Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a modular steel bar skeleton floor structure for buildings. Background Art

[0002] The floor slab is a horizontal load-bearing structural component that separates the upper and lower floors of a building. It has two main functions. One is to bear various vertical loads from the floor, including live loads such as people and furniture, and dead loads such as the weight of the building's own structure, and transfer these loads to vertical load-bearing components such as beams, columns, and walls; the other is to divide the building horizontally, dividing different use spaces, such as rooms in a house, different shops in a commercial building, etc.

[0003] In the current modular floor assembly process, in order to ensure the stability and safety of the overall structure after the floor assembly is completed, the steel bars are generally inserted and connected between the floor slabs, and then concrete is poured at the steel bar connection position to form a stable connection structure. In the specific implementation process, due to the pre-existing staggered steel bar structure between adjacent floor slabs, these staggered steel bars form a relatively closed channel with a specific direction. When new steel bars need to be inserted, due to the structural characteristics of the channel and the obstruction of staggered steel bars, the construction workers can only choose to slowly pass the steel bars from one end of the channel. This operation method is extremely cumbersome. The insertion of each steel bar requires the construction workers to spend a lot of time and energy to adjust the angle and position to ensure that it can pass smoothly along the channel. At the same time, this operation requires high skills and experience of the construction workers. If you are not careful, the steel bars may get stuck and cannot be smoothly placed. This greatly increases the difficulty coefficient of the operation, brings many inconveniences and challenges to the assembly of modular floor slabs, and also affects the construction efficiency and project progress to a certain extent.

[0004] To this end, a modular steel frame floor structure for construction is proposed. Summary of the invention

[0005] The object of the present invention is to provide a modular steel frame floor structure for construction, so as to solve the problem of high difficulty in reinforcing bars in the modular steel frame floor proposed in the above-mentioned background technology.

A telescopic hole is provided downward through the lower sub-plate to penetrate the movable sub-plate and the lower sub-plate, an isolation sleeve is inserted into the telescopic holes of the movable sub-plate and the lower sub-plate, and the tube body of the isolation sleeve is fixed inside the through hole of the movable sub-plate, a pressure relief valve for relieving pressure on the isolation sleeve is installed in the tube of the isolation sleeve at a position corresponding to the sealing groove, a bending piston and a rubber pushing piston are respectively provided in the tube of the isolation sleeve at the upper and lower ends of the pressure relief valve for sealing and sliding, the rod body of the rubber pushing piston slides out of the isolation sleeve and is fixed at the lower end to the pressure plate located at the bottom of the lower sub-plate.

[0007] Preferably, both ends of the upper steel bars and the lower steel bars are exposed outside the main body of the floor slab, and are bent and hooked in a downward or upward manner.

[0008] Preferably, the lower end of the cooperative reinforcement is hemispherical and is located on one side close to the main body of the floor slab, and is arranged adjacent to the telescopic sleeve and the support sleeve. The telescopic sleeve and the support sleeve are arranged close to the adjacent floor slab and are located in the middle of the overlapping part of the lower steel bars of the adjacent floor slab and the lower steel bars of the main body.

[0009] Preferably, the side of the support sleeve facing the cooperative reinforcement is integrally provided with an anti-slip seat for docking with the cooperative reinforcement, and the inner concave surface of the support sleeve is connected to the elastic rib plate in a manner that the two side edges are fixed, and there is a crescent-shaped gap between the support sleeve and the elastic rib plate, and the support sleeve and the elastic rib plate are both made of elastic plates, and the surface of the elastic rib plate is provided with the same anti-slip texture as the surface of the steel bar.

[0010] Preferably, the movable sub-plate is in sliding contact with the side surface of the floor main body, and the interior of the movable sub-plate is provided with an open groove having the same width as the groove opened on the surface of the floor main body.

[0011] Preferably, the bottom of the sealing groove and the lower surface of the insert are provided with a groove body space capable of satisfying the pressure relief of the pressure relief valve, and the groove body is sealed at the position of the pressure relief valve.

