Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge steel structure technology, and in particular relates to a fixing component for bridge steel structure processing. Background Technology
[0002] The steel structure of bridges is mostly made of large steel structures. These large steel structures are cut and welded to form special steel frame structures. The steel structures are heavy and not easy to move. Therefore, during the processing, cutting or welding equipment is usually placed directly on the steel beams to reduce the need to move the steel structures.
[0003] In existing technologies, cutting or welding equipment is usually assembled onto the structural beam to be processed using special fixing components. Generally, the fixing components are attached to the structural beam with flanges by snap-fit, and then the cutting or welding equipment is assembled onto the fixing components. However, most current fixing components simply rely on bolt snap-fit to form a force point and fix it to the flange of the structural beam. This method of connection and fixation is not effective enough and can easily affect the processing effect of the cutting or welding equipment. Utility Model Content
[0004] This utility model provides a fixing component for processing bridge steel structures. The utility model is implemented as follows: A fixing component for processing bridge steel structures includes:
[0005] The main beam has a top plate on its top and ear brackets on both sides, forming a first sliding cavity and a second sliding cavity with the main beam and ear brackets; the main beam is provided with inclined top rods for abutting against the web of the structural beam.
[0006] The sliding beams are in two sets, which slide in the first sliding cavity and the second sliding cavity respectively; the front end of the sliding beam is provided with a fixing groove for accommodating the flange of the structural beam to be inserted, and the sliding beam is provided with a locking bolt, which passes through the sliding beam and abuts against the flange inserted into the fixing groove.
[0007] Preferably, the sliding beam is provided with several sets of positioning screw holes arranged in a row, and the lugs and main beam are provided with several sets of screw holes. After the sliding beam is adjusted, the positioning screw holes correspond one-to-one with the screw holes on the lugs and main beam and are fixed by bolts.
[0008] Preferably, the inclined top rod is inclined to the sliding beam, and the end of the inclined top rod away from the main beam is also provided with a pressure plate that contacts and connects with the web of the structural beam.
[0009] Preferably, the top plate extends into main beams at both ends and extends above the first and second sliding cavities, and the sliding beams sliding in the first and second sliding cavities are in contact with the top plate.
[0010] Preferably, the inclined top rod is located in the middle section of the main beam, and the sliding beams are located on both sides of the main beam.
[0011] Preferably, the sliding beam is provided with at least one set of locking screw holes, and the locking bolts extend through the locking screw holes to the fixing groove and abut against the flange of the structural beam.
[0012] Compared with the prior art, the embodiments of this application have the following main advantages:
[0013] The bridge steel structure processing fixing component provided by this utility model uses an inclined top rod as a support structure to hold the structural beam against the web. The sliding beam adopts a sliding structure design, which satisfies the holding requirement of the inclined top rod while also achieving a fixing effect on flanges of different lengths. When the fixed inclined top rod cannot reach the flange, the sliding beam slides to adapt to the flange. This application uses a movable sliding beam to cooperate with the inclined top rod to complete the fixing effect of the structural beam, thereby improving the fixing effect of structural beams with flange structures.

[0023] This utility model embodiment provides a fixing component for processing bridge steel structures, such as... Figures 1-5 As shown, the fixing component for fabricating bridge steel structures is applied to a flanged structural beam 400 and includes:
[0024] The main beam 100 has a top plate 110 on its top and ear brackets 120 on both sides. The main beam 100 and the ear brackets 120 form a first sliding cavity 101 and a second sliding cavity 102. The main beam 100 is provided with inclined top rods 130 for abutting against the web of the structural beam 400. The inclined top rods 130 are inclined to the sliding beam 200. The inclined structure of the inclined top rods 130 can provide oblique support to the main beam 100. The top plate 110 has pre-set blind hole connection holes to serve as a support plane for processing equipment, such as a laser cutting machine guide rail, to ensure that the processing equipment can be connected to the structural beam 400 by relying on the fixed components for bridge steel structure processing.
