Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure construction, and in particular relates to a side wall shielding steel plate fixing structure of a large darkroom. Background Art

[0002] When the electromagnetic compatibility chamber is used for product testing, because the types and sizes of products are different, including various large military equipment such as aircraft, the test space of these equipment is relatively large, so the size of the chamber needs to reach a height of more than 20m. At this height, the overall weight of the side wall steel plate will be relatively large. If these side wall steel plates are still connected in a conventional way, the corresponding construction accuracy requirements will be very high while meeting the verticality requirements of the chamber construction. If the construction accuracy does not meet the requirements, the risk will be relatively large;

[0003] The existing technology is to drill holes in the side wall steel plate and connect the steel plate to the external steel structure with a screw rod. However, in this way, the overall weight of the steel plate and the external steel structure still falls on the bottom steel plate, which can easily cause deformation of the bottom steel plate, that is, it will still change the verticality of the side wall steel plate relative to the bottom steel plate. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a side wall shielding steel plate fixing structure for a large darkroom.

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

[0006] A side wall shielding steel plate fixing structure for a large darkroom, comprising a ring beam and a side wall steel plate used in the construction of the darkroom, wherein the side wall steel plate is screwed to a side wall fixing piece, the side wall fixing piece is vertically mounted on the side wall steel plate, the side wall fixing piece is parallel to the upper horizontal plane of the ring beam, the side wall fixing piece is provided with four fixing holes, locking screws are placed in the four fixing holes, and the locking screws are threadedly connected to fastening nuts on both upper and lower sides of the fixing holes;

[0007] The two sides of the ring beam are symmetrically installed with jaw clamps, and the ring beam is installed with an iron plate through the jaw clamps. The iron plate is provided with a countersunk hole, and the locking screw is located in the countersunk hole.

[0008] It is further defined that a reinforcing support structure is installed between the side wall fixing member and the iron plate;

[0009] The reinforced supporting structure includes two fork rows, the ends of the fork rows are integrally connected with supporting blocks, the supporting blocks are provided with inclined surfaces, the two fork rows are slidably installed with capped screws, the ends of the two capped screws are threadedly connected with pull cylinders, the threads of the pull cylinders are opposite to the threaded connection of the two capped screws, and the outer side surfaces of the pull cylinders are integrally connected with hexagonal screw caps. Such a design, by locking the pull cylinders, allows the supporting blocks installed in opposite ways on both sides to approach each other, so that the corresponding inclined surfaces contact the edges of the side wall fixings and the iron plate respectively, and the inclined surfaces cooperate with the bottom surfaces of the supporting blocks to achieve auxiliary support for the side wall fixings and the iron plate at different distances, thereby strengthening the supporting force of the entire fixed structure.

[0010] It is further defined that the fixing hole is a waist-shaped hole, and such a design enhances installation adaptability.

[0011] It is further defined that the jaw clamp is matched with a gasket. Such a design expands the contact area, strengthens the installation locking strength, and is not easy to damage the contact surface.

[0012] It is further defined that the iron plate is provided with a waist-shaped matching hole. Such a design enables the jaws clamp to be installed inside the iron plate, and the iron plate in turn can limit the jaws clamp.

[0013] The beneficial effects of adopting the utility model are:

[0014] By adopting the structural design of the utility model, the gravity of the top side wall shielding steel plate is transferred to the ring beam, that is, the weight of the side wall shielding steel plate is dispersed, so that the overall weight of the side wall shielding steel plate is lighter than that of the bottom steel plate, effectively preventing the bottom steel plate from being deformed by gravity, and ensuring the service life;

[0015] The structure of the utility model is applicable to the distances between different steel structures and side wall steel plates, and has a relatively large adjustable range. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 to Figure 4 As shown, a side wall shielding steel plate fixing structure of a large darkroom of the utility model comprises a ring beam 1 and a side wall steel plate 2 used in the construction of the darkroom, the side wall steel plate 2 is screwed with a side wall fixing member 3, the side wall fixing member 3 is vertically installed on the side wall steel plate 2, the side wall fixing member 3 is parallel to the upper horizontal plane of the ring beam 1, the side wall fixing member 3 is provided with four fixing holes 4, the four fixing holes 4 are all provided with locking screws 5, and the locking screws 5 are threadedly connected with fastening nuts 6 on both upper and lower sides of the fixing holes 4;

[0026] The ring beam 1 is symmetrically provided with jaw clamps 7 on both sides thereof, and an iron plate 8 is installed on the ring beam 1 through the jaw clamps 7 . The iron plate 8 is provided with countersunk holes 9 , and locking screws 5 are located in the countersunk holes 9 .

[0027] In this embodiment, when a side wall shielding steel plate fixing structure of a large darkroom is used, the side wall fixing member 3 is vertically installed on the side wall steel plate 2 by screws. The screws are preferably M10 screws with good load bearing and ensure the connection strength. Then, the nut end of the locking screw 5 is placed in the countersunk hole 9 of the iron plate 8, and the threaded end of the locking screw 5 is passed through the fixing hole 4. Then, the iron plate 8 is fixed to the ring beam 1 by the jaw clamp 7, and then the fastening nut 6 on the locking screw 5 is rotated so that the two fastening nuts 6 are pressed tightly against the side wall fixing member 3.

[0028] In summary, the weight of the side wall steel plate 2 is dispersed on the ring beam 1, and the ring beam 1 does not contact the bottom steel plate, so it will not affect the bottom steel plate. The side wall steel plate 2 with dispersed weight is not easy to deform the bottom steel plate, thus ensuring the overall verticality.

[0029] Preferably, a reinforced supporting structure 10 is installed between the side wall fixing 3 and the iron plate 8; the reinforced supporting structure 10 includes two fork rows 101, and the ends of the fork rows 101 are integrally connected with supporting blocks 102, and the supporting blocks 102 are provided with inclined surfaces 103.

The threads of the pull tubes 105 are opposite to those of the threaded connection of the two capped screws 104, and the outer side of the pull tubes 105 is integrally connected with hexagonal screw caps 106. Such a design, by locking the pull tubes 105, allows the supporting blocks 102 installed in opposite ways on both sides to approach each other, so that the corresponding inclined surfaces 103 contact the edges of the side wall fixings 3 and the iron plate 8 respectively, and the inclined surfaces 103 cooperate with the bottom surfaces of the supporting blocks 102 to achieve auxiliary support for the side wall fixings 3 and the iron plate 8 at different distances, thereby strengthening the supporting force of the entire fixed structure.

[0030] Preferably, the fixing hole 4 is a waist-shaped hole. Such a design enhances installation adaptability. In fact, the structural style of the fixing hole 4 can also be considered according to specific circumstances.

[0031] Preferably, the jaw clamp 7 is matched with a gasket 11. Such a design can expand the contact area, strengthen the installation locking strength, and not easily damage the contact surface. In fact, the thickness of the gasket 11 can also be considered according to specific circumstances.
