Description

Technical Field

[0001] This invention relates to the field of building curtain wall installation technology, specifically to a connection structure for anti-displacement curtain wall embedded parts and its construction method for installing building curtain walls. Background Technology

[0002] As the external envelope of modern buildings, the installation accuracy and structural safety of building curtain walls are highly dependent on the quality of the embedded parts. The embedded parts are key load-bearing components that connect the keel to the main concrete structure. The planar position, elevation, verticality and flatness of the embedded parts directly determine the installation accuracy, load-bearing reliability and facade forming effect of the curtain wall.

[0003] The current method for pre-embedded components in curtain walls typically involves construction workers roughly marking the location based on the structural axis, temporarily fixing the pre-embedded components to the main structural steel bars by tying or spot welding, and then closing the formwork and pouring concrete. This construction method has the following drawbacks in actual projects:

[0004] 1. Uncontrollable positioning accuracy: Relying on manual visual inspection and simple tools for line laying, it is easily affected by the operator's skills and the on-site environment, resulting in large cumulative errors. The deviation of the plane position and elevation is likely to exceed the allowable range of the specification.

[0005] 2. Easily disturbed and misaligned during pouring: The embedded parts are only flexibly connected to the steel bars. The lateral pressure and impact force generated by concrete pouring and vibration can easily cause the embedded parts to shift, tilt, float or sink, resulting in misalignment, verticality and flatness that do not meet the design and specification requirements.

[0006] 3. Damage caused by fixing methods: Spot welding can easily burn the main reinforcement bars and damage the protective layer of the reinforcement bars, affecting the load-bearing performance of the main structure; binding fixing is not strong enough and cannot resist the disturbance of pouring.

[0007] 4. Difficulty in correcting deviations: After the mold is sealed, the position of the embedded parts cannot be checked and fine-tuned. The deviation problem is only exposed after the mold is removed. Only remedial measures such as post-embedded plates, lengthening adapters, and welding reinforcement can be taken, which increases costs and construction time, reduces the reliability of the nodes under stress, and leaves safety hazards.

[0008] Chinese patent CN117145114A discloses a pre-embedded component connection structure and its curtain wall, including a support assembly installed on a reinforcing cage; an adjustment assembly installed on the support assembly; and a load-bearing assembly for mounting the pre-embedded component installed on the adjustment assembly. This invention effectively improves the installation effect of the pre-embedded component by installing the support assembly inside the reinforcing cage, then installing the T-bolts of the pre-embedded component onto the load-bearing assembly, and using the adjustment assembly to adjust the position of the T-bolts of the pre-embedded component via the load-bearing assembly.

[0009] The aforementioned embedded component connection structure is installed on the reinforcing cage, with multiple reinforcing bars accommodated by two receiving slots at both ends of the second strip. This necessitates a special design for the reinforcing cage based on the connection structure. Furthermore, if the connection structure is installed on the stirrups of the reinforcing cage, it may cause localized bending of the stirrups, cracking of the welds, leading to ellipticity, twisting, or even bending of the cage, affecting the overall structure of the reinforcing cage. If it is installed on the vertical reinforcing bars of the reinforcing cage, the connection structure may become misaligned during concrete pouring, affecting the accurate embedding of the embedded component. Moreover, the connection accuracy of the connection structure is affected by the reinforcing cage and its own structure, making it difficult to meet the requirements for accurate embedding of the embedded component. Summary of the Invention

[0010] The present invention aims to overcome the defects in the prior art and provide a connection structure for anti-displacement curtain wall embedded parts for the installation of building curtain walls that is precisely adjustable, securely locked, and safe and reliable in construction, as well as its construction method.

[0011] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a connection structure for an anti-displacement curtain wall embedded component for installing a building curtain wall, comprising a building foundation and a vertical component connected to the building foundation, wherein the bottom of the vertical component is embedded within the building foundation; the vertical component contains a steel cage and a structural column for supporting the vertical component, the structural column being located in the middle of the steel cage, and the bottom of the structural column being embedded within the building foundation; the vertical component contains a curtain wall embedded component for installing the building curtain wall, and the structural column is provided with a connecting component connected to the curtain wall embedded component; the connecting component includes a positioning steel bar connected to the anchor rod side of the curtain wall embedded component and a fixing connector for accurately fixing the positioning steel bar, the positioning steel bar passing through the structural column, and the fixing connector being fixedly connected to the structural column.

