Description

Technical Field

[0001] The present application relates to the field of in-situ casting of buildings, and particularly to a beam-slab in-situ concrete partition system. Background Art

[0002] During the process of pouring concrete in a beam-slab in-situ system, sometimes due to design or construction requirements, segmented pouring is needed, and sometimes different grades of concrete need to be poured separately. In similar construction situations above, before pouring concrete into the formwork system, construction workers need to set up a structure to intercept the concrete to intercept and partition the concrete in the formwork.

[0003] Refer to Figure 1 , in the related art, a beam-slab in-situ framework includes a beam formwork 01 and a slab formwork 03; the beam formwork 01 includes a bottom formwork 011 and side formworks 012, and the bottom formwork 011 and the side formworks 012 enclose a pouring space, and a beam steel bar framework 02 is arranged in the pouring space; slab formworks 03 are arranged on both sides of the beam formwork 01, and a slab steel bar framework 04 is arranged on the slab formwork 03. The slab steel bar framework 04 includes a number of slab bars 041 that crisscross each other.

[0004] In the related art, when it is necessary to partition the beam-slab formwork system, construction workers will set up wire meshes at the positions where partitioning is required. Since the beam-slab structures are different, the wire meshes for partitioning the beam structure and the wire meshes for partitioning the slab structure need to be installed separately; the wire meshes separate different pouring sections of the beam and the slab, playing a partitioning role to achieve the interception and partitioning of concrete.

[0005] Regarding the above related art, the inventor believes that the airtightness and strength of the wire mesh are limited, and the wire mesh is soft as a whole, and the joints of different wire meshes are easily washed away by concrete, resulting in poor actual concrete partitioning effect. Summary of the Invention

[0006] In order to more effectively partition the concrete in the beam-slab system, the present application provides a beam-slab in-situ concrete partition system.

[0007] A beam-slab in-situ concrete partition system provided by the present application adopts the following technical solutions:

[0008] A beam-slab in-situ concrete partition system includes a beam plugging member. The beam plugging member includes a partition board, and the partition board is a concave-convex board. The partition board is used for the beam steel bar framework to pass through, and the partition board is fixedly connected with the beam steel bar framework; a slab plugging member, the slab plugging member includes at least one blocking board, the blocking board is arranged on the slab formwork, the blocking board is used for intercepting the concrete on the slab formwork, and the partition board abuts against the blocking board.

[0009] By adopting the above technical solution, it is necessary to first build the beam and slab framework before pouring concrete; when binding the beam steel bar framework, the partition board is fixedly installed on the beam steel bar framework, which improves the integration degree between the partition board and the beam steel bar framework, reduces the possibility that the concrete washes away the partition board and the beam steel bar framework, and at the same time, it is also convenient for the construction personnel to carry out unified hoisting in the later stage; after pouring, the partition board is directly left in the beam structure, and only the formwork needs to be removed without taking out the partition board additionally, reducing the workload of the construction personnel.

[0010] When pouring concrete into the beam formwork, the concrete flows in the beam formwork until it contacts the partition board. The presence of the partition board intercepts the flow of the concrete. When the concrete flows to the position of the partition board, due to the structure of the partition board being a concave-convex board, the concrete will flow into the concave space of the partition board. At the same time, the protruding part of the partition board will also be embedded in the concrete. At this time, the concrete can have better bonding with the partition board; when the concrete on both sides of the partition board is poured respectively, the concrete on both sides is interlocked under the influence of the concave-convex structure of the partition board. When the partition surface is subjected to shear force, a resisting force will be generated between the interlocked concrete and the partition board, playing a role in resisting the shear force and reducing the possibility of the formed beam structure breaking; since the shear resistance of the beam needs to be considered during construction, the partition board with the structure of this solution can meet the construction requirements, and compared with the wire mesh with undifferentiated interception, the concrete structure formed after pouring with this solution can better resist the shear force.

[0011] When pouring concrete onto the slab formwork, the blocking board plays a role in blocking the flowing concrete. When building the beam and slab framework, the upper part of the beam steel bar framework needs to extend above the slab formwork. After the blocking board and the partition board are installed, the upper parts of the partition board and the blocking board are both above the slab formwork. At this time, the blocking board and the partition board are abutted, and the gap at the joint between the two is reduced through the abutment, making it difficult for the concrete slurry to flow through the joint between the blocking board and the partition board; if a wire mesh or a quick-setting closing net is used as the beam and slab partition device, due to the soft texture of the wire mesh and the easy bending of the quick-setting closing net, when the two are used as partition devices, the joint of the beam and slab partition device is easily washed open by the concrete, causing waste of concrete; this solution adopts a plate structure, and the joints of the beam blocking member and the slab blocking member are abutted against each other, which can better intercept the concrete; and the blocking board can be disassembled and recovered after pouring on one side, which is beneficial to the secondary utilization of the blocking board and reduces the cost of construction operations.

