A steel structure support structure

Abstract

This invention relates to a steel structure support structure. A support base is installed within a pre-embedded concrete foundation and engages with a receiving groove on the foundation. A support sleeve and the support base form a vertical insertion fit. A column is installed within the support sleeve and provides support to the outer surface of the column. A connector is located at the upper end of the column, and one end of a crossbeam is in a horizontal sliding fit with the connector. A drive mechanism drives the support sleeve to move vertically along the column, and simultaneously connects the connector to the upper end of the column for fixation. The crossbeam in this structure can slide on the connector, providing reliable vertical support while allowing the crossbeam to undergo horizontal expansion and contraction. This effectively eliminates stress concentration at the connection between the crossbeam and the column, ensuring reliable support of the column for the upper crossbeam and avoiding slippage caused by the fixed connection between the upper end of the column and one end of the crossbeam, thus ensuring the stability of the column's support for the crossbeam.

Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and specifically to a steel structure support structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings. Therefore, steel structures are widely used in building structures abroad, and in recent years, their application in multi-story and high-rise civil buildings in China has also become increasingly widespread. In steel structures, the steel columns are the node columns that connect the steel beams in various directions. Because some steel beams are quite long, if certain sections of the beams lack support, they are prone to collapse under vibration. Therefore, supporting columns are generally used to support the middle of the steel beams. Since these columns do not connect the steel beams but only provide support, the seismic resistance requirements for these supporting columns are generally lower in current technology.

[0003] With the development of modern industrial technology, houses can be manufactured in batches, much like machine production. Structural components produced using this method are called prefabricated building components, and prefabricated steel structure columns are one type. However, existing prefabricated steel structure columns face the following problems during actual installation:

[0004] (1) After the bottom of the column is installed on the ground, the column and the concrete foundation on the ground are often connected by screws. The screw connection is prone to corrosion and the metal parts such as screws need to be rust-proofed regularly. The actual maintenance of steel structure buildings is quite difficult.

[0005] (2) A crossbeam is installed at the top of the column. The crossbeam and the column are rigidly connected. When there is a disaster such as foundation subsidence or earthquake, the column and the concrete foundation may be misaligned or torn. The connection position between the column and the crossbeam may also be misaligned, which will have a significant impact on the support stability of the entire prefabricated building. Summary of the Invention

[0006] The purpose of this invention is to provide a steel structure support structure that can ensure the stability of the connection between the column and the base, and also ensure the reliable support of the column for the upper beam, avoiding the slippage problem caused by the fixed connection between the upper end of the column and one end of the beam, thus ensuring the stability of the column's support for the beam.

[0007] The specific technical solution adopted by this invention is as follows:

[0009] The support sleeve is vertically inserted into the support base.

[0010] A column is installed inside the support sleeve, and the support sleeve provides support for the outer surface of the column;

[0011] A connector is located at the upper end of the column, and one end of the crossbeam is in a horizontal sliding fit with the connector.

[0012] The drive mechanism drives the support sleeve to move vertically along the column, and the connecting body is fixed to the upper end of the column.

[0013] The present invention also has the following features:

[0014] In a preferred embodiment of the invention, a clamping unit is provided at the upper end of the support sleeve, and the clamping unit is used to drive the support sleeve to clamp the outer surface of the column.

[0015] In a preferred embodiment of the invention, a limiting unit is provided between the support base and the support sleeve. The driving mechanism drives the support sleeve to move vertically along the support base. When the support sleeve moves vertically to the lowest point, the driving mechanism drives the support sleeve to rotate, and the limiting unit fixes the position of the support sleeve.

[0016] In a preferred embodiment of the invention, the support base is generally cylindrical in shape, and the support base is provided with a cylindrical cavity. The support sleeve is inserted into the cylindrical cavity. The limiting unit includes a limiting protrusion provided on the outer wall of the support sleeve. The support base is provided with a vertical slide rail and a horizontal limiting slide rail. The lower end of the vertical slide rail is connected to one end of the horizontal limiting slide rail. The vertical slide rail and the horizontal limiting slide rail allow the limiting protrusion to pass through. The driving mechanism drives the support sleeve to move vertically and rotate, and also drives the limiting protrusion to move along the vertical slide rail and rotate into the horizontal limiting slide rail.

