Description

Technical Field

[0001] The utility model belongs to the technical field of construction column casting, in particular to a one-time supporting and fastening mould for a corbel at the top of a construction column without chiseling. Background Art

[0002] A structural column refers to a reinforced concrete column that is set at an appropriate position within the masonry of a house and connected to a ring beam in order to enhance the integrity and stability of the building, forming a spatial frame that can resist bending and shearing. It is an effective measure to prevent the collapse of a house.

[0003] During the construction of the secondary structure of a traditional house, a large number of structural columns need to be constructed. During the traditional structure construction process, since the top of the structural column cannot be cast densely, it is necessary to set a trumpet-shaped casting port (corbel structure) on the top plate of the structural column. Although this can ensure the density of the top of the structural column, the protruding part needs to be chiseled off after the formwork is removed, which not only reduces the construction efficiency, but also increases the construction workload.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Embodiment 1:

[0026] Reference Figure 1 to Figure 2 As shown, this embodiment provides a one-time formwork fastening mold for the top corbel of a structural column that does not require chiseling, including a structural column mold 1 arranged on the front and rear sides of a filling wall 3, a concrete top beam 4 fixedly connected to the top of the filling wall 3, and a top edge of the structural column mold 1 flush with the bottom edge of the concrete top beam 4. A slot is provided in the middle and upper part of one of the structural column molds 1, and a chiseling-free structure is movably connected in the slot.

[0027] A further optimized solution is that the chiseling-free structure includes a chiseling-free plate 2, on the inner wall of which one end of a screw 10 is threadedly connected, and the other end of the screw 10 extends out of another structural column mold 1 and is detachably connected to the structural column mold 1.

[0028] To further optimize the solution, the bottom edge of the chiseling-free plate 2 is rotatably connected to the slot via a hinge.

[0029] In this embodiment, the chiseling-free structure is rotatably connected to the structural column mold 1, and the chiseling-free structure can be closed according to the pouring situation. The corbel does not need chiseling and is formed in one step, thereby improving the construction efficiency.

[0030] Embodiment 2:

[0031] Reference Figures 3 to 10 As shown, the difference between this embodiment and embodiment 1 is that:

[0032] An angle adjustment structure 5 is fixedly connected to the bottom of the chiseling-free plate 2 , and a rotation groove 9 is provided on the structural column mold 1 with a slot. The angle adjustment structure 5 is located in the rotation groove 9 , and the angle adjustment structure 5 can adjust the angle of the chiseling-free plate 2 .

[0033] According to a further optimization scheme, the angle adjustment structure 5 includes a rotating shaft 501, which is fixedly connected to the chiseling-free plate 2 and is an integrated structure. An operating rod 502 is fixedly connected to one end of the rotating shaft 501, and a clamping structure is fixedly connected to the other end of the rotating shaft 501. The clamping structure is used to fix the angle of the chiseling-free plate 2.

[0034] In a further optimized solution, the engaging structure includes a rotating clamping block 503, the rotating clamping block 503 is fixedly connected to the rotating shaft 501, and a plurality of first clamping teeth are fixedly connected along the axis on the end surface of the rotating clamping block 503 away from the rotating shaft 501;

[0035] The first latching tooth is meshed with a moving block 504, and a plurality of second latching teeth are fixedly connected along the axis on the end surface of the moving block 504 close to the first latching tooth, and the second latching teeth are meshed and connected with the first latching teeth. One end of a spring 505 is fixedly connected to the end surface of the moving block 504 away from the second latching teeth, and the other end of the spring 505 is in contact with a fixed seat 506. The moving block 504 is slidably arranged in the rotating groove 9, and the fixed seat 506 is fixedly connected to the structural column mold 1;

[0036] A through hole 507 is provided at the axis of the fixed seat 506, and a pull rod 508 is slidably penetrated in the through hole 507. The pull rod 508 is an L-shaped structure, and one end of the pull rod 508 penetrates the fixed seat 506 and is fixedly connected to the movable clamping block 504. When the structure is used, the pull rod 508 is first manually pulled to drive the movable clamping block 504 to move away from the first clamping tooth, so that the second clamping tooth is separated from the first clamping tooth, and then the angle of the chiseling-free plate 2 is adjusted by manually rotating the operating rod 502, and the pull rod 508 is released. With the help of the elastic potential energy of the spring 505, the movable clamping block 504 moves close to the first clamping tooth, so that the first clamping tooth is meshed with the second clamping tooth, and the angle adjustment and locking are completed.

[0037] In a further optimized solution, the diameter of the spring 505 is larger than the diameter of the through hole 507 to ensure that the spring 505 contacts the fixing seat 506 and does not pass through the through hole 507 .

[0038] A further optimized solution is that a grouting port 6 is opened in the middle of the chiseling-free plate 2, a grouting pipe 602 is passed through the grouting port 6, the size of the grouting pipe 602 is matched with the size of the grouting port 6, and a grouting cover 601 is detachably connected to the surrounding side of the grouting pipe 602.

[0039] According to a further optimization scheme, a slurry outlet 7 is provided on the top of the chiseling-free plate 2, a slurry outlet pipe 702 is passed through the slurry outlet 7, the size of the slurry outlet pipe 702 is matched with the size of the slurry outlet 7, and a slurry outlet cover 701 is detachably connected to the surrounding side of the slurry outlet pipe 702.

[0040] A further optimization scheme is that a return grouting port 8 is provided below the chiseling-free plate 2 . The return grouting port 8 is opened on the structural column mold 1 and penetrates from directly below the chiseling-free plate 2 to the side wall of the structural column mold 1 away from the filling wall 3 .

[0041] When slurry flows out of the grouting port 8, it means that the slurry has reached the bottom end of the chiseling-free plate 2. At this time, the chiseling-free plate 2 is closed, and the external grouting structure is connected through the grouting port 8 to make the slurry flow back to the grouting port 8 at the top. At this time, the grouting port 8 is blocked. When the chiseling-free plate 2 is closed, the remaining part can be grouted by connecting the grouting pipe 602 with the external grouting structure. When slurry flows out of the slurry outlet 7, it proves that the grouting has been completed. The external grouting structure is connected to make the slurry flow back to the inlet end of the slurry outlet pipe 702, and the outlet end of the slurry outlet pipe 702 is blocked through the slurry outlet cover 701. The grouting cover 601 blocks the outlet end of the grouting pipe 602, and the template casting is completed.
