Description

Technical Field

[0001] The present invention relates to the technical field of construction tools and methods for building construction projects, and particularly relates to a steel formwork trolley with a quick disassembly system suitable for pipe galleries and a construction method thereof. Background Art

[0002] The traditional steel formwork trolley is a new formwork support system for cast-in-place comprehensive pipe galleries. Different from wooden formwork, the traditional steel formwork trolley converts the steel pipe support frame of the conventional formwork system into an integral trolley gantry and uses screw jacks for top support reinforcement. Large steel formworks are suspended on the trolley gantry, and a hydraulic system is equipped. Through the telescopic movement of the hydraulic cylinders of the hydraulic system, the formwork can be assembled and disassembled integrally.

[0003] The advantages of the traditional steel formwork trolley compared with wooden formwork are as follows:

[0004] (1) It is equipped with a traveling system. In the formwork disassembled state, the integral movement of the steel formwork trolley can be realized by using the traveling system.

[0005] (2) It solves the disadvantages of the conventional formwork system, such as being difficult to transport and having low material strength.

[0006] The disadvantages of the traditional steel formwork trolley compared with wooden formwork are as follows:

[0007] When the traditional steel formwork trolley is used for construction in a sequential flow manner, since the formwork of the top plate cannot be disassembled until the concrete strength of the top plate reaches the design strength, when using the traditional steel formwork trolley, the waiting time for the concrete strength of the top plate greatly reduces the construction efficiency. While for wooden formwork, due to its low cost, the construction efficiency can often be improved by simultaneously investing in multiple sets of formwork.

[0008] Therefore, it is necessary to research a new formwork system that can not only retain the advantages of the traditional steel formwork trolley but also solve its disadvantages, which has become an urgent problem to be solved. Summary of the Invention

[0009] In order to solve one or more technical problems in the prior art, the purpose of the present invention is to provide a steel formwork trolley with a quick disassembly system suitable for pipe galleries and a construction method thereof. Improvements have been made at the connection between the top plate formwork and the side wall formwork, enabling the connection and separation of the side wall formwork and the top plate formwork to be freely realized. Thus, while retaining the advantages of the traditional steel formwork trolley, the disadvantage of its low efficiency is solved.

[0010] The object of the present invention is to provide a steel formwork trolley applicable to pipe galleries with a quick disassembly system, which is characterized in that it includes: a side wall formwork system (B, I, J) and a roof formwork system (A, C, D, E, F, G, H, K). The side wall formwork system is composed of a first side wall formwork system (B), a second side wall formwork system (J), a side wall formwork traveling system (I), a hydraulic system and a connecting device. The roof formwork system is composed of a roof formwork system, a telescopic device (F) for the roof formwork traveling wheels, a rotating device (G) for the roof formwork traveling wheels, a support system, a roof formwork traveling system, a lateral movement device (H) for the roof formwork traveling wheels and a contraction system. The side wall formwork and the roof formwork are respectively provided with traveling systems. In the formwork removal state, after the side wall formwork and the roof formwork are separated, the separate displacement of the side wall formwork and the roof formwork can be realized. The support system and the roof formwork traveling system respectively bear the load of the roof formwork when the roof formwork is in the working or non-working state, that is, when the roof formwork is in the working state, the support system bears the self-weight of the roof formwork and the construction load. When the roof formwork is in the formwork removal state, by retracting the hydraulic rods on the support system, the roof formwork system is stressed by the traveling system to realize the movement of the roof formwork. The contraction system is composed of hydraulic rods. The telescopic device (F) for the roof formwork traveling wheels is connected to the rotating device (G) for the roof formwork traveling wheels. The hydraulic rods are placed at the center of the rotating disc of the rotating device (G) for the roof formwork traveling wheels, and then through the rotation of the rotating device (G) for the roof formwork traveling wheels, the area occupied by the traveling wheels in the longitudinal section of the pipe gallery is reduced, and the lateral movement device (H) for the roof formwork traveling wheels moves to one side of the pipe gallery side wall to create enough moving space for the next set of roof formwork. The moving track of the lateral movement device (G) for the roof formwork traveling wheels is located inside the roof of the pipe gallery.

[0011] According to another aspect of the present invention, the roof formwork system is composed of a first roof formwork system (A) and a second roof formwork system (K).

[0012] According to another aspect of the present invention, the support system is composed of a support rod member system (C).

[0013] According to another aspect of the present invention, the roof formwork traveling system is composed of a first roof formwork traveling system (D) and a second roof formwork traveling system (E).

[0014] According to another aspect of the present invention, the side wall formwork system and the roof formwork system are connected by a reinforcing member, and the reinforcing member is a bolt.

