Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, specifically relating to a ground foundation for prefabricated buildings and its construction method. Background Technology

[0002] Prefabricated construction refers to a construction method in which building components, modules, or entire structures are industrially produced and prefabricated in factories or prefabrication bases, and then transported to the site for assembly and installation. Compared with traditional on-site construction, prefabricated construction offers higher project quality, shorter construction cycles, and lower construction costs.

[0003] With its development in recent years, prefabricated construction has become increasingly widely used, capable of constructing various types of buildings such as residential, commercial, office, hotel, and school buildings. Their components or modules are typically prefabricated in factories, including wall panels, beams, columns, floor slabs, doors, and windows. These components undergo quality control in the factory and are produced efficiently using advanced production equipment and technology.

[0004] Once the prefabricated components or modules are completed, they are transported to the site for assembly and installation. Prefabricated construction offers several advantages: Accelerate construction speed: Since prefabricated components or modules are produced in factories, the time spent on the construction site can be greatly reduced, thereby accelerating the construction speed.

[0005] Improved construction quality: Prefabricated components or modules in factories can be subject to stricter quality control, and the quality of prefabricated buildings is easier to guarantee compared to traditional on-site construction.

[0006] Reduce construction noise and environmental impact: As construction time is reduced, noise and disturbance to the surrounding environment will also be reduced.

[0007] Conserving resources and energy: Prefabricated buildings typically employ industrialized production and prefabrication technologies, which can reduce material waste and save energy during construction.

[0008] Because of the aforementioned advantages of prefabricated buildings, they are more advantageous than traditional construction methods in the secondary construction and auxiliary building construction within factories, large exhibition halls, and other buildings, such as independent exhibition halls within large exhibition halls, and on-site offices or inspection rooms separated within factory workshops. Summary of the Invention

[0009] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a ground foundation for prefabricated buildings and its construction method. This invention is suitable for constructing auxiliary buildings inside workshops or large exhibition halls / exhibition centers. It features short construction time, low noise, and better protection of the construction site environment. During construction, it does not affect the normal use of other functional areas in the workshop or exhibition center.

[0010] The technical solution adopted by this invention to solve the problems existing in the prior art is: A ground foundation for a prefabricated building includes connectors, longitudinal beams, transverse beams, and a floor.

[0011] The longitudinal beams and transverse beams are arranged perpendicularly and intersecting each other, and the intersections of the longitudinal beams and transverse beams are fixedly connected by connectors.

[0012] Several spaced-apart crossbeams are placed above several spaced-apart longitudinal beams, with a floor sandwiched between two adjacent crossbeams.

[0013] Preferably, both the longitudinal beams and the transverse beams are made of tubing with a rectangular cross-section.

[0014] Preferably, the connector includes a rectangular tube with open ends, and two vertically arranged clamps are fixed to the top surface of the rectangular tube.

[0015] The longitudinal beam passes through the rectangular tube, and the transverse beam is sandwiched between two clamping plates.

[0016] Preferably, the outer side of the clamping plate is provided with a horizontally arranged partition, which provides support for the floor.

[0017] Preferably, a base is fixed below the rectangular tube.

[0018] Preferably, both ends of the longitudinal beam and both ends of the transverse beam are connected to end bases, and the four end bases surround a closed rectangular frame.

[0019] Preferably, the end base is a rectangular box with an open top, and an end insertion cavity is fixed inside the end base. The two ends of the longitudinal beam and the two ends of the transverse beam are respectively inserted into the corresponding end insertion cavity.

[0020] Preferably, the end base is covered with a top cover, and the end base is vertically provided with a wall panel column fixing tube, the top of which extends to the top of the top cover.

[0021] A construction method for the ground foundation of a prefabricated building includes the following steps: S1. A number of connectors equal to the number of crossbeams are fitted onto a single longitudinal beam, and the longitudinal beam passes through a rectangular tube; S2. Insert both ends of the longitudinal beam into the end bases on both sides respectively, and fix the two together. S3. Place the end base connected to one end of the crossbeam into position, placing it at the ends of the two end bases connected to the longitudinal beam, aligning or pre-connecting them for positioning. S4. Move the connector on the longitudinal beam to align with the crossbeam, and then snap the crossbeam between the clamps of the connector. S5. Fix the end of the crossbeam to its corresponding end base; S6. Install the floor between two adjacent beams, with the bottom surface of the floor abutting against the top surface of the partition. S7. Install the end base at the other end of the crossbeam, and then fix the adjacent end bases together.

[0022] Preferably, the ground foundation that has completed step S7 is moved and placed in a designated position, and then ballast material is filled into the end base. After the ballast material is filled, the top cover is installed.

