Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and in particular mainly to a steel structure with a pre-installed butt joint structure. Background Art

[0002] Steel structure is a structure made of steel materials. The characteristics of steel are high strength, light weight, good overall rigidity and strong resistance to deformation. Therefore, it is particularly suitable for building large-span, super-high and super-heavy buildings. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. The construction is simple and widely used. Therefore, it can be seen that the existing steel structure basically meets people's usage needs.

[0003] When installing existing steel structures, it is necessary to butt the two sets of steel structures so that their threaded holes are aligned and then use bolts to tighten and stabilize them. However, during actual installation, if an offset occurs when the steel frames are directly butt-jointed, the threaded holes will not be aligned, requiring adjustment, which will increase the installation time and reduce the installation efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steel structure with a pre-installed butt joint structure.

[0005] The utility model discloses a steel structure with a pre-installed docking structure, comprising a steel frame, a first connecting plate is fixed at one end of the steel frame, a second connecting plate is fixed at one end of the steel frame away from the first connecting plate, and a pre-fixing component is arranged on the surfaces of the first connecting plate and the second connecting plate, and the pre-fixing component comprises:

[0006] A clamping ring is fixed on the surface of connecting disk one, a circular plate is fixed on the surface of connecting disk two, a sliding groove is opened on the surface of the circular plate, a slide plate is slidably connected to the inner wall of the sliding groove, a limiting plate is fixed on the side of the slide plate close to the center of the circular plate, and the pre-fixed component also includes a linkage, and the limiting plate can limit the clamping ring to prevent displacement when installing the steel frame, which leads to increased installation time.

[0007] Preferably, the connecting member includes a through hole, which is opened inside the skateboard, and a connecting rod passes through the through hole. The skateboard and the connecting rod are each provided with four groups, and the four groups of skateboards and connecting rods are arranged in a circular array with the center of the circular plate as the axis center. Springs are fixed between the four groups of connecting rods, and a surrounding plate is fixed on the side of the circular plate away from the second vertical connecting disk. The inclined surface of the retaining ring abuts against the limit plate, so that the four groups of skateboards can move radially synchronously. When the pull rod is pulled, the skateboards can also move radially synchronously to release the limit.

[0008] Preferably, threaded holes are provided on the surfaces of the first connecting plate and the second connecting plate to facilitate bolt fixing.

[0009] Preferably, the side of the clamping ring away from the second connecting disk is set to be inclined, and the inclined surface abuts against the limiting plate, so that the limiting plate can drive the sliding plate to move away from the side of the center of the circular plate, without causing the first connecting disk and the second connecting disk to fail to fit and abut against each other, thereby facilitating fixed installation.

[0010] Preferably, the slide plate and the connecting rod are both arranged in an arc shape so as not to cause any obstruction during movement.

[0011] Preferably, a pull rod is fixed on the side of the slide away from the limit plate, and the end of the pull rod away from the slide passes through the enclosure plate, and the pull rod is slidably connected to the enclosure plate. When the pull rod is pulled, the slide plate can move radially away from the center of the circular plate, making it convenient for the limit plate to release the limit on the clamping ring.

[0012] Preferably, a handle is provided on the side of the pull rod away from the skateboard for convenience of use.

[0013] Preferably, the clamping ring is arranged in a circular ring shape, and the limiting plate is arranged in an arc shape, so as to facilitate fitting and limiting, or to enable the limiting plate to move when there is a conflict.

[0014] The beneficial effect of the present application is that: through the pre-fixing component that is set up, when the inclined surface of the clamping ring will conflict with the surface of the limiting plate, the limiting plate will drive the sliding plate to move away from the center of the circular plate, and when the surfaces of the connecting disk 1 and the connecting disk 2 are in conflict and fit, the side of the limiting plate close to the circular plate conflicts with the side of the clamping ring away from the inclined surface, so that the limiting plate limits the clamping ring, and the limit is performed by the force of the spring. At this time, the two sets of steel frames can be stabilized, and a preliminary pre-installation can be performed to prevent displacement during installation, which causes the threaded holes to be misaligned and increases the installation time.

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 The steel structure with a pre-installed docking structure in the utility model includes a steel frame 1, a connecting plate 2 is fixed at one end of the steel frame 1, a connecting plate 2 is fixed at the end of the steel frame 1 away from the connecting plate 2, and a pre-fixing component 5 is arranged on the surfaces of the connecting plate 2 and the connecting plate 2 4. The pre-fixing component 5 includes: a clamping ring 50, a circular plate 51, a slide groove 52, a slide plate 53, a limit plate 54, a connecting piece 55, a through hole 550, a connecting rod 551, a spring 552, a surrounding plate 553, and a pull rod 554.

