Description

Technical Field

[0001] The present application relates to the technical field of combined wall standard sections, and in particular to a steel formwork concrete combined L-shaped column standard section. Background Art

[0002] Steel-membrane concrete structure is a combination of steel and concrete formed by pouring concrete inside with steel structural members as templates. Compared with traditional concrete buildings, steel-formed concrete composite structures can be factory-produced, integrated, standardized and digitally modeled. Steel-formed beam and column structures are more common structures in steel-formed concrete composite structures. As important supporting components of buildings, their performance directly affects the cost and safety performance of building characters.

[0003] In the related art, when constructing steel structure components, in order to improve the stability of the steel structure during welding, a standard section is usually installed between two special-shaped columns by welding. The standard section plays a transition role between the two special-shaped columns to reduce the force between the two special-shaped columns, thereby improving the stability of the steel structure.

[0004] With regard to the above-mentioned related technologies, the inventors believe that since the wall thickness between the standard section and the special-shaped column is relatively thin, deviations are very likely to occur if the standard section and the special-shaped column are directly butt-jointed, resulting in misalignment and gaps between the standard section and the special-shaped column during welding, leading to poor stability at the joint between the standard section and the special-shaped column. Summary of the invention

[0005] In order to improve the stability of the standard section and the special-shaped column after docking, the present application provides a steel formwork concrete combined L-shaped column standard section.

Since the wall thickness of the cover plates is greater than the wall thickness of the standard node, the contact area between the end of the special-shaped column and the end of the standard node is increased, so that when the end of the special-shaped column and the end of the standard node are connected, the end of the special-shaped column only needs to be fixed to the cover plate. The cover plates reduce the requirements for the accuracy of the connection between the special-shaped column and the standard node, reduce the misalignment phenomenon when the standard node and the end of the special-shaped column are connected, and achieve the effect of improving the stability of the standard node and the special-shaped column after the connection.

[0009] Optionally, an annular plate is provided inside the standard node body, a circumferential side wall of the annular plate is fixedly connected to a circumferential inner wall of the standard node body, and the annular plate is provided with a through hole penetrating the annular plate.

[0020] By adopting the above technical scheme, when the cover plate and the clamping assembly are clamped and fixed, the inner rod and the outer sleeve are fixed by the self-locking assembly, and then the self-locking assembly is unlocked by the unlocking assembly, so that the tension spring drives the inner rod to slide toward the end where the outer sleeve and the ring plate are fixed, until the cover plate abuts against the end of the standard node body. At this time, the tension spring is still in a stretched state and always provides a pulling force to the cover plate toward the middle of the standard node body, thereby improving the fitting effect of the cover plate and the end of the standard node body, providing convenience for the staff to fix the cover plate and the standard node body for the second time in the later stage, and improving the fixing quality.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The embodiment of the present application discloses a steel formwork concrete combined L-shaped column standard section.

[0038] Example 1

[0039] Reference Figure 1 and Figure 2 A steel formwork concrete combined L-shaped column standard section includes a standard section body 1, the cross section of the standard section body 1 is L-shaped, the interior of the standard section body 1 is a hollow structure, and the two ends of the standard section body 1 are mutually connected. In this application document, the length of the standard section body 1 is 80 cm.

[0040] The interior of the standard node 1 is fixed with a ring plate 3 by welding, the ring plate 3 is parallel to the end of the standard node 1, and the distance between the ring plate 3 and the ports at both ends of the standard node 1 is 40 cm. The two ends of the standard node 1 are fixed with a cover plate 2 by welding. The cover plate 2 is provided with two through holes 21, which penetrate the cover plate 2 and communicate with the interior of the standard node 1, and the side wall of the cover plate 2 is thicker than the side wall thickness of the standard node 1. The ring plate 3 is provided with two through holes 31, which penetrate the ring plate 3, and the through holes 21 and the through holes 31 are aligned one by one along the length direction of the standard node 1. The ring plate 3 is provided with a plurality of air holes 32, and the air holes 32 penetrate the ring plate 3. Before pouring concrete into the standard section body 1, the ring plate 3 is first fixed to the inside of the standard section body 1 by welding, and the ring plate 3 is used to strengthen the inside of the standard section body 1, thereby reducing the deformation of the standard section body 1 when pouring concrete into the standard section body 1 later. Then, the cover plate 2 is welded to both ends of the standard section body 1, and then the end of the special-shaped column and the cover plate 2 are welded and fixed. The cover plate 2 reduces the accuracy required for docking the special-shaped column and the standard section body 1, so that the cover plate 2 can eliminate the misalignment between the special-shaped column and the standard section body 1, thereby improving the stability of the connection between the special-shaped column and the standard section body 1. After the welding work of the special-shaped column and the standard section body 1 is completed, concrete is injected into the standard section body 1 through the through hole 21. The concrete passes through the ring plate 3 from the through hole 31 in turn, and then passes through the cover plate 2 at the other end of the standard section body 1 to flow into the special-shaped column. After filling the entire special-shaped column, the entire standard section body 1 is filled. When pouring concrete, the air in the standard section body 1 can be discharged through the air hole 32, so that the concrete can fill the entire standard section body 1.

