[0002] Prefabricated floor decking is an important building material, composed of steel bars, I-shaped steel, galvanized steel and other materials. It has the advantages of high mechanical strength, high durability and fire resistance. Prefabricated floor decking is easy to install, has fast construction speed and low cost, and is widely used in various industrial and civil buildings.

[0003] The existing floor deck support frame used in the prefabricated steel structure project is usually an integrated steel frame formed by welding, which plays a role in supporting the stability of the floor deck and ensures the stability and safety of the floor deck during use.

[0004] However, the existing floor deck support frame used in prefabricated steel structure projects has the following shortcomings: When in use, the existing floor deck support frame can only support the left and right ends of the floor deck, and cannot provide effective support for the middle part of the floor deck. As a result, the floor deck may break due to excessive force in the middle part during use, which poses a major safety hazard, easily affects the progress of construction, and is difficult to meet actual use needs.

DETAILED DESCRIPTION

[0020] 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 implementation regulations described 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.

[0021] Please see attached Figure 1 -Attached Figure 8As shown, the present invention provides a technical solution: a floor deck support frame used in an assembled steel structure project, comprising a plurality of telescopic columns 1, a bottom mold bracket 2 is fixedly installed on the top of the plurality of telescopic columns 1, a middle support mechanism 3 is arranged on the top of the bottom mold bracket 2, and an end limit mechanism 4 is arranged at one end of the middle support mechanism 3; A connecting crossbeam 5 is fixedly connected between every two telescopic columns 1, and two driving mechanisms 6 are arranged on the top of the connecting crossbeam 5. A locking mechanism 7 is arranged at one end of each driving mechanism 6, and an auxiliary lifting mechanism 8 is arranged inside each driving mechanism 6; The middle support mechanism 3 includes two limit frames 301, and the two limit frames 301 are fixedly installed on the top of the bottom mold bracket 2. The outer sides of the two limit frames 301 are slidably installed with support templates 302. The two ends of the bottom of the support template 302 are rotatably connected to two first connecting rods 303, one end of each first connecting rod 303 is rotatably connected to a first sliding seat 304, and the outer side of each first sliding seat 304 is provided with a first limiting rail 305, and each first limiting rail 305 is fixedly installed on the top of the bottom mold bracket 2. Through the setting of the middle support mechanism 3, the support template 302 is used to provide a stable supporting force for the middle part of the floor decking plate, and at the same time, the support template 302 is limited in cooperation with the limit frame 301 to prevent the supporting force from being offset, thereby improving the stability of the overall support frame during use, and preventing the floor decking plate with a larger net span from bending or breaking due to excessive force in the middle, thereby ensuring the safety of the floor decking plate during construction, improving the progress of the overall construction, and meeting actual use needs.

[0022] according to Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the end limiting mechanism 4 includes two fixed seats 401, and the two fixed seats 401 are fixedly installed at the two ends of the top of the bottom mold bracket 2 respectively, and two brackets 402 are fixedly installed at the two ends of the top of each fixed seat 401, and a fixed shaft 403 is connected between every two brackets 402, and four rotating seats 404 are rotatably installed on the outer side of each fixed shaft 403, and one end of each of the four rotating seats 404 is fixedly connected to an L-shaped frame 405, and the bottom of one end of each L-shaped frame 405 is rotatably connected to a second connecting rod 406, and one end of each second connecting rod 406 is rotatably connected to a corresponding first sliding seat 304. Through the setting of the end limiting mechanism 4, the L-shaped frame 405 can be used to provide a stable supporting force for the left and right ends of the floor deck, and at the same time, the floor deck can be supported. The left and right ends of the plate are limited to prevent the floor decking plate from shaking during construction, thereby further improving the overall stability of the support frame and improving the safety of the support frame when in use. At the same time, the middle support mechanism 3 and the end limiting mechanism 4 cooperate to convert the gravity of the floor decking plate body into a driving force, prompting the rotating seat 404 to drive the L-shaped frame 405 to rotate on the fixed axis 403, providing support for the left and right ends of the floor decking plate and limiting it. At the same time, affected by the gravity of the floor decking plate body, the first sliding seat 304 slides in the first limiting track 305, driving the supporting template 302 to slide and rise on the limiting frame 301, providing a stable supporting force for the middle part of the floor decking plate body. The linkage between the two is relatively close, which effectively reduces the difficulty of using the entire support frame.

