Abstract

The utility model relates to a sound-shield positioning connection frame which is suitable for the field of road traffic. The utility model comprises H-shaped steel columns which are arranged at intervals, both sides of the inner cavity of each H-shaped steel column is provided with four vertical clamping strips which have front, back, left and right symmetry, and the corresponding vertical clamping strips between the adjacent H-shaped steel columns are connected through transverse clamping strips. Thereby, a frame clamping seam which is used for installing and fixing a sound shield is formed between the front and back vertical clamping strips and the front and back transverse clamping strips. The utility model has the advantages that a clamping plate type combined frame is formed by the vertical clamping strips, the transverse clamping strips and the H-shaped columns, a sound blocking plate and a sound absorbing plate are fixed and connected by the frame clamping seam, and thus, the sound blocking plate and the sound absorbing plate can freely extend and contract in frames, and drill holes are not used for connecting. Hence, the deformation of the sound shield and damaged stress are reduced, and the service life of the sound shield is effectively prolonged; the utility model uses square through tubes as the transverse and the vertical clamping strips, the arranged structure is reasonable, the rigidity of the frame is good, connecting screw bolts are concealed in the square through tubes, and thus, the utility model is helpful to protect the screw bolts as well as cause the appearance of the integral frame to be beautiful.

Description

The sound barrier framework that is located by connecting

Technical field

The utility model relates to a kind of sound barrier that is applicable to road traffic field framework that is located by connecting.

Background technology

Sound barrier is by the increasingly extensive industrial circles such as road traffic that are applied to road traffic, particularly city owing to possess good noise elimination deadening.Sound barrier generally includes transparent sound barrier and acoustical board, during use, they are fixed and is connected and extends forward along road by the framework that is located by connecting.The existing continuous type sound barrier framework that is located by connecting is connected to form by angle steel and the band steel column as stull and press strip and H shaped steel, when connecting transparent sound barrier often with boring simultaneously such as press strip, connect by bolt and to be installed on the framework, because transparent sound barrier is different with the coefficient of expansion of metal framework member, installation deviation easily forms stress and concentrates in addition, makes transparent sound barrier in use for some time, expanding with heat and contract with cold cracks and damages, and has shortened the application life of sound barrier.On the other hand, the existing framework that is located by connecting outside connecting bolt all is exposed to, not only influences attractive in appearancely, and is easy to damage bolt, and the reasonability that its structure is provided with is relatively poor.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provides a kind of structure setting and connected mode more to become rationally, the sound barrier that can the prolong sound barrier application life framework that is located by connecting.

The utility model for the technical scheme that the problem that solves above-mentioned proposition proposes is: include the H shaped steel column 6 that is provided with at interval, its difference is to be installed in H shaped steel column inner chamber both sides four vertical clamp bars 5 of symmetry all around, corresponding vertical clamp bar between adjacent H shaped steel column links by horizontal clamp bar 1, forms the shaped as frame crack of installing the fixed sound barrier therefrom between perpendicular, the horizontal clamp bar in front and back.

Press such scheme, described vertical clamp bar 5 is made of square through-pipe, and by the side direction through hole is set, makes the right and left siphunculus by bolt 4 and the corresponding connection of H shaped steel column; Described horizontal clamp bar 1 is made of square through-pipe, links to each other with vertical clamp bar 5 by the lug 3 that is provided with on the vertical clamp bar; Described sound barrier comprises transparent or semitransparent sound barrier 8, also comprises acoustical board 9.

The utility model has the advantages that: 1. have perpendicular, horizontal clamp bar and H type column to constitute the clamping plate type group frame, fix connection sound barrier and acoustical board by the framework crack, they are freely stretched in framework, and need not hole and connect, significantly reduce the distortion of sound barrier thus and damaged stress, effectively prolonged the application life of sound barrier; 2. adopt square through-pipe as horizontal, vertical clamp bar, not only structure is provided with rationally, and frame rigidity is good, and the connecting bolt disappearance had so not only helped the protection of bolt but also made general frame more attractive in appearance in square through-pipe.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include the H shaped steel column 6 that equi-spaced apart is provided with, H shaped steel column lower end and fixture link, be provided with four vertical clamp bars 5 of symmetry all around in H shaped steel column inner chamber both sides, vertical clamp bar is made of square through-pipe, on square through-pipe, offer the side direction through hole, inner small and outside big, the square through-pipe of the left and right sides links to each other with rubber packing 7 in twos by bolt 4, and in centre formation perpends, simultaneously, between each corresponding vertical clamp bar of adjacent H shaped steel column, be connected with horizontal clamp bar 1, laterally clamp bar also is made of square through-pipe, by lug 3 usefulness bolts 2 are set on vertical clamp bar it is connected firmly mutually with horizontal clamp bar, form horizontal crack, below whole framework, be installed on foamed ceramics acoustical board 9, foamed ceramics acoustical board insert is in metal framework 10, make its location by hold-down screw 11, install transparent sound barrier 8 in framework in the square bearer crack, by adjusting horizontal stroke, perpends constitutes a continuous type framework sound barrier thus with transparent sound insulation plate holder tightening position.In addition, according to circumstances, acoustical board also can be installed in the middle part and the top of framework, and corresponding the adjustment done in the position of transparent sound barrier.
