Description

Technical Field

[0001] The utility model belongs to the technical field of seismic isolation trench cover plates, in particular to a building seismic isolation trench cover plate. Background Art

[0002] With the continuous advancement of construction technology, people's requirements for building safety are getting higher and higher. Especially in areas where earthquakes occur frequently, building seismic isolation technology has received widespread attention. As one of the seismic isolation measures, seismic isolation trenches set a certain depth of trench in the foundation and use the flexible material in the trench to absorb and alleviate the energy of seismic waves, thereby reducing the impact of earthquakes on buildings.

[0003] However, in actual applications, in order to ensure the waterproof effect of the seismic isolation trench, the traditional cover plate design needs to be higher than the outdoor ground. In this way, a step will be formed between the cover plate and the outdoor ground. Such a design will bring obvious inconvenience in public places such as hospitals or schools.

[0004] For hospitals, it is inconvenient for patients to walk, especially those with limited mobility. The presence of steps not only increases the difficulty of their walking, but may also cause them to fall, increasing safety risks. For wheelchair users, steps are even more insurmountable obstacles, seriously affecting their travel. In schools, active students can easily fall when running and playing, increasing the chance of accidents. If the height of the traditional cover is directly lowered during construction, it is easy for rainwater to penetrate into the seismic isolation trench. Utility Model Content

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] Example

[0024] The seismic isolation trench cover of the present embodiment is as follows: Figures 1 to 6As shown, it includes several bottom plates 1 distributed in sequence from front to back, a fixed block 2 is fixed on the left side of the bottom of the bottom plate 1, a second waterstop 3 is connected to the bottom of the fixed block 2, a top plate 4 independent of each other is arranged at the joint of the tops of each two adjacent bottom plates 1, a first waterstop 5 is connected to the front side wall of the top plate 4, and the first waterstop 5 and the second waterstop 3 are both made of rubber material; during production, the top plate 4 is cast by reinforced concrete, and during the casting process, the first waterstop 5 is connected to the front side wall of the top plate 4 through the first connecting block, and the cross-section of the first connecting block is a "convex"-shaped structure, and the first waterstop 5 and the first connecting block are of an integrally formed structure, and are both made of rubber material; the bottom plate 1 and the fixed block 2 are cast in one piece, and during the casting process, the second waterstop 3 is connected to the bottom of the fixed block 2 through the second connecting block, and the second waterstop 3 and the second connecting block are integrally formed, and are both made of rubber material;

[0025] The top of the bottom plate 1 is provided with a positioning groove; the bottom of the top plate 4 is fixed with two positioning blocks distributed front and back, the positioning block located on the rear side is arranged in the positioning groove located on the rear bottom plate 1, and the positioning block located on the front side is arranged in the positioning groove located on the front bottom plate 1; the front and rear bottom plates 1 here refer to the two bottom plates 1 adjacent to each other, and the two positioning blocks are flush with the front and rear side walls of the top plate 4 respectively; the width of the positioning block is equal to half of the width of the positioning groove. When in use, the top plate 4 is located at the joint between the tops of the two bottom plates 1, so that rainwater can be blocked from entering the vibration isolation groove from the joint, and the front side walls of each top plate 4 are connected with a first waterstop 5 to prevent rainwater from entering between the two adjacent top plates 4, and when the two positioning blocks are both located in the positioning groove, the sum of the widths of the two is equal to the width of the positioning groove, so that the two adjacent top plates 4 are pressed against each other, the first waterstop 5 is squeezed to prevent rainwater from entering (specifically as Figure 2 and Figure 6 shown).

[0026] like Figure 4 and Figure 5 As shown, a caulking plate is provided on the right side of the top of the top plate 4; the caulking plate includes a rubber pad 6, the top of the rubber pad 6 is an arc surface, the arc center of the arc surface is located below the rubber pad 6, and a steel plate 7 is fixed to the bottom of the rubber pad 6 to increase its bearing capacity; during production, a groove is opened at the bottom of the rubber pad 6, and the steel plate 7 is fixed in the hook groove to increase the bearing capacity of the rubber pad 6. During installation, the rubber pad 6 and one side of the steel plate 7 are laid on the top of the top plate 4, and the other side is laid on the outdoor ground. The right side of the rubber pad 6 is fixed to the outdoor ground (such as a speed bump on the road) by steel nails or expansion screws, and the left side of the rubber pad 6 can be sealed and connected with a flexible sealing material, such as asphalt and other materials, to achieve the purpose of waterproofing;

[0027] like Figure 4As shown, during the construction process, an installation groove is preset on the side wall of the building, that is, below the indoor floor. During installation, the left end of the base plate 1 is fixed in the installation groove by the fixing block 2, and the right end is placed on the top of the retaining wall and sealed by a flexible sealing material. This connection method mainly plays a waterproof role, and there is no fixed relationship between the base plate 1 and the retaining wall; the top of the top plate 4 is flush with the outdoor ground and at the same time flush with the indoor ground, thus eliminating the steps caused by the cover plate and improving the safety and convenience of public places (schools and hospitals). A step groove is opened between the retaining wall and the outdoor ground. The right sides of the bottom plate 1 and the top plate 4 are both located in the step groove, so that the top of the top plate 4 can be flush with the outdoor ground. A transition gap is left between the right sides of the bottom plate 1 and the top plate 4 and the step groove, which is used for the movement of the bottom plate 1 when the building shakes during an earthquake; the rubber pad 6 and the steel plate 7 are set above the transition gap to seal the transition gap, which is not only for aesthetics, but also to prevent people from tripping over the transition gap, and at the same time can prevent rainwater from entering the transition gap to a certain extent.
