DETAILED DESCRIPTION

[0032] The technical scheme in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0033] As shown in Figures 1 to 3 The first aspect of the present application provides a hard foam polyurethane and waterproof board integrated fixing structure, comprising: a waterproof board 1 laid on the inner wall surface of a tunnel;

[0034] An I-shaped fixed clamp 2 is arranged on the surface of the waterproof board 1, which is used to control the spraying thickness of the hard foam polyurethane layer 3.

[0035] The hard foam polyurethane layer 3 is sprayed on the surface of the waterproof board 1, covering the I-shaped fixed clamp 2.

[0036] In the embodiment, the waterproof plate 1 is laid on the inner wall of the tunnel by using hot-melt pads at the beginning of construction, and after the surface of the laid waterproof plate 1 is cleaned, plastic work type fixing fixtures 2 are constructed, the height of the plastic work type fixing fixtures 2 is just the thickness of the thermal insulation spraying, the plastic work type fixing fixtures 2 are welded on the outer side of the waterproof plate 1 at the position of the hot-melt pads by using an ultrasonic welding gun, the adhesion of the hot-melt pads is fully utilized, and the plastic work type fixing fixtures 2 are arranged at a distance of twice the distance between the hot-melt pads on the waterproof plate 1;

[0037] The number of plastic nails on each waterproof plate 1 is arranged according to the principle of one every other hot-melt pad on the waterproof plate 1, and the work type fixing fixtures 2 are used to detect whether the spraying thickness meets the standard, so that the adhesion effect of the thermal insulation layer and the waterproof layer is enhanced, and the spraying thickness of the thermal insulation layer is controlled;

[0038] When the polyurethane thermal insulation layer is sprayed, a spraying process from left to right and from bottom to top is adopted, the spraying thickness of each layer is controlled to be 0.6cm-1cm, and the design thickness is achieved by 5-8 times of layer-by-layer spraying;

[0039] By using a high-pressure airless spraying device, the pressure generated by an air compressor is used to make the sprayed liquid form a mist and quickly react and harden, so that the liquid is bonded with the waterproof plate 1 to form an integral whole, and the purposes of waterproofing, moisture-proofing and decoration are achieved;

[0040] A multi-layer spraying method is adopted, a 0.5mm bottom layer is first sprayed, and then each layer is continuously sprayed, and the thickness of each spraying is preferably 5-10mm, so that the polyurethane foam forms multi-layer foam, the thermal insulation effect is better, the polyurethane foam has higher strength, and the polyurethane foam will not be broken or detached, and after the polyurethane thermal insulation layer is fully cured for 24-48h, subsequent construction is performed;

[0041] In order to ensure the lap width of the subsequent waterproof plate 1 construction, the spraying area needs to be determined by wire laying before the spraying construction, and the non-spraying area is covered by using the leftover material of the waterproof plate 1, and the polyurethane exceeding the spraying area needs to be removed after the spraying construction is completed.

[0042] As shown in Figures 4 to 7 The second aspect of the utility model provides a kind of construction tool of hard foam polyurethane and waterproof plate integrated fixed structure, it is applied to the cleaning of waterproof plate 1 in above-mentioned one kind of hard foam polyurethane and waterproof plate integrated fixed structure, comprising:

[0043] First trowel frame 4 and second trowel frame 5, first trowel frame 4 and second trowel frame 5 are set up between each other and can be opened and closed, the rear end of first trowel frame 4 is rotatably connected with the rear end of second trowel frame 5, and the front end of first trowel frame 4 and second trowel frame 5 is provided with rotating roller 6, and first trowel frame 4 and second trowel frame 5 can flatten the wrinkles of waterproof plate 1 by unfolding mode;

[0044] The first connecting plate 7 is installed on the rotating shaft at the rear end of the second trowel 5.

[0045] The connecting rod 8 is slidably arranged on the first connecting plate 7 and can slide along the length direction of the tunnel.

[0046] The cleaning structure 9 is installed on the connecting rod 8 and can slide along the length direction of the tunnel and clean the surface of the waterproof board 1 within the range after the first trowel 4 and the second trowel 5 are unfolded.

