Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a transverse keel structure of an assembled wall. Background Art

[0002] The horizontal keel structure is a common form of building component in prefabricated walls. It is usually used in combination with the vertical keel structure. It mainly forms the internal frame of the prefabricated wall together with the vertical keel by horizontally fixing the vertical keel to support the wall structure.

[0003] At present, the common transverse keel structures on the market are mainly made of light steel with simple structures. Most of them are just stamped U-shaped plates, which generally only serve to connect and fix the vertical keel structure in the keel frame. In traditional transverse keel structures, there is usually no auxiliary installation structure on the keel structure. During on-site construction, it mainly relies on manual connection and fixation with other building components. The installation efficiency is low and the assembly quality is not ideal, especially the installation tightness requirements are difficult to guarantee. In addition, since the keel structure generally does not have a structural design for heat and sound insulation, it cannot produce beneficial effects in terms of sound insulation, heat insulation, and fire delay.

[0004] Therefore, it is necessary to propose a new transverse keel structure of the prefabricated wall, so as to improve the assembly efficiency and assembly quality of the transverse keel structure during the construction of the prefabricated wall, so as to obtain higher installation tightness. In addition, the functional requirements of the prefabricated wall such as fire delay, sound insulation and heat insulation also need to be improved. Utility Model Content

[0005] The utility model aims to provide a transverse keel structure of an assembled wall, which can improve the assembly efficiency and the assembly quality at the same time, so as to obtain higher installation tightness.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A transverse keel structure of an assembled wall, comprising a bottom plate and side plates extending together in a longitudinal direction, wherein the bottom plate is a strip-shaped plate member, and the side plates are two plates correspondingly arranged on opposite sides of the bottom plate, the bottom plate and the side plates are combined to form the transverse keel structure with a generally U-shaped transverse cross-section, the bottom plate has an upward plate surface protrusion structure extending along the longitudinal direction in its middle part in the transverse direction, the protrusion structure has a plurality of positioning structures matched with a fastening device, the bottom plate has step structures on both sides of the plate surface protrusion structure in the transverse direction, the step structures are suitable for making the plate surfaces of the side plates and the bottom plate tightly attached to the adjacent structural surfaces through structural deformation when the plate surface protrusion structure cooperates with the fastening device.

[0008] Furthermore, the panel surface protrusion structure has a partition structure, and the partition structure is configured to block the sound and heat transfer in the transverse keel structure and to concentrate the thermal deformation of the transverse keel structure.

[0009] Furthermore, the partition structure is a plurality of partition holes arranged along the longitudinal direction at certain intervals.

[0010] Furthermore, the partition hole is a long strip opening which is at a certain angle relative to the longitudinal direction.

[0011] Further, the plurality of positioning structures are positioning holes arranged along the longitudinal direction at certain intervals.

[0012] Furthermore, the side panels are flattened on the side away from the bottom panel.

[0013] Furthermore, the exposed side edges of the transverse keel structure are all in arc shape.

[0014] Furthermore, the transverse keel structure is made of light steel.

[0015] Furthermore, the transverse keel structure is integrally formed by a stamping process.

[0016] The beneficial effects of the utility model compared with the prior art are:

[0017] 1. The utility model provides a partition structure on the transverse keel structure of an assembled wall, which can achieve the effect of fire prevention and delay by controlling the deformation of the transverse keel structure when a fire occurs, thereby enhancing the safety of the structure. The partition structure can also help block the propagation of heat or sound, thereby improving the sound insulation, heat insulation and other effects of the assembled wall.

[0018] 2. The utility model provides a transverse keel structure for an assembled wall. Since the bottom plate has a raised plate surface structure in the middle of the bottom plate in the transverse direction, after the raised plate surface structure in the middle is locked by a fastening device (such as a screw), the bottom plates on both sides in the transverse direction (that is, the step structure) form a water stop platform that can fit better with the ground, thereby enhancing the anti-seepage function. At the same time, the wall panels on both sides also tend to retract after the raised plate surface structure in the middle is locked by the fastening device, thereby enabling the surface to fit more closely with adjacent components (such as vertical keel structures) or other structural surfaces during assembly and fixation, thereby having better assembly and sealing properties.

[0030] The detailed features and advantages of the present invention are described in detail in the specific implementation modes below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of the present invention and implement it accordingly. Moreover, according to the specification, claims and drawings disclosed in the present invention, the technical personnel in this field can easily understand the relevant purposes and advantages of the present invention.

[0031] The directional terms such as "up", "down", "side", "left", "right", "front" and "back" used in this article are used with reference to the conventional orientation of the transverse keel structure of the prefabricated wall during the installation process, while "longitudinal" and "transverse" are used with reference to the slender shape of the transverse keel structure itself, and should generally be considered as two perpendicular directions.

