Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a supporting structure for adding floors to a house. Background Art

[0002] With the accelerated pace of urbanization and the increasing scarcity of urban land resources, adding floors to existing buildings has become a crucial approach to improving land use efficiency and addressing housing needs. However, adding floors to a building is more than simply adding floors; it involves complex considerations such as structural safety, stability, and seismic performance. Traditional methods for adding floors often rely on rigid connections, directly adding new load-bearing structures such as steel columns and beams on top of the existing building structure to support the additional floors. While this approach meets the need for adding floors to a certain extent, it has numerous drawbacks.

[0003] First, rigid connections lack sufficient adaptability and buffering capacity. When adding floors to a building, the added floors impose additional loads on the existing structure, which often cause slight structural deformations during the transfer process. Traditional rigid connections are unable to effectively cope with these deformations, leading to internal stress concentrations and increasing the risk of structural failure. Especially under the influence of natural factors such as earthquakes and wind, rigid connections are more likely to cause increased structural vibration, compromising the building's stability and safety.

[0004] Secondly, traditional floor-adding renovation methods require high construction precision. Because rigid connections lack flexibility, even the slightest construction error can lead to uneven stress distribution, compromising overall stability. Consequently, strict quality control is required at every stage of the construction process, increasing both difficulty and cost. Utility Model Content

[0005] In response to the above problems, the purpose of the present invention is to provide a support structure for adding floors to a house, which solves the problems that traditional support structures for adding floors lack sufficient adaptability and buffering capacity, easily lead to increased structural vibration, and the construction difficulty and cost are highly affected by construction errors.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a support structure for adding a floor to a house, including a buffer frame, the upper and lower ends of the buffer frame are inserted into the top frame and the bottom frame, the top frame and the bottom frame are both composed of end plates and positioning plates welded together, the top frame is connected to one end of the screw in the adjustment member, the bottom frame is provided with a through slot for inserting the screw, the screw is threadedly connected with a nut, a pad is set on the screw between the nut and the bottom surface of the bottom frame, the bottom surface of the bottom frame is connected to a connecting frame, and the connecting frame is installed on the top of the steel column.

[0007] The beneficial effects of the present invention are as follows: when the upper layer plate is subjected to external forces, such as vibration caused by earthquakes or wind loads, the buffer frame absorbs and disperses the force on the top frame, reducing the direct impact on the steel columns. At the same time, the buffer frame under the pre-tightening force of the adjustment part can maintain a certain rigidity, providing necessary support for the upper layer plate.

[0008] In order to ensure the support stability of the buffer frame;

[0009] As a further improvement of the above technical solution: the buffer frame is composed of three buffer plates arranged around the axis of the screw, and the buffer plates are elastic arc-shaped steel plate structures.

[0012] As a further improvement of the above technical solution: the end plate is welded to the positioning plate, and the positioning plate is provided with a groove body adapted to be matched with the end of the buffer plate.

[0013] The beneficial effect of this improvement is that the upper and lower ends of the buffer plate can be clamped in the grooves provided on the positioning plate, thereby ensuring the stability of the installation of the buffer plate.

[0014] In order to avoid structural interference between the screw and the base frame when the buffer plate produces elastic deformation;

[0015] As a further improvement of the above technical solution: the difference between the inner diameter of the through slot and the diameter of the screw is not less than 1 cm, the top surface of the pad is a spherical structure, and the bottom surface is a flat structure.

[0016] The beneficial effect of this improvement is that the pad can be connected to the bottom surface of the base frame through a spherical support, ensuring that there is a certain movable gap between the screw and the base frame to meet the buffer tilting requirements of the top frame.

[0017] In order to conveniently tighten the nut;

[0018] As a further improvement of the above technical solution: the connecting frame is composed of vertical plates arranged on both sides of the screw and horizontal plates welded to the bottom of the vertical plates.

[0019] The beneficial effect of this improvement is that the connecting frame ensures the stability of the connection between the steel column and the base frame while avoiding affecting the tightening of the nuts by personnel.

[0020] In order to ensure the stability of the connection between the top frame and the layer board;

[0021] As a further improvement of the above technical solution: a plurality of bolt hole structures are opened through the top frame.

[0022] The beneficial effect of this improvement is that the provision of the bolt holes enables the top frame to be stably connected to the layer plates through bolts.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-3 shows: a support structure for adding floors to a house, including a buffer frame 1, the upper and lower ends of the buffer frame 1 are inserted into the top frame 2 and the bottom frame 3, the top frame 2 and the bottom frame 3 are both welded by end plates 21 and positioning plates 22, the top frame 2 is connected to one end of the screw 61 in the adjustment member 6, the bottom frame 3 is provided with a through slot 31 for inserting the screw 61, the screw 61 is threadedly connected with a nut 63, a pad 62 is set on the screw 61 between the nut 63 and the bottom surface of the bottom frame 3, and the bottom surface of the bottom frame 3 is connected to the bottom surface of the bottom frame 3. The connecting frame 4 is connected and installed on the top of the steel column 5. When the upper layer is subjected to external force, such as vibration caused by earthquake or wind load, the buffer frame 1 absorbs and disperses the force of the top frame 2, reducing the direct impact on the steel column 5. At the same time, the buffer frame 1 under the preload force of the adjustment member 6 can maintain a certain rigidity and provide necessary support for the upper layer. The buffer frame 1 is composed of three buffer plates 11 arranged around the axis of the screw 61. The buffer plate 11 is an elastic arc-shaped steel plate structure. The three rings The buffer plate 11 arranged around it can be evenly stressed, providing stable and reliable buffer support for the top frame 2 and the upper layer plate. The end plate 21 is welded to the positioning plate 22. The positioning plate 22 is provided with a groove body adapted to the end of the buffer plate 11. The upper and lower ends of the buffer plate 11 can be clamped in the groove body opened on the positioning plate 22 to ensure the stability of the installation of the buffer plate 11. The difference between the inner diameter of the through-slot 31 and the diameter of the screw 61 is not less than 1 cm. The top surface of the pad 62 is a spherical structure and the bottom surface is a flat structure. The plate 62 can be connected to the bottom surface of the base frame 3 through a spherical support to ensure that there is a certain movable gap between the screw 61 and the base frame 3 to meet the buffering tilt of the top frame 2. The connecting frame 4 is composed of vertical plates 41 arranged on both sides of the screw 61 and horizontal plates 42 welded to the bottom of the vertical plates 41. The connecting frame 4 ensures the stability of the connection to the steel column 5 and the base frame 3 while avoiding affecting the personnel tightening the nut 63. A plurality of bolt hole structures are opened through the top frame 2. The setting of the bolt holes enables the top frame 2 to be stably connected to the layer plate through bolts.

[0031] The working principle of this technical solution is: according to the construction error between the steel column 5 and the layer plate, the nut 63 is screwed to move the nut 63 toward the top of the screw 61, thereby reducing the distance between the bottom frame 3 and the top frame 2. At this time, the buffer plate 11 generates elastic energy storage; when the top surface height of the top frame 2 is adjusted to a suitable support height, the top frame 2 and the layer plate are connected by welding or bolts, and then the bottom end of the steel column 5 is fixed; when the layer plate vibrates, the buffer plate 11 generates elastic deformation, which plays the role of absorbing energy and buffering the connection between the layer plate and the steel column 5.
