Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a connection node between a beam and a roof panel. Background Art

[0002] At present, in order to meet the needs of production and manufacturing, there are a large number of temporary buildings. Temporary building structures are usually assembled from container structures or overlapped with color steel plates. They have poor sound insulation, weak structural bearing capacity and are prone to rust. Compared with concrete buildings, the living experience is poor.

[0003] For brick structures, tile roofs can be used, but tile roofs are only suitable for small buildings and not for larger buildings. Temporary steel structure buildings use color steel plates to form roofs, which have low strength to resist wind loads and snow loads, are prone to leaks or being hit by hail, and have a low safety factor.

[0004] Conventional concrete roofs usually adopt the construction method of integral concrete pouring, which requires the support of formwork under the roof, tying steel bars and then pouring the whole. Therefore, cast-in-place concrete roofs are generally designed as flat roofs, but the drainage effect is poor; concrete sloping roofs are difficult to construct due to the difficulty of formwork support, which makes construction inconvenient and prone to quality problems. In addition, concrete roofs are cast-in-place at one time and cannot be disassembled or replaced. Utility Model Content

[0005] In order to improve the problem that concrete sloping roofs are difficult to disassemble and reuse, the present application provides a connection node between a beam and a roof panel.

[0006] The present application provides a connection node between a beam and a roof panel, which adopts the following technical solution:

[0007] A connection node between a beam and a roof panel, comprising an inclined top beam, a plurality of roof panels are installed between two adjacent inclined top beams, and two adjacent roof panels are overlapped with each other;

[0008] A limit bolt is arranged on the inclined top beam, and a bolt hole is opened on each of the roof panels. When the roof panels are installed on the inclined top beam, the limit bolt is inserted into the bolt hole.

[0009] Furthermore, the roof panel includes a main board surface and an eave, the thickness of the eave is smaller than that of the main board surface, the eave is coplanar with the upper surface of the main board surface, and the eave overlaps above the side of the adjacent roof panel where the eave is not provided.

[0010] Furthermore, the end surface of the main panel surface close to the overhanging eaves is pressed against the end surface of the adjacent roof panel surface at the end where the overhanging eaves is not provided.

[0011] Furthermore, the inclination angle of the upper surface of the roof panel is gentler than the inclination angle of the lower surface, and the thickness of the roof panel gradually increases towards the eaves.

[0012] Furthermore, the limiting bolt includes a nail column and a nail head, the nail column is partially fixed in the inclined top beam, and the nail head is located on a side of the nail column away from the inclined top beam;

[0013] The cross section of the nail head gradually decreases in a direction away from the nail column.

[0014] Furthermore, the bolt hole includes an inserting hole and a limiting hole, and the inserting hole is connected to the limiting hole;

[0015] The horizontal cross section of the plug hole matches the shape and area of ​​the maximum horizontal cross section of the nail head, and the vertical cross section of the limiting hole matches the vertical cross section of the nail head.

[0016] Furthermore, a lap platform is formed on the top surface of each of the inclined top beams, the lap platform is arranged along the length direction of the inclined top beam, and the side wall of the roof panel abuts against the side wall of the lap platform.

[0017] Furthermore, a ridge beam and a side beam are respectively provided at both ends of the inclined roof beam, and a plurality of limit bolts are fixed on the ridge beam and the side beams. Bolt holes for inserting the limit bolts on the ridge beam and the side beams are provided on the roof panel overlapped with the ridge beam and the side beams.

[0018] In summary, the present application includes at least one of the following beneficial effects:

[0019] 1. The present application sets limit bolts on the inclined roof beams and reserves bolt holes on the bottom wall of the roof panel, so that when installing the roof panel, the installation can be completed by simply overlapping the roof panel between two adjacent inclined roof beams, and the limiting bolts can be used to achieve the limiting position; when disassembling the roof panel, it is only necessary to gradually lift the roof panel from the top downward, and the installation and disassembly are convenient and quick; two adjacent roof panels are overlapped and installed, so that the roof panel can achieve structural self-waterproofing and self-drainage through its own structure.

[0020] 2. The roof panel includes an overhanging eave, so that the overhanging eave can overlap the top of the adjacent roof panel, so that the water on the roof panel can flow smoothly to the next roof panel, so as to achieve smoother drainage and reduce roof leakage.

[0021] 3. A lap platform is set on the inclined top beam to facilitate the two roof panels overlapped on the inclined top beam to be better pressed against the inclined top beam, making it more beautiful after installation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The embodiment of the present application discloses a connection node between a beam and a roof panel, referring to Figures 1 to 4 A connection node between a beam and a roof panel includes a plurality of parallel and spaced inclined top beams 1, one end of the inclined top beam 1 is connected to a ridge beam 4, and the other end is connected to a side beam 5, and a plurality of roof panels 2 are laid between two adjacent inclined top beams 1 to achieve shielding of the top of the building. It should be particularly noted that the roof panel 2 of the present application is a prefabricated concrete roof panel 2, which has a structural bearing capacity equivalent to that of a cast-in-place concrete roof.

[0029] A plurality of roof panels 2 are overlapped and installed in sequence between two adjacent inclined roof beams 1. Specifically, the roof panel 2 includes a main board surface 22 and an overhang 23. The thickness of the overhang 23 is less than that of the main board surface 22, and the overhang 23 is coplanar with the upper surface of the main board surface 22. When installing the roof panel 2, the overhang 23 of the upper roof panel 2 is overlapped with the top of the side of the adjacent lower roof panel 2 where the overhang 23 is not provided, and the end face of the main board surface 22 of the lower roof panel 2 is pressed against the end face of the main board surface 22 of the upper roof panel 2.

