Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a tooth joint notch positioning workpiece and a device. Background Art

[0002] Tooth joint is a masonry method used to leave joints in brick walls. When the masonry cannot be built at the same time, tooth joints are generally reserved at the joints to maintain the integrity and stability of the masonry. It is often used in the connection between structural columns and walls. The purpose is to make the connection between the wall and the structural column more firmly when casting the structural column, which is more conducive to earthquake resistance.

[0003] At present, the size of the tooth joint is mainly determined by the masonry skills of the plasterer and the layout of the wall bricks. Due to the construction workers' skills alone, the size of the tooth joint cannot be unified from top to bottom, and there are certain differences in the concave and convex parts, which affects the pouring quality of the structural column concrete; the size of the tooth joint also determines the brick arrangement distribution of the masonry construction. When there is a problem with the control of the tooth joint size, it will also affect the masonry quality of the entire wall and have a certain interference with the masonry structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a tooth joint notch positioning workpiece and device to address the deficiencies of the prior art.

[0005] The specific technical solutions are as follows:

[0006] A tooth joint groove positioning workpiece includes an annular reinforcement rod, a rotating sleeve, two threaded rods and a positioning rod. The annular reinforcement rod is arranged on a steel frame in the middle of the tooth joint. The rotating sleeve is rotatably connected to the inner side of the annular reinforcement rod. The two threaded rods are relatively arranged in the rotating sleeve. One end of the two threaded rods is slidably connected to the rotating sleeve along the length direction of the rotating sleeve. The other ends of the two threaded rods are threadedly connected to the annular reinforcement rod, and the threads of the two threaded rods are arranged in opposite directions. The positioning rod is sleeved on one end of the threaded rod away from the rotating sleeve.

[0007] Optionally, a limiting sliding groove is provided in the rotating sleeve in the same length direction as the rotating sleeve, and a guide sliding block is installed on the threaded rod to slide along the length direction of the limiting sliding groove.

[0008] Optionally, the annular reinforcement rod is also provided with two fixing clips, a clamp, a bolt and a nut, one end of the two fixing clips is rotatably connected to the annular reinforcement rod, and the other ends of the two fixing clips are rotatably connected to the clamp, the bolt passes through the two clamps in turn, and the nut is threadedly connected to the bolt, and the nut abuts against the relative outer sides of the two clamps.

[0009] Optionally, the fixing buckle is further provided with a hook for clamping the steel bar frame.

[0010] Optionally, a friction sleeve rotatably connected to the positioning rod is fixedly sleeved on the surface of the threaded rod close to one end of the positioning rod.

[0011] Optionally, a non-slip pad is bonded to a side of the positioning rod away from the threaded rod.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0025] The tooth joint notch positioning workpiece provided in the present invention refers to Figure 1 and Figure 2 , including an annular reinforcement rod 1, a rotating sleeve 2, two threaded rods 3 and a positioning rod 4. In this embodiment, the annular reinforcement rod 1 includes a rectangular frame 10 and extension blocks 100 installed on both sides of the rectangular frame 10. The rotating sleeve 2 is rotatably connected to the inner side of the rectangular frame 10 of the annular reinforcement rod 1. The two threaded rods 3 are relatively arranged in the rotating sleeve 2. One end of the two threaded rods 3 is slidably connected in the rotating sleeve 2 along the length direction of the rotating sleeve 2. The other ends of the two threaded rods 3 are threadedly connected to the extension block 100 of the annular reinforcement rod 1, and the threads of the two threaded rods 3 are oppositely arranged. The positioning rod 4 is sleeved on the end of the threaded rod 3 away from the rotating sleeve 2.

[0026] During construction, first fix the annular reinforcement rod 1 on the steel frame in the middle of the tooth joint, and then drive the rotating sleeve 2 to rotate. The rotating sleeve 2 drives the two threaded rods 3 to move to both sides respectively, and then continuously rotates the rotating sleeve 2 to drive the two positioning rods 4 to reach the positions of the masonry bodies to be built on both sides. A tooth joint size space is formed between the two positioning rods 4. The bricklayer lays the wall bricks according to the reserved space. This can effectively control the accuracy of the tooth joint size, so that the tooth joint size can be retained uniformly from top to bottom, avoiding differences, improving the masonry quality of the entire wall, and thus ensuring the quality of the subsequent concrete pouring of the structural columns.

