Description

Technical Field

[0001] The invention belongs to the field of mechanical and electrical engineering fixed brackets, and more specifically relates to an anti-seismic bracket. Background Art

[0002] The seismic bracket can not only fix the electromechanical engineering facilities, but also limit the large displacement of the electromechanical engineering facilities during earthquakes and control the vibration of the facilities. The seismic bracket can provide reliable protection for electromechanical engineering facilities during earthquakes and withstand the earthquake effects from the horizontal direction.

[0003] For example, a Chinese patent document with publication number CN112377714A discloses an anti-seismic support for building mechanical and electrical engineering, comprising a vertical connecting channel steel, a lateral connecting channel steel and a rear connecting channel steel, wherein an outer limiting bolt hole is provided at one end of the vertical connecting channel steel, an adjusting connecting rod is movably connected inside the vertical connecting channel steel, one end of the adjusting connecting rod is movably connected to an angle adjusting connecting plate, one end of the angle adjusting connecting plate is fixedly connected to a lateral connecting rod, the other end of the angle adjusting plate is fixedly connected to a rear connecting rod, an upper fixed clamping tube is fixedly connected below the adjusting connecting rod, fixing rod screw heads are provided at both ends of the upper fixed clamping tube, nuts are threadedly connected to the outer side of the fixing rod screw head, an intermediate fixing rod is fixedly connected below the fixing rod screw head, a lower fixed clamping tube is provided below the intermediate fixing rod, and rubber buffer pads are provided on the inner sides of the upper fixing splint and the lower fixing splint. The scheme provides an outer limiting bolt hole on the vertical connecting channel steel and an inner limiting bolt hole above the matching adjusting connecting rod. During installation, the adjusting connecting rod is moved and fixed by inserting fixing bolts into the outer limiting bolt hole and the inner limiting bolt hole to fix it. The height of the installation suspension can be easily adjusted to adapt to top installation structures of different shapes, and the installation of the lateral connecting channel steels and the rear connecting channel steels at both ends is convenient. By providing an angle adjustment connecting plate movably connected to the adjusting connecting rod, the angle adjustment connecting plate can conveniently adjust the rotation angle during installation, thereby adjusting the lateral connecting channel steel and the rear connecting channel steel fixedly connected to the angle adjustment connecting plate through the lateral connecting rod and the rear connecting rod, so as to facilitate the installation of the overall bracket in different installation environments. By providing an upper fixing splint and a lower fixing splint both of which have rubber buffer layers on the inner sides, during installation, whether it is a square ventilation duct or a cylindrical electromechanical duct, it can be firmly fixed between the upper fixing splint and the lower fixing splint through a thicker rubber buffer layer, so that it can be installed very conveniently.

[0004] The Chinese patent document with publication number CN109990160A discloses a multi-dimensional viscous damping tuned mass shock-absorbing bracket, including a load-bearing hanger, a transverse diagonal brace, a longitudinal diagonal brace, a horizontal load-bearing crossbar, a wire trough, a fixed angle steel and a tuning vibration-damping box, wherein the wire trough is used to accommodate pipelines, and a horizontal load-bearing crossbar is arranged at a certain distance at the lower part of the wire trough along the length direction, and the wire trough is fixedly connected to the horizontal load-bearing crossbar through the fixed angle steel, and the horizontal load-bearing crossbar is connected to the main structure through the load-bearing hanger, the transverse diagonal brace and the longitudinal diagonal brace to form a stable structure, and the wire trough ... Tuning vibration damping boxes are arranged inside it at regular intervals, and different tuning frequencies are adopted to absorb and vibrate energy in a wide band, and dissipate energy in multiple directions through viscous dampers; the load-bearing hangers, transverse diagonal braces, longitudinal diagonal braces and horizontal load-bearing crossbars adopt C-shaped channel steel or light steel pipe structure, and the transverse diagonal braces and longitudinal diagonal braces are arranged along the wire trough transversely and longitudinally respectively; one end of the load-bearing hangers, transverse diagonal braces and longitudinal diagonal braces is hinged to the horizontal load-bearing crossbar, and the other end is hinged to the main structure to form a stable spatial structure, providing installation space for the load-bearing wire trough and the tuning vibration damping box.

