Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a construction device and method for installing cast-in-place beams and composite slabs. Background Technology
[0002] In my country, precast concrete structural systems are widely used for residential buildings. Precast housing assembly construction technology embodies the characteristics and advantages of controllable cost, guaranteed quality, economy, and safety, and meets the national requirements for energy conservation, low carbon, and economical development. Currently, it is rapidly developing due to its significant advantages in meeting the requirements of green construction and green building, and is being promoted to public buildings. A certain project is a multi-story frame structure public building that uses a two-way truss composite slab. At present, the mainstream practices for composite slab construction are either to tie the cast-in-place structural beam reinforcement first and then hoist the composite slab, or to hoist the composite slab first and then tie the cast-in-place structural beam reinforcement. The disadvantage of the first method is that the two-way reinforcement on both sides must be bent up and the structural beam reinforcement must be raised to complete the composite slab installation, which leads to reinforcement deformation. The disadvantage of the second method is that the structural beam reinforcement at the two-way reinforcement of the composite slab is not easy to tie, reducing labor efficiency.
[0003] The existing announcement number is CN216787599U, entitled "A Composite Slab Installation Structure," which includes a precast layer, a cast-in-place layer, and a cast-in-place beam. The cast-in-place layer is located on top of the precast layer, and the precast layer is located on both sides of the cast-in-place beam. Multiple longitudinally and transversely intersecting bottom reinforcement bars are provided within the precast layer, extending out of the precast layer and embedded in the cast-in-place beam. The bottom reinforcement bars of the precast layer on both sides of the cast-in-place beam are connected within the cast-in-place beam. Multiple sets of steel trusses are provided within the precast layer, located on the bottom reinforcement bars, with the end of the steel truss away from the bottom reinforcement bars embedded in the cast-in-place layer. Multiple parallel reinforcing bars are provided within the cast-in-place layer, and multiple supports are provided within the cast-in-place beam. The support bars extend into the cast-in-place layers on both sides of the cast-in-place beam. The precast layer is installed in the construction position, and the bottom bars extending from the precast layer are connected and fixed together. The cast-in-place layer and the cast-in-place beam are poured, and the cast-in-place beam fills the bottom bars that are connected together. The bottom bars connect the precast layers on both sides of the cast-in-place beam, which can increase the bonding force between the precast layer and the cast-in-place beam, making the installation between the precast layer and the cast-in-place beam more stable. The cast-in-place layer is connected to the precast layer through the steel truss, making the connection more stable. The support bars in the cast-in-place beam connect the cast-in-place layers on both sides, making the connection between the composite slab and the cast-in-place beam more stable.
[0004] However, when connecting the steel reinforcement components of the cast-in-place beam and the composite slab, the steel reinforcement of the cast-in-place beam is tied first, and then the composite slab is hoisted. The extended steel reinforcement of the composite slab needs to be anchored into the cast-in-place beam. However, after the beam steel reinforcement is tied, the extended steel reinforcement of the composite slab is bent upward. After the composite slab is correctly placed, the cast-in-place beam is lifted with a pry bar, and then the extended steel reinforcement is bent flat again and anchored into the cast-in-place beam. The extended steel reinforcement is bent multiple times in the whole process. It is easy to break during the bending process, which poses a certain risk to construction quality and structural safety. Summary of the Invention
[0005] The purpose of this invention is to provide a construction device and method for installing cast-in-place beams and composite slabs, aiming to improve the above-mentioned problems.
[0006] This invention is implemented as follows:
[0007] A construction device for installing cast-in-place beams and composite slabs includes composite slabs, connectors, seals, frame reinforcement, locking components, and lifting components.

[0013] Furthermore, the locking component includes a first locking housing frame and a second locking housing frame. The first locking housing frame and the second locking housing frame are symmetrically snapped onto the extended reinforcing bars and the frame bars. Screw holes are vertically fixed on adjacent end faces of the first locking housing frame and the second locking housing frame. The adjacent screw holes of the first locking housing frame and the second locking housing frame are assembled and connected by connecting bolts.
[0014] Furthermore, the lifting component includes a center plate, on both sides of the top surface of the center plate are horizontally fixed with sliding columns, and a rotating column is vertically rotatably connected to the center of the bottom surface of the center plate. A locking column is vertically fixed to the bottom end of the rotating column, and a positioning groove is vertically opened at the center of the bottom surface of the locking column.

[0015] Furthermore, offset plates are horizontally arranged on both sides of the center plate, and a hole seat is vertically fixed on the top surface of the offset plate.

