Description

Technical Field

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

[0002] A steel structure is a structure made of steel materials. During the construction of a building project, steel structures are inevitably needed, and during the erection of a steel structure, support devices are required to support and connect the horizontal and vertical beams of the steel structure.

[0003] For example, patent application number CN202210197737.1 discloses a steel structure column with multiple support plates, relating to the field of steel structure technology. It includes: a main body; the main body being the steel structure column body; an auxiliary structure inside an inner groove formed within the main body; a limiting structure at the outer end of the adjusting structure; and a control structure at the middle position of the main body's periphery. When supported by the steel structure column, the top of the main body is aligned with the support position. By pulling the support member, the support member rotates via a rotating column, causing the limiting member to rotate. The limiting member then rotates via a rotating shaft, causing the adjusting member to rotate within the tilting groove. After adjusting the position, the support member is fixed to the support position via bolts through threaded holes. This increases the area between the top of the main body and the area requiring support, resulting in better fixation. This solves the problem of the inconvenient contact area at the top of the column, which necessitates multiple columns for supporting large areas, thus affecting usable space.

[0004] Existing steel structure support devices, such as those mentioned above, mostly use bolts for connection when supporting and connecting horizontal and vertical beams. This requires repeated bolt tightening steps, which slows down the connection speed of the support device to the horizontal and vertical beams, thus reducing the efficiency of the construction project. Summary of the Invention

[0005] In view of this, the present invention provides a steel structure support device to solve the problem that when the support device supports and connects horizontal and vertical beams, the connection method is mostly by bolt locking, which requires repeated bolt locking steps, thus resulting in a slow connection speed of the support device for horizontal and vertical beams.

[0008] Furthermore, after the connecting beam is installed on the support member, the positioning bolt will be indirectly locked into the locking screw hole; the outer end of the positioning bolt is provided with a follower gear; the follower gear is meshed with and connected to the drive rack; the bottom of the support member is provided with a guide connecting groove; after the connecting beam is installed on the support member, the snap-fit ​​positioning block will sequentially pass through the guide connecting groove and the guide through groove to snap into the interior of the snap-fit ​​positioning groove; the outer side of the support member is provided with a guide travel plate.

[0009] Furthermore, a guide stroke groove is provided at the top of the guide stroke plate; a force transmission component is provided inside the guide stroke groove; the bottom outer end of the force transmission component has an inclined structure; the inclined surface at the bottom of the force transmission component is in contact with the inclined surface at the top of the trigger push rod; one end of the support spring C is embedded in the inner side of the force transmission component; the other end of the support spring C is embedded in the inner wall of the guide stroke groove; a plug-in positioning rod is installed on the force transmission component; after the connecting crossbeam is installed on the support support component, the plug-in positioning rod will indirectly insert into the interior of the plug-in positioning groove.

[0010] Furthermore, the inner end of the force transmission component is provided with a bending push block; the bending push block has a rectangular structure; when the support and lifting component and the connecting beam move downward, the inclined surface of the trigger push rod will push the inclined surface of the force transmission component; when the inclined surface of the force transmission component is pushed, the force transmission component will drive the bending push block to move inward along the guide stroke groove; the top of the support and lifting component is symmetrically provided with snap-fit ​​bending pieces; the snap-fit ​​bending pieces are located inside the bending push block; after the connecting beam is installed on the support and lifting component, the snap-fit ​​bending pieces will be inserted into the snap-fit ​​positioning groove; a bending auxiliary groove is opened on the inner side of the snap-fit ​​bending pieces; when the bending push block moves inward, the bending push block will push the snap-fit ​​bending pieces inward; when the snap-fit ​​bending pieces are pushed inward by the bending push block, the snap-fit ​​bending pieces will start to bend from the position of the bending auxiliary groove. Beneficial effects

[0011] (i) After the connecting beam is hoisted onto the support support, the connecting beam will press down on the support support using its own weight, causing the support support to begin to descend under force. During this descent, the locking bolt will begin to rotate due to the cooperation of multiple structures, so that the locking bolt is inserted into the locking screw hole through rotation and locking, thus locking and fixing the connecting beam onto the support and the support vertical beam, achieving the purpose of stable connection of the horizontal and vertical beams.

