Description

Technical Field

[0001] The utility model relates to the technical field of building structural components, in particular to an assembled keel. The utility model also relates to a partition wall structure provided with the assembled keel. Background Art

[0002] The main differences between prefabricated buildings and concrete block masonry lie in the construction method, construction speed, quality control, environmental protection performance and design flexibility. In traditional concrete masonry buildings, concrete blocks are used as walls, and it is inevitable to use cement mortar for masonry and plaster the surface layer for leveling. The hollowing rate is high, the curing time is long, and it depends greatly on construction technology and workers. In addition, the large weight and pure rigidity characteristics of concrete block walls are not conducive to building seismic resistance. Because during an earthquake, the heavy concrete block walls are more likely to become unstable under the influence of seismic inertia, and they do not absorb the deformation of the building structure frame but instead cause secondary extrusion to the frame, increasing the risk of building collapse. And a large amount of construction waste and dust pollution will be generated during the construction of concrete block masonry. At the same time, the development direction of buildings is super high-rise steel frame structures, especially not suitable for using traditional concrete blocks as walls, because their own weight is too large, increasing the overall load of the building, increasing the number of pile driving for building foundation piles, and also increasing the amount of steel used. In addition, its own pure rigidity characteristics also violate the sway characteristics of high-rise buildings.

[0003] For traditional light steel keel gypsum board partitions, first install the keel frame, and then fix the gypsum board to both sides of the keel with screws according to the design. Conventional walls need to install two layers of gypsum board on both sides of the keel, and each layer of gypsum board is fixed with screws at a spacing of 200 mm. According to statistics, taking the wall type of double-sided double-layer gypsum board as an example, 144 screws are required per square meter. Each screw is driven one by one by workers with tools, with low work efficiency and time-consuming and laborious. There is also a construction standard that the nail head of the screw fixing the gypsum board sinks into the board surface by 0.5 - 1 mm. If the nail head is higher than the board surface, it will affect the putty scraping. If the nail head is driven too deep, it is easy to punch through the gypsum board and cause the board to fall off. The index that the nail head sinks into the board surface by 0.5 - 1 mm completely depends on the worker's hand feeling and installation technology, and it is very difficult

[0004] to control the qualification rate of a large number of screw construction operations.

[0005] In order to reduce the construction process, an assembled prefabricated wall module system has been proposed. In the prior art, the wall prefabricated module is composed of a base plate (or reinforcement plate) and fireproof rock wool (or rock wool board). The keels used to connect the base plate and the fireproof rock wool need to be used in pairs, and then the base plate, the keel and the fireproof rock wool layer are fixed with screws.

[0006] Moreover, a bridging plate or a "middle" shaped alloy bar needs to be provided between the two keels to achieve connection and sealing. At the same time, the prefabricated rock wool boards in the prior art are generally made of pure rigid materials and lack appropriate flexibility. When workers install them, they can only drag the rock wool board along a certain path from the end of the ceiling and floor keels and slide it into the upper and lower card slots of the ceiling and floor keels from one side for assembly. The existing keel structure is relatively complicated in the prefabrication and construction processes, and the demand for keels is large, which is not conducive to the cost control of construction materials. Summary of the Invention

[0007] In view of this, the present invention aims to provide an assembled keel, which can reduce the number of keels, improve the installation efficiency, and reduce the input cost of construction materials while meeting the requirements of wall prefabrication installation and stiffness.

[0008] To achieve the above object, the technical solution of the present invention is realized as follows:

[0009] An assembled keel includes a middle part for connecting adjacent rock wool boards;

[0010] An end part, at least one of the end parts is arranged on one side of the middle part, and the end part is used for connecting adjacent base plates;

[0011] The middle part includes an upper partition part, a lower partition part, and a connecting part connected between the two;

[0012] The connecting part and the upper partition part, the lower partition part respectively enclose two first open cavities opening outward.

[0013] The end part and the middle part enclose a second open cavity.

[0014] Further, the connecting part is vertically arranged in the middle of the upper partition part and the lower partition part, and the middle part is in an "I" shape.

[0015] Further, the upper partition part and the lower partition part include a first overlapping part and a second overlapping part connected to each other;

[0018] Further, the end part includes a horizontal section and a vertical section arranged vertically;

[0019] The horizontal section, the vertical section and the first overlapping part form the second open cavity;

[0020] One end of the horizontal section is provided with a bent section that bends towards the second open cavity, and the base plate is arranged between the bent section and the first overlapping part.

