DETAILED DESCRIPTION

[0035] The embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0036] As shown in Figure 1 , the outer wall waterproof roll construction device provided by the embodiments of the present application is applied to the waterproof roll laying of the basement outer wall, and the outer wall waterproof roll construction device comprises a main frame body 3, a laying mechanism 4, a compaction mechanism 5 and a power mechanism 6. The main frame body 3 is arranged at intervals with the basement outer wall 2, and the compaction mechanism 5 and the laying mechanism 4 are both located between the main frame body 3 and the basement outer wall 2. The output end of the power mechanism 6 is connected with the laying mechanism 4, and the power mechanism 6 can drive the laying mechanism 4 to ascend and descend along the height direction of the basement outer wall 2. The laying mechanism 4 comprises a roll mounting roller 14 for mounting the waterproof roll 8 and a bonding assembly 7, and the laying mechanism 4 can unfold and lay the waterproof roll on the basement outer wall 2. The compaction mechanism 5 is located at the lower side of the laying mechanism 4, one end of the compaction mechanism 5 extends to the basement outer wall 2, and the other end of the compaction mechanism 5 is slidably connected with the main frame body 3, and the compaction mechanism 5 can compact the waterproof roll 8 on the basement outer wall 2. Thus, the outer wall waterproof roll construction device can lay the waterproof roll 8 on the basement outer wall 2, and manual laying is not needed, the construction cost is lower, the efficiency is higher, the quality is ensured, and the safety hidden danger is reduced.

[0037] With the development and construction of cities, land resources are increasingly scarce, and public buildings are inevitably extended to underground space. In the construction process of underground space, a foundation pit 1 is first processed, and a foundation pit support structure and a basement structure are constructed in the foundation pit 1. After the basement outer wall 2 is formed, the waterproof roll 8 is laid on the outer wall thereof, and a certain space is reserved outside the basement outer wall 2 to provide a processing space for laying the waterproof roll 8.

[0038] As shown in Figure 1 , Figure 2 , and Figure 4As shown, the main frame body 3 comprises a column 13, a cantilever 15 and a guide rail 25, wherein the column 13 has two, two columns 13 are erected and arranged at intervals in the length direction of the basement outer wall 2, and the two columns 13 are fixed as a whole by connecting ribs (not shown in the figure). The two columns 13 are consistent in shape and size, both of which are C-shaped steel, that is, the cross section is C-shaped, so that each column 13 encloses a slide 20 extending in the height direction (vertical direction) of the basement outer wall 2, and the open side of the slide 20 faces the basement outer wall 2. The column 13 is not limited to C-shaped steel, for example, U-shaped steel, which has a U-shaped cross section, also makes each column 13 enclose a slide 20 extending in the height direction (vertical direction) of the basement outer wall 2. The top of each column 13 is provided with a cantilever 15, one end of the cantilever 15 is connected with the column 13 and perpendicular to the column 13, forming a right angle type, and the cantilever 15 also uses the same steel as the column 13, for example, C-shaped steel. The guide rail 25 is arranged at the bottom of the foundation pit 1 and extends in the length direction of the basement outer wall 2, and the distance from the guide rail 25 to the basement outer wall 2 matches the pressing mechanism 5. Among them, the guide rail 25 is U-shaped, which encloses a mounting groove 26, and the bottom of the above-mentioned column 13 is inserted into the guide rail 25, which can guide the two columns 13 to move in the length direction of the basement outer wall 2 under the premise of limiting the distance between the column 13 and the basement outer wall 2, so that the displacement of the main frame body 3 is more convenient. In addition, the bottom of each column 13 is provided with a first roller 24, which is in the above-mentioned guide rail 25 and can roll in the guide rail 25, further improving the convenience of column 13 sliding.

