Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a light steel house connection structure, which enables the support block to be fixed in the accommodating groove by the action of gravity, and at the same time, the support plate and the column are in contact with each other to generate friction, so as to avoid the occurrence of the beam and the column. The purpose of loosening.

In order to achieve the above object, the present invention provides the following technical solution: a light steel house connection structure, comprising a support plate, the support plate is fixedly connected with a beam, and the support plate is integrally connected with a support block, the support One end of the block is connected to the support plate, and the other end extends away from the support plate and is inclined in a vertical direction. The column is provided with a fixing hole, and the fixing hole comprises two opposite inclined faces, the two The inclined surface forms a receiving groove for resisting the support block, and the support block is placed in the receiving groove.

By adopting the above technical solution, by the action of gravity, the beam applies vertical downward pressure to the support block, and the support block passes through the fixing hole. Since the two inclined faces are inclined to each other, the receiving groove is generated on both sides of the support block. The pressing force and the pressing force generate frictional force. At the same time, the supporting plate and the column are relatively displaced. The surface of the supporting plate and the fixed plate are pressed to generate a pressing force, and the pressing force generates a friction force, and the friction force and the gravity force jointly act. The support block is fixed to the column and generates a certain relationship between the beam and the column. When vibrating, the support block and the column can be re-fixed by gravity, so as to avoid the occurrence of the loose frame due to the looseness of the support block and the column; without the screw setting, only the support block needs to be buckled into the fixing hole. The installation of the column and the beam can be completed in the middle, and the separation of the column and the beam can be completed by extracting the support block from the fixing hole, so that the installation and disassembly of the worker is relatively simple, and the production efficiency can be greatly improved.

Another object of the present invention is to provide a light steel house connecting structure, which enables the supporting block to be fixed in the receiving groove by the action of gravity, and at the same time, the supporting plate and the fixed plate are in contact with each other to generate friction, so as to avoid loosening of the beam and the column. the goal of.

In order to achieve the above object, the present invention provides the following technical solution: a light steel house connecting structure, comprising a supporting plate and a fixing plate, wherein the supporting plate is fixedly connected with the beam, and the fixing plate is fixedly connected with the column, the The support plate is integrally connected with a support block, and one end of the support block is connected to the support plate, and the other end extends away from the support plate and is inclined in a vertical direction. The fixing plate is provided with a fixing hole, and the fixing hole is fixed. The two inclined faces are formed, and the two inclined faces form a receiving groove for abutting against the support block, and the support block is placed in the receiving groove.

By adopting the above technical solution, by the action of gravity, the beam applies vertical downward pressure to the support block, and the support block passes through the fixing hole. Since the two inclined faces are inclined to each other, the receiving groove is generated on both sides of the support block. The pressing force and the pressing force generate frictional force. At the same time, the supporting plate and the fixed plate are relatively displaced. The surface of the supporting plate and the fixed plate are pressed to generate a pressing force, and the pressing force generates a friction force, and the friction force and the gravity act together. The support block and the column are fixed, and when a certain vibration is generated between the beam and the column, the support block and the fixed plate can be re-fixed by gravity, thereby avoiding the occurrence of the loose frame due to the looseness of the support block and the fixed plate. Without the screw setting, the support column and the beam can be installed only by fastening the support block into the fixing hole, and the support block can be separated from the fixing hole to complete the separation of the column and the beam, so that the worker can install and disassemble. It is relatively simple and can greatly improve production efficiency.

The present invention is further configured such that a side of the support block facing the support plate is provided with a resilient groove, and the longitudinal direction of the elastic groove is disposed in a vertical direction.

By adopting the above technical solution, since the accommodating groove generates a pressing force on both sides of the supporting block, the pressing force causes a pressing force to be generated inside the supporting block, and the supporting block is easily broken from the inside thereof, and the elastic groove can be set. Effectively eliminate the pressing force of the supporting block itself, so that the supporting block has a certain deformation space, and it is not easy to damage the supporting block. When the beam and the column vibrate and move relative to each other, the supporting block generates a certain deformation, so that the supporting block and the receiving block The groove remains in contact, making it difficult for the beam and the column to occur Get rid of.

The invention is further provided that the support block is provided with a guiding slope on one side of the support plate, and the receiving groove is disposed in contact with the guiding slope.

