Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a connecting structure for roofs with varying heights. Background Technology

[0002] In modern architecture, the design of multi-span roofs is becoming increasingly common to meet the spatial needs of different functional areas. However, how to achieve convenient, safe, and effective connectivity between multi-span roofs while ensuring structural stability and waterproofing performance has always been an important issue in the field of architectural design. Traditional connection methods often suffer from structural complexity, construction difficulties, and poor drainage, affecting the practicality and aesthetics of the building.

[0003] To overcome these shortcomings, some improved high-low span roof connection structures have emerged on the market, but these structures often still have some deficiencies. For example, drainage surfaces and walking surfaces are often mixed together, leading to poor drainage and easy water accumulation problems. This not only affects the normal use of the building but may also damage the roof structure and reduce the building's lifespan.

[0004] Furthermore, existing roof connection structures with varying heights also have shortcomings in the design of the step modules. Some step modules use excessively heavy materials, which not only increases construction difficulty but may also lead to excessive structural load, compromising the stability and safety of the building. At the same time, the drainage design of these step modules is often inadequate, easily causing water accumulation at the bottom and affecting their service life.

[0005] Therefore, it is necessary to design a connecting structure for the roof spanning different heights to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connecting structure for roofs with varying heights.

[0007] The technical solution of this utility model is: a connecting structure for high and low roof spans, including a roof entrance module located at an expansion joint and a step module for connecting the high and low roof spans; the roof entrance module and the step module are connected by a connecting module; both the bottom of the connecting module and the step module are provided with drainage spaces, and the drainage space of the connecting module is connected to the drainage space of the step module.

[0008] The connection module includes a connection plate; the bottom of the connection plate has a plurality of support columns evenly distributed along the length direction for suspending the connection plate, and each support column has a first drainage groove on its bottom surface.

[0009] The step module is a precast lightweight reinforced concrete elephant eye step.

[0010] The step module includes a staircase and symmetrically arranged support bases at the bottom of the staircase; one end of the support base is connected to the bottom of the staircase, and the other end is connected to the top of the staircase; the bottom surface of the support base has a plurality of second drainage grooves evenly distributed along the length direction; the bottom of the staircase has a plurality of third drainage grooves evenly distributed along the width direction.

[0011] The top of the staircase extends outward with a top surface that protrudes from the location of the top of the support base.

[0012] The connecting module and the step module are provided with parapet walls on their sides; one end of the parapet wall is connected to the entrance / exit module, and the other end extends to the high roof.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects: (1) This utility model cleverly designs the roof entrance module and the step module, and uses the connecting module to tightly connect them, which effectively solves the problem of inconvenience caused by the height difference between high and low roofs; users can easily and safely pass between high and low roofs without worrying about safety hazards and inconvenience caused by height changes; in addition, the bottom of the connecting module and the step module are provided with drainage space, and these drainage spaces are interconnected to form a complete drainage system; this design not only improves drainage efficiency and ensures that rainwater can be discharged quickly, avoiding the occurrence of water accumulation problems, but also further enhances the waterproof performance of the roof structure layer and extends its service life.

[0014] (2) The bottom support of the stairs and the stairs themselves in the step module of this utility model are equipped with drainage grooves. This design further refines the drainage structure, ensuring that rainwater can be discharged smoothly and avoiding corrosion and damage caused by water accumulation. At the same time, the top surface design of the stairs extending outward not only increases the passage space, but also provides an additional dripping area, further improving the drainage effect.

[0015] (3) Both the connection module and the step module of this utility model can be prefabricated, which reduces the complexity and workload of on-site construction and improves construction efficiency; at the same time, the use of prefabricated components is also conducive to quality control, ensuring the stability and safety of the structure.

[0016] (4) The side of the connecting module and the step module of this utility model is provided with a parapet wall top, which not only increases the aesthetics of the structure, but also provides additional protection. The design of the parapet wall top is not only closely connected with the entrance module and the high roof to form a complete building appearance, but also provides additional sunshade and wind protection functions, enhancing the practicality and comfort of the building.

[0023] (Example 1)

[0024] See Figures 1 to 3 This embodiment provides a connecting structure for roofs with varying heights, including a roof entrance module 1 located at an expansion joint and a step module 2 for connecting the roofs with varying heights. The roof entrance module 1 and the step module 2 are connected by a connecting module 3. Both the connecting module 3 and the step module 2 have drainage spaces at their bottoms, and the drainage space of the connecting module 3 is connected to the drainage space of the step module 2, thereby reducing the height difference.

[0025] Furthermore, the connecting module 3 includes a connecting plate 3-1; the bottom of the connecting plate 3-1 is evenly distributed with a plurality of support columns 3-2 for suspending the connecting plate 3-1 along the length direction, and each support column 3-2 has a first drainage groove 3-3 on its bottom surface.

[0026] Furthermore, the step module 2 is a precast lightweight reinforced concrete elephant-eye step, which reduces the complexity and workload of on-site construction and improves construction efficiency. At the same time, the use of precast components is also conducive to quality control, ensuring the stability and safety of the structure. This embodiment uses an elevated connecting plate and precast lightweight reinforced concrete elephant-eye steps, which are small in size and weight, and facilitate roof inspection and maintenance.

[0027] Furthermore, the step module 2 includes a staircase 2-1 and a support base 2-2 symmetrically arranged at the bottom of the staircase 2-1; one end of the support base 2-2 is connected to the bottom of the staircase 2-1, and the other end is connected to the top of the staircase 2-1; the bottom surface of the support base 2-2 is evenly distributed with several second drainage grooves 2-3 along the length direction; the bottom of the staircase 2-1 is evenly distributed with several third drainage grooves 2-4 along the width direction; the support base 2-2 at the bottom of the staircase 2-1 and the staircase 2-1 itself in the step module 2 are both provided with drainage grooves. This design further refines the drainage structure, ensures that rainwater can be discharged smoothly, prevents the sides of the components from being eroded by rainwater, and avoids corrosion and damage caused by water accumulation; at the same time, the design of the top surface 2-5 extending outward from the top of the staircase 2-1 not only increases the passage space, but also provides an additional drip area, further improving the drainage efficiency. At the same time, it provides reserved space for the building roof structural layer, facilitating the construction of various roof structural layers, such as flashing and insulation.

[0028] Furthermore, the top of the staircase 2-1 extends outward to form a top surface 2-5, which protrudes from the top of the support base 2-2, increasing the passage space and providing reserved space for the building roof structure layer, facilitating the construction of each roof structure layer. Additionally, drip edges are installed around the components to prevent rainwater from eroding them.

[0029] Furthermore, the connecting module 3 and the step module 2 are provided with a parapet wall 4 on their sides; one end of the parapet wall is connected to the entrance module 1, and the other end extends to the high roof, which not only increases the aesthetics of the structure, but also provides additional protection.
