Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a lightweight modular equipment base system. Background Technology

[0002] In construction projects, both large and small equipment require corresponding equipment bases. Equipment bases are mainly used to fix and support various types of equipment (such as air conditioning units, fans, solar panels, water tanks, etc.), and through reasonable design and installation, ensure the safe and stable operation of the equipment.

[0003] In building construction, the most common type of equipment base is a concrete base, typically strip-shaped or rectangular to accommodate various equipment installation dimensions. These bases need to protrude a certain height above the finished building surface to provide effective fixation, support, and load transfer for the equipment, preventing it from tipping over, being covered by snow, and damaging the roof's waterproofing and insulation layers during installation. Typically, equipment bases installed indoors protrude 200mm to 300mm above the finished building surface, while those installed on rooftops or other outdoor spaces protrude 200mm to 500mm. Because the finished roof structure includes thick roof insulation and cement mortar, the equipment base often protrudes 400mm to 800mm above the roof slab. Due to their large size and high concrete usage, construction costs are high, and their excessive weight can place additional loads on the main building structure, forcing reinforced designs of beams and columns, further increasing the overall cost. In addition, there is often a conflict between the construction sequence of traditional bases and equipment procurement: equipment bases need to be customized according to the size of the equipment, but in actual projects, equipment procurement often lags behind base construction, which can easily cause size deviations and affect installation efficiency; for long-term installation needs, reserved bases are not adjustable and can easily lead to mismatch between equipment and base.

[0004] Therefore, there is an urgent need for a lightweight, low-cost, flexible, and construction-compatible equipment base solution to solve the above problems. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a lightweight modular equipment base system that is lightweight, has vibration isolation performance, and is highly adaptable to building structures.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A lightweight modular equipment base system includes multiple equipment base units, each equipment base unit comprising:

[0008] A concrete base, a rectangular structure made of cast-in-place reinforced concrete;

[0009] Vibration isolators, the bottom of which is fixedly connected to the top of the concrete base;

[0010] The steel structure column base is fixedly connected to the top of the vibration isolator at its bottom, and the top is used for installing equipment.

[0011] Two parallel first-section steels are symmetrically connected to the two side walls of the column base of the steel structure along the transverse direction.

[0012] Two parallel second-section steel beams are symmetrically connected to the two longitudinal side walls of the column base of the steel structure.

[0013] The equipment base unit is connected to at least one adjacent equipment base unit through the first steel section or the second steel section, so that all the equipment base units form an integral frame.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, transverse node plates are welded to the transverse side walls of the steel structure column base, and the first steel section is connected to the steel structure column base through the transverse node plates; longitudinal node plates are welded to the longitudinal side walls of the steel structure column base, and the second steel section is connected to the steel structure column base through the longitudinal node plates.

[0016] Furthermore, the connection between the transverse node plate and the first steel section is by bolting, welding, or bolted welding; the connection between the longitudinal node plate and the second steel section is by bolting, welding, or bolted welding.

[0017] Furthermore, the steel structure column base is made of H-beams or I-beams, with a top plate welded to the top for equipment installation and a bottom plate welded to the bottom for connection with the vibration isolator.

[0018] Furthermore, the bottom of the vibration isolator is fixed to the top of the concrete base by bolts; the base plate of the steel structure column foot is fixed to the top of the vibration isolator by bolts.

[0019] Furthermore, the top plate forms a continuous coplanar structure with the upper surface of the first steel section and the upper surface of the second steel section.

[0020] Furthermore, in the equipment base units arranged laterally adjacent to each other in the horizontal plane, the connection method between two adjacent first steel sections is bolted connection, welding or bolted connection; in the equipment base units arranged longitudinally adjacent to each other in the horizontal plane, the connection method between the second steel sections of at least two adjacent units is bolted connection, welding or bolted connection.

[0021] Furthermore, the vibration isolator is a spring vibration isolator or a rubber vibration isolator.

[0022] Furthermore, the concrete base is poured on the main structural floor slab, and it uses the same grade of concrete as the main structural floor slab.

[0023] Furthermore, it also includes a third type of steel, through which partially parallel first type steels are connected to each other; and through which partially parallel second type steels are connected to each other.

[0024] The beneficial effects of this utility model are:

[0025] 1. This utility model replaces the traditional long or rectangular concrete base with a point-distributed concrete base. To accommodate the installation needs of various equipment shapes, a first and second type of steel are installed on the point-distributed concrete base to form a cross-shaped steel support. Each equipment base unit is connected to at least one adjacent equipment base unit via the first or second type of steel, thus forming an integral frame. This combination balances the base's load-bearing capacity and stability. This integral frame can replace the traditional long or rectangular concrete base, providing an effective mounting base for the equipment while reducing concrete usage, lowering the self-load of the concrete base, and reducing the overall cost of the equipment base system.

