Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and particularly relates to a combined floor support plate construction structure for steel structure buildings. BACKGROUND

[0002] In industrial and civil buildings, the roof of a steel structure building is constructed by using a combined floor support plate, and the combined floor support plate is used as a permanent formwork of a concrete floor in the construction of a steel structure building project, which can not only improve the bonding strength of the concrete, but also improve the bearing capacity of the combined floor support plate construction structure.

[0003] In actual construction, the combined floor support plate construction structure is generally directly placed on a steel structure beam, and a plurality of floor support plates are welded and connected by using welding equipment, so as to support the roof of the steel structure by the floor support plates, thereby providing a bearing foundation for subsequent pouring and construction of the concrete. Since the floor support plate is not a flat structure, when the floor support plate is directly used to bear the concrete, the hollow structure of the floor support plate is easily deformed or even crushed under the pressure of the concrete or other components above, which has a safety hazard. SUMMARY

[0004] The present application solves the technical problem of providing a combined floor support plate construction structure for steel structure buildings, which has strong structural stability and high bearing strength.

[0005] To solve the above technical problems, the technical solution adopted by the present application is as follows: a combined floor support plate construction structure for steel structure buildings, comprising a steel beam frame, a cross beam, a steel secondary beam and a floor support plate assembly. The cross beam is fixed horizontally on the top of the steel beam frame, and the steel secondary beam is supported on the bottom of the cross beam. The floor support plate assembly comprises a plurality of floor support plate bodies arranged on the top of the cross beam and connected in sequence. The floor support plate body is a plate structure with concave and convex portions arranged in sequence. A leakage-proof partition plate is arranged between the floor support plate assembly and the cross beam, and a compression-resistant assembly is arranged between the convex portion of the floor support plate body and the leakage-proof partition plate. The convex portion of the floor support plate body is supported by the compression-resistant assembly, which is used to bear the convex portion of the floor support plate body that is prone to deformation, thereby improving the strength of the convex portion of the floor support plate body and preventing the floor support plate body from being deformed under pressure. The leakage-proof partition plate is used as the installation and fixing base of the compression-resistant assembly, which provides a stable support base for the compression-resistant assembly. In addition, the leakage-proof partition plate can also prevent the subsequent poured concrete from leaking, which is more conducive to the formation of the concrete layer.

[0006] As an improvement to the above solution, the anti-compression component includes a support plate and two rotating clamps rotatably connected to the support plate and arranged opposite to each other. A limiting block is fixed on the inner top surface of the protrusion of the floor decking body; at least two rotating clamps can rotate relative to the support plate and clamp onto the side of the limiting block. The anti-compression component in this invention achieves top support at the protrusion of the floor decking body through the cooperation of the rotating clamps and the limiting block. After the floor decking component is installed, the rotating clamps can be rotated relative to the support plate to clamp onto the limiting block, forming a limiting and fixing effect. The rotating clamps support the inner top surface of the protrusion of the floor decking body, reinforcing it, thereby achieving anti-compression support and deformation-preventing limiting for the floor decking body.

[0007] As an improvement to the above solution, the anti-pressure component further includes a threaded sleeve, a fixing screw, and a connecting rod. The fixing screw passes through the leak-proof partition and the support plate in sequence and extends into the protrusion of the floor deck body. The threaded sleeve is fitted onto the fixing screw and threadedly engages with it. The connecting rod corresponds one-to-one with the rotating clamp. The connecting rod is positioned between the rotating clamp and the threaded sleeve, and both ends of the connecting rod are rotatably connected to the threaded sleeve and the corresponding rotating clamp, respectively. In this invention, the rotation of the rotating clamp is achieved through the cooperation of the threaded sleeve, the fixing bolt, and the connecting rod. By rotating the fixing bolt, the threaded sleeve connected to it can be vertically raised and lowered. The raising and lowering action of the threaded sleeve drives the connecting rod to pull the rotating clamp to rotate relative to the support plate, causing the rotating clamp to open or close. The closing action of the rotating clamp clamps it onto the limiting block. The fixing bolt enables the rotating clamp to support the floor deck body. The operation is simple and convenient, which helps to improve construction efficiency and shorten the construction cycle.

