Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to a detachable cold-bent steel lightweight mortar combined wall and floor slab. Background Art

[0002] Cold-formed steel lightweight mortar composite wall has a high degree of assembly, a short construction period, and excellent thermal insulation and sound insulation performance, which improves the living environment and enhances disaster prevention capabilities. At present, in the cold-formed steel lightweight mortar composite wall structure system, the connection method between the composite wall and the floor slab mainly adopts the method of reserving bolts in the cast-in-place concrete floor slab, and connecting the floor slab and the composite wall by connecting angle steel. However, this connection method has high requirements on the position accuracy of the embedded bolts, and deviations are prone to occur during the installation of the prefabricated composite wall. In addition, the stiffness of this connection method is close to that of a hinge, which causes the overall load-bearing component to show discontinuity in vertical shear resistance, making it easy to be damaged under external loads such as earthquakes.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Example 1

[0027] See also Figure 1-9 A detachable cold-bent steel lightweight mortar composite wall and floor, comprising a wall panel 1 and a floor panel 2, wherein the floor panel 2 is provided with an installation cavity, the wall panel 1 is tongue-and-groove shaped, and has slots 101 reserved on both sides for connection; rectangular clips 3 corresponding to and mating with the slots 101 are provided on both sides of the installation cavity, a traction drive mechanism 4 is provided at the bottom of the rectangular clip 3, a limiting slot 301 is provided at the top of the rectangular clip 3, and damping stoppers 5 corresponding to and mating with the limiting slots 301 are provided at the top of both sides of the installation cavity, when the traction drive mechanism 4 drives the rectangular clip 3 to dock with the slot 101, the damping stopper 5 is limitedly engaged with the limiting slot 301 at the top of the rectangular clip 3.

[0028] In this embodiment, the traction drive mechanism is used to control the horizontal movement of the rectangular clip to cooperate with the corresponding slots on both sides of the installation cavity of the floor slab, thereby realizing a detachable connection. The damping limiter is correspondingly engaged with the limiting slots on the top of the rectangular clip to realize the horizontal limitation of the rectangular clip and the protection of the traction drive mechanism to prevent damage to the mechanism caused by excessive movement. In addition, since the wall panel and the floor slab are connected in a detachable structure and are equipped with a damping limiter, in the event of an earthquake, this embodiment has a certain energy absorption capacity and is not easily damaged.

[0029] In a specific example, the traction drive mechanism 4 includes a spring drive mechanism 40 and a belt transmission mechanism 41. The upper limit of the belt transmission mechanism 41 is provided with a rectangular buckle 3. The spring drive mechanism 40 is driven and connected to the belt transmission mechanism 41 to drive the rectangular buckle 3 into the slot 101.

[0030] The clockwork spring drive mechanism of this embodiment can store and release a large amount of energy, achieve long-lasting and stable power output through mechanical energy conversion, and can be reset. The clockwork spring drive mechanism cooperates with the belt transmission mechanism to realize the installation and disassembly between the rectangular buckle and the slot, thereby realizing the detachable assembly between the wall panel and the floor slab.

[0031] In a specific example, the belt transmission mechanism 41 includes a belt 410, a limit block 411 and a rotating disk 412. The rotating disk 412 is installed at one end of the belt 410, and the other end is connected to the clockwork spring driving mechanism 40. The limit block 411 is fixedly installed on the belt 410, and a limit groove 302 corresponding to the limit block 411 is provided at the bottom of the rectangular buckle 3.

[0032] The limiting block at the top of the belt in this embodiment cooperates with the limiting groove at the bottom of the rectangular buckle to limit and fix, thereby ensuring that the belt can stably transmit the rectangular buckle and send the rectangular buckle into the corresponding groove of the wall panel to complete the preliminary installation.

[0033] It should be noted that the rotating disk of this embodiment is rotatably installed in the grooves on both sides of the installation cavity; when driven by the clockwork spring drive mechanism, the limit block above the belt is always in a horizontal state, and the limit block on the belt will reach from one end to the other end, thereby ensuring the stability of the transmission.

[0034] In a specific example, the clockwork spring drive mechanism 40 includes a clockwork spring 401, a gear plate 402, a gear plate sleeve 403 and a gear transmission plate 404. The clockwork spring 401 is concentrically assembled with the gear plate 402. The gear plate sleeve 403 is installed on the gear plate 402 as a limiting cover plate for the clockwork spring 401. The gear end of the gear transmission plate 404 is meshed with the gear plate 402. A belt 410 is sleeved on the end of the gear transmission plate 404. The gear plate 402 and the gear transmission plate 404 are both rotatably installed on the inner walls on both sides of the installation cavity through a fixed axis.

