The specific embodiment
Be elaborated below in conjunction with the accompanying drawing specific embodiments of the invention.Should be appreciated that the specific embodiment described herein only is used for explanation and explains the present invention, is not construed as limiting the invention.
Said length direction is meant the directions X among Fig. 1 among the present invention; Width is meant the Y direction among Fig. 1; Short transverse is meant the Z direction among Fig. 1; First wall 31 among upper surface Fig. 1, second wall 32 towards the surface of top, the first wall 31 among soffit Fig. 1, the surface towards the below of second wall 32.
As shown in Figure 1; The present invention provides a kind of walling unit; This walling unit comprise the parallel first wall 31 and second wall 32 and be fixedly connected on said first wall 31 and said second wall 32 between first rib 33 and second rib 34; Be formed with hollow bulb 37 between said first rib 33 and the said second rib 34; Said walling unit also comprises first peristome 35 and second peristome 36 between said first wall 31 and said second wall 32, and said first rib 33 is between said first peristome 35 and said hollow bulb 37, and said second rib 34 is between said second peristome 36 and said hollow bulb 37.
Pass through technique scheme; Because walling unit has hollow-core construction; Load-carrying members (like load-bearing pillar) can directly be arranged in the hollow-core construction of walling unit, and need not as traditional solid wall building block, need to pile up in a large number on every side, therefore in load-carrying members (like load-bearing pillar); Walling unit provided by the present invention can be practiced thrift and pile up the engineering time, improves efficiency of construction.
The said first wall 31 and second wall 32 are parallel to each other, make body of wall be piled into the plane easily, are convenient to the carrying out of follow-up works such as fitting up like this.Said first rib 33 and said second rib 34 are fixedly connected between said first wall 31 and said second wall 32, can form hollow-core construction, simultaneously, are fixedly connected the intensity that can improve walling unit again, make said walling unit have higher durability.Said first wall 31, second wall 32, first rib 33 and second rib 34 can be fixed together in several ways, for example carry out bonding through adhesive etc.Certainly, for easily manufactured, reduce cost, preferably, said first wall 31, second wall 32, first rib 33 and second rib 34 are integrally formed, and cast forms like one.
As shown in Figure 1, preferably, the height of said first rib 33, second rib 34, first wall 31 and second wall 32 is identical, and the flush of the upper surface of said first rib 33 and said second rib 34 and said first wall 31 and said second wall 32.Walling unit both had been convenient to make and transportation like this, was convenient to piling up of walling unit again.Simultaneously, the body of wall that utilizes all concordant walling unit of this upper surface and soffit to be piled into has higher intensity.
As shown in Figure 1, preferably, the upper surface of said first rib 33 and/or soffit are provided with recess 38, and the upper surface of said second rib 34 and/or soffit are provided with recess 38.Such structure is set both can saves material, can alleviate the weight of said walling unit again.In addition, can also arrange load-bearing pillar by the length direction (being directions X) along said walling unit at said recess 38 places in case of necessity, to improve the intensity of the body of wall that is piled into by said walling unit.
The cross section of said recess 38 can be different shape, like rectangle, semicircle or irregular figure.Preferably, the shape of cross section of said recess 38 is trapezoidal, as shown in Figure 3.Simultaneously, reduce the intensity of walling unit, should the degree of depth of said recess 38 be limited in the suitable scope in order to prevent said recess 38.Preferably, the degree of depth of said recess 38 be said first rib 33 height 1/10～1/5.
In order further to increase the intensity of said walling unit; The simplified manufacturing technique flow process; Improve said walling unit availability; Preferably, said walling unit has centrosymmetric structure, and said first rib 33 towards the plane of said hollow bulb 37 and the plane towards said hollow bulb 37 of said second rib 34 vertical with the length direction of said first wall 31.Should be noted that the time, the integral body trend of integral body trend that vertically is meant said first rib 33 described herein and said second rib 343 is a vertical relation with the relation of the length direction of said first wall 21.
As shown in Figure 2, preferably, said hollow bulb 37, first peristome 35 and second peristome 36 be shaped as rectangle, and the length of said first peristome 35 and said second peristome 36 be said hollow bulb 33 length 1/3～2/3.In the process of piling up, the space that such structure can provide enough being used to arrange load-bearing pillar can be improved the intensity of body of wall effectively, increases the durability of body of wall.More preferably, the length of said first peristome 35 and said second peristome 36 be said hollow bulb 33 length 1/2.Through such design; Pile up when construction the shape and size by per two adjacent formed said hollow parts of walling unit all the shape and size with said hollow bulb 35 are identical; When the filling concrete mortar; Cement mortar can flow in all hollow parts and the said hollow bulb 35 equably, to improve the intensity of body of wall.Simultaneously, such design makes the load-carrying members that are arranged in the body of wall be evenly distributed, and can more effectively improve the intensity of body of wall.
Certainly, in the present invention, the shape of hollow bulb 25 and peristome 26 is not limited to rectangle, for example can also be circular, semicircle or other irregular figure.The shape of hollow bulb 25 and peristome 26 can be selected according to concrete application scenario to confirm.In addition, the shape of hollow bulb 25 is also not necessarily identical with the shape of peristome 26.
Said walling unit can be processed by material known in those skilled in the art, like concrete, gypsum etc., also can be processed by other material.Said walling unit provided by the present invention is obtained through curing by a kind of material compositions; Contain silica sand, cement, water reducing agent, redispersible rubber powder, fiber and water in this material compositions; Wherein, with respect to the cement of 100 weight portions, the content of said silica sand is the 250-2000 weight portion; The content of said water reducing agent is the 0.5-3.0 weight portion; The content of said redispersible rubber powder is the 0.1-10 weight portion, and the content of said fiber is the 0.1-10 weight portion, and the content of said water is the 15-50 weight portion.
Inventor of the present invention is to being that the walling unit of material of main part has carried out careful research with the silica sand; Be surprised to find that; When adding redispersible rubber powder and fiber, make the intensity of the fragment of brick that makes can reach or be higher than the intensity of concrete fragment of brick, make this walling unit can satisfy building requirements.And when the weight ratio of said fiber and said redispersible rubber powder is 0.5-1.5: in the time of 1, the intensity of the walling unit that makes is higher; More preferably, the weight ratio of said fiber and said redispersible rubber powder is 0.8-1.2: 1, thus a kind of material compositions that is used to prepare walling unit that is very suitable in sand resourceful area application is provided.
Among the present invention; The kind of said fiber has no particular limits; For example can be in synthetic fibers, inorfil (like glass fiber), mineral fibers and the string one or more, the size of said fiber can in very large range change, but inventor of the present invention finds; When using length during as the fiber of 0.1-100 micron, can make the intensity of the walling unit that makes higher as 1-30 millimeter, diameter; More preferably, the length of said fiber is that 5-15 millimeter, diameter are 5-50.
