Description

Technical Field

[0001] The utility model relates to the technical field of roof supports, and more specifically, to a device for preventing roof supports from sagging. Background Art

[0002] As early as the early 1960s, my country conducted research and experiments on portal frames, mainly on the plastic design of frames, and adopted them in the pilot process. In the light steel roof structure system, the roof support is an important force transmission structure system, which is related to the safety of the entire roof system. Its supporting components usually use round steel sections, which are light in weight and have good force transmission; however, when the roof is used with a large load, or there are heavy-duty cranes, suspension cranes, etc., or in the concrete steel roof structure system, the roof support usually needs to use angle steel supports to meet the force transmission requirements. However, due to its heavy weight, angle steel will be obviously bent and deflected during use as roof support, which will affect the force transmission effect and structural safety, as well as the appearance of use. Therefore, it is necessary to improve and optimize it, so as to effectively solve the problem of deflection of roof angle steel supports during use, so as to ensure that the roof support system can effectively play a force transmission role during the lateral force transmission process, truly form a lateral support effect on the roof steel beam, and effectively support and transmit force to the entire structural system, thereby ensuring the safety of the structural system to the greatest extent, limiting the lateral displacement of the entire building system, and effectively alleviating and correcting some inevitable deformations caused by angle steel supports during transportation and installation. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a device for preventing roof support from deflecting, which has the advantages of preventing deflection and low cost.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for preventing roof support from deflecting, comprising a connecting angle steel, the surface of which is fixedly provided with fasteners, there are four groups of fasteners, all of which are arranged on the two side limbs of the connecting angle steel, the back of which is fixedly provided with a roof purlin, the connecting angle steel and the roof purlin are fixedly connected by two groups of fasteners, a U-shaped piece is movably installed at the bottom of the connecting angle steel, the U-shaped piece and the connecting angle steel are threadedly sleeved by fasteners, a supporting angle steel is fixedly provided inside the U-shaped piece, and the U-shaped piece and the supporting angle steel are in contact with each other and support the supporting angle steel.

[0005] As a preferred technical solution of the utility model, the fastener is composed of two nuts, and the nuts are movably installed on the two side limb surfaces of the connecting angle steel.

[0006] As a preferred technical solution of the utility model, the U-shaped piece is formed by bending galvanized round steel with threads at both ends, with a diameter of 18 mm and a strength of not less than 235 MPa.

[0007] As a preferred technical solution of the utility model, the connecting angle steel is L-shaped, the rear of which fits with the roof purlin, and a U-shaped piece is fixedly provided at the bottom, and the U-shaped piece and the connecting angle steel are threadedly connected by fasteners.

[0009] As a preferred technical solution of the utility model, the two sets of threads of the U-shaped piece are both sleeved with the threads of the nut, which are responsible for fixing the U-shaped piece, and the U-shaped piece can be adjusted through the nut.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1.

[0019] Before starting to install the device, it is necessary to pre-drill holes in the connecting angle steel 2 and the roof purlin 6 at the corresponding installation positions, and drill holes in the connecting angle steel 2 at the corresponding connection positions of the connecting angle steel 2 and the U-shaped member 5. Then the staff observes the roof and selects the roof purlin 6 with the shortest horizontal distance from the intersection of the roof support angle steel 4 for installation, and the installation position of the device on the roof purlin 6 should be as close to the midpoint of the roof support angle steel 4 as possible. After the staff has selected a suitable position, the staff first fixes the connection between the connecting angle steel 2 and the roof purlin 6 with the fastener 1. At this time, the screw rod passes through the punching position, and the connection between the connecting angle steel 2 and the roof purlin 6 is tightened through the cooperation between the screw rod and the two sets of nuts 3. Then the staff fastens the U-shaped member 5 is placed at the bottom of the connecting angle steel 2, and the thread on its top passes through the pre-punched position, and then the nut 3 is rotated to make the threaded sleeve between the nut 3 and the U-shaped member 5, so as to fix the U-shaped member 5. At this time, the staff can adjust the height of the U-shaped member 5 through the nut 3 to adapt to different on-site conditions and ensure that the U-shaped member 5 can support the supporting angle steel 4. When the installation is completed, the U-shaped member 5 connects the web of the roof supporting angle steel 4 and the roof purlin 6, and uses the roof purlin 6 to bear the dead weight of the roof supporting angle steel 4. Since the sectional inertia moment of the roof purlin 6 is larger than that of the roof supporting angle steel 4, the deflection of the roof supporting angle steel 4 can be reduced, thereby ensuring the effectiveness of the roof supporting angle steel 4 in the force transmission process and forming a true lateral support system.

