Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a truss support equipment for supporting steel structure floor slabs and its application method. Background Technology

[0002] In steel structures, profiled steel sheets are widely used as floor slabs. After the profiled steel sheets are laid, before pouring concrete, supports must be placed on the underside of the sheets to ensure stability during the pouring process and good flatness of the floor slab after pouring.

[0003] The current support method mainly involves erecting full-span scaffolding and using top supports. This method requires a significant investment of time and labor in scaffolding installation and dismantling.

[0004] In addition, some projects use steel trusses as the support structure. However, this method requires tower crane hoisting for the entire steel truss erection process, with manual leveling and locking of the support legs using shims. The installation process is cumbersome and occupies tower crane resources. At the same time, workers are working at height with narrow operating areas, posing certain safety risks. Furthermore, after the concrete is poured, it is very inconvenient for workers to loosen the support legs and retrieve the steel truss due to the obstruction of the floor slab.

[0005] In view of the shortcomings of the support methods used in the existing technology for supporting profiled steel sheets, those skilled in the art have been looking for solutions. Summary of the Invention

[0006] The purpose of this invention is to provide a truss support equipment and its application method for supporting steel structure floor decking, so as to solve the shortcomings of the existing support methods for supporting profiled steel sheets, which result in high construction costs and certain construction safety risks.

[0007] To address the aforementioned technical problems, this invention provides a truss support device for supporting steel structure floor slabs. The truss support device comprises: a truss and two support power components, each detachably mounted on two adjacent H-beams. Each support power component includes: a power unit and a support component hoisted onto the power unit. The power unit is detachably mounted on an H-beam. After the support component is hoisted to the working surface under the drive of the power unit, it is connected and installed with the truss. With the cooperation of the support component and the corresponding H-beam, the truss is fixed between the two H-beams to support the steel structure floor slab.

[0008] Optionally, in the truss support equipment for supporting steel structure floor slabs, the power unit includes: a power structure main body, a lifting hoist mounted on the power structure main body, a support leg drive motor, a limit switch, and a control box.

[0009] Once the truss is hoisted to the work surface, the limit switch is triggered; the control box receives the signal from the limit switch to control the working status of the hoist and the support leg drive motor.

[0010] Optionally, in the truss support equipment for supporting steel structure floor slabs, the main power structure includes: a frame body, a support leg drive motor mounting base and a lifting lug disposed on the frame body, a sliding flange plate disposed on the side of the frame body, and locking bolts; wherein, the lifting lug is connected to the lifting hoist; after the sliding flange plate is engaged with the flange of the H-beam on the corresponding side, the locking bolts fix the sliding flange plate to the flange of the H-beam.

[0011] Optionally, in the truss support equipment for supporting steel structure floor slabs, each support component includes: two support leg components, an adjustable component disposed between the two support leg components, and a transmission component, wherein the transmission component is connected to the support leg drive motor of the power device.

[0012] Optionally, in the truss support equipment for supporting steel structure floor slabs, the truss includes: a parallel upper chord and a lower chord, a web member disposed between the upper chord and the lower chord, and two rectangular frames respectively disposed at both ends of the upper chord and the lower chord; wherein each rectangular frame includes: two parallel uprights and two parallel horizontal grooves disposed on the two parallel uprights, the uprights being perpendicular to both the upper chord and the lower chord, the horizontal grooves being perpendicular to the uprights, and the horizontal grooves being parallel to the upper chord.

[0013] Optionally, in the truss support equipment for supporting steel structure floor slabs, each support leg assembly includes: a horizontal support leg and a vertical support leg; wherein, each horizontal support leg includes: a rod and a vertical slide rail disposed at the front end of the rod; each vertical support leg includes: a rod and an ear plate disposed at the lower end of the rod.

[0014] The horizontal support leg can be nested into the horizontal slide groove of the truss to form a horizontal sliding pair; the vertical support leg can be nested into the vertical slide rail of the horizontal support leg to form a vertical sliding pair.

