Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building tools, and particularly relates to a concrete pouring template fixing structure and an outer template. Background Art
[0002] At present, at construction sites, formwork is usually used to build a concrete casting outer mold, and concrete is poured into the outer mold. After the concrete dries and hardens, the required concrete casting body will be formed. The outer mold construction is completed by carpenters, which is called "formwork" in the industry. In the process of formwork, how to make the formwork tightly connected together to form an outer mold is the top priority.
[0003] In the prior art, for a larger mold (i.e., an outer mold with a clamping member installed), wooden squares are usually installed around it and nailed with iron nails. At this time, the mold and the wooden squares constitute an outer mold for concrete pouring; for a smaller mold, it is locked with the help of clamp bolts and channel steel fasteners. However, the moisture evaporated during the drying process of the concrete and the moisture in the air easily cause the clamp bolts to rust, making it inconvenient to disassemble. In order to facilitate disassembly, a fastener commonly known as "step-by-step tightening" has appeared in the prior art. It has a hook-shaped clamping rod and a movable clamping head. The movable clamping head is movably installed on the hook-shaped clamping rod, and the mold is clamped with the head of the hook-shaped clamping rod. During assembly, the movable clamping head is struck with a hammer until it is clamped. The gap between the hole of the movable clamping head and the clamping rod is very small, and it has a self-locking function. This self-locking function is sufficient to resist the expansion force generated after the template is stressed. Therefore, when the step-by-step tightening is disassembled, it only needs to be struck in the opposite direction with force to loosen the movable clamping head on the hook-shaped clamping rod, making it more convenient to disassemble.
[0004] However, the contact area of the hook-type clamp rod and movable clamp of a single step-by-step tightening device on the mold is relatively small, so the tightening force of a single step-by-step tightening device on the outer mold is very limited. Usually, for a small-sized concrete casting outer mold with a certain span, multiple step-by-step tightening devices are required to tighten it simultaneously on a single side. Utility Model Content

[0023] The utility model also provides an outer mold for pouring concrete, comprising:
[0024] The mold is formed by a plurality of templates, and a cavity for pouring concrete is formed inside the mold;
[0025] The above-mentioned concrete casting template fixing structure has one or more concrete casting template fixing structures installed on the outside of the mold, and the hooks and claws of the concrete casting template fixing structure are respectively located on both sides of the mold, and the hooks and claws cooperate to clamp the mold.
[0026] Compared with the prior art, the utility model has the following beneficial effects:
[0027] (1) The concrete casting template fixing structure provided by the utility model includes a clamping rod and a clamping head, wherein a clamping hook is provided at one end of the clamping rod, and a clamping hole is provided at the clamping head, wherein the clamping rod is inserted into the clamping hole, and the clamping rod and the clamping hole are loosely matched, and a clamping claw is provided on the clamping head, and the clamping claw is used to cooperate with the clamping hook to apply a tightening force on the concrete casting template, and the number of the above-mentioned clamping hooks and / or clamping claws is multiple.

Since there are multiple clamping hooks and / or clamping claws, compared with the step-by-step tightening in the prior art where there is only one clamping hook and one clamping claw, the concrete pouring formwork fixing structure provided by the utility model has a larger contact area with the concrete pouring formwork and a wider force area, which can not only better clamp the formwork, but also because it has more force points for clamping, fewer of the fixing structures can be used on one side of the formwork to firmly clamp the formwork.

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0039] Embodiment 1:
[0040] The concrete pouring template fixing structure provided by the utility model is as follows Figure 1-Figure 4 As shown, it includes a clamping rod 1 and a clamping head 4, wherein:
[0041] The clamping rod 1 is a straight rod, and a clamping hook 3 is provided at one end of the clamping rod 1. The clamping head 4 is provided with a clamping hole 5, and the clamping rod 1 is inserted into the clamping hole 5, and the clamping rod 1 can slide in the clamping hole 5. Specifically, the clamping rod 1 and the clamping hole 5 are clearance-matched, so that in most cases, the clamping head 4 can slide on the clamping rod 1, but when the clamping head 4 is hit by an external force to make the clamping head 4 tilt on the clamping rod 1, the outer wall of the clamping rod 1 is in close contact with the hole wall of the clamping hole 5 of the clamping head 4, and the clamping head 4 is tightly placed on the clamping rod 1 and can no longer slide on the clamping rod 1. A clamping claw 6 is provided on the clamping head 4, and the clamping claw 6 is used to cooperate with the clamping hook 3 to apply a clamping force on the concrete casting template 13. The number of the above-mentioned clamping hook 3 and / or clamping claw 6 is multiple.