[0015] According to another aspect of the present invention, the roof formwork traveling system is hydraulically connected to the roof formwork. When the roof formwork traveling system is stressed, the overall height of the roof formwork can be lowered.

[0016] According to another aspect of the present invention, the top plate formwork system is further provided with a top plate rotating device and a top plate sliding track. The top plate formwork traveling system can be displaced along the direction of the vertical pipe gallery through the top plate sliding track in the non-working state, and the support member (C) can be contracted.

[0017] According to another aspect of the present invention, the two ends of the top plate formwork can be folded through a hinge device.

[0018] According to another aspect of the present invention, it includes two sets of top plate formwork systems cooperating with one set of side wall formwork system. The top plate formwork system located in the first cabin directly passes through the steel formwork trolley of the quick-release system of the second cabin as a whole through the folding of the top plate formwork system, the displacement of the support system and the traveling system, and moves to the next working cabin.

[0019] The object of the present invention also lies in providing a construction method for a steel formwork trolley with a quick-release system applicable to a pipe gallery, including:

[0020] I. Construction of the side wall and top plate of the first cabin of the utility tunnel:

[0021] 1) Measuring and positioning, and placing the steel formwork trolley with a quick-release system at a fixed position;

[0022] 2) Using a hydraulic device to retract the traveling systems of the side wall formwork system and the top plate formwork system to make them in a non-working state;

[0023] 3) Fixing the side wall formwork system by connecting with a pull rod to the external formwork; or fixing the side wall formwork system through a connecting device in the case of no external formwork;

[0024] 4) Supporting the top plate formwork system through the support system (C), the support system (C) is composed of support members, and the support members are controlled by a multi-stage hydraulic system and can be multi-stage contracted and extended;

[0025] 5) Connecting the first top plate formwork system (A) and the first side wall formwork system (B) into a whole through the connecting and reinforcing members between the top plate formwork and the side wall formwork, and filling the gap between the two with a double-sided adhesive material;

[0026] 6) Retracting the top plate formwork traveling system through the top plate formwork traveling wheel telescopic device (F), and constructing the track at the folding part of the top plate formwork by a later installation method to avoid the track in this section affecting the folding of the top plate formwork;

[0027] 7) Since there is a hinge device on the top plate formwork as the second top plate formwork system (K), a double-sided adhesive material is used for filling the joint;

[0028] 8) After the side wall formwork and the top plate formwork are debugged, the top plate steel bar construction is carried out;

[0029] 9) Pour concrete into the side wall formwork and the top slab formwork;

[0030] II. Construction of the side wall and top slab of the second compartment of the utility tunnel:

[0031] 1) Remove the connection reinforcement between the side wall formwork and the first set of top slab formwork, separate the side wall formwork from the top slab formwork, and at the same time remove the formwork of the side wall formwork so that the side wall formwork system is supported by the walking system;

[0032] 2) Start the side wall formwork walking system (I) through the hydraulic device and move the side wall formwork to the working face of the second compartment;

[0033] 3) Use the second set of top slab formwork system equipped to cooperate with the side wall formwork system for construction, and the construction process is the same as that of the first set of top slab formwork;

[0034] III. Construction of the side wall and top slab of the third compartment of the utility tunnel

[0035] 1) Ideally, the side wall formwork system of the second compartment and the top slab formwork system of the first compartment are removed simultaneously for the construction of the third compartment of the utility tunnel;

[0036] 2) The method of moving the side wall formwork system of the second compartment to the third compartment is the same as the method of moving it to the second compartment;

[0037] 3) When the first compartment top slab formwork can be removed, the walking system returns to the center of the walking wheel track through the top slab formwork transverse movement device (H), then rotates the walking wheel to directly above the track through the top slab formwork rotation device (G), and lowers the walking wheel to contact the track through the top slab formwork walking wheel telescopic device (F). At this time, the walking wheel is stressed, and the force on the top slab formwork changes from the support system to the walking system;

[0038] 4) The support system (C) of the top slab formwork is contracted through the hydraulic system. After multi-stage contraction, the space occupied by the support rod (C) is reduced, facilitating the folding of the top slab formwork;

[0039] 5) Remove the connection reinforcement between the second set of top slab formwork and the side wall formwork, and separate the top slab formwork from the side wall formwork;

[0041] 7) Remove the track that affects the folding of the top slab formwork, that is, the installed track, which belongs to the top slab formwork walking wheel transverse movement device (G);

[0042] 8) Open the hinge device (K) on the top plate formwork so that the two sections of the top plate formwork fold, thereby reducing the width of the top plate formwork to ensure that it can pass between the second cabin support systems. At this time, the top plate formwork support member (C) retracts along with the top plate formwork;

[0043] 9) Driven by the traveling system, the first cabin top plate formwork quickly passes through between the second cabin top plate formwork support members and moves to the next working cabin, realizing the quick-disassembly system of the steel formwork trolley.