[0022] The clamping ring 50 is fixed on the surface of the connecting disk 1 2, and a circular plate 51 is fixed on the surface of the connecting disk 2 4. A sliding groove 52 is provided on the surface of the circular plate 51, and a slide plate 53 is slidably connected to the inner wall of the sliding groove 52. A limiting plate 54 is fixed to the side of the slide plate 53 close to the center of the circular plate 51. The pre-fixing component 5 also includes a linkage 55, and the linkage 55 includes a through hole 550. The through hole 550 is provided inside the slide plate 53, and a linkage rod 551 is penetrated through the through hole 550. There are four groups of slide plates 53 and linkage rods 551, and the four groups of slide plates 53 and linkage rods 551 are arranged in a circular array with the center of the circular plate 51 as the axis center. Springs 552 are fixed between the four groups of linkage rods 551, and the circular plate 51 is away from the vertical connecting disk 2. A surrounding plate 553 is fixed on one side of 4, and the connecting plate 1 2 of the two groups of steel frames 1 is aligned with the threaded holes 3 in the connecting plate 2 4 in the two groups of steel frames 1. When one group of steel frames 1 is pushed, the inclined surface of the retaining ring 50 will abut against the surface of the limiting plate 54, and the limiting plate 54 will drive the slide plate 53 to move away from the center of the circular plate 51. When the connecting plate 1 2 and the connecting plate 2 4 are in contact and fit with each other, the side of the limiting plate 54 close to the circular plate 51 abuts against the side of the retaining ring 50 away from the inclined surface, so that the limiting plate 54 limits the retaining ring 50, and the limit is performed by the force of the spring 552. At this time, the two groups of steel frames 1 can be stabilized to prevent deviation during installation, resulting in misalignment of the threaded holes 3 and increased installation time.

[0023] The surfaces of the connecting plate 1 2 and the connecting plate 2 4 are both provided with threaded holes 3 for convenient bolt fastening.

[0024] The slide plate 53 and the connecting rod 551 are both arranged in an arc shape, and will not cause any obstruction when moving outward or inward.

[0025] A pull rod 554 is fixed to one side of the slide plate 53 away from the limiting plate 54. One end of the pull rod 554 away from the slide plate 53 passes through the enclosure 553, and the pull rod 554 is slidably connected to the enclosure 553. Pulling the pull rod 554 can release the limiting effect of the limiting plate 54 on the clamping ring 50.

[0026] A handle is provided on the side of the pull rod 554 away from the slide plate 53 to facilitate personnel to exert force.

[0027] The clamping ring 50 is set to be annular, and the limiting plate 54 is set to be arc-shaped, so that the surface of the limiting plate 54 can fit the surface of the clamping ring 50 for easy limiting, or the clamping ring 50 can contact the limiting plate 54 to make the limiting plate 54 move.

[0028] As an application of this embodiment:

[0029] When the steel frame 1 needs to be installed, the connection disks 1 2 of the two groups of steel frames 1 are aligned with the threaded holes 3 in the connection disks 2 4 of the two groups of steel frames 1. At this time, one group of steel frames 1 is pushed so that the connection disk 1 2 is close to the connection disk 2 4. At this time, the inclined surface of the clamping ring 50 will contact the surface of the limiting plate 54. At this time, the limiting plate 54 will drive the slide plate 53 to move away from the center of the circular plate 51. When the connection disk 1 2 and the connection disk 2 4 are in contact and fit, the side of the limiting plate 54 close to the circular plate 51 contacts the side of the clamping ring 50 away from the inclined surface, so that the limiting plate 54 limits the clamping ring 50, and the spring 55 2 is used to limit the position. At this time, the two groups of steel frames 1 can be stabilized to prevent deviation during installation, which will cause the threaded holes 3 to be misaligned and increase the installation time. At this time, personnel can tighten the bolts through the threaded holes 3. When disassembly and maintenance are required, the bolts are removed and the pull rod 554 is pulled on the side away from the center of the circular plate 51. At this time, the pull rod 554 will drive the slide plate 53 to move outward. At this time, through the set slide groove 52 and connecting rod 551, the four groups of slide plates 53 will synchronously move radially away from the side of the center of the circular plate 51, thereby making the limiting plate 54 disengage from the clamping ring 50. At this time, personnel can separate the two groups of steel frames 1.

[0030] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