[0032] Figure 1 This is a side structural diagram of a transverse keel structure of an assembled wall according to an embodiment of the utility model. Figure 3 FIG. 1 is an overall schematic diagram of a transverse keel structure of an assembled wall according to an embodiment of the utility model after being assembled. Figure 1 and Figure 3As shown, the transverse keel structure 6 of this embodiment is composed of a side panel 1 and a bottom panel 2 extending together in the longitudinal direction, wherein the bottom panel 2 is located on the bottom surface of the transverse keel structure 6 and is a substantially rectangular strip-shaped plate, and the side panel 1 includes two plates symmetrically distributed on the front and rear sides of the bottom panel 2, and the two plates extend upward along the front and rear long sides of the bottom panel 2 respectively, and are combined with the bottom panel 2 to form a transverse keel structure 6 with a substantially U-shaped transverse cross section. The side panel 1 and the bottom panel 2 extend to a certain length in a direction perpendicular to the transverse cross section of the transverse keel structure 6, that is, in the longitudinal direction (left and right direction), so as to meet the assembly requirements during the installation of the transverse keel structure. It can be understood that the side panel 1 is not necessarily arranged in a symmetrical manner along the front and rear sides of the bottom panel 2, and the structural form of the front and rear side panels can be differentially adjusted according to structural requirements. At the approximately middle position in the transverse direction (front-rear direction) of the bottom plate 2, the plate surface of the bottom plate 2 is raised upward (i.e., in the same direction as the side plate extends from the bottom plate) to form a plate surface raised structure, so as to symmetrically form two step structures 3 on the front and rear sides of the bottom plate 2 (or on the transverse sides of the plate surface raised structure). On the plate surface raised structure of the bottom plate 2, there are a plurality of positioning holes 5 (i.e., positioning structures) evenly arranged at certain intervals along the longitudinal direction of the bottom plate 2, which are suitable for screws or other fastening devices to pass through during the on-site assembly process, and provide assistance for the installation and positioning of the transverse keel structure 6. It can be understood that the positioning holes 5 are not limited to the arrangement method of being evenly arranged at certain intervals, and the shape of the openings is not limited to a circle. The two step structures 3 are suitable for tightening the convex structure of the plate surface in the middle of the bottom plate 2 with screws, and utilizing the structural deformation stress generated during the tightening process to make the side plate 1 and the adjacent components (such as the vertical keel structure) or other structural surfaces (such as the wall panel surface) closer to each other, so as to achieve better assembly, and at the same time, make the bottom plate 2 and the adjacent components or structural surfaces (such as the ground) closer to each other, so as to achieve the effect of preventing water seepage. It can be understood that the step structure 3 is not necessarily arranged in a symmetrical manner along the front and rear sides of the bottom plate 2. The structural form along the front and rear sides of the bottom plate 2 can be adjusted differently according to the structural needs. In addition, by making the plate and the adjacent components or structural surfaces closer to each other, the sealing effect achieved is not limited to preventing water seepage or better assembly. The horizontal keel structure 6 is a generally rectangular columnar U-shaped cavity structure along the left and right extension direction. The opening of the cavity structure faces the direction away from the bottom plate 2, and the side plates 1 arranged on the front and rear sides thereof are flattened on the side away from the bottom plate 2. In addition, the exposed side edges of the transverse keel structure 6 of the present embodiment are all subjected to arc transition treatment, which can effectively improve the safety of assembly construction.

[0033] It should be noted that, in the present embodiment, the side panels 1 and the bottom panel 2 of the transverse keel structure are both made of light steel material, and the transverse keel structure 6 is integrally formed by a stamping process. It can be understood that, in order to adapt to different structural performance requirements, the plate materials in the transverse keel structure of the present invention are not limited to light steel materials, and can be other single materials (such as aluminum alloy, wood, etc.) or a combination of more than one material, and its processing and forming method is not limited to the stamping process, and can include other processes (such as welding, mortise and tenon joints, etc.).

[0034] Figure 2 This is a partial top view of the horizontal keel structure of an assembled wall according to an embodiment of the utility model. Figure 2 As shown, the bottom plate 2 of the transverse keel structure 6 of this embodiment is provided with a partition structure 4 and a positioning hole 5, wherein the partition structure 4 is located on the plate surface protrusion structure of the bottom plate 2, and is a plurality of long strip oblique openings whose extension direction is at a certain angle to the longitudinal direction (left-right direction) of the bottom plate 2, and the plurality of long strip oblique openings are evenly arranged at a certain interval along the longitudinal direction of the bottom plate 2. The partition structure 4 is suitable for utilizing a combination of regularly arranged oblique openings, so that when a fire occurs, the transverse keel structure 6 guides the heat deformation of the keel structure to concentrate at the regularly arranged oblique openings, thereby causing the side plate 1 to deform inward, further clamping the components located between them, ensuring that the entire keel structure does not deform and fall apart rapidly under the influence of high temperature, and always maintaining a certain structural integrity, so as to achieve the effect of fire prevention and delay. In addition, the partition structure 4 can also isolate the sound and heat conduction inside the keel structure, so as to achieve the effect of heat insulation or sound insulation. It can be understood that the opening structure of the partition structure 4 is not limited to oblique strips, and can be other shapes and opening orientations.
