Description

Technical Field

[0001] The invention belongs to the technical field of concrete-filled steel tube for nursing, and particularly relates to an earthquake-resistant pressure-dividing device for concrete-filled steel tube columns used in house design. Background Technique

[0002] Concrete-filled steel tube is to pour concrete into a steel tube and tamp it to increase the strength and stiffness of the steel tube. Generally, the concrete-filled steel tube with a concrete strength grade below C50 is called ordinary concrete-filled steel tube; the concrete-filled steel tube with a concrete strength grade above C50 is called high-strength concrete-filled steel tube; the concrete-filled steel tube with a concrete strength grade above C100 is called ultra-high-strength concrete-filled steel tube.

[0003] House design is a very important step in house construction. Concrete-filled steel tube columns are one of the structures often used in house design. A concrete-filled steel tube column is a structural member in which concrete is filled in the inner cavity of the steel tube, and the steel tube and the core concrete jointly bear the external load. Concrete has high compressive capacity but weak bending capacity. Steel has strong bending capacity and good elastoplasticity, but it is easy to lose axial compressive capacity when compressed. Concrete-filled steel tube can combine the advantages of both, making the concrete in a state of lateral compression, greatly improving the compressive capacity. At the same time, due to the existence of concrete, the stiffness of the steel tube is improved, and the two work together, thus greatly improving the bearing capacity.

[0004] Currently, when carrying out earthquake-resistant pressure division on a concrete-filled steel tube column, it is necessary to first fix the concrete-filled steel tube column on the base, and then disperse the pressure by attaching struts or supports around it to achieve the effect of earthquake-resistant pressure division.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0036] As Figure 1 shown, in an embodiment of the present invention, an earthquake-resistant pressure-dividing device for a concrete-filled steel tubular column based on house design includes: a base 1 and a connection groove 2 for connecting the concrete-filled steel tubular column. The earthquake-resistant pressure-dividing device for a concrete-filled steel tubular column based on house design further includes:

[0037] A locking assembly 3, disposed outside the concrete-filled steel tubular column, and the locking assembly 3 is used to clamp and fix the concrete-filled steel tubular column;

[0038] A positioning assembly 4, connected to the locking assembly 3, and the positioning assembly 4 is used to cooperate with the locking assembly 3 to position the concrete-filled steel tubular column.

[0039] When the earthquake-resistant pressure-dividing device for a concrete-filled steel tubular column based on house design is in use, first place the concrete-filled steel tubular column in the connection groove 2 to achieve preliminary positioning of the concrete-filled steel tubular column. Subsequently, place the locking assembly 3 on the concrete-filled steel tubular column and connect and fix it to the concrete-filled steel tubular column. Then, use the positioning assembly 4 to connect the locking assembly 3 to the ground and tighten and lock it to achieve fixation of the entire concrete-filled steel tubular column. The fixation effect is good, and the entire fixation process does not require unnecessary manual operations and does not require the use of a large number of screws, which saves both manpower and material resources and also saves a large amount of spare part costs. It is time-saving and labor-saving, convenient to use, and has a high degree of automation.

[0040] As Figures 1 to 5 shown, in an embodiment of the present invention, the locking assembly 3 includes:

[0041] The positioning sleeve 31 is provided with a plurality of positioning grooves 32 on the inner wall thereof, and a cylinder 33 is arranged inside each of the plurality of positioning grooves 32;

[0042] The air rod 34 is arranged inside the cylinder 33, and a fastening plate 35 is installed at one end of the air rod 34, and the fastening plate 35 cooperates with the side wall of the concrete-filled steel tube column.

[0043] In the embodiment of the present invention, the plurality of cylinders 33 are synchronously driven and connected through electrical signals.

[0044] When the locking assembly 3 is used, first, the positioning sleeve 31 is sleeved outside the concrete-filled steel tube column, and then the cylinder 33 is driven to operate. Since all the cylinders 33 are synchronously connected through electrical signals, when one of the cylinders 33 operates, the remaining cylinders 33 will also work synchronously. Then the cylinder 33 will push the air rod 34 outwards until the fastening plate 35 contacts the side wall of the concrete-filled steel tube column. Through the clamping action of all the fastening plates 35, the clamping of the concrete-filled steel tube column can be realized.

[0045] As Figures 1 to 5 shown, in the embodiment of the present invention, the positioning assembly 4 includes:

[0046] The fixing plate 41 is internally provided with a main motor 42 rotatably, and the output end of the main motor 42 is connected with a positioning screw 43, and the positioning screw 43 is used to cooperate with the ground to connect the fixing plate 41 to the ground;

[0047] The connecting assembly is rotatably arranged on the fixing plate 41, the connecting assembly is connected with the positioning sleeve 31, and the connecting assembly is used to connect and fix the concrete-filled steel tube column through the locking assembly 3;

[0048] The adaptation assembly is arranged on the side wall of the positioning sleeve 31.

