Description

Technical Field

[0001] The present invention belongs to the technical field of bridge engineering construction, and more specifically, relates to a support device and an installation method of a cantilever vertical elevator wall frame. Background Art

[0002] In the construction of high-speed railway bridges, continuous beams or continuous rigid frames are commonly used. Usually, as structures that cross roads or existing lines, their construction heights are generally low. In recent years, with the continuous development of high-speed railway technology and higher requirements for line layout flexibility, the construction height of continuous beams or continuous rigid frames in high-speed railway bridge construction has gradually increased. When the height exceeds 30m, especially when crossing river valleys, the height of the pier body together with the 0# block of the continuous rigid frame even exceeds 80m. It is necessary to use a construction elevator as a vertical transportation channel to transport personnel, construction materials and equipment to the bridge deck under construction. The traditional construction elevator wall frame system usually relies on bridge piers to provide support, but in some cases, the module of the elevator wall frame cannot fully match the construction height. For example, when the elevator needs to climb above the bridge beam surface, a cantilever condition may occur, that is, the elevator guide rail exceeds its fixed point by a distance, resulting in structural instability. The main door of the construction elevator cannot be opened normally due to insufficient climbing height. The construction personnel must climb over the top of the elevator car and use the height of the car to make up for the lack of climbing height before entering the construction area. This approach not only poses a risk to personnel safety management, but also causes mechanical equipment to be in unconventional working conditions for a long time, increasing maintenance workload and equipment safety risks. Summary of the invention

[0003] In view of the above defects or improvement needs of the prior art, the present invention provides a support device and a construction method for a cantilevered vertical elevator wall frame, by separately arranging a cantilevered vertical support frame on the bridge beam surface, the bottom of which is fixed with the anchor assembly, and the top is welded and installed with the connecting assembly, so as to provide a support point for the elevator wall frame above the beam surface, and connect the cantilevered vertical support frame and the elevator wall frame with a pin shaft, so as to achieve stable support for the elevator wall frame above the beam surface, thereby avoiding the occurrence of the cantilever working condition of the elevator guide rail when the elevator climbs to the bridge beam surface and the elevator main door is opened, thereby eliminating major equipment safety hazards.

[0004] To achieve the above-mentioned object, according to one aspect of the present invention, the present invention provides a support device for a cantilever vertical elevator wall frame, characterized in that it comprises: a cantilever vertical support frame on which the elevator wall frame is installed on the bridge beam surface, an anchoring assembly for fixing the cantilever vertical support frame to the beam surface, and a connecting assembly for connecting the elevator wall frame and the cantilever vertical support frame, wherein:

[0005] The cantilever vertical support frame has a triangular steel lattice structure, including vertical rods, horizontal rods, diagonal bracing rods and internal stiffening rods, each rod is welded together with ordinary steel, and the top rod reserves the welding position of the connecting assembly;

[0006] By separately setting the cantilever vertical support frame on the bridge beam surface, fixing its bottom with the anchor assembly, and welding the connecting assembly to the top rod, a support point is provided for the elevator wall frame above the beam surface, and the cantilever vertical support frame is connected to the elevator wall frame to achieve stable installation and stable support of the elevator wall frame.

[0007] Furthermore, the cantilever vertical support frame is arranged vertically to the elevator wall frame.

[0008] Furthermore, the anchoring assembly includes a precision-rolled threaded steel bar and a positioning steel plate, and one positioning steel plate and two precision-rolled threaded steel bars form a set of anchoring structures.

[0009] Furthermore, the fine-rolled threaded steel bars are pre-buried during the construction of the continuous rigid frame 0# block and can be reused, first used as the anchoring facility of the hanging basket and rear anchor during the suspended casting of the 1# block, and then used to fix the cantilever vertical support frame.

[0010] Furthermore, the connection assembly includes a long angle steel of the angle steel base welded to the top rod of the cantilever vertical support frame, and a short angle steel of the angle steel base installed on the long angle steel of the angle steel base and fixed by long and short angle steel fixing bolts.

[0011] Furthermore, the connection assembly also includes an angle steel base perforated ear plate welded on the center line of the short angle steel of the angle steel base to form a male and female joint with the elevator wall frame support angle ear plate.

[0012] Furthermore, the connection assembly also includes a pin installed in the reserved hole of the perforated ear plate of the angle steel base and the angle ear plate of the elevator wall support.