[0012] As a preferred embodiment of the present invention, the structural column includes a plurality of vertically arranged supporting steel bars and a plurality of annular stirrups connected to the plurality of supporting steel bars, and the fixing connector is welded and fixed to the supporting steel bars.

[0013] As a preferred embodiment of the present invention, a plurality of supporting steel bars are arranged in an array, a positioning steel bar passes through the plurality of supporting steel bars arranged in the array, and a fixing connector includes a first fixing steel bar and a second fixing steel bar for connecting the positioning steel bar and the supporting steel bars.

[0014] As a preferred embodiment of the present invention, the first fixed reinforcing bar and the second fixed reinforcing bar are located on opposite sides of a plurality of supporting reinforcing bars arranged in an array, and the second fixed reinforcing bar is located between the first fixed reinforcing bar and the curtain wall embedded part. The first fixed reinforcing bar is welded to the upper and lower sides of the positioning reinforcing bar, and the second fixed reinforcing bar is welded to the bottom of the positioning reinforcing bar.

[0015] In a preferred embodiment of the present invention, the first fixing steel bar and the second fixing steel bar are arranged in parallel, and both the first fixing steel bar and the second fixing steel bar are arranged alternately with the positioning steel bar.

[0016] As a preferred embodiment of the present invention, the curtain wall embedded part is connected to two positioning steel bars, which are symmetrical about the center of the curtain wall embedded part.

[0017] As a preferred embodiment of the present invention, the plane formed by the two positioning steel bars is perpendicular to the connection plane of the curtain wall embedded part, and the plane formed by the two positioning steel bars is perpendicular or parallel to each side of the curtain wall embedded part.

[0018] As a preferred embodiment of the present invention, the steel cage includes a plurality of vertical steel bars and a plurality of structural steel bars for binding the plurality of vertical steel bars. The plurality of vertical steel bars are pre-embedded at the bottom in the building foundation, and the structural steel bars are staggered with the curtain wall pre-embedded parts.

[0019] As a preferred embodiment of the present invention, the steel cage is provided with a template for sealing the vertical components, and the template is provided with tie bolts.

[0020] A construction method for an anti-displacement curtain wall embedded connection structure for installing a building curtain wall, based on the anti-displacement curtain wall embedded connection structure for installing a building curtain wall, includes the following steps:

[0021] Step S1: Structural column processing and pre-embedding. Design and process the corresponding structural columns according to the design requirements, and pre-embed the supporting steel bars of the structural columns and the bottom of the vertical steel bars of the steel cage in the building foundation.

[0022] Step S2: Positioning and fixing of curtain wall embedded parts. Two positioning steel bars are symmetrically welded to both sides of the center point of the curtain wall embedded parts, and the positioning steel bars are welded and fixed to the structural columns through the first fixing steel bar and the second fixing steel bar.

[0023] Step S3: Reinforcing cage binding. The positioning of the curtain wall embedded parts is inspected and accepted. After the inspection is passed, the vertical steel bars are bound together with the structural steel bars to form the reinforcing cage.

[0024] Step S4: Formwork sealing construction;

[0025] Step S5: Concrete pouring to obtain vertical components.

[0026] Compared to existing technologies, the structural columns provide a stable and reliable positioning benchmark. With the dual fixation of positioning and fixing steel bars, the translation and rotation of the curtain wall embedded parts are effectively limited. Under the action of the structural columns that meet the stiffness requirements, the positioning steel bars and the structural columns are welded together with the fixing steel bars to form an integral force system. The welded joints are firm and reliable, which can effectively resist the lateral pressure and impact generated during concrete pouring and vibration. This prevents the curtain wall embedded parts from shifting or tilting during the pouring process, fundamentally avoiding the misalignment of the curtain wall embedded parts and eliminating the need for rework and remediation later.

