Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of enclosure devices, and particularly relates to an enclosure device for an aluminum formwork reserved hole. BACKGROUND

[0002] In the modern construction industry, with the increasing number of high-rise building projects, how to ensure the safety of the construction site has become the top priority. Especially in the process of using aluminum formwork for rapid construction, some holes are usually reserved on the floor slab to facilitate the transportation of formwork and other materials, which improves the construction efficiency but brings safety hazards.

[0003] In the prior art, the formed hole protection is often protected by a hole cover plate. Since the site is usually a floor hole (non-vertical hole), if the reserved hole is large, the cover plate may be affected by external forces and relative slip between the cover plate and the reserved hole, the protection effect is poor, and the overall safety of the construction site is seriously affected, so further improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the influence on the overall safety of the construction site, the present application provides an enclosure device for an aluminum formwork reserved hole.

[0005] The enclosure device for an aluminum formwork reserved hole provided by the present application adopts the following technical solution:

[0006] An enclosure device for an aluminum formwork reserved hole, comprising a formwork frame arranged at the reserved hole of the aluminum formwork, a first sealing ring arranged around the outer peripheral wall of the formwork frame, and a first fixing assembly for fixing the formwork frame to the aluminum formwork, the cross section of the formwork frame along its height direction is arranged in a trapezoidal shape, the area of the cross section of the formwork frame along the horizontal direction gradually increases towards the direction of its upper end surface, the height of the upper end surface of the formwork frame is higher than the height of the concrete to be poured on the aluminum formwork later, and the first sealing ring abuts against the aluminum formwork.

[0007] By adopting the above technical solution, since the aluminum formwork is arranged in a trapezoidal shape, it can be relatively adapted to the size required at the reserved hole, reducing the possibility of slipping out of the reserved hole. The first sealing ring is arranged to reduce the possibility of the subsequent poured concrete flowing out from the gap after the formwork frame is installed on the aluminum formwork. After being fixed by the first fixing assembly, since the height of the formwork frame is higher than the height of the concrete to be poured on the aluminum formwork later, it can also play a certain protection in the height direction after pouring and forming, which is relatively safe compared with directly covering the cover plate. Moreover, the increase in the height of the formwork frame itself is relatively simple and convenient, and the possibility of deformation due to the stress applied by the poured concrete is also relatively reduced.

[0008] Preferably, both the inner and outer side walls of the template frame are provided with a reflective layer.

[0009] By adopting the above technical solution and providing a reflective layer, a warning function can be played before and after pouring concrete.

[0010] Preferably, the lower end surface of the template frame is exposed on the lower surface of the aluminum mold top plate, and the first fixing assembly includes a first bolt passing through the side wall of the template frame and a first fixing plate fixedly connected to the lower surface of the aluminum mold top plate, and the first bolt is threadedly connected to the first fixing plate.

[0011] By adopting the above technical solution, the template frame is installed on the aluminum template top plate after the first bolt is passed through the side wall of the template frame and is threadedly connected to the first fixing plate.

[0012] Preferably, it also includes a trapezoidal body that is slidably inserted into the groove formed by the template frame and a second fixing component for installing the trapezoidal body on the template frame. The area of ​​the cross-section of the trapezoidal body along the horizontal direction gradually increases toward its own upper end face, and the height of the upper end face of the trapezoidal body is higher than the height of the upper end face of the template frame.

[0013] By adopting the above technical solution, since the template frame is usually thin, if a cover plate is directly rotated and connected to the template frame for sealing, the protection effect is limited. However, the trapezoidal main body is slidably inserted into the template frame and installed in the template frame on the peripheral side through the second fixing component. The through groove left in the middle of the template frame can be sealed, and the protection effect is relatively good.

[0014] Preferably, it further comprises a side stopper provided on the side of the upper end surface of the trapezoidal main body, and a plurality of the side stops are provided at intervals around the side of the trapezoidal main body.

[0015] By adopting the above technical solution, for some larger reserved openings, in order to reduce the possibility of subsequent cracks caused by stepping on the trapezoidal main body, side guards are provided for protection, thereby reducing the impact on the overall safety of the construction site.

[0016] Preferably, the lower end of the side stop is rotatably connected to the trapezoidal main body, and the trapezoidal main body is provided with a first limiting member for limiting the rotation of the side stop.