[0035] This embodiment stores energy through a clockwork spring, which can drive the gear plate and the mutually meshing gear transmission plate to rotate. When the gear transmission plate rotates, the belt sleeved thereon can drive the rectangular buckle to connect and disengage with the slot, thereby achieving a simple structure and high efficiency.

[0036] It should be noted that the gear plate and the gear transmission plate 4 of this embodiment can rotate freely at the ends of their respective fixed shafts.

[0037] In a specific example, a wheel connecting piece 405 is further included, and the wheel connecting piece 405 is installed between the fixed shafts of the gear plate 402 and the gear transmission plate 404 .

[0038] In this embodiment, the wheel connecting piece can make the gear plate and the gear transmission plate work together more stably on the same plane, and the transmission is stable and efficient.

[0039] In a specific example, it also includes a traction rope 6, one end of which is connected to the clockwork spring 401, and the other end is connected to a telescopic fixed support mechanism 7 through a hole reserved in the floor 2, and the two ends of the telescopic fixed support mechanism 7 are respectively connected to the side wall of the wall panel 1 and the floor 2 to form support and fixation.

[0040] In this embodiment, the spring drive mechanism can be driven by the traction rope in cooperation with the telescopic fixed support mechanism. When the spring drive mechanism drives the belt transmission mechanism to put the rectangular buckle into the slot to complete the fixation, the end of the telescopic fixed support mechanism and the side wall of the wall panel can be detachably fixed and installed, thereby improving the installation stability between the wall panel and the floor panel.

[0041] It should be noted that when an earthquake occurs, the traction rope of this embodiment cooperates with the telescopic fixed support mechanism to shake and undergo slight telescopic changes, and part of the energy can be released through the clockwork spring drive mechanism, thereby improving earthquake resistance.

[0042] In a specific example, the telescopic fixed support mechanism 7 includes a connecting plate 701, a telescopic main rod 702, a telescopic support rod 703, an arc-shaped fixer 704, a fastening clamp arm 705 and a bolt fixing rod 706. The connecting plate 701 is installed between the side wall of the wall panel 1 and the floor slab to form an abutment support. The telescopic main rod 702 is rotatably installed on the connecting plate 701. The telescopic main rod 702 is telescopically sleeved in the telescopic support rod 703. One end of the telescopic support rod 703 is connected to the traction rope 6, and the other end is connected to the fastening clamp arm 705. The fastening clamp arm 705 shown is installed on the side wall of the wall panel 1, and holes are arranged at intervals on the telescopic main rod 702, the telescopic support rod 703 and the arc fixer 704. When the clockwork spring driving mechanism 40 is driven by the traction rope 6 to drive the belt transmission mechanism 41 to put the rectangular buckle 3 into the slot 101 to complete the fixation, the telescopic main rod 702, the telescopic support rod 703 and the arc fixer 704 are fixed by installing bolt fixing rods 706 in corresponding holes to complete the limiting fixation, and the bottom of the arc fixer 704 is installed on the floor slab 2.

[0043] The telescopic fixed support mechanism of this embodiment is retractable and fixable through the telescopic main rod and the telescopic support rod in cooperation with the arc-shaped fixer and the bolt fixing rod. The installation structure is firm and has strong adjustability. It is suitable for installation and fixation between floor panels and wall panels, and cooperates with the traction rope to achieve linkage, thereby improving the installation effect of the overall assembly structure.

[0044] In a specific example, it also includes an L-shaped connector 707 and an expansion bolt 708. Two L-shaped connectors 707 are installed side by side on the connecting plate 701 through the expansion bolt 708. A telescopic main rod 702 is hinged between the two L-shaped connectors 707. The fastening clamp arm 705 is hinged to the telescopic support rod 703.

[0045] In this embodiment, the telescopic main rod and the connecting plate are hingedly installed by means of an L-shaped connecting piece in conjunction with expansion bolts, which is easy to install and disassemble. In addition, since the fastening clamp arm and the telescopic support rod, as well as the connecting plate and the telescopic main rod are hinged, they can be rotated up and down to meet the length adjustment requirements of the traction rope. After adjustment, the arc-shaped fixer can be used in conjunction with the bolt fixing rod to complete the fixed limit. The structure is firm and adaptable.

[0046] In a specific example, an umbrella-shaped buckle 502 is connected inside the damping limiter 5 via a damping spring 501 , and the umbrella-shaped buckle 502 corresponds to and cooperates with the limiting slot 301 at the top of the rectangular buckle 3 .

[0047] It should be noted that the damping limiter of the present embodiment can cooperate with the limiting slot on the top of the rectangular buckle to limit the position through the damping spring and the umbrella-shaped buckle. In addition, the arc direction of the umbrella-shaped buckle is toward the wall panel. Therefore, the damping limiter of the present embodiment can be reset and disengaged from the limiting slot through a traction drive mechanism, thereby realizing the detachability between the wall panel and the floor slab.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
