Detailed Description
The present application will be described in detail with reference to the accompanying drawings.
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Example 1
As shown in fig. 1 to 4, the rapid installation node structure for the super high-rise complex steel structure according to the present application comprises a connection assembly 1 and a positioning component 2, wherein the connection assembly 1 is used for connecting a steel beam member 3 and a bracket of a steel column member 4 so as to form hinged connection therebetween, the positioning component 2 is arranged on the steel beam member 3 or the bracket of the steel column member 4, and the positioning component 2 is positioned on an assembly moving path of the steel beam member 3, so that when the steel beam member 3 moves to an installation position, the positioning component 2 is abutted against the bracket of the steel column member 4 or the steel beam member 3.
Currently, in steel structure construction, the connection manner between the steel beam member 3 and the steel column member 4 is generally as follows: bracket for connecting with the steel beam member 3 is welded on the steel column member 4 in advance, a connecting plate is arranged at the position where the bracket of the steel column member 4 is connected with the steel beam member 3, a bolt hole is arranged on the connecting plate, preliminary positioning connection is formed between the steel beam member 3 and the bracket of the steel column member 4 through the cooperation of the connecting plate and the bolt, and then welding treatment is carried out, so that rigid connection is formed between the steel beam member 3 and the steel column member 4. The bolt-welding mixed connection is installed and positioned by bolts, and then the welding treatment is performed, so that the operation is convenient, and the application is common. However, the installation of the steel beam member 3 is usually assisted by a tower crane, and the shaking of the steel beam is particularly obvious in the high-altitude operation process, so that a great deal of time is required to be consumed in the preliminary positioning connection process of the steel beam member 3 and the bracket of the steel column member 4, and the whole progress of the engineering is seriously delayed. Based on this, in this embodiment, the inventor sets up the locating component 2 on the basis of the original installation structure of the steel beam member 3, so as to reduce the deviation generated in the butt joint process of the steel beam member 3 and the bracket of the steel column member, thereby improving the installation efficiency of the steel beam member 3 and ensuring the overall progress of the engineering.
In the above-described embodiment, the positioning member 2 is further configured to level a deviation generated in the vertical direction of the connection portion due to vertical shaking when the steel beam member 3 is installed.
In the hoisting process of the steel beam structure, the vertical shaking displacement and the horizontal shaking displacement mainly exist, and two factors mainly influence the installation of the steel beam component 3. In actual construction, the inventor found that only any one of the above factors affecting the installation of the steel beam structure is controlled to greatly improve the installation efficiency of the steel beam member 3, so that the inventor sets the positioning part 2 for leveling the deviation generated in the longitudinal direction of the connection part due to the up-and-down shaking when the steel beam member 3 is installed in this embodiment. On the one hand, can simplify this novel overall structure, reduction in production's manufacturing cost, on the other hand, locating part 2 in this embodiment also can cooperate with the dead weight of girder steel component 3 itself, improves the efficiency that adopts this novel locating part 2 leveling girder steel component 3 to rock from top to bottom when installing to girder steel component 3's installation effectiveness has further been improved.
As a preferred embodiment, further, based on the above manner, the positioning component 2 includes a horse board 5, one side of the horse board 5 is welded on the top surface of the steel beam member 3, and the other side is used for being lapped on the top surface of the bracket of the steel column member 4. The horse plate 5 is adopted as the positioning component 2, so that the integral structure of the application is simplified, and the production and manufacturing cost is reduced; meanwhile, in actual use, the adjusting mode of the horse plate 5 is simple and quick, and the installation efficiency of the steel beam member 3 is further improved.
As a preferred embodiment, further, in the above-described mode, the welding length between the horse board 5 and the steel beam member 3 is 5cm or more. By adopting the structure, the welding quality of the horse board 5 can be improved, and the occurrence of safety accidents caused by the unwelded horse board 5 in the using process is avoided.
