Description

Technical Field

[0001] The utility model relates to a building drainage system, and more specifically, to a downspout system for a steel structure building. Background Art

[0002] Steel structure buildings are widely used in engineering projects due to their advantages such as light weight, high strength, large span, and low cost. Factory buildings, multi-story or high-rise steel structure buildings, etc. are the most common. As an essential part of a building (including steel structure buildings, concrete buildings, etc.), the downspout plays a direct role in roof drainage.

[0003] According to the on-site construction progress, construction materials must be delivered to the site in advance, and some materials need to be prefabricated before installation, including downspout materials. Or due to limited space in the on-site construction (material storage) area, the materials are stacked near the building location in an open and empty area according to the building position. The downspout is usually installed after the installation of the gutter is completed, which belongs to the last stage of the construction of steel structure buildings or other buildings. Inevitably, during the stacking process, it is affected by the environment and human activities, such as sun exposure, trampling, stacking and pressing of other materials on it, or problems with the quality of the materials themselves, etc., resulting in the ovality of the pipe being affected and increasing the difficulty of fixing the downspout.

[0004] The downspout is installed close to the building wall. Usually, throughout the entire height, since the allowable deviation in verticality of the steel column also directly affects the deviation in verticality of the downspout, and the overall is not straight. The pipe clamps used are mostly matching pipe clamps of the same material (PVC). The connection between the tail of the pipe clamp and the building wall is not firm, and the fastening degree of the head of the pipe clamp is also affected by the verticality and is not firmly installed. Often, parts of the downspout that have been installed for a short time will fall off or become loose and inclined. The downspout is installed from top to bottom, and the downspouts are connected by one-way anti-drop sealing ports to be fixedly connected into an entire downspout. However, if some sections fall off or become loose and inclined, the repair is difficult either due to high-altitude operations or due to the connection method. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a downspout system for a steel structure building, which can at least achieve the purpose of being more firm after installation and maintaining the overall verticality of the downspout.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: a downspout system for a steel structure building, including:

[0007] Multiple sections of downspouts, and the single-section downspouts are connected by corrugated short joints;

[0008] Nuts, which are fixedly arranged on the steel columns of the steel structure building or the embedded steel plates at intervals along the height direction;

[0009] Pipe clamps, one end of which is connected to a single-section downspout, and the other end is connected to a nut.

[0010] Further, the pipe clamp includes a double semi-circular clamping clip and a stud fixedly connected to one side of the double semi-circular clamping clip, and the stud is threadedly connected to a nut.

[0011] Further, a rubber pad is added inside the double semi-circular clamping clip or the whole double semi-circular clamping clip is wound with a plastic material.

[0012] Further, the upper end of the corrugated short section is sleeved outside the bottom of the upper downspout, and the lower end of the corrugated short section is inserted inside the top of the lower downspout.

[0013] Further, a cloth tube is connected to the bottom end water downspout.

[0014] Further, a water receiving hopper is connected to the top end first water downspout.

[0015] Further, a guide rope is arranged in the middle of the downspout along the height direction.

[0016] Further, a long bolt is horizontally penetrated through the water receiving hopper, and two limit nuts are threadedly connected to the long bolt. The top end of the guide rope is limited and fixed by the two limit nuts; a ground hook is arranged at the center of the ground opposite to the bottom end of the bottom end water downspout, and the bottom end of the guide rope is fixedly connected to the ground hook.

[0017] The utility model uses a nut as the connection basis of the pipe clamp, and the basis is more firm. It effectively utilizes the distance between the structure and the downspout. At the same time, the straightness of the downspout can be adjusted secondly to make the whole downspout straight. The downspout is connected by corrugated short sections, which divides the whole into parts, neither affecting the overall beauty and function, nor making it more convenient to replace and set some pipe sections. A guide rope is added inside the downspout to reduce the weight of the rain hitting, impacting and flowing down along the pipe wall on the pipe wall, making the downspout more firm.