[0025] The sliding beam 200 is provided in two sets, which slide in the first sliding cavity 101 and the second sliding cavity 102 respectively. The front end of the sliding beam 200 is provided with a fixing groove 201 for accommodating the flange of the structural beam 400. The sliding beam 200 is provided with a locking bolt 300, which passes through the sliding beam 200 and abuts against the flange of the insertion fixing groove 201.
[0026] In this application, the fixing groove 201 at the front end of the sliding beam 200 is basically the same as the fixing method used in the prior art. A semi-enclosed structure is provided to accommodate the flange insertion of the structural beam 400. A locking screw hole communicating with the fixing groove 201 is provided on the sliding beam 200. The locking bolt 300 extends to the fixing groove 201 through the locking screw hole and abuts against the flange of the structural beam 400. The inclined push rod 130 serves as a support structure abutting against the web of the structural beam 400. The sliding beam 200 adopts a sliding structure design, which satisfies the abutment requirement of the inclined push rod 130 while also satisfying the fixing effect on flanges of different lengths. When the obstruction of the fixed inclined push rod 130 prevents the sliding beam 200 from reaching the flange, the sliding beam 200 slides to adapt to the flange. This application uses a movable sliding beam 200 to cooperate with the inclined push rod 130 to complete the fixing effect of the structural beam 400, thereby improving the fixing effect of the structural beam 400 with a flange structure.
[0027] In a preferred embodiment of this invention, the sliding beam 200 is provided with a plurality of sets of arranged positioning screw holes 202, the lug 120 is provided with countersunk screw holes, and the main beam 100 is provided with blind screw holes. The screw holes on the main beam 100 correspond to the screw holes on the lug 120. After the sliding beam 200 is adjusted, the positioning screw holes 202 correspond one-to-one with the screw holes on the lug 120 and the main beam 100 and are fixed by bolts. The fixing groove 201 has a large depth to ensure that the fixing groove 201 can adapt to the flange as much as possible during the spacing adjustment process.
[0028] In practical application, the number of screw holes on the ear bracket 120 and the main beam 100 shall not be less than four sets, and the number of positioning screw holes 202 shall not be less than five sets. The number of positioning screw holes 202 shall be greater than the number of screw holes on the ear bracket 120 and the main beam 100. During the sliding process, the number of bolts used to fix the ear bracket 120 and the main beam 100 shall not be less than three sets. During the movement process, at least three sets of bolts shall be assembled and fixed in the positioning screw holes 202 and the screw holes on the ear bracket 120 and the main beam 100.
[0029] In a preferred embodiment of this invention, the end of the inclined top rod 130 away from the main beam 100 is also provided with a pressure plate that is in contact with and connected to the web of the structural beam 400; the top plate 110, the ear bracket 120 and the inclined top rod 130 are connected by welding to form an integral structure.
[0030] In this embodiment, the top plate 110 extends into main beams 100 at both ends and extends above the first sliding cavity 101 and the second sliding cavity 102. The sliding beam 200, which slides in the first sliding cavity 101 and the second sliding cavity 102, is in contact with the top plate 110. The portion of the top plate 110 extending into the main beams 100 at both ends will exert downward pressure on the sliding beam 200, sharing the structural fixing pressure between the ear bracket 120 and the sliding beam 200.
[0031] In a preferred embodiment of this invention, the inclined top rod 130 is disposed in the middle section of the main beam 100, and the sliding beams 200 are disposed on both sides of the main beam 100. In this embodiment, the inclined top rod 130 is a set, and the sliding beams 200 are disposed on both sides of the inclined top rod 130. The stress points of the inclined top rod 130 and the stress points of the sliding beams 200 are designed to intersect, thereby making the overall support structure of the main beam 100 more stable.
[0032] In a preferred embodiment of this invention, the sliding beam 200 is provided with at least one set of locking screw holes, and the locking bolt 300 extends through the locking screw holes to the fixing groove 201 and abuts against the flange of the structural beam 400.
[0033] When the sliding beam 200 has multiple sets of locking screw holes, the locking bolts 300 are also set to multiple sets accordingly. The more locking bolts 300 there are, the more stress points the sliding beam 200 will have.
