Referring to fig. 1-5, the utility model provides a square and round fastener, include:

the connecting plates 1 comprise a plurality of horizontal sections 11 and connecting sections 12 connected with the horizontal sections 11, and the connecting plates 1 are connected end to form a square frame;

the locking member 2, the locking member 2 is arranged on the horizontal section 11 to lock the two connecting plates 1 which are connected with each other.

In the above embodiment, the connecting plate 1 includes the horizontal segment 11 and the linkage segment 12, and the end to end of connecting plate 1 forms square frame for the template joint that will make the wall post is in square frame, thereby prevents that the template from warping, and then prevents the production of concrete defect in the template. Specifically, the number of the connecting plates 1 may be four, and the horizontal section 11 of one connecting plate 1 is connected with the connecting section 12 of another connecting plate 1, so that the connecting plates are connected end to form a square frame. The horizontal section 11 and the connecting section 12 at the joint are locked by the locking piece 2 to ensure that two adjacent connecting plates 1 are firmly installed. The embodiment has the advantages of convenient manufacture and capability of preventing the deformation of the template and the generation of concrete defects. Certainly, in order to prevent that the square and round fastener direct action from damaging the template, a strip sleeper can be arranged between the template and the square and round fastener, so that the buffer effect is achieved.

Further, the connecting section 12 is formed with a catching groove 121, and the horizontal section 11 is installed in the catching groove 121. Through setting the linkage segment 12 to the draw-in groove 121, can restrict the removal (from top to bottom and a horizontally one direction) of the horizontal segment 11 of installing in linkage segment 12 in three directions, then lock with retaining member 2 in the other one direction of horizontally for horizontal segment 11 can not remove in four directions about from top to bottom, and then ensures that the installation is firm between connecting plate 1 and the connecting plate 1, and is difficult not hard up.

Further, the locking groove 121 is a U-shaped groove, and the connecting section 12 and the horizontal section 11 of the same connecting plate 1 are integrally formed. Specifically, the connecting plate 1 can be formed by bending the tail end of the horizontal section 11, and the U-shaped groove is convenient to manufacture and install.

Further, a jack 122 is arranged in the U-shaped groove, and a plug connector 111 which is matched with the jack 122 is arranged at a position of the horizontal section 11 corresponding to the jack 122; or, a plug connector 111 is arranged in the new U groove, and a jack 122 matched with the plug connector 111 is arranged at the position of the horizontal section 11 corresponding to the plug connector 111. The two connecting plates 1 connected with each other can be further ensured to be tightly installed and not easy to fall off through the matching of the insertion holes 122 and the plug connectors 111. Specifically, the surface of the plug 111 may be a circular arc shape to facilitate the insertion of the plug into the insertion hole 122.

Furthermore, through holes 112 are formed in the horizontal section 11, the locking member 2 is clamped in the through holes 112, the number of the through holes 112 is multiple, and the through holes 112 are arranged at intervals along the length direction of the horizontal section 11; further, the through holes 112 are also distributed along the width direction of the horizontal section 11. Through setting up the joint of through-hole 112 and retaining member 2, the installation is all very convenient with the dismantlement, is favorable to the operator operation. And all set up a plurality of through-holes 112 on the length and the width direction at horizontal segment 11, can adjust the elasticity of square and round fastener and the size of the square frame that the square and round fastener formed according to actual need, can conveniently adjust and be applicable to the wall post of different interface sizes in the certain limit, improved the application scope of square and round fastener, be favorable to reducing spare parts quantity, and then reduce spare parts cost. It should be noted here that a blind hole may also be provided only on the horizontal segment 11, and the locking member 2 and the horizontal segment 11 may also be clamped. However, as dust is more on a construction site, the blind hole is designed to be easy to accumulate dust, the cleaning is difficult, and the subsequent repeated use is influenced, so that the through hole 112 is arranged to be more suitable for the actual production requirement.

Of course, it is also possible to arrange the anti-skid plates 3 on both sides or one side of the connecting sections 12 and the horizontal sections 11, and the anti-skid plates 3 are arranged higher than the sides of the horizontal sections 11 or the connecting sections 12 to prevent the horizontal sections 11 from sliding off the connecting sections 12 connected thereto. As for the height of the antiskid plate 3, it can be set according to the actual requirement, and it is neither too high, which will affect the matching of the connecting section 12 and the horizontal section 11, nor too low, which will not play a good antiskid role. Specifically, the raised length of the antiskid plate 3 may be set to 2cm to 4 cm.

Further, the aperture of the through hole 112 is gradually reduced from the side toward the locker 2 to the side away from the locker 2. The locking member 2 is a trapezoidal plate 20, and the top edge 201 of the trapezoidal plate 20 is clamped in the through hole 112. Set the diameter of through-hole 112 to the form that the opening is big then gradually dwindle, cooperation trapezoidal retaining member 2 that sets up can ensure that retaining member 2 pegs graft firmly, is difficult for dropping.

Further, the through hole 112 is a threaded hole, the locking member 2 is a threaded fastener, and the locking member 2 is detachably connected with the through hole 112. Of course, the through hole 112 can be a threaded hole, and the threaded fastener can be detachably connected with the through hole 112, so that the installation and the disassembly are very convenient. And the mounting strength of the thread structure is high, and the reliability of the square and round fastener can be further improved.

Above only be the utility model discloses an optional embodiment to do not consequently restrict the utility model discloses a patent range, all be in the utility model discloses a technical idea down, utilize the equivalent structure transform of doing of the contents of description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection scope.
