Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering, concretely relates to a kind of adjustable connecting component for basement shear wall gap construction.The component is used in shear wall structure in underground building, can effectively adjust gap width when carrying out wall construction, to improve construction accuracy and construction efficiency.Specifically, the connecting component of the application is mainly applied in the construction process of basement wall and its joint, solves the problems of gap adjustment difficulty and unstable structure in the prior art, and has good adaptability and adjustment function. BACKGROUND

[0002] In urban construction, more and more large buildings, high-rise and super high-rise building structures, in order to solve the problem of settlement deformation of such structures, it is usually necessary to set a deformation joint at the shear wall of the structure, and the shear wall on both sides is usually difficult to control due to the short distance between them: the gap between the shear walls is usually difficult to ensure uniformity, especially when constructing in a small space, there are many problems such as difficulty in template installation and removal, difficulty in fixing, inconvenience in reinforcing, and difficulty in controlling the precision of concrete pouring. The traditional construction method is to first bind the reinforcement of one side of the concrete wall, set up the formwork, pour the concrete, and at the same time, add extractable tension bolts. After the formwork is removed, a polyphenyl foam board with the same thickness as the deformation joint is attached to the poured concrete wall. Then, the reinforcement on the other side is bound, the single formwork on the other side is set up, and the formwork is reinforced using the existing tension bolt holes and specially designed extended tension bolts on the poured concrete wall. Then, the concrete is poured, and the polyphenyl board is squeezed in the middle of the deformation joint. This method can fully ensure the quality of the main structure. The traditional method often relies on manual adjustment and traditional formwork, resulting in low construction efficiency and poor precision, and the polyphenyl board is not removed cleanly, which can cause white pollution and structural quality problems such as serious misalignment of the shear walls at the joint of each floor, uneven deformation joint, and the like. SUMMARY

[0003] The utility model aims at providing a kind of adjustable connecting component for basement shear wall gap construction, the connecting component includes main connecting body and adjusting device common composition, main connecting body and shear wall are adjusted gap width between shear wall by the transverse horizontal force generated by adjusting device, while the position of adjusting device can be adjusted along the longitudinal direction through the channel, which ensures the consistency of each deformation joint width and simplifies the construction precision control.

[0004] The utility model realizes the following technical scheme:

[0005] An adjustable connecting component for basement shear wall gap construction, comprising:

[0006] A main connector is supported between the shear walls;

[0007] An adjusting device is arranged in multiple groups and connected between the main connectors to adjust the gap between the main connectors.

[0008] The main connector includes a pair of connecting plates arranged oppositely, and the opposite walls of the connecting plates are spaced from top to bottom and arranged with multiple grooves matching the ends of the adjusting device.

[0009] In this scheme, the main connector is an important component directly supported between the shear walls, and the oppositely arranged connecting plates and the multiple grooves matching the ends of the adjusting device arranged from top to bottom on the opposite walls of the connecting plates jointly build the basic framework of the entire adjusting system. These grooves serve as guide rails to provide accurate positioning and guiding paths for the installation and position adjustment of the adjusting device, ensuring that the adjusting device can stably and accurately function; meanwhile, the adjusting device is arranged in multiple groups and closely connected between the main connectors, becoming the core power unit for realizing the flexible adjustment of the gap between the main connectors. In the actual construction process, the construction personnel can fine-tune the gap in each direction between the main connectors according to the specific design requirements and construction conditions, using the movement and adjustment of the adjusting device in the grooves to ensure the consistency of the width of each deformation joint, greatly simplifying the construction precision control difficulty compared with the prior art.

[0010] As a further technical scheme of the adjustable connecting member, the adjusting device includes a bolt support and a screw rod.

[0011] The bolt supports are arranged in pairs, one end of each pair of bolt supports is inserted into the groove of the main connector, and the other end of each pair of bolt supports is arranged oppositely and connected with the screw rod through the adjusting part.

