Description

Technical Field

[0001] This utility model relates to an installation component, specifically a mobile auxiliary installation component for erecting a support frame in the construction of cast-in-place box culverts. It is mainly used to assist in the installation and movement of the support frame during the construction of cast-in-place box culverts, and belongs to the field of auxiliary technology of construction supplies. Background Technology

[0002] Generally speaking, in the design and construction of highway culverts, based on the different peak ground acceleration, characteristic period of seismic response spectrum, and basic seismic intensity of the route area, culvert design is generally divided into precast slab type and cast-in-place monolithic type.

[0003] Traditional cast-in-place monolithic culvert construction requires dividing the culvert body into sections, and then carrying out scaffolding installation, formwork installation, rebar installation, concrete pouring, and scaffolding dismantling section by section. The process is complex and repetitive, especially the scaffolding installation and dismantling, which require significant manual labor. This is particularly problematic for cast-in-place box culverts with various span × height configurations, such as 4m × 3m, 4m × 2.5m, and 6m × 4.5m, where the maximum thickness of the box culvert top slab is 60cm, and the length varies from 42m to 72m. Settlement joints are installed every 4-6 meters, with a joint width of 2cm. In short, it is often very inconvenient.

[0004] As per design requirements, the cast-in-place box culvert is divided into 6-meter sections, with a settlement joint installed every 6 meters. To address the repetitive scaffolding installation and dismantling processes during construction and reduce labor requirements, the development of a safe, reliable, time-saving, and efficient improved telescopic concrete chute is crucial for solving the aforementioned technical problems. Summary of the Invention

[0005] To address the numerous defects and shortcomings in the aforementioned background technology, this utility model has made improvements and innovations, aiming to provide a simple, novel, and reasonable design that solves the repetitive work of installing and dismantling support frames during cast-in-place box culvert construction, reduces the number of manual laborers, and helps enterprises reduce costs and increase efficiency. Through the design of this utility model, channel steel is used to enhance the stability and safety of the frame during movement, and a specially designed walking mechanism for frame movement ensures the safety of the support frame during concrete pouring and frame movement.

[0006] To solve the above problems and achieve the above-mentioned objectives, this utility model provides a mobile auxiliary installation component for erecting a support frame for cast-in-place box culvert construction, achieved through the following design structure and technical solution:

[0007] As an improvement to the present invention, a mobile auxiliary installation component for erecting a support frame for cast-in-place box culvert construction includes a mobile auxiliary installation component body for installing scaffolding, the mobile auxiliary installation component body comprising:

[0008] The first support members, with the first support members arranged opposite to each other;

[0009] The second support members, there are several second support members, and several second support members are connected between two first support members at equal or unequal intervals to form the main body of the frame;

[0010] The traveling mechanism, which is symmetrically installed at the lower part of each second support member respectively for moving the main body of the frame;

[0011] The connecting card assembly is used to fix the lower part of the support frame above the main body of the frame to realize the installation and support of the support frame.

[0012] As an improvement of the above-mentioned utility model, the ends of each second support member are detachably connected to the corresponding first support member through a locking assembly.

[0013] As a further improvement of the above-mentioned utility model, two first support members are arranged above each second support member.

[0014] As a further improvement of the above-mentioned utility model, the cross-section of the first support member is in a "C" - shaped structure, and the top surface of the first support member is penetrated with first support member connection holes and first connection buckle holes at equal or unequal intervals.

[0015] As a further improvement of the above-mentioned utility model, the cross-section of the second support member is in a "C" - shaped structure, and the top surface of the second support member is penetrated with second support member connection holes and second connection buckle holes at equal or unequal intervals.

[0016] As a further improvement of the above-mentioned utility model, the traveling mechanism includes a mounting seat and moving wheels rotatably connected below the mounting seat, and the upper part of the mounting seat is detachably installed at the lower part of each second support member.

[0017] As a further improvement of the above-mentioned utility model, the connecting card assembly includes a first connection buckle and a second connection buckle, and the first connection buckle and the second connection buckle are respectively detachably installed on the first connection buckle hole of the first support member and the second connection buckle hole of the second support member.

[0018] As a further improvement of the above-mentioned utility model, the first connection buckle and the second connection buckle have the same shape structure but different heights; both the first connection buckle and the second connection buckle are in a "J" - shaped structure.

