Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template joint reduction tool. Background Art

[0002] In the construction of existing concrete structures, it is necessary to first set up steel bars, then support the formwork, and then pour the concrete. When supporting the formwork, due to the size limitation of the formwork, multiple formworks are often required to be spliced ​​and used. In addition, the inner and outer formworks of the wall need to be tightened by tension bolts to withstand the lateral pressure of the concrete and ensure that the spacing between the inner and outer formworks can meet the design requirements. Specifically, the construction process of concrete pouring is as follows: first set up the steel frame, and determine the installation position of the column and wall formwork outside the steel frame; then assemble the prefabricated formwork, and the prefabricated formwork is evenly distributed with several holes for installing tension bolts; then install wooden squares at equal intervals along the longitudinal direction on the outer surface of the formwork, and reserve the position of the holes; then assemble the column and wall formwork outside the steel frame, and insert the PVC sleeve into the reserved holes of the column and wall formwork; insert the tension bolts after the PVC sleeve is installed; install the secondary ribs along the horizontal direction on the outer surface of the wooden square, and the secondary ribs of the column and wall formwork are made of steel pipes, and the two adjacent steel pipes are fixed with tension bolts; finally, pour the concrete.

[0003] Due to the extensive use of formwork, common problems such as joint leakage and misalignment are faced during formwork support, which has always affected the quality of engineering construction and the work site environment. In addition, the joints between the formwork also lead to poor appearance quality of the concrete after forming, which requires manual leveling, which is time-consuming and labor-intensive.

[0004] The utility model patent with the authorization announcement number "CN216157171U" discloses a template joint anti-seepage device, which is provided with a limit plate to preliminarily fix the device, and a sealing plate, a reinforcement plate and a joint clamping plate are provided to form an I-shaped clamping structure to seal the joint between two adjacent templates, which can effectively solve the problem of leakage of slurry in the joints between adjacent templates; however, the device also has some defects when in use: the sealing plate is tightly against the inner side of the template to seal the joint and prevent seepage. After the concrete pouring is completed and the device and the template are disassembled, a gap will be formed in the concrete structure at the sealing plate, affecting the flatness of the cast structure. In addition, the joint anti-seepage device can only perform anti-seepage treatment on the template joints, and cannot reduce the template joints. The smaller the template joints, the higher the appearance quality of the concrete after forming.

[0005] In view of the above problems, it is urgent to develop a tool that can reduce the joints of the formwork and improve the surface flatness of the concrete structure. Summary of the invention

[0010] Furthermore, a docking square hole matching the docking square rod is opened at the center of the T-shaped rod, and the T-shaped rod and the docking square rod are connected by docking bolts.

[0014] Furthermore, the transverse alignment component includes a transverse alignment sleeve sleeved outside the tension bolt, one end of the transverse alignment sleeve is connected to an alignment ring plate, and the other end is connected to a connecting sleeve, and the connecting sleeve is threadedly connected to the internal threaded sleeve.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1:

[0029] Refer to the attached Figure 1-4 The template joint reduction tool shown in the figure includes an internal threaded sleeve 4 movably sleeved on a tension bolt 3, the tension bolt 3 is located between the outer template 1 and the inner template 2, and plays the role of tightening the inner template 1 and the outer template 2 to withstand the side pressure of concrete. The internal threaded sleeve 4 is threadedly connected with the tension bolt 3, and a docking square rod 5 is provided along the circumference of the outer side of the internal threaded sleeve 4, and a circle of first sliding grooves 401 for sliding of the docking square rod 5 is provided on the outer wall of the internal threaded sleeve 4 along the circumference. When the tension bolt 3 is used to connect the outer template 1 and the inner template 2, the internal threaded sleeve 401 is directly threadedly connected to the tension bolt 3, so that the internal threaded sleeve 4 is located between the outer template 1 and the inner template 2. The template joint reduction tool also includes a connection adjustment component for connecting and adjusting the distance between two adjacent docking square rods 5.

[0030] Specifically, the connection adjustment component includes a center sleeve 6, and two T-shaped rods 7 for connecting two adjacent docking square rods 5 are axially slidably connected inside the center sleeve 6. The two T-shaped rods 7 can only move axially inside the center sleeve 6 and cannot rotate. The end of the T-shaped rod 7 outside the center sleeve 6 is larger than the outer diameter of the center sleeve 6, so that the T-shaped rod 7 cannot completely fall into the center sleeve 6. In addition, the maximum moving distance of the T-shaped rod 7 in the center sleeve 6 is certain, which can be specifically achieved by using a certain length of slide rail and slider to cooperate, which will not be elaborated in this application. In order to reduce the distance between two adjacent templates, thereby realizing the function of reducing the template joint, a joint adjustment component is provided between the ends of the two T-shaped rods 7 outside the center sleeve 6.