A screw hole plate is horizontally fixed on the offset plate, and a support screw is vertically threaded through the screw hole plate. The top end of the support screw is rotatably connected to the bottom surface of the lifting frame.
[0016] A construction method for installing cast-in-place beams and composite slabs includes the following steps:
[0017] S1. First, place the two connecting pieces symmetrically on both sides of the cast-in-place beam, and then hoist the two composite slabs on both sides of the cast-in-place beam respectively.
[0018] S2. At the same time, the extended steel bars at the ends of the two composite plates pass through the assembly sleeve. The rubber sleeve inside the sleeve is tightened inside the sleeve under the elastic compression of the elastic frame. Meanwhile, the threaded sleeve on the extended steel bar is assembled into the screw sleeve on the connector, thereby horizontally guiding and supporting the extended steel bars at the ends of the composite plates to insert into the connector.
[0019] S3. Then, multiple frame bars are vertically set between the two composite slabs, and the two sides of the multiple frame bars are fixed together with the extended steel bars at the ends of the adjacent composite slabs by locking devices.
[0020] S4. Then, according to the assembly gap between the two composite plates on both sides of the cast-in-place beam, slide the two sealing plates. First, pull the insert on the sleeve to slide upward, compress the spring deformation, and slide the two sealing plates horizontally on the hole block through the sliding rod. Release the insert and push the insert into the hole column under the deformation force of the spring. Set the sealing parts on the upper and lower sides of the two connecting parts respectively, and then fix them on the corner plate with fixing bolts.
[0021] S5. Then slide the slider horizontally in the groove of the corner plate. The sealing strip on the slider seals and presses against the gap between the composite slab and the cast-in-place beam. Then, the concrete is guided into the sealing and connecting parts, and the composite slab and the cast-in-place beam are cast into a whole.
[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: First, two connecting pieces are symmetrically arranged on both sides of the cast-in-place beam. Then, two composite slabs are respectively suspended on both sides of the cast-in-place beam. At the same time, the extended reinforcing bars at the ends of the two composite slabs pass through the assembly sleeves. The rubber sleeves inside the sleeves are tightened inside the sleeves under the elastic compression of the elastic frame. Simultaneously, the threaded sleeves on the extended reinforcing bars are assembled into the screw sleeves on the connecting pieces, thereby horizontally guiding and supporting the extended reinforcing bars at the ends of the composite slabs to insert into the interior of the connecting pieces. Then, multiple frame bars are vertically arranged between the two composite slabs. Then, the two sides of the multiple frame bars are fixed together with the extended reinforcing bars at the ends of the adjacent composite slabs by locking pieces. Then, according to the assembly gap between the composite slabs on both sides of the cast-in-place beam, By sliding the two sealing plates, the insert on the sleeve is first pulled upwards, compressing the spring and causing it to deform. The two sealing plates slide horizontally on the hole block via the sliding rod. When the insert is released, the spring's deformation force pushes the insert into the hole bar. The sealing elements are then placed on the upper and lower sides of the two connecting parts and fixed to the corner plate with fixing bolts. Next, the sliding strip slides horizontally in the groove of the corner plate, and the sealing strip on the sliding strip seals and presses against the gap between the composite slab and the cast-in-place beam. Concrete is then guided into the sealing elements and connecting parts. The composite slab and the cast-in-place beam are cast as a whole. Thus, when the concrete is poured and the composite slab is connected, it is assembled first and then poured together as a whole, thereby avoiding the breakage of the extended reinforcing bars on the composite slab and ensuring the construction quality.

First, the insertion post 37 on sleeve 36 is pulled upward to compress the spring 38 and deform. The two sliding sealing plates 31 slide horizontally on hole block 33 through sliding rod 34. When the insertion post 37 is released, under the deformation force of spring 38, the insertion post 37 is pushed into hole column 35, so as to adapt to the size of cast-in-place beam and facilitate the later casting to form an integral beam.

5. A method for installing cast-in-place beams and composite slabs based on the installation construction device for cast-in-place beams and composite slabs as described in claim 4, characterized in that, The steps include the following: S1. First, place the two connecting pieces (2) symmetrically on both sides of the cast-in-place beam, and then hang the two composite slabs (1) on both sides of the cast-in-place beam respectively. S2. At the same time, the extended steel bars (11) at the ends of the two composite plates (1) pass through the assembly sleeve (24). The rubber cylinder (25) inside the sleeve (24) is tightened inside the sleeve (24) under the elastic compression of the elastic frame (26). At the same time, the threaded sleeve (24) on the extended steel bar (11) is threaded into the screw cylinder (23) on the connector (2), thereby horizontally guiding and supporting the extended steel bar (11) at the end of the composite plate (1) to insert into the interior of the connector (2). S3. Then, multiple frame bars (4) are vertically set between two composite slabs (1), and the two sides of the multiple frame bars (4) are fixed together with the extended steel bars (11) at the ends of the adjacent composite slabs (1) by locking parts (5). S4. Then, according to the assembly gap between the two composite plates (1) on both sides of the cast-in-place beam, slide the two sealing plates (31), first pull the insert (37) on the sleeve (36) to slide upward, squeeze the spring (38) to deform, and slide the two sealing plates (31) horizontally on the hole block (33) through the slide rod (34). Release the insert (37) and push the insert (37) into the hole column strip (35) under the deformation force of the spring (38). Set the sealing element (3) on the upper and lower sides of the two connecting parts (2) respectively, and then fix it on the corner plate (21) with the fixing bolt (321). S5. Then slide the slide bar (27) horizontally in the groove (211) of the corner plate (21). The sealing strip (271) on the slide bar (27) seals and presses the gap between the composite plate (1) and the cast-in-place beam. Then the concrete is guided into the sealing element (3) and the connecting element (2). The composite plate (1) and the cast-in-place beam are cast together to form an integral whole.