[0019] As a further improvement of the above-mentioned utility model, the locking assembly includes a connecting bolt, a connecting nut and a support sleeve sleeved outside the connecting bolt.

[0020] As a further improvement of the present invention, the height of the support sleeve is the same as the internal height of the first support member, wherein the lower part of the support sleeve abuts against the top plate of the second support member, and the upper part abuts against the inner wall of the top plate of the first support member.

[0021] The working principle is as follows: Before use, the construction personnel only need to assemble the mobile auxiliary installation component for the construction support frame of the cast-in-place box culvert with the above-mentioned design structure as needed and keep it ready for use.

[0022] During assembly, the operator simply needs to arrange the two pre-prepared first support members opposite each other.

[0023] Then, according to construction needs, multiple second support members are equidistantly connected between two first support members to form the main frame; at the same time, the ends of each second support member are detachably connected to the corresponding first support member through locking components; two first support members are set above each second support member, and at the same time, first connecting buckles and second connecting buckles are detachably installed on the first connecting buckle holes of the first support member and the second connecting buckle holes of the second support member, respectively. The first connecting buckles and the second connecting buckles are used to install the crossbars at the bottom of the support frame.

[0024] Finally, the pre-prepared multiple walking mechanisms are symmetrically installed on the lower part of each second support member to move the frame body. This completes the assembly of this utility model, which can then be used.

[0025] In use, construction workers only need to fix the lower part of the pre-prepared support frame to the upper part of the frame body of this utility model through the existing steel pipe components to achieve the installation and support of the support frame.

[0026] The support frame for the cast-in-place box culvert construction uses φ48×3 coupler-type steel pipe scaffolding as the support frame for the roof slab construction. The horizontal and vertical members of the scaffolding are connected as a whole using steel pipe couplers. Simultaneously, each vertical member of the scaffolding has a pull-out adjustable support bracket installed at its top, and support components, either steel pipes or timber, are placed inside each adjustable support bracket to support the roof slab. The specific installation is carried out using standard installation methods according to construction requirements. During the construction process, the main joists use double φ48×3 steel pipes, and the formwork uses plastic steel formwork. The elevation of the roof slab is adjusted using the adjustable support brackets. Plastic steel formwork is used for the sidewall construction and is fixed using tie rods and steel pipe back braces. After the fixed and reliable installation is completed, the subsequent concrete pouring process can proceed.

[0027] As time goes by, when the concrete pouring is completed and the concrete has solidified to the point where it can be removed, the construction workers only need to remove each formwork. During the removal, the liftable support top installed inside the upper upright of the scaffold is lowered to a certain height, so that the top plate position is lowered to a suitable height.

[0028] Finally, the frame of this utility model is moved in the same direction by multiple construction workers, so that the entire support frame is moved to the next section to continue the support construction work. The above operation is repeated until all the box culvert cast-in-place construction is completed.

[0029] Once all the box culverts have been cast in place, the operators only need to remove the support frame from the installation components of this utility model, clean and repair each component of this utility model, and then transport this utility model and the support frame to the designated tool storage warehouse by manual labor or appropriate handling equipment for storage, so as to prepare for the next cycle of use.

[0030] The beneficial effects of this utility model compared with the prior art are:

This utility model has a simple structure and a novel and reasonable design, solving the problem of repetitive work in the installation and dismantling of support frames during the construction of cast-in-place box culverts, reducing the number of manual laborers, and saving costs and increasing efficiency for enterprises. Through the design of this utility model, channel steel is used to enhance the stability and safety of the frame when it is moved, and a special walking mechanism for the frame movement is designed to ensure the safety of the support frame during concrete pouring and frame movement.

[0032] 2. This utility model has a simple structure, novel design, easy operation, convenient handling, good integrity, and high stability. Compared with the traditional method of manually dismantling and reassembling the scaffolding after each section of construction is completed, this design structure can achieve high-efficiency construction and meet the needs of pouring, thereby minimizing the labor intensity of operators.

