Description

Technical Field

[0001] The utility model relates to the technical field of masonry reinforcement, in particular to a green and energy-saving prefabricated board masonry reinforcement structure. Background Art

[0002] Masonry structures and prefabricated panel structures currently generally have the problem of insufficient bearing capacity and durability of various components;

[0003] The lack of durability is mainly reflected in the carbonization depth of the protective layer of the precast slab. The thickness of the protective layer is generally 10mm. When the carbonization reaches 10mm, the bond strength of the precast floor slab will be greatly lost. At the same time, the protective layer of the precast slab cannot be chiseled off and replaced. Chiseling off the protective layer is equivalent to fully or partially releasing the bond strength of the concrete, reducing the bearing capacity of the precast floor slab, which will seriously affect the normal use of the precast floor slab and leave safety hazards for subsequent use.

[0004] Therefore, the existing needs are not met, and we propose a green and energy-saving prefabricated masonry reinforcement structure. Utility Model Content

[0005] The purpose of the utility model is to provide a green and energy-saving prefabricated board masonry reinforcement structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a green and energy-saving prefabricated board masonry reinforcement structure, comprising: a masonry, a prefabricated board body is arranged on both sides of the masonry, an upper plate body is arranged above the prefabricated board body, a pressure plate is arranged below the prefabricated board body, a grouting material layer is arranged between the upper plate body, the pressure plate and the prefabricated board body, and a plurality of hangers are arranged on the outer wall of the upper plate body, and the upper plate body, the prefabricated board body and the pressure plate are combined together by the hangers.

[0007] Preferably, the pressure plate is a trapezoidal structure arranged at intervals, and a groove is opened inside the pressure plate for pouring the grouting material layer.

[0008] Preferably, the pressure plate and the upper plate body are both provided with steel reinforcements for increasing the stress-bearing strength of the plate body, and the steel reinforcements are composed of a plurality of stress-bearing steel bars in two different directions, front and back and left and right.

[0009] Preferably, the upper plate body and the pressure plate are both provided with L-shaped assembly parts at one end close to the masonry, and the upper plate body, the pressure plate and the prefabricated plate body are assembled and installed with the masonry through the L-shaped assembly parts.

[0010] Preferably, a plurality of assembly bolts for combined installation are provided on the outer wall of the L-shaped assembly.

[0011] Preferably, an assembly groove for assembling bolts is provided inside the masonry.

[0012] Preferably, a plurality of anchor bars for combining with the prefabricated plate body are provided inside the upper plate body and the pressure plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model comprises an upper plate body, a precast plate main body and a pressure plate to form an upper, middle and lower structure. The precast plate main body is located in the middle and acts as a superposition. The plate surface is thickened and a grouting material layer is formed by pouring grouting material to improve the bearing capacity and solve the durability problem of carbonization of the plate surface protective layer. The plate bottom is also thickened and supported and reinforced by a pressure plate and hangers. The plate bottom is passed through the precast plate gap and fixed to the upper plate surface of the precast plate to further improve the bearing capacity of the plate body.

[0022] The upper plate body 10, the prefabricated plate body 2, and the pressure plate 4 form an upper, middle, and lower structure. The prefabricated plate body 2 is located in the middle and acts as a superposition. The plate surface is thickened and a grouting material layer 11 is formed by pouring grouting material to improve the bearing capacity and solve the durability problem of carbonization of the plate surface protective layer.

[0024] In addition, adding steel bars and concrete to the slab surface can achieve the effect of increasing the cross-section. The bottom of the slab uses a pressure plate 4 and a hanger 6, and there is no need for a concrete formwork and a full-floor scaffolding support system. The precast slab is located in the middle layer and has not been dismantled. Therefore, there is no problem with the lateral stability of the wall and no lateral support measures are required. The bottom concrete is poured with grouting material and gravity pouring, which can ensure the density of the concrete and the process is simple and mature.

[0025] Please refer to the figure, the pressure plate 4 is a trapezoidal structure arranged at intervals, and a groove is opened inside the pressure plate 4 for pouring the grouting material layer 11.

[0026] The trapezoidal structure can make the pressure plate 4 play a supporting role for the grouting material layer 11 poured inside. In addition, the spaced trapezoidal structure can effectively improve the bearing capacity of the bottom of the long precast panel.

[0027] Please refer to the figure, the pressure plate 4 and the upper plate body 10 are both provided with steel reinforcement members 5 for improving the stress-bearing strength of the plate body, and the steel reinforcement members 5 are composed of a plurality of stress-bearing steel bars in two different directions, front and back, and left and right.

[0028] The steel reinforcement 5 is used to strengthen the force strength of the pressure plate 4 and the upper plate body 10 in the front-back and left-right directions, and effectively improve the stability and firmness of the plate body.

[0029] Please refer to the figure. The upper plate body 10 and the pressure plate 4 are both provided with an L-shaped assembly part 7 at one end close to the masonry 1. The upper plate body 10, the pressure plate 4 and the prefabricated plate main body 2 are assembled and installed with the masonry 1 through the L-shaped assembly part 7. A plurality of assembly bolts 8 for assembled installation are provided on the outer wall of the L-shaped assembly part 7. The interior of the masonry 1 is provided with an assembly groove 9 for the assembly bolts 8 to be assembled.

[0030] The L-shaped assembly part 7 can be a member such as an angle steel, which is used to improve the stability and firmness between the upper plate body 10, the pressure plate 4, the prefabricated plate body 2 and the masonry 1. The L-shaped assembly part 7 is located at the L-shaped corner of the masonry 1, and is passed through the masonry 1 and extended to another L-shaped assembly part 7 through a long rod-type assembly part, such as a screw, a hanger rod and other components, so that the two are combined together to further improve stability and firmness;

[0031] After the L-shaped assembly part 7 is assembled into the assembly groove 9, the interior is filled and sealed by grouting to further improve stability and firmness.

[0032] Please refer to the figure, a plurality of anchor bars 3 for combining with the prefabricated plate body 2 are arranged inside the upper plate body 10 and the pressure plate 4.

[0033] The anchor bars 3 are used to strengthen the connection between the grouting material layer 11 and the prefabricated board body 2, making the building more stable and firm and improving safety.

The plate bottom is also thickened and supported and reinforced by the pressure plate 4 and the hanging bar 6. Through the gap of the prefabricated plate, through the plate bottom, and fixed on the upper plate surface of the prefabricated plate, the bearing capacity of the plate body is further improved;

[0039] The trapezoidal structure can make the pressure plate 4 play a supporting role for the grouting material layer 11 poured inside. In addition, the interval trapezoidal structure can effectively improve the bearing capacity of the bottom of the long volume precast plate.

[0040] The steel reinforcement 5 is used to strengthen the stress strength of the pressure plate 4 and the upper plate body 10 in the front and rear directions and the left and right directions, thereby effectively improving the stability and firmness of the plate body;
