Abstract
The invention discloses a building formwork pull rod which comprises a pull rod body arranged between two building formworks. The pull rod body comprises a rod body and connecting portions arranged at two ends of the rod body respectively, cross section of the rod body is round, diameters of sections of two ends of the rod body are unequal, and the rod body forms a conical structure, with a certain oblique angle, similar to die drawing design in a die. After concrete is solidified, the pull rod body can be taken out by knocking from one end smaller in diameter to the other end, larger in diameter, of the rod body, so that great convenience in taking out is realized; sleeving of plastic pipes is not needed, so that a lot of plastic pipes are saved, mounting process of the pull rod is simplified, and cost is lowered greatly; a contact face of the pull rod and a wall is smooth, so that the building formwork pull rod is good in sealing effect during repairing and less prone to water leaking.
Description
Technical field
The present invention relates to a kind of pull bar be applied in construction formwork.
Background technology
Along with the development of building trade, the proportion of cast-in-place concrete structure increases day by day, and labour cost constantly increases, and traditional wooden form intensity is low, can the number of turnover few, need to consume a large amount of timber and manpower; Steel form then weight is large, and the demoulding is difficult, and construction needs plant equipment to assist, and aluminum alloy building template is a kind of novel construction formwork, and it has lightweight, and the number of turnover is many, repeatedly has enough to meet the need low cost and other advantages.Aluminum alloy mould plate generally includes system horizontal, frame system, support column, support keel, the compositions such as construction formwork, construction formwork is generally used for building body of wall, flooring, normally two sides construction formwork supports the use, except being fixed except the construction formwork of two sides by frame system, also pull bar need be set at the interior location of two construction formworks, further reinforcing two construction formwork, be out of shape to prevent concrete spreading, after concrete curing, pull bar need be taken out, conveniently pull bar takes out, traditional way is sheathed plastic pipe on pull bar, but in real process, construction formwork system is generally used for the construction of large-scale flooring, pull bar required for it is a lot, this just causes a large amount of wastes of plastic pipe, and sleeve pipe intricate operation, increase cost.Because want filling-up hole mouth, may may cause uneven or leak by the bad such words of contact surface if former cement contacts with plastic pipe.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of construction formwork pull bar.
The technical solution adopted for the present invention to solve the technical problems is:
Construction formwork pull bar, comprise the pull bar main body be arranged between two construction formworks, described pull bar main body comprises the body of rod and is separately positioned on the connecting portion at body of rod two ends, described body of rod cross section is circular, and the diameter in the cross section at these body of rod two ends is unequal, the body of rod is made to form the conical structure at a band constant slope angle.
Described draft angle is set to 0.2 °-1 °.
Described connecting portion is provided with the connecting hole position corresponding with the installing hole on construction formwork.
Described connecting portion is a flat structure, with the side of construction formwork of fitting.
Described body of rod surface is provided with lube layer or release agent.
The invention has the beneficial effects as follows: construction formwork pull bar, comprise the pull bar main body be arranged between two construction formworks, described pull bar main body comprises the body of rod and is separately positioned on the connecting portion at body of rod two ends, described body of rod cross section is circular, and the diameter in the cross section at these body of rod two ends is unequal, the body of rod forms the conical structure at the similar band constant slope angle designed with withdrawing pattern in mould, after concrete curing, one end less from body of rod diameter is beaten to one end that diameter is larger, pull bar main body can be taken out, take out very convenient, and without the need to sheathed plastic pipe, save a large amount of plastic pipes, and simplify the installation procedure of pull bar, greatly reduce cost, and the contact surface of pull bar and body of wall is smooth, what seal during repairing is effective, not easily occur leaking.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the schematic diagram of the present invention when applying;
Fig. 2 is the close-up schematic view of part A in Fig. 1 of the present invention;
Fig. 3 is structural representation of the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, Fig. 1, schematic diagram when Fig. 2 is the present invention's specific embodiment application, Fig. 3 is the structural representation of the present invention's specific embodiment, as shown in the figure, construction formwork pull bar, comprise the pull bar main body 1 be arranged between two construction formworks, described pull bar main body 1 comprises the body of rod 20 and is separately positioned on the connecting portion 21 at the body of rod 20 two ends, 22, the described body of rod 20 cross section is circular, and the diameter d 1 in the cross section at these body of rod 20 two ends, d2 is unequal, the body of rod 20 is made to form the similar conical structure being with constant slope angle designed with withdrawing pattern in mould, after concrete curing, one end less from the body of rod 20 diameter is beaten to one end that diameter is larger, pull bar main body 1 can be taken out, take out very convenient, and without the need to sheathed plastic pipe, save a large amount of plastic pipes, and simplify the installation procedure of pull bar, greatly reduce cost, and the contact surface of pull bar and body of wall is smooth, what seal during repairing is effective, not easily occur leaking.
In the present invention, described draft angle is set to 0.2 °-1 °, as preferably in the present embodiment, this draft angle is set to 0.5 °, ensures the laser intensity of pull bar, and does not affect the taking-up of pull bar, and offer convenience for follow-up tie rod hole Concrete Filled.
As preferably, described connecting portion 21,22 is a flat structure, with the side of construction formwork of fitting, described connecting portion 21,22 is provided with the connecting hole position corresponding with the installing hole on construction formwork, to facilitate the assembling of pull bar and construction formwork.
In the present invention, for further facilitating the taking-up of pull bar, also at the body of rod 20 surface brush last layer lubrication oil, lube layer can be formed, in addition, also at the body of rod 20 surface spraying release agent, can reach the effect of the taking-up facilitating pull bar equally.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