[0012] When pouring concrete, the newly poured concrete will generate a horizontal pressure, that is, lateral pressure, on the blocking object due to its own weight. Excessive lateral pressure is the reason why mesh structures such as wire meshes and quick-setting closing nets are prone to cracking when used as partition devices; while the partition board and the blocking board with a plate structure are more solid. Using the partition board and the blocking board as partition devices reduces the possibility that the concrete cracks the partition device and also reduces the waste during concrete pouring.

[0013] Combining the above factors and adopting this solution can more effectively partition and intercept the concrete during the pouring process while meeting the requirements of building construction.

[0014] Optionally, a plurality of avoidance grooves are formed in at least one of the blocking plates, and the avoidance grooves are used to avoid the plate reinforcement.

[0015] By adopting the above technical solution, since the plate reinforcement skeleton is provided on the formwork, when building the blocking plate, it is necessary to open avoidance grooves for avoiding the plate reinforcement to ensure that the blocking plate can be smoothly placed on the formwork; the existence of the avoidance grooves facilitates the on-site installation of the blocking plate by construction workers.

[0016] Optionally, the beam sealing member further includes at least one shear-resistant steel bar, the shear-resistant steel bar passes through the partition plate, and the shear-resistant steel bar is fixedly connected to the partition plate.

[0017] By adopting the above technical solution, after the pouring is completed, the partition plate is located in the cast reinforced concrete structure. At this time, under the action of external forces, there is a possibility of cracking at the position where the partition plate is located. Therefore, shear-resistant steel bars are provided to pass through the partition plate, and both ends of the shear-resistant steel bar extend into the concrete structures on both sides of the partition plate respectively. When the partition plate is subjected to shear force, the shear-resistant steel bar can cooperate with the concavo-convex interlocked concrete interface to better resist the shear force and reduce the possibility of cracking at the partition position; at the same time, steel bars are selected for shear resistance because steel bars are everywhere in building construction and are easy to obtain. Construction workers can directly use waste steel bars, improving the waste utilization rate of the construction site.

[0018] Optionally, a first steel wire mesh is provided between the partition plate and the bottom formwork, and the position of the first steel wire mesh is fixed.

[0019] By adopting the above technical solution, in the beam-slab structure, in addition to shear stress, the external force received by the beam also includes tensile stress; when using a partition plate to partition the cast-in-place system of the beam, a concrete fault is formed at the partition position, and the concrete at the fault is likely to crack under the action of tensile stress, resulting in damage to the beam structure; once cracked, it will gradually extend upward from the bottom of the beam structure until the entire beam structure is torn; therefore, a first steel wire mesh is provided between the partition plate and the bottom formwork. When pouring, the concrete on both sides of the partition plate can be combined with the first steel wire mesh. After the concrete solidifies, the first steel wire mesh tightens the concrete structures on both sides of the partition plate to resist the tensile stress received at the bottom of the beam and reduce the possibility of cracking at the partition position, making the formed beam structure more solid; the position of the first steel wire mesh is fixed, reducing the possibility of the first steel wire mesh being washed away by the concrete during pouring.

[0020] Optionally, it further includes a blocking block, the blocking block is clamped between the beam reinforcement skeleton and the bottom formwork, and the first steel wire mesh is fixedly connected to the blocking block.

[0021] By adopting the above technical solution, during actual construction, in order to prevent the steel bar framework from being exposed outside the cast structure, when installing the steel bar framework, a gap with a certain distance is reserved between the steel bar framework and the formwork, so as to form a concrete protective layer after pouring; the gap between the beam steel bar framework and the bottom formwork increases the possibility of concrete flowing from one side of the partition to the other side; therefore, it is necessary to place a blocking block between the bottom formwork and the beam steel bar framework to block the gap between the beam steel bar framework and the bottom formwork, reducing the possibility of concrete passing through the lower gap during pouring and making the partition system better intercept the concrete.

[0022] Optionally, at least one side of the two sides of the partition close to the side formwork is fixedly connected with a second wire mesh, and the second wire mesh extends towards the side close to the bottom formwork.

[0023] By adopting the above technical solution, the beam structure may crack under tensile stress. The cracking generally extends upward from the bottom of the beam. A second wire mesh is arranged at the position of the partition close to the side formwork, and the second wire mesh extends towards the direction close to the bottom of the beam. The second wire mesh combines with the concrete on both sides of the partition during pouring, thereby tightening the structures on both sides of the partition, playing a role in resisting tensile stress, reducing the possibility of the beam structure cracking under stress, and making the formed beam structure more solid.