[0005] The common disadvantage of the above two schemes is that the vertical load-bearing hangers and diagonal braces directly connected to the main structure of the building are almost rigidly connected to the connection structure formed by the connection base used to install the electromechanical engineering facilities. When the electromechanical engineering facilities are deformed and displaced due to thermal expansion and contraction, the seismic support will prevent their deformation and displacement. When the degree of deformation and displacement is large, it may cause damage to the seismic support or the electromechanical engineering facilities. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an anti-seismic support which allows mechanical and electrical engineering facilities to deform or shift slowly while preventing them from shaking greatly during an earthquake.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: an earthquake-resistant support, including a vertical hanger, a connecting seat and a diagonal tie rod, the upper end of the vertical hanger is equipped with a first connecting structure of the building structure, the lower end of the vertical hanger is connected to the connecting seat, the connecting seat is equipped with a mechanical and electrical engineering facility installation structure, the diagonal tie rod includes a connecting tube 1, a ball hinge 1, a connecting tube 2, a ball hinge 2, a connecting plate 2 and a limit piece, one end of the connecting tube 1 is connected to the connecting seat through a ball hinge 1, the other end of the connecting tube 1 is slidably inserted in the connecting tube 2, and the connecting tube 2 is remote One end of the connecting pipe 1 is connected to the connecting plate 2 through the ball hinge 2, and the connecting plate 2 is equipped with a second connecting structure of the building structure; the pipe length direction of the connecting pipe 1 and the connecting pipe 2 is the same, and the pipe length direction of the connecting pipe 1 is arranged obliquely relative to the horizontal plane; the limiting member includes a movable member, an abutment block, an arc-shaped spring sheet and a mounting rod, and the movable member, the abutment block and the arc-shaped spring sheet are all arranged in the connecting pipe 1, and two movable members are provided and an abutment block is arranged between the two, and two arc-shaped spring sheets are provided and two movable members are arranged between the two; each movable member includes two movable members arranged along the connecting pipe The clamping blocks are arranged in sequence along the length direction of the connecting pipe 1, and the two clamping blocks in the same movable part are hinged and have a hinge axis; the two clamping blocks located in different movable parts are respectively fixed to the two ends of an arc-shaped spring sheet; each clamping block has an inclined side wall 1 parallel to the hinge axis, the four inclined side walls 1 are arranged in a rhombus shape, and a diagonal line of the rhombus is parallel to the length direction of the connecting pipe 1, and the abutment block has four inclined side walls 2, and the four inclined side walls 2 and the four inclined side walls 1 form a sliding fit corresponding to each other; the mounting rod is fixedly arranged on the abutment block On both sides of the connecting tube, a long hole is provided on the side wall of the connecting tube one, and the hole length direction of the long hole is the same as the tube length direction of the connecting tube one. One end of the mounting rod is fixedly connected to the connecting tube two after passing through the long hole; a plurality of clamping grooves arranged in sequence along its length direction are provided on the inner wall of the connecting tube one, and a clamping protrusion is provided on the clamping block; when the arc-shaped spring piece is in a natural state, the clamping protrusion and the clamping groove are in a separated state; when the abutting block drives the clamping block to overcome the elastic force of the arc-shaped spring piece and to be stretched outward through the cooperation of the oblique side wall two and the oblique side wall one, the clamping protrusion can be clamped in the clamping groove.

[0008] It can be seen from the above technical solutions that, compared with the prior art, the present invention, through the specific structural design of the inclined brace, on the one hand, when there is no earthquake, or when the electromechanical engineering facilities do not tend to shake violently, the inclined brace will hardly play a limiting role on the electromechanical engineering facilities. The main limiting role for the electromechanical engineering facilities is the vertical hanger. The connecting pipe 1 and the connecting pipe 2 are slidably connected. The connecting pipe 1 and the connecting pipe 2 will not prevent the slow deformation or displacement of the electromechanical engineering facilities due to thermal expansion and contraction (when the arc-shaped spring piece is deformed or the deformation is small, the clamping protrusion and the clamping groove are always in a separated state, and the connecting pipe 1 and the connecting pipe 2 can slide freely). During the initial installation, the connection length between the connecting pipe 1 and the connecting pipe 2 can also be The inclined brace can be easily installed in a suitable position by arbitrary adjustment; on the other hand, when an earthquake occurs or the electromechanical engineering facilities tend to shake violently, the abutment block moves quickly in the connecting pipe 1, and the rapid movement of the abutment block will cause the clamping blocks on both sides thereof to be pushed outward after overcoming the elastic force of the arc-shaped spring pieces, and along with the movement of the clamping block, the clamping protrusion will be stuck in the clamping groove, thereby limiting the continued movement of the abutment block; the above-mentioned design can avoid rapid and large-scale relative movement between the connecting pipe 1 and the connecting pipe 2, that is, ensure that the electromechanical engineering facilities will not shake significantly during an earthquake; the seismic support allows the electromechanical engineering facilities to deform or shift slowly, while preventing them from shaking significantly during an earthquake, thereby improving the seismic performance.

