Description

Technical Field

[0001] This utility model relates to the technical field of roof structures, and in particular to a waterproof double-T board roof. Background Technology

[0002] Double-T slabs, as a classic precast concrete component, are widely used in the roofing and flooring systems of large buildings such as industrial plants, warehouses, and shopping malls due to their excellent structural performance, large span coverage, and efficient construction speed. Traditional double-T slab roofs consist of multiple double-T slabs installed side-by-side, connected by joints between them.

[0003] However, this traditional connection method suffers from a long-standing technical problem that has remained unresolved: leakage at the joints. Currently, common methods for treating joints mainly rely on filling the joints with flexible materials such as sealant or asphalt-impregnated hemp fibers, or laying additional waterproof membrane over the joints. These methods have revealed numerous limitations in practical engineering applications:

[0004] Poor waterproofing durability: The sealing materials relied upon are susceptible to hardening, cracking, shrinkage, or peeling from the concrete substrate due to long-term exposure to the natural environment, such as ultraviolet radiation, temperature cycling, and ozone aging, leading to waterproofing failure. Repair cycles are short and maintenance costs are high.

[0005] Sensitive to structural deformation: Under the influence of wind loads, snow loads, temperature changes, and foundation settlement, the roof structure will undergo certain deflection and displacement. Traditional sealing materials are difficult to adapt to this dynamic deformation. Once the deformation exceeds its elastic limit, cracks will appear at the joints, forming water seepage channels.

[0006] Inadequate or missing drainage design: Most existing technologies focus on "blocking water" rather than "draining water." When rainwater accumulates on the roof or is driven by wind over the cover plate above the slab joints, water seeps into the joints. Due to the lack of an effective internal drainage mechanism, moisture accumulates in the joints, not only directly causing leakage but also potentially accelerating the deterioration of concrete and internal steel reinforcement due to long-term freeze-thaw cycles or the intrusion of harmful substances. Utility Model Content

[0007] This utility model aims to address the shortcomings of existing technologies by providing a waterproof double-T board roof.

[0008] To achieve the above objectives, this utility model adopts the following technical solution:

[0009] A waterproof double-T slab roof includes double-T slabs. Symmetrical butt joints are provided on the left and right sides of the top of the double-T slabs. The butt joints are "┓" shaped structures. The butt joints of two adjacent double-T slabs are connected by a snap-fit ​​seat. A T-shaped snap-fit ​​groove is provided at the middle of the bottom of the snap-fit ​​seat. The two butt joints are installed in the T-shaped snap-fit ​​groove. Arc-shaped guide surfaces are provided on the left and right sides of the snap-fit ​​seat. Semi-circular grooves are correspondingly opened on the left and right sides of the double-T slabs. The semi-circular grooves of the butt joint surfaces of two adjacent double-T slabs form a circular through hole, and a guide pipe is installed in the circular through hole. The upper end of the outer wall of the guide pipe is inserted through the hole.

[0010] Waterproof geotextile is installed on the inner wall of the T-shaped clamp groove, and the waterproof geotextile is wrapped around the two connecting parts.

[0011] The top of the card slot has two n-shaped rings.

[0012] The upper surface of the double T-shaped plate is provided with guide grooves on the left and right sides.

[0013] Several lifting rings are provided on the upper surface of the double T-shaped plate.

[0014] A reinforcing cross brace is provided between the inner sides of the two vertical columns of the double T-shaped plate.

[0015] The two vertical columns of the double T-shaped plate are equipped with connecting cross braces on their outer sides. One of the connecting cross braces has a mating protrusion at its end and the other connecting cross brace has a mating groove at its end. When two adjacent double T-shaped plates are connected, the mating protrusion is installed in the corresponding mating groove.

[0016] The bottom of the double T-shaped plate is provided with several stiffening ribs.

[0017] Several reinforcing ribs are pre-embedded inside the double T-shaped plate.

