Description

Technical Field

[0001] This utility model belongs to the field of roof waterproofing construction, specifically relating to a flame-spraying device for laying waterproof rolls in roof gardens. Background Technology

[0002] In recent years, the concept of green building has been vigorously promoted in urban construction.

[0003] Roof gardens, as an important means of urban ecological restoration, can not only effectively alleviate the urban heat island effect, but also play a key role in rainwater management, becoming an important technological direction for sustainable urban development.

[0004] However, compared with traditional roof structures, roof greening places higher demands on waterproofing, root barrier and drainage systems. Among them, the quality of waterproof membrane laying directly affects the service life and waterproofing effect of the roof garden.

[0005] Currently, the gas-fired spray guns used in the installation of waterproof membrane for roof gardens have only one nozzle. During construction, workers need to hold the gas-fired spray gun and move it back and forth across the surface of the waterproof membrane to achieve uniform heating.

[0006] This construction method is not only labor-intensive and inefficient, but also, due to the limitations of manual operation, it is difficult to ensure the uniformity of heating of different parts of the waterproof membrane, which can easily lead to the waterproof membrane not being laid firmly and the risk of leakage.

[0007] Therefore, we propose a flame-spraying device for laying waterproof membranes in roof gardens to solve the above problems. Utility Model Content

[0008] To address the problems of high labor intensity, low work efficiency, and difficulty in ensuring uniform heating of different parts of the waterproof membrane when workers use handheld gas torches to heat it, this utility model provides a flame-spraying device for laying waterproof membranes in roof gardens.

[0009] The solution adopted by this utility model to solve its technical problem is: a flame-spraying device for laying waterproof rolls in roof gardens, including a diversion pipe, a liquefied gas tank, a pressure roller, a placement frame, two auxiliary poles and two parallel main poles, wherein the roller shafts at the front and rear ends of the pressure roller are rotatably installed at the lower ends of the two main poles.

[0010] The upper end of the auxiliary pole is welded and fixed to the main pole, and casters are installed at its lower end;

[0011] The placement rack is fixedly installed between the two main vehicle poles and the two auxiliary vehicle poles, and the liquefied gas tank is placed on top of the placement rack;

[0012] The splitter pipe is installed on the right side of the main vehicle pole via a support assembly, and a gas pipe is installed between the air inlet of the splitter pipe and the air outlet of the liquefied gas tank.

[0013] The bottom of the diversion pipe is provided with at least three installation ports, and each of the installation ports is equipped with a single-opening liquefied gas flame gun.

[0014] Preferably, the upper ends of the two main vehicle poles are fixedly installed with the same push rod.

[0015] Preferably, the placement frame includes two parallel cross braces, the two ends of which are welded and fixed to the main vehicle rod and the auxiliary vehicle rod, respectively, and two placement seats are installed on the top of the two cross braces.

[0016] Preferably, the top of the placement base has an arc-shaped groove.

[0017] Preferably, the support assembly includes two sleeves, which are respectively fitted onto the front and rear ends of the diverter pipe, and the sleeves are fixedly installed on the right side of the main vehicle pole by a fixing rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model has multiple single-opening liquefied gas torches installed at the bottom of the distribution pipe. The simultaneous operation of multiple single-opening liquefied gas torches significantly increases the heating area of ​​the waterproof membrane. It eliminates the need for workers to hold the torch and move it back and forth on the surface of the membrane. The heating coverage area is wider, which not only greatly shortens the construction time and improves the laying efficiency, but also enables more uniform heating of the waterproof membrane, avoiding the problem of uneven heating caused by the limitations of manual operation.

