Description

Technical Field

[0001] This invention relates to the field of building structure connection node technology, and in particular to a fully bolted column connection node and building. Background Technology

[0002] In architectural and structural engineering, the design of connection nodes is a key factor in ensuring the overall performance, stability, and durability of a structure. With the continuous development of modern building technology, the requirements for connection nodes are also increasing. All-bolted column connections, as a novel structural connection technology, have attracted widespread attention due to their unique self-resetting capability and passive energy dissipation characteristics. However, existing all-bolted column connections on the market still have some shortcomings in structural design and performance.

[0003] The existing all-bolted column connection nodes mainly consist of the following parts:

[0004] (1) Column: As the main load-bearing component of the connection node, the column is usually made of high-strength steel and has good compressive and bending resistance.

[0005] (2) Connectors: Connectors are key components that connect columns to other structural components. They are usually made of steel plates or steel sections and are fixed to the columns by welding or bolting.

[0006] (3) Self-resetting mechanism: The self-resetting mechanism is the core component of the all-bolted column connection node, and is usually composed of preload springs, dampers, etc. Under the action of external forces such as earthquakes, the self-resetting mechanism can absorb some energy and restore the connection node to its original position through the restoring force of the spring.

[0007] (4) Energy dissipation elements: Energy dissipation elements are another important part of the connection node, usually composed of viscous dampers, metal yield energy dissipators, etc. They can undergo plastic deformation under external force, thereby dissipating energy and reducing the vibration response of the structure.

[0008] Although existing all-bolted column joints have achieved certain results in structural design and performance, they still have some obvious drawbacks:

[0009] (1) The self-resetting mechanism and energy-consuming components in the prior art usually adopt complex mechanical structures, which increases the difficulty of manufacturing and installation, and also increases the cost.

[0010] (2) The energy dissipation components in the prior art are usually viscous dampers or metal yield energy dissipators, etc. Their energy dissipation capacity is limited by material properties and structural size, making it difficult to meet the energy dissipation demand under a major earthquake.

[0011] (3) Components such as the preload spring in the self-resetting mechanism may become loose or fatigued during long-term use, resulting in a decrease or failure of the self-resetting ability.

[0012] (4) The connection nodes in the prior art are usually only applicable to specific types of structures and materials, and have poor adaptability to different materials and structures.

[0013] (5) Due to the complex structure and the fact that key components such as energy-consuming elements and self-resetting mechanisms are easily damaged or fail, regular inspection and maintenance are required, which increases maintenance costs. Summary of the Invention

[0014] The purpose of this invention is to provide an all-bolted column connection node to solve at least one of the technical problems existing in the prior art.

[0015] To solve the above-mentioned technical problems, the present invention provides an all-bolted column connection node, including a composite core column;

[0016] The combined core column includes a groove and a column;

[0017] The groove and the column are respectively welded to the ends of the first column and the second column that are connected to each other;

[0018] The size of the groove is the same as the size of the column, and the position of the groove corresponds to that of the column.

[0019] When the ends of the first column and the second column are connected, the column portion is inserted into the groove portion, which has a limiting effect in the horizontal direction.

[0020] Furthermore, the composite core is formed by cold bending of a thin steel plate.

[0021] Furthermore, the ends of the first column and the second column are respectively provided with insertion plate slots and insertion plates;

[0022] Damping rubber is provided on both sides of the insert plate.

[0023] Furthermore, the insert slot and the insert plate are connected by high-strength bolts.

[0024] Furthermore, it also includes ring-shaped clips;

[0025] The upper end of the ring-shaped card is fixedly connected to the first column.

[0026] The lower end of the ring-shaped clip is fixedly connected to the second column.

[0027] Preferably, the ring-shaped card is made of shape memory alloy.

[0028] Furthermore, the first column and the second column are respectively provided with an upper pressure plate and a lower pressure plate;

[0029] The upper end of the ring-shaped card is fixedly connected to the first column through the upper pressure plate;

[0030] The lower end of the annular clip is fixedly connected to the second column via the lower pressure plate.

[0031] Furthermore, the first column is also provided with a double-disc-shaped clip;

[0032] The upper end of the double-disc-shaped clip is fixedly connected to the first column, and the lower end is fixed to the second column by the lower pressure plate.

