Description

Technical Field

[0001] This invention belongs to the field of building decoration technology, specifically relating to a double-sided decorative structure for settlement joints and its construction method. Background Technology

[0002] After the building structure is completed, the building structure will not be modified. However, in special circumstances, the existing building can be partially modified to ensure its normal use. The construction of double-sided decorative structure on the outside of the building greatly increases the construction difficulty, especially in the location with settlement joints. It is necessary not only to ensure that the building can settle freely, but also to ensure its decorative effect.

[0003] Traditional decorative structure construction involves removing the existing decorative walls and then carrying out work both inside and outside. During construction, the existing building is out of use until completion, disrupting normal operation. Furthermore, all furniture and equipment at the construction sites must be removed and moved to other locations, and then relocated after completion, increasing both time and financial investment.

[0004] The current construction procedure for settlement joints involves disconnecting the keel at the settlement joint, leaving a 10-20mm wide gap in the decorative wall panel, and then installing aluminum alloy covers. The disadvantages of installing pre-made aluminum alloy settlement joint covers are twofold: first, they don't match the material and color of the decorative wall panel, resulting in a poor decorative effect; second, the 10-20mm wide gap in the decorative wall panel will deform and warp over time, significantly affecting the aesthetics and losing its decorative effect.

[0005] Chinese patent CN114876145A discloses a decorative connection structure and construction method for settlement joints in buildings. The structure includes a connector connected to the exterior wall of structure A, and a decorative structure installed on the side of structure B near structure A and connected to the connector. The decorative structure slides with structure B along the X and Y axes. A settlement joint is formed between structure A and structure B, and the end of the connector away from structure A passes through the settlement joint and slides with the decorative structure along the X and Y axes. This patent is only applicable to outdoor building curtain walls, and the connection requires one end to be connected to the building and the other end to the curtain wall frame, placing high demands on the building structure and limiting construction scenarios. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a double-sided decorative structure for settlement joints, which can decorate the settlement joints of buildings. The present invention also provides a construction method for it, so as to achieve the effect of a double-sided decorative structure with single-sided construction.

[0007] The technical solution adopted by this invention to solve its technical problem is: The double-sided decorative structure of the settlement joint includes vertical keels parallel to the structural columns arranged on both the left and right sides of the settlement joint and horizontal keels parallel to the structural beams and the bottom structural slab. The vertical keels near the structural columns are connected to the structural columns through expansion bolts. Horizontal keels are fixedly arranged at intervals between adjacent vertical keels. The horizontal keels near the structural beams and the structural slab are respectively connected to the structural beams and the structural slab through expansion bolts. A telescopic system is arranged in the middle of the settlement joint. A petal bolt is arranged in the middle of the telescopic system. Both the left and right sides of the telescopic system are connected to the vertical keels through horizontal keels. Decorative wall panels are connected to the front and back sides of the vertical keels and the telescopic system through strip assemblies. Sound-absorbing rock wool is filled between the decorative wall panels and the horizontal keels.

[0008] Wherein: A number of angle codes are welded on the horizontal keels near the structural beams and the structural slab. The upper horizontal keel is fixed to the structural beam through an expansion bolt passing through the angle code. The lower horizontal keel is fixed to the structural slab through an expansion bolt passing through the angle code.

[0009] A number of angle codes are welded on the vertical keels near the structural columns. The expansion bolts pass through the angle codes and are fixed to the structural columns.

[0010] The telescopic system includes an inner sleeve and an outer sleeve. The inner sleeve is connected to the horizontal keel on one side of the settlement joint, and the outer sleeve is connected to the horizontal keel on the other side of the settlement joint.

[0011] The outer sleeve is integrally arranged in a U-shaped configuration. A screw rod is arranged on one side of the inner sleeve away from the horizontal keel. A notch is arranged in the middle of the outer sleeve to cooperate with the screw rod. The screw rod passes through the notch and is fixed through a fastening nut.