[0013] Furthermore, the cantilever vertical support frame is connected to the elevator wall frame via a pin to accommodate slight changes in the on-site connection angle.

[0014] According to another aspect of the present invention, the present invention provides a method for installing a support device of a cantilever vertical elevator wall-mounted frame, which is used to install the support device of the cantilever vertical elevator wall-mounted frame described above, and is characterized in that it includes the following steps:

[0015] S100: Construct the 0# block of the continuous rigid frame on the top of the bridge pier and embed the fine-rolled threaded steel bars during the construction process;

[0016] S200: After the construction of the continuous rigid frame 0# block is completed, the elevator guide rail is connected and the elevator bridge box climbs to close to the beam surface;

[0017] S300: The hanging basket is installed and anchored on the 0# block through the pre-buried fine-rolled threaded steel bars and nuts, and the construction of the 1# block begins. The staff temporarily enters the beam surface construction area by climbing on the top of the elevator car to perform auxiliary work;

[0020] S600: Extend the elevator guide rail again until it can support the elevator car to climb to the working height above the bridge deck, and install the elevator wall bracket on the cantilever vertical support frame through the connection assembly.

[0021] Furthermore, in step S300 and step S500, each finished rolled threaded steel bar has no less than 2 anchor nuts.

[0022] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0023] 1. The support device of the cantilever vertical elevator wall frame of the present invention separately sets a cantilever vertical support frame on the bridge beam surface and fixes it with an anchor assembly as a support point of the elevator wall frame, and is fixedly connected to the elevator wall frame through a connecting assembly, thereby solving the problem that the modulus of the traditional construction elevator wall frame does not match the construction height, resulting in a cantilever working condition when the construction elevator climbs to the highest floor, and the construction personnel need to climb over the roof of the elevator car to enter the construction area. The present invention avoids the cantilever working condition of the elevator guide rail when the elevator climbs to the bridge beam surface and the elevator front door is opened, thereby eliminating major equipment safety hazards, ensuring that the construction elevator is used in normal working conditions throughout the construction process, improving the construction personnel's work convenience and satisfaction with the working environment, and ultimately achieving the effect of obtaining inherent safety in current project management from the source of scheme design.

[0024] 2. The present invention firmly connects the elevator wall frame and the cantilever vertical support frame together through a connecting assembly including a long angle steel of an angle steel base, a short angle steel of an angle steel base, an angle steel base with perforated ear plates, bolts for fixing the long and short angle steels, and a pin shaft. The special pin shaft connection method can adapt to slight changes in the on-site connection angle, thereby improving the success rate of installation and the reliability of the system, and ensuring the safe operation of the construction elevator.

[0025] 3. The present invention uses an anchoring assembly including fine-rolled threaded steel bars and positioning steel plates to firmly fix the cantilever vertical support frame on the bridge beam surface, so that the cantilever vertical support frame can stably bear the horizontal load from the elevator wall frame and transfer it to the bridge beam body, ensuring the stability and safety of the overall structure. The fine-rolled threaded steel bars are first used as the fixing point of the rear anchor of the hanging basket, and then used to fix the cantilever vertical support frame, realizing the reuse of materials, reducing material consumption, and saving project costs.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

If the specific posture changes, the directional indication will also change accordingly. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0039] The embodiment of the present invention provides a support device for a cantilevered vertical elevator wall frame, including a cantilevered vertical support frame for the elevator wall frame installed on the bridge beam surface, an anchoring assembly for fixing the cantilevered vertical support frame to the beam surface, and a connecting assembly for connecting the elevator wall frame and the cantilevered vertical support frame. By separately arranging the cantilevered vertical support frame on the beam surface and fixing it with the anchoring assembly as a support point of the elevator wall frame, and fixing the connecting assembly with the elevator wall frame, when the elevator climbs to the bridge beam surface and the elevator main door is opened, the cantilevered working condition of the elevator guide rail is avoided, ensuring that the working condition of the construction elevator is normal during the entire construction process, and ensuring the safety of the construction workers.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] Example 1

[0042] See also Figures 1 to 3 The elevator wall frame 4 below the bridge deck is connected by embedded parts anchored on the continuous rigid frame pier 1. When the bridge deck is operated, the elevator continues to climb upward and a cantilever condition will occur. The device of the present invention adds an anchor point above the beam surface, which changes the working condition of the construction elevator at this time into a normal working condition, thereby ensuring construction safety.