[0008] As an improvement to the above solution, the bottom of the limiting block is provided with a limiting protrusion, and the rotating clamp is inserted into the gap between the limiting protrusion and the protrusion of the floor deck body. In this invention, by adding a limiting protrusion to the bottom of the limiting block, the limiting protrusion and the rotating clamp form a vertical limiting fit, which can further improve the deformation prevention effect of the pressure-resistant component.

[0009] As an improvement to the above solution, adjacent floor decking bodies in the floor decking assembly are engaged by a first toothed plate and a second toothed plate, which are respectively fixed to the two sides of the same floor decking body. In this invention, by setting the connection between the floor decking bodies as an engaging connection, the engagement of the first and second toothed plates improves the connection tightness between adjacent floor decking bodies, achieving a seamless splicing and eliminating the welding steps required in existing floor decking structure connections. Furthermore, the engaging engagement of the first and second toothed plates also facilitates rapid positioning during the assembly of the floor decking assembly, allowing adjacent floor decking bodies to be quickly aligned during assembly, thus improving construction efficiency.

[0010] As an improvement to the above solution, it also includes an insert block, a first limiting groove provided on the toothed shape of the first toothed plate, and a second limiting groove provided on the toothed shape of the second toothed plate. A pressure plate is fixed to the top of the insert block. When the first toothed plate and the second toothed plate mesh, the first limiting groove and the second limiting groove align and form a limiting fit with the insert block. The pressure plate covers the meshing point of the first toothed plate and the second toothed plate. In this invention, by further improving the splicing structure between adjacent floor decking bodies, the limiting groove and the insert block form a limiting fit, which can prevent misalignment of adjacent floor decking bodies under tensile force. At the same time, the pressure plate can press the splicing point of adjacent floor decking bodies, further improving the splicing effect. Furthermore, the pressure plate can also improve the sealing effect of the splicing point of adjacent floor decking bodies, preventing subsequent concrete pouring from leaking from the splicing point.

[0011] As an improvement to the above solution, a reinforcement mechanism is also included. This mechanism consists of an upper support, a lower support, transverse reinforcing ribs, and longitudinal reinforcing ribs. The upper support is fixed to the top surface of the protruding portion of the floor deck slab, and the lower support is fixed to the top surface of the concave portion of the floor deck slab. The upper support is sleeved on the longitudinal reinforcing ribs, and the transverse reinforcing ribs are arranged perpendicularly and alternately with the longitudinal reinforcing ribs. Both the upper and lower supports are fixedly connected to the transverse reinforcing ribs. This invention, by adding a reinforcement mechanism to strengthen the floor deck slab assembly, can improve the load-bearing capacity of the floor deck slab assembly for the roof of steel structure buildings.

[0012] As an improvement to the above solution, it also includes a concrete layer formed by pouring concrete onto the outside of the floor deck assembly, with the reinforcement mechanism located inside the concrete layer; sealing plates are fixed to both ends of the floor deck body to form a sealed fit with the protrusions of the floor deck body. This invention further improves the load-bearing strength of the floor deck assembly by pouring a concrete layer onto the outside of the floor deck assembly, which, in conjunction with the reinforcement mechanism, forms a high-strength reinforced concrete structure; the sealing plates seal the ends of the floor deck body, preventing concrete from entering the internal space of the protrusions of the floor deck body.

[0013] As an improvement to the above solution, it also includes multiple detachable baffles fixed to the edges of the leak-proof partition, with adjacent baffles forming an interlocking fit through butt grooves and inserts. This invention, by adding baffles to the leak-proof partition to block concrete, facilitates the solidification and shaping of the concrete after pouring; the interlocking fit between adjacent baffles enables rapid assembly, thereby reducing assembly difficulty and improving assembly efficiency.

