Description

Technical Field

[0001] The invention relates to the field of building construction tools, in particular to a building roof plaster construction and smearing tool. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction, which is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction and decoration engineering construction, etc. The place where the construction work is carried out is called "construction site" or "construction site", also called construction site;

[0003] After the building frame structure is poured with concrete, it is necessary to carry out plaster construction, smearing and smoothing operations on the surface of the poured concrete. When carrying out the surface smearing and smoothing operations on the poured concrete, a smearing tool is generally used;

[0004] See also Figure 6 The plaster construction smearing tool provided in the related art comprises: a smearing plate 1 and a handle 25, wherein the smearing plate 1 is in a horizontal plane and is made by quantitatively cutting a steel plate with a smooth surface; a fixing plate 24 is provided at the center of the upper surface of the smearing plate 1, and a handle 25 is fixedly installed on the upper end of the fixing plate 24, the installed handle 25 is in a T-shape, and a wooden grip is provided on the upper end of the handle 25;

[0005] When using the plaster construction and smearing tool, the operator holds the wooden handle provided at the upper end of the handle 25, and then aligns the smearing plate 1 with the wall surface to be constructed. Then, the operator applies force to the handle position to push the smearing plate 1 to slide back and forth along the wall surface to be constructed, thereby evenly smearing the required plaster on the poured concrete surface, and completing the plaster construction and smearing operation.

[0006] The structure design of the plaster construction smearing tool is simple, and it is also convenient to use and assemble; however, the defects are also obvious. Due to the horizontal structure design of the smearing plate 1, the installed handle 25 is fixedly connected to the smearing plate 1, so the plaster construction smearing tool can only be used for horizontal wall surfaces to carry out good plaster construction smearing operations; and for some special construction sites, such as inwardly concave building roofs and outwardly convex building roofs, the smearing plate 1 with a horizontal straight structure design is difficult to directly apply force and action area to the building roof position of the special structure. Even if it can be used for roof smearing construction, only a part of the operation area of ​​the set smearing plate 1 is squeezed and contacted with the roof, and the effect is effective, and the construction personnel need to carry out multiple targeted operations, which is time-consuming and labor-intensive, greatly reducing the operation efficiency of the entire plaster construction smearing tool;

[0017] As a further solution of the present invention: an alignment rod is installed on the rotating shaft, and an alignment groove is opened inside the turntable at a position corresponding to the position where the alignment rod is installed on the rotating shaft.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Compared with the existing plaster construction and smearing tools, the building roof plaster construction and smearing tool has the following advantages:

[0020] First, it is provided with an applicator plate, a handle, ends respectively provided at both ends of the handle, a side slide frame movably connected to the inside of the applicator plate and the end heads, and a support slide frame movably connected to the applicator plate on both sides of the middle of the handle; a transmission assembly is provided at the position where the side slide frame is connected to the inside of the end heads, and at the position where the support slide frame is connected to the middle of the applicator plate, and a knob installed at the axial position of the transmission assembly replaces the handle originally fixedly connected to the applicator plate.

[0022] In addition, if the roof of the building to be constructed is concave upward, the knob position is rotated, and the transmission assembly is set to push the side slide frame to slide inside the end head or the support slide frame to slide inside the handle. For example, after the downward displacement distance of the support slide frame is greater than the downward displacement distance of the side slide frame, the inner side of the set smearing plate can form a convex surface, which fits the shape of the upward concave building roof to be constructed, and the concave building roof can be easily smeared and smoothed; so that the entire building roof plaster construction smearing tool can quickly and efficiently adapt to building roofs with various operating angles;

[0023] 2. The transmission assembly of the entire building roof plaster construction and smearing tool can accurately control the sliding displacement distance of the side slide and adjust the smear plate installed at the lower end of the side slide to a suitable arc angle position through the meshing action between the planetary gear and the gear ring and the gear segment, and it is not easy to loosen; in addition, the alignment rod and the alignment groove set in the later stage can ensure that the side slide will not be displaced even when subjected to a huge force, thereby achieving the stability of the side slide displacement distance and the arc angle position adjustment of the smear plate installed at the lower end of the side slide.

DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example

[0034] See also Figure 1 , Figure 2 and Figure 3 , a building roof plaster construction smearing tool provided in an embodiment of the present invention, the building roof plaster construction smearing tool comprises:

[0035] An smear plate 1 and a handle 7, wherein the smear plate 1 is used for surface smearing and leveling operations on building roofs; wherein, end caps 5 are respectively provided at both ends of the handle 7, and a mounting seat 2 is installed at the upper end of the smear plate 1 at the corresponding positions of the end caps 5 on both sides of the handle 7; the end cap 5 passes through a side slide 4, the lower end of the side slide 4 is mounted on the upper end of the mounting seat 2 by means of bolts 3, and the upper end of the side slide 4 is movably mounted inside the end cap 5; a transmission assembly is provided inside the end cap 5, and a knob 6 passes through the axial position of the transmission assembly; when the operator rotates the knob 6, the transmission assembly can be used to push the side slide 4 to move up and down inside the end cap 5;

[0036] The two sides of the middle of the handle 7 pass through the support carriage 8 respectively, and the lower end of the support carriage 8 is also installed on the mounting seat 2 set at the upper end of the smear plate 1 through the bolt 3; and the inside of the handle 7 is also installed with a transmission component and a knob 6 set at the axis position of the transmission component at the position where the support carriage 8 passes;

[0037] In addition, a gripping component is provided at the middle of the handle 7, and the gripping component is used to provide a gripping space for the operator, so that the operator can hold the handle to apply and smooth the roof of the building;

[0038] In the embodiment of the present invention, when using the building roof plaster construction and smearing tool, the operator grasps the component position in the middle of the handle 7, and then performs plaster construction and smearing operations on the building roof through the installed smearing plate 1;

[0039] During the construction process, the working angle direction of the smear plate 1 can be adjusted according to the angle position of the building roof;

[0040] For example, if the roof of the building to be constructed is convex upward, the side slide 4 is pushed to slide inside the end head 5 or the support slide 8 is pushed inside the handle 7 by rotating the knob 6. For example, after the upward displacement distance of the support slide 8 is greater than the upward displacement distance of the side slide 4, the inner side of the smear plate 1 can be formed into an arc surface, which fits the shape of the upward convex building roof to be constructed, and the smearing and smoothing operation can be easily performed on the convex building roof;

[0041] In addition, if the roof of the building to be constructed is concave upward, the side slide 4 is pushed to slide inside the end 5 or the support slide 8 is pushed inside the handle 7 by rotating the knob 6. For example, after the downward displacement distance of the support slide 8 is greater than the downward displacement distance of the side slide 4, the inner side of the smear plate 1 can be formed into a convex surface, which fits the shape of the upward concave building roof to be constructed, and the concave building roof can be easily smeared and smoothed.

[0042] See also Figure 1 In one embodiment of the present invention, the grip assembly includes a grip sleeve 10 and a baffle 9. The grip sleeve 10 is sleeved on the middle position of the outer side of the handle 7, and the baffles 9 are symmetrically installed on both sides of the grip sleeve 10; at the same time, the outer surface of the grip sleeve 10 is distributed and installed with anti-slip threads 11;

[0043] In the embodiment of the present invention, when the operator exerts force on the position of the grip assembly, the operator holds the grip sleeve 10, and the anti-skid thread 11 installed on the outer surface of the grip sleeve 10 is used to increase the static friction of the operator's hand on the grip sleeve 10 to prevent the operator's hand from slipping; and the baffles 9 arranged on both sides of the grip sleeve 10 can ensure that the operator's hand is not likely to fall off when holding the grip sleeve 10;

[0044] See also Figure 4 and Figure 5 In one embodiment of the present invention, a movable groove 12 is provided inside the side slide 4, a tooth segment 19 is installed on one side of the inner wall of the movable groove 12, one side of the tooth segment 19 is engaged with a transmission component, and the transmission component is located inside the end head 5;