[0033] Preferably, the material of the dual-disc card is a shape memory alloy.

[0034] On the other hand, this application also discloses a building comprising a fully bolted column connection node.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects:

[0036] (1) This technical solution achieves a passive self-resetting function between the first column and the second column through the design of the combined core column. When the column is inserted into the slot, it not only provides horizontal limiting, but also, due to the characteristics of the structure itself, can cause the column to return to its original position after displacement or deformation, thus enhancing the stability and reliability of the structure.

[0037] (2) The design of the insert plate slot and insert plate, especially the damping rubber on both sides of the insert plate, can effectively absorb and disperse the energy generated by vibration, reduce the impact on the structure, and improve the overall seismic resistance and vibration reduction performance.

[0038] (3) High-strength bolts are used to connect the insert plate slot and the insert plate, which ensures the strength and stability of the connection node, increases the load-bearing capacity of the structure, and is suitable for various application scenarios that require high-strength connections.

[0039] (4) The ring-shaped and double-disc-shaped fasteners are made of shape memory alloy, which has excellent shape memory effect and superelasticity. When subjected to external force, they can deform and restore their original shape, further enhancing the structure's self-resetting ability and fatigue resistance.

[0040] (5) The components in this technical solution are reasonably designed, easy to install, and convenient for later maintenance and replacement. At the same time, the standardized connection method improves construction efficiency and project quality.

[0041] (6) The composite core column is formed by cold bending of thin steel plate, which not only reduces the structural weight, but also improves the utilization rate of materials and reduces costs. Attached Figure Description

Detailed Implementation

[0054] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] The present invention will be further explained below with reference to specific embodiments.

[0058] Example 1

[0059] like Figure 1-2 As shown, this embodiment provides an all-bolted column connection node, including a composite core column 1;

[0060] The combined core column 1 includes a groove 2 and a column 3;

[0061] The groove 2 and the column 3 are respectively welded to the ends of the first column 4 and the second column 5 that are connected to each other;

[0062] The size of the groove 2 is the same as the size of the column 3, and the position of the groove 2 corresponds to that of the column 3;

[0063] When the ends of the first column 4 and the second column 5 are connected, the column part 3 is inserted into the groove part 2, which has a limiting effect in the horizontal direction.

[0064] The composite core 1 is formed by cold bending of thin steel plate.

[0065] During assembly, the first column 4 and the second column 5 are coaxially aligned and close to each other. Since the column portion 3 corresponds in position to the groove portion 2, the column portion 3 gradually enters the groove portion 2. Because the dimensions of the column portion 3 and the groove portion 2 correspond, the column portion 3 will not wobble or shift horizontally after entering the groove portion 2.

[0066] Furthermore, the connection nodes of this application can be used for connections between steel columns, or for connections between steel columns and column bases.

[0067] like Figure 1-2 The following is a further embodiment of this application: the ends of the first column 4 and the second column 5 are respectively provided with a plate slot 6 and a plate 7.

[0068] Damping rubber 8 is provided on both sides of the insert plate 7.

[0069] The insert slot 6 and the insert plate 7 are connected by high-strength bolts 9.

[0070] When the connection node of this application encounters a horizontally transmitted seismic wave, the first column 4 and the second column 5 will undergo relative movement in both the horizontal and vertical directions. The damping rubber 8 can provide structural self-resetting capability while dissipating system energy and reducing structural damage.

[0071] like Figure 1-3 The illustration shows a further embodiment of this application, which also includes a ring-shaped card 10;

[0072] The upper end of the ring-shaped fastener 10 is fixedly connected to the first column 4;

[0073] The lower end of the ring-shaped clip 10 is fixedly connected to the second column 5.

[0074] The ring-shaped card 10 is made of shape memory alloy.

[0075] The first column 4 and the second column 5 are respectively provided with an upper pressure plate 11 and a lower pressure plate 12;

[0076] The upper end of the ring-shaped card is fixedly connected to the first column 4 via the upper pressure plate 11;

[0077] The lower end of the annular clip is fixedly connected to the second column 5 via the lower pressure plate 12.

[0078] The first column 4 is also provided with a double-disc-shaped clip 13;

[0079] The upper end of the double-disc-shaped clip 13 is fixedly connected to the first column 4, and the lower end is fixed to the second column 5 by the lower pressure plate 12.