[0015] Optionally, in the truss support equipment for supporting steel structure floor slabs, the adjustable component includes: a slider and two adjustable connecting rods symmetrically distributed relative to the slider; wherein, each adjustable connecting rod includes: a double-ended stud and two lugs respectively disposed at both ends of the double-ended stud; the slider includes: a slider body and two lugs disposed on opposite sides of the slider body; the lugs at both ends of each adjustable connecting rod are respectively hinged to the lugs of the vertical support foot on its adjacent side and the lugs of the slider, and the slider body is fixedly connected to the transmission screw of the transmission component to restrict the rotation of the transmission screw, so that the transmission screw can only move along its axial direction.

[0016] Optionally, in the truss support equipment for supporting steel structure floor slabs, the transmission assembly includes: a power input shaft, a driving bevel gear meshing with the power input shaft, a driven bevel gear meshing with the driving bevel gear, and a transmission screw coaxially connected to the driven bevel gear. The driving bevel gear transmits the torque received from the output shaft of the support foot drive motor to the driven bevel gear through gear meshing, and then to the transmission screw. The transmission screw converts the rotational motion of the driven bevel gear into horizontal linear motion.

[0017] The present invention also provides a method for applying truss support equipment for supporting steel structure floor slabs, the method comprising:

[0018] Adjust two of the two support components in the two support power components according to the cross-sectional dimensions of the H-beams at the construction site;

[0019] The two power units of the two supporting power components are respectively installed and fixed on two adjacent H-shaped steel beams;

[0020] Based on the two power units, the two support components are respectively hoisted and fixed to the working surface;

[0021] Two support components are installed together on both sides of a truss. With the cooperation of the two support components and the H-shaped steel beams on the corresponding sides, the truss is fixed between the two H-shaped steel beams to support the steel structure floor deck.

[0022] Remove the two power units that are fixed to the two H-beams;

[0023] A profiled steel sheet is laid on the fixed truss.

[0024] Optionally, in the application method of the truss support equipment for supporting steel structure floor slabs, the process of fixing the truss support between the two H-beams with the cooperation of the two support components and the H-beams on the corresponding sides includes the following steps:

[0025] Driven by two motors of two power units, the horizontal and vertical support legs of the two support components extend one after another, respectively supporting the web and flange of the H-beam on the corresponding side, so as to fix the truss support between the two H-beams.

[0026] In the truss support equipment and its application method for supporting steel structure floor slabs provided by this invention, the truss support equipment is designed to include: a truss and two support power components, the two support power components being detachably installed on two adjacent H-shaped steel beams; each support power component includes: a power unit and a support component hoisted onto the power unit, the power unit being detachably installed on an H-shaped steel beam; after the support component is hoisted to the working surface under the drive of the power unit, the support component is connected and installed with the truss, and with the cooperation of the support component and the corresponding H-shaped steel beam, the truss support is fixed between the two H-shaped steel beams to support the steel structure floor slab. The entire support and fixing process of supporting the steel structure floor slab is based on the automatic completion of the construction surface positioning and support construction by the power unit and support components, the entire process does not require tower crane hoisting, the installation process of the support equipment is simple, and it saves manpower and material resources. At the same time, the truss support equipment can automatically complete the installation and disassembly as needed, the operation is simple and efficient, and the construction safety risks are reduced.

[0027] On the other hand, the power unit is designed with a pull-out chute structure, namely a chute-type flange clamping structure, to accommodate the installation of steel beams with different flange widths. At the same time, the opening range of the two vertical support legs can be adjusted by adjusting the length of the adjusting link to accommodate steel beams with different cross-sectional dimensions. These two adjustable designs greatly broaden the application range of the support equipment.

[0028] On the other hand, the horizontal and vertical supports of the support assembly adopt a less-than-freedom linkage design. By setting the linkage transmission angle, it is ensured that during the installation of the truss support equipment, the horizontal support extends first, abutting against the web of the H-beam, and then the vertical support extends until it is firmly against the flange of the H-beam. During disassembly, the horizontal and vertical supports move in the reverse order. Based on this design, on the one hand, it can ensure that one power source can drive the orderly movement of both supports, reducing the introduction of redundant power components, lowering manufacturing costs, and facilitating production, assembly, and maintenance. At the same time, the method of extending the horizontal supports first and then retracting the vertical supports first and then retracting them can effectively avoid the flanges, preventing the supports from colliding with the flanges of the H-beam during installation or disassembly, thus improving construction safety.

