Description

Technical Field

[0001] The utility model relates to the technical field of connection devices, in particular to an assembled factory building connection device. Background Art

[0002] An assembled factory building is a building structure constructed using load-bearing steel materials such as I-beams, and then covered with an external steel structure (plate-like materials such as corrugated steel plates). When connecting the external steel structure and the steel structure body, screws need to be nailed to the steel structure body from the outside. Generally, the screws are directly penetrated through the corrugated steel plates and connected to the steel structure body through threads. However, this connection method can only be performed when the corrugated steel plates are close to the recessed position of the steel structure. Installing them on the steel structure at the protruding position of the corrugated steel plates will cause the corrugated steel plates to deform.

[0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an assembled factory building connection device.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an assembled factory building connection device, including a connecting piece arranged between a crossbeam I-beam and a corrugated steel plate, the connecting piece is a horizontally placed quadrangular prism, and a side of the connecting piece that contacts the surface of the crossbeam I-beam is provided with an inwardly recessed accommodating cavity, the other three side surfaces of the connecting piece are matched with the surface shape of the corrugated steel plate, and a side locking screw hole is provided on each of the three side surfaces of the connecting piece, and threads are provided in the side locking screw holes on the two side surfaces adjacent to the contact surface of the connecting piece with the crossbeam I-beam, and a screw hole coaxial with the upper locking screw hole on the side of the connecting piece away from the crossbeam I-beam is provided on the crossbeam I-beam, and a second locking bolt extending to the top of the connecting piece is threadedly connected to the screw hole.

[0006] By adopting the above technical solution, the second locking bolt is first used to fix the connecting piece on the crossbeam I-beam, and then the corrugated steel plate is placed on the connecting piece, and then the connecting piece is extended into the structure of the corrugated steel plate facing the recessed part of the crossbeam I-beam, and the first locking bolt is used to connect the corrugated steel plate and the connecting piece, thereby completing the connection between the corrugated steel plate, the connecting piece and the crossbeam I-beam, and utilizing the structure of the sealing groove side wall and the recessed part of the corrugated steel plate to further increase the stability of the installation of the corrugated steel plate, and prevent the corrugated steel plate from being deformed when the first locking bolt locks the corrugated steel plate at a position where the corrugated steel plate protrudes compared to the crossbeam I-beam.

[0007] The utility model is further configured as follows: the connecting piece is symmetrically arranged on the other two sides adjacent to the contact surface of the crossbeam I-beam.

[0008] By adopting the above technical solution and utilizing the structure in which the two sides of the connecting piece are symmetrically arranged, when the first locking bolt is connected to the threads in the upper locking screw holes on the two side surfaces of the connecting piece, the corrugated steel plate can be connected to the connecting piece in an inclined direction.

[0009] The utility model is further configured as follows: a first locking bolt is threadedly connected in each of the side locking screw holes on the left and right side surfaces of the connecting piece, and the nut of the first locking bolt is located above the corrugated steel plate.

[0010] By adopting the above technical solution, the locking position of the first locking bolt is set at an inclined position of the corrugated steel plate. On rainy days, rainwater falls on the surface of the corrugated steel plate. The first locking bolt is located in an inclined position, and the first locking bolt rises from the depression on the corrugated steel plate to prevent rainwater from accumulating in the depression on the corrugated steel plate, thereby preventing rainwater from penetrating through the holes of the corrugated steel plate along the first locking bolt and penetrating into the bottom of the corrugated steel plate.

[0011] The utility model is further configured as follows: sealing grooves coaxial with the side locking screw holes and the first locking bolts are opened on the left and right side surfaces of the connecting piece, an inner sealing ring is clamped in the sealing groove, and the upper surface of the inner sealing ring abuts against the lower surface of the corrugated steel plate.

[0012] By adopting the above technical solution, when the first locking bolt passes through the corrugated steel plate and is connected to the connecting piece, the inner sealing ring is used to wrap the area between the corrugated steel plate and the connecting piece, thereby sealing the water that penetrates through the hole through the first locking bolt, thereby reducing the probability of roof leakage.

[0013] The utility model is further configured as follows: an outer sealing ring is provided between the first locking bolt nut and the upper surface of the corrugated steel plate.

[0014] By adopting the above technical solution and utilizing the outer sealing ring, the waterproofness of the hole through which the first locking bolt passes through the corrugated steel plate is further increased, thereby enhancing the use effect.

[0015] The utility model is further configured as follows: the second locking bolt nut is located below the corrugated steel plate.

[0016] By adopting the above technical solution, the second locking bolt is hidden under the corrugated steel plate. At the same time, the second locking bolt fixes the connecting piece to the I-beam of the beam. The corrugated steel plate is used to block the second locking bolt. On the one hand, it prevents rainwater from directly contacting the second locking bolt, reducing the probability of rusting. On the other hand, the second locking bolt can also be produced using cheap materials that have not undergone rust-proofing treatment, thereby reducing production costs.

[0017] The present invention is further configured such that: the second locking bolt nut can also be located above the corrugated steel plate.