[0080] The dual-disc card 13 is made of shape memory alloy.

[0081] To further enhance the self-resetting capability of the connection node in this application, an annular locking element 10 and a double-disc locking element 13 are also provided on the connection node. Unlike the damping rubber 8, the annular locking element 10 and the double-disc locking element 13 are mainly designed to handle the situation where the first column 4 and the second column 5 separate axially, at which time the annular locking element 10 and the double-disc locking element will be stretched in the vertical direction. Since the annular locking element 10 and the double-disc locking element 13 in this embodiment are made of shape memory alloy, they can generate a restoring force when stretched in the vertical direction.

[0082] By adopting the above technical solution, the present invention has the following beneficial effects:

[0083] (1) This technical solution achieves a passive self-resetting function between the first column 4 and the second column 5 through the design of the combined core column 1. When the column 3 is inserted into the slot 2, it not only provides horizontal limiting, but also, due to the characteristics of the structure itself, can cause the column to return to its original position after displacement or deformation, thus enhancing the stability and reliability of the structure.

[0084] (2) The design of the insert plate groove 6 and the insert plate 7, especially the damping rubber 8 set on both sides of the insert plate 7, can effectively absorb and disperse the energy generated by vibration, reduce the impact on the structure, and improve the overall seismic resistance and vibration reduction performance.

[0085] (3) High-strength bolts 9 are used to connect the insert plate slot 6 and the insert plate 7, which ensures the strength and stability of the connection node, increases the load-bearing capacity of the structure, and is suitable for various application scenarios that require high-strength connections.

[0086] (4) The ring-shaped clip 10 and the double-disc clip 13 are made of shape memory alloy, which has excellent shape memory effect and superelasticity. When subjected to external force, they can deform and restore their original shape, further enhancing the self-resetting ability and fatigue resistance of the structure.

[0087] (5) The components in this technical solution are reasonably designed, easy to install, and convenient for later maintenance and replacement. At the same time, the standardized connection method improves construction efficiency and project quality.

[0088] (6) The composite core column 1 is formed by cold bending of thin steel plate, which not only reduces the structural weight, but also improves the utilization rate of materials and reduces costs.

[0089] Example 2

[0090] like Figure 4-9 This application also discloses a building with all-bolted column connection nodes. The building contains a steel beam stable connection structure, including a main connecting horizontal support frame 110, a longitudinal beam positioning frame 210, and a cylinder connector 220. The main connecting horizontal support frame 110 is provided with a main connecting vertical support frame 120 on each side. A transverse positioning sleeve 130 and an adjusting outer frame 140 are installed on the main connecting vertical support frame 120. The transverse positioning sleeve 130 is located at the center line of the main connecting vertical support frame 120, and the adjusting outer frame 140 is respectively located on the upper and lower sides of the main connecting vertical support frame 120. An outer support connector 150 is installed on the adjusting outer frame 140. The outer support connector 150 is slidably installed on the adjusting outer frame 140, and the longitudinal beam positioning frame 210 is fixedly installed on the corresponding outer support connector 150.

[0091] The barrel connector 220 includes a transverse beam positioning barrel 250 and an outer barrel clamp 230 disposed on the outer wall of the transverse beam positioning barrel 250. The transverse beam positioning barrel 250 is inserted into the transverse positioning sleeve 130 and the outer barrel clamp 230 is fixedly installed with the transverse positioning sleeve 130. The outer wall of the transverse beam positioning barrel 250 is also provided with an outer barrel connecting bolt 240. The frame edge of the longitudinal beam positioning frame 210 is provided with an outer frame connecting bolt 260. The outer barrel connecting bolt 240 and the outer frame connecting bolt 260 are fixedly connected.

