[0002] In modern building structures, the roof structure is an important component of the building structure. The roof layer structure is mainly arranged on the top of the main body of the building, and plays the role of waterproofing, heat preservation and maintaining structural integrity. The commonly used roof layers are mainly divided into flat roof, sloped surface and curved surface structures. The more common roof structure in modern buildings is the flat roof structure.

[0003] At present, the roof structure usually adopts a multi-layer structure in order to meet the requirements of waterproofing, windproofing, heat preservation and structural strength. According to the common inverted roof structure, it is divided into several structures including concrete structure layer, leveling layer, waterproof layer and thermal insulation layer. Therefore, during the construction process, different construction processes are required according to different layers. The bonding between the layers of this structure is weak.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-12 The present invention provides an implementation scheme: In the roof structure of modern buildings, most flat roof layers are cast with concrete. However, this concrete roof covering structure has the following problems during application: the covering is divided into multiple layers, and the construction process of each layer is different, so the construction period is long, and due to the different construction processes of the multi-layer structure, the bonding between the layers is poor, which easily causes damage to the roof structure.

[0051] Embodiment 1: In view of the above problems, according to the attached Figure 1 -Attached Figure 4It can be seen that the present application discloses a roof covering layer structure, which is designed for a flat roof structure. Specifically, the roof structure layer 1 is based on the roof structure layer 1. The roof structure layer 1 is cast with concrete and is the main body of the top structure of the house. At the same time, a plurality of connecting bars 11 arranged in a matrix are pre-embedded in the roof structure layer 1. The bottoms of the plurality of connecting bars 11 are laid in the roof structure layer 1 with a steel grid structure. A leveling layer 2 is laid on the upper layer of the roof structure layer 1. The leveling layer 2 is used to level the roof surface layer. The leveling layer 2 is a cement mortar layer. The horizontal slope of the leveling layer 2 is between 5° and 10°, and the thickness of the leveling layer 2 is between 30-40 mm. A prefabricated covering layer 3 is arranged on the leveling layer 2. In order to improve the construction efficiency, the prefabricated covering layer 3 is prefabricated in advance. During construction, the prefabricated covering layer 3 is directly laid so that the prefabricated covering layer 3 covers the top of the house. The prefabricated covering layer 3 is prefabricated in multiple layers to play a waterproof and heat-insulating role.

[0052] According to the instruction manual Figure 1 -Attached Figure 4 It can be known that the above-mentioned prefabricated covering layer 3 includes a pair of waterproof roll material layers 31, the pair of waterproof roll material layers 31 are a pair of self-adhesive rubber asphalt waterproof roll materials, the thickness of the pair of waterproof roll material layers 31 is not less than 2mm, and the inner side of the pair of waterproof roll material layers 31 is compounded with a pair of rubber reinforcement layers with a thickness of not less than 5mm, a skeleton layer is arranged between the pair of waterproof roll material layers 31, and a foam insulation layer 32 is filled between the pair of waterproof roll material layers 31. The pair of waterproof roll material layers 31 are the upper and lower closing devices of the prefabricated covering layer 3, and the skeleton layer arranged between the pair of waterproof roll material layers 31 plays a role in supporting the pair of waterproof roll material layers 31. The foam insulation layer 32 is close to the upper waterproof roll material layer 31, and the foam insulation layer 32 is an insulation attachment layer of extruded polystyrene material with a thickness between 30mm-40mm;

[0053] Furthermore, a pair of lower waterproof coiled material layers 31 are provided with a plurality of fixing holes, a plurality of embedded sleeves 33 are embedded in the plurality of fixing holes, and the plurality of embedded sleeves 33 are sleeved outside the plurality of connecting ribs 11. After the plurality of connecting ribs 11 and the plurality of embedded sleeves 33 are connected, anchor points are provided for laying the prefabricated covering layer 3, thereby fixing the prefabricated covering layer 3 and preventing the prefabricated covering layer 3 from moving.

[0054] According to the instruction manual Figure 1 -Attached Figure 4It can be seen that the above-mentioned skeleton layer is composed of a plurality of embedded sleeves 33, and the skeleton layer also includes a plurality of connecting rods 34. The ends of the plurality of embedded sleeves 33 are embedded in the foam insulation layer 32. The two ends of the embedded sleeves 33 respectively support a pair of waterproof coiled material layers 31. A plurality of connecting rods 34 are arranged on the waterproof coiled material layer 31 on the upper side of the pair. The plurality of connecting rods 34 are reversely connected with the plurality of embedded sleeves 33, so that the pair of waterproof coiled material layers 31 and the foam insulation layer 32 are relatively tied together to avoid the problem of the outlet wires of the pair of waterproof coiled material layers 31 being damaged.

