Abstract
The utility model is used for construction technical field discloses a rotatory fastener of extension, including rotatory fastener and extension connecting piece, extension connecting piece comprises screw rod and sleeve pipe, and rotatory fastener can be dismantled into two parts, and the part that available extension connecting piece will unpack apart reconnects into wholly, is connected screw rod and half rotatory fastener during the connection, installs the sleeve pipe again, then connects other half, and the end with the screw rod at last is firm with rotatory fastener welding. Because of rotatory fastener can't be connected the outside steel pipe of bridging and support body pole setting in the outside steel pipe cross section of bridging, there is the potential safety hazard, the utility model discloses can effectively solve this problem, strengthen the support body wholeness, reduce outer scaffold frame safety risk, and construction convenience, simple manufacture, repeatedly usable.
Description
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to rotatory fastener of extension especially is applicable to the fixed of outer scaffold frame bridging in the work progress.
Background
When the building engineering is under construction, the outer scaffold is temporary channel and structure for protection, constitute by big or small horizontal pole and bridging, every bridging width is less than 4 strides, and is less than 6m, the inclination of down tube and ground is between 45 to 60, this kind of set up rule has decided that the bridging is fixed on the support body rather than a complete steel pipe by two steel pipe crossovers usually, because the steel pipe of cross point department is more than 2, current rotatory fastener can't fix the steel pipe in the outside in the pole setting, influence safety in utilization to a certain extent.
Disclosure of Invention
The utility model aims to solve the technical problem that a rotatory fastener of extension is provided for the cross steel pipe of fixed bridging reduces safe risk, convenient construction and use.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a rotatory fastener of extension, includes rotatory fastener and extension connecting piece, its characterized in that: the lengthening connecting piece comprises a screw rod and a sleeve, the rotary fastener can be disassembled into two parts, and the disassembled parts can be reconnected into a whole by the lengthening connecting piece.
Preferably, the rotational fastener is removed in two parts from the middle.
Preferably, the screw has a length of 6cm and a diameter of 12 cm.
Preferably, the sleeve has a length of 5cm and an inner diameter of 16-18cm, and is cut and formed from a steel pipe.
Preferably, one half of the disassembled rotating fastener is firstly connected with the screw, then the sleeve is installed, then the other half of the disassembled rotating fastener is installed, and finally the screw and the rotating fastener are firmly welded.
The utility model relates to a rotatory fastener of extension has solved rotatory fastener and can't be in the inside and outside steel pipe cross section of bridging, with the problem that the outside steel pipe of bridging is connected with the support body pole setting, has strengthened support body wholeness and stability, has reduced outer scaffold frame safety risk, and construction convenience, simple manufacture, but reuse.
Description of the drawings:
the invention will be further described with reference to the accompanying drawings and specific embodiments:
FIG. 1 is an exploded view of the present invention;
FIG. 2 is a schematic view of the present invention;
FIG. 3 is a sectional view taken along line A-A;
fig. 4 is a schematic view of the present invention.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, the lengthening rotary fastener comprises a rotary fastener 1 and an lengthening connector 2, wherein the lengthening connector 2 consists of a screw 21 and a sleeve 22.
The screw 21 was machined to a length of 6cm and a diameter of 12 cm.
The sleeve 22 was machined to a length of 5cm and an inner diameter of 16cm and cut into a steel tube.
The rotating fastener 1 is disassembled into two parts from the middle, the screw 21 is connected with one part, then the sleeve 22 is installed, and finally the other part of the rotating fastener 1 is installed, after the installation, the schematic view of the utility model is shown in fig. 2, and the sectional view is shown in fig. 3.
After the installation is finished, the connection point of the screw 21 and the rotating fastener 1 is welded firmly.
When the outrigger is under construction, use in the 5 cross points department of bridging outside steel pipe 4 and inboard steel pipe the utility model discloses, with the direct lock joint of bridging outside steel pipe 4 on support body pole setting 3, cross bridging inboard steel pipe 5, as shown in fig. 4.
After the outer frame is used, the cross braces are detached, and the lengthened rotary fastener and the rotary fastener are stored separately so as to be convenient to circulate.
The utility model relates to a rotatory fastener of extension has following advantage:
with rotatory fastener middle part extension, solved rotatory fastener and can't be in the inside and outside steel pipe cross section of bridging, with the problem that the outside steel pipe of bridging is connected with the support body pole setting, use the utility model discloses strengthen support body wholeness and stability, reduced outer scaffold frame safety risk, and construction convenience, simple manufacture, but reuse.
