Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a horizontal rod adapter device of a disc-type rack formwork support system and a horizontal connection structure between vertical rods of a non-modular arrangement. Background Art

[0002] The buckle type frame formwork support system is generally arranged according to the 300mm module when erected, that is, the arrangement interval of two adjacent vertical poles is a multiple of 300mm. The interval of the vertical pole arrangement is generally 300mm, 600mm, and 900mm. The length of the corresponding horizontal rod is also a 300mm module, that is, the length of the horizontal rod is 300mm, 600mm, and 900mm. Since the beam width is not necessarily designed according to the multiple of the above module, the bottom vertical pole of the beam will appear during the erection process. If the pole is not centered, the side poles of the beam will be too close to the edge of the beam and there will be no operating space, or the side poles of the beam will be too far from the edge of the beam and the cantilever will be too large. When the inner and outer frames of the rack are erected, the poles in the inner frame plate and the middle of the outer frame will also encounter the problem of non-modular arrangement of the poles. When the poles are not arranged in a modular way, they are usually connected by steel pipes. However, the inner and outer frames are separated as a whole, and the adjustment span becomes a weak point. In addition, the steel pipe connection uses pipe fasteners and disc-type connections, which are two connection structures, which will also lead to the deterioration of the structural stress of the steel pipe connection node. Among them, steel pipe fastening refers to the connection of steel pipes without joints at both ends to the pole body through pipe fasteners. Utility Model Content

[0005] Furthermore, the horizontal rod adapter of the disc-type rack formwork support system provided by the utility model has the slot hole as a sunken groove, and the nut above abuts against the upper surface inside the sunken groove instead of abutting against the upper surface of the trough box.

[0007] Furthermore, the utility model provides a horizontal rod adapter device of the disc-type rack formwork support system, and the trough box is a cube or a cylinder.

[0023] The present invention is described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are all simplified and not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0024] Please refer to Figures 1 to 3 The embodiment of the present invention provides a horizontal rod adapter 100 of a disc-type frame formwork support system, including a linear trough box 110, wherein the trough box 110 can be a cube or a cylinder, and a screw 120 is provided for sliding along the length direction of the trough box 110, and a slot 112 is vertically penetrated along the length direction of the trough box 110, and the screw 120 is vertically inserted and slidably set in the slot 112, and the screw 120 is threadedly connected with an active disc 140 and two nuts 130 from top to bottom. The active disc 140 has the same structure as the disc 41 on the vertical pole 4 of the disc-type frame formwork support system, and the upper nut 130 abuts against the upper surface of the trough box 110, and the lower nut 130 abuts against the lower surface of the trough box 110, and a through hole 111 matching the diameter of the vertical pole 4 of the disc-type frame formwork support system is vertically penetrated at the opposite end of the slot 112 on the trough box 110. The width of the slot 112 matches the outer diameter of the screw 120 , and the structure of the active disc 140 is the same as the disc 41 on the vertical pole 4 of the disc-type rack formwork support system, which means that the active disc 140 is the disc 41 on the vertical pole 4 .

[0025] Please refer to Figures 1 to 2 In order to improve the stability of the screw rod 120 sliding on the trough box 110, the embodiment of the present invention provides a horizontal rod adapter device 100 of the disc-type rack formwork support system, wherein the slot hole 112 is a sunken groove, and the nut 130 above is against the upper surface in the sunken groove instead of against the upper surface of the trough box. The sunken groove is a stepped groove, which means that the cross section of the slot hole 112 is a stepped shape. At this time, the nut 130 above is restricted to sliding in the sunken groove, thereby improving the stability of the screw rod 120 driving the active disc 140 before and after sliding on the trough box 110. In order to maintain the verticality of the screw rod 120, the slot hole 112 is not limited to the above-mentioned strip groove structure, but can be a plurality of bolt holes distributed along a straight line that match the outer diameter of the screw rod 120. The screw rod 120 is inserted into a bolt hole at a different position to drive the active disc 140 to adjust its position along the length direction of the trough box 110.

[0026] Please refer to Figure 1 In order to facilitate the threaded connection of the active disc 140 on the screw rod 120, the horizontal rod adapter 100 of the disc-type rack formwork support system provided by the embodiment of the utility model has the screw rod 120 in a straight line shape. Of course, the screw rod can also be T-shaped. In this case, the active disc 140 is threadedly connected from the lower end of the screw rod 120.

The horizontal rod adapter 100's active disc 140 slides within the slot 112 via the screw 120 to adjust the distance between it (the active disc 140) and the disc 41 of the other vertical rod 4. The horizontal rod adapter 100 adjusts the active disc 140 and the disc 41 of the other vertical rod 4 to the same horizontal height by rotating the active disc 140 relative to the screw 120, so that the two ends of the horizontal rod 5 are connected to the active disc 140 of the horizontal rod adapter 100 and the disc 41 of the other vertical rod 4 respectively through the snap joints 51 thereon. When the nut 130 is tightened, the screw 120 and the active disc 140 thereon are locked in the adjusted position. The sidewalls of the through hole 111 can be provided with multiple holes for the pins 200 to pass through.

The two ends of the horizontal rod respectively maintain a disc-type connection structure with the disk 41 of one vertical rod 4 and the flexible disk 140 of the horizontal rod adapter device 100 on another vertical rod 4. This makes the connection node of the horizontal rod have the advantages of good structural stress and strong load bearing capacity, and avoids the problem of different connection structures resulting in poor structural stress at the node when the non-modularly arranged vertical rods 4 are connected by steel pipes. That is, the present invention can horizontally connect the non-modularly arranged vertical rods of the disc-type frame formwork support system through the horizontal rod 5 and its adapter device 100, and maintain the connection nodes at both ends of the horizontal rod 5 as a disc-type connection structure, without mixing with steel pipe fasteners, and has the advantage of good structural stress.
