Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a simple material conveying device between upper and lower floors. Background Art

[0002] With the continuous development and improvement of the construction industry, the current construction industry has gradually shifted from an extensive management model to a lean construction model, and higher standards of management requirements have been put forward in terms of construction period management, process interlacing, and the use of turnover materials. For the use of formwork materials, timely dismantling and turnover can reduce material input, thereby reducing construction costs. Usually, the formwork of vertical components can be dismantled when the concrete strength can ensure that the surface and edges are not damaged, and the formwork of horizontal components can be dismantled after meeting the concrete strength requirements. Most of the dismantled formwork materials need to be circulated through the unloading platform, and as the floor height increases, a cantilevered unloading platform needs to be used, which has the defects of low material turnover efficiency, high use cost, and great safety hazards.

[0003] Therefore, how to provide a simple material transfer device between upper and lower floors for the timely turnover of materials between floors is a problem that technicians in this field urgently need to solve. Utility Model Content

[0004] In view of this, the utility model provides a simple material transfer device between upper and lower floors, which is arranged in the floor slab. After the concrete is poured and fixed, the simple material transfer function is realized. Under the premise of ensuring safety, the turnover efficiency of the formwork materials in the floor is greatly improved. At the same time, the turnover use of the unloading platform can be eliminated, saving construction costs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A simple material conveying device between upper and lower floors, comprising:

[0007] A material transfer frame, the material transfer frame having a material transfer opening penetrating the top surface and the bottom surface thereof and a first inner side surface and a second inner side surface arranged oppositely;

[0008] A roller, the roller is rotatably connected to the inner wall of the material transfer frame, the roller is arranged close to the first inner side surface and the central axis is perpendicular to the bottom surface;

[0009] A tooth plate, one end of which is hinged on the second inner side surface, and the other end of which is a tooth, wherein the tooth arrangement direction is parallel to the axis of the drum and a material transfer gap is formed between the two;

[0010] Anchor pieces, a plurality of said anchor pieces are fixed on the outer wall of said material transfer frame.

[0011] The beneficial effect of the above technical solution is that the material transfer device is pre-buried in the floor slab through the anchoring piece, and the formwork frame materials removed after the construction of the lower floor of the building is completed can be transported to the upper floor of the building through the material transfer port. After the formwork material enters the material transfer frame, the friction between the formwork frame materials and the roller is utilized, and the workers on the upper floor of the building pull the formwork frame materials to make the roller rotate, thereby completing the upward transfer of the formwork frame materials. The tooth plate abuts against the other side of the formwork frame materials, which can prevent the formwork frame materials from sliding down and falling, and can greatly improve the turnover efficiency of the formwork frame materials in the floor while ensuring safety.

[0012] Preferably, it further comprises a first support shaft, the two ends of which are respectively fixed on the two opposite inner walls of the material transfer frame, the roller is provided with a through hole in the axial direction and is sleeved on the first support shaft, and there is a rotation gap between the inner wall surface of the roller and the outer wall surface of the first support shaft.

The first support shaft and the second support shaft are symmetrically arranged along the two inner walls of the material transmission frame, the tooth plate is sleeved on the second support shaft through the sleeve, and the torsion spring is fixed with the second support shaft and the tooth plate to form an elastic connection relationship. When the material transmission device is not in use, the tooth plate is in a horizontal position under the elastic support of the torsion spring. When the material transmission device is in use, the template frame material will touch the rack, so that the tooth plate rotates upward along the second support shaft. During the rotation of the tooth plate, the rack abuts against the template frame material, and the template frame material slides downward by using the tooth plate and friction. After the template frame material is transferred upward, the tooth plate is reset under the action of the torsion spring.

[0014] Preferably, the length of the sleeve is less than the length of the second support shaft, and two torsion springs are provided, and the two torsion springs are symmetrically arranged along the two ends of the sleeve.

The material transfer of the template frame between floors can be carried out by continuously rotating the roller on one side of the material transfer frame to transfer the material upward, saving the labor of workers.

[0029] 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.

[0030] See attached Figures 1 to 4 The utility model discloses a simple material transfer device between upper and lower floors. The simple material transfer function is realized by pre-embedding the material transfer device in the floor slab and pouring and fixing the concrete, including:

[0031] A material transfer frame 1, wherein the material transfer frame 1 has a material transfer opening penetrating through the top and bottom surfaces thereof and a first inner side surface and a second inner side surface arranged oppositely;

[0032] The roller 3 is rotatably connected to the inner wall of the material transfer frame 1, and is arranged close to the first inner side surface and its central axis is perpendicular to the bottom surface;

[0033] A tooth plate 4, one end of which is hinged on the second inner side surface, and the other end of which is a tooth, and the tooth arrangement direction is parallel to the axis of the drum 3 and a material transfer gap is formed between the two;

[0034] Anchors 2 , multiple anchors 2 are fixed on the outer wall of the material transfer frame 1 .