[0017] In a preferred embodiment of the invention, multiple sets of limiting protrusions are arranged along the circumferential direction of the outer wall of the support sleeve, and the limiting protrusions are spaced apart along the length direction of the outer wall of the support sleeve. The position and length of the vertical slide rail correspond to the position of the limiting protrusions, and the position and length of the horizontal limiting slide rail correspond to the position and rotation angle of the limiting protrusions. The upper side of the horizontal limiting slide rail is provided with a first limiting surface and a second limiting surface. The first limiting surface and the second limiting surface are arranged vertically, and there is a rounded transition between the first limiting surface and the second limiting surface. The upper plate surface of the limiting protrusion abuts against the first limiting surface or the second limiting surface.

[0018] In a preferred embodiment of the invention, the outer wall of the support sleeve has a through opening along its length. Multiple sets of these through openings are arranged along the circumferential direction of the support sleeve, dividing it into multiple sets of tube flaps. The limiting protrusions are respectively installed on their respective tube flaps. The clamping unit includes a clamping support ring disposed on the outer ring of the upper end of the support sleeve. A sliding rod is disposed at the upper end of each tube flap. The sliding rod is horizontal and arranged along the radial direction of the support sleeve, and the sliding rod and the clamping support ring form a sliding fit. The sliding rod is fitted with a clamping spring at its extended end. The two ends of the clamping spring abut against the sliding rod and the support sleeve, respectively. A clamping drive block extends horizontally from the upper end of the support sleeve. The outer surface of the clamping drive block is provided with a first vertical surface and a second vertical surface. The first vertical surface and the second vertical surface are connected by an inclined plane. The drive mechanism includes a drive cylinder fitted outside the support base. The drive cylinder is vertical and its inner wall abuts against the first vertical surface or the second vertical surface, and it drives the tube valve body to move in the radial direction.

[0019] In a preferred embodiment of the invention, the receiving groove of the pre-embedded concrete foundation is generally constricted, and the edge of the receiving groove is provided with receiving openings. Multiple sets of receiving openings are arranged at intervals along the circumferential direction of the edge of the receiving groove. The lower end of the drive cylinder is provided with a snap-fit ​​flange, which is arranged corresponding to the receiving opening. The drive cylinder drives the support sleeve to move vertically and rotate, so that the snap-fit ​​flange passes through the receiving opening and abuts against the edge of the receiving groove opening.

[0020] In a preferred embodiment of the invention, a mounting base is provided at the upper end of the column, and a snap-fit ​​groove is provided on the mounting base. The snap-fit ​​groove has a rectangular outline and multiple sets of snap-fit ​​grooves are spaced apart along the circumferential direction of the mounting base. The connector is installed in the snap-fit ​​groove.

[0021] In a preferred embodiment of the invention, the connector is generally in the form of a right-angled folded plate. One end of the connector is vertically engaged in the engaging groove, and the vertical side of the connector is in contact with the groove wall. The other end of the connector is horizontal and has an engaging end. One end of the crossbeam is inserted into the engaging end, and the crossbeam and the engaging end form a horizontal sliding fit. A support roller extends from the mounting base, and the horizontal side of the other end of the connector abuts against the support roller. Multiple sets of support rollers are horizontally arranged along the extending direction of the horizontal side of the other end of the connector.

[0022] In a preferred embodiment of the invention, the mounting base extends vertically downward with a connecting arm, which is hinged to the middle section of a limiting arm. The hinge axis of the limiting arm is horizontal. A limiting roller is rotatably provided at the upper end of the limiting arm. The limiting roller is parallel to the hinge axis of the limiting arm, and its body abuts against the vertical surface of the outer side of one end of the connecting body. A limiting cylinder extends from the upper end of the driving cylinder and is sleeved outside the column. A driving cone is provided at the upper end of the limiting cylinder, and the driving cone is arranged with a larger upper section and a smaller lower section. A driving roller is provided at the lower end of the limiting arm, which is arranged parallel to the limiting roller, and the driving roller abuts against the outer wall of the driving cone.

