Description

Technical Field

[0001] The utility model relates to a corner structure of a prefabricated clean room, belonging to the technical field of clean rooms. Background Art

[0002] A clean room, also known as a dust-free room, is an enclosed space in which parameters such as air cleanliness, temperature, and humidity are controlled as required, and is applied to industries such as medical treatment, food workshops, and industries with high requirements for cleanliness.

[0003] At present, the corner structure of the ceiling inside the clean room generally adopts an arc angle. The purpose is to avoid the accumulation of dust and ash on the ordinary right-angle top corner structure after long-term use, which is extremely inconvenient for cleaning and cleaning, and ultimately leads to incomplete cleaning, affecting the cleanliness index inside the clean room.

[0004] However, in the existing operating rooms with arc-shaped corner structures, during the installation process, due to the poor stability of the arc angle installation structure, it is extremely easy to cause "gaps" or "holes" at the corners during use, resulting in dust entering the inside of the clean room, and ultimately reducing the cleanliness of the clean room. For example, the arc-shaped modular prefabricated structure of the operating room disclosed in the patent with the publication number CN210685510U. The corner structure of the operating room disclosed in this patent is installed on the vertical wall column through an arc-shaped corner piece, and other positions of the arc-shaped corner piece are not installed with other components, nor are they fixed in other ways. This will result in poor fixing effect of the arc-shaped corner piece after installation. During long-term use, the arc-shaped corner piece is easy to loosen, resulting in "gaps" or "holes" at the top corners of the clean room. In this way, a lot of dust will still enter the clean room, making it difficult to meet the index requirements of the final cleanliness. Summary of the Utility Model

[0005] The utility model solves the above technical problems. A brief overview of the utility model is given below to provide a basic understanding of certain aspects of the utility model. It should be understood that this overview is not an exhaustive overview of the utility model. It is not intended to identify the key or important parts of the utility model, nor is it intended to limit the scope of the utility model.

[0025] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0026] Specific implementation manner one: With reference to Figures 1-10 To illustrate this implementation manner, an assembled clean room corner structure of this implementation manner includes a wall column 1, a cross beam 2, a first corner connecting piece 3, an intermediate connecting piece 4 and a second corner connecting piece 5. The cross beam 2 is placed on the wall column 1 to form a roof frame 6. Wall panels 7 are installed on both sides of the wall column 1, and the cross beam 2 is installed at the top of the wall panel 7. The first corner connecting piece 3, the intermediate connecting piece 4 and the second corner connecting piece 5 are respectively installed at the top of the wall column 1;

[0027] The cross-sectional structures of the cross beam 2, the first corner connecting piece 3 and the second corner connecting piece 5 are the same, and each includes a connecting piece main body 8. The connecting piece main body 8 includes a triangular body 9 and a square body 10. The hypotenuse of the triangular body 9 is arc-shaped. An upper installation groove 11 is provided on the upper end surface of the triangular body 9, a side installation groove 12 is provided on one side of the square body 10, and a lower installation groove 13 is provided at the lower end of the square body 10;

[0028] The inner top corner of the roof frame 6 formed by assembling the wall columns 1, cross beams 2, first corner connectors 3, intermediate connectors 4 and second corner connectors 5 forms an "arc-shaped transition surface".

[0029] The wall column 1 includes a straight section 14 and connecting parts 15 arranged at both ends of the straight section 14. The connecting parts 15 are provided with a first installation groove 16 and a second installation groove 17. The first corner connector 3 and the second corner connector 5 are respectively installed on the connecting parts 15 of the wall column 1, and the intermediate connector 4 is installed on the straight section 14 of the wall column 1.

[0030] The cross-section of the intermediate connector 4 is a "triangle" structure. The upper end of the intermediate connector 4 is provided with an upper insertion groove 18, and the side wall of the intermediate connector 4 has an L-shaped connecting rib 19. The L-shaped connecting rib 19 and the intermediate connector 4 form a clamping groove 20. The intermediate connector 4 is inserted on the straight section 14 through the L-shaped connecting rib 19.

[0031] In this embodiment, an assembled clean room corner structure, the specific installation structure is: assemble and combine the column 1 and the wall panel 7, and place the cross beam 2 on the wall column 1 to form the roof frame 6. Then insert the intermediate connector 4 on the rib plate of the straight section 14 through the L-shaped connecting rib 19. Subsequently, install the first corner connector 3 and the second corner connector 5 on the connecting parts 15 at both ends of the straight section 14 respectively, and adjust the relative positions of the first corner connector 3, the intermediate connector 4 and the second corner connector 5 on the wall column 1 to make them relatively neat and reliable. And make the corner structure installed stably and reliably in the following ways:

[0032] (1) As Figure 6 shown: The second corner connector 5 and the adjacent cross beam 2 and wall column 1 are fixedly installed through the L-shaped corner connector 23. Specifically, a buried nut 21 is installed in the second installation groove 17 of the wall column 1, and a first plug-in 32 is inserted into the side installation groove 12 of the second corner connector 5 and the cross beam 2. The first plug-in 32 is a "cross"-shaped plug-in, and threaded holes are processed at both ends of the first plug-in 32. The L-shaped corner connector 23 is provided with through holes corresponding to the first plug-in 32 and the buried nut 21, and bolts are installed in the through holes. The bolts on the L-shaped corner connector 23 are connected and installed with the buried nut 21 and the threaded holes on the first plug-in 32, so as to fixedly install the second corner connector 5, the adjacent cross beam 2 and the wall column 1. This installation method improves the structural strength at the corner of the clean room, and the assembled connection structure has the advantages of convenient installation, time-saving and labor-saving, and reliable installation structure.

