Description

Technical Field

[0001] This utility model relates to the field of truss auxiliary installation technology, specifically a construction support device for large-span truss steel structures. Background Technology

[0002] A truss is a structure composed of members connected to each other at both ends by hinges. Trusses are planar or spatial structures generally composed of straight members with triangular units. Truss members mainly bear axial tensile or compressive forces, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight, and increase stiffness compared to solid beams.

[0003] Currently, during truss installation, cranes are mostly used to lift the central part of the truss. However, large-span trusses have a large mass and are suspended at both ends, resulting in poor stability during installation. The sides of the truss are prone to swaying, which increases the difficulty of installation for the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a construction support device for large-span truss steel structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A construction support device for a large-span truss steel structure includes a support plate, with a binding member connected to the bottom end of the support plate and a lifting member provided at the top end of the support plate. A crane lifts the support plate using the lifting member.

[0007] Extended plates are formed on both sides of the support plate, and side pressing components are provided at the bottom of the outer sides of the two extended plates.

[0008] The side-pressure assembly is equipped with a drive mechanism at the top. The drive mechanism drives the side-pressure assembly to move downward, thereby pressing down on both sides of the truss.

[0009] Preferably, the lifting component includes at least three pull ropes arranged in a circumferential array at the top of the support plate, and the ends of the pull ropes are fixed with lifting lugs.

[0010] Preferably, the side pressing component includes a horizontal plate, a stabilizing plate fixed to the bottom end of the horizontal plate, a vertical plate provided on the side of the stabilizing plate, a limiting groove formed on the side of the vertical plate, and a limiting block fixed on the side of the stabilizing plate, the limiting block being adapted to the limiting groove.

[0011] A pin is fixed at the top of the vertical plate, and the pin is movably connected to the horizontal plate. A spring connects the vertical plate and the horizontal plate.

[0012] A telescopic rod is fixed to the top of the horizontal plate, and the other end of the telescopic rod is fixed to the bottom of the extension plate.

[0013] The bottom of the vertical plate is movably connected to a pressure roller.

[0014] Preferably, at least one of the horizontal plates is fixed to the bottom end of a pressure sensor located directly above the vertical plate. The pressure sensor is used to monitor the pressure between the pressure roller and the truss. When the pressure reaches a threshold, the controller controls the dual-head motor to stop rotating.

[0015] Preferably, the driving mechanism includes a rotating rod, in which a threaded rod is movably screwed, and the bottom end of the threaded rod is fixed to the top end of the horizontal plate;

[0016] A dual-head motor is installed at the top of the support plate, and worm gears are connected to both output ends of the dual-head motor;

[0017] A worm gear is fixed on the shaft of the rotating rod, and the worm gear meshes with the worm.

[0018] Preferably, the binding component includes a strap with a hook fixed to one end and a buckle fixed to the bottom of the support plate, the buckle being compatible with the hook.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This new type of structure is equipped with a support plate, an extension plate, a side pressing component, and a drive mechanism. During installation, the top of the truss is tied with a binding member, and the top of both sides of the truss is squeezed by the side pressing component. At this time, the pressing rollers on both sides and the binding member form a triangular support for the truss, and the force is evenly distributed at both ends of the truss, which improves the stability of the truss positioning and reduces the installation difficulty.

[0021] In addition, a pressure sensor is installed to monitor and provide feedback on the extrusion pressure between the pressure roller and the truss in real time. When the pressure value reaches the threshold, the controller controls the dual-head motor to stop rotating, which further reduces the installation difficulty. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3 As shown, this utility model provides a technical solution: a construction support device for a large-span truss steel structure, including a support plate 1, a binding member 7 connected to the bottom end of the support plate 1, the binding member 7 including a binding strap, a hook fixed at the end of the binding strap, and a hook fixed at the bottom end of the support plate 1. In use, the binding strap is passed through the top of the truss, and after the binding strap is wound around, the hook is snapped onto the hook. A lifting member is provided at the top of the support plate 1. In this solution, in order to improve the stability of the support plate 1 during the lifting process, the lifting member includes at least three pull ropes 801. The pull ropes 801 are arranged in a circular array at the top of the support plate 1, and the top of the pull ropes 801 are gathered together. A lifting lug 802 is fixed at the end of the pull rope 801, and the hook of the crane is hung on the lifting lug 802, thereby enabling the support plate 1 and the truss on the binding member 7 to be lifted.

