Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a manufacturing mold for a diaphragm wall guide wall support structure. Background Technology

[0002] Diaphragm walls, also known as underground diaphragm walls, are widely used in deep foundation pit engineering. Guide walls are temporary structures installed before diaphragm wall construction. Their main functions include marking the excavation location of the diaphragm wall, controlling trenching accuracy, bearing the load of construction equipment, and preventing trench collapse, playing a fundamental role in ensuring the quality of diaphragm wall construction. Because guide wall construction often faces soft soil conditions such as miscellaneous fill, the guide wall itself lacks stability after the formwork is removed. It is prone to tilting and displacement due to external loads or soil deformation, which in turn affects the verticality and construction accuracy of the subsequent diaphragm wall trenching, and may even lead to damage to the guide wall requiring demolition and reconstruction. Therefore, supporting structures need to be installed between guide walls to quickly stabilize them.

[0003] Currently, the construction of the support structure between guide walls mostly adopts on-site formwork erection, concrete pouring, and formwork removal. The molds used are usually modular, and the on-site formwork erection and removal process is time-consuming and labor-intensive, resulting in low construction efficiency. It is difficult to meet the construction needs of rapid support after the guide wall formwork is removed, and the guide wall is prone to deformation due to untimely support.

[0004] Therefore, it is urgent to propose a manufacturing mold for the support structure between the diaphragm wall and the guide wall to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a manufacturing mold for a support structure between diaphragm walls and guide walls, which is beneficial to improving construction efficiency and meeting the demand for rapid support of guide walls.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a manufacturing mold for a diaphragm wall guide wall inter-support structure, comprising:

[0008] The support frame is installed on the ground outside two adjacent guide walls;

[0009] A supporting beam is connected to the bracket and erected on top of the reserved space between two adjacent guide walls;

[0010] The mold body is movably connected to the support beam below in a vertical direction. The mold body includes a first side wall, a bottom wall, and a second side wall connected in sequence. The projection shape of the mold body along its own length is U-shaped. The two ends of the mold body along its own length can abut against the inner walls of two adjacent guide walls. The top of the mold body is open. The mold body and the inner walls of the two adjacent guide walls form a casting space for the support structure.

[0011] In some embodiments, the mold body is connected to the support beam via a telescopic connector, and the telescopic connection can cause the mold body to move vertically up and down relative to the support beam.

[0012] In some embodiments, the retractable connector includes a first segment and a second segment, the first segment being connected between the support beam and the first sidewall, and the second segment being connected between the support beam and the second sidewall.

[0013] In some embodiments, two retractable connectors are provided, and the two retractable connectors are symmetrically connected to opposite ends of the mold body along its own length direction.

[0014] In some embodiments, the retractable connector is configured as a retractable chain.

[0015] In some embodiments, two supports are provided, one of which is provided on the ground outside each guide wall, and the support beam is erected between the two supports.

[0016] In some embodiments, the bracket is configured as a triangular bracket, the top of the bracket is provided with a mounting hole, and the support beam passes through the mounting hole.

[0017] In some embodiments, both the bracket and the supporting beam are made of metal.

[0018] In some embodiments, the first sidewall, the bottom wall, and the second sidewall of the mold body are all made of steel plates.

[0019] In some embodiments, the thickness of the steel plate is set to 3 mm.

[0020] The beneficial effects of this utility model are:

[0021] The manufacturing mold for the diaphragm wall guide wall support structure provided by this utility model has an integral mold body. Simply lowering it into place creates a casting space for the support structure between the inner walls of two adjacent guide walls. Simultaneously, demolding only requires lowering the mold body to detach it from the support structure, eliminating the cumbersome steps of traditional piecemeal molds for setting up and dismantling. This improves construction efficiency, meets the need for rapid support of guide walls, and effectively avoids guide wall deformation caused by untimely support. Furthermore, the manufacturing mold is reusable, which helps reduce construction costs. Attached Figure Description

[0038] like Figures 1-3 As shown, this embodiment provides a manufacturing mold for a diaphragm wall guide wall support structure, including a bracket 1, a support beam 2, and a mold body 3.

[0039] The bracket 1 is set on the ground outside the two adjacent guide walls.

[0040] The supporting beam 2 is connected to the bracket 1 and is erected on the top of the reserved space between two adjacent guide walls.

[0041] The mold body 3 is movably connected to the support beam 2 below in the vertical direction. The mold body 3 includes a first side wall 31, a bottom wall 32 and a second side wall 33 connected in sequence. The projection shape of the mold body 3 along its own length direction is U-shaped. The two ends of the mold body 3 along its own length direction can abut against the inner walls of two adjacent guide walls. The top of the mold body 3 is open. The mold body 3 and the inner walls of the two adjacent guide walls form a casting space for the support structure.

