Special building block for anti-seismic energy-saving reinforced masonry of well-off building and new construction technology

Abstract

The invention discloses a special building block for an anti-seismic energy-saving reinforced masonry of a well-off building and a new construction technology. The special building block is characterized in that tenon-and-mortise location can be achieved at the wall end of a block body, the middles of walls are only provided with half ribs the heights of which are reduced by half, and the inner walls of the two walls are provided with back-draft vertical rib grooves; the block body is additionally provided with an aluminum foil sandwich insulating layer with an air space layer and an aluminum foil outer heat insulation layer, cleaning ports are not formed in the walls, the long vertical ribs can be vertically connected in advance, then the building block is built while horizontal and perpendicular ribs are tied, filling is carried out while the concrete is vibrated, and the whole process is visually constructed; the problem of the reinforced masonry in the existing rule can be fully solved, the cleaning ports are not formed in the wall foot so as not to be required to be blocked, dust can be removed from the seams when falling in a construction process, longitudinal ribs are not required to be inserted from the top of the wall to a dark hole the hole diameter of which is 12cm and the depth of which is 2-3 meters, and the situation that upper and lower rebars are lapped in the cleaning ports after connecting rebars are inserted can be avoided; a condition that a cavity is formed by arching of the blocked concrete due to the deep hole can be avoided, a situation that uniformity and density of the concrete are hardly ensured caused by the factor that a vibrator is hard to insert to the bottom of the deep hole, a new construction method can ensure visual operation and supervision, hidden dangers in construction are eliminated, and the quality of construction is guaranteed.

Description

(1) Technical field: [0001] The invention discloses an anti-seismic energy-saving reinforced masonry special block and a new masonry technology for well-off buildings, belonging to the technical field of small concrete hollow block buildings, and includes a new block type of wall material and a new technology for masonry construction. (two) background technology: [0002] The industry standard of the People's Republic of China JGJ / T14-2011 "Technical Regulations for Concrete Small Hollow Block Buildings" was implemented on April 1, 2012. This is a summary of decades of practice in China's construction industry and reference to foreign advanced standards. The Ministry of Urban and Rural Development organizes the masters and elites of universities and architectural design and research institutes who lead the development direction of construction technology in China's industry to jointly compile and approve the national industry technical standards approved by the ministerial le...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to continuously open the cleaning openings at the foot of all the walls to clean the leaking debris in the holes and the overlapping operation of the vertical insertion bars and the longitudinal steel bars. Seal the hole, and the sealed hole must not leak grout when pouring concrete. The surface of the sealing must be smooth and flat, and the opening should be repaired, which is labor-intensive and time-consuming. clean up, helpless;

[0005] 2. The block type specified by the current regulations, special reinforced blocks with functional joints (notches), need to knock out the notches while building, and the broken pieces knocked down all over the site will affect the cleanliness of the workshop, which is laborious, laborious and helpless ;

[0006] 3. The horizontal steel bar cannot be tied and fixed with the vertical steel bar, and the structural advantages are not exerted, so it is helpless;

[0007] 4. It must be built to a height of about 3M on the top of the wall, and then longitudinal steel bars are inserted in the dark hole with a diameter of 12cm on the top of the wall. Between one skin and one skin of the block, the standard block structure with two walls, three ribs and two holes specified by the regulations, the inner diameter of the hole is the same It is impossible to be completely aligned. Moreover, there are multi-level horizontal reinforcement bars and vertical insertion bars in the hole. It is not easy to insert the longitudinal reinforcement bars to the bottom and overlap with the pre-embedded vertical insertion bars. It is so helpless. ;

[0008] 5. The final pouring of concrete is the key to the quality of the hole. The hole is 3M deep and the hole diameter is 12cm. The bottom of the hole is cleaned and the deep hole is black after the lap is closed. There are vertical steel bars and horizontal steel bars that hinder pouring. The particle size of concrete coarse aggregate is 16mm. It is necessary to ensure smooth pouring and 100% compactness. The frequency vibrating rod is inserted deep into the bottom of the 3M deep hole for compaction. The vertical steel bar occupies the center of the hole. It is a bit blind and helpless to ensure that the bottomless hole is filled with vibrated concrete;

[0009] The national standard reinforced block building is a structure conforming to the scientific concept. The difficulty of construction is determined by the original block structure. When people find that the block has developed into the era of reinforced block, the function of the wall rib has been transformed. Its block structure should naturally be changed accordingly. It has not been changed now, and future generations must also change it. The block type should be improved as soon as possible, and the closed hole of the reinforced block with two walls and three ribs specified in the current regulations is internationally accepted. If it is changed to an open cavity, the above-mentioned obstacles will be swept away, and new construction methods will naturally form, and will not be popularized
