Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a positioning device for connecting a core tube shear wall with an outer frame and stubble steel bars. Background Art

[0002] The core tube shear wall and outer frame in building construction are important components of the building structure. They each assume different functions and are connected to ensure the overall stability and safety of the building. Among them, the core tube shear wall is an important component in the building structure for resisting horizontal loads (such as wind loads and seismic loads). It is usually made of reinforced concrete to form a core tube with large lateral stiffness. The outer frame refers to the external frame structure surrounding the core tube. It is usually composed of steel beams, steel tube concrete columns, etc., and together with the core tube, it constitutes a dual lateral force resistance system of the building structure. Specifically in the building structure, the core tube shear wall is used to set up stairs, elevators and other building structures in the middle; while the outer frame is used to set up housing space and other functions outside the core tube shear wall. A flat corridor can be set between the core tube shear wall and the outer frame.

[0003] In super high-rise buildings, the core tube shear wall bears the main role in resisting lateral forces, while the outer frame provides external support. In order to enhance the collaborative work between the two, stub steel bars are usually embedded in the core tube shear wall to serve as a connecting medium between the outer frame and the core tube shear wall. At present, in high-altitude and narrow construction environments, the process of embedding stub steel bars often has problems such as inaccurate positioning, insufficient anchoring of steel bars, and weak bonding with concrete, all of which will affect the overall stress performance and safety of the building structure. At the same time, the embedded stub steel bars are usually located at the K-plate aluminum formwork, so the stub steel bars need to pass through the K-plate aluminum formwork and extend outward. After the pouring is completed, due to the solidification of the concrete, it is difficult to smoothly disassemble and separate the K-plate aluminum formwork from the stub steel bars, which will lead to external force damage to the K-plate aluminum formwork and increase operating costs.

[0004] At present, in order to reduce the damage to the K-plate aluminum formwork, a wooden formwork is used instead of the K-plate aluminum formwork. After the pouring and solidification, the damaged wooden formwork is directly separated from the stubble steel bars. Although this method has a lower cost than the K-plate aluminum formwork, it still causes a great waste of the wooden formwork. At the same time, the strength of the wooden formwork and other aspects cannot have the same effect as the K-plate aluminum formwork, which will affect the pouring quality of the concrete and the anchoring tightness of the stubble steel bars. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a positioning device for the steel bars connecting the core tube shear wall and the outer frame, which can effectively overcome the adhesion between the concrete and the K-plate aluminum formwork, so that the K-plate aluminum formwork can be smoothly disassembled, while ensuring that the K-plate aluminum formwork is not damaged by disassembly, solving the current problems of the K-plate aluminum formwork being difficult to disassemble, and the problem of external force damage during disassembly using wooden formwork and the inability to effectively replace the function of the K-plate aluminum formwork.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a positioning device for connecting the core tube shear wall and the outer frame with the stubble steel bars, the stubble steel bars are located at the K-plate aluminum formwork of the core tube shear wall, and are characterized in that: the stubble steel bars pass through the K-plate aluminum formwork and the K-plate aluminum formwork can be offset compared to the stubble steel bars, and a positioning component for positioning the stubble steel bars is also provided on the K-plate aluminum formwork, and the positioning component can seal the stubble steel bars passing through the K-plate aluminum formwork.

[0007] Preferably, a long hole corresponding to each of the discarded steel bars is opened on the K-plate aluminum mold.

[0008] Preferably, the positioning member is an adjustably mounted slide plate mounted on the K-plate aluminum mold, and a positioning sealing hole having the same structure as the long strip hole is provided on the slide plate.

[0009] Preferably, a locking screw is symmetrically provided on the K-plate aluminum mold at a horizontal position corresponding to the stubble steel bar, an L-shaped plate is sleeved on the locking screw to abut against the side of the stubble steel bar, and the slide plate slides between the L-shaped plate and the locking screw through its positioning sealing hole.

