Description

Technical Field

[0001] The utility model relates to the field of curtain wall construction auxiliary equipment, and particularly relates to a sliding device for steel structural members. Background Art

[0002] In the current construction industry, the design and implementation of large-span structures face many challenges, especially the increasing requirements for cantilever structures and curtain wall construction technologies. Traditional construction methods usually rely on the steel pipe scaffolding system built along the full height of the building as a support platform. However, this approach has significant limitations and deficiencies.

[0003] Firstly, from the perspective of resource consumption, the use of traditional steel pipe scaffolding is huge, requiring a large amount of steel pipe materials, which causes a considerable burden on the economic cost. With the fluctuation of steel prices and the increasing requirements for sustainable development, this resource-intensive construction mode is increasingly questioned.

[0004] Secondly, the installation efficiency issue cannot be ignored. Building a large-scale steel pipe scaffolding is time-consuming and seriously affects the overall project construction progress. In the fast-paced modern construction field, time is cost, and any technological innovation that can shorten the construction period has extremely high value.

[0005] More critically, the defects in technical adaptability are gradually emerging. With the innovation of building design, giant cantilever prestressed concrete structures and complex curved curtain walls are frequently used in large-span structures. These elements put forward higher standards for the construction support system. Due to the limitations of the structural stiffness, flexibility and load-bearing capacity of traditional steel pipe scaffolding, it is difficult to accurately match the needs of these special structures, resulting in increased construction difficulty and even in some cases, the design intention cannot be achieved.

[0006] It can be seen that the existing construction technologies are unable to cope with the special design requirements in large-span structures, especially in terms of improving material utilization efficiency, accelerating construction speed and meeting the construction requirements of complex structures. Therefore, developing an integrated working platform for rapid installation technology and a sliding device that can adapt to the cantilever and curtain wall construction of complex large-span structures is meaningful for the installation construction of steel structural members.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Generally, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0029] Embodiment 1

[0030] As Figure 1 shown, a sliding device for steel structure members includes a sliding shoe 1 and a load-bearing track 2. A steel structure member 3 is carried on the sliding shoe 1; a reaction force assembly including a C-shaped steel plate 4 and a reaction force wedge 5 is lockably arranged on the load-bearing track 2. The reaction force wedge 5 is connected to the bottom of the steel structure member 3 through a telescopic driving member 6; when the reaction force assembly is locked on the load-bearing track 2, through the telescopic movement of the telescopic driving member 6, the sliding shoe 1 and the steel structure member 3 carried thereon slide along the load-bearing track 2.

[0031] Among them, the sliding shoe 1, as the base directly carrying the steel structure member 3, needs to be designed to ensure a firm connection with the steel structure member and reduce friction and damage during the sliding process. The sliding shoe 1 itself can be made of wear-resistant materials, and its shape and size are customized according to the bottom contour of the steel structure member 3 to ensure good fit and load-bearing capacity.

[0032] The C-shaped steel plate 4 and the reaction force wedge 5 are installed on the load-bearing track 2, mainly playing the role of fixing and transmitting force. They can be embedded in specific positions of the track to increase stability. Under the action of the telescopic driving member 6, a reverse force is generated to drive the sliding of the sliding shoe and the steel structure member. This design utilizes the mechanical principle to enhance the controllability and safety of the device.

[0033] In this embodiment, as Figure 2As shown in the figure, the load-bearing track 2 includes an upper wing plate 21, a brace plate 22, a lower wing plate, and a web plate 23. The upper wing plate 21 and the lower wing plate are connected by a plurality of brace plates 22, and the web plate 23 is arranged between adjacent brace plates 22; the lengths of the upper wing plate 21 and the lower wing plate are the full lengths of the load-bearing track 2. The upper wing plate 21 and the lower wing plate form the main frame of the load-bearing track, providing a horizontal support surface, and its full-length design ensures the continuity and overall rigidity of the track. The brace plates 22 connect the upper and lower wing plates, increasing the lateral strength and stability of the track, enabling the track to withstand huge vertical loads without deformation. The web plate 23 is arranged between adjacent brace plates, strengthening the longitudinal stiffness of the track and preventing the track from bending or twisting due to long-term stress or heavy-load movement.

[0034] Based on the structure of the load-bearing track 2, the reaction wedge 5 is placed on the upper surface of the upper wing plate 21. The cross-sectional shape of the reaction wedge 5 is a right trapezoid, and its long waist side is arranged on the side away from the steel structure member 3. The vertical short waist side is connected to the bottom of the steel structure member 3 through a telescopic driving member 6; the C-shaped steel plate 4 is snapped onto the upper wing plate 21 through its downward opening, and the long waist side of the right trapezoid cross-section of the reaction wedge 5 is wedged between the upper wing plate 21 and the closed mouth of the C-shaped steel plate 4; the cross-section of the C-shaped steel plate 4 can be seen in Figure 4 the schematic diagram.

[0035] When the reaction wedge 5 is designed to be pushed by the telescopic driving member 6, it can effectively convert the force into the horizontal moving power along the track, causing the sliding shoe 1 and the steel structure member 3 to slide under the reaction force, and at the same time using the self-locking effect of the inclined plane to increase stability. When the long waist side of the reaction wedge 5 is wedged into the gap formed between the upper wing plate 21 and the closed mouth of the C-shaped steel plate 4, the locking state of the reaction force assembly is further strengthened, ensuring stability and easy control during the sliding process. Through the cooperation of the reaction force assembly and the load-bearing track 2, it is ensured that even when moving super-large and overweight steel structure members, high control accuracy and reliability can be achieved, which is applicable to the installation and relocation tasks of heavy curtain wall steel structures in various complex environments. By setting multiple sets of sliding devices for the overall steel structure member with multiple bottom supports in one operation and configuring the corresponding load-bearing track 2, the efficiency of the sliding installation operation of the steel structure member can be effectively improved.