[0042] When in use, the clamping rod 1 is placed outside the formwork (enclosed by the template 13) for concrete pouring, so that the hook 3 is hooked on the outer wall of one side, and then the clamping head 4 is moved so that the claw 6 is pressed on the outer wall of the other side of the formwork, and then the clamping head 4 is hit with a hammer to make the clamping head 4 tilt relative to the clamping rod 1, so that the outer wall of the clamping rod 1 and the hole wall of the clamping hole 5 of the clamping head 4 are tightly fitted, thereby clamping. Since there are multiple hooks 3 and / or claws 6, compared with the step-by-step tightening in the prior art where there is only one hook 3 and claw 6, the concrete pouring template fixing structure provided by the utility model has a larger contact area with the concrete pouring template 13 and a wider force area, which can not only better clamp the formwork, but also because it has more force points for tightening, less of the fixing structure can be used on one side of the formwork, and the formwork can be firmly clamped.
[0043] As an implementation mode of this embodiment, in this embodiment, the number of hooks 3 arranged at one end of the clamping rod 1 is multiple, and the number of claws 6 arranged on the clamping head 4 is one. In this case, one claw 6 cooperates with multiple hooks 3 to clamp the concrete pouring mold together.
[0044] As another implementation of this embodiment, in this embodiment, the number of hooks 3 arranged at one end of the clamping rod 1 is one, and the number of claws 6 arranged on the clamping head 4 is multiple. In this case, one hook 3 cooperates with multiple claws 6 to jointly clamp the mold for concrete pouring.
[0045] The best implementation of this embodiment is: the number of the above-mentioned hooks 3 and claws 6 is multiple. Specifically, a mounting rod 2 is provided at one end of the above-mentioned clamping rod 1, and the mounting rod 2 is perpendicular to the above-mentioned clamping rod 1. Multiple hooks 3 are arranged side by side on the above-mentioned mounting rod 2. The above-mentioned clamping head 4 is a straight rod, and multiple claws 6 are arranged side by side on the clamping head 4. Several claws 6 correspond to several hooks 3 one by one. In this way, multiple claws 6 cooperate with multiple hooks 3 to clamp the concrete casting mold together, and the clamping effect is better. For example, the number of the above-mentioned hooks 3 and claws 6 is 2 or 3 or 4 or 5. Of course, the number of the above-mentioned hooks 3 and the number of claws 6 can also be different.
[0046] The hook 3 is an arc rod or a straight rod inclined toward the other end of the rod 1. As long as the hook 3 is inclined toward the other end of the rod 1, the hook 3 can be the same as the existing step-by-step clamp. The claw 6 is the same as the movable clamp of the step-by-step clamp in the prior art, so it will not be described in detail here.
[0047] Optionally, in this embodiment, one end of the clamping rod 1 is welded and fixed to the middle of the mounting rod 2 or the clamping rod 1 and the mounting rod 2 are integrally formed. In short, the clamping rod 1 and the mounting rod 2 form a T-shaped structure, and the clamping hole 5 is opened in the middle of the clamping head 4. In this way, the clamping hooks 3 and the clamping claws 6 are evenly arranged on both sides of the clamping rod 1, so as to better clamp the mold. Of course, one end of the clamping rod 1 can also be fixedly connected to one end of the mounting rod 2, and / or the clamping head 4 is opened at a position near one end of the clamping rod 1.
[0048] The concrete casting formwork fixing structure provided in the present embodiment locks the clamping head 4 on the clamping rod 1 by means of a knocking force toward the side of the hook 3. When disassembly is required, the clamping head 4 is knocked in the opposite direction by using a knocking force away from the side of the hook 3, so that the clamping head 4 can be loosened on the clamping rod 1. In order to facilitate the application of knocking force on the clamping head 4, in the present embodiment, a thickened block 7 for easy knocking is provided in the middle of the above-mentioned clamping head 4. The thickened block 7 and the claw 6 are respectively located on both sides of the above-mentioned clamping head 4. When knocking the clamping head 4, the above-mentioned thickened block 7 can be hit with a hammer. In this way, not only the clamping head 4 is protected from being deformed by knocking, but also it is more convenient for workers to knock.