[0055] According to the instruction manual Figure 2 It can be seen that the above-mentioned prefabricated covering layer 3 also includes a filling groove 35. Specifically, a filling groove 35 is provided between the lower waterproof coiled material layer 31 and the foamed insulation layer 32. The filling groove 35 is used to fill cement mortar. After the prefabricated covering layer 3 is laid, a layer of cement mortar needs to be filled in the filling layer to increase the weight of the prefabricated covering layer 3 so that it is close to the leveling layer 2, and to improve the overall structural strength of the prefabricated covering layer 3.

[0056] According to the instruction manual Figure 3 -Attached Figure 4 It can be seen that a pouring pipeline is provided between the connecting rod 34 and the embedded sleeve 33, and the pouring pipeline includes a pouring inlet 341. The end of the connecting rod 34 is provided with a pouring inlet 341, and the pouring inlet 341 is arranged along the axial direction of the connecting rod 34. The pouring inlet 341 penetrates into the embedded sleeve 33, and a plurality of connecting holes 352 are arranged in a ring array on the embedded sleeve 33 and penetrate between a pair of waterproof coiled material layers 31;

[0057] In the specific implementation process, the pouring inlet 341 adopts a socket structure, and an intermediate hole 351 is opened on the central axis of the embedded sleeve 33 to connect with the pouring inlet 341. During pouring, cement mortar enters the intermediate hole 351 under the action of high-pressure pushing. In the intermediate hole 351, the connecting rib 11 is inserted from the bottom of the intermediate hole 351. Under the action of cement mortar, the embedded sleeve 33 and the connecting rib 11 are connected as a whole, and then the connecting hole 352 is set on the outside of the intermediate hole 351. The cement mortar enters between the foamed insulation layer 32 and the waterproof membrane layer 31 from the connecting hole 352 to fill the space between the two and play a supporting role after drying. After the pouring is completed, the pouring inlet 341 of the connecting rod 34 needs to be sealed, and the sealing material uses the same material as the waterproof membrane layer 31.

[0058] Furthermore, a 20-30 mm thick concrete protective layer 4 is laid on the top of the prefabricated covering layer 3 to seal the top and maintain the structural integrity and aesthetics of the top building roof.

[0059] It should also be noted that after the prefabricated covering layer 3 is laid, there will be a gap between the top edge of the prefabricated covering layer 3 and the side wall of the building roof. Therefore, the gap needs to be sealed with sealant, and the building inner corner and the top edge of the prefabricated covering layer 3 and the upper part of the building gap are closed with a waterproof tape. The waterproof tape is cut with the same material as the waterproof membrane layer 31 and should be a rounded structure when closed.

[0060] Embodiment 2: According to the specification sheet Figure 5 -Attached Fig.12 It can be seen that in order to construct the above-mentioned roof covering structure, the present application also discloses a roof construction tool for laying the above-mentioned roof covering structure. The construction tool matches the use of the prefabricated covering layer 3, and adopts a combination of laying and pouring to carry out roof construction. The construction tools are few and the preparation work is simple.

[0061] Specifically, after the main body of the roof is constructed, a pair of transverse tracks 5 are set up on both sides of the roof outer wall, and are fixed by scaffolding. The pair of transverse tracks 5 are arranged in parallel on the roof, and a motion control mechanism 6 is installed on the pair of transverse tracks 5, which is used as a traveling device;

[0062] Furthermore, a coil unwinding mechanism 7 is provided on the motion control mechanism 6, and the prefabricated covering layer 3 is arranged in a roll on the coil unwinding mechanism 7. As the motion control mechanism 6 drives the coil unwinding mechanism 7 to move, the prefabricated covering layer 3 is unwound at a certain linear speed, and then a coil paving structure 8 is separately connected to one side of the coil unwinding mechanism 7. The coil paving structure 8 squeezes the prefabricated covering layer 3 laid on the roof so that the prefabricated covering layer 3 is laid flat on the roof. A pouring controller 9 is also provided on the motion control mechanism 6. The pouring controller 9 is used to pour inside the prefabricated covering layer 3. The pouring controller 9 is also responsible for the pouring construction of the roof leveling layer 2 and the concrete protective layer 4.

[0063] According to the instruction manual Figure 7 -Attached Figure 8It can be seen that the coiled material paving structure 8 includes a telescopic frame 81, which is installed on the motion control mechanism 6. A telescopic adjuster 82 is provided on the telescopic frame 81. The telescopic adjuster 82 uses a screw structure to control the lifting and lowering of the telescopic frame 81, and then a hanging frame 83 is provided on the telescopic adjuster 82. The hanging frame 83 is divided into a plurality of guide grooves 84, and each guide groove 84 is correspondingly provided with a roller press 85. A pin is movably installed in the middle of the roller press 85, and the roller press 85 can rotate with the pin as the axis. By adjusting the telescopic adjuster 82, a plurality of released prefabricated covering layers 3 on the hanging frame 83 pass through the lower part of the roller press 85. Under the pressing action of the roller press 85, the prefabricated covering layer 3 is tightly covered and pasted on the leveling layer 2.