As a preferred embodiment, in the above mode, further, the overlapping length between the horse board 5 and the bracket of the steel column member 4 is set to be less than or equal to the welding length between the horse board 5 and the steel beam member 3. By adopting the structural arrangement, on one hand, the influence on the adjustment efficiency in the installation process of the steel beam member 3 due to the overlong overlapping length of the horse plate 5 and the bracket of the steel column member 4 is avoided; on the other hand, the steel beam member 3 is prevented from colliding in the process of adjusting the installation position, so that the horse plate 5 is deformed, the connection between the horse plate 5 and the steel beam member 3 is caused to be unwelded, and potential safety hazards are brought to construction.
As a preferred embodiment, based on the above mode, further, the bottom of the horse board 5 lapped on one side of the steel column member 4 bracket is provided with a plurality of saw teeth 10, and when the end part of the saw teeth 10 is abutted on the convex part on the surface of the steel column member 4 bracket, deformation can be generated, so that vertical deviation between the steel beam member 3 and the steel column member 4 bracket after the horse board 5 is lapped on the steel column member 4 bracket is reduced.
In this embodiment, the inventor considers that, in the actual installation process of the steel beam member 3, since the surface of the bracket of the steel column member 4 cannot be absolutely leveled, after the saddle 5 is lapped on the surface of the bracket of the steel column member 4, a certain slight deviation exists between the steel beam member 3 and the steel column member 4 in the vertical direction, which affects the installation efficiency of the subsequent bolts. Based on this, in this embodiment, the bottom of the horse board 5 overlapping the steel column member 4 bracket is provided with a plurality of saw teeth 10, and when the end of the saw teeth 10 abuts against the raised portion on the surface of the steel column member 4 bracket, deformation can be generated, so that the vertical deviation between the steel beam member 3 and the steel column member 4 bracket after the horse board 5 is overlapped on the steel column member 4 bracket is reduced. Meanwhile, after the saw teeth 10 are arranged, the contact area between the horse plate 5 and the bracket of the steel column member 4 is reduced, the probability that the bottom surface of the horse plate 5 contacts with the surface of the bracket of the steel column member 4 is reduced, and therefore the installation efficiency of the steel beam member 3 is further improved.
As a preferred embodiment, based on the above manner, the plurality of saw teeth 10 are further divided into a first saw tooth set 11 and a second saw tooth set 12 along the extending direction of the horse board 5 to the bracket of the steel column member 4, the first saw tooth set 11 and the second saw tooth set 12 are parallel to each other, and a plurality of saw teeth 10 in the first saw tooth set 11 and a plurality of saw teeth 10 in the second saw tooth set 12 are correspondingly arranged.
By adopting the structure, the probability that the end parts of the saw teeth 10 are contacted with the surface protrusions of the steel column member 4 is further reduced; the simultaneous division of two sets of serrations also allows the ends of the serrations 10 to be easily deformed, thereby further improving the installation efficiency of the steel beam member 3.
As a preferred embodiment, further, on the basis of the above mode, the tooth height of the plurality of saw teeth 10 is set to 1/5 to 1/6 of the width of the horse board 5. By adopting the structural arrangement, the integral strength of the saw teeth 10 is ensured, and the collision generated in the transportation process or the installation process is avoided, so that the saw teeth 10 are integrally deformed, and the leveling installation of the steel beam member 3 is affected.
As a preferred embodiment, in the above manner, further, the saddle 5 is disposed on one side of the longitudinal central axis of the top surface of the steel beam member 3.
In this embodiment, the inventor considers that after the rigid beam member and the steel column member 4 are initially connected, the steel beam member 3 and the bracket of the steel column member 4 need to be welded, so that the welding seam between the steel beam member 3 and the bracket of the steel column member 4 is more consistent, and weak points formed by welding the two are reduced, and in this embodiment, the inventor sets the horse board 5 on one side of the longitudinal central axis of the top surface of the steel beam member 3. Therefore, a welding seam which is as long as possible can be formed between the bracket of the steel beam member 3 and the bracket of the steel column member 4, and the overall consistency of the welding seam is ensured, so that the connection stability between the steel beam member 3 and the steel column member 4 is further improved.
