Description

Technical Field

[0001] The utility model relates to the technical field of building engineering templates, in particular to a reinforced material transfer port box. Background Art

[0002] In prefabricated buildings, the aluminum alloy formwork system is a new type of formwork system. The aluminum alloy formwork is made by extruding special equipment. It is a universal accessory composed of aluminum panels and frames. It can be assembled into a complex overall formwork of different sizes. It is a system aluminum formwork for assembly and industrialized construction. Compared with traditional wooden formwork and steel formwork, aluminum formwork is convenient in construction, shortens the construction period, can be recycled and reused many times, has good product quality, and is widely used in prefabricated buildings. When building an aluminum alloy formwork system, a material transfer port is left on the formwork for the transfer of the formwork, which is convenient for the formwork to be transferred upward manually without occupying vertical transportation equipment. A material transfer device for transferring aluminum formwork is installed at the material transfer port.

[0003] When pouring concrete on the formwork, the concrete is easy to fall and stick to the inner wall of the installed transfer port box and solidify, which increases the overall weight of the transfer port box. The outer wall of the transfer port box will also stick to the concrete. Therefore, the operator needs to use a lot of force to remove the transfer port box from the solidified concrete. The existing transfer port boxes mostly use square through tubes as handles. The contact area between the square through tube and the outer shell is small. Under the action of force, the connection between the handle and the inner wall of the traditional transfer port box is prone to breakage, which may cause the transfer port box to fall and injure the operator, posing a great safety hazard. Utility Model Content

[0004] One of the purposes of the utility model is to provide a reinforced material transfer port box to solve the problem in the prior art that the connection between the material transfer port box handle and the box inner wall is prone to breakage.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A reinforced material transfer port box comprises two shells and handles respectively mounted on the shells, the shell comprising a mounting plate and a first material transfer frame, a second material transfer frame and a fixed frame fixed to the mounting plate in a vertical direction and connected in sequence, the first material transfer frame, the second material transfer frame and the fixed frame are arranged in a stepped manner and their horizontal cross-sectional areas become smaller in sequence, the handle comprises a gripping portion and reinforcement portions arranged at both ends of the gripping portion, one end of the reinforcement portion away from the gripping portion is connected to the inner wall of the shell and extends along the inner wall of the shell toward the fixed frame, the two shells are connected by a mounting plate and fixed by a locking member.

[0007] In the above technical solution, the operator installs the material transfer port box at a selected position on the formwork, then pours concrete into the formwork. After the concrete solidifies and takes shape, the material transfer port box is removed, and the shape of the outer wall of the material transfer port box will be presented. The material transfer port box includes two detachable shells, and each shell is provided with a handle. Compared with a single handle, the two handles bear force more evenly, reducing the load on the connection between the handle and the outer shell, and reducing the risk of fracture. At the same time, the box body can be disassembled into two parts. The single shell is smaller in volume and lighter in weight than the whole box body, which is convenient for the operator to carry. The two shells can be kept relatively fixed under the action of the locking piece, and the stability is better. The first material transfer frame, the second material transfer frame and the fixed frame are designed in a stepped distribution and the horizontal cross-sectional area decreases in turn. Therefore, the contact surface between the outer wall of the material transfer port box and the concrete is also stepped. Compared with the flat contact surface, when the concrete is formed and the material transfer port box is pulled out, the frictional force and the force generated by adhesion on the outer wall of the stepped shell are smaller, so that less force is required to pull out the material transfer port box, reducing the load on the connection between the handle and the outer shell, and reducing the risk of fracture. At the same time, the stepped material transfer port can directly place steel bars during later filling, avoiding manual hole planting and steel bar supplement in the later stage, saving labor costs. The handle is provided with a reinforcement part, and the connection area with the inner wall of the shell is larger than that of a common square through pipe, reducing the risk of fracture and having better safety.

[0008] Preferably, the shell and the handle are integrally formed. This improves the firmness between the handle and the inner wall of the shell, reduces the risk of fracture, has better safety, and at the same time, the integral forming improves the production efficiency and is convenient for large-scale production.

[0009] Preferably, the holding part is U-shaped, and the arc end of the holding part is closer to the fixed frame than the other end. The holding part is designed to be U-shaped. Compared with a square handle, the contact area between the U-shape and the operator's palm is larger, reducing the pressure of the handle on the human hand and improving the comfort of the operator using the material transfer port box.

[0010] Preferably, it further includes a cover plate. A cavity is arranged inside the handle, and the cover plate is fixed on the handle and covers the cavity. The arrangement of the cavity reduces the materials required for manufacturing, so the weight of the whole material transfer port box is reduced, the load on the connection between the handle and the outer shell is reduced, the risk of fracture is reduced, and the safety is better. The design of the cover plate covers the cavity to prevent concrete from falling into the cavity, resulting in an increase in the overall weight of the material transfer port box.

[0011] Preferably, the cover plate is provided with insertion posts, and the handle is provided with insertion holes matching the insertion posts, and the insertion posts are installed in the insertion holes. The detachable design between the cover plate and the handle is convenient for the operator to disassemble and carry. When not in use, it can be disassembled and separated, which is convenient for storage and has better convenience.

