Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to a steel structure beam supporting device. Background Art

[0002] In order to ensure the stability of the steel structure beams, a support structure needs to be set up under the beams with longer spans or larger loads. Usually, diagonal bars are welded between the beams and the vertical beams to increase the support strength of the beams. However, this method requires high construction accuracy of the support structure and is difficult to apply to support environments with different angles between the beams and the vertical beams.

[0003] In order to address the above-mentioned problems, there are many solutions in the prior art that use a hinged connection to connect the support structure and the beam body, such as a steel structure support structure disclosed in application number 202310641451.2 and a steel structure beam support device disclosed in application number 202120703877.2. Although this method can be applied to a variety of support environments, its load-bearing components are all hinged shafts with limited load-bearing strength, which can easily affect the service life of the load-bearing structure. In addition, it is difficult to re-support the beam structure that has been deformed and collapsed, and it needs to be manually straightened before it can be supported and fixed. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model adopts a steel structure beam support device to solve the problem that the load-bearing component in the prior art is a hinge shaft and it is difficult to support and fix the deformed beam.

[0005] The technical solution is a steel structure beam supporting device, comprising two fixed blocks symmetrically placed on the left and right, each fixed block having a groove on the lower end face, each groove penetrating an adjacent end face of the two fixed blocks, a load-bearing rod arranged between the two fixed blocks, two ends of the load-bearing rod respectively placed in the two grooves and a horizontal front-to-back cross bar is fixed to the left and right ends of the load-bearing rod located in the grooves, each groove having a transverse oblong hole on the front and back ends, the cross bar is placed in the oblong hole on the corresponding side and can slide left and right along the oblong hole, a blind hole is arranged on the outer end face of each groove, a support block capable of sliding left and right along the blind hole is arranged in the blind hole, the support block always extends out of the blind hole and can be fixed at any position of the blind hole.

[0006] The lower end surface of each fixed block is provided with a vertically placed bolt, the upper end of the bolt passes through the lower end surface of the fixed block to the blind hole, the bolt and the fixed block are connected by threads, and a slider is provided above the bolt in each blind hole, the slider is located at the outer end of the support block and one end surface of the slider adjacent to the support block is an inclined surface, and when the slider moves upward, it can squeeze the support block outward through the inclined surface.

[0007] A handle is fixed on the lower end of the bolt.

[0008] The thickness of the portion where the bolt passes through the fixing block is relatively large, so that the number of internal thread turns on the fixing block is greater than three turns.

[0009] The upper end surface of the fixing block is fixed with two front and rear vertical plates which are symmetrically placed front and back, and each vertical plate is provided with a plurality of through holes which penetrate the front and rear end surfaces.

[0010] The front and rear end surfaces of the load-bearing rod are respectively fitted with the front and rear end surfaces of the sink.

[0011] The two ends of the load-bearing rod are semicircular and the radius is equal to the straight-line distance from the oblong hole circle to the bottom of the sink trough, so that when the load-bearing rod rotates around the cross bar, the end portion disappears and contacts the bottom of the sink trough. The end face of the support block close to the load-bearing rod is an arc surface and is always in contact with the end of the load-bearing rod.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By placing the load-bearing rod in the sink groove on the fixed block and connecting it with the cross bar on the load-bearing rod through the oblong hole, the load-bearing rod has a certain degree of freedom when the fixed block is installed, which can meet the requirements of adapting support for different angles of horizontal beams and vertical beams, while greatly reducing the positioning accuracy of the fixed block during installation and reducing the difficulty of installation;

[0014] 2. By rotating the bolts and sliding, the support block is squeezed against the load-bearing rod, and the load-bearing rod is locked. At the same time, the support block bears the supporting force of the load-bearing rod, which prevents the cross bar from bearing all the pressure and improves the overall service life of the device;

[0015] 3. The slider cooperates with the inclined surface of the support block to decompose the support force of the support block into two parts: the support force of the bottom of the blind hole on the slider and the support force of the bolt on the slider, which greatly reduces the force on the bolt, facilitates the operation of the bolt, and improves the overall support strength and service life of the support device.