[0044] Compared with the prior art, the present invention has one or more of the following technical effects:

[0045] The steel formwork trolley and construction method applicable to the pipe gallery with a quick-disassembly system have been improved at the connection between the top plate formwork and the side wall formwork, and the connection and separation of the side wall formwork and the top plate formwork can be freely realized. Thus, while retaining the advantages of the traditional steel formwork trolley, the disadvantage of its low efficiency is solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Now, various embodiments will be described in detail, and one or more examples of these embodiments are respectively shown in the drawings. Each example is provided by way of explanation and not by way of limitation. For example, features shown or described as part of one embodiment can be used in or combined with any other embodiment to yield yet another embodiment. The present invention is intended to embrace such modifications and variations.

[0052] In the following description of the drawings, the same reference numerals indicate the same or similar components. Generally, only the differences of individual embodiments will be described. Unless otherwise clearly specified, the description of a part or aspect of one embodiment can also be applied to the corresponding part or aspect of another embodiment.

[0053] As Figures 1 to 4 shown, the steel formwork trolley applicable to the pipe gallery with a quick-release system in this embodiment is characterized by including: side wall formwork systems B, I, J and roof formwork systems A, C, D, E, F, G, H, K. The side wall formwork system is composed of a first side wall formwork system B, a second side wall formwork system J, a side wall formwork traveling system I, a hydraulic system and a connecting device; the roof formwork system is composed of a roof formwork system, a telescopic device F for roof formwork traveling wheels, a rotating device G for roof formwork traveling wheels, a support system, a roof formwork traveling system, a lateral movement device H for roof formwork traveling wheels and a contraction system. The side wall formwork and the roof formwork are respectively provided with traveling systems. In the formwork removal state, after the side wall formwork and the roof formwork are separated, the separate displacement of the side wall formwork and the roof formwork can be realized; the support system and the roof formwork traveling system respectively bear the load of the roof formwork when the roof formwork is in the working or non-working state, that is, when the roof formwork is in the working state, the support system bears the self-weight of the roof formwork and the construction load; when the roof formwork is in the formwork removal state, by retracting the hydraulic rods on the support system, the roof formwork system is stressed by the traveling system to realize the movement of the roof formwork; the contraction system is composed of hydraulic rods. The telescopic device F for roof formwork traveling wheels is connected to the rotating device G for roof formwork traveling wheels. The hydraulic rods are placed at the center of the rotating disc of the rotating device G for roof formwork traveling wheels, and then through the rotation of the rotating device G for roof formwork traveling wheels, the area occupied by the traveling wheels in the longitudinal section of the pipe gallery is reduced, and the lateral movement device H for roof formwork traveling wheels moves towards one side of the pipe gallery side wall to create enough movement space for the next set of roof formwork. The movement track of the lateral movement device G for roof formwork traveling wheels is located inside the roof of the pipe gallery.

[0054] In this embodiment, the roof formwork system is composed of a first roof formwork system A and a second roof formwork system K. The support system is composed of a support rod member system C. The roof formwork traveling system is composed of a first roof formwork traveling system D and a second roof formwork traveling system E. The side wall formwork system and the roof formwork system are connected by reinforcement members, and the reinforcement members are bolts. The roof formwork traveling system and the roof formwork are hydraulically connected. When the roof formwork traveling system is stressed, the overall height of the roof formwork can be lowered. The roof formwork system is also provided with a roof rotation device and a roof sliding track. The roof formwork traveling system can be displaced along the direction perpendicular to the pipe gallery through the roof sliding track in the non-working state, and the support rod C can be contracted. The specific working principle includes:

[0055] 1. In the top plate formwork system, the support member C is controlled by a multi-stage hydraulic system to contract. When the support system is stressed, the traveling system, i.e., the traveling wheels, is separated from the track through hydraulic lifting, and then the pulley is rotated through the rotating device. Relying on the transverse top plate sliding track device on the top plate formwork, the traveling wheels of the top plate formwork are moved to the side close to the side wall formwork. At this time, the support system is stressed, and the space between the support members C can be vacated.

[0056] 2. In the top plate formwork system, when the top plate formwork needs to be moved, it is moved to the center of the two tracks through the transverse top plate sliding track on the top plate formwork. The pulley is rotated by using the top plate formwork rotating device, and then the traveling wheels are lowered to contact the track through the top plate formwork traveling wheel telescopic device, realizing that the traveling system is stressed again.

