Detailed Description
The present invention will be further clarified by the following detailed description, which is to be understood as being given by way of illustration only, and not by way of limitation, of the scope of the invention, which, after reading the present invention, is intended to fall within the scope of the appended claims, as modified by those skilled in the art in various equivalent forms.
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
The utility model discloses a concrete embodiment as follows:
example 1:
as shown in the drawings, the present embodiment mainly uses the support structure for a floor formwork support-free early-dismantling system, so the building carrier here is a wall, the connecting member 2 is an angle plate fixed on the wall, the fastening member 3 is a bolt, wherein the rotating part 301 is a screw, the head 303 is a nut, and a clamping part 302 is coaxially arranged between the screw and the nut.
The wall body to be cast is designed according to the floor distance, the embedded part 1 with the internal thread is embedded in a proper position when the wall body is cast, the opening of the embedded part 1 is outward, and the angle plate with a certain thickness is fixed on the wall body through bolts. The angle plate is provided with a threaded hole which is a longitudinal strip-shaped hole, and the diameter of a first hole 201 at the upper end is smaller than that of a second hole 202 at the lower end; the screw is matched with the internal threaded hole and the first hole 201 of the embedded part 1; the locking portion 302 is cylindrical and has a diameter matching the inner diameter of the second bore 202, and the nut is a polygonal cylinder. When the angle plate is installed, the first hole 201 of the angle plate is aligned with the position of the embedded part 1 and attached to a wall body, the bolt is screwed into the nut and attached to the angle plate, an upward force is applied to the angle plate to lift the angle plate, so that the part of the screw rod, which is positioned in the first hole 201 of the angle plate, is relatively dropped into the second hole 202, the bolt is continuously screwed into the clamping part 302 and enters the second hole 202, and at the moment, the nut covers the second hole 202. When the system is implemented, a plurality of groups of supporting structures are arranged as required to bear supporting beams required by the floor formwork support-free early-dismantling system on the angle plates, and the formwork is laid on the supporting beams to be poured with concrete.
When the bolt is firstly screwed out during disassembly, and the nut is rotated to the clamping part 302 to screw out the second hole 202 on the angle plate, the downward pressing force is applied to the angle plate, so that the screw rod falls into the first hole 201 relative to the angle plate, namely, the angle plate is downwards displaced, and the supporting beam arranged on the angle plate is downwards displaced to form a gap with the reinforced concrete floor slab, so that the floor formwork can be easily and nondestructively disassembled.
Example 2:
as shown in the figure, the embodiment 2 only further improves the threaded hole on the connecting piece 2, and only optimizes the structure of the threaded hole under the condition that other structures are not changed. The diameters of the first hole 201 and the second hole 202 are unchanged, the first hole 201 and the second hole 202 at the upper end of the threaded hole are formed in a mode that the central axes of the first hole 201 and the second hole 202 are perpendicular to the ground, and the circle center of the first hole 201 is located on the intersecting chord of the first hole 201 and is higher than the circle center of the second hole 202. The rest is the same as the embodiment 1 and is not repeated.
The foregoing illustrates and describes the principles of the present invention. And the main features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
