give consideration to both sealing effect and structural strength.

In embodiment 5, the stay 300 is an angle iron to further improve the structural strength. The spacing between the specific struts 300 is not more than 2 m.

According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
