Abstract

This application relates to the field of coal mining technology and provides a flexible formwork for concrete pouring along goaf retention roadways. The formwork includes a first formwork, a second formwork, and a connecting structure. The connecting structure includes a mounting base, a locking block, and a first locking element. The mounting base is disposed on the first formwork, and the locking block is disposed on the second formwork. The mounting base has a slot into which the locking block can be inserted. The first locking element is disposed on the mounting base and used to fix the locking block in the slot. By setting up this connecting structure, when the first and second formworks are joined, the locking block enters the slot, and the first locking element fixes the locking block in the slot, thus securing the first and second formworks. When separating the first and second formworks, rotating the first locking element disengages it from the locking block, and pulling the second formwork removes the locking block from the slot, thus separating the first and second formworks. This allows for rapid assembly and disassembly of the first and second formworks, improving operational efficiency.

Description

Technical Field

[0001] This application relates to the field of coal mining technology, and more specifically, to a flexible formwork for concrete pouring along the goaf. Background Technology

[0002] Goaf retention is an important technology for achieving pillarless mining in coal mines. It effectively alleviates the tension between mining and excavation, improves coal recovery rate, and enables Y-shaped ventilation of the working face, solving the problem of excessive gas in the upper corner. It is widely used in coal mining. Flexible formwork concrete is widely used due to its advantages such as high strength of the cast body and simple process.

[0003] The prior art CN220226908U discloses a flexible formwork for concrete pouring along the goaf, including formwork one, formwork two, stabilizing mechanism and supporting mechanism. The stabilizing mechanism is used to fix formwork one and formwork two, and the supporting mechanism is used to further improve the stability of the connection between formwork one and formwork two.

[0004] However, the existing technology has a complex structure, which makes it troublesome to assemble and disassemble template one and template two, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this application is to provide a flexible formwork for concrete pouring along the goaf, which can quickly disassemble and assemble the first and second formwork, thereby improving work efficiency.

[0006] This application provides a flexible formwork for concrete pouring along a goaf-retention tunnel, employing the following technical solution:

[0007] A flexible formwork for casting concrete along a goaf, comprising a first formwork, a second formwork, and a connecting structure disposed between the first and second formworks. The connecting structure includes a mounting base, a locking block, and a first locking member. The mounting base is disposed on the first formwork, the locking block is disposed on the second formwork, the mounting base has a slot, the locking block can be inserted into the slot, and the first locking member is disposed on the mounting base and is used to fix the locking block in the slot.

[0008] Preferably, a second locking member is provided between the card block and the second template, the card block can rotate around the second locking member, and the second locking member is used to fix the card block on the second template.

[0009] Preferably, the card block is provided with mounting holes.

[0010] Preferably, both the first locking member and the second locking member are hand-tightening screws.

[0011] Preferably, the mounting hole is a threaded hole.

[0012] Preferably, both the first locking member and the second locking member are provided with anti-slip texture.

[0013] Preferably, both the card block and the card slot have a dovetail-shaped structure.

[0014] Preferably, the connection structure is provided in two sets.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This application, by setting a connection structure, allows the first template and the second template to be fixed in place when they are joined together. When the first template and the second template are joined together, the locking block enters the slot and is fixed in place by the first locking member. When the first template and the second template are separated, the first locking member is rotated to disengage from the locking block, and the second template is pulled to remove the locking block from the slot, thus separating the first template and the second template. This allows for quick assembly and disassembly of the first template and the second template, improving work efficiency. Attached Figure Description

[0029] Example

[0030] like Figure 1-4 As shown in the embodiment of this application, the flexible formwork for casting concrete along the goaf includes a first formwork 1, a second formwork 2, and a connecting structure 3 disposed between the first formwork 1 and the second formwork 2. The connecting structure 3 includes a mounting base 4, a locking block 5, and a first locking member 6. The mounting base 4 is disposed on the first formwork 1, and the locking block 5 is disposed on the second formwork 2. The mounting base 4 has a locking groove 7, into which the locking block 5 can be inserted. The first locking member 6 is disposed on the mounting base 4 and is used to fix the locking block 5 in the locking groove 7. Specifically, in practical applications, if multiple formworks are spliced ​​together, the connecting structure 3 is arranged between two adjacent formworks.

[0031] When the first template 1 and the second template 2 are joined, the locking block 5 enters the slot 7 and is fixed in the slot 7 by the first locking member 6, thus fixing the first template 1 and the second template 2. When separating the first template 1 and the second template 2, the first locking member 6 is rotated to disengage from the locking block 5, and the second template 2 is pulled to remove the locking block 5 from the slot 7, thus separating the first template 1 and the second template 2. This allows for quick assembly and disassembly of the first template 1 and the second template 2, improving work efficiency.

[0032] In this embodiment, a second locking member 8 is provided between the card block 5 and the second template 2. The card block 5 can rotate around the second locking member 8. The second locking member 8 is used to fix the card block 5 on the second template 2. In the non-use state, the card block 5 can be rotated so that the card block 5 enters the central groove of the second template 2, and then the second locking member 8 is used to fix the card block 5, thereby preventing the card block 5 from being exposed and improving the portability of the second template 2.

[0033] In this embodiment, the card block 5 is provided with a mounting hole 9. When the first locking member 6 fixes the card block 5 inside the card slot 7, the end of the first locking member 6 enters the mounting hole 9.

[0034] In this embodiment, both the first locking member 6 and the second locking member 8 are hand-tightening screws. Using hand-tightening screws as locking members can reduce the reliance on external tools and improve the ease of use.

[0035] In this embodiment, the mounting hole 9 is a threaded hole. The threaded hole can improve the stability of the connection between the first locking member 6 and the card block 5, and improve the stability of the connection structure 3 between the first template 1 and the second template 2.

[0036] In this embodiment, both the first locking member 6 and the second locking member 8 are provided with anti-slip textures. The anti-slip textures are used to increase friction, thereby facilitating the rotation of the first locking member 6 and the second locking member 8.

[0037] In this embodiment, both the card block 5 and the card slot 7 are dovetail-shaped structures. The dovetail-shaped card block 5 and the card slot 7 cooperate with each other to have self-locking properties, and become tighter under force, making the connection structure 3 between the first template 1 and the second template 2 more stable.

[0038] In this embodiment, two sets of connection structures 3 are provided. The arrangement of two sets of connection structures 3 can improve the stability of the connection between the first template 1 and the second template 2.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
