Description

 The invention relates to construction, and in particular to machines used in the field of construction, loading operations, in particular for transportation and installation of building structures, and can be used to move formwork tables during the construction of ceilings from monolithic reinforced concrete.

 Known traverse to move the formwork of monolithic ceilings by ed. St. USSR 1657580, class E 04 G 21/26, 1991, including a U-shaped working body, a sling lever and a locking device in the form of a hydraulic cylinder, a plunger switch mounted on the hydraulic cylinder and a pipe connected to it.

 The disadvantage of this traverse is the increased metal consumption, as indicated by the design of the U-shaped working body, the complexity of the execution of the horizontal mechanism.

 Known traverse to move the formwork of monolithic floors according to the certificate for a utility model of the Russian Federation 13226, class. E 04 G 21/00, 1999, taken by the applicant for the prototype. It contains a working body made of three spatial trusses interconnected by detachable joints, lodgements and a counterweight placed on the lower truss, a sling element installed on the upper truss.

 The drawback of the traverse is that it can not be used for different table sizes, in cramped conditions due to rigidly fixed tool holders, and storage outside the work platform can be accompanied by violation of tool holders, since the traverse is forced to rely on them; inconvenience of slinging the beam, as this requires a ladder.

 An object of the invention is the creation of a universal and mobile construction of the beam, which makes it possible to work in the cramped conditions of the installation of the building, and inoperative store without damage to the lodgements.

 The problem is solved in that in the proposed solution, the traverse is equipped with stops that are installed on the lower truss, and the counterweight is installed on the upper truss, and the lodges and stops are rotatable with the possibility of fixation, the connection of the vertical and upper trusses is hinged, and the upper truss is installed with the possibility of turning on a hinge, the sling element is made in the form of two loops, and the connection of the vertical and upper trusses is equipped with a lock.

 In addition, the mechanism for turning the stops and fixing them in the folded position is made in the form of a rod, and the mechanism for turning the lodgements and fixing them in the folded position is made in the form of a stepped socket and a shaft on which the lodgement is mounted.

 In addition, the lodgements are made telescopic.

 In addition, the lock is made in the form of a bracket and a link connected to it, a pipe is made on the upper truss, and two guide pipes on the vertical truss, and plungers are placed in the guide pipes to interact with the bracket and the pipe.

figure 3 is a section aa in figure 1;
figure 4 is a view of B in figure 1;
figure 5 - view In figure 1, the lock connection of the vertical and upper trusses.

 The traverse consists of three spatial detachable trusses: vertical 1, lower 2 and upper 3. On the lower truss 2 there are stops 4 and tool holders 5 for laying and moving the formwork 6, on the upper truss 3 there is a set-up counterweight 7 and a sling element made in the form of two hinges 8. The connection of the vertical truss 1 and the upper truss 3 is made hinged, while the upper truss 3 is mounted with the possibility of rotation on the hinge 9, that is, it folds. This is on the one hand. And on the other hand, the connection of the vertical truss 1 and the upper truss 3 is equipped with a lock 10, designed to fix (fix) the upper truss 3 in the working position.

 The lodgements 5 are made retractable, telescopic and mounted with the possibility of rotation around its axis and fixation along the lower truss 2. This position is selected in the case of using a traverse in cramped conditions. The rotation mechanism of the lodgements 5 and fixing them in the folded position is made in the form of a stepped socket 11 and a shaft 12, on which the lodgement 5 is mounted.

 The stops 4 are fixed at the bottom of the lower truss 3 and are designed to hold the beam in an upright position near the construction site. The stops 4 are mounted with the possibility of rotation and fixing in a folded position along the lower truss 2 - the position of the stops 4 during transportation of the beam. And the rotation and fixing mechanism of the stops 4 in the folded position is made in the form of a rod 13.

 The lock 10 of the connection of the vertical truss 1 and the upper truss 3 is made in the form of a bracket 14 and a rod 15 connected to it. On the upper truss 3 there is a nozzle 16, and on the vertical truss 1 two guide pipes 17. Inside the guide pipes 17, plungers 18 are installed with the possibility of interaction with bracket 14 and pipe 16.

 Bringing the traverse in working condition is as follows.

 Cranes feed the slings and hook them into loops 8, raise the upper truss 3 to connect it to the vertical truss 1, namely, until the nozzle 16 is aligned with the guide nozzles 17 and is locked with a lock 10 by moving down the rod 15 of the bracket 14, which, acting on its surface on plungers 18, introduces them into the nozzle 16, thereby closing the connection of the nozzles 17 and 16. Then, the lodgements 5 on the shaft 12 are rotated to the working position, if necessary, pushing them to a certain size of the formwork 6. After that, they lift the yoke by turning the rod 13 release the stops 4 and stack them along the lower truss 2. The traverse is ready to work. Then the traverse down under the formwork 6, pick it up and set in place of the erection of the floor.

 Thanks to the use of the proposed technical solution, a universal and mobile construction of the beam has been created, which allows working with formwork in the constrained conditions of the building’s installation, and in the inoperative state it can be stored without damaging the lodgements.
