Description

Technical Field

[0001] The present invention relates to the technical field of steel structure building components, in particular to a metal or non-metal insulation mechanism specifically used in steel structure building components, and in particular to an insulation mechanism used in steel structure buildings. Background Art

[0002] The skeleton or main structure of a steel structure building is assembled from a number of steel beams. After the assembly is completed, the corresponding insulation mechanism is filled in the skeleton. This type of insulation mechanism is installed in the steel structure through secondary installation and achieves good building sound insulation / insulation effects through its own non-metallic materials. For example, the prior art discloses a steel structure insulation exterior wall with publication number CN107975155A. It includes an I-beam, a floor slab, an exterior wall panel, an angle steel, a high-strength connecting bolt, an upper groove, a lower groove, a stiffening rib, a thermal bridge breaking strip, a trapezoidal groove, a trapezoidal groove double tongue, a trapezoidal pin head, and a trapezoidal pin head flat bayonet. The upper surface of the upper floor slab overlaps the upper flange of the upper I-beam, and the lower surface overlaps the horizontal surface of the angle steel. The upper groove is inserted into one side of the lower flange of the upper I-beam. The upper part of the exterior wall panel is tightly attached to the web of the upper I-beam. The horizontal surface of the angle steel is connected to the lower flange of the upper I-beam to form a connecting surface. The vertical surface is connected to the exterior wall panel to form a connecting surface. The high-strength connecting bolts anchor the connecting surface to the angle steel embedded in the exterior wall panel. The trapezoidal pin heads and trapezoidal grooves of the connecting surfaces of the exterior wall panels match each other. The invention has high bearing capacity, good integrity, effectively cuts off thermal bridges, is easy to construct, has a fast construction speed, has a simple connecting piece structure, a small number of connecting pieces, and can be factory-produced.

[0003] Another example is a heat-insulating fireproof steel structure with publication number CN108978902A, which includes a steel structure body, a heat-insulating layer, a fireproof board, an outer cavity, an inner cavity, a coolant, a water pipe, a water pump, a water source, a valve, and a film. A fireproof board is provided on the surface of the steel structure body, a heat-insulating layer is provided inside the steel structure body, an outer cavity is provided on one side of the steel structure body, a coolant is provided in the outer cavity, a channel is connected between the outer cavity and the heat-insulating layer, and the channel is sealed by a film. One side of the heat-insulating layer is an inner cavity, one side of the inner cavity is connected to a water pipe, a valve is provided on the water pipe, and the water pipe is connected to a water source through a water pump. The invention provides water and sodium chloride, and cools the steel structure by the endothermic effect of the hydrolysis reaction, effectively utilizing the inner cavity space of the steel structure, and at the same time has the advantages of convenient processing and simple structure.

[0004] According to the above-mentioned prior art, this type of insulation mechanism often has innovative designs from two aspects: connection method and insulation material. Insulation materials are conventionally made of non-metallic materials. In the case of no obvious progress in materials science, the effect of improving the connection method is far greater than the latter. However, in order to improve the applicability, this type of insulation mechanism may cause the connection points to be unable to fit the steel structure, which may easily make the wall structure formed by the steel structure loose or the outer surface uneven. At the same time, the insulation material itself is not tightly fitted to the inner decorative panel, resulting in a further decrease in the insulation performance. Summary of the invention

[0005] The object of the present invention is to provide an insulation mechanism for steel structure buildings, so as to solve the problem proposed in the above background technology that in order to improve the applicability, the connection points of such insulation mechanisms cannot fit the steel structure, which easily makes the wall structure formed by the steel structure loosely connected or the outer surface uneven, and at the same time, the insulation material itself is not tightly fitted with the inner decorative panel, resulting in a further decrease in the insulation performance.

[0006] To achieve the above object, the present invention provides the following technical solution: a heat preservation mechanism for a steel structure building, comprising a heat preservation mechanism frame for fitting and connecting with a steel beam and a heat preservation plate embedded in a through groove at the center of the heat preservation mechanism frame, wherein the heat preservation mechanism frame is a frame structure with a thickness difference, which is thin at the sides and thick at the center, and the thickness difference is used to match the beam structure of the steel building;

[0007] At the same time, a strip groove is provided on the inner surface of the heat preservation board, and the strip groove is arranged non-through at both ends of the heat preservation board.

[0008] As a further feature, a buffer plate is horizontally elastically slidably connected to the thin-wall inner edge of the frame of the thermal insulation mechanism. The buffer plate fits the steel beam from the outer vertical surface of the steel beam and is used to alleviate the impact force between the thermal insulation mechanism and the steel beam.