[0014] As an improvement to the above solution, the top of the baffle is also provided with a slot, and adjacent baffles are connected by engaging with the slot and the anti-loosening block. This invention improves the connection stability between adjacent baffles by adding a slot to the baffle and engaging with the anti-loosening block, preventing the baffles from loosening under the pressure of concrete.

[0015] The beneficial effects of this invention are as follows: By improving the construction structure of the composite floor deck, this invention adds a pressure-resistant component between the floor deck assembly and the leak-proof partition to strengthen and support the hollow part of the floor deck body, thereby improving the strength of the floor deck body at the parts that are prone to deformation, avoiding deformation of the floor deck body due to pressure, and improving the load-bearing capacity of the roof of the steel structure building through the floor deck assembly.

Detailed Implementation

[0025] To facilitate understanding of the present invention, the invention will be further described below with reference to the accompanying drawings.

[0026] In the description of this invention, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0027] like Figure 1 The present invention discloses a composite floor decking construction structure for steel structure buildings, which improves the composition of the floor decking assembly based on the existing structure of steel beam frame 110, crossbeam 120, secondary steel beam 130, and floor decking components. The floor decking assembly is installed on the foundation structure composed of the steel beam frame 110, crossbeam 120, and secondary steel beam 130. The crossbeam 120 is horizontally fixed to the top of the steel beam frame 110, and the secondary steel beam 130 is supported at the bottom of the crossbeam 120. The floor decking assembly, composed of multiple sequentially connected floor decking bodies 200, is laid on top of the crossbeam 120. The floor decking assembly provides a foundation for concrete pouring on the roof of the steel structure building, and its construction also improves the load-bearing capacity of the roof. The improvement of the floor decking assembly in this invention lies in the use of an undulating structure for the floor decking body 200, such as... Figure 1 As shown, the floor decking body 200 has protrusions 210 and recesses 220 arranged at intervals, so that the plate structure of the floor decking body 200 protrudes upward at intervals. At the same time, a leak-proof partition 300 is added between the floor decking assembly and the beam 120, and a pressure-resistant component 400 is added between the protrusions 210 and the leak-proof partition 300 of the floor decking body 200. By using the pressure-resistant component 400, the protrusions 210 of the floor decking body 200, which are prone to deformation under pressure, can be supported and strengthened, thereby improving the strength of the protrusions 210 of the floor decking body 200.

[0028] Specifically, the compressive strength component 400 used in this invention is as follows: Figure 1 and Figure 3As shown, the main structure of the anti-pressure component 400 includes a support plate 410 and a rotating clamp 420. The support plate 410 is fixed on the top surface of the leak-proof partition 300. At least two rotating clamps 420 are rotatably mounted on the support plate 410 via a rotating shaft. The rotating clamps 420 can achieve the folding or opening of the entire rotating clamp structure through the rotation action relative to the support plate 410, similar to a gripper mechanism. At the same time, a limiting block 430 is fixed on the inner top surface of the protrusion 210 of the floor deck body 200. The top of the rotating clamp 420 is provided with a groove that matches the outer peripheral contour shape of the limiting block 430. By rotating the rotating clamp 420 itself, the rotating clamp 420 can be folded toward the limiting block 430, so that the groove on the top of the rotating clamp 420 abuts against the outer peripheral surface of the limiting block 430, thereby clamping the rotating clamp 420 onto the limiting block 430 after folding. In this invention, the rotating clamp 420 and the limiting block 430 in the anti-compression component 400 cooperate to clamp the rotating clamp 420 onto the limiting block 430, while the top of the rotating clamp 420 abuts against the inner top surface of the protrusion 210 on the floor deck body 200. The rotating clamp 420 supports the protrusion 210. The clamping effect of the rotating clamp 420 on the protrusion 210 can be adjusted by adjusting the degree of retraction of the rotating clamp 420. Furthermore, the rotating clamp 420 clamping onto the limiting block 430 forms a limiting fit, which can prevent the protrusion 210 from deforming. Therefore, this invention uses the anti-compression component 400 to achieve the effects of anti-compression support and deformation prevention limiting for the protrusion 210 of the floor deck body 200.