[0020] 2. This utility model adopts a mobile design that combines a push rod and casters, along with a pressure roller structure, which allows heating and compaction operations to be completed simultaneously during construction, reducing repetitive actions for workers. Furthermore, the liquefied gas cylinder is placed on two mounting seats, avoiding the burden of transportation and allowing manpower to be more focused on construction precision control.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1-2 This utility model provides a technical solution for a flame-spraying device for laying waterproof rolls in roof gardens:

[0026] Example 1:

[0027] according to Figure 1 and Figure 2 As shown, it includes a diversion pipe 42, a liquefied gas tank 1, a pressure roller 24, a placement frame, two auxiliary rods 22, and two parallel main rods 21. The upper ends of the two main rods 21 are fixedly installed with the same push rod 28. The roller shafts 25 at the front and rear ends of the pressure roller 24 are respectively fitted with bearings. The two bearings are respectively at the lower ends of the two main rods 21, so that the pressure roller 24 can rotate.

[0028] The upper end of the auxiliary pole 22 is welded and fixed to the main pole 21, and the lower end is equipped with casters 23. By adopting a moving design that combines a push rod 28 with casters 23, and with the structure of the pressure roller 24, heating and compaction operations can be completed simultaneously during construction, reducing repetitive actions for workers.

[0029] The placement frame is set between two main poles 21 and two auxiliary poles 22. The placement frame includes two parallel cross braces 26. The two ends of the cross braces 26 are welded and fixed to the main poles 21 and the auxiliary poles 22 respectively. The main poles 21, the auxiliary poles 22 and the cross braces 26 are welded to form a stable frame. Two placement seats 27 are installed on the top of the two cross braces 26. The top of the placement seats 27 has an arc-shaped groove. The liquefied gas tank 1 is placed on the top of the two placement seats 27 to avoid the burden of transportation and allow manpower to be more focused on construction precision control.

[0030] The diverter pipe 42 is installed on the right side of the main vehicle pole 21 via a support assembly. The support assembly includes two pipe sleeves 41, which are respectively fitted onto the front and rear ends of the diverter pipe 42. The pipe sleeves 41 are fixedly installed on the right side of the main vehicle pole 21 via a fixing rod 43 to support and fix the diverter pipe 42. A gas pipe 3 is installed between the air inlet of the diverter pipe 42 and the air outlet of the liquefied gas tank 1.

[0031] The bottom of the diversion pipe 42 is provided with at least three installation interfaces. The number of installation interfaces can be adjusted according to the width of the roll material. For example, a 30cm wide roll material uses 3 installation interfaces, and a 50cm wide roll material uses 5 installation interfaces. Each installation interface is equipped with a single-opening liquefied gas torch 44. Multiple single-opening liquefied gas torches 44 can work simultaneously, which significantly increases the heating area of ​​the waterproof roll material. Workers do not need to hold the torch and move it back and forth on the surface of the roll material. The heating coverage area is wider, which not only greatly shortens the construction time and improves the laying efficiency, but also enables more uniform heating of the waterproof roll material, avoiding the problem of uneven heating caused by the limitations of manual operation.

[0032] In practical use, the flame-spraying device for laying waterproof rolls in a roof garden according to this utility model first places the liquefied gas tank 1 on two placement seats 27, then connects the gas outlet of the liquefied gas tank 1 to the gas inlet of the diversion pipe 42 through the gas pipe 3, checks whether the interface is sealed to prevent gas leakage, and then installs the corresponding number of single-opening liquefied gas flame guns 44 (such as 3 or 5) at the bottom of the diversion pipe 42.

[0033] Move the device to the construction area, turn on the valve of the liquefied gas tank 1 and the switch of the single-open liquefied gas flame gun 44 in sequence, ignite the flame, adjust the flame size to a suitable level, operate the push rod 28 to slowly push the device, and the multiple single-open liquefied gas flame guns 44 work at the same time to ensure uniform heating. While heating, the pressure roller 24 automatically rolls with the device to press the softened waterproof membrane onto the base layer.

[0034] After the final laying is completed, first close the valve of the liquefied gas tank 1, and then close the switch of the single-open liquefied gas flame gun 44.