[0024] Optionally, the beam blocking member further includes a blocking plate, the blocking plate is arranged on the side of the partition away from the bottom formwork, and the blocking plate abuts against the blocking plate.

[0025] By adopting the above technical solution, during actual construction, the height of the partition may not be suitable for the specific conditions of all projects. Sometimes, due to production requirements, it is necessary to extend the partition upward by a certain distance to ensure that the concrete will not pass over the partition; therefore, in some projects, it is necessary for the blocking plate to block the concrete above the partition, making the beam blocking member better intercept the concrete; at the same time, in order to reduce the possibility of concrete leaking from the joint between the blocking plate and the blocking plate, the blocking plate is abutted against the blocking plate, enabling the beam blocking member and the plate blocking member to effectively cooperate to jointly intercept and partition the concrete.

[0026] Optionally, the plate blocking member further includes a plurality of movable members, the movable members are slidably connected to the blocking plate, and the movable members are used to block the avoidance groove.

[0027] By adopting the above technical solution, an avoidance groove for avoiding the plate reinforcement is pre-opened on the blocking plate. Although the avoidance groove is small, there is a possibility of allowing concrete to pass through. Therefore, movable members are provided to block the avoidance groove, reducing the possibility of concrete passing through the blocking plate from the avoidance groove and making the partition effect of the plate blocking member better; when installing and disassembling the blocking plate, the movable members are slid to one side of the avoidance groove, and then the blocking plate can be disassembled and assembled.

[0028] When the movable part intercepts the concrete, the concrete will first enter the space of the avoidance groove and then be blocked by the movable part on one side of the avoidance groove. After the concrete blocked by the movable part and the concrete directly blocked by the blocking plate solidify, the end faces are not on the same plane, forming an uneven stepped surface. During construction, first pour the concrete towards one side of the plate blocking member. After solidification, remove the plate blocking member. The solidified concrete partition surface will form an uneven surface. Then pour the concrete towards the un-poured side. Since the solidified concrete partition surface is uneven, the newly poured concrete will also have an uneven partition surface after solidification. At this time, the concrete on both sides is interlocked at the intersection, facilitating the combination of the two pours of concrete. When the partition of the plate is subjected to shear force, the interlocked partition surfaces can abut against each other to generate a force to resist the shear force, reducing the possibility of fracture at the partition position of the plate.

[0029] Optionally, at least one protrusion is provided on the blocking plate.

[0030] By adopting the above technical solution, a protrusion is provided on the blocking plate. When pouring the concrete, first pour the concrete towards the side of the blocking plate where the protrusion is provided. At this time, the protrusion is embedded in the concrete, and a groove is formed on the solidified concrete partition surface. Then remove the blocking plate by disassembling it. Then pour the new concrete towards the side where the concrete has not been poured. At this time, the newly poured concrete flows into the groove formed by the original concrete, which is beneficial to the combination of the concrete on both sides.

[0031] Optionally, it further includes at least one support member, one end of the support member abuts against the blocking plate, and the other end abuts against the plate steel bar skeleton or the plate formwork.

[0032] By adopting the above technical solution, when pouring the concrete towards one side of the plate blocking member, it is necessary to fix the position of the plate blocking member to ensure that the plate blocking member will not be washed away by the poured concrete. Therefore, construction workers usually fix the blocking plate on the plate steel bar skeleton or the plate formwork. However, since the blocking plate needs to be disassembled, it is very inconvenient to disassemble it later if it is directly fixed on the plate steel bar skeleton or the plate formwork. Therefore, a support member is provided. When pouring the concrete, the support member supports the side of the blocking plate where the concrete has not been poured, reducing the possibility of the blocking plate being pushed away by the concrete. At the same time, when it is necessary to disassemble the blocking plate, only the support member and the blocking plate need to be taken away together, which is convenient for construction workers to disassemble and assemble the blocking plate.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The partition plate and the blocking plate abut against each other, reducing the possibility of concrete passing through between the two. At the same time, the concave-convex plate-shaped partition plate can better grip the concrete. The mutual cooperation of the plate blocking member and the beam blocking member can more effectively block the concrete in the beam-slab system.

[0035] 2. The shear-resistant steel bars play a role in resisting shear force and reduce the possibility of fracture at the partition position of the beam.

[0036] 3. The presence of the first wire mesh and the second wire mesh reduces the possibility of cracking in the formed beam structure.

[0037] 4. The movable part reduces the possibility of concrete passing through the avoidance groove.

