Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and in particular to a steel bar auxiliary installation device used in building construction. Background Art

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are the primary structures in buildings or structures responsible for bearing horizontal loads caused by wind or earthquakes. Typically constructed of reinforced concrete, their core function is to prevent shear failure. As such, shear walls effectively resist horizontal forces such as wind and earthquakes, ensuring the stability and safety of buildings under these external forces.

[0003] Shear wall construction mainly includes the following series of steps: first is measurement and layout, which requires accurate determination of the position and size of the shear wall, and precise measurement and marking at the construction site; next is steel bar binding, which requires bending and cutting the steel bars according to design requirements, and then binding them into specific shapes and structures to enhance the strength of the shear wall; then, formwork is supported, and the constructed formwork must be stable and flat to ensure that there will be no deformation or leakage during concrete pouring; then, concrete pouring is carried out, and the mixed concrete is poured into the formwork. During the pouring process, attention must be paid to its uniformity and density to prevent the occurrence of voids or honeycomb structures; then comes the vibration stage, using vibrating tools such as vibrating rods to make the concrete denser and remove the bubbles in it, thereby improving the quality of the concrete; finally, maintenance, after the concrete is poured, the concrete is kept moist by watering, covering, etc., so that it reaches the design strength within the specified time.

[0004] During the reinforcement binding process of shear wall construction, vertical reinforcement is more likely to shift, which in turn causes the spacing of the vertical reinforcement groups to not meet the requirements, seriously affecting the bearing capacity of the shear wall. The main reasons for the easy shift of vertical reinforcement are as follows:

[0005] Impact force of concrete pouring: When pouring concrete, the impact force of the falling concrete may cause the vertical steel bars to move.

[0006] Collision during construction: At the construction site, people may accidentally collide with vertical steel bars while walking or carrying materials, causing them to shift in position.

[0007] Insecure tying: If the number of tying points for the steel bars is insufficient, the tying method is incorrect, or the strength of the tying material is insufficient, the vertical steel bars may not be effectively fixed, making them prone to displacement.

[0008] Impact of formwork installation and removal: During the installation and removal of the formwork, if the operation is improper, it may push or pull the vertical steel bars, causing their position to change.

[0009] Impact when vibrating concrete: When vibrating concrete, the vibrating rod may directly contact the vertical steel bars, causing them to deflect.

[0010] In summary, it is essential to address the issue of vertical reinforcement offset during shear wall construction. Failure to effectively address this issue will compromise the quality and safety of the shear wall and threaten the structural stability of the building. Utility Model Content

DETAILED DESCRIPTION

[0037] Please refer to Figure 1-Figure 5 , a steel bar auxiliary installation device used in construction construction includes: a first positioning component, including a first positioning bar 1 and a second positioning bar 2 arranged in parallel and at intervals, the first positioning bar 1 and the second positioning bar 2 have opposite sides respectively provided with a first sliding groove 5 and a second sliding groove 6, and the first sliding groove 5 and the second sliding groove 6 both extend along the first direction, the bottom of the first sliding groove 5 and the bottom of the second sliding groove 6 respectively pass through the first positioning bar 1 and the second positioning bar 2; a second positioning component, including a first sliding block 7, a second sliding block 8 and a first tensioning screw 3, the first sliding block 7 and the second sliding block 8 are both provided with through holes, the first sliding block 7 and the second sliding block 8 are respectively movably arranged in the first sliding groove 5 and the second sliding groove 6, and the through hole of the first sliding block 7 and the through hole of the second sliding block 8 are opposite, the first tensioning screw 3 passes through the through holes of the first sliding block 7 and the second sliding block 8 at the same time, and And the first pair of pulling screws 3 on the outside of the above-mentioned first sliding block 7 and the above-mentioned second sliding block 8 are threadedly engaged with a first locking nut; wherein the number of the above-mentioned second positioning components is multiple, and the multiple second positioning components are evenly spaced along the first direction; the first adjusting screw 12 is rotatably set on the above-mentioned first positioning bar 1, and is simultaneously threadedly engaged with the multiple first sliding blocks 7. When the above-mentioned first adjusting screw 12 rotates, in the first direction, the moving distance values of the multiple first sliding blocks 7 increase or decrease in sequence, and the moving distance values of the multiple first sliding blocks 7 constitute an arithmetic progression one; and the second adjusting screw 13 is rotatably set on the above-mentioned second positioning bar 2, and is simultaneously threadedly engaged with the multiple second sliding blocks 8. When the above-mentioned second adjusting screw 13 rotates, in the first direction, the moving distance values of the multiple second sliding blocks 8 increase or decrease in sequence, and the moving distance values of the multiple second sliding blocks 8 constitute an arithmetic progression two, and the tolerances of the above-mentioned arithmetic progression one and the above-mentioned arithmetic progression two are equal.

[0038] When the present application is actually used, it is positioned at the position where the vertical reinforcement is to be installed, and the first positioning strip 1 and the second positioning strip 2 are located on opposite sides of the installation position. According to the design position of the design drawing, by synchronously adjusting the first adjusting screw 12 and the second adjusting screw 13, multiple first tensioning screws 3 are prompted to move synchronously until the spacing between adjacent first tensioning screws 3 meets the design requirements of the drawing, and then the vertical reinforcement is installed one by one. The first tensioning screw 3 has a supporting effect on one of the side edges of the vertical reinforcement, preventing the vertical reinforcement from shifting, avoiding the problem of the spacing of the reinforcement group (composed of multiple vertical reinforcements) not meeting the requirements due to the vertical reinforcement shift, and is conducive to ensuring the bearing performance of the shear wall after casting.