[0012] In this scheme, the bolt supports are arranged in pairs and one end is inserted into the groove of the main connector, providing a stable support point and positioning foundation for the adjusting device, ensuring the reliability of its installation on the main connector; the other end is connected with the screw rod through the adjusting part, so that the construction personnel can efficiently change the relative position of the bolt support by rotating the screw rod, and then accurately adjust the gap between the main connectors, realizing the precise control of the gap width of the shear wall, effectively solving the problem of gap adjustment in the traditional construction method.

[0013] As a further technical scheme of the adjustable connecting member, the adjusting part includes adjusting nuts located at both ends of the screw rod, which are threadedly connected with the screw rod and tightly pressed against the ends of the bolt support.

[0014] In the present scheme, the adjusting nuts at both ends of the screw are threadedly connected with the screw, and the position of the adjusting nuts on the screw can be accurately changed by rotating, so as to exert different degrees of jacking force on the end of the bolt support. In actual construction, the design can finely adjust the gap between the main connecting bodies, and ensure that the gap width meets the high-precision standard of the design requirement.

[0015] As a further technical scheme of the adjustable connecting member, the adjusting part further comprises a locking nut located outside the adjusting nut and threadedly connected with the screw.

[0016] In the present scheme, when the construction personnel accurately adjust the position of the bolt support and the gap between the main connecting bodies by using the adjusting nut, the locking nut located outside the adjusting nut is threadedly connected with the screw, which can further tighten the entire adjusting device. In the subsequent construction process, especially during concrete pouring, it can effectively resist various external force impacts and vibration disturbances, and prevent the adjusting nut from loosening due to external factors, so as to ensure that the gap width of the shear wall set in advance remains stable.

[0017] As a further technical scheme of the adjustable connecting member, the bolt support comprises a pair of legs, and the pair of legs are respectively inserted into the adjacent grooves on the same side.

[0018] In the present scheme, the way of inserting the legs into the adjacent grooves on the same side significantly enhances the connection stability of the bolt support and the main connecting body. Compared with the design of a single connection point, it can more evenly disperse the force generated during the adjustment process, and avoid excessive local stress on the main connecting body.

[0019] As a further technical scheme of the adjustable connecting member, a plastic pad is arranged between the main connecting body and the shear wall, and the plastic pad is tightly attached to the connecting plate.

[0020] In the present scheme, the plastic pad can effectively fill the small gap between the main connecting body and the shear wall, play a buffering role, and prevent damage to the shear wall caused by wear or collision during the construction process due to direct contact between the two. The close-fitting characteristic can also enhance the friction between the main connecting body and the shear wall, making the main connecting body more stable during adjustment and fixation, and helping to maintain the gap width after adjustment. At the same time, the plastic pad can block the invasion of external moisture, dust and other impurities to a certain extent, and protect the surface of the shear wall.

[0021] As a further technical scheme of the adjustable connecting member, the plastic pad is made of an elastic composite material.

[0022] As a further technical solution of the adjustable connecting member, the adjustable connecting member further comprises a limiting device connected to the bottom of the connecting plate, so that the connecting plate moves in the opposite direction during adjustment.

[0023] In this scheme, when it is necessary to adjust the gap between the main connecting bodies to control the width of the shear wall gap, the limiting device ensures that the connecting plate can only move stably in the opposite direction, avoiding unstable conditions such as deviation and shaking of the connecting plate, thereby ensuring the accuracy and standardization of the adjustment process.

[0024] As a further technical solution of the adjustable connecting member, the limiting device comprises a first limiting member and a second limiting member, the first limiting member and the second limiting member are respectively connected between the oppositely arranged connecting plates, and a limiting groove matching the second limiting member is formed in the middle of the first limiting member.