[0027] By precisely arranging the positioning steel bars (symmetrical about the center point of the embedded plate, forming a plane that is perpendicular to the surface of the embedded plate and perpendicular or parallel to the four sides of the embedded plate), the precise positioning of the curtain wall embedded parts can be achieved, which can meet the millimeter-level precision requirements of high-precision curtain wall projects for the embedded parts of the curtain wall, and completely overcome the technical defects of large positioning error in traditional processes and the inability of existing related patents to restrict the rotation of embedded parts.

[0028] The vertical reinforcement bars of the structural columns and the steel cage are pre-embedded simultaneously and their verticality is strictly controlled to ensure that the structural columns are firmly positioned and can share the load with the building foundation.

[0029] The embedded parts of the curtain wall are fixed by welding positioning steel bars, fixing steel bars and structural columns. There is no need to spot weld the steel cage, which avoids the burning of the main steel bars of the steel cage and the damage to the steel protective layer caused by spot welding. This ensures the load-bearing performance of the main structure, reduces construction safety hazards, and at the same time, all component processing and installation meet the specifications. The construction process is clear and controllable, which further improves the safety and reliability of construction.

[0030] The construction process of this invention is simple, and the processing and installation of structural columns, positioning steel bars, and fixing steel bars are convenient. There is no need for complicated positioning adjustment devices, which can effectively shorten the construction period. At the same time, it eliminates the later rectification work caused by the misalignment of curtain wall embedded parts, and reduces the additional input of labor and materials.

[0031] It is suitable for the pre-embedding construction of various building curtain wall embedded parts, especially for curtain wall projects with high precision requirements such as super high-rise buildings. It can not only meet the positioning requirements of conventional curtain wall embedded parts, but also solve the technical problem of easy displacement of embedded parts under complex working conditions.

[0046] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0047] like Figure 1-13 As shown, a connection structure for an anti-displacement curtain wall embedded component for installing a building curtain wall includes a building foundation 1 and a vertical component 2 connected to the building foundation 1. The bottom of the vertical component 2 is embedded in the building foundation 1. The vertical component 2 is provided with a steel cage 4 and a structural column 3 for supporting the vertical component 2. The structural column 3 is located in the middle of the steel cage 4, and its bottom is embedded in the building foundation 1. The vertical component 2 is provided with a curtain wall embedded component 5 for installing the building curtain wall. The structural column 3 is provided with a connecting component 6 connected to the curtain wall embedded component 5. The connecting component 6 includes a positioning steel bar 61 connected to the anchor rod side of the curtain wall embedded component 5 and a fixing connector for accurately fixing the positioning steel bar 61. The positioning steel bar 61 passes through the structural column 3, and the fixing connector is fixedly connected to the structural column 3.

[0048] The building foundation 1 can be an independent pile cap or a basement roof slab. Before the concrete pouring process of the independent pile cap or basement roof slab, the bottom of the steel cage 4 and the structural column 3 are tied to the steel structure of the independent pile cap or basement roof slab. After the independent pile cap or basement roof slab is poured, the steel cage 4 and the structural column 3 are pre-embedded in the building foundation 1, ensuring that the structural column 3 is firmly positioned and shares the load with the building foundation 1.

[0049] Under the action of the connecting component 6, the curtain wall embedded part 5 is connected to the structural column 3. Under the positioning support of the building foundation 1, the structural column 3 achieves the positioning support of the curtain wall embedded part 5.

[0050] The reinforcing cage 4 is set around the structural column 3, and the reinforcing cage 4 never interferes with the structural column 3 and the curtain wall embedded parts 5. The reinforcing cage 4 is designed according to the required size of the vertical member 2. Under the action of the reinforcing cage 4, the curtain wall embedded parts 5 are embedded in the vertical member 2.

[0051] The structural column 3 includes several vertically arranged supporting steel bars 31 and several annular stirrups 32 connected to the supporting steel bars 31. The fixing connectors are welded and fixed to the supporting steel bars 31.

