Abstract
The utility model relates to a prefabricated girth groove which is a structural element. The utility model is pressed and moulded with cement concrete through a steel mold. The bottom width of the prefabricated girth groove is equal to the width of the rectangle open cavity groove of a wall body which is corresponding to the prefabricated girth groove. The prefabricated girth groove is laid on the wall body part of a constructing girth one by one to compose the whole girth groove. The steel reinforcement of the girth in the groove is cast and compacted with cement concrete, and a porous floor is arranged on the steel reinforcement to operate to change layers to structure. So the casting and compacting the girth of the utility model has the obvious advantages of simple and flexible construction method, short construction period, low construction cost, large numbers of woods and steel products needed in prime girth manufacturing and a shell plate prefabricating process saving, etc.
Description
The utility model is a kind of building unit.
General multilayer structure and building will be provided with one deck collar tie beam below the floor, more than the door and window, to improve the resistance to overturning and the shock resistance of structure or building.Traditional collar tie beam is the position at corresponding body of wall, with the prefabricated shell of plank on first ailing, or makes prefabricated shell with punching block, adds suitable collar tie beam reinforcing bar and recharges concrete in that prefabricated shell is inboard, and behind the maintenance certain hour, the prefabricated shell of stripping forms.Many with said method making collar tie beam operation, the construction trouble, long in time limit, and consume a large amount of timber or steel, the cost height.
The purpose of this utility model provide a kind ofly can manually directly build on the body of wall, collar tie beam pregroove marks member that its vallecular cavity can hold the collar tie beam reinforcing bar, thereby exempt nail system prefabricated shell of plank or the prefabricated shell of steel plate when casting collar tie beam at the scene.
This collar tie beam pregroove marks is that a bottom width equals that corresponding body of wall is wide, the two ends break-through is opened wide, the rectangular channel of hollow, and the bottom of groove (1) has one to several cementation holes (5), so that seat slurry or cement concrete cement in collar tie beam pregroove marks and body of wall together better; The outside wall surface (3) of two walls (2) of groove is perpendicular to groove bottom, and internal face (4) becomes bevel wedge shape, forms to have tapering and make the vallecular cavity that tilts slightly.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail with an embodiment below in conjunction with accompanying drawing.
This collar tie beam pregroove marks be with a certain proportion of cement concrete through punching block hydraulic press compression moulding, the inside and outside wall hacking forms with water vapour maintenance or natural curing after the demoulding.Width according to general brick wall body, the collar tie beam pregroove marks can be made into specification: long 500 millimeters of cell body, trench bottom (1) is wide 220 millimeters or 240 millimeters, thick 30 millimeters, groove both sides walls (2) are high 250 millimeters, thick 25 millimeters of top, thick 30 millimeters of bottom, outside wall surface (3) is perpendicular to groove bottom, internal face (4) becomes bevel wedge shape, makes vallecular cavity form to move back and pulls out, and promptly forms to have tapering and make the vallecular cavity that tilts slightly.Trench bottom (1) middle part also has the cementation hole (5) of 100 millimeters pros.Every heavily about 20 to 21 kilograms of the cement concrete collar tie beam pregroove marks of above-mentioned specification are suitable for manually building by laying bricks or stones.
On the body of wall position of constructed ring beam, the suitable seat slurry that adds is right after a connection peace with one of prefabricated girth groove and builds on it earlier, consists of whole collar tie beam groove. In groove, add on request then ring beam reinforcing steel bar, just can in groove, water and smash cement concrete, water and smash completely, can at once hollow floor be installed above it, change a layer constructions work. Therefore, application the utility model is cast collar tie beam and had following obvious advantage: one, construction method is easy flexibly, is convenient to the installation of electric wiring; Two, can greatly shorten the construction period, i.e. each dwelling construction of thousand square metres can shift to an earlier date about 25 days and be completed; Three, save a large amount of timber and steel; Four, reduce construction cost.
Claims (2)
1, a kind of collar tie beam pregroove marks that is used to build, be our rectangle elongated slot that open, hollow of two ends break-through, the bottom (1) that it is characterized in that groove has one to several cementation holes (5), trench bottom (1) is wide, and to equal corresponding body of wall wide, the outside wall surface (3) of two walls (2) is perpendicular to groove bottom, internal face (4) becomes bevel wedge shape, forms to have tapering and make the vallecular cavity that tilts slightly.
2, collar tie beam pregroove marks as claimed in claim 1 is characterized in that cell body makes with cement concrete.