[0012] Preferably, the cover plate further comprises a handle and an engraving portion. The design of the handle facilitates the operator to take out the cover plate, which is more convenient. The engraving portion can be engraved with relevant information on it to serve as a reminder, which is more convenient.

[0013] Preferably, the locking members are bolts and nuts, and the mounting plate is provided with a plurality of corresponding through holes. The bolts pass through the corresponding through holes on the two mounting plates in turn and are threadedly connected with the nuts to fix the two shells. The two tightly fitting mounting plates support the inner walls of the shells, thereby reducing the deformation of the material transfer port box due to the extrusion of concrete, thereby causing deviations in the shape of the material transfer port. The coordination between the bolts and nuts is convenient for assembly and disassembly, which speeds up the on-site construction rate. When the material transfer port box is not in use, the two shells can be quickly disassembled and separated, which is convenient for storage and better convenience.

[0014] Preferably, the first material transfer frame and the second material transfer frame are tapered. When the material transfer port box is installed on the template, the material transfer port box can automatically align and level the template under the action of gravity, so that the hole surface of the material transfer port is smooth and regular in size when the template is removed after concrete pouring. At the same time, it is more convenient to plant reinforcement when the material transfer port is blocked later. The reinforcement is loaded from the large end of the material transfer port and clamps the inner wall of the material transfer port, which has better stability, avoids roughening of the material transfer port later, and is more convenient.

[0015] Preferably, the fixing frame is provided with a fixing part, and the fixing part is used to fix the shell on the template, thereby improving the stability of the shell, avoiding the deviation of the shape of the material transfer port due to the movement of the material transfer port box when pouring concrete, and improving the accuracy.

[0016] Preferably, it also includes a support plate, the two ends of which are fixed to the inner wall of the shell, providing support for the shell, reducing the deformation of the material transfer port box caused by the extrusion of concrete, thereby causing the material transfer port shape to deviate, and achieving better accuracy.

[0017] Beneficial effects of the utility model: The stepped design of the device reduces the friction and adhesion of the outer wall of the shell to the concrete, reduces the load-bearing at the connection between the handle and the shell, and reduces the risk of fracture at the connection between the handle and the shell. The handle is provided with a reinforcement portion, which increases the contact area between the handle and the inner wall of the shell, and reduces the risk of fracture at the connection between the handle and the shell. The above design makes the overall safety of the device better, and prevents the operator from falling and injuring himself when lifting the material transfer box due to the fracture of the connection between the handle and the inner wall of the shell.

[0023] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] Example 1

[0026] like Figures 1-4The example 1 of a reinforced material transfer port box is shown, comprising two shells 1, handles 2 respectively mounted on the shells 1, and a cover plate 4. The shells 1 and the handles 2 are integrally formed, and can also be fixed by threaded connection, riveted connection or welding. The shell 1 comprises a mounting plate 101 and a first material transfer frame 102, a second material transfer frame 103 and a fixed frame 104 which are fixed on the mounting plate 101 in a vertical direction and are connected in sequence. The first material transfer frame 102, the second material transfer frame 103 and the fixed frame 104 are distributed in a stepped manner and the horizontal cross-sectional areas decrease in sequence. The first material transfer frame 102 and the second material transfer frame 103 are conical. The handle 2 comprises a gripping portion 201 and a reinforcement portion 202 arranged at both ends of the gripping portion 201. The end of the reinforcement portion 202 away from the gripping portion 201 is connected to the inner wall of the shell 1 and extends along the inner wall of the shell 1 toward the fixed frame 104, and The inner wall of the first material transfer frame 102 and the second material transfer frame 103 are connected. In addition, the reinforcement part 202 can also extend horizontally or in all directions. The holding part 201 is U-shaped. In addition, it can also be any arc shape with a large palm-fitting area. The arc end of the holding part 201 is closer to the fixed frame 104 than the other end. A cavity is provided inside the handle 2, and a plug post 401 is provided on the cover plate 4. A socket 203 matching the plug post 401 is provided on the handle 2. The plug post 401 is installed in the socket 203 and the cover plate 4 covers the cavity. Each cover plate 4 also includes two handles 402 and an engraving part 403.