[0045] Specifically, the transmission assembly includes a rotating disk 17 and a gear ring 15, the gear ring 15 is located on the outer side of the rotating disk 17, and a gap 13 is formed between the inner side of the gear ring 15 and the outer side of the rotating disk 17; at the same time, a main gear 20 is rotatably installed at the axis position of the rotating disk 17, a rotating shaft 21 is provided at the axis position of the main gear 20, and a knob 6 is provided at the top part of the rotating shaft 21; four sub-gears 18 are also installed in a ring-shaped distribution on the upper end surface of the rotating disk 17, and the outer side of the sub-gear 18 is meshed with the outer side of the main gear 20; in addition, the inner wall of the gear ring 15 is provided with internal teeth 16 in a ring-shaped distribution, and the inner side of the internal teeth 16 is meshed with the outer side of the sub-gear 18, and the outer side of the gear ring 15 is provided with external teeth 14 in a ring-shaped distribution, and the outer side of the external teeth 14 is meshed with the tooth segment 19 installed on the inner wall of the movable groove 12;

[0046] In the embodiment of the present invention, when the operator applies force to the position of the knob 6, the transmission assembly is used to push the side carriage 4 to slide and displace inside the end 5 to adjust the arc angle position of the smear plate 1 installed at the lower end of the side carriage 4. When the operator applies force to the position of the knob 6 to push the knob 6 to rotate, the rotation of the knob 6 will drive the rotating shaft 21 to rotate; when the rotating shaft 21 rotates, the main gear 20 will be driven to rotate;

[0047] Since the outer side of the main gear 20 is meshed with the outer side of the sub-gear 18, when the main gear 20 rotates, the sub-gear 18 is driven to rotate. Since the outer side of the sub-gear 18 is meshed with the inner teeth 16 installed on the inner wall of the gear ring 15, and there is a gap 13 between the inner side of the gear ring 15 and the outer side of the rotating disk 17, when the sub-gear 18 rotates, the gear ring 15 is driven to rotate on the outer side of the rotating disk 17.

[0048] When the turntable 17 rotates, the outer teeth 14 arranged on the outer side of the gear ring 15 mesh with the tooth segments 19 installed on the inner wall of the movable groove 12. Therefore, when the gear ring 15 rotates, it will push the side slide 4 to move up and down along the inside of the end 5, thereby realizing the adjustment and change of the arc angle position of the smear plate 1 installed at the lower end of the side slide 4;

[0049] See also Figure 4 and Figure 5 In the embodiment of the present invention, an alignment rod 22 is installed on the rotating shaft 21, and an alignment groove 23 is opened inside the rotating disk 17 at a position corresponding to the position where the alignment rod 22 is installed on the rotating shaft 21;

[0050] In the embodiment of the present invention, when the force is applied to the position of the knob 6 to push the rotating shaft 21 to rotate, the side slide 4 is driven to move up and down through the transmission assembly. For example, after the knob 6 is rotated to a suitable angle and the position of the displaced side slide 4 is adjusted appropriately, the rotating shaft 21 can be locked and fixed by inserting the alignment rod 22 movably installed on one side of the rotating shaft 21 into the alignment groove 23 opened at the corresponding designated position inside the turntable 17. This can prevent the operator from using the construction tool for applying the building roof in the next step. The force at the position of the smearing plate 1 is fed back to the side slide 4, causing the side slide 4 to loosen and shift in position.

[0051] The transmission assembly is configured to accurately control the sliding displacement distance of the side slide 4 and adjust the smear plate 1 installed at the lower end of the side slide 4 to a suitable arc angle position through the meshing action between the planetary gear and the gear ring 15 and the gear segment 19, and it is not easy to loosen; in addition, the alignment rod 22 and the alignment groove 23 configured in the later stage can ensure that the side slide 4 will not be displaced when subjected to a huge force, thereby achieving the stability of the adjustment of the displacement distance of the side slide 4 and the arc angle position of the smear plate 1 installed at the lower end of the side slide 4;