[0029] like Figure 1 and Figure 3 As shown, in this invention, the rotation of the rotating clamp 420 in the anti-pressure component 400 is achieved by the cooperation of the threaded sleeve 440, the fixing screw 450, and the connecting rod 460. The fixing screw 450 passes through the leak-proof partition 300 and the support plate 410 in sequence and then extends into the protrusion 210 of the floor deck body 200. The threaded sleeve 440 is sleeved on the fixing screw 450 and threadedly engaged with the fixing screw 450. The number of connecting rods 460 is the same as that of the rotating clamp 420 and they are in a one-to-one correspondence. The connecting rod 460 is arranged between the threaded sleeve 440 and the corresponding rotating clamp 420. The two ends of the connecting rod 460 are rotatably connected to the threaded sleeve 440 and the corresponding rotating clamp 420 respectively through a rotating shaft. By rotating the fixing screw 450, a relative displacement occurs between the threaded sleeve 440 and the fixing screw 450. The threaded sleeve 440 moves downward along the fixing screw 450, which in turn drives the connecting rod 460 to retract downward, thereby pulling the rotating clamp 420 towards the limiting block 430 and finally clamping it onto the limiting block 430. Conversely, rotating the fixing screw 450 in the opposite direction will pull the rotating clamp 420 to unfold away from the limiting block 430. Furthermore, as... Figure 3As shown, in this invention, a limiting protrusion 431 is added to the bottom of the limiting block 430, so that the limiting block 430 presents an inverted "T" shaped structure. When the rotating clamp 420 is clamped on the side of the limiting block 430, it is inserted into the gap between the limiting protrusion 431 and the protrusion 210 of the floor deck body 200. By setting the limiting protrusion 431 to cooperate with the protrusion 210 of the floor deck body 200 to form a limit above and below the top of the rotating clamp 420, the anti-deformation limiting effect of the anti-compression component 400 on the protrusion 210 of the floor deck body 200 can be further improved.

[0030] In floor decking assemblies, the floor decking body 200 is prone to misalignment between adjacent floor decking bodies 200 due to tensile stress. To address this issue, the structure of the floor decking body 200 is improved in this invention, such as... Figure 4 and Figure 6 As shown, the two sides of the floor deck body 200 are improved from straight edge structure to toothed edge structure, that is, a first toothed plate 230 and a second toothed plate 240 are respectively provided on the two sides of the same floor deck body 200, and the teeth of the first toothed plate 230 and the second toothed plate 240 are in an interlocking relationship. When adjacent floor decking bodies 200 are spliced, the first toothed plate 230 on the edge of one floor decking body 200 engages with the second toothed plate 240 on the edge of the other floor decking body 200, creating a tight fit between the adjacent floor decking bodies 200. The engagement of the first toothed plate 230 and the second toothed plate 240 provides a length-direction limiting effect on the adjacent floor decking bodies 200, preventing misalignment due to tensile forces. This meshing splicing method also eliminates the need for welding, thus saving construction steps. Furthermore, the engagement of the first toothed plate 230 and the second toothed plate 240 allows for rapid positioning of the adjacent floor decking bodies 200 during the assembly of the floor decking components, thereby improving assembly efficiency.

