Description
Technical Field
The utility model relates to a dedicated building blocks product group of novel assembled arrangement of reinforcement building blocks masonry wall structure in civil engineering field belongs to building blocks technical field.
Background
The reinforced block masonry wall is a novel structure system which is based on the traditional brick masonry wall process, is prepared by arranging longitudinal and transverse horizontal steel bars through concrete hollow blocks produced by a factory, pouring concrete according to engineering requirements to fill holes, and bearing vertical load and horizontal load of a building.
The main material of the reinforced block masonry structure, namely the concrete small hollow block, is an industrialized product made of hard concrete, has bearing capacity, and can be combined with reinforcing steel bars and hole-filling concrete to form a reinforced block masonry wall to bear force together. The product must provide channels for the steel bars and the concrete to ensure that the steel bars and the concrete can be arranged in the hollow block wall according to the requirement and ensure the horizontal and vertical through, which puts special requirements on the concrete blocks.
The structure form has higher industrialization degree than the common cast-in-place reinforced concrete structure because of adopting industrialized products, however, the process is complicated, the number of products is various (the variety of building blocks is nearly 20), the field construction is always carried out for years, and the various block types bring great difficulty to the use of operators.
The assembled production occupies a certain share in the construction market due to the advantages of high construction speed, low manufacturing cost and easy quality control. Abroad, it is emerging in large-scale restorative construction in countries after the second major war; more applications exist before the 20 th century and the 90 th era in China. At present, the composite material is mainly used for steel structures, wood structures and reinforced concrete structures. In masonry structures, the application is less; the method is applied to the partially assembled construction in the hollow building block at present abroad, and is not applied to a reinforced building block masonry structure house at present.
For the reinforced block masonry structure, the automatic manufacture of the wall pieces is a key factor reflecting the industrialization level, the block types are few, the difficulty of automatic masonry is greatly reduced, the production efficiency is improved, and the block types as few as possible are the requirements of automatic masonry.
Specifically, the requirements of the fabricated reinforced block masonry structure on the block product are as follows:
the modularized products have the appearance sizes of 390mm, 290mm and 190mm as basic sizes, and form staggered masonry after the modular products are combined and laid;
with channels for horizontal reinforcement (and grouted concrete) to pass through;
the block types are reduced as much as possible, so that the industrial production and management of block products are facilitated, and the wall piece building and mechanical automatic building are facilitated;
the high hole alignment rate (more than 90 percent) can be realized to ensure the overall performance of the reinforced block masonry wall (the hole alignment rate refers to the ratio of the projected area of the formed hole channel to the maximum hole channel area of the block after the upper and lower blocks are constructed in a staggered joint mode).
Current state of the art
Reinforced block masonry structures begin from traditional masonry structure buildings, after environmental protection is more and more emphasized, solid clay bricks needing to be fired are forbidden to be used, and concrete small hollow block buildings are widely used as one of the alternative forms. The non-reinforced small hollow block building does not need to be filled with concrete in principle, the requirement on block types is low, the outline size of the non-reinforced small hollow block building meets 390 and 190 modular blocks, the types are various, and fig. 1 shows the appearances of two common blocks, and the difference is mainly whether the end part of each block is provided with a rib with a convex end face. When building the building blocks with the convex ribs, only the convex parts are filled with mortar, and when building the building blocks with the plane end surfaces, the whole end surfaces are required to be filled with the sand.
In the building of the non-reinforced block, the difference of the two block types is not big, but in the reinforced block masonry structure, the small hole cavity formed at the end face of the former can not ensure that the concrete can be filled and vibrated compactly, because the vibrating rod can not enter the space. Thus, in the final wall, this cavity is present to a greater extent, impairing the performance of the whole structure.
In order to realize reinforcement, the building blocks need to be modified, the current practice is to slot on the wall and ribs of the building blocks, and in order to meet the requirements of walls with various shapes, such as a straight line shape, an L shape, a T shape and the like, at least 9 block types are usually needed, which are not less than the block types shown in the following fig. 2.
Because the concrete block can not be cut at will in use, the worker still has inconvenience when operating above 9 block types, if adopt the machine to carry out automatic building, can be because of the efficiency of the many greatly reduced machines of block type kind. At present, the assembly construction of the reinforced block masonry structure is realized, the automatic building of the concrete block wall pieces is called, and the block type improvement based on the premise of process improvement is a great trend.
The current block type meets the requirements of group building, namely, the building blocks with basic sizes of 390mm, 290mm and 190mm meet the construction requirements of the building blocks with large quantity and wide range at present, the block type meets the reinforcement building block masonry building with the construction height not exceeding 60m, and the height is also the application range limited by the masonry structure design specification at present. But the block type of the building block needs to be refined, and firstly, the block type meets the requirement that the hole rate exceeds more than 90 percent based on the requirement of high hole rate; secondly, the block type is reduced as much as possible, so that the block type is convenient for workers to use and machine masonry; thirdly, on the premise of ensuring the performance of the building block, large holes are provided as much as possible, and hole filling and rib penetrating operations are facilitated; fourthly, after the block type is changed, a corresponding reasonable process is carried out to ensure the construction quality.

