Description
Technical Field
[0001] The utility model relates to the technical field of laminated plates, in particular to a concrete round-hole laminated plate. Background Art
[0002] The concrete round-hole laminated plate is a structural form that combines a precast floor slab and a cast-in-situ floor slab. The bottom uses a precast concrete thin plate as a permanent formwork, and the upper part is poured with a cast-in-situ concrete composite layer. The two parts of concrete are stressed integrally to form an assembled integral composite floor slab.
[0003] Currently, when placing the bundled steel bars on the concrete thin plate, in order to prevent the bundled steel bars from being impacted by the concrete during the concrete pouring process and causing their position to move, templates are usually placed on the concrete thin plate to limit the bundled steel bars, so as to improve the pouring quality of the laminated plate. However, during the mass production of the laminated plate, it is not convenient to prepare so many templates, and the templates need to be repeatedly taken and placed. There is a lack of a structure for fixing the bundled steel bars on the concrete thin plate, which is not conducive to improving the pouring efficiency of the laminated plate.

Specific implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Refer to Figures 1-4 , a concrete layer is provided on the upper side of the precast slab 1, protection mechanisms 3 are provided on the side surfaces of both the precast slab 1 and the concrete layer, a connection mechanism 4 is slidably connected to the upper side of the precast slab 1, and a connecting rod 5 is fixedly connected to the upper side of the connection mechanism 4;
[0024] The connection mechanism 4 further includes a sliding component 41, a limiting component 42 and a fixing component 43. The sliding component 41 is slidably connected to the inner part of the upper side of the precast slab 1, the limiting component 42 is fixedly connected to the upper side of the sliding component 41, and the fixing component 43 is fixedly connected to the upper side of the sliding component 41.
[0025] Refer to Figure 1 and Figure 3 , the protection mechanism 3 includes a base 31, a protective sleeve 32 and a screw 33. The lower side of the precast slab 1 contacts the base 31, the upper side of the base 31 is fixedly connected to the protective sleeve 32, and the protective sleeve 32 is threadedly connected between the precast slab 1 and the screw 33. More specifically, before transportation, the protective sleeve 32 is installed on the side surface of the precast slab 1, and then the screw 33 is rotated until it is threadedly connected to the precast slab 1, which can prevent the phenomenon that the precast slab 1 has corners missing due to collision during transportation.
[0026] Refer to Figure 1 and Figure 3 , the protective sleeve 32 is made of rubber material. More specifically, the rubber material protective sleeve 32 has a buffering effect and reduces a certain impact force generated by collision during transportation.
[0027] Refer to Figure 2 , Figure 3 and Figure 4, the sliding component 41 includes a connecting plate 411, a slider 412, and a screw 413. The connecting plate 411 is slidably connected to the upper side of the precast slab 1. The connecting plate 411 is fixedly connected to the slider 412. The slider 412 is sleeved inside the precast slab 1. The inside of the connecting plate 411 is threadedly connected to the screw 413, and the screw 413 contacts the precast slab 1. More specifically, it should be further noted that a rubber pad is provided at the bottom of the screw 413. When the screw 413 is rotated, when the rubber pad at the bottom of the screw 413 is separated from the precast slab 1, the connecting plate 411 can be moved. The connecting plate 411 drives the connecting rod 5 to adjust its position. When the screw 413 is rotated in the reverse direction and the bottom rubber pad contacts the precast slab 1, the connecting plate 411 is fixed again. The rubber pad plays a role in enhancing the friction force and preventing the buoyancy generated during the pouring of cement from causing the connecting plate 411 to shift.
[0028] Refer to Figure 2 and Figure 4 , the limiting component 42 includes a plug rod 421, a support plate 422, a fixing block 423, and a tension spring 424. The inside of the screw 413 is slidably connected to the plug rod 421. The plug rod 421 is sleeved inside the support plate 422. The support plate 422 is fixedly connected to the connecting plate 411. One side of the plug rod 421 close to the support plate 422 is fixedly connected to the fixing block 423. One side of the fixing block 423 close to the support plate 422 is fixedly connected to the tension spring 424. The other end of the tension spring 424 is fixedly connected to the support plate 422. More specifically, when the screw 413 is rotated to fix the connecting plate 411, the plug rod 421 is inserted into the inside of the screw 413 under the action of the pulling force of the tension spring 424 to limit it, preventing the screw 413 from rotating and causing the connecting plate 411 to displace.
[0029] Refer to Figure 2 and Figure 4 , the fixing component 43 includes a support block 431 and a snap ring 432. The support block 431 is fixedly connected to the connecting plate 411. The upper side of the support block 431 is fixedly connected to the snap ring 432. The two sides of the snap ring 432 are connected by bolts. More specifically, before pouring, the connecting rod 5 is placed inside the snap ring 432, and then the two sides of the snap ring 432 are made to approach each other through bolts to clamp the connecting rod 5. When the staff welds the connecting rod 5, there is no need to hold it by hand, which is relatively convenient.
[0030] Working mode: When it is necessary to fix the connecting rod 5, place the connecting rod 5 inside the snap ring 432, and then rotate the bolt to make the two sides of the snap ring 432 approach to clamp the connecting rod 5. In this way, when the staff welds the connecting rod 5 and the bundled steel bars, there is no need to support them by hand, which is more convenient; during transportation, install the protective sleeve 32 on the side of the precast slab 1, and then rotate the screw rod 33 to prevent the precast slab 1 from chipping due to collision during transportation; when it is necessary to adjust the position of the connecting rod 5, move the insertion rod 421 away from the support plate 422. When the insertion rod 421 disengages from the screw 413, rotate the screw 413. When the rubber pad at the bottom of the screw 413 disengages from the precast slab 1, the connecting plate 411 can be moved horizontally. The connecting plate 411 drives the slider 412 to slide inside the precast slab 1, and at the same time, the connecting plate 411 drives the connecting rod 5 to adjust the position. After the adjustment is completed, reverse-rotate the screw 413 and fix the connecting plate 411 again when the bottom rubber pad contacts the precast slab 1. The rubber pad plays a role in enhancing the friction, solving the problem that the structure for fixing the bundled steel bars on the concrete thin slab is lacking, which is not conducive to improving the pouring efficiency of the composite slab.
[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