[0033] 3. This utility model is labor-saving, time-saving, easy to install, and can be reused, saving resources and costs. The installation components can be reused, reducing project costs.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] As per the instruction manual Figure 1 To the instruction manual Figure 16 The illustrated mobile auxiliary installation assembly for erecting a support frame in cast-in-place box culvert construction includes a mobile auxiliary installation assembly body for installing the scaffolding. The mobile auxiliary installation assembly body comprises:

[0066] The first support member 1 is arranged opposite to each other;

[0067] The second support member 2, and there are several second support members 2 which are connected between two first support members 1 at equal or unequal intervals to form a frame body;

[0069] The connecting card assembly 4, which is used for fixing the lower part of the support frame body 6 above the frame body to realize the installation and support of the support frame body 6.

[0070] Further, as Figures 13 to 16 shown, the ends of each second support member 2 are detachably connected to the corresponding first support member 1 through the locking assembly 5.

[0071] Specifically, as Figure 13 and Figure 14 shown, the two first support members 1 are arranged above each second support member 2.

[0072] Further, as Figures 14 to 16 shown, the cross-section of the first support member 1 is in a "C" shape structure, and the top surface of the first support member 1 is provided with first support member connection holes and first connection buckle holes at equal or unequal intervals through it.

[0073] Further, as Figures 14 to 16 shown, the cross-section of the second support member 2 is in a "C" shape structure, and the top surface of the second support member 2 is provided with second support member connection holes and second connection buckle holes at equal or unequal intervals through it.

[0074] Further, as Figures 14 to 16 shown, the traveling mechanism 3 includes a mounting seat and moving wheels rotatably connected below the mounting seat, and the upper part of the mounting seat is detachably installed at the lower part of each second support member 2.

[0075] Further, as Figure 13 shown, the connecting card assembly 4 includes a first connection buckle 41 and a second connection buckle 42, and the first connection buckle 41 and the second connection buckle 42 are respectively detachably installed on the first connection buckle hole of the first support member 1 and the second connection buckle hole of the second support member 2.

[0076] More specifically, as Figure 13 shown, the first connection buckle 41 and the second connection buckle 42 have the same shape structure and different heights; both the first connection buckle 41 and the second connection buckle 42 are in a "J" shape structure.

[0077] Further, as Figure 16 shown, the locking assembly 5 includes a connecting bolt 51, a connecting nut 52 and a support sleeve 53 sleeved outside the connecting bolt 51.

[0078] More specifically, such as Figure 16 As shown, the height of the support sleeve 53 is the same as the internal height of the first support member 1. The lower part of the support sleeve 53 is in contact with the top plate of the second support member 2, and the upper part is in contact with the inner wall of the top plate of the first support member 1.

[0079] In this utility model, after the support sleeve 53 is installed between the first support member 1 and the second support member 2, the bottom of the two side plates of the first support member 1 and the top plate of the second support member 2 are securely connected together by connecting bolts 51 and connecting nuts 52.

[0083] In summary, a more specific embodiment of this utility model is as follows:

[0084] Example 1

[0085] Before using the above-mentioned design structure, the pre-made installation components need to be transported to the designated construction location by appropriate handling equipment or directly by manual labor for installation as a backup.

[0086] During assembly, the operator simply needs to arrange the two pre-prepared first support members 1 opposite each other.

[0087] Then, according to construction needs, multiple second support members 2 are connected between two first support members 1 at equal or unequal intervals to form the main frame; at the same time, the ends of each second support member 2 are detachably connected to the corresponding first support member 1 through locking components 5; the two first support members 1 are set above each second support member 2, and at the same time, the first connecting buckle 41 and the second connecting buckle 42 are respectively detachably installed on the first connecting buckle hole of the first support member 1 and the second connecting buckle hole of the second support member 2. The first connecting buckle 41 and the second connecting buckle 42 are both used to install the crossbar at the bottom of the support frame 6.

[0088] Finally, the pre-prepared multiple walking mechanisms 3 are symmetrically installed on the lower part of each second support member 2 for moving the frame body. Thus, the assembly of this utility model is completed, and it can be used after assembly.

[0089] In use, construction workers only need to fix the lower part of the pre-prepared support frame 6 above the main frame of the design structure of this utility model to install and support the support frame 6.