[0009] The preferred solution is that the vertical hanger is a telescopic rod with adjustable axial length, so that the height of the connecting seat can be adjusted, that is, the mechanical and electrical engineering facilities can achieve adjustment of the installation height. The specific structural form of the telescopic rod is preferably as follows: the vertical hanger includes a connecting plate 1, an externally threaded tube, an internally threaded tube and a mounting plate, and the first connecting structure of the building structure is arranged on the connecting plate 1; the externally threaded tube is arranged vertically and one end thereof is vertically fixed to the lower plate surface of the connecting plate 1, and the other end of the externally threaded tube is threadedly screwed to the internally threaded tube; the end of the internally threaded tube away from the externally threaded tube is fixed to the mounting plate, and the mounting plate is connected to the connecting seat; the connecting rod of the ball hinge 1 is connected and fixed to the mounting plate, and the ball seat of the ball hinge 1 is connected and fixed to the end of the connecting tube 1 away from the connecting tube 2. By designing the connecting plate 1, the building structure and the connecting seat can be reliably connected; by designing the externally threaded tube and the internally threaded tube, the height of the connecting seat can achieve a first-level adjustment.

[0010] A further preferred solution is that the vertical suspension rod also includes an adjusting screw and a clamping nut. The mounting plate is opened with a hole and the adjusting screw is threadedly provided. The adjusting screw is coaxially arranged with the internal threaded tube. The end of the adjusting screw away from the mounting plate is fixedly connected to the connecting seat. The clamping nut is screwed on the adjusting screw. One end of the clamping nut can be pressed against the side surface of the mounting plate away from the internal threaded tube. By designing the adjusting screw, the height of the connecting seat can be adjusted in two levels. Tightening the clamping nut can prevent the adjusting screw from rotating at will.

[0011] The preferred solution is that the first connection structure of the building structure includes a spring and a connection screw, the spring is arranged on the upper surface of the connection plate 1 and sleeved on the outer periphery of the connection screw, the plate surface of the connection plate 1 is provided with a connection hole adapted to the connection screw, and a connection nut is screwed on the connection screw. During specific installation, the lower end of the connection screw is screwed with the connection nut after passing through the spring and the connection hole on the connection plate 1 in sequence, and the connection nut is pressed against the lower plate surface of the connection plate 1. By designing the spring, the reliability of the fixation of the connection plate 1 to the building structure will not be affected when the electromechanical engineering facilities move slightly.

[0012] The preferred solution is that the electromechanical engineering facility installation structure includes a fixing plate and a U-shaped member, the lower surface of the connection seat is integrally formed with two fixing plates parallel to each other, a single fixing plate is arranged vertically, the U-shaped member is located below the connection seat, the two ends of the U-shaped member are respectively fixed to the two fixing plates by bolt connection, and the U-shaped member and the connection seat form a fixing cavity for the electromechanical engineering facility installation. During specific installation, the electromechanical engineering facility can be fixedly arranged in the fixing cavity for the electromechanical engineering facility installation formed by the U-shaped member and the connection seat, and the installation structure is simple and reliable.

[0013] The preferred solution is that the two long side walls of the long hole are slidably pressed against the outer side wall of the mounting rod at the same time, and the long hole also serves as a sliding guide. When there is no earthquake, the clamping block can move more smoothly inside the connecting pipe.

[0014] A preferred solution is that the inner arc surface of the arc-shaped spring piece is arranged close to the abutment block, so that the arc-shaped spring piece can more reliably and effectively elastically limit the clamping block.

