Description
Technical Field
The utility model relates to a can follow the bolt that steel sheet one side or culvert pipe inboard were installed and are under construction belongs to special standard technical field.
Background
In some steel plate bolting works, for the reason of equipment or site, construction can be performed only on one side of a steel plate, which requires installation of bolts and fastening from one side of the steel plate, and it is difficult to perform ordinary bolts because they require inside-outside fitting construction. In addition, in the construction of the culvert pipe with the steel corrugated plates, the culvert pipe is externally narrow, personnel cannot enter the culvert pipe, the steel corrugated plates are required to be connected inside the culvert pipe frequently, and the common bolts cannot meet the construction requirements, so that the bolts which can be installed and connected on one side of the steel plates or on the inner side of the culvert pipe are very necessary to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can follow the bolt that steel sheet one side was installed and is under construction is provided, and this kind of bolt can be in steel sheet one side or culvert pipe inboard erection joint, solves the problem that can only carry out erection joint in steel sheet or culvert pipe one side because of equipment or place reason to accelerate the construction progress, improve work efficiency.
The technical scheme for solving the technical problems is as follows:
the utility model provides a can follow steel sheet one side and carry out bolt of construction, the bolt is the U type, and the U type bolt comprises short screw rod, long screw rod and horizontal pole, and the both ends at the horizontal pole are connected respectively to the short screw rod and the long screw rod of U type bolt, and the short screw rod and the long screw rod of U type bolt are in the coplanar, and the both sides of U type bolt are short the screw rod and the lower part of long screw rod is threaded respectively.
The bolt capable of being installed and constructed from one side of the steel plate is characterized in that the front end of the short screw rod of the U-shaped bolt is conical.
The bolt is installed from one side of the steel plate, and the short screw rod and the long screw rod of the U-shaped bolt are parallel.
In the bolt constructed by being installed from the steel plate side, the short screw of the U-shaped bolt has an angle that opens outward.
In the bolt constructed by being installed from one side of the steel plate, the short screw and the long screw of the U-shaped bolt are respectively provided with an opening angle towards the outer side.
The utility model discloses a beneficial effect is:
the utility model discloses a bolt adopts U type structure, and two screws of U type screw rod are different in length, and the connecting steel plate has the diplopore to cooperate during the installation, wears out the short screw rod of U type bolt from a screw of connecting steel plate one side earlier, penetrates from another screw again, returns one side of steel sheet, uses the nut to fasten two screw rods of U type bolt, accomplishes the work of carrying out erection joint on one side of the steel sheet.
The utility model discloses novel structure is simple, convenient operation, can follow steel sheet one side or the inboard bolted connection of accomplishing of culvert pipe, has solved the problem that can not be under construction in steel sheet or culvert pipe both sides because of equipment or place reason for the construction progress has improved work efficiency effectively.

fig. 4 is a schematic view of the completed state of fig. 3.
The figures are labeled as follows: u-shaped bolt 1, short screw rod 2, long screw rod 3, horizontal pole 4, steel sheet 5, screw 6, nut 7.
Detailed Description
The utility model discloses a U type bolt 1.
Fig. 1 shows that the U-bolt 1 is composed of a short screw 2, a long screw 3 and a cross bar 4, respectively. The short screw rod 2 and the long screw rod 3 of the U-shaped bolt 1 are different in length, the short screw rod 2 and the long screw rod 3 are connected to two ends of the cross rod 4 respectively, the short screw rod 2 and the long screw rod 3 are in the same plane, and the lower portions of the short screw rod 2 and the long screw rod 3 are provided with threads respectively. The front end of the short screw rod 2 of the U-shaped bolt 1 is conical, so that the short screw rod 2 can conveniently penetrate into the screw hole 6 of the steel plate 5.
Fig. 1 shows a U-bolt 1 with parallel short 2 and long 3 shafts.
Fig. 2 shows that the short screw 2 and the long screw 3 of another U-shaped bolt 1 have an opening angle towards the outside respectively, or the short screw 2 of the U-shaped bolt 1 has an opening angle towards the outside, which is more convenient for the short screw 2 to penetrate into the screw hole 6 of the steel plate 5, and the user can select according to the actual situation of the steel plate 5.
Fig. 3 and 4 show that the steel plate with double holes must be adopted to cooperate during installation and construction of the utility model. During the installation, wear out from a screw 6 of 5 one sides of connecting steel sheet earlier the short screw 2 of U type bolt 1, penetrate from another screw 6 again, get back to one side of steel sheet 5, use nut 7 to fasten two screw rods of U type bolt 1, accomplish the work of carrying out erection joint in steel sheet 5 one side. The utility model discloses simple structure possesses very strong practicality, can only follow internally mounted's difficult point when can effective steel sheet or culvert pipe connect. The length of two screws of U type bolt 1 can be adjusted according to thick the board, and long screw 3 mainly is when in order to facilitate the installation, holds long screw 3 so that penetrate the screw 6 of steel sheet 5 with short screw 2 in, and 2 ends of short screw have big chamfer, penetrate the slab during the construction of being convenient for.
In this way, 2 bolts are used, so that the shearing resistance is doubled. In addition, when the bolt is pulled, the pressure-bearing area of the plate is greatly increased, and the instability of the whole structure caused by the deformation of the plate around the bolt is avoided.
The utility model discloses an embodiment as follows:
the diameter of the U-shaped bolt 1 is 20 mm;
the length of the short screw 2 is 60 mm;
the length of the long screw 3 is 80-100 mm;
the length of the cross bar 4 is 75 mm.
