Detailed Implementation

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1 As shown, the A-wall railing embedded part tooling of this embodiment includes a base plate 1 with a surface for close contact with the railing embedded part steel plate, side plates 2 are vertically installed on both sides of the upper surface of the base plate 1, and ear plates 3 for detachably connecting the A-wall side mold are vertically installed in the middle of the upper surface of the base plate 1. The ear plates 3 are parallel to the side plates 2, and positioning holes 4 are provided on the base plate 1 for the U-bolts of the railing embedded part to pass through.

[0034] In use, the top end of the U-shaped bolt of the A-wall railing embedded part is passed through the positioning hole 4, and then fixed with a nut. The A-wall railing embedded part tool is fixed on the A-wall side mold by the ear plate 3, so as to fix the A-wall railing embedded part. After using the A-wall railing embedded part tool, the construction of all A-wall railing embedded parts is more efficient, the arrangement is more regular, and the state after embedding is more standardized. The A-wall railing embedded part tool can be reused, and has high economic value.

[0035] In a relatively specific embodiment, the two ends of the inner side of the side plate 2 and the middle part of the two side faces of the ear plate 3 are connected to the upper surface of the bottom plate 1 through the triangular plate 5. By arranging the triangular plate 5, the stability and strength of the A-wall railing embedded part tool as a whole are higher, especially in the operation of separating it from the concrete by knocking when it is removed, the A-wall embedded part tool is less likely to deform, and the service life is improved.

[0036] The ear plate 3 includes a middle part 3.1 which is an open "H" shape with the middle part upward, and a lateral part 3.2 which is vertically extended outward from the top end of the two side faces of the middle part 3.1, and the lateral part 3.2 is used to support the top of the A-wall side mold. When using the A-wall railing embedded part tool, it is directly placed between the two A-wall side molds from top to bottom, so that the lateral part 3.2 supports the top of the A-wall side mold, so that the A-wall railing embedded part tool can be quickly and effectively placed on the A-wall side mold, achieving the purpose of being more convenient to use.

[0037] In a relatively specific embodiment, the ear plate 3 further includes a connecting plate 6 which is vertically arranged at the bottom of the lateral part 3.2 and parallel to the bottom plate 1, and two connecting holes are arranged on the connecting plate 6. When the A-wall railing embedded part tool is fixed to the A-wall side mold by the bolt, the bolt is directly passed through the connecting hole and the hole on the A-wall side mold, and then the nut is screwed.

[0038] As shown in Figure 2 and Figure 3 based on the above embodiment one, in embodiment two, the ear plate 3 further includes:

[0039] screw rod 3.3, one is slidably arranged at the top of each of the two lateral parts 3.2;

[0040] clamping plate 3.4, fixedly connected to the outer side end of the screw rod 3.3, and the inner side of the clamping plate 3.4 is provided with a clamping groove 3.5 which can be sleeved on the outside of the top of the A-wall side mold;

[0041] screw sleeve 3.6, located in the middle part 3.1, and the opposite ends of the two screw rods 3.3 are respectively screwed with the two ends of the screw sleeve 3.6, and the screw sleeve 3.6 can control the relative movement or opposite movement of the two screw rods 3.3.

[0042] By rotating the screw sleeve 3.6, the two clamping plates 3.4 are kept in a maximum distance state, at this time, the distance between the two clamping plates 3.4 is greater than the distance between the two side molds of the A wall. After placing the A wall railing embedded part tool on the A wall side mold, by rotating the screw sleeve 3.6, the two screw rods 3.3 move relatively, and the two clamping plates 3.4 are driven to move relatively by the two screw sleeves 3.6, so that the clamping groove 3.5 is sleeved on the A wall side mold from the outside to the inside, until the screw sleeve 3.6 cannot continue to rotate, at this time, the two clamping plates 3.4 clamp the A wall side mold, so that the A wall railing embedded part tool is stably installed on the side of the A wall.

[0043] In this way, the installation, use and disassembly of the A wall railing embedded part tool are more convenient, and the nut is not easy to lose, which is more convenient to use.

[0044] Further, the inner top wall of the clamping groove 3.5 is a horizontal plane, and the inner top wall of the clamping groove 3.5 is flush with the lower surface of the lateral part 3.2, the inner bottom wall of the clamping groove 3.5 is an inclined surface with the inner side end downward, and the slot width of the clamping groove 3.5 is greater than the thickness of the top of the A wall side mold.

[0045] When the clamping groove 3.5 clamps the A wall side, the cooperation of the upper and lower sides of the clamping groove 3.5 can stably and effectively limit the A wall railing embedded part tool in the height direction. At the same time, by using the inclined state of the inner bottom wall of the clamping groove 3.5, errors can be better avoided, and the use of the A wall railing embedded part tool is more convenient.

[0046] In embodiment two, the screw rod 3.3 comprises:

[0047] a threaded part 3.3.1 for threaded connection with the threaded sleeve, and the length of the threaded part 3.3.1 is greater than the depth of the clamping groove 3.5 sleeved on the A wall side mold;

[0048] a light rod part 3.3.2 fixedly arranged at the outer side end of the threaded part 3.3.1, and the outer diameter of the light rod part 3.3.2 is smaller than the outer diameter of the threaded part 3.3.1;

[0049] The A wall railing embedded part tool also comprises:

[0050] a back plate 7 arranged between the two ends of the side plate 2 and the ear plate 3, and the lower surface and the two side surfaces of the back plate 7 are in contact with the bottom plate 1, the side plate 2 and the ear plate 3 respectively;

[0051] a top sleeve 8 slidably sleeved on the light rod part 3.3.2, the two back plates 7 located on the same side in the width direction are fixedly connected by the top sleeve 8, and after the clamping plate 3.4 is separated from the A wall side mold by the outward displacement of the threaded part 3.3.1, the top sleeve 8 can provide an external top A wall side mold force for the back plate 7.

[0052] When the A wall rail embedded part tool is disassembled, after the clamping block is separated from the side of the A wall, the screw sleeve 3.6 is continuously rotated, so that the threaded part 3.3.1 externally abuts against the sleeve 8, the sleeve 8 applies an outward force to the abutting plate 7, at this time, the abutting plate 7 can externally abut against the A wall side mold, and the demolding operation of the A wall side mold is more convenient. And after the A wall side mold is demolded, the outer side end of the top can be blocked by the clamping block, which can prevent the A wall side mold from falling down and improve the safety after demolding.

[0053] The technical scope of the utility model is not limited to the contents in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical thought of the utility model, and these modifications and changes shall all belong to the scope of the utility model.
