Description

Technical Field

[0001] The utility model relates to the technical field of elevator shafts, in particular to an elevator steel structure shaft connected by H-shaped steel bolts. Background Technique

[0002] The elevator shaft made of steel structure is a common structural design, usually used to support and protect the operation of the elevator system. At the same time, in order to be able to bear large loads and pressures and ensure the stability and safety of the structure, it is usually made of high-strength H-shaped steel. Its shape design makes it have superior performance when bearing vertical and horizontal forces. At the same time, in order to fix the overall position of the steel structure shaft and keep it stable during the operation of the elevator, embedded parts need to be set during concrete pouring. After connecting with the steel structure shaft, the position of the steel structure shaft is fixed to ensure the stability during the operation of the elevator.

[0003] The position of the embedded parts is fixed after the concrete solidifies and cannot be adjusted. When the steel structure shaft is connected to the embedded parts, it may be difficult to connect the steel structure shaft to the embedded parts due to large deviations in the position of the embedded parts during setting, or there may be gaps after connection, which cannot play a good fixing role for the steel structure shaft, affecting the stability and safety of the structure. At the same time, the elevator car or guide rail system inside the steel structure shaft may shake and make noises due to unstable structure, increasing the risk of accidents. In view of this, the utility model proposes an elevator steel structure shaft connected by H-shaped steel bolts. Content of the Utility Model

[0031] Embodiment

[0032] Such as Figure 1 And Figure 2As shown in the figure, a steel structure hoistway for an elevator with H-shaped steel bolts proposed by the present utility model includes a steel structure body 1. The steel structure body 1 includes columns 11, cross beams 12, support columns 13, and a bottom plate 14. The columns 11, cross beams 12, and support columns 13 are all made of H-shaped steel, and their shape design enables them to have superior performance when bearing vertical and horizontal forces. The four groups of columns 11 are each composed of multiple groups of vertical H-shaped steels connected by bolts for lengthening the length. The four groups of bottom plates 14 are respectively fixedly installed at the bottoms of the four groups of columns 11 to facilitate fixing the position of the steel structure body 1. A group of horizontally arranged cross beams 12 are connected between adjacent two groups of columns 11 by bolts. There are four groups of cross beams 12 arranged at the same height. The cross beams 12 are used to fix the positions between the columns 11. At the same time, diagonal beams can be arranged between the cross beams 12 to enhance the strength and make the structure stable. At the same time, eight groups of cross beams 12 are arranged corresponding to the same floor, that is, four groups are located above the preset elevator door and four groups are located below. The support columns 13 are arranged on both sides of the preset elevator door position. The support columns 13 are fixedly connected between two groups of cross beams 12 by bolts to strengthen the structure and facilitate the installation of the elevator door.

[0033] Furthermore, the above-mentioned steel structure hoistway includes a positioning component 2 buried in the ground for fixing the position of the steel structure body 1. The positioning component 2 includes a fixing block 21, embedded bars 22, first adjusting screws 23, and extrusion blocks 24. The fixing block 21 is arranged at the bottom of the bottom plate 14 and is a rectangular box body with an open top. The tops of multiple groups of embedded bars 22 buried in the ground are fixedly connected to the fixing block 21. After the concrete solidifies, the fixing block 21 is fixed in position through the embedded bars 22. Multiple groups of first adjusting screws 23 are slidably connected in the fixing block 21. At least two groups of first adjusting screws 23 are respectively arranged on the four side surfaces of the fixing block 21. The extrusion blocks 24 are rotatably connected to one end of the first adjusting screws 23 close to the bottom plate 14. The four groups of extrusion blocks 24 are respectively parallel to the four side surfaces of the fixing block 21. The bottom plate 14 is also rectangularly arranged. The four groups of extrusion blocks 24 respectively contact the four side surfaces of the bottom plate 14. When the first adjusting screws 23 move, they drive the extrusion blocks 24 to move, so that the extrusion blocks 24 approach the bottom plate 14 and squeeze the bottom plate 14 to fix the position of the bottom plate 14. The positioning component 2 also includes first adjusting nuts 25 and second adjusting nuts 26. Each group of first adjusting screws 23 is threadedly connected with a first adjusting nut 25, and the first adjusting nuts 25 are all arranged inside the fixing block 21. Each group of first adjusting screws 23 is also threadedly connected with a second adjusting nut 26 arranged outside the fixing block 21. The first adjusting nuts 25 and the second adjusting nuts 26 are all in contact with the second adjusting nuts 26. When the first adjusting nuts 25 rotate, they contact the fixing block 21, and the first adjusting screws 23 move along their own length directions, so that the extrusion blocks 24 approach and squeeze the bottom plate 14. The second adjusting nuts 26 are used to fix the positions of the first adjusting screws 23.

