Description

Technical Field

[0001] This utility model belongs to the field of support structure technology, specifically relating to a temporary support structure used in the construction of prefabricated floor decking. Background Technology

[0002] In large-span steel structure prefabricated buildings, temporary supports are needed at the bottom of the upper floor slab after it has been laid and before concrete pouring to prevent mid-span collapse due to the large floor span. Existing patent application number CN202111159591.3, entitled "A Construction Method for Large-Span Steel Truss Floor Slabs in Steel Structures," discloses a support system for supporting the upper floor slab in large-span steel structure prefabricated buildings. This patent application relies on a steel truss structure... The use of top-supporting wooden planks (beams) to support large-span floor decking has the advantage of being simple to construct, relying solely on steel bars and ties. However, it has the disadvantage of being time-consuming to construct and inconvenient to install the top-supporting wooden planks (beams) between the truss and the floor decking. It requires hoisting after the truss is constructed, which also poses certain safety risks. Therefore, to address the shortcomings of existing technologies, developing a temporary support structure for prefabricated floor decking construction is in line with practical needs.

[0008] Furthermore, the hydraulic push rod module includes a hydraulic push rod and a push plate. The hydraulic push rod is fixed to the top of the base plate module by a mounting seat, and the piston rod end of the hydraulic push rod is set towards the end of the base plate module. The push plate is fixedly installed on the piston rod end of the hydraulic push rod, and both ends of the push plate extend along the width direction of the base plate module and are respectively fixedly connected to the adjacent bottom sliding blocks in the two support components.

[0009] Furthermore, the longitudinal reinforcement assembly includes two longitudinal reinforcement modules, which are symmetrically arranged between the bottom plate module and the top mounting plate along the centerline of the length direction of the top mounting plate.

[0012] The beneficial effects of this application compared to the prior art are:

[0013] This application provides a temporary support structure for prefabricated floor decking construction. It employs an X-shaped extension structure combined with a hydraulic drive device as the main support, and reinforces the main support with supporting columns to ensure the stability of the support system. Compared to traditional steel truss structures, the support structure provided in this application can actively adjust the longitudinal height of the top support plank (beam). Utilizing a pushing structure constructed with hydraulic pushers and the X-shaped extension structure, the top support plank (beam) can be directly pushed to the bottom area of ​​the upper floor decking, eliminating the need for high-altitude installation by construction personnel. Furthermore, no other hoisting structure is required during the lifting of the top support plank (beam), greatly improving the safety and convenience of temporary support construction. Compared to traditional temporary support, the construction period is shortened by 30%-35%. Attached Figure Description

[0028] Specific implementation method one: Combining Figures 1 to 13 This embodiment describes a temporary support structure used in the construction of prefabricated floor decking. The temporary support structure includes multiple temporary support units, which are sequentially arranged between the upper floor decking and the lower floor decking along the length of the support area. Adjacent temporary support units are connected by bolts, and the upper floor decking is temporarily supported during construction by the multiple temporary support units.

[0029] The temporary support unit includes a top support beam module 11, a support beam limiting component, a lifting component, and a longitudinal reinforcement component. The lifting component is located between the upper floor deck and the lower floor deck. The top support beam module 11 is installed on top of the lifting component through the support beam limiting component. The longitudinal reinforcement component is located in the lifting component to support and reinforce the lifting component. A connecting part is provided on the outer wall at both ends of the top support beam module 11. The connecting parts of two adjacent top support beam modules 11 are connected by bolts.

[0030] In this embodiment, the main material of the top support beam module 11 can be a wooden beam or a hollow metal tube beam. The connecting part at its end is a rectangular metal connecting flange. It is worth noting that the metal connecting flange has a three-sided structure. No connecting part is provided on the support surface of the top support beam module 11. If the top support beam module 11 is a wooden beam, its end is processed with an embedding groove for installing the rectangular metal connecting flange and is fastened with bolts. If the top support beam module 11 is a wooden beam or a hollow metal tube beam, the rectangular metal connecting flange can be directly welded to its outer wall.

