Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to a stirrup binding pre-positioning device. Background Art

[0002] Stirrups are used to provide shear strength in inclined sections and connect the main reinforcement bars with the reinforced concrete frame in the compression zone. They are categorized as single-leg stirrups, open rectangular stirrups, closed rectangular stirrups, diamond-shaped stirrups, polygonal stirrups, crisscross stirrups, and circular stirrups. Stirrups are most commonly found in building construction, serving as an essential component of various support beams. When several stirrups are used to fix the long steel bar, they are placed in sequence on the outside of the long steel bar, so that the spacing between the stirrups on the outside of the long steel bar cannot be guaranteed. In order to increase the shear strength of the inclined section of the long steel bar, it is necessary to arrange the stirrups on the outside of the long steel bar at equal intervals, so that the spacing between the stirrups on the outside of the long steel bar can be measured with a ruler, that is, the spacing between the stirrups needs to be measured once a stirrup is fixed, which makes the workload of the operator very large. Due to the large workload, in actual operation, the operator cannot measure one by one with a ruler, but relies on feeling to control the spacing between two adjacent stirrups, which makes the spacing between the stirrups have errors, which is not conducive to ensuring the quality of stirrup bundling. Therefore, a stirrup bundling pre-positioning device is needed to meet the needs. Utility Model Content

[0003] The utility model aims to solve the defect in the prior art that the distance between two adjacent stirrups outside the long steel bar cannot be pre-positioned, and proposes a stirrup binding pre-positioning device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A stirrup binding pre-positioning device is designed, comprising a cylinder, in which two threaded rods are symmetrically and threadedly inserted, and a positioning assembly is fixed to one end of the two threaded rods that protrude from the cylinder. The positioning assembly comprises a connecting support plate, the center of which is fixed to the top end of the threaded rod outside the cylinder, and two positioning plates are symmetrically fixed to the connecting support plate.

[0006] Preferably, the positioning plate is an inverted L-shaped structure.

[0007] Preferably, a lubrication mechanism is provided on the cylinder.

[0008] Preferably, the lubricating mechanism includes a sponge, which is fixed on the inner wall of the cylinder between the two threaded rods. An oiling component is fixed through the cylinder, and the sponge is in contact with the oiling component.

[0009] Preferably, the sponge is an oil-absorbing sponge.

[0010] Preferably, the oiling assembly includes an oil inlet pipe, which passes through and is fixed on the sponge, one end of which is in contact with the sponge, and a one-way valve is fixed on the oil inlet pipe outside the cylinder.

[0011] Preferably, an inserting cylinder is sealed and inserted on one end of the oil inlet pipe away from the sponge, and an air bag ball is connected and fixed on the inserting cylinder.

[0012] Preferably, a connecting rope is fixed on both the oil inlet pipe and the insertion cylinder.

[0013] The utility model proposes a stirrup binding pre-positioning device, which has the beneficial effect that: when in use, the stirrup binding pre-positioning device can limit the distance between two adjacent stirrups within a preset distance. After the movable stirrup is fixed on the long steel bar, the cylinder is pulled to quickly pull out the stirrup binding pre-positioning device, which can accurately limit the distance between two adjacent stirrups for the operator and is simple to operate and saves time.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1 、 2 , 3, 5 and 6, a stirrup binding pre-positioning device, comprising a cylinder 1, in which two threaded rods 2 are symmetrically and threadedly inserted. By twisting the two threaded rods 2, the length of the two threaded rods 2 protruding from the cylinder 1 can be adjusted, thereby adjusting the distance between the two positioning components, thereby meeting different requirements for the spacing between two adjacent stirrups;

[0023] A positioning assembly is fixed on one end of the two threaded rods 2 that leak out of the cylinder 1. The positioning assembly includes a connecting support plate 3. The center of the connecting support plate 3 is fixed on the top of the threaded rod 2 outside the cylinder 1. The connecting support plate 3 is an inverted U-shaped structure. Two positioning plates 4 are symmetrically fixed on the connecting support plate 3. When the two positioning plates 4 are in contact with the stirrups, the force on the support plate 3 and the cylinder 1 is more evenly distributed, thereby ensuring that the fixation between the support plate 3 and the cylinder 1 and the fixation between the positioning plate 4 and the support plate 3 will not be damaged. In addition, the positioning plate 4 is an inverted L-shaped structure. When the inverted L-shaped positioning plate 4 is in use, after the two adjacent stirrups are fixed on the long steel bar, the stirrup bundling pre-positioning device can also be easily pulled out.

