Description

Technical Field

[0001] The utility model belongs to the technical field of construction and relates to a decorative structure for deformation joints of buildings. Background Art

[0002] In order to prevent cracks or damage to buildings due to factors such as temperature changes, uneven foundation settlement and earthquakes, the building is pre-designed at deformation-sensitive parts and divided into several relatively independent units. The reserved gaps can ensure that the building has sufficient deformation space. This structural joint is called a deformation joint.

[0003] In order to hide the expansion joint, a Chinese patent discloses a expansion joint waterproof device [authorization announcement number is CN221422283U]. A third bolt is passed through the middle of the center cover plate, and a nut is fitted on the outer wall of the third bolt. A sliding rod is fixedly connected to the outer wall of the nut. A T-shaped groove is provided at one end of the base toward the sliding rod. The end of the sliding rod is inserted into the corresponding T-shaped groove and fixedly connected to a sliding column. The sliding rod is placed obliquely between the two bases.

[0004] During the installation of the above-mentioned expansion joint waterproofing device, since the cover plate covers the expansion joint and the sliding rod, and there is a small gap or no gap between the cover plate and the building base, the cover plate is blindly installed when being fixed to the sliding rod. The installer needs to constantly adjust the position of the sliding rod to align the hole on the sliding rod with the center hole of the cover plate, which is inconvenient to install. The same operation is also performed when connecting other sliding rods to the cover plate, which greatly reduces the installation efficiency. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to provide a decorative structure for building expansion joints that is easy to install.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a decorative structure for the deformation joint of a building, which is arranged on bases on both sides of the deformation joint, including a first base fixed on one of the bases, a second base fixed on the other base, a plurality of sliding rods sliding between the first base and the second base, and a cover plate arranged outside the deformation joint, the first base and the second base are located on the inner side of the cover plate, a connecting column is vertically provided at the middle of the sliding rod, the connecting columns located on different sliding rods are parallel to each other and are all rotatably connected to the same connecting rod, the connecting rod extends along the length direction of the deformation joint and is provided with a plurality of threaded holes, the cover plate is provided with a plurality of connecting holes arranged one-to-one corresponding to the threaded holes, and the cover plate is connected to the connecting rod by screws.

[0007] First, fix the first base and the second base on the base on both sides of the deformation joint, then slide several sliding rods between the first base and the second base, then rotate and connect several connecting columns to the same connecting rod, then align the connecting holes on the cover plate with the threaded holes on the connecting rod one by one, and finally connect the cover plate to the connecting rod with screws.

[0008] When connecting the connecting column and the connecting rod, the operating space is not blocked, which facilitates the connection of the connecting rod and the connecting column; since the connecting holes on the cover plate correspond one to one with the threaded holes on the connecting rod, it is easy to align the connecting holes with the threaded holes, which facilitates the connection of the cover plate to the connecting rod.

[0009] In the decorative structure of the deformation joint of the above-mentioned building, the connecting rod includes a left half rod and a right half rod that fit together, and a number of limit cavities and through holes connected to the limit cavities are provided between the left half rod and the right half rod, which are equal to the number of the connecting columns and arranged one-to-one. The connecting columns are passed through the through holes corresponding to them, and the connecting columns are provided with limit heads that rotatably fit in the limit cavities, and the outer diameter of the limit heads is larger than the aperture of the through holes.

[0010] Half of the limiting cavity and through hole are located in the left half rod, and the other half are located in the right half rod. When the left half rod and the right half rod are attached, a complete limiting cavity and through hole are formed. Since the connecting rod is divided into a left half rod and a right half rod, it is convenient to limit the limiting head in the limiting cavity. After installation, the left half rod and the right half rod can be fixedly connected. One optional fixing method is to fix the left half rod and the right half rod with bolts and nuts, and the position of the bolts on the connecting rod is staggered with the connection between the connecting column and the connecting rod.

[0011] Some threaded holes are arranged on the left half rod, and the remaining threaded holes are arranged on the right half rod. The threaded holes arranged on the left half rod and the threaded holes arranged on the right half rod are arranged alternately.

[0012] In the decorative structure of the above-mentioned building deformation joint, a first slide groove extending along the length direction of the deformation joint is provided on the first base, a second slide groove extending along the length direction of the deformation joint is provided on the second base, the slide rod extends obliquely along the width direction of the deformation joint, one end of the slide rod is provided with a first ball head slider slidingly fitted in the first slide groove, and the other end of the slide rod is provided with a second ball head slider slidingly fitted in the second slide groove, the width of the opening of the first slide groove is smaller than the outer diameter of the first ball head slider, and the width of the opening of the second slide groove is smaller than the outer diameter of the second ball head slider.

[0013] The first and second chute slots are positioned opposite each other, allowing the first and second ball sliders to be inserted from either end. When the width of the expansion joint changes, the first ball slider slides and rotates within the first chute slot, and the second ball slider slides and rotates within the second chute slot, ensuring that the cover plate remains in the same position.

[0014] In the above-mentioned building expansion joint decoration structure, a sealing strip extending along the length of the expansion joint is clamped on each of the first and second bases and pressed against the inner side of the cover plate to prevent water from entering the first and second chutes.

[0015] In the above-mentioned decorative structure for deformation joints of buildings, the sealing strip is provided with two sealing fins arranged opposite to each other, and the sealing fins are pressed against the inner side of the cover plate.

[0016] In order to prevent water from entering, a sealing ring is provided on the screw.

[0017] In the above-mentioned decorative structure of the building deformation joint, a waterstop is provided in the deformation joint, one end of the waterstop is pressed between the base and the first base, and the other end of the waterstop is pressed between the base and the second base.

[0018] Compared with the existing technology, the decorative structure of the building expansion joint has the following advantages:

[0019] When connecting the connecting column and the connecting rod, the operating space is not blocked, which facilitates the connection of the connecting rod and the connecting column; since the connecting holes on the cover plate correspond one to one with the threaded holes on the connecting rod, it is easy to align the connecting holes with the threaded holes, which facilitates the connection of the cover plate to the connecting rod.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 The decorative structure of the building deformation joint shown is arranged on the base 1 on both sides of the deformation joint, including a first base 2 fixed on one of the bases 1, a second base 3 fixed on the other base 1, a plurality of sliding rods 4 sliding between the first base 2 and the second base 3, and a cover plate 5 covering the outside of the deformation joint. The first base 2 and the second base 3 are located on the inner side of the cover plate 5, and also includes a waterstop 16. One end of the waterstop 16 is pressed between the base 1 and the first base 2, and the other end of the waterstop 16 is pressed between the base 1 and the second base 3.

[0027] like Figure 2 and Figure 3 As shown, a connecting column 6 is vertically provided in the middle of the sliding rod 4. The connecting columns 6 located on different sliding rods 4 are parallel to each other and are all rotatably connected to the same connecting rod 7. The connecting rod 7 extends along the length direction of the deformation joint and is provided with a plurality of threaded holes 8. The cover plate 5 is provided with a plurality of connecting holes arranged one-to-one corresponding to the threaded holes 8. The cover plate 5 is connected to the connecting rod 7 by screws 9.

[0028] During installation, first fix the first base 2 and the second base 3 on the base 1 on both sides of the deformation joint, then slide several sliding rods 4 between the first base 2 and the second base 3, then rotate several connecting columns 6 to connect with the same connecting rod 7, then align the connecting holes on the cover plate 5 with the threaded holes 8 on the connecting rod 7 one by one, and finally connect the cover plate 5 to the connecting rod 7 with screws 9.

[0029] When connecting the connecting column 6 with the connecting rod 7, the operating space is not blocked, which facilitates the connection of the connecting rod 7 with the connecting column 6; since the connecting holes on the cover plate 5 correspond one-to-one with the threaded holes 8 on the connecting rod 7, it is easy to align the connecting holes with the threaded holes 8, which facilitates the connection of the cover plate 5 to the connecting rod 7.

[0030] like Figure 3 and Figure 4 As shown, the connecting rod 7 includes a left half rod 71 and a right half rod 72 that fit together. A number of limit cavities 10 equal in number to the connecting columns 6 and arranged one-to-one are provided between the left half rod 71 and the right half rod 72, and through holes 11 connected to the limit cavities 10. The connecting columns 6 are inserted into the corresponding through holes 11, and a limit head 12 is provided on the connecting column 6 to rotate in the limit cavity 10. The outer diameter of the limit head 12 is larger than the aperture of the through hole 11.

[0031] Half of the limiting cavity 10 and the through hole 11 are located in the left half rod 71, and the other half of the limiting cavity 10 and the through hole 11 are located in the right half rod 72. When the left half rod 71 and the right half rod 72 are fitted together, a complete limiting cavity 10 and through hole 11 are formed. Since the connecting rod 7 is divided into the left half rod 71 and the right half rod 72, it is convenient to limit the limiting head 12 to the limiting cavity 10. After installation, the left half rod 71 and the right half rod 72 can be fixedly connected. One optional fixing method is to fix the left half rod 71 and the right half rod 72 with bolts and nuts, and the position of the bolts on the connecting rod 7 is staggered from the connection between the connecting column 6 and the connecting rod 7.

[0032] Some of the threaded holes 8 are set on the left half rod 71, and the remaining threaded holes 8 are set on the right half rod 72. The threaded holes 8 set on the left half rod 71 and the threaded holes 8 set on the right half rod 72 are arranged alternately.

[0033] like Figure 1 As shown, the first base 2 is provided with a first slide groove extending along the length direction of the deformation joint, the second base 3 is provided with a second slide groove extending along the length direction of the deformation joint, the slide rod 4 is obliquely extended along the width direction of the deformation joint, one end of the slide rod 4 is provided with a first ball head slider 13 slidingly fitted in the first slide groove, and the other end of the slide rod 4 is provided with a second ball head slider 14 slidingly fitted in the second slide groove. The width of the first slide groove opening is smaller than the outer diameter of the first ball head slider 13, and the width of the second slide groove opening is smaller than the outer diameter of the second ball head slider 14.

[0034] The first and second chute grooves are arranged opposite each other, and the first and second ball head sliders 13 and 14 can be inserted from both ends of the first and second chute grooves. When the width of the expansion joint changes, the first ball head slider 13 slides and rotates in the first chute groove, and the second ball head slider 14 slides and rotates in the second chute groove, ensuring that the position of the cover plate 5 remains unchanged.

[0035] like Figure 1 As shown, a sealing strip 15 extending along the length of the deformation joint is clamped on both the first base 2 and the second base 3. The sealing strip 15 is pressed against the inner side of the cover plate 5 to prevent water from entering the first chute and the second chute. Figure 1 As shown, the sealing strip 15 has two sealing fins arranged opposite to each other, and the sealing fins are pressed against the inner side of the cover plate 5.

[0036] In order to prevent water from entering, a sealing ring is provided on the screw 9.
