The fastening clamp comprises a plurality of clamp units, wherein each clamp unit consists of a left/right side rod, split bolts, nuts and stop collar rods, grooves are formed in the rod ends of one sides of the left/right side rods, a plurality of holes for threading the split bolts are formed from the middle sections of the left/right side rods to the rod sections on the other sides at an equal interval, the groove rod sections of the left/right side rods are attached to the web side formwork of the stiffened concrete beam, the split bolts are threaded through the middle sections and the tail sections of the left/right side rods, the stop collar rods are arranged on the split bolts at the tail sections in a sleeving way, the nuts of the split bolts in the middle sections of the left/right side rods are tightened, and the web side formwork of the stiffened concrete beam is tightly clamped by the left/right side rods. The fastening clamp has the advantages that the traditional fastening mode of forming the holes in the web of the steel beam and threading the split bolts is replaced by the product, the problems that the inaccurate alignment of formwork holes on the two sides of the beam causes difficult construction and repeated formwork hole forming are effectively solved, and the concrete molding quality is ensured.
Description
Technical field
The present invention relates to the construction of a kind of building structural element, especially relate to a kind of strengthening concrete soffit of girder side template strengthening fixture.
Background technology
Along with the development of society, building is progressively to the future development of Super High, the large scale of construction, and Design of Main Structure adopts the form of structure of steel-mixed also increasing.In steel-concrete structure construction period, the mode of Screw arbor with nut at both-ends, steel tube framework is generally adopted to carry out the reinforcing of section steel beam.The weak point of this reinforcing mode is, need bore a hole on section steel beam web, often there will be the situation that web hole and form plate hole contraposition are inaccurate, and leading Screw arbor with nut at both-ends processed successfully to wearing, cannot cause larger difficulty to constructing, have impact on the progress of engineering.
Summary of the invention
The object of the invention is to provide for prior art weak point that a kind of structure is simple, accelerating construction progress, repeatedly used strengthening concrete soffit of girder side template strengthening fixture.
The object of the invention is to be realized by following measures: a kind of strengthening concrete soffit of girder side template strengthening fixture, it is characterized in that: it comprises some fixture units, described fixture unit is by left/right side lever, Screw arbor with nut at both-ends and nut, spacing loop bar composition, the side rod end of described left/right side lever is provided with groove, the stage casing of left/right side lever has some equally spaced for the through hole of Screw arbor with nut at both-ends to the bar section of opposite side, the groove bar section of described left/right side lever is fitted in the veutro template of strengthening concrete beam, the stage casing of left/right side lever and rear are to being installed with Screw arbor with nut at both-ends, the Screw arbor with nut at both-ends cover limited location loop bar of rear, tighten up the nut of left/right side lever stage casing Screw arbor with nut at both-ends, by the veutro template of left/right side lever clamping strengthening concrete beam.
Described spacing loop bar is saved by left/right loop bar, socket joint and forms, socket joint joint is made up of middle part steel plate with holes and the short sleeve that is welded on steel plate both ends of the surface, the outer rim of described short sleeve is corresponding with the inner chamber of left/right loop bar, and left/right loop bar is enclosed within the short sleeve of socket joint joint.
The wedge angle position of described left/right side lever groove is provided with fixing hole.
Compared with prior art, have employed the strengthening concrete soffit of girder side template strengthening fixture that the present invention proposes, tool has the following advantages: 1) this product instead of traditional perforate on section steel beam web, wear the reinforcing mode of Screw arbor with nut at both-ends, effectively avoid because beam both sides form plate hole and the contraposition of section steel beam web hole are forbidden the constructional difficulties that causes and template to repeat the problem of perforate, ensure that concrete Forming Quality, also stop the generation of the situation such as spillage, honeycomb caused because form plate hole is more.2) strengthening concrete beam is shaping disposablely to put in place, afterwards without the need to repairing.Meanwhile, all components due to reinforcing fixture all do not need to pass from concrete, can recycling rate of waterused 100%, and the processing and fabricating of reinforcing fixture is without difficult point, and fraction is higher.
Accompanying drawing illustrates:
Fig. 1 is the embodiment fixture unit structural representation that the present invention proposes.
Fig. 2 is adjustable spacing loop bar structural representation.
Detailed description of the invention:
Below in conjunction with accompanying drawing, detailed description of the invention is elaborated: one embodiment of the present of invention shown in Fig. 1 ~ Fig. 2.In figure, a kind of strengthening concrete soffit of girder side template strengthening fixture, it comprises: some fixture units, and described fixture unit is by left side bar 1, right-hand rod 2, and Screw arbor with nut at both-ends 3 and nut 4, spacing loop bar 5 form.The side rod end of described left side bar 1, right-hand rod 2 is provided with groove 6, stage casing to the bar section of opposite side of left side bar 1, right-hand rod 2 has some equally spaced for the through hole 7 of Screw arbor with nut at both-ends, the groove bar section of described left side bar 1, right-hand rod 3 is fitted in the veutro template 8 of strengthening concrete beam, stage casing and the rear of left side bar 1, right-hand rod 2 are each to being installed with Screw arbor with nut at both-ends 3, the Screw arbor with nut at both-ends of rear overlaps limited location loop bar 5, tighten up the nut of left side bar 1, right-hand rod 2 stage casing Screw arbor with nut at both-ends, left side bar 1, right-hand rod 2 are clamped the veutro template 8 of strengthening concrete beam.In this structure, left side bar, right-hand rod adopt square steel to make, their stage casing has some equally spaced for the through hole of Screw arbor with nut at both-ends to the bar section of opposite side, the position of left side bar, right-hand rod stage casing and the through Screw arbor with nut at both-ends of rear can be adjusted on demand, to adapt to the strengthening concrete beam of differing heights.
The present invention takes following measure further:
Described spacing loop bar is saved 53 formed by left loop bar 51, right loop bar 52, socket joint, socket joint joint 53 is made up of middle part steel plate 54 with holes and the short sleeve 55 that is welded on steel plate both ends of the surface, the outer rim of described short sleeve is corresponding with the inner chamber of left loop bar 1, right loop bar 2, and left loop bar 1, right loop bar 2 are enclosed within the short sleeve 55 of socket joint joint 53.Change the left loop bar of different length, the length of the spacing loop bar of right loop bar adjustable, to adapt to the strengthening concrete beam of different in width.
The wedge angle position of described left side bar 1, right-hand rod 2 groove 6 is provided with fixing hole.Namely the wedge angle position of groove 6 fits the face of veutro template of strengthening concrete beam, left side bar 1, right-hand rod 2 is fixed in the veutro template 8 of strengthening concrete beam during installation by screw through fixing hole.
When strengthening concrete beam is constructed, some fixture units of the present invention are distributed in the template of strengthening concrete soffit of girder side by designing requirement, clamp these some fixture units respectively and namely complete reinforcing to stiffness concrete beam veutro template.
Performance analysis of the present invention:
