Description

A kind of assembled board house building roof steel structure

Technical Field

The utility model relates to the technical field of assembled buildings, in particular to a roof steel structure of an assembled board house building.

Background technique

Prefabricated buildings divide the entire building into standardized modules, and build houses through mass production in factories and on-site installation. Among them, the steel structure of the roof of the prefabricated panel house is a relatively important part of the prefabricated building. The roof structure of the panel house is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The roof of the panel house mostly adopts an integral welded structure, and the roof is generally designed to be sloped to both sides, which can effectively prevent rainwater from accumulating on the roof. However, this type of building is relatively closed, and it is difficult to set up an insulation layer. When the strong sunlight shines on the roof for a long time in summer, the air temperature in the house rises, and the hot air is difficult to circulate out.

Based on the above problems, there is an urgent need for a top steel structure that can effectively insulate the roof of a prefabricated house building.

Utility Model Content

In view of the fact that the current steel structure of the roof of a prefabricated house building cannot effectively insulate, the utility model provides a steel structure of the roof of a prefabricated house building to solve the above problem.

In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

An embodiment of the present application discloses a steel structure for the roof of an assembled panel house building, comprising an inverted "V"-shaped top plate fixed by a support beam, wherein a plurality of rows of water collection grooves are detachably provided on the top surface of the top plate through a fixing frame, wherein the plurality of rows of water collection grooves are arranged obliquely and are interconnected, and the water collection grooves cover the top plate.

Optionally, the water collection groove is a triangular groove, and the triangular groove includes a first baffle and a second baffle, and the first baffle does not conflict with the top plate.

Optionally, a drain outlet is provided at the bottom of the fixing frame.

Optionally, the water collection tank is made of plastic.

Optionally, it also includes a water storage bucket, the volume of which is greater than the sum of the volumes of all the water storage tanks, the water storage bucket is set on the top plate and its height is higher than the water storage tanks, and a switch valve is set at the bottom of the side of the water storage bucket, and the water outlet of the switch valve faces the water storage tank set at the top.

Optionally, the switch valve is a float switch valve, the float is arranged in the water storage tank at the bottom and the tail is connected to the switch valve through a connecting rod. When the water in the water storage tank supports the float switch valve to the top, the float drives the connecting rod, and the connecting rod drives the switch valve to close the switch valve.

Optionally, the top surface of the water storage bucket is also connected to a water inlet pipe, and the water inlet pipe is also connected to an electronic water pump for replenishing the water in the water storage bucket.

The beneficial effects of the utility model are:

The utility model has a detachable fixed water collection trough on the roof of the assembled board house building through a fixing frame, and a drainage hole is arranged under the fixing frame. On the basis of ensuring the drainage of the roof, the water collection trough can collect rainwater when it rains, and water can also be actively added to the water collection trough. The rainwater in the water collection trough is equivalent to providing a heat insulation layer. The heat from the sun is absorbed by the water in the trough, and the heat dissipation speed of the water is relatively slow, and the heat will not be immediately transferred to the house.

Detailed ways

In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

Please refer to Figures 1-2. The embodiment of the present application discloses a steel structure for the roof of an assembled panel house. For example, in order to ensure good drainage of the roof and prevent rainwater from accumulating on the roof for a long time and corroding the connection between the roof baffles and causing leakage, the roof is generally designed to be a slope inclined on both sides. The accumulated water on the roof will flow down the slope due to gravity and will not accumulate on the roof. However, since the heat dissipation performance of water is relatively slow, it is a better heat insulation carrier and can be used on the roof to resist sunlight and reduce the rate of heat transfer into the house. However, rainwater accumulated on the roof for a long time will also cause the roof to be eroded by rainwater, resulting in leakage. Based on the above contradiction, we have installed a steel structure on the roof 1 through the top of the top plate 1 on the basis of the original inverted "V"-shaped top plate 1 fixed by the support beam. The fixing frame 2 is detachably provided with multiple rows of water collection grooves 3. As shown in the figure, the water collection grooves 3 can accumulate rainwater or water added by the user, and a drain port 4 is provided at the bottom of the fixing frame 2 for fixing the water collection grooves 3. This design will not cause rainwater to directly contact the roof due to the fixing frame 2 and accumulate on the roof in a direct contact manner. It is worth mentioning that the water collection grooves 3 can cover the roof to prevent the sun from directly shining on the top surface of the roof. In addition, the accumulated water in the water collection grooves 3 can absorb the heat transmitted by direct sunlight, and the heat conduction rate of water is slow, so the heat will not be immediately transferred to the house, and the temperature in the house will not be immediately increased, and the drain port 4 can prevent rainwater from accumulating in the shielding area of the fixing frame 2 and flow down along the top plate 1 through the drain port 4.

