Problems solved by technology

[0004] Aiming at the problem that the existing prefabricated floor slabs are hoisted and put in place by a cantilever crane, the operation efficiency is low, the positioning accuracy is poor, and there are many safety hazards and great dangers for construction personnel working at heights. The purpose of the present invention is to provide a fast prefabricated floor slab The positioning device and its method utilize the sliding cooperation between the horizontal push rail beam climbing frame and the vertical guide rail and the positioning beam to ensure the positioning accuracy of the prefabricated floor, improve work efficiency, and reduce equipment on the construction site. Large footprint and high-altitude operations ensure construction safety

Embodiment 1

[0027] Example 1: Combining Figure 1 to Figure 6Explain that the quick positioning device 100 for prefabricated floor slabs of the present invention, in order to clarify the direction relationship, sets the xyz Cartesian coordinate system with the z-axis direction as the height extension direction of the prefabricated building frame a as required. It includes a pair of ground tracks 10 arranged on both sides of the prefabricated building frame a; at least one U-shaped track frame 20 that can slide along the ground track 10; A pair of vertical guide rails 21, a crossbeam 22 in place located above the prefabricated building frame a and connected between the pair of vertical guide rails 21; It is used for hoisting the climbing frame 30 of the horizontal pushing guide rail crossbeam of the prefabricated floor slab a'. The above-mentioned horizontal pushing guide rail crossbeam climbing frame 30 is connected with the power control system (not shown in the figure), and is used to ...

Embodiment 2

[0037] Embodiment two: combine Figure 1 to Figure 6 Illustrate the quick positioning method of prefabricated floor slabs of the present invention, the specific steps are as follows:

[0038] S101: if figure 1 As shown, assemble the prefabricated floor quick positioning device 100 so that it is enclosed on the top and both sides of the prefabricated building frame a;

[0039] S102: At the initial position, hang the prefabricated floor slab a' on the climbing frame 30 of the horizontal push guide rail crossbeam; figure 2 As shown, the horizontal push guide rail crossbeam climbing frame 30 is lifted upwards along the vertical guide rail 21 to the same height as the in place crossbeam 22 through the power control system; image 3 As shown, after the frame body 31 of the horizontal push guide rail beam climbing frame 30 is docked with the in-place beam 22, the guide rail beam 34 is controlled to move horizontally along the in-place beam 22, and the prefabricated floor a' is ho...

Abstract

The invention discloses a quick locating device and method for prefabricated floor slabs, relates to the technical field of building construction and aims at solving the problems that due to the fact that existing prefabricated floor slabs are hoisted and located through a cantilever crane, operation efficiency is low, locating precision is poor, and many potential safety hazards exist when constructors work high above the ground.The locating device comprises a pair of ground tracks arranged on the two sides of an assembled building frame, at least one U-shaped track frame capable of sliding along the ground tracks and at least one horizontal push guide rail beam climbing frame capable of being in sliding fit with vertical guide rails and locating beams; each U-shaped track frame comprises a pair of vertical guide rails arranged on the ground tracks on the two sides respectively and a pair of locating beams located above the assembled building frame and connected between the vertical guide rails.According to the locating method, the quick locating devices of the prefabricated floor slabs are arranged on the top and the two sides of the assembled building frame in a surrounding mode, and vertical climbing and horizontal movement of the prefabricated floor slabs are realized by means of sliding of the horizontal push guide rail beam climbing frame along the vertical guide rails and the locating beams.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and method for quickly placing a prefabricated floor slab in the construction process of a prefabricated assembled building. Background technique [0002] Prefabricated buildings are prefabricated parts or all of the components in the factory and transported to the construction site, and the components are assembled through reliable connections. It has high production efficiency, fast construction progress, good component quality, and less on-site wet work. , and the advantages of being less restricted by climatic conditions. [0003] In the construction process of existing prefabricated buildings, cantilever cranes are often used to hoist the prefabricated floors and put them in place, which has the following defects: 1. The cantilever cranes can only lift the prefabricated floors to the vicinity of the predetermined position, and manually push and pull th...
