Description

Technical Field

[0001] The present invention relates to a steel truss siphon structure, in particular to a siphonic rainwater drainage system inside a high-altitude steel truss. Background Art

[0002] The task of a building rainwater drainage system is to promptly drain rainwater and snowmelt on the building roof, avoiding rainwater overflow on the roof caused by roof ponding, so as to ensure normal living and production activities of people.

[0003] Siphon generally refers to the siphon phenomenon. The siphon principle is to utilize the principle of pressure difference. In a closed container, the liquid levels are the same and the pressures are equal. The siphon pipe is filled with water and there is no air. The water inlet end has a higher water level. The outlet is blocked with a palm or other object. At this time, the pressure inside the pipe is equal everywhere. After everything is arranged, the outlet is opened. Although the atmospheric pressures on both sides are equal, the water level at the water inlet end is higher and the pressure is greater, pushing the incoming water to continuously flow out of the outlet.

[0004] The existing technology is to adopt the siphon technology on the building roof to quickly drain the rainwater or other water on the building roof, thereby alleviating the problem of roof ponding. Most traditional installation methods directly connect the siphon pipe to the main structure of the steel truss. The siphon suction force generated when the siphon system works directly acts on and is transmitted to the main structure of the steel truss, which is likely to cause relatively large vibrations to the steel truss and the installation surface, and there are relatively large potential safety hazards. Summary of the Invention

[0005] The present invention provides a siphonic rainwater drainage system inside a high-altitude steel truss, which can effectively solve the above problems.

[0006] The present invention is implemented as follows:

[0007] A siphonic rainwater drainage system inside a high-altitude steel truss includes:

[0008] A steel truss main body, the steel truss main body includes a steel truss cross bar, and a steel truss connecting rod perpendicularly and fixedly connected to the steel truss cross bar;

[0009] A plurality of siphonic rainwater inlets arranged on the roof;

[0010] A siphon pipe extending downward and bent from the siphonic rainwater inlet;

[0011] A force equalizing structure connecting the steel truss connecting rod and the horizontal section of the siphon pipe;

[0012] The uniform force structure includes several locking structures locked on the horizontal section of the siphon pipeline, a yaw structure locked inside the locking structure, a first steel cable with one side fixedly connected to the top of the yaw structure and the other side locked at the midpoint of the bottom of the steel truss connecting rod, and a second steel cable with one side locked at the top of the locking structure and the other side locked at the side of the bottom of the steel truss connecting rod. The first steel cable, the second steel cable, and the steel truss connecting rod form a triangular structure.

[0013] As a further improvement, the nodes at the bottoms of the first steel cable and the second steel cable are arranged in a staggered manner.

[0014] As a further improvement, the yaw structure includes a yaw rod connected to the locking structure, a swing device sleeved at the midpoint of the yaw rod, and a balance device arranged on the side of the yaw rod away from the siphon rain bucket.

[0015] As a further improvement, the swing device includes a bushing nested in the yaw rod, a sleeve sleeved outside the bushing, a hinge head locked on the sleeve, an electric push rod with an output shaft hinged on the hinge head, and a mounting facade hinged at the other end of the electric push rod.

[0016] As a further improvement, the balance device includes an extension rod locked on the side of the yaw rod away from the siphon rain bucket. The extension rod is a trapezoid-like structure. An inclined surface of the extension rod extends outward and is fixedly connected with a slideway. A plurality of linear motors are slidably connected on the slideway, and counterweight blocks are loaded on the linear motors. The counterweight blocks are connected by springs.

[0017] As a further improvement, limiting pieces are arranged on both sides of the slideway, and the limiting pieces are attached to the outside of the linear motors.

[0018] As a further improvement, a water volume sensor is arranged in the siphon rain bucket, and the linear motor is electrically connected with the water volume sensor.

[0019] As a further improvement, a downward drain pipe extends downward from the horizontal section of the siphon pipeline. The outer peripheral surface of the downward drain pipe is locked on the wall through several clamps, and adjacent clamps are connected by a rubber strip. The adjacent rubber strips face in opposite directions.