[0015] A preferred solution is that a plurality of inclined tie rods are arranged in sequence along the circumference of the vertical suspension rod. A plurality of inclined tie rods can more effectively prevent the electromechanical engineering facilities from shaking rapidly and significantly.

[0016] The preferred solution is that the present invention also includes a prompting member, which includes a mounting member, a bell body, a rope body, and an impact ball. The mounting member is fixed on the vertical suspension rod. The bell body is made of metal material into a cylindrical shape. The length direction of the bell body is the same as the length direction of the vertical suspension rod. The upper end of the bell body is fixedly connected to the mounting member. One end of the rope body is fixedly connected to the inner top of the bell body. The impact ball is located inside the bell body. The impact ball is connected and fixed to the free end of the rope body. The rope body in a natural state is in a straight state and is coaxially arranged with the bell body. The straight rope body coincides with the center of the impact ball. There is a gap between the impact ball and the inner side wall of the bell body. When the impact ball swings with the rope body, the impact ball can collide with the inner side wall of the bell body. When an earthquake occurs, the impact ball can collide with the bell body as the rope body swings. The earthquake reminder can be given to the personnel below the anti-seismic support through the prompting member, reminding the personnel below to evacuate in time.

[0017] A preferred solution is that the present invention also includes an identification member, which includes a sleeve one, a tightening bolt one, an identification rod one, a sleeve two, a tightening bolt two and an identification rod two. The sleeve one is slidably sleeved on the connecting pipe one, the side wall of the sleeve one is opened and a tightening bolt one is threadedly screwed on, the tightening bolt one can press against the outer wall of the connecting pipe one, and one end of the identification rod one is fixedly connected to the sleeve one; the sleeve two is slidably sleeved on the connecting pipe two, the side wall of the sleeve two is opened and a tightening bolt two is threadedly screwed on, the tightening bolt two can press against the outer wall of the connecting pipe two, and one end of the identification rod two is fixedly connected to the sleeve two; the identification rod one and the identification rod two are arranged in an X shape, the outer wall of the identification rod one is in sliding contact with the outer wall of the identification rod two, the side wall of the identification rod one is provided with a marker one, the side wall of the identification rod two is provided with a marker two, and the marker one and the marker two can simultaneously correspond to the intersection position of the identification rod one and the identification rod two.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0027] See also Figures 1 to 6 The present invention discloses an anti-seismic support, including a vertical hanger, a connecting seat 7 and a diagonal rod, and the upper end of the vertical hanger is equipped with a first connecting structure of the building structure. The "vertical hanger" is equivalent to including a hanger body, and the axial direction of the hanger body is arranged vertically, and the "first connecting structure of the building structure" is used to fix the upper end of the vertical hanger and the building structure. The building structure here can be directly the indoor top wall, or it can be a component located above the electromechanical engineering facility and connected to the building structure. In order to facilitate installation, the vertical hanger is usually preferably a telescopic rod with adjustable axial length, so that the height of the connecting seat 7 can be adjusted, that is, the electromechanical engineering facility can achieve the adjustment of the installation height, and the telescopic rod plays a major role in fixing and limiting the electromechanical engineering facility.

[0028] The lower end of the vertical suspension rod is connected to the connection seat 7, and the connection seat 7 is equipped with an electromechanical engineering facility installation structure. The "electromechanical engineering facility installation structure" is used to fix the electromechanical engineering facility and the connection seat 7. The overall structure of the vertical suspension rod and the connection seat 7 realizes the fixed installation of the electromechanical engineering facility relative to the building structure. The vertical suspension rod can not only limit the vertical position of the electromechanical engineering facility, but also prevent the electromechanical engineering facility from shaking horizontally to a certain extent.

[0029] The diagonal tie rod can be designed with one or more diagonal tie rods. The multiple diagonal tie rods can be arranged in sequence along the circumference of the vertical hanger. The number of the diagonal tie rods can be determined according to the specific installation conditions of the electromechanical engineering facilities. Multiple diagonal tie rods can more effectively prevent the electromechanical engineering facilities from shaking sharply and rapidly.

