[0001] The present invention relates to the technical field of steel structure buildings, and in particular to an assembled steel structure building component and an assembled building. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled on site using prefabricated components. The advantages of this type of building are fast construction speed, little restriction by climatic conditions, labor saving and improved building quality. However, since prefabricated buildings do not use concrete casting and only use detachable connectors, their structural stability is poor and their ability to resist natural disasters is poor. At the same time, the thermal insulation capacity of this type of prefabricated building is also poor. Therefore, a technical solution is disclosed in Patent No.: CN201710654822.5. This technical solution solves the above-mentioned problems of poor thermal insulation capacity of buildings and poor ability to prevent natural disasters. However, this technical solution still has some problems when used. When splicing, this technical solution is achieved by placing prefabricated panels inside I-beams. , and then spliced ​​with bolts and connecting steel parts. However, in actual use, since the prefabricated parts are inserted into the I-beam, the upper side of the I-beam and the surface of the prefabricated parts cannot be in the same plane, which leads to the equipment assembly being not flat enough, thus affecting the subsequent use of the equipment. Patent No.: CN202110503002.2 also discloses a technical solution. When using this technical solution, it is necessary to align the bolt holes of each connecting part and then tighten the bolts.

When the equipment is assembled, even if the bolts are detached, the steel plate can always press down the fixing mechanism by its own gravity to keep the equipment connected. The placement and fixation of the steel plate increases the connection strength between the prefabricated plate and the edge steel, and fills the depression between the edge steel and the I-beam to form a plane, thereby avoiding the equipment from being affected by the uneven surface and affecting the later use of the equipment. When the equipment is disassembled, only the steel plate needs to be detached to detach the fixing mechanism and the edge steel, thereby completing the disassembly. The coordination of parts in the equipment makes the equipment more stable when fixed and faster when disassembled.

[0015] After the edge steel, prefabricated panel and steel plate are fitted and fixed, the self-locking mechanism and the connecting steel mechanism cooperate with each other to ensure that the connecting steel structure is always in a pulled-out state when the equipment is fitted and fixed, so as to ensure the connection stability of the three and avoid the connection steel mechanism from falling off during connection, which would result in the equipment not being fully fixed, further improving the stability and convenience of the equipment.

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.

[0026] See also Figure 1-Figure 6 The present invention provides a technical solution: an assembled steel structure building component and an assembled building, comprising two edge steels 1, both of which have openings on the inner sides thereof.

[0027] A plurality of fixing holes 2 are provided, two pairs of slots 3 are provided on the upper and lower sides of the edge steel 1, a prefabricated plate 5 is movably connected between the two edge steels 1, a plurality of pairs of cavities 6 are provided in the prefabricated plate 5, a fixing mechanism 7 is provided in the cavity 6, two steel plates 16 are movably connected between the two edge steels 1, the steel plate 16 and the fixing mechanism 7 are movably connected, the two steel plates 16 are respectively located on both sides of the prefabricated plate 5, four blocks 17 are provided on the steel plate 16, the blocks 17 are movably connected in the slots 3, a self-locking mechanism 18 is provided on the blocks 17, plug interfaces 21 are provided on the edge steel 1, the prefabricated plate 5 and the steel plate 16, a connecting steel mechanism 22 is movably connected between the three plug interfaces 21;

[0028] During operation, the edge steel 1 is placed at a suitable position, and then the prefabricated panel 5 is inserted between the two edge steels 1. When the prefabricated panel 5 is inserted at a suitable position, the block 17 set on the steel plate 16 is inserted into the slot 3, and then the steel plate 16 is pressed downward. When the steel plate 16 is subjected to force and under the action of its own gravity, the steel plate 16 squeezes the fixing mechanism 7, so that the parts in the fixing mechanism 7 are opened, so that the fixing mechanism 7 and the fixing hole 2 are matched, and when the steel plate 16 is placed, the self-locking mechanism 18 set on the steel plate 16 slides in the slot 3, so that the steel plate 16 is clamped in the slot 3 on the edge steel 1. After the steel plate 16 is placed, the connecting steel mechanism 22 is used to lock the two steel plates 16 and the prefabricated panel 5, and then the bolts 26 are used to lock the steel plate 16 and the prefabricated panel 5 for a second time, and the equipment splicing is completed;