[0039] In addition, based on the above positioning, another set of steel bar auxiliary installation devices can be installed (two sets arranged vertically). The two sets of auxiliary installation devices are distributed in a cross shape, so that the re-installed steel bar auxiliary installation device can be against the other side of the vertical steel bar, that is, the two sets of auxiliary installation devices form a multi-directional support for the vertical steel bar, which greatly reduces the probability of displacement of the vertical steel bar and is more practical.

[0040] Specifically, to ensure that the movement distances of the plurality of first sliding blocks 7 form an arithmetic progression when the first adjusting screw 12 rotates, threads of different sizes are provided on the first adjusting screw 12 to accommodate the corresponding sliding of the plurality of first sliding blocks 7. Similarly, the second adjusting screw 13 also adopts the same design as the first adjusting screw 12.

[0041] It is worth noting that when the first adjusting screw 12 and the second adjusting screw 13 are rotated and adjusted, the moving distances of the first sliding block 7 and the second sliding block 8 on both sides of the same tensioning screw are equal, so as to avoid the situation where the moving distances at both ends of the tensioning screw are unequal, which makes this application impossible to implement.

[0042] In some embodiments of the present invention, the first positioning strip 1 and the second positioning strip 2 are both provided with an L-shaped groove 14, one end of the L-shaped groove is connected to the first sliding groove 5 or the second sliding groove 6, and the other end of the L-shaped groove 14 passes through the side of the first positioning strip 1 or the second positioning strip 2.

[0043] Among them, any one of the above-mentioned first sliding blocks 7 and any one of the above-mentioned second sliding blocks 8 are provided with an L-shaped slider, and the above-mentioned L-shaped slider can be movably set in the above-mentioned L-shaped slide groove 14, and the end of the above-mentioned L-shaped slider 16 away from the above-mentioned first sliding block 7 or the above-mentioned second sliding block 8 passes through the slot of the above-mentioned L-shaped slide groove, and is provided with a sliding seat 9, and the above-mentioned sliding seat 9 is provided with a threaded hole that is threadedly matched with the above-mentioned first adjusting screw 12 or the above-mentioned second adjusting screw 13.

[0044] In the above embodiment, the L-shaped slider 16 fits tightly within the L-shaped slot 14. When the first adjusting screw 12 or the second adjusting screw 13 rotates, it drives the sliding seat 9 to move in the first direction. The sliding seat 9, with the help of the L-shaped slider 16, drives the first sliding block 7 or the second sliding block 8 to slide in the first direction, thereby achieving the spacing adjustment of the screw assembly (the plurality of first tension screws 3).

[0045] It is worth noting that the multiple sliding seats 9 on the first adjusting screw 12 have the same appearance, and the main difference lies in the specifications of the threaded holes to accommodate the adaptive sliding of the multiple sliding seats 9. Similarly, the multiple sliding seats 9 on the second adjusting screw 13 also adopt the same design.

[0046] In some embodiments of the present invention, the first adjusting screw 12 and the second adjusting screw 13 are both sleeved with two second locking nuts 15 , and the second locking nuts 15 are used to clamp one of the sliding seats 9 .

[0047] In the above embodiment, after the first adjusting screw 12 or the second adjusting screw 13 is rotated and adjusted, in order to prevent the first adjusting screw 12 and the second adjusting screw 13 from loosening, the two second locking nuts 15 clamp the sliding seat 9, which is beneficial to ensure the stability of the device when in use.

[0048] In some embodiments of the present invention, the first tensioning screw 3 is arranged along the second direction, and the first direction is perpendicular to the second direction.

[0049] In the above embodiment, the first tensioning screw rods 3 are arranged along the second direction, thereby facilitating the movement adjustment of the first tensioning screw rods 3 along the first direction.

[0050] In some embodiments of the present invention, the first positioning bar 1 and the second positioning bar 2 are both provided with a rotating seat 10 , and the rotating seat 10 is used for rotating with the first adjusting screw 12 or the second adjusting screw 13 .

[0051] In the above embodiment, the rotating seat 10 is used to connect the first positioning bar 1 with the first adjusting screw 12, or to connect the second positioning bar 2 with the second adjusting screw 13, so that the first adjusting screw 12 can rotate on the first positioning bar 1 and the second adjusting screw 13 can rotate on the second positioning bar 2, so as to facilitate the movement adjustment of the sliding seat 9.

[0052] Specifically, the first and second adjusting screws 12, 13 each have two rotating seats 10, one at each end. Each rotating seat 10 is a square block with a through hole (for the first and second adjusting screws 12, 13 to pass through). An annular block is positioned within the through hole. The first and second adjusting screws 12, 13 are each provided with an annular groove that allows for rotational engagement with the annular block.

[0053] In some embodiments of the present invention, the reinforcement auxiliary installation device further includes a second tensioning screw 4 , and the second tensioning screw 4 is used to detachably connect the first positioning bar 1 and the second positioning bar 2 .

[0054] In the above embodiment, the second tensioning screw 4 connects the first positioning bar 1 and the second positioning bar 2 into a whole, making the overall structure of the device more stable. In addition, the second tensioning screw 4 can realize the disassembly of the first positioning bar 1 and the second positioning bar 2, which is convenient for storage.

[0055] In some embodiments of the present invention, an adjustment seat 11 is provided at the end of the first adjusting screw 12 and the second adjusting screw 13, the diameter of the adjustment seat 11 is larger than that of the first adjusting screw 12 or the second adjusting screw 13, and the outer ring surface of the adjustment seat 11 is provided with anti-slip grooves.

[0056] In the above embodiment, the first adjusting screw 12 or the second adjusting screw 13 can be more easily adjusted by twisting the adjusting seat 11. The anti-slip pattern design can effectively prevent slipping during rotation and has strong practicality.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