[0038] 5. The support member reduces the possibility of the blocking plate being pushed away by the concrete and facilitates the disassembly and assembly of the blocking plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The embodiment of the present application discloses a cast-in-place concrete partition system for beams and slabs.

[0060] Embodiment 1

[0061] Refer to Figure 2 , a cast-in-place concrete partition system for beams and slabs includes a beam plugging member 1 and a slab plugging member 2.

[0062] Refer to Figure 2 , the beam plugging member 1 includes a partition plate 11 and shear-resistant steel bars 12.

[0063] Refer to Figure 2 And Figure 3 , the partition plate 11 is arranged on the beam steel bar framework 02. In this embodiment, the partition plate 11 is a concave-convex plate with a rectangular shape, and the length direction of the partition plate 11 is arranged vertically. In other embodiments, the partition plate 11 can be arranged obliquely; in this embodiment, the partition plate 11 is a profiled steel sheet. In other embodiments, the partition plate 11 can be a corrugated steel sheet, a corrugated board or other rigid seamless plates; the partition plate 11 is located between two stirrups 022, and several first through holes 111 are opened on the partition plate 11 for the longitudinal bars 021 to pass through; in this embodiment, since the diameters of multiple longitudinal bars 021 are not all the same, the diameters of the first through holes 111 are also different, and the longitudinal bars 021 passing through the partition plate 11 are fixedly connected to the inner wall of the first through holes 111 by spot welding.

[0064] Refer to Figure 3, in this embodiment, there are multiple shear-resistant steel bars 12, and the multiple shear-resistant steel bars 12 are distributed in multiple rows. A number of second through-holes 112 are formed in the partition 11, and one shear-resistant steel bar 12 is inserted into each second through-hole 112. The distribution of the second through-holes 112 is adjusted according to the distribution of the shear-resistant steel bars 12. Both ends of the shear-resistant steel bar 12 extend to one side of the partition 11, and the shear-resistant steel bar 12 is welded to the inner wall of the second through-hole 112. In this embodiment, the shear-resistant steel bar 12 includes an anchoring structure 121, and the anchoring structure 121 is located at both ends of the body of the shear-resistant steel bar 12. The anchoring structure 121 can be realized in the form of an end hook or by mechanical anchoring. In this embodiment, the form of mechanical anchoring is adopted, and the anchoring structure 121 is a square steel plate. One anchoring structure 121 is plug-welded through holes at both ends of the body of each shear-resistant steel bar 12. In other embodiments, the anchoring structure 121 is a 135° hook at the end of the body. In other embodiments, the shear-resistant steel bar 12 can be one. By arranging the anchoring structure 121 at both ends of the body of the shear-resistant steel bar 12, the shear-resistant steel bar 12 and the concrete on both sides can be better wrapped, jointly bear various stresses, and reduce the possibility of the concrete structure cracking and damaging after pouring.

[0065] Refer to Figure 3 and Figure 4 , when the beam steel bar skeleton 02 together with the beam plugging member 1 is hoisted into the beam formwork 01, both sides of the partition 11 close to the side formwork 012 extend into the protection gap 013 on the same side. There is a gap between the edge of the partition 11 close to the side formwork 012 and the side formwork 012 on the same side, reducing the possibility of the edge of the partition 11 being exposed outside the concrete structure after pouring. In this embodiment, second wire meshes 114 are welded to both side edges of the partition 11 close to the side formwork 012. In other embodiments, among the two side edges of the partition 11 close to the side formwork 012, only one side edge is welded with a second wire mesh 114. The second wire mesh 114 is in the shape of a rectangular mesh sheet, and the length direction of the second wire mesh 114 is the same as the length direction of the partition 11. The second wire mesh 114 extends towards the side close to the bottom formwork 011. In other embodiments, the outer shape of the second wire mesh 114 can be an irregular shape. The mesh surface of the second wire mesh 114 is parallel to the plate surface of the side formwork 012. The second wire mesh 114 extends to one side of the partition 11 at both ends in the longitudinal direction of the longitudinal bars 021, and there is a certain gap between the second wire mesh 114 and the side formwork 012 on the same side.

[0066] Refer to Figure 3 and Figure 4, in this embodiment, one end of the partition 11 away from the bottom formwork 011 extends to the side of the beam reinforcement cage 02 away from the bottom formwork 011, and one end of the partition 11 away from the bottom formwork 011 is located on the side of the top reinforcement 042 away from the bottom formwork 011; one end of the partition 11 close to the bottom formwork 011 extends into the protection gap 013 between the beam reinforcement cage 02 and the bottom formwork 011. The first wire mesh 113 is welded to one end of the partition 11 close to the bottom formwork 011. The first wire mesh 113 is in the shape of a mesh sheet. The mesh surface of the first wire mesh 113 is parallel to the plate surface of the bottom formwork 011 and there is a certain distance between them. Both ends of the first wire mesh 113 along the length direction of the longitudinal bars 021 extend to one side of the partition 11; in this embodiment, one end of the second wire mesh 114 close to the bottom formwork 011 is in contact with the first wire mesh 113.

[0067] Refer to Figure 3 and Figure 4 , a rectangular block-shaped support block 1131 is provided on the side of the first wire mesh 113 close to the bottom formwork 011. In this embodiment, the support block 1131 is a mortar block. In other embodiments, the support block 1131 can be a concrete block; the support block 1131 is placed between the first wire mesh 113 and the bottom formwork 011, and the support block 1131 plays a supporting role for the first wire mesh 113, reducing the possibility of the first wire mesh 113 coming into contact with the bottom formwork 011 due to construction factors; in this embodiment, there is one support block 1131, and in other embodiments, there are multiple support blocks 1131.

[0068] Refer to Figure 4 , plate sealing members 2 are provided on both sides of the beam sealing member 1 in the length direction of the beam reinforcement cage 02. The plate sealing member 2 includes a blocking plate 21 and a movable member 22.

[0069] Refer to Figure 4 and Figure 5, in other embodiments, the blocking plate 21 can be a complete long plate. In this embodiment, the blocking plate 21 is a rectangular metal plate and there are multiple ones. The lengths of the multiple blocking plates 21 can be the same or different, and the length of each blocking plate 21 is determined according to specific construction requirements; the blocking plate 21 is arranged on the formwork 03, and the length direction of the blocking plate 21 is parallel to the distribution direction of the side formwork 012. During specific construction, multiple sections of the blocking plate 21 can be lapped together, and adjacent blocking plates 21 are in contact with each other. The blocking plate 21 is detachably connected to the formwork reinforcement cage 04 through binding wires; several avoidance grooves 211 are formed in the blocking plate 21, and the avoidance grooves 211 penetrate through the edge of the blocking plate 21 close to the formwork 03. The multiple avoidance grooves 211 are distributed along the length direction of the blocking plate 21. The avoidance grooves 211 are used to avoid the formwork bars 041 whose length direction is parallel to the longitudinal bars 021; in this embodiment, the edge of the blocking plate 21 adjacent to the partition plate 11 and close to the partition plate 11 is in contact with the edge of the partition plate 11. In other embodiments, the plate surface of the blocking plate 21 adjacent to the partition plate 11 is in contact with the plate surface of the partition plate 11.

[0070] Refer to Figure 5 and Figure 6 , in this embodiment, the part of the blocking plate 21 between two avoidance grooves 211 is called the track part 212. Two tracks 3 are welded on each track part 212, and the distribution direction of the two tracks 3 on each track part 212 is perpendicular to the length direction of the blocking plate 21; the track 3 includes a connecting plate 31 and a baffle plate 32. Both the connecting plate 31 and the baffle plate 32 are rectangular plates, and their length directions are both consistent with the length direction of the blocking plate 21. One end of the connecting plate 31 is welded to the blocking plate 21 and the other end is welded to the baffle plate 32. The plate surface of the baffle plate 32 is parallel to the plate surface of the blocking plate 21. The blocking plate 21, the connecting plate 31 and the baffle plate 32 enclose a limiting space 33; the track 3 forms an angle steel, and the opening directions of the two tracks 3 on the track part 212 are opposite to each other.

[0071] Refer to Figure 5 and Figure 6 , in this embodiment, the movable part 22 is a rectangular plate, and the length direction of the movable part 22 is consistent with the length direction of the track 3. One movable part 22 is arranged on each track part 212. Both sides of the movable part 22 in the length direction are located in the limiting space 33 of one track 3 respectively.

The movable part 22 is used to block the space between the avoidance grooves 211 located between the bottom bars 043 and the top bars 042; when the movable part 22 on the track part 212 slides towards the direction close to the adjacent avoidance groove 211, the baffle plate 32 plays a blocking role on the movable part 22, reducing the possibility of the movable part 22 disengaging from the limiting space 33; in other embodiments, dovetail grooves are formed in the blocking plate 21, dovetail blocks are arranged on the movable part 22, and the movable part 22 slides on the blocking plate 21 through the cooperation of the dovetail grooves and the dovetail blocks.

[0073] Implementation principle of Embodiment 1:

[0074] When building the beam steel bar framework 02, let the longitudinal bars 021 pass through the first through holes 111 preset on the partition plate 11, install the beam blocking member 1 on the beam steel bar framework 02, and fix and connect them by spot welding; the concave-convex partition plate 11 is easy to be wrapped with concrete, and the first wire mesh 113 and the second wire mesh 114 play a role in resisting cracking, and the shear-resistant steel bars 12 are used to resist shear force; after pouring concrete, the beam blocking member 1 does not need to be taken out from the beam formwork 01, reducing the workload of the staff.