[0027] In the present invention, reference is made to Figure 2 and Figure 3A limiting slide groove 20 is provided in the rotating sleeve 2 in the same length direction as the rotating sleeve 2, and a guide slider 31 is installed on the threaded rod 3 to slide along the length direction of the limiting slide groove 20. When the rotating sleeve 2 is rotated, the limiting slide groove 20 inside the rotating sleeve 2 drives the threaded rod 3 to rotate through the guide slider 31. One end of the threaded rod 3 is threadedly connected to the extension block 100 of the annular reinforcement rod 1, so that the two threaded rods 3 are displaced to both sides respectively.

[0028] Reference Figure 4 The annular reinforcement rod 1 is also provided with a fixing clip 11, a clamp 12, a bolt 13 and a nut 14. One end of the two fixing clips 11 is rotatably connected to the annular reinforcement rod 1, and the other end of the two fixing clips 11 is rotatably connected to the annular reinforcement rod 1. The clamp 12 is moved close to each other to tighten the steel frame. Then the bolt 13 is passed through the two clamps 12 in turn, so that the head of the bolt 13 abuts against one clamp 12, and then the nut 14 is rotated to thread the nut 14 on the bolt 13, and the nut 14 abuts against the relative outer side of the other clamp 12. In this way, the annular reinforcement rod 1 is firmly fixed to the steel frame in the middle of the tooth joint, effectively reducing the situation where shaking affects the positioning accuracy, and further making the tooth joint size retention uniform up and down, avoiding differences, and improving the masonry quality of the entire wall.

[0029] The fixing buckle 11 is also equipped with a hook 111 for clamping the steel frame. The hook 111 and the two fixing buckles 11 form a stable triangle, and the hooks 111 are all in contact with the steel frame, which can further reduce the displacement space of the steel frame, so that the steel frame is firmly clamped in the fixing buckle 11 and the hook 111.

[0030] A friction sleeve 32 is fixedly sleeved on the surface of one end of the threaded rod 3 near the positioning rod 4 and is rotatably connected to the positioning rod 4. The direction of the positioning rod 4 can be adjusted according to actual working conditions to facilitate the laying of wall bricks.

[0031] An anti-skid pad 33 is bonded to the side of the positioning rod 4 away from the threaded rod 3 , and the anti-skid pad 33 can increase the friction between the contact surface between the positioning rod 4 and the contacted object.

[0032] The outer surface of the rotating sleeve 2 is provided with anti-skid patterns 21 to increase the friction between the rotating sleeve 2 and the operator's contact surface, making it easier to drive the rotating sleeve 2 to rotate.

[0033] There are scales 22 on both sides of the surface of the rotating sleeve 2, which can determine the length of extension or contraction of the positioning rod 4 according to the scale of the rotation of the rotating sleeve 2, thereby further facilitating the control of the accuracy of the tooth joint size, so that the tooth joint size can be retained uniformly from top to bottom.

[0034] The present invention provides a tooth joint notch positioning device, comprising a plurality of tooth joint notch positioning workpieces, adjacent tooth joint notch positioning workpieces are connected by a hinge 6, and the two tooth joint notch positioning workpieces can be hinged together. The distance of the positioning rods 4 extended is adjusted according to the specific working conditions of the construction site, so that the two positioning rods 4 in one tooth joint notch positioning workpiece correspond to the concave part of the wall to be built, and the two positioning rods 4 in the other adjacent tooth joint notch positioning workpiece correspond to the concave part of the wall to be built. After this part is completed, the two positioning rods 4 can be moved at the same time. The tooth joint notch positioning workpiece is used to position the upper and lower parts of the wall to be stacked in the vertical direction; the number of tooth joint notch positioning workpieces can also be determined according to the height size of the tooth joint in actual working conditions, and these multiple tooth joint notch positioning workpieces are fixed on the steel frame at the same time, and each tooth joint notch positioning workpiece is adjusted to correspond to the concave and convex parts of the wall to be stacked. When the bricklayer stacks the walls on both sides of the tooth joint notch, he can directly carry out construction according to the position of the positioning rod 4; and the adjacent tooth joint notch positioning workpieces are connected by a hinge 6 for convenient storage.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