[0026] In order to enable those skilled in the art to better understand the present utility model, the present utility model will be further clearly and completely described below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflict, the implementation modes and features in the embodiments in this application can be combined with each other

[0027] A downspout system for a steel structure building provided by a typical implementation mode of the present utility model includes multiple sections of downspouts 7, nuts 1 and pipe clamps 3

[0028] As shown in Figure 5 , single sections of downspouts 7 are connected by corrugated nipples 8. Nuts 1 are fixedly arranged at intervals in the height direction on the steel columns of the steel structure building or on the embedded steel plates. As shown in Figure 6 , one end of the pipe clamp 3 is connected to a single section of downspout 7, and the other end is connected to the nut 1

[0029] In this implementation mode, the nut 1 serves as the connection foundation of the pipe clamp. One end of the nut 1 is spot - welded to the steel column (if it is other walls, steel plates can be embedded or set), and the other end is connected to the tail of the pipe clamp 3. The nut 1 adopts a long nut, which greatly utilizes the thickness distance between the steel column and the structural wall surface. At the same time, it can also make the downspout 7 closer to the structural wall surface, increasing stability. By connecting the downspouts 7 through corrugated nipples 8, when some downspouts need to be replaced, they can be replaced separately, achieving effective separation of the whole and parts, and being more practical and economical

[0030] In a preferred implementation mode, as shown in Figure 6 , the pipe clamp 3 includes a double - semi - circular clamp and a stud fixedly connected to one side of the double - semi - circular clamp, and the stud is threadedly connected to the nut 1

[0031] In this implementation mode, the tail of the pipe clamp 3 is threadedly connected to the nut 1 by a stud matching the nut 1, and can be rotated to adjust the extending length, playing a secondary adjustment role in the overall straightness of the downspout 7

[0032] The pipe clamp 3 adopts a double semi-circular clamping device. It is acceptable to add a rubber pad inside or wrap the whole with plastic material. This can not only play an anti-corrosion role but also enable the pipe clamp 3 to tightly hold the downspout 7. A few turns of plastic wrap can be tightly wound around the pipe section of 100 - 150 mm around the downspout 7 fixed by the pipe clamp 3 to increase the friction of this section. Using a metal pipe clamp is convenient for disassembly and replacement and can ensure the service life.

[0033] In a preferred embodiment, as Figure 5 shown, the upper end of the corrugated short section 8 is sleeved on the outer side of the bottom of the upper downspout 7, and the lower end of the corrugated short section 8 is inserted into the inner side of the top of the lower downspout 7. An anti-leakage operation of applying sealant and tying it tightly with a binding band 9 can be adopted.

[0034] In a preferred embodiment, as Figure 4 shown, the bottom end water downspout 7 is connected with a cloth tube 10. The ground water outlet adopts a straight-through cloth tube 10 without adding an end diversion elbow, reducing the impact of rainwater falling from a height, reducing the impact on the overall downspout, and reducing the splashing of rainwater in the pipe when it lands.

[0035] In a preferred embodiment, a diversion rope 6 is provided in the middle of the downspout 7 along the height direction. The diversion rope 6 is cylindrical or strip-shaped. The top first downspout 7 is connected with a water receiving hopper 4. A long bolt 5 is horizontally penetrated through the water receiving hopper 4. Two limit nuts are threadedly connected to the long bolt 5. The top end of the diversion rope 6 is limited and fixed by the two limit nuts, so that the diversion rope 6 is vertically maintained in the middle of the downspout 7. A ground hook 11 is arranged at the center of the ground opposite to the bottom end of the downspout, and the bottom end of the diversion rope 6 is fixedly connected with the ground hook 11.

[0036] In this embodiment, setting the diversion rope 6 can make full use of the surface tension of water, better attract the water flow, and reduce the influence of the external force of rainwater on the pipe wall. A long bolt 5 is arranged at the connection between the gutter and the water receiving hopper 4, placing the diversion rope 6 at the center of the downspout 7 and tying it tightly at the ground to prevent the diversion rope 6 from shaking and hitting the inner wall of the downspout 7, causing the downspout 7 to loosen and fall. If leaves or other sundries enter the downspout 7, the bottom of the diversion rope 6 can be untied and shaken by hand to facilitate the falling and discharging of the sundries.

[0037] At the outlet of the downspout 7, on the scattered water floor or other surfaces, an asphalt waterproof paint layer 12 can be thickly coated or an anti-scouring plate can be set, etc.

[0038] The following provides a relatively specific embodiment to further clearly and completely illustrate the technical solution claimed by the utility model.

[0039] First, perform pre-installation and layout on the ground. Mainly determine the opening positions of the downpipe gutters (the position of the downpipe can also be changed with elbows). After the steel structure building is constructed according to the drawings, there will inevitably be deviations from the actual dimensions, and it is very likely to conflict with the surrounding structures (pipe galleries, pipelines, electrical and instrumentation cable trays, etc.). It is necessary to determine the final position of the downpipe 7. Even so, during the actual installation process, there are still places that need to be adjusted.