[0010] The beneficial effects of the present application are: the positioning device passes the stubble steel bars through the K-plate aluminum formwork and the K-plate aluminum formwork can be offset compared to the stubble steel bars. Its structure increases the relative range of movement of the K-plate aluminum formwork and the stubble steel bars. After the concrete pouring is completed, by driving the K-plate aluminum formwork to offset compared to the stubble steel bars, the adhesion force between the concrete and the K-plate aluminum formwork can be effectively overcome. At the same time, the connection between the K-plate aluminum formwork and the stubble steel bars is separated under the offset operation, so that the K-plate aluminum formwork can be smoothly disassembled, and at the same time, the K-plate aluminum formwork is ensured not to be damaged by disassembly, solving the current problems of the K-plate aluminum formwork being difficult to disassemble, and the problem of external force damage and inability to effectively replace the function of the K-plate aluminum formwork when using wooden formwork for disassembly.

[0011] This positioning member can be used to position the stubble rebar, preventing the K-plate aluminum formwork from offsetting the stubble rebar and causing inaccurate positioning of the stubble rebar. Furthermore, the positioning member can block the stubble rebar's penetration into the K-plate aluminum formwork, effectively preventing grout leakage during the pouring process.

[0021] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Refer to the attached Figures 1 to 8 The present invention relates to a positioning device for connecting the core tube shear wall and the outer frame with the stubble steel bar. The stubble steel bar 1 is located at the K-plate aluminum form 2 of the core tube shear wall. When the concrete pouring is completed and the K-plate aluminum form 2 is dismantled, the penetration and solidification of the concrete will cause the stubble steel bar 1 and the K-plate aluminum form 2 to be blocked and solidified at the position where the stubble steel bar 1 and the K-plate aluminum form 2 are inserted, making it difficult to dismantle the K-plate aluminum form 2. Therefore, in order to solve this problem, Figure 4As shown, the stubble steel bar 1 passes through the K-plate aluminum formwork 2 and the K-plate aluminum formwork 2 can be offset compared to the stubble steel bar 1. This structure increases the relative range of movement of the K-plate aluminum formwork 2 and the stubble steel bar 1. After the concrete pouring is completed, the adhesion force between the concrete and the K-plate aluminum formwork is effectively overcome by driving the K-plate aluminum formwork 2 to offset compared to the stubble steel bar 1. At the same time, the offset operation causes the connection between the K-plate aluminum formwork 2 and the stubble steel bar 1 to be separated, so that the K-plate aluminum formwork 2 can be smoothly disassembled while ensuring that the K-plate aluminum formwork 2 is not damaged by disassembly.

[0023] The K-plate aluminum mold 2 is in an offset state compared to the stubble steel bar 1, which affects the positioning accuracy of the stubble steel bar 1. Therefore, in order to solve this problem, Figure 6 As shown, a positioning component for positioning the stubble steel bars 1 is also provided on the K-plate aluminum mold 2. The positioning component can be used to position the stubble steel bars 1, thereby avoiding the problem of inaccurate positioning of the stubble steel bars 1 caused by the offset of the K-plate aluminum mold 2 compared to the stubble steel bars 1.

[0024] At the same time, the positioning component can block the penetration of the stubble steel bars 1 on the K-plate aluminum mold 2, that is, it can effectively solve the problem of leakage at the penetration of the stubble steel bars 1 on the K-plate aluminum mold 2 during the pouring process.

[0025] Specifically, such as Figure 3 As shown, a long hole 2a corresponding to each of the stubble steel bars 1 is opened on the K-plate aluminum mold 2. When the K-plate aluminum mold 2 is disassembled after the concrete pouring is completed and solidified, as shown in FIG. Figure 4 As indicated by the middle arrow, the K-plate aluminum formwork 2 is driven up and down to offset the stubble rebar 1, thereby overcoming the concrete's adhesion to the K-plate aluminum formwork 2 and the difficulty in removing the K-plate aluminum formwork 2 due to the small size of the perforations in the K-plate aluminum formwork 2 adapted for the stubble rebar 1. This structure not only solves the problem of damage and waste caused by the current use of wooden formwork during removal, but also preserves the original function of the K-plate aluminum formwork 2.