[0012] (ii) After the connecting beam is hoisted onto the support support, the snap-fit ​​bent piece will be inserted into the snap-fit ​​positioning groove. When the support support begins to descend, the force transmission component will drive the bending push block to move inward with the cooperation of multiple structures. This causes the bending push block to push the snap-fit ​​bent piece inward, causing the snap-fit ​​bent piece to bend from the bending auxiliary groove due to the push. Thus, the bent snap-fit ​​bent piece is used to snap-fit ​​and fix the connecting beam, further improving the stability of the support device for the horizontal and vertical beams.

[0013] (iii) When the force transmission component moves inward, the force transmission component will also drive the insertion positioning rod to move inward, so that the insertion positioning rod can be inserted into the insertion positioning groove to fix the connecting crossbeam, thereby further enhancing the connection reliability between the horizontal and vertical beams and fully ensuring the quality of the steel structure built by this support device.

[0014] (iv) After the supporting support and connecting beam move downward to a certain position, the snap-fit ​​positioning block will indirectly snap into the interior of the snap-fit ​​positioning groove through the guide connecting groove and the guide through groove, thereby snapping and fixing the connecting beam, realizing the final positioning of the connecting beam, and making the connecting beam and the supporting vertical beam fully connected. Compared with the traditional method of simply locking with bolts, it is more stable and faster.

[0015] (v) Through structural improvements, this invention enables the support device to have four connection methods for horizontal and vertical beams: locking, buckling, plugging, and snapping. The combination of these four connection methods can fully ensure the stability of the support device for the connection of horizontal and vertical beams. At the same time, this device can automatically trigger the four connection methods by utilizing the self-weight of the connecting beam, ensuring connection stability without making the connection steps cumbersome, thus improving both connection efficiency and connection quality.

