[0001] The present invention relates to the technical field of roof construction, and in particular to an anti-pollution construction device and method for an ancient building roof structure. Background Art

[0002] In ancient building projects, roof renovation and maintenance is a vital task. Ancient building roofs not only carry the weight of history and culture, but also face various challenges brought by the natural environment, especially natural factors such as rain erosion and weathering erosion, which greatly accelerate the aging and damage of ancient building roofs. In order to ensure the integrity and safety of ancient building roofs, renovation work is particularly important.

[0003] However, in the actual construction process, how to effectively prevent environmental factors such as rain from polluting the newly repaired area has always been a major problem faced by construction workers. Traditional anti-pollution measures mostly rely on bulky shielding plates or leather paper and other materials. These materials are not only fragile and difficult to withstand the test of wind and rain, but also extremely inconvenient during installation and disassembly, greatly reducing construction efficiency. To this end, in response to this problem, the present invention proposes an anti-pollution construction device and method for ancient building roof structures. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide an anti-pollution construction device and method for the roof structure of an ancient building which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a pollution prevention construction device for the roof structure of an ancient building, comprising two vertical construction poles and a plurality of horizontal construction plates fixed between the two vertical construction poles, and also comprising a horizontal cylinder, wherein the horizontal cylinder is located below the bottom of the first horizontal construction plate installed above the vertical construction poles, a cavity is provided in the horizontal cylinder, an opening connected to the cavity is provided on the horizontal cylinder, a connecting shaft is rotatably provided on the horizontal cylinder, a rainproof shielding cloth is wound around the connecting shaft, and a counterweight rod is fixed to one end of the rainproof shielding cloth extending from the opening to the outside of the horizontal cylinder.

[0006] Preferably, the transverse cylinder is vertically corresponding to the transverse construction board, and a transverse block is connected between the bottom of the transverse cylinder and the transverse construction board.

[0007] Preferably, a pair of circular blocks located inside the cavity are fixed on the connecting shaft, a plurality of elastic strips distributed in a circumference are provided on the circular blocks, and the inner wall of the cavity is provided with a clamping groove that fits with the elastic strips.

[0009] Preferably, a pair of magnets are fixed on the transverse cylinder, the counterweight rod is made of iron, and an arc groove that fits with the surface of the magnet is provided on the transverse cylinder.

[0010] Preferably, a circular rotating block is fixed to one end of the connecting shaft corresponding to the outside of the transverse cylinder, a surface of the circular rotating block is provided with a plurality of arc-shaped notches distributed in a circumference, and pulling openings are provided at both ends of the counterweight rod.

[0011] Preferably, a plurality of equidistantly distributed circular holes are formed on the surface of the transverse cylinder, and the circular holes vertically correspond to the bottom of the connecting shaft.

[0012] Preferably, an air guide cylinder fixed to one end of the horizontal cylinder is sleeved on the connecting shaft, a plurality of blades distributed in a circle and all in contact with the inner wall of the air guide cylinder are fixed on the connecting shaft, an air guide port is connected to the lower surface of the horizontal cylinder, an air guide duct is connected to the upper surface of the horizontal cylinder, an air outlet is connected to the other end of the air guide duct for blowing air into the cavity, and a plurality of equally spaced air outlet heads are provided on a side of the air outlet duct corresponding to the connecting shaft.

[0013] Preferably, an installation groove is provided on the inner wall of the cavity, two ends of the air outlet pipe are connected between the side walls of the installation groove, and the air outlet head is located in the cavity.

[0014] The present invention also provides an anti-pollution construction method for an ancient building roof structure, comprising the following steps:

[0015] S1. Place two vertical construction poles firmly on the roof of the ancient building to ensure that they are in the right position. The construction workers enter the roof through the horizontal construction board to carry out the renovation of the tiles;

[0016] S2. When the weather condition is bad, pull the counterweight rod, pull the rainproof shelter cloth out of the opening, and unfold it to the position of the tiles that need to be shielded. Put the counterweight rod into the side of the middle beam of the roof, and use the force of the counterweight to keep the rainproof shelter cloth stable.

[0017] S3. After the construction is completed, roll the rainproof cloth back into the horizontal cylinder, regularly check the wear of the horizontal cylinder, connecting shaft, rainproof cloth and other parts, and replace or repair them in time.

[0019] 1. The present invention provides a construction platform through stable vertical construction poles and horizontal construction boards, and utilizes the ingenious cooperation of tough and durable rainproof shielding cloth with counterweight rods and connecting shafts. When the weather conditions are bad, the repaired part of the ancient building roof can be shielded, effectively avoiding rainwater from polluting the newly repaired area and ensuring the construction quality. At the same time, this method also realizes the rapid and convenient shielding, deployment and fixing of the rainproof shielding cloth. Compared with the traditional method of using bulky shielding boards or leather paper, it not only improves the construction efficiency, but also reduces the labor cost.

