Description

Device for reinforcing simple purlines into continuous purlines

Technical Field

The utility model relates to a building structure reforms transform or consolidates the field, and more specifically says, relates to a device that is used for consolidating simple purlin into continuous purlin.

Background

Light steel roofing is still one of the most widely used roofing forms in industrial factory buildings in China at present. Purlines in the light steel roof system have the advantages of high factory mechanization degree, large roof span, light dead weight, less material consumption, environmental protection, lower construction cost, short construction period and the like. At present, purlins are usually simply supported purlins or continuous purlins, and the bending resistance bearing capacity of the purlins of the same type is smaller than that of the continuous purlins. In recent years, due to frequent occurrence of extreme rainy and snowy weather, the load of the roof is far greater than the conventional design load, so that the simple purlines cannot meet the design requirements, or due to the reason of design or construction errors, the continuous purlines are changed into the simple purlines, so that the bearing capacity is greatly reduced, and the design requirements cannot be met.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing a device that is used for consolidating simple purlin into continuous purlin for simple purlin tip possesses the function of undertaking the moment of flexure.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a device for strengthening simple purlin into continuous purlin, holds in the palm including the purlin, and two simple purlins are held in the palm through a plurality of bolts, the upper portion of simple purlin is equipped with the mounting, and the mounting on two adjacent simple purlins passes through the stretch-draw piece and connects, be equipped with adjusting sleeve on the stretch-draw piece.

In the above scheme, the fixing piece is a screw rod, a steel bar or a stud.

In the above scheme, the tension member is a steel bar, a steel strand or a resin member.

In the above scheme, the purlin support is triangular or square.

The utility model discloses the principle as follows:

usually, only one row of common bolts at the end of the simple supporting purline are connected with the purline supporting plate, and the adjacent simple supporting purlines are disconnected at the purline supporting plate. The column of common bolts can only bear shearing force but cannot bear bending moment, namely, the end part of the simply supported purline can only bear shearing force but cannot bear bending moment. The core of the bending resistance is that the upper part of the section of the end part of the purline is pulled and the lower part is pressed, and the moment of couple inside the section can be formed by pulling and pressing. The section of the purline naturally rotates under the action of pressure by exerting pulling force on the upper part of the end part of the simply supported purline in advance, and the lower pressure is naturally formed by the extrusion force of the bolt and the purline. The moment of couple formed in advance in the section can bear the negative moment of the external load.

Implement the utility model discloses a device for inciting somebody to action simple purlin is consolidated into continuous purlin has following beneficial effect:

1. the utility model discloses a mounting is connected purlin and stretch-draw piece and is formed a whole, prestretches the stretch-draw piece and makes purlin upper portion be drawn, and the purlin lower part pressurized simultaneously draws thereby one and presses the couple moment that forms the inside force and couple moment in cross-section to make simple purlin tip possess the function of undertaking the moment of flexure, changes the atress mode then and makes simple purlin optimize to continuous beam stress model by simple stress.

2. The utility model has the advantages of simple and advanced principle, simple construction, improved efficiency, reduced reinforcement period and saved construction cost; the method has the advantages of modular installation and convenient construction; the device has the characteristics of simple and clear structure, safety, stability, high assembly speed and the like, is suitable for efficient cycle operation, and saves construction period and cost.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the device for reinforcing simple purlins into continuous purlins of the utility model comprises a simple purlin 1, a purlin support 2, a fixing member 3 and a tension member 4. Two simple purlines 1 are fixed on a purline support 2 through a plurality of bolts 5, the upper portions of the simple purlines 1 are provided with fixing pieces 3, the fixing pieces 3 on the two adjacent simple purlines 1 are connected through tensioning pieces 4, and the tensioning pieces 4 are provided with adjusting sleeves 6.

The simple purline 1 is not limited in any form, and can be a C-shaped purline or a Z-shaped purline prefabricated by a steel structure, and can also be a square purline or a round purline in a wood structure.

The purlin support 2 is not limited by any material and shape, and can be a triangular plate purlin support matched with a steel structure purlin or other forms, and also can be a square purlin support matched with a wood structure purlin or other forms.

The fixing member 3 is not limited by any type of material and composition, and may be a steel ordinary bolt, a high-strength bolt, a steel bar, or a stud, or may be a high-strength resin material. As long as the tension member 4 is fixed by the fixing member 3, the anchoring function can be exerted. Firstly, drilling holes in the upper parts of the simple purlines 1, and then installing the fixing pieces 3.

The tension member 4 is not limited in material and length in any way, and may be a steel material: steel bars, steel strands, etc., and may also be resin products. As long as a certain tensile strength can be achieved. The tension member 4 is mounted on the fixing member 3, and the tension member 4 is tensioned by rotating the socket 6 of the tension member 4 by a torque wrench, thereby generating a pretension force. The simple supporting purline 1 can rotate and deform under the action of tension, the lower pressure is formed by the extrusion of the bolts and the simple supporting purline 1 naturally, the moment of couple inside the section can be formed by pulling and pressing, and the negative bending moment of external load can be borne, so that the purpose of reinforcing the simple supporting purline into continuous purlines is achieved.

While the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