[0039] As Figure 1 , Figure 2 and Figure 5As shown, the pressing mechanism 5 is horizontally arranged, one end of which presses the waterproofing sheet 8 spread on the ground and is in contact with the outer wall 2 of the basement, and the other end is connected with the main frame 3, so that the pressing mechanism 5 is clamped between the main frame 3 and the outer wall 2 of the basement. The pressing mechanism 5 comprises a pressing roller shaft 9 and a support frame 10, wherein the support frame 10 extends perpendicularly to the column 13 and towards the outer wall 2 of the basement, one end of the support frame 10 is provided with a roller mechanism 18, and the other end is provided with the pressing roller shaft 9. The support frame 10 comprises a reinforcing arm 17 and two spaced support arms 16, the two support arms 16 are identical in size and parallel to each other, and the two support arms 16 are spaced apart in the extension direction of the outer wall 2 of the basement. The pressing roller shaft 9 is located between the two support arms 16 and at the same end of the two support arms 16, and the pressing roller shaft 9 is rotatably connected with the support arms 16, which can freely rotate around its own axis, so that the pressing roller shaft 9 can roll on the outer surface of the outer wall 2 of the basement. In addition, the reinforcing arm 17 is two intersecting angle steels, the two ends of which are respectively connected with the two support arms 16, so that the two support arms 16 are integrated and the relative positions of the two support arms 16 are maintained. The support frame 10 is provided with the roller mechanism 18 away from the pressing roller shaft 9, wherein the roller mechanism 18 is two roller sets 19, and the two roller sets 19 correspond to the two support arms 16 one by one, and the two roller sets 19 correspond to the slide 20 on the two columns 13 respectively, the roller set 19 rolls along the extension direction (i.e. the vertical direction) of the slide 20, realizing the sliding connection between the pressing mechanism 5 and the main frame 3.

[0040] As shown in Figure 1 , Figure 3 and Figure 8 , the waterproofing sheet 8 in the form of a roll is wound on the sheet mounting roller 14, and the sheet mounting roller 14 is rotatably connected with the mounting seat 28, and the waterproofing sheet 8 is rotated during the process of being pulled and spread. The mounting seat 28 has a taper sleeve, the sheet mounting roller 14 can be pulled out of the mounting seat 28, and the taper sleeve has a bolt assembly outside to prevent the taper sleeve from moving outward, but is not limited to the bolt assembly, for example, a latch can be used to limit the movement of the taper sleeve.

[0041] As shown in Figure 1 , Figure 3 and Figure 5As shown, the adhesive assembly 7 is a glue storage and spraying module, which includes a glue storage tank 21 for storing glue and a spraying head 22 at the bottom of the glue storage tank 21. The glue storage tank 21 is directly above the roll mounting roller 14, and the spraying head 22 is a linear spraying head, which is provided with multiple nozzles for uniform spraying in a certain area. Compared with a single-point spraying head, the glue sprayed by the linear spraying head is more uniform and has a certain width, which ensures that the spraying area is large and uniform and improves the adhesive quality. The spraying head 22 is located at the bottom of the glue storage tank 21 and is close to one side of the basement outer wall 2. In this way, the glue will not flow away from the basement outer wall 2. In addition, the spraying head 22 extends downward and maintains a reasonable distance from the roll, avoiding the problem of glue splashing due to too far a distance. The spraying head 22 can be controlled to uniformly spray the adhesive onto the roll mounting roller 14, and the waterproof roll 8 on the roll mounting roller 14 is uniformly coated with glue. The surface of the waterproof roll 8 that is sprayed with glue is the surface that is attached to the basement outer wall 2. The glue storage tank 21 is connected to the mounting seat 28 through a first connecting member 27, and the roll mounting roller 14 is rotatably connected to the mounting seat 28. This ensures that the relative position of the adhesive assembly 7 and the roll mounting roller 14 is fixed, which is beneficial for the synchronous lifting of the two. In addition, the laying mechanism 4 also has a guide roller 23, which is arranged on the side of the roll mounting roller 14 close to the basement outer wall 2. The distance between the guide roller 23 and the basement outer wall 2 is slightly greater than the thickness of the waterproof roll 8. The unwound waterproof roll 8 extends from the roll mounting roller 14 to the guide roller 23 and then to the bottom of the basement outer wall 2. The guide roller 23 provides guidance and also presses the waterproof roll 8 to the side of the basement outer wall, so that it is initially attached to the surface of the basement outer wall 2.

[0042] In some example embodiments, the adhesive assembly 7 can also be a fuel storage and combustion flame spraying module, which includes a fuel tank for storing fuel and a flame spraying member at the bottom of the fuel tank. The flame spraying member can ignite the fuel and direct the flame towards the roll mounting roller 14. After the waterproof roll 8 on the roll mounting roller 14 is heated, it becomes sticky and adheres to the basement outer wall 2 as it is unwound and attached to the basement outer wall 2, achieving fixation on the basement outer wall 2.

[0043] In some example embodiments, as shown in Figure 5 The pressing mechanism 5 is connected to the laying mechanism 4, and the support arm 16 is connected to the mounting seat 28 through a third connecting member 29. Based on the relative fixation of the adhesive assembly 7 and the roll mounting roller 14, the position of the pressing mechanism 5 and the laying mechanism 4 is also relatively fixed. In addition, the third connecting member 29 and the roll mounting roller 14 on the mounting seat 28 are not coaxially arranged, which is beneficial for the taking and placing of the roll mounting roller 14.

