Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a modular quick connection node for steel beams and an assembly method thereof. Background Technology

[0002] Integrated jacking formwork systems (building rigs) are frequently used in the wall construction of super high-rise or high-rise buildings due to their advantages in safety and efficiency. Currently, the steel beam platforms on top of these rigs are generally welded connections, which prevents the platforms from being reused and reduces their economic efficiency. If conventional bolted connections are used for the steel beams, problems arise such as numerous node connection plates, inconvenience in installing connection plates at high altitudes, and higher installation risks, significantly reducing the installation efficiency of the jacking platform.

[0003] Therefore, improving the efficiency, safety, and portability of steel beam platform installation is a problem that needs to be solved in this field. Summary of the Invention

[0004] To address the aforementioned technical problems in the installation of existing steel beam platforms, the present invention aims to provide a modular rapid connection node and assembly method for steel beams. By innovatively employing integrated steel beam node connectors and a web plate integrally formed on the web of the main steel beam, the connectors can be retracted into the secondary beams during hoisting. After the steel beams are in place, the connectors extend to the connection position, significantly improving the efficiency of the steel beam bolt connection method and the portability of high-altitude installation. This ensures the rapid installation and safe and reliable construction of the building construction platform, while also meeting the turnover requirements of the steel platform.

[0005] To achieve the above objectives, the present invention provides a modular quick-connection node for steel beams, comprising a main steel beam, several secondary steel beams, and several connectors.

[0006] The main steel beam and the secondary steel beam are I-beams.

[0007] The web of the main steel beam is vertically connected with several web connecting plates, and each web connecting plate has an insertion gap at both ends that mates with the upper and lower flanges of the main steel beam.

[0008] The web end of one end of the secondary steel beam and the contact area between the upper and lower flanges of the secondary steel beam are respectively provided with mounting slots that mate with the connecting parts.

[0009] The connector consists of a main steel beam connector and a secondary steel beam connector.

[0010] The main steel beam connecting part on the connector is matched with the web connecting plate and the insertion gap on the main steel beam, and can be inserted into the insertion gap and connected and assembled with the web connecting plate and the flange of the main steel beam.

[0011] The secondary steel beam connecting part on the connector mates with the slot at one end of the secondary steel beam, and can be movably inserted into the slot and assembled with one end of the secondary steel beam.

[0012] The connector can move between a first position and a second position relative to one end of the secondary steel beam along the slot at one end of the secondary steel beam. When the connector moves to the first position, the connector retracts into one end of the secondary steel beam to form a hoisting state.

[0013] When the connector moves to the second position, the main steel beam connecting part on the connector extends out of one end of the secondary steel beam. The main steel beam connecting part can be fitted with the main steel beam with a clearance and inserted into the main steel beam as a whole. At the same time, the main steel beam connecting part of the connector is detachably connected to the web connecting plate and the flange of the main steel beam through fasteners. The secondary steel beam connecting part of the connector is detachably connected to one end of the secondary steel beam through fasteners, so that one end of the secondary steel beam directly abuts against the main steel beam to form a fixed docking structure.

[0014] Furthermore, the main steel beam includes two first flanges and a first web;

[0015] The two first flanges are respectively provided with a first bolt hole group and a second bolt hole group along the width direction. The first bolt hole group and the second bolt hole group are symmetrically distributed on both sides of the center line with the first web as the center line.

[0016] Furthermore, the plurality of web plate connecting plates are distributed equidistantly on the main steel beam. One side of the web plate connecting plate is perpendicularly connected to the first web of the main steel beam, and the upper and lower ends are respectively provided with insertion gaps to the two first flanges of the main steel beam. The insertion gaps can accommodate the main steel beam connecting part of the connector. The web plate connecting plate is vertically provided with a third bolt hole group, which is used to cooperate with the main steel beam connecting part of the connector.