Detailed Implementation

[0048] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more comprehensive understanding of the truss support equipment for supporting steel structure floor slabs and its application method proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0049] Please refer to Figures 1 to 4 The truss support equipment for supporting the steel structure floor slab includes: a truss 1 and two support power components 2, which are detachably installed on two adjacent H-beams 3 respectively; wherein, each support power component 2 includes: a power device 22 and a support component 21 hoisted on the power device 22, and the power device 22 is detachably installed on an H-beam 3; after the support component 21 is hoisted to the working surface under the drive of the power device 22, the support component 21 is connected and installed with the truss 1, and with the cooperation of the support component 21 and the H-beam 3 on the corresponding side, the truss 1 is supported and fixed between the two H-beams 3 to support the steel structure floor slab.

[0050] Please refer to Figure 6Each support component 21 includes: two support leg components 211, an adjustable component 212 disposed between the two support leg components 211, and a transmission component 213, wherein the transmission component 213 is connected to the support leg drive motor 223 of the power device 22.

[0051] For details, please refer to Figure 7 and Figure 12 The truss 1 includes: a parallel upper chord 11 and a lower chord 12, a web member 13 disposed between the upper chord 11 and the lower chord 12, and two rectangular frames respectively disposed at both ends of the upper chord 11 and the lower chord 12; wherein each rectangular frame includes: two parallel uprights 15 and two parallel horizontal grooves 14 disposed on the two parallel uprights 15, the uprights 15 being perpendicular to both the upper chord 11 and the lower chord 12, the horizontal grooves 14 being perpendicular to the uprights 15, and the horizontal grooves 14 being parallel to the upper chord 11. The truss 1 of the present invention differs from existing trusses by adding two structures, the uprights 15 and the horizontal grooves 14, to facilitate docking and installation with the support assembly 211, thereby achieving docking and installation of the support assembly 21 and the truss 1. The uprights 15 increase the vertical support of the truss 1; the horizontal chute 14 can be used to accommodate the horizontal support legs 2111 and provide guidance for the horizontal support legs 2111. In order to facilitate the hoisting of the truss 1, the truss 1 also includes lifting lugs 16 provided on the upper chord 11.

[0052] Please refer to Figure 10 , Figure 11 and Figure 12 Each support leg assembly 211 includes a horizontal support leg 2111 and a vertical support leg 2112, which are respectively responsible for abutting against the web 31 and flange 32 of the H-beam 3 to complete the installation and fixation of the truss 1. Each horizontal support leg 2111 includes a rod 2111a and a vertical slide rail 2111b disposed at the front end of the rod 2111a. Each vertical support leg 2112 includes a rod 2112a and an ear plate 2112b disposed at the lower end of the rod 2112a. The horizontal support leg 2111 can be nested into the horizontal slide rail 14 of the truss 1 to form a horizontal sliding joint, so that the horizontal support leg 2111 has a degree of freedom in the X direction. The vertical support leg 2112 can be nested into the vertical slide rail 2111b of the horizontal support leg 2111 to form a vertical sliding joint, so that the vertical support leg 2112 has a degree of freedom in the Y direction. The support frame 211 has two degrees of freedom, so there is no need to consider obstacle avoidance during installation. It is a purely mechanical structure, driven by an electric wrench, and can be reused.

