Description

Technical Field

[0001] The utility model belongs to the technical field of modular buildings, and in particular relates to a modular roof structure. Background Art

[0002] Modular houses are increasingly widely used due to their simple structure, light materials, easy assembly and low cost. Existing modular house roofs are installed using finished roofs or prefabricated roof parts before on-site installation.

[0003] The Chinese patent with the publication number CN219548173U discloses a modular building roof structure, including a roof keel, a roof module is laid on the top of the roof keel, a groove is opened at the edge of the top of the roof module, a clamp is clamped on the inner side of the groove, and a plurality of convex plates are fixedly connected on the outer vertical surface of the clamp. The scheme improves the waterproof ability between the roof modules through the coordinated arrangement of the roof module, the groove, the clamp, the convex plate and the filling layer. The multiple convex plate structures inclined upward cooperate with the filling layer to play a good waterproof role between the roof modules. During construction, the two roof modules are squeezed against each other, squeezing the filling layer so that the convex plate penetrates into the filling layer. Water can only leak through the gaps between the multiple convex plates and the filling layer. The arrangement of the convex plate and the clamp makes the gaps between the two roof modules and the filling layer not vertical, but multi-bend, so that it is not easy for water to penetrate when rainwater leaks.

[0004] However, in actual use, when the roof module is damaged, the roof modules abut against each other, causing the inner roof module to be unable to move, and the roof module cannot be directly removed due to the restriction of the clamps. The convex plates of the clamps are inclined and penetrate into the filling layer, resulting in that after the waterproof covering is removed, the roof modules cannot be moved and the filling layer cannot be removed from the two roof modules. As a result, when the inner roof formwork is to be replaced and repaired, the outer roof formwork needs to be removed to make way for the inner roof formwork. That is, the above scheme is not conducive to the subsequent maintenance of the roof modules. Utility Model Content

[0005] The utility model is intended to provide a modular roof structure to solve the problem mentioned above that the prior art is not conducive to subsequent maintenance of the roof modules.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular roof structure, comprising

[0007] A keel frame, on which a limit strip is arranged;

[0008] The roof module is installed on the keel frame and abuts against the limit strip. Both sides of the roof module are provided with a card interface and a card connection slot with a bottom lower than the card interface. The card connection slot is connected to the card interface, and the top edge of the limit strip is lower than the top edge of the card interface.

[0009] The clamping plate has an inverted mountain shape, is installed on the roof module, and the side wall of the clamping plate is inserted into the clamping groove, and the bottom edge of the middle part of the clamping plate abuts against the top of the limit strip;

[0010] Waterproof covering, laid on roof modules and snap-on panels.

[0011] The principle and effect of this technical solution:

[0012] 1. By setting the limit strips, the roof module can be clamped through the limit strips during installation, thereby achieving initial limit, thereby preventing the roof module from sliding off the keel frame before being fixed, thereby improving safety and facilitating the installation of the roof module. The waterproof coating can improve the waterproof ability of the roof structure.

[0013] 2. Through the cooperation between the snap-in plate and the snap-in groove, the flat seam between the snap-in plate and the snap-in groove is transformed from a vertical seam to a serpentine gap, which makes it difficult for rainwater to penetrate through the gap, thereby improving the waterproof ability. By disassembling and assembling the snap-in plate, the limit of the snap-in plate on the keel frame can be released, so that when the roof module is subsequently maintained and replaced, there is no need to disassemble the outer roof module, which facilitates subsequent maintenance and saves manpower.

[0014] The utility model is further configured to include: a connecting plate, a clearance groove is opened on the top of the clamping plate, a connecting groove corresponding to the position of the clearance groove is opened on the top of the roof module, the connecting plate is placed in the clearance groove and the connecting groove, and is fixed with screws of the roof module.

[0015] The principle and effect of this technical solution: the setting of the connecting plate can connect the roof module and the clip-on plate, and the newly added groove wall will not increase the gap between the roof module and the clip-on plate relative to the keel frame, that is, it will not affect the original waterproof ability, and it is easier to disassemble and assemble the clip-on plate and the roof module, that is, it is more convenient for subsequent maintenance and replacement.

[0016] The utility model is further configured as follows: the bottom of the clamping groove is a curved surface.

[0017] The principle and effect of this technical solution: the setting of the arc surface makes it more difficult for rainwater entering the clamping groove to penetrate along the contact surface, thereby improving the waterproof ability.

[0018] The utility model is further configured as follows: a connecting rod is installed on the inner side of the keel frame, a sliding block is slidably sleeved on the connecting rod, an adjusting bolt is inserted on the top of the limit strip, the end of the adjusting bolt is threadedly inserted into the sliding block, and the end of the adjusting bolt extends to abut against the connecting rod.

[0019] The principle and effect of this technical solution: the setting of the connecting rod is similar to the reinforcing rib, which improves the overall strength of the keel frame, and through the setting of the slider, the position of the limit strip can be adjusted according to the size of the roof module, so that the device can adapt to roof modules of different sizes, and the setting of the adjusting bolt can limit the slider, and by separating the adjusting bolt, the limit strip can also be disassembled and assembled for easy transportation.

[0020] The utility model is further configured as follows: a limiting column is arranged on the limiting strip, an inserting hole is opened at the bottom edge of the middle part of the clamping plate, and the limiting column is inserted into the inserting hole.

[0021] The principle and effect of this technical solution: the setting of the limit column makes the position of the clamping plate more accurate when it is installed on the clamping strip, and can also prevent the clamping plate from sliding along both sides of the clamping groove, playing a stopping role and facilitating installation.

[0022] The utility model is further configured that: the clamping plate is a steel component.

[0023] The principle and effect of this technical solution: because the clamping plate is a steel component, the external strength of the roof structure will not be reduced due to the setting of the clamping plate, that is, the influence of the setting of the clamping plate on the strength of the roof structure is reduced.

[0024] The utility model is further configured as follows: the material of the keel frame is steel.

[0025] The principle and effect of this technical solution: The steel keel frame gives the roof structure stronger pressure-bearing capacity and stability. BRIEF DESCRIPTION OF THE DRAWINGS