[0031] The modular construction system provided in this application has good versatility. Whether it is for flat floor decking or sloping floor decking, the number and height of temporary support units can be reasonably arranged according to the support needs. With the cooperation of the top support beam module 11 corresponding to the support surface, temporary stable support can be achieved. The main support and the top support beam module 11 can be lifted to the target support area and closely contacted with the upper floor decking through the lifting component, which improves the convenience and safety of construction and greatly shortens the construction period.

[0032] Specific Implementation Method Two: Combining Figures 1 to 13 This embodiment differs from specific embodiment one in that the supporting assembly includes a base plate module 1, a top mounting plate 7, a hydraulic push rod module, and two support modules. The base plate module 1 is positioned on top of the lower floor slab. The top mounting plate 7 is positioned parallel to each other above the base plate module 1. The two support modules are positioned opposite each other along the centerline of the width direction of the top mounting plate 7 between the base plate module 1 and the top mounting plate 7. The top of the support modules is fixedly connected to the bottom of the top mounting plate 7, and the bottom of the support modules is fixedly connected to the top of the base plate module 1. The hydraulic push rod module is fixed to the top of the base plate module 1, and its movable end is connected to the lower part of the two support modules. The hydraulic push rod module acts as a power source to drive the two support modules to synchronously extend and retract. Other components and connection methods are the same as in specific embodiment one.

[0033] Specific implementation method three: Combining Figures 1 to 13 This embodiment differs from specific embodiment two in that the support module includes a lower slide rail 2, an X-extension structure 4, and an upper slide rail 6. The lower slide rail 2 is fixed to the top of the base plate module 1 along its length, and the upper slide rail 6 is fixed to the bottom of the top mounting plate 7 along its length. The lower slide rail 2 and the upper slide rail 6 are arranged parallel to each other vertically. The X-extension structure 4 is arranged vertically between the lower slide rail 2 and the upper slide rail 6. The two legs at the bottom of the X-extension structure 4 are slidably connected to the lower slide rail 2 via a bottom sliding block 3, and the two legs at the top of the X-extension structure 4 are slidably connected to the upper slide rail 6 via a top sliding block 5. Other components and connection methods are the same as in specific embodiment two.

[0034] Specific implementation method four: Combination Figures 1 to 13 This embodiment differs from Specific Embodiment Three in that the hydraulic push rod module includes a hydraulic push rod 8 and a push plate 9. The hydraulic push rod 8 is fixed to the top of the base plate module 1 via a mounting base, and the piston rod end of the hydraulic push rod 8 faces the end of the base plate module 1. The push plate 9 is fixedly installed on the piston rod end of the hydraulic push rod 8, and both ends of the push plate 9 extend along the width direction of the base plate module 1 and are respectively fixedly connected to the adjacent bottom sliding blocks 3 in the two support components. Other components and connection methods are the same as in Specific Embodiment Three.

[0035] Referring to specific embodiments two to four, the lifting component is an important part of this application. Its core function is to change the extension state of the X-extension structure 4 using a hydraulic push rod 8 as a power source, thereby achieving a lifting action on the top support beam module 11. The top mounting plate 7 has a limiting slot machined on its top for installing the top support beam module 11. This limiting slot accurately positions the top support beam module 11, ensuring accurate installation. Simultaneously, the length of the top mounting plate 7 is shorter than the length of the top support beam module 11, ensuring that both ends of the top support beam module 11 can extend beyond the top mounting plate 7, providing working space for subsequent beam connection. For ease of transportation, both the base plate module 1 and the top mounting plate 7 can adopt a modular assembly design. The top mounting plate 7 can be divided into two equal parts along its width centerline. Each part has a limiting semi-groove structure machined on its top inner side to accommodate the support beam module 11, and each part has an installation groove at its bottom. Threaded holes are used to install the upper slide rail 6. At the same time, threaded holes are machined at both ends of the bottom of each part for installing the longitudinal reinforcement module 10. If necessary, a plug-in structure can also be set on the inner side of each part for subsequent assembly and positioning. Each part can be transported separately and then assembled on the construction site. The base plate module 1 can be disassembled into two sliding mounting plates 1-1, one hydraulic push rod module mounting plate 1-2, and two longitudinal reinforcement module mounting plates 1-3. The two sliding mounting plates 1-1 are arranged in parallel opposite directions. The top of each sliding mounting plate 1-1 is provided with a mounting groove and threaded holes for installing the lower slide rail 2. One hydraulic push rod module mounting plate 1-2 is inserted into the middle between the two sliding mounting plates 1-1 and is used to install the hydraulic push rod 8. The two longitudinal reinforcement module mounting plates 1-3 are arranged opposite each other on both sides of the hydraulic push rod module mounting plate 1-2, and each longitudinal reinforcement module mounting plate 1-3 is inserted into the end of the two sliding mounting plates 1-1. The longitudinal reinforcement module mounting plate 1-3 is used to install the longitudinal reinforcement module 10.