[0017] Furthermore, the connector is an I-beam, which includes two second flanges and a second web. The two ends of the second web are respectively perpendicularly connected to the two second flanges, and the thickness of the second flange is adapted to the insertion gap and the insertion slot.

[0018] The second flange is convex in shape, including a flange main steel beam connection part with a wider transverse width and a flange secondary steel beam connection part with a narrower transverse width;

[0019] The second web includes the main web beam connection portion and the secondary web beam connection portion.

[0020] The flange main steel beam connection portion of the two second flanges and the web main steel beam connection portion constitute the main steel beam connection portion.

[0021] The flange main steel beam connecting parts of the main steel beam connecting portion are respectively inserted into the insertion gap between the web connecting plate and the two first flanges of the main steel beam. The outward end face of the two flange main steel beam connecting parts is respectively attached to the inward end face of the two first flanges. The flange main steel beam connecting part is provided with a fourth bolt hole group corresponding to the second bolt hole group along the length direction. The fourth bolt hole group and the second bolt hole group are connected by fasteners to fix the flange main steel beam connecting part to the first flange. The web main steel beam connecting part is attached to the web connecting plate as a whole. The web main steel beam connecting part is provided with a sixth bolt hole group corresponding to the third bolt hole group. The third bolt hole group and the sixth bolt hole group are connected by fasteners to fix the web main steel beam connecting part to the web connecting plate.

[0022] The flange secondary steel beam connection portion of the two second flanges and the web secondary steel beam connection portion constitute a secondary steel beam connection part. The flange secondary steel beam connection portion is provided with a fifth bolt hole group for connecting with the secondary steel beam. The web secondary steel beam connection portion fits into the web of the secondary steel beam and is provided with a seventh bolt hole group for connecting with the web of the secondary steel beam.

[0023] Furthermore, the secondary steel beam includes two third flanges and a third web;

[0024] The end of the third web plate is provided with a slot at the contact position with the two third flanges. The vertical height of the slot is adapted to the thickness of the second flange of the connector, and the two second flanges of the connector can be inserted. The horizontal length of the slot is greater than the vertical length of the second flange as a whole. In this way, the second flange can slide along the slot as a whole and be placed in the secondary steel beam to form the first position and form a hoisting state.

[0025] By moving the connector, the main steel beam connecting part of the connector extends outward from the slot to form a second position. The third flange is provided with an eighth bolt hole group corresponding to the fifth bolt hole group on the flange secondary steel beam connecting part. The fifth bolt hole group and the eighth bolt hole group are connected by fasteners to realize the fixed connection between the flange secondary steel beam connecting parts of the third flange and the second flange.

[0026] The third web plate is attached to the secondary steel beam connection of the second web plate. The third web plate is provided with a ninth bolt hole group corresponding to the seventh bolt hole group on the secondary steel beam connection. The ninth bolt hole group and the seventh bolt hole group are connected by fasteners to achieve a fixed connection between the third web plate and the secondary steel beam connection.

[0027] Furthermore, the secondary steel beam is perpendicular to the main steel beam, the ends of the two third flanges of the secondary steel beam are respectively connected to the side walls of the two first flanges of the main steel beam, the third web plate is attached to the side of the second web plate and the web plate connecting plate, and the end of the third web plate is connected to the end of the web plate connecting plate.

[0028] Furthermore, the connection node also includes a second connector, the two ends of which are connected to the main steel beam and the secondary steel beam respectively. The second connector includes a first connecting part and a second connecting part, and the first connecting part and the second connecting part are connected by a third connecting part.