[0029] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention. Example

[0030] A steel structure support device, such as Figure 1-10As shown: It includes a supporting vertical beam 1 and a connecting horizontal beam 2. A support member 3 is installed on the outer wall of the supporting vertical beam 1 to facilitate the installation of the mounting member 301 and the trigger push rod 303. The bottom left and right ends of the connecting horizontal beam 2 have snap-fit ​​positioning grooves 201 to facilitate the insertion of the snap-fit ​​bending piece 3023 into the interior of the connecting horizontal beam 2. The left and right ends of the front and rear sides of the connecting horizontal beam 2 have insertion positioning grooves 202 to facilitate the insertion of the insertion positioning rod 3021 into the interior of the connecting horizontal beam 2. The front and rear sides of the connecting horizontal beam 2 have locking screw holes 203 to facilitate the locking of the positioning bolt 3014. The connecting beam 2 is tightly fitted into its interior. A snap-fit ​​positioning groove 204 is provided inside the connecting beam 2 to facilitate the snap-fit ​​positioning block 3010 engaging with the interior of the connecting beam 2. A guide groove 205 is provided at the bottom of the connecting beam 2 to facilitate the snap-fit ​​positioning block 3010 engaging with the interior of the snap-fit ​​positioning groove 204. The guide groove 205 is connected to the snap-fit ​​positioning groove 204. An mounting component 301 is provided on the support member 3 to facilitate the creation of mounting grooves 302. Mounting grooves 302 are provided on the four outer walls of the mounting component 301 to facilitate the installation of the support member 3011. A support sling 3011 is slidably installed inside the mounting slot 302. The support sling 3011 is designed to facilitate connection with the connecting beam 2, making it easier to connect the connecting beam 2 and the supporting vertical beam 1. The connecting beam 2 can be mounted on the support 3 via the support sling 3011. Trigger push rods 303 are located at the four corners of the top of the support 3. The trigger push rods 303 are designed to convert the downward force of the support sling 3011 into an inward force, which is then supplied to the force transmission component 3019. The top of the trigger push rod 303 has an inclined structure. A loading connecting plate 304 is located at the bottom outer side of the trigger push rod 303. The loading connecting plate 304 is designed to facilitate the connection of the drive rack. 305 is installed; a drive rack 305 is provided at the outer end of the loading connecting plate 304. The drive rack 305 is provided to facilitate the conversion of the force of the support lifting member 3011 descending into rotational force and provide it to the positioning bolt 3014; positioning loading members 306 are provided on the four outer walls of the support member 3. The positioning loading members 306 are provided to facilitate the opening of the shrink slide 307; the top of the positioning loading member 306 is provided with the shrink slide 307; the shrink slide plate 308 is slidably installed inside the shrink slide 307. The shrink slide 307 is provided to facilitate the installation of the shrink slide plate 308; the shrink slide plate 308 has a rectangular structure. The shrink slide plate 308 is provided to facilitate the installation of the snap-fit ​​positioning block 3010;Each set of retractable sliding plates 308 is fitted with a support spring A309. The support spring A309 is designed to support the retractable sliding plates 308 when they are not in use. A snap-fit ​​positioning block 3010 is located at the top outer side of each retractable sliding plate 308. The snap-fit ​​positioning block 3010 is designed to securely engage the support support 3011 and the connecting beam 2. By hoisting the connecting beam 2 onto the support support 3011, the connecting beam 2 begins to press down on the support support 3011 under its own weight. This causes the support support 3011 to move the connecting beam 2 downwards. During this movement, the two ends of the guide groove 3016 on the support support 3011 push against the inclined surface of the snap-fit ​​positioning block 3010, thus engaging the positioning block 3010. The inclined plane pushes the retractable slide plate 308 inward along the retractable slide groove 307, causing the locking positioning block 3010 to temporarily retract and insert into the guide connecting groove 3016. As the support member 3011 and the connecting beam 2 continue to move downward, the locking positioning block 3010 inserts into the guide through groove 205. At this time, the retractable slide plate 308, under the action of the support spring A309, moves the locking positioning block 3010 outward along the retractable slide groove 307, causing the locking positioning block 3010 to engage with the locking positioning groove 204. Thus, the locking positioning block 3010 engages and positions the support member 3011, the connecting beam 2, the support member 3, and the support vertical beam 1. Example

[0031] Based on Example 1, such as Figure 1-10As shown: the outer end of the snap-fit ​​positioning block 3010 has an inclined structure; one end of the support spring B3012 is embedded in the bottom of the support member 3011, and the support spring B3012 is set to support the support member 3011 when it is not in use; the other end of the support spring B3012 is embedded in the bottom of the mounting groove 302; a mounting plate 3013 is installed on the support member 3011, and the mounting plate 3013 is set to facilitate the installation of the positioning bolt 3014; the mounting plate 3013 is provided with the positioning bolt 3014, and the positioning bolt 3014 is set to facilitate the locking and fixing of the connecting beam 2; after the connecting beam 2 is installed on the support member 3011, the positioning bolt 3014 will be indirectly locked and inserted into the locking screw hole 203; the outer end of the positioning bolt 3014 is provided with a follower gear 3. 015, the follower gear 3015 is designed to cooperate with the drive rack 305 to provide rotational force to the positioning bolt 3014, so that the positioning bolt 3014 can be fed and locked into the locking screw hole 203 by rotation. The follower gear 3015 is meshed with the drive rack 305. When the support member 3011 drives the connecting crossbeam 2 to move downward, because the follower gear 3015 is meshed with the drive rack 305, the follower gear 3015 will drive the positioning bolt 3014 to rotate under the action of the drive rack 305 when it follows the support member 3011 down. This allows the positioning bolt 3014 to be fed and inserted into the locking screw hole 203 by rotation, thereby locking and positioning the positions of the support member 3011, the connecting crossbeam 2, the support member 3, and the support vertical beam 1 through the positioning bolt 3014. Example