[0092] This embodiment is used for the positioning and connection of multiple longitudinal and transverse steel beams. The main connecting transverse support frame 110 and the main connecting vertical support frame 120 are the main supporting structures. The machine barrel connector 220 is sleeved and fixed on the transverse steel beam, while the longitudinal steel beams that intersect with the transverse steel beam are fixed and positioned by the longitudinal beam positioning frame 210. An opening is provided at the center line of the frame of the main connecting vertical support frame 120, and the transverse positioning sleeve 130 is set at the opening. The main body of the machine barrel connector 220 is the transverse beam positioning machine barrel 250. The transverse beam positioning machine barrel 250 is stably fixed in the transverse positioning sleeve 130 by the outer cylinder hoop 230 to ensure the reliability of the fixing structure itself. The transverse steel beam is installed inside the transverse beam positioning machine barrels 250 on the left and right sides, while the longitudinal steel beams that are supported above and below the transverse steel beam are positioned inside the longitudinal beam positioning frame 210.

[0093] In actual building structures, the longitudinal steel beams erected on the upper and lower sides of the transverse steel beams may not maintain symmetrical position coordinates. Therefore, in this embodiment, an adjusting outer frame 140 is also provided on the upper and lower sides of the transverse positioning sleeve 130 to adjust the working position of the outer support connector 150 by a small margin, that is, to adjust the working position of the longitudinal beam positioning frame 210 used to position the longitudinal steel beam. After the adjustment is completed, the outer support connector 150 is locked and fixed on the adjusting outer frame 140, thereby adapting to the coordinate differences of the longitudinal and transverse steel beams in different building areas.

[0094] To further improve the overall stability, this embodiment also includes an outer cylinder connecting bolt 240 and an outer frame connecting bolt 260. The outer cylinder connecting bolt 240 and the outer frame connecting bolt 260 are used to reconnect the longitudinal beam positioning frame 210 and the machine cylinder connecting piece 220, thereby increasing the connection points of the transverse steel beam and the longitudinal steel beam on the outside of the main connecting vertical support frame 120, thus improving the overall stability coefficient.

[0095] This embodiment can effectively ensure the staggered erection of multiple sets of longitudinal and transverse steel beams. A stable frame connection structure is set at the staggered erection position to form a stable support from the inside out, thereby forming an integral and stable connection range.

[0096] In one embodiment, see Figure 5 and Figure 6This embodiment is a further optimization of the above embodiment. Based on it, the installation structure of the adjusting outer frame 140 and the main connecting vertical support frame 120 is designed as follows:

[0097] The main connecting vertical support frame 120 includes a frame base block 310, a vertical support base plate 320 installed on the side edge of the frame base block 310, and an outer support rail 330 installed on the vertical support base plate 320. The adjustable outer frame 140 includes a base mounting plate 410, an adjustable base 420 disposed on the base mounting plate 410, and an adjustable rail 430 installed on the adjustable base 420. The outer support connector 150 includes a sliding base plate 450, a side support plate frame 460 disposed on the sliding base plate 450, and a fixed plate surface 470 installed on the side support plate frame 460. An adjusting slider 440 is also provided on the mounting surface of the sliding base plate 450, and the adjusting slider 440 is slidably mounted on the adjusting rail 430; the base mounting plate 410 is fixedly mounted on the vertical support base plate 320, and the adjusting base 420 is locked onto the outer railing 330 by a secondary fixing bolt 480; the longitudinal beam positioning frame 210 is welded and fixed to the plate surface of the fixed plate 470.

[0098] The frame base block 310 is fixedly installed at both ends of the main connecting horizontal support frame 110, and the vertical support base plate 320 is the main body of the main connecting vertical support frame 120, so that the main connecting horizontal support frame 110 and the main connecting vertical support frame 120 are combined into a stable support structure. The adjustment outer frame 140 and the main connecting vertical support frame 120 are fixed in a double manner. On the one hand, the base mounting plate 410 and the adjustment base 420 are integrally welded, and the two plates of the base mounting plate 410 and the vertical support base plate 320 are attached to each other to form a fixed installation, forming a fixed installation between the plates. On the other hand, the adjustment base 420 itself is also locked to the outer support 330 through the secondary fixing bolt 480, forming a double fixing structure to ensure the stability of the installation of the adjustment outer frame 140.

[0099] The longitudinal beam positioning frame 210 is welded and fixed to the plate surface 470. The fixed plate surface 470, the side support plate frame 460 and the sliding base plate 450 are an integrated plate structure. The positioning position of the longitudinal beam positioning frame 210 can be adjusted by adjusting the slider 440 along the adjustment track 430, so that the longitudinal beam positioning frame 210 can position the longitudinal steel beam in a suitable position.