[0020] As a further improvement, the steel truss connecting rod includes two U-shaped locking frames abutted against the bottom of the steel truss cross bar, a damping box sleeved outside the U-shaped locking frame and welded on the steel truss cross bar and the steel truss connecting rod, and particle damping is filled inside the damping box.

[0021] As a further improvement, the locking structure includes a first clamping seat movably clamped on the horizontal section of the siphon pipe, a connecting rib extending from the first clamping seat to a side away from the siphon pipe, and a second clamping seat connected to the connecting rib and clamped on the deflection rod.

[0022] The beneficial effects of the present invention are:

[0023] The present invention connects the siphon pipe and the siphon rainwater bucket to the uniform force structure first, and then connects them to the steel truss main body through the uniform force structure. The elastic bounce of the steel cable and the external placement of the yaw structure can offset part of the vibration force generated by the siphon, thereby reducing the influence of the siphon force on the steel truss and the building body. In addition, in order to prevent the vibration force formed by the siphon from having an excessive influence on the steel truss main body, the first steel cable and the second steel cable are respectively fixed on different rods to form a triangular support body, thereby improving the support performance while performing multi-point dispersion.

[0034] To make the embodiments of the present invention, all fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0036] In the existing structure, there is a structure for connecting a siphonic rainwater bucket and a siphonic pipe to some external steel sheets and pipes to avoid directly installing the siphonic rainwater bucket and the siphonic pipe into the building and avoid the influence of the siphon force on the building main body. However, it can be found that the external steel sheets and pipes are still nailed to the building by means of screws. In other words, only the siphonic components are externalized, and finally they are still connected to the building or the steel truss through the same node. Moreover, when the siphon force is generated, the entire pipe shakes, and it is difficult to maintain the balance of the external pipes and steel sheets. To solve the above technical problems, the following technical solutions are proposed in this case:

[0037] Refer to Figures 1-9As shown in the figure, a siphonic rainwater drainage system inside a high-altitude steel truss includes: a steel truss main body 1, where the steel truss main body 1 includes a steel truss cross bar 11 and a steel truss connecting rod 12 perpendicularly and fixedly connected to the steel truss cross bar 11; several siphonic rainwater funnels 2 provided on the roof; a siphonic pipe 3 extending downward and bent from the siphonic rainwater funnel 2; a force equalizing structure 4 connecting the steel truss connecting rod 12 and the horizontal section of the siphonic pipe 3; the force equalizing structure 4 includes several locking structures 41 locked on the horizontal section of the siphonic pipe 3, a yaw structure 42 locked inside the locking structure 41, a first steel cable 43 with one side fixedly connected to the top of the yaw structure 42 and the other side locked to the midpoint of the bottom of the steel truss connecting rod 12, and a second steel cable 44 with one side locked to the top of the locking structure 41 and the other side locked to the side of the bottom of the steel truss connecting rod 12. The first steel cable 43, the second steel cable 44, and the steel truss connecting rod 12 form a triangular structure.

[0038] First, fix the siphonic rainwater funnel 2 to the roof so as to collect rainwater and then cause a siphonic effect. Then, connect the siphonic pipe 3 to the siphonic rainwater funnel 2. In this embodiment, the siphonic pipe 3 is divided into three parts. One part is the L-shaped part connected to the siphonic rainwater funnel 2, the second part is the horizontal section, and the third part is the downcomer 31 connected to the drainage pipe. Lock and fix several locking structures 41 on the horizontal section of the siphonic pipe 3. The locking structure 41 serves as a connecting medium. At the other end of the locking structure 41, lock and fix the yaw structure 42. The yaw structure 42 is in a closed state under normal conditions and can be switched to an activated state during rainy days or when a large amount of drainage is required. However, the main connecting components are the first steel cable 43 and the second steel cable 44. Among them, the first steel cable 43 is in a vertically connected state, while the second steel cable 44 is in an inclined connected state. It should be noted that the fixed node of the first steel cable 43 is the midpoint of the steel truss connecting rod 12, which can not only achieve a better tensile effect but also achieve a force balance effect. The second steel cable 44 is arranged at the side of the steel truss connecting rod 12, which is also the side corresponding to one side of the force equalizing structure 4, and can pull the force equalizing structure 4 from one side to avoid the inclination and imbalance phenomenon caused by the setting of the force equalizing structure 4.

