Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure purlin connection, and in particular relates to a connection structure for special-shaped photovoltaic roof purlins. Background Art

[0002] With the continuous progress of society, the application of photovoltaic roofs in the construction field has become more and more extensive. Among them, the fixation of photovoltaic systems has become the most common installation form. In recent years, under the impact of strong typhoons and severe weather conditions, accidents such as wind-blown and overturned photovoltaic roofs have been common.

[0003] In view of the continuous development of society, the application of photovoltaic roofs in the construction field is becoming more and more common, especially the fixing methods of special-shaped photovoltaic systems are showing a trend of diversification. However, in recent years, when encountering strong typhoons and extreme weather conditions, photovoltaic roofs have frequently suffered safety accidents such as wind uplift and overturning, which has become a difficult problem that needs to be solved urgently in the industry. Although photovoltaic roofs have great development potential, their insufficient wind-uplift resistance in actual construction has seriously restricted their further promotion and application.

[0004] In particular, since the purlins of special-shaped photovoltaic roofs generally have a certain angle with each other, such structures are more prone to safety accidents such as wind-blown and overturned due to the influence of strong typhoons and extreme climate. Therefore, we propose a connection structure for special-shaped photovoltaic roof purlins to solve the above problems. Utility Model Content

[0005] The utility model provides a connection structure for special-shaped photovoltaic roof purlins, which can effectively solve the above-mentioned problems.

[0006] The utility model is achieved in this way:

[0007] A connection structure for purlins of special-shaped photovoltaic roofs, the connection structure is used to fix a column and a top transverse rectangular purlin, a first oblique purlin and a second oblique purlin, the first oblique purlin and the second oblique purlin are symmetrically located on both sides of the column, and the angles between the first oblique purlin and the second oblique purlin and the column are both 0°-90°. The connection structure includes a first clamp and a second clamp, the first clamp is located at the top transverse rectangular purlin, the second clamp includes a first part, a second part and a third part, wherein the first part preliminarily locks the first oblique purlin through a first bolt, the second part finally locks the column, the first bolt and the second bolt through a second bolt, the third part preliminarily locks the second bolt through a third bolt, and the first clamp and the second clamp are fixed by a plurality of sets of fixing bolts and nuts.

[0008] As a further improvement, a stiffening rib is provided at the connection between the second part and the first part.

[0009] As a further improvement, a stiffening rib is provided at the connection between the second part and the third part.

[0010] As a further improvement, the length of the second bolt is equal to the sum of the widths of the first oblique purlin, the second oblique purlin and the column plus the thickness of the second hoop.

[0011] As a further improvement, the first clamp and the second clamp are reinforced and connected by six groups of stainless steel bolts.

[0012] The beneficial effects of the utility model are:

[0013] 1. The first clamp cooperates with the second clamp to fix the column to the top transverse rectangular purlin, the first oblique purlin and the second oblique purlin, thereby simplifying the installation of the special-shaped photovoltaic roof purlin.

[0014] 2. By dividing the second hoop into a first part, a second part and a third part, and the first part corresponds to the preliminary fixation of the first oblique purlin, and the third part corresponds to the preliminary fixation of the second oblique purlin, when the first oblique purlin and the second oblique purlin are initially fixed, the angle between the first oblique purlin and the second oblique purlin and the column can be adjusted according to actual construction requirements. After the angle adjustment is completed, the second part is used to finally lock the relative positions of the first oblique purlin and the second oblique purlin and the column, which facilitates the angle adjustment between the first oblique purlin and the second oblique purlin and the column, and can also better target the subsequent angle detection between the three.

[0023] Reference Figure 1-3 As shown, the present embodiment provides a connection structure for special-shaped photovoltaic roof purlins, the connection structure is used to fix the column 9 and the top transverse rectangular purlin 1, the first oblique purlin 3 and the second oblique purlin 2, the first oblique purlin 3 and the second oblique purlin 2 are symmetrically located on both sides of the column 9, and the angles between the first oblique purlin 3 and the second oblique purlin 2 and the column 9 are both 0°-90°, the connection structure includes a first clamp 4 and a second clamp, the first clamp 4 is located at the top transverse rectangular purlin 1, the second clamp includes a first part 7, a second part 6 and a third part 5, wherein the first part 7 preliminarily locks the first oblique purlin 3 through a first bolt, the second part 6 finally locks the column 9, the first bolt and the second bolt 8 through a second bolt 8, the third part 5 preliminarily locks the second bolt 8 through a third bolt, and the first clamp 4 and the second clamp are fixed by a plurality of sets of fixing bolts and nuts.

[0024] The first clamp 4 cooperates with the second clamp to fix the column 9 with the top transverse rectangular purlin 1, the first oblique purlin 3 and the second oblique purlin 2, thereby simplifying the installation of the special-shaped photovoltaic roof purlin. Secondly, the second clamp is divided into a first part 7, a second part 6 and a third part 5, and the first part 7 corresponds to the initial fixation of the first oblique purlin 3, and the third part 5 corresponds to the initial fixation of the second oblique purlin 2. When the first oblique purlin 3 and the second oblique purlin 2 are fixed, the angle between the first oblique purlin 3 and the second oblique purlin 2 and the column 9 can be adjusted according to the actual construction requirements. After the angle adjustment is completed, the second part 6 is used to finally lock the relative positions of the first oblique purlin 3 and the second oblique purlin 2 and the column 9, which facilitates the angle adjustment between the first oblique purlin 3 and the second oblique purlin 2 and the column 9, and can also better detect the angle between the three later.

[0025] Furthermore, a stiffening rib 11 is provided at a connection between the second portion 6 and the first portion 7 , and a stiffening rib 11 is provided at a connection between the second portion 6 and the third portion 5 .

[0026] By providing at least four groups of stiffening ribs 11 at the connection between the second part 6 and the first part 7 and the third part 5, the load transmitted from the upper part to the second clamp can be better strengthened, thereby avoiding stress concentration, and such a design will not damage the original structure.

[0027] Furthermore, the length of the second bolt 8 is equal to the sum of the widths of the first oblique purlin 3, the second oblique purlin 2 and the column 9 plus the thickness of the second hoop.

[0028] Setting the bolt length in this way not only meets the length requirement for installation, but also does not conflict with component installation, thus ensuring the rationality and safety of the structure.

[0029] Furthermore, the first clamp 4 and the second clamp are reinforced and connected by six groups of stainless steel bolts 10.

[0030] Six sets of stainless steel bolts 10 are used to reinforce the connection between the first clamp 4 and the second clamp, so as to better ensure that the top transverse rectangular purlin 1, the first oblique purlin 3, the second oblique purlin 2 and the column 9 can be better fixed together, so that the overall structure can disperse the shear stress well, and the occipital has strong wind resistance and higher reliability.

[0031] The connection structure of the special-shaped photovoltaic roof purlins of the utility model can effectively solve the problems of stability of the photovoltaic roof purlin fixation and weak wind resistance, and achieve the characteristics of firm fixation, strong flexibility, high reliability and strong wind resistance between purlins at different angles.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