[0032] Based on Example 2, such as Figure 1-10As shown: The bottom of the support member 3011 is provided with a guide connecting groove 3016. The guide connecting groove 3016 is provided to facilitate the snap-fit ​​positioning block 3010 to pass through the support member 3011 and enter the guide through groove 205 and the snap-fit ​​positioning groove 204. After the connecting beam 2 is installed on the support member 3011, the snap-fit ​​positioning block 3010 will sequentially pass through the guide connecting groove 3016 and the guide through groove 205 and snap into the snap-fit ​​positioning groove 204. A guide travel plate 3017 is provided on the outer side of the support member 3. The guide travel plate 3017 is provided... The guide stroke groove 3018 is provided on the top of the guide stroke plate 3017 to facilitate the installation of the force transmission component 3019. The force transmission component 3019 is housed inside the guide stroke groove 3018 to facilitate the installation of the insertion positioning rod 3021 and the bending push block 3022. The bottom outer end of the force transmission component 3019 has an inclined structure. The inclined surface at the bottom of the force transmission component 3019 is parallel to the inclined surface at the top of the trigger push rod 303. The inclined surfaces are in close contact; one end of a support spring C3020 is embedded in the inner side of the force transmission component 3019. The support spring C3020 is designed to support the force transmission component 3019 when it is not in use; the other end of the support spring C3020 is embedded in the inner wall of the guide stroke groove 3018; a plug-in positioning rod 3021 is installed on the force transmission component 3019. The plug-in positioning rod 3021 is designed to facilitate the plugging and fixing of the connecting crossbeam 2; after the connecting crossbeam 2 is installed on the support support component 3011, the plug-in positioning rod 3021 will indirectly... When the support member 3011 and the connecting beam 2 move downward, the inclined surface of the trigger push rod 303 will push the inclined surface of the force transmission member 3019. Under the action of the inclined surface, the force transmission member 3019 will drive the insertion positioning rod 3021 to move inward along the guide stroke groove 3018, so that the insertion positioning rod 3021 can be inserted into the insertion positioning groove 202. Thus, the positions of the support member 3011, the connecting beam 2, the support member 3, and the support vertical beam 1 are inserted and fixed by the insertion positioning rod 3021. Example

[0033] Based on Example 3, such as Figure 1-10As shown: The inner end of the force transmission component 3019 is provided with a bending push block 3022. The bending push block 3022 is designed to push the snap-fit ​​bent piece 3023, making it easier to push the snap-fit ​​bent piece 3023 into an L-shaped structure to fix the connecting crossbeam 2. The bending push block 3022 has a rectangular structure. When the support member 3011 and the connecting crossbeam 2 move downward, the inclined surface of the trigger push rod 303 will push the inclined surface of the force transmission component 3019. When the inclined surface of the force transmission component 3019 is pushed, the force transmission component 3019 will drive the bending push block 3022 along the guide. The support member 3011 moves inward towards the travel groove 3018; symmetrical snap-fit ​​bending pieces 3023 are provided on the top of the support member 3011, which are designed to facilitate the snap-fit ​​fixing of the connecting beam 2; the snap-fit ​​bending pieces 3023 are located inside the bending push block 3022; after the connecting beam 2 is installed on the support member 3011, the snap-fit ​​bending pieces 3023 will be inserted into the snap-fit ​​positioning groove 201; a bending auxiliary groove 3024 is provided on the inner side of the snap-fit ​​bending pieces 3023, which is designed to facilitate the snap-fit ​​bending pieces 3022... 3. It is easier to be bent by the bending push block 3022; when the bending push block 3022 moves inward, it will push the buckle bending piece 3023 inward; when the buckle bending piece 3023 is pushed inward by the bending push block 3022, the buckle bending piece 3023 will start bending from the position of the bending auxiliary groove 3024. After the connecting beam 2 is installed on the support support 3011, the buckle bending piece 3023 will be inserted into the inside of the buckle positioning groove 201. When the force transmission member 3019 moves inward along the guide stroke groove 3018, the force transmission member 3019 moves inward along the guide stroke groove 3018. The force transmission component 3019 will drive the bending push block 3022 to move inward. Since the bending push block 3022 is located outside the snap-fit ​​bending piece 3023, when the bending push block 3022 moves inward, it will push the snap-fit ​​bending piece 3023, so that the snap-fit ​​bending piece 3023 will start to bend from the position of the bending auxiliary groove 3024 after being pushed, and bend the snap-fit ​​bending piece 3023 into an L-shaped structure. Thus, the snap-fit ​​bending piece 3023 is used to snap-fit ​​and fix the positions of the support support 3011, the connecting crossbeam 2, the support 3, and the support vertical beam 1.