[0029] The first connecting part and the second connecting part are respectively provided with bolt holes corresponding to the second bolt hole group on the first flange and the eighth bolt hole group on the third flange. The first connecting part is connected to the first flange of the main steel beam by fasteners, and the second connecting part is connected to the third flange of the secondary steel beam by fasteners. In order to achieve the above objectives, the assembly method of the modular quick connection node of the steel beam provided by the present invention is used for any of the above, and the assembly method includes:

[0030] S1: First, insert the two second flanges of the connector into the slots of the secondary steel beam, so that the connector is placed in the secondary steel beam and in the first position;

[0031] S2: Hoist the secondary steel beams and the connecting parts installed in the secondary steel beams onto the top steel platform;

[0032] S3: Move the connector so that the main steel beam connecting part of the connector extends out of the secondary steel beam and is located in the second position;

[0033] S4: Secure the secondary steel beam connecting part of the connector to the secondary steel beam using fasteners;

[0034] S5: Fix the main steel beam connecting part of the connector to the main steel beam and the web plate connecting plate respectively using fasteners;

[0035] S6: Select the appropriate second connector according to the requirements and fix the second connector to the main steel beam and the secondary steel beam respectively.

[0036] The modular rapid connection node and assembly method for steel beams provided by this invention can ensure the rapid installation and safe and reliable construction of the steel platform for building construction, while also meeting the turnover requirements of the steel platform.

[0037] Compared with existing technologies, the modular quick-connection node for steel beams provided by this invention has the following advantages:

[0038] (1) Modular design. Bolt holes are opened every 100mm on the steel beams for connecting the steel beams and the hanging frame below the platform panel, which can realize the installation of steel beam platform systems, platform steel plate systems and hanging frame systems with various modular specifications. Steel beam web connecting plates are set every 300~500mm on the steel beams to meet the installation of steel beams with different beam spacing and adapt to the steel platform structure requirements of different projects;

[0039] (2) Rapid installation. Conventional bolt splicing uses three separate steel plates as connecting plates. When installing at high altitudes, the three steel plates need to be positioned and installed separately, which involves many parts and is a cumbersome process. The integrated steel beam node connector combines the connecting plates of the upper and lower flanges and the web of the steel beam into one piece. During the hoisting stage, the connector can be retracted into the secondary beam and hoisted together with the secondary beam. After the steel beam is in place, the connector extends to the connection position, which greatly improves the efficiency of the bolt connection method of steel beams.

[0040] (3) High tolerance for error. The end plate connection method is prone to installation difficulties due to installation errors, and the on-site installation accuracy requirements are extremely high, but construction errors cannot be avoided on the construction site. Compared with the end plate connection method, this node can effectively avoid the phenomenon of installation difficulties caused by installation errors, and the node construction method is more in line with the mechanical characteristics of steel beam nodes;

[0041] (4) Reusability. Through modular design and bolted splicing nodes, the steel beams can be reusable, thereby improving the economy of the lifting platform and reducing costs and increasing efficiency in the construction of high-rise building projects. Attached Figure Description

Detailed Implementation

[0051] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0052] See Figure 1 The diagram shown is a structural schematic of the modular quick-connection node for steel beams provided by the present invention.

[0053] As shown in the figure, the modular quick connection node for steel beams provided by the present invention includes four components: a main steel beam 100, several secondary steel beams 200, several connectors 300, and several web plate connecting plates 400.

[0054] Among them, the main steel beam 100 and the secondary steel beam 200 are I-beams.

[0055] The web of the main steel beam 100 is vertically connected with several web connecting plates 400. Each web connecting plate 400 has an insertion gap 410 at both ends that mates with the upper and lower flanges of the main steel beam 100 and is designed to cooperate with the connector 300.

[0056] The web end of one end of the secondary steel beam 200 and the contact parts of the upper and lower flanges of the secondary steel beam 200 are respectively provided with mounting slots 230 that mate with the connector 300.

[0057] The connector 300 consists of a main steel beam connector and a secondary steel beam connector.

[0058] The main steel beam connecting part on the connector 300 cooperates with the web connecting plate 400 and the insertion gap 410 on the main steel beam 100, and can be inserted into the insertion gap 410, and connected and assembled with the web connecting plate 400 and the flange of the main steel beam 100.

