Description

Technical Field

[0001] The utility model relates to the field of construction, and particularly refers to a tightening tool for quickly improving the quality of formwork joints in a portable manner. Background Art

[0002] Fair-faced concrete is concrete that directly uses the natural texture after concrete forming as the finishing effect. It is cast in one go and does not require any exterior decoration. Because of its excellent decorative effect, it is also called decorative concrete. Since it directly uses the natural surface of the cast-in-place concrete as the decorative effect, it is different from ordinary concrete. Therefore, it is required that its surface be flat and smooth, with no obvious color difference on the surface, clear and distinct edges and corners, and no damage or pollution. However, during the splicing process of fair-faced concrete formwork, if the formwork joints cannot be tightly closed, water loss and slurry leakage are likely to occur at the joints after the fair-faced concrete wall is poured, which will seriously affect the forming quality of the fair-faced concrete wall. Therefore, measures are needed to solve the problem of loose splicing between formworks. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a tightening tool for quickly improving the quality of formwork joints in a portable manner, so as to solve the problem that the existing formwork joints are not tightly spliced, resulting in the concrete flowing out from the joints after pouring.

[0004] The technical solution for realizing the above purpose is: a tightening tool for quickly improving the quality of formwork joints in a portable manner, comprising:

[0005] A connecting piece placed at the edge of the formwork;

[0006] A telescopic pulling arm is hinged to the end of the connecting piece;

[0007] A plurality of outer joint rods installed on the formwork and arranged close to the edge of the formwork, and the outer joint rods are hinged to the pulling arm;

[0008] On the side close to the edge of the formwork of the corresponding connecting pieces connected by tying on adjacent two formworks, an upper turnbuckle fastener is installed. The turnbuckle fastener can adjust the length, and by adjusting the length, the corresponding connecting piece is tightened, and then the formwork is tightened through the pulling arm and the outer joint rod.

[0009] The technical solution of the utility model is further improved in that: a rotating shaft for movably connecting with the connecting piece is provided at the end of the pulling arm.

[0010] The technical solution of the utility model is further improved in that: an outer rod connection hole sleeved on the surface of the outer joint rod is provided on the pulling arm.

[0011] The further improvement of the technical solution of the present utility model lies in that: the pulling boom includes a first arm tube and a second arm tube partially inserted into the first arm tube, and the length of the inserted part of the second arm tube and the first arm tube is adjustable;

[0012] An arm boom fixing torsion is connected to the end of the first arm tube, and the arm boom fixing torsion fixes the first arm tube and the second arm tube after the positions of the first arm tube and the second arm tube are adjusted.

[0013] The further improvement of the technical solution of the present utility model lies in that: fixing bolts are threadedly connected to opposite sides of the turnbuckle fastener, and the fixing bolts are installed on one side of the connecting member close to the edge of the formwork.

[0014] The further improvement of the technical solution of the present utility model lies in that: the turnbuckle fastener is perpendicular to the connecting member.

[0015] The further improvement of the technical solution of the present utility model lies in that: both ends of the connecting member are semicircularly arranged.

[0016] The further improvement of the technical solution of the present utility model lies in that: the pulling boom is arranged obliquely.

[0017] The further improvement of the technical solution of the present utility model lies in that: the outer rod of the joint is cylindrical and perpendicular to the surface of the wall formwork.

[0018] Using the above technical solution, the technical effects achieved by the present utility model compared with the prior art are:

[0019] The present utility model provides a portable and fast squeezing tool for improving the joint quality of formworks. After the outer rod of the joint is installed on the wall formwork, it can better apply a force to the wall formwork, and the wall formworks are pulled and spliced together by the turnbuckle fastener, making their contact closer, reducing the seepage of slurry from the joint after the wall is poured with cement, reducing the construction risk of the concrete wall, and reducing the labor and economic costs such as the repair of the fair-faced wall surface in the later stage.

[0020] By twisting and adjusting the turnbuckle fastener to tighten the connecting member, the pulling boom pulls the outer rod of the joint. Using the turnbuckle fastener can effectively reduce the dependence on manpower and make the wall move more smoothly without skew.

[0021] Through the telescoping of the pulling boom, the length can be adjusted arbitrarily according to the distance of the outer rod of the joint, so that the pulling boom can better approach the outer rod of the joint, and the pulling boom can be driven to adjust the direction through the rotating shaft.

Place the squeezing tool on the outer joint rod 2, and then by rotating the turnbuckle fastener 4, use the turnbuckle fastener 4 to pull the pulling arm bracket 3, so that it transmits the pulling force to the outer joint rod 2, thereby pulling two formworks closer to each other through the outer joint rod 2 until the edges of the formworks are closed.

[0031] Preferably, as Figure 1 , Figure 2 shown, the pulling arm bracket 3 can be placed on the outer joint rod 2 to obtain a fixed position.

[0032] Furthermore, the pulling arm bracket 3 can be telescopic and its length can be adjusted arbitrarily according to needs, so that the pulling arm bracket 3 can better approach the outer joint rod 2.

[0033] Referring to Figure 3 , in a specific embodiment of the present utility model, a rotating shaft 5 for movably connecting with the connecting member 1 is provided at the end of the pulling arm bracket 3.

