Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a seismic-resistant structural node applied to indoor and outdoor entrances. Background Technology In the seismic design of indoor and outdoor entrances, the building basement adopts a reinforced concrete structure. Seismic isolation trenches are installed around the perimeter of the entire building's first floor, located on the outdoor outer side of the basement exterior walls. These trenches weaken the transmission of seismic energy, protect the building and surrounding facilities, and create the necessary conditions for the seismic isolation system to function effectively. Seismic isolation trenches can block the propagation of seismic waves, reduce the transmission of seismic energy to the building through the foundation soil, and lower the building's seismic response. In addition, rainwater gutters are generally installed outdoors. The function of rainwater gutters is to collect and drain rainwater, quickly removing accumulated water from the building roof or site surface to prevent safety hazards or structural damage caused by water accumulation. Rainwater gutters are generally located adjacent to the outer side of the seismic isolation trenches. After the basement roof structure is completed, the seismic isolation trenches and rainwater gutters are constructed using brick or block masonry. The cover plates of the seismic isolation trenches and rainwater gutters are generally located at the same outdoor ground level. Since the indoor ground level is higher than the outdoor ground level, a drainage ditch is installed above the cover plate of the seismic isolation trench to facilitate a transition between the indoor and outdoor ground levels.

[0002] Because the seismic isolation trenches and rainwater ditches are separated from the main building structure, including the basement, and are constructed in stages and in a secondary masonry manner, they have the following two main defects.

[0003] First, the brick-built rainwater ditch is not constructed as an integral part of the building structure. The side wall structure of the ditch is made of masonry, which has poor seismic performance and durability. At the same time, the masonry structure has weak waterproofing, requiring multiple additional waterproofing measures to meet the waterproofing requirements. However, in earthquake-prone areas, the durability and waterproofing of these additional waterproofing measures decrease rapidly due to the impact of earthquakes.

[0004] Secondly, during construction, the seismic isolation trench and the rainwater trench are constructed separately from the main building structure. The rainwater trench cover and the seismic isolation trench cover are aligned at the top elevation, which will result in a large height difference between the interface between the indoor and outdoor drainage and the outdoor ground level on the first floor. The large tilt angle is not conducive to use. Moreover, it is difficult to make the indoor and outdoor interfaces the same material, which is difficult to meet the design trend of consistency between the indoor and outdoor interfaces of buildings and the integration of landscape architecture in recent years. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an earthquake-resistant structure for indoor and outdoor entrances, which effectively ensures the earthquake resistance performance of indoor and outdoor entrances, improves the strength of the seismic isolation trench and rainwater trench, reduces the height difference between indoor and outdoor entrance surfaces, and maintains the uniformity of indoor and outdoor interfaces. The technical solution of this utility model is as follows: a seismic isolation trench and a rainwater trench are set around the perimeter of the first floor of the building. The rainwater trench is located on the adjacent outer side of the seismic isolation trench. One side of the seismic isolation trench is the basement structure of the building. The basement structure includes a basement roof beam, seismic bearings, and basement exterior walls. The seismic bearings are located between the upper basement roof beam and the lower basement exterior walls. The other side of the seismic isolation trench is a first side wall, and the bottom is a first base slab. The rainwater trench shares the first side wall with the seismic isolation trench. The rainwater trench also includes a second side wall and a second base slab. The first side wall, second side wall, first base slab, second base slab, and basement exterior walls are integrally reinforced concrete. The beam of the basement roof beam extends outward to the first floor cantilever slab of the building. The cantilever end of the first floor cantilever slab rests on the first side wall. The first floor cantilever slab serves as the top slab of the seismic isolation trench. The rainwater trench cover is set on the cantilever end of the first floor cantilever slab and the second side wall. A drainage system is provided on the upper part of the first floor cantilever slab.

[0006] Based on the above technical features: the drainage ditch and the rainwater ditch cover are hinged. Based on the above technical features: the gap between the first sidewall and the cantilevered end of the first floor slab of the building is filled and sealed with flexible waterproof material.

[0007] Based on the above technical features: a right-angled triangular steel is installed at the intersection of the rainwater ditch cover plate on the second side wall and the outdoor ground. The end of the rainwater ditch cover plate has an inwardly sloping cut, which corresponds to the inclined surface of the right-angled triangular steel. The bottom edge of the right-angled triangular steel is fixed to the second side wall.

[0008] The working principle of this utility model is as follows: The first sidewall, second sidewall, first floor slab, second floor slab, and basement exterior walls are rigidly connected by integral cast-in-place reinforced concrete, increasing strength. This underground structural system is separated from the above-ground building structure. During an earthquake, the above-ground building structure and the underground structural system can undergo relative displacement to resist large-scale seismic loads; simultaneously, the seismic isolation trench blocks the propagation of seismic waves, reducing the transmission of seismic energy to the building through the foundation soil; furthermore, the seismic isolation trench and the storm drain can withstand damage from small-scale seismic loads through their own structural strength.

[0009] Hinged connections are installed between the drainage ditch and the storm drain cover, and the storm drain cover is connected to the outdoor ground surface by a right-angled triangular steel oblique sliding connection, which can ensure that the indoor and outdoor ground can deform freely and reduce damage during an earthquake.

