Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a floor slab structure that combines precast and cast-in-place construction. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] In daily work, it has been found that during the installation of composite slabs, the gaps between the slabs need to be filled with cement. However, the cement tends to leak out through these gaps, resulting in poor joint quality. To solve this problem, the existing technology uses wooden boards to block the flow during pouring. However, this is time-consuming, increases the difficulty of operating the equipment, and consequently makes the equipment difficult to use. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a floor slab structure combining precast and cast-in-place construction is provided to solve the problem of using wooden boards to cover the gaps between existing composite slabs when pouring cement, which consumes a lot of time.

[0005] To achieve the above objectives, a precast and cast-in-place combined floor slab structure is provided, comprising:

[0006] Support plate, overlapping the frame beam;

[0007] Multiple unit composite plates are laid on the support plate. The multiple unit composite plates are arranged along the length direction of the support plate. Each unit composite plate has two adjacent ends. The opposite sides of the end face of the adjacent ends extend to form a butt plate. The butt plate of one adjacent end forms a socket groove, and the butt plate of the other adjacent end forms an insertion part. The insertion part is inserted into the socket groove of the adjacent unit composite plate. The butt plate, the end face, and the support plate enclose a casting groove.

[0008] The pusher plate has a sliding groove at the adjacent end of the unit composite plate, which is set along the length of the pouring groove. A slider slides in the sliding groove. One end of the pusher plate is rotatably mounted on the slider. After concrete is poured into the pouring groove, the pusher plate is rotated so that the other end of the pusher plate extends above the adjacent unit composite plate and pushes against the pusher plate along the length of the pouring groove. The pusher plate scrapes away the concrete that exceeds the opening of the pouring groove, so that the upper surface of the concrete in the pouring groove is flush with the opening of the pouring groove.

[0009] Furthermore, a guide hole is provided on the outer side of the other adjacent end, and a pull rod is elastically installed in the guide hole. One end of the pull rod extends to the outer side of the guide hole and is connected to a locking plate. The locking plate is attached to the outer side of an adjacent end of an adjacent unit composite plate. An insertion hole is provided on the outer side of an adjacent end of an adjacent unit composite plate. A locking rod is formed on the inner side of the locking plate, and the locking rod is detachably inserted into the insertion hole.

[0010] Furthermore, a helical spring is movably sleeved on the outside of the pull rod, one end of the helical spring is connected to the locking plate, and the helical spring is connected to the bottom of the guide hole.

[0011] Furthermore, a handle is connected to one side of the push plate.

[0012] Furthermore, a pivot is vertically provided on the slider, and a shaft hole is opened at one end of the push plate, and the pivot is rotatably inserted into the shaft hole.

[0013] Furthermore, one end face of the push plate is arc-shaped, and a stop bar is formed on the outer side of the pivot. The stop bar fits against the end face of one end of the push plate, and a locking protrusion is formed on the end face of one end of the push plate. After the push plate is rotated so that the other end of the push plate extends above the adjacent unit stacked plate, the locking protrusion abuts against the stop bar to restrict the rotation of the push plate.

[0014] Furthermore, the length of the pusher plate is greater than the width of the casting trough.

[0015] The beneficial effects of this invention are as follows: the precast and cast-in-place combined floor slab structure of this invention, by setting multiple unit composite slabs on the support plate, and the adjacent unit composite slabs being interlocked through the socket grooves and insertion parts of the butt joint plate, forms a casting groove. This facilitates the reduction of cement overflow during pouring, making construction convenient and time-saving. After cement is poured into the casting groove, a push plate is used to smooth the cement at the groove opening, enhancing the overall stability of the floor slab. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 5 As shown, the present invention provides a precast and cast-in-place floor slab structure, including: a support plate 1, a unit composite plate 2, and a push plate 3.

[0025] The support plate 1 overlaps the frame beam. The outer edge of the support plate is installed on the frame beam by welding or bolting.

[0026] The support plate has a large span and multiple unit composite plates 2 are installed on the support plate 1. The multiple unit composite plates 2 are laid on the support plate 1. The multiple unit composite plates 2 are arranged along the length direction of the support plate 1.

[0027] Specifically, the unit composite plate 2 has two adjacent ends. A butt plate 21 extends from opposite sides of the end face of each adjacent end. One adjacent end's butt plate 21 has a socket groove. The other adjacent end's butt plate 21 has an insertion portion 22. The insertion portion 22 is inserted into the socket groove of the adjacent unit composite plate 2. The butt plate 21, the end face, and the support plate 1 together form a casting groove.

[0028] The push plate 3 is used to smooth the concrete at the opening of the pouring trough after the concrete has been poured into the trough.

[0029] Specifically, the adjacent ends of the unit composite slab 2 are provided with a sliding groove 20 arranged along the length of the pouring groove. A slider 31 slides in the sliding groove. One end of the push plate 3 is rotatably mounted on the slider 31. After concrete is poured into the pouring groove, the push plate 3 is rotated so that the other end of the push plate 3 extends above the adjacent unit composite slab 2 and pushes against the push plate 3 along the length of the pouring groove. The push plate 3 scrapes away the concrete that exceeds the opening of the pouring groove, so that the upper surface of the concrete in the pouring groove is flush with the opening of the pouring groove.

[0030] A guide hole is provided on the outer side of another adjacent end of the unit composite plate 2. A pull-out rod 4 is elastically installed in the guide hole. One end of the pull-out rod 4 extends to the outer side of the guide hole and is connected to a locking plate 41. The locking plate 41 is fitted to the outer side of an adjacent end of the adjacent unit composite plate 2. An insertion hole is provided on the outer side of an adjacent end of the adjacent unit composite plate 2. A locking rod 42 is formed on the inner side of the locking plate 41. The locking rod 42 is detachably inserted into the insertion hole.