[0042] In practice, firstly, support brackets 1 are positioned and placed on the ground outside the two adjacent guide walls. Next, support beams 2 are installed on the support brackets 1. Then, the U-shaped mold body 3 is suspended vertically below the support beams 2. The position of the mold body 3 is adjusted so that it is at the pre-forming height of the support structure, and both ends of the mold body 3 abut against the inner walls of the two guide walls. At this point, the mold body 3 and the inner walls of the guide walls together enclose the casting space of the support structure. Then, concrete is poured into this casting space through the opening at the top of the mold body 3. After the concrete solidifies and reaches the design strength requirements, the mold body 3 is moved vertically downwards, detaching from the formed support structure, and demolding is quickly completed.

[0043] The manufacturing mold for the diaphragm wall guide wall support structure provided in this embodiment has an integral mold body 3. Simply lowering it into place creates a casting space for the support structure between the inner walls of two adjacent guide walls. Furthermore, demolding only requires lowering the mold body 3 to detach it from the support structure, eliminating the cumbersome steps of traditional piecemeal molds for setting up and dismantling. This improves construction efficiency, meets the need for rapid support of the guide walls, and effectively prevents guide wall deformation due to untimely support. Moreover, the manufacturing mold is reusable, which helps reduce construction costs.

[0044] like Figure 1 and Figure 2As shown, in some embodiments, the mold body 3 is connected to the support beam 2 via a telescopic connector 4, and the telescopic connector 4 can cause the mold body 3 to move up and down relative to the support beam 2 in the vertical direction.

[0045] By setting the retractable connector 4, the mold body 3 can be flexibly moved up and down in the vertical direction, easily completing the positioning and quick demolding of the mold body 3, making the operation simple and fast.

[0046] like Figure 2 As shown, in some embodiments, the telescopic connector 4 includes a first segment 41 and a second segment 42. The first segment 41 connects the support beam 2 and the first sidewall 31, and the second segment 42 connects the support beam 2 and the second sidewall 33. This arrangement helps to balance the forces on the mold body 3, preventing the mold body 3 from tilting or deforming, and also makes the up-and-down movement of the mold body 3 more stable.

[0047] like Figure 1 As shown, in some embodiments, there are two retractable connectors 4, which are symmetrically connected to opposite ends of the mold body 3 along its own length direction.

[0048] The two symmetrical telescopic connectors 4 can form balanced support from the opposite ends of the mold body 3 along the length direction, avoiding uneven force on both ends of the mold body 3 along the length direction, which can cause it to tilt or warp.

[0049] Optionally, the retractable connector 4 can be configured as a retractable chain. Retractable chains are simple in structure, low in cost, and readily available.

[0050] like Figure 1 As shown, in some embodiments, there are two supports 1, with one support 1 on the ground outside each guide wall, and the supporting beam 2 is erected between the two supports 1.

[0051] With this setup, the two supports 1 can provide symmetrical and stable support for the supporting beam 2, which helps to improve the overall stability of the manufacturing mold.

[0052] like Figure 3 As shown, in some embodiments, the bracket 1 is configured as a triangular bracket, and the top of the bracket 1 is provided with a mounting hole 11, through which the support beam 2 passes.

[0053] This design, utilizing the stability characteristics of a triangle, significantly enhances the overturning resistance of the support frame 1, thus providing a stable support foundation for the support beam 2 and the mold body 3. The mounting holes 11 at the top of the support frame 1 allow the support beam 2 to pass through, facilitating rapid positioning and installation of the support beam 2.

[0054] Optionally, both the bracket 1 and the supporting beam 2 are made of metal. Metal materials have high strength and rigidity, can effectively bear loads, and are not easily deformed.

[0055] For example, bracket 1 is made of iron, and support beam 2 is made of round steel.

[0056] In some embodiments, the first sidewall 31, bottom wall 32, and second sidewall 33 of the mold body 3 are all made of steel plates. The steel plate has high strength and can effectively resist the pressure during concrete pouring, preventing the mold body 3 from deforming; moreover, the surface of the steel plate is smooth and flat, with low adhesion to concrete, making it easier to detach from the formed support structure during demolding.

[0057] Optionally, the thickness of the steel plate is set to 3mm. A steel plate thickness of 3mm is moderate, providing sufficient rigidity to resist deformation while also having a moderate weight, making it easy to handle and move, thus balancing forming accuracy and construction convenience.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