[0034] Furthermore, as Figure 3 shown, the rotating shaft 5 can rotate in the connecting member 1, so that the pulling arm bracket 3 can adjust its direction.

[0035] Referring to Figure 3 , in a specific embodiment of the present utility model, an outer rod connecting hole 6 sleeved on the surface of the outer joint rod 2 is provided on the pulling arm bracket 3.

[0036] Furthermore, as Figure 3 shown, the outer rod connecting hole 6 can be sleeved on the outer joint rod 2, so as to be able to limit the position of the pulling arm bracket 3.

[0037] Referring to Figure 3 , in a specific embodiment of the present utility model, the pulling arm bracket 3 includes a first arm tube and a second arm tube partially inserted into the first arm tube. The length of the inserted part of the second arm tube and the first arm tube is adjustable. An arm bracket fixing twist 7 is connected to the end of the first arm tube. The arm bracket fixing twist 7 fixes the first arm tube and the second arm tube after the positions of the first arm tube and the second arm tube are adjusted.

[0038] Preferably, as Figure 3As shown, the boom fixed torsion 7 can be telescoped to limit the length of the stretched pulling boom 3, so that it will not shake when connected to the outer rod 2 of the joint.

[0039] Refer to Figures 3 to 4 , in a specific embodiment of the present invention, the fixing bolts 8 threadedly connected to the opposite sides of the turnbuckle fastener 4 are installed on one side of the connecting member 1 close to the edge of the template.

[0040] Furthermore, as Figure 3 、 Figure 4 shown, the turnbuckle fastener 4 can rotate on the surface of the fixing bolt 8 to make the fixing bolt 8 close inward, achieving the effect of pulling the connecting member 1.

[0041] Refer to Figures 2 to 4 , in a specific embodiment of the present invention, the turnbuckle fastener 4 is perpendicular to the connecting member 1.

[0042] Furthermore, as Figures 2 to 4 shown, there are two turnbuckle fasteners 4.

[0043] Furthermore, as Figure 4 shown, the flower basket fastener 4 uses a square frame to increase the contact surface and better exert force to rotate it during use.

[0044] Refer to Figure 4 , in a specific embodiment of the present invention, both ends of the connecting member 1 are semicircularly arranged.

[0045] Refer to Figures 2 to 3 , in a specific embodiment of the present invention, the pulling boom 3 is inclined.

[0046] Furthermore, as Figure 2 、 Figure 3 shown, the pulling boom 3 and the outer rod 2 of the joint are connected to each other to make the pulling boom 3 inclined.

[0047] Refer to Figure 1 And Figure 3 , in a specific embodiment of the present invention, the outer rod 2 of the joint is cylindrical and perpendicular to the surface of the template.

[0048] Furthermore, as Figure 1 、 Figure 3 shown, the contact surface of the cylindrical outer rod 2 of the joint is less than that of other shapes, and there are no convex corners to increase friction. It is better connected to the pulling boom 3 through the cylindrical shape, making it more convenient to place the pulling boom 3.

[0049] As Figures 1 to 4As shown below, the installation process of a tightening tool for a portable and rapid improvement of the joint quality of formwork in the present utility model will be described.

[0050] First, install the outer rod 2 of the joint onto the formwork to form a temporary splicing state. Loosen the armrest fixing twist 7 on the pulling armrest 3, and adjust the length and angle of the armrest to adapt to the spacing of different outer rods 2 of the joint. When the outer rod connection holes 6 on the pulling armrest 3 all pass through four adjacent outer rods 2 of the joint, then lock the armrest fixing twist 7. Finally, by adjusting the two turnbuckle fasteners 4, the four pulling armrests 3 are tightened and the force is transmitted to the outer joint outer rod 2. The outer rod 2 of the joint then transmits the force to two adjacent formworks, causing the two formworks to approach each other until they are aligned at the edges, ultimately achieving the effect of tightening the formwork joint. After the tightening is completed, the subsequent reinforcement system installation operation is carried out normally. After the installation of the reinforcement system is completed, the tightening device can be removed step by step and transferred to the assembly of the next formwork.

[0051] The beneficial effects of a tightening tool for a portable and rapid improvement of the joint quality of formwork in the present utility model are as follows:

[0052] 1. After installing the outer rod of the joint onto the wall formwork, it can better apply force to the wall formwork, and use the turnbuckle fastener to pull and join the wall formwork together, making their contact closer, reducing the seepage of slurry from the joint after pouring cement into the wall, reducing the construction risk of the concrete wall, and reducing the labor and economic costs of subsequent repair of the fair-faced wall.

[0053] 2. By twisting and adjusting the turnbuckle fastener to tighten the connecting piece, the pulling armrest pulls the outer rod of the joint. Using the turnbuckle fastener can effectively reduce the dependence on manpower and make the wall move more smoothly without skew.

[0054] 3. The length of the pulling armrest can be adjusted arbitrarily according to the distance of the outer rod of the joint through the telescoping of the pulling armrest, making the pulling armrest better approach the outer rod of the joint, and the pulling armrest can be driven to adjust the direction through the rotating shaft.

[0055] The present utility model has been described in detail with reference to the embodiments in the accompanying drawings. Those of ordinary skill in the art can make various variations of the present utility model according to the above description.
