Description

Technical Field

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

[0002] Construction formwork clamps are tools used to fix and support building formwork, which can help workers maintain the stability and position of the formwork when pouring concrete. This clamp is usually made of metal and has the characteristics of high strength, corrosion resistance and long service life.

[0003] There are many clamps on the market, such as formwork clamps, beam clamps, column formwork clamps, adjustable clamps, quick clamps, etc., and most of the construction sites on the market currently use only two types of clamps. One is a screw plus wood. When in use, the screw clamps the wood to limit the position, thereby forming a clamp to clamp the formwork; the other is to use an L-shaped clamp, and then slide a vertical plate on the L-shaped clamp, and then use a pin to limit the vertical plate, so that the L-shaped clamp can be changed into a U-shaped clamp, thereby clamping and limiting the formwork on the construction site.

[0004] For example, a Chinese patent (publication number: CN220247612U) discloses a construction template clamp. Compared with the traditional clamps on the market, this patent increases the area of ​​the clamp. However, in the construction site, the function of the clamp is mostly to clamp the frame of the beam and column, and the increase in the clamp area is rarely used in actual use. Secondly, compared with the traditional clamps on the market, this patent only increases the clamp area, and its structure has not changed. This leads to the fact that in the process of collecting and stacking the clamps, due to the L-shaped structure, it is easy to cause the clamps to be loose during the collection process. During the process, it is inconvenient for on-site construction workers to take the L-shaped clamp because the center of gravity is unstable, one end of the L-shaped clamp is heavier than the other end, which makes it difficult for carpenters to take it. In addition, during the stacking process, due to the L-shaped structure, when two L-shaped clamps are combined together, a "mouth"-shaped structure will be left in the middle, which causes the L-shaped clamp to occupy a large area. Moreover, when using a crane to hoist it onto a truck, the L-shaped clamp is prone to slipping during the hoisting process due to the unstable center of gravity, which in turn affects the safety of on-site personnel. Summary of the invention

[0033] By adopting the above technical scheme, the clamps used in the construction site are: one is a threaded rod plus wood, the wood is fitted with the formwork, and then the threaded rod is used to limit the wood, so that the wood can be tightly combined with the formwork, thereby forming a formwork frame, such as a column formwork, a beam formwork and a shear wall formwork, as well as subsequent secondary structures; the second is the L-shaped structure clamp on the market. During use, the wooden boards are combined together with nails. In order to prevent leakage during pouring and avoid damage to the frame, an L-shaped clamp with a steel structure is used. During use, it is directly stuck on the outside of the frame, and then a vertical plate is slid and installed on the L-shaped structure to make it fit together with the wood on the frame, and then the vertical plate is fixed with a pin to complete the assembly operation, so that the L-shaped structure clamp can become U-shaped, thereby realizing the clamping operation; the structure of the device is as follows: it includes a main cavity column 1, the interior of the main cavity column 1 is a cavity structure and both ends are open, and secondly The rear end of the main cavity column 1 is set to a U-shaped structure and a first latch hole 101 is opened at the rear end of the main cavity column 1, and the first latch hole 101 is connected with the internal cavity. Secondly, a cavity column 2 is rotatably installed at the rear end of the main cavity column 1 (wherein the cavity column 2 can rotate 180 degrees), and circular holes 22 are opened on the upper and lower end surfaces of the right end of the cavity column 2, and springs 31 are fixedly installed inside the circular holes 22, and the ends of the two springs 31 that are far away from each other are fixedly installed with latch columns 3. Under the action of the spring 31, the latch column 3 can reset itself, so the latch column 3 can slide inside the circular hole 22. During use, under the action of the spring 31, the end of the latch column 3 away from the spring 31 can be slid and installed to the inside of the first latch hole 101, thereby allowing the cavity column 2 to rotate on the main cavity column 1. Secondly, when the cavity column 2 in use is on the same straight line as the main cavity column 1, pressing the latch column 3 can allow the cavity column 2 to slide into the inside of the main cavity column 1.

[0034] In addition, the cavity column 2 has a cavity slide groove 21 extending from the left end to the inside, and the upper and lower end surfaces of the cavity column 2 are evenly provided with a plurality of second pin holes 23, and the second pin holes 23 are connected with the cavity slide groove 21, and a sub-cavity column 4 is slidably installed inside the cavity slide groove 21, and the left end of the sub-cavity column 4 is located outside the cavity slide groove 21.