[0043] Specifically, the cantilever vertical support frame 6 on which the elevator wall frame 4 relies is installed at the web on one side of the continuous rigid frame beam body 0# block 2, and a position for welding the connection assembly is reserved at its top. For the elevator on one side of the continuous rigid frame pier 1, after the wall frame structure 4 and the cantilever vertical support frame 5 are connected through the connection assembly, it can be ensured that the elevator car 5 climbs to the height of the beam surface of the bridge 0# block 2. When the front door of the elevator car 5 is opened, the elevator is in a normal working condition where the guide rail is not cantilevered. The anchoring device assembly of the cantilever vertical support frame 6 can fix the cantilever vertical support frame to bear the horizontal load generated by the elevator wall frame 4.

[0044] See also Figure 4-6The cantilever vertical support frame 6 is arranged vertically with the elevator wall frame 4. The main structure of the cantilever vertical support frame 6 is a triangular steel lattice structure, and the side elevation is a triangular structure. It is composed of vertical rods, horizontal rods, diagonal support rods and internal stiffening rods. Each rod (numbered 61 to 69) is made of ordinary steel and welded to each other. The selection of steel not only considers the strength and rigidity of the material, but also the cost-effectiveness and convenience of construction. The welded structure ensures the firmness of each node and enhances the integrity and durability of the entire support. The top rod 69 of the cantilever vertical support frame 6 reserves a welding position specifically for welding the connection assembly, thereby forming a firm connection with the elevator wall frame 4, ensuring that the connection between the elevator wall frame 4 and the support frame 6 is not only stable and reliable, but also able to withstand various loads and impacts that may occur during the construction process. The cantilever vertical support frame 6 is fixed by an anchor assembly pre-buried in the continuous rigid frame 0# block 2.

[0045] The anchoring assembly includes a fine-rolled threaded steel bar 7 and a positioning steel plate 8. One positioning steel plate 8 and two fine-rolled threaded steel bars 7 form a set of anchoring structures. The entire device has a total of four sets of the anchoring structures to ensure the stability of the cantilever vertical support frame 6 in all directions. The fine-rolled threaded steel bars 7 are all pre-buried during the construction of the continuous rigid frame 0# block 2. This pre-buried method not only ensures the close combination of the fine-rolled threaded steel bars 7 and the concrete structure, but also provides additional gripping force, enhances the anchoring force, and the fine-rolled threaded steel bars 7 can be reused - when the 1# block is suspended, the fine-rolled threaded steel bars 7 are first used as a fixing facility for the rear anchor of the hanging basket to provide a stable support for the hanging basket. After the hanging basket task is completed, the fine-rolled threaded steel bars 7 can be converted into a fixing assembly for fixing the cantilever vertical support frame 6, realizing efficient use of materials. The positioning steel plate 8 is provided with holes matching the fine-rolled threaded steel bars 7. The holes ensure that the fine-rolled threaded steel bars 7 can accurately pass through the positioning steel plate 8 and be fixed with nuts, thereby ensuring the accuracy and reliability of the entire anchoring structure. The bottoms of the rods 61 and 62 of the cantilever vertical support frame 6 are welded to the middle of the positioning steel plate 8, thereby improving the overall stability of the structure.

[0046] In actual construction, the installation of the anchor assembly requires precise operation to ensure its function. First, the positioning steel plate 8 is installed at the predetermined position of the continuous rigid frame 0# block 2, and then the fine-rolled threaded steel bar 7 is fixed in place through the holes on the positioning steel plate 8. Next, the rods 61 and 62 of the cantilever vertical support 6 are welded to the positioning steel plate 8 to complete the installation of the anchor assembly.

