Description

Technical Field

[0001] This utility model relates to the field of roof expansion joint technology, specifically a roof expansion joint device for the skip-layer construction method of roof protective layer. Background Technology

[0002] Traditional construction techniques for expansion joints demand stringent precision and skill, aiming to ensure that the width, position, and depth precisely match design standards. Improper construction can easily compromise the effectiveness of the expansion joints, potentially leading to cracks in the roof protective layer and threatening the stability of the building structure. As a sensitive area of ​​the building, expansion joints are easily damaged by external environmental factors (such as wind, rain, and snow). Once damaged, the risk of leakage increases sharply, severely weakening the building's functionality and durability. Furthermore, to ensure the airtightness and waterproofing performance of the expansion joints, regular inspection and maintenance are essential, undoubtedly increasing the burden of post-construction maintenance. Simultaneously, the design of expansion joints must also consider architectural aesthetics, especially in building projects with stringent appearance requirements, where the layout and treatment of expansion joints require extra care. This invention proposes an expansion joint device for the skip-pour method of roof protective layer construction, which not only effectively isolates concrete blocks poured at different times but also reduces, to some extent, the cracking of concrete caused by factors such as temperature stress and shrinkage. This protective layer separation device, specifically designed for roof skip-construction, provides strong support for precise separation and protection during the construction process with its unique structure and superior performance.

[0031] The joint filler (3) is cut according to the thickness of the concrete protective layer 2 and the width and height of the left structure 4 and right structure (5) of the joint device. The cut joint filler (3) is then embedded in the gap between the left vertical connecting plate 44 and the right vertical connecting plate 56 below the lower corrugated connecting plate 54.

[0032] The left structure 4 of the expansion joint device, the right structure 5 of the expansion joint device, and the joint filling board 3 are combined to form an expansion joint device for the construction of the roof protection layer by skip-layer method. The device is embedded in the roof protection layer by positioning and laying out lines.

[0033] Both the left structure 4 and the right structure 5 of the partition joint device are made of aluminum alloy.

[0034] Example 1: During operation, the construction steps are as follows:

[0035] Step 1: Conduct measurement and positioning. First, based on the design drawings and the actual conditions of the construction site, accurately measure and locate the roof expansion joints. Next, on the base layer beneath the roof protective layer, clearly mark the locations of the roof expansion joints in both longitudinal and transverse directions using ink lines.

[0036] Step 2: Based on the dimensional data obtained from the measurement and positioning, the aluminum alloy components of the partition joint are precisely cut and prepared.

[0037] Step 3: Cut the joint filler plate 3 according to the cutting dimensions of the aluminum alloy partition assembly to ensure that its dimensions match the assembly.

[0038] Step 4: Combine the aluminum alloy expansion joint device assembly with the joint sealant 3 to form a complete roof protection layer expansion joint device system.

[0039] Step 5: Using a level, measure and determine the elevation positioning line of the roof according to the designed slope of the roof.

[0040] Step Six: Based on the concrete protective layer of the block determined in the construction plan, install the positioning and separation joint device (left side structure 4) precisely in its predetermined position at the boundary line of this block, according to the measured and positioned dividing line and elevation. Ensure that its elevation, slope, orientation, and planar position all meet the design requirements. During the pouring process, manually vibrate the area around the aluminum alloy separation joint device assembly to ensure the concrete is compacted, while avoiding under-vibration and over-vibration. During concrete pouring, special care must be taken to protect the anchoring groove at the top of the aluminum alloy separation joint device assembly to prevent it from being contaminated by concrete.

[0041] Step 7: After the poured concrete blocks have shrunk and stabilized (seven days after pouring), clean the construction joints and install the right-side structure 5 and sealant plate 3 of the expansion joint device. Pour the concrete, and during the pouring process, manually vibrate the area around the aluminum alloy expansion joint device assembly to ensure the concrete is compacted and to avoid under-vibration or over-vibration. During the concrete pouring process, special care must be taken to protect the corrugated cover plate on top of the aluminum alloy expansion joint device assembly from concrete contamination.

[0042] In summary, this device is prefabricated in the factory, easy to install, structurally robust, and aesthetically pleasing. Made of aluminum alloy, its application can significantly reduce or even eliminate roof cracking and leakage, thereby effectively lowering subsequent maintenance costs. This device not only effectively isolates concrete blocks poured at different times but also reduces the formation of cracks in concrete caused by temperature stress and shrinkage.