The concrete hollow block product group special for the assembly type reinforced block masonry wall structure comprises a first block 1, a second block 2, a third block 3 and a fourth block 4; the first building block 1 is a hollow building block which is formed by surrounding walls to be communicated up and down, wherein a groove is formed in the middle of the top of one wall; the second building block 2 is a hollow building block which is formed by surrounding walls on two sides and front and rear ribs to be communicated up and down, the middle positions of the tops of the front and rear ribs are provided with the same grooves, and the heights of parts of the walls on the two sides, which extend out of the ribs in the same direction, are lower than the parts which do not extend out of the walls; the third building block 3 is a hollow building block which is formed by surrounding walls on two sides and front, middle and rear ribs into a through structure, the middle rib divides the building block into two spaces, the middle positions of the tops of the front, middle and rear ribs are provided with the same grooves, and the middle parts of the tops of the walls on two sides of the space where the middle and rear ribs are located are provided with the same grooves; the fourth building block 4 is a hollow building block which is formed by surrounding walls on two sides and front, middle and rear ribs into a through structure, the middle ribs divide the building block into two spaces, and the middle positions of the tops of the front, middle and rear ribs are provided with the same grooves.
The first building block 1 is 190mm long, 190mm wide and 190mm high.
The length of the second building block 2 is 290mm, the width is 190mm, and the height is 190 mm.
The third building block 3 is 390mm long, 190mm wide and 190mm high.
The length of the No. four building block 4 is 390mm, the width is 190mm, and the height is 190 mm.
The wall thickness of the first building block 1, the second building block 2, the third building block 3 and the fourth building block 4 is 28-32 mm.
The block type series comprises 4 kinds of block types, is about to block type quantity to retrench 4 kinds to do not influence its service function. The blocks with the lengths of 390mm, 290mm and 190mm are respectively provided with channels with specified directions and numbers for arranging horizontal steel bars and pouring concrete. The utility model discloses a design based on 190mm wide building block, but the principle method is not limited to this width, is applicable to width such as 240mm and 290mm equally.
The design principle of the special concrete hollow block product group for the assembled reinforced block masonry wall structure is as follows:
the 9 block types shown in fig. 2 are necessary block types for forming wall sheets in various forms, and a simplified method is to integrate the blocks with the same length but different channel numbers and directions:
(1) the 190mm long block, block 1, remains intact and is used at the end of the wall limb so that the channel at one end is dead-ended and there is no need to pass reinforcement.
(2) The three blocks with the length of 290mm are simplified into 1, namely the second block 2, and the block type is not available in the original 9 basic block types. Namely, the two walls of the half block are provided with half-size channels, so that the reinforcing steel bars can be bent towards two directions for use in the T-shaped wall piece. When it is used at a connection post, the channel does not affect the arrangement of the connection post.
(3) The 390mm long third block 3 is provided with four channels which are respectively arranged on two ribs and two walls and can be used at the corner of a T-shaped wall or the corner of an L-shaped wall.
(4)390mm long No. four building blocks 4, with three all link up and set up the channel with the rib, supply reinforcing bar and concrete to pass through, be used for in-line wall limb.
The high pair porosity is to ensure an effective vertical hole area to facilitate vertical rebar placement and concrete placement. Mortar joints with the width (or thickness) of 10mm are arranged between the building blocks, and the building blocks need to be constructed by staggered joints of upper and lower skins (namely, the middle rib of the upper skin building block corresponds to the two side ribs of the lower skin building block, and the two side ribs of the upper skin building block correspond to the middle rib of the lower skin building block), as shown in fig. 7, the width of the middle rib of the building block should be as large as possible as the width of the two side ribs plus the width of the mortar joints, so that the maximum hole aligning rate (theoretically 100%) can be obtained. Because the holes of the building blocks need to have certain taper when the building blocks are demoulded during production, the size of the holes of the mortar spreading surface of the building blocks is slightly smaller than that of the holes of the mortar sitting surface, and the hole aligning rate of the building blocks is not 100 percent actually.
In order to improve the porosity of the building block, the block type is optimized, based on the adjustment of the hole position and on the premise of ensuring the sectional area of the building block, the block type is redesigned, so that the width of the rib in the building block is approximately equal to the width of two side ribs and the width of the mortar joint. The block group can reach a porosity of more than 90% after being built, and the high porosity is the key for ensuring that a more complete and continuous structure is formed when reinforcing steel bars are inserted into vertical holes and concrete is poured in the future, so that the safety of the structure is guaranteed, and the performance of a wall body is fully reflected.
The wall thickness of the building block is generally about 30mm, the wall thickness of the mortar sitting surface is different from that of the mortar spreading surface, the wall thickness can be measured by 30mm on the whole, a large hole can be guaranteed, the mechanical property of the building block can also be guaranteed, the bearing capacity of the building block can be reduced by the wall thickness which is too small, and the building block can be damaged seriously in use.
The block type reduction is essentially to replace the block with less open holes with the block with more open slots, and the second block 2 shown in fig. 8 is a new block type by combining the original two symmetrical block types, and the block type is provided with the channels required by the two replaced block types at the same time so as to ensure the passing of the reinforcing steel bars and the concrete.
Assembled arrangement of reinforcement building block masonry wall structure special concrete hollow block product group through "union" principle, reduce the block type through the method that replaces few fluting building blocks with many fluting building blocks, excavated the necessity of this way in technology simultaneously to have the follow-up solution after solving many openings, formed perfect technology, the outstanding quality inspection of using of many openings in the wall piece construction of building by laying bricks or stones, another is the clear of unnecessary masonry mortar and draws.
When used in a wall, an opening is formed in the wall surface, as shown in fig. 9. These openings are not required for structural construction but can be used as inspection openings during the production of the panels to check if excess mortar, which is detrimental to the structural load bearing capacity and which also affects the placement of concrete, has fallen into and adhered to the panels during production (masonry). The inspection opening can simultaneously inspect the arrangement quantity and the position of the reinforcing steel bars. Before the concrete of the wall body is poured, the openings need to be sealed, and the reliability of sealing is ensured, so that the concrete is prevented from leaking when the concrete is poured.
The above-mentioned embodiments further explain the objects, technical solutions and advantages of the present invention in detail. It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the present invention, and that any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention may be made without departing from the scope of the present invention.
