Description

Technical Field

[0001] The invention relates to a clamp for a mold, in particular to a clamp on a building beam template. Background Art

[0002] During the casting process, building beams need to be cast through beam formwork. During the beam formwork support process, the formwork needs to be reinforced by clamping it on the side formwork. Wooden squares are generally fixed on the outside of the formwork as the formwork's slats to reinforce the formwork. At the same time, a clamp clamping part is also provided to prevent the clamp from being directly clamped on the side of the formwork.

[0003] Existing clamps generally include a fixed arm and a movable arm. The movable arm is driven to move by an electric wrench so that the fixed arm and the movable arm can clamp both sides of the beam formwork together. When clamping, many groups of clamps are generally set in the length direction of the building beam. Although this clamping method can play a certain role in clamping the side formwork, since the concrete inside the formwork needs to be vibrated during the subsequent pouring process, the clamps at the vibration points, especially, may have insufficient clamping force and even the risk of the clamp falling off. Summary of the Invention

[0022] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1 This embodiment provides a fixture for a building beam template, such as Figure 1-Figure 7As shown, it includes a clamp body 1, and the clamp body 1 includes multiple groups of clamp components 10 that can be clamped on the wooden square 2. In this embodiment, multiple clamp components 10 are interconnected to form a whole. During the installation process, the uniform stability of the installation of multiple groups of clamp components 10 can be maintained, and an integral component is formed, which can enhance the structural stability of the entire clamp, so that it has better and more stable clamping ability for the beam formwork 3. At the same time, the form of the integral component can also effectively improve the installation efficiency of the clamp.

[0024] The clamp assembly 10 includes a clamp bottom wall 101 and a fixed arm 102 and a movable arm 103 arranged on the clamp bottom wall 101, wherein the fixed arm 102 and the movable arm 103 are arranged parallel to each other and both extend vertically upward, and the clamp bottom wall 101 is horizontally arranged along the width direction of the beam template 3; the movable arm 103 includes a sliding seat 104 that can slide on the clamp bottom wall 101 and a movable arm body 105 fixed on the sliding seat 104, and the clamping of the beam template 3 is achieved by the movement of the movable arm 103 relative to the fixed arm 102.

[0025] In this embodiment, in order to achieve the connection between multiple clamp assemblies 10, the clamp body 1 also includes a connecting assembly for connecting multiple groups of clamp assemblies 10 into one. The connecting assembly includes a connecting beam 501 arranged along the length direction of the beam template 3, and the connecting beam 501 is provided with a slide groove 502 arranged along the length direction of the connecting beam 501. It also includes a connecting arm assembly with one end fixedly connected to the slide groove 502 and the other end fixed on the side of the clamp bottom wall 101. The connecting arm assembly is arranged in a one-to-one correspondence with the clamp assembly 10.

[0026] Among them, a fastening assembly is provided between the connecting arm assembly and the slide groove 502, the fastening assembly includes a connecting screw 504 with both ends passing through the slide groove 502, the connecting arm assembly includes two connecting arms 505, and the two connecting arms 505 are respectively installed at the two ends of the connecting screw 504, and both ends of the connecting screw 504 are provided with a fastening nut 503 for tightening the connecting arm 505 against the side of the connecting beam 501.

[0027] The connecting beam 501 is connected to the bottom wall 101 of the clamp via a connecting arm assembly, which is connected to the slide groove 502 via a connecting screw 504 and a fastening screw. This connection mechanism can be used to connect adjacent clamp assemblies 10 to each other to form an integral component. The connection method via the slide groove 502 can also adjust the spacing between adjacent clamp assemblies 10. At the same time, the clamp assemblies 10 on the connecting beam 501 can be easily removed or added. Different numbers of clamp assemblies 10 can be selected according to actual needs to form the integral component, which is very flexible to use.

[0028] In this embodiment, the sliding seat 104 is mounted with an anti-slip assembly capable of being restrained on the wood 2. The anti-slip assembly includes an anti-slip hook 4 that can hook onto the wood 2 from top to bottom. The wood 2 is arranged between the clamp and the beam template 3. The wood 2 comprises a plurality of spaced-apart timbers, the length of which is aligned with the length of the beam template 3. The wood 2 can serve as the slats of the template, playing a role in reinforcing the template. At the same time, it also provides a clamping position for the clamp to prevent the clamp from directly clamping on the side of the template.

[0029] Anti-slip hooks 4 are installed on both sides of the sliding seat 104. The anti-slip hooks 4 include a hook plate 403 that is arranged horizontally and can extend between the upper and lower adjacent wooden squares 2, and a sliding plate 404 that is arranged vertically and slidably connected to the slide rail 401. An L-shaped hook groove 405 is formed between the hook plate 403 and the sliding plate 404. The vertical surface of the L-shaped hook groove 405 is flush with the outer surface of the movable arm body 105, and the horizontal surface of the L-shaped hook groove 405 can be hooked on the upper end surface of the wooden square 2, wherein the lower end surface of the hook plate can be set to a serrated surface that can increase the anti-slip performance.

[0030] The anti-detachment component includes an anti-detachment lifting component, which includes a slide rail 401 fixed on both sides of the sliding seat 104. The upper part of the anti-detachment hook 4 can be hooked on the wooden square 2, and the lower part is slidably connected to the slide rail 401. The anti-detachment lifting component also includes a connecting plate 402 connected between the anti-detachment hooks 4 on both sides of the same sliding seat 104. The two ends of the connecting plate 402 are respectively connected to the anti-detachment hooks 4 on both sides. The anti-detachment hooks 4 on both sides can move up and down synchronously under the action of the connecting plate 402.

