Description
Technical Field
The utility model relates to an architectural decoration field specifically is a length arm elastic joint spare.
Background
When the veneer is paved, the veneer needs to be connected with an inner wall or a plate through the keel. The existing connection mode generally adopts a connecting piece to realize connection. Chinese patent document CN202866100U discloses a "triangular keel clip" in 2013, 4/10, that is, the triangular keel clip is shaped like a U, and one side of the open end of the clip has a triangular slot that can be matched with the triangular keel in shape, or both sides of the open end have triangular slots that can be matched with the triangular keel in shape, both sides of the open end are opened with opposite through holes, and the closed end of the clip is provided with or without a through hole. The applicant declares that the triangular keel clamping piece is processed and formed in advance and has higher precision than field manual bending, so that: 1. the construction is time-saving and labor-saving, the efficiency is high, 2, the levelness of the triangular keel can be ensured, and the mounting effect of the suspended ceiling aluminum gusset plate is good; 2. its metal material can thicken to can realize that a fastener has two triangle draw-in grooves and triangle fossil fragments block simultaneously, the bearing capacity is big, stable firm safety. Similar clips are numerous. In practical application, two ends of the traditional clamping piece are directly connected with the base layer (such as a wall) and the veneer, so that vibration transmission paths are consistent, and the finished veneer has poor sound insulation effect. The existing keel has widely adopted a new structure, two ends of the keel are respectively provided with a matching surface which is parallel to each other, the two matching surfaces are connected through a vertical connecting plate on one side, and a limiting plate is respectively extended towards the opposite direction on the other side, so that the cross section of the whole keel is similar to a C shape, and the traditional clamping piece can not be normally matched with the keel for use.
Disclosure of Invention
Based on above problem, the utility model provides a length arm elastic clamping spare can use with the fine cooperation of C font fossil fragments, and has good syllable-dividing effect.
Since the clip is made of a strip material similar to a section, and the main characteristic of the clip is embodied in the shape of the cross section, the following descriptions of the clip and the installation and matching relationship thereof are pointed out for the corresponding cross section shape unless otherwise specified.
In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a long and short arm elastic clamping piece comprises a base with a fixed structure, wherein the width of the base is matched with the matching surface of a C-shaped keel, a short arm is vertically arranged at one end of the base in the width direction, and a limiting structure matched with the size of a limiting plate of the C-shaped keel is arranged on the inner side surface of the short arm; the other end of the base in the width direction is provided with a long arm which is in matched lap joint with the connecting plate of the C-shaped keel.
The elastic clamping piece with the long and short arms, which is designed by the scheme, has a cross section close to a U shape, comprises a base, and is provided with a fixing structure for fixing the clamping piece with a reference plate or a veneer. The fixing structure has various choices, clamping, inserting, hanging and screw connecting and the like, and can be determined by the technical personnel according to the process requirement. The width of the base is matched with the matching surface of the C-shaped keel. One side vertical connection of base has the forearm, and the medial surface design of forearm has limit structure, and this limit structure is used for realizing spacingly with the limiting plate of C font fossil fragments, and concrete structure also can be decided by technical personnel in the field. The other side design of base is connected with the long arm, and the long arm can overlap joint with the connecting plate adaptation of C font fossil fragments. When this joint spare and C font fossil fragments joint, the connecting plate and the long arm overlap joint of C font fossil fragments, the fitting surface of C font fossil fragments receives the spacing of the width of base, and the connecting plate of C font fossil fragments receives the spacing of the medial surface of short arm to be in the same place C font fossil fragments with the firm joint of this joint spare. Through this joint relation of connection, break traditional vibration transmission path, consequently have fine syllable-dividing effect.
Preferably, the long arm is inclined toward the short arm. This design has increased elasticity for the long arm on the one hand, lasts to pressing from both sides the C font fossil fragments transmission clamp force in joint spare, and on the other hand can make the long arm reduce with the contact surface of the connecting plate of C font fossil fragments to further block vibration conduction route under the prerequisite that does not influence the joint effect, promote syllable-dividing effect.
Preferably, the end of the long arm is provided with a clamping guide edge, and the end of the clamping lead edge inclines outwards. The clamping guide edge is used for guiding the insertion action of the keel and the clamping piece so as to improve the assembly efficiency.
Preferably, the end of the short arm is provided with a stopper bent toward the long arm. The stop gear of short arm medial surface is a spacing strip, and this spacing strip is inboard buckling promptly to the long arm side, and the limiting plate to C font fossil fragments that can be fine is spacing, prevents that the accident from deviating from.
Preferably, the end part of the limiting strip is connected with a clamping guide edge, and the end part of the clamping guide edge inclines outwards. Similarly, the end part of the limiting strip is also connected with a clamping guide edge so as to improve the assembly efficiency.
Preferably, an elastic reinforcing groove which is formed by expanding outward is formed between the base and the long arm and between the base and the short arm. The position of the elastic reinforcing groove is a turning part between the base and the long arm and between the base and the short arm. This design makes this joint spare similar bow, has had fine elastic effect, to optimizing the joint effect, improves assembly efficiency, and it is all beneficial to optimize the effect that gives sound insulation.
Preferably, the thickness of the middle part of the base is larger than the thickness of the two sides. The design is a reinforcing structure, and the middle part of the base which is stressed most intensively has higher strength.
To sum up, the beneficial effects of the utility model are that: can be well matched with the C-shaped keel for use and has good sound insulation effect.
