Description

Technical Field

[0001] This invention relates to the field of building formwork fixing technology, and in particular to a building construction formwork clamp and its usage method. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it.

[0003] After the building formwork is erected in the designated location, common methods for fixing the formwork include: The first method involves using F-clamps or through-type threaded rods to symmetrically distributed templates, then fixing the rods to the templates with bolts. However, in practice, the F-clamps and threaded rods are rigid components, and their length will exceed the distance between the two templates. This results in protruding parts on the wall surface after installation, increasing the risk of accidents on the construction site. Furthermore, the extensive use of F-clamps and threaded rods also increases the workload during assembly and disassembly. The second method involves using wire to secure the formwork. While this method ensures that there are no long protrusions on the formwork surface, it requires constant adjustment and bending of the wire during binding, which alters the strength at the bends. Furthermore, the recycled wire has little value, resulting in a significant waste of building materials. The third type is rebar tie. Based on the size of the formwork, fixed-length rebar is bent into the corresponding shape and then the rebar is clamped onto the surface of the formwork. However, after the construction is completed, the rebar tie used in the previous construction will become unusable due to changes in the size of the formwork during the next construction, and new rebar ties need to be made. Therefore, we need a new type of building construction formwork clamp. Summary of the Invention

[0004] The purpose of this invention is to provide a building construction formwork clamp and its usage method to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building construction formwork clamp, characterized in that it includes...

It mainly consists of an angle adjustment section that controls the relative angle between the two adjacent support sections and an orientation adjustment section that controls the orientation of the adjustment section. Switching components: used to control the operation of the locking structure, the angle adjustment section, and the orientation adjustment section.

[0006] Preferably, the locking structure includes a locking strip embedded in the sleeve post, and several locking blocks fixed on the sleeve in a linear array. The sleeve post is slidably inserted into the sleeve, and the locking strip is engaged with the several locking blocks. A spring is fixedly connected between the end face of the locking strip inserted into the sleeve post and the sleeve post.

[0007] Preferably, the included angle adjustment part includes a connecting seat detachably connected to the end face of the sleeve. One side of the connecting seat is rotatably connected to a rotating seat facing the adjustment part. The rotating seat has an installation groove, and a connecting block that is inserted into the side of the sleeve is rotatably connected in the installation groove. A first gear is fixedly connected to the hinge of the connecting block and the installation groove. The rotating seat is rotatably connected to two symmetrically distributed first gears that mesh with the first gear.

[0008] Preferably, the corner of the connecting seat is connected to the side of the sleeve by bolt thread, and the side of the connecting seat facing the sleeve is provided with a convex ring for clearance fit between the connecting seat and the sleeve.

[0009] Preferably, the end face of the sleeve is fixedly connected to a connecting frame that is fitted onto the connecting block, and both the connecting block and the connecting frame are provided with positioning holes for threaded pin installation.

[0010] Preferably, two abutments are symmetrically fixedly connected to the connecting block and slide against the surface of the rotating seat. The abutments are used to abut against the edge of the splice of the two templates, and one of the abutments is through the hinge of the connecting block.

[0011] Preferably, the orientation adjustment component includes a second gear fixed to one end of the rotating seat and rotatably connected to the connecting seat, a second gear condition slidably mounted on the connecting seat and meshing with the second gear, a spring rod fixedly connected between the two ends of the back of the second gear condition and the connecting seat, and an annular protrusion embedded in and rotatably connected to the connecting seat at one end edge of the second gear.

[0012] Preferably, the switching component includes a fixed base fixed to a rotating seat and a H-shaped frame fixed to a connecting seat. A fixing member for pushing two first teeth to swing conditionally is sleeved on the fixed base, and a spring connected to the fixing member is also sleeved on the fixed base. A lifting block that inserts into a locking strip is slidably connected to the bottom of the H-shaped frame. A lifting member that penetrates the middle of the H-shaped frame and extends to the top of the H-shaped frame is fixedly connected to the upper surface of the lifting block. A rotating handle is rotatably connected to one side of the lifting member. A spring column is fixedly connected to the upper surface of the rotating handle, and a slider connected to the telescopic end of the spring column is slidably connected inside the rotating handle. A first traction line and a second traction line are fixedly connected to the slider. Both the first and second traction lines are L-shaped. The traction line moves along a shaped path and passes through the rotating handle and the lifting block. One end of the first traction line is connected to the surface of the fixing member, and one end of the second traction line is connected to the center of the back of the second tooth condition.