[0053] Please refer to Figure 6 and Figure 13The adjustable component 212 includes: a slider 2121 and two adjustable connecting rods 2122 symmetrically distributed relative to the slider 2121; wherein, each adjustable connecting rod 2122 includes: a bidirectional stud 2122a and two ear plates 2122b respectively disposed at both ends of the bidirectional stud 2122a; the slider 2121 includes: a slider body 2121a and two ear plates 2121b disposed on opposite sides of the slider body 2121a; the ear plates 2122b at both ends of each adjustable connecting rod 2122 are respectively hinged to the ear plate 2112b of the vertical support foot 2112 on its adjacent side and the ear plate 2121b of the slider; the slider body is fixedly connected to the transmission screw 2134 of the transmission component 213 to restrict the rotation of the transmission screw 2134, so that the transmission screw 2134 can only move along its axial direction. Specifically, the two ear plates 2122b are respectively tightened to both ends of the double-acting stud 2122a via a nut structure. By rotating the double-acting stud 2122a, the two ear plates 2122b can be extended or retracted simultaneously in two directions. The adjustable connecting rod 2122 is designed in this way to adapt to the installation of H-beams 3 with different cross-sectional dimensions by adjusting the length of the adjustable connecting rod 2122. Preferably, the adjustable component 212 includes two tension springs 2123, which are disposed between the ear plates 2121b and 2112b.

[0054] Please refer to Figure 4 , Figure 6 , Figure 8 and Figure 9 The transmission assembly 213 includes: a power input shaft 2131, a driving bevel gear 2132 meshing with the power input shaft 2131, a driven bevel gear 2133 meshing with the driving bevel gear 2132, and a transmission screw 2134 coaxially connected to the driven bevel gear 2133. The driving bevel gear 2132 transmits the torque received from the output shaft of the support foot drive motor 223 to the driven bevel gear 2133 through gear meshing, and then to the transmission screw 2134. The transmission screw 2134 converts the rotational motion of the driven bevel gear 2133 into horizontal linear motion. Specifically, as shown... Figure 8 and Figure 9 As shown, the driven bevel gear 2133 has a bevel gear body at its front end and a transmission nut at its rear end, forming a helical pair with the transmission screw 2134 installed therein. When the transmission screw 2134 rotates, the rotational motion of the driven bevel gear 2133 is converted into the horizontal linear motion of the transmission screw 2134 (i.e., rotational motion is converted into linear motion).

[0055] Please refer to Figure 4The power unit 22 includes: a power structure main body 221, a hoist 222 mounted on the power structure main body 221, a support leg drive motor 223, a limit switch 224, and a control box 225. When the truss 1 is hoisted to the working surface, the limit switch 224 is triggered. The control box 225 receives a signal from the limit switch 224 (at this time, the signal inside the control box 225 is cut off) to control the working state of the hoist 222 and the support leg drive motor 223 (at this time, the hoist 222 stops hoisting, so that the truss 1 is held on the current working surface, and the support leg drive motor 223 is in the working state). As can be seen from the above, the hoist 222 is used to lift the truss 1; the support leg drive motor 223 is used to provide opening and closing driving power for the support leg assembly 211 (horizontal support leg 2111 and vertical support leg 2112) installed on the truss 1. Therefore, due to the presence of the power unit 22, the tower crane's carrying capacity is not occupied at all, and hoisting operations can be carried out independently as needed.

[0056] Please refer to Figure 4 and Figure 5 The main body 221 of the power structure includes: a frame 2211, a support foot drive motor mounting base 2212 and a lifting lug 2213 disposed on the frame 2211, a sliding flange plate 2214 disposed on the side of the frame 2211, and a locking bolt 2215; wherein, the lifting lug 2213 is connected to the lifting hoist 222 (in other words, the lifting lug 2213 is used to hang the lifting hoist 222); after the sliding flange plate 2214 is inserted into the flange of the H-beam 3 on the corresponding side, the locking bolt 2215 fixes the sliding flange plate 2214 to the flange of the H-beam 3, thereby realizing the detachable installation of the power device 22 on the H-beam 3 on the corresponding side. Specifically, the grooved flange clamping plate 2214 includes an L-shaped bent clamping plate and a groove. The L-shaped bent clamping plate can be pulled out in the groove to adapt to its installation with H-shaped steel beams 3 of different flange widths.

[0057] In summary, the main function of the power unit is to assist in positioning, lift the truss 1, and provide power for the movement of the support legs (i.e., the horizontal support legs 2111 and the vertical support legs 2112 in the support leg assembly 211).

[0058] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments.