[0021] Further, the end part is in a "7" shape, and the end part and the middle part enclose a second open cavity.

[0022] Further, the end part is in a "T" shape, and the end part and the middle part enclose two second open cavities;

[0023] The first open cavity and the second open cavity are arranged in parallel.

[0024] Further, the two end parts are respectively arranged on both sides of the middle part, and the end part and the middle part form three "I" shapes connected in sequence from top to bottom.

[0025] Further, the end part further includes a third overlapping part connected to one end of the vertical section;

[0026] The third overlapping part is arranged above the second overlapping part and is connected to the horizontal section;

[0027] Another base plate is arranged between the third overlapping part and the second overlapping part.

[0028] Further, any one of the first overlapping part, the second overlapping part, the third overlapping part, and the bent section includes a "U" - shaped cavity.

[0029] Compared with the prior art, the present utility model has the following advantages:

[0030] For the assembled keel of the present utility model, by enclosing the upper partition part, the lower partition part and the connecting part of the middle part to form two first open cavities opening outwards, it is convenient for two adjacent rock wool boards to be inserted into the first open cavities to be connected with the keel, avoiding the structure in the prior art that two oppositely arranged keels are required for connection, thereby reducing the number and weight of the keels and reducing the construction cost. Moreover, on the basis of the wall - bearing skeleton, the keel and the prefabricated rock wool of the present utility model present a mortise - and - tenon feature, and the two are firmly connected by mortise - and - tenon hinge.

[0031] In addition, by arranging the second open cavity to fix the base plate on one side or both sides of the rock wool board in the second open cavity, there is no need to use screws or the like for re - fastening, and in practical applications, it can meet the use requirements by strengthening with glue or rubber sealing strips.

[0032] In addition, the middle part is set to be in an "I"-shaped structure to adapt to the commonly used rectangular rock wool board, and the "I"-shaped structure can increase the structural strength of the middle part of the keel, effectively resist external loads such as strong winds and impacts, avoid deformation after a period of use, and improve the overall strength of the building.

[0033] Moreover, by setting the end part to be in a "T"-shaped structure, the end part and the upper or lower partition part form an "I"-shaped structure, so that the keel forms a plurality of longitudinally arranged "I"-shaped structures, further improving the structural strength, stiffness and anti-twisting property of the keel. In addition, two adjacent base plates can be inserted into the two second open cavities, which not only reduces the installation process of screws, but also reduces the setting of bridging plates or "middle"-shaped alloy bars to meet the connection and sealing requirements, achieving a better connection effect.

[0036] The partition wall structure of the present invention can reduce the number and weight of the keels while ensuring the sealed installation requirements of the partition wall structure and reducing the screw installation process, which not only improves the production efficiency but also reduces the cost of construction materials.

[0057] Embodiment 1

[0058] This embodiment relates to an assembled keel 1, which includes an intermediate part 11 and an end part 12. Among them, the intermediate part 11 is used to connect adjacent rock wool boards 2. At least one end part 12 is arranged on one side of the intermediate part 11, and the end part 12 is used to connect adjacent base plates 3. The intermediate part 11 includes an upper partition part 1101, a lower partition part 1102, and a connecting part 1103 connected between the two. The connecting part 1103 and the upper partition part 1101, the lower partition part 1102 respectively enclose two first open cavities 1104 opening outward, and the end part 12 and the intermediate part 11 enclose a second open cavity 1206.

[0059] In the assembled keel 1 of this embodiment, by enclosing the upper partition part 1101, the lower partition part 1102 and the connecting part 1103 of the intermediate part 11 to form two first open cavities 1104 opening outward, it is convenient for two adjacent rock wool boards 2 to be inserted into the first open cavities 1104 to be connected with the keel 1, avoiding the structure in the prior art that two relatively arranged keels 1 (or "middle"-shaped alloy bars) need to be used for connection, thereby reducing the number and weight of the keels 1 and reducing the construction cost.

[0060] In addition, by providing the second open cavity 1206, the base plates 3 on one side or both sides of the rock wool board 2 are fixed in the second open cavity 1206, and there is no need to use screws or the like for re-fastening. In practical applications, it can be strengthened by applying glue or using a rubber sealing strip to meet the usage requirements.