[0014] A method for using a formwork clamp in building construction involves connecting two adjacent support parts with a hinge to form a clamp. The length of the support parts is adjusted by controlling a switch. The angle between the two adjacent formwork parts is adjusted by controlling the angle adjustment part to unlock the angle adjustment part, thereby adjusting the angle between the two adjacent support parts. Alternatively, the orientation adjustment part can be unlocked to allow the two adjacent support parts to bend.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting slidingly inserted sleeves and bushings, allows for adjustment of the length of the support portion, enabling it to fully conform to template surfaces of different widths. Furthermore, the hinged portion not only connects adjacent support portions but also allows for angle adjustment of the hinged portion itself and the angle between the hinged portion and the support portion, ensuring that several spliced ​​support portions can individually conform to the template surface. By fixing the angle of the hinged portion, the shape of the spliced ​​support portions is fixed, achieving clamping and fixing of the template. Simultaneously, the detachable support and hinged portions, along with their adjustable size and angle, allow the fixture to be reused.

[0016] 2. By setting up a switch, the present invention can centrally control the length of the support part, the angle of the hinge part itself, and the angle between the hinge part and the support part. Centralized control reduces the difficulty of control and makes it easier for personnel to adjust the shape and angle of the fixture. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-9. This invention provides a technical solution: a construction formwork clamp, including... Support section: Used to fit the template surface, mainly composed of sleeve 6 and sleeve 1, and a locking structure is provided between sleeve 6 and sleeve 1. Hinge section: Used to connect two adjacent support sections and located at the joint of two adjacent templates. It mainly consists of an angle adjustment section that controls the relative angle between the two adjacent support sections and an orientation adjustment section that controls the orientation of the adjustment section. Switching components: used to control the operation of the locking structure, the angle adjustment section, and the orientation adjustment section.

[0021] As shown in Figures 1 and 3, the locking structure includes a locking strip 2 embedded in the sleeve 6, and several locking blocks 3 fixed in a linear array on the sleeve 1. The sleeve 6 is slidably inserted into the sleeve 1, and the locking strip 2 is engaged with the several locking blocks 3. A spring 30 is fixedly connected between the end face of the locking strip 2 inserted into the sleeve 6 and the sleeve 6.

[0022] In practical use, this embodiment is as follows: By raising the locking bar 2 to disengage from several locking blocks 3, the locking state between the sleeve 6 and the sleeve 1 is released, and the distance between the two ends of the sleeve 6 and the sleeve 1 can be adjusted so that the two ends of the support part of the clamp are located on both sides of the template. Then, the locking bar 2 is used to re-engage the locking blocks 3, so that the length of the support part can be fixed. That is, in this embodiment, the length of the support part can be adjusted according to the width of the template.

[0023] Example 2: Figure 4 As shown in Figure 6, the included angle adjustment part includes a connecting seat 8 that is detachably connected to the end face of the sleeve 6. A rotating seat 4 is rotatably connected to one side of the connecting seat 8 towards the adjustment part. The rotating seat 4 has an installation groove 26, and a connecting block 5 that is inserted into the side of the sleeve 1 is rotatably connected in the installation groove 26. A first gear 10 is fixedly connected to the hinge of the connecting block 5 and the installation groove 26. The rotating seat 4 is rotatably connected to two symmetrically distributed first gears 12 that mesh with the first gear 10.

[0024] The corner of the connecting seat 8 is connected to the side of the sleeve 6 by bolt thread, and the side of the connecting seat 8 facing the sleeve 6 is provided with a convex ring 28 for clearance fit between the connecting seat 8 and the sleeve 6.

[0025] The end face of the sleeve 1 is fixedly connected to the connecting frame 13 which is fitted onto the connecting block 5, and both the connecting block 5 and the connecting frame 13 are provided with positioning holes 14 for threaded pin installation.

[0026] Two abutments 9 are symmetrically fixedly connected to the connecting block 5 and slide against the surface of the rotating seat 4. The abutments 9 abut against the edge of the splice of the two templates, and one of the abutments 9 is through the hinge of the connecting block 5.

[0027] In practical use, this embodiment is as follows: Two adjacent support parts are inserted into the connecting frame 13 via a connecting block 5, and connected by a threaded pin passing through the positioning hole 14 on the connecting block 5 and the connecting frame 13. The lengths of the two adjacent support parts are adjusted to correspond to the dimensions of the two adjacent templates. Based on the distance between the two adjacent templates, the two first tooth conditions 12 swing towards each other until they disengage from the surface of the first gear 10. This allows the connecting block 5 to drive the abutment 9 and the first gear 10 to rotate relative to the rotating seat 4, thereby causing the other half of the support part inserted with the connecting block 5 to rotate and swing. This ensures that the included angle between the two adjacent support parts is equal to the included angle between the corresponding two adjacent templates, allowing the clamp to fit onto template surfaces with different included angle distributions. Furthermore, after the included angle of the two adjacent support parts is adjusted, the two first tooth conditions 12 swing towards each other until they mesh with the tooth surface of the first gear 10, preventing the first gear 10 and the connecting block 5 from rotating, thus ensuring the angle of the hinge is fixed. This fixes the angle of the two adjacent support parts, and the two support parts respectively fit onto the surfaces of the two adjacent templates, achieving a fixed template angle. Additionally: When the connecting seat 8 is installed on the sleeve 6 using bolts, the protruding ring 28 ensures that there is a certain gap between the connecting seat 8 and the sleeve 6, so as to ensure that the first traction line 22 can pass smoothly.