[0059] Accordingly, this embodiment also provides an application method for truss support equipment used to support steel structure floor slabs. See below for reference. Figures 1 to 16 This embodiment describes in detail the application method of the truss support equipment used to support steel structure floor slabs.

[0060] First, perform step S1, and adjust the two support components 21 in the two support power components 2 according to the cross-sectional dimensions of the H-shaped steel beam 3 at the construction site; specifically, adjust the length of the adjustable connecting rod accordingly.

[0061] Next, step S2 is performed, in which the two power units in the two supporting power components 2 are respectively installed and fixed on two adjacent H-shaped steel beams 3;

[0062] Next, please refer to Figure 14 Step S3 is executed, in which the two support components 21 are hoisted and fixed to the working surface based on the two power devices respectively;

[0063] Next, please refer to Figure 15 and Figure 16 In step S4, two support components 21 are connected and installed on both sides of a truss 1. With the cooperation of the two support components 21 and the corresponding H-beams 3, the truss 1 is supported and fixed between the two H-beams 3 to support the steel structure floor slab. The process of supporting and fixing the truss 1 between the two H-beams 3 with the cooperation of the two support components 21 and the corresponding H-beams 3 includes the following steps:

[0064] Driven by two motors from two power units, the horizontal support leg 2111 and the vertical support leg 2112 of the two support components 21 extend sequentially, respectively supporting the web and flange of the corresponding H-beam 3, thus fixing the truss 1 between the two H-beams 3. Specifically, after the horizontal support leg 2111 extends first and supports the web of the H-beam 3, due to the horizontal resistance, the force is released in the direction of less resistance, thereby driving the vertical support leg 2112 to extend until it abuts against the flange of the H-beam 3. This completes the installation of the support component 21. During construction, workers only need to work on the flange surface of the H-beam 3; workers only need to complete one action to complete installation or removal, reducing construction safety risks.

[0065] Next, step S5 is performed to remove the two power units fixed to the two H-shaped steel beams 3; specifically, the power units are removed by loosening the locking bolts 2215 of the main body of the power structure 221.

[0066] Next, step S6 is performed, where profiled steel sheets are laid on the fixed truss 1.

[0067] In summary, the truss support equipment and its application method for supporting steel structure floor slabs provided by this invention are designed to include: a truss and two support power components, which are detachably installed on two adjacent H-beams. Each support power component includes: a power unit and a support component hoisted onto the power unit, which is detachably installed on an H-beam. After the support component is hoisted to the working surface under the drive of the power unit, it is connected and installed with the truss. With the cooperation of the support component and the corresponding H-beam, the truss is fixed between the two H-beams to support the steel structure floor slab. The entire support and fixing process for the steel structure floor slab is based on the automatic completion of the work surface positioning and support construction by the power unit and support components. The entire process does not require tower crane hoisting, the installation process of the support equipment is simple, and it saves manpower and resources. At the same time, the truss support equipment can be automatically installed and disassembled as needed, which is simple and efficient to operate and reduces construction safety risks.

[0068] On the other hand, the power unit is designed with a pull-out chute structure, namely a chute-type flange clamping structure, to accommodate the installation of steel beams with different flange widths. At the same time, the opening range of the two vertical support legs can be adjusted by adjusting the length of the adjusting link to accommodate steel beams with different cross-sectional dimensions. These two adjustable designs greatly broaden the application range of the support equipment.

[0069] On the other hand, the horizontal and vertical supports of the support assembly adopt a less-than-freedom linkage design. By setting the linkage transmission angle, it is ensured that during the installation of the truss support equipment, the horizontal support extends first, abutting against the web of the H-beam, and then the vertical support extends until it is firmly against the flange of the H-beam. During disassembly, the horizontal and vertical supports move in the reverse order. Based on this design, on the one hand, it can ensure that one power source can drive the orderly movement of both supports, reducing the introduction of redundant power components, lowering manufacturing costs, and facilitating production, assembly, and maintenance. At the same time, the method of extending the horizontal supports first and then retracting the vertical supports first and then retracting them can effectively avoid the flanges, preventing the supports from colliding with the flanges of the H-beam during installation or disassembly, thus improving construction safety.

[0070] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
