Description
Technical field
The present invention relates to the cast-in-situ concrete beam technology of construction engineering technical field, especially a kind of unsettled truss mold method of concrete beam.
Background technology
In the building construction process of cast-in-situ concrete beam, the support of template is the key of concrete beam construction.For the construction quality of guaranteeing concrete beam, prevent that template is subjected to displacement distortion in casting process, the template bottom must have the support force of sufficient intensity.At present, it is the supporting way that adopts the console mode steel pipe that the cast-in-situ concrete beam forms supports, especially when the building floor height was higher, the difficulty of construction that causes the console mode steel pipe to support strengthened, and the pillar distortion appears in the console mode steel pipe that causes because of floor height, the strut buckling phenomenon increases; It for the construction of bottom cast-in-situ concrete beam, is located on the ground because the console mode steel pipe supports directly again, and the related console mode steel pipe of the sedimentation of ground self displacement occurs and causes template deformation; The lighter influences the construction quality of concrete beam, and weight person causes the amount of deflection of cast-in-situ concrete beam excessive even accident occurs.The problem that the supporting way of console mode steel pipe exists is: when the headway of beam was higher, template supporting steel pipe consumption was big, and the consumption of diagonal brace, bridging significantly increases especially; Big for the foundation soil water content, when physical features is uneven, cause the ground long processing period, labour intensity is big, construction cost is high and long construction period.
Summary of the invention
The unsettled truss mold method that a kind of concrete beam of providing at the deficiencies in the prior art is provided, this method is applicable to the member of cast-in-situ concrete beam or cast in place concrete plate, adopt unsettled truss support template, changed the mode of traditional console mode steel pipe support shuttering, not only saved backing material, and shortened construction period, reduce construction cost and simplified construction technology.
The concrete technical scheme that realizes the object of the invention is:
A kind of unsettled truss mold method of concrete beam, it comprises the steps:
A), truss and steel corbel designs and produces
According to the kind of engineering structures load and the distribution key element of load, carry out the load force analysis of truss and steel corbel, the working drawing of design truss and steel corbel is implemented the making of truss and steel corbel;
B), the vertical support selected
Choosing carrying wall or column arrange bolt hole as two strong points of cast-in-situ concrete beam at carrying wall or column;
C), steel corbel is installed
In the bolt hole of carrying wall or column, penetrate bolt, four steel corbels are symmetrically placed in the both sides of two columns, be sleeved on the two ends of bolt and adjustment, fastening through installing hole;
D), truss lifting
Lift two width of cloth truss and place the both sides of carrying wall or column respectively, and the supporting seat at the two ends of truss is shelved on the steel corbel top of two columns 1 respectively;
E), scaffolding and guardrail
The frame pipe is overlapped on two truss successively, lays scaffold floor at the frame pipe, and set gradually safety barrier in the both sides of scaffold floor;
F), prop up the concrete beam template
Wooden a tree, used in making timber for boats is placed on two truss successively, and above the wooden a tree, used in making timber for boats and between two carrying walls or the columns, the soffit formwork of a concrete beam props up the side template of concrete beam in the soffit formwork both sides, with perpendicular stupefied and split bolt to soffit formwork and side template location, fastening;
G), implement to check and accept
By designing requirement above-mentioned steps is implemented safety examination and acceptance of engineering quality.
Described truss is plane frame, and its top margin is straight line, and supporting seat is positioned at the two ends of straight line; Described steel corbel is wedge shape casing spare, installing hole lateral direction penetrating steel corbel.
The present invention is applicable to the member of cast-in-situ concrete beam or cast in place concrete plate, adopt unsettled truss support template, changed the mode of traditional console mode steel pipe support shuttering, not only saved backing material, and shortened construction period, reduce construction cost and simplified construction technology.