[0034] Further, please refer to Figures 3 - 5 The above-mentioned steel structure hoistway further includes multiple groups of support components 3 installed on each group of cross beams 12 for extruding the well wall to further fix the position of the steel structure body 1. The support component 3 includes a sliding hole 31, a fixing plate 32, a first through hole 33, a connection hole 34, and a threaded sleeve 35. The sliding hole 31 is opened at the middle position of the cross beam 12. A fixing plate 32 is slidably connected in the sliding hole 31. Multiple groups of first through holes 33 are opened on the fixing plate 32. A second through hole is also opened on the cross beam 12. Bolts pass through the first through holes 33 and the second through hole to fix the fixing plate 32 on the cross beam 12, so that the position of the fixing plate 32 is fixed. Multiple groups of connection holes 34 are also opened on the fixing plate 32. The multiple groups of connection holes 34 are symmetrically arranged on both sides of the cross beam 12. A group of threaded sleeves 35 are inserted through each group of connection holes 34. After entering the connection holes 34, the threaded sleeves 35 are connected to the fixing plate 32 as a whole by welding. The support component 3 further includes a second adjusting screw 36, a fixing column 37, a push plate 38, and a positioning ring 39. A group of second adjusting screws 36 are threadedly connected in each group of threaded sleeves 35. When the second adjusting screw 36 rotates, it moves along its own length direction. A fixing column 37 is provided at one end of the second adjusting screw 36 close to the well wall. The push plate 38 is arranged between the multiple groups of second adjusting screws 36 and the well wall. When the second adjusting screw 36 moves, it drives the push plate 38 to approach the well wall and extrude. Multiple groups of positioning rings 39 corresponding to the fixing columns 37 are installed on the side surface of the push plate 38. After the fixing column 37 enters the positioning ring 39, rotating the second adjusting screw 36 drives the push plate 38 to approach the well wall, and at the same time prevents the second adjusting screw 36 from sliding on the surface of the push plate 38 and affecting the fixing effect, and supports the cross beam 12 through the reaction force. Among the multiple groups of support components 3 corresponding to the above-mentioned preset elevator door positions, the second adjusting screw 36 is only provided on the side of the cross beam 12 away from the preset elevator door. At the same time, the areas of the fixing plate 32 and the push plate 38 are correspondingly reduced to prevent interfering with the setting of the elevator door.

[0035] In this embodiment, first, the embedded reinforcement bars 22 are embedded in the concrete layer. After the concrete solidifies, the position of the fixing block 21 is fixed. At this time, one end of an H-shaped steel is connected to the bottom plate 14 by bolts, and the bottom plate 14 is placed on the column 11. In this way, a set of H-shaped steel is arranged on each of the four groups of fixing blocks 21. At this time, the upper and lower cross beams 12 are connected by bolts between two adjacent groups of H-shaped steel, and at the same time, multiple inclined beams are also connected by bolts to strengthen the structure. At this time, the positions of multiple groups of H-shaped steel are fixed. Adjust the position of the bottom plate 14 to make the installation positions of multiple groups of H-shaped steel accurate, and ensure that the distance from the well wall is within a suitable range. At this time, by rotating the first adjusting nut 25, one side of the first adjusting nut 25 contacts the fixing block 21 when rotating. When the first adjusting nut 25 rotates, it drives the first adjusting screw 23 to move along its own length direction, so that the pressing block 24 contacts the bottom plate 14. The bottom plate 14 is pressed by the four groups of pressing blocks 24 to fix the position of the bottom plate 14. At this time, the positions of multiple groups of H-shaped steel are fixed. By connecting H-shaped steel above the vertical H-shaped steel by bolts in sequence, and installing the cross beam 12 and the support column 13 in sequence, the steel structure body 1 is formed. The volume of each group of H-shaped steel is small, which is convenient for installation.

[0036] After that, the fixing plate 32 is inserted into the sliding hole 31, and the position of the fixing plate 32 is fixed by bolts. Multiple groups of threaded sleeves 35 are inserted into the connection holes 34 and then welded and fixed. The second adjusting screw 36 is threadedly connected to the threaded sleeve 35. The push plate 38 is placed between the second adjusting screw 36 and the well wall, and at the same time, the positioning ring 39 on the side of the push plate 38 corresponds to the fixing columns 37 at one end of multiple groups of second adjusting screws 36. The fixing columns 37 are inserted into the positioning ring 39. Thus, when the second adjusting screw 36 rotates and moves at the same time, it drives the push plate 38 to approach and press the well wall, so that the position of the cross beam 12 is fixed by the reaction force, and the position of the steel structure body 1 is more stable.

[0037] The above specific embodiments are only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