[0075] After the frame structure of the beam is built, build the slab formwork 03 and the slab steel bar framework 04; insert the blocking plate 21 onto the built slab steel bar framework 04, and fix and connect the blocking plate 21 to the slab steel bar framework 04 by binding wire. Before pouring, slide the movable member 22 to the state where the avoidance groove 211 is blocked; when pouring, first pour towards the side of the blocking plate 21 where the protrusions 23 are provided. The blocking plate 21 and the movable member 22 play a role in hindering the flow of concrete. After one side is poured, cut the binding wire and remove the slab blocking member 2, and then pour the other side; the slab blocking member 2 can be reused, saving construction costs.

[0076] The beam blocking member 1 separates the pouring of the beam structure, and the slab blocking member 2 separates the pouring of the slab structure; the abutment between the beam blocking member 1 and the slab blocking member 2 reduces the possibility of concrete passing through the joint between the two. Through the cooperation between the beam blocking member 1 and the slab blocking member 2, it is possible to better separate and intercept the concrete in the beam-slab cast-in-place system while meeting the construction requirements.

Two rails 3 are provided on each sliding part 213, and the distribution direction of the two rails 3 is perpendicular to the length direction of the blocking plate 21. In this embodiment, the movable member 22 includes a first movable plate 221 and a second movable plate 222. The distribution direction of the first movable plate 221 and the second movable plate 222 is the same as the distribution direction of the two rails 3 on the same sliding part 213. There is a space between the first movable plate 221 and the second movable plate 222, and the first movable plate 221 and the second movable plate 222 are connected by a connecting member 223.

The plate surface of the limiting plate 71 close to the blocking plate 21 and the plate surface of the baffle 32 close to the blocking plate 21 are in the same plane. When the movable part 22 abuts against the butting plate 7, the limiting plate 71 is used to abut against the first movable plate 221. In other embodiments, there is no limiting plate 71. In other embodiments, a handle is arranged on the movable part 22. In other embodiments, the butting plate 7 and the limiting plate 71 are not arranged. After the movable part 22 blocks the avoidance groove 211, the sliding of the movable part 22 is limited by the abutment between the hanging plate 2232 and the bottom reinforcement 043.

[0088] Refer to Figure 11 , in this embodiment, there are multiple telescopic support members 6, and the support member 6 includes a first support rod 61, a second support rod 62 and a sleeve 63. One end of the sleeve 63 is threadedly connected to the first support rod 61, and the other end is threadedly connected to the second support rod 62. A number of first connection rings 215 are welded on the edge of the blocking plate 21 away from the formwork 03 of the slab. The multiple first connection rings 215 are distributed along the length direction of the blocking plate 21. A second connection ring 611 is welded on the first support rod 61. One first connection ring 215 and one second connection ring 611 are buckled with each other and abut when stressed. In this embodiment, an arc-shaped plate 621 is arranged at the end of the second support rod 62 away from the first support rod 61. The convex surface of the arc-shaped plate 621 is welded to the second support rod 62, and the concave surface of the arc-shaped plate 621 is used to abut against the slab reinforcement 041. In other embodiments, wooden blocks are fixedly connected to the formwork 03 of the slab by steel nails, and the second support rod 62 abuts against the wooden blocks. In other embodiments, there is no sleeve 63, the second support rod 62 is sleeved outside the first support rod 61, and the second support rod 62 is threadedly connected to the first support rod 61.

In other embodiments, when the blocking plate 21 is short, there is one support member 6.

[0089] Reference Figure 11 In this embodiment, the beam-slab cast-in-place concrete partition system also includes a limit member 8, which is arranged on the slab formwork 03; in this embodiment, a plurality of limit members 8 are provided, and the limit members 8 are steel nails, which are nailed to the slab formwork 03, and one end of the limit member 8 extends to above the slab formwork 03, and the end of the limit member 8 located above the slab formwork 03 is used to abut against the blocking plate 21; in other embodiments, the limit member 8 is a screw; in other embodiments, the limit member 8 is a wooden block, and the limit member 8 is fixed to the slab formwork 03 by steel nails.

