Description

Technical Field

[0001] The utility model relates to the technical field of fabricated component preparation, in particular to a device for assisting roughening treatment of the surface of a composite plate. Background Art

[0002] Roughening is a necessary process for the surface of composite slabs. After the initial setting of concrete, grooves are usually formed by manually pulling the surface with a special roughening brush. This operation method has a high roughening efficiency, but the depth of the roughening needs to be assisted by the workers' experience and judgment. The angle of the brush during roughening will also affect the depth of roughening. Therefore, many quality problems such as poor roughening effect of composite slabs occur.

[0003] There are also some methods that use large tools to assist in roughening. They have a gantry structure, which is used to span across both sides of the composite slab. A module that can be lowered and moved is set on the beam. A roughening knife is set in the module. The roughening knife is extended into the surface of the initially set concrete by lifting and lowering, and then moves along the roughening direction to achieve roughening. The roughening quality is high, but the equipment is large in size and inconvenient to move, which greatly reduces the roughening efficiency, and there are safety risks during the movement. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a device for assisting the roughening treatment of the surface of a laminated plate, which can ensure the roughening efficiency under the premise of ensuring the roughening quality, and is safe and reliable.

[0005] In order to solve the above-mentioned technical problems, the utility model provides a device for roughening the surface of an auxiliary composite plate, comprising two auxiliary rails arranged in parallel, a sliding beam rod being arranged across the two auxiliary rails, a C-shaped groove being arranged on the top of the auxiliary rail, a limiting groove being arranged on the bottom of the auxiliary rail, two track pulley modules being arranged at the bottom of the sliding beam rod, the two track pulley modules being respectively arranged in the C-shaped grooves of the two auxiliary rails, and a plurality of roughening rods are also arranged on the side of the sliding beam rod.

[0006] Furthermore, connecting beams are provided at both ends of the two auxiliary rails, and a second C-shaped groove is provided on the connecting beam along the length direction. The second C-shaped groove of the connecting beam is connected and fixed to the C-shaped groove of the corresponding auxiliary rail through a first angle code and a first T-bolt assembly.

[0007] Furthermore, a third C-shaped groove is provided on at least one side of the sliding beam, and the third C-shaped groove of the sliding beam is connected and fixed to the top of the track pulley module by a second angle code and a second T-bolt assembly.

[0008] Furthermore, the top of the roughening rod is fixedly arranged at the bottom of the adjusting bolt, the adjusting bolt is threadedly connected to the adjusting sleeve, a fixed bottom plate is arranged on the outer surface of the adjusting sleeve, and the fixed bottom plate is connected and fixed to the third C-shaped groove of the sliding beam by a third T-bolt assembly.

[0009] Furthermore, a spring is sleeved on the adjusting bolt, and the spring is arranged between the adjusting sleeve and the screw head of the adjusting bolt.

[0010] Furthermore, a rotation-stopping protrusion is arranged on the fixed bottom plate, and the rotation-stopping protrusion extends into the third C-shaped groove.

[0011] Furthermore, a hand-tightening portion is provided on the screw head of the adjusting bolt.

[0012] Furthermore, a marking position is provided on the napping rod.

[0013] Beneficial effects of the utility model:

[0014] With the help of at least two truss steel bars protruding from the surface of the composite plate as the basic support, the auxiliary track cooperates with the sliding beam rod to achieve directional movement, and drives the roughening rod to realize effective roughening operation.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 3 As shown, an embodiment of the device for roughening the surface of an auxiliary composite plate of the utility model comprises two parallel auxiliary rails 1, a sliding beam 2 is arranged across the two auxiliary rails, a C-shaped groove 3 is arranged on the top of the auxiliary rail, a limiting groove 4 is arranged at the bottom of the auxiliary rail, two track pulley modules 5 are arranged at the bottom of the sliding beam, and the two track pulley modules are respectively arranged in the C-shaped grooves of the two auxiliary rails, and a plurality of roughening rods 6 are also arranged on the side of the sliding beam.

[0024] The truss steel bars protruding from the surface of the composite plate are a triangular structure in cross section. The webs of the truss steel bars are located on both sides of the upper chord steel bars. Therefore, the track pulley module cannot slide directly on the upper chord steel bars. Therefore, an auxiliary track is placed on the upper chord steel bars to solve the problem of smooth sliding caused by the protruding webs on both sides. Specifically, the limiting groove at the bottom of the auxiliary track is used to cover the webs on both sides from top to bottom, forming a supporting effect in which the limiting groove notch abuts against the two oblique sides of the triangular structure.