[0090] The support frame 6 used for the cast-in-place construction of the box culvert employs φ48×3 coupler-type steel pipe scaffolding as the support frame for the roof slab construction. The horizontal and vertical members of the scaffolding are connected as a single unit using construction couplers. Simultaneously, each vertical member of the scaffolding has a pull-out adjustable support top bracket 61, and support components 62, made of steel pipes or timber, are placed within each adjustable support top bracket 61 to support the roof slab 10. The specific installation of the support frame 6 is carried out using conventional installation methods according to construction requirements. During the construction process, the main joists use double φ48×3 steel pipes, and the formwork uses plastic steel formwork. The elevation of the roof slab 10 is adjusted using the adjustable support top brackets 61. Plastic steel formwork is used for the sidewall construction and is fixed using tie rods and steel pipe back braces. After the fixed and reliable installation is completed, the subsequent concrete pouring process can proceed.

[0091] As time goes by, when the concrete pouring is completed and the concrete has solidified to the point where it can be removed, the construction workers only need to remove each formwork. During the removal, the liftable support 61 installed inside the upper upright of the scaffold is lowered to a certain height, so that the top plate 10 is lowered to a suitable height.

[0092] Finally, the frame of this utility model is moved in the same direction by multiple construction workers, and then moved to the next section along with the entire support frame 6 via the walking mechanism 3 to continue the support construction work. The above operation is repeated until all the box culvert cast-in-place construction is completed.

[0093] Once all the box culverts have been cast in place, the operators only need to remove the support frame 6 from the installation components of this utility model, clean and repair each component of this utility model, and then transport this utility model and the support frame 6 to the designated tool storage warehouse by manual labor or appropriate handling equipment for storage, so as to prepare for the next cycle of use.

[0094] In this embodiment 1, the movement is carried out manually. During the movement, according to Formula 1, μ is taken as 3%, and N = 5.8 + 6.6 + 6.6 × 2 = 38 kN.

[0095] F 摩擦力 =μN=0.03×38KN=1140N

[0096] Since an adult can normally generate 300N of thrust [7] Therefore, the movable cast-in-place support designed in this case only requires 4 to 5 adults to push it forward.

[0097] Example 2

[0098] This embodiment 2 is the same as embodiment 1, such as... Figures 2 to 5 As shown, the only difference is that when the concrete is poured and ready to be moved to the next section for construction, the operator only needs to use a pre-prepared electric hoist 7 to pull the structure. During this movement, if the supporting frame 6 is heavy, gripping points can be pre-embedded in the expansion joint or base plate in front of the supporting frame 6. The electric hoist 7 is then fixed at these gripping points, and a steel cable is used to connect the electric hoist 7 to the second support member 2 on the main frame. The electric hoist 7 can then be used to pull the frame forward to the predetermined position via the walking mechanism 3. In this solution, attention should be paid to the installation components; the steel cable between the main frame and the electric hoist 7 should form a triangular shape to avoid single-point pulling causing the main frame to deviate in the direction of movement.

[0099] Other uses are the same as in Example 1, and will not be repeated here.

[0100] Example 3

[0101] This embodiment 3 is the same as other embodiments, except that, as Figures 6 to 9As shown, when the scaffold is ready to be moved to the next section for construction after the second pour, if the scaffold is heavy, an electric telescopic device 8 can be used for movement. The electric telescopic device 8 is a high-thrust electric push rod. A post-pouring hole is set in the bottom plate at the rear of the scaffold, and a reaction point is placed in the hole. A pre-embedded positioning part 9, which is an I-beam, can be used. The I-beam profile is placed vertically as a reaction device, and the electric push rod is fixed to the reaction point. The push rod rests on the second support member 2 of the scaffold, and the second support member 2 can then be pushed forward. The push rod is generally one meter long, and when fully extended, the total length of the push rod is two meters. By adding an I-beam as a pad between the reaction I-beam and the push rod, the scaffold can be continuously pushed forward by the traveling mechanism 3. After the scaffold reaches the predetermined position, the post-pouring hole is sealed with the same grade of concrete. In this scheme, two electric push rods and a circuit synchronization controller should be used to avoid deviation of the scaffold's movement direction caused by single-point pushing.

[0102] Other uses are the same as in Example 1, and will not be repeated here.

[0103] Finally, it should be noted that the specific embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made to it.
