Abstract
The utility model discloses a powerful top pressure-type locker for concrete formworks. The powerful top pressure-type locker for the concrete formworks comprises fasteners, tube clamping bolts and framework supporting bolts. Each fastener is provided with an arc-shaped notch; each fastener is respectively connected with the corresponding tube clamping bolt and the corresponding framework supporting bolt by thread structures; the end part of each framework supporting bolt is provided with a framework supporting piece; each framework supporting piece is expanded relative to the shank body of the corresponding framework supporting bolt. When pillars and beams are cast by adopting the powerful top pressure-type locker disclosed by the utility model, the concrete formworks are spliced according to a required shape, and fixed tubes are erected on the periphery of the relatively encircled concrete formworks. Firstly, the fasteners are clamped onto the fixed tubes, so that the fixed tubes are tightly clamped by the tube clamping bolts. Then, the framework supporting bolts are tightly supported to the concrete formworks, so that the concrete formworks are tightly clamped together. Under the condition that the framework supporting bolts are equal in shank diameter, as the framework supporting pieces are relatively enlarged in boundary dimension, the supporting force of each framework supporting piece can be increased, not only can materials be saved but also the supporting force of each framework supporting bolt can be increased, the fixed tubes cannot downwards slide, and moreover, the goal that the concrete formworks are clamped is achieved.
Description
Technical field

The specific embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Embodiment mono-
As shown in Fig. 3 to 6, a kind of strong roof pressing type concrete blinding locker of the present utility model, comprise fastener 1, clamp bolt 2 and roof bolt 3.
Curve arc sheet in fastener 1, there is arc-shaped notch 10, the stationary pipes 1a that arc-shaped notch 10 sets up outward for fastening concrete blinding 2a.The outer wall of fastener 1 is provided with a circle reinforcement 15.Convex with two locks 11,12 on the outer wall of fastener 1, wherein, lock 11 is near an end of fastener 1, and lock 12 is arranged on the middle part of fastener 1.Have the screwed hole that is communicated with arc-shaped notch 10 on the lock 11 of fastener 1 end, assembling clamp bolt 2 in this screw thread.
One end of clamp bolt 2 is support end, and the other end is bolt head.This support end is stretched in arc-shaped notch 10, and to support the stationary pipes 1a be stuck in arc-shaped notch 10, this support end is flat-head shape or taper.On the inwall of arc-shaped notch 10, this place, support end of corresponding clamp bolt 2 is provided with recess 13.When this support end is squeezed because supporting stationary pipes 1a, outwards expand, swell is while producing distortion, recess 13 can be expanded, swell distortion support end reserves enough spaces, prevent from pulling down the utility model because clamp bolt 2 moves back not in place being difficult to from stationary pipes 1a, thereby guarantee smoothly, rapidly that stationary pipes 1a is clamping in arc-shaped notch 10, or pull down the utility model from stationary pipes 1a.The bolt head of clamp bolt 2 is exposed at outside above-mentioned screwed hole, and this bolt head can adopt the various structures such as square toes, turret head, dormant bolt head, hexagon socket head.
Also have screwed hole on the lock 12 at fastener 1 middle part, the axis of this screwed hole is roughly parallel to the axis A of arc-shaped notch 10, assembling roof bolt 3 in this screwed hole.
One end of roof bolt 3 is handle end 31, is equipped with handle 33 on handle end 31.The other end of roof bolt 3 is equipped with top board part 32, and top board part 32 is and expands shape with respect to the shaft of roof bolt 3.For example, top board part 32 is horn-like or cap shape, and the top board part 32 of cap shape has the top of arching and the flanging of outer folding, the cylindrical or taper in top, taper type.The end that perhaps top board part 32 is arranged on roof bolt 3 forms T-shaped shaft-like.Like this in the situation that the bar footpath of roof bolt 3 is identical, become large because the appearance and size of top board part 32 is relative, can improve top board part 32 and withstand on the pressure on concrete blinding 2a, both can save material, can improve the pressure on top surface of roof bolt 3 again, thereby reach the purpose that clamps concrete blinding 2a.
On fastener 1, lock 12 places at corresponding middle part are provided with flange 14, and flange 14 is arranged on the outer edge that points to handle end 31, and flange 14 stretches out along the axis A of arc-shaped notch 10.When arc-shaped notch 10 is stuck on stationary pipes 1a, due to flange 14, the axis A along arc-shaped notch 10 stretches out, and has increased arc-shaped notch 10 and the contact area of stationary pipes 1a on stationary pipes 1a axis direction.When holding handle 33 rotation roof bolt 3, top board part 32 is tightly compressed on the outer surface of concrete blinding 2a, because flange 14 is against on the outer surface of stationary pipes 1a, limited fastener 1 around the axis A of arc-shaped notch 10 angle of the axis oscillating of stationary pipes 1a in other words, make fastener 1 can only swing small angle, stationary pipes 1a can not produce obvious inclination like this, cause this root stationary pipes 1a be difficult to other stationary pipes 1a between carry out mutually vertical built.
While adopting as shown in figure 15 the present embodiment casting beams, while building pillar as shown in figure 16, at first press required form splicing concrete blinding 2a, stationary pipes 1a is set up in the place needed reinforcement in the concrete blinding 2a periphery relatively enclosed.Then the one side of lock 12 is attached on the outer surface of concrete blinding 2a, stationary pipes 1a is sticked in arc-shaped notch 10, then clamp the thread head of clamp bolt 2 and rotate clamp bolt 2 by the instrument of spanner and so on, make the support end of clamp bolt 2 be against stationary pipes 1a above, thereby stationary pipes 1a tightly is locked in arc-shaped notch 10.Hold handle 33 rotation roof bolt 3, top board part 32 tightly is pressed on the outer surface of concrete blinding 2a.Like this, rely on two lockers that support on the outer surface of relative two block concrete template 2a, thereby make above-mentioned two block concrete template 2a tightly clamp the block concrete template 2a between them, casting concrete 3a in the space then surrounded at concrete blinding 2a.After having built, reverse operating, can pull down locker from stationary pipes 1a.
The projected area be against on concrete blinding 2a due to top board part 32 is larger, can improve the power of compressing, and then improves the chucking power of clamping concrete blinding 2a.And in the situation that reach the identical power that compresses, the bar footpath of roof bolt 3 is less, shaft is thinner, can save a lot of materials, reduce manufacturing cost.
Due to the chucking power that has improved clamping concrete blinding 2a, stationary pipes 1a is landing downwards not, and the concrete blinding 2a enclosed can be not outward-dipping yet, also can save U-shaped folder of using for clamping concrete blinding 2a etc., and it is more convenient to operate.Adopt the utility model, concrete can water and build up the formation that concrete blinding 2a surrounds, and compact density is comparatively desirable.Upper owing to relatively two roof bolt 3 on top can tightly being folded in to concrete blinding 2a, while building like this pillar or beam, not landing downwards or come off of stationary pipes 1a, also improved security.
