Description

Technical Field

[0001] The utility model belongs to the field of building accessories, and specifically relates to a positioning support cushion block. Background Art

[0002] In reinforced concrete exterior wall insulation systems, prefabricated insulation components consisting of steel mesh and insulation boards are commonly used. When pouring concrete on site, it is usually necessary to position the steel mesh and insulation boards through pads (also called positioning support pads).

[0003] For example, Chinese patent document CN220868484U discloses a positioning support pad, which allows workers to quickly and accurately insert the transverse steel wire and the longitudinal steel wire at the cross point into the corresponding reinforcement groove to complete the positioning of the steel mesh and the insulation board. Due to its fast and accurate characteristics, it reduces installation errors and improves installation efficiency.

[0004] However, the cylinder has only one inlet, and concrete can only enter the cylinder from this inlet during on-site construction. If too little concrete is fed into the cylinder, it will cause voids in the cylinder and reduce the strength of the concrete outer wall, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to design a positioning support pad to improve the strength of the concrete outer wall.

[0006] The technical solution of the utility model is specifically as follows:

[0007] A positioning support pad comprises a sleeve and a chassis fixed together, wherein the lower end of the sleeve is fixed on the chassis, and the upper end of the sleeve is provided with a main feed port, and four groups of steel bar structures and four groups of feed holes are evenly arranged in the circumferential direction of the sleeve, and the feed holes are located below the steel bar structures.

[0008] The feeding hole is rectangular as a whole.

[0009] The steel bar structure is L-shaped as a whole, including a vertical groove and a horizontal groove, and the bottom of the vertical groove is a narrow part.

[0010] At least one side wall of the narrow portion is transitioned to the side wall of the vertical groove body through an inclined surface.

[0011] The two side walls of the narrow portion and the side walls of the vertical groove body are transitioned through inclined surfaces.

[0012] The side wall of the sleeve between two adjacent feed holes is a load-bearing wall, which runs through the entire sleeve. Four reinforcing ribs are arranged between the sleeve and the chassis. The reinforcing ribs are right-angled triangles, one side of which is fixed on the load-bearing wall and the other is fixed on the chassis.

[0013] The upper end of the reinforcing rib plate is located above the transverse groove.

[0014] The narrow part of the sleeve is made of plastic.

[0015] The sleeve and chassis are both made of plastic and are integrally injection molded or compression molded.

[0016] The upper end of the vertical groove is in a shape that is wide at the top and narrow at the bottom.

[0017] Compared with the prior art, the technical effect of the utility model is that a feed hole is opened on the side wall of the cylinder, and concrete can enter the cylinder from multiple directions during on-site construction. More material is fed into the cylinder, and no void is caused in the cylinder, thereby improving the strength of the concrete exterior wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 This is a schematic diagram (1) of the utility model.

[0020] Figure 3 This is a schematic diagram (2) of the utility model. DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-2 A positioning support pad comprises a sleeve 20 and a chassis 10 fixed together, wherein the lower end of the sleeve 20 is fixed on the chassis 10, and a main feed port 24 is provided at the upper end thereof.

[0023] like Figure 1-2 Four groups of steel bar structures 21 and four groups of feed holes 22 are evenly arranged in the circumferential direction of the sleeve 20 , and the feed holes 22 are located below the steel bar structures 21 .

[0024] like Figure 1 In order to facilitate feeding, the feeding hole 22 is rectangular as a whole, so that the feeding area is larger without affecting the strength of the load-bearing wall 23 as much as possible.

[0025] like Figure 2 In order to facilitate the fixation with the steel mesh, the steel structure 21 is L-shaped as a whole, including a vertical groove 211 and a horizontal groove 212. The bottom of the vertical groove 211 is a narrow portion 213. When the steel bar enters the vertical groove 211, the narrow portion 213 can lock the steel bar in the vertical groove 211.

[0026] like Figure 2 In order to facilitate the passage of the steel bars through the narrow portion 213 , at least one side wall of the narrow portion 213 and the side wall of the vertical groove 211 body are transitioned through an inclined surface 215 .