[0029] The present invention makes the equipment more stable during assembly through the cooperation of the edge steel 1, the prefabricated plate 5 and the steel plate 16. When a prefabricated plate 5 is assembled in two edge steels 1, the prefabricated plate 5 is slidably connected between the two edge steels 1, so that the prefabricated plate 5 and the two are more stable when connected, avoiding the need to use the bolt 26 holes for alignment and fixing, thereby accelerating the fixing efficiency of the equipment. After the edge steel 1 and the prefabricated plate 5 are assembled, the steel plate 16 is clamped to the inner sides of the two edge steels 1 through the cooperation of the clamping block 17 and the clamping groove 3. At the same time, the gravity of the steel plate 16 itself presses down the fixing mechanism 7 to open the fixing mechanism 7. When the fixing mechanism 7 is opened, the parts in the fixing mechanism 7 are inserted into the fixing holes 2 of the edge steel 1, so that the prefabricated plate 5 and the edge steel 1 are fixed more quickly and stably. Subsequently, the steel plate 16 is fixed for the second time by the bolts 26 to ensure the close fit between the steel plate 16 and the prefabricated plate 5. When the equipment is assembled, even if the bolts 26 are detached, the steel plate 16 can The fixing mechanism 7 is always pressed down by its own gravity to keep the equipment connected, and the placement and fixation of the steel plate 16 increases the connection strength between the prefabricated panel 5 and the edge steel 1, and fills the depression between the edge steel 1 and the I-beam to form a plane, thereby avoiding the equipment being affected by the uneven surface and affecting the later use of the equipment. When the equipment is disassembled, it only needs to detach the steel plate 16 to detach the fixing mechanism 7 and the edge steel 1, thereby completing the disassembly. The coordination of parts in the equipment makes the equipment more stable when fixed and faster when disassembled. After the edge steel 1, the prefabricated panel 5 and the steel plate 16 are fitted and fixed, the self-locking mechanism 18 and the connecting steel mechanism 22 cooperate with each other, so that when the equipment is fitted and fixed, the connecting steel structure is always in a pulled-out state, so as to ensure the connection stability of the three, avoid the connection steel mechanism 22 from falling off during connection, thereby causing the equipment to be unable to be fully fixed, and further improve the stability and convenience of the equipment.

[0030] As a further solution of the present invention, the edge steel 1 is an I-beam, the prefabricated plate 5 is in an inverted I-shape, and four bolts 26 are threadedly connected between the prefabricated plate 5 and the steel plate 16, and the four bolts 26 are located at the four corners of the steel plate 16; when working, after the steel plate 16 and the prefabricated plate 5 are installed, the four bolts 26 are used to fasten the prefabricated plate 5 and the steel plate 16.

[0031] The device is reinforced to ensure the connection stability of the device, avoid the device from falling off during use, and further improve the stability of the device.

[0032] As a further solution of the present invention, the fixing mechanism 7 includes a pressure rod 8, a first spring 9, a first force block 10, a push rod 11, a second spring 12, a fixing rod 13, a third spring 14 and a second force block 15. The pressure rod 8 is slidably connected in the cavity 6, the pressure rod 8 is sleeved with the first spring 9, the bottom surface of the pressure rod 8 is installed with the first force block 10, two push rods 11 are slidably connected in the cavity 6, the push rod 11 and one side of the inner wall of the cavity 6 are fixedly connected with the second spring 12, two fixing rods 13 are slidably connected on the prefabricated plate 5, the fixing rod 13 is movably connected in the fixing hole 2, the two fixing rods 13 are respectively located on both sides of the two push rods 11, the fixing rod 13 is sleeved with the third spring 14, and the second force block 15 is installed at one end of the fixing rod 13;

[0033] During operation, when the prefabricated panel 5 moves to a suitable position, the steel plate 16 is placed on the upper side of the prefabricated panel 5. At this time, the gravity of the steel plate 16 itself and the external pressure cause the steel plate 16 to descend, thereby causing the steel plate 16 to squeeze the pressure rod 8 in the fixing mechanism 7. When the pressure rod 8 is subjected to force, the pressure rod 8 descends, thereby causing the first force block 10 to squeeze the push rod 11 to both sides. When the push rod 11 is subjected to force, the push rod 11 pushes the two second force blocks 15, causing the second force blocks 15 to push the fixing rod 13 upward. When the fixing rod 13 moves upward, the fixing rod 13 is inserted into the fixing hole 2 to ensure the connection stability between the prefabricated panel 5, the steel plate 16 and the edge steel 1, avoiding the need to use multiple bolts 26 for fixing the equipment, and further accelerating the assembly efficiency of the equipment.