[0023] The technical effects achieved by this invention are as follows:

[0024] During the actual construction of this steel structure support, a concrete embedded foundation is pre-constructed on the building base. A receiving groove is reserved on the concrete embedded foundation. The support base is hoisted into the receiving groove using hoisting equipment, and the support sleeve is hoisted onto the support base. The column is installed inside the support sleeve. The support sleeve can reliably support the column. When the drive mechanism drives the support sleeve to move vertically along the column, the support sleeve can support the column and ensure that the support sleeve and the support base are integrated into one, thus making the structure a stable whole.

[0025] A connector is installed at the upper end of the column, and one end of the crossbeam is horizontally connected to the connector. When the support sleeve moves vertically, the connector and the column form a stable whole, thus ensuring reliable support for the crossbeam. When the foundation deforms or an earthquake occurs, the crossbeam can slide on the connector, providing reliable vertical support for the crossbeam while allowing the crossbeam to undergo horizontal expansion and contraction. This effectively eliminates stress concentration at the connection between the crossbeam and the column. Therefore, this steel structure support ensures the stability of the connection between the column and the base, ensures reliable support of the column for the upper crossbeam, avoids slippage caused by the fixed connection between the upper end of the column and one end of the crossbeam, and ensures the stability of the column's support for the crossbeam.

[0034] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0035] The following is in conjunction with the appendix Figures 1 to 11 The steel structure support structure of the present invention will be described in detail below:

[0036] In existing prefabricated steel structure residential buildings, especially mid-rise or high-rise buildings, the columns are generally cylindrical during construction. An installation cap with circumferential holes is installed at the lower end of the column. During construction, the column is hoisted to the base using lifting equipment, and pre-embedded bolts are passed through the holes in the installation cap. The column is then fixed to the base by tightening the bolts. However, this construction method presents difficulties in hoisting and installing the pre-embedded bolts and the column, requiring repeated alignment and making installation inconvenient. Furthermore, because the column supports the entire steel structure, it bears the load applied by the steel beams. While the column is subjected to vertical stress, there is also horizontal stress. When the horizontal stress on the column is uneven, it is easy to cause wear at the connection between the column and the base. With the increase of service life, the pre-embedded bolts between the column and the base may bend and deform, which may lead to the risk of connection instability between the column and the base. In addition, the joint between the upper end of the column and the steel beam is welded or bolted. Therefore, when the foundation settles or other natural disasters occur, stress concentration may occur at the joint of the beam, resulting in tearing and failure of the connection between the column and the beam.

[0037] In response, this invention proposes a steel structure support structure, comprising:

[0038] A support base 100 is disposed within the concrete pre-embedded foundation 500, and the support base 100 is connected to the receiving groove on the concrete pre-embedded foundation 500.

[0039] The support sleeve 200 is vertically inserted into the support base 100.

[0040] The column 300 is disposed within the support sleeve 200, and the support sleeve 200 provides support for the outer surface of the column 300.

[0041] The connector 400 is located at the upper end of the column 300, and one end of the crossbeam 700 is in a horizontal sliding fit with the connector 400.

[0042] The drive mechanism drives the support sleeve 200 to move vertically along the column 300, and the connecting body 400 is fixedly connected to the upper end of the column 300.

[0043] In one embodiment, the contour of the receiving groove of the pre-embedded concrete foundation 500 can be a cylinder or a cuboid, which can effectively limit the support base 100 to ensure that the pre-embedded concrete foundation 500 reliably supports the support base 100 and prevent the support base 100 from tilting.

[0044] In one embodiment, the support sleeve 200 and the column 300 are in the shape of a cylindrical tube. After the support sleeve 200 and the support base 100 are integrated, the support base 100 can reliably support the support sleeve 200 and prevent the support sleeve 200 from tilting. Furthermore, the support sleeve 200 is fitted over the column 300 and can reliably support the column 300 in real time.