[0030] The inclined brace specifically includes a connecting tube 19, a ball hinge 10, a connecting tube 211, a ball hinge 216, a connecting plate 217 and a stopper. One end of the connecting tube 19 is connected to the connecting seat 7 through the ball hinge 10, and the other end of the connecting tube 19 is slidably inserted in the connecting tube 211. The end of the connecting tube 211 away from the connecting tube 19 is connected to the connecting plate 217 through the ball hinge 216. The connecting plate 217 is equipped with a second connecting structure of the building structure. The "second connecting structure of the building structure" is used to connect the connecting plate 217 and the building structure in a fixed manner. Any structural form that can firmly connect the two can be adopted, usually in the form of bolt connection. More specifically, the end of the connecting tube 211 away from the connecting tube 19 is fixedly connected to the ball seat of the ball hinge 216, and the connecting plate 217 is vertically fixedly connected to the connecting rod of the ball hinge 216.

[0031] The pipe length direction of the connecting pipe 1 9 and the connecting pipe 2 11 is the same, and the pipe length direction of the connecting pipe 1 9 is arranged obliquely relative to the horizontal plane; that is, after the installation of the diagonal brace, the pipe length direction of the connecting pipe 1 9 is arranged obliquely relative to the telescopic direction of the telescopic end of the vertical hanger. When there is no earthquake, or when the electromechanical engineering facilities do not have a tendency to shake violently, the diagonal brace will hardly limit the electromechanical engineering facilities, and the vertical hanger is mainly used to limit the electromechanical engineering facilities; the connecting pipe 1 9 and the connecting pipe 2 11 are slidably connected, and this design facilitates the connection of the connecting pipe 2 11 to the building structure. At the same time, the connecting pipe 1 9 and the connecting pipe 2 11 will not prevent the slow deformation or displacement of the electromechanical engineering facilities due to thermal expansion and contraction. The cross-sectional shape of the connecting pipe 1 9 and the connecting pipe 2 11 can be any form that is convenient for processing and manufacturing. In the present invention, the rectangular tube structure is preferably used.

[0032] The limiting member includes a movable member, an abutment block 13, an arc-shaped spring piece 14 and a mounting rod 15. The movable member, the abutment block 13 and the arc-shaped spring piece 14 are all arranged in the connecting tube 9. There are two movable members and an abutment block 13 is arranged between the two. There are two arc-shaped spring pieces 14 and two movable members are arranged between the two. Each movable member includes two clamping blocks 12 arranged in sequence along the tube length direction of the connecting tube 9. The two clamping blocks 12 in the same movable member are hinged and have a hinge axis. The two clamping blocks 12 located in different movable members are respectively fixed to the two ends of an arc-shaped spring piece 14. Each clamping block 12 has an inclined side wall 120 parallel to the hinge axis, and the four inclined side walls 120 are arranged in a rhombus shape and a diagonal line of the rhombus is parallel to the tube length direction of the connecting tube 9. The abutment block 13 has four inclined side walls 130, and the four inclined side walls 130 are respectively parallel to the four inclined side walls 120. The four oblique side walls 130 are also arranged in a rhombus shape, and one oblique side wall 130 corresponds to one oblique side wall 120 respectively; the mounting rod 15 is fixedly arranged on both sides of the abutment block 13, and a long hole 90 is provided on the side wall of the connecting tube 1 9, and the hole length direction of the long hole 90 is the same as the tube length direction of the connecting tube 1 9, and one end of the mounting rod 15 is fixedly connected to the connecting tube 2 11 after passing through the long hole 90; on the inner wall of the connecting tube 1 9 There are multiple card slots 91 arranged in sequence along its length direction (preferably arranged at equal intervals), and a card protrusion 121 is provided on the card block 12; when the arc-shaped spring piece 14 is in a natural state, the card protrusion 121 and the card slot 91 are in a separated state, and when the abutment block 13 drives the card block 12 to overcome the elastic force of the arc-shaped spring piece 14 and stretch outward through the cooperation of the inclined side wall 2 130 and the inclined side wall 1 120, the card protrusion 121 can be engaged in the card slot 91.