In the above embodiment, we set up multiple rows of water collection grooves 3 above the roof. The water collection grooves 3 can collect rainwater or moisture added by users. However, if the side walls of the water collection grooves 3 are parallel to the top plate 1, or the top surface is blocked, it is difficult for rainwater to flow into the water collection grooves 3 along the inclined top plate 1 or it is difficult to fall directly into the water storage tank due to gravity. Based on this, we make the water collection grooves 3 into triangular grooves, which include a first baffle 5 and a second baffle 6, wherein the first baffle 5 does not conflict with the top plate 1. This design, when there is a water leakage in the water collection grooves 3, it will cause rainwater to accumulate between the gaps between the water collection grooves 3 and the top plate 1, and there will be places where rainwater erodes the baffle connection that is prone to leakage, causing the roof to leak. It is worth mentioning that this design can achieve that when rainwater falls on the upper water collection grooves 3 and the water in the upper water collection grooves 3 is full, the rainwater will continue to flow into the water collection grooves 3 toward the bottom along the second baffle 6.

The above embodiment provides a design of a water storage tank 3, which can achieve the accumulation of water in the water storage tank 3 and provide a heat insulation effect. However, if rainwater accumulates in the tank for a long time, it may also corrode the water storage tank 3 and cause leakage, making it impossible to use it for a long time. Based on this, the water storage tank 3 is made of plastic, which can prevent long-term erosion by rainwater, such as PVC material and polycarbonate (PC) material, which can effectively prevent rainwater and microorganisms generated when rainwater accumulates for a long time from eroding the water storage tank 3.

In the above embodiment, rainwater is accumulated by designing a water storage tank 3 for heat insulation. However, when rainwater is insufficient, the previously accumulated rainwater may be quickly consumed and needs to be added manually. Moreover, if the weather is hot and dry, the water added to the water storage tank 3 will be quickly consumed and needs to be added manually many times, which is relatively troublesome. Based on the above problems, we have also designed a water storage bucket 7. The volume of the water storage bucket 7 is greater than the sum of the volumes of all the water storage tanks 3. The water storage bucket 7 is arranged on the top plate 1 and has a height higher than the location of the water storage tank 3. A switch valve 8 is arranged at the bottom of the side of the water storage bucket 7. The water outlet of the switch valve 8 faces the water storage tank 3 arranged at the top. When the water in the water storage tank 3 is consumed, it is only necessary to accumulate enough water in the water storage bucket 7 in advance, open the switch valve 8, and allow the water in the water storage tank 3 to be retained in the water storage tank 3 again. If the capacity of the water storage bucket 7 is relatively large, it is possible to provide water to the water storage tank 3 many times.

The above embodiment provides a design of a water storage bucket 7, which can prevent the water in the water storage tank 3 from being exhausted. However, adding water requires opening the switch valve 8, and it is impossible to know in real time whether the water in the water storage tank 3 has been accumulated. Based on this, we set the switch valve 8 as a float switch valve 8, and the float is set in the water storage tank 3 at the bottom and the tail is connected to the switch valve 8 through a connecting rod. When the water in the water storage tank 3 supports the float switch valve 8 to the top, the float drives the connecting rod, and the connecting rod drives the switch valve 8 to open. The shut-off valve 8 is closed. It is worth mentioning that the shut-off valve 8 is directed toward the water storage tank 3 designed at the top. After the water storage tank 3 at the top is filled with water, the water will continue to flow into the water storage tank 3 below until the water storage tank 3 at the lowest end is filled with water. When the water storage tank 3 at the bottom is filled with water, the float will float up, and the float will drive the connecting rod to move upward, and the connecting rod will drive the shut-off valve 8 to close. This design can automatically replenish water when there is a lack of water in the water tank, and will automatically close the shut-off valve 8 through the buoyancy effect only after all the water storage tanks 3 are filled with water.

In the above embodiment, a water storage bucket 7 is designed. When the water in the water storage bucket 7 is consumed, the water in the water storage bucket 7 will continue to be added to the water storage tank 3. When the water in the water storage bucket 7 is consumed, it is still necessary to add water manually, which is relatively troublesome. Based on this, we also connect a water inlet pipe to the top surface of the water storage bucket 7, and the water inlet pipe is also connected to an electronic water pump 9. When there is a lack of water in the water storage bucket 7, the water in the bottom water pipe can be pumped into the water storage bucket 7 through the electronic water pump 9 without manual addition.

Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

The present invention has been described in detail above in conjunction with the embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the embodiments described above may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail herein.