[0040] The installation process flow of the downpipe 7 system is: positioning and setting out → (setting embedded steel plates) spot-welding nuts → installing pipe clamps → installing water receiving funnels or elbow pipes → installing guide ropes → installing downpipes and connecting the downpipes → connecting the guide ropes to the ground → painting waterproof asphalt paint or setting erosion prevention plates on the apron or other ground.

[0041] Install the downpipe 7 from top to bottom. First, hang a plumb bob at the water receiving funnel 4 to draw a straight line. Determine the setting position of the nut 1 according to the length of each section of the downpipe 7. The setting principle of the nut 1 is to set it at both ends according to the length of each section of the downpipe 7. If the pipeline is long, an additional one can be set in the middle.

[0042] Just spot-weld the nut 1. When spot-welding, use a spirit level. The long nut after welding should ensure that the side is horizontal. Therefore, there is a phenomenon that the nut does not fully fit the structural surface of the steel structure 1 during spot-welding (as Figure 2 shown), but it does not affect its firmness and the strength of bearing the downpipe. Just ensure 2 to 3 points of spot-welding.

[0043] After the heat dissipation of the spot-welding of the nut 1 is completed, screw the stud with half of the pipe clamp 3 into the nut 1. The pipe clamp 3 protrudes about 3 cm from the wall surface. The distance between the external wall downpipe and the external wall finish is not less than 3 cm and not more than 4 cm. However, during the installation process of the downpipe, fine adjustment is still required to make the installation of the downpipe meet the acceptance standards and be straightened as a whole.

[0044] Whether it is a water receiving funnel 4 or a straight pipe below the gutter, first install the water receiving funnel 4 with the pre-set guide rope 6. At the water receiving funnel 4, use a single-head full-thread long bolt 5 to pass through directly as the guide rope support. After screwing on the nut and fixing it, sealant can be applied around the penetration hole. Two limit nuts are screwed in the middle of the bolt 5 for binding and limiting the guide rope 6 (as Figure 3As shown). The diversion rope 6 is made of a material that is light in weight, non-absorbent, and resistant to sunlight, such as a plastic rope. During the installation process, first coil up the diversion rope 6, and thread it down while installing the downspout 7 section by section. Between the sections of the downspout 7, install corrugated short joints 8 made of the same material. The corrugated short joints 8 are installed in an upper-sleeve and lower-penetrating mode. To ensure no water leakage during the process, at the upper position, it can be tightened with sealant and binding straps 9. The upper and lower penetrating sections can be appropriately longer to ensure that rainwater does not overflow. If the corrugated short joint 8 is damaged, it is also convenient to replace. Before installation, the inclination of the structure surface can be measured, and the overall inclination of the downspout 7 can be adjusted according to the degree of inclination to ensure that the pipe is as close to the wall as possible.

[0045] During the entire installation process of the downspout, refer to the position of the vertical limit rope (as an auxiliary) to ensure that the overall downspout 7 is as vertical as possible. At the position close to the ground, no diversion elbow is set for the downspout 7. Instead, a white cloth tube 10 of the same color as the downspout can be sleeved. The lower end is close to the ground. The setting method of the cloth tube 10 is similar to that of the upper mouth of the corrugated short joint 8, and it only needs to be firmly tied. At the center of the ground corresponding to the downspout opening, set a ground hook 11 to tie and fix the diversion rope 6 inside the pipe. The tightness should be appropriate to avoid applying excessive pulling force on the water bucket 4 and the diversion rope support. At the same time, a thick layer of asphalt waterproof paint can be applied to the scattered water surface around the outlet to reduce the erosion of the ground by the rainwater falling inside the downspout 7 and also ensure beauty and practicality. After the installation is completed, the overall downspout system is as Figure 1 shown.

[0046] The utility model realizes the firm installation, convenient replacement, and long service life of the downspout through the secondary vertical adjustment and straightening of the building downspout, soft connection between pipe sections, and accompanied by a diversion device inside the pipe. The utility model has been applied to the downspout projects of the steel structure workshop (40m) in the monohydrate soda crystallization section and the multi-story steel structure building (34m) in the monohydrate soda drying section of the Kazan soda processing project in Turkey.

[0047] The scope of protection required by the utility model is not limited to the above specific embodiments. For those skilled in the art, the utility model can have various deformations and modifications. Any modification, improvement, and equivalent replacement made within the concept and principle of the utility model should be included within the scope of protection of the utility model.