[0034] The specific usage and function of this embodiment are as follows: In use, the supporting vertical beam 1 is first erected. After erection, the connecting horizontal beam 2 is hoisted onto the supporting support member 3011 using hoisting equipment. The snap-fit ​​bent piece 3023 is then inserted into the snap-fit ​​positioning groove 201. Simultaneously, the connecting horizontal beam 2, under its own weight, begins to press down on the supporting support member 3011, causing the supporting support member 3011 to move the connecting horizontal beam 2 downwards. During this movement, the two ends of the guide connecting groove 3016 on the supporting support member 3011 push against the inclined surface of the locking positioning block 3010. This causes the locking positioning block 3010, pushed by the inclined surface, to begin moving the retractable sliding plate 308 along the retractable sliding groove 307 towards the opposite direction. The internal movement causes the locking positioning block 3010 to temporarily retract and insert into the guide connecting groove 3016. As the support member 3011 and the connecting beam 2 continue to move downwards, the locking positioning block 3010 will insert into the guide through groove 205. At this time, the retracting slide plate 308, under the action of the support spring A309, can drive the locking positioning block 3010 to move outwards along the retracting slide groove 307, causing the locking positioning block 3010 to engage with the locking positioning groove 204. Thus, the locking positioning block 3010 engages and positions the support member 3011, the connecting beam 2, the support member 3, and the support vertical beam 1. Furthermore, when the support member 3011 drives the connecting beam 2 downwards... Because the follower gear 3015 meshes with the drive rack 305, the follower gear 3015 will drive the positioning bolt 3014 to rotate under the action of the drive rack 305 when it follows the support member 3011 as it descends. This causes the positioning bolt 3014 to begin feeding and inserting into the locking screw hole 203 through rotation. Thus, the positioning bolt 3014 locks and positions the support member 3011, the connecting crossbeam 2, the support member 3, and the support vertical beam 1. At the same time, the inclined surface of the trigger push rod 303 will push the inclined surface of the force transmission member 3019. Under the action of the inclined surface, the force transmission member 3019 will drive the insertion positioning rod 3021 to move inward along the guide stroke groove 3018, thus achieving insertion positioning. Rod 3021 can be inserted into the insertion positioning groove 202, thereby fixing the positions of the support member 3011, the connecting crossbeam 2, the support member 3, and the support vertical beam 1 through the insertion positioning rod 3021. When the force transmission member 3019 moves inward along the guide stroke groove 3018, the force transmission member 3019 will drive the bending push block 3022 to move inward. Since the bending push block 3022 is located outside the snap-fit ​​bending piece 3023, when the bending push block 3022 moves inward, it will push the snap-fit ​​bending piece 3023, so that the snap-fit ​​bending piece 3023 will start to bend from the position of the bending auxiliary groove 3024 after being pushed, bending the snap-fit ​​bending piece 3023 into an L-shaped structure.The bent snap-fit ​​piece 3023 secures the support member 3011, the connecting beam 2, the support member 3, and the supporting vertical beam 1, thus completing the reliable connection between the connecting beam 2 and the support member 3 and the supporting vertical beam 1.
