Abstract

The utility model provides a tunnel steel bar support couples reinforcing apparatus relates to the tunnel and struts the equipment field, including U shaped steel support, pull rod, angle coupling board and bolt, the both ends of pull rod are passed through respectively the angle coupling board with two canopies of bolt immobilization connection U shaped steel support through each part interact, becomes a whole with the contact of whole supporting construction to improve wholeness, stability and supporting intensity, the utility model discloses simple structure, construction and installation is convenient, couples two canopy U shaped steel supports, bears the country rock jointly, the common deformation.

Description

A kind of tunnel Steel bar rack connects and adds fixing apparatus

Technical field

The utility model relates to tunnel support equipment technical field, is specifically related to the Steel bar rack connection of a kind of tunnel and adds fixing apparatus.

Background technology

In Tunnel Engineering, often Change in surrounding rocks is big, easily cave in, supporting work seems particularly important, should consider the practical situation of construction process, adjustment constructional method, reinforce supporting in time, avoid tunnel gross distortion, the phenomenon of landslide even occurs, guarantee safety for tunnel engineering and quality are played a part most important.

In actual engineering, tunnel support often adopts U-shaped steel or frame supporting measure, and in the middle of two boron steel framves, normal employing metal truss does suitable reinforcing. This just causes every boron steel frame, and often independent support is to bear confined pressure, and the supporting capacity of reinforcing mat is much weak compared with reinforcing bar, causes the anti-power of surrounding rock supporting uneven, the deformation extent of different Steel bar rack is different, causing destruction in various degree, tunnel deformation is uneven, the serious consequence such as do over again, reprocess. So, it is necessary to current existing supporting construction is improved, increases the globality of its steel reinforcement support structure, make it jointly to bear surrounding rock pressure, common eigenvector.

Practical novel content

For the deficiencies in the prior art, the utility model provides the Steel bar rack connection of a kind of tunnel and adds fixing apparatus, enhances the bulk strength of steel reinforcement support so that the supporting in tunnel is more firmly, reliably.

For realizing above object, the utility model is achieved by the following technical programs:

A kind of tunnel Steel bar rack connects and adds fixing apparatus, comprises U-shaped Steel Bracket, pull bar, curved clamping plate and bolt, and described pull bar two ends are respectively by described curved clamping plate and described bolt, and be fixedly connected U-shaped Steel Bracket described in two canopies.

Further, described pull bar is determined according to the spacing of the U-shaped Steel Bracket in tunnel, and described pull bar length can be 800-1200cm.

The utility model provides a kind of tunnel Steel bar rack and connects and add fixing apparatus, and pull bar two ends are fixedly connected the two U-shaped Steel Brackets of canopy by curved clamping plate and bolt respectively. By the interaction of each parts, whole supporting construction is contacted into as a whole, adds the linking intensity between Steel bar rack, press with jointly bearing, common eigenvector, thus improve globality, stability and supporting intensity.

Embodiment

For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

By reference to the accompanying drawings 1, Fig. 2, Fig. 3 and Fig. 4, the utility model provides the Steel bar rack connection of a kind of tunnel and adds fixing apparatus, such as Fig. 1, comprise U-shaped Steel Bracket 1, pull bar 2, curved clamping plate 3 and bolt 4, described pull bar 2 two ends are by described curved clamping plate 3 and described bolt 4, be fixedly connected U-shaped Steel Bracket 1 described in two canopies, if this kind of dismountable method of attachment is convenient to after making to get rusty change, and can according to the spacing of the size of described U-shaped Steel Bracket 1 and the U-shaped Steel Bracket 1 of two canopies, adjusting bolt perforate, the position of curved Boards wall and the length of described pull bar 2, the length of existing described pull bar 2 is set as 1000cm. Fig. 2 is pull bar 2 detail drawing, comprise front view and vertical view, Fig. 3 is curved clamping plate detail drawing, comprising front view and vertical view, Fig. 4 is the schematic diagram that this device is arranged on the U-shaped Steel Bracket in tunnel, with five these devices left and right each installation two of the U-shaped Steel Bracket in tunnel and above install 1, if country rock intensity is little, can suitably reduce device quantity, if country rock intensity is excessive, also can with suitably increasing device quantity.

Above embodiment is only in order to illustrate the technical solution of the utility model, it is not intended to limit, although the utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein part technology feature is carried out equivalent replacement, and these amendments or replacement, do not make the spirit and scope of the essence disengaging each embodiment technical scheme of the utility model of appropriate technical solution.