[0059] The secondary steel beam connecting part on the connector 300 cooperates with the mounting slot 230 at one end of the secondary steel beam 200, is movably inserted into the mounting slot 230, and can be assembled with one end of the secondary steel beam 200.

[0060] The connector 300 can move between a first position and a second position relative to one end of the secondary steel beam 200 along the mounting slot 230 at one end of the secondary steel beam 200. When the connector 300 moves to the first position, the connector 300 is retracted into one end of the secondary steel beam 200 to form a hoisting state.

[0061] When the connector 300 moves to the second position, the main steel beam connecting part on the connector 300 extends out of one end of the secondary steel beam 200. The main steel beam connecting part can cooperate with the insertion gap 410 on the main steel beam 100 and be inserted into the main steel beam 100 as a whole. At the same time, the main steel beam connecting part of the connector 300 is detachably connected and assembled with the web connecting plate 400 and the flange of the main steel beam 100 through fasteners. The secondary steel beam connecting part of the connector 300 is detachably connected and assembled with one end of the secondary steel beam 200 through fasteners, so that one end of the secondary steel beam 200 directly abuts against the main steel beam 100 to form a fixed docking structure.

[0062] Specifically, the main steel beam 100 adopts an I-beam, which includes two first flanges 110 and a first web 120;

[0063] The two first flanges 110 are respectively provided with a first bolt hole group 130 and a second bolt hole group 140 along the width direction. The first bolt hole group 130 and the second bolt hole group 140 are symmetrically distributed on both sides of the center line with the first web 120 as the center line.

[0064] The first bolt hole group 130 and the second bolt hole group 140 are composed of a number of bolt holes. The bolt holes are distributed equidistantly along the length of the first flange 110. In this example, the bolt holes are preferably arranged at intervals of 100mm.

[0065] The first bolt hole group 130 is used for connecting the platform steel beam, platform panel and lower hanging frame, and the second bolt hole group 140 is used for connecting with the connector 300.

[0066] Several web plate connecting plates 400 are distributed equidistantly on the main steel beam 100. In this example, the web plate connecting plates 400 are preferably arranged at intervals of 300mm-500mm to meet the installation requirements of steel beams with different beam spacings and adapt to the steel platform structure requirements of different projects.

[0067] The web plate connecting plate 400 is generally square, with one side vertically connected to the first web plate 120 of the main steel beam 100. The upper and lower ends are respectively provided with insertion gaps 410 to the two first flanges 110 of the main steel beam 100. The insertion gaps 410 can accommodate the main steel beam connecting part of the connector 300. The web plate connecting plate 400 is vertically provided with a third bolt hole group 420, which is used to cooperate with the main steel beam connecting part of the connector 300 for connection.

[0068] In this example, the transverse length of the web connecting plate 400 is preferably the same as the length of the sidewall from the first web 120 to the first flange 110.

[0069] The connector 300 is an I-beam, which includes two second flanges 310 and a second web 320. The two ends of the second web 320 are perpendicularly connected to the two second flanges 310 respectively. The thickness of the second flanges 310 is adapted to the insertion gap 410 and the insertion slot 230 respectively.

[0070] like Figure 4 The second flange 310 is convex in shape, including a flange main steel beam connecting part 311 with a wider transverse width and a flange secondary steel beam connecting part 312 with a narrower transverse width.

[0071] The second web 320 includes a main web beam connection portion 321 and a secondary web beam connection portion 322.

[0072] The flange main steel beam connection portion 311 of the two second flanges 310 and the web main steel beam connection portion 321 constitute the main steel beam connection part.