[0023] Compared with the prior art, the present invention has the following beneficial effects: (1) The entire ground foundation is constructed by assembly, which is convenient, fast, noiseless and has little environmental pollution. During construction, it does not affect the normal use of other functional areas of the workshop, exhibition hall or exhibition hall.

[0024] (2) The ground foundation is fixed in position by weight, which mainly comes from the ballast material inside the end base. Therefore, it can be assembled in a convenient location, moved to the designated location after assembly, and then filled with ballast material to fix it in place. This is more flexible and suitable for site conditions under different environmental conditions. Attached Figure Description

Detailed Implementation

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this application belong. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application.

[0029] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for illustrative purposes and are determined based on the exemplary orientations shown in the accompanying drawings. Therefore, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0030] The following description, in conjunction with the accompanying drawings, provides a more detailed explanation of the ground foundation and construction method for a prefabricated building according to the present invention.

[0031] A ground foundation for a prefabricated building includes a connector 1, longitudinal beams 2, transverse beams 3, and a floor 7.

[0032] The longitudinal beam 2 and the transverse beam 3 are arranged perpendicularly and intersecting each other. The intersection of the longitudinal beam 2 and the transverse beam 3 is fixedly connected by the connector 1.

[0033] Several intermittently arranged horizontal beams 3 are set above several intermittently arranged longitudinal beams 2. That is, the keel of the ground foundation of the prefabricated building is divided into two layers. The upper layer consists of several intermittently arranged horizontal beams 3, and the lower layer consists of several intermittently arranged longitudinal beams 2. The two layers of intersecting keels can improve the overall strength and deformation resistance of the ground foundation.

[0034] For ease of assembly and fixing, both the longitudinal beam 2 and the transverse beam 3 are made of tubing with a rectangular cross-section. In this embodiment, square tubing is used directly, and aluminum alloy, magnesium alloy, or steel square tubing can be used.

[0035] A floor 7 is sandwiched between two adjacent crossbeams 3. The floor 7 can be supported by the longitudinal beams 2. If it is supported by the longitudinal beams 2, the thickness of the floor 7 will increase, at least to the same thickness as the crossbeams 3, which will increase the overall weight of the ground foundation and also increase the cost.

[0036] Therefore, in order to reduce the thickness of the floor 7 and thus reduce costs and weight, in this embodiment, the floor 7 is also supported by the connector 1.

[0037] To achieve this objective, in this embodiment, the connector 1 includes a rectangular tube 102 with open ends, two vertically arranged clamping plates 106 fixed on the top surface of the rectangular tube 102, the longitudinal beam 2 passing through the rectangular tube 102, and the transverse beam 3 clamped between the two clamping plates 106.

[0038] The outer side of the clamping plate 106 is provided with a horizontally arranged partition 107, which supports the floor 7.

[0039] A base 101 is fixed below the rectangular tube 102, and a rubber pad is fixed to the bottom of the base 101. The bottom of the rubber pad abuts against the floor of the factory, exhibition hall, or showroom. Therefore, the floor is also supported by the connecting piece 1 for the longitudinal beam 2 and the transverse beam 3.

[0040] The partition 107 effectively reduces the thickness of the floor 7. The longitudinal beams 2, transverse beams 3, and floor 7 are connected to several connectors 1 by interlocking, snap-fitting, and overlapping. Therefore, no tools are needed during the assembly of this part, and disassembly and assembly are very convenient and quick.

[0041] Both ends of the longitudinal beam 2 and both ends of the transverse beam 3 are connected to end bases 4. The four end bases 4 surround a closed rectangular frame, which forms the outline of the prefabricated building ground foundation and determines the ground space it occupies.

[0042] The end base 4 is a rectangular box with an open top. An end insertion cavity 402 is fixed inside the end base 4. The two ends of the longitudinal beam 2 and the two ends of the transverse beam 3 are respectively inserted into the corresponding end insertion cavity 402. To prevent the insertion cavity 402 from collapsing, a support rod 401 is provided at the bottom of the insertion cavity 402.

[0043] To further improve the reliability of the connection, an end cap 6 is inserted inside the insertion cavity 402. The end cap 6 includes a square tube 601, which is inserted into the insertion cavity 402. The side of the square tube 601 facing the inside of the ground foundation has an insertion hole 602, and the side facing the outside of the ground foundation has an end plate 603.

[0044] The ends of the longitudinal beam 2 and the transverse beam 3 are inserted into the insertion hole 602. The area of ​​the end plate 603 is larger than the area of ​​the insertion cavity 402, so it can be locked onto the outside of the end base 4 to serve as a limit. To prevent the end 6 from falling off, the end plate 603 can be fixedly connected to the end base 4 with bolts.