[0061] Based on the above overall introduction, an exemplary structure of the assembled keel 1 in this embodiment is as Figure 1 shown. The keel 1 in this embodiment is integrally formed by bending a steel plate. When the specifications of the partition plate or the base plate 3 are different, when manufacturing the keel 1, only the opening thickness of the first open cavity 1104 and the second open cavity 1206 needs to be changed, and the processing method of the keel 1 increases the applicability of the reinforcement.

[0062] It should be noted that the base board 3 in this embodiment can be made of materials such as gypsum board, cement board, calcium silicate board, and magnesium oxychloride board, and can be flexibly selected according to the specific requirements of the wall. The rock wool board 2 is a fireproof rock wool or other sound-insulating material, and the rock wool board 2 is also in a prefabricated plate shape. In this embodiment, the specifications of 50 mm in thickness, 600 mm in width, and 1200 mm in length are adopted. Specifically, rock wool with different bulk densities is selected according to the fire resistance limit requirements of the wall, such as 60 kg / m³, 100 kg / m³, and 120 kg / m³. In actual construction, a surface layer board 5 is also pasted on the outside of the base board 3 and the keel 1, and the surface layer board 5 is the final decorative surface.

[0063] It should be noted that the filling material of the rock wool board in this embodiment is not limited to rock wool, and glass wool, foamed polyurethane, EPS and other filling materials can also be used.

[0064] The assembled keel 1 of this embodiment is applied to the outer walls and roof parts of high-rise buildings. By arranging two first open cavities 1104 in the middle part 11, it is beneficial to install fireproof rock wool or other sound-insulating materials in the two first open cavities 1104, and can effectively improve the sound insulation amount and fire resistance limit.

[0065] As a preferred embodiment, as Figure 1 shown, the connecting part 1103 is vertically arranged in the middle of the upper separating part 1101 and the lower separating part 1102, and the middle part 11 is in an "I" shape. Among them, the connecting part 1103 is a single-layer board arranged vertically, and the upper separating part 1101 and the lower separating part 1102 are parallel boards arranged horizontally. The first open cavity 1104 is formed into a rectangular structure with one end opening after rotating 90 degrees, and the other two first open cavities 1104 are arranged oppositely so that their openings face outward.

[0066] The middle part 11 is arranged in an "I" shape to adapt to the commonly used rectangular rock wool board 2, and the "I" shape can increase the structural strength of the middle part 11 of the keel 1, effectively resist external loads such as strong winds and impacts, avoid deformation after being used for a period of time, and improve the overall strength of the building.

[0067] Furthermore, as Figure 1 shown, the end part 12 is in a "7" shape, and the end part 12 and the middle part 11 enclose a second open cavity 1206. Since the base board 3 is mostly in a rectangular plate shape, the end part 12 is in a "7" shape to adapt to the structure of the rectangular plate. If the edge of the base board 3 is other shapes such as arc-shaped or triangular, the end part 12 can be made accordingly, and no limitation is made here.

[0068] In this embodiment, the end portion 12 is arranged in a "7" shape, which can limit the displacement of the two base plates 3 in the left and right directions, as well as the displacement of one of the base plates 3 in the height direction of the keel 1. The other base plate 3 is fixed by means of bonding. That is to say, the displacement of the base plate 3 on one side in the inside-out direction is restricted by the end portion 12, which can, to a certain extent, limit the detachment of the base plate 3.

[0069] As Figure 1 shown, the upper partition portion 1101 and the lower partition portion 1102 of this embodiment include a first overlapping portion 11011 and a second overlapping portion 11012 that are connected to each other. The first overlapping portion 11011 and the connecting portion 1103 form a first open cavity 1104. The second overlapping portion 11012 and the connecting portion 1103 form another first open cavity 1104. Both the first overlapping portion 11011 and the second portion are formed by overlapping two sections of steel plates after bending. Such a setting is not only for facilitating integral molding, but also for increasing the strength of the upper partition portion 1101 and the lower partition portion 1102, avoiding the deformation of the keel 1 due to the extrusion or outward pulling of the base plate 3, so as to ensure the structural firmness of the keel 1.