[0009] Furthermore, a through hole is opened at the thick wall outer edge of the insulation mechanism frame, and the through hole coincides with the magnetic block hidden in the inner wall of the insulation mechanism frame in the initial state, wherein the magnetic block is used to pop out from the inside of the insulation mechanism frame after the buffer plate is squeezed and contacts the steel beam, and passes through the through hole to be adsorbed and adhered to the steel beam.

[0010] Furthermore, the rod structure on the back of the buffer plate extends through the side wall of the insulation mechanism frame to the internal space of the insulation mechanism frame, and a first traction plate with an obtuse angle is arranged in the internal space, and a second traction plate is attached to the inner surface of the bottom bent surface of the first traction plate, and the two traction plates are respectively rotatably installed in the insulation mechanism frame around their own pin shafts, and the left end of the second traction plate is attached to the upper surface of the bottom plate.

[0011] As a further feature, the bottom plate is installed vertically slidingly inside the frame of the insulation mechanism through a sliding rod, and the upper end surface of the bottom plate is used to install the magnetic block, and the left end of the second traction plate is used to make the bottom plate in the initial state and the spring on the sliding rod in a compressed state.

[0012] As a further feature, the right side angle formed by the left section plate structure of the second traction plate and the bottom plate is an acute angle.

[0013] As a further feature, a disassembly plate is provided above the base plate and is fixed to the inner end of the operating shaft. The operating shaft is rotatably installed through the frame of the heat preservation mechanism and the outer end of the operating shaft is used to connect to the operating tool and rotate the disassembly plate synchronously.

[0014] Furthermore, a magnetic sheet is connected to the bottom end of the slide rod in the middle position of the same row or column. The magnetic sheet and the slide rod are slidably installed inside a first cylinder fixed in the frame of the insulation mechanism. After the insulation board is installed, the cylinder is distributed corresponding to the second cylinder installed at the edge of the insulation board.

[0015] As a further feature, a magnetic sheet installed at the outer end of the vertical rod is also disposed in the second cylinder, and the magnetic sheet and the magnetic sheet 17 in the first cylinder are disposed opposite to each other and attract each other.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the insulation mechanism for steel structure buildings redesigns the connection mode between the insulation mechanism frame and the steel beam and between the insulation mechanism frame and the insulation board, so that the insulation mechanism frame serves as a connection mechanism between the insulation mechanism as a whole and the steel beam, which can achieve better buffering, connection and convenient disassembly effects, and can solve the problems of component aging and possible insufficient connection strength caused by long-term placement, and can stably disassemble and assemble the insulation board itself, while improving the board surface structure of the insulation board, ensuring connection stability and ensuring insulation effect, as shown in the following content:

[0017] 1. The structural design of the strip groove on the inner surface of the insulation board can improve the connection stability by increasing the contact area between the surface and the inner wall finishing material of the steel building. At the same time, the strip groove is designed to be non-through, so when the insulation board and the interior material are integrally fitted, the strip groove will form a relatively closed space, thereby ensuring the insulation effect;

[0018] 2. The use of magnetic blocks and multiple groups of traction plates enables the structural design of the buffer plate to not only protect the insulation mechanism during the docking process with the steel beam, but also enable the traction magnetic blocks to pop out from the inside of the insulation mechanism frame to complete the positioning connection when the buffer plate moves to the maximum distance under the rotation and traction of the traction plate. In addition, the travel limit of the buffer plate can be shortened, that is, the outer surface of the magnetic pop-up buffer plate will not be completely in contact with the insulation mechanism frame, which can also facilitate the addition of reinforcement materials such as adhesives, making assembly more convenient and efficient.

[0019] Furthermore, the unique angle design between the traction plate and the bottom plate enables the bottom plate and the slide bar to be compressed a certain distance before popping out, thereby providing a greater initial rebound force, thereby preventing the elastic member from affecting the rebound of the magnetic block due to long-term storage;

[0020] Furthermore, the structural design of multiple sets of magnetic plates and vertical rods can produce a traction effect when the sliding rod moves downward, drive the vertical rods to move together and produce a snap-fit ​​effect between the insulation plate and the frame of the insulation mechanism. The operation is very convenient and facilitates the subsequent separate disassembly and replacement of the insulation plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 11 , the present invention provides the following technical solutions:

[0035] Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, the following solution is disclosed, which can be referred to Figure 1-Figure 2 , including a heat preservation mechanism frame 1 for fitting and connecting with the steel beam and a heat preservation board 2 embedded in the through groove at the center of the heat preservation mechanism frame 1. The heat preservation mechanism frame 1 is a frame structure with a thickness difference that is thin on the sides and thick in the center. The thickness difference is used to match the beam structure of the steel building; at the same time, a strip groove 3 is opened on the inner surface of the heat preservation board 2. The strip groove 3 is non-through at both ends of the heat preservation board 2. In order to reduce the space occupied by the heat preservation mechanism in the steel structure building, especially between the two steel beams, and to avoid excessive coverage of the beam structure by the heat preservation part, the entire heat preservation mechanism is designed to It has two parts. One part is the insulation mechanism frame 1 which is used to adhere to the steel structure for a long time and maintain the flat wall facade. The middle part of the insulation mechanism frame 1 is hollowed out, and the hollowed-out part is used to accommodate the insulation board 2. At the same time, the inner surface of some steel structure walls will use aluminum plates or plastic steel plates and other materials to cover the insulation material for the second time. In order to ensure the connection stability between the insulation material and the inner layer material, an array of strip grooves 3 are set on the inner surface of the insulation board 2. In this way, the connection stability between the insulation board 2 and the inner layer covering material is increased.

[0036] The crisscross steel beams form a plurality of hole structures, which are used to place the heat preservation mechanism. The heat preservation mechanism at the lower part can be realized by manual assembly of the construction workers, while the heat preservation mechanism at the higher part needs to be assisted by hoisting equipment. However, the hoisting point itself is not completely stable, and it is easy to cause excessive collision between the heat preservation mechanism and the steel beam during the docking process due to shaking. Therefore, in order to solve this problem, the present embodiment discloses Figure 2 and Figure 3 In the scheme shown, a buffer plate 4 is horizontally elastically slidably connected at the thin-wall inner edge of the frame 1 of the heat preservation mechanism, and the buffer plate 4 fits the steel beam from the outer vertical surface of the steel beam and is used to alleviate the impact force between the heat preservation mechanism and the steel beam. A through hole 5 is opened at the thick-wall outer edge of the frame 1 of the heat preservation mechanism, and the through hole 5 is consistent with the magnetic block 6 hidden in the inner wall of the frame 1 of the heat preservation mechanism in the initial state, wherein the magnetic block 6 is used for the buffer plate 4 to pop out from the inside of the frame 1 of the heat preservation mechanism after squeezing and contacting the steel beam, and pass through the through hole 5 to be adsorbed and fit with the steel beam, wherein the buffer plate 4 is elastically slidably installed on the surface of the narrow wall inner edge of the frame 1 of the heat preservation mechanism, that is, close to the steel beam. As the name suggests, the buffer plate 4 utilizes its own elastic sliding setting on the insulation mechanism frame 1 to buffer the impact force generated when the insulation mechanism frame 1 is connected to the steel beam. At the same time, in order to ensure the stability of the connection between the insulation mechanism frame 1 and the steel structure, as well as to position it in advance and avoid positional errors during operations such as drilling and bolting, a magnetic attraction structure is also provided. Specifically, during the process of the buffer plate 4 being connected to the steel beam and being gradually squeezed, the magnetic block 6 will pop out accordingly and realize stable adsorption of the insulation mechanism frame 1 and the steel beam, so that the insulation mechanism frame 1 and the steel beam can be stably pre-positioned.

[0037] The solution disclosed in this embodiment is a further elaboration of the above solution, and also achieves additional technical effects. For details, please refer to Figure 4-Figure 7 The rod structure on the back of the buffer plate 4 passes through the side wall of the insulation mechanism frame 1 and extends into the internal space of the insulation mechanism frame 1, and a first traction plate 7 with an obtuse angle is arranged in the internal space, and a second traction plate 8 is attached to the inner surface of the bottom bending of the first traction plate 7, and the two traction plates are respectively rotatably installed in the insulation mechanism frame 1 around their own pin shafts 9, and the left end of the second traction plate 8 is attached to the upper surface of the bottom plate 10, and the bottom plate 10 is vertically slidably installed inside the insulation mechanism frame 1 through the sliding rod 11, and the upper end surface of the bottom plate 10 is used to install the magnetic block 6, and the left end of the second traction plate 8 is used to make the bottom plate 10 in the initial state and the spring on the sliding rod 11 in a compressed state, and the right side angle formed by the left section plate structure of the second traction plate 8 and the bottom plate 10 is an acute angle.