[0031] In this embodiment, a helical spring 43 is movably sleeved on the outside of the pull rod 4. One end of the helical spring 43 is connected to the locking plate 41. The helical spring 43 is connected to the bottom of the guide hole.

[0032] See Figure 4 As shown, a handle is connected to one side of the push plate 3.

[0033] See Figure 4 and Figure 5 As shown, a pivot 32 is vertically mounted on the slider 31. A shaft hole is provided at one end of the push plate 3. The pivot 32 is rotatably inserted into the shaft hole.

[0034] In a preferred embodiment, the end face of one end of the push plate 3 is arc-shaped. A stop bar 321 is formed on the outer side of the pivot 32. The stop bar 321 is attached to the end face of one end of the push plate 3. A locking protrusion 33 is formed on the end face of one end of the push plate 3. After the push plate 3 is rotated so that the other end of the push plate 3 extends above the adjacent unit stacked plate 2, the locking protrusion 33 abuts against the stop bar 321 to restrict the rotation of the push plate 3.

[0035] See Figure 4 As shown, when the retaining protrusion 33 abuts against the stop bar 321 to restrict the rotation of the push plate 3, the push plate is vertically positioned on the end face of the unit composite plate. The length of the push plate 3 is greater than the width of the casting groove. The bottom of the push plate is attached to the opening of the casting groove.

[0036] In this embodiment, the upper surface of the support plate is provided with two unit composite plates. The mating plates are provided on opposite sides of the end faces of the two unit composite plates.

[0037] The butt joint plate of a single-unit composite slab has a socket groove. The socket groove is fixedly connected to the insertion part of the butt joint plate of the adjacent unit composite slab. An insertion part is provided on one side of the adjacent unit composite slab, and the insertion part is inserted into the socket groove. By setting the butt joint plate, it is easier to reduce cement leakage during pouring, thus increasing the ease of use of the equipment.

[0038] The surface of the mating plate of a unit composite plate is provided with insertion holes. The surface of the locking plate on the adjacent unit composite plates is fixedly connected with locking rods. By setting the locking rods, it is easy to connect the unit composite plates with the adjacent unit composite plates, which increases the stability of the equipment, reduces the difficulty of operation, and facilitates use.

[0039] The locking rod is inserted into the socket on the surface of the connector, and a pull-out rod is fixedly connected to the surface of the locking plate. By setting the pull-out rod, the locking plate can be slid during use, which increases the ease of use of the equipment, facilitates operation, and reduces misalignment between the plates.

[0040] A helical spring is fixedly connected to one side of the locking plate. The helical spring is engaged with the locking plate, causing the locking plate to move towards the mating plate. By incorporating the helical spring, during use, the spring generates elastic force to push the locking plate to slide, increasing the ease of use of the equipment and reducing the difficulty of operation.

[0041] Push plates are provided on the upper surface of adjacent unit composite plates. A slider is slidably connected to the adjacent unit composite plate, and a pivot is fixedly connected to the surface of the slider. The surface of the pivot is rotatably connected to the push plate. The push plate facilitates the leveling of the poured cement, increasing the ease of use of the equipment and reducing the difficulty of operation.

[0042] Specifically, a handle is fixedly connected to the surface of the push plate. The cross-section of the handle is U-shaped. By setting the handle, the push plate is moved by the handle during use, which improves the ease of use of the equipment and makes it convenient to scrape off protruding cement.

[0043] A locking protrusion is fixedly connected to one side of the push plate, and a stop bar is fixedly connected to the side of the slider near the locking protrusion. By setting the locking protrusion, the locking protrusion abuts against the stop bar during use, which facilitates the positioning of the push plate and makes it easier for the push plate to level the protruding cement when moving.

[0044] By setting a docking plate, the unit composite plate is combined with the adjacent unit composite plate. At this time, the plug-in part is inserted into the socket groove. Pulling the pull rod releases the pull rod, and the helical spring loses its restraint and generates elastic force to push the locking plate and drive the locking rod into the plug-in part to complete the positioning. At this time, the unit composite plate is combined with the adjacent unit composite plate. The plug-in part and the socket groove connect the unit composite plate and the adjacent unit composite plate. At the same time, the plug-in part and the socket groove surround the connection between the unit composite plate and the adjacent unit composite plate.

[0045] When pouring cement into the casting tank, the cement is difficult to flow out between the unit composite slabs and adjacent unit composite slabs. By setting up a connecting plate, the operator can be assisted in pouring cement, which reduces cement leakage, increases the stability of the equipment, improves the safety of the equipment, and facilitates the connection between the slabs.

[0046] After the cement is poured into the casting trough, the unevenness of the cement after solidification affects the stability of the floor slab. At this time, the push plate is rotated, and the push plate is parallel to the connection between the unit composite slab and the adjacent unit composite slab. At this time, the locking protrusion follows the rotation of the push plate and abuts against the stop bar, and the push plate stops rotating. Then, the handle pulls the push plate to scrape the protruding cement flat. By setting the push plate, it is easy to level the poured cement, which increases the ease of use of the equipment, reduces the difficulty of operation, increases the stability of the equipment, and strengthens the overall stability of the floor slab.

[0047] In some embodiments, the precast and cast-in-place combined floor slab structure of the present invention further includes a cast-in-place layer (not shown in the accompanying drawings). The cast-in-place layer is cast on multiple unit composite slabs and supporting slabs.