[0012] Preferably, the interior of the isolation sleeve stores fluid material for filling the sealing groove between the rib bending piston and the rubber pushing piston.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses the setting of modular floor structure. During the process of lifting, dropping and installation, the gravity of the floor is used to cooperate with the linkage between the rubber pushing piston, the bending piston, the coordinated picking steel bar, the support sleeve and the elastic rib plate to automatically expand the upper entrance of the steel mesh, creating convenient conditions for the placement of steel bars. At the same time, the gravity of the introduced steel bars can be used to reset the bent steel bars to the initial state, further improving the convenience of steel bar placement. Compared with the current operation method, construction workers no longer need to introduce steel bars from one end of the trough with difficulty, but only need to stably lower the steel bars into the expanded entrance, which greatly reduces the difficulty of operation, improves construction efficiency, and effectively solves the problem of high difficulty in threading steel bars in traditional modular floor slabs. Especially when multiple steel bars need to be introduced to meet the requirements of structural connection and reinforcement, this convenience is more significant; 2. The present invention adopts the setting of modular floor structure. After the steel bars are placed and reset, the upper steel bars push the bending piston to compress the fluid material, increase the internal pressure of the isolation sleeve to open the pressure relief valve, and the fluid is discharged into the sealing groove to support the movable sub-plate to move up. Finally, the movable sub-plate is flush with the surface of the floor body, so that the movable sub-plate and the lower sub-plate are spaced apart. This space provides sufficient space for subsequent concrete casting. The concrete can be fully filled into the steel bar connection part and the gap between the movable sub-plate and the lower sub-plate. Compared with the traditional floor structure, the present invention ensures that the concrete casting is more dense and uniform, better wraps the steel bar connection part, and enhances the bonding force between the steel bar and the concrete, thereby greatly improving the stability of the entire floor structure connection.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The present invention provides a technical solution for a modular steel frame floor structure for a building: A modular steel frame floor structure for construction, comprising a modular floor structure 1, a prefabricated modular building floor, with a stable steel frame built in; The modular floor structure 1 includes a floor body 11, wherein the interior of the floor body 11 is sealed with upper steel bars 111, lower steel bars 112 and a steel bar structure cross-bound thereto in a specified manner, wherein both ends of the upper steel bars 111 and the lower steel bars 112 are exposed outside the floor body 11, and are bent and hooked back in a downward or upward manner, and both ends of the upper steel bars 111 exposed outside the floor body 11 are integrally provided with cooperative pick bars 1111 on the side facing the lower steel bars 112, and both ends of the lower steel bars 112 exposed outside the floor body 11 are welded with telescopic sleeves 1121 on the side facing the upper steel bars 111, and the output end of the telescopic sleeve 1121 is fixed with a support by bolts. The sleeve 1122, the lower end of the cooperative reinforcement 1111 is hemispherical and is located on the side close to the floor body 11, and is adjacent to the telescopic sleeve 1121 and the support sleeve 1122. The telescopic sleeve 1121 and the support sleeve 1122 are arranged close to the adjacent floor, and are located in the middle of the overlapping part of the lower reinforcement 112 of the adjacent floor and the lower reinforcement 112 of the main body. The side of the support sleeve 1122 facing the cooperative reinforcement 1111 is integrally provided with an anti-slip seat that is docked with the cooperative reinforcement 1111 and has the same structure as the support sleeve 1122 and the elastic rib plate 1123, and the inner concave surface of the support sleeve 1122 is connected to the elastic rib plate 1123 in a manner that the two sides are fixed, and there is a moon between the support sleeve 1122 and the elastic rib plate 1123. The tooth-shaped gap is formed, and the support sleeve 1122 and the elastic rib plate 1123 are both made of elastic plates, and the surface of the elastic rib plate 1123 is provided with the same anti-slip texture as the surface of the steel bar. The surface of the floor slab body 11 is provided with an open groove at the position of the upper steel bar 111 for facilitating the upper steel bar 111 to bend upward, and the left and right sides of the floor slab body 11 are fixedly provided with a lower sub-plate 113 on the lower side of the groove. The upper surface of the lower sub-plate 113 is provided with a sealing groove 1131 of a specified length along the radial direction of the lower sub-plate 113, and the sealing groove 1131 is cooperated with the insert strip 1141 integrally arranged at the bottom center position of the movable sub-plate 114 to be slidably connected with the movable sub-plate 114, and the movable sub-plate 114 is connected to the floor slab body 11 The movable sub-plate 114 is in sliding contact with the side thereof, and an open groove of the same width is provided inside the movable sub-plate 114 according to the groove provided on the surface of the floor slab body 11, and a telescopic hole 1142 is provided inside the movable sub-plate 114 from the center position of the open groove downward through the lower sub-plate 113 to penetrate the movable sub-plate 114 and the lower sub-plate 113, and an isolation sleeve 1134 is inserted into the telescopic holes 1142 of the movable sub-plate 114 and the lower sub-plate 113, and the tube body of the isolation sleeve 1134 is fixed inside the through hole of the movable sub-plate 114, but is not fixed to the movable sub-plate 114, and a bending piston 1136 and a rubber pushing piston 1133 are respectively provided in the tube of the isolation sleeve 1134 at the upper and lower ends of the pressure relief valve 1135 in a sealed and slidable manner,The interior of the isolation sleeve 1134 stores fluid material for filling the sealing groove 1131 between the bending piston 1136 and the rubber pushing piston 1133. The rod of the rubber pushing piston 1133 slides out of the isolation sleeve 1134 and is fixed at the lower end to the pressure plate 1132 located at the bottom of the lower sub-plate 113. The spacing between the pressure plate 1132 and the lower sub-plate 113 can meet the bending of the upper steel bar 111 in a predetermined angle range.

