Description

Technical Field

[0001] The present invention relates to a double-groove joist fixture system. Background Art

[0002] The double-groove joist of the disc buckle type scaffolding support is a support device widely used in the field of civil construction. It is often used to support and fix building materials such as plates and pipes, which can effectively prevent the materials from breaking or deforming. In addition, it can also bear the weight of structures such as floors and roofs, effectively dispersing the pressure, thereby improving the stability and durability of the overall structure. Using joists can also reduce the risk of accidents during the formwork erection process.

[0003] The structural form of the double-groove joist device is mainly as follows: two channel steels are placed with their smooth surfaces facing each other and fastened by a bolt device and placed on the disc of the vertical pole of the disc buckle type scaffolding.

[0049] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0050] As Figures 1 to 10 shown, the present invention provides a double-groove joist fixture system, including:

[0051] Double-groove joist, including: two channel steels 1, the smooth surfaces of the two channel steels are arranged opposite to each other at intervals and connected; the smooth surfaces of the two channel steels are spaced apart by a preset distance;

[0052] Fixture, including: a double-groove joist fastening part and a vertical rod fastening part connected into one body;

[0053] A vertical rod arranged on the fixture, and a joist is supported on the vertical rod.

[0054] As Figure 1As shown in the figure, in an embodiment of the double-channel joist fixture system of the present invention, a sleeve 2 is provided between the smooth surfaces of the channel steels arranged at intervals. A connecting bolt 3 passes through the first channel steel 1, the sleeve 2 and the second channel steel 1 in sequence, so as to realize the arrangement and connection of the smooth surfaces of the two channel steels at intervals.

[0055] As Figures 2 to 7 shown in the figure, in an embodiment of the double-channel joist fixture system of the present invention, the vertical rod fastening part includes:

[0056] A socket pipe 4 is provided with a vertically penetrating socket hole 5 inside for inserting a vertical rod 6; an external thread 7 is provided on the outer side wall of the lower part of the socket pipe, and a fastening nut 8 is sleeved on the external thread, and an internal thread matching the external thread is provided on the inner side wall of the fastening nut 8.

[0057] In an embodiment of the double-channel joist fixture system of the present invention, the socket hole 5 is a cone with a larger upper part and a smaller lower part.

[0058] In an embodiment of the double-channel joist fixture system of the present invention, the taper of the cone is 1°.

[0059] In an embodiment of the double-channel joist fixture system of the present invention, a compression seam 9 perpendicular to the external thread and truncating the external thread is further provided on the outer side wall of the external thread at the lower part of the socket pipe 4.

[0060] Here, the working principle of the fixture body and the vertical rod: The vertical rod is inserted into the socket hole of the fixture body. After adjusting the lifting height of the vertical rod (the vertical rod protrudes from the top of the socket hole), the fastening nut at the bottom is rotated. Since the socket hole is a cone with a larger upper part and a smaller lower part (taper 1°). After rotating the fastening nut, the gap of the compression seam shrinks, resulting in the engagement of the socket hole and the vertical rod, realizing the locking of the vertical rod. The advantage of this design is that the required lifting height of the vertical rod can be quickly adjusted as needed. The original lifting device consisted of a tooth tube and a vertical rod. After the tooth tube was inserted into the double-channel joist, the vertical rod was inserted into the tooth tube, and the lifting height was adjusted by threads. The fixture body involved in the present invention can already achieve the adjustment of height, so the function of the original combination of the tooth tube and the vertical rod can be replaced by the vertical rod involved in the present invention.

[0061] As Figures 3 to 7 shown in the figure, in an embodiment of the double-channel joist fixture system of the present invention, the double-channel joist fastening part includes:

The two channel steels of the double-channel joist are respectively sleeved in a corresponding limiting space 12, and the smooth surface of each channel steel is attached to the outer side wall of the socket pipe;

[0064] The lower turning plate 11 is also provided with screw holes, and fastening bolts 14 are inserted into the screw holes. The tail of each fastening bolt 14 abuts against the back of the smooth surface of the channel steel 1.

[0065] Here, the principle of fastening the fixture to the double channel steel: The channel steel is sleeved in the two limiting spaces, and the positions of the two limiting spaces on the channel steel can be adjusted according to actual needs. Finally, the fastening bolts on both sides of the fixture body are rotated to realize the function of fixing the channel steel.

[0066] As Figures 8 to 10 shown, in an embodiment of the double channel beam fixture system of the present invention, a U-shaped frame 15 for supporting the beam 16 is provided at the top of the vertical rod 6, and a hydraulic baffle device for clamping the beam 16 is provided on the U-shaped frame 15.

[0074] 1. The fixture has a device for fastening to the double channel beam to avoid vibration;

[0075] 2. The fastening device has the characteristics of efficient and reliable fastening construction;

[0076] 3. It supports rapid adjustment of the height of the lifting vertical rod, improving construction efficiency;

[0077] 4. The fixture is easy to operate and can be reused.

[0078] The present invention can solve the problems that during the construction and use of a double-groove joist device, there are no fastening measures between its lifting device and the double-groove joist, the adjustment of the lifting height is cumbersome, and the joist shakes, so as to ensure the safety during the use of the double-groove joist device and the convenience of construction.