[0047] Reference Figure 7, the connection assembly includes a long angle steel 9 of the angle steel base, a short angle steel 10 of the angle steel base, a perforated ear plate 11 of the angle steel base, bolts 13 for fixing the long and short angle steels, and a pin 14. The elevator wall frame 4 is connected to the cantilever vertical support frame 6 through the pin 14. Specifically, the connection seat used for the pin 14, i.e., the angle steel base, includes the long angle steel 9 of the angle steel base, the short angle steel 10 of the angle steel base, and the perforated ear plate 11 of the angle steel base. The long angle steel 9 of the angle steel base is first welded to the horizontal rod 69 at the top end of the cantilever vertical support frame 6. The two short angle steels 10 of the angle steel base are installed on the long angle steel 9 of the angle steel base, and the spacing corresponds to the two legs of the elevator wall frame 4. The long angle steel 9 of the angle steel base and the short angle steel 10 of the angle steel base are fixed by the bolts 13. The perforated ear plate 11 of the angle steel base is welded on the center line of the short angle steel 10 of the angle steel base, and forms a male and female joint with the angle ear plate 12 of the elevator wall frame. After the ear plates are plugged, the pin 14 is installed in the reserved holes of the perforated ear plate 11 of the angle steel base and the angle ear plate 12 of the elevator wall frame to complete the connection. These components work together to ensure that a strong and flexible connection system is formed between the elevator wall frame 4 and the cantilever vertical support frame 6. In particular, the design of the pin 14 allows a certain angle adjustment to adapt to the slight deviation that may exist on site, thereby improving the success rate of installation and the reliability of the system.

[0048] The device of the present invention adopts a special connecting component to ensure a stable and reliable connection between the elevator wall frame 4 and the cantilever vertical support frame 6, and utilizes the stability of the triangular structure of the cantilever vertical support frame 6 to disperse and bear the load from the elevator wall frame 4, and transfers the load to the continuous rigid frame beam through the anchoring component, thereby ensuring the stability and safety of the overall structure.

[0049] Example 2

[0050] An embodiment of the present invention provides a method for installing a support device of a cantilever vertical elevator wall frame, comprising the following steps:

[0051] S100: Construction of the 0# block 2 of the continuous rigid frame on the top of the bridge pier, and pre-embedded fine-rolled threaded steel bars 7 during the construction of 0# block 2; these steel bars are not only used to fix the future cantilever vertical support frame 6, but also can be used as the fixing point of the rear anchor of the hanging basket during the 1# block hanging pouring in the early stage. The work of pre-embedded steel bars requires precise positioning to ensure the stability and safety of the subsequent structure.

[0052] S200: After the construction of the continuous rigid frame 0# block 2 is completed, the elevator guide rail 3 is connected, and the verticality and flatness of the guide rail are checked to ensure that they meet the requirements, and the elevator bridge box climbs to close to the beam surface. At this time, the elevator bridge box 5 is located below the beam surface.

[0053] S300: The hanging basket is installed and anchored on the 0# block 2 through the pre-buried fine-rolled threaded steel bars 7 and nuts, and the construction of the 1# block is started. Each fine-rolled threaded steel bar is anchored with no less than 2 nuts to ensure the stability of the hanging basket. Since the elevator bridge box 5 is located below the beam surface at this time, the staff temporarily enters the beam surface construction area by climbing the top surface of the elevator car 5 to perform auxiliary operations. During this process, strict safety protection measures must be taken, such as setting up temporary railings, wearing safety belts, etc., to ensure the safety of the staff.

[0054] S400: With the support of the hanging basket, the concrete pouring and other related processes of block 1# are completed. When block 1# reaches sufficient strength, the hanging basket of the anchoring facilities is removed and moved forward to restore the original state of the fine-rolled threaded steel bars 7, in preparation for the installation of the cantilever vertical support frame 6.

[0055] S500: The welded cantilever vertical support frame 6 is firmly fixed to the pre-buried fine-rolled threaded steel bar 7 of the original hanging basket rear anchor device through the positioning steel plate and nut. The technical specifications must be strictly followed during the installation process to ensure the stability of the structure. Four groups of four anchor structures are used, with a total of four positioning steel plates 8 and eight fine-rolled threaded steel bars 7. When installing the cantilever vertical support frame 6, the automated welding technology is used to improve the welding efficiency and quality and ensure the firmness and reliability of the welding points.

[0056] S600: The elevator guide rail 3 is extended again until it can support the elevator car 5 to climb to the working height above the bridge deck, and the elevator wall frame 4, i.e., the highest floor elevator wall frame, is installed on the cantilever vertical support frame 6 through the connecting assembly.

[0057] Through the steps of the above embodiment, the elevator is completely converted to a normal working state without a cantilever, and the staff can directly enter the beam surface construction area through the main door of the elevator cage 5, thereby solving the difficulties and pain points of climbing over the car roof during the use of the construction elevator, improving work efficiency and safety, and achieving the management goal of obtaining inherent safety from the source of scheme design in the current project management.

[0058] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
