Description
Technical Field
The utility model relates to the technical field of building structure construction equipment, in particular to a concrete template separating device.
Background
After pouring of the frame members of the building main body structure concrete such as beams, columns and the like is completed, the formwork is required to be removed. And the first step in removing the form is to separate the form from the concrete element. At present, a common mode on site is to use a crow bar, and the contact surface of the template and the concrete member is separated by the crow bar through the lever principle, and then the template is removed. However, the crowbar has large labor capacity and is laborious to use, and a worker is required to forcefully pry the template. The template removing efficiency is affected, and certain potential safety hazards are caused by the resilience force of the template during each prying.
Disclosure of utility model
The utility model provides a concrete template separating device which adopts a screw thread driving structure to directly separate templates of concrete members in an extrusion mode, and has the advantages of high template removing efficiency, time saving and labor saving.
The technical scheme of the utility model is as follows: the concrete template separating device comprises a threaded rod, wherein a nut is coaxially and fixedly arranged at one end of the threaded rod, and a locking end part is arranged at the other end of the threaded rod; the threaded rod is sleeved with a separation assembly, the separation assembly is positioned between the nut and the locking end part, and the middle part of the locking end part is rotationally connected with the threaded rod; the separation assembly comprises a U-shaped pushing block and two limiting blocks symmetrically arranged on two sides of the pushing block; a steel seesaw is fixedly arranged in each limiting block; the middle part of advancing the piece has offered the screw hole, advance the piece through its screw hole and threaded rod threaded connection.
Further: the limiting block is internally provided with a sliding groove through which the steel seesaw can pass, the limiting block is further connected with a locking screw in a threaded manner, the tail of the locking screw extends into the sliding groove, and the tail of the locking screw is abutted to the surface of the steel seesaw to lock the steel seesaw in the limiting block.
Further: the end part of the steel seesaw, which is far away from the limiting block, forms a conical tip.
Further: two pressing blocks are connected to the locking end through bolts, and the two pressing blocks and the two steel seesaw heads are in one-to-one correspondence along the rotation axis of the threaded rod.
The beneficial effect of this scheme:
The scheme provides a concrete form separator, has adopted threaded rod rotation and then drive advancing piece along threaded rod reciprocating motion's structural style. Through fixed steel perk in the both sides of propulsion piece, enter into the gap between concrete and the template through the direct mode of extrusion through steel perk to finally accomplish the result of separating the template by the concrete surface. The screw thread mode drive is effective fast to can be connected with the nut on the threaded rod through external equipment such as increase electric drill or electric air cannon, reach labour saving and time saving's purpose, improve the efficiency of removing the form.
Because the steel seesaw is through the cooperation combined action with the locking tip in order to offset the internal force, compare with the crowbar in the prior art, do not need to adopt concrete as the fulcrum, therefore can not cause the damage to the concrete surface, have made further guarantee to the aspect of shaping concrete quality. Of course, the separating device in this scheme is not only suitable for beam column concrete, such as some special-shaped concrete form stripping and the like, but also unsuitable for long length, namely: the length of the screw rod should not be too long, otherwise the cost is high. For the application scenes in most cases, the separation device is easy to manufacture at low cost and is suitable for various types of projects.

Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
As shown in fig. 1, 2, 3 and 4, the present utility model discloses a concrete form separating apparatus including a threaded rod 7 and a separating assembly mounted on the threaded rod 7. As shown in fig. 2: one end of the threaded rod 7 is coaxially welded and fixed with the nut 2, and the other end of the threaded rod 7 is provided with a locking end 8. In particular, in use, the threaded rod 7 and the locking end 8 rotate relative to each other. The end of the threaded rod 7 can thus also be considered to be rotationally connected to the middle of the locking end 8.
The separation assembly comprises a U-shaped pushing block 3 and two limiting blocks 4 symmetrically arranged on two sides of the pushing block 3. And each limiting block 4 is internally and fixedly provided with a steel seesaw 6. The middle part of the pushing block 3 is provided with a threaded hole, and the pushing block 3 is in threaded connection with the threaded rod 7 through the threaded hole. When the threaded rod 7 rotates, the pusher block 3 does not rotate. Thus, the pusher block 3 gradually moves toward the locking end 8 in the axial direction of the threaded rod 7 by the driving force of the threaded rod 7.
In this solution, the steel seesaw 6 adopts a replaceable mounting structure. As shown in fig. 3: a chute through which the steel seesaw 6 can pass is formed in the limiting block 4, and a locking screw 5 is further connected to the limiting block 4 in a threaded manner. The tail of the locking screw 5 extends into the sliding groove, and the tail of the locking screw 5 is abutted against the surface of the steel seesaw 6 to lock the steel seesaw 6 in the limiting block 4. And, the end of steel seesaw 6 that keeps away from stopper 4 forms the toper point. Unlike current commercially available crowbar heads, the current commercially available crowbar heads are generally L-shaped so that the corner points of the L-shaped heads can be used as reverse support points during operation. The steel seesaw 6 in the scheme directly separates the template 1b through the screw driving force, does not need a reverse supporting point, and uses the locking end 8 as a reverse support. Therefore, the concrete element 1a is not indented or dented from the side, and it is more advantageous to protect the concrete element 1a from damage when the form 1b is removed.
The following description is made in terms of specific embodiments to illustrate the principles of the invention: fig. 1 shows a case where the separation device according to the present embodiment is applied to a beam column 1 to remove a form 1 b. As shown in fig. 3, the conical tip of the steel nose 6 is aligned with the cross-sectional gap between the concrete and the form 1b, while the locking end 8 is located on the other side of the concrete and form 1b with respect to the steel nose 6. And, the locking end 8 is pressed against the surface of the concrete member 1a to avoid damage to the concrete surface. Therefore, in the optimal design, two pressing blocks 9 can be connected to the locking end part 8 through bolts, the two pressing blocks 9 and the two steel seesaw heads 6 are in one-to-one correspondence along the rotation axis of the threaded rod 7, and the stress is balanced.
As shown in fig. 4, an electric drill or a gun is used to socket the nut 2 on the threaded rod 7 and drive the threaded rod 7 to rotate. When the threaded rod 7 rotates, the pushing block 3 is driven by the driving force of the threads to gradually approach the locking end 8, and the steel seesaw 6 is forced to gradually press into the gap between the concrete member 1a and the formwork 1b, so that the formwork 1b is separated from the concrete member 1 a. Therefore, it is necessary to coaxially fix the nut 2 at the end of the threaded rod 7, since the labor intensity can be reduced and the efficiency can be improved by being engaged with other power tools. However, this is not the case, and the same effort can be made to screw the nut 2 by a person if conditions do not allow. Of course this is in comparison with the use of a crowbar.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
