Description

Technical Field

[0001] This invention relates to the field of prefabricated floor slab technology, specifically to thermally insulated and energy-saving prefabricated floor slabs and their manufacturing methods. Background Technology

[0002] Prefabricated floor slabs, as an important component of industrialized construction, have been widely used in the construction industry. Traditional construction of insulated prefabricated floor slabs typically involves the following process: first, the prefabricated floor slab is hoisted onto a supporting wall, and concrete is poured on top to form a structural layer; subsequently, scaffolding is erected at the bottom of the floor slab to support the lower formwork, and insulation grout is injected through pre-designed grouting ports on the lower formwork using a grouting machine, ultimately filling the space between the floor slab and the lower formwork to form the lower insulation layer. However, this type of insulated prefabricated floor slab has the following shortcomings:

[0003] 1. After the floor slab is hoisted, the lower formwork and scaffolding support system need to be erected again. Workers need to look up to position the formwork and connect the grouting pipes. High-altitude upward operation is difficult and positioning accuracy is hard to guarantee, which significantly prolongs the construction period.

[0004] 2. When the slurry is filled in a closed space, its fluidity is limited, which can easily lead to uneven distribution. At the same time, the limited working space makes it impossible to implement an effective vibration process, which can result in residual air holes or voids inside the insulation layer, reducing the insulation performance and structural durability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a thermally insulated and energy-saving prefabricated floor slab, which solves the problems mentioned in the background section.

When filling the insulation cavity with insulation mortar, the injection pipe 922 can be inserted through the injection hole set. Workers can complete the filling and grouting of the insulation cavity while standing on the floor slab 100. The grouting is more uniform and the operation is simpler.

[0086] In this embodiment, the first locking member 300 includes a pressure rod 310, a first locking screw 320, and an arc plate 340. Two sets of arc plates 340 are provided at both ends of the pressure rod 310. The two sets of arc plates 340 at one end are respectively pressed on the two second rods 230 of a first steel cage 200. A through hole 311 is symmetrically opened in the middle of the pressure rod 310. The first locking screw 320 passes through the inside of the through hole 311. The first locking screw 320 is located inside the arc plate 340. A first through hole 130 is opened on the surface of the floor slab body 100 for the first locking screw 320 to pass through. The first locking screw 320 passes downward through the first through hole 130. The outer wall of the first locking screw 320 is threadedly connected to a first locking nut 330.

The bottom of the first locking screw 320 extends outward from the second through hole 712, and the portion of the first locking screw 320 extending outward from the second through hole 712 is threadedly connected to a second locking nut 740. The support rod 710 passes between adjacent second inclined rods 620 and is placed at the bottom of two sets of fourth rods 630. Threaded sleeves 720 are symmetrically provided at both ends of the bottom surface of the support rod 710.

The lower constraint groove 410 is positioned directly below the upper constraint groove 140. The two ends of the upper constraint groove 140 are respectively connected to the first grouting hole 110 and the second grouting hole 120.

[0093] The interior of the insulation cavity is reserved with a traction component 800. The traction component 800 includes a rope body 810, a first buckle 820 and a second buckle 830.

[0094] In the above scheme: the traction component 800 reserved on the main body of the floor slab 100 can be easily connected to the mobile grouting device on site. Pulling the first buckle 820 can drive the mobile grouting device to move through the rope 810 and the second buckle 830, so that the mobile grouting device can move and evenly fill the insulation grout 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, so that the translation of the mobile grouting device is smoother and will not deviate.

[0095] The assembly method for thermally insulated and energy-saving prefabricated floor slabs is as follows:

[0096] The first steel cage 200 is placed at intervals on the floor slab body 100. The pressure rod 310 is installed on the floor slab body 100 through the first locking screw 320. The first locking nut 330 is tightened. The two ends of the pressure rod 310 press down on the second rod body 230 of the first steel cage 200 on both sides. The arc plate 340 presses down to position the second rod body 230.

[0100] Example 2

[0101] A method for manufacturing thermally insulated and energy-saving prefabricated floor slabs, the method comprising the following steps:

[0102] S1. The floor slab of Example 1 is hoisted and overlapped onto the supporting wall 500;

[0103] S2, Lower insulation layer filling:

[0104] S2.1. Unfasten the first buckle 820 and the second buckle 830 connected to the first steel cage 200, and connect the second buckle 830 to the movable grouting device;

[0105] S2.2 Connect the mobile grouting device to the grouting pipe 922, and then place the mobile grouting device into the insulation cavity through the second grouting hole 120;

[0106] S2.3 Pull the first buckle 820 outward to make the moving grouting device move along the insulation cavity to evenly fill the insulation cavity with insulation mortar;

[0107] S2.4, Pull out the grouting pipe 922 to make the moving grouting device travel in the opposite direction along the insulation cavity to fill and compact the insulation mortar for a second time;

[0108] S2.5 After the filling of one set of grouting holes is completed, the mobile grouting device is transferred to the next set of grouting holes to complete the filling of the lower insulation layer.