[0073] The flange main steel beam connecting parts 311 in the main steel beam connecting part are respectively inserted into the insertion gaps 410 between the web connecting plate 400 and the two first flanges 110 of the main steel beam 100. The outward end faces of the two flange main steel beam connecting parts 311 are respectively abutted against the inward end faces of the two first flanges 110. The flange main steel beam connecting parts 311 are provided with a fourth bolt hole group 311a corresponding to the second bolt hole group 140 along the length direction. The fourth bolt hole group 311a and the second The bolt hole group 140 is connected by fasteners to fix the flange main steel beam connecting part 311 to the first flange 110; the web main steel beam connecting part 321 is in contact with the web connecting plate 400 as a whole, and the web main steel beam connecting part 321 is provided with a sixth bolt hole group 321a corresponding to the third bolt hole group 420. The third bolt hole group 420 and the sixth bolt hole group 321a are connected by fasteners to fix the web main steel beam connecting part 321 to the web connecting plate 400.

[0074] The flange secondary steel beam connecting portion 312 of the two second flanges 310 and the web secondary steel beam connecting portion 322 constitute the secondary steel beam connecting part. The flange secondary steel beam connecting portion 312 is provided with a fifth bolt hole group 312a for connecting with the secondary steel beam 200. The web secondary steel beam connecting portion 322 fits against the web of the secondary steel beam 200 and is provided with a seventh bolt hole group 322a for connecting with the web of the secondary steel beam 200.

[0075] The vertical length of the aforementioned flange main steel beam connection portion 311 is preferably the same as the length from the first web plate 120 to the side wall of the first flange 110, and the transverse width of the flange secondary steel beam connection portion 312 is preferably the same as the flange width of the secondary steel beam 200.

[0076] The secondary steel beam 200 is an I-beam, which includes two third flanges 210 and a third web 220;

[0077] At one end of the third web 220, there are mounting slots 230 at the contact positions with the two third flanges 210. The vertical height of the mounting slots 230 is adapted to the thickness of the second flanges 310 of the connector 300, allowing the two second flanges 310 of the connector 300 to be inserted. The lateral length of the mounting slots 230 is greater than the overall vertical length of the second flanges 310, so that the second flanges 310 can move as a whole along the mounting slots 230 and be integrally placed in the secondary steel beam 200 to form the first position, such as... Figure 3 It is now in a hoisting state;

[0078] like Figure 2 By moving the connector 300, the main steel beam connecting part of the connector 300 extends outward from the mounting slot 230 to form a second position. The third flange 210 is provided with an eighth bolt hole group 211 corresponding to the fifth bolt hole group 312a on the flange secondary steel beam connecting part 312. The fifth bolt hole group 312a and the eighth bolt hole group 211 are connected by fasteners to realize the fixed connection between the third flange 210 and the flange secondary steel beam connecting part 312 of the second flange 310.

[0079] The eighth bolt hole group 211 and the fifth bolt hole group 312a mentioned above are each composed of a number of bolt holes. The number of bolt holes in the eighth bolt hole group 211 is greater than that in the fifth bolt hole group 312a. The extra bolt holes are used for the connection of platform steel beams, platform panels and lower hanging frame, etc.

[0080] The third web plate 220 is fitted with the web plate secondary steel beam connection portion 322 of the second web plate 320. The third web plate 220 is provided with a ninth bolt hole group 221 corresponding to the seventh bolt hole group 322a on the web plate secondary steel beam connection portion 322. The ninth bolt hole group 221 and the seventh bolt hole group 322a are connected by fasteners to achieve a fixed connection between the third web plate 220 and the web plate secondary steel beam connection portion 322.

[0081] To further improve the stability and reliability of the connection, the secondary steel beam 200 in this scheme is perpendicular to the main steel beam 100, and the ends of the two third flanges 210 of the secondary steel beam 200 are respectively connected to the side walls of the two first flanges 110 of the main steel beam 100, which can improve the connection reliability.

[0082] The third web plate 220 is attached to the side where the second web plate 320 and the web plate connecting plate 400 are attached, and the end of the third web plate 220 is connected to the end of the web plate connecting plate 400.