As a preferred embodiment, based on the above mode, further, a recess 6 is provided on the saddle 5, and the position of the recess 6 corresponds to the position of the connecting seam formed by the bracket of the steel beam member 3 and the steel column member 4. By adopting the structural arrangement, the connecting seam of the shielding position of the saddle 5 can be welded, and the connection stability between the steel beam member 3 and the steel column member 4 is further improved.
Example 2

With the structure, the operation of workers is facilitated, and the installation efficiency of the steel beam member 3 is further improved; meanwhile, after the connecting assemblies 1 are symmetrically arranged on the opposite sides of the horse plate 5, the connecting force distribution formed between the steel beam member 3 and the bracket of the steel column member 4 is more even, so that the connecting stability between the steel beam member 3 and the steel column member 4 is further improved.
As a preferred embodiment, based on the above mode, the connecting assembly 1 further comprises two clamping plates 7, and the ear plates 8 welded on the end of the steel beam member 3 and the bracket end of the steel column member 4 respectively, the ear plates 8 and the clamping plates 7 are provided with bolt holes, and the two clamping plates 7 connect the ear plates 8 on the steel beam member 3 and the ear plates 8 on the steel column member 4 into a whole under the cooperation of the mounting bolts 9.
When the embodiment is used, after the horse plate 5 is lapped on the bracket of the steel column member 4, the abutting relation between the steel beam member 3 and the bracket of the steel column member 4 is adjusted, so that the connecting surfaces of the steel beam member 3 and the bracket of the steel column member 4 are completely overlapped, the ear plate 8 is connected by bolts through the two connecting plates, the steel beam member 3 and the bracket of the steel column member 4 form stable hinged connection, thereby effectively preventing the members from sliding in the vertical and horizontal directions, enabling the members to be easily adjusted due to deviation, and enabling the tower crane to be unhooked for next member installation.

Example 3
As shown in fig. 1 to 5, the method for installing a steel structure according to the present application comprises the steps of:
A. hoisting the steel column member 4: and hoisting the steel column member 4 according to the design drawing to form a preliminary supporting structure.
B. Hoisting the steel beam member 3: and C, after the steel column member 4 in the step A is lifted, lifting the steel beam member 3, and adopting the rapid installation node structure to form hinged connection between the steel beam member 3 and the steel column member 4.
C. Welding: the connection part between the steel beam member 3 and the steel column member 4 is welded to form a rigid connection.
By adopting the construction method, on the premise of ensuring stable connection between the steel column member 4 and the steel beam member 3, the rapid installation node structure is matched with the construction method, so that deviation generated in the butt joint process of the steel beam member 3 and the steel column member is reduced, and the installation efficiency of the steel beam member 3 is improved.
In the above mode, the method further divides a running water construction area before the step A steel column member 4 is hoisted and the step B steel beam member is hoisted, so that the requirements of cross construction of various kinds of works are met.
As a preferred embodiment, further, when the steel column member 4 is hoisted, a hoisting point is arranged at the top of the steel column member 4, and a temporary connecting plate is welded at the top of the steel column member 4 as a hoisting connection point.
Specifically, the steel column is hoisted by a single machine of a field tower crane, and a special shoulder pole lifting lug is a hoisting hole on a connecting plate at the upper end of the column. The root of the steel column is padded tightly during lifting, so that the steel column is gradually straightened through lifting and amplitude changing of the lifting hook and rotation of the lifting arm under the condition that the root is not separated from the ground, and then the steel column is lifted continuously after the steel column stops shaking. In order to make the hoisting stable, two white palm ropes should be tied at the upper end of the steel column for traction.