[0026] 2. This utility model installs a vibration isolator between a concrete base and a steel frame. Multiple devices mounted on the steel frame increase the overall counterweight. Increasing the counterweight is an effective means of suppressing equipment vibration. Its core principle is to reduce the resonance frequency by increasing the system inertia and blocking the transmission of vibration energy. This utility model can absorb vibration energy by utilizing the overall inertial force of the steel frame and the equipment. After the steel frame and steel structure column base are connected to the equipment by bolts, the counterweight of the vibrating equipment is increased, which can lower the vibration center of gravity and frequency, reduce the transmission of vibration to the concrete base, and effectively improve the vibration isolation effect on the equipment.

[0036] Example

[0037] A lightweight modular equipment base system includes multiple equipment base units, such as Figure 1-2 The equipment base unit shown includes a concrete base 1, a vibration isolator 4, a steel structure column base 2, a first steel section 31, and a second steel section 32;

[0038] The concrete base 1 is a cuboid structure made of cast-in-place reinforced concrete, including cast-in-place reinforced concrete, a waterproof layer and a cement mortar surface layer. It is poured on the main structural floor slab 7 and uses the same grade of concrete as the main structural floor slab 7.

[0039] The vibration isolator 4 is a spring vibration isolator 4 or a rubber vibration isolator 4, and its bottom is fixedly connected to the top of the concrete base 1 by bolts.

[0040] The steel structure column base 2 is made of H-beams or I-beams. The horizontal side walls of the column base 2 are welded with horizontal node plates 81, the vertical side walls are welded with vertical node plates 82, the top is welded with a top plate for installing equipment 6, and the bottom is welded with a bottom plate and fixedly connected to the top of the vibration isolator 4 by bolts.

[0041] Two parallel first steel sections 31 are symmetrically connected to the two side walls of the column of the steel structure column base 2 along the transverse direction; the transverse node plate 81 is connected to the first steel section 31 by connecting bolts 5, and the connection method can also be welding or bolted welding, and is connected to the steel structure column base 2 through the transverse node plate 81.

[0042] Two parallel second-section steels 32 are symmetrically connected to the two longitudinal side walls of the column base 2 of the steel structure; the longitudinal node plate 82 is connected to the second-section steels 32 by connecting bolts 5, and the connection method can also be welding or bolted welding, and is connected to the steel structure column base 2 through the longitudinal node plate 82.

[0043] like Figure 3 As shown, each equipment base unit is connected to at least one adjacent equipment base unit via the first steel section 31 or the second steel section 32, so that all the equipment base units form an integral frame. In the horizontally adjacent equipment base units, the connection between two adjacent first steel sections 31 can be a bolted connection, welded connection, or bolted connection; in the horizontally adjacent equipment base units, the connection between at least two adjacent second steel sections 32 can be a bolted connection, welded connection, or bolted connection.

[0044] In a preferred embodiment, the top plate forms a continuous coplanar structure with the upper surfaces of the first steel section 31 and the second steel section 32. The first steel section 31 and the second steel section 32 are perpendicular to each other to form a cross-shaped steel bracket for installing the equipment 6. The first steel section 31 is adapted to the equipment 6 in the transverse direction, and the second steel section 32 is adapted to the equipment 6 in the longitudinal direction. The first steel section 31 and the second steel section 32 are of relatively long lengths; the first steel section 31 must be longer than the transverse length of the equipment 6, and the second steel section 32 must be longer than the longitudinal length of the equipment 6. This effectively avoids the problem of the traditional concrete base 1 being installed but not matching the dimensions of the equipment 6, thus affecting the installation of the equipment 6.

[0045] In a preferred embodiment, such as Figure 4 As shown, it also includes a third type of steel 33, through which the partially parallel first type of steel 31 are connected to each other; and through which the partially parallel second type of steel 32 are connected to each other. The third type of steel 33 can be flexibly applied to the overall frame according to the needs of the equipment, and combined with the first type of steel 31 and the second type of steel 32 to form an independent equipment installation platform to adapt to different sizes and dimensions of the equipment.

[0046] The construction of this utility model shall be carried out according to the following steps:

[0047] 1. Prefabrication of equipment base unit: Concrete base 1 is poured on-site on the main structural floor slab 7. After curing, vibration isolators 4 are fixed to the top of the concrete base 1 with bolts. Subsequently, steel structure column base 2 is welded to the top and bottom slabs, and transverse and longitudinal node plates 82 are welded to the side walls of the column. Finally, the bottom plate of the steel structure column base 2 is connected to the top of the vibration isolator 4 with bolts to form an independent equipment base unit.

[0048] 2. Modular assembly: According to the layout requirements of equipment 6, multiple base units are arranged horizontally or vertically. Horizontally adjacent units are rigidly connected to the corresponding horizontal node plates 81 through the first steel section 31; vertically adjacent units are selectively connected to the vertical node plates 82 through the second steel section 32, ultimately forming an overall frame structure.

[0049] 3. Equipment 6 Installation: Place equipment 6 on the continuous plane formed by the top plate of the steel structure column base 2 and the upper surfaces of the first steel section 31 and the second steel section 32, and fix it with bolts to ensure that the load of equipment 6 is evenly transferred to the base system. If the equipment is large and a single equipment base unit cannot support the installation, the third steel section 33 acts on the overall frame, combined with the first steel section 31 and the second steel section 32, to form an independent equipment installation platform to accommodate the installation of the equipment.