[0035] like Figure 2 As shown, the material transfer frame is embedded in the floor slab. When the lower layer transfers the formwork frame material to the upper layer, the formwork frame material enters the material transfer frame through the material transfer port. The formwork frame material abuts against the roller. By utilizing the friction between the two, when the workers on the upper layer pull the formwork frame material upward, the roller rolls, and the formwork frame material can be easily transferred upward. At the same time, the rack on the tooth plate also abuts against the formwork frame material, which can prevent the formwork frame material from sliding downward, thereby improving safety performance.

[0036] In order to further optimize the above technical solution and improve the rotation performance of the drum, it also includes a first support shaft 6, the two ends of the first support shaft 6 are respectively fixed on the two opposite inner walls of the material transfer frame 1, and the drum 3 is provided with an axial through hole 31 and is sleeved on the first support shaft 6. There is a rotation gap between the inner wall surface of the drum 3 and the outer wall surface of the first support shaft 6.

[0037] In order to further optimize the above technical solution and ensure that the tooth plate can be reset after rotation, it also includes a second support shaft 7 and a torsion spring 5. The second support shaft 7 is fixed on the inner wall of the material transfer frame 1 relative to the first support shaft 6, and one end of the torsion spring 5 is fixedly connected to the outer wall of the second support shaft 7; a sleeve 41 is fixed on a side panel of the tooth plate 4, and the sleeve 41 is sleeved on the second support shaft 7, and the other end of the torsion spring 5 is fixedly connected to the panel of the tooth plate 4.

[0038] In this embodiment, the material transfer frame 1 is a rectangular frame welded from steel plates with a length of 1000 mm, a width of 200 mm, and a height of 100 mm, and the thickness of the steel plates is 3 mm.

[0039] In this embodiment, the roller 3 and the tooth plate 4 are parallel to the long axis direction of the material transfer frame 1 .

[0040] The length of the roller is the same as that of the tooth plate, and both are fixed on the long side of the material transfer frame. The roller and the tooth plate are symmetrically arranged on both sides of the long axis of the material transfer frame, such as Figure 4 As shown, when the material transfer device is in use, if it is necessary to transfer the template to the upper level of the building, the template removed from the lower level is transferred upward to the upper level of the building through the material transfer port, and one side wall of the template abuts against the outer wall of the drum. When the workers on the upper level pull the template upward, due to the friction between the template and the drum, the drum will rotate when the template is pulled upward, so that the template can be easily transferred upward, reducing the workers' effort in lifting materials. At the same time, when the template is transferred upward, the tooth plate will rotate upward to form a certain inclination angle under the action of the torsion spring, and the tooth plate abuts against the other side of the template. The transmission tooth plate plays a one-way control through the torsion spring, which can clamp the template in the material transfer frame to prevent the template from falling suddenly. The template is lifted to the upper mouth of the material transfer device by the workers on the lower level, and the workers on the upper level can pull it up through the transmission device to achieve template transfer. After the template transfer is completed, the tooth plate returns to its original position under the action of the torsion spring.

[0041] In order to further optimize the above technical solution, improve the one-way control effect of the tooth plate and ensure its self-resetting ability, the length of the sleeve 41 is less than the length of the second support shaft 7, and two torsion springs 5 ​​are provided, and the two torsion springs 5 ​​are symmetrically arranged along the two ends of the sleeve 41.

[0042] In this embodiment, the anchor 2 is a steel bar with a diameter of 10 mm and a length of not less than 200 mm.

[0043] In this embodiment, there are six anchors 2 in total, one end of the six anchors 2 is evenly welded to the outer wall of the material transfer frame 1, and the other end can be anchored in the floor slab.

[0044] In this embodiment, the material transfer frame 1 is anchored in the floor plate, and the material transfer port communicates between the upper and lower floors.

[0045] During the construction of the floor slab, a hole with the same size as the material transfer frame is reserved. The material transfer frame is set in the hole, and the anchor steel bars on the outer wall of the material transfer frame are welded and fixed to the floor slab steel bars. After the floor slab concrete is poured, the material transfer frame is embedded in the floor slab, and the material transfer port is connected with the upper and lower layers.

[0046] In order to further optimize the above technical solution, the straight-line distance between the rack and the outer wall of the drum 3 is not less than 200 mm.

[0047] In some other specific embodiments, a support plate 11 is fixed perpendicularly to the inner wall surface of the bottom end of the material transfer frame 1, and the two support plates 11 support the roller 3 and the gear plate 4 respectively.
