Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] See also Figure 1-5 The present invention provides a technical solution: a concrete precast panel that is easy to assemble, comprising a precast panel body 1, a front end edge of the precast panel body 1 is provided with engaging grooves 2 at equal intervals in the horizontal direction, a rear end edge of the precast panel body 1 is provided with protrusions 7 at equal intervals in the horizontal direction, the protrusions 7 and the precast panel body 1 are integrally cast by concrete, a splicing mechanism is provided at the protrusions 7 and the engaging grooves 2, and the splicing mechanism facilitates the splicing of two precast panel bodies 1 together.
[0023] The splicing mechanism includes a pre-embedded tube body 10, a movable steel bar 4, a fixed steel bar 3, a strip groove 9, a strip docking groove 8, a clamping block 12 and an extended clamping groove 14. The pre-embedded tube body 10 is horizontally embedded on the inner side wall of the position where the fitting groove 2 is located. The movable steel bar 4 slides horizontally and is inserted into the pre-embedded tube body 10. The fixed steel bar 3 is horizontally fixedly connected below the position where the movable steel bar 4 is located. The strip groove 9 is horizontally opened at the lower end surface of the protrusion 7. The strip docking groove 8 is horizontally opened on the upper end surface of the protrusion 7, and the strip groove 9 and the strip docking groove 8 are extended to the end surface of the end of the protrusion 7. At the same time, the extended end is open. The clamping block 12 is arranged in pairs at the outer end of the movable steel bar 4. The connecting end of the clamping block 12 is attached to the movable steel bar 4. At the same time, the edge of the connecting end of the clamping block 12 away from the movable steel bar 4 is movably connected to the movable steel bar 4 through a rebound hinge. The extended clamping groove 14 is opened in pairs on both sides of the inner end of the strip docking groove 8. Figure 3As shown, when two prefabricated panels 1 are butt-jointed, a certain amount of concrete is poured into the fitting groove 2 at the end of the prefabricated panel 1 in advance, and then the protrusion 7 of one of the prefabricated panel 1 is directly embedded in the fitting groove 2 of the prefabricated panel 1 poured with concrete. At this time, the strip groove 9 is aligned with the fixed steel bar 3, so that the fixed steel bar 3 in the fitting groove 2 is embedded in the strip groove 9 at the bottom of the protrusion 7. At the same time, the protrusion 7, the fitting groove 2 and the fixed steel bar 3 are bonded by the concrete poured in advance, and at the same time, the strip butt joint groove 8 is aligned with the movable steel bar 4, and then the movable steel bar 4 is pulled out to slide into the strip docking groove 8. During this process, the clamping blocks 12 on both sides rotate relative to the movable steel bar 4. When the movable steel bar 4 slides to the extension clamping groove 14 with the clamping blocks 12, the clamping blocks 12 rotate and clamp into the extension clamping groove 14 under the action of the rebound hinge. Since the connecting end of the clamping block 12 fits the side wall of the movable steel bar 4 and cannot be reversed, the end of the movable steel bar 4 is clamped in the strip docking groove 8, thereby realizing the fixed splicing of the two prefabricated panels 1.
[0024] A screw hole 13 is provided at the end of the movable steel bar 4 on the inner side of the embedded tube body 10, and a screw tube 5 is vertically fixedly connected to the upper side of the embedded tube body 10 near the outer end, and the upper end of the screw tube 5 is located at the upper end surface of the prefabricated plate body 1. When the movable steel bar 4 slides out of the embedded tube body 10 and docks into the strip docking groove 8, the screw tube 5 and the screw hole 13 at the end of the movable steel bar 4 are aligned up and down. At this time, a bolt is used to fix and rotate it between the screw tube 5 and the screw hole 13 to fix the movable steel bar 4. In this way, the protrusion 7 of the other prefabricated plate body 1 is completely fixedly connected in the engaging groove 2.
[0025] A finger groove 11 is provided on the upper side wall of the movable steel bar 4 near the outer end, and the finger groove 11 is convenient for the user to insert a finger to pull the movable steel bar 4 to slide.
[0026] The upper end of the embedded pipe body 10 is laterally fixedly connected with a conduit 6, and the upper end of the conduit 6 is located at the upper end surface of the prefabricated panel body 1. After the two prefabricated panels 1 are butt-jointed by means of the protrusion 7 and the fitting groove 2, concrete is poured into the embedded pipe body 10 from the conduit 6, and at the same time, a layer of concrete is covered on the upper side of the strip butt-jointed groove 8, so that the two prefabricated panels 1 are fixedly connected.
[0027] The transverse width of the strip groove 9 is equal to the diameter of the fixed steel bar 3 .
[0028] The inner wall of the embedded pipe body 10 is coated with a lubricant to facilitate the sliding of the movable steel bar 4.
[0029] The conduit 6 and the embedded pipe body 10 are manufactured in an integrated manner.
[0030] Working principle: When two prefabricated panels 1 of the present invention are butt-jointed, a certain amount of concrete is poured into the engaging groove 2 at the end of the prefabricated panel 1 in advance, and then the protrusion 7 of one of the prefabricated panel bodies 1 is directly embedded in the engaging groove 2 of the prefabricated panel body 1 poured with concrete. At this time, the strip groove 9 is aligned with the fixed steel bar 3, so that the fixed steel bar 3 in the engaging groove 2 is embedded in the strip groove 9 at the bottom of the protrusion 7. At the same time, the protrusion 7, the engaging groove 2 and the fixed steel bar 3 are bonded by the concrete poured in advance. At the same time, the strip butt joint groove 8 is aligned with the movable steel bar 4, and then the movable steel bar 4 is pulled out to slide into the strip butt joint groove 8. During this process, the blocks 12 on both sides rotate relative to the movable steel bar 4. When the movable steel bar 4 slides to the extended slot with the blocks 12 14, the block 12 rotates and is inserted into the extension slot 14 under the action of the rebound hinge. Since the connecting end of the block 12 is in contact with the side wall of the movable steel bar 4 and cannot be reversed, the end of the movable steel bar 4 is stuck in the strip docking groove 8, and the two prefabricated panel bodies 1 are fixedly spliced. At the same time, the screw tube 5 in the prefabricated panel body 1 is aligned with the screw hole 13 at the end of the movable steel bar 4 up and down. At this time, a bolt is used to fix and rotate between the screw tube 5 and the screw hole 13 to fix the movable steel bar 4. In this way, the protrusion 7 of the other prefabricated panel body 1 is completely fixedly connected in the embedding groove 2, and concrete is poured into the embedded pipe body 10 from the conduit 6, and a layer of concrete is covered on the upper side of the strip docking groove 8, so that the two prefabricated panel bodies 1 are fixedly connected.
