Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a shaft formwork. Background Art

[0002] During the casting construction of the shaft wall, a series of procedures are required, such as building formwork and pouring concrete. Especially for the construction of long-distance shaft walls, due to the long length of the wall, the construction workers cannot perform casting operations on the ground. Therefore, it is necessary to use a formwork that can be raised and lowered along the height direction of the wall to change the height of the working plane, so as to realize the segmented continuous casting of the wall.

[0003] In the formwork in the prior art, the working plane is supported by multiple lifting mechanisms arranged at intervals along the horizontal direction. Each lifting mechanism is composed of two sets of frames and a driving device that serve as guides for each other.

However, the above-mentioned formworks are all used for the construction of exterior walls of buildings. The formworks only need to be connected to the exterior wall on one side. In the shaft, the space is narrow and the inner wall is annular.

[0050] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0051] like Figure 1-Figure 6As shown, the utility model provides a shaft mold frame for driving a working plane to move along the extension direction of the shaft. The shaft mold frame is configured to support a working plane, and the working plane is arranged around the shaft. Usually, the shaft extends in the vertical direction, so the shaft mold frame is configured to drive the working plane to move in the vertical direction. The shaft mold frame includes a first sleeve 1, a second sleeve 2 and a driving assembly 3. Among them, the first sleeve 1 can move in the vertical direction relative to the inner wall 100 of the shaft, and can be locked to the inner wall 100. In the horizontal direction, the first sleeve 1 is connected between two opposite inner walls 100, and the second sleeve 2 can move in the vertical direction relative to the inner wall 100 of the shaft, and can be locked to the inner wall 100. A sleeve cavity is provided in the second sleeve 2, and an opening connected to the sleeve cavity is provided at the bottom end of the second sleeve 2. The first sleeve 1 can enter the sleeve cavity through the opening, and the driving assembly 3 is respectively connected to the first sleeve 1 and the second sleeve 2, and is configured to drive the first sleeve 1 and the second sleeve 2 to move closer to or away from each other in the vertical direction.

[0052] The working plane is erected on the shaft formwork to carry construction personnel and equipment. In the horizontal direction, the first frame 1 is erected between the two opposite inner walls 100 of the shaft to support the working plane arranged around the shaft. When the working plane needs to be lowered, the first frame 1 is first unlocked from the inner wall 100, and the first frame 1 is driven by the driving component 3 to be lowered downward in the vertical direction to a predetermined position, and the first frame 1 is locked to the inner wall 100 of the shaft. Then, the second frame 2 is unlocked from the inner wall 100 of the shaft, and the second frame 2 is driven by the driving component 3 to be lowered downward in the vertical direction to a predetermined position, and finally the second frame 2 is locked to the inner wall 100 of the shaft. The operation process has high stability, the overall structure of the device is simple, cost-saving, and not easy to damage.

[0053] It can be understood that when the working plane needs to be lifted, the second frame 2 is first unlocked from the inner wall 100, and the second frame 2 is driven to rise vertically to a predetermined position by the driving assembly 3, and the second frame 2 is locked to the inner wall 100 of the shaft, and then the first frame 1 is unlocked from the inner wall 100 of the shaft, and the first frame 1 is driven to rise vertically to a predetermined position by the driving assembly 3, and finally the first frame 1 is locked to the inner wall 100 of the shaft.

[0054] In this embodiment, the material of the first frame 1 and the second frame 2 is limited to channel steel or angle steel, and the first frame 1 and the second frame 2 are connected to the inner wall 100 by bolts, so it is necessary to reserve a plurality of groups of connection holes corresponding to the bolts on the inner wall 100 so that the first frame 1 and the second frame 2 can be locked or unlocked with the inner wall 100, and the spacing between two adjacent groups of connection holes is determined by the operational requirements and is not limited here.

[0055] Specifically, the first set frame 1 also includes a support frame 11, a first main frame 12 and a first limit frame 13. Among them, the support frame 11 is detachably connected between the opposite inner walls 100 in the horizontal direction; the first main frame 12 is connected to the top of the support frame 11; the first limit frame 13 is connected between the first main frame 12 and the inner wall 100, and the first limit frame 13 is configured to be detachably connected to the inner wall 100. With the above arrangement, the support frame 11 and the first limit frame 13 cooperate, so that the first set frame 1 can be locked to the inner wall 100 more stably.

[0056] More specifically, only one or two first limiting frames 13 may be provided, and the two first limiting frames 13 are arranged on both sides of the first main frame 12 in a horizontal direction and are connected to opposite inner walls 100, respectively, to improve the stability of the first set frame 1. In this embodiment, the first limiting frame 13 is an integral rectangular frame with diagonal braces arranged inside.

[0057] It is understandable that a bolt structure is provided on the first limiting frame 13 , and the bolt structure is provided on the contact surface between the first limiting frame 13 and the inner wall 100 , so that the first limiting frame 13 can be unlocked or locked to the inner wall 100 .