[0052] The number of supporting steel bars 31 is set according to actual needs. The structural column 3 can be composed of four arrayed supporting steel bars 31. The supporting steel bars 31 are set vertically, and the bottom of the supporting steel bars 31 is embedded in the building foundation 1. The ring stirrups 32 are set horizontally. Under the action of multiple ring stirrups 32 located at different heights of the supporting steel bars 31, the four arrayed supporting steel bars 31 form an integral structural column 3, so that the overall strength of the structural column 3 meets the support requirements of the curtain wall embedded parts 5, ensuring that the structural column 3 can provide stable and reliable support for the positioning of the curtain wall embedded parts 5, and avoiding the positioning deviation of the curtain wall embedded parts 5 due to the deformation of the structural column 3 itself.

[0053] The supporting steel bars 31 of the structural column 3 and the vertical steel bars 41 of the steel cage 4 are simultaneously embedded in the building foundation 1, and the embedding process must strictly meet the verticality requirements. At the same time, the steel cage 4 and the bottom of the structural column 3 are simultaneously anchored in the building foundation 1, avoiding the weak surface caused by later rebar installation and secondary pouring. The vertical component 2 formed by the building foundation 1 and the structural column 3 and the curtain wall embedded parts 5 embedded on the vertical component 2 form a continuous force system with stronger overall rigidity.

[0054] Meanwhile, with the structural column 3 set inside the steel cage 4, the structural column 3 provides the core bearing skeleton for the steel cage 4, and the outer steel cage 4 is equivalent to the additional reinforcing hoops and reinforcing bars for the structural column 3. The structural column 3 and the steel cage 4 jointly bear the axial compression, bending moment and shear force, further ensuring the accurate pre-embedding of the curtain wall embedded parts 5.

[0055] A plurality of supporting steel bars 31 are arranged in an array, and a positioning steel bar 61 passes through the plurality of supporting steel bars 31 arranged in an array. The fixing connector includes a first fixing steel bar 62 and a second fixing steel bar 63 for connecting the positioning steel bar 61 to the supporting steel bars 31.

[0056] The number of supporting steel bars 31 is set according to actual needs. Under the action of the positioning steel bars 61 through the array of several supporting steel bars 31, the same positioning steel bar 61 is welded and fixed on different supporting steel bars 31 by the first fixed steel bar 62 and the second fixed steel bar 63. This ensures that the welding joint of the positioning steel bar 61 is firm and reliable, and ensures that the positioning steel bar 61 and the structural column 3 form an integral force system, thereby achieving the stable fixation of the curtain wall embedded parts 5 and preventing disturbance and displacement during the concrete pouring process.

[0057] The first fixed reinforcing bar 62 and the second fixed reinforcing bar 63 are located on opposite sides of a plurality of supporting reinforcing bars 31 arranged in an array, and the second fixed reinforcing bar 63 is located between the first fixed reinforcing bar 62 and the curtain wall embedded part 5. The first fixed reinforcing bar 62 is welded to the upper and lower sides of the positioning reinforcing bar 61, and the second fixed reinforcing bar 63 is welded to the bottom of the positioning reinforcing bar 61.

[0058] Under the action of the first fixed reinforcing bar 62 and the second fixed reinforcing bar 63, the same positioning reinforcing bar 61 can be welded from different directions to avoid being squeezed or displaced during concrete pouring and vibration. At the same time, the first fixed reinforcing bar 62, the second fixed reinforcing bar 63, the supporting reinforcing bar 31 and the positioning reinforcing bar 61 form a spatial truss connection structure through multi-point welding, thereby sharing the load on the positioning reinforcing bar 61, dispersing stress, making the joint more reliable and durable.

[0059] During construction, the position of the positioning steel bar 61 can be roughly adjusted first, and then multiple first fixed steel bars 62 and second fixed steel bars 63 can be used to gradually correct and spot weld the position. This is easier to level and straighten than single-point welding, reducing installation errors and ensuring the accurate pre-embedding of the curtain wall embedded parts 5.

[0060] The first fixed reinforcing bar 62 and the second fixed reinforcing bar 63 are arranged in parallel, and both the first fixed reinforcing bar 62 and the second fixed reinforcing bar 63 are staggered with the positioning reinforcing bar 61. The first fixed reinforcing bar 62, the second fixed reinforcing bar 63 and the positioning reinforcing bar 61 add multiple transverse restraint bars inside the structural column 3, which not only fixes the positioning reinforcing bar 61, but also indirectly strengthens the rigidity of the cage of the structural column 3.