[0041] The implementation principle of a steel formwork concrete combined L-shaped column standard section in Example 1 of the present application is as follows: first, the ring plate 3 is welded and fixed to the inside of the standard section body 1, and then the cover plate 2 is welded and fixed to the two ends of the standard section body 1, and then the special-shaped column and the cover plate 2 are welded, and concrete is injected from the through hole 21 until the interior of the entire special-shaped column and the interior of the standard section body 1 are filled. The ring plate 3 plays a good supporting role for the interior of the standard section body 1, reducing the deformation caused by the squeezing of the concrete on the interior of the standard section body 1, and the cover plate 2 reduces the accuracy required for the docking of the special-shaped column and the standard section body 1, thereby improving the stability of the connection between the special-shaped column and the standard section body 1.

[0042] Example 2

[0043] The difference between this embodiment 2 and embodiment 1 is that: Figure 3 and Figure 4 , multiple vertical rods 4 are welded and fixed along the length direction of the standard node body 1 on both sides of the ring plate 3, and the vertical rods 4 are arranged around the through hole 21 and the through hole 31. The vertical rods 4 are provided with a clamping assembly 5 at the end away from the ring plate 3, and the cover plate 2 is provided with a plurality of clamping grooves 22 that are mutually clamped and matched with the clamping assembly 5 on the side close to the ring plate 3. Before welding and fixing the cover plate 2 and the standard node body 1, the clamping assembly 5 is first inserted into the clamping groove 22 to preliminarily fix the cover plate 2 and the standard node body 1, and then the cover plate 2 and the standard node body 1 are welded and fixed, thereby reducing the deformation of the cover plate 2 due to heat when the cover plate 2 and the standard node body 1 are welded, or the position movement of the ends of the cover plate 2 and the standard node body 1 during the welding process, thereby improving the accuracy of welding the cover plate 2 and the standard node body 1.

[0044] Reference Figure 4 and Figure 5 The vertical rod 4 includes an inner rod 41, an outer sleeve 42 and a tension spring 43. The inner rod 41 is located in the outer sleeve 42, and the inner rod 41 is slidably connected to the outer sleeve 42 along the length direction of the outer sleeve 42. The end of the outer sleeve 42 away from the inner rod 41 is welded and fixed to the surface of the ring plate 3. The clamping assembly 5 is arranged at the end of the inner rod 41 away from the outer sleeve 42. The tension spring 43 is located in the outer sleeve 42. One end of the tension spring 43 is glued and fixed to the end of the inner rod 41 away from the clamping assembly 5, and the other end of the tension spring 43 is glued and fixed to the outer sleeve 42, and the tension spring 43 is always in a stretched state.

[0045] Reference Figure 6 and Figure 7 A self-locking component 6 for fixing the inner rod 41 and the outer sleeve 42 and an unlocking component 7 for unlocking the self-locking component 6 are provided between the inner rod 41 and the outer sleeve 42.

[0046] Insert the clamping assembly 5 into the clamping groove 22 of the cover plate 2. At this time, the self-locking assembly 6 is in a self-locking state, so that the inner rod 41 and the outer sleeve 42 are fixed, so that the cover plate 2 and the inner rod 41 are fixed, and then the self-locking assembly 6 is unlocked by the unlocking assembly 7, and the tension spring 43 drives the inner rod 41 to slide in the direction of the ring plate 3 until the cover plate 2 abuts against the end of the standard section body 1. At this time, the tension spring 43 is still in a tensioned state. Through the above structure, the cover plate 2 can fit tightly with the end of the standard section body 1, further reducing the gap between the cover plate 2 and the standard section body 1, thereby improving the welding effect when welding the cover plate 2 and the standard section body 1.

