Description

Technical Field

[0001] The utility model belongs to the technical field of building construction reinforcement equipment, and particularly relates to a prestressed reinforced concrete frame column device. Background Technique

[0002] The reinforced concrete structure is one of the most widely used structural forms at home and abroad. Due to design and construction defects, various damages or the need to improve service requirements, etc., a large number of engineering structures need to be reinforced. Prestressed reinforcement is a common reinforced concrete reinforcement technology. A prestressed concrete structure is one in which, before the structural member is subjected to external load, pressure is artificially applied to it in advance. The resulting prestressed state is used to reduce or offset the tensile stress caused by the external load, that is, by relying on the relatively high compressive strength of concrete to make up for the deficiency of its tensile strength, so as to achieve the purpose of delaying the cracking of the concrete in the tensile zone. A structure made of prestressed concrete is also called a prestressed reinforced concrete structure because the method of tensioning steel bars is used to achieve the precompression stress. The prestressed reinforced concrete frame column structure has many advantages: high load-bearing capacity, large stiffness, small cross-sectional size of components, appropriate concrete cover to improve the durability and fire resistance of the structure, and save maintenance costs during use;

[0003] However, in our country, the structural form adopted by most high-rise buildings is the reinforced concrete frame structure. The frame columns bear all the vertical loads and the additional loads caused by horizontal loads. With the vigorous development of prefabricated buildings, the application of precast reinforced concrete frame columns is becoming more and more extensive, and the types and models of frame columns required are also increasing continuously. The existing reinforced concrete frame columns tend to be single, and when constructing, it is time-consuming and laborious, requiring a large amount of manual labor input, with slow work efficiency and a single casting frame structure.

[0004] Therefore, those skilled in the art have proposed a prestressed reinforced concrete frame column device to solve the problems raised in the background technique. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a prestressed reinforced concrete frame column device to solve the problems of time-consuming and laborious, slow work efficiency, single casting frame structure, etc. in the prior art.

[0006] A prestressed reinforced concrete frame column device includes a frame column base. Above the frame column base, there is an assembly mechanism for constructing a reinforced concrete frame, and below the frame column base, there is a clamping mechanism for improving the fixing effect when prestressed steel bars are pulled.

[0007] Preferably, a plurality of fixing steel bars for constructing a reinforced concrete frame are provided above the frame column base, and the assembly mechanism includes a frame plate sleeved outside the fixing steel bars for fixing.

[0008] Preferably, steel wires are conductively arranged inside the frame plate, and a plurality of through holes for inserting steel wires to tie and fix steel bars are arranged on the surface of the frame plate.

[0009] Preferably, grooves are arranged at both the upper and lower ends of the frame plate.

[0010] Preferably, a fixing plate for pouring cement to construct a reinforced concrete frame is slidably arranged inside the groove.

[0011] Preferably, insertion columns are arranged at the outer ends of the frame plates, and limiting holes for cooperating with the insertion of the insertion columns are arranged at the other ends of the frame plates.

[0012] Preferably, the clamping mechanism includes a fixing component arranged below the base of the frame column. The fixing component includes a tightening screw rod, and two fixing clamp blocks for fixing and clamping one end of the prestressed steel bar to increase the pulling stability are screwed and connected to the outer side of the tightening screw rod.

[0013] Preferably, an adjusting nut for controlling the clamping operation of the fixing clamp block is connected to the outer end of the tightening screw rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The assembling mechanism provided in the utility model greatly improves the construction efficiency of the prestressed reinforced concrete frame column. When operating, the staff is more time-saving and labor-saving. Without investing too much labor, the main body of the frame column can be formed. Then, cement is poured and hardened. The frame plate in the assembling mechanism not only has the effect of disassembly and assembly, and can be assembled into a suitable size according to the required specifications of the reinforced concrete frame column. Then, the fixed steel bars of the frame column are tied by steel wires and passed through the through holes to complete the fixation. Moreover, grooves are provided at both the upper and lower ends of the frame plate, and the fixing plate can slide into the grooves to form the frame shape for pouring cement. The work efficiency is high, and to a certain extent, the manual labor consumption is greatly reduced, and the construction work is more time-saving and labor-saving.

[0023] The following further describes in detail the implementation mode of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0025] Embodiment 1: The present utility model provides a prestressed reinforced concrete frame column device, including a frame column base 1. Above the frame column base 1, there is an assembly mechanism 2 for constructing a reinforced concrete frame, and below the frame column base 1, there is a clamping mechanism 3 for improving the fixing effect when prestressing steel bars are pulled.

