Description
Technical Field
The utility model relates to a building engineering field especially relates to a fossil fragments pretension connecting piece that is used for horizontal keel back-loading.
Background
At present, the connection of horizontal keel and vertical keel in the curtain wall in the market is mainly splicing and welding. Wherein, the concatenation is divided into two kinds again: one is a sub-unit sequential installation mode, namely, a first vertical keel is installed at first, and then a transverse keel and a vertical keel are alternately installed on the side surface of the first vertical keel in sequence until the installation of the whole curtain wall is completed; the other mode is a transverse keel after-loading mode, namely all the vertical keels of the curtain wall are installed according to the set interval size, and then the transverse keels between the adjacent vertical keels are installed. The former mounting method has the disadvantage that once an error occurs after the installation of the curtain wall or other factors need to replace the keel, all the keels after the replacement position need to be disassembled, otherwise the keels cannot be taken out, and accumulated errors easily occur during the sequential installation of the sub-units, which causes the separation size between the finally installed vertical keels to easily generate large deviation, for example, 50 partitions exist in the curtain wall installed from left to right, if the length of each transverse keel is reduced by 3mm, each partition size (the distance between the adjacent vertical keels) is also reduced by 3mm, and the final error accumulation can reach 150 mm. The horizontal keel between the vertical keels is installed again after the whole installation of the vertical keels is completed in the latter installation mode, the keels needing to be replaced only by corresponding dismounting during replacement of any keel are needed, and accumulated errors cannot occur in the installation mode.
However, the existing curtain wall technology of post-installation of the transverse keel is not mature enough, the bolts are pre-installed on the vertical keels, then the transverse keel is mounted on the bolts to form pre-installation, and before the bolts are not completely fastened or glass is not installed, the transverse keel has a loosening phenomenon, so that inconvenience is caused for subsequent installation, and the installation efficiency and the installation precision are influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a simple structure ingenious, can improve the fossil fragments pretension connecting piece that is used for after-loading of cross keel of installation effectiveness and installation accuracy.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a keel pre-tightening connecting piece for post-installation of a transverse keel comprises a pre-tightening bolt and a pre-tightening end plate, wherein the pre-tightening bolt is installed on a vertical keel, the pre-tightening end plate is arranged at a port of the transverse keel, and a pre-tightening part which is clamped with the pre-tightening bolt and can tighten the pre-tightening bolt is arranged on the pre-tightening end plate.
As a further improvement of the above technical solution:
the pre-tightening part comprises two elastic plates bent on the pre-tightening end plate, a bayonet is formed between the two elastic plates, a notch communicated with the bayonet is further formed in the pre-tightening end plate, the bayonet is clamped with the body of the pre-tightening bolt, and the elastic plates tighten the head of the pre-tightening bolt.
The bending direction of the elastic plate faces to the screw head of the pre-tightening bolt.
Compared with the prior art, the utility model has the advantages of:
the utility model discloses a fossil fragments pretension connecting piece for adorning after cross keel, including pretension bolt and pretension end plate, pretension bolt installs on perpendicular fossil fragments, and the pretension end plate sets up the port at cross keel, is equipped with on the pretension end plate with pretension bolt joint and can strain the pretension portion of pretension bolt. During installation, the pre-tightening bolts are pre-installed on the vertical keels, then the pre-tightening end plates of the transverse keels are hung with the pre-tightening bolts, when the cross keels are hung, the pre-tightening parts are deformed by the axial force of the transverse keels, the pre-tightening parts can be smoothly hung with the pre-tightening bolts, after the cross keels are hung, the axial force disappears, and the pre-tightening parts recover to deform and reversely tighten the pre-tightening bolts to form pre-tightening force. Compared with the traditional structure, the transverse keel can form stronger pretightening force by tightening the pretightening bolt through the pretightening part of the pretightening end plate, the transverse keel cannot be loosened before the bolt is not completely fastened or glass is not installed, the structure is simple and ingenious, and the installation efficiency and the installation precision are improved.

Detailed Description
The invention will be described in further detail with reference to the drawings and specific examples.
Fig. 1 to 5 show the utility model discloses an embodiment of a fossil fragments pretension connecting piece for horizontal keel back dress, including pretension bolt 1 and pretension end plate 2, pretension bolt 1 is installed on perpendicular fossil fragments 3, and pretension end plate 2 sets up the port at horizontal keel 4, is equipped with on pretension end plate 2 with 1 joint of pretension bolt and can strain pretension portion 21 of bolt 1. During installation, the pre-tightening bolt 1 is pre-installed on the vertical keel 3, then the pre-tightening end plate 2 of the transverse keel 4 is hung with the pre-tightening bolt 1, when the pre-tightening part 21 is hung, the pre-tightening part 21 is deformed by the axial force of the transverse keel 4, the pre-tightening part 21 can be smoothly hung with the pre-tightening bolt 1, after the transverse keel 4 is hung, the axial force disappears, and the pre-tightening part 21 recovers deformation and reversely tightens the pre-tightening bolt 1 to form pre-tightening force. Compared with the traditional structure, the transverse keel 4 can be tensioned through the pre-tightening part 21 of the pre-tightening end plate 2 to tighten the pre-tightening bolt 1 to form a strong pre-tightening force, the transverse keel 4 cannot be loosened before the bolt is not completely tightened or glass is not installed, the structure is simple and ingenious, and the installation efficiency and the installation precision are improved.
In this embodiment, the pre-tightening portion 21 includes two elastic plates 211 bent on the pre-tightening end plate 2, a bayonet 212 is formed between the two elastic plates 211, a notch 213 communicated with the bayonet 212 is further formed in the pre-tightening end plate 2, the bayonet 212 is clamped with the body of the pre-tightening bolt 1, and the elastic plate 211 tightens the head of the pre-tightening bolt 1. In this structure, during the installation, opening 213 passes through pretension bolt 1, plays certain guide effect, makes bayonet 212 and pretension bolt 1's spiral shell body form the joint, and elastic plate 211 receives the axial force of cross keel 4 earlier and produces deformation to guarantee that elastic plate 211 can extend spiral shell head department, when the axial force disappears, elastic plate 211 resumes to form reverse knot spiral shell head and forms a tension.
In this embodiment, the bending direction of the elastic plate 211 is toward the screw head of the preload bolt 1. The arrangement is such that the elastic plate 211 can form a line contact with the head of the pretensioning bolt 1, thereby ensuring the tightening force.