[0025] In this scheme, the first limiting member and the second limiting member are respectively connected to the opposite connecting plates to form a stable structural association. The limiting groove in the middle of the first limiting member matches the second limiting member, which effectively restricts the movement path of the connecting plate during adjustment, so that it moves strictly according to the predetermined direction and range, avoiding deviation or excessive displacement. It provides accurate spatial guidance for adjustment operations, ensuring that each adjustment can accurately control the gap between the main connecting bodies, thereby stabilizing the width of the shear wall gap, greatly improving the construction precision and ensuring the stability and construction quality of the basement shear wall structure.

[0026] As a further technical solution of the adjustable connecting member, the inner wall surface of the limiting groove is provided with a plurality of regularly arranged concave-convex limiting grids.

[0027] In this scheme, when the first limiting member and the second limiting member interact during adjustment, these concave-convex limiting grids can provide additional positioning and limiting functions. They can accurately hold the second limiting member to prevent unnecessary sliding or deviation of the second limiting member in the limiting groove, further ensuring the movement accuracy and stability of the connecting plate during adjustment.

[0028] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0036] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the utility model is further explained in detail below with examples and drawings, and the illustrative embodiment and its explanation of the utility model are only used to explain the utility model, and not as the limitation to the utility model.

[0037] Example 1

[0038] This embodiment 1 provides a kind of adjustable connecting component for basement shear wall gap construction, as shown in Figure 1 It includes main connecting body and adjusting device, and main connecting body is supported between shear wall 1, adjusting device is set multiple groups and is connected between main connecting body, so that the gap between main connecting body is adjustable.

[0039] As shown in Figure 1 Main connecting body includes a pair of connecting plate 8, and connecting plate 8 is rectangular in shape, and is made of steel plate or steel material with appropriate thickness, is designed according to the width of actual demand and wall thickness, and the size is usually between 50cm to 200cm, and the thickness is generally between 4mm to 10mm, to ensure that there is enough strength to withstand the pressure of shear wall 1, while connecting plate 8 is oppositely arranged, and plastic pad 3 is attached to the outer side wall of connecting plate 8, and plastic pad 3 is tightly attached to shear wall 1 by formwork 2, and in this embodiment, the plastic pad 3 is made of elastic composite material, and the elastic composite material can be CFRP or GFRP.

[0040] Meanwhile, the opposite wall surface of the connecting plate 8 is provided with a plurality of grooves 9 matched with the end of the adjusting device from top to bottom at intervals, which provides precise positioning and guiding path for the installation and position adjustment of the adjusting device. In the actual construction process, the construction personnel can fine-tune the gap between the main connecting bodies according to the specific design requirements and construction conditions, and the movement and adjustment of the adjusting device in the groove 9 can ensure the consistency of the width of each deformation joint.

[0041] Among them, please refer to Figure 1 As shown in the figure, the adjusting device includes a bolt support 7 and a screw rod 4. The bolt support 7 is provided in pairs. One end of the bolt support 7 provided in pairs is arranged in the groove 9, and the other end is arranged opposite to each other and is connected with the screw rod 4 through the adjusting part, so that the construction personnel can efficiently change the relative position of the bolt support 7 by rotating the screw rod 4, and then accurately adjust the gap between the main connecting bodies by means of the screw thread transmission principle. Specifically, the adjusting part includes adjusting nuts 6 at both ends of the screw rod 4. The adjusting nuts 6 are threadedly connected with the screw rod 4 and are respectively tightly arranged at the end of the bolt support 7. At the same time, the locking nuts 5 are connected outside the adjusting nuts 6. The locking nuts 5 are also threadedly connected with the screw rod 4. By rotating the adjusting nuts 6, the position of the adjusting nuts 6 on the screw rod 4 can be accurately changed, and then the end of the bolt support 7 is applied with different degrees of tightening force. When the gap adjustment is completed, the locking nuts 5 outside the adjusting nuts 6 are threadedly connected with the screw rod 4, which can further tighten the entire adjusting device. The advantage of this setting is that the gap of a certain side main connecting body can be fine-tuned independently. In some embodiments, the screw rod 4 and the bolt support 7 can be threadedly connected, and an outer flange can be arranged in the middle of the screw rod 4. By rotating the outer flange, the gap of the two end main connecting bodies can be adjusted synchronously. However, this method cannot fine-tune the gap of a certain side main connecting body independently.