[0023] according to Figure 2 and Figure 7 As shown, the driving mechanism 6 includes a second limiting rail 601, which is fixedly installed on the top of the connecting beam 5. A screw rod 602 is arranged inside the second limiting rail 601, and a connecting shaft 603 is arranged at one end of the second limiting rail 601. One end of the connecting shaft 603 is fixedly connected to an operating hand wheel 604, and the other end of the connecting shaft 603 is movable through the second limiting rail 601 and connected to the screw rod 602. By setting up the driving mechanism 6, the operator can drive the rotation of the screw rod 602 by operating the hand wheel 604. This process provides a stable and reliable driving force for the lifting and lowering of the support frame. This design ensures that the support frame can maintain a high degree of stability during the lifting movement, thereby greatly improving the ease of operation. In addition, this design also effectively reduces the dependence on external force drive, saves valuable time cost, and makes the entire operation process more efficient and economical.

[0024] according to Figure 2 and Figure 7As shown, the auxiliary lifting mechanism 8 includes two second sliding seats 801, and the two second sliding seats 801 are both arranged on the outside of the screw rod 602. A first ear seat 802 is fixedly installed on the top of each second sliding seat 801. A third connecting rod 803 is rotatably connected inside each first ear seat 802. One end of each third connecting rod 803 is rotatably connected to a second ear seat 804. Each second ear seat 804 is fixedly installed at the bottom of the bottom mold bracket 2. Through the setting of the auxiliary lifting mechanism 8, we can utilize the rotation of the third connecting rod 803 in the first ear seat 802 and the second ear seat 804. Movement provides an additional stable auxiliary supporting force for the lifting process of the support frame. This design significantly improves the stability of the support frame during the lifting process and ensures smooth lifting action. In addition, it effectively reduces the difficulty during operation, thereby saving manual labor and time costs. Through the ingenious cooperation of the telescopic column 1 and the auxiliary lifting mechanism 8, we can achieve stable and smooth lifting action of the support frame, further enhancing the overall stability of the support frame. At the same time, this design also allows the user to flexibly adjust the height of the support frame to adapt to various different usage scenarios and needs.

[0025] according to Figure 2 and Figure 8 As shown, the locking mechanism 7 includes a fixed frame 701, which is fixedly mounted on one end of the second limiting track 601, and a fixed block 702 is arranged inside the fixed frame 701, one end of the fixed block 702 is connected to two guide rods 703, and a sliding block 704 is slidably mounted on the outer sides of the two guide rods 703, and an extrusion bolt 705 is arranged on the top of the fixed frame 701, and one end of the extrusion bolt 705 is movably passed through the fixed frame 701 and fits on one end of the sliding block 704. Through the setting of the locking mechanism 7, combined with the ingenious cooperation between the fixed frame 701 and the sliding block 704, the connecting shaft 603 can be effectively and firmly locked. The implementation of this mechanism can effectively prevent the operating hand wheel 604 from unnecessary spinning during use. In this way, the overall stability and safety of the support frame are greatly improved, thereby effectively avoiding potential safety hazards, which not only ensures the safety of equipment during construction, but also is an important guarantee for the life safety of construction personnel.

[0026] according to Figure 1 and Figure 4As shown, four dampers 9 are fixedly installed on the top of the bottom mold bracket 2, and a spring 10 is sleeved on the outside of each damper 9. A rubber pad 11 is fixedly connected to the top of every two dampers 9. The combined configuration of the dampers 9 and the springs 10 can effectively absorb and reduce the vibration force borne by the floor deck during the construction process, thereby ensuring the stability of the floor deck. In addition, by using the rubber pad 11 as a support, the friction between the floor deck and the floor deck can be effectively increased, thereby providing additional support for the floor deck. This design enables the force to be evenly dispersed to various parts of the floor deck body when the floor deck is subjected to external force, effectively avoiding the bending or fracture of the floor deck caused by excessive local force. Such a structural design not only improves the safety of the building structure, but also helps to speed up the overall progress of the construction and ensure construction efficiency and quality.

[0027] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, U-shaped frames 12 are symmetrically arranged at both ends of the bottom mold bracket 2 and each L-shaped frame 405, and a limiting plate 13 is inserted into the inner side of each two U-shaped frames 12, and a pull ring 14 is fixedly installed on the top of each limiting plate 13. Through the combined configuration of the U-shaped frame 12 and the limiting plate 13, the two parts of the structure cooperate with each other and work together. With the assistance of the end limiting mechanism 4, they can provide stable support and precise limiting to the left and right ends of the floor decking. At the same time, they can also effectively limit the front and rear ends of the floor decking to ensure that the position of the floor decking is accurate during the installation process. The realization of this linkage mechanism enables the four corners of the floor decking to be limited synchronously, which greatly enhances the stability of the floor decking during the construction process. Such a design not only improves the construction efficiency, but also significantly improves the safety of the support frame in actual application, ensuring the safety of construction personnel and the reliability of construction quality.

