Description

Technical Field

[0001] The invention relates to the technical field of structural engineering, in particular to a discontinuous steel plate combined shear wall and a building. Background Art

[0002] At present, in high-rise or super high-rise buildings, shear walls are indispensable load-bearing and lateral-resisting components of the entire structure. The shear walls used more frequently in the prefabricated construction industry are generally steel plate composite shear walls composed of outer steel plates and inner concrete. They are becoming more and more widely used because they can give full play to the characteristics of both steel and concrete and achieve the effect of 1+1>2.

[0003] In actual engineering applications, due to the limitations of steel plate component production length, transportation, and even construction site space, the problem of splicing steel plate walls is inevitable in engineering construction. The current conventional solution to this problem is to weld and splice on the construction site. This solution has the advantages of direct butt joint of steel plates, good continuity of pipe walls, and a simple and smooth appearance at the joints. However, this solution also has its obvious shortcomings, which are mainly manifested in the following aspects: First, the welding process has special technical requirements for construction personnel, who need to master solid welding technology and have considerable experience to ensure the quality of welding. In construction projects, especially high-rise building construction, steel plate walls are usually spliced ​​one on each floor. The joints are usually welded once every two floors or every three floors, so the workload of welds is quite large, and the joint welding of vertical components is usually required to meet the first-level weld standards. How to ensure that there are welding technicians with sufficient qualifications and experience and how to ensure that the quality of each weld is fully up to standard has always been a difficult problem that is not easy to solve, and thus there is a greater quality risk; secondly, welding on the construction site is often open-air welding, which is an operation with electric flames. Not only does it have high requirements on the weather and it is difficult to ensure the welding quality, but it also has high safety risks in construction operations; thirdly, welding assembly usually requires additional welding positioning and fixing steel plates, which need to be cut and leveled after the steel plate wall is spliced, which will further increase the workload of electric welding and steel cutting operations.

[0004] In summary, large-scale on-site welding generally not only has defects such as quality risks, construction difficulty and greater safety risks, but is also labor-intensive and time-consuming. Summary of the invention

[0005] Based on this, it is necessary to provide a discontinuous steel plate combined shear wall and building, aiming to solve the problems of large welding workload, high construction difficulty and safety risks in the existing technology.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] like Figure 1 As shown, a discontinuous steel plate composite shear wall of a wall body steel plate 52 is shown in an embodiment of the present application, which includes: a first hidden column 10, a second hidden column 20 and a wall body 50. The steel plate composite shear wall (abbreviated as the discontinuous steel plate composite shear wall of the wall body steel plate 52, the same below) plays a vital role as an indispensable load-bearing component and lateral resistance component in the entire structure.

[0028] In this embodiment, the first hidden column 10 and the second hidden column 20 are arranged side by side with an interval, and are both installed in a vertical plane perpendicular to the ground. The first hidden column 10 and the second hidden column 20 both include hidden column inner concrete 30, and hidden column outer steel plate 40 wrapped outside the hidden column inner concrete 30; the wall body 50 includes wall body inner concrete 51, and wall body steel plate 52 wrapped outside the wall body 50 inner concrete, the wall body steel plate 52 includes at least two steel plate units 521, at least two ends of the steel plate units 521 are respectively connected to the hidden column outer steel plate 40 on both sides as a whole, and at least two steel plate units 521 are arranged side by side along the height direction of the wall body 50, and any two adjacent steel plate units 521 are intermittently arranged to form a horizontal seam 60, and the horizontal seam 60 is disconnected at each floor or after a certain number of floors.

[0029] It can be understood that the concealed column outer steel plate 40 and the wall steel plate 52 are connected as a whole by welding, with high connection reliability, high overall structural strength, and excellent load-bearing and lateral resistance capabilities.

[0030] The beneficial effect of implementing the technical solution of the above embodiment is that the above-mentioned wall steel plate 52 discontinuous steel plate combined shear wall is composed of the first hidden column 10, the wall 50 and the second hidden column 20, wherein the wall 50 is connected between the first hidden column 10 and the second hidden column 20, the concrete 30 in the hidden column is connected to the concrete 51 in the wall body, and can be cast and formed in one piece at a time, with low construction difficulty and good molding quality. In addition, the hidden column outer steel plate 40 is also connected to the steel plate unit 521, with high connection strength and good integrity of the shear wall. And because a horizontal seam 60 is formed between any two adjacent steel plate units 521 due to the intermittent setting, and the horizontal seam 60 can correspond to each floor, or be set after a certain number of floors, the welding construction amount during the installation of the wall steel plate 52 can be greatly reduced, that is, due to the existence of the horizontal seam 60, the welding operation can be avoided. In addition, the skill level requirements for construction personnel are reduced, the construction difficulty is reduced, and at the same time, there is no need for construction personnel to weld for a long time at high altitude, and the potential safety risk of falling from a height is effectively eliminated.

[0031] In some embodiments, the horizontal seam 60 is configured as a continuous through-slot structure, and the two ends of the horizontal seam 60 are respectively connected to the left and right sides of the concealed column outer steel plates 40. The horizontal seam 60 is designed and manufactured as a continuous through-slot structure, and the molding structure of the horizontal seam 60 is simpler. Since the two ends of the horizontal seam 60 are directly connected to the left and right sides of the concealed column outer steel plates 40, that is, there is no connection part, it is conducive to further reducing the welding construction amount of the steel plate unit 521 and the concealed column outer steel plates 40.

[0032] Of course, as an alternative to the above embodiment, the horizontal seam 60 may also be provided as a discontinuous multi-segment groove structure, that is, the horizontal seam 60 includes at least two sections of connecting seams 61 that are discontinuously connected, and at least two sections of the connecting seams 61 are arranged side by side at intervals.