[0045] In one embodiment, the crossbeam 700 is mounted on the connector 400, and one end of the crossbeam 700 and the connector 400 form a horizontal sliding fit. When the drive mechanism drives the support sleeve 200 to move vertically and combine with the support base 100, the connector 400 can be linked to the upper end of the column 300 for fixation, thereby ensuring a stable connection between the connector 400 and the column 300. This facilitates the detachable connection between the crossbeam 700 and the upper end of the column 300. Moreover, since the crossbeam 700 and the connector 400 slide together, when the foundation settles or other natural disasters occur, the crossbeam 700 and the column 300 are in a movable connection. The column 300 can also provide reliable vertical support for the crossbeam 700. The column 300 can also be in a horizontally movable state on the crossbeam 700, thereby eliminating the concentrated stress between the crossbeam 700 and the column 300 and avoiding the problem of connection failure between the crossbeam 700 and the column 300.

[0046] In one embodiment, to ensure the secure clamping of the support sleeve 200 to the column 300, and to ensure reliable support for the column 300 and to avoid steel structure connection defects such as tilting of the column 300, a clamping unit is provided at the upper end of the support sleeve 200. The clamping unit is used to drive the support sleeve 200 to clamp the outer surface of the column 300.

[0047] In one embodiment, to ensure that the support sleeve 200 and the support base 100 are integrated, a limiting unit is provided between the support base 100 and the support sleeve 200. The driving mechanism drives the support sleeve 200 to move vertically along the support base 100. When the support sleeve 200 moves vertically to the lowest point, the driving mechanism drives the support sleeve 200 to rotate, and the limiting unit fixes the position of the support sleeve 200.

[0048] In one embodiment, after the column 300, the support base 100 and the support sleeve 200 are installed, the support sleeve 200 is driven to move vertically downward along the support sleeve 200 by the drive mechanism, and the support sleeve 200 is also driven to rotate, so that the limiting unit between the support sleeve 200 and the support base 100 is engaged. The limiting unit can perform positioning of the support sleeve 200 in the lower position to ensure that the support sleeve 200 and the support base 100 are integrated as one unit, thereby ensuring reliable support for the column 300.

[0049] In one embodiment, to ensure support for the support sleeve 200 and enable the support base 100 to be stably placed in the receiving groove on the pre-embedded foundation 500, thereby ensuring reliable support for the column 300, the support base 100 is generally columnar in shape and has a cylindrical cavity. The support sleeve 200 is inserted into the cylindrical cavity. The limiting unit includes a limiting protrusion 210 disposed on the outer wall of the support sleeve 200. The support base 100 is provided with a vertical slide rail 110 and a horizontal limiting slide rail 120. The lower end of the vertical slide rail 110 is connected to one end of the horizontal limiting slide rail 120. The vertical slide rail 110 and the horizontal limiting slide rail 120 allow the limiting protrusion 210 to pass through. The driving mechanism drives the support sleeve 200 to move vertically and rotate, and also drives the limiting protrusion 210 to move and rotate along the vertical slide rail 110 into the horizontal limiting slide rail 120.

[0050] In one embodiment, the vertical slide 110 allows the limiting protrusion 210 outside the support sleeve 200 to pass through and descend vertically to the lower end of the vertical slide 110. After moving to the lower end of the vertical slide 110, the support base 100 is rotated, causing the limiting protrusion 210 to rotate into the horizontal limiting slide 120, so that the limiting protrusion 120 abuts against the upper and lower surfaces of the horizontal slide 120, thereby achieving the locking of the support base 100 on the support sleeve 200 and ensuring that the support base 100 and the support sleeve 200 are combined into a whole.

[0051] In one embodiment, the horizontal limiting slide 120 is an arc-shaped opening in the circumferential direction of the support base 100. This opening can limit the limiting protrusion 210 so that the support base 100 and the support sleeve 200 are combined to form a whole.

[0052] In one embodiment, multiple sets of limiting protrusions 210 are arranged along the circumferential direction of the outer wall of the support sleeve 200, and the limiting protrusions 210 are spaced apart along the length direction of the outer wall of the support sleeve 200. The position and length of the vertical slide rail 110 correspond to the position of the limiting protrusions 210, and the position and length of the horizontal limiting slide rail 120 correspond to the position and rotation angle of the limiting protrusions 210. The upper side of the horizontal limiting slide rail 120 is provided with a first limiting surface 121 and a second limiting surface 122. The first limiting surface 121 and the second limiting surface 122 are arranged vertically, and there is an arc transition between the first limiting surface 121 and the second limiting surface 122. The upper plate surface of the limiting protrusion 210 abuts against the first limiting surface 121 or the second limiting surface 122.