[0029] Extension plates 101 are formed on both sides of the support plate 1, and side pressing components 6 are provided at the bottom of the outer sides of both extension plates 101, such as... Figure 1 and Figure 3 As shown, the side-supporting component 6 includes a horizontal plate 601, a downwardly inclined stabilizing plate 603 fixed at the bottom end of the horizontal plate 601, and a vertically downward-pointing vertical plate 604 provided on the side of the stabilizing plate 603. A limiting groove is formed on the side of the vertical plate 604, and a limiting block is fixed on the side of the stabilizing plate 603. The limiting groove can be a Chinese character groove, a dovetail groove, or other irregular grooves. Correspondingly, the limiting block can be a Chinese character block, a dovetail block, or other irregular block. The limiting block is adapted to the limiting groove, thereby achieving stable support for the vertical plate 604.

[0030] At least one insert shaft 605 is fixed at the top of the vertical plate 604. The insert shaft 605 is movably inserted into the horizontal plate 601. At least one spring is connected between the vertical plate 604 and the horizontal plate 601, and the insert shaft 605 is located inside the spiral coil of the spring. A telescopic rod 602 is fixed at the top of the horizontal plate 601. The other end of the telescopic rod 602 is fixed to the bottom end of the extension plate 101. It is known that the telescopic rod 602 is composed of two tubes that are movably connected to each other. Its function is to ensure that the side pressing component 6 can move up and down.

[0031] A rubber-made pressure roller 607 is movably connected to the bottom of the vertical plate 604. In the working state, the pressure roller 607 presses against the top of both sides of the truss, thereby ensuring the stability of the truss with both ends suspended during installation.

[0032] In one specific embodiment of this solution, at least one horizontal plate 601 has a pressure sensor 606 fixed at its bottom end. The pressure sensor 606 is located directly above the vertical plate 604 and is electrically connected to the controller.

[0033] like Figure 1 As shown, a driving mechanism is provided on the top of the side pressing component 6. The driving mechanism drives the side pressing component 6 to move downward, thereby pressing down on both sides of the truss.

[0034] Specifically, the drive mechanism includes a rotating rod 201. A dual-head motor 203 is installed on the top of the support plate 1. Both output ends of the dual-head motor 203 are connected to worm gears 204. A worm wheel 205 is fixed on the rod body of the rotating rod 201 and meshes with the worm gear 204. A threaded rod 202 is movably screwed into the rotating rod 201. The bottom end of the threaded rod 202 is fixed to the top end of the horizontal plate 601. Since a telescopic rod 602 is installed on the top of the horizontal plate 601, the telescopic rod 602 interferes with the axial rotation of the horizontal plate 601. Thus, when the dual-head motor 203 drives the rotating rod 201 to rotate, the rotating rod 201 can drive the threaded rod 202 to move vertically along the direction of the rotating rod 201.

[0035] During installation, the top of the truss is secured with binding 7. The controller controls the dual-head motor 203 to rotate, and the worm gear 204 drives the worm wheel 205 to rotate. Since the telescopic rod 602 interferes with the axial rotation of the horizontal plate 601, when the worm wheel 205 drives the rotating rod 201 to rotate, the rotating rod 201 can drive the threaded rod 202 to move vertically along the direction of the rotating rod 201. The pressure roller 607 presses against the top of the side of the truss. At this time, the spring contracts, and the vertical plate 604 moves upward until the bottom of the vertical plate 604 presses against the pressure sensor 606. The pressure value of the pressure sensor 606 is transmitted to the controller in real time. When the pressure value reaches the threshold, the controller controls the dual-head motor 203 to stop rotating. At this time, the pressure rollers 607 on both sides and the binding 7 form a triangular support for the truss, and the force at both ends of the truss is even, which improves the stability of the truss positioning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
