Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of block construction, in particular to a mortar joint thickness control tool for block construction. BACKGROUND

[0002] During block masonry construction, workers need to repeatedly correct the mortar joint thickness between blocks to ensure that the thickness error between each mortar joint is as small as possible. Uneven thickness will make it difficult for the completed wall to meet the masonry specification, which may result in apparent quality problems in the wall, or even wall collapse in severe cases.

[0003] In the current masonry specification, the mortar joint is required to be recessed into the block by a certain distance, and then the recessed part is filled to achieve an aesthetically pleasing external finish. However, the existing technical solutions for mortar joint thickness control are too complex and have little application value, and workers still rely on visual inspection and experience to perform masonry, which lacks standardization. SUMMARY

[0004] The present application provides a mortar joint thickness control tool for block construction, which solves the problem of complex structure and large size of existing mortar joint control tools.

[0005] The technical solution of the present application is as follows:

[0006] A mortar joint thickness control tool for block construction, comprising a hollow main body, the hollow main body is upwardly, leftwardly and rightwardly convex to form an upper support portion, a left support portion and a right support portion;

[0007] A first reinforcing rib is arranged at the midpoint of the upper support portion;

[0008] A second reinforcing rib in inverted V shape is arranged between the upper surface and the lower surface of the left support portion;

[0009] A third reinforcing rib in inverted V shape is arranged between the upper surface and the lower surface of the right support portion.

[0010] Further, a fourth reinforcing rib in V shape is arranged at the connection between the upper support portion and the left and right support portions and the lower surface of the hollow main body.

[0011] Further, the upper end of the second reinforcing rib is connected to the midline of the upper surface of the left support portion, and the lower end of the left rib of the second reinforcing rib is connected to the left edge of the lower surface of the left support portion.

[0012] Further, the third reinforcing rib is symmetrical to the second reinforcing rib about the midline of the hollow main body.

[0013] Further, the rib plate thickness of the third reinforcing rib is equal to the rib plate thickness of the second reinforcing rib.

[0014] The rib plate thickness of the fourth reinforcing rib is equal to the rib plate thickness of the first reinforcing rib.

[0015] Further, the rib plate thickness of the fourth reinforcing rib is twice the rib plate thickness of the third reinforcing rib.

[0016] Further, the upper end of the upper supporting part, the left end of the left supporting part, and the right end of the right supporting part are all semicircular arcs.

[0017] Further, the width of the upper supporting part, and the height of the left and right supporting parts are designed to be the thickness of the mortar joint.

[0018] Due to the adoption of the above technical solutions, the application has the following beneficial effects:

[0019] 1. The application has a simple structure and good supporting performance. In the application, the upper supporting part and the left and right supporting parts adopt similar hollow structures, and reinforcing ribs are added to the hollow structures to make them have good supporting performance. In the technical solution of the application, the left and right supporting parts mainly bear vertical loads, so the reinforcing ribs are designed in an inverted V shape to form stable triangular supports on the upper surface, so as to disperse the loads to both sides. Similarly, in the upper supporting part, the main function is to bear the horizontal extrusion, so it is designed as a horizontal transverse support to resist the horizontal force generated when the rubbing block is pressed.

[0020] 2. The application is provided with a V-shaped fourth reinforcing rib at the communication part of the upper, left, and right supporting parts to strengthen the integrity of the three supporting parts, so as to ensure that the stress of each part is relatively uniform, and to avoid the problem of inaccurate mortar joint thickness caused by the deformation of the tool due to the load deviation. In one embodiment of the application, the rib plate thickness of the fourth reinforcing rib and the first reinforcing rib is thicker, which can further optimize the above beneficial effects.

[0027] Based on the background art, existing tools for controlling mortar joint thickness are complex in structure or large in size, and therefore have limited application value. For the problems described in the background art, please refer to the appendix. Figure 1 ~Appendix Figure 3 This application provides a tool for controlling the thickness of mortar joints in masonry construction, including a hollow body 1. The hollow body 1 protrudes upward, to the left, and to the right to form an upper support 2, a left support 3, and a right support 4, respectively. A horizontal first reinforcing rib 5 is provided at half of the upper support 2. An inverted V-shaped second reinforcing rib 6 is provided between the upper surface and the lower surface of the left support 3. An inverted V-shaped third reinforcing rib 7 is provided between the upper surface and the lower surface of the right support 4.

