Description

Technical Field

[0001] The utility model relates to the technical field of partition wall keels, in particular to a double-cavity partition wall keel. Background Art

[0002] The partition keel is a wall structure used to separate the interior space of a room. It is a building material required for building decoration. The partition wall is usually made up of multiple partition wall modules. During construction, it needs to be used with through-ribs and support cards that support the partition keel, and finally fixed with bolts. The side shape of the current partition keel is mostly U-shaped and a single-layer frame. The interior of the partition keel cannot form a certain space. During construction, the U-shaped walls on both sides of the partition keel will be pushed by the partition wall and deformed to a certain extent. The supporting effect of the partition keel is affected, which in turn affects the installation of the partition wall.

[0003] Therefore, those skilled in the art provide a double-cavity partition wall keel to solve the problems raised in the above background technology. Utility Model Content

[0017] See also Figures 1 to 3In an embodiment of the utility model, a double-cavity partition wall keel includes an outer keel main frame 1 and an inner keel main frame 2. The side of the outer keel main frame 1 is U-shaped, and the upper and lower arms of the outer keel main frame 1 face the inner keel main frame 2. The side of the inner keel main frame 2 is an annular structure. The outer keel main frame 1 is installed on the front side of the inner keel main frame 2. A first cavity 5 is formed inside the inner keel main frame 2. An outer mounting hole 4 is opened on the surface of the outer keel main frame 1, and inner mounting holes 3 are opened on the front and rear surfaces of the inner keel main frame 2. The positions of the inner mounting holes 3 and the outer mounting holes 4 correspond to each other, and connecting bolts 8 are installed through the inner mounting holes 3 and the outer mounting holes 4. By setting the connecting bolts 8, the outer keel main frame 1 and the inner keel main frame 2 can be connected, thereby improving the overall strength of the partition wall keel.

[0018] Preferably, two rows of inner mounting holes 3 and two rows of outer mounting holes 4 are provided, and the two rows of inner mounting holes 3 and the two rows of outer mounting holes 4 are symmetrical about the common central axis of the outer keel main frame 1 and the inner keel main frame 2. Connecting bolts 8 can be installed from both sides to connect the outer keel main frame 1 and the inner keel main frame 2 to enhance the strength of the connection between the outer keel main frame 1 and the inner keel main frame 2.

[0019] Preferably, the upper and lower sides of the inner keel main frame 2 are arranged in a gradient direction toward the outer keel main frame 1, and the spacing between the upper and lower arms of the outer keel main frame 1 is wider than the spacing between the upper and lower sides of the inner keel main frame 2. The front ends of the upper and lower arms of the outer keel main frame 1 are provided with hooks 7, and the hooks 7 are snapped onto the left side surface of the inner keel main frame 2. The outer keel main frame 1 can be snapped into the front side surface of the inner keel main frame 2 through the hooks 7 to complete the preliminary connection between the outer keel main frame 1 and the inner keel main frame 2, so as to facilitate the installation of the connecting bolts 8 into the inner mounting holes 3 and the outer mounting holes 4 in turn, thereby improving work efficiency and avoiding the problem of the outer keel main frame 1 being stuck in the front side surface of the inner keel main frame 2. When the frame 1 and the inner keel main frame 2 are connected by the connecting bolts 8, one end of the outer keel main frame 1 and the inner keel main frame 2 has been fixed, and the other end is still in a state of being separated from each other and not tightly connected, which affects the installation and fixation of the connecting bolts 8. A second cavity 6 is formed between the outer keel main frame 1 and the inner keel main frame 2. Two cavities are formed inside the partition wall keel through the first cavity 5 and the second cavity 6. On the one hand, the use of materials is saved, and on the other hand, the weight of the partition wall keel can be reduced for easy transportation. At the same time, the two cavities are separated from each other, and the anti-support effect is better than that of the partition wall keel with no cavity or one cavity.

[0020] Preferably, the middle parts of the front side and the rear side of the inner keel main frame 2 are respectively recessed with a second recessed groove 10 and a first recessed groove 9. By providing the first recessed groove 9 and the second recessed groove 10, the elasticity and toughness of the inner keel main frame 2 itself can be improved, so that when the inner keel main frame 2 is deformed, the first recessed groove 9 and the second recessed groove 10 can form a pulling force and a supporting force on the upper and lower ends of the inner keel main frame 2. Compared with the setting in which the surface of the traditional partition wall keel is a horizontal plane, the deformation resistance of the inner keel main frame 2 itself can be improved.

[0021] The working principle of the utility model is: when installing the double-cavity partition wall keel, it is necessary to first install the outer keel main frame 1 to the front side of the inner keel main frame 2, and push the outer keel main frame 1 toward the inner keel main frame 2 so that the hooks 7 are inserted into the gradient surfaces set at both ends of the inner keel main frame 2, so that the outer keel main frame 1 and the inner keel main frame 2 are preliminarily connected under the action of the hooks 7, and then the connecting bolts 8 are installed to connect and fix the outer keel main frame 1 and the inner keel main frame 2, thereby completing the assembly of a set of double-cavity partition wall keels, and the outer keel main frame 1 and the inner keel main frame 2 are formed with a first cavity 5 and a second cavity 6, and two cavities are formed inside the partition wall keel through the first cavity 5 and the second cavity 6, one On the one hand, it saves on the use of materials, and on the other hand, it can also reduce the weight of the partition wall keel for easy transportation. At the same time, the two cavities are separated from each other, and the anti-support effect is better than that of a single-cavity partition wall keel. The double-cavity partition wall keel is then installed on the ground where the partition wall needs to be installed, and the partition wall is installed on both sides of the partition wall keel. Since the front and rear side surfaces of the inner keel main frame 2 are respectively concave with the first sunken groove 9 and the second sunken groove 10, the elasticity and toughness of the inner keel main frame 2 itself can be improved. When the partition wall keel is deformed by the partition wall, the first sunken groove 9 and the second sunken groove 10 can form pulling force and supporting force on the upper and lower ends of the inner keel main frame 2, thereby improving the deformation resistance of the inner keel main frame 2 itself.

[0022] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
