Problems solved by technology

[0002] With the development of society and the advancement of science and technology, in this stage of rapid development of infrastructure construction, fewer and fewer construction workers are willing to engage in grassroots construction, resulting in higher per capita labor costs and higher input costs.
At present, construction projects are mainly reinforced concrete structures, and the production and installation of steel bars occupy a particularly important position. The speed of steel bar installation directly affects the construction progress of the entire project, especially the connection speed of straight thread sleeves is particularly important. In the construction, most of the straight thread casings are connected manually, which is low in efficiency and high in cost.

Embodiment 1

[0022] The straight thread sleeve connection device of the present invention, such as figure 1 As shown, it includes a reciprocating device and a steel bar socket wrench 3; a piston rod 2 that can move horizontally back and forth is arranged in the reciprocating device; the lower end of the steel bar socket wrench 3 is provided with a socket clamp 4; the piston The front end of bar 2 is flexibly connected with the upper end of steel bar wrench. Also includes a base 5; the longitudinal section of the base 5 is L-shaped; the base 5 includes a vertical section and a horizontal section perpendicular to each other; the aforementioned reciprocating device is fixedly connected to the upper end of the vertical section; the reciprocating device is fixedly arranged on On the base 5, the vertical distance between the piston rod 2 and the horizontal section of the base 5 is equal to the height of the steel bar socket wrench 3; Ensure that the torque of the piston rod 2 transmitted to the...

Embodiment 2

[0026] On the basis of Embodiment 1, the straight thread sleeve connection method of the straight thread sleeve connection device of the present invention includes the following steps: Socketing the end of the steel bar to be connected with the straight thread sleeve;

[0027] The steel bar is fixed by the fixing fixture 6;

[0028] Connect the socket clip 4 of the steel bar socket wrench 3 onto the aforementioned straight threaded socket;

[0029] Start the reciprocating device, the piston rod 2 reciprocates back and forth along the horizontal direction, drives the upper end of the steel socket wrench 3 to move back and forth through the movable connection, and the socket clamp 4 located at the lower end of the steel socket wrench 3 reciprocates to realize the alignment of the straight thread sleeve connect. In the specific implementation process, the speed of the cylinder 1 can be adjusted by the control valve to achieve the purpose of controlling the reciprocating speed of...

Embodiment 3

[0032] On the basis of Embodiment 1 and Embodiment 2, this embodiment takes a certain avenue station project as an example. The diameter of the stressed steel bars of the main structural plate of a certain avenue station is greater than or equal to 20mm, and the station is nearly 600 meters long, and the mechanical connection joints of the steel bars exceed 50,000 pieces, the project volume is large, and the efficiency of manual connection is relatively low. Using straight thread sleeve connection device instead of part of manual connection will greatly shorten the installation time of steel bars, which can effectively shorten the construction period and effectively save costs.

[0033] According to the actual observation and analysis on site, the average number of fastening sleeves per two people per working day is about 60-70, and the whole station requires about 1,550 workers. Calculated at 260 yuan per person per day, the total is 403,000 yuan.

[0034] Using the straight t...

Abstract

The invention discloses a straight thread sleeve connection device and method, and belongs to the field of building construction devices. The straight thread sleeve connection device and method are characterized in that the straight thread sleeve connection device comprises a reciprocating motion device and a rebar sleeve wrench; a piston rod is arranged in the reciprocating motion device; a sleeve clamp is arranged at the lower end of the rebar sleeve wrench; and the piston rod is movably connected with the steel wrench. The straight thread sleeve is sleeved a rebar end socket which needs tobe connected, a rebar is fixed by fixing clamps; the sleeve clamp of the rebar sleeve wrench is sleeved the straight thread sleeve; and the reciprocating motion device is started, the piston rod reciprocates forward and backward in the horizontal direction, the upper end of the rebar sleeve wrench moves forward and backward driven by the reciprocating motion device through movable connection, andreciprocating motion of the sleeve clamp at the lower end of the rebar sleeve wrench realizes connection of the straight thread sleeve. Force is added through machinery, thus torque meets the design requirements, the qualification rate is increased, thus the construction speed is accelerated, the construction period is effectively shortened, the speed can be increased by adjusting a speed controlvalve, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building construction devices, and in particular relates to a straight thread casing connection device and method. Background technique [0002] With the development of society and the advancement of science and technology, in this stage of rapid development of infrastructure construction, fewer and fewer construction workers are willing to engage in grassroots construction, resulting in higher per capita labor costs and higher input costs. At present, construction projects are mainly reinforced concrete structures, and the production and installation of steel bars occupy a particularly important position. The speed of steel bar installation directly affects the construction progress of the entire project, especially the connection speed of straight thread sleeves is particularly important. In most of the construction, the connection of the straight thread casing is mostly done manually, which is inefficient and hi...