[0070] As a specific implementation manner, as Figure 1 shown, the end portion 12 includes a horizontal section 1201 and a vertical section 1202 that are vertically arranged. The horizontal section 1201, the vertical section 1202, and the first overlapping portion 11011 form a second open cavity 1206. One end of the horizontal section 1201 is provided with a bending section 1203 that bends towards the second open cavity 1206, and the base plate 3 is arranged between the bending section 1203 and the first overlapping portion 11011.

[0071] Still as Figure 1 shown, the bending portion is formed into a hook shape with one end of the end of the horizontal section 1201 bent back. The thicknesses of the bending portion and the first overlapping portion 11011 are adapted to the thickness of the base plate 3. By providing the bending portion on the horizontal section 1201, it not only plays a certain transitional role when the base plate 3 is inserted, avoiding the surface scratch of the base plate 3 caused by rubbing against the straight keel 1, but also plays a positioning role for the insertion of the base plate 3.

[0072] Still as Figure 1 shown, the first overlapping portion 11011, the second overlapping portion 11012, and the bending section 1203 all contain a "U" - shaped cavity 1205. By providing the "U" - shaped cavity 1205, the keel 1 has elasticity, forms an elastic resonance for the sound wave transmission path, increases the sound wave transmission resistance, consumes sound energy and converts it into heat energy, thereby increasing the sound insulation ability.

[0073] Certainly, when the distance requirement between the base plate 3 and the rock wool board 2 is small, the two overlapping steel plates in the first overlapping part 11011, the second overlapping part 11012 or the bending section 1203 can be pressed and fitted together, and can be adjusted adaptively according to specific needs.

[0074] It should be noted that the position of the connecting part 1103 in this embodiment is not limited to the middle position in the length direction of the upper separating part 1101, and can also be offset according to needs. Similarly, the position of the vertical section 1202 can be not longitudinally aligned with the connecting part 1103 and can be offset. The specific situation can be determined according to the weight of the base plate 3 and the strength required by the keel 1, and is not limited here.

[0075] For the assembled keel 1 described in the present utility model, by enclosing the upper separating part 1101, the lower separating part 1102 and the connecting part 1103 of the middle part 11 to form two first open cavities 1104 opening outward, it is convenient for two adjacent rock wool boards 2 to be inserted into the first open cavities 1104 to be connected with the keel 1, avoiding the structure that two oppositely arranged keels 1 or a "middle"-shaped alloy bar need to be used for connection in the prior art, thereby reducing the number and weight of the keels 1 and reducing the construction cost.

[0076] Embodiment 2

[0077] This embodiment relates to an assembled keel 1, as Figures 2 to 3 shown. The difference between this assembled keel 1 and that in Embodiment 1 is that the end part 12 is in a "T" shape, and the end part 12 and the middle part 11 enclose two second open cavities 1206. The first open cavity 1104 and the second open cavity 1206 are arranged in parallel. By arranging the first open cavity 1104 and the second open cavity 1206 in parallel, it is convenient for the base plate 3 and the rock wool board 2 layer to be closely attached.

[0078] As Figure 2 and Figure 3 shown, by arranging the end part 12 in a "T" shape, the end part 12 and the upper separating part 1101 or the lower separating part 1102 form an I shape, so that the keel 1 forms a plurality of longitudinally arranged I-shaped structures, further improving the structural strength, stiffness and anti-twisting property of the keel 1. And two adjacent base plates 3 can be inserted into the two second open cavities 1206, which not only reduces the process of installing screws, but also can meet the connection and sealing requirements without setting a bridging plate or a "middle"-shaped alloy bar, achieving a better connection effect while reducing the process of driving screws. Even when the structural adhesive fails, due to the limitation of the keel 1, the base plate 3 will not separate from the rock wool board 2, avoiding safety accidents caused by the falling off of the base plate 3.

[0079] Furthermore, as Figure 2 andFigure 3 As shown, two end portions 12 are respectively arranged on both sides of the middle portion 11, and the end portions 12 and the middle portion 11 form three "I"-shaped structures connected in sequence from top to bottom. When it is necessary to connect the base plates 3 on both sides of the rock wool board 2 according to the construction requirements, the keel 1 is provided with two end portions 12, and the three sequentially connected "I"-shaped keels 1 are integrally processed, further ensuring the structural strength and stiffness of the keel 1, and further enhancing the shear resistance and bending resistance.

