In view of the above, the utility model provides a connecting structure for a roof net rack and a concrete column, which realizes construction of an upper chord of the roof net rack and completely eliminates the need of chiseling off the existing concrete column.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model relates to a connecting structure of a roof net rack and a concrete column, which comprises
The bolt ball is fixed at the top of the support column;
the first connecting unit comprises a first upper chord connected with the bolt ball and a second upper chord connected with the roof net rack, and the first upper chord and the second upper chord are coaxially arranged;
the second connecting unit is sleeved on the existing concrete frame column, and the first upper chord member and the second upper chord member are fixedly connected together.
According to the utility model, the upper chord members are divided into two parts, and the two upper chord members are respectively fixed on the second connecting units sleeved on the existing concrete frame columns, so that not only can the original concrete members be prevented from being chiseled, but also the space can be fully utilized on the premise of ensuring the safety of the roof net rack.
Preferably, the second connecting unit comprises a first arc-shaped sleeve and a second arc-shaped sleeve which are vertically arranged, and the first arc-shaped sleeve and the second arc-shaped sleeve are welded together; the end part of the first upper chord member is fixed on the first arc-shaped sleeve, and the end part of the second upper chord member is fixed on the second arc-shaped sleeve.
Preferably, the outer surfaces of the first arc-shaped sleeve and the second arc-shaped sleeve are provided with protective layers. During practical construction, the first arc-shaped sleeve and the second arc-shaped sleeve are processed by adopting arc-shaped steel plates, and the color of the protective layer is consistent with that of the roof net rack and can be a zinc protective layer.
Compared with the prior art, the upper chord member of the roof net rack is manufactured into the sectional type processing, the second connecting unit made of the arc-shaped steel plate is arranged on the existing concrete frame column, the upper chord member is welded on the second connecting unit, the upper chord member can be connected, the existing concrete frame column is not required to be chiseled off completely, the structural stability of a connecting position can be ensured, and the outer surface of the second connecting unit can be sprayed with a protective layer consistent with the color of the roof net rack, so that the roof net rack is more attractive and elegant.

Detailed Description
The following describes embodiments of the present utility model in detail with reference to the accompanying drawings, and the embodiments and specific operation procedures are given by the embodiments of the present utility model under the premise of the technical solution of the present utility model, but the scope of protection of the present utility model is not limited to the following embodiments.
In the description of the present utility model, the terms "coupled," "connected," and "connected," as may be used broadly, and may be connected, for example, fixedly, detachably, or integrally, unless otherwise specifically defined and limited; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art in specific cases.
As shown in fig. 1, the connecting structure for a roof truss and a concrete column according to the present utility model includes a bolt ball 1, a first connecting unit and a second connecting unit. Wherein, the bolt ball 1 is fixed on the top of the support column; the first connecting unit comprises a first upper chord member 2 connected with the bolt ball 1 and a second upper chord member 3 connected with the roof net rack, and the first upper chord member 2 and the second upper chord member 3 are coaxially arranged;
the second connecting unit is sleeved on the existing concrete frame column 4 and comprises a first arc-shaped sleeve 5 and a second arc-shaped sleeve 6 which are vertically arranged.
In actual construction, the first arc-shaped sleeve 5 and the second arc-shaped sleeve 6 are processed by adopting arc-shaped steel plates, the colors of the protective layers on the outer surfaces of the first arc-shaped sleeve 5 and the second arc-shaped sleeve 6 are consistent with those of the roof net rack, and the protective layers can be zinc protective layers; the two vertical edges of the first arc-shaped sleeve 5 and the two vertical edges of the second arc-shaped sleeve 6 are welded in a one-to-one correspondence manner to form a cylindrical fixing sleeve, and mounting nodes are provided for the first upper chord 2 and the second upper chord 3.