[0053] In one embodiment, four sets of limiting protrusions 210 are arranged at intervals along the circumferential direction of the support sleeve 200, and the four sets of limiting protrusions 210 are arranged at intervals along the length direction of the support sleeve 200. Therefore, when the limiting protrusions 210 rotate and rotate into the horizontal limiting slide 120, the limiting protrusions 210 rotate from the first limiting surface 121 to the second limiting surface 122, and the limiting protrusions 210 fit against the second limiting surface 122, thereby enabling real-time engagement between the support sleeve 200 and the support base 100. The limiting protrusions 210 are arranged along the height direction of the support sleeve 200, so that the support sleeve 200 and the support base 100 can form multiple engagement limiting positions in the length direction, which can ensure the reliability of the support base 100 in limiting the support sleeve 200, and thus ensure the reliability of the support base 100 in supporting the support sleeve 200 in the length direction.

[0054] In one embodiment, in order to implement the clamping of the upper end of the support sleeve 200 to the column 300 and ensure reliable support for the column 300, the outer wall of the support sleeve 200 is provided with a through opening along the longitudinal direction. Multiple sets of through openings are provided along the circumferential direction of the support sleeve 200. The through openings divide the support sleeve 200 into multiple sets of tube flaps, and the limiting protrusions 210 are respectively installed on their respective tube flaps.

[0055] The clamping unit includes a clamping support ring 220 disposed on the outer ring of the upper end of the support sleeve 200. A sliding rod 230 is disposed at the upper end of the valve body. The sliding rod 230 is horizontal and arranged radially along the support sleeve 200. The sliding rod 230 and the clamping support ring 220 are in sliding engagement. A clamping spring 231 is sleeved on the extended end of the sliding rod 230. The two ends of the clamping spring 231 abut against the sliding rod 230 and the support sleeve 200, respectively. The support sleeve 200... A clamping drive block 240 is horizontally extended at the upper end of the support base 100. The outer surface of the clamping drive block 240 is provided with a first vertical surface 241 and a second vertical surface 242. The first vertical surface 241 and the second vertical surface 242 are connected by an inclined surface 243. The drive mechanism includes a drive cylinder 600 sleeved on the support base 100. The drive cylinder 600 is vertical and its inner wall abuts against the first vertical surface 241 or the second vertical surface 242, and drives the tube valve body to move in the radial direction.

[0056] In one embodiment, four sets of through openings are arranged along the circumferential direction of the support sleeve 200, thereby dividing the support sleeve 200 into four sets of tube flaps. When the drive cylinder 600 moves vertically downward, the drive inclined surface of the inner wall of the drive cylinder 600 transitions from the first vertical surface 241 to the second vertical surface 242, causing the clamping drive block 240 to slide along the sliding rod 230, thereby causing the four sets of tube flaps to approach each other in the radial direction, thus enabling the four sets of tube flaps to clamp the column 300, ensuring the reliability of the support sleeve 200 in supporting the column 300.

[0057] In one embodiment, to ensure that the drive cylinder 600 is integrated with the entire embedded foundation 500, the receiving groove of the concrete embedded foundation 500 is generally constricted. The edge of the receiving groove is provided with receiving openings 510. Multiple sets of receiving openings 510 are spaced apart along the circumferential direction of the edge of the receiving groove. The lower end of the drive cylinder 600 is provided with a snap-fit ​​flange 610. The snap-fit ​​flange 610 is arranged corresponding to the receiving opening 510. The drive cylinder 600 drives the support sleeve 200 to move and rotate vertically, so that the snap-fit ​​flange 610 passes through the receiving opening 510 and abuts against the edge of the receiving groove.

