Abstract

An adjustable diagonal bracing of a precast concrete slab comprises a first steel pipe and a second steel pipe which are connected by a length adjusting device. Hooks are respectively arranged at two ends of the adjustable diagonal bracing; and sleeves are sleeved outside the hooks and adjustably connected to two ends of the adjustable diagonal bracing through match of threads. When the diagonal bracing needs to be connected with the precast concrete slab, fixing effect is achieved by only using the hooks for hooking embedded reinforcing steel bars inside the precast concrete slab and then rotating the sleeves outwards to tightly clamp the hooks and the embedded reinforcing steel bars, and the whole connection process is enabled to be convenient and rapid through match of the hooks and the sleeves.

Description

The adjustable diagonal brace of precast concrete plank

Technical field

The utility model relates to the bracing or strutting arrangement of using in a kind of construction work, relates in particular to a kind of adjustable diagonal brace of precast concrete plank.

Background technology

Precast concrete plank finish build before, need support by bracing or strutting arrangement.Consult shown in Figure 1, after precast concrete plank 10 sets up, by diagonal brace 11 is set it is provided support power, this diagonal brace 11 is formed with following steel pipe 13 windings by last steel pipe 12, and be connected by a length adjustment device 14 between last steel pipe 12 and the following steel pipe 13, cooperate shown in Figure 2, be respectively arranged with a connecting seat 15 is used for diagonal brace 11 is fixed on precast concrete plank 10 and the base plate 16 at the two ends up and down of diagonal brace 11, its fixed form is: elder generation is pre-buried tapped sleeve in precast concrete plank 10 and base plate 16, Connection Block 15 with diagonal brace 11 two ends aligns with sleeve respectively then, again by the bolt reinforcement by connection.

But there is problem in above-mentioned existing diagonal brace 11: the upper and lower side of diagonal brace 11 is fixing more loaded down with trivial details, need pre-buried tapped sleeve, and each Connection Block 15 all needs being connected with sleeve by bolt, in extensive work progress, can use a large amount of precast concrete planks, if all adopt existing mode to carry out bracing reinforcement, will influence efficient widely.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of adjustable diagonal brace of precast concrete plank, can be connected in quickly and easily on precast concrete plank and the base plate, thereby improve efficiency of construction.

For solving above technical problem, the adjustable diagonal brace of a kind of precast concrete plank that the utility model provides, comprise one first steel pipe and one second steel pipe, be connected by a length adjustment device between described first steel pipe and second steel pipe, the two ends of described adjustable diagonal brace are respectively arranged with a hook, outer cover at described hook is provided with sleeve, and described sleeve is by threaded engagement, adjustable two ends that are connected in described adjustable diagonal brace.

When needs connect diagonal brace and precast concrete plank, only need to hook embedded bar in the precast concrete plank with described hook, again sleeve is outwards rotated clamping hook and embedded bar, thereby play fixing effect, fast convenient by making above-mentioned hook and cooperating of sleeve whole connection procedure.

Further improvement of the utility model is, described first steel pipe socket is located in described second steel pipe, and the spaced apart aperture that is provided with on described first steel pipe, described length adjustment device comprises: first connector, described first connector comprises a master collet and a tapped secondary sleeve, described master collet is sheathed on described first steel pipe, and the spaced apart aperture that is provided with on the described master collet; Second connector, described second connector comprises a master collet and a tapped secondary sleeve equally, and the internal thread of the secondary sleeve of described second connector is offered direction and the internal thread of the secondary sleeve of described first connector, and to offer direction opposite, and described master collet is fixedly arranged on described second steel pipe; Screw rod, the two ends of described screw rod are screwed together in respectively in the secondary sleeve of described first connector and second connector, and radially offer a through hole on the described screw rod.。

The specific embodiment

Consult shown in Figure 3, diagonal brace 20 of the present utility model is assembled by one first steel pipe 21 and one second steel pipe 22, be connected by a length adjustment device 23 between first steel pipe 21 and second steel pipe 22, (promptly first steel pipe 21 and second steel pipe 22 are connected the end of precast concrete plank and base plate respectively) is respectively arranged with a hook 24 at the two ends of diagonal brace 20; Cooperate shown in Figure 4, this hook 24 can be fixed in the end of diagonal brace 20 by the mode of welding, outer cover at hook 24 is provided with sleeve 25, the inwall of this sleeve 25 offers screw thread, and all offer and the corresponding screw thread of sleeve 25 inwalls at diagonal brace 20 two ends, thereby can make sleeve 25 adjustable two ends that are connected in diagonal brace 20.

As preferred embodiment of the present utility model, consult shown in Figure 5, the radius of first steel pipe 21 is smaller than second steel pipe 22, thereby first steel pipe 21 is arranged in described second steel pipe 22, and on

first steel pipe

21,21 offer aperture 211 at interval, the spacing of these apertures 211 generally is controlled at about 100mm, also can change gap length according to actual needs; Again, length adjustment device 23 comprises:

First connector 231, this first connector 231 comprises a master collet 2311 and a tapped secondary sleeve 2312, master collet cover 2311 is sheathed on described first steel pipe and can moves freely up and down, also offers an aperture 2313 on the master collet 2311 simultaneously;

Second connector 232, be similar to first connector, 231 second connectors 232 and comprise a master collet 2321 and a tapped secondary sleeve 2322 equally, and internal thread that should pair sleeve 2322 is offered direction and the internal thread of above-mentioned secondary sleeve 2312, and to offer direction opposite, and this master collet 2321 immovably is fixedly arranged on second steel pipe 22;

Screw rod 233, the two ends of this screw rod 233 have the opposite screw thread of direction respectively and are screwed together in the secondary sleeve of described first connector and second connector, and radially offer a through hole 2331 on the screw rod 233, and instrument can be inserted in this through hole 2331, with rotating screw bolt 233 easily.

Diagonal brace 20 of the present utility model is in use very convenient, cooperate shown in Figure 4, only need embedded bar 26 in precast concrete plank and base plate, hook reinforcing bar 26 with hook 24, thereby again sleeve 25 is covered the opening of hook 24 and clamps embedded bar 26 to inner rotary, just the two ends of diagonal brace 20 can be fixed on precast concrete plank and the base plate; The length that also can utilize length adjustment device 23 to regulate diagonal brace 20 in the use: because first steel pipe 21 is sheathed in second steel pipe 22, the length of whole diagonal brace 20 of the length adjustment that enters second steel pipe 22 that can be by controlling first steel pipe 21, earlier move first steel pipe 21 to appropriate length, aperture 2313 on aperture 211 and the master collet 2311 on 21 aligns on first steel pipe, insert latch, make diagonal brace 20 length and require length difference in 100mm, then latch is inserted the through hole 2331 on the screw rod 233, rotary screw 233, diagonal brace 20 is finely tuned, can adjust to required precise length easily.