[0028] according to Figure 1 , Figure 2 and Figure 3As shown, a base 15 is fixedly installed at the bottom of each telescopic column 1, and a plurality of insertion rods 16 are arranged at the bottom of each base 15. Through the arrangement of the base 15, the contact area between the support frame body and the ground can be significantly increased, thereby effectively improving the overall stability of the support frame. This design takes into account various external forces that may be encountered during the construction process, and ensures that the support frame can remain stable when facing these forces. In addition, by arranging the insertion rods 16 so that they can be inserted into the ground, the fixing effect of the support frame is further enhanced, and the shaking caused by external forces is effectively prevented. Such a design not only ensures the accuracy of construction and ensures the construction quality, but also greatly improves the safety and stability during the construction process, providing a safer and more reliable working environment for construction personnel.

[0029] according to Figure 1 , Figure 2 and Figure 3 As shown, stiffening ribs 18 are fixedly installed at both ends of the top of each connecting beam 5, and one end of each stiffening rib 18 is fixedly connected to a corresponding telescopic column 1. By providing the stiffening ribs 18, the connection strength between the connecting beam 5 and the telescopic column 1 can be significantly enhanced. This structural optimization helps to prevent the support frame body from producing unnecessary deformation when subjected to various external forces, thereby ensuring the stability and reliability of the support frame. Through such improvements, not only the overall performance of the support frame is improved, but also its service life is effectively extended, ensuring the economy and safety of long-term use.

[0030] according to Figure 1 , Figure 4 and Figure 5 As shown, a plurality of anti-skid pads 17 are arranged on the top of the supporting formwork 302, and the tops of the plurality of anti-skid pads 17 are on the same horizontal plane as the tops of the rubber pads 11. By providing the anti-skid pads 17, the friction coefficient between the supporting formwork 302 and the floor decking can be significantly improved, thereby providing the floor decking with a more stable and less prone to displacement middle support force. This design not only ensures the stability of the structure, but also reduces the safety hazards caused by unstable support during the construction process, thereby improving the construction efficiency and quality.

[0031] Working principle: First, transport the support frame as a whole to the designated location, and insert the insertion rod 16 into the ground, so that the base 15 contacts the ground, so that the telescopic column 1 is fixed at the target position, and then, use bolts to install the various parts of the support frame as a whole, so that the support frame is formed as a whole.

[0032] During the floor decking placement stage, the floor decking to be used is hoisted and placed above the support frame. Under the gravity of the floor decking, the rotating seat 404 rotates outside the fixed axis 403 and drives the L-shaped frame 405 to rotate synchronously, and the L-shaped frame 405 supports and limits the left and right ends of the floor decking. At the same time, under the influence of the rotation force, the second connecting rod 406 rotates and pushes the first sliding seat 304 to slide in the first limiting track 305. At this time, under the thrust, the first connecting rod 303 rotates and drives the supporting template 302 to slide and rise outside the limiting frame 301, so that the anti-slip pad 17 fits the bottom of the floor decking and provides stable support for the middle of the floor decking. Then, the pull ring 14 is grasped, and the limiting plate 13 connected thereto is inserted into the corresponding U-shaped frame 12 in turn, so that the limiting plate 13 and the L-shaped frame 405 cooperate with each other, and then the four corners of the floor decking are limited to ensure that it is not easy to shake due to external forces.

[0033] During the lifting and lowering adjustment stage, the two operating hand wheels 604 are turned to drive the corresponding connecting shafts 603 to drive the screw rod 602 to rotate, causing the second sliding seat 801 to slide on the outside of the screw rod 602. The force generated by the sliding causes the two ends of the third connecting rod 803 to rotate in the first ear seat 802 and the second ear seat 804 respectively, thereby causing the third connecting rod 803 to cooperate with the telescopic column 1, driving the support frame as a whole to adjust its height, so that it drives the floor decking plate to rise to a suitable height.

[0034] During the shaft locking stage, the extrusion bolt 705 is turned so that one end of the extrusion bolt 705 pushes the sliding block 704 to slide on the guide rod 703. At this time, the sliding block 704 and the fixed block 702 gradually approach each other, generating a strong extrusion force, which acts on the connecting shaft 603 and then locks it to prevent the connecting shaft 603 and the operating hand wheel 604 from spinning, thereby ensuring the overall stability of the support frame.

[0035] In the balance and shock absorption stage, during the construction process, when the floor deck is vibrated by external force, the damper 9 and the spring 10 cooperate with each other to absorb and reduce the vibration force, thereby maintaining the overall stability of the support frame. At the same time, the rubber pad 11 can fit on the bottom of the floor deck so that the entire floor deck can receive sufficient support force.

[0036] Based on the above contents, the use of the floor deck support frame used in the prefabricated steel structure project can be completed.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
