Detailed Description

First, it should be understood by those skilled in the art that the embodiments described herein are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides a cast-in-place node mould's of prefabricated wall body 1 bearing structure, it includes support piece 3. Based on an inventive concept, the supporting part 3 has two design schemes of a U shape and an L shape. The different designs of the support 3 are explained in detail in the two embodiments described below.

Example 1:

referring to fig. 1 to 4, the present embodiment discloses a support structure of a cast-in-place node mold for a prefabricated wall 1, which includes two prefabricated walls 1 connected to each other in an abutting manner and mold plates 2 for forming the cast-in-place node, where the two mold plates 2 are respectively disposed on two sides of the cast-in-place node.

The supporting member 3 is U-shaped, and the supporting member 3 includes two supporting portions 32 and a limiting portion 31. The top of the prefabricated wall body 1 is provided with a preformed hole 11, and the limiting part 31 is welded with an inserting block 33 matched with the preformed hole 11. Two prepared holes 11 are arranged on the prefabricated wall body 1, and two inserting blocks 33 are also arranged. The two prepared holes 11 contribute to more accurately restricting the position and posture of the stopper portion 31. When the insert 33 is inserted into the prepared hole 11, the two supports 32 are respectively located on two opposite sides of the two mold plates 2, and also on the side of the mold plate 2 facing away from the prefabricated wall 1.

The supporting parts 32 are connected with a plurality of jackscrews 4 used for tightly jacking the mould plate 2 on the prefabricated wall body 1. The plurality of jackscrews 4 are equally spaced along the length of the support portion 32. The support 3 is provided with reinforcing ribs 34. The reinforcing rib 34 extends from the support portion 32 to the other support portion 32 via the stopper portion 31, and the reinforcing rib 34 is located on a side surface of the support 3 facing away from the prefabricated wall body 1. The reinforcing ribs 34 can effectively prevent the support member 3 from being deformed. The thickness of the reinforcing rib 34 is greater than the diameter of the terminal pin 4, and the terminal pin 4 penetrates the reinforcing rib 34. The top thread 4 passing through the reinforcing rib 34 can extend the length of the threaded hole on the supporting member 3, and increase the number of thread turns, so that the supporting portion 32 can be relatively thinned, and the weight of the supporting member 3 can be reduced.

A lifting ring is also welded to the top of the limiting portion 31 to facilitate lifting of the support 3 by a lifting device, which lifting ring is not shown in the drawings.

The two supporting pieces 3 are used for tightly supporting different ends of the die plate 2 on different prefabricated wall bodies 1 respectively. When the prefabricated wall body 1 is used, the supporting piece 3 is lifted by the lifting device, the inserting block 33 is inserted into the preformed hole 11 in an aligned mode, and then the jackscrews 4 are screwed to enable the two die plates 2 to clamp the two prefabricated wall bodies 1. Compared with the prior art, the technical scheme provided by the embodiment does not need to manually carry the clamp for fixing the die plate 2 in a half-conveying manner when the die plate 2 is fixed, so that more labor is saved; the operation process of fixing the die plate 2 is simpler and more time-saving; no holes need to be made in the prefabricated wall 1.

Example 2:

the embodiment discloses a support structure of a cast-in-place node mould of a prefabricated wall body 1, which comprises two prefabricated wall bodies 1 in butt joint and a mould plate 2 for cast-in-place node moulding, wherein compared with the embodiment 1, the butt joint end of the two prefabricated wall bodies 1 is provided with a convex part, and the mould plate 2 is provided with only one block. The two bulges are jointed together in an attaching way. The two attached convex parts and the mould plate 2 jointly enclose a cavity of the cast-in-place node. The supporting member 3 is also included in the present embodiment, and the supporting member 3 is different from the embodiment 1 only in that the supporting member 3 has an "L" shape. Because one side of the cast-in-place node is blocked by the two attached convex parts, the supporting piece 3 only needs to tightly press one mould plate 2 on the prefabricated wall body 1, and the supporting piece 3 only needs one supporting part 32.

Although embodiment 2 is not shown in the drawings, the technical solution of embodiment 2 can be easily understood based on the description of embodiment 1. This embodiment has the same technical effects as embodiment 1.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
