Abstract
The utility model relates to a cable bridge tunnel wall portal protective device used for supporting and protecting a cable bridge tunnel wall portal in building construction. The cable bridge tunnel wall portal protective device comprises a tunnel wall portal (1), a transverse plank (2), vertical planks (3), galvanized steel plates (4), a positioning lock piece (5), bolts (6) and nuts (7). After the tunnel wall portal (1) is arranged in a wall body or a slab steel rib, and then the transverse plank (2) and the vertical planks (3) are stably arranged on the tunnel wall portal (1), two assemblies formed through welding of the galvanized steel plates (4) and the positioning lock piece (5) support the vertical planks (3), then the vertical planks (3) are screwed and locked through the bolts (6) and the nuts (7), and accordingly the stability of the device is achieved. Compared with the prior art, the device is simple in structure and reasonable in design, has the advantages of being simple and convenient to install, simple to operate, good in surrounding appearance quality after the portal is formed and the like, and can be widely used in the field of cable bridge wall penetration.
Description
Relate to field
The utility model relates in a kind of construction work the device that is used for supporting, protecting cable testing bridge hole wall retaining.
Background technology
Cable testing bridge is a support that supports and place cable, be widely used on engineering, as long as cable laying will be used crane span structure, cable testing bridge is as a supporting project of wiring installation, there is no at present special standard instructs, when in construction, cable testing bridge passed body of wall and floor, the conventional way that adopts at present had two kinds: the one, do reservation in main structural engineering; The 2nd, the on-the-spot mode of digging of decoration stage.These two kinds of methods not only easily stay hidden danger of quality, and very large on the impression degree impact of engineering.
Summary of the invention
The purpose of this utility model is to design a kind of cable testing bridge hole wall retaining protective device, and this device can industrialized mass production, installs, uses; and it is convenient to remove; turnover property is strong, can farthest guarantee the construction quality of engineering in the time of operation readiness, improves engineering impression degree.
The basic principle of cable testing bridge hole wall retaining protective device is to utilize the galvanized steel plain sheet of commonly using in present engineering to surround the rectangle cuboid; its internal diameter is that crane span structure outside dimension surrounding adds 50mm; and joint weld is firm; form cable testing bridge hole wall retaining, its length intercepts according to body of wall width or the slab thickness that will pass.Until wall steel bar or the floor bar colligation complete after, it is placed in reinforcing bar, choose subsequently the four suitable planks of the short thickness of block length and be placed in the wall retaining of hole, withstand horizontal two planks so that the inner Stability Analysis of Structures of device with two vertical planks.
two of the galvanized steel plain sheets of intercepting 60mm * 80mm and 20mm * 80mm, get out 6 and the equal-sized circular hole of the diameter of bolt in the centre position of 20mm * 80mm galvanized steel plain sheet, form the location locking plate of this device, locate locking plates difference vertical weldings in the galvanized steel sheet surface of another two 60mm * 80mm with these two subsequently, after cooling, the location locking plate of 2 assemblies is adjacent between the rear vertical plank of laterally putting into hole wall retaining mutually, the location locking plate becomes vertical configuration with horizontal plank, after two galvanized steel plain sheets hold out against and adjust two row circular hole positions with the vertical plank on both sides, two pieces of bolts penetrated successively in the circular hole of locating on locking plate and with nut screwing clamping, fix, device is fixing complete.
cable testing bridge hole wall retaining protective device basic structure is by hole wall retaining (1), horizontal plank (2), vertical plank (3), galvanized steel plain sheet (4), location locking plate (5), bolt (6), nut (7) forms, first hole wall retaining (1) is placed in body of wall or floor bar, subsequently with horizontal plank (2) with vertical plank (3) is stable is placed in hole wall retaining (1), the form that again two groups of members that connected by galvanized steel plain sheet (4) and location locking plate (5) vertical welding is adjacent to mutually with location locking plate (5) is put in horizontal plank (2) and structure that vertically plank (3) forms, galvanized steel plain sheet (4) and vertical plank (3) firmly are adjacent to, penetrate successively two pieces of bolts (6) in circular hole finally, tighten the lock jail with nut (7), the installation of finishing device.0
Compare with existing job practices, the utility model apparatus structure is simple, reasonable in design, can lay flexibly according to the actual conditions of job site, quality, the impression of installing after convenient, hole is shaped are good, improve production efficiency, greatly facilitated construction, can be in this area extensive use.
Can be widely used in cable testing bridge field through walls.
Description of drawings
Accompanying drawing 1 is structural upright schematic diagram of the present utility model.The utility model is comprised of hole wall retaining (1), horizontal plank (2), vertical plank (3), galvanized steel plain sheet (4), location locking plate (5), bolt (6), nut (7), with horizontal plank (2) with after vertically plank (3) firmly is placed in hole wall retaining (1), utilization is supported after vertical plank (3) by galvanized steel plain sheet (4) and two assemblies being welded of location locking plate (5) that with bolt (6) and nut (7), it to be tightened lock firm, the stablizing of implement device.Wherein, the hole wall retaining (1) in device, horizontal plank (2) and vertical plank (3) are the structure of a surrounding sealing in actual applications, and for ease of the displaying of internals structure, the spy removes superstructure in this figure.
Accompanying drawing 2 and accompanying drawing 3 be elevation and the plan view after installing for the utility model.
The specific embodiment
In installation process, first hole wall retaining (1) is placed in body of wall or floor bar, with horizontal plank (2) with vertical plank (3) is stable is placed in hole wall retaining (1), with vertical plank (3), withstand horizontal plank (2) so that the Stability Analysis of Structures of installing subsequently.The form that again two groups of members that connected by galvanized steel plain sheet (4) and location locking plate (5) vertical welding is adjacent to mutually with location locking plate (5) is put in horizontal plank (2) and structure that vertically plank (3) forms, location locking plate (5) becomes vertical configuration with horizontal plank (2), galvanized steel plain sheet (4) firmly is adjacent to and it is supported with vertical plank (3), adjust the position of two row's circular holes, penetrate successively two pieces of bolts (6) in circular hole finally, tighten lock jail, the installation of finishing device with nut (7).
After installing, cable testing bridge hole wall retaining protective device can construct according to next procedure; until body of wall built concrete and smoothly just can be with the utility model after form removal in all taking-ups of other devices except hole wall retaining (1), form hole intact, attractive in appearance.