[0038] When the buffer plate 4 is squeezed and moved by the steel beam, the rod structure on the inner wall of the buffer plate will also press against the top of the first traction plate 7, so that the traction plate rotates around the pin shaft 9 at the center of its rotation circle, so the bottom end of the traction plate will be rotated and lifted obliquely upward, and at this time, the right end of the second traction plate 8 will be correspondingly lifted by sliding on the inner surface of the first traction plate 7, and the second traction plate 8 rotates around the pin shaft 9 at the center of its rotation circle, so the left end of the second traction plate 8 will be free from the limit of the bottom plate 10 after rotating to a certain angle, and the bottom plate 10 will bounce upward and drive the magnetic block 6 to pass through the through hole 5 and fit at the lower edge or side edge of the steel beam. The specific position depends on the installation direction of the heat preservation mechanism;

[0039] At the same time, due to different steel structure buildings, the distribution spacing of steel beams and the size of steel beams are different, and the corresponding specifications and parameters of the insulation mechanism are also different. The construction company will customize the steel beams and the insulation mechanism at the same time after confirming the parameters of the steel beam construction drawing. However, the reality is that after the insulation mechanism is processed, it is necessary to wait until the steel beams are assembled before installing the insulation mechanism. During this process, the elastic parts in the insulation mechanism are prone to aging and the rebound effect is reduced. Therefore, in order to avoid this problem, the present embodiment also discloses the following scheme, that is, the right side angle formed by the left section plate structure of the second traction plate 8 and the bottom plate 10 is an acute angle. During the rotation of the second traction plate 8, the bottom plate 10 will first be pressed downward for a distance. During this process, the spring on the slide rod 11 is compressed and generates a larger rebound force. Therefore, even if the elastic parts are aged due to being left for too long, the magnetic block 6 will not be unable to rebound, thereby ensuring the stability of the connection between the insulation plate as a whole and the steel structure.

[0040] Embodiment 2: The solution disclosed in this embodiment is mainly to dismantle the frame 1 of the insulation mechanism. When some temporary steel structures or insulation mechanisms are dismantled for recycling or replacement, multiple sets of magnets adsorbed on the steel beams will increase the difficulty of dismantling the insulation mechanism. It is also a further supplement to the above solution. Please refer to Fig. 9 As shown, a disassembly plate 12 is also provided above the bottom plate 10, and the disassembly plate 12 is fixed to the inner end of the operating shaft 13. The operating shaft 13 is rotatably installed through the frame 1 of the heat preservation mechanism, and the outer end of the operating shaft 13 is used to be connected with the operating tool and to rotate the disassembly plate 12 synchronously. When the heat preservation mechanism needs to be disassembled as a whole, the operating shaft 13 can be driven to rotate the disassembly plate 12 through the outer polygonal or inner polygonal structure of the exposed section of the operating shaft 13. In this way, the magnetic blocks 6 are separated from the steel beams one by one, which facilitates the subsequent disassembly of the heat preservation mechanism as a whole. In addition, the operating shaft 13 can maintain the rotated state through damping, or adopt an existing mature rotation locking scheme. This is the prior art and will not be further described.

[0041] The solution disclosed in this embodiment is how to use the disassembly and installation structure of the above-mentioned insulation mechanism frame 1 to conveniently disassemble and install the insulation board 2, such as Figure 9-11 As shown, the bottom end of the slide bar 11 in the middle position of the same row or column is also connected to a magnetic piece 17, and the magnetic piece 17 and the slide bar 11 are slidably installed in the first cylinder 14 fixed in the insulation mechanism frame 1. After the insulation board 2 is installed, the cylinder is distributed corresponding to the second cylinder 15 installed at the edge of the insulation board 2. The second cylinder 15 is also provided with a magnetic piece 17 installed at the outer end of the vertical rod 16. The magnetic piece 17 and the magnetic piece 17 in the first cylinder 14 are arranged to be opposite to each other. First, the insulation board 2 and the insulation mechanism frame 1 are assembled, and during the installation process of the insulation mechanism frame 1, due to the position of the insulation board 2, the second cylinder 15 is provided with a magnetic piece 17 installed at the outer end of the vertical rod 16. The slide bar 11 in the middle position will first move downward and then move upward, so the magnetic piece 17 at the bottom end of the slide bar 11 in this position will enter the second cylinder 15 and adsorb the magnetic piece 17 on the vertical rod 16. After the slide bar 11 moves upward, it will pull the vertical rod 16 to synchronously enter the first cylinder 14, completing the reinforced docking of the insulation board 2 and the insulation mechanism frame 1. When disassembling and replacing the insulation board 2, only the disassembly plate 12 in the middle position is rotated and the contact surfaces of the two magnetic pieces 17 are moved to the fitting surface of the insulation board 2 and the inner wall of the insulation mechanism frame 1, so that the insulation board 2 can be pushed out horizontally, and then the subsequent new insulation board 2 can be installed.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
