Description

Technical Field

[0001] The utility model relates to a stair construction tool, in particular to a stair step brick paving device. Background Art

[0002] Bricklaying plays a crucial role in staircase construction. Traditional staircase bricklaying methods rely primarily on manual labor, which is not only inefficient but also difficult to ensure the consistency of the size and position of each step. Especially when laying the riser bricks, construction workers need to expend considerable effort and time repeatedly fine-tuning their position to ensure perfect alignment with the tread bricks. This undoubtedly further complicates the construction process and significantly prolongs the overall project timeline.

[0003] Furthermore, the width of stair steps and the angle between risers and treads can vary greatly depending on the stair design, posing significant challenges to traditional bricklaying methods. Traditional bricklaying methods are unable to cope with this diversity, forcing construction workers to perform tedious measurements and adjustments based on the specific dimensions of each step. This process not only greatly increases the difficulty of bricklaying and makes it difficult to ensure accurate placement, but also seriously affects construction efficiency, adding unnecessary time and cost. Utility Model Content

[0004] The purpose of the utility model is to provide a stair step paving device to solve the problems of complex operation, poor accuracy and low efficiency of traditional stair step riser brick paving.

[0005] The utility model is implemented as follows: a stair step brick paving device, whose structure includes a base plate, a kick brick baffle and a limit plate arranged on the base plate, and a limit plate adjustment mechanism jointly arranged on the base plate and the limit plate; the base plate includes two parallel longitudinal plates and a support plate connecting the two longitudinal plates; the limit plate includes a horizontally arranged limit transverse plate, a limit vertical plate arranged at the lower end of the limit transverse plate, and sleeves respectively arranged at both ends of the limit transverse plate, and the two sleeves are each sleeved on one of the longitudinal plates; the limit plate adjustment mechanism includes an internal threaded tube arranged on the support plate and a screw arranged on the limit transverse plate and matched with the internal threaded tube.

[0006] Furthermore, two shaft seats are provided on the limiting horizontal plate, and the two shaft seats are arranged in parallel and spaced apart. The screw rod is passed through the two shaft seats, and a flange portion is provided on the screw rod section between the two shaft seats. The size of the flange portion is larger than the size of the through hole of the shaft seat.

[0007] Furthermore, the kick brick baffle includes two vertical plates arranged in parallel and spaced apart and a connecting plate connecting the two vertical plates.

[0008] Furthermore, ear plates are provided on both the longitudinal plate and the vertical plate, and adjusting bolts are passed through the ear plates of the longitudinal plate and the ear plates of the vertical plate.

[0009] Furthermore, a fixing bolt is provided on the sleeve.

[0010] Furthermore, a handle is provided at the outer end of the screw.

[0011] Furthermore, a limiting block is provided at the outer end of the longitudinal plate, and the limiting block is used to prevent the limiting plate from slipping off the longitudinal plate.

[0012] Furthermore, scale lines are provided on the longitudinal plate.

[0013] This new model can quickly complete the positioning of stair riser tiles, greatly shortening construction time and thus improving overall work efficiency. Construction workers no longer need to carry out tedious manual measurement and fine-tuning, and can achieve precise positioning through simple adjustments, greatly reducing labor intensity.

[0014] The utility model ensures that the position of the kick tiles is accurately adjusted by arranging scale lines and a limit plate adjustment mechanism on the longitudinal plate, thereby ensuring the consistency of the size and position of each step, and improving the overall aesthetics and construction quality of the stairs.

[0015] The limit plate of the utility model can slide on the longitudinal plate and be adjusted by the limit plate adjustment mechanism, so that the device can flexibly adapt to tread bricks of different widths. This design greatly enhances the versatility and adaptability of the device, making it widely applicable to various types of stair construction.

[0022] like Figure 1-Figure 3 As shown, the utility model includes a base plate arranged on the tread brick 1, a kick brick baffle and a limit plate arranged on the base plate, and a limit plate adjustment mechanism arranged on the base plate and the limit plate. The limit plate is used to be clamped on the outer edge of the tread brick 1 to limit the kick brick 2, limit the kick brick 2 to a predetermined position, and then fill concrete between the kick brick 2 and the stair 20.