[0033] (2) As Figure 6 shown: Insert a second plug-in 22 into the upper installation groove 11 of the second corner connector 5 and the upper installation groove 11 of the adjacent cross beam 2. The structure of the second plug-in 22 is the same as that of the first plug-in 32 (asFigure 7 As shown, threaded holes are provided at both ends of the second plug-in member 22, and screws or bolts are installed in the threaded holes. By screwing the screws or bolts, the position of the second plug-in member 22 in the installation groove 11 is limited, so as to firmly install the second corner connecting member 5 and the adjacent cross beam 2. Similarly, the first corner connecting member 3 is firmly installed with the adjacent cross beam 2 in the same way;

[0034] (3) An intermediate connecting member 4 is connected and installed between the first corner connecting member 3 and the second corner connecting member 5. The installation relationship among the three is as follows: a corner connecting plate 24 is inserted into the upper installation grooves 11 of the first corner connecting member 3 and the second corner connecting member 5. Both ends of the corner connecting plate 24 are provided with tightening screws 25. By screwing the tightening screws 25, the corner connecting plate 24 is tightened in the installation groove 11. Furthermore, through the corner connecting plate 24, the first corner connecting member 3 and the second corner connecting member 5 are respectively and firmly installed with the intermediate connecting member 4, improving the installation structural stability of the intermediate connecting member 4 and effectively reducing the problem that dust enters the clean room due to "gaps" or "holes" caused by the insufficiently firm installation structure between the intermediate connecting member 4 and the first corner connecting member 3 and the second corner connecting member 5.

[0035] In this embodiment, the first corner connecting member 3 and the second corner connecting member 5 are respectively combined with the intermediate connecting member 4 to form an arc-shaped corner structure, rather than directly cutting the cross beam 2 and assembling it with the intermediate connecting member 4. This is because the first corner connecting member 3 and the second corner connecting member 5 can be cut in the factory area using a small cutting machine, and the on-site installation is flexible. For cutting the cross beam 2, since the cross beam 2 is used in a clean room, the general specification length of the clean room is 6 meters or more, and the length of the cross beam 2 is generally the same as the length of the clean room. If the cross beam 2 is cut to form an oblique angle, a large cutting machine or equipment is required, which increases the processing cost. Therefore, the combined assembly form of the first corner connecting member 3 and the second corner connecting member 5 respectively with the intermediate connecting member 4 not only can reduce the manufacturing cost but also can achieve the advantage of reliable structure installation.

[0036] Specific embodiment two: Combine Figures 1-10To describe this embodiment, a corner structure of a prefabricated clean room in this embodiment further includes a locking plate 27. A locking nut 26 is inserted into the side mounting groove 12 of the cross beam 2. The locking plate 27 is installed on the locking nut 26 through a bolt. A locking opening 29 is formed between the locking plate 27 and the side wall of the triangular body 9. When the cross beam 2 is installed in cooperation with the wall panel 7, the wall panel 7 is inserted into the locking opening 29 formed by the locking plate 27 and the triangular body 9. By screwing the bolt on the locking plate 27, the cross beam 2 and the wall panel 7 are clamped by the locking plate 27. In addition, the bottom of the locking plate 27 has a bent portion and forms a wire routing groove 31. In this way, the wire routing groove 31 can be used for the installation of wire harnesses in the clean room. The wire harnesses used in the clean room are installed in the wire routing groove 31, which improves the installation neatness of the wire harnesses.

[0037] Specific Embodiment 3: In combination with Figures 1-12 To describe this embodiment, a corner structure of a prefabricated clean room in this embodiment. In this embodiment, the cross beam 2 can also be a symmetrical structure, that is, the cross beam 2 includes a square body 10 and triangular bodies 9 symmetrically arranged on both sides of the square body 10. In this way, when two adjacent clean rooms need to be built, the cross beam 2 in this embodiment is installed on the intermediate wall, and the two clean rooms share one cross beam 2.

[0038] In addition, when two adjacent clean rooms need to be built, use a Figure 11 T-shaped wall column 30 as shown as the connecting wall column between two adjacent clean rooms. When the T-shaped wall column 30 is used as a structural column, the T-shaped wall column 30 can be used as a load-bearing column and can bear the force of the wall panels of two adjacent clean rooms, and has the advantages of convenient installation.

[0039] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined. Those skilled in the art can exhaust all possibilities according to the mathematical knowledge of permutation and combination. Therefore, the present invention will no longer describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by the present invention.

[0040] This embodiment is only an exemplary description of this patent and does not limit its protection scope. Those skilled in the art can also make partial changes to it. As long as it does not exceed the spiritual essence of this patent, it is within the protection scope of this patent.