[0080] In addition, as Figure 2 and Figure 3 shown, the end portion 12 further includes a third overlapping portion 1204 connected to one end of the vertical section 1202 described in the first embodiment. The third overlapping portion 1204 is arranged above the second overlapping portion 11012 and is connected to the horizontal section 1201. Another base plate 3 is arranged between the third overlapping portion 1204 and the second overlapping portion 11012.

[0081] As Figure 2 and Figure 3 shown in the keel 1 structure, there are two different bending methods. Figure 2 The vertical section 1202 in Figure 3 is connected to the third overlapping portion 1204 and the second overlapping portion 11012.

[0082] Still as Figure 2 and Figure 3 shown, the third overlapping portion 1204 of this embodiment also includes a "U"-shaped cavity 1205, and its function is the same as that of the first overlapping portion 11011 and the second overlapping portion 11012 in the first embodiment, and will not be elaborated here.

[0083] It should be noted that since the partition wall of this embodiment adopts three sequentially connected "I"-shaped structures, it can be used in the outermost enclosing wall inside the house, that is, the wall between the indoor space and the outdoor space. The assembled keel of this structure can ensure the structural strength required for the exterior wall and ensure the stability of the partition wall.

[0084] Embodiment Three

[0085] This embodiment relates to an assembled keel 1, as Figures 4 to 5As shown, the difference between this assembled keel 1 and those in the first and second embodiments lies in that a protrusion 13 protruding towards the second open cavity 1206 is provided on the first overlapping part 11011 or the second overlapping part 11012. The protrusion 13 is made by bending the horizontal section 1201. The cross-section of the protrusion 13 can be structures such as triangular, trapezoidal, arc-shaped, etc., which are not limited herein. The setting of the protrusion 13 is not only to further limit the displacement of the base plate 3 and prevent the base plate 3 from shaking, but also to increase the structural strength of the horizontal section 1201 to further ensure the firm installation of the base plate 3.

[0086] Correspondingly, as Figure 6 shown, a trapezoidally arranged protrusion 13 can also be provided on the vertical section 1202, and its function is the same as that of the above-mentioned protrusion 13, which will not be elaborated herein.

[0087] Embodiment 4

[0088] This embodiment relates to a partition wall structure. As Figures 7 to 9 shown, the partition wall structure includes the assembled keel 1 as described in any one of the first to third embodiments, and a prefabricated wall module.

[0089] The prefabricated wall module includes a rock wool board 2 inserted into the first open cavity 1104 and a base plate 3 inserted into the second open cavity 1206. In practical applications, in order to further ensure the firmness of the base plate 3, a structural sealant or a rubber sealing strip is added between the base plate 3 and the rock wool board 2.

[0090] Moreover, by setting the first overlapping part 11011 and the second overlapping part 11012, the distance between the base plate 3 and the partition can be accurately limited in the inside-outside direction of the partition wall. Then, when preparing the prefabricated wall module, the thickness of the structural adhesive layer 4 can be determined according to the cumulative height of the first overlapping part 11011 and the second overlapping part 11012. A surface layer board 5 is also provided on the outside of the base plate 3, and the surface layer board 5 is adhesively fixed to the keel 1 or the base plate 3 through the structural adhesive layer 4.

[0091] In addition, the keel 1 and the prefabricated wall module in this embodiment are both prefabricated and formed in the factory first. Among them, the prefabricated wall module is formed by prefabricating and bonding the rock wool board 2 of the fireproof rock wool and the base plate 3 in the factory. After entering the site, the prefabricated wall module and the keel are successively inserted at intervals to form the entire partition wall structure.

[0092] The partition wall structure of this embodiment, due to the adoption of any one of the prefabricated keels in Embodiments 1 to 3, has a structural strength that can be used for exterior walls or for interior walls with high load-bearing requirements. By setting the prefabricated keel 1 as described above, not only can the number of keels 1 used in the partition wall be reduced, but also at the joints of two adjacent base plates 3 due to the shielding of the end part 12, to ensure the sealed installation requirements of the partition wall. Moreover, since the keel 1 and the fireproof rock wool board are prefabricated in advance, on-site only gluing and inserting the base plate 3, as well as each prefabricated component are required, thereby reducing the screw installation process, reducing the garbage and pollution at the construction site, improving production efficiency, and reducing the cost of construction materials.

[0093] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