[0100] In one embodiment, see Figure 4 and Figure 7 The steel beams used in daily life are generally long steel bars with an I-shaped cross-section. Therefore, the specific implementation structure of the longitudinal beam positioning frame 210 is designed as follows in this embodiment:

[0101] The longitudinal beam positioning frame 210 includes an outer support frame 510 and reinforcing frame strips 520 disposed on the frame of the outer support frame 510. An inner protrusion 530 is disposed along the inner edge of the frame of the outer support frame 510. The inner protrusion 530 arches inward and has an abutment against the inner edge 540. In this embodiment, the longitudinal beam positioning frame 210 is designed as a support structure of a frame body. The outer support frame 510 is the main support frame, and the reinforcing frame strips 520 are disposed in the outer structure of the frame of the outer support frame 510, forming a stable outer support structure that provides auxiliary stabilization. The inner wall of the frame of the outer support frame 510 is provided with inner protrusions 530. The inner protrusions 530 on both sides arch inward, forming an inward arching trend. The middle position of the inner protrusion 530 has an abutment against the inner edge 540. This inward arching structure supports the middle area of ​​the side of the I-shaped steel beam, maintaining the stability of the steel beam.

[0102] In one embodiment, see Figure 5 and Figure 8 Based on the above embodiments, the specific implementation structure of the lateral positioning sleeve 130 is designed as follows:

[0103] The transverse positioning sleeve 130 includes a steel beam positioning sleeve 340 installed on the vertical support base plate 320. An inner fixing rod 350 is provided on the hoop of the steel beam positioning sleeve 340. A connecting sleeve 360 ​​is provided on the side edge of the steel beam positioning sleeve 340. A positioning hoop 370 is installed on the connecting sleeve 360. A connecting strip 380 is provided on the side edge of the positioning hoop 370. The transverse beam positioning cylinder 250 passes through the steel beam positioning sleeve 340 along the connecting sleeve 360 ​​and is fixed by the inner fixing rod 350.

[0104] The transverse positioning sleeve 130 is a cylindrical assembly structure. The transverse beam positioning sleeve 250 passes through the steel beam positioning sleeve 340 along the connecting sleeve 360, thereby completing the mutual assembly. It is then fixed by the insertion of the inner fixing rod 350. The transverse beam positioning sleeve 250 is a positioning structure for the transverse steel beam. The transverse steel beam passes through the transverse beam positioning sleeve 250 at one end, through the steel beam positioning sleeve 340, and then through the steel beam positioning sleeve 340 at the other end to the transverse beam positioning sleeve 250 at the other end, thus completing the fixation of the transverse steel beam. The inner cavity of the transverse beam positioning sleeve 250 can also accommodate the I-shaped steel beam structure, and an inner insertion interval is designed to match it.

[0105] To further improve the support stability of the transverse beam positioning cylinder 250, please refer to... Figure 5 and Figure 8This embodiment also designs the following structure: the outer cylinder hoop 230 includes a cylinder edge frame strip 610 and an outer fixing hoop 620. The cylinder edge frame strip 610 and the outer fixing hoop 620 are combined to form a frame structure. The cylinder edge frame strip 610 is fixed to the periphery of the transverse beam positioning machine cylinder 250. The outer fixing hoop 620 is attached to the outer wall of the transverse beam positioning machine cylinder 250 and inserted into the connecting sleeve 360. A reinforcing connecting strip 630 is installed on the side edge of the cylinder edge frame strip 610. The reinforcing connecting strip 630 is attached to the outer wall of the transverse beam positioning machine cylinder 250 and connected to the connecting strip 380.

[0106] The outer cylinder hoop 230 is a frame structure set around the transverse beam positioning machine cylinder 250. It is a combination of the cylinder edge frame strip 610 and the outer fixing hoop 620, and is hooped around the transverse beam positioning machine cylinder 250. The side edge of the connecting sleeve 360 ​​is also provided with an insertion end. The outer fixing hoop 620 is connected to the connecting sleeve 360 ​​by insertion, and then connected to the connecting strip 380 by the reinforcing connecting strip 630. This strengthens the connection around the transverse beam positioning machine cylinder 250, so that the hoops at both ends of the transverse beam positioning machine cylinder 250, namely the positioning hoop 370 and the cylinder edge frame strip 610, form a stable external support structure, thereby improving the support of the transverse steel beam and maintaining the stable connection of the steel beam.

