Description

Technical Field

[0001] This utility model belongs to the field of composite slab technology, specifically relating to a composite floor slab connection device. Background Technology

[0002] With the development of the construction industry, prefabricated buildings are increasingly being used in office, residential and other building structures. Large-size prefabricated composite slabs are widely used because of their advantages such as high mass production efficiency, convenient hoisting and installation, and no need for bottom formwork. Composite floor slabs are assembled monolithic floor slabs made by stacking prefabricated slabs and cast-in-place reinforced concrete layers.

[0003] Currently, the connection and assembly of composite slabs relies heavily on complex connection processes such as rebar anchoring and grouting sleeves. On-site work requires extensive rebar alignment, formwork support, and grouting, which is cumbersome and demands extremely high operational precision. Furthermore, due to the complex structure of the connection nodes between different components, construction workers need to repeatedly adjust the alignment, and a single connection often takes several hours, severely restricting the construction progress. In addition, traditional connection methods are highly dependent on the construction environment and the skill level of workers. When encountering adverse conditions such as low temperature and humidity, the grouting strength increases slowly, further extending the assembly cycle and making it difficult to meet the needs of rapid construction in modern industrialized buildings. In such cases, composite slab connection devices are required. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a composite floor slab connection device. This device aims to solve the problem that existing composite slab connection and assembly methods rely heavily on complex rebar anchoring, grouting sleeves, and other connection processes. These require extensive on-site rebar alignment, formwork support, and grouting operations, making the process cumbersome and demanding extremely high precision. Furthermore, the complex structure of the connection nodes between different components necessitates repeated alignment adjustments by construction personnel, often resulting in single connections taking several hours, severely hindering construction progress. In addition, traditional connection methods are highly dependent on the construction environment and worker skill levels. Under adverse conditions such as low temperatures and humidity, the grouting strength increases slowly, further extending the assembly cycle and failing to meet the demands of rapid construction in modern industrialized buildings.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model allows a person to align and insert a hand crank above the transmission rod. Because the transmission rod has limit blocks on top, matching the size and number of limit slots in the middle of the hand crank, the person can rotate the hand crank to rotate the transmission rod under mutual force. This causes the first bevel gear in the middle of the transmission rod to rotate, driving the meshing second bevel gears on both sides. At this time, multiple pairs of second bevel gears can drive their fixed mounting rods and end gears to rotate. In this state, the rack guide blocks on both sides of the gears can also drive their respective... The limiting blocks at different ends extend under the guidance of the sliding groove until the limiting blocks of this part can be aligned and inserted into the corresponding slots in the slots of the composite plate. This achieves the limiting operation of the composite plates on both sides of the connecting frame. Afterwards, the personnel can turn the bolt rod. Under the guidance of the screw groove in the middle of the fixing block, the limiting rod at the end of the bolt rod can be aligned and inserted into the limiting hole opened on the fixing sleeve of the upper section of the transmission rod. This improves the stability of the connection and assembly of the composite plate, and this assembly method facilitates the personnel's subsequent disassembly and assembly.

Then, they can insert two fingers of their thumb and forefinger into the groove above the rubber plug and pull it out. The presence of the rubber plug mainly serves to enhance the aesthetics of the pre-set groove above the connecting frame and to protect its internal components. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a composite floor slab connection device, the structural diagram of which is shown below. Figures 1 to 4 As shown, the device includes a connecting frame 1, with inserts 2 on both sides of the connecting frame 1, and overlapping plates 3 on both sides of the connecting frame 1. Slots 4 are provided on the sides of the overlapping plates 3. An aesthetic protection mechanism 5 is installed above the connecting frame 1. A quick-connect mechanism 6 is installed inside the connecting frame 1 and the multiple pairs of inserts 2. The aesthetic protection mechanism 5 includes a preset groove 51, which is located in the upper middle part of the connecting frame 1. Blocks 52 are fixed on both sides of the upper section of the middle part of the preset groove 51, and rubber plugs 53 are provided above the blocks 52. The rubber plug 53 has a buckle groove 54 on both sides above it. The size of the rubber plug 53 matches the size of the pre-set groove 51. When the construction personnel need to splice the two stacked plates 3, they can first align the corresponding inner end slots 4 of the two stacked plates 3 and insert them into the inserts 2 on both sides of the connecting frame 1. Then, they can insert two fingers of their thumb and forefinger into the buckle groove 54 above the rubber plug 53 and pull it out. The presence of the rubber plug 53 mainly serves to enhance the aesthetics of the pre-set groove 51 above the connecting frame 1 and protect its internal components.