[0020] 2. The present invention uses the coordinated cooperation of elastic strips, snap-in grooves, magnets and counterweight rods to enable the rainproof shielding cloth to be stably stored in the cavity through a variety of fixing mechanisms when it is rolled up and wound through the connecting shaft, thereby preventing the rainproof shielding cloth from unfolding or loosening when not in use. At the same time, construction personnel can also rotate the connecting shaft and use the airflow generated by the blades to expel impurities entering the cavity, thereby avoiding the problem of wear of the rainproof shielding cloth due to contact with impurities entering the cavity when rolling up.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0033] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0034] Example 1: Reference Figure 1 and Figure 2 A pollution prevention construction device for an ancient building roof structure includes two vertical construction poles 1 and a plurality of horizontal construction plates 2 fixed between the two vertical construction poles 1, and also includes a horizontal cylinder 3, the horizontal cylinder 3 is located below the bottom of the first horizontal construction plate 2 installed above the vertical construction poles 1, a cavity 31 is provided in the horizontal cylinder 3, an opening 32 connected to the cavity 31 is provided on the horizontal cylinder 3, a connecting shaft 33 is rotatably provided on the horizontal cylinder 3, a rainproof shielding cloth 34 is wound around the connecting shaft 33, and a counterweight rod 35 is fixed to one end of the rainproof shielding cloth 34 extending from the opening 32 to the outside of the horizontal cylinder 3.

[0035] When it is necessary to renovate the tiles on the roof of the ancient building, only two vertical construction rods 1 need to be placed on the ancient building body. After ensuring that the two vertical construction rods 1 are stable and in a suitable position, the construction workers enter the roof by stepping on the horizontal construction board 2 to renovate the tiles. If the weather conditions are bad, the construction workers can pull the counterweight rod 35, pull the rainproof shielding cloth 34 wrapped around the connecting shaft 33 out of the opening 32, and unfold it to the position of the tiles that need to be covered, put the counterweight rod 35 into the roof on one side of the middle beam, and use the power of the counterweight to keep the rainproof shielding cloth 34 stable. The design can prevent rainwater from polluting the newly repaired ancient building roof, and compared with the traditional method of using bulky shielding boards or leather papers to cover the ancient building roof, not only is the material tough and durable and able to withstand a certain amount of wind and rain, but also through the clever cooperation of the counterweight rod 35 and the connecting shaft 33, it can achieve fast and convenient deployment and fixation, which not only greatly improves the construction efficiency, but also significantly reduces labor costs. More importantly, the device can fit the contour of the ancient building roof tightly, ensuring that every tile that needs to be repaired can be fully protected, effectively avoiding rainwater from polluting the newly repaired area.

[0036] It should be noted that if no shielding measures are taken when it rains, rain will directly impact the repair area, bringing some serious consequences. First, the strong scouring force of rain may easily carry away key materials such as tiles and mortar that have just been laid or repaired, causing the repair work to fall short, and even requiring more resources and time for secondary repairs, which not only increases construction costs, but also prolongs the construction period, posing a serious threat to the timely restoration and protection of the ancient building roof. Secondly, the water stains and marks left by rain on the roof, especially when impurities or pollutants are mixed in the rain, will seriously damage the beauty of the ancient building roof. The repair process of ancient buildings is very serious. If rainwater penetrates into the structural layer below the repair area, it will cause more complicated leakage problems and structural damage. These problems are not only difficult to detect, but also more difficult to repair, and often require more manpower, material and financial resources. In the long run, frequent rainwater erosion and soaking will accelerate the overall aging of the ancient building roof, shorten its service life, and bring huge challenges to the protection and inheritance of cultural heritage.

[0037] Furthermore, refer to Figure 5 and Fig. 9 The horizontal cylinder 3 is vertically corresponding to the horizontal construction board 2, ensuring that the horizontal cylinder 3 will not cause any obstacles or interference when the construction workers step on the horizontal construction board 2 to renovate the roof of the ancient building. A horizontal block 36 is connected between the horizontal cylinder 3 and the bottom of the horizontal construction board 2 to ensure that the horizontal cylinder 3 can be firmly installed under the horizontal construction board 2 through the horizontal block 36, thereby improving the stability of the horizontal cylinder 3 during use.

[0038] It should be noted that there are two main options for connection between the transverse block 36 fixed on the transverse cylinder 3 and the transverse construction board 2, and the specific choice depends on the actual use.