[0061] The second fixing steel bar 63 is set close to the curtain wall embedded part 5. Under the action of the second fixing steel bar 63, it supports the positioning steel bar 61 and restricts the downward displacement of the curtain wall embedded part 5, without excessively constraining the plane position of the curtain wall embedded part 5. This facilitates fine adjustment of the elevation and center of the curtain wall embedded part 5, ensuring the installation accuracy of the curtain wall embedded part 5.

[0062] The first fixed reinforcing bar 62 is set away from the first fixed reinforcing bar 62. Under the action of the two first fixed reinforcing bars 62 welded to the upper and lower sides of the positioning reinforcing bar 61, a double-sided clamping constraint is formed on the positioning reinforcing bar 61, which can significantly improve the overall rigidity of the positioning reinforcing bar 61. During concrete pouring and vibration, it can effectively resist lateral forces and vibrations and prevent the positioning reinforcing bar 61 from tilting or twisting as a whole.

[0063] Near the curtain wall embedded part 5, only a single second fixing steel bar 63 is used to weld the bottom of the positioning steel bar 61. With fewer welds and less heat concentration, the impact of high welding temperature on the flatness and verticality of the curtain wall embedded part 5 can be greatly reduced, preventing the curtain wall embedded part 5 from warping or deforming due to welding stress, and ensuring the accuracy of the curtain wall embedded part 5 in subsequent use.

[0064] Two positioning steel bars 61 are connected to the curtain wall embedded part 5. The two positioning steel bars 61 are symmetrical about the center of the curtain wall embedded part 5. The positioning steel bars 61 support the position of the curtain wall embedded part 5.

[0065] The plane formed by the two positioning steel bars 61 is perpendicular to the connecting plane of the curtain wall embedded part 5, and the plane formed by the two positioning steel bars 61 is perpendicular or parallel to each side of the curtain wall embedded part 5.

[0066] The steel cage 4 includes several vertical steel bars 41 and several structural steel bars 42 for binding the vertical steel bars 41. The vertical steel bars 41 are pre-embedded at the bottom in the building foundation 1, and the structural steel bars 42 are staggered with the curtain wall embedded parts 5.

[0067] The steel cage 4 is provided with a template 7 for sealing the vertical member 2, and the template 7 is provided with tie bolts 71.

[0068] A construction method for an anti-displacement curtain wall embedded connection structure for installing a building curtain wall, based on the anti-displacement curtain wall embedded connection structure for installing a building curtain wall, includes the following steps:

[0069] Step S1: Fabrication and pre-embedding of structural columns 3. Design and fabricate the corresponding structural columns 3 according to the design requirements, and pre-embed the bottom of the supporting steel bars 31 of the structural columns 3 and the vertical steel bars 41 of the steel cage 4 in the building foundation 1.

[0070] Four supporting steel bars 31 and multiple ring stirrups 32 are welded together to ensure that the structural column 3 meets the preset stiffness requirements. Then, the structural column 3 and the vertical steel bars 41 of the vertical component 2 are simultaneously embedded in the building foundation 1. During the embedding process, a total station is used for monitoring to strictly control the verticality of the structural column 3 to meet the preset verticality requirements. This ensures that the structural column 3 is firmly positioned and can share the load with the building foundation 1, providing a reliable reference support for the subsequent positioning of the curtain wall embedded parts 5.

[0071] Verify the positional relationship between the curtain wall embedded part 5, the structural column 3 and the steel cage 4. Determine that the structural column 3 uses 4 Φ18 threaded steel bars and Φ8 shaped stirrups, the positioning steel bar 61 uses Φ10 threaded steel bars, the first fixing steel bar 62 and the second fixing steel bar 63 use Φ10 threaded steel bars, and the dimensions of the curtain wall embedded part 5 are 300mm×300mm×10mm.

[0072] Using a total station combined with BIM modeling technology, the positioning baseline and elevation control line of the curtain wall embedded parts 5 were accurately marked to ensure positioning accuracy. The structural columns 3 (adapted to the size of the steel cage 4, with 4 supporting steel bars 31 arranged in a rectangle with a spacing of 100mm, and the ring stirrups 32 welded with a spacing of 150mm), positioning steel bars 61, first fixed steel bars 62, second fixed steel bars 63 and curtain wall embedded parts 5 were processed. After the materials passed the inspection upon arrival, they were put into use.

