[utility model content]
Run into technical problems such as can't satisfying construction requirement when special circumstances or specific (special) requirements need certain angle to turn to for overcoming existing box culvert, the utility model provides a kind of prefabricated corner box culvert.
The technical scheme that the utility model solves the prior art problem provides a kind of prefabricated corner box culvert, and it is the hollow box body structure, and both ends open comprises one first connector portions, one second connector portions and a turning point, and the turning point is connected with first and second connector portions.
Preferably, between this prefabricated first and second connector portions of corner box culvert angle between 0 ° to 180 °.
Preferably, the angle between this prefabricated first and second connector portions of corner box culvert is between 0 °-90 ° or 90 °-135 ° or 135 °-180 °.
Preferably, the angle between two of this prefabricated corner box culvert connector portions is 45 °, 90 °, 120 °, 135 °, 150 ° or 165 °.
Preferably, this turning point is a triangle or trapezoidal in the section shape of horizontal direction.
Preferably, the outline line of this turning point is linear, broken line shape or camber line shape.
Preferably, this turning point is one or more.
The prefabricated corner box culvert of the utility model can solve box culvert when constructing simultaneously in many places; Joint produces the technical problem that error needs the low-angle adjustment, and is applied to the situation that box culvert needs 90 ° turning at the parting of the ways or need do other angle adjustment.

[specific embodiment]
In order to make the purpose of the utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing and embodiment, the utility model are further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also accompanying drawing 1-Fig. 2; Be first embodiment of the prefabricated corner box culvert 10 of the utility model, this prefabricated corner box culvert 10 is the body structure of a hollow, both ends open; It comprises one first connector portions 101; One second connector portions, 102, one turning points 103,, chamferings 106, four reinforcing bar beam holes 105 and eight mounting grooves 107 in four.Interior chamfering 106 places four interior angle positions of this prefabricated corner box culvert 10, and reinforcing bar beam hole 105 places interior chamfering 106 places, and chamfering 106 is provided with a mounting groove 107 again respectively in two port a distance of the prefabricated corner box culvert 10 of distance in each.And first and second connector portions 101,102 is connected through turning point 103, and makes 101,102 of first and second connector portions be 165 ° of angles.
First connector portions, 101 integral body are the body structure of the hollow of both ends open, and its transverse cross-sectional shape is a rectangle, and the horizontal direction section shape is rectangle; This first connector portions 101 is divided into port part 1011, connecting portion 1014 and pars intermedia 1013.Port part 1011 has the first step 1012 that concaves;
The structure of second connector portions 102 and first connector portions, 101 structures are basic identical; Difference is that the port part 1021 of second connector portions 102 has cambered outwards second step 1022; And second step 1022 is corresponding with first step 1012, and the two can constitute tongue and groove and connect.
The transverse cross-sectional shape of turning point 103 is identical with first connector portions; Its horizontal direction section shape is an isoceles triangle shape; Its two ends have two joint faces (not label) respectively; This joint face is connected with the connecting portion of first and second connector portions 101,102 respectively, and two joint faces are 15 ° of angles.