[0033] The horizontal seam 60 is designed to be composed of at least two sections of connecting seams 61 connected discontinuously. On the basis of reducing the amount of welding construction, improving quality and efficiency and eliminating hidden dangers, the two adjacent steel plate unit elements 521 can be connected as one, which helps to ensure the overall structural performance of the wall steel plate 52, so that the steel plate composite shear wall has reliable load-bearing and lateral resistance capabilities.

[0034] For example, this application Figure 2 FIG. 5 shows an arrangement scheme in which five sections of connecting seams 61 are connected intermittently. And the five sections of connecting seams 61 are arranged on the same straight line.

[0035] In other embodiments, the horizontal seam 60 is configured as a discontinuous multi-section groove structure, that is, the horizontal seam 60 includes at least two discontinuously connected connecting seams 61, at least two connecting seams 61 are arranged at intervals along the width direction of the wall body 50, and at least two connecting seams 61 are staggered in the height direction of the wall body 50.

[0036] The difference from the above embodiment is that the connecting seams 61 are not arranged on the same straight line, but are staggered in a straight line direction along the height direction of the wall body 50, that is, a corrugated structure similar to wave crests and troughs is formed. This allows a certain size error when the horizontal seam 60 is made, and can also meet the purpose of reducing the welding workload. At the same time, the staggered connecting seams 61 can form a specific pattern arrangement, which can increase the appearance of the steel plate composite shear wall to a certain extent.

[0037] According to actual needs, and on the basis of allowing a certain range of assembly errors of the steel plate unit 521 and positioning processing errors of the horizontal seam 60, the horizontal seam 60 is arranged directly opposite the corresponding floor, or arranged above the corresponding floor, or arranged below the corresponding floor.

[0038] Preferably, the horizontal seams 60 are horizontally aligned with the corresponding floors.

[0039] Furthermore, according to actual needs, the horizontal seam 60 is set to a straight, curved or corrugated structure. Therefore, the molding structure of the horizontal seam 60 is diverse, meeting different construction needs, and helping to enhance the manufacturability of the steel plate composite shear wall.

[0040] In addition, according to conventional construction techniques, when the steel plate composite shear wall is manufactured on site, the outer steel plate 40 of the hidden column and the wall steel plate 52 are generally spliced ​​to form the necessary wall shell, and then concrete is poured into the cavity formed inside the wall shell to form the hidden column concrete 30 and the wall concrete 51. When facing some concrete materials with general fluidity and large medium particles of concrete, the concrete slurry usually does not leak out from the horizontal seam 60 during pouring; while for concrete materials with strong fluidity and small medium particles, there will be a problem of concrete leaking from the horizontal seam 60. Based on this, on the basis of any of the above embodiments, the wall steel plate 52 discontinuous steel plate composite shear wall also includes a spare plugging mechanism, which is arranged on the steel plate unit 521 and is used to plug the horizontal seam 60 when needed. Therefore, when it is necessary to plug the horizontal seam 60 to prevent the leakage of concrete slurry during pouring, the spare plugging mechanism can quickly and reliably plug the horizontal seam 60.

[0041] Specifically, in some embodiments, the backup sealing mechanism includes a guide rail, a sliding assembly, a sealing shell, a sealing actuator, a first hook and a second hook, the guide rail is arranged on one side of the horizontal seam 60, the sliding assembly is movably arranged on the guide rail and connected to the sealing shell; the sealing shell includes a plurality of retractable and nested unit shell plates, the first hook is arranged on the unit shell plate at the starting point and is hooked and fixed with one end of the horizontal seam 60, the second hook is arranged on the unit shell plate at the end and can be hooked and fixed with the other end of the horizontal seam 60, the sealing actuator is arranged on the sealing shell, and can cover the horizontal seam 60 when each unit shell plate is stretched and unfolded, and the sealing actuator can seal and seal the horizontal seam 60.

[0042] The guide rail guides and supports the reciprocating sliding of the plugging shell, so that the plugging shell can be pre-installed and fixed on the steel plate unit 521. Specifically, the plugging shell is fixed to the inner wall of the steel plate unit 521 by the first hook body and the second hook body, and the installation method is simple, and the connection is reliable and stable. When the spare plugging mechanism is not needed, the multi-section unit shell plates are mutually contracted and nested and overlapped, which takes up little space and is beautiful. When the horizontal seam 60 needs to be plugged, it is only necessary to pull the end (that is, the outermost) unit shell plate to slide toward one end of the horizontal seam 60, and each section of the unit shell plate slides and stretches and unfolds successively. It can be understood that the overlapping area of ​​each unit shell plate gradually decreases at this time. Until each unit shell plate is fully stretched and opened to cover the horizontal seam 60, in this process, the plugging actuator is stretched and lengthened and the horizontal seam 60 is completely filled, so that the horizontal seam 60 is plugged, ensuring that the internal concrete slurry cannot leak out from the horizontal seam 60.

[0043] It can be understood that the above-mentioned blocking actuator can be but is not limited to rubber, silicone, etc. with excellent expansion and contraction deformation capabilities.

[0044] Furthermore, in some other embodiments, the wall body steel plate 52 discontinuous steel plate combined shear wall also includes a driver and a controller, the controller is electrically connected to the driver, and the driver is drivingly connected to the unit shell plate. The construction personnel remotely operate the controller, and the controller can automatically control the driver to start, and the driver automatically completes the pulling and moving of the unit shell plate to achieve the purpose of the plugging actuator to plug the horizontal seam 60. The automation is high, and no human climbing operation is required, which can reduce labor costs and eliminate the hidden dangers of falling safety.

[0045] In addition to the above, the present application also provides a building, which includes a discontinuous steel plate combined shear wall of the wall steel plate 52 as described in any of the above embodiments.