[0010] The beneficial effects of this utility model are as follows: The seismic-resistant structure of the indoor and outdoor entrances ensures seismic performance and effectively meets the seismic design requirements of buildings. The durability and waterproofness of the rainwater gutters are enhanced. In addition, the transition of ground elevation between the indoor and outdoor entrances is smoother and more consistent in appearance, which is more in line with the recent design trend of consistent indoor and outdoor interfaces and integrated landscape architecture.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0016] In the description of this utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 As shown, the seismic-resistant structure B for the indoor and outdoor entrances of this utility model can be applied to multi-story buildings with seismic resistance and isolation structural design requirements. The main building structure can be a reinforced concrete frame structure, including the above-ground building C and the basement A. The seismic-resistant structure B for the indoor and outdoor entrances is set around the perimeter of the first floor of the building. like Figure 2 and Figure 3 As shown, one side of the seismic isolation trench 1 is the basement structure of the building, which includes a basement roof beam 11, seismic bearings 4, and an exterior wall 12. The seismic bearings 4 are located between the basement roof beam 11 and the exterior wall 12. The other side of the seismic isolation trench 1 is a first sidewall 3-1, and the bottom is a first base slab 3-3. The rainwater ditch 2 shares the first sidewall 3-1 with the seismic isolation trench 1. The rainwater ditch 2 also includes a second sidewall 3-2 and a second base slab 3-4. Figure 2 As shown, the first base plate 3-3 and the second base plate 3-4 are at the same elevation and can be combined into a single plate; as Figure 3 As shown, the depths of the seismic isolation trench 1 and the rainwater trench 2 are different, and the first base plate 3-3 and the second base plate 3-4 may not be located at the same elevation.

[0018] The first side wall 3-1, the second side wall 3-2, the first base slab 3-3, the second base slab 3-4, and the basement exterior wall 12 are integrally reinforced concrete. Compared with the masonry structure in the prior art, the reinforced concrete structure here has better structural strength and water resistance, and is more suitable for the durability and water resistance requirements of building components in earthquake-prone areas.

[0019] like Figure 2 and Figure 3 As shown, the beam body of the basement roof beam 11 extends outwards to form the first-floor cantilever slab 5 of the building. The cantilever end of the first-floor cantilever slab 5 rests on the first side wall 3-1. The first-floor cantilever slab 5 serves as the top slab of the seismic isolation trench 1. The rainwater trench cover 6 of the rainwater trench 2 is installed at the cantilever end of the first-floor cantilever slab 5 and on the second side wall 3-2. A drainage ditch 7 is installed on the upper part of the first-floor cantilever slab 5, transitioning from the indoor floor level 9 to the rainwater trench cover 6. The rainwater trench cover 6 is located on the top slab of the seismic isolation trench 1. The second side wall 3-2 and the top of the first-floor cantilever slab 5 can be leveled, and then the rainwater trench cover 6 and the drainage ditch 7 are installed on top. Therefore, the rainwater trench cover 6 and the drainage ditch 7 can be installed at the same elevation, and the height difference between their surfaces is smaller after construction. Figure 2 As shown by the thick solid line, this structure makes the transition between indoor and outdoor spaces smoother, meeting the requirement of integrated indoor and outdoor space interfaces in architectural design.

[0020] like Figure 3 As shown, the gap between the first side wall 3-1 and the first-floor cantilever slab 5 of the building is filled and sealed with flexible waterproof material 8. Flexible waterproof material 8 can be polyurethane foam waterproof adhesive. Figure 2 The image shows the state of water in rainwater ditch 2. like Figure 4As shown, the apron 7 and the storm drain cover 6 are hinged and sealed with flexible waterproof material. Both the apron 7 and the storm drain cover 6 can be made of fine aggregate concrete 19 covered with plaza bricks 20. Angle steel 15 is used to encase the sides of the apron 7 at the hinge, and steel plates are used to encase the bottom and sides of the storm drain cover 6. Metal hinges 14 are installed between the angle steel 15 of the apron 7 and the sidewall steel plates 16 of the storm drain cover 6. The metal hinges 14 are existing, mature connecting components, and generally, at least two sets of metal hinges 14 are installed on each storm drain cover 6. The top of the hinge is covered with a stainless steel plate 17. The gap between the stainless steel plate 17 and the angle steel 15 is sealed with a flexible waterproof material 18, such as polyethylene foam rods and waterproof sealant.

[0021] like Figure 5 As shown, the rainwater ditch cover 6 on the second side wall 3-2 is connected to the outdoor ground 13 by a right-angled triangular steel 10. The end of the rainwater ditch cover 6 has an inwardly angled cut, corresponding to the inclined surface of the right-angled triangular steel 10. The bottom edge of the right-angled triangular steel 10 is fixed to the second side wall 3-2, and the other right-angled side of the right-angled triangular steel 10 is adjacent to the outdoor ground 13. The top gap between the rainwater ditch cover 6 and the right-angled triangular steel 10 is sealed with a flexible waterproof material 18.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