[0035] Auxiliary pin holes 41 are provided on the upper and lower surfaces of one end of the auxiliary cavity column 4 located inside the cavity column 2, and an auxiliary spring 51 is fixedly installed inside the auxiliary pin hole 41. The two auxiliary springs 51 are fixedly installed at the ends away from each other with auxiliary pin columns 5, and the ends of the auxiliary pin columns 5 away from each other are located on the outside of the auxiliary pin hole 41. During use, the ends of the auxiliary pin columns 5 away from each other can be slidably inserted into the second pin hole 23, so that the auxiliary cavity column 4 can be combined with the cavity column 2 to form an integral structure, so that the cavity column 2 can rotate synchronously with the auxiliary cavity column 4, and secondly, the auxiliary cavity column 4 can slide at will, thereby changing the overall length of the cavity column 2 and the auxiliary cavity column 4.

[0036] In addition, a U-shaped box groove 7 is fixedly installed on the left side of the main cavity column 1, and a screw rod 71 is rotatably installed inside the U-shaped box groove 7. The front end of the screw rod 71 is located on the outside of the U-shaped box groove 7. A slide 8 is rotatably installed on the circumferential surface of the screw rod 71, and the upper and lower end surfaces of the slide 8 are in contact with the inner wall of the U-shaped box groove 7, so that when the screw rod 71 is rotated, the slide 8 can only perform linear reciprocating motion under the restriction of the inner wall of the U-shaped box groove 7. Secondly, a first cylinder 81 is rotatably installed on the left end of the slide 8, and the first cylinder 81 can rotate 180 degrees, so that the first cylinder 81 can rotate 180 degrees. A cylinder 81 can be in a parallel state with the main cavity column 1 (secondly, the first cylinder 81 can only be rotated when it is rotated manually, and the first cylinder 81 will not rotate at all when it is not rotated manually). The first cylinder 81 has a groove opened from the left end to the inside, and a first internal thread 82 is opened inside the groove. A first threaded column 83 is rotatably installed inside the groove, wherein a first external thread 831 is opened on the outer circumferential surface of the first threaded column 83. Therefore, the first threaded column 83 can be rotatably connected with the first cylinder 81.

[0037] Then, there is a groove on the first threaded column 83, which is opened from the left end to the inside, and a second internal thread 832 is opened inside the groove. A thread head 9 is rotatably installed on the right end of the second cylinder 10, and the thread head 9 is rotatably connected with the second internal thread 832, so that the second cylinder 10 can be rotatably connected with the first threaded column 83. Secondly, the through hole at the left end of the first threaded column 83 can only allow the second cylinder 10 to slide, and will not allow the thread head 9 to rotate and slide out of the first threaded column 83.

[0038] Secondly, a groove is opened from the left end to the inside of the second cylinder 10, and a third internal thread 11 is opened inside the groove. A thread is opened on the outer circumferential surface of the second threaded column 12, so that the second threaded column 12 can be rotatably connected to the second cylinder 10, and then, the left end of the second threaded column 12 is rotatably connected to the limiting hook 13.

[0039] When in use, the cavity column 2 is pulled out from the inside of the main cavity column 1, and then the latch column 3 is slidably installed into the inside of the first latch hole 101 under the action of the spring 31, so that the cavity column 2 can be rotated, so that the cavity column 2 and the main cavity column 1 are in a mutually perpendicular state, and then the auxiliary cavity column 4 is pulled out. During the pulling-out process, the auxiliary pin column 5 can be inserted into the inside of the auxiliary pin hole 41 under the action of the auxiliary spring 51, so that the auxiliary cavity column 4 can be combined with the cavity column 2 to form a main structure; then the first The first cylinder 81 and the main cavity column 1 are in a mutually perpendicular state. The first threaded column 83 is rotated. During the rotation, the second cylinder 10 can be rotated to rotate the second cylinder 10 with the threaded head 9 until the left end of the threaded head 9 can slide out of the first threaded column 83. Then the second cylinder 10 is rotated to make the second cylinder 10 and the first threaded column 83 perpendicular to each other. Then the first threaded column 83 is slowly adjusted, and the second threaded column 12 is rotated to make the second threaded column 12 with the limit hook 13 gradually rotate. Step by step, approach the hook column 6 until the limit hook 13 can be combined with the hook column 6; at this time, a rectangular structure can be formed under the action of the main cavity column 1, the cavity column 2, the auxiliary cavity column 4, the first cylinder 81 and other structures. During use, the formwork template can be limited to the inside of the rectangular structure, thereby rotating the screw 71, allowing the slide 8 to move with the first cylinder 81, so that the first cylinder 81 gradually approaches the cavity column 2, and then the first threaded column 83 and the second threaded column 12 can be rotated so that the two ends of the first cylinder 81 can be in the same straight line, thereby avoiding the first cylinder 81 from being in a tilted state; under the action of the above-mentioned structure, the formwork can be clamped to realize the formwork operation, and then after use, the above-mentioned construction steps are performed in the opposite direction, so that the equipment can be restored, so that the above-mentioned structure can become a horizontal state, and it will not be an L-shaped structure, so that the equipment is convenient for personnel to take during transportation or taking, avoiding the situation where the center of gravity of the equipment is unstable, thereby avoiding the situation where the clamp slips during the lifting process.

