Abstract
The utility model discloses a special hoisting clamp for precast blocks for buildings, which comprises two clamps, a long bolt and a nut; the two clamps are crossed and rotatably fixed together by a pin shaft; the lower end of each clamp is provided with a vertical precast block clamping plate, and the upper end of each clamp is provided with a vertical clamping plate; the precast block clamping plate and the clamping plate are respectively integrally formed or fixed with the clamp into a whole; the opposite surfaces of the two precast block clamping plates are uneven friction surfaces, lifting lugs are fixed at the upper ends of the two clamping plates, and the two clamping plates are tightened and fixed by long bolts and nuts. The special fixture is used for paving and hoisting the concrete precast block, time and labor are saved, the construction efficiency is high, the labor intensity of workers is reduced, the construction cost is low, and the construction is safer.
Description
Technical Field
The utility model relates to a special fixture for hoisting of concrete precast blocks in drainage ditches.
Background
In recent years, China vigorously develops air route construction, more and more airports are built, rebuilt and expanded, and due to the fact that the airports are large in occupied area, the rainwater concrete precast block drainage open ditch becomes one of main partial projects in all airport construction. At present, three methods are generally adopted for paving the concrete precast block of the domestic drainage ditch, and one method is pure manual carrying and installation; one is that after being manually transported to the bottom of the ditch, the ditch is hoisted by a simple bracket by utilizing the lever principle; one is hoisting by using a truck crane. No matter the simple support is hoisted by utilizing a lever principle or the truck crane is hoisted, as long as hoisting of the concrete precast block is completely bound by adopting ropes, the concrete precast block is hoisted to the hook, and the drainage ditch precast block is of a square structure, the weight of each concrete precast block is about 100kg, and the concrete precast block is bound by adopting the ropes, so that the method is time-consuming and labor-consuming, high in labor intensity of workers, high in labor cost, high in construction cost, low in construction efficiency, weak in binding, easy to fall and poor in construction safety.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned problem that exists among the prior art, provide a prefabricated section hoist and mount special fixture for building, adopt this special fixture to carry out the hoist and mount of mating formation of concrete prefabricated section, labour saving and time saving, the efficiency of construction is high, has reduced workman intensity of labour, and construction cost is low, and the construction is safer.
In order to achieve the above object, the technical solution of the present invention is: a special fixture for hoisting a precast block for a building comprises two clamps, a long bolt and a nut; the two clamps are crossed and rotatably fixed together by a pin shaft; the lower end of each clamp is provided with a vertical precast block clamping plate, and the upper end of each clamp is provided with a vertical clamping plate; the precast block clamping plate and the clamping plate are respectively integrally formed or fixed with the clamp into a whole; the opposite surfaces of the two precast block clamping plates are uneven friction surfaces, lifting lugs are fixed at the upper ends of the two clamping plates, and the two clamping plates are tightened and fixed by long bolts and nuts.
Preferably, a diagonal brace is welded and fixed between the clamp and the clamping plate. Increase the supporting strength of the utility model.
Adopt the utility model discloses carry out the concrete precast block mat formation hoist and mount construction, labour saving and time saving, the efficiency of construction is high, has reduced workman intensity of labour, and construction cost is low, and the construction is safer.
Drawings
Fig. 1 is a schematic front view of the present invention.
Detailed Description
The present invention will be further described with reference to the following embodiments.
As shown in fig. 1, the present embodiment includes two clips 7, a long bolt 2, and a nut 5; the two clamps 7 are fixed together by the pin shaft 4 in a crossed and rotatable way; the lower end of each clamp 7 is provided with a vertical precast block clamping plate 9, and the upper end is provided with a vertical clamping plate 1; the precast block clamping plate 9 and the clamping plate 1 are respectively welded and fixed with the clamp into a whole (or can be integrally formed); the opposite surfaces of the two precast block clamping plates 9 are uneven friction surfaces 8, lifting lugs 3 are welded and fixed at the upper ends of the two clamping plates 1, the two clamping plates 1 are tightened and fixed by long bolts 2 and nuts 5, and the clamping force of the long bolts 2 and the nuts 5 is selected according to the weight of the concrete precast block 10. Preferably, a diagonal brace 6 is welded and fixed between the clamp 7 and the clamping plate 1. During the use, directly with the precast concrete block centre gripping between the vertical precast block grip block 9 of two clamps, again with two grip blocks 1 by the taut fixed of stay bolt 2 and nut 5, then on hanging the lug to the couple of crane can.
The above-described embodiments are merely preferred and exemplary and are not intended to limit the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