[0107] In one embodiment, see Figure 4 , Figure 8 and Figure 9 Based on the above embodiments, the specific implementation structure of the lateral positioning sleeve 130 is designed as follows:

[0108] The outer end of the transverse beam positioning cylinder 250 is provided with a steel beam exposed opening 640. The steel beam exposed opening 640 is provided with outer wing frames 650 facing the upper and lower sides. The outer cylinder connecting bolt 240 includes a connecting frame surface 710, an adjustment groove 720 provided on the connecting frame surface 710, and a connecting adjustment block 740 installed on the adjustment groove 720. The outer frame connecting bolt 260 includes a locking bolt 560 installed on the reinforcing frame strip 520. The connecting adjustment block 740 is externally connected to a parallel bolt 730, which is inserted into the locking bolt 560 and fixedly installed by a locking bolt 550.

[0109] In this embodiment, the outer end of the transverse beam positioning machine cylinder 250 is designed as an "eight"-shaped outer shell. The outer wing frame 650 extends towards the longitudinal beam positioning frames 210 on the upper and lower sides. A connecting frame surface 710 is provided on the outer shell of the outer cylinder connecting bolt 240. The connecting adjustment block 740 is installed on the adjusting groove 720. The working position of the connecting adjustment block 740 is finely adjusted so that the parallel bolt 730 is accurately inserted into the locking bolt 560. The parallel bolt 730 is then locked and fixed by the locking bolt 550. At the same time, the fixing bolt on the locking connecting adjustment block 740 is fixedly installed, thus completing the fixed installation of the outer wing frame 650 and the longitudinal beam positioning frames 210 on the upper and lower wings.

[0110] In this way, based on the main connecting vertical support frame 120 as the connecting structure of the horizontal and vertical steel beams, the horizontal beam positioning cylinder 250 and the vertical beam positioning frame 210 used to fix the horizontal and vertical steel beams are then connected to improve the stability coefficient of the overall connection area. Even with the structure of multiple intersecting steel beams, sufficient stability can be guaranteed to ensure the support strength of the overall building structure.

[0111] Compared with the prior art, the beneficial effects of the present invention are:

[0112] (1) The present invention is used for positioning and connecting multiple steel beams at the intersection. The main connecting horizontal support frame and the main connecting vertical support frame are the main supporting structures. The machine barrel connector is sleeved and fixed on the horizontal steel beam, while the longitudinal steel beams that intersect with the horizontal steel beam are fixed and positioned by the longitudinal beam positioning frame. An opening is provided at the center line of the main connecting vertical support frame, and the horizontal positioning sleeve is set at the opening. The main body of the machine barrel connector is the horizontal beam positioning machine barrel. The horizontal beam positioning machine barrel is stably fixed in the horizontal positioning sleeve by the outer cylinder hoop to ensure the reliability of the fixing structure itself. The entire horizontal steel beam is installed inside the horizontal beam positioning machine barrels on the left and right sides, while the longitudinal steel beams that are supported above and below the horizontal steel beams are positioned inside the longitudinal beam positioning frame.

[0113] (2) The present invention also provides an adjustment frame on the upper and lower sides of the transverse positioning sleeve to adjust the working position of the external support connector by a small range, that is, to adjust the working position of the longitudinal beam positioning frame used to position the longitudinal steel beam. After the adjustment is completed, the external support connector is locked and fixed on the adjustment frame, so as to adapt to the coordinate differences of the longitudinal steel beam and the transverse steel beam in different building areas.

[0114] (3) The present invention is also provided with an outer cylinder connecting bolt and an outer frame connecting bolt, and the longitudinal beam positioning frame and the machine cylinder connecting piece are connected again by the outer cylinder connecting bolt and the outer frame connecting bolt, thereby increasing the connection points of the transverse steel beam and the longitudinal steel beam on the outside of the main connecting vertical support frame, thus improving the overall stability coefficient.

[0115] This invention can effectively ensure the staggered erection of multiple sets of longitudinal and transverse steel beams. A stable frame connection structure is set at the staggered erection position to form a stable support from the inside out, thereby forming an integral and stable connection range.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