[0024] When in use, the two positioning plates 4 at one end of the cylinder 1 are clamped on the fixed stirrups, the cylinder 1 is straightened, and the movable stirrups are moved along the long steel bars to a position in contact with the two positioning plates 4 at the other end of the cylinder 1. This can limit the distance between two adjacent stirrups to within a preset distance. After the movable stirrups are fixed on the long steel bars, the cylinder 1 is pulled, and the stirrup binding pre-positioning device can be quickly pulled out, which can not only accurately limit the distance between two adjacent stirrups for the operator, but also is simple to operate and saves time.

[0025] Example 2: In Example 1, since the two threaded rods 2 and the cylinder 1 are threaded, it is necessary to regularly lubricate the two threaded rods 2 and the cylinder 1 to ensure smooth use between the two threaded rods 2 and the cylinder 1. During maintenance, the two threaded rods 2 need to be completely unscrewed and lubricated, which is inconvenient for maintenance. Figure 2 、 3, 4 and 6, as another preferred embodiment of the present invention, the difference from embodiment 1 is that a lubricating mechanism is provided on the cylinder 1, the lubricating mechanism includes a sponge 5, and the sponge 5 is an oil-absorbing sponge. The sponge 5 is fixed on the inner wall of the cylinder 1 between the two threaded rods 2, and an oiling component is fixed through the cylinder 1. The sponge 5 and the oiling component are in contact with the oiling component. The oiling component can be used to add lubricating oil to the inside of the cylinder 1 and be absorbed and temporarily stored by the oil-absorbing sponge. When the two threaded rods 2 squeeze the oil-absorbing sponge, the lubricating oil in the oil-absorbing sponge will be squeezed out, and by inverting the cylinder 1, the lubricating oil can flow to the gap between the two threaded rods 2 and the cylinder 1 respectively, and then when the threaded rod 2 rotates afterwards, the lubricating oil is smeared on the threaded rod 2 and the cylinder 1, so that the two threaded rods 2 and the cylinder 1 can be maintained easily.

[0026] The oiling assembly includes an oil inlet pipe 6, which passes through and is fixed on the sponge 5. One end of the oil inlet pipe 6 is in contact with the sponge 5. A one-way valve 7 is fixed on the oil inlet pipe 6 outside the cylinder 1. The setting of the one-way valve 7 allows the lubricating oil to enter the cylinder 1 through the oil inlet pipe 6, and the lubricating oil can only enter but not exit, and will not cause waste of the lubricating oil absorbed in the sponge 5. A plug-in cylinder 8 is sealed and inserted on the end of the oil inlet pipe 6 away from the sponge 5. An airbag ball 9 is connected and fixed on the plug-in cylinder 8. The airbag ball 9 can add the lubricating oil smoothly through the oil inlet pipe 6 to the sponge 5 in the cylinder 1. A connecting rope 10 is fixed on the oil inlet pipe 6 and the plug-in cylinder 8. The use of the connecting rope 10 can avoid the loss of the airbag ball 9.

[0027] During use, when it is necessary to lubricate and maintain the two threaded rods 2 and the cylinder 1, pull the airbag ball 9 out from the oil inlet pipe 6 through the insertion tube 8, add lubricating oil into the airbag ball 9, keep the insertion tube 8 on the airbag ball 9 facing upward, press the insertion tube 8 back onto the oil inlet pipe 6, then turn the cylinder 1, pinch the airbag ball 9, let the lubricating oil in the airbag ball 9 be squeezed into the cylinder 1 through the insertion tube 8 and the oil inlet pipe 6 and absorbed by the sponge 5, twist the two threaded rods 2, let the two threaded rods 2 squeeze the sponge 5, the lubricating oil in the sponge 5 is squeezed out, then repeatedly turn the cylinder 1, let the lubricating oil flow into the gap between the two threaded rods 2 and the cylinder 1, then twist the two threaded rods 2 in the opposite direction, let the lubricating oil be smeared on the two threaded rods 2 and the cylinder 1, and then lubricate and maintain the two threaded rods 2 and the cylinder 1.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