[0047] Reference Figure 5 The clamping assembly 5 includes a pair of clamping plates 51 and a pair of clamping springs 52. The two clamping plates 51 are respectively located on both sides of the end of the inner rod 41, and one side of the clamping plate 51 is hinged to the end of the inner rod 41. One end of the clamping spring 52 is glued and fixed to the clamping plate 51, and the other end of the clamping spring 52 is glued and fixed to the inner rod 41. When the cover plate 2 is buckled on the end of the inner rod 41, after the clamping plate 51 is extended into the clamping groove 22, the clamping spring 52 bounces the two clamping plates 51 to both sides, so that the clamping plate 51 is clamped in the clamping groove 22, thereby realizing the clamping and fixing between the end of the inner rod 41 and the cover plate 2.

[0048] Reference Figure 5 and Figure 7 A placement groove 411 is provided on the side wall of the inner rod 41 at one end away from the clamping assembly 5, and the self-locking assembly 6 is located in the placement groove 411. The self-locking assembly 6 includes a locking block 61 and a self-locking spring 62. One end of the self-locking spring 62 is glued and fixed to the inner rod 41, and the other end of the self-locking spring 62 is glued and fixed to the locking block 61. A locking hole 421 that is engaged with the locking block 61 is provided on the side wall of the outer sleeve 42 near one end of the inner rod 41.

[0049] When the staff connects the cover plate 2 with the snap-fit ​​assembly 5, the self-locking spring 62 pops the locking block 61 out of the placement groove 411 and snaps it into the locking hole 421, so that the inner rod 41 and the outer sleeve 42 are relatively fixed, and the snap-fit ​​assembly 5 has good stability, which makes it convenient for the staff to insert the snap-fit ​​assembly 5 into the snap-fit ​​groove 22.

[0050] Reference Figure 6 and Figure 8 The unlocking assembly 7 includes an insertion rod 71, a push rod 72 and a guide sleeve 73. One end of the insertion rod 71 is conical. A fixing rod 731 is welded and fixed between the guide sleeve 73 and the ring plate 3. The push rod 72 passes through the inside of the guide sleeve 73 and is slidably connected with the guide sleeve 73 in the direction toward the lock hole 421. The conical end of the insertion rod 71 passes through the through hole 21 and the through hole 31 in sequence along the length direction of the standard node body 1, and drives the push rod 72 to slide in the direction of the lock hole 421 when inserted into the inside of the standard node body 1.

[0051] After the clamping assembly 5 is clamped into the clamping groove 22, the conical end of the insertion rod 71 is inserted into the standard joint body 1 along the length direction of the standard joint body 1, so that the insertion rod 71 drives the push rod 72 to move toward the locking hole 421, and the locking block 61 is pushed out of the locking hole 421 and retracted into the placement groove 411 by the push rod 72, and then the tension spring 43 drives the inner rod 41 to move in the direction of the ring plate 3, and drives the cover plate 2 to move through the clamping assembly 5, so that the cover plate 2 and the end of the standard joint body 1 are abutted, and the tension spring 43 is still in a stretched state at this time, so that the cover plate 2 and the standard joint body 1 have a good fitting effect, so as to improve the welding and fixing effect when the cover plate 2 and the standard joint body 1 are welded.

[0052] The implementation principle of a steel formwork concrete combined L-shaped column standard section in Example 2 of the present application is as follows: before welding the cover plate 2 and the end of the standard section body 1, first buckle the cover plate 2 on the end of the inner rod 41, and snap the clamping assembly 5 into the clamping groove 22 to clamp and fix the cover plate 2 and the inner rod 41, then insert the insertion rod 71 into the standard section body 1, so that the insertion rod 71 drives the push rod 72 to slide in the direction of the lock hole 421, and the lock block 61 is pushed back into the placement groove 411 by the push rod 72, and the tension spring 43 drives the inner rod 41 to move toward the ring plate 3, and makes the cover plate 2 abut against the end of the standard section body 1, so as to improve the stability between the cover plate 2 and the standard section body 1 during welding, thereby improving the welding quality and effect of the cover plate 2 and the standard section body 1 after welding.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