[0047] In this embodiment, when starting cleaning, the first trowel 4 and the second trowel 5 are first closed to the waterproof board 1, the rotating roller 6 at the front end of the first trowel 4 and the second trowel 5 is pressed against the surface of the waterproof board 1, and the rotating shaft at the rear end of the second trowel 5 is pushed to unfold the first trowel 4 and the second trowel 5, effectively smoothing the wrinkles on the surface of the waterproof board 1 within the unfolded range of the first trowel 4 and the second trowel 5, improving the cleaning effect when the cleaning structure 9 is cleaned subsequently, and making the cleaning structure 9 installed on the connecting rod 8 contact the waterproof board 1, so that the cleaning structure 9 slides on the first connecting plate 7 along the length direction of the tunnel to clean the surface of the waterproof board 1 within the unfolded range of the first trowel 4 and the second trowel 5. In this way, other areas of the waterproof board 1 are cleaned in turn, which can effectively and quickly clean the entire surface of the waterproof board 1, keep the waterproof board 1 clean and dry during subsequent construction of the work type fixing clamp 2 and the sprayed hard polyurethane layer 3, and improve the construction precision.

[0048] The cleaning structure 9 comprises a rubber sheet 9-1 arranged on the side of the connecting rod 8 facing the waterproof board 1, and a cleaning cloth is arranged at the front end of the rubber sheet 9-1 for cleaning the surface of the waterproof board 1.

[0049] A first through slot 10 is formed in the first connecting plate 7, and one end of the connecting rod 8 facing the waterproof board 1 penetrates through the first through slot 10 and is fixedly connected with an arc-shaped push plate 11, which can contact the rubber sheet 9-1 to make the rubber sheet 9-1 form a shape that can fit the waterproof board 1, so as to facilitate the cleaning cloth at the front end of the rubber sheet 9-1 to clean the surface of the waterproof board 1.

[0050] In this embodiment, the rubber sheet 9-1 is made of soft material, and the arc-shaped push plate 11 can effectively make the rubber sheet 9-1 adapt to the shape of the waterproof board 1, so that the cleaning cloth at the front end of the rubber sheet 9-1 can closely contact the surface of the waterproof board 1, further improving the cleaning effect of the cleaning cloth.

[0051] The cleaning structure 9 further comprises two T-shaped mounting plates 9-2 fixedly arranged at the upper and lower ends of the rubber sheet 9-1.

[0052] The vertical plate 9-3 is installed at the end of the connecting rod 8 away from the rubber sheet 9-1, and extends to the opposite sides of the two T-shaped mounting plates 9-2, and the elastic tube 9-4 is arranged between the vertical plate 9-3 and the two T-shaped mounting plates 9-2. When the first and second trowels 4 and 5 are unfolded, the upper and lower elastic tubes 9-4 can be in contact with the rotating rollers 6 at the front ends of the first and second trowels 4 and 5, respectively.

[0053] In this embodiment, the elastic tube 9-4 between the vertical plate 9-3 and the T-shaped mounting plate 9-2 is provided with a spring, and the rubber sheet 9-1 is initially in a vertical shape. When the surface of the waterproof plate 1 is a curved surface, the middle region of the rubber sheet 9-1 protrudes forward, and the two ends of the rubber sheet 9-1 converge towards the middle, so that the elastic tube 9-4 is stretched. At the same time, the elastic tube 9-4 can well maintain the tension of the rubber sheet 9-1 when facing different curvatures of different parts of the waterproof plate 1, so that the rubber sheet 9-1 can restore the previous vertical shape after the cleaning structure 9 is cleaned.

[0054] When the first and second trowels 4 and 5 are unfolded, the elastic tube is in contact with the rotating roller 6 at the front end of the first and second trowels 5, which can limit the unfolding angle of the first and second trowels 5, so that the first and second trowels 4 and 5 can be stably arranged on the surface of the waterproof plate 1 in an unfolded state.

[0055] The rotating shaft at the rear end of the second trowel 5 is discontinuously arranged, and the rotating shaft is provided with a rotating rod 12 at the discontinuous position. The bottom of the rotating rod 12 is fixedly connected with a fixed sleeve 13 perpendicular to the length direction of the rotating rod 12. An L-shaped tube 14 is arranged on the side of the rotating rod 12 away from the rubber sheet 9-1. A second connecting plate 15 is arranged between the vertical plate 9-3 and the rotating rod 12. The bottom transverse part of the L-shaped tube 14 passes through the fixed sleeve 13 and is fixedly connected with the second connecting plate 15. A second through slot 16 is formed in the second connecting plate 15. An extension rod 17 is fixedly connected with one end of the connecting rod 8 facing the rotating rod 12, and the extension rod 17 is slidably arranged in the second through slot 16.