[0039] As mentioned above, while reducing the vibration forces of the steel truss main body 1 and the building main body, the issue of balance also needs to be considered. Therefore, although the first steel cable 43, the second steel cable 44, and the steel truss connecting rod 12 form a triangular structure, providing a stable support effect, the nodes at the bottoms of the first steel cable 43 and the second steel cable 44 are arranged in a staggered manner. That is, the node at the bottom of the first steel cable 43 is located on the yaw structure 42, while the node at the bottom of the second steel cable 44 is located on the locking structure 41, which to a certain extent avoids stress concentration. If the first steel cable 43 and the second steel cable 44 intersect at a point, when the force equalizing structure 4 is stressed, the same node will bear the force, which is likely to cause a large tensile force on both steel cables, and the steel cables are prone to damage.

[0040] Meanwhile, when the siphon rainwater bucket 2 and the siphon pipe 3 vibrate, even if the force equalizing structure 4 pulls the steel truss main body 1, it will also act on different nodes of the steel truss connecting rod 12. At this time, since the connection node between the steel truss connecting rod 12 and the top of the first steel cable 43 is the midpoint, the vibration force can be relatively evenly dispersed. And the connection node between the steel truss connecting rod 12 and the top of the second steel cable 44 is located above the welding point of the steel truss connecting rod 12 and the steel truss cross bar 11, and the steel truss cross bar 11 can be used to disperse the vibration force. Therefore, the vibration forces generated by the siphon rainwater bucket 2 and the siphon pipe 3 can be evenly dispersed, without having to consider the problems of building area damage or steel truss depression that may occur in the existing single-node installation.

[0041] Among them, the locking structure 41 includes a first clamping seat 411 that is movably clamped on the horizontal section of the siphon pipe 3, a connecting rib 412 extending from the first clamping seat 411 away from the siphon pipe 3, and a second clamping seat 413 that is connected to the connecting rib 412 and clamped on the yaw rod 421. It should be emphasized that in this embodiment, regardless of what kind of clamping seat, it adopts the threaded cooperation method of a clamp and a screw, which are all prior arts and will not be elaborated in detail here. More peculiarly, when the first clamping seat 411 cooperates with the siphon pipe 3, the first clamping seat 411 is not in a completely locked state, and the first clamping seat 411 and the siphon pipe 3 can rotate relative to each other. When the first clamping seat 411 is subjected to an external force, it can rotate at a certain angle along the siphon pipe 3, thereby driving the yaw structure 42 on the force equalizing structure 4 to change the angle, while the second clamping seat 413 is completely in a locked state with the yaw rod 421.

[0042] Among them, the specific composition of the yaw structure 42 is as follows: the yaw structure 42 includes a yaw rod 421 connected to the locking structure 41, a swinging device 422 sleeved at the midpoint of the yaw rod 421, and a balancing device 423 provided on the side of the yaw rod 421 away from the siphonic rainwater hopper 2. In this embodiment, the yaw rod 421 is a specific bridging rod, acting as a bridging medium between the steel truss main body 1 and the siphonic pipe 3, so that the force on the siphonic pipe 3 will not directly act on the steel truss main body 1 and the building main body.

[0043] As mentioned in the above description, the yaw structure 42 has two states. One is the daily fixed state, and the other is the state that requires a large amount of drainage. In the first state, the yaw structure 42 does not need to act. At this time, the first steel cable 43 and the steel truss connecting rod 12 are in a vertical state, and the first steel cable 43 and the second steel cable 44 form a quasi-triangular state. At this time, the support balance performance is the best and no drainage is required. Once it enters the second state, at this time, the siphonic rainwater hopper 2 collects a large amount of rainwater, and the siphonic pipe 3 is draining a large amount of water. The entire siphonic pipe 3 causes large-frequency vibrations under the influence of water. Therefore, the swinging device 422 can be used at this time;