[0039] One way is that the cross block 36 can be directly fixed to the bottom of the cross construction board 2. This connection method is usually achieved through welding, riveting or other permanent connection techniques to ensure that a stable structural whole is formed between the cross tube 3 and the cross construction board 2. This connection method is suitable for construction scenarios that need to maintain stability for a long time, and can ensure that the cross tube 3 will not be displaced or shaken during use. Another way is that the cross block 36 and the bottom of the cross construction board 2 are removably connected with bolts. This connection method connects the cross block 36 to the cross construction board 2 through fasteners such as bolts and nuts, and has the advantages of easy installation and disassembly. When the position of the cross tube 3 needs to be adjusted or maintenance needs to be performed, the construction personnel can easily loosen the bolts and separate the cross block 36 from the cross construction board 2, thereby facilitating related operations. This connection method is suitable for scenarios where construction equipment needs to be frequently adjusted or moved.

[0040] Example 2: Reference Figure 4 and Figure 6-Figure 8 Different from the above-mentioned embodiment 1, a pair of circular blocks 37 located inside the cavity 31 are fixed on the connecting shaft 33, and a plurality of elastic strips 38 distributed in a circumference are provided on the circular block 37. The inner wall of the cavity 31 is provided with a snap-in groove 39 that fits with the elastic strip 38. The elastic strip 38 is made of plastic, and both the elastic strip 38 and the snap-in groove 39 are semicircular structures.

[0041] Such a technical solution is adopted to facilitate the storage of the rainproof shielding cloth 34 stably in the cavity 31 when it is stored. When the connecting shaft 33 drives the rainproof shielding cloth 34 to wrap around the connecting shaft 33, the connecting shaft 33 will also drive the elastic strip 38 on the circular block 37 to be clamped in the corresponding clamping groove 39 on the inner wall of the cavity 31. This design effectively prevents the rainproof shielding cloth 34 from loosening during the winding process, thereby ensuring the stable storage state of the rainproof shielding cloth 34.

[0042] Example 3: Reference Fig. 9 , which is different from the above-mentioned embodiments 1 and 2, a pair of magnets 310 are fixed on the horizontal cylinder 3, the counterweight rod 35 is made of iron, an arc groove 311 is provided on the horizontal cylinder 3 to fit the surface of the magnet 310, a circular rotating block 312 is fixed to the corresponding end of the connecting shaft 33 located outside the horizontal cylinder 3, a plurality of arc notches 313 distributed in a circle are provided on the surface of the circular rotating block 312, and pulling openings 321 are provided at both ends of the counterweight rod 35.

[0043] In the above technical solution, when the rainproof shielding cloth 34 is completely retracted into the cavity 31, the iron counterweight rod 35 is adsorbed on the magnet 310 on the horizontal cylinder 3 to prevent the counterweight rod 35 from causing the rainproof shielding cloth 34 to fall due to its own gravity. This design further improves the stability of the rainproof shielding cloth 34 stored in the cavity 31.

[0044] Example 4: Reference Figure 8 , which is different from the above-mentioned embodiments 1, 2 and 3, a plurality of equally spaced circular holes 322 are provided on the surface of the horizontal cylinder 3, and the circular holes 322 vertically correspond to the bottom of the connecting shaft 33, so that rainwater or fine impurities entering the cavity 31 can be discharged, avoiding affecting the storage of the rainproof shielding cloth 34 in the cavity 31 and causing wear problems.

[0045] Further optimization is to refer to Figure 7 and Figure 8 An air guide cylinder 314 fixed to one end of the horizontal cylinder 3 is sleeved on the connecting shaft 33, and a plurality of blades 315 distributed in a circle and all in contact with the inner wall of the air guide cylinder 314 are fixed on the connecting shaft 33. An air guide port 316 is connected to the lower surface of the horizontal cylinder 3, and an air guide pipe 317 is connected to the upper surface of the horizontal cylinder 3. The other end of the air guide pipe 317 is connected to an air outlet pipe 318 for blowing air into the cavity 31. The air outlet pipe 318 is located on a side corresponding to the connecting shaft 33 and is provided with a plurality of equidistantly distributed air outlet heads 319. A mounting groove 320 is provided on the inner wall of the cavity 31. Both ends of the air outlet pipe 318 are connected between the side walls of the mounting groove 320, and the air outlet heads 319 are located in the cavity 31.

[0046] By adopting such a technical solution, the blades 315 can be driven to slide along the inner wall of the air guide tube 314 with the help of the power of the rotation of the connecting shaft 33, thereby generating an airflow. The airflow enters the air guide tube 314 from the air guide port 316, and is then introduced into the air outlet pipe 318 through the air guide pipe 317. Finally, the gas is evenly blown into the cavity 31 from the air outlet head 319 entering the air outlet pipe 318. Such a design, on the one hand, can quickly dry the inner surface of the cavity 31 and the connecting shaft 33, especially in a humid environment, and effectively prevent corrosion and damage. On the other hand, during the blowing process, the gas can also quickly bring out the dust and fine impurities in the cavity 31 and discharge them through the circular hole 322, thereby avoiding the problem of wear of the rainproof shielding cloth 34 due to contact with these impurities when it is rolled up.

[0047] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