[0019] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Depend on Figures 1 to 3The utility model comprises two fixed blocks 1 symmetrically placed on the left and right, each fixed block 1 has a sink groove 2 on the lower end face, each sink groove 2 runs through an adjacent end face of the two fixed blocks 1, a load-bearing rod 3 is arranged between the two fixed blocks 1, two ends of the load-bearing rod 3 are respectively placed in the two sink grooves 2, and the left and right ends of the load-bearing rod 3 are respectively fixed with a horizontal front-to-back placed cross bar 4 on the parts located in the sink grooves 2, each sink groove 2 has a transverse oblong hole 5 on the front and back ends, the cross bar 4 is placed in the oblong hole 5 on the corresponding side and can slide left and right along the oblong hole, each sink groove 2 has a blind hole 6 on the outer end face, a support block 7 that can slide left and right along the blind hole 6 is arranged in the blind hole 6, the support block 7 always extends out of the blind hole 6 and can be fixed at any position of the blind hole 6,

[0021] The lower end face of each of the fixing blocks 1 is provided with a vertically placed bolt 8, the upper end of the bolt 8 penetrates the lower end face of the fixing block 1 to the blind hole 6, the bolt 8 is connected to the fixing block 1 by threads, and a slider 9 is provided above the bolt 8 in each blind hole 6, the slider 9 is located at the outer end of the support block 7 and the end face of the slider 9 adjacent to the support block 7 is an inclined surface, and when the slider 9 moves upward, it can squeeze the support block 7 outward through the inclined surface.

[0022] A handle 10 is fixed to the lower end of the bolt 8 .

[0023] The thickness of the portion of the bolt 8 penetrating the fixing block 1 is relatively large, so that the number of internal thread turns on the fixing block 1 is greater than three.

[0024] The upper end surface of the fixing block 1 is fixed with two front and rear symmetrically placed vertical plates 11 , and each vertical plate 11 is provided with a plurality of through holes 12 penetrating the front and rear end surfaces.

[0025] The front and rear end surfaces of the load-bearing rod 3 are respectively fitted with the front and rear end surfaces of the sink 2.

[0026] The two ends of the load-bearing rod 3 are semicircular and the radius is equal to the straight-line distance from the oblong hole circle to the bottom of the sink 2, so that when the load-bearing rod 3 rotates around the cross bar 4, the end portion disappears and contacts the bottom of the sink 2, and the end face of the support block 7 close to the load-bearing rod 3 is an arc surface and is always in contact with the end of the load-bearing rod 3.

[0027] When the utility model is in use, firstly, the two fixing blocks 1 are fixed on the horizontal beam and the vertical beam of the steel structure respectively, which can be fixed by welding or bolts passing through the through holes 12. Since the two oblong holes 5 are respectively kept vertical and horizontal, one end of the load-bearing rod 3 can move in the vertical direction and the other end can move in the horizontal direction, so that the load-bearing rod 3 has a certain degree of freedom and can be adapted to the horizontal beams and vertical beams with different angles. When the fixing operation of the fixing block 1 is completed, the bolt 8 is rotated manually or by a wrench to move the slider 9 toward one end close to the steel structure. The slider 9 squeezes the support block 7 in the direction of the load-bearing rod 3 through the inclined surface to make it contact with the support block 7, and the load-bearing rod 3 is locked by the two support blocks 7, that is, the support and fixation of the horizontal beam and the vertical beam of the steel structure are completed; for the beam that has collapsed and deformed, the bolt 8 can be continued to be rotated, so that the beam continues to move upward under the thrust of the load-bearing rod 3 until it returns to a normal height and then stops, so that the beam can be reset and supported.

[0028] The utility model places the load-bearing rod 3 in the sink groove 2 on the fixed block 1, and connects it with the cross bar 4 on the load-bearing rod 3 through the oblong hole 5, so that the load-bearing rod 3 has a certain degree of freedom when the fixed block 1 is installed, which can meet the requirements of adapting support for different angles of horizontal beams and vertical beams, and greatly reduce the positioning accuracy of the fixed block 1 when it is installed, and reduce the difficulty of installation;

[0029] After the fixing block 1 is fixed, the slider 9 is moved by rotating the bolt 8 to squeeze the support block 7 against the load-bearing rod 3, thereby completing the locking of the load-bearing rod 3 and at the same time the support force of the load-bearing rod 3 is borne by the support block 3 to avoid the cross bar 4 being subjected to force. The slider 9 cooperates with the inclined surface of the support block 7 so that the supporting force borne by the support block 7 is decomposed into two parts: the supporting force of the bottom of the blind hole 6 on the slider 9 and the supporting force of the bolt 8 on the slider 9. This greatly reduces the force on the bolt, facilitates the bolt operation and improves the overall supporting strength and service life of the support device.