[0034] As a further solution of the present invention, one end of the first spring 9 is fixedly connected to the pressure rod 8, and the other end is fixedly connected to the prefabricated plate 5. One end of the third spring 14 is fixedly connected to one side of the inner wall of the cavity 6, and the other end is fixedly connected to the fixing rod 13. During operation, when the pressure rod 8 is subjected to pressure, the pressure rod 8 pulls the first spring 9, so that the first spring 9 is stretched under force. At this time, the first force block 10 moves downward, thereby squeezing the push rod 11 to both sides. When the push rod 11 and the second force block 15 contact, the second force block 15 squeezes the fixing rod 13, and at the same time compresses the second spring 12, and then moves the fixing rod 13 up to a suitable position. When the equipment is disassembled, it is only necessary to remove the steel plate 16. Even if the first spring 9 and the second spring 12 are reset, the fixing rod 13 and the fixing hole 2 can be disengaged, thereby taking out the prefabricated plate 5, so as to achieve the purpose of improving the efficiency of the equipment during installation and disassembly.

[0035] As a further solution of the present invention, the first force block 10 and the second force block 15 are both wedge-shaped, one end of the push rod 11 is wedge-shaped, the lateral length of the push rod 11 is inclined, the second force block 15 is movably connected to the upper side of the push rod 11, and the first force block 10 is movably connected between the two push rods 11; during operation, when the first force block 10 squeezes the two push rods 11, since the first force block 10 is wedge-shaped, when the first force block 10 is rammed and descends, the first force block 10 will gradually squeeze the two push rods 11 to separate them, and since the push rod 11 is inclined, as the push rod 11 moves, the push rod 11 will continue to squeeze the second force block 15 to move the second force block 15 upward to ensure that the fixing rod 13 can be inserted into the fixing hole 2, thereby improving the installation stability of the equipment and the efficiency of installation and disassembly.

[0036] As a further solution of the present invention, the self-locking mechanism 18 includes a lock slot 4, a fourth spring 19 and a self-locking block 20. The lock slot 4 is provided in the card slot 3, the fourth spring 19 is fixedly connected in the card block 17, the self-locking block 20 is installed at one end of the fourth spring 19, the self-locking block 20 is movably connected in the lock slot 4, a track slot is provided on the upper side of the lock slot 4, and the lock slot 4 and the track slot are connected; when working, when the steel plate 16 is installed, the card block 17 set on the steel plate 16 is placed in the card slot 3, and then pressed down, at this time the self-locking block 20 slides in the track slot, this The fourth spring 19 is in a compressed state, and as the steel plate 16 continues to descend, the self-locking block 20 continues to move downward until the self-locking block 20 moves into the locking groove 4. At this time, the elastic force of the fourth spring 19 acts on the self-locking block 20, so that the self-locking block 20 is locked in the locking groove 4, thereby fixing the steel plate 16. When the bolts 26 and the connecting steel mechanism 22 in the equipment are separated from the steel plate 16, the gravity of the steel plate 16 itself cooperates with the self-locking mechanism 18 to still keep the fixing mechanism 7 open, thereby further improving the installation stability of the equipment.

[0037] As a further solution of the present invention, the connecting steel mechanism 22 includes a first plug-in board 23, a second plug-in board 24 and a locking column 25, wherein the first plug-in board 23 is movably connected in the two plug-in ports 21, the first plug-in board 23 is Z-shaped, and the second plug-in board 24 is movably connected in the other plug-in port 21, and a locking column 25 is provided between the first plug-in board 23 and the second plug-in board 24, the second plug-in board 24 is rotatably connected to the locking column 25, and the first plug-in board 23 is threadedly connected to the locking column 25, and the locking The threads on the upper and lower sides of the column 25 are in opposite directions; during operation, after the prefabricated panel 5, the steel plate 16 and the edge steel 1 are fixed, the first plug-in board 23 and the second plug-in board 24 are respectively plugged into the plug-in port 21. At this time, the first plug-in board 23 and the second plug-in board 24 are fixed in the plug-in port 21 by another self-locking mechanism 18, and then the locking column 25 is rotated to bring the two first plug-in boards 23 closer to each other, and then bring the two steel plates 16 and the prefabricated panel 5 closer, thereby ensuring the stability of the equipment during installation.