[0036] Setting up two support modules helps ensure the stability of the lifting component during operation, preventing the top support beam module 11 from tilting. Furthermore, during the lifting process, the lifting component only needs to overcome the weight of the top support beam module 11 itself. Whether it is a wooden beam or a hollow tube beam, its own weight is limited, and the power provided by a single hydraulic push rod 8 is sufficient to complete the lifting work.

[0037] Specific Implementation Method Five: Combining Figures 1 to 13 This embodiment differs from Specific Embodiment Four in that the longitudinal reinforcement assembly includes two longitudinal reinforcement modules 10. These two modules 10 are symmetrically arranged between the base plate module 1 and the top mounting plate 7 along the centerline of the top mounting plate 7's length direction. The top end of each longitudinal reinforcement module 10 is detachably connected to the bottom of the top mounting plate 7, and the bottom end of each longitudinal reinforcement module 10 is detachably connected to the top of the base plate module 1. Other components and connection methods are the same as in Specific Embodiment Four.

[0038] Specific Implementation Method Six: Combination Figures 1 to 13 This embodiment differs from specific embodiment five in that the longitudinal reinforcement module 10 includes a bottom connecting flange 10-1, a sleeve 10-2, a locking sleeve 10-3, a plug rod 10-4, and a top connecting flange 10-5. The sleeve 10-2 is vertically positioned on top of the base plate module 1. The bottom connecting flange 10-1 is fitted onto the bottom end of the sleeve 10-2, and the sleeve 10-2 is detachably connected to the base plate module 1 via the bottom connecting flange 10-1. The bottom end of the plug rod 10-4 is vertically inserted into the sleeve 10-2, and the plug rod 10-4 and the sleeve 10-2 are locked and fixed by the locking sleeve 10-3. The top connecting flange 10-5 is fitted onto the top end of the plug rod 10-4, and the plug rod 10-4 is detachably connected to the top mounting plate 7 via the top connecting flange 10-5. Other components and connection methods are the same as in specific embodiment five.

[0039] Referring to the descriptions of specific implementation methods five and six, the longitudinal reinforcement module 10 can be a single fixed-length steel pipe structure or a telescopic sleeve structure with a locking part. The difference between the two is that the telescopic sleeve structure is more flexible in use and can be used with the lifting component for temporary support at different heights. At the same time, the length of the telescopic sleeve structure is adjustable, which facilitates storage and transportation. If a fixed-length steel pipe structure is used, flanges are fitted at both ends and the flanges are used to detach and connect to the bottom module 1 or the top mounting plate 7. If a telescopic sleeve structure is used, the top end of the sleeve 10-2 is designed as a tapered structure. Multiple grooves are machined equidistantly along the circumference of the tapered structure, which divides the tapered structure into multiple clamping grippers. At the same time, external threads are machined at the bottom of the tapered structure for threaded fixation with the locking sleeve 10-3. The shape of the locking sleeve 10-3 is similar to that of the sleeve. The top end of tube 10-2 has the same shape. The inner wall of locking sleeve 10-3 is machined with internal threads that mate with external threads. The shape of the tapered opening at the top of sleeve 10-2 is adjusted by locking the locking sleeve 10-3 with the sleeve 10-2. When it is necessary to adjust the length of insert rod 10-4, locking sleeve 10-3 is in a relaxed state, and the tapered opening is in an expanded state. Insert rod 10-4 can slide back and forth inside sleeve 10-2. When it is necessary to tighten insert rod 10-4, locking sleeve 10-3 with the sleeve 10-2 is used. Under the constraint of locking sleeve 10-3, the tapered opening is in a contracted state and tightly clamped onto insert rod 10-4, thereby achieving a locked fixation to ensure the stability of the longitudinal reinforcement module 10. Both bottom connecting flange 10-1 and top connecting flange 10-5 are provided with reinforcing ribs distributed along the circumference to reinforce the flange body.