[0044] In some example embodiments, the power mechanism 6 is on the top of the main frame 3, wherein the power mechanism 6 is on the cantilever 15, the first pulley 11 is also hung on the cantilever 15, the output end of the power mechanism 6 is connected with the pull rope 12, one end of the pull rope 12 is wound on the power mechanism 6, and the other end of the pull rope 12 is wound around the first pulley 11 and extends downward and is connected with the bonding assembly 7. Thus, the power mechanism 6 can pull the pull rope 12 to gradually make it be recovered on the power mechanism 6, shorten the effective length of the pull rope 12, and the laying mechanism 4 and the compacting mechanism 5 are pulled to ascend gradually in the process.

[0045] In some example embodiments, as shown in Figure 9 the power mechanism 6 is on the main frame 3, wherein the bottom of the power mechanism 6 has wheels, which are placed on the bottom surface to facilitate the movement, and the output end of the power mechanism 6 is connected with the pull rope 12 to drive the lifting. In addition, the output end of the power mechanism 6 can also be connected with the main frame 3 to provide power for the movement of the main frame 3, which is more efficient and convenient to operate.

[0046] In some example embodiments, as shown in Figure 6 and Figure 7 the compacting mechanism 5 has no connection relationship with the laying mechanism 4, and the power mechanism 6 is connected with the laying mechanism 4 through the flexible pull rope 12.

[0047] In some example embodiments, as shown in Figure 6 and Figure 7 the laying mechanism 4 is connected with the power mechanism 6 through one pull rope, and the compacting mechanism 5 is connected with the output end of the power mechanism 6 through another pull rope 12, the second pulley 30 is also hung on the cantilever 15, and the pull rope 12 acting on the compacting mechanism 5 is wound around the second pulley 30 and connected to the power mechanism 6. After the power mechanism 6 is turned on, the two pull ropes can be pulled to ascend synchronously, so that the compacting mechanism 5 and the laying mechanism 4 also ascend synchronously.

[0048] In some example embodiments, the support arm 16 is a telescopic mechanical arm 31, which can be telescopic along the length direction, and the compacting mechanism 5 further comprises a telescopic driving module (not shown in the figure), the output end of the telescopic driving module is connected with the mechanical arm 31, so as to drive the mechanical arm 31 to be telescopic. When the mechanical arm 31 is shortened, the compacting roller shaft 9 can provide space for the further downward movement of the laying mechanism 4, and the compacting mechanism 5 no longer interferes with the laying mechanism 4 in the vertical direction.

[0049] In the construction of the outer wall waterproofing membrane construction device, first, the device is erected, and the laying is prepared. Then, the laying mechanism 4 is lowered to the lowest position, one end of the waterproofing membrane 8 is manually laid flat on the surface of the basement outer wall 2, and the one end of the waterproofing membrane 8 is fixed at the bottom position of the basement outer wall 2. Then, the glue spraying and lifting are started, the nozzle 22 sprays the adhesive, and the power mechanism 6 pulls the laying mechanism 4 and the pressing mechanism 5 to lift synchronously. At this time, since the one end of the waterproofing membrane 8 is positioned at the bottom of the waterproofing membrane 8, the waterproofing membrane 8 is pulled to expand and is attached to the surface of the basement outer wall 2 under the guidance of the guide roller, but not closely attached. The pressing mechanism 5 further processes the waterproofing membrane 8, i.e. extrudes the waterproofing membrane 8 preliminarily attached to the surface of the basement outer wall 2, so that it is completely attached. Thus, the laying mechanism 4 and the pressing mechanism 5 are moved to the highest position, forming the laying process of the waterproofing membrane 8 from bottom to top. The basement outer wall 2 at the corresponding position of the main frame body 3 has been completely laid with the waterproofing membrane. Then, the stand column 13 is moved along the guide rail to the position where the waterproofing membrane 8 is not laid, and the above steps are continued to lay the waterproofing membrane 8 until the laying of the waterproofing membrane 8 is completed on all positions of the basement outer wall 2.

[0050] In combination with the above embodiment, the outer wall waterproofing membrane construction device of the embodiment of the present application saves the manual laying operation, which not only saves manpower and improves efficiency, but also makes the construction cost lower, the efficiency higher, the quality improved, and the safety hidden danger relatively reduced.