[0018] By adopting the above technical solution, when the second locking bolt nut is located above the corrugated steel plate, the second locking bolt can also lock the corrugated steel plate to the connecting piece, further enhancing the connection effect of the corrugated steel plate, the connecting piece and the crossbeam I-beam.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The structure of the connecting piece protruding and extending into the recessed part of the corrugated steel plate, and the first locking bolt locking the corrugated steel plate and the connecting piece from the side of the recessed part of the corrugated steel plate, can not only prevent the first locking bolt from locking the corrugated steel plate, the connecting piece and the crossbeam I-beam at the protruding position of the corrugated steel plate, thereby increasing the use effect, but also the first locking bolt arranged on the side of the recessed part of the corrugated steel plate can effectively prevent rainwater from accumulating at the hole opening of the corrugated steel plate where the first locking bolt passes through the corrugated steel plate, thereby reducing the water seepage rate.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0030] This is an assembled factory building connection device, such as Figures 1 to 7 As shown, it includes a connector 11 arranged between the crossbeam I-beam 16 and the corrugated steel plate 17. The connector 11 is a horizontally placed quadrangular prism, and a side of the connector 11 that contacts the surface of the crossbeam I-beam 16 is provided with an inwardly recessed accommodating cavity 15. The other three side surfaces of the connector 11 match the surface shape of the corrugated steel plate 17. A side locking screw hole 13 is provided on each of the three side surfaces of the connector 11. Threads are provided in the side locking screw holes 13 on the two side surfaces adjacent to the contact surface of the connector 11 and the crossbeam I-beam 16. A screw hole coaxial with the side locking screw hole 13 on the side of the connector 11 away from the crossbeam I-beam 16 is provided on the crossbeam I-beam 16. The screw hole is threadedly connected to a second screw hole extending to the top of the connector 11. Two locking bolts 18 are symmetrically arranged on the other two sides adjacent to the contact surface of the connecting piece 11 and the crossbeam I-beam 16. A first locking bolt 19 is threadedly connected to each of the side locking screw holes 13 on the left and right side surfaces of the connecting piece 11. The nut of the first locking bolt 19 is located above the corrugated steel plate 17. A sealing groove 12 coaxial with the side locking screw hole 13 and the first locking bolt 19 is provided on the left and right side surfaces of the connecting piece 11. An inner sealing ring 20 is clamped in the sealing groove 12. The upper surface of the inner sealing ring 20 abuts against the lower surface of the corrugated steel plate 17. An outer sealing ring 21 is provided between the nut of the first locking bolt 19 and the upper surface of the corrugated steel plate 17. The nut of the second locking bolt 18 is located below the corrugated steel plate 17.

[0031] The second locking bolt 18 is used to install the connector 11 on the beam I-beam 16, and then the top surface and the inclined side of the connector 11 are used to extend it into the recess of the corrugated steel plate 17 and cooperate with it, and then the first locking bolt 19 is used to penetrate the corrugated steel plate 17 from the recessed side wall of the corrugated steel plate 17 and be threadedly connected to the side wall of the connector 11, that is, the first locking bolt 19 connects the corrugated steel plate 17 to the connector 11 in an inclined direction. When the corrugated steel plate 17 is installed on the roof, if the bottom wall of the recess of the corrugated steel plate 17 and the beam I-beam 16 are located on the same vertical line, the first locking bolt 19 can be directly penetrated through the bottom wall of the recess of the corrugated steel plate 17 and perpendicular to the beam I-beam 16, complete the installation of the corrugated steel plate 17 and the beam I-beam 16. When the top position of the depression of the corrugated steel plate 17 is in the same vertical line as the beam I-beam 16, first place the connector 11 on the beam I-beam 16, and lock the connector 11 and the beam I-beam 16 with the second locking bolt 18. The specific connection method is that the second locking bolt 18 passes through the through hole 14 and is threadedly connected and locked with the beam I-beam 16. The side wall of the connector 11 is kept parallel to the depressed side wall of the corrugated steel plate 17, and the inner sealing ring 20 is inserted into the sealing groove 12. At this time, the inner sealing ring 20 surrounds the outside of the side locking screw hole 13, and then the corrugated steel plate 17 is placed on the connector 11 , and make the connecting piece 11 stuck into the depression on the surface of the corrugated steel plate 17, then put the outer sealing ring 21 on the first locking bolt 19, and then pass the first locking bolt 19 through the side wall of the depression of the corrugated steel plate 17, and make the first locking bolt 19 pass through the inner sealing ring 20 and be threadedly connected with the side locking screw hole 13 and locked; use the inner sealing ring 20 to form a closed space between the corrugated steel plate 17 and the connecting piece 11, thereby preventing rainwater from passing through the corrugated steel plate 17 and dripping down into the factory building. At the same time, the outer sealing ring 21 and the nut of the first locking bolt 19 can also form a space on the surface of the corrugated steel plate 17 to close the corrugated steel plate 17 and the through hole 14, thereby preventing rainwater from passing through the corrugated steel plate 17, further The waterproof effect is increased. At the same time, the structure of connecting the corrugated steel plate 17 to the connecting piece 11 with the first locking bolt 19 at an angle can also prevent deformation of the corrugated steel plate 17 when the first locking bolt 19 is directly rotated at the concave and convex position of the corrugated steel plate 17 to complete the connection between the corrugated steel plate 17 and the crossbeam I-beam 16, thereby preventing the corrugated steel plate 17 from being deformed and causing its mechanical properties to decline, thereby increasing the use effect of the corrugated steel plate 17. The second locking bolt 18 is arranged in the structure below the corrugated steel plate 17, and the corrugated steel plate 17 can also be used to isolate the second locking bolt 18 from rainwater, thereby being able to use the second locking bolt 18 of low corrosion resistance material, thereby reducing costs. Example 2

[0032] The difference from Example 1 is that the nut of the second locking bolt 18 can also be located above the corrugated steel plate 17; the nut of the second locking bolt 18 is set above the corrugated steel plate 17, and the second locking bolt 18 is used to further increase the connection effect between the corrugated steel plate 17 and the connecting piece 11.