[0109] S3. Filling with upper mortar layer:

[0110] Grouting pipe 922 fills mortar above the main floor slab 100 to form an upper mortar layer, which is integrated with the lower insulation layer at the grouting hole group.

[0111] In the above scheme:

[0112] 1. The pre-reserved traction component 800 can be connected to the mobile grouting device. Based on the first grouting hole 110 and the second grouting hole 120 pre-reserved on the floor slab body 100, the mobile grouting device can be placed from the second grouting hole 120 and pulled from the first grouting hole 110. This allows the mobile grouting device to move and fill between the floor slab body 100 and the lower formwork, resulting in more uniform filling and solving the problem that the grouting operation cannot reach the center position.

[0113] 2. Moving the grouting device can complete uniform grouting and also vibrate the grout, improving the uniformity and density of the grout distribution.

[0114] 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 pre-reserved part for the ceiling.

[0115] like Figures 11-13As shown, in this embodiment, the mobile grouting device includes a front end plate 910, a rear end plate 920, a central tube 950, a discharge pipe 970, and a vibrator 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. The outer wall of the front end plate 910 is provided with a connecting ring 911 connected to the second buckle 830 in the middle. The rear end plate 920 is provided with a connecting joint 921 in the middle. The connecting joint 921 communicates with the central tube 950 and is connected to the grouting pipe 922.

[0116] The top of the central tube 950 is provided with an upper protective plate 930 and the bottom is provided with a lower protective plate 940. The two ends of the upper protective plate 930 are flush with the front end plate 910 and the rear end plate 920. The two ends of the lower protective plate 940 are flush with the front end plate 910 and the rear end plate 920. The surface of the upper protective plate 930 is provided with an upper guide block 931 that fits and is embedded in the upper constraint groove 140. The bottom surface of the lower protective plate 940 is provided with a lower guide block 941 that fits and is embedded in the lower constraint groove 410.

[0117] The two ends of the side wall of the central tube 950 are symmetrically connected to the discharge pipe 970, and multiple sets of vibrating rods 990 are symmetrically arranged in the middle of the side wall of the central tube 950; the side sealing plate 960 is symmetrically slidably installed between the upper guard plate 930 and the lower guard plate 940, and the side sealing plate 960 is symmetrically placed on both sides of the central tube 950, and the side sealing plate 960 is slidably fitted onto the outer wall of the discharge pipe 970 and the vibrating rod 990;

[0118] During the discharge phase, the two sets of side sealing plates 960 move outward, the discharge pipe 970 opens to discharge material, and the vibrator 990 retracts into the inside of the side sealing plates 960.

[0119] During vibration, the two sets of side sealing plates 960 move inward so that the discharge pipe 970 is closed and the vibrating rod 990 is exposed, and multiple sets of vibrating rods 990 work to compact the mortar.

[0120] In the above scheme: when the movable grouting device 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, so as to ensure the stability of subsequent movement;

[0121] The central pipe 950 is equipped with discharge pipes 970 and vibrators 990 on both sides. The grout input by the grouting pipe 922 can be discharged to both sides through the joint 921, the central pipe 950 and the discharge pipe 970 to realize multi-point output filling of concrete; the vibrator 990 can compact the concrete.

[0122] The upper guard plate 930, lower guard plate 940, front end plate 910, rear end plate 920 and side sealing plates 960 on both sides can form a complete shell, and the side sealing plates 960 are movable structures.

[0123] During material discharge, the side sealing plate 960 moves outward to form a complete shell, which reduces walking resistance and makes concrete output smoother. After material discharge is completed, when the vibrator 990 needs to vibrate, the side sealing plate 960 moves outward so that the vibrator 990 can be exposed and compacted.

[0124] In this embodiment, the sidewall of the side sealing plate 960 is symmetrically provided with movable blocks 965, which are 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 equipped with double-threaded rods 980 for driving the side sealing plate 960 to move, and the double-threaded rods 980 are threadedly connected to the movable blocks 965. A first notch 961 is opened at the position opposite to the discharge pipe 970 on the side sealing plate 960, and a second notch is opened at the position opposite to the vibrator 990 on the side sealing plate 960. 962; A self-rotating sealing plate 971 is rotatably installed in the middle of the inside of the discharge pipe 970. A rotating shaft 972 is provided at the middle of both ends of the self-rotating sealing plate 971. The rotating shaft 972 rotates and extends outward from 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 opened on the inner side of the first notch 961 to avoid the driven gear 973. A horizontally arranged rack 964 is provided on the inner wall of the third notch 963. The rack 964 is meshed and positioned below the driven gear 973.

[0125] In the above scheme:

[0126] 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. The moving block 965 drives the side sealing plate 960 to move outward, thus forming a complete shell structure. When the side sealing plate 960 moves 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 the horizontal open state and the torsion spring is compressed.

[0127] When the two sets of side sealing plates 960 need to be moved 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 outward relative to the second notch 962, and the discharge pipe 970 extends outward relative to the first notch 961. The rack 964 drives the driven gear 973 to reverse, causing the self-rotating sealing plate 971 to rotate and block the discharge pipe 970 until the vibrating rod 990 is exposed.