[0031] To further improve the splicing effect between adjacent floor decking bodies 200, the present invention further improves the structure of the first toothed plate 230 and the second toothed plate 240, such as... Figures 4 to 6As shown, a first limiting groove 250 is added to the first toothed plate 230, and a second limiting groove 260 is added to the second toothed plate 240. The positions of the first limiting groove 250 and the second limiting groove 260 are corresponding. When the first toothed plate 230 and the second toothed plate 240 mesh, the first limiting groove 250 and the second limiting groove 260 are connected to form a complete limiting groove structure. At the same time, an insert block 270 that matches the shape of the limiting groove is added. For example, in this invention, the first limiting groove 250 and the second limiting groove 260 are both right-angled triangular grooves, and the outer contour shape of the insert block 270 is the corresponding rectangle. After adjacent floor deck slab bodies 200 are engaged by the first toothed plate 230 and the second toothed plate 240, the insert block 270 is inserted into the limiting groove structure composed of the first limiting groove 250 and the second limiting groove 260 to form an insertion fit. By using the limiting groove structure of the insert block 270 for insertion fit, the connection effect between adjacent floor deck slab bodies 200 can be further strengthened, and the welding splicing process can be reduced. At the same time, a pressure plate 280 is fixed on the top of the insert block 270. After the insert block 270 is inserted into the limiting groove structure, the pressure plate 280 covers the engagement point of the first toothed plate 230 and the second toothed plate 240, thereby blocking the splicing gap between adjacent floor deck slab bodies 200 and preventing concrete from leaking from the splicing gap between adjacent floor deck slab bodies 200 during subsequent concrete pouring.

[0032] like Figure 1 and Figure 3 As shown, this invention adds a reinforcing mechanism above the floor decking assembly. The reinforcing mechanism consists of an upper support 510, a lower support 520, transverse reinforcing ribs 530, and longitudinal reinforcing ribs 540. The upper support 510 is fixed to the top surface of the protrusion 210 of the floor decking body 200, and the lower support 520 is fixed to the top surface of the recess 220 of the floor decking body 200. The upper support 510 is sleeved on the longitudinal reinforcing rib 540. The transverse reinforcing ribs 530 and longitudinal reinforcing ribs 540 are arranged perpendicularly and alternately. Both the upper support 510 and the lower support 520 are fixedly connected to the transverse reinforcing ribs 530. The upper support 510, lower support 520, transverse reinforcing ribs 530, and longitudinal reinforcing ribs 540 can all be made of steel reinforcement, and the connections between them are made by welding. On the outside of the floor decking assembly, as shown... Figure 1 and Figure 2 The floor deck assembly shown is formed by pouring concrete to create a concrete layer 600. The aforementioned reinforcement mechanism is located inside the concrete layer 600. Together with the concrete layer 600, the reinforcement mechanism forms a reinforced concrete structure that provides good reinforcement. Sealing plates 700 are welded to the openings at both ends of the floor deck body 200 to seal the two ends of the protrusions 210 of the floor deck body 200. This prevents concrete material from entering the interior of the floor deck body 200 from the openings at both ends of the protrusions 210 during concrete pouring, thereby reducing the amount of concrete used.

[0033] To facilitate the solidification and shaping of the 600mm concrete layer, such as Figure 1 As shown, this invention adds a baffle 800 to the edge of the leak-proof partition 300 to form edge protection. The baffle 800 and the leak-proof partition 300 together block the poured concrete, preventing it from overflowing after pouring and facilitating vibration and smoothing work by workers after pouring. In this invention, the baffle 800 is detachably installed on the edge of the leak-proof partition 300 for easy installation and removal. Specifically, as... Figure 7 and Figure 8 As shown, mating grooves 810 and insert strips 820 are respectively provided on both sides of the baffle 800. When adjacent baffles 800 are spliced, they form an insert fit through the mating grooves 810 and insert strips 820. Simultaneously, a locking groove 830 is provided on the top of the baffle 800. After adjacent baffles 800 are spliced, anti-loosening blocks 840 are inserted into the slots formed by the locking grooves 830 on the adjacent baffles 800 to form a snap-fit ​​fit. Figure 8 As shown, the anti-loosening block 840 in this invention adopts a structure similar to a dumbbell, with large ends and a small middle. However, the anti-loosening block 840 is locked in the slot 830 of the adjacent baffle 800.