[0057] 3. In the top plate formwork system, after the traveling system of the top plate formwork is stressed, the support member C is contracted through hydraulic control, and the top plate formwork descends. The top plate formwork can be folded through the hinge device, and the space occupied by the top plate formwork can be compressed, which is convenient for quickly passing through the second cabin.

[0058] The top plate formwork can be folded at both ends through the hinge device. After the first movement of the side wall formwork system, it is difficult to remove the top plate formwork system in a short time. Therefore, two sets of top plate formwork systems are put into use in cooperation with one set of side wall formwork system. The top plate formwork system located in the first cabin passes directly through the steel formwork trolley of the fast-disassembly system in the second cabin as a whole through the folding of the top plate formwork system, the displacement of the support system and the traveling system, and moves to the next working cabin.

[0059] The construction method of the steel formwork trolley with a fast-disassembly system applicable to the pipe gallery in this embodiment includes:

[0060] I. Construction of the side wall and top plate of the first cabin of the comprehensive pipe gallery:

[0061] 1. Measure and position, and place the steel formwork trolley with a fast-disassembly system at a fixed position;

[0063] 3. Fix the side wall formwork system by connecting with the tie rods of the external formwork; or fix the side wall formwork system through the connecting device in the absence of the external formwork;

[0064] 4. Support the top plate formwork system through the support system C. The support system C is composed of support members, and the support members are controlled by a multi-stage hydraulic system and can be multi-stage contracted and extended;

[0065] 5. Connect the first roof formwork system A and the first side wall formwork system B through the connecting and reinforcing members between the roof formwork and the side wall formwork to form an integral whole, and fill the gap between the two with double-sided adhesive material;

[0066] 6. Retract the roof formwork walking system through the roof formwork walking wheel telescopic device F, and construct the track at the folding part of the roof formwork by the later installation method to avoid the influence of this section of the track on the folding of the roof formwork;

[0067] 7. Since there is a hinge device on the roof formwork as the second roof formwork system K, double-sided adhesive material is used for caulking treatment;

[0068] 8. After the side wall formwork and the roof formwork are adjusted, carry out the construction of the roof reinforcement;

[0069] 9. Pour concrete into the side wall formwork and the roof formwork;

[0072] 2. Start the side wall formwork walking system I through the hydraulic device and move the side wall formwork to the working surface of the second compartment;

[0073] 3. Use the second set of roof formwork system equipped to cooperate with the side wall formwork system for construction, and the construction process is the same as that of the first set of roof formwork;

[0075] 1. Under ideal conditions, the side wall formwork system of the second compartment and the roof formwork system of the first compartment are removed at the same time for the construction of the third compartment of the utility tunnel;

[0076] 2. The method of moving the side wall formwork system of the second compartment to the third compartment is the same as the method of moving it to the second compartment;

[0077] 3. When the first compartment roof formwork can be removed, the walking system returns to the center of the walking wheel track through the roof formwork transverse movement device H, then rotates the walking wheel to directly above the track through the roof formwork rotation device G, and lowers the walking wheel to contact the track through the roof formwork walking wheel telescopic device F. At this time, the walking wheel is stressed, and the roof formwork changes from being stressed by the support system to being stressed by the walking system;

[0078] 4. The support system C of the roof formwork is contracted through the hydraulic system. After multi-stage contraction, the space occupied by the support rod C is reduced, which is convenient for the folding of the roof formwork;

[0079] 5. Remove the connecting and reinforcing members between the second set of top formwork and side formwork, and separate the top formwork from the side formwork;

[0080] 6. Utilize the telescopic device F of the top formwork traveling wheels to lower the height of the top formwork. At this time, the top formwork is removed from the formwork;

[0081] 7. Remove the track that affects the folding of the top formwork, that is, the installed track, which belongs to the transverse movement device G of the top formwork traveling wheels;

[0082] 8. Open the hinge device K on the top formwork to fold the two sections of the top formwork, thereby reducing the width of the top formwork to ensure that it can pass between the second cabin support systems. At this time, the top formwork support member C retracts with the top formwork;

[0083] 9. Drive through the traveling system to quickly pass the first cabin top formwork through the second cabin top formwork support members and move it to the next working cabin, realizing the quick disassembly system of the steel formwork trolley.

[0084] In this embodiment, the steel formwork trolley and construction method applicable to the pipe gallery with a quick disassembly system have been improved at the connection between the top formwork and the side formwork, and the connection and separation of the side formwork and the top formwork can be freely realized. Thus, while retaining the advantages of the traditional steel formwork trolley, the disadvantage of its low efficiency is solved.

[0085] Although the foregoing content is about the embodiments of the present invention, other and further embodiments of the present invention can be designed without departing from the basic scope of the present invention. The scope of the present invention is determined by the following claims.