[0027] The quick-connect mechanism 6 includes a connecting component 61, which is installed inside the connecting bracket 1 and multiple pairs of inserts 2. The connecting component 61 includes a transmission rod 611, which is installed in the middle of the connecting bracket 1. Limiting blocks 612 are distributed around the upper section of the transmission rod 611. A hand crank 613 is fitted on the top of the transmission rod 611, and a limiting groove 614 is provided in the middle of the hand crank 613. The size of the limiting groove 614 in the middle of the hand crank 613 matches the size of the limiting blocks 612 distributed around the upper section of the transmission rod 611. First bevel gears 615 are distributed around the periphery of the transmission rod 611, and second bevel gears 616 mesh on both sides of multiple first bevel gears 615. A mounting rod 617 is fixed in the middle of the 6, and gears 618 are fixed around the ends of multiple pairs of mounting rods 617. Rack guide blocks 619 mesh with both sides of the gears 618. Limiting inserts 6110 are fixed at different ends of the rack guide blocks 619. Sliding grooves 6111 are opened on both sides of the ends of multiple pairs of inserts 2. The rack guide blocks 619 and their sliding grooves 6111 are connected in a movable guide manner. The limiting insert 6110 fixed at one end of the rack guide block 619 matches the size of the slot 4 in the slot of the overlapping plate 3. A limiting component 62 is jointly provided around the upper section of the transmission rod 611 and at the upper center of the connecting bracket 1. The limiting component 62 includes a fixing sleeve 621, which is fixed to the upper section of the transmission rod 611. Peripherally, a limiting hole 622 is provided on one side of the middle portion of the fixed sleeve 621. A fixing block 623 is fixed on one side of the upper middle portion of the connecting bracket 1, and a threaded groove 624 is provided in the middle of the fixing block 623. A bolt rod 625 is threaded into the middle of the threaded groove 624, and a limiting rod 626 is fixed at the end of the bolt rod 625. The size of the limiting rod 626 matches the size of the limiting hole 622 provided on one side of the middle portion of the fixed sleeve 621. The operator uses a hand crank 613 to align and insert it above the transmission rod 611. Since the transmission rod 611 has limiting blocks 612 on its upper portion that match the size and number of the limiting grooves 614 provided in the middle portion of the hand crank 613, the operator can rotate the hand crank 613 to drive the transmission rod when the two are under mutual force. When 611 rotates, the first bevel gear 615 in the middle of the transmission rod 611 can rotate, causing the second bevel gears 616 meshing on both sides to rotate. At this time, multiple pairs of second bevel gears 616 can rotate, causing their respective fixed mounting rods 617 and end gears 618 to rotate. In this state, the rack guide blocks 619 on both sides of the gear 618 can extend under the guidance of the sliding groove 6111, with their respective limiting inserts 6110 at different ends, until the limiting inserts 6110 can be aligned and inserted into the corresponding slots in the slots 4 of the composite plate 3. This achieves the limiting operation of the composite plate 3 on both sides of the connecting bracket 1. Afterwards, the operator can tighten the bolt rod 625, guided by the screw groove 624 in the middle of the fixing block 623.The limiting rod 626 at the end of the bolt rod 625 can be inserted into the limiting hole 622 opened on the fixing sleeve 621 on the upper section of the transmission rod 611, thereby improving the stability of the connection and assembly of the composite plate body 3, and this assembly method facilitates subsequent disassembly and assembly by personnel.

[0028] Working principle: When construction workers need to splice two overlapping plates 3, they can first align the corresponding inner end slots 4 of the two overlapping plates 3 and insert them into the inserts 2 on both sides of the connecting frame 1. Then, they can insert two fingers of their thumb and forefinger into the grooves 54 above the rubber plug 53 and pull it out. The rubber plug 53 mainly serves to enhance the aesthetics of the pre-set groove 51 on the top of the connecting frame 1 and protect its internal components. Next, the workers use a hand crank 613 to align and insert it above the transmission rod 611. Since the transmission rod 611 has limit blocks 612 on its top that match the size and number of the limit grooves 614 in the middle of the hand crank 613, the workers can rotate the hand crank 613 to rotate the transmission rod 611 when the two are under mutual force. Thus, the first bevel gear 615 in the middle of the transmission rod 611 can drive the second bevel gears on both sides to mesh. When gear 616 rotates, multiple pairs of second bevel gears 616 can rotate along with their respective fixed mounting rods 617 and end gears 618. In this state, rack guide blocks 619 on both sides of gear 618 can extend under the guidance of sliding groove 6111 with their respective limiting inserts 6110 at different ends until the limiting inserts 6110 can be aligned and inserted into the corresponding slots 4 in the slots of the composite plate 3. This achieves the limiting operation of the composite plate 3 on both sides of the connecting bracket 1. Afterwards, the personnel can tighten bolt rod 625. Under the guidance of the screw groove 624 in the middle of the fixing block 623, the limiting rod 626 at the end of bolt rod 625 can be aligned and inserted into the limiting hole 622 opened on the fixing sleeve 621 on the upper section of the transmission rod 611. This improves the stability of the connection and assembly of the composite plate 3, and this assembly method facilitates the personnel's subsequent disassembly and assembly.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