[0036] In this embodiment, the telescopic driving member 6 is a horizontally placed jack; the non-telescopic end of the horizontally placed jack is fixedly connected to the vertical short waist side of the right trapezoid cross-section of the reaction wedge 5 through bolts, and the telescopic end of the horizontally placed jack is detachably fixedly connected to the bottom of the steel structure member 3.

[0037] Embodiment 2

[0038] Based on Embodiment 1, this embodiment introduces the structural design of the sliding shoe 1 in the sliding device. As Figure 3As shown in the figure, the sliding shoe 1 includes an upper sliding plate 11, and a left side plate and a right side plate disposed below the upper sliding plate; between the left side plate and the right side plate is the upper wing plate 21 of the load-bearing track 2, and the upper sliding plate 11 is disposed on the upper surface of the upper wing plate 21; the upper surface of the upper sliding plate 11 bears the steel structure member 3 and is detachably fixedly connected to the steel structure member 3. This design facilitates the loading and unloading of the steel structure 3 and the maintenance and replacement of the sliding shoe 1. Among them, the left side plate, the right side plate and the upper sliding plate 11 together constitute a guide rail structure for the sliding shoe 1 to slide along the load-bearing track 2, ensuring the stable guiding of the sliding shoe 1 on the load-bearing track 2.

[0039] The upper sliding plate 11 has an outer edge section in the width direction of the load-bearing track. Below the outer edge section, triangular reinforcing plates 12 are respectively disposed corresponding to the outer sides of the left side plate and the right side plate. The reinforcing plates 12 can enhance the lateral stability of the sliding shoe 1. Especially when bearing a heavier steel structure member, they can effectively resist lateral forces and prevent the sliding shoe from deforming.

[0040] Between the lower surface of the upper sliding plate 11 and the upper surface of the upper wing plate 21, a carbon tetrafluoride plate 13 is further disposed; the length of the carbon tetrafluoride plate 13 in the length direction of the load-bearing track 2 is greater than the length of the upper sliding plate 11 in the length direction of the load-bearing track 2. As a high-performance solid lubricant material, carbon tetrafluoride greatly reduces the friction coefficient between the sliding shoe 1 and the load-bearing track 2, making the sliding smoother. At the same time, it is wear-resistant and extends the service life of the entire device. Its ultra-long design in the track length direction ensures that even at the edge position of the sliding shoe 1, sufficient lubrication protection can be obtained, improving the uniformity and consistency of sliding.

[0041] Embodiment 3

[0042] On the basis of the above embodiments, this embodiment further improves the sliding device. As Figure 1 、 Figure 2 shown, support reaction frames 31 are respectively disposed at positions corresponding to both sides of the left side plate and the right side plate at the bottom of the steel structure member 3. Below the support reaction frames 31, vertically placed jacks are provided. The non-extendable ends of the vertically placed jacks are connected to the ground through pads, and the extendable ends of the vertically placed jacks are fixedly connected to the lower surfaces of the support reaction frames 31. The vertically placed jacks achieve the alternating conversion of the steel structure member 3 from the load-bearing track 2 to the ground support through telescopic operations, providing a technical basis for the continuous and stable progress of the sliding process.

[0043] Meanwhile, on one side surface of the C-shaped steel plate 4 facing the steel structure member 3, there is a release application end for releasing the reaction force assembly (not shown in the figure), and on the other side surface of the C-shaped steel plate 4 facing away from the steel structure member 3, there is a locking application end for locking the reaction force assembly (not shown in the figure). By applying force to the application ends on both sides of the C-shaped steel plate 4, it is convenient for on-site operators to lock and release the reaction force assembly in a relatively flexible and safe situation, and it also has the optimal force application points. If the structural functions of the C-shaped steel plate 4 of the reaction force assembly and the reaction force wedge 5 are swapped, that is, the C-shaped steel plate 4 is used to connect to the steel structure member 3 and the wedge locks on the other side, it will cause inconvenience in on-site use to a certain extent.

[0044] Through the above improved design, the sliding process of the steel structure member 3 along the load-bearing track 2 can achieve a step-by-step continuous effect. That is, when the vertically placed jack retracts, the steel structure member 3, the sliding shoe 1 come into contact with the load-bearing track 2 and are supported by it. At this time, the reaction force assembly is locked, and the steel structure member 3 and the sliding shoe 1 can be slid by the telescopic driving member 6. When the telescopic driving member 6 reaches the maximum elongation length, the vertically placed jack is telescoped, and the steel structure member 3 and the sliding shoe 1 are supported by the ground. At this time, the telescopic driving member 6 contracts, the reaction force assembly is released. After reaching the minimum contraction distance of the telescopic driving member 6, the vertically placed jack is retracted and the reaction force assembly is locked again to start the next round of sliding process. This phased operation method can ensure the continuity and accuracy of sliding, and is especially suitable for the curtain wall sliding installation scenarios with long distances or requiring precise alignment.