[0028] Example 3: Figure 4 Figure 5 and Figure 6 As shown: The orientation adjustment component includes a second gear 29 fixed to one end of the rotating seat 4 and rotatably connected to the connecting seat 8, a second tooth condition 15 slidably mounted on the connecting seat 8 and meshing with the second gear 29, and spring rods 11 fixedly connected between the two ends of the back of the second tooth condition 15 and the connecting seat 8. One end edge of the second gear 29 is provided with an annular protrusion embedded in and rotatably connected to the connecting seat 8.

[0029] In practical use, this embodiment is as follows: To achieve further effective support for the template, the second tooth condition 15 is raised to disengage from the second gear 29, and then the second gear 29 is rotated, causing the rotating seat 4 to rotate at a certain angle. This allows two adjacent support parts to fold and rotate, so that several adjacent support parts are concentrated on a template surface in a zigzag shape. Then, the second tooth condition 15 is lowered to re-engage with the second gear 29, thus fixing the several support parts concentrated on the same template surface relatively. In other words, this embodiment can enhance the fixing strength by increasing the contact area and distribution range between the support parts and the template.

[0030] In addition, when the extension length of the support is greater than the width of the template, the angle between the hinge and the support can be adjusted so that the support fits the template surface in a state that is not parallel to the width of the template, while the two ends of the support are located on both sides of the template.

[0031] Example 4: As shown in Figures 1-9, the switch includes a fixed base 27 fixed on the rotating base 4 and a H-shaped frame 7 fixed on the connecting base 8. A fixing member 25 for pushing the two first tooth conditions 12 to swing is fitted on the fixed base 27, and a spring 30 connected to the fixing member 25 is also fitted on the fixed base 27. A lifting block 16 that is inserted into the locking strip 2 is slidably connected to the bottom of the H-shaped frame 7. A lifting member 17 that penetrates the middle of the H-shaped frame 7 and extends to the top of the H-shaped frame 7 is fixedly connected to the upper surface of the lifting block 16. A rotating handle 20 is rotatably connected to one side of the lifting member 17. A spring post 19 is fixedly connected to the upper surface of the rotating handle 20, and a slider 18 that is slidably connected to the telescopic end of the spring post 19 is embedded in the rotating handle 20. A first traction line 22 and a second traction line 23 are fixedly connected to the slider 18. Both the first traction line 22 and the second traction line 23 move in an L-shaped path and pass through the rotating handle 20. At the rotating part and the lifting block 16, one end of the first traction line 22 is connected to the surface of the fixing member 25, and one end of the second traction line 23 is connected to the center of the tooth back of the second tooth condition 15. The side of the H-shaped frame 7 is fixedly connected to both sides of the portion of the first traction line 22 and the second traction line 23 parallel to the rotating handle 20. The limiting plate 24 is provided with a long through groove 31 and a short through groove 32 for limiting the first traction line 22 and the second traction line 23, and the long through groove 31 and the short through groove 32 on the two limiting plates 24 are staggered.

[0032] The rotating seat 4 has an L-shaped wire hole 21 on its axial surface. The center line of one side of the wire hole 21 coincides with the center line of the rotating seat 4. One end of the first traction wire 22 passes through the gap between the H-shaped frame 7, the connecting seat 8 and the sleeve 6, the wire hole 21, the fixing seat 27, and is perpendicular to the fixing member 25.

[0033] The purpose of this embodiment is to control the normal operation of Embodiment 1, Embodiment 2, and Embodiment 3: Specifically, In the first control embodiment: when the person pulls the rotating handle 20 to move away from the sleeve 6, the rotating handle 20 drives the lifting component 17, the lifting block 16, and the locking bar 2 to rise until they are disengaged from the locking block 3, thereby unlocking the sleeve 6 from the sleeve 1. When the locking bar 2 rises, the spring 30 connected to it stretches elastically, so that after the rotating handle 20 is released, the elastic contraction of the spring 30 enables the locking bar 2 to drive the lifting block 16, the lifting component 17, and the rotating handle 20 to reset. Additionally, as the handle 20 moves away from the sleeve post 6, the slider 18 overcomes the elastic support of the spring post 19 and moves towards the H-shaped frame 7 under the traction of the first traction line 22 and the second traction line 23, ensuring that the first traction line 22 and the second traction line 23 do not pull.