[0020] The roof support angle steel 4 and the roof purlin 6 are connected to each other through the U-shaped member 5, so that the roof purlin 6 bears the deadweight supported by the support angle steel 4 to reduce its downward deflection. Compared with the traditional device, the device can connect the U-shaped member 5 so that the support angle steel 4 only needs to bear the lateral force, thereby improving its effectiveness in the force transmission process and increasing the lateral stiffness of the roof support system.

[0021] Since the U-shaped member 5 is formed by bending galvanized round steel, the processing procedure is simple, the cost is low, and the economy is good. It can also be prefabricated in a factory and installed and used on site. Compared with traditional devices, the installation process of the device is not only relatively simple, but the height of the U-shaped member can also be raised and lowered by adjusting the nut, thereby enhancing the universality for different on-site conditions.

[0022] The fastener 1 is composed of two nuts 3 , and the nuts 3 are movably installed on the two side limb surfaces of the connecting angle steel 2 .

[0023] Responsible for fixing the connecting angle steel 2 to the roof purlin 6 and the U-shaped member 5.

[0024] The U-shaped member 5 is formed by bending galvanized round steel with threads at both ends, with a diameter of 18 mm and a strength of not less than 235 MPa.

[0025] The connecting angle steel 2 is L-shaped, and its rear is in contact with the roof purlin 6 . A U-shaped piece 5 is fixedly provided at its bottom, and the U-shaped piece 5 and the connecting angle steel 2 are threadedly connected by a fastener 1 .

[0026] Among them, a screw rod is movably installed above the connecting angle steel 2, and there are two groups of screw rods, all of which are threadedly connected with the nut 3, and one end of the screw rod passes through the back of the roof purlin 6, which is responsible for fixing the connection between the angle steel 2 and the roof purlin 6.

[0027] The two sets of threads of the U-shaped member 5 are both threadedly sleeved with the nut 3 , which are responsible for fixing the U-shaped member 5 , and the U-shaped member 5 can be adjusted through the nut 3 .

[0028] The working principle and use process of this utility model:

[0029] Before starting to install the device, it is necessary to pre-drill holes in the connecting angle steel 2 and the roof purlin 6 at the corresponding installation positions, and drill holes in the connecting angle steel 2 at the corresponding connection positions of the connecting angle steel 2 and the U-shaped member 5. Then the staff observes the roof and selects the roof purlin 6 with the shortest horizontal distance from the intersection of the roof support angle steel 4 for installation, and the installation position of the device on the roof purlin 6 should be as close to the midpoint of the roof support angle steel 4 as possible. After the staff has selected a suitable position, the staff first fixes the connection between the connecting angle steel 2 and the roof purlin 6 with the fastener 1. At this time, the screw rod passes through the punching position, and the connection between the connecting angle steel 2 and the roof purlin 6 is tightened through the cooperation between the screw rod and the two sets of nuts 3. Then the staff fastens the U-shaped member 5 is placed at the bottom of the connecting angle steel 2, and the thread on its top passes through the pre-punched position, and then the nut 3 is rotated to make the threaded sleeve between the nut 3 and the U-shaped member 5, so as to fix the U-shaped member 5.

When the installation is completed, the U-shaped member 5 connects the web of the roof supporting angle steel 4 and the roof purlin 6, and uses the roof purlin 6 to bear the dead weight of the roof supporting angle steel 4. Since the sectional inertia moment of the roof purlin 6 is larger than that of the roof supporting angle steel 4, the deflection of the roof supporting angle steel 4 can be reduced, thereby ensuring the effectiveness of the roof supporting angle steel 4 in the force transmission process and forming a true lateral support system.