[0083] In this scheme, the third bolt hole group 420, the fourth bolt hole group 311a, the sixth bolt hole group 321a and the seventh bolt hole group 322a are all composed of several bolt holes, and the bolt holes are distributed at equal intervals along the length.

[0084] This solution, through the structural design of the slot 230, allows the connector 300 to be inserted into the slot 230 before hoisting, so that the connector 300 is placed in the secondary steel beam 200 as a whole. Then, the secondary steel beam is hoisted to the top steel beam platform. After it arrives, the connector 300 is moved along the slot 230 and extended to the second position for node connection, which greatly improves the efficiency of the steel beam bolt connection method.

[0085] Meanwhile, compared to end plate connections, this node effectively avoids installation difficulties caused by installation errors, and its construction method is more in line with the mechanical characteristics of steel beam nodes. The application of this node ensures the rapid installation and safe and reliable construction of the building construction machine's steel platform, while also meeting the platform's reusability requirements.

[0086] This solution does not limit the fasteners mentioned above, and can be determined according to actual needs. As an example, in this instance, bolts and nuts are preferred, and the bolts and nuts are connected by threads to achieve fixation.

[0087] To further improve the connection reliability of the connection nodes, such as Figure 5 The solution also includes a second connector 500, with its two ends connected to the main steel beam 100 and the secondary steel beam 200 respectively. The main steel beam 100 and the secondary steel beam 200 are connected by the second connector 500 to further improve the reliability of the connection node.

[0088] The second connector 500 includes a first connecting part 510 and a second connecting part 520, wherein the first connecting part 510 and the second connecting part 520 are connected by a third connecting part 530.

[0089] The first connecting part 510 and the second connecting part 520 are respectively provided with bolt holes corresponding to the second bolt hole group 140 on the first flange 110 and the eighth bolt hole group 211 on the third flange 210.

[0090] Thus, the first connecting part 510 of the second connecting member 500 is connected to the first flange 110 of the main steel beam 100 by fasteners, and the second connecting part 520 of the second connecting member 500 is connected to the third flange 210 of the secondary steel beam 200 by fasteners, thereby realizing the connection between the main steel beam 100 and the secondary steel beam 200.

[0091] This solution does not limit the structure of the third connecting part 530, which can be determined according to actual needs. As an example, in this example, the third connecting part 530 adopts an L-shaped connector.

[0092] Furthermore, this solution does not limit the number of second connectors 500, which can be selected according to actual needs. For example, when rapid connection is required, the connection of second connectors 500 can be omitted to achieve rapid connection. If the stability and reliability requirements of the structure are high, four second connectors 500 can be used between the main steel beam 100 and the secondary steel beam 200. The four second connectors 500 are symmetrically located on both sides of the two third flanges 210 in the secondary steel beam 200. Of course, one, two or three second connectors 500 can also be used between the main steel beam 100 and the secondary steel beam 200 as needed.

[0093] For the modular quick-connection node of the steel beam given in this example, this example also provides a corresponding assembly scheme.

[0094] Step 1: First, insert the two second flanges 310 of the connector 300 into the mounting slots 230 of the secondary steel beam 200, so that the connector 300 is fully installed in the secondary steel beam 200 and located in the first position;

[0095] Step 2: Hoist the secondary steel beam 200 and the connecting parts 300 installed in the secondary steel beam onto the top steel platform;

[0096] Step 3: Move connector 300 so that the main steel beam connecting part of connector 300 extends out of the secondary steel beam 200 and is located in the second position;

[0097] Step 4: Secure the secondary steel beam connecting part of connector 300 to secondary steel beam 200 using fasteners;

[0098] Step 5: Secure the main steel beam connecting part of connector 300 to the main steel beam 100 and web connecting plate 400 respectively using fasteners;

[0099] Step 6: Select the appropriate second connector 400 according to the requirements and fix the second connector 400 to the main steel beam 100 and the secondary steel beam 200 respectively.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
