Description

Technical Field

[0001] This utility model relates to the field of casting formwork clamps, and in particular to a convenient casting formwork clamp. Background Technology

[0002] In building construction, formwork is often used when pouring beams, walls and columns. The traditional way to fix the formwork is by binding it with wire. The disadvantages are that it is labor-intensive and time-consuming, wastes a lot of materials, and often causes the formwork to shift or fall off because it is not tied tightly, which affects the construction quality.

[0003] Currently, template clamps are used to fix templates, but the clamps of existing template clamps have low compressive strength. Workers may be scratched by the protruding screws when passing by, which greatly reduces the safety of using template clamps. To address this, we have designed a convenient casting template clamp. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a user-friendly casting formwork clamp.

[0005] The technical solution of this utility model to achieve the above objectives is a convenient casting formwork clamp, comprising:

[0006] Right-angle clamping frames are set at the four corners of the casting box constructed from the casting template, and bar magnets are evenly distributed on the two inner surfaces of the frame.

[0007] The clamping sleeve is set on the outside of the right-angle clamping frame and connected to the right-angle clamping frame by a short rod. It is a 90° bend.

[0008] The adjusting square box is located on the outside of the casting square box constructed by the casting template. It has bell-shaped reducers installed at both ends. The small end of the bell-shaped reducer is located outside the adjusting square box, and the large end of the bell-shaped reducer is located inside the adjusting square box.

[0009] The rope drum is located on both sides of the center inside the adjusting box. Its two ends of the shaft are connected to the adjusting box through bearings, and a worm gear is installed at one end of the shaft.

[0010] Two wire ropes are wound on a rope drum and extend out of the adjusting box through a bell-shaped reducer. One wire rope is movably inserted into the clamping sleeve of two right-angle clamping frames, and a rotating male end is installed on one end of this wire rope. The other wire rope is movably inserted into the clamping sleeve of two other right-angle clamping frames, and a rotating female end is installed on one end of this wire rope. The rotating female end is threadedly connected to the rotating male end.

[0011] The worm gear is located below one side of the rope drum and is connected to the adjusting box via a bearing. It meshes with the worm wheel, and a bevel gear is installed at one end.

[0012] The drive shaft is located at the center inside the adjustment box and is connected by bearings. One end of the drive shaft extends out of the adjustment box and is equipped with a control handle. A second bevel gear is mounted on the drive shaft, which meshes with a first bevel gear at one end of each of the two worm gears.

[0013] In this invention, when the drive shaft rotates, the two rope drums simultaneously wind up or release the wire rope.

[0014] In this invention, the right-angled clamping frame is magnetically attached to the four corners of the casting box constructed from the casting template by the magnetic force of the bar magnet.

[0015] In this invention, the position of the rope drum corresponds to the larger end of the flared reducer.

[0016] In this invention, a rubber hose is provided inside the clamping sleeve, and the rubber hose is fitted onto the steel wire rope.

[0017] In this invention, the control handle can be quickly attached and detached from the drive shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By rotating the adjustment handle, the two steel wire ropes are wound up. The tightening of the two steel wire ropes clamps the right-angle clamping frame at the four corners of the casting box constructed from the casting template, effectively improving the clamping efficiency of the casting template and ensuring its clamping effect. At the same time, the adjustable length of the steel wire ropes can increase the range of applications of the device to meet the clamping work of casting templates of different sizes.

[0020] 2. The right-angle clamping frame can be made to fit snugly against the casting template, thus ensuring the clamping effect. At the same time, the magnetic attraction of the bar magnet can facilitate the installation of the right-angle clamping frame, making the device more convenient to use.

[0021] 3. By using two steel wire ropes to quickly connect and tighten, the use of tools such as screws can be avoided, thereby reducing the space occupied by the clamps and preventing workers from being scratched or bumped when passing by, effectively ensuring the safety of the template clamps.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution, such as... Figures 1-4 As shown; a convenient casting template clamp includes: a right-angle clamping frame 1, which is set at the four corners of the casting box constructed by the casting template, and bar magnets 11 are set on its two inner surfaces and evenly distributed; a clamping sleeve 2, which is set on the outside of the right-angle clamping frame 1 and connected to the right-angle clamping frame 1 by a short rod 21, and is a 90° bent pipe.

[0030] In this embodiment of the utility model, four right-angled clamping frames 1 are set at the four corners of the casting box constructed from the casting template, which can use clamping force to clamp the building template, so as to ensure the firmness of the casting template clamping.

[0031] In this embodiment of the invention, by using the bar magnet 11, the right-angle clamp 1 can be attracted to the completed casting template by the magnetic force of the magnet, thus making the device more convenient to use.

[0032] In this embodiment of the utility model, by using the clamping sleeve 2, the steel wire rope 5 can pass through it, and by using the tightening of the steel wire rope 5, it can drive the right-angle clamping frame 1 to clamp the casting template, making the clamping more convenient and faster.