[0073] Step S2: Positioning and fixing of the curtain wall embedded part 5. Two positioning steel bars 61 are symmetrically welded to both sides of the center point of the curtain wall embedded part 5, and the positioning steel bars 61 are welded and fixed to the structural column 3 through the first fixing steel bar 62 and the second fixing steel bar 63.

[0074] On the anchor rod side of the curtain wall embedded part 5, two positioning steel bars 61 are symmetrically welded to both sides of the center point of the curtain wall embedded part 5 along a direction perpendicular to the surface of the curtain wall embedded part 5. This ensures that the plane formed by the two positioning steel bars 61 is perpendicular to the surface of the curtain wall embedded part 5, and that the plane formed by the two positioning steel bars 61 is perpendicular or parallel to the four sides of the curtain wall embedded part 5. The other end of the positioning steel bar 61 is inserted into the pre-embedded structural column 3, and then the positioning steel bar 61 is welded and fixed to the structural column 3 through the first fixing steel bar 62 and the second fixing steel bar 63. This ensures that the welding joint is firm and reliable, so that the positioning steel bar 61 and the structural column 3 form an integral force-bearing system, achieving accurate preliminary positioning and stable fixation of the curtain wall embedded part 5, and effectively limiting the rotation and displacement of the embedded part.

[0075] Step S3: Tie the reinforcing cage 4, inspect the positioning of the curtain wall embedded parts 5, and after the inspection is qualified, tie the vertical reinforcing bars 41 with the structural reinforcing bars 42 to form the reinforcing cage 4.

[0076] After the curtain wall embedded parts 5 have passed the positioning and fixing acceptance, the steel reinforcement cage 4 is tied. During the tying process, avoid collisions and disturbances to the embedded parts, positioning steel reinforcement 61 and structural columns 3, and ensure that the position of the curtain wall embedded parts 5 does not shift. After the structural steel reinforcement 42 is tied, it is accepted according to the specifications.

[0077] Step S4: Formwork sealing construction of template 7. After the steel reinforcement binding is accepted, formwork sealing construction of template 7 is carried out. During the sealing process, the verticality, flatness and firmness of template 7 are strictly controlled to avoid the installation deviation of template 7 affecting the final positioning accuracy of the curtain wall embedded parts 5. After the sealing is completed, template 7 is reinforced to ensure that template 7 does not deform or shift during the pouring process.

[0078] Before sealing the formwork, double-sided tape is applied to the surface of the curtain wall embedded part 5 around the perimeter of the curtain wall embedded part 5. At the same time, during the installation of the formwork 7, the verticality and flatness are strictly controlled to ensure that the curtain wall embedded part 5 and the formwork 7 fit tightly. The reinforcement of the formwork 7 should be firm and reliable to prevent the formwork from deforming during the pouring process and affecting the positioning accuracy of the curtain wall embedded part 5.

[0079] Step S5: Concrete pouring to obtain vertical component 2. The concrete pouring process is monitored in real time. When pouring concrete, the vibration intensity and vibration point arrangement are strictly controlled. It is strictly forbidden for the vibrator to directly hit the curtain wall embedded part 5, positioning steel bar 61, first fixed steel bar 62, second fixed steel bar 63 and structural column 3 to prevent the curtain wall embedded part 5 from being misaligned due to vibration disturbance.

[0080] Concrete is poured in layers. During vibration, over-vibration and under-vibration should be avoided. Vibration points should avoid the curtain wall embedded parts 5, structural columns 3 and positioning steel bars 61. The position of embedded parts 2 should be checked every 30 minutes during the pouring process. The BIM model should be used to compare the measured data and correct minor deviations in a timely manner.

[0081] After the concrete meets the strength requirements, the formwork 7 is removed. During the removal process, avoid collisions with the curtain wall embedded parts 5. After the formwork 7 is removed, all curtain wall embedded parts 5 are comprehensively inspected, including their plane position, elevation, verticality, and flatness with the concrete surface. After the inspection is passed, the curtain wall keel installation process begins.
