Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a light and thin prefabricated block.
Background
The traditional masonry structure wall surface mostly adopts stone veneers which are manually excavated and processed, is influenced by heavier stones and irregular stones, has higher stone veneering construction difficulty, lower efficacy and higher labor cost, and causes the comprehensive popularization to be limited. Compared with stone veneering construction, the precast block overcomes the defects of high stone veneering construction difficulty, low efficiency and high labor cost, thereby being gradually popularized. However, the conventional prefabricated block also has large thickness and heavy weight, which affects construction efficiency and material cost.
In addition, the conventional concrete structure pouring mostly adopts template construction, and treatment measures such as cutting and punching of the template, addition of a pull rod, rust removal and the like are usually required in the construction, so that the material is wasted, and the turnover frequency of the template is reduced. For the installation of a large template, hoisting equipment is required to be installed in a matched mode, and equipment investment is increased. After the construction is finished, the template is required to be watched, and the management cost is increased. In view of the construction appearance quality, the concrete structure constructed by the template has appearance defects such as honeycomb burlap, poor flatness, slab staggering, mold burst, corrosion, uneven color and the like, secondary modification is always performed, and the secondary modification cost is increased.
Disclosure of Invention
The invention aims to overcome the defects and provide a thin and light precast block which is thin, light, high in construction efficiency, high in installation precision, low in construction cost and stable in construction quality, and can be used as a construction template of a cast-in-place concrete structure and a structural object veneering.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention relates to a light and thin prefabricated block, which comprises a standard block and a special-shaped block, wherein: the standard block comprises a straight-face block and an anchoring block A, wherein the anchoring block A is vertically positioned on one side of the straight-face block to enable the standard block to be L-shaped, the left side of the straight-face block is provided with a left rabbet A which is arranged in a left-right staggered manner, the left rabbet A is tightly adjacent to the anchoring block, the right side of the straight-face block is provided with a right rabbet A which is arranged in a left-right staggered manner, the bottom of the straight-face block is provided with a lower rabbet A which is arranged in a high-low staggered manner, and the top of the straight-face block is provided with an upper rabbet A which is arranged in a high-low staggered manner;
the special-shaped block comprises an anchoring block B and a corner block, wherein the anchoring block B8 is vertically positioned on one side of the corner block 7, so that the special-shaped block is U-shaped, the left side of the corner block is provided with a left rabbet B which is arranged in a left-right staggered manner, the left rabbet B is adjacent to the anchoring block, the right side of the corner block is provided with a right rabbet B which is arranged in a left-right staggered manner, the bottom of the corner block is provided with a lower rabbet B which is arranged in a high-low staggered manner, and the top of the corner block is provided with an upper rabbet B which is arranged in a high-low staggered manner.
In the light and thin precast block, the anchor block can be triangular or rectangular according to requirements.
Compared with the prior art, the invention has obvious beneficial effects, and the technical scheme can show that: the invention is divided into two types, namely a standard block and a special-shaped block, wherein the standard block is mainly used for embedding a structural object wall surface at a non-corner, and the appearance of the standard block is L-shaped. The special-shaped block is mainly used for wall surface veneering at the corner of a structure, the appearance is U-shaped, the special-shaped block has the main functions of realizing the adjustment of interlacement of the appearance layer of the structure by setting the lengths of the straight face block and the corner block and realizing the installation connection conversion of the standard blocks at the two sides of the corner of the structure.
The anchoring block plays an anchoring role, namely, the straight face block or the corner block is balanced in the installation process, and the straight face block or the corner block is prevented from overturning outwards in the installation process; and secondly, embedding the anchoring block into the structure through the core filling construction of the structure, so that the precast block is connected with the structure core into a whole through the anchoring block. The outer surface of the straight surface block or the corner block is the exposed part of the prefabricated block veneer, namely the wall surface veneer part of the structure, and the outer surface of the straight surface block or the corner block is mainly used for showing the appearance veneer effect of the structure. According to the requirement, rectangular blocks of various specifications and interlaminar distribution shapes can be displayed by adjusting the size.
The inner surface of the straight surface block or the corner block is a part of the prefabricated block which is in direct contact with the main body of the structure, and the prefabricated block and the structure are better connected through arranging a dovetail groove and roughening treatment, so that the prefabricated block and the structure are well integrated.
The invention optimizes the geometric dimension and the structural appearance, and compared with the conventional precast block, the invention reduces the material consumption and the weight on the same veneering area, greatly improves the construction work efficiency and saves the material cost. Meanwhile, the installation accuracy of the prefabricated block is ensured through structural optimization. But also can be used as a permanent template of cast-in-place concrete and is integrated with a structure. Thereby saving the construction cost and ensuring the construction quality. Along with the gradual maturity of standardized construction technique, the prefabricated section of batch production processing will provide comparatively stable appearance quality and efficient prefabrication machining efficiency for the structure wall facing, makes structure wall facing appearance quality stable and good, and the construction is more high-efficient, the cost is lower.