[0090] Implementation principle of Example 2:

[0091] The shear reinforcement 12 is mechanically anchored by tightening the bolts, which makes it easier for construction workers to install the anchor structure 121; the blocking block 4 serves to hinder the concrete, reducing the possibility of concrete flowing between the partition 11 and the bottom template 011; the first steel mesh 113 is embedded in the blocking block 4, and since the blocking block 4 is clamped between the beam reinforcement skeleton 02 and the bottom template 011, the position of the first steel mesh 113 is fixed; in order to ensure the stability of the position of the first steel mesh 113, the first steel mesh 113 is fixed for a second time by fixing the wire 1132, which reduces the possibility of the first steel mesh 113 and the blocking block 4 being offset due to excessive thrust of the concrete; when the partition 11 is installed, the blocking plate 5 is installed above the partition 11, and the construction workers select the blocking plate 5 of appropriate size according to their needs to partition the space above the partition 11.

[0092] When the movable part 22 slides to the position of blocking the avoidance groove 211, the abutment plate 7 reduces the possibility of the movable part 22 sliding too much and detaching from the track 3. When concrete is poured, the thrust generated by the concrete on the movable part 22 is resisted by the limit plate 71 and the baffle plate 32, thereby reducing the possibility of the movable part 22 being washed away by the concrete, thereby making the partition effect of the movable part 22 better. The two movable parts 22 for blocking the avoidance grooves 211 on both sides are arranged together, and the construction personnel can move the two movable parts 22 at one position, so that the construction personnel can efficiently push the movable parts 22 to achieve blocking.

[0093] When it is necessary to limit the plate sealing member 2, the upper part of the blocking plate 21 is supported by the support member 6, and the lower part of the blocking plate 21 is abutted by the limit member 8. When pouring concrete, the thrust generated by the concrete on the plate sealing member 2 is resisted by the support member 6 and the limit member 8, thereby reducing the possibility of the plate sealing member 2 being washed away by the concrete. At the same time, the length of the support member 6 is adjustable, so that the support member 6 can adapt to more different support distances.

[0094] Example 3

[0095] The difference between this embodiment and embodiment 2 is that the structure of the partition 11 is different, the structure of the blocking plate 5 is different, the connection method between the blocking plate 5 and the partition 11 is different, the fixing method of the first steel mesh 113 is different, and the structure of the movable part 22 is different.

[0096] Reference Figure 12 In this embodiment, the partition 11 is a concave-convex plate with a plurality of protrusions 115 and a plurality of grooves 116 on the plate surface. The basic plate type of the partition 11 is a rectangular steel plate. A plurality of rectangular block-shaped protrusions 115 are integrally connected on both plate surfaces of the partition 11. A groove 116 with a rectangular end is opened at the position where the protrusion 115 is provided on the partition 11.

[0097] Reference Figure 12 and Figure 13 In this embodiment, the blocking plate 5 is a rectangular plate, and one end of the blocking plate 5 close to the partition 11 is in contact with a row of ribs 0211 at the top; a plurality of clamping members 52 are provided on the blocking plate 5, and the clamping members 52 are welded to the edges of the blocking plate 5 close to the partition 11, and the plurality of clamping members 52 are distributed along the length direction of the blocking plate 5, and the plurality of clamping members 52 are distributed at intervals; in this embodiment, the clamping members 52 include an extension plate 521, a connecting plate 522 and two fixing plates 523, and the extension plate 521, the connecting plate 522 and the fixing plate 523 are all rectangular plates; the extension plate 52 One end is welded to the blocking plate 5, and the other end is welded to the connecting plate 522. The plate surface of the extension plate 521 is parallel to the blocking plate 5 and the two have the same thickness. A fixing plate 523 is fixedly connected to each of the two ends of the connecting plate 522. The fixing plate 523 is vertically welded to the connecting plate 522. The two fixing plates 523 are both located on the side of the connecting plate 522 away from the extension plate 521. The plate surfaces of the two fixing plates 523 are parallel. The connecting plate 522 and the two fixing plates 523 form a "U"-shaped structure. The open end of the clamping member 52 is located on the side away from the blocking plate 5.

[0098] Reference Figure 12 and Figure 13, each clamping member 52 passes through the gap between two ribs 0211 in the top row. One end of the partition plate 11 away from the bottom formwork 011 is inserted into the space formed by the connecting plate 522 and the fixing plate 523, and the fixing plate 523 is used to abut against the partition plate 11. In other embodiments, the lengths of the two fixing plates 523 are the same. In this embodiment, the lengths of the two fixing plates 523 are different. The shorter fixing plate 523 is located on the side of the partition plate 11 where the concrete is to be poured, and the longer fixing plate 523 is located on the side of the partition plate 11 where the post-poured concrete is located, which is convenient for pulling out the blocking plate 5 after the concrete is poured on one side. In other embodiments, the clamping member 52 does not include the extension plate 521, and the connecting plate 522 is directly fixedly connected to the blocking plate 5.