[0044] The specific setting of the swinging device 422 is as follows: the swinging device 422 includes a bushing 4221 nested in the yaw rod 421, a sleeve 4222 sleeved outside the bushing 4221, a hinge head 4223 locked on the sleeve 4222, an electric push rod 4224 whose output shaft is hinged on the hinge head 4223, and an installation facade 4225 hinged on the other end of the electric push rod 4224. When a large amount of drainage requires the swinging device 422 to be activated, by driving the electric push rod 4224 to push out, the sleeve 4222 and the bushing 4221 drive the yaw rod 421 to rotate. Since the first clamping seat 411 and the siphonic pipe 3 are movable, the yaw rod 421 will rotate along the siphonic pipe 3. By continuously reciprocating the electric push rod 4224, first, the position of the yaw rod 421 is changed, so that the distance between the yaw rod 421 and the steel truss main body 1 becomes slightly longer, thereby changing the tension state of the first steel cable 43 and the second steel cable 44, so that part of the vibration kinetic energy is digested by elastic deformation. Second, because the electric push rod 4224 itself is also installed on an installation facade 4225, it will receive part of the vibration force of the siphonic pipe 3 during its reciprocating motion. Furthermore, the vibration energy is dissipated by using the potential energy of the reciprocating motion, increasing the force unloading nodes, and thus achieving the effect of multi-point force unloading.

[0045] It should be noted that the first steel cable 43 and the second steel cable 44 have a certain elasticity and can be stretched to a certain extent without breaking for a long time. Therefore, when using them to connect the yaw rod 421 and the steel truss connecting rod 12, they will not break during the drainage process.

[0046] In order to improve the locking force at both ends of the first steel cable 43, the upper end of the first steel cable 43 is locked to the steel truss connecting rod 12 through the third clamping seat 431, and the lower end of the first steel cable 43 is locked to the swing rod 421 through the fourth clamping seat 432.

[0047] Among them, regarding the activation of the swing structure 42, it can be activated manually, or the electric push rod 4224 can be electrically connected to environmental sensors outdoors, such as rain and snow sensors, water sensors, etc., and it can be automatically opened when it rains heavily or there is a large amount of water accumulation.

[0048] Due to the slope of the roof or the uneven flow of water, among the multiple groups of siphonic rainwater inlets 2 and siphonic pipes 3 provided, it is possible that some or a single siphonic rainwater inlet 2 and siphonic pipe 3 have a large amount of water flowing in. Therefore, only the steel truss connecting rods 12 at one or two nodes are stressed, which extremely easily causes uneven stress and local deformation.

[0049] Therefore, the balancing device 423 includes an extension rod 4231 that locks the side of the swing rod 421 away from the siphonic rainwater inlet 2. The extension rod 4231 is of a trapezoid-like structure. An inclined surface of the extension rod 4231 extends outward and is fixedly connected with a slideway 4232. A number of linear motors 4233 are slidably connected to the slideway 4232. A counterweight 4234 is loaded on the linear motor 4233. The counterweights 4234 are connected by a spring 4235. Among them, the extension rod 4231 is provided to avoid the second clamping seat 413 on the locking structure 41. And, a small hole for screw connection of the second clamping seat 413 is left at the bottom of the extension rod 4231. The trapezoid-like structure with an inclined surface is actually to avoid being directly arranged on the outside of the extension rod 4231, which may cause the entire balancing device 423 to be too inclined. Therefore, it is arranged on the inclined trapezoidal surface to form a balance with the swing rod 421. By setting the linear motor 4233 to cooperate with the slideway 4232, the position of the counterweight 4234 can be changed. For example, when the leftmost siphonic rainwater inlet 2 and siphonic pipe 3 are filled with water, at this time, by controlling the movement of the linear motor 4233 on the slideway 4232, the linear motor 4233 carrying the counterweight 4234 can be moved to the right to form an equal pressure with the vibration of the left siphonic rainwater inlet 2 and siphonic pipe 3, so that each point on the entire steel truss main body 1 can receive a uniform and stable downward pressure, avoiding the phenomenon of local compression and rapid deformation.