[0030] Furthermore, the inclination angle of the upper surface of the roof panel 2 is gentler than that of the lower surface, and the thickness of the roof panel 2 gradually becomes thicker towards the eaves 23, so that under the premise of meeting the overlapping installation requirements of the roof panels 2, the panel surfaces of multiple roof panels 2 facing the indoor side are coplanar, and the flatness and aesthetics of the indoor side are better.

[0031] When installing the roof panels 2, the roof panels 2 are laid one by one from the side beams 5 to the ridge beams 4. A bolt hole 21 is provided on the bottom wall of one side of each roof panel 2 overlapped to the inclined top beam 1, and a plurality of limit bolts 3 are arranged at intervals on each inclined top beam 1. When the roof panel 2 is overlapped on two adjacent inclined top beams 1, the limit bolts 3 are correspondingly inserted into the bolt holes 21.

[0032] The limiting bolt 3 includes a nail column 31 and a nail head 32 . The nail column 31 is partially anchored in the inclined top beam 1 . The nail head 32 is located on a side of the nail column 31 away from the inclined top beam 1 . The cross section of the nail head 32 gradually decreases in the direction away from the nail column 31 .

[0033] The bolt hole 21 includes a connected plug hole 211 and a limit hole 212. The horizontal cross section of the plug hole 211 matches the shape and area of ​​the maximum horizontal cross section of the nail head 32, and the vertical cross section of the limit hole 212 matches the vertical cross section of the nail head 32. When the roof panel 2 is hoisted onto the inclined top beam 1, the limit bolt 3 on the inclined top beam 1 is first aligned with the plug hole 211, and the limit bolt 3 is plugged into the plug hole 211, and then the roof panel 2 is pushed to slide, so that the limit bolt 3 slides along the limit hole 212 until the limit bolt 3 is clamped in the limit hole 212, and the side wall of the limit bolt 3 is tightly pressed against the bottom wall of the limit hole 212, the installation of the roof panel 2 is completed.

[0034] In this way, since the cross-section of the nail head 32 gradually decreases, the side wall of the nail head 32 forms a slope. When installing the roof panel 2, since the top wall area of ​​the nail head 32 is smaller, it is easier to align it into the plug-in hole 211, and the slope of the side wall guides the falling of the roof panel 2, so that the limit bolt 3 can be more smoothly plugged into the plug-in hole 211 on the roof panel 2.

[0035] In addition, the cross-section of the insertion hole 211 matches the shape and area of ​​the maximum cross-section of the nail head 32, so that after the limiting bolt 3 is inserted into the bolt hole 21, the side wall of the nail head 32 abuts against the side wall of the bolt hole 21, so that when the roof panel 2 is pushed to slide, the limiting bolt 3 can be pushed into the limiting hole 212 more smoothly; the limiting hole 212 is provided so that the roof panel 2 and the inclined top beam 1 can be clamped to form a force connection, thereby improving the connection strength between the roof panel 2 and the inclined top beam 1 and the installation stability of the roof panel 2.

[0036] Among them, a number of limit bolts 3 are fixed on the ridge beam 4 and the side beam 5, and bolt holes 21 for inserting the limit bolts 3 on the ridge beam 4 and the side beam 5 are provided on the roof panel 2 overlapped with the ridge beam 4 and the side beam 5. When the roof construction is carried out using the connection node of the roof panel 2 and the inclined top beam 1 of the present application, the roof panel 2 is first laid from the side beam 5, and the roof panel 2 is gradually overlapped and installed in the direction of the ridge beam 4 until the roof panel 2 between two adjacent inclined top beams 1 is laid. It should be noted that the roof panel 2 laid above the side beam 5 can be extended outward, so as to better realize the drainage of the roof. Since there is a limit bolt 3 between the side beam 5 and the roof panel 2, and there is also a limit bolt 3 on the roof panel 2 and the inclined top beam 1, even if the roof panel 2 is extended outward, it can still be stably installed.

[0037] In another embodiment, the top wall of the inclined roof beam 1 is further formed with a lap platform 11, which is arranged along the length direction of the inclined roof beam 1. When the roof panel 2 is overlapped on two adjacent inclined roof beams 1, the side wall of the roof panel 2 is tightly pressed against the side wall of the lap platform 11. The design of the lap platform 11 makes the roof more beautiful on the one hand, and can realize the waterproof structure construction between the roof panel 2 and the lap platform 11 on the other hand. The specific construction method of the waterproof structure is not described in detail in this application.

[0038] The implementation principle of a connection node between a beam and a roof panel in an embodiment of the present application is as follows: the core concept of the connection node design of the present application is to combine the traditional mortise and tenon structure assembly concept into concrete buildings, so that when forming a concrete roof, a stable connection node can be formed at the connection between the roof panel 2 and the top beam structure of the building without grouting; at the same time, each concrete component can be prefabricated and processed in the factory and transported to the site for assembly and construction. The components can be dismantled, replaced and reused, forming a concrete temporary building construction system, which has the convenience of quick installation and disassembly of steel structure temporary buildings, and also has the living comfort of concrete buildings.

[0039] In addition, when the connection node of the present application is constructed, there is no wet operation on site, which is clean and environmentally friendly, and reduces pollution to the environment. When installing the roof panel 2, it is only necessary to hoist the roof panel 2 piece by piece in the specified direction to achieve the installation of the roof, and the construction difficulty is low and the steps are simple.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