[0025] The above-mentioned truss steel bars are all prefabricated structures in the factory with uniform structural dimensions. When preparing the composite slab, the height of multiple truss steel bars is also consistent. Therefore, the height of the two auxiliary rails after erection and placement is basically the same. There is no misalignment problem when the sliding beam is set on the two auxiliary rails. The sliding beam provides a smooth sliding effect through the track pulley module set in the C-shaped groove. The roughening rod can be directly fixed on the sliding beam. While sliding, the roughening rod slides on the concrete surface to form a groove, which is a roughening operation.

[0026] Since the entire structure is composed of beams, the overall weight is small, and it is easy to move, and it is not easy to cause tipping and injuring people. In order to facilitate the transfer, connecting beams 7 are provided at both ends of the two auxiliary rails. A second C-shaped groove 8 is provided on the connecting beam along the length direction. The second C-shaped groove of the connecting beam is connected and fixed to the corresponding C-shaped groove of the auxiliary rail through a first angle code 9 and a first T-bolt assembly. Figure 2As shown, the structure is easy to adjust, and the two auxiliary rails and the two connecting beams can cooperate to form a fixed frame. When used for the first time, one of the auxiliary rails is fixed to the two connecting beams, and the other auxiliary rail is temporarily connected to the two connecting beams but not locked. When the two auxiliary rails are placed on the corresponding truss steel bars, they are locked. When it is necessary to roughen the next composite slab prepared in the same batch, it can be directly transferred and placed without the need for further adjustment (the placement positions of the truss steel bars in the composite slabs of the same batch are basically the same), which effectively improves the roughening efficiency.

[0027] Furthermore, the cooperation of the C-shaped groove, the second C-shaped groove, the first angle code 9 and the first T-shaped bolt assembly can adaptively adjust the size and fix it, and the operation is simple and convenient.

[0028] Since the spacing between the two auxiliary tracks needs to be adjusted, the spacing between the track pulley modules on the sliding beam also needs to change accordingly. Therefore, a third C-shaped groove 10 is provided on at least one side of the sliding beam. The third C-shaped groove of the sliding beam is connected and fixed to the top of the track pulley module by a second angle code 11 and a second T-bolt assembly. By setting the third C-shaped groove, the locking position of the second angle code can be moved arbitrarily, thereby meeting the locking position requirements. Figure 3 shown.

[0029] In order to improve the scope of application, the method of directly fixing the roughening rod on the sliding beam is not convenient for adjusting the position, that is, adjusting the adjacent spacing of the roughening rods and adjusting the depth of the roughening rods inserted into the concrete. Therefore, the top of the roughening rod is fixedly set at the bottom of the adjusting bolt 12, and the adjusting bolt is threadedly connected with the adjusting sleeve 13. A fixed bottom plate 14 is arranged on the outer surface of the adjusting sleeve. The fixed bottom plate is connected and fixed to the third C-shaped groove of the sliding beam by a third T-bolt assembly 15. Figure 4 As shown, the roughening rod can be raised or lowered by rotating the adjustment bolt, that is, during the installation of the auxiliary rail and the sliding beam, the roughening rod is in the rising position. After the installation is completed, the roughening rod is lowered and penetrated into the concrete by rotating the adjustment bolt. When the roughening depth is reached, it can be stopped. The sliding beam is moved at this height. The sliding beam drives the roughening rod that penetrates into the concrete to move, forming a roughening groove. This is the adjustment of the depth of the roughening rod extending into the concrete. When the spacing between the two truss steel bars changes greatly or slightly, the position of the adjacent roughening rod needs to be adjusted. Then, by loosening the third T-bolt assembly, the third T-bolt assembly can be moved in the third C-shaped groove. After moving into place, it can be locked by the third T-bolt assembly. The operation is convenient.

[0030] During the lifting and lowering adjustment process of the roughening rod, the adjusting bolt may have a rotation problem, causing the roughening rod to move, thereby failing to meet the roughening depth requirement. Therefore, a spring 16 is sleeved on the adjusting bolt, and the spring is arranged between the adjusting sleeve and the screw head of the adjusting bolt. Through the deformation force after the spring is compressed, the thread pre-tightening force between the adjusting bolt and the adjusting sleeve is provided to ensure that the adjusted roughening rod does not move. Of course, the spring can also be replaced by a nut.

[0031] For the convenience of adjusting the rotation of the bolt, its screw head is provided with a hand-spinning portion 17, which facilitates direct hand-spinning operation. During the hand-spinning operation, for the convenience of identifying the size of stretching into the concrete, a marking position is provided on the roughening rod, which can be painted with color or can be identified by arranging an impression.

[0032] Based on the above-mentioned method of locking and matching the third T-bolt assembly with the third C-slot, a anti-rotation protrusion can also be set on the fixed base plate, and the anti-rotation protrusion extends into the third C-slot, thereby ensuring the downward direction of the adjustment sleeve and ensuring the accurate insertion position of the roughening rod.

[0033] The above embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