[0023] When the prefabricated modular floor structure 1 is hoisted and dropped for installation, the floor gravity causes the pressure plate 1132 to drive the rubber push piston 1133 to move upward, pushing the fluid material to act on the bending piston 1136, supporting the upper steel bar 111 to bend it upward, unfolding the steel mesh entrance, and at the same time coordinating the pick 1111 to move into the anti-slip seat of the support sleeve 1122 and push the support sleeve 1122 upward to stretch the telescopic sleeve 1121. The construction worker uses this entrance to pass four or five steel bars, and puts one steel bar on the elastic rib plate 1123, which pushes the support sleeve 1122 and the cooperative pick rib 1111 through the elastic rib plate 1123, so that the upper steel bar 111 is reset, and the elastic rib plate 1123 is concave to hold the positioning steel bar tightly.

[0024] To sum up, through the setting of the modular floor structure 1, during the lifting and falling installation process, the gravity of the floor is utilized, and the linkage between the rubber pushing piston 1133, the bending rib piston 1136, the coordinated picking rib 1111, the support sleeve 1122 and the elastic rib plate 1123 is coordinated to automatically unfold the upper entrance of the steel mesh, creating convenient conditions for the insertion of steel bars. At the same time, the gravity of the introduced steel bars can be used to reset the bent steel bars to their initial state, further improving the convenience of steel bar insertion. Compared with the current operation method, construction workers no longer need to difficultly introduce steel bars from one end of the trough, but only need to stably lower the steel bars into the unfolded entrance, which greatly reduces the difficulty of operation, improves construction efficiency, and effectively solves the problem of high difficulty in threading steel bars in traditional modular floors, especially when multiple steel bars need to be introduced to meet structural connection and reinforcement requirements, this convenience is more significant.

[0025] As an embodiment of the present invention, Figure 4 As shown, a pressure relief valve 1135 for relieving pressure on the isolation sleeve 1134 is installed inside the tube of the isolation sleeve 1134 at a position corresponding to the sealing groove 1131, and a groove body space that can meet the pressure relief needs of the pressure relief valve 1135 is provided at the bottom of the sealing groove 1131 and the lower surface of the insert 1141, and the groove body is sealed at the position of the pressure relief valve 1135.

[0026] During operation, the upper steel bar 111 is reset and the bending piston 1136 is pushed downward, compressing the fluid material to increase the internal pressure of the isolation sleeve 1134, and the pressure relief valve 1135 is opened, and the fluid is leaked into the sealing groove 1131. The pressure pushes the movable sub-plate 114 upward and finally makes it flush with the surface of the floor main body 11, so that the movable sub-plate 114 and the lower sub-plate 113 are spaced apart, providing space for concrete casting.

[0027] In summary, through the setting of the modular floor structure 1, after the steel bars are placed and reset, the upper steel bars 111 push the bending piston 1136 to compress the fluid material, and the internal pressure of the isolation sleeve 1134 increases to open the pressure relief valve 1135. The fluid leaks into the sealing groove 1131 to support the movable sub-plate 114 to move upward, and finally the movable sub-plate 114 is flush with the surface of the floor body 11, so that the movable sub-plate 114 and the lower sub-plate 113 are spaced apart. This gap provides sufficient space for subsequent concrete casting, and the concrete can be fully filled into the steel bar connection position and the gap between the movable sub-plate 114 and the lower sub-plate 113. Compared with the traditional floor structure, the present invention ensures that the concrete casting is more dense and uniform, better wraps the steel bar connection position, and enhances the bonding force between the steel bar and the concrete, thereby greatly improving the stability of the entire floor structure connection.