[0026] The assembly mechanism 2 greatly improves the construction work efficiency of the prestressed reinforced concrete frame column, and it is more time-saving and labor-saving for workers during operation. Without much labor input, the main body of the frame column can be formed, and then cement is poured and hardened. The frame plate 201 provided in the assembly mechanism 2 not only has the effect of disassembly and assembly. It can be assembled into a suitable size according to the specifications of the required reinforced concrete frame column, and then the fixed steel bars 101 of the frame column formed by tying with the steel wire 202 are passed through the through holes 203 to complete the fixation. Moreover, grooves 204 are provided at both the upper and lower ends of the frame plate 201, and the fixed plate 205 can slide into the grooves 204 to form the frame shape for pouring cement. The work efficiency is high, and to a certain extent, it greatly reduces the manual labor consumption, and the construction work is more time-saving and labor-saving.

[0027] The clamping mechanism 3 further improves the construction work performance of the device. When the prestressed steel bars are pulled, the cooperation of the tightening screw rod 301, the fixed clamping block 302 and the adjusting nut 303 provided in the clamping mechanism 3 can greatly improve the stability effect when the prestressed steel bars are pulled, and increase the protection safety.

[0028] Above the frame column base 1, there are multiple fixing steel bars 101 for constructing a reinforced concrete frame. The assembling mechanism 2 includes a frame plate 201 sleeved outside the fixing steel bar 101 for fixing.

[0029] Inside the frame plate 201, a steel wire 202 is conductively arranged. On the surface of the frame plate 201, there are multiple groups of through holes 203 for passing the steel wire 202 through to tie the fixing steel bar 101.

[0030] At the upper and lower ends of the frame plate 201, there are grooves 204.

[0031] Inside the groove 204, a fixing plate 205 for pouring cement to construct a reinforced concrete frame is slidably arranged.

[0032] At the outer end of the frame plate 201, there is a plugging column 206, and at the other end of the frame plate 201, there is a limiting hole 207 for cooperating with the plugging column 206 to insert.

[0033] As can be seen from the above, the assembling mechanism 2 includes a frame plate 201 sleeved outside the fixing steel bar 101 for fixing. The fixing steel bar 101 is arranged above the frame column base 1 and is mainly used to construct the outer shape of the reinforced concrete frame. At the upper and lower ends of the frame plate 201, there are grooves 204. Inside the groove 204, a fixing plate 205 is slidably arranged. The fixing plate 205 can slide into the groove 204 to form the frame shape for pouring cement, so as to harden and form.

[0034] When tying the fixing steel bar 101, the fixing steel bar 101 forming the frame column is tied through the through hole 203 by the steel wire 202, and then it can be fixed by rotating and tightening. Then, the fixing plate 205 is slid into the groove 204 to form a surface, and then the cement pouring work is carried out. And the prestressed steel bar is located inside the fixing steel bar 101. As the cement hardens and forms, the construction of the reinforced concrete frame column is completed.

[0035] Embodiment 2: The clamping mechanism 3 includes a fixing component arranged below the frame column base 1. The fixing component includes a tightening screw rod 301, and two fixing clamp blocks 302 for fixing and clamping one end of the prestressed steel bar to increase the pulling stability are screwed and connected outside the tightening screw rod 301.

[0036] The outer end of the tightening screw rod 301 is connected with an adjusting nut 303 for controlling the clamping work of the fixing clamp block 302.

[0037] As can be seen from the above, the clamping mechanism 3 mainly includes a fixing component arranged below the frame column base 1. The fixing component includes a tightening screw rod 301, fixing clamp blocks 302 and an adjusting nut 303. The fixing clamp blocks 302 are screwed and connected outside the tightening screw rod 301. The fixing clamp blocks 302 are mainly used to fix the prestressed steel bar, so as to increase the stability and prevent sliding during pulling.

[0038] The adjusting nut 303 is connected to the outer end of the tightening screw rod 301 and is mainly used to control the clamping operation of the fixed clamp block 302. When the adjusting nut 303 is twisted, it drives the tightening screw rod 301 to rotate, thereby driving the fixed clamp block 302 outside the tightening screw rod 301 to perform the clamping or loosening operation, improving the stability effect of the prestressed steel bar during pulling and increasing the protection safety.
