Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a connecting tool for carat tubes. Background Art

[0002] At present, the design of carat tubes is widely used in rainwater and sewage construction. Carat tubes are hot-wound high-density polyethylene (HDPE) winding structure wall tubes. The wall tube is made of high-density polyethylene resin as the main raw material and is made by hot-wound process. The connection between carat tubes adopts socket electric fusion connection. First, insert a certain length into the socket for positioning; after positioning, insert the socket into the socket 2-3cm and preheat for a certain time; after preheating, heat it, and use a relay tool to heat and push the bottom of the socket, and then heat it for a certain time; use a tensioner to tighten it to prevent the gap between the pipe socket and the socket from affecting the welding effect; cool for 15-30 minutes. The tensioner currently used has slow construction efficiency, easy damage to the carat tube, and easy loosening during tensioning.

[0003] Therefore, the known tightening form of the carat tube tensioner has the above-mentioned inconveniences and problems. Utility Model Content

The ends of the semicircular steel plates are circumferentially fixed with screw rods at both ends of a plurality of matching basket bolts to clamp the two semicircular clamps with basket bolts. An elastic pad is provided on the inner side of the semicircular steel plate so as to softly contact the carat tube.

[0008] The carat tube connection tool of the utility model can also be further implemented by adopting the following technical measures.

[0009] The aforementioned carat tube connecting tool, wherein the steel plate is a Q235 material 30 mm thick steel plate.

[0010] In the aforementioned carat tube connecting tool, the clip bolt is a quick clip bolt, one end of which is provided with a U-shaped opening, and the other end is a movable bolt with a fixing seat, so as to fix the carat tube after the quick clip bolt is tightened.

[0011] The aforementioned carat tube connecting tool, wherein the elastic pad is a polyurethane foam board.

[0012] After adopting the above technical solution, the connection tool of the carat tube of the utility model has the following advantages:

[0013] 1. The tool has a simple structure and is easy to make;

[0014] 2. Ensure that the pipe socket is inserted into the socket without damaging the pipe and preventing it from loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below in conjunction with the embodiments and the accompanying drawings. Example

[0019] The utility model discloses a connecting tool for carat tubes, which comprises a Hough clamp.

[0020] Please refer to Figure 1 , Figure 3 The half clamps are two semicircular clamps, which are semicircular steel plates 1. The two ends of the semicircular steel plates are each provided with a connecting seat 5 that matches each other. The connecting seat is provided with a snap bolt 4. The end of the semicircular steel plate is fixed with a plurality of screw rods 3 at both ends of the basket bolts 6 that match each other in the circumferential direction, so that the two semicircular clamps can be clamped with the basket bolts. An elastic pad is provided on the inner side of the semicircular steel plate to softly contact the carat tube. The steel plate is a 30mm thick steel plate made of Q235 material. The snap bolt is a quick snap bolt, one end of which is provided with a U-shaped opening 8, and the other end is a movable bolt with a fixed seat, so that the carat tube 7 can be fixed after the quick snap bolt is tightened. The elastic pad is a polyurethane foam board 2. Example

[0021] The carat pipe connection tool of the utility model needs to be manufactured according to different pipe diameters to achieve a perfect fit during construction. Table 1 is a material list of the connection tool.

[0022] Table 1 Carat tube connection tool material table (taking DN1000 carat tube as an example)

[0023]

[0024] The manufacturing principle of the carat tube connection tool of the utility model is as follows: first, Q235 δ30mm steel plate is used, and according to the outer diameter size of carat tubes of different specifications, a clamp of a group of two semicircles is processed by a machine tool according to the method shown in the figure. The connection of the two semicircular clamps adopts a quick buckle bolt, which is welded to the clamp A, and the quick buckle bolt is tightened and fixed after AB is combined. Then the screw rods at both ends of the basket bolt (8 sets of 16 pieces) are welded to the corresponding positions, and the specifications and quantity of the basket bolts are adjusted according to the diameter of the carat tube. Finally, the elastic filler (polyurethane foam) is placed in the groove to avoid damage to the carat tube during the clamping process.

[0025] The application principle of the connection tool for the carat pipe of the utility model is as follows: during construction, semicircle A is installed on the pipe from one side, and then semicircle B is installed on the pipe from the other side. After closing, it is fixed with a quick buckle bolt to complete the clamp at one end. The clamp at the other end is installed repeatedly, and after completion, it is tightened with a basket bolt, and the pipes on both sides are slowly and evenly contracted to the middle. After the pipes are butt-jointed, electric hot-melt welding can be performed. The present invention ensures that the pipe socket is inserted into the socket without damaging the pipe and is not easy to loosen.

[0026] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