[0045] The end base 4 is covered with an upper cover 5, and the end base 4 is vertically provided with a wall panel column fixing tube 403 inside, with the top of the wall panel column fixing tube 403 extending through to the top of the upper cover 5.

[0046] The entire ground foundation can be assembled by fixing two adjacent end bases 4 together with angle iron and bolts at the connection points of the four end bases 4. Other positions do not need to be fixed, which can also ensure the stability of the entire ground foundation.

[0047] Furthermore, the ground foundation can be assembled directly at the installation location of the prefabricated building. If the area is not yet cleared or usable, the ground foundation can be assembled in another area first. After assembly, the entire ground foundation can be transported to the designated area by crane or other means. After the ground foundation is positioned, ballast material is filled into the end base 4 to increase the weight of the entire ground foundation, thus securing it with weight. After filling, the top cover 5 is placed on top. The filling material includes sand, metal blocks, metal particles, or directly poured cement.

[0048] In northern workshops, especially those built with corrugated steel panels, the interior temperature is low in winter. If the prefabricated buildings inside the workshop have specific temperature requirements, such as storing testing equipment where the testing temperature needs to be maintained above 20℃, or if the building serves as a rest area in the workshop and can provide warmth and improve worker comfort during winter, heat exchange plates 8 can be laid under the floor 7. The heat exchange plates 8 are inserted into the area between the partition 107 and the rectangular tube 102, abutting against the top surface of the rectangular tube 102. The heat exchange plates 8 can be electric heating plates; when powered on, they release heat to heat the floor 7, providing underfloor heating.

[0049] There will inevitably be gaps at the connection between beam 3 and floor 7. Sealing these gaps with sealant will release substances such as formaldehyde into the room, causing the building to remain hot for an extended period, affecting its usability. This is especially true for prefabricated buildings erected in exhibition halls, which need to be put into use as soon as possible; therefore, the use of sealant with an odor must be strictly avoided.

[0050] Meanwhile, during the building's use, floor 7 will definitely need to be cleaned and washed. Water from the cleaning process will flow along the gap between beam 3 and floor 7 onto the floor of the workshop or exhibition hall, making it even more difficult to handle.

[0051] To solve the above problems, in this embodiment, a first through hole 103 is provided on the wall of the rectangular tube 102, and a support plate 104 is fixed inside the rectangular tube 102 on both sides or above the first through hole 103. The support plate 104 divides the rectangular tube 102 into upper and lower regions. The upper region is the longitudinal beam insertion cavity 105, and the lower region is connected to the first through hole 103.

[0052] The longitudinal beam 2 passes through the longitudinal beam insertion cavity 105 and is supported by the support plate 104. A water receiving trough 9 with an open upper end is inserted inside the first through hole 103. The width of the water receiving trough 9 is greater than the width of the crossbeam 3. Therefore, the gap between the crossbeam 3 and the floor 7 is located directly above the water receiving trough 9.

[0053] Each horizontal 3 corresponds to a water receiving trough 9 below it. The ends of all water receiving troughs 9 are connected to the water collecting trough 10 through the through hole 1001 on the side wall of the water collecting trough 10. The water collecting trough 10 and the water receiving trough 9 are arranged perpendicular to each other and are fixedly connected by plugging.

[0054] A drain pipe 11 is connected to the end of the water collection tank 10. The drain pipe 11 is connected to the sewage collection bucket, and the sewage collection bucket can be cleaned in time.

[0055] A construction method for the ground foundation of a prefabricated building includes the following steps: S1. A number of connectors 1, equal to the number of crossbeams 3, are fitted onto a single longitudinal beam 2, and the longitudinal beam 2 passes through a rectangular tube 102. S2. Insert both ends of the longitudinal beam 2 into the end bases 4 on both sides respectively, and fix them together. S3. Place the end base 4 connected to one end of the crossbeam 3 into position, placing it at the ends of the two end bases 4 connected to the longitudinal beam 2, aligning or pre-connecting them for positioning. S4. Move the connector 1 on the longitudinal beam 2 to correspond with the cross beam 3, and then snap the cross beam 3 between the clamps 106 of the connector 1. S5. Fix the end of the crossbeam 3 to its corresponding end base 4; S6. Install the floor 7 between two adjacent crossbeams 3, with the bottom surface of the floor 7 abutting against the top surface of the partition 107; S7. Install the end base 4 at the other end of the crossbeam 3, and then fix the adjacent end base 4 in place.

[0056] S8. Move and place the ground foundation that has completed step S7 to the designated position, and then fill the end base 4 with ballast material. After filling the ballast material, install the top cover 5.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