Before the steel column is lifted, the temporary steel cat ladder is bound on the steel column. After the steel column is hoisted in place, the fixing plate is temporarily designed, and the fixing plate is temporarily fixed by using a large hexagonal high-strength bolt. Before fixing, parameters such as elevation, verticality, offset, torsion and the like of the steel column are adjusted within the standard requirement range. The large hexagonal high-strength bolt can be fully fastened to be unhooked at the top of the column.
After the steel column is in place, the relative elevation control method is adopted according to the sequence of adjusting elevation, then adjusting torsion and finally adjusting verticality, and the steel column is accurately corrected by means of tools such as a tower crane, a steel wedge, a base plate, a crowbar, a jack and the like. No overall adjustment is required after the frame is formed.
When the elevation of the steel column is adjusted, the lifting and falling of the lifting hook of the tower crane and the crowbar are utilized to stir and adjust the gap between the upper column and the lower column until the gap meets the requirement, and steel wedges are driven into the gap between the upper fixing plate and the lower fixing plate. The torsion adjusting method is to add backing plates on different sides of the upper and lower fixing plates, and then clamp the fixing plates to achieve the purpose of correcting torsion deviation.
The verticality is adjusted through the jack and the steel wedge, the iron wedge is hammered or the jack is slightly jacked on the same side of the deflection of the steel column, at the same time, at least three wind-collecting ropes are tensioned on the top of the column, and the verticality of the steel column can be adjusted by tightening the wind-collecting ropes.
As a preferred embodiment, further, each steel column is required to be calibrated after installation in the above manner. After the temporary fixation of the steel column member 4 is completed in this embodiment, the deviation in verticality, axis deviation, and elevation deviation thereof are corrected by a jack, a chain block, a wedge, and the like. Thereby avoiding the subsequent problem caused by the installation quality of the steel column member 4, resulting in repeated construction and affecting the overall progress of the engineering.
Further, in the step B, the steel beam member 3 should be cleaned of dirt and rust on the surface of the steel column member 4 before being lifted. By adopting the construction method, the bulges on the bracket surfaces of the steel column members 4 can be reduced as much as possible, the deviation of the steel beam members 3 and the steel column members 4 during butt joint installation is reduced, and the installation efficiency of the steel beam members 3 is improved.
In the preferred embodiment, further, a dedicated lifting point needs to be set for lifting the steel beam member 3, and the lug plate 8 is prohibited from being used as the lifting point of the steel beam member 3. By adopting the construction method, the problem that the bolts cannot be normally installed due to deformation of the lug plates 8 is avoided, and the installation efficiency of the steel beam member 3 is affected.
As a preferred embodiment, on the basis of the above mode, when the steel beam member 3 is hung into a predetermined installation position, the steel beam member 3 is integrally guaranteed to be in a horizontal state, and the horse plate 5 on the steel beam member 3 is prevented from being knocked. By adopting the method, the phenomenon that the horse plate 5 is deformed or even is unwelded in the installation process, and the installation efficiency of the steel beam member 3 is affected is effectively avoided.
In a preferred embodiment, in addition to the above-described embodiment, the lateral deviation between the steel beam member 3 and the bracket of the steel column member 4 is further adjusted in a state where the steel beam member 3 is lifted up as a whole. In this way, on the one hand, the effect of the deformation of the whole of the saw tooth 10 affecting the leveling is avoided. On the other hand, the connection and the desoldering between the horse plate 5 and the steel beam member 3 are avoided, and potential safety hazards are generated.
In the preferred embodiment, after the steel beam member 3 is suspended at the predetermined mounting position, the steel beam member is temporarily fixed by using a normal bolt, and the steel beam member is prevented from being directly fixed by using a high-strength bolt. By adopting the method, the damage of the high-strength bolt in the initial structure of the connection of the steel beam member 3 and the steel column member 4 is avoided, and the connection stability between the steel beam member 3 and the steel column member 4 is influenced.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