[0040] Specifically, Figures 1 to 5 As shown, a U-shaped box groove 7 is fixedly installed on the left side of the main cavity column 1, and a screw rod 71 is rotatably installed inside the U-shaped box groove 7, and the front end of the screw rod 71 is located on the outside of the U-shaped box groove 7; the slide 8 is slidably installed on the circumferential surface of the screw rod 71, and a first internal thread 82 is provided inside the first cylinder 81, and a first external thread 831 is provided on the outer circumferential surface of the first threaded column 83; a second internal thread 832 is provided inside the first threaded column 83, and a thread head 9 is rotatably installed on the right end of the second cylinder 10, and the thread head 9 is rotatably installed on the inside of the first threaded column 83, and a third internal thread 11 is provided inside the second cylinder 10; a hook column 6 is fixedly provided on the front end of the left part of the auxiliary cavity column 4, and the limit hook 13 can be connected with the hook column 6.

[0041] By adopting the above technical solution, there are many structural columns in the construction sites on the market, so that the equipment needs to deal with different structures during use, such as beams, secondary structures, shear walls and other structures. This will cause a single clamp to be unusable, or the clamp angle or smallness cannot achieve the clamping operation. For example, the patent proposed in the above background technology cannot change the size of the structure, but can change the area of ​​the clamp; compared with traditional clamps on the market, the present device can form rectangular structures of different sizes under the action of structures such as the cavity column 2 and the auxiliary cavity column 4, so as to deal with different frame templates. For example, when using, the cavity column 2 and the main cavity column 1 are in a mutually perpendicular state, and the auxiliary cavity column 4 can be combined with the cavity column 2 to form a main structure, and then the first cylinder 81 is rotated, and the first cylinder 81 and the main cavity column 1 are in a mutually perpendicular state, and then the first threaded column 83, the second cylinder 10, the second threaded column 12 and other structures are rotated successively, so that the limit hook 13 and the hook column 6 are combined to form a rectangular structure.

[0042] Then during use, press the secondary pin column 5 to separate the secondary cavity column 4 from the cavity column 2, so that the secondary cavity column 4 can slide, thereby changing the overall length of the cavity column 2 and the secondary cavity column 4, and then rotate the first threaded column 83 to allow the second cylinder 10, the second threaded column 12 and other structures to be parallel to the main cavity column 1, and finally rotate the screw 71, and then let the slide 8 move with the first cylinder 81, and then rotate the second threaded column 12 to keep the first cylinder 81 in a horizontal state, and then with the cooperation of the above structure, rectangular structures of different sizes can be formed to easily cope with different structural templates; compared with traditional clamps on the market, the device forms different rectangular structures with the cooperation of the above structure, so that the equipment is no longer limited to a single frame template, thereby increasing the practicality of the equipment.

[0043] Working principle: First, the cavity column 2 is pulled out from the inside of the main cavity column 1, and then under the action of the spring 31, the pin column 3 can be slidably installed inside the first pin hole 101, so that the cavity column 2 can rotate, so that the cavity column 2 and the main cavity column 1 are in a mutually perpendicular state.

[0044] Then, the secondary cavity column 4 can be combined with the cavity column 2 to form a main structure.

[0045] Rotate the first cylinder 81 so that the first cylinder 81 and the main cavity column 1 are perpendicular to each other, rotate the second cylinder 10 so that the second cylinder 10 rotates with the threaded head 9 until the left end of the threaded head 9 can slide out of the first threaded column 83, and then slowly adjust the first threaded column 83.

[0046] The second threaded column 12 brings the limiting hook 13 gradually closer to the hook column 6 until the limiting hook 13 can be combined with the hook column 6 .

[0047] At this time, a rectangular structure can be formed under the action of the main cavity column 1, the cavity column 2, the auxiliary cavity column 4, the first cylinder 81 and other structures.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