[0028] Working principle: When the prefabricated modular floor structure 1 is hoisted and dropped for installation, the floor will generate downward pressure on the pressure plate 1132 at the bottom of the lower sub-plate 113 under the action of its own gravity. Since the pressure plate 1132 is fixedly connected to the rubber pushing piston 1133, the pressure plate 1132 will drive the rubber pushing piston 1133 to move upward in the isolation sleeve 1134. Fluid material (such as polyurethane sealant, silicone sealant, acrylic sealant, etc.) is stored between the rib bending piston 1136 and the rubber pushing piston 1133 in the isolation sleeve 1134. The upward movement of the rubber pushing piston 1133 will push the fluid material, causing the fluid material to generate pressure and act on the rib bending piston 1136. The rib bending piston 1136 moves upward under the push of the fluid pressure. The upper reinforcement 111 is moved to support the upper reinforcement 111 upwards. Because the upper reinforcement 111 located in the main body 11 of the floor slab has a certain movable space (achieved by an open groove on the surface of the main body 11 of the floor slab for facilitating the upper reinforcement 111 to bend upwards), when the upper reinforcement 111 is subjected to the upward supporting force of the reinforcement bending piston 1136, the upper reinforcement 111 will bend upwards. At this time, the upper part of the reinforcement mesh originally formed by the upper reinforcement 111 and the lower reinforcement 112 will unfold to form an entrance for subsequent reinforcement placement. At the same time, the upper reinforcement 111 will drive the coordinated reinforcement 1111 to rotate, and the coordinated reinforcement 1111 will move into the anti-slip seat provided by the support sleeve 1122 facing the coordinated reinforcement 1111 during the rotation process, and then The rear cooperative reinforcement 1111 will push the support sleeve 1122 upward during the rotation and upward movement, and then the support sleeve 1122 will move up with the cooperative reinforcement 1111 and stretch the telescopic sleeve 1121. Then the construction workers carry the steel bars that need to be introduced and use the entrance formed above the steel mesh to stably lower the steel bars into the steel mesh. Under normal circumstances, four or five steel bars can be introduced to meet the needs of structural connection and reinforcement. After the steel bars are introduced, one of the steel bars is stably placed on the elastic rib plate 1123. When the steel bars are placed on the elastic rib plate 1123, pressure is generated on the support sleeve 1122 through the elastic rib plate 1123. The support sleeve 1122 then cooperates with the anti-slip holder to push the cooperative reinforcement 1111. 1 was bent upward before. Driven by the coordinated pick rib 1111, the upper steel bar 111 gradually returns to its original position. At the same time, after the steel bar is placed inside the elastic rib plate 1123, the elastic rib plate 1123 will be concave under the action of the steel bar's gravity, and then the concave elastic rib plate 1123 will pull and push the two sides of the support sleeve 1122, so that it can hold the steel bar tightly in position with the anti-slip texture on the surface of the elastic rib plate 1123. During the resetting process of the upper steel bar 111, the bending rib piston 1136 will be pushed to move it down along the isolation sleeve 1134. During the downward movement of the bending rib piston 1136, the fluid material will be pushed to further compress the fluid material, and then the pressure inside the isolation sleeve 1134 will increase. At this time,The pressure relief valve 1135 in the isolation sleeve 1134 is opened under the action of the fluid pressure, and the fluid material is discharged into the sealing groove 1131 through the pressure relief valve 1135. As the fluid material is continuously discharged into the sealing groove 1131, the pressure in the sealing groove 1131 gradually increases, which will generate an upward supporting force on the movable sub-plate 114. Because the movable sub-plate 114 is slidably connected to the lower sub-plate 113 through the sealing groove 1131 and the insert 1141, under the top support of the fluid pressure in the sealing groove 1131, the movable sub-plate 114 is The plate 114 will move upward, and finally the upper surface of the movable sub-plate 114 will be flush with the surface of the floor main body 11, so that a certain distance will be generated between the movable sub-plate 114 and the lower sub-plate 113. This distance provides space for the subsequent casting and fixing of concrete, so that the concrete can be fully filled into the steel bar connection part and the gap between the movable sub-plate 114 and the lower sub-plate 113, thereby enhancing the stability of the entire floor structure connection. Then the construction workers can carry out subsequent operations such as tying reinforcement.