[0049] As Figures 1 to 5 shown, in the embodiment of the present invention, the connecting assembly includes:

[0050] The connecting rod 44 is rotatably arranged on the fixing plate 41, one end of the connecting rod 44 is rotatably connected with a sleeve rod 45, and a threaded rod 415 is threadedly connected inside the sleeve rod 45;

[0051] The first bevel gear 46 and the second bevel gear 47 are both rotatably arranged inside the fixing plate 41, and the first bevel gear 46 and the second bevel gear 47 are meshed with each other;

[0052] The third bevel gear 48 and the internal bevel gear ring 49, the third bevel gear 48 is rotatably connected to the connecting rod 44, the internal bevel gear ring 49 is installed at one end of the sleeve rod 45, the third bevel gear 48 meshes with the internal bevel gear ring 49, and the third bevel gear 48 and the first bevel gear 46 are driven by a first transmission belt 410, so that the first bevel gear 46 rotates to drive the third bevel gear 48 to rotate;

[0053] The second transmission belt 411 is sleeved between the main motor 42 and the second bevel gear 47.

[0054] In the embodiment of the present invention, the resistance that the main motor 42 needs to overcome to drive the positioning screw 43 to rotate is less than the resistance that the main motor 42 needs to overcome to drive itself to rotate.

[0055] As Figures 1 to 5 shown, in the embodiment of the present invention, the adapter assembly includes:

[0056] The slot 412 is opened on the side wall of the positioning sleeve 31. A guide rod 413 is arranged inside the slot 412. A slider 414 is slidably arranged on the guide rod 413. One end of the threaded rod 415 is rotatably connected to the slider 414.

[0057] When the positioning assembly 4 is used, first connect the positioning sleeve 31 to the concrete-filled steel tube column through the locking assembly 3 to fix the concrete-filled steel tube column, that is: first sleeved the positioning sleeve 31 outside the concrete-filled steel tube column, and then drive the cylinder 33 to operate. Since all the cylinders 33 are synchronously connected by electrical signals, when one of the cylinders 33 operates, the other cylinders 33 will also work synchronously. Then the cylinder 33 will push the air rod 34 outwards until the fastening plate 35 contacts the side wall of the concrete-filled steel tube column. Through the clamping action of all the fastening plates 35, the clamping of the concrete-filled steel tube column can be realized.

[0058] Subsequently, the fixing plate 41 is placed on the ground, and the main motor 42 is driven to operate. Since the resistance that the main motor 42 needs to overcome to drive the positioning screw 43 to rotate is less than the resistance that the main motor 42 needs to overcome to drive itself to rotate, when the main motor 42 operates, it will first drive the positioning screw 43 to rotate. By rotating, the positioning screw 43 is inserted into the ground until the positioning screw 43 is inserted to the deepest position to fix the fixing plate 41. Subsequently, since the positioning screw 43 has moved to the deepest position and the positioning screw 43 itself is restricted by the thread formed by the inner wall of the ground surface, the positioning screw 43 cannot rotate. At this time, the operation of the main motor 42 will drive itself to start rotating. When the main motor 42 rotates itself, it will drive the second bevel gear 47 to rotate through the second transmission belt 411. The second bevel gear 47 will control the first bevel gear 46 to rotate synchronously through the meshing relationship. Furthermore, the first bevel gear 46 will drive the third bevel gear 48 to rotate through the first transmission belt 410. When the third bevel gear 48 rotates, it will control the sleeve rod 45 to rotate through the meshing relationship with the inner bevel gear ring 49. Then, the sleeve rod 45 will draw the threaded rod 415 into the inside of the sleeve rod 45 through the threaded fit relationship and control the slider 414 to slide to the lowest end of the slot 412, and use the sleeve rod 45 and the threaded rod 415 to tighten the entire locking assembly 3 to fix the concrete-filled steel tube column. Moreover, the setting of the slot 412 and the slider 414 enables the positioning assembly 4 to be positioned at different parts of the concrete-filled steel tube column according to different situations, and the adaptation effect is good.

[0059] As Figure 1 shown, in the embodiment of the present invention, a plurality of positioning support plates 5 are arranged on the side of the base 1, a bottom plate 6 is arranged at the bottom of the base 1, the positioning support plates 5 are connected to the bottom plate 6, and the bottom plate 6 is connected to the ground by screws.

[0060] In summary, when the earthquake-resistant pressure-dividing device for the concrete-filled steel tube column based on house design is used, first place the concrete-filled steel tube column in the connection groove 2 to achieve the preliminary positioning of the concrete-filled steel tube column. Subsequently, place the locking assembly 3 on the concrete-filled steel tube column and connect and fix it to the concrete-filled steel tube column. Then, use the positioning assembly 4 to connect the locking assembly 3 to the ground and tighten and lock it to fix the entire concrete-filled steel tube column. The fixing effect is good, and the entire fixing process does not require redundant manual operations and does not require the use of a large number of screws, which saves manpower and material resources and also saves a large amount of spare parts cost. It is time-saving and labor-saving, convenient to use, and has a high degree of automation.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
