Abstract

The utility model relates to an adjustable bracing bar used for construction, mainly composed of an inner and an outer tubes, a positioning pin, a locking device and a bar end fastener, wherein, the inner tube is provided with a plurality of pairs of circular holes designed according to the length of standard module; the outer tube is provided with a pair of circular holes at proper positions; the inner and the outer tubes sheathed up can mutually slide, so that some pair of holes on the inner tube are aligned to the holes on the outer tube, and the positioning pin is inserted and fixed in the aligned holes. When any length is needed, the bracing bar can be clamped by the locking device instead of the positioning pin at any required length and fixed for using. The adjustable bracing bar can be used as a cross strut and an inclined strut. When the adjustable bracing bar is used as the inclined strut, the bar end buckle is a structure in which a hinge is connected with a square hook.

Description

Adjustable bracing bar

The utility model relates to a kind of builing industry construction and uses Adjustable bracing bar, belongs to the building operations apparatus.

The structure of the employed bracing frame of early removing system was to determine distance between the column according to the thickness of floor in the past, different distances needs stull and the diagonal brace with different length, therefore needs the stull of plurality of specifications and the needs that diagonal brace is dealt with various structures in actual use.So just essential stull and the diagonal brace of preparing a large amount of different sizes, its versatility is not high, and it is many to overstock equipment, the building costs height.

The purpose of this utility model is according to above-mentioned situation, design a kind of Adjustable bracing bar, can be used for stull and also can be used for diagonal brace, replace the support crosswise of all size, can reduce the quantity that needs usefulness, and uniform specification, easy to operate, in the early removing system, use the adjustable formwork beam in the edge, must be equipped with the adjustable stull of this kind and can put up bracing frame.

Structure of the present utility model is as shown in Figure 1: mainly be made of alignment pin 1, outer tube 2, locking device 4, rod end buckle 8; Have several on the interior pipe 3 to the circular hole of wearing alignment pin 1 by the standard module Design of length, there is a pair of circular hole of wearing alignment pin 1 appropriate location on the outer tube, in can being enclosed within, outer tube 2 slides on the pipe 3, certain of pipe is to the hole on the hole alignment outer tube in making, it is fixing to insert alignment pin 1, can obtain the support bar by the standard module length requirement; Be fixed with two cover locking devices 4 on the outer tube, it is by friction pin 5, carve nail 6, sway chain frame 7 constitutes, stop pin frame 7 is the U-shaped structure, be welded on the outer tube, friction pin 5 is arranged in the frame, carve nail 6, first be rectangular block for a friction pin 5, time connects cylinder, the curved surface of cylindrical lower surface for matching with the outer wall of inner tube radian, be carved with anti-skidding striped on the curved surface, cylinder injects in the hole of opening on the outer wall, and its lower surface contacts with inner tubal wall, have rectangular opening on two walls of stop pin frame 7, cooperate with the nail 6 of carving of rectangle variable cross-section, carve nail 6 and inject in this rectangular opening, can strike tightly and strike pine from the two of carving nail 6, extrusion friction pin 5, make its chucking inner tubal wall or unclamp, carving nail 6 afterbodys has the retaining head, in order to avoid lose.Rod end buckle 8, it is welding side's hook on the disk, the diameter of disk and outer tube are through identical, itself and interior pipe connection are welded on the disk with one section outer tube, the rod end buckle 8 of the other end has same configuration and size, be welded on the outer tube end, rod end buckle 8 can be inserted in buckleing in the bowl square hole of column, and the rod end buckle 8 of stull is as above described, and the rod end buckle of diagonal brace as shown in Figure 3, it is hinge of welding on the disk, hinge connects side's hook, can rotate between square hook and the bar, and diagonal brace passes through rod end buckle 12 oblique cuttings on the rectangle diagonal of stull and column formation, with the rigidity of reinforced liner, diagonal brace rod end buckle also hangs on the connector.

The utility model has the advantages that and to replace existing stull and diagonal brace with Adjustable bracing bar, because be adjustable as the modulus length of standard code, also can be adjusted to the random length that needs, one-object-many-purposes can reduce the quantity of stull and diagonal brace, reduces building costs, it is convenient to use again, in early removing system, use the adjustable formwork beam in the edge, must be equipped with this kind Adjustable bracing bar.

Description of drawings:

Accompanying drawing 1 is the structural representation of Adjustable bracing bar, except that agent structure, and three section AA of still drawing, BB, the CC component can fully disclose the utility model structure, AA represents rod end buckle front view, and BB represents the side view of locking device 4, and CC represents the relation of alignment pin 1 and inner and outer pipes.

Accompanying drawing 2 is the three-dimensional structure diagram of friction pin 5, and the expression rectangular block combines and the abrasive end face situation with cylindrical.

Accompanying drawing 3 is the structure situation of the rod end buckle of inclined support bar.

Number among the figure: 1, alignment pin 2, outer tube 3, interior pipe 4, locking device 5, friction pin 6, carve hole 10, the alignment pin afterbody hinge of opening by standard module length on nail 7, the stop pin frame 8, rod end buckle 9, interior pipe 11, the shelves iron 12 that connects the location division afterbody, the buckle of inclined support bar rod end.

When using Adjustable bracing bar, if standard module length then to the corresponding hole of good inner and outer pipes, is inserted good getting final product with alignment pin 1; If require random length, regulate after the length, horizontal striking carved the wide head of nail, and friction pin 5 is depressed, and inner and outer pipes is fixed, if desire to align length again, horizontal striking carved the nail afterbody, friction pin is become flexible can be regulated.