[0033] In the preferred embodiment, a certain gap can be reserved between the abutment block 13 and the inclined side wall 1 120 in the normal state. When the abutment block 13 moves with the connecting tube 11, only after the abutment block 13 moves to a certain extent along the tube length direction of the connecting tube 9, the two inclined side walls 120 at the same end are respectively tightly attached to the corresponding two inclined side walls 130. The purpose of such design is that when the abutment block 13 moves slowly, the inclined side wall 1 120 and the inclined side wall 2 130 are gently and slowly pressed against each other, and due to the action of the arc-shaped spring sheet 14, the clamping blocks 12 on both sides of the abutment block 13 will not be stretched outward; on the contrary, when the abutment block 13 moves quickly, the inclined side wall 1 120 and the inclined side wall 2 130 are quickly in contact, and the clamping blocks 12 on both sides of the abutment block 13 will overcome the elastic force of the arc-shaped spring sheet 14 and be stretched outward.

[0034] After the electromechanical engineering facility of the present invention is installed, in a normal state, that is, when there is no earthquake or the electromechanical engineering facility does not tend to shake violently, the clamping protrusion 121 will not be stuck in the clamping groove 91 due to the elastic limiting effect of the arc-shaped spring piece 14; when the electromechanical engineering facility is slowly deformed or displaced due to thermal expansion and contraction, the connecting pipe 1 9 and the connecting pipe 2 11 will move relative to each other, and since the installation rod 15 is fixed to the abutment block 13 and the connecting pipe 2 11 at the same time, the abutment block 13 will also be in the connecting pipe 9, since the second inclined side wall 130 on the abutting block 13 is in close contact with the first inclined side wall 120 on the clamping block 12, and the moving speed of the abutting block 13 is slow, combined with the friction between the first inclined side wall 120 and the second inclined side wall 130 and the elastic force of the arc-shaped spring piece 14, the clamping blocks 12 located on both sides of the abutting block 13 will not be stretched outward, that is, the clamping protrusion 121 will not move in the direction close to the clamping groove 91, so that the clamping block 12 can also move smoothly along the length direction of the connecting pipe 9. On the contrary, when an earthquake occurs or the electromechanical engineering facilities tend to shake violently, the connecting pipe 1 9 and the connecting pipe 2 11 tend to move rapidly relative to each other, and the abutment block 13 moves rapidly in the connecting pipe 1 9. When the abutment block 13 moves rapidly, the clamping blocks 12 on both sides thereof will be stretched outward after overcoming the elastic force of the arc-shaped spring sheet 14. As the clamping block 12 moves, the clamping protrusion 121 will be stuck in the clamping groove 91, thereby limiting the continued movement of the abutment block 13; since the four inclined side walls 1 120 are arranged in a diamond shape and the abutment block 13 has four inclined side walls 2 130, no matter in which direction the abutment block 13 moves rapidly in the connecting pipe 1 9, the clamping protrusion 121 can be stuck in the clamping groove 91, thereby avoiding rapid and large-scale relative movement between the connecting pipe 1 9 and the connecting pipe 2 11, that is, ensuring that the electromechanical engineering facilities will not shake significantly. The earthquake-resistant support allows mechanical and electrical engineering facilities to deform or shift slowly while preventing them from shaking drastically during an earthquake.

[0035] When the vertical hanger adopts the structure of a telescopic rod, it can be implemented with reference to the existing technology, or the preferred solution provided by the present invention can be adopted. The preferred solution adopted by the present invention is as follows: the vertical hanger includes a connecting plate 1, an external threaded tube 2, an internal threaded tube 3 and a mounting plate 4, and the first connecting structure of the building structure is arranged on the connecting plate 1; the external threaded tube 2 is arranged vertically and one end thereof is vertically fixed to the lower side plate surface of the connecting plate 1, and the other end of the external threaded tube 2 is threadedly screwed to the internal threaded tube 3; the end of the internal threaded tube 3 away from the external threaded tube 2 is fixed to the mounting plate 4, and the mounting plate 4 is connected to the connecting seat 7; the connecting rod of the ball hinge 10 is connected and fixed to the mounting plate 4, and the ball seat of the ball hinge 10 is connected and fixed to the end of the connecting tube 9 away from the connecting tube 2 11. By screwing the external threaded tube 2 or the internal threaded tube 3, the height of the mounting plate 4 can be adjusted, and the position of the ball hinge 10 in the horizontal direction can also be adjusted.