[0099] Referring to Figure 12 , in this embodiment, a baffle 9 is provided on the side of the beam reinforcement cage 02 close to the bottom formwork 011. The baffle 9 is in the shape of a rectangular plate, and the length direction of the baffle 9 is the same as the length direction of the blocking plate 5. In this embodiment, the baffle 9 is made of steel plate, and the baffle 9 is welded to the bottom row of ribs 0212. The first wire mesh 113 is welded to the edge of the baffle 9 away from the bottom row of ribs 0212. In other embodiments, after the first wire mesh 113 is welded to the baffle 9, the first wire mesh 113 can be further reinforced and tied to the beam reinforcement cage 02 by binding wires.

[0100] Referring to Figure 12 , in this embodiment, there are two bottom rows of ribs 0212, and they are located on both sides of the lower part of the beam reinforcement cage 02. A sealing plate 91 is fixedly connected to the side wall of the baffle 9 away from the bottom formwork 011. The sealing plate 91 is integrally connected or welded to the baffle 9, and the sealing plate 91 is in the shape of a rectangular plate. The sealing plate 91 extends between the two bottom rows of ribs 0212, and the edge of the sealing plate 91 away from the baffle 9 abuts against the edge of the partition plate 11 close to the baffle 9. In other embodiments, the edge of the sealing plate 91 away from the baffle 9 is welded to the edge of the partition plate 11 close to the baffle 9. In other embodiments, there is a gap between the edge of the sealing plate 91 away from the baffle 9 and the edge of the partition plate 11 close to the baffle 9. In other embodiments, when there are multiple bottom rows of ribs 0212, there are multiple sealing plates 91, and the multiple sealing plates 91 are distributed along the length direction of the baffle 9. The sealing plates 91 are used to be inserted into the gaps between adjacent two bottom rows of ribs 0212.

[0101] Referring to Figure 14, in this embodiment, for the two tracks 3 on each sliding part 213, one is located below the surface reinforcement 042 parallel to the longitudinal reinforcement 021, and the other is located on the side of the plug plate 21 close to the formwork 03. Embedding grooves 224 are formed on the movable parts 22 between the two tracks 3. The depth direction of the embedding grooves 224 is consistent with the sliding direction of the movable parts 22, and the opening direction of the embedding grooves 224 faces the adjacent avoidance grooves 211. The opening directions of the embedding grooves 224 on the two movable parts 22 between the two tracks 3 are set to face away from each other. The embedding grooves 224 are used to avoid the bottom reinforcement 043 parallel to the longitudinal reinforcement 021. In this embodiment, the abutting plate 7 and the limiting plate 71 are not provided. When the movable part 22 seals the avoidance groove 211, the bottom wall of the embedding groove 224 abuts against the bottom reinforcement 043 to limit the sliding of the movable part 22 in this way.

[0102] Implementation principle of Embodiment 3:

[0103] The partition plate 11 is selected as a concave-convex plate provided with bumps 115 and grooves 116, so that the concrete can be better wrapped with the partition plate 11 during pouring; the blocking plate 5 can be connected to the partition plate 11 through the clamping member 52. Due to the existence of the clamping member 52, construction workers do not need to use other additional operations to limit the blocking plate 5, and only need to insert the blocking plate 5 on the partition plate 11. At the same time, the extension plate 521 extends into the gap between the partition plate 11 and the blocking plate 5, reducing the possibility of concrete passing through between the blocking plate 5 and the partition plate 11; after pouring on one side is completed, the blocking plate 5 can be removed from the partition plate 11, which is convenient for the reuse of the blocking plate 5 and reduces the construction cost.

[0104] The baffle 9 and the sealing plate 91 block the gap between the partition plate 11 and the bottom formwork 011 to a certain extent, reducing the possibility of concrete flowing under the partition plate 11. At the same time, the first wire mesh 113 is directly fixed on the baffle 9, reducing the possibility of the first wire mesh 113 being washed away by the concrete; the abutting plate 7 and the limiting plate 71 are not provided, but the inner wall of the embedding groove 224 is used to limit the movable part 22, reducing the weight of the plate plugging member 2.

All the plugging plates 21 close to the partition 11 are in contact with the partition 11; among them, the plugging plates 21 located between the plate bars 041 are in contact with or abutted against the adjacent plate bars 041; the plugging plates 21 are detachably connected to each other. In this embodiment, the plugging plates 21 are connected by steel nails. In other embodiments, they can also be tied by binding wires; in this embodiment, the plugging plates 21 are tied to the plate steel bar framework 04 by binding wires. In other embodiments, the plugging plates 21 are detachably connected to the formwork 03 of the plate by steel nails or bolts.