[0017] By adopting the above technical solution, when the side guard is rotated to be perpendicular to the upper end surface of the trapezoidal main body, it is then limited by the first limit member to provide protection in the height direction, thereby reducing the possibility of stepping directly on the trapezoidal main body, and is also convenient for folding for storage or transportation.

[0018] Preferably, a protective net is connected between adjacent side guards.

[0019] By adopting the technical scheme, the gap between the adjacent side guards is shielded by the protective net.

[0020] Preferably, the side guard is provided with four, the four side guards respectively include two first side guards parallel to the length direction of the trapezoidal main body and two second side guards parallel to the width direction of the trapezoidal main body, the second side guard includes a plurality of staggered scissors arms, the lower end of one of the first side guards is rotationally connected to the trapezoidal main body, and the trapezoidal main body is provided with a second limiting piece for fixing the two second side guards.

[0021] By adopting the technical scheme, the second side guard includes a plurality of staggered scissors arms, so that after unfolding, the first side guard is fixed by the second limiting piece to form protection in a certain height direction, and the two first side guards are conveniently folded and turned over for storage or transportation.

[0022] Preferably, the upper end surface of the trapezoidal main body is provided with a mounting groove for mounting the second fixing assembly, the second fixing assembly includes a second bolt penetrating the mounting groove, a sliding block rotationally connected to the lower end of the second bolt, a push rod abutting against the sliding block, and a connecting rope provided between the sliding block and the push rod; the trapezoidal main body is fixedly connected with a mounting plate at the groove opening of the mounting groove, the second bolt is threadedly penetrating the mounting plate, the sliding block slides along the height direction of the mounting groove, the side wall of the sliding block is provided with four guide surfaces, the push rod is provided with four and abuts against the four guide surfaces, and the side wall of the mounting groove is provided with a sliding groove for sliding connection of the push rod; the lower end surface of the trapezoidal main body is exposed to the lower end surface of the formwork frame, and the push rod is located at the lower end surface of the formwork frame.

[0023] By adopting the technical scheme, the second bolt is rotated forward to drive the sliding block to slide along the height direction of the mounting groove, and the guide surface pushes the push rod to move away from the trapezoidal main body, so as to push the push rod below the formwork frame, thereby reducing the possibility of the trapezoidal main body sliding out of the formwork frame under the influence of external force. And when the second bolt is rotated in reverse, the connecting rope drives the push rod to move towards the trapezoidal main body, so as to separate the trapezoidal main body from the formwork frame.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. The height of the formwork frame is higher than the height of the concrete poured on the aluminum mold top plate, so that a certain protection in the height direction can be achieved after pouring and forming, which is relatively simple and convenient, and the possibility of deformation can be reduced when the concrete is poured.

[0026] 2. By providing a trapezoidal main body, the through groove left in the middle of the template frame can be blocked, and the protection effect is better than the cover plate.

[0027] 3. For some larger reserved openings, in order to reduce the possibility of cracks caused by subsequent stepping on the trapezoidal main body, side guards are set for protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-8 , further details of this application are given.

[0038] An embodiment of the present application discloses a blocking device for a reserved hole in an aluminum mold top plate.

[0039] Example 1:

[0040] A retaining device for the reserved opening of the aluminum mold top plate, referring to Figure 1 、 Figure 2 The template frame 2 includes a template frame 2 disposed at a reserved opening 11 of the aluminum mold top plate 1, a first sealing ring 3 wound around the outer peripheral wall of the template frame 2, and a first fixing assembly 4 for fixing the template frame 2 to the aluminum mold top plate 1. It should be noted that the template frame 2 can be made of the same material as the aluminum mold top plate 1, or other materials, depending on the specific requirements.

[0041] In this embodiment, the cross-section of the template frame 2 along its height direction is trapezoidal, and the area of ​​the cross-section of the template frame 2 along the horizontal direction gradually increases toward its upper end face. The height of the upper end face of the template frame 2 is higher than the height of the concrete subsequently poured on the aluminum mold top plate 1, and the first sealing ring 3 abuts against the aluminum mold top plate 1. In this embodiment, since the template frame 2 will be disassembled later, the lower end face of the template frame 2 is exposed to the lower surface of the aluminum mold top plate 1, and the first sealing ring 3 specifically abuts against the lower surface of the aluminum mold top plate 1 to reduce the bonding area and degree between the concrete and the subsequently poured concrete for easy disassembly.

