Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated floor slabs, and in particular to a heat-insulating and energy-saving prefabricated floor slab and a manufacturing method thereof. Background Art

[0002] As an integral component of building industrialization, prefabricated floor slabs have been widely adopted in the construction industry. Traditionally, the construction of insulated prefabricated floor slabs employs the following process: First, the prefabricated floor slabs are hoisted onto supporting walls, and concrete is poured on top to form the structural layer. Subsequently, scaffolding is erected at the bottom of the floor slab to support the lower formwork. A grouting machine is connected to the floor slab to inject insulation slurry through pre-set grouting ports in the lower formwork, ultimately filling the space between the floor slab and the lower formwork to form the lower insulation layer.

[0003] However, this kind of thermal insulation assembled floor has the following shortcomings:

[0004] 1. After the floor slab is hoisted, the lower formwork and scaffolding support system need to be set up again. The operators need to look up to position the formwork and connect it with the grouting pipe. The high-altitude upward operation is difficult and the positioning accuracy is difficult to guarantee, which significantly prolongs the construction period.

[0005] 2. When the slurry is filled in a closed space, its fluidity is limited, and uneven distribution is likely to occur. At the same time, due to the constraints of the working space, it is impossible to implement an effective vibration process, which leads to residual pores or voids inside the insulation layer, reducing the insulation performance and structural durability.

By pulling the first buckle 820, the mobile grouting device 900 can be driven to move through the rope body 810 and the second buckle 830, so that the mobile grouting device 900 can move and evenly fill the insulation slurry into the insulation cavity; the upper constraint groove 140 and the lower constraint groove 410 are set to constrain the movement process of the mobile grouting device 900, so that the translation of the mobile grouting device 900 is smoother and will not deviate.

[0101] Example 2

[0102] A method for manufacturing a heat-insulating and energy-saving assembled floor slab, the method comprising the following steps:

[0103] S1. Hoist the floor slab of Example 1 and connect it to the supporting wall 500;

[0104] S2, filling of lower insulation layer:

[0105] S2.1. Undo the first buckle 820 and the second buckle 830 connected to the first reinforcing cage 200, and connect the second buckle 830 to the mobile grouting device 900;

[0106] S2.2. Connect the mobile grouting device 900 to the grouting pipe 922, and then place the mobile grouting device 900 into the heat preservation chamber through the second grouting hole 120;

[0107] S2.3. Pull out the first buckle 820 to move the mobile grouting device 900 along the insulation cavity to evenly fill the insulation cavity with insulation mortar;

[0108] S2.4. Pull out the grouting pipe 922, causing the mobile grouting device 900 to move in the opposite direction within the insulation cavity to refill and compact the insulation mortar.

[0109] S2.5. After one group of grouting holes is filled, the mobile grouting device 900 is moved to the next group of grouting holes to complete the filling of the lower insulation layer;

[0110] S3, filling the upper mortar layer:

[0111] The grouting pipe 922 fills mortar above the floor slab body 100 to form an upper mortar layer, and the upper mortar layer is connected to the lower insulation layer at the injection hole group.

[0112] In the above scheme:

[0113] 1. Through the reserved traction piece 800, it can be docked with the mobile grouting device 900. Based on the first grouting hole 110 and the second grouting hole 120 reserved on the floor slab body 100, the mobile grouting device 900 can be placed from the second grouting hole 120 and pulled from the first grouting hole 110. This can make the mobile grouting device 900 move and fill between the floor slab body 100 and the lower formwork, making the filling more uniform and solving the problem that the grouting operation cannot be extended to the center position;

[0114] 2. The mobile grouting device 900 can complete uniform grouting and vibrate the slurry to improve the distribution uniformity and density of the slurry.

[0115] 3. After processing is completed, the second locking screw can be unscrewed, the template can be removed, and the lower insulation layer can be placed on the roof. The threaded sleeve can be used as a reserved part for the suspended ceiling.

[0116] like Figure 11-13As shown, in this embodiment, the mobile grouting device 900 includes a front end plate 910, a rear end plate 920, a central tube 950, a discharge pipe 970 and a vibrating rod 990. The front end of the central tube 950 is fixedly connected to the front end plate 910, and the rear end is fixedly connected to the rear end plate 920. A connecting ring 911 connected to the second buckle 830 is provided in the middle of the outer wall of the front end plate 910, and a docking joint 921 is provided in the middle of the rear end plate 920. The docking joint 921 is communicated with the central tube 950, and the docking joint 921 is connected to the grouting pipe 922.