[0049] An optional implementation of this embodiment is as follows: an anti-loosening component 8 can be detachably installed on the clamping rod 1, and the anti-loosening component 8 cooperates with the clamping head 4 to prevent the clamping head 4 from loosening without reason when clamping on the clamping rod 1. It is easy to understand that the anti-loosening component 8 is an auxiliary locking component installed on the clamping rod 1, which is used to lock the clamping head 4 on the clamping rod 1. Specifically, after the fixed structure provided by the utility model is used to clamp the mold for pouring concrete, the clamping head 4 is locked on the clamping rod 1 by means of the friction between the hole wall of the clamping hole 5 and the outer wall of the clamping rod 1. At this time, the anti-loosening component 8 is installed on the clamping rod 1 and cooperates with the clamping head 4, so that the clamping head 4 is more firmly connected to the clamping rod 1, and then the fixed structure is more firmly clamped on the mold, further preventing the mold from exploding.
[0050] Optionally, the anti-loosening component 8 may be a seat tube clamp sleeved on the clamping rod 1 .
[0051] Preferably, the anti-loosening assembly 8 includes a sleeve 9 and a locking bolt 10, wherein the sleeve 9 is slidably sleeved on the clamp rod 1, the sleeve 9 and the hook 3 are respectively located on both sides of the clamp head 4, a screw hole is opened on the side wall of the sleeve 9, and the locking bolt 10 is screwed into the screw hole. When locking, the locking bolt 10 is in close contact with the outer wall of the clamp rod 1. In this way, when locking, the locking bolt 10 is in close contact with the outer wall of the clamp rod 1, so that the sleeve 9 is locked on the clamp rod 1 by the friction between the locking bolt 10 and the outer wall of the clamp rod 1, and the clamp head 4 is also clamped on the clamp rod 1, and the sleeve 9 is in close contact with the clamp head 4, so that the clamp head 4 is further locked. When the clamp head 4 needs to be disassembled, the locking bolt 10 is first loosened, and then the thickening block 7 is knocked in the opposite direction with a hammer.
[0052] Optionally, the locking bolt 10 in this embodiment is a conventional bolt.
[0053] Optimally, the locking bolt 10 in this embodiment includes a stud section 11 and a force rod 12, wherein:
[0054] The stud section 11 has a first end and a second end. The stud section 11 is screwed into the screw hole. When locked, the first end is in close contact with the outer wall of the clamping rod 1. The force rod 12 is welded or integrally formed at the second end. The force rod 12 is perpendicular to the stud section 11. With the help of the force rod 12, the user can easily drive the stud section 11 to rotate, so as to more conveniently disassemble and assemble the anti-loosening assembly 8.
[0055] Embodiment 2:
[0056] This embodiment provides an outer mold for concrete pouring. Figure 5 As shown, the outer mold includes a mold and a concrete casting template fixing structure provided in an embodiment, wherein:
[0057] The above-mentioned mold is surrounded by a plurality of templates 13, and a cavity for pouring concrete is formed inside the mold. The above-mentioned concrete pouring template fixing structure is used to clamp the above-mentioned mold. Specifically, one or more concrete pouring template fixing structures are installed on the outside of the mold. The hooks 3 and claws 6 of the concrete pouring template fixing structure are respectively located on both sides of the mold, and the hooks 3 and claws 6 cooperate to clamp the mold.
[0058] For example, the above-mentioned concrete casting template fixing structure is respectively installed at the front end, rear end and upper end of the above-mentioned mold, and the hook 3 of the concrete casting template fixing structure is hooked at the left end of the mold, and the claw 6 is hooked at the right end of the mold.
[0059] The outer mold uses fewer fastening parts (that is, the above-mentioned concrete casting template fixing structure) when building, and the fastening parts are also more secure. When pouring concrete in the cavity inside it, it is less likely to cause mold explosion (that is, concrete supports the outer mold).
[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