[0042] Furthermore, in order to improve the warning effect, in this embodiment, both the inner and outer side walls of the template frame 2 are provided with a reflective layer 21 .

[0043] The first fixing assembly 4 specifically includes a first bolt 41 passing through the side wall of the template frame 2 and a first fixing plate 42 fixedly connected to the lower surface of the aluminum mold top plate 1 , and the first bolt 41 is threadedly connected to the first fixing plate 42 .

[0044] The implementation principle of the enclosure device for the reserved opening of the aluminum formwork top plate in the embodiment of the present application is as follows: since the aluminum formwork itself is arranged in a trapezoidal shape, it can relatively adapt to the size required at the reserved opening 11, reducing the possibility of slipping away from the reserved opening 11, wherein the first sealing ring 3 is provided to reduce the possibility of the subsequently poured concrete flowing out from the gap after the gap appears when the formwork frame 2 is installed on the aluminum formwork top plate 1. After being fixed by the first fixing component 4, since the height of the formwork frame 2 is higher than the height of the concrete subsequently poured on the aluminum formwork top plate 1, it can also provide a certain degree of protection in the height direction after casting and forming, which is relatively safer than directly covering the cover plate, and since the height of the formwork frame 2 itself is increased, it is also relatively simple and convenient, and the possibility of deformation caused by the stress applied after concrete pouring is also relatively reduced.

[0045] Example 2:

[0046] Reference Figure 3 、 Figure 4The difference from Example 1 is that, in this embodiment, it also includes a trapezoidal main body 5 that is slidably inserted into the through groove 22 formed by the template frame 2 and a second fixing component 6 arranged on the trapezoidal main body 5 for fixing to the template frame 2. In this embodiment, the cross-section of the trapezoidal main body 5 along its height direction is trapezoidal, and the cross-section of the trapezoidal main body 5 along the horizontal direction gradually increases toward its own upper end face, and the height of the upper end face of the trapezoidal main body 5 is higher than the height of the upper end face of the template frame 2.

[0047] Among them, the second fixing component 6 can be specifically a spring buckle or other fasteners such as a spring hook 61, which can be set according to specific needs. In this embodiment, it is specifically set with a spring hook 61, one end of the spring hook 61 is fixedly connected to the side of the trapezoidal body 5, and the upper end surface of the template frame 2 is protruding with a hanging ring 23 for hanging the other end of the spring hook 61.

[0048] Furthermore, in order to improve the connection with the template frame 2, in this embodiment, a second sealing ring 51 is provided around the outer peripheral wall of the trapezoidal body 5 to abut against the inner side wall of the template frame 2 to reduce the possibility of slippage, separation or loosening.

[0051] The second bolt 62 is rotated forward to drive the slider 63 to slide along the height direction of the mounting slot 52, and the guide surface 631 pushes the push rod 64 in a direction away from the trapezoidal body 5, so that the push rod 64 is pushed below the template frame 2 to reduce the possibility of the trapezoidal body 5 sliding off the template frame 2 due to external forces. The fixing bolt is rotated backward to drive the push rod 64 in a direction toward the trapezoidal body 5 via the connecting rope 65, so as to separate the trapezoidal body 5 from the template frame 2.

[0053] Reference Figure 6 、 Figure 7 , differing from Example 2 in that it further includes side stops 7 disposed on the side of the upper end surface of the trapezoidal body 5. A plurality of side stops 7 are spaced around the side of the trapezoidal body 5, specifically four. The lower ends of the four side stops 7 are all rotatably connected to the trapezoidal body 5. A first stopper 8 is provided on the trapezoidal body 5 to restrict the rotation of the side stops 7. In this embodiment, the first stopper 8 includes a second fixing plate 81 fixedly connected to the side wall of the side stop 7 and a stopper bolt 82 threadedly inserted through the second fixing plate 81. The upper end surface of the trapezoidal body 5 defines a threaded hole for threadably engaging the stopper bolt 82.