[0050] During the sliding process of the linear motor 4233, since it needs to carry a counterweight 4234, in order to limit its sliding orientation and prevent it from swaying left and right when cooperating with the slideway 4232, limiting pieces 4236 are provided on both sides of the slideway 4232. The limiting pieces 4236 are attached to the outer side of the linear motor 4233, and the linear motor 4233 is always in contact with the limiting pieces 4236 during the sliding process.

[0051] Different counterweights 4234 are connected together by springs 4235. When sliding, the linear motor 4233 can be more labor-saving under the elastic drive of the previous linear motor 4233. If the linear motor 4233 does not receive a movement signal, it will be fixed in place and will not be pushed by the springs 4235 on the adjacent counterweights 4234.

[0052] The basis for judging whether the linear motor 4233 moves is as follows: a water volume sensor (not shown in the figure) is provided in the siphonic rainwater bucket 2, and the linear motor 4233 is electrically connected to the water volume sensor. For example, when only the left siphonic rainwater bucket 2 and the siphon pipe 3 are filled with water, the water volume sensors in the left siphonic rainwater bucket 2 and the siphon pipe 3 sense the water inflow, and then the linear motor 4233 will be driven to move away from the corresponding siphonic rainwater bucket 2 and siphon pipe 3 to form a balance at other positions until it moves near the siphonic rainwater bucket 2 and siphon pipe 3 without water inflow. When all the water volume sensors receive the water inflow signal, all the linear motors 4233 will not operate.

[0053] After the water volume sensor loses the signal, it means that the water inflow process is over, and all the linear motors 4233 will move to their original positions under the control of the program to form a reset, waiting for the next water inflow to judge whether there is a movement phenomenon. Among them, the movement principle of the linear motor 4233, the opening and closing principle of the water volume sensor, and the principle of controlling the start and stop of the linear motor 4233 through the control program are all prior arts and will not be elaborated in detail here.

[0054] The horizontal section of the siphon pipe 3 extends downward to form a downward drain pipe 31. On the premise that the locking structure 41 is fixed on the horizontal section of the siphon pipe 3, the downward drain pipe 31 also needs to be fixed. Therefore, in the prior art, several clamps 311 are used to lock the outer peripheral surface of the downward drain pipe 31 to the wall surface, and the wall surface shares part of the vibration force. However, if this is the only measure, it will cause excessive vibration to the wall surface in the long term. Therefore, adjacent clamps 311 are connected by a rubber strip 3111, and adjacent rubber strips 3111 face in opposite directions. When the downward drain pipe 31 vibrates, the vibration will be transmitted to the clamps 311, and then the clamps 311 will conduct the vibration to the rubber strips 3111. The rubber strips 3111 will continuously contract, bend, deform, etc., so as to offset part of the vibration force and reduce the acting force on the wall. The opposite directions of adjacent rubber strips 3111 can ensure the uncertainty of force transmission, so that the force will not be concentrated in a certain direction.

[0055] In the setting of the steel truss main body 1, there are two parts, namely the steel truss cross bar 11 and the steel truss connecting rod 12. The connection strength between the two often also means the stability of the entire roof support system. Therefore, in order to improve the stability of the two, the steel truss connecting rod 12 includes two U-shaped locking frames 121 that abut against the bottom of the steel truss cross bar 11, and a vibration damping box 122 that is sleeved outside the U-shaped locking frames 121 and welded to the steel truss cross bar 11 and the steel truss connecting rod 12. The inside of the vibration damping box 122 is filled with particle damping. When the entire steel truss main body 1 receives the vibration conduction of the first steel cable 43 and the second steel cable 44, part of the vibration force will be conducted to the vibration damping box 122. Through the inelastic collision and friction of the particle damping in the vibration damping box 122, a damping effect is generated during the structural vibration, so as to achieve the purpose of suppressing vibration. The position where the vibration is suppressed is the connection between the steel truss cross bar 11 and the steel truss connecting rod 12, where the vibration is the strongest, so the effect of absorption and conversion is also the best. The fixed welding of the U-shaped locking frame 121 plays a role of rigid connection.

[0056] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
