Description
Technical field
The invention belongs to building implements and construction field, specifically, the present invention relates to a kind of template fixing to the pull bar combination and use this pull bar to be fixed the job practices of construction to template.
Background technology
It mainly is that the carpenter processes according to the size at scene temporarily that the template of prior art adopts wooden form, then adopts nail to fix, and constructs and removes after complete.Weak point is to waste timber, and efficiency of construction is lower.
Using wider in the prior art is steel form, and steel form adopts snap close to be fixed, and constructs and removes after complete, weak point is that efficiency of construction is lower, and difficulty of construction is large, and the snap close spoilage is also higher, and steel form constant intensity when construction is limited, easily causes construction Deformation.
For the deficiencies in the prior art part, the present invention is proposed.
Summary of the invention
The object of the present invention is to provide the installation of stay in place formwork such as can be used for concrete column, beam, shear wall Large bridge beam column and beam to fix and reinforce fixedly job practices to pull bar and template.
For achieving the above object, the present invention a kind of template fixing to the pull bar combination tool, be used for the fixing of construction formwork, comprise a concrete rod, one core bar is arranged in the concrete rod, and there is screw thread at the core bar two ends, and there is the connection recess that exposes core bar two ends screw thread at the two ends of concrete rod; And threaded rod, an end of threaded rod has screwed hole, and the end of threaded rod passes the preformed hole of construction formwork, screws in the connection recess of concrete rod and being threaded of core bar end.
Described connection recess cross sectional shape is trapezoidal.The endface position at described core bar two ends is in the end face of concrete rod two ends.Described threaded rod is provided with a through hole for the torsion bar insertion of rotating threaded rod with respect to the other end of screwed hole.The end section shape that described threaded rod has a screwed hole be connected recess and cooperate.Comprise that also one screws on the threaded rod to prop up the nut of template.
The present invention also provides a kind of template of using to the template construction method of pull bar combination, may further comprise the steps:
Step 1: join template, according to the size of the selected template of working design;
Step 2: template preformed hole positional punch; Before the punching of template preformed hole, the template with pairing adopts unit's nail temporarily compound first, and unit's nail is carried out removing when template is installed in the job site.
Step 3: the connection recess of concrete rod is aimed at the outboard template preformed hole, at the opposite side of outboard template threaded rod is screwed on the core bar screw thread that connects indent, and nut is screwed on the threaded rod, until prop up template;
Step 4: repeating step 3, the inner side template of matching is installed.
Step 5: the template vertical direction in the outside is installed wooden a tree, used in making timber for boats, wooden a tree, used in making timber for boats is pushed down in the horizontal direction installation fixedly steel pipe, fixedly steel pipe on the horizontal direction is that the threaded rod of every row is installed respectively one in both sides up and down, and adopt E shape steel tube snap close to push down fixedly steel pipe, E shape steel tube snap close is installed on the threaded rod, and adopts nut to fix.
The invention has the beneficial effects as follows: template of the present invention is simple to Tiebar structure, the standardization manufacturing
Be easy to large-scale popularization, easy construction, template construction method efficiency of construction of the present invention is high.