[0027] Specifically, during the actual installation of the material transfer port box, the operator installs the material transfer port box at a selected position on the formwork, then pours concrete into the formwork. After the concrete solidifies and takes shape, the material transfer port box is removed, and the shape of the outer wall of the material transfer port box will be presented. The material transfer port box includes two detachable shells 1 and a handle 2 integrally formed with the shell 1. There is a cavity inside the handle 2. The cover plate 4 is fixed on the handle 2 through the cooperation of the insertion post 401 and the insertion hole 203 and covers the cavity. The detachable design between the cover plate 4 and the handle 2 enables disassembly, facilitating the operator's handling. When not in use, it can be disassembled and separated for convenient storage, with better convenience. When the operator wants to disassemble the cover plate 4, they only need to hold the two handles 402 with both hands and lift upward to separate the cover plate 4 from the handle 2. The cover plate 4 is also provided with an engraving part 403, on which the specification size, usage information, enterprise trademark, etc. of the material transfer port box can be engraved during the production process. At the same time, the material transfer port box can be disassembled into two shells 1. Each single shell 1 has a smaller volume and lighter weight compared to the entire box body, facilitating the operator's handling. The first material transfer frame 102, the second material transfer frame 103, and the fixed frame 104 are designed in a stepped distribution with gradually decreasing horizontal cross-sectional areas. Therefore, the contact surface between the outer wall of the material transfer port box and the concrete is also stepped. Compared with a flat contact surface, when the material transfer port box is pulled out after the concrete has formed, the frictional force and the force generated by adhesion on the outer wall of the shell 1 are smaller. At the same time, the stepped material transfer port can directly place steel bars during later filling, avoiding post-planting hole reinforcement. Under the action of gravity, the tapered first material transfer frame 102 and the second material transfer frame 103 will automatically align and level the formwork, making the hole surface of the material transfer port smooth and the size regular after the concrete is poured and the formwork is removed. At the same time, it makes the post-implantation of steel bars more stable during the later sealing of the material transfer port. The steel bars are inserted from the large end of the material transfer port and are stuck to the inner wall of the material transfer port, avoiding the need for later chiseling of the material transfer port, with better convenience.

[0028] The beneficial effects of this embodiment: The stepped design of the device, the integrated design of the handle 2 and the shell 1, and the design of the reinforcement part 202 all make the connection between the handle 2 and the shell 1 more stable, reducing the risk of fracture and avoiding the shell 1 falling and injuring the operator due to the fracture at the connection between the handle 2 and the inner wall of the shell 1. The U-shaped design of the holding part 201 reduces the pressure of the handle 2 on the human palm, improving the comfort of the operator when handling the material transfer port box. The design of the cover plate 4 covers the cavity, preventing concrete from falling into the cavity and increasing the overall weight of the material transfer port box. The setting of the insertion post 401 and the insertion hole 203 makes the cover plate 4 and the handle 2 detachable, facilitating handling and storage, and the engraving part 403 clearly displays the information of the material transfer port.

[0029] Embodiment 2

[0030] Such as Figure 1 And Figure 2Shown is Embodiment 2 of a reinforced material transfer port box, which includes two housings 1. The housing 1 includes a mounting plate 101 and a first material transfer frame 102, a second material transfer frame 103, and a fixing frame 104 that are fixedly connected in sequence along the vertical direction on the mounting plate 101. The first material transfer frame 102, the second material transfer frame 103, and the fixing frame 104 are distributed in a stepped manner and their horizontal cross-sectional areas decrease in sequence. The first material transfer frame 102 and the second material transfer frame 103 are conical. The two housings 1 are connected through the mounting plate 101 and fixed by a locking member 3. In this embodiment, the locking member 3 is a bolt 301 and a nut 302. A number of corresponding through holes 1011 that are evenly distributed on the mounting plate are provided on both mounting plates 101. The bolt 301 passes through the corresponding through holes 1011 on the two mounting plates 101 in sequence and is threadedly connected to the nut 302.

[0031] Specifically, the bolt 301 and the nut 302 are threadedly connected to fix the two housings 1. The two tightly fitting mounting plates 101 play a supporting role for the inner wall of the housing 1, reducing the situation where the shape of the material transfer port deviates due to the deformation of the material transfer port box caused by the extrusion of concrete, making the material transfer port obtained after pouring more regular and more accurate. The threaded connection between the bolt 301 and the nut 302 is convenient for disassembly and assembly, accelerating the construction speed on site. When the material transfer port box is not in use, the two housings 1 can be quickly disassembled and separated, facilitating storage and having better convenience.

[0032] The remaining features and technical effects of this embodiment are the same as those of Embodiment 1.

[0033] Embodiment 3

[0034] As Figure 4 Shown is Embodiment 3 of a reinforced material transfer port box. The difference from Embodiment 1 and Embodiment 2 is that a fixing portion 105 is provided on the fixing frame 104. The fixing portion 105 is used to fix the housing 1 on the formwork. In this embodiment, the fixing portion 105 includes a thickening piece 1051 provided on the inner wall of the fixing frame 104 and a fixing hole 1052 provided on the thickening piece 1051. The bolt can pass through the fixing hole 1052 and be connected to the formwork to achieve fixation. The thickening piece 1051 lengthens the length of the fixing hole 1052, making the contact area between the bolt and the housing 1 larger, improving the stability of the housing 1 fixed on the formwork, and avoiding the deviation of the shape of the material transfer port caused by the movement of the material transfer port box during concrete pouring, with better accuracy. The material transfer port box also includes four equally spaced support plates 5. Both ends of the support plate 5 are fixed to the inner walls of the second material transfer frame 103 and the fixing frame 104, providing a supporting effect for the housing 1, reducing the situation where the shape of the material transfer port deviates due to the deformation of the material transfer port box caused by the extrusion of concrete, and at the same time reducing material loss.

[0035] The remaining features and technical effects of this embodiment are the same as those of Embodiment 1 and Embodiment 2.

[0036] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