[0018] The beneficial effects of this utility model are: it can fundamentally improve the waterproof performance of the board joints, enhance its durability and reliability, strengthen the overall integrity of the roof structure, and facilitate construction and installation.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] A type of waterproof double-T board roofing, such as Figures 1 to 4 As shown, it includes a double T-shaped plate 1, a connecting piece 2, a snap-fit ​​seat 3, a T-shaped snap-fit ​​groove 4, an arc-shaped guide surface 5, a semi-circular groove 6, a guide pipe 7, a waterproof geotextile 8, an n-shaped ring 9, a guide trench 10, a lifting ring 11, a reinforcing cross brace 12, a connecting cross brace 13, a connecting protrusion 14, a connecting groove 15, a stiffening rib 16, and a reinforcing rib 17.

[0030] The double-T slab 1 is a double-T structure consisting of a top slab and two vertical columns. It is the main load-bearing and covering component of the roof.

[0031] The top of the double T-shaped plate 1 is symmetrically provided with connecting parts 2 on the left and right sides. The connecting parts 2 are “┓” shaped structures and are the basic components for connecting with and transmitting force to adjacent plates.

[0032] The mating parts 2 of two adjacent double T-shaped plates 1 are connected by a snap-fit ​​seat 3. The snap-fit ​​seat 3 has a T-shaped snap-fit ​​groove 4 at the bottom center, and the two mating parts 2 are installed in the T-shaped snap-fit ​​groove 4.

[0033] The T-shaped locking groove 4 is used to accommodate and lock the two "┓" shaped mating parts 2, forming a strong mechanical connection.

[0034] The left and right sides of the card holder 3 are provided with arc-shaped guide surfaces 5, which can guide rainwater that may seep into the board seam to the sides instead of letting it accumulate at the seam. Structurally guiding the water flow is the first line of defense against water damage.

[0035] Semi-circular grooves 6 are correspondingly formed on the left and right sides of the double T-shaped plate 1. The semi-circular grooves 6 on the mating surfaces of two adjacent double T-shaped plates 1 form a circular through hole, and a drainage pipe 7 is installed inside the circular through hole. The upper end of the outer wall of the drainage pipe 7 is through-hole, which can effectively drain away any water that may leak from the joint. This constitutes an active drainage system, which is the second and crucial waterproofing measure.

[0036] Waterproof geotextile 8 is installed on the inner wall of the T-shaped joint groove 4, and the waterproof geotextile 8 wraps around the two connecting parts 2. This increases the waterproof layer of the material, forming a third line of waterproof defense, further sealing the joint and preventing capillary seepage.

[0037] The top of the card holder 3 is equipped with two n-shaped rings 9, which facilitates hoisting and transportation during construction.

[0038] The upper surface of the double T-shaped board 1 has drainage grooves 10 on the left and right sides, which helps to quickly drain large areas of rainwater from the board surface, prevent water accumulation, and reduce the drainage pressure of the joints.

[0039] The upper surface of the double T-shaped plate 1 is provided with several lifting rings 11, which are the lifting points of the prefabricated components, facilitating construction.

[0040] A reinforcing cross brace 12 is provided between the inner sides of the two vertical columns of the double T-shaped plate 1, which enhances the structural rigidity and stability of the single double T-shaped plate 1.

[0041] Both vertical columns of the double T-shaped panel 1 are equipped with connecting cross braces 13 on their outer sides. One connecting cross brace 13 has a mating protrusion 14 at its end, and the other connecting cross brace 13 has a mating groove 15 at its end. When two adjacent double T-shaped panels 1 are connected, the mating protrusion 14 is installed in the corresponding mating groove 15. This enables adjacent double T-shaped panels 1 to be horizontally connected at the bottom, greatly improving the overall integrity and stability of the roof and allowing for better coordinated stress distribution.

[0042] The bottom of the double T-shaped plate 1 is provided with several stiffening ribs 16, which further enhances the structural strength and bending resistance of the plate.

[0043] Several reinforcing ribs 17 are pre-embedded inside the double T-shaped plate 1 to ensure the load-bearing capacity of the component.

[0044] This invention combines a triple waterproofing mechanism of structural flow guidance, active drainage, and material sealing, effectively solving the problem of leakage at board joints and ensuring high reliability.

[0045] This utility model uses the upper snap-fit ​​seat 3 and the lower connecting cross brace 13 to tightly connect a single double T-shaped plate 1 into an integral roof structure, which has better stress performance and structural stability.

[0046] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