[0027] like Figure 3 In order to facilitate the passage of the steel bars through the narrow portion 213 , the two side walls of the narrow portion 213 and the side walls of the vertical groove 211 body are transitioned through an inclined surface 215 .

[0028] like Figure 1 In order to make the sleeve 20 and the chassis 10 more secure, the side wall of the sleeve 20 between two adjacent feed holes 22 is a load-bearing wall 23, and the load-bearing wall 23 runs through the entire sleeve 20. Four reinforcing ribs 30 are provided between the sleeve 20 and the chassis 10. The reinforcing ribs 30 are right-angled triangles, one side of which is fixed on the load-bearing wall 23 and the other is fixed on the chassis 10.

[0029] like Figure 1 In order to make the sleeve 20 and the chassis 10 more secure, the upper end of the reinforcing rib plate 30 is located above the transverse groove 212 .

[0030] like Figure 1 In order to facilitate the passage of the steel bars through the narrow portion 213 , the narrow portion 213 of the sleeve 20 is made of plastic.

[0031] like Figure 1 In order to make the sleeve 20 and the chassis 10 more solid, the sleeve 20 and the chassis 10 are made of plastic material, and are integrally injection molded or molded. This can also save costs. The plastic material is light in weight, strong in impact resistance, and also has an anti-corrosion effect.

[0032] like Figure 2 In order to facilitate the steel bars to enter the vertical groove 211, the upper end 214 of the vertical groove 211 is in a shape of being wide at the top and narrow at the bottom.

[0033] Its working principle is:

[0034] When used, the method comprises the following steps:

[0035] S1. Calculate the number of positioning support pads (hereinafter referred to as pads) required for this application and prepare the pads;

[0036] S2, the sleeve 20 is located on one side of the insulation board, and the pad is close to the cross point of the steel mesh;

[0037] S3, continue to push the pad forward, so that the cross point of the steel mesh enters the main feed port 24, and at the same time, the steel bars in four directions of the cross point of the steel mesh also enter the four vertical grooves 211 respectively;

[0038] S4, continue to push the pad forward, so that the four steel bars pass through their respective narrow portions 213 and reach the transverse groove 212;

[0039] S5, twist the pad to rotate so that the four steel bars all reach the far end of the transverse groove 212 (the end farther from the vertical groove 211);

[0040] S6. At this time, the pad block is fixed together with the insulation board, so that the steel mesh and the insulation board are fixed together;

[0041] S7, concrete pouring begins, and concrete is uniformly fed into the cylinder from five directions, including the main feed port 24 and the four feed holes 22.

[0042] Starting from step S6, it is already the prior art and will not be described in detail in this application.

[0043] Features of this application:

[0044] S1. Four feeding holes are opened on the side wall of the cylinder. When pouring concrete on site, the concrete can enter the cylinder from five directions at the same time. More material is fed into the cylinder, which will not cause voids in the cylinder and improve the strength of the concrete outer wall.

[0045] S2. The steel structure 21 is L-shaped as a whole. If the locked steel bars escape from the steel structure 21, they need to enter the vertical groove 211 from the horizontal groove 212, which is the escape in the horizontal direction. They also need to cross the narrow part 213, which is the escape in the vertical direction. That is to say, the locked steel bars need to go through a complex route to escape from the steel structure 21, which is quite difficult. This ensures the firmness of the steel mesh and the insulation board before concrete pouring.

[0046] S3. The four feed holes have no specific directionality. Any feed hole can be matched with steel bars in any direction, which reduces the alignment difficulty for construction workers and speeds up construction.

[0047] S4. The material hole 22 is rectangular as a whole, so that the feeding area is larger, the feeding speed is faster, and the amount of material reduction is greater without affecting the strength of the load-bearing wall 23 as much as possible, which helps to increase the strength of the concrete exterior wall.

[0048] S5, sleeve 20, chassis 10 are all made of plastics, and are integrally injection molded or compression molded, which can also save processing costs. Plastics are light in weight, highly impact-resistant, and also have anti-corrosion properties.