[0012] Notches are arranged on both the front and back sides of the inner sleeve and the outer sleeve to cooperate with the petal bolt. The petal bolt passes through the notch and is arranged perpendicular to the horizontal keel.

[0013] The strip assembly includes a one-way strip, a two-way strip and an irregular strip. The one-way strip is arranged on both the front and back sides of the vertical keel near the structural column and both the front and back sides of the outer sleeve and is fixed through a petal bolt. The two-way strip is arranged on both the front and back sides of the vertical keel away from the structural column through a petal bolt. The irregular strip is arranged on one side of the inner sleeve near the horizontal keel through a swivel screw.

[0014] Both ends of the irregular strip are vertically arranged card slots. The length of the card slot at the upper end of the irregular strip is greater than the length of the card slot at the lower end. The strip assembly is arranged in cooperation with the decorative wall panel. The strip assembly and the decorative wall panel are fixed through rivets.

[0015] The construction method of the double-sided decorative structure of the settlement joint includes the following steps: S1. Cut out the horizontal and vertical keels according to the dimensions of the settlement joint, structural column, structural beam and structural slab, and position the bolt holes in the structural column, structural beam and structural slab. Place the expansion bolts in the bolt holes and then fix the fixing brackets on the expansion bolts. S2. Weld vertical keels to the fixed angle brackets of the structural columns, and weld horizontal keels to the fixed angle brackets of the structural beams and structural slabs to form a square structure. S3. Weld vertical keels at intervals on the structural beams and structural slabs on both sides of the settlement joint, weld some horizontal keels on the vertical keels, place the expansion joint inside the settlement joint, and then weld it to the horizontal keels on the vertical keels. S4. Install the clip assembly on the vertical keel and expansion system, place the outer decorative wall panel in the clip assembly, and then use rivets to fix the decorative wall panel to the clip assembly from the inside to the outside. After installing a decorative wall panel, weld all the horizontal keels connected to this decorative wall panel, and install them in sequence until all the horizontal keels and the outer decorative wall panels are installed. S5. Fill the sound-absorbing rock wool into the gaps separated by the horizontal keel inside the decorative wall panel; S6. Place the inner decorative wall panel in the clip assembly, and fix the inner decorative wall panel to the clip assembly with rivets. Install in sequence until all the inner decorative wall panels are installed. S7. Acceptance test after installation.

[0016] In step S3, when welding some of the horizontal keels onto the vertical keel, a gap is left to accommodate the decorative wall panel.

[0017] The beneficial effects of this invention are: This invention allows for the installation of a double-sided decorative structure from one side of the building, ensuring both a secure installation and a decorative effect. Horizontal and vertical keels are welded together to form a robust grid structure. The expansion joint system installed within the settlement joint is also connected via welding and other methods. The reinforcement of the horizontal keel enhances the structural stability of the decorative structure during use. The expansion joint system is connected to the keels on both sides of the expansion joint. When the building moves, all structural changes within the expansion joint occur within the expansion joint itself, thus not affecting the movement of the settlement joint or the structural integrity of the buildings on either side. The slots on the expansion joint system allow the petal bolts and screws to move up and down along the slots, achieving the function of vertical expansion and contraction. This allows the inner and outer sleeves to move up and down with the settlement of the building, breaking the original construction method of settlement joints. It not only satisfies the decorative effect but also ensures that the settlement function is not affected. When installing the inner and outer decorative wall panels, the decorative wall panels and horizontal keel structures are installed sequentially from one side. This progressive construction sequence ensures the orderliness of the construction and the convenience of operation. The sound-absorbing rock wool can absorb sound and reduce noise. While not affecting the normal use of the existing building, it can also reduce the costs of moving, installing and protecting the original furniture and equipment, greatly shorten the construction cycle, and reduce the investment in machinery and construction platforms, thus lowering construction costs.