[0042] At the same time, in some embodiments, in order to avoid excessive force on the main connecting body, the above-mentioned bolt support 7 includes a pair of legs, which are respectively inserted into the adjacent grooves 9 on the same side. In this way, the force generated during the adjustment process can be more evenly distributed.

[0043] Embodiment 2

[0044] This embodiment 2 provides an adjustable connecting component for basement shear wall gap construction based on the technical solution of embodiment 1, like Figure 1As shown, the adjustable connecting member further comprises a limiting device connected to the bottom of the connecting plate 8 to move the connecting plate in the opposite direction during adjustment. Specifically, the limiting device comprises a first limiting piece 10 and a second limiting piece 12 connected between the oppositely arranged connecting plates 8, respectively. The middle part of the first limiting piece 10 is provided with a limiting groove matching the second limiting piece 12. The inner wall surface of the limiting groove is provided with a plurality of regularly arranged concave-convex limiting grids 11. During adjustment, the limiting device guides the connecting plate 8 to move in the opposite direction to prevent deviation. The concave-convex limiting grids further ensure the accuracy and stability of movement, guarantee the consistency of the width of each deformation joint, and effectively improve the construction accuracy.

[0045] The working process of the adjustable connecting member is as follows:

[0046] Firstly, during the early construction preparation stage, the specifications and models of the adjustable connecting member are determined according to the design requirements of the shear wall, and are transported to the construction site. The size and material of the main connecting body should be adapted to the wall thickness and construction environment. The accuracy and strength of the screw rod 4, bolt support 7, nut and other components of the adjusting device should be ensured.

[0047] When the construction starts, the carpentry team builds the side retaining wall formwork, places the main connecting body between the shear walls 1, makes the plastic pads 3 on the outer side of the connecting plate 8 tightly fit the formwork 2, and uses the preliminary fixing measures (such as temporary bolts) to ensure the stable position of the main connecting body. At this time, the bolt supports 7 of the adjusting device are inserted into the channel 9 of the connecting plate 8 of the main connecting body in pairs, the screw rod 4 passes through the bolt support 7 and is screwed with the adjusting nut 6 and the locking nut 5, but is not tightened temporarily.

[0048] Then, the gap width adjustment link is entered. The construction personnel rotate the screw rod 4 according to the designed deformation joint width using tools. The rotation of the screw rod 4 drives the bolt support 7 to slide in the channel 9. Since the main connecting body is connected with the shear wall 1 through the horizontal force generated by the adjusting screw rod 4, the main connecting body will move relatively to change the gap width between the walls. During the adjustment process, the gap size can be monitored in real time by using measuring tools. When the predetermined width is reached, the adjusting nut 6 is tightened to tightly press the end of the bolt support 7, further fixing the position of the adjusting device. Then, the locking nut 5 is tightened to prevent the screw rod 4 from loosening, ensuring that the gap width remains stable in subsequent construction.

[0049] During the concrete pouring stage, the stable adjustable connecting member maintains the accurate width of the wall gap, resists the impact force and vibration force during concrete pouring, ensures the stability of the formwork system, and prevents problems such as formwork expansion and grouting leakage. At the same time, the plastic pads 3 between the main connecting body and the shear wall tightly fit the formwork, effectively preventing water from seeping from the gap, and improving the waterproof effect of the basement.

[0050] After the concrete reaches the demolding time, the construction personnel reversely operate, loosen the locking nut 5 and the adjusting nut 6, pull out the screw rod 4, remove the connection of the main connecting body and the formwork 2, detach the adjustable connecting member from the wall body, and clean and maintain, so as to be used in subsequent construction.

[0051] The above specific embodiments further specifically explain the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model, and is not used to limit the protection scope of the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