[0028] See appendix Figure 3 In this application, multiple hollow blocks 1 are used together. When in use, the hollow blocks 1 are placed at the intervals between the blocks (the joints between the mortar joints) along the outer edge of the masonry wall, i.e., the outer edge of the hollow block coincides with the outer edge of the wall. For a single layer of blocks, the left and right edges of each middle block are supported by two hollow blocks 1. The left hollow block 1 is supported by the right support part 4, and the right hollow block 1 is supported by the left support part 3.

[0029] For the block layer to be laid (not the first layer), the specific steps are as follows: lay the blocks from left to right. For the edge blocks, place the upper support 2 horizontally towards the middle of the wall on the lower block. Then, place a hollow body 1 normally (upper support 2 facing upwards) at the corresponding position on the right side of the edge block. Apply mortar between the two hollow bodies 1, with a thickness slightly higher than the height of the support. Place the edge block between the two supports by kneading, and scrape off the mortar that is squeezed out. For the middle blocks, the laying method is similar to that of the edge blocks, but when applying mortar, apply mortar with a thickness slightly greater than the width of the upper support 2 to the right surface of the block on the left side. Then, similarly, use a kneading method to firmly secure the block between the two hollow bodies 1. The laying of the first layer of blocks is similar to that of the middle layer, except that the hollow bodies 1 at the edges need to be placed normally. After the laying is completed, wait for the mortar to set, that is, 10-12 hours later, to remove the hollow bodies 1. After removal, clean the hollow bodies 1, and they can be reused.

[0030] In a preferred embodiment of this application, a V-shaped fourth reinforcing rib 8 is provided on the lower surface of the hollow body 1 at the connection between the upper support 2 and the left support 3 and the right support 4. The V-shaped fourth reinforcing rib 8 at the connection between the upper, left, and right support 4 strengthens the integrity of the three support parts, thereby ensuring relatively uniform stress distribution on each part and avoiding inaccurate mortar joint thickness indication caused by tool deformation due to load offset.

[0031] In the embodiments described above, the upper end of the second reinforcing rib 6 is connected to the centerline of the upper surface of the left support portion 3, and the lower end of the left side rib of the second reinforcing rib 6 is connected to the left edge of the lower surface of the left support portion 3. That is, the second reinforcing rib 6 extends obliquely downwards to both sides, and the left and right side ribs are symmetrical about the middle of the second reinforcing rib 6.

[0032] In a preferred embodiment of the above embodiments, the third reinforcing rib 7 and the second reinforcing rib 6 are symmetrical about the centerline of the hollow body 1. This symmetrical structure helps to balance deformation and improve the overall integrity of the tool.

[0033] In a specific embodiment of the preferred embodiment described above, the thickness of the third reinforcing rib 7 is equal to the thickness of the second reinforcing rib 6; and the thickness of the fourth reinforcing rib 8 is equal to the thickness of the first reinforcing rib 5. The varying rib thickness helps to balance the load-bearing capacity at different locations and improves tool synergy.

[0034] In a specific embodiment of the preferred embodiment described above, the thickness of the fourth reinforcing rib 8 is twice the thickness of the third reinforcing rib 7. The increased thickness of both the fourth reinforcing rib 8 and the first reinforcing rib 5 further optimizes the resistance to deformation. (See appendix.) Figure 2 In the appendix Figure 2 In the figure, z is the thickness of the second rib, d is the thickness of the mortar joint, t is the thickness of the tool, h is the height of the upper support 2, and L is the total length of the bottom of the tool.

[0035] In a preferred embodiment of this application, the upper end of the upper support portion 2, the left end of the left support portion 3, and the right end of the right support portion 4 are all semi-circular arc-shaped. The dimensions of the semi-circular arc shape are not included in the dimensions of the support portion.

[0036] In the embodiments described above, the width of the upper support 2 and the heights of the left support 3 and right support 4 are designed to correspond to the mortar joint thickness. Specifications require the mortar joint thickness to be between 8mm and 12mm. In this application, the thickness of the rib plate of the second reinforcing rib 6 ranges from 1mm to 2mm, and the inward extension width of each support is consistent.

[0037] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0038] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