[0031] Specifically, a lifting drive mechanism is also provided on the clamp assembly 10 located at both ends of the connecting beam 501. The lifting drive mechanism includes a lifting screw 406 threadedly connected to the middle part of the connecting plate 402. The upper end of the lifting screw 406 passes through the connecting plate 402 and is rotatably connected to the sliding seat 104. The lower end of the lifting screw 406 is provided with a driving knob 407 for driving the connecting plate 402 to move up and down.

[0032] During the adjustment process, two operators are respectively located at the two ends of the beam formwork 3. They drive the knob 407 to rotate the lifting screw 406 on the clamp assembly 10 at both ends of the beam formwork 3. Under the action of the lifting screw 406, the connecting plate 402 rises or falls, thereby driving the anti-detachment hooks 4 on both sides of the sliding seat 104 to rise and fall synchronously. Finally, all the anti-detachment hooks 4 can be stably engaged on the corresponding wooden squares 2 to improve the stability of the clamp clamping on the beam formwork 3, and at the same time avoid the problem of the clamp being detached from the beam formwork 3 due to unstable clamping.

[0033] In this embodiment, the sliding seat 104 is slidably connected to the bottom wall 101 of the fixture in the following manner: The bottom wall 101 of the clamp includes a square sleeve 106 with an opening 114 at the lower end surface and a long screw 107 rotatably connected to the square sleeve 106. A screw mounting seat is provided on the inner wall of the square sleeve 106 and at the end near the fixed arm 102. The long screw 107 is horizontally arranged in the square sleeve 106 and its end is rotatably connected to the screw mounting seat via a bearing. The sliding seat 104 includes an outer shell 108 that is slidably connected to the outer surface of the square sleeve 106 and an inner slider 109 that is connected to the inner wall of the sliding shell and slidably connected to the inner surface of the square sleeve 106. The inner slider 109 extends into the square sleeve 106 from the long hole 114 and is threadedly connected to the long screw 107. A screw hole is provided at the center of the inner slider 109. The long screw 107 passes through the thread and the two threads are engaged. The inner slider 109 includes a slider 1 that is in the square sleeve 106 and slidably engages with the inner wall of the square sleeve 106 and a slider 2 that passes through the long hole 114 and slidably engages with the hole wall of the long hole 114. The width of the slider 2 is smaller than the width of the slider 1, thereby realizing radial limitation of the inner slider 109 in the square sleeve 106.

[0034] When the long screw 107 rotates, it will drive the inner slider 109 to reciprocate along the axial direction of the long screw 107, and then the inner slider 109 will drive the entire sliding seat 104 to make linear reciprocating motion along the square sleeve 106. The movement of the sliding seat 104 will drive the movable arm body 105 to move toward or away from the beam template 3, and then realize the clamping of the fixed arm 102 and the movable arm 103 on the beam template 3.

[0035] In order to realize the rotation of the long screw 107, in this embodiment, a baffle 110 is installed at the end of the square sleeve 106 away from the fixed arm 102, and the end of the long screw 107 is rotatably connected to the baffle 110. The baffle 110 is fixed to the end of the square sleeve 106 by bolts and the outer surface of the baffle 110 is flush with the outer end surface of the square sleeve 106. A through hole 111 is provided in the middle of the baffle 110 coaxially with the long screw 107, and a hexagonal countersunk hole 112 is provided on the end surface of the long screw 107 corresponding to the through hole 111. The hexagonal countersunk hole 112 can be connected to a manual knob 113 or a drive motor.

[0036] The setting of the baffle 110 can facilitate the installation of the long screw 107 in the square sleeve 106, and can also protect the long screw 107. When the long screw 107 needs to be rotated, the long screw 107 can be rotated manually by inserting the manual knob 113 into the hexagonal countersunk hole 112, or the driving motor can be connected to the hexagonal countersunk hole 112 through a plug-in shaft or a coupling to realize the rotation of the long screw 107 by electric means.

[0037] The installation process of this embodiment is as follows: (1) Select an appropriate number of clamp assemblies 10 in advance according to the length and width of the beam template 3, and adjust the spacing between adjacent clamp assemblies 10 to the desired position, and adjust the spacing between the fixed arm 102 and the movable arm 103 in the clamp assembly 10 to a close position; (2) Two operators are located at both ends of the beam template 3 and move the entire fixture onto the beam template 3 so that the bottom wall 101 of the fixture is pressed against the lower end surface of the beam template 3; (3) The operator first moves the movable arm 103 in the clamp assembly 10 at both ends of the beam template 3 relative to the fixed arm 102, and then adjusts the anti-detachment hook 4 in the clamp assembly 10 at both ends to complete the fixation of the clamps at both ends, thereby achieving pre-fixation of the entire clamp on the beam template 3; (4) The staff then adjusts the movable arm 103 and the anti-slip hook 4 in the middle clamp assembly 10 one by one. First, the movable arm 103 is adjusted so that all the clamp assemblies 10 are stably clamped on the beam formwork 3, and the anti-slip hook 4 on the clamp assembly 10 can extend into the upper end surface of the corresponding wooden square 2. Then, the height of the anti-slip hook 4 is adjusted so that the horizontal and vertical surfaces of the L-shaped hook groove 405 of the anti-slip hook 4 can be tightly pressed against the upper end surface and side surface of the corresponding wooden square 2, completing the fixation of the middle clamp assembly 10.

[0038] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0039] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
