Description
Technical field
The utility model relates to the quick-fried mould of template when preventing fluid concrete in a kind of pull bar for building, the especially construction work and the pull bar for building that uses.
Background technology
Usually in the concreting process of building main body construction such as shear wall or column, usually can produce the quick-fried mould of template, cause the concreting failure because of concrete pressure is excessive.Existing pull bar for building is widely used in the building engineering construction place, usually has the structure that monolithic screw rod or two screw rod middle flat steel bar are connected as a single entity, and restriction protrusion is set on pull bar, in template that concreting adopted not simultaneously, the pull bar that uses can be different, as need on the big mould of the common appellation of building trade, use the time, generally just adopt monolithic screw rod pull bar; In the time need using on the punching block of the common appellation of building trade, the pull bar that just adopts two screw rod middle flat steel bar to be connected as a single entity can certainly adopt monolithic screw rod pull bar usually, just not too convenient fixedly punching block.During use, pull bar passes template and the two ends screw rod is exposed to outside the template, utilize the restriction protrusion qualification template position on the pull bar to determine concreting thickness, utilize the two ends screw rod to be connected common fixed form again with the objects such as steel pipe in the external world, being about to template clamps, in order to template is fixedly prevented in the concreting process of shear wall or column, produce the quick-fried mould of template because of concrete pressure is excessive, speed of application and workmanship have been guaranteed simultaneously, for this reason, builing industry is extensive use of pull bar as the building auxiliary material, and use amount is very big.But, existing pull bar is a monolithic construction, after fixed form and concreting, the centre of pull bar can be fixed in the concrete that solidifies along with concreting for one section, the screw rod that after removing template, also needs to excise the pull bar two ends next processes such as decoration of just plastering, and then finish the integral construction of shear wall or column, the pull bar screw rod of excision can not utilize once more and become waste material and caused the metals resources waste.The metal material resource is very nervous in building trade, and waste material increases makes construction cost high, has correspondingly brought no small burden to building trade, and therefore, there is defective in existing pull bar, need improve.
The utility model content
The purpose of this utility model is to improve on the structure of existing pull bar, and a kind of pull bar for building of avoiding the metals resources waste, reducing construction cost is provided.
Pull bar for building of the present utility model has screw rod, it is characterized in that described screw rod one end is set with coupling nut, and described coupling nut has internal thread, and the cross section of described coupling nut is an annular, and the described screw rod other end is a free end.One end of screw rod described in the utility model is set with coupling nut, both can be that described screw rod one end is directly fixedlyed connected with coupling nut, also can be that described screw rod one end is fixedlyed connected with coupling nut indirectly.
Screw rod described in the utility model is that the existing machinery field has externally threaded cylinder, described screw rod can be that metal material such as steel or iron or copper constitute, certainly in case of necessity, also can be to constitute by other material that reaches the hardness requirement, as the high molecular polymerization plastics etc., or even metal and the common complex screw that constitutes of plastic or other material.
Coupling nut described in the utility model is that the cross section is the coupling nut of annular, it is the coupling nut that outer wall is smooth and periphery is rounded, described coupling nut can be that metal material such as steel or iron or copper constitute, certainly in case of necessity, also can be to constitute by other material that reaches the hardness requirement, as the high molecular polymerization plastics etc., or even metal and the common compound coupling nut that constitutes of plastic or other material.For more firm fixed form, can fixedly install restriction protrusion on the coupling nut of the present utility model, certainly, also can allow described restriction protrusion serve as in case of necessity by the extension of coupling nut.
When using pull bar of the present utility model, can earlier coupling nut be fixedlyed connected by screw thread with extraneous connecting screw rod, promptly use two identical pull bars simultaneously, allow the coupling nut on two pull bars be separately fixed at extraneous connecting screw rod two ends, form and the existing building identical integral structure of pull bar, the termination that allows screw rod on the pull bar serve as extraneous connecting screw rod, the end face that described coupling nut is positioned at screw rod serves as restriction protrusion at this, the effect that pull bar played in clamping template and the concreting process is identical with pull bar with existing building, repeats no more herein.What should be specified is, after concreting is finished and is allowed template break away from, pull bar of the present utility model can by coupling nut be fixed on the extraneous connecting screw rod that solidifies in the concrete and separate, promptly treat rotating rod after the concrete setting, the rounded coupling nut of periphery on the pull bar can be rotated in the concrete that solidifies, and the internal thread that has by coupling nut is realized separating with extraneous connecting screw rod, and then next process such as the decoration of can plastering, finish the integral construction of shear wall or column, in this process, do not need to excise the pull bar screw rod, be that the screw rod that has on the pull bar separates with extraneous connecting screw rod in the lump with the coupling nut on the pull bar, and the pull bar of separating can be once more be connected with other extraneous connecting screw rod, in building engineering construction, using repeatedly, can not become the waste material that can not utilize once more, and then saved metals resources and avoided waste, allow the building engineering construction cost reduce.
For fixedly punching block adaptation concreting construction more easily, can also be provided with flat steel bar on the pull bar in the utility model, described flat steel bar is between screw rod and coupling nut, described flat steel bar one end is fixedlyed connected with coupling nut, and the described flat steel bar other end is fixedlyed connected with screw rod one end.Flat steel bar described here is meant promptly that between screw rod and coupling nut above-mentioned screw rod one end fixedlys connected with coupling nut indirectly.The described flat steel bar other end is fixedlyed connected with screw rod one end, can be to fixedly connected with screw rod one end face in the flat steel bar other end, also can be to fixedly connected with screw rod one end side surface in flat steel bar other end side.
Compared with the aforementioned existing similar products, pull bar for building of the present utility model can dismantle easily and installation utilizes once more, has avoided the metals resources waste, has reduced construction cost.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