[0056] In this embodiment, the connecting rod 8 is square-shaped, and the connecting rod 8 will not rotate when sliding in the first sliding slot. The cleaning structure 9 mounted on the connecting rod 8 can stably slide along the length direction of the tunnel. When the second connecting plate 15 rotates, the extension rod 17 sliding in the second through slot 16 can control the sliding of the connecting rod 8 in the first through slot 10. At the same time, the rotation of the L-shaped tube 14 can drive the second connecting plate 15 to rotate around the axis of the transverse part of the L-shaped tube 14, so as to control the sliding of the connecting rod 8 through the L-shaped tube 14, and control the sliding of the cleaning structure 9 along the length direction of the tunnel through the L-shaped tube 14, which is convenient for the operator to operate.

[0057] The first connecting plate 7 is rotationally arranged on the rotating shaft of the second trowel frame 5, and the rotating shaft of the second trowel frame 5 is provided with a first limiting block 18 capable of limiting the rotation angle of the first connecting plate 7 at both ends. The opposite sides of the two arms of the second rotating shaft are provided with a second limiting block 19 capable of limiting the inward rotation angle of the first trowel frame 4 and the second trowel frame 5.

[0058] In the embodiment, the first connecting plate 7 is rotationally arranged on the rotating shaft of the second trowel frame 5, so that when the first trowel frame 4 and the second trowel frame 5 are unfolded by being attached to the surface of the waterproof board 1, the operator can control the orientation of the cleaning structure 9 through the L-shaped pipe 14, so that the cleaning structure 9 can always face the surface of the waterproof board 1 during the unfolding process of the first trowel frame 4 and the second trowel frame 5 attached to the surface of the waterproof board 1, thereby avoiding unnecessary errors. At the same time, the first limiting block 18 limits the rotation angle of the first connecting plate 7, so as to prevent the connecting plate from being deflected to an unnecessary angle due to its own weight when the first trowel frame 4 and the second trowel frame 5 are not in contact with the waterproof board 1, which is not conducive to the operation of the operator.

[0059] The second limiting plate can control the angle between the first trowel frame 4 and the second trowel frame 5 when they are not unfolded, so that the first trowel frame 4 and the second trowel frame 5 can be better unfolded when they are close to and in contact with the waterproof board 1.

[0060] The second trowel frame 5 is fixedly provided with a handle 20 on the side away from the rubber sheet 9-1, and the two same sides of the side walls of the first trowel frame 4 and the second trowel frame 5 are provided with elastic ropes 21.

[0061] In the embodiment, the handle 20 provided on the second trowel frame 5 can be more convenient for the operator to operate during the process that the first trowel frame 4 and the second trowel frame 5 approach and contact the waterproof board 1, and the operator can control the entire device through the handle 20 and the L-shaped pipe 14.

[0062] During the unfolding process of the first trowel frame 4 and the second trowel frame 5, the initial included angle between the first trowel frame 4 and the second trowel frame 5 is small, the elastic rope 21 is not taut, and the rotating roller 6 at the front end of the first trowel frame 4 and the second trowel frame 5 can generate tension on the surface of the waterproof board 1, which is convenient for smoothing the wrinkles on the surface of the waterproof board 1. When the included angle between the first trowel frame 4 and the second trowel frame 5 becomes larger, the elastic rope 21 is taut, and the larger the included angle between the first trowel frame 4 and the second trowel frame 5, the greater the tension generated by the rotating roller 6 at the front end of the first trowel frame 4 and the second trowel frame 5 on the surface of the waterproof board 1. Therefore, the rotating roller 6 at the front end of the first trowel frame 4 and the second trowel frame 5 can generate greater tension on the surface of the waterproof board 1 when the included angle between the first trowel frame 4 and the second trowel frame 5 becomes larger, so that the first trowel frame 4 and the second trowel frame 5 can maintain tension on the waterproof board 1 from the time when they contact the waterproof board 1 to the time when they are completely unfolded, so that the first trowel frame 4 and the second trowel frame 5 can smooth the wrinkles of the waterproof board 1 during the unfolding process.

[0063] The technical scope of the utility model is not only limited to the content in the above description, and the person skilled in the art can make various deformations and modifications to the above implementation manners without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the range of the utility model.