[0031] Each T-shaped rod 7 has a docking square hole 701 in the center thereof that matches the docking square rod 5, and the T-shaped rod 7 is connected to the docking square rod 5 by a docking bolt 8, and threaded through holes 801 that match the docking bolts 8 are provided at positions corresponding to each other between the T-shaped rod 7 and the docking square rod 5. Pull the T-shaped rod 7 outward from the central sleeve 6, and at the same time, rotate the docking square rod 5 to make it correspond to the position of the docking square hole 701 on the T-shaped rod 7, insert the docking square rod 5 into the T-shaped rod 7, and when the T-shaped rod 7 is pulled to the maximum displacement, the two threaded through holes 801 on the T-shaped rod 7 and the docking square rod 5 correspond to each other, and screw the docking bolts 8 into the two bolt through holes 801, and the T-shaped rod 7 and the docking square rod 5 can be fixed. Two T-shaped rods 7 are used to connect and fix two adjacent butt-jointed square rods 5. Since the two T-shaped rods 7 are coaxial with the center sleeve 6, when the two T-shaped rods 7 are connected to the two adjacent butt-jointed square rods 5, the two connected butt-jointed square rods 5 can be aligned in the longitudinal direction.

[0032] Optionally, the seam adjustment component includes a first adjusting screw 9 and a second adjusting screw 10 respectively arranged on the two T-shaped rods 7, and the first adjusting screw 9 and the second adjusting screw 10 are connected by an adjusting sleeve 11. The first adjusting screw 9 is provided with a T-shaped rotating shaft 901 at one end close to the second adjusting screw 10, and the adjusting sleeve 11 is provided with a connecting nut 1101 threadedly connected to the first adjusting screw 9. Except for the connecting nut 1101 threadedly connected to the first adjusting screw 9, other parts of the adjusting sleeve 11 do not contact the first adjusting screw 9, the diameter of the second adjusting screw 10 is larger than the diameter of the first adjusting screw 9, and the second adjusting screw 10 matches the internal thread of the adjusting sleeve 11. In the initial state, the adjusting sleeve 11 is connected to the first adjusting screw 9 through the connecting nut 1101, which does not affect the movement of the two T-shaped rods 7. After the two T-shaped rods 7 are respectively connected to the corresponding docking square rods 5, the adjusting sleeve 11 is rotated so that the end of the adjusting sleeve 11 close to the second adjusting screw 10 is connected to the second adjusting screw 10. At this time, the connecting nut 1101 is sleeved outside the T-shaped rotating shaft 901 (the inner thread of the connecting nut 1101 does not contact the T-shaped rotating shaft 901). Continue to rotate the adjusting sleeve 11, and the end of the T-shaped rotating shaft 901 can be pulled by the connecting nut 1101 to move the first adjusting screw 9 toward the direction of the second adjusting screw 10, thereby pulling the two tension bolts 3 to move toward each other, so as to reduce the joint between the two adjacent templates. In order to achieve the rotational friction between the contact surface of the connecting nut 1101 and the T-shaped rotating shaft 901, a sliding plate for reducing friction or a lubricant is applied on the contact surface of the T-shaped rotating shaft 901 and the connecting nut 1101.

[0033] The template seam reduction tool in this embodiment is used for assembling wall templates. When the tension bolts 3 are used to connect the outer template 1 and the inner template 2, the internal threaded sleeve 401 is directly threaded onto the tension bolts 3 so that the internal threaded sleeve 4 is located between the outer template 1 and the inner template 2 to complete the assembly of a template.

[0034] When the adjacent templates are assembled, the connecting adjustment assembly is used to connect the docking square rods 5 on the two internally threaded sleeves 4. Specifically, the T-bar 7 is pulled outward from the center sleeve 6. At the same time, the docking square rod 5 is rotated to correspond to the position of the docking square hole 701 on the T-bar 7. The docking square rod 5 is inserted into the T-bar 7. When the T-bar 7 is pulled to the maximum displacement, the two threaded through holes 801 on the T-bar 7 and the docking square rod 5 correspond to each other. The docking bolts 8 are screwed into the two bolt through holes 801 to fix the T-bar 7 and the docking square rod 5.

[0035] Finally, by rotating the adjusting sleeve 11, first connect the adjusting sleeve 11 to the second adjusting screw 10, and then continue to rotate the adjusting sleeve 11, pull the end of the T-shaped rotating shaft 901 through the connecting nut 1101, so that the first adjusting screw 9 moves toward the second adjusting screw 10, thereby pulling the two tension bolts 3 to move toward each other, thereby reducing the joint between the two adjacent templates.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, in order to realize the alignment of two adjacent templates in the horizontal direction, each of the internally threaded sleeves 4 is provided with a horizontal alignment component for adjusting the horizontal position of the template, as shown in the attached Figure 5 and 6 shown.

[0038] Specifically, the transverse alignment component includes a transverse alignment sleeve 12, one end of which is welded and fixed with an alignment ring plate 13, the transverse alignment sleeve 12 and the alignment ring plate 13 are both sleeved outside the tension bolt 3, and the other end of the transverse alignment sleeve 12 is welded and fixed with a connecting sleeve 14, and a second thread groove 402 is axially provided on the outer wall of the internally threaded sleeve 4, and the connecting sleeve 14 is threadedly connected with the second thread groove 402. When the connecting sleeve 14 is moved to one end of the second thread groove 402 close to the alignment ring plate 13, the alignment ring plate 13 contacts the inner wall of the outer template 1 or the inner template 2. If they cannot contact, the position of the entire internally threaded sleeve 4 on the tension screw 3 is adjusted, so that the distance between the adjacent internally threaded sleeves 4 on the tension screw 3 and the outer template 1 or the inner template 2 is exactly the same, and then the longitudinal position is aligned by connecting the two butt square rods 5 with the T-bar 7, so that the lateral position alignment of the two adjacent templates can be achieved to avoid misalignment.