[0026] Specifically, such as Figure 5-7 As shown, the positioning member is an adjustable slide 3 mounted on the K-plate aluminum mold 2, and a positioning blocking hole 3a having the same structure as the long hole 2a is opened on the slide 3. Since the K-plate aluminum mold 2 usually has a flange 21 on the side, the slide 3 can be mounted on the flange, such as Figure 6The structure shown. When the slide plate is in use, it is first aligned with the long hole 2a through its positioning and blocking hole 3a, and then the stubble steel bar is passed through the overlapping hole position, and the slide plate 3 is lifted up and the K-plate aluminum mold 2 is moved down. The upper and lower misalignment of the long hole 2a and the positioning and blocking hole 3a is used to achieve the positioning against the upper and lower sides of the stubble steel bar 2. At the same time, in this state, the slide plate 3 and the K-plate aluminum mold 2 block the leaking part of the long hole 2a and the positioning and blocking hole 3a except for the stubble steel bar 1, and the upper end of the slide plate 3 is inserted into the perforation of the flange, and the slide plate 2 is fastened to the flange by double nuts (nuts are sleeved on the slide plate 3 on the upper and lower sides of the flange), so that on the basis of positioning the stubble steel bar 1, its penetration position is blocked, thereby avoiding the problem of leakage.

[0027] After the concrete pouring is completed, the slide plate 3 is first removed from the flange of the K-plate aluminum formwork 2, and then the K-plate aluminum formwork 2 is driven up and down to separate and remove it from the concrete and the stubble steel bars 1. On the basis of positioning the stubble steel bars 1, the K-plate aluminum formwork 2 is conveniently disassembled, and the position where the stubble steel bars 1 are passed through is sealed to avoid leakage.

[0028] There is still a gap in the horizontal direction when the stubble steel bar 1 is passed through the long hole 2a, which affects the horizontal positioning accuracy of the stubble steel bar 1. Therefore, in order to further improve the positioning accuracy of the stubble steel bar 1, Figure 7-8 As shown, a locking screw 4 is symmetrically provided on the K-plate aluminum mold 2 at a horizontal position corresponding to the stubble steel bar 1. An L-shaped plate 5 is sleeved on the locking screw 4 to abut against the side of the stubble steel bar 1, and the slide plate 3 is slidably sleeved between the L-shaped plate 5 and the locking screw 4 through its positioning and blocking hole 3a. After the stubble steel bar 1 is positioned by the upper and lower misalignment of the slide plate 3 and the K-plate aluminum mold 2, the L-shaped plate 5 is then sleeved on the locking screw 4. When the locking screw 4 is connected to the K-plate aluminum mold 2, the side of the positioning and blocking hole 3a of the slide plate 3 is simultaneously clamped between the locking screw 4 and the L-shaped plate 5, so that the slide plate 3 and the K-plate aluminum mold 2 are flat against each other, so as to achieve the blocking of the leaking parts of their respective holes after the two are misaligned. And by the side wall of the L-shaped plate 5 abutting against the stubble steel bar 1, the relative positioning of the stubble steel bar 1 in the horizontal direction is achieved. Further preferably, an arcuate groove 5a is provided on the side wall of the L-shaped plate 5, and the arcuate groove is embedded in the side wall of the stubble steel bar 1 to further improve the positioning effect of the stubble steel bar 1.

[0029] The principle of this application is: when positioning the stubble steel bar 1, first, the slide plate 3 is flatly attached to the surface of the K-plate aluminum mold 2, and the positioning sealing hole 3a is made to coincide with the long hole 2a, and then the stubble steel bar 1 is inserted into the corresponding hole, and then the slide plate 3 and the K-plate aluminum mold 2 are moved up and down, and the vertical positioning of the stubble steel bar 1 is achieved by utilizing the upper and lower misalignment of the positioning sealing hole 3a and the long hole 2a, and at the same time, the leaking parts of the positioning sealing hole 3a and the long hole 2a are blocked with each other, and then the slide plate 3 is fixed to the flange on the upper side of the K-plate aluminum mold 2 by a double nut.

[0030] Then the L-shaped plate 5 is put on the locking screw 4. When the locking screw 4 is connected to the K-plate aluminum mold 2, the side of the positioning sealing hole 3a of the slide plate 3 is clamped between the locking screw 4 and the L-shaped plate 5. The locking screw 4 is connected to the K-plate aluminum mold 2 and tightened. The side wall of the stubble steel bar 1 is abutted by the L-shaped plate 5 to achieve horizontal lateral positioning of the stubble steel bar 1.

[0031] After the concrete is poured and solidified, the slide plate 3 is first removed from the flange, and then the K-plate aluminum formwork 2 is driven up and down to separate and disassemble it from the concrete and the stubble steel bars 1.

[0032] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