[0117] An upper guard plate 930 is provided on the top of the central tube 950, and a lower guard plate 940 is provided on the bottom. The ends of the upper guard plate 930 are flushly connected to the front plate 910 and the rear plate 920. The ends of the lower guard plate 940 are flushly connected to the front plate 910 and the rear plate 920. The surface of the upper guard plate 930 is provided with an upper guide block 931 that fits and fits in the upper constraint groove 140. The bottom surface of the lower guard plate 940 is provided with a lower guide block 941 that fits and fits in the lower constraint groove 410.

[0118] The two ends of the side wall of the central tube 950 are symmetrically connected to the discharge pipe 970, and a plurality of groups of vibrating rods 990 are symmetrically provided in the middle of the side wall of the central tube 950; side sealing plates 960 are symmetrically slidably installed between the upper guard plate 930 and the lower guard plate 940, and the side sealing plates 960 are symmetrically placed on both sides of the central tube 950. The side sealing plates 960 are slidably fitted on the outer walls of the discharge pipe 970 and the vibrating rods 990;

[0119] In the discharge state, the two sets of side sealing plates 960 move outward, the discharge pipe 970 opens to discharge the material, and the vibrating rod 990 retracts into the inner side sealing plate 960;

[0120] In the vibrating state, the two sets of side sealing plates 960 move inward to close the discharge pipe 970 and expose the vibrating rods 990, and the multiple sets of vibrating rods 990 work to compact the mortar.

[0121] In the above solution, when the mobile grouting device 900 is placed in the filling cavity, the upper guide block 931 can be aligned with the upper constraint groove 140 and the lower guide block 941 can be aligned with the lower constraint groove 410 to ensure the stability of subsequent movement.

[0122] Discharge pipes 970 and vibrating rods 990 are arranged on both sides of the central pipe 950. The slurry input from the grouting pipe 922 can be discharged to both sides through the docking joint 921, the central pipe 950, and the discharge pipes 970, realizing multi-point output and filling of concrete; the vibrating rods 990 can vibrate the concrete;

[0123] The upper guard plate 930, the lower guard plate 940, the front end plate 910, the rear end plate 920 and the side sealing plates 960 on both sides can form a complete shell, and the side sealing plates 960 are movable structures;

[0124] During discharge, the side sealing plate 960 moves outward, thus forming a complete shell, thereby reducing walking resistance and making concrete output smoother; after discharge, when the vibrating rod 990 needs to vibrate, the side sealing plate 960 moves outward, thus exposing the vibrating rod 990 and allowing the vibrating rod 990 to vibrate the concrete.

[0125] In this embodiment, the side wall of the side sealing plate 960 is symmetrically provided with a moving block 965, and the moving block 965 is slidably embedded in the front end plate 910 and the rear end plate 920 respectively. The front end plate 910 and the rear end plate 920 are built with a double-headed threaded rod 980 for driving the side sealing plate 960 to move, and the double-headed threaded rod 980 is threadedly connected to the moving block 965; a first notch 961 is provided at the relative position of the side sealing plate 960 and the discharge pipe 970, and a second notch is provided at the relative position of the side sealing plate 960 and the vibration rod 990 962; a self-rotating sealing plate 971 is rotatably installed in the middle of the inner part of the discharge pipe 970, and a rotating shaft 972 is provided in the middle of both ends of the self-rotating sealing plate 971. The rotating shaft 972 rotates and extends the discharge pipe 970, and a torsion spring is installed at the rotating connection. A driven gear 973 is provided at the outer end of the rotating shaft 972; a third notch 963 is provided on the inner side of the first notch 961 to avoid the driven gear 973, and a horizontally arranged rack 964 is provided on the inner wall of the third notch 963, and the rack 964 is meshed and placed below the driven gear 973.

[0126] In the above scheme:

[0127] When the two sets of side sealing plates 960 need to be moved outward, the double-headed threaded rod 980 rotates, and the double-headed threaded rod 980 drives the moving block 965 to move outward, and the moving block 965 drives the side sealing plates 960 to move outward. In this way, a complete shell structure can be formed. When the side sealing plates 960 move outward, the rack 964 passes under the driven gear 973 and drives the driven gear 973 to rotate, so that the self-rotating sealing plate 971 rotates to a horizontal open state and the torsion spring is compressed;

[0128] When the two sets of side sealing plates 960 need to move inward, the double-headed threaded rod 980 reverses, causing the two sets of moving blocks 965 to move inward, and the two sets of side sealing plates 960 move inward synchronously. The vibrating rod 990 extends relatively outward from the second notch 962, and the discharge pipe 970 extends relatively outward from the first notch 961. The rack 964 drives the driven gear 973 to reverse, causing the rotating sealing plate 971 to rotate and block the discharge pipe 970 until the vibrating rod 990 is exposed.