[0058] Specifically, the support frame 11 includes a bearing portion 111 and two connecting portions 112. The bearing portion 111 is configured to bear the first main frame 12; the two connecting portions 112 are configured to be detachably connected to the inner wall 100, and the two connecting portions 112 are respectively connected to the two ends of the bearing portion 111 in the horizontal direction, and the height of the connecting portion 112 is greater than the height of the bearing portion 111. In the above-mentioned setting, the height of the connecting portion 112 is greater than the height of the bearing portion 111, so as to improve the stability of the connection with the inner wall 100, and the setting of the variable cross-section reduces the deadweight of the bearing portion 111 to a certain extent.

[0059] More specifically, the bottom end of the connecting portion 112 is connected to the bottom end of the bearing portion 111 through an oblique brace, so as to convert the load borne by the bearing portion 111 from a vertical direction to a horizontal direction, thereby making the load transfer more reasonable.

[0060] It is understandable that a bolt structure is provided on the connecting portion 112 , and the bolt structure is provided on the contact surface between the connecting portion 112 and the inner wall 100 , so that the connecting portion 112 can be unlocked or locked to the inner wall 100 .

[0061] Specifically, the first main frame 12 is formed by sequentially connecting a plurality of first units 121. The arrangement of the first units 121 enables construction personnel to assemble the first main frame 12 according to actual needs to ensure that the height is appropriate, thereby improving the practicality of the shaft formwork.

[0062] More specifically, the first unit 121 includes a plurality of first vertical rods 1211, a plurality of first cross rods 1212 and a plurality of diagonal braces, which together form a frame structure.

The number of the first cross rod 1212 and the diagonal braces is determined by the length of the first vertical rod 1211, and is used to ensure that the first vertical rods 1211 can be firmly connected, which is not limited here, and has a simple structure, high reliability, and is not easy to damage. The length of the first vertical rod 1211 can be set in a variety of ways according to the actual needs of the operation to form first units 121 of different lengths, which are convenient for selection according to actual needs.

[0063] Specifically, the second set frame 2 includes a second main frame 21 and a second limiting frame 22. The second limiting frame 22 is connected between the second main frame 21 and the inner wall 100, and the second limiting frame 22 is configured to be detachably connected to the inner wall 100.

[0064] More specifically, only one or two second limiting frames 22 can be provided. The two second limiting frames 22 are relatively arranged on both sides of the second main frame 21 in the horizontal direction and are respectively connected to the opposite inner walls 100 to improve the stability of the second set frame 2.

[0065] It is understandable that a bolt structure is provided on the second limiting frame 22 , and the bolt structure is provided on the contact surface between the second limiting frame 22 and the inner wall 100 , so that the second limiting frame 22 can be unlocked or locked to the inner wall 100 .

[0066] In this embodiment, the second limit frame 22 is two rectangular frame structures arranged opposite to each other. Each rectangular frame structure is composed of multiple triangular frame structures connected by bolts or welding. The structure is simple and easy to assemble. The hypotenuse of the triangle can play the role of oblique support to enhance the bending stiffness of the second limit frame 22.

[0067] In other embodiments, the second limiting frame 22 may also be an integral rectangular frame with diagonal braces disposed therein.

[0068] Specifically, the second main frame 21 is formed by connecting a plurality of second units 211 in sequence, and the sleeve cavity runs through the plurality of second units 211. The arrangement of the second units 211 allows construction personnel to assemble the second main frame 21 according to actual needs to ensure that the height is appropriate, thereby improving the practicability of the formwork.

[0069] More specifically, the second unit 211 includes a plurality of second vertical rods 2111, a second cross rod 2112 and an assembly piece 2113. The plurality of second vertical rods 2111 are evenly distributed around the circumference of the sleeve cavity, the second cross rod 2112 is connected to the circumference of the sleeve cavity, two adjacent second vertical rods 2111 are connected by the second cross rod 2112, the assembly piece 2113 is connected to the second vertical rod 2111, and the assembly piece 2113 of one second unit 211 can be connected to the assembly piece 2113 of another second unit 211. With the above arrangement, the plurality of second vertical rods 2111 and the second cross rod 2112 are arranged to form a sleeve cavity, and the adjacent second units 211 can be connected to each other through their respective assembly pieces 2113, which has a simple structure and is not easily damaged.

[0070] More specifically, the shaft formwork further includes a locking piece, and an assembly hole is provided on the assembly piece 2113, and the locking piece can be inserted into the assembly holes of the two second units 211. In this embodiment, the locking piece can be a bolt, a rivet or a pin.

[0071] In this embodiment, four second vertical rods 2111 are provided in each second unit 211. The length of the second vertical rods 2111 can be set in various ways according to the actual needs of the operation. The second cross rod 2112 is connected between two adjacent second vertical rods 2111. The diagonal brace rod is connected between the second vertical rod 2111 and the second cross rod 2112. The number of the second cross rod 2112 and the diagonal brace rod is determined by the length of the second vertical rod 2111, and is used to ensure that the second vertical rods 2111 are firmly connected. No limitation is made here. The structure is simple, the reliability is high, and it is not easy to be damaged.