[0036] The vertical suspension rod also includes an adjusting screw 5 and a clamping nut 6. The mounting plate 4 is provided with a hole and a threaded adjusting screw 5. The adjusting screw 5 is coaxially arranged with the internal threaded tube 3. The end of the adjusting screw 5 away from the mounting plate 4 is fixedly connected to the connecting seat 7. The clamping nut 6 is screwed on the adjusting screw 5. One end of the clamping nut 6 can be pressed against the side surface of the mounting plate 4 away from the internal threaded tube 3. By rotating the adjusting screw 5, the height of the mounting plate 4 can be adjusted twice, thereby adjusting the height of the connecting seat 7. After the vertical position of the connecting seat 7 is adjusted, tightening the clamping nut 6 can prevent the adjusting screw 5 from rotating at will.

[0037] The first connection structure of the building structure includes a spring 18 and a connection screw. The spring 18 is arranged on the upper surface of the connection plate 1 and sleeved on the outer periphery of the connection screw. The board surface of the connection plate 1 is provided with a connection hole adapted to the connection screw, and a connection nut is screwed on the connection screw. During specific installation, the lower end of the connection screw is screwed with the connection nut after passing through the spring 18 and the connection hole on the connection plate 1 in sequence, and the connection nut is pressed against the lower board surface of the connection plate 1. The purpose of this design is that when the electromechanical engineering facilities are slowly deformed or displaced due to thermal expansion and contraction, or when they are slightly displaced due to other reasons, the external threaded tube 2 and the internal threaded tube 3 are allowed to deflect to a certain extent, that is, when the electromechanical engineering facilities move slightly, it will not affect the reliability of the connection plate 1 and the building structure.

[0038] Mechanical and electrical engineering facilities are usually building water supply and drainage pipes, fire water pipes, heating pipes, ventilation pipes, air conditioning pipes and gas pipes, etc. The corresponding preferred installation method is as follows: the mechanical and electrical engineering facility installation structure includes a fixing plate 70 and a U-shaped member 8. The lower surface of the connecting seat 7 is integrally formed with two mutually parallel fixing plates 70. The single fixing plate 70 is arranged vertically. The U-shaped member 8 is located below the connecting seat 7. The two ends of the U-shaped member 8 are respectively fixed to the two fixing plates 70 by bolt connection. The U-shaped member 8 and the connecting seat 7 form a mechanical and electrical engineering facility installation and fixing cavity. During the specific installation, the mechanical and electrical engineering facilities can be fixedly arranged in the mechanical and electrical engineering facility installation and fixing cavity surrounded by the U-shaped member 8 and the connecting seat 7.

[0039] The two long side walls of the long hole 90 are slidably pressed against the outer side wall of the mounting rod 15 at the same time. This design can assist in limiting the abutment block 13 and the clamping block 12. When there is no earthquake or the electromechanical engineering facility does not have a tendency to shake violently, the clamping block 12 can smoothly move inside the connecting pipe 1 9. In some alternative embodiments, the guiding and limiting of the abutment block 13 and the clamping block 12 can also be achieved directly by relying on the sliding cooperation of the connecting pipe 1 9 and the connecting pipe 2 11.

[0040] The inner arc surface of the arc spring piece 14 is arranged close to the abutment block 13 , and the arc spring piece 14 can reliably and effectively elastically limit the clamping block 12 , ensuring that in a normal state, the second oblique side wall 130 on the abutment block 13 is in close contact with the first oblique side wall 120 on the clamping block 12 .

[0041] The present invention also includes a prompting member, which includes a mounting member 19, a bell body 20, a rope body 21 and an impact ball 22.

In a preferred embodiment of the present invention, the mounting member 19 is fixedly mounted on the internal threaded tube 3, the bell body 20 is made of metal material into a cylindrical shape, the length direction of the bell body 20 is the same as the length direction of the vertical suspension rod, and the upper end of the bell body 20 is aligned with the mounting member 1. 9 is fixedly connected, one end of the rope body 21 is fixedly connected to the inner top of the bell body 20, the impact ball 22 is located inside the bell body 20, the impact ball 22 is fixedly connected to the free end of the rope body 21, the rope body 21 in a natural state is in a stretched state and is coaxially arranged with the bell body 20, the stretched rope body 21 coincides with the center of the impact ball 22, there is a gap between the impact ball 22 and the inner side wall of the bell body 20, when the impact ball 22 swings with the rope body 21, the impact ball 22 can collide with the inner side wall of the bell body 20. After the seismic bracket is installed, the internal threaded tube 3 is arranged vertically, and correspondingly, the bell body 20 is also arranged vertically, the flexible rope body 21 is stretched and straightened by the impact ball 22, the rope body 21 in the stretched state is arranged vertically, and the impact ball 22 does not contact the inner wall of the bell body 20; when an earthquake occurs, the impact ball 22 will shake, and the impact ball 22 will hit the metal bell body 20 (usually steel material can be selected), thereby making a jingle sound, thereby reminding the personnel located below the seismic bracket to stay away, to prevent the electromechanical engineering facilities or the seismic bracket from falling off and hitting the people located below; at the same time, the impact balls 22 are all located on the inner side of the bell body 20. The purpose of this design is to prevent the wind from blowing the impact balls 22 to shake. In the absence of an earthquake, the impact balls 22 will not hit the bell body 20, to avoid misjudgment by the personnel below.