[0033] An adjusting square box 3 is located on the outside of the casting square box constructed from the casting template. It has bell-shaped reducers 31 installed at both ends, with the smaller end of the reducers 31 outside the adjusting square box 3 and the larger end inside. A rope drum 4 is located on both sides of the center inside the adjusting square box 3. Its shaft is connected to the adjusting square box 3 via bearings at both ends, and a worm gear 41 is installed at one end of the shaft. Two steel wire ropes 5 are wound on the rope drum 4 and extend out of the adjusting square box 3 through the bell-shaped reducers 31. One of the steel wire ropes 5 is movably inserted into the clamping sleeves 2 of the two right-angle clamping frames 1. One end of this steel wire rope 5... The rotating male head 51 is installed, and another wire rope 5 is movably inserted into the clamping sleeve 2 of the other two right-angle clamping frames 1. One end of this wire rope 5 is equipped with a rotating female head 52, which is threadedly connected to the rotating male head 51. The worm 42 is located below one side of the rope drum 4 and is connected to the adjusting box 3 through a bearing, and meshes with the worm wheel 41. One end of the worm 42 is equipped with a bevel gear 43. The drive shaft 6 is located at the center inside the adjusting box 3 and is connected through a bearing. One end of the drive shaft extends out of the adjusting box 3 and is equipped with a control handle 61. A second bevel gear 62 is installed on the handle, and the second bevel gear 62 meshes with the first bevel gear 43 at one end of the two worms 42.

[0034] In this embodiment of the invention, the bell-mouth reducer 31 is used to enable the wire rope 5 to be wound or released smoothly when the rope drum 4 rotates to do so, thereby reducing the wear of the wire rope 5.

[0035] In this embodiment of the utility model, by utilizing the meshing transmission of the worm gear 41 and the worm 42, the self-locking property of the worm gear transmission mechanism can be used to ensure that the wire rope 5 maintains a stable length after winding or releasing, thereby enabling the wire rope 5 to be stably tightened, so as to ensure the clamping force of the right-angle clamping frame 1 on the casting template.

[0036] In this embodiment of the utility model, the drive shaft 6 utilizes the meshing of bevel gear 2 62 with two bevel gears 1 43 to drive the worm 42 to rotate. In turn, the meshing of the worm 42 and the worm wheel 41 causes the rope drum 4 to rotate, thereby enabling the operator to quickly control the winding and unwinding of the wire rope 5, making the device more convenient to use.

[0037] In this embodiment of the utility model, by using a separate right-angle clamping frame 1 and a steel wire rope 5 to tighten it, it can clamp casting templates of different sizes, effectively improving its applicability.

[0038] In this invention, when the drive shaft 6 rotates, the two rope drums 4 simultaneously wind up or release the wire rope 5, making the operation more convenient and faster for the workers.

[0039] In this invention, the right-angle clamp 1 is magnetically attached to the four corners of the casting box constructed from the casting template by the magnetic force of the bar magnet 11; this facilitates the installation of the right-angle clamp 1 and makes the device more convenient to use.

[0040] In this invention, the position of the rope drum 4 corresponds to the larger end of the bell-shaped reducer 31; the curvature of the bell-shaped reducer 31 makes it easier to wind and unwind the wire rope 5, thereby facilitating the winding and unwinding of the wire rope 5.

[0041] In this invention, a rubber hose 22 is provided inside the clamping sleeve 2, and the rubber hose 22 is fitted onto the wire rope 5; this can reduce the wear of the wire rope 5 and extend its service life.

[0042] In this invention, the control handle 61 can be quickly attached and detached from the drive shaft 6; the control handle 61 can be removed so that it can be attached to other drive shafts 6, which can facilitate the operation of the staff on the one hand, and on the other hand, the removal of the control handle 6 can prevent the staff from accidentally touching it and ensure the stability of the clamping.

[0043] In specific use of this utility model, the workers install the control handle 61 onto the drive shaft 6 according to the dimensions after the casting template is erected. Then, they rotate the control handle 6 to drive the drive shaft 6 to rotate. Then, by meshing the bevel gear 2 62 with the bevel gear 1 43, the worm gear 42 rotates. By meshing the worm gear 42 with the worm wheel 41, the worm wheel 41 drives the rope drum 4 to rotate, thereby causing the rope drum 4 to release the wire rope 5. When the wire rope 5 has been released to a suitable length, the rotation of the control handle 6 is stopped.

[0044] Subsequently, the staff manually placed the right-angle clamps 1 one by one at the four corners of the casting frame constructed by the casting template, and placed them at a suitable height so that the right-angle clamps 1 could be attracted to the casting template by the magnetic force of the bar magnets 11. Then, the staff pulled the two steel wire ropes 5 to connect them. Then, the staff rotated the male head 51 to install the rotating male head 52, thus completing the connection of the two steel wire ropes 5.

[0045] Finally, the worker reverses the control handle 61, causing the rope drum 4 to rotate in the opposite direction and wind up the wire rope 5. As the wire rope 5 is wound up, it is gradually tightened. The tension of the wire rope 5 is used to squeeze the right-angle clamp 1 against the casting template, thereby clamping the casting box after the casting template is erected. When the wire rope 5 is taut, the worker can stop turning the control handle 61, and the installation of the right-angle clamp 1 is completed.

[0046] Once the formwork is clamped using multiple sets of this device, concrete pouring can begin.

[0047] When it is necessary to disassemble this device, the operator installs the control handle 61 onto the drive shaft 6 and rotates the control handle 61 to release the wire rope 5 from the rope drum 4. When the wire rope 5 is slack, stop rotating the control handle 61. Then, the operator removes the rotating male head 51 from the rotating female head 42 manually or with tools, and then removes the right-angle clamp 1 to complete the disassembly of this device.