[0072] Specifically, the second unit 211 is also provided with an adjustment component 2114, which can adjust the two second units 211 to align in the horizontal direction. The arrangement of the adjustment component 2114 enables the adjacent second units 211 to be aligned during the assembly of the second main frame 21, so as to reduce assembly errors.

[0073] More specifically, the adjustment assembly 2114 includes an adjustment sheet 21141, an adjustment bolt 21142 and an adjustment nut 21143. The adjustment sheet 21141 covers the outer side of the second crossbar 2112, and each adjustment sheet 21141 is provided with at least one adjustment bolt 21142; the adjustment bolt 21142 is passed through the adjustment sheet 21141 and the second crossbar 2112; the adjustment nut 21143 is screwed on the adjustment bolt 21142, and the adjustment nut 21143 and the adjustment bolt 21142 are against the outer side of the adjustment sheet 21141. With the above arrangement, the construction personnel can screw the adjustment bolt 21142 to make the adjustment nut 21143 press against the adjustment sheet 21141 along the length direction of the adjustment bolt 21142, thereby driving one second unit 211 to align with another second unit 211.

[0074] In this embodiment, the adjustment piece 21141 is connected to the second vertical rod 2111, and part of the adjustment piece 21141 is against the second cross rod 2112 and the outer side of the diagonal support rod at the same time, so as to adjust the angle of the diagonal support rod.

[0075] Specifically, a avoidance cavity is provided in the second limit frame 22, and a avoidance opening connected to the avoidance cavity is provided at the bottom end of the second limit frame 22, and part of the first sleeve frame 1 can extend into the avoidance cavity through the avoidance opening. Specifically, when the first sleeve frame 1 enters the sleeve cavity, the first limit frame 13 extends into the avoidance cavity through the avoidance opening. The setting of the avoidance cavity can prevent the first limit frame 13 from interfering with the second limit frame 22.

[0076] The shaft formwork further includes a pulley 4, which is disposed between the first frame 1 and the second frame 2. When the second frame 2 and the first frame 1 are moved closer to or farther from each other in the vertical direction, they can rotate around their own axes against the pulley 4. The arrangement of the pulley 4 enables the first main frame 12 and the second main frame 21 to generate rolling friction during relative motion, thereby preventing the first main frame 12 and the second main frame 21 from generating sliding friction during relative motion and reducing friction.

[0077] Specifically, the shaft formwork further includes a plurality of first bearing plates 5 and a plurality of second bearing plates 6. The plurality of first bearing plates 5 are arranged on the first frame 1 at intervals in the vertical direction, and a working plane is arranged on each first bearing plate 5; the plurality of second bearing plates 6 are arranged on the second frame 2 at intervals in the vertical direction, and a working plane is arranged on each second bearing plate 6.

Part of the second bearing plates 6 are connected to the support frame 11, and the remaining second bearing plates 6 can be arranged on the second main frame 21 at intervals according to construction needs, which is not limited here. The above arrangement makes it convenient for the staff to lock or unlock the first limiting frame 13, the second limiting frame 22 and the support frame 11 to the inner wall 100 on the working plane. In this embodiment, the first bearing plate 5 and the second bearing plate 6 can be welded or screwed to the first frame 1 and the second frame 2, respectively.

One end of the second connecting seat 32 is hinged to the other output end of the driving mechanism 33, and the other end is fixedly connected to the second main frame 21.

[0081] The following is a detailed description of the assembly and use of the well formwork:

[0082] The stroke length of the driving mechanism 33 is determined according to the actual operation requirements, and then the length of the first main frame 12 is determined according to the length, and multiple first units 121 are sequentially connected in the vertical direction to form the first main frame 12. The first connecting seat 31 is fixedly connected to the inside of the first main frame 12, and then one output end of the driving mechanism 33 is screwed to the first connecting seat 31. The supporting frame 11 is connected to the bottom end of the first main frame 12, and the first limiting frame 13 is connected to the first main frame 12.

[0083] According to the actual operation requirements, determine the length of the second main frame 21, and then connect the second units 211 in sequence along the vertical direction, align the assembly holes of the two adjacent second units 211, and install the locking piece in the assembly hole so that the second units 211 are initially locked and aligned. Under the premise of ensuring that one of the adjusting nut 21143 and the adjusting bolt 21142 is fixed, screw the other one so that the two adjacent second units 211 are completely aligned. Place the second connecting seat 32 inside the sleeve cavity and connect it to the second main frame 21, then sleeve the second main frame 21 on the outside of the first main frame 12, and the other output end of the driving mechanism 33 is screwed to the second connecting seat 32. The second limiting frame 22 is fixedly connected to the outside of the second main frame 21.

[0084] The first supporting plate 5 and the second supporting plate 6 are connected to the first housing frame 1 and the second housing frame 2 respectively.