[0034] In Control Embodiment 2: While ensuring the relative position of the lifting component 17 and the H-shaped frame 7 remains unchanged, press down on the slider 18 to prevent it from sliding on the rotating handle 20, and simultaneously swing the rotating handle 20 to the right. This causes the first traction wire 22 connected to the slider 18 to enter the short slot 32 of the right limiting plate 24, and the second traction wire 23 to enter the long slot 31 of the right limiting plate 24. The root of the long slot 31 extends to the H-shaped frame 7. Therefore, when the rotating handle 20 swings to the right, the portion of the second traction wire 23 parallel to the rotating handle 20 will rotate around the point where the second traction wire 23 passes through the rotating handle 20, ensuring that the second traction wire 23 is not pulled out. However, because the first traction wire 22 is stuck in the short slot 32, the portion of the first traction wire 22 parallel to the rotating handle 20 will bend at the short slot 32, and as the rotating handle 20 rotates... As it continues to rotate to the right and is pulled and stretched, under the guidance of the thread hole 21 and the fixing seat 27, the fixing part 25 is driven to press the spring 30 on the fixing seat 27 and rise, so that the two first teeth 12 are separated and the meshing connection with the first gear 10 is released. In addition, the gap between the wire hole 21 and the connecting seat 8 and the sleeve 6 ensures that the first traction wire 22 will not get tangled on the rotating seat 4 when the rotating seat 4 rotates. Furthermore, the first traction wire 22 is rotatably connected to the fixing member 25. Therefore, when the rotating seat 4 rotates, the part of the first traction wire 22 that is twisted in the wire hole 21 will be released by rotation, thus ensuring that the part of the first traction wire 22 located on the center line of the rotating seat 4 will not be twisted. In addition, the fixing member 25 is shown in Figure 7. Its upper, middle and lower cross sections are rectangular, trapezoidal and triangular, respectively. Therefore, when the rectangular part is in contact with the first tooth condition 12, it ensures that the two first tooth conditions 12 are in contact. During the upward process of the triangular part, its inclined surface can force the two first tooth conditions 12 to separate.

[0035] In the third control embodiment: while ensuring that the relative positions of the lifting component 17 and the H-shaped frame 7 remain unchanged, press down on the slider 18 to prevent it from sliding on the rotating handle 20, and simultaneously swing the rotating handle 20 to the left. This causes the first traction wire 22 connected to the slider 18 to enter the long through groove 31 of the left limiting plate 24, and the second traction wire 23 to enter the short through groove 32 of the left limiting plate 24. The root of the long through groove 31 extends to the H-shaped frame 7. Therefore, when the rotating handle 20 swings to the left, the portion of the first traction wire 22 parallel to the rotating handle 20 will rotate around the point where the first traction wire 22 passes through the rotating handle 20, ensuring that the first traction wire 22 is not pulled out. However, because the second traction wire 23 is stuck in the short through groove 32, the portion of the second traction wire 23 parallel to the rotating handle 20 will bend at the short through groove 32, and as the rotating handle 20 rotates... As the gear continues to rotate to the left and is stretched, under the limiting action of the lifting block 16, the second gear condition 15 overcomes the elastic force of the spring rod 11 and rises until it separates from the second gear 29. This allows the second gear 29 to drive the rotating seat 4 to rotate, thus enabling two adjacent support parts to be folded and located on the same template surface.

[0036] The usage and working principle of this device are as follows: Select an appropriate number of support parts according to the number of templates to be assembled. Two adjacent support parts are connected by bolts to the connecting seat 8 and the sleeve 6 of one support part. A threaded pin connects the connecting block 5 to the connecting frame 13 on the other support part, thus achieving a hinged connection between the two adjacent support parts. Based on the width of the template, the operator raises and lowers the lifting component 17. The lifting block 16 drives the locking strip 2 to rise until it disengages from the locking block 3. The operator then pulls the sleeve 6 to adjust the length and releases the lifting component 17, forcing the locking strip 2 to elastically reset and re-engage with the locking block 3. Based on the included angle between the two adjacent templates, the operator turns the rotating handle 20 to the right, causing the first traction line 22 to drive the fixing component 25 to rise, forcing the two first gear conditions 12 to separate and disengage from the first gear 10. This allows the connecting block 5 to drive the connected support part to rotate relative to the other support part. Alternatively, the operator swings the rotating handle 20 to the left, forcing the second traction line 23 to pull the second gear condition 15. Ascending to disengage from the second gear 29, the hinged part can rotate relative to the support part, that is, the swing direction of the connecting block 5 can be adjusted, thereby enabling the adjacent two support parts to achieve angle adjustment in another direction.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