[0042] The present invention also includes an identification member, which includes a sleeve 23, a tightening bolt 24, an identification rod 25, a sleeve 26, a tightening bolt 27 and an identification rod 28. The sleeve 23 is slidably mounted on the connecting pipe 9, and the side wall of the sleeve 23 has a hole and is threadedly provided with a tightening bolt 24. The tightening bolt 24 can press against the outer wall of the connecting pipe 9 (that is, when the tightening bolt 24 does not press against the outer wall of the connecting pipe 9, the sleeve 23 can slide freely relative to the connecting pipe 9, and when the tightening bolt 24 presses against the outer wall of the connecting pipe 9, the connection position of the sleeve 23 and the connecting pipe 9 is relatively fixed), and one end of the identification rod 25 is fixedly connected to the sleeve 23; the sleeve 26 is slidably mounted on the connecting pipe 11, and the side wall of the sleeve 26 has a hole and is threadedly provided with a tightening bolt Bolt 27, the tightening bolt 27 can press against the outer side wall of the connecting pipe 11 (that is, when the tightening bolt 27 is not pressed against the outer side wall of the connecting pipe 11, the sleeve 26 can slide freely relative to the connecting pipe 11, and when the tightening bolt 27 presses against the outer side wall of the connecting pipe 11, the connection position of the sleeve 26 and the connecting pipe 11 is relatively fixed), one end of the identification rod 28 is fixedly connected to the sleeve 26; the identification rod 1 25 and the identification rod 28 are arranged in an X shape, the outer side wall of the identification rod 1 25 is in sliding contact with the outer side wall of the identification rod 28, a marker 1 250 is provided on the side wall of the identification rod 1 25, and a marker 280 is provided on the side wall of the identification rod 28, and the marker 1 250 and the marker 2 280 can correspond to the intersection position of the identification rod 1 25 and the identification rod 2 28 at the same time. The marker 1 250 and the marker 2 280 may specifically adopt any structural form that is easy to observe, for example, they may be partially configured into a groove shape, a protrusion shape, etc.

[0043] When no earthquake occurs and the seismic support is in a static state, the positions of sleeve 1 23 and sleeve 2 26 are adjusted so that identification rod 1 25 and identification rod 2 28 are arranged in an X shape, and it is ensured that marker 1 250 and marker 2 280 correspond to the intersection positions of identification rod 1 25 and identification rod 2 28 at the same time, and the distance between sleeve 1 23 and sleeve 2 26 is long enough, and sleeve 1 23 and sleeve 2 26 do not affect the relative movement between connecting pipe 1 9 and connecting pipe 2 11.

[0044] When the electromechanical engineering facilities are slowly deformed or shifted due to thermal expansion and contraction, relative movement occurs between the connecting pipe 1 9 and the connecting pipe 2 11. At this time, the marker 1 250 and the marker 2 280 are misaligned with the actual intersection position of the marker pole 1 25 and the marker pole 2 28, that is, the marker 1 250 and the marker 2 280 do not correspond to the actual intersection position of the marker pole 1 25 and the marker pole 2 28. During routine inspections, the inspection personnel can directly observe the positional relationship between the marker 1 250 and the marker 2 280 and the actual intersection position of the marker pole 1 25 and the marker pole 2 28, so as to judge whether the electromechanical engineering facilities are securely installed on the seismic support, and judge the degree of deformation or displacement of the electromechanical engineering facilities, so as to timely discover problems and carry out maintenance.