By adopting the above technical solution, the guiding slope can increase the contact area between the supporting block and the receiving groove. When the beam and the column are relatively moved, the pressure caused by the receiving groove to the supporting block can be reduced, and the service life of the supporting block can be further extended. At the same time, the connection stability between the support block and the accommodating groove can be increased, so that the support plate and the accommodating groove are not easily moved relative to each other, and the stand and the cross member can be prevented from being scattered.

The invention is further provided that the support block is disposed in an arc shape away from an end of the support plate.

By adopting the above technical solution, when the support block needs to pass through the fixing hole for connecting the support plate to the receiving groove, the end portion of the arc-shaped support block can guide the connection between the support block and the fixing hole, so that The worker makes it easier to install the support block and the fixing hole, and at the same time, it is not easy to cause injury when the person touches the support block.

The invention is further provided that a reinforcing plate is fixed at the joint of the supporting block and the supporting plate, and the reinforcing plate is placed on a side of the supporting block facing away from the supporting plate.

By adopting the above technical solution, the support plate applies a downward pressure to the fixed plate by the action of gravity. Since the force acts on each other, the inner wall of the receiving groove exerts an upward pressure on the support plate, and the reinforcing plate can effectively prevent the support block from being pressed upward. The action causes the joint between the support block and the support plate to break; when the column and the beam generate vibration, the impulse generated by the vibration is not easy to damage the support block, so that the reinforcing plate has a good protection effect on the support block. Can increase the load bearing capacity of the support block.

By adopting the above technical solution, the positioning rod is passed through the first positioning hole and the second positioning hole. When the relative displacement between the column and the beam is caused by the vibration, the inner walls of the first positioning hole and the second positioning hole are respectively aligned with the positioning rod. When the conflict occurs, the relative displacement between the support plate and the fixed plate can be avoided, thereby effectively preventing the column and the beam from loosening, increasing the connection stability between the column and the beam, and effectively increasing the bearing capacity of the support block.

The present invention is further configured such that one end of the positioning rod is provided with a guiding arc surface, and the guiding arc surface is disposed in contact with the inner wall of the first positioning hole and the inner wall of the second positioning hole.

By adopting the above technical solution, after the support plate and the fixed plate are connected through the support block, the arrangement of the guiding curved surface can facilitate the positioning rod to pass through the first positioning rod and the second positioning rod, thereby improving the simplicity of installation.

The invention is further provided that the fixing plate is provided with a concave surface, and the vertical column is placed in the concave portion and is welded to the fixing plate.

By adopting the above technical solution, the concave setting increases the contact area between the fixed plate and the column, so that the connection between the fixed plate and the column is stronger.

The invention also provides a method for installing a light steel house connecting structure, so as to make the beam and the column difficult to loosen, including the following steps:

Step 1: placing the support plate above the fixed plate, and then speaking, the support plate is moved obliquely downward, and the support block is disposed in the fixing hole from top to bottom;

Step 2: applying a downward pressure to the support plate to generate a frictional force between the support block and the inclined surface, and causing the support block to slightly deform inward while dislocating the axis of the first positioning hole and the second positioning hole;

Step 3: The positioning rod is sequentially passed through the second positioning hole and the first positioning hole, so that the second positioning hole is coaxial with the first positioning hole.

By adopting the above technical solution, a downward pressure is applied to the support plate, so that a certain frictional force is generated between the support block and the fixing hole, and the support plate and the fixed plate are not easily separated, and then the positioning rod is inserted through the first positioning hole and the second. In the positioning hole, the pressure generated between the supporting block and the fixing hole is further increased, so that the connection between the supporting plate and the fixing plate is more stable, so that the beam and the column are not easily loosened.

In summary, the present invention has the following beneficial effects:

After the support block passes through the fixing hole, the surface of the support plate is in contact with the surface of the fixed plate or the column by the action of gravity. At this time, since the first positioning hole and the second positioning hole are not coaxially disposed, that is, the first positioning hole The axis of the second positioning hole is arranged up and down. When the positioning rod passes through the first positioning hole and the second positioning hole, a pressing force can be generated on the inner walls of the first positioning hole and the second positioning hole to make the support plate There is a tendency to move relative to the fixed plate, and the support plate and the fixed plate are pre-tightened, so that the connection between the support plate and the fixed plate is tighter, the connection stability between the support plate and the fixed plate is improved, and the column and the column are further reduced. The beam is loose.