[0023] The bottom plate includes two parallel longitudinal plates 4 and a support plate 5 connecting the two longitudinal plates 4 , wherein the support plate 5 is perpendicular to the longitudinal plates 4 .

[0024] The limit plate comprises a horizontal limit plate 3, a limit vertical plate 6 at the lower end of the limit plate 3, and sleeves 7 at the left and right ends of the limit plate 3. Each sleeve 7 is sleeved onto a longitudinal plate 4. The limit plate 3 slides on the longitudinal plate 4 via the sleeves 7 to adjust the position of the limit vertical plates 6 to the width of the tread tiles 1. The inner side of the limit vertical plate 6 contacts the outer edge of the tread tile 1. A limit block 8 is provided at the outer end of the longitudinal plate 4. The size of the limit block 8 is larger than the size of the through hole of the sleeve 7. The limit block 8 is used to prevent the limit plate from slipping off the longitudinal plate 4.

[0025] The limit plate adjustment mechanism is used to adjust the position of the limit plate on the base plate to accommodate tread tiles 1 of different widths. The limit plate adjustment mechanism includes an internally threaded tube 9 provided on the support plate 5 and a screw 10 provided on the limit cross plate 3. The screw 10 is threaded into the internally threaded tube 9. A handle 11 is provided at the outer end of the screw 10. Rotating the handle 11 drives the screw 10 to rotate, and the screw 10 rotates in the internally threaded tube 9 to complete the adjustment of the limit plate.

[0026] Two shaft seats 12 are provided on the limiting horizontal plate 3. The two shaft seats 12 are arranged in parallel and spaced apart. A through hole for passing the screw 10 is opened on the two shaft seats 12. The screw 10 is passed through the two shaft seats 12. A flange portion 13 is provided on the screw 10 section between the two shaft seats 12. The size of the flange portion 13 is larger than the size of the through hole of the shaft seat 12.

[0027] The kicker block includes two parallel, spaced-apart vertical plates 14 and a connecting plate 15 connecting the two vertical plates 14. The connecting plate 15 increases overall stability. Both the longitudinal plate 4 and the vertical plate 14 are provided with lugs 16, and adjustment bolts 17 are inserted through the lugs of both the longitudinal plate 4 and the vertical plate 14. The synergistic effect of the lugs 16 and the adjusting bolts 17 allows for flexible adjustment of the angle between the base plate and the kicker block, thereby adapting to staircase structures with different angles between the kicker blocks and the tread blocks, ensuring that the kicker block is in a vertical position when the base plate is placed on the tread blocks. When the base plate is securely placed on the tread blocks 1, the kicker block ensures that it remains in a vertical position, providing a strong guarantee for the precise laying of the kicker blocks 2.

[0028] A fixing bolt 18 is provided on the sleeve 7. The fixing bolt 18 is used to fix the limit plate and the longitudinal plate 4 after the position of the limit plate is adjusted to prevent the limit plate from being displaced due to external force or vibration during construction, thereby ensuring that the kicker brick 2 can always remain in the predetermined position.

[0029] Scale lines 19 are provided on the longitudinal plate 4. The distance from the inner side of the limiter plate 6 to the front end of the longitudinal plate 4 represents the predetermined position of the kicker brick. Using these scale lines, the position of the kicker brick can be quickly and accurately adjusted, ensuring that the kicker brick is laid precisely in the predetermined position. This not only avoids the time wasted on repeated measurements and adjustments in traditional methods, but also greatly improves the accuracy of brick laying.

[0030] When the present invention is used, the base plate is placed on the tread bricks, and the screw 10 is driven to rotate in the internal threaded tube 9 by rotating the handle 11, driving the limit plate to move on the longitudinal plate 4. After adjusting the limit plate to the predetermined position, the fixing bolt 18 is tightened to fix the limit plate, and then the angle between the base plate and the kick brick baffle is adjusted by adjusting the bolt 17. After it reaches the designed angle between the stair kick bricks and the tread bricks, the adjusting bolt 17 is tightened, and then the kick bricks are placed in front of the kick brick baffle. The construction workers tighten the limit plate to the outer end of the tread bricks, and then fill the space between the kick bricks and the building body with concrete to fix the kick bricks to complete the laying of the kick bricks.