[0058] In one embodiment, the drive cylinder 600 is sleeved on the column 300, and the upper end of the drive cylinder 600 is engaged with the upper end of the support sleeve 200. The drive mechanism includes a set of hydraulic push rods. After all components are installed, the hydraulic push rods are activated, causing the drive cylinder 600 to move downwards along the column 300, which in turn moves the support sleeve 200 vertically until the support sleeve 200 descends to its lowest point. The lower end of the drive cylinder 600 engages with the flange 610, which passes through the receiving opening 510. The rotary motor of the drive mechanism is then activated to rotate the drive cylinder 600, thereby rotating the support sleeve. Rotating the support sleeve 200 allows the limiting protrusion 210 to rotate from the first limiting surface 121 to the second limiting surface 122, and the snap-fit ​​flange 610 to rotate into the receiving groove of the concrete pre-embedded foundation 500, thus limiting the snap-fit ​​flange 610 and ensuring that the drive cylinder 600 and the receiving groove of the concrete pre-embedded foundation 500 are integrated, and ensuring the overall support of the support sleeve 200 and the support base 100, so that the drive cylinder 600, the support base 100 and the support sleeve 200 and the concrete pre-embedded foundation 500 form a whole.

[0059] In one embodiment, for the installation of the crossbeam 700 and the column 300, a mounting base 310 is provided at the upper end of the column 300, and a snap-fit ​​groove 320 is provided on the mounting base 310. The snap-fit ​​groove 320 is rectangular in shape, and multiple sets of snap-fit ​​grooves 320 are spaced apart along the circumferential direction of the mounting base 310. The connector 400 is installed in the snap-fit ​​groove 320.

[0060] In one embodiment, four sets of snap-fit ​​grooves 320 are evenly distributed along the circumferential direction of the mounting base 310. When the crossbeam 700 is installed in the snap-fit ​​groove 320 through the connector 400, the crossbeam 700 can apply a uniform load to the column 300.

[0061] In one embodiment, the connector 400 is generally in the shape of a right-angled folded plate. One end of the connector 400 is vertically engaged in the engaging groove 320, and the vertical side of the connector 400 is in contact with the groove wall of the engaging groove 320. The other end of the connector 400 is horizontal and is provided with an engaging end 410. One end of the crossbeam 700 is inserted into the engaging end 410, and the crossbeam 700 and the engaging end 410 form a horizontal sliding fit. A support roller 330 is also extended on the mounting base 310. The horizontal side of the other end of the connector 400 abuts against the support roller 330. The support roller 330 is horizontal and is provided in multiple sets at intervals along the extension direction of the horizontal side of the other end of the connector 400.

[0062] In one embodiment, the snap-fit ​​end 410 can provide reliable support for one end of the crossbeam 700, and one end of the crossbeam 700 can be in a sliding state on the snap-fit ​​end 410 to ensure sliding support for one end of the crossbeam 700.

[0063] In one embodiment, the mounting base 310 has a connecting arm 340 extending vertically downward. The connecting arm 340 is hinged to the middle section of the limiting arm 350. The hinge axis of the limiting arm 350 is horizontal. A limiting roller 351 is rotatably provided at the upper end of the limiting arm 350. The limiting roller 351 is parallel to the hinge axis of the limiting arm 350, and its body abuts against the vertical surface of the outer side of one end of the connecting body 400. A limiting cylinder 620 extends from the upper end of the driving cylinder 600. The limiting cylinder 620 is sleeved outside the column 300. A driving cone 621 is provided at the upper end of the limiting cylinder 620. The driving cone 621 is arranged with a larger upper part and a smaller lower part. A driving roller 352 is provided at the lower end of the limiting arm 350 and is arranged parallel to the limiting roller 351. The driving roller 352 abuts against the outer wall of the driving cone 621.

[0064] In one embodiment, when the hydraulic jack drives the drive cylinder 600 to move downward, the drive cone 621 drives the limiting arm 350 to rotate around the axis, thereby causing the limiting roller 351 to abut against the outer vertical surface of one end of the connecting body 400, so as to implement a fixed connection between the connecting body 400 and the upper end of the column 300, and to ensure the reliability of the connection between the crossbeam 700 and the upper end of the column 300.

[0065] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