A pair of limit bearings are provided on both sides of the axial cavity and sleeved on the pin shaft. During the movement of the roller press 85, the pair of limit bearings play a role in limiting the roller press 85, thereby preventing the roller press 85 from horizontal movement and reducing the rotation resistance of the roller press 85.

[0065] According to the instruction manual Figure 7 -Attached Figure 8 It can be seen that in order to match the horizontal slope change of the leveling layer 2, a pair of lifting sliders 86 are provided at both ends of the pin shaft, and a pair of control buffers 87 are installed on the guide groove 84. The ends of the pair of control buffers 87 are connected to the pair of lifting sliders 86. The pair of lifting sliders 86 are movably matched with the two ends of the pin shaft. The pair of lifting sliders 86 and the two sides of the pin shaft respectively control the height of the pair of lifting sliders 86 through the pair of control buffers 87, thereby adjusting the position of the pair of lifting sliders 86, so that the pair of lifting sliders 86 can synchronously adjust the height of the roller press 85;

[0066] The control buffer 87 is composed of a guide rod and a guide groove 84. The guide groove 84 is set on the hanging frame 83. The guide rod is assembled in the guide groove 84. The end of the guide rod is movably connected with the hanging slider 86. The outer sleeve of the guide rod is provided with a reset spring. The two ends of the reset spring are supported between the hanging slider 86 and the guide groove 84. As the horizontal height of the leveling layer 2 changes, the reset spring expands and contracts, and the guide rod moves in the guide groove 84 to keep the roller 85 always in contact with the prefabricated covering layer 3.

[0067] According to the instruction manual Figure 5 -Attached Figure 6It can be known that the motion control mechanism 6 includes a pair of sliding guide blocks 61, which are assembled on a pair of transverse rails 5. The pair of sliding guide blocks 61 are laterally fixed with at least a pair of reinforcing rods by screws. A pair of transverse wheel groups 62 are arranged on one side of the transverse rail 5. A sliding control system is arranged between the pair of transverse wheel groups 62. The pair of sliding guide blocks 61 are matched with the pair of transverse rails 5. The pair of transverse rails 5 play a guiding and limiting role for the pair of sliding guide blocks 61. The movement of the sliding guide blocks 61 on the transverse rails 5 is controlled by the sliding control system between the pair of transverse wheel groups 62. The pair of sliding guide blocks 61 on the transverse rails 5 are symmetrically arranged and move synchronously, so that the pair of sliding guide blocks 61 drive the casting controller 9, the coil unwinding mechanism 7 and the coil paving structure 8 to move horizontally to complete laying and casting.

[0069] During the specific implementation process, the sliding control motor 63 drives the gear box 64 to rotate, so that the gear box 64 drives the transverse shifting wheel group 62 on one side to rotate, and a pair of transverse shifting wheel groups 62 and the transmission belt 65 form a belt drive, and then the pair of transverse shifting wheel groups 62 drive the transverse connecting block 66 to move. The transverse connecting block 66 is fixedly connected to the slot by bolts, so that the transverse connecting block 66 synchronously drives the sliding guide block 61 to move during the movement.

[0071] In the specific implementation process, the support roller 71 is used to place and support the material roll of the prefabricated covering layer 3. One end of the support roller 71 is controlled by the reel-in assembly 72. The reel-in assembly 72 controls the rotation of the support roller 71, so that the support roller 71 drives the prefabricated covering layer 3 to rotate to complete the reeling and unreeling of the material roll. A disassembly assembly 73 is provided at the end of the support roller 71 for installing and fixing the support roller 71.

[0072] According to the instruction manual Fig. 9 -Attached Fig.10 It can be known that the above-mentioned winding and unwinding assembly 72 includes a rotating shaft tube 721, which is installed on the sliding guide block 61, and the rotating shaft tube 721 and the sliding guide block 61 are movably matched.

One end of the support roller 71 is inserted into the rotating shaft tube 721, and the rotating shaft tube 721 and the end of the support roller 71 are limited by the shaft key. One side of the rotating shaft tube 721 is connected to the winding and unwinding motor 722, and the winding and unwinding motor 722 controls the rotation of the rotating shaft tube 721 through the gear set 723;

[0073] During the specific implementation process, the rotating shaft tube 721 cooperates with the rotating groove, and an opening on one side of the rotating shaft tube 721 is used to insert the support roller 71.
