Abstract
Description
Technical Field
[0001] This utility model relates to the field of raft foundation reinforcement support technology, specifically a raft foundation reinforcement support frame. Background Technology
[0002] A raft foundation reinforcement support frame is a structure used to support and secure the reinforcing steel bars in a raft foundation. Raft foundations are a common type of foundation in construction engineering. When the raft foundation is thick, the reinforcing steel bars have large diameters and multiple layers. Without a support frame, the upper layers of reinforcing steel bars cannot be fixed in the correct position, necessitating the construction of a reinforcement support frame to ensure stability and quality during construction.
[0003] In order to facilitate the adjustment of the height of the upper support, the existing raft foundation reinforcement support frame uses bolt collars to fix the upper support plate to the support column. However, the bolt collars provide support through friction. When the bolts are loose or the pressure is too high, the bolt collars are prone to slipping, which will cause the support frame to fail to support the upper raft foundation reinforcement. Utility Model Content
[0004] The purpose of this utility model is to provide a raft foundation steel reinforcement support frame to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a raft foundation reinforcement support frame, comprising a support column, wherein a support component is provided at the upper end of the support column and a folding component is provided at the lower end of the support column;
[0006] The support assembly includes a strip-shaped opening on the surface of the support column. An insert block is engaged inside the strip-shaped opening. A sleeve is movably fitted onto the upper surface of the support column. A support ring is fixedly fitted onto the upper end of the outer wall of the sleeve. Two insertion holes are symmetrically opened on the outer wall of the sleeve, and the same insert plate is inserted into the two insertion holes.
[0007] Preferably, the folding assembly includes a hinge, the upper end of which is hinged to the lower end of the support column, the lower end of which is hinged to a folding column, a fixing ring fixedly sleeved on the upper outer wall of the folding column, a fixing cylinder slidably sleeved on the surface of the hinge, and a locking base snapped into the lower end of the folding column.
[0008] Preferably, the lower end of the strip-shaped opening is provided with a right-angled groove, and the inner wall of the lower end of the strip-shaped opening matches the lower end surface of the insert block.
[0009] Preferably, both of the sockets are connected to the inner wall of the sleeve, and the sockets are matched with the insert plate.
[0010] Preferably, the length of the fixed cylinder is longer than the length of the hinge.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by selecting a suitable length of insert block and inserting it into the strip-shaped opening, then movably fitting the sleeve onto the surface of the support column, and then inserting the insert plate into the opening so that the lower end of the insert plate fits against the upper surface of the insert block, the insert block supports the insert plate, the insert plate supports the sleeve, the sleeve supports the support ring, and the support ring supports the upper raft slab reinforcement. This support structure can prevent the sleeve from loosening and sliding down, and the length of the insert block can be adjusted according to needs to support raft slab reinforcement of different heights.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5 This utility model provides a technical solution: a raft foundation steel reinforcement support frame, including a support column 1, a support component 2 provided at the upper end of the support column 1, and a folding component 3 provided at the lower end of the support column 1;
[0020] The support component 2 includes a strip-shaped opening 21, which is opened on the surface of the support column 1. An insert block 22 is snapped into the inside of the strip-shaped opening 21. A sleeve 23 is movably sleeved on the upper surface of the support column 1. A support ring 24 is fixedly sleeved on the upper end of the outer wall of the sleeve 23. Two insertion holes 25 are symmetrically opened on the outer wall of the sleeve 23. The same insert plate 26 is inserted into the two insertion holes 25. The insert plate 26 is supported by the insert block 22, the sleeve 23 is supported by the insert plate 26, the support ring 24 is supported by the sleeve 23, and the upper raft slab reinforcement is supported by the support ring 24. This support structure can prevent the sleeve 23 from loosening and sliding down, and the length of the insert block 22 can be adjusted as needed to support the raft slab reinforcement at different heights.
[0021] Preferably, the folding assembly 3 includes a hinge 31, the upper end of which is hinged to the lower end of the support column 1, and the lower end of the hinge 31 is hinged to a folding column 32. A fixing ring 33 is fixedly sleeved on the upper outer wall of the folding column 32. A fixing cylinder 34 is slidably sleeved on the surface of the hinge 31. A locking base 35 is snapped into the lower end of the folding column 32. The locking base 35 is placed at the position where support is needed, and then the folding column 32 is inserted into the locking base 35. Then, the hinge 31 and the support column 1 are rotated to keep the folding column 32 in a straight line. Then, the fixing cylinder 34 is pushed to lock into the upper end of the fixing ring 33. The fixing cylinder 34 fixes the support column 1 and the folding column 32 to both ends of the hinge 31, so that the entire column remains vertical.
[0022] Preferably, the lower end of the slot 21 is provided with a right-angled groove, and the inner wall of the lower end of the slot 21 matches the lower end surface of the insert 22. The right-angled groove prevents the insert 22 from sliding in the slot 21, so that the support of the insert 22 remains stable.
[0023] Preferably, both insertion ports 25 are connected to the inner wall of the sleeve 23, and the insertion ports 25 are matched with the insertion plate 26 so that the insertion plate 26 can be inserted into the sleeve 23 and contact the upper surface of the insertion block 22, so that the insertion block 22 supports the insertion plate 26.
[0024] Preferably, the length of the fixing cylinder 34 is longer than the length of the hinge 31, so that the fixing cylinder 34 can fix the support column 1 and the folding bracket 32 at both ends of the hinge 31 in a vertical straight line.
[0025] Specifically, when using this utility model, first place the snap-fit base 35 at the position requiring support, then insert the folding column 32 into the snap-fit base 35, then rotate the hinge 31 and support column 1 to keep them in a straight line with the folding column 32, then push the fixing cylinder 34 to lock onto the upper end of the fixing ring 33, and fix the support column 1 and folding column 32 to both ends of the hinge 31 through the fixing cylinder 34, so that the entire column remains vertical. Then, select an insert block 22 of appropriate length and insert it into the strip opening 21, then movably fit the sleeve 23 onto the surface of the support column 1, then insert the insert plate 26 into the insertion opening 25, so that the lower end of the insert plate 26 fits against the upper surface of the insert block 22. The insert block 22 supports the insert plate 26, the insert plate 26 supports the sleeve 23, the sleeve 23 supports the support ring 24, and the support ring 24 supports the upper raft slab reinforcement. This support structure can prevent the sleeve 23 from loosening and sliding down, and the length of the insert block 22 can be adjusted according to needs to support raft slab reinforcement of different heights.