[0040] Specific implementation method seven: Combination Figures 1 to 13 This embodiment differs from Specific Embodiment Six in that the support beam limiting assembly includes two support beam limiting module groups, which are arranged opposite each other on both sides of the top support beam module 11. Each support beam limiting module group includes multiple support beam limiting modules 12, which are arranged equidistantly along the length of the top support beam module 11. The side of each support beam limiting module 12 is in close contact with the side wall of the top support beam module 11, and the bottom of each support beam limiting module 12 is detachably connected to the top mounting plate 7 by bolts. Other components and connection methods are the same as in Specific Embodiment Six.

[0041] In this embodiment, the support beam limiting module 12 is used to clamp and fix the top support beam module 11. The main body of the support beam limiting module 12 is an L-shaped plate. The horizontal and vertical parts of the support beam limiting module 12 are provided with reinforcing ribs. Two connecting strip holes are machined on the top of the horizontal part of the support beam limiting module 12, and the two connecting strip holes are respectively set on both sides of the reinforcing ribs. The top of the top mounting plate 7 is also machined with multiple threaded holes for installing the support beam limiting module 12. Each threaded hole is corresponding to a connecting strip hole. The horizontal part of the support beam limiting module 12 is connected to the top mounting plate 7 by bolts. The vertical part of the support beam limiting module 12 is used to make close contact with the top support beam module 11. The top support beam module 11 is clamped and fixed by the support beam limiting modules 12 on both sides.

[0042] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0043] Working principle

[0044] The various components are transported to the supporting floor and assembled according to the contents of Specific Implementation Methods 1 to 7. The first component assembled is the base plate module 1. After the base plate module 1 is assembled, multiple assembled base plate modules 1 are laid in the supporting area according to the pre-designed number and arrangement direction. After the base plate modules 1 are laid, the support module and hydraulic push rod module are installed on the base plate modules 1. After installation, the hydraulic push rod module is adjusted to ensure accurate connection with the support module and to drive the support module to perform longitudinal extension and retraction. It is worth noting that to ensure the support structure can extend and retract stably, the bottom sliding block 3 in the support module, which is not connected to the push plate 9, is fixedly connected to the lower slide rail 2. Simultaneously, the top sliding block 5, located on the same side, is also fixedly connected to the upper slide rail 6. After the support module is installed, the support module... A top mounting plate 7 is installed on top of the block. After the top mounting plate 7 is installed, the top support beam module 11 is embedded in the top mounting plate 7. At this time, adjacent top support beam modules 11 are fastened together with bolts, so that multiple top support beam modules 11 are combined to form a support beam. After multiple top support beam modules 11 are assembled, the multiple top support beam modules 11 are clamped and limited to the corresponding top mounting plate 7 by the support beam limiting module 12. At this time, the hydraulic push rods 8 in multiple temporary support units work synchronously to push the support beam to the top of the support area and make close contact with the upper floor deck. After the support beam makes contact with the upper floor deck, two longitudinal reinforcement modules 10 are set between the bottom plate module 1 and the top mounting plate 7, and the longitudinal reinforcement modules 10 are supported and reinforced with the bottom plate module 1 and the top mounting plate 7 by bolts to complete the construction of the temporary support structure.
