Description

Technical Field

[0001] The utility model belongs to the technical field of highway bridge repair, and particularly relates to a highway bridge concrete repair device. Background Art

[0002] Highway bridges are a kind of application of bridges. According to their shapes, they are divided into box girders and T-shaped girders. Among them, the application of T-shaped girders is relatively common. The horseshoe structure is the structure at the bottom of the T-shaped girder that plays a supporting role. During the use of highway bridges, the horseshoe structure is very easy to be damaged, such as being hit by vehicles, naturally cracked, cracked due to thermal expansion and contraction, etc. Therefore, during the use of highway bridges, once it is found that the horseshoe of the T-shaped girder is damaged, the bridge needs to be repaired immediately.

[0003] During the repair process, it is necessary to chisel the damaged area to remove the repair area, and then formwork and pour concrete. After formwork erection, the concrete enters between the formwork and the repair area and tightly fills the repair area.

[0004] However, in the actual working process, especially when the repair area is relatively large, the stability requirements for the formwork are relatively high. Specifically, a large amount of high-standard concrete is filled between the formwork and the repair area. Under the action of the expansion force of the concrete, conventional formworks are often not resistant to the expansion force of the concrete, resulting in the formwork becoming loose, loose, and bulging. After forming, the repair area cannot achieve the expected effect. As a result, it is more difficult to repair again later.

[0005] Therefore, in the actual construction process, in order to maintain the stability of the formwork, formwork is often supported by multiple steel pipes, but it cannot fundamentally solve the stability of formwork support. It is reflected that once the traditional formwork bulges slightly, even if the support points are increased, it is still easy to leak slurry and bulge after pouring. Content of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a highway bridge concrete repair device, which solves the problem of poor stability of the existing formwork support.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A highway bridge concrete repair device includes fixed beam frames arranged at intervals on both sides;

[0009] The fixed beam frames are fixedly installed at the edge parts of the damaged area of the bridge, and a frame-shaped casting formwork is detachably connected between the fixed beam frames;

[0010] A plurality of casting material pipes are communicated with the top of the frame-shaped casting formwork;

[0011] On the back of the frame-shaped casting formwork, there are installation beam frames arranged at intervals on both sides and fixedly assembled and connected;

[0012] The top and bottom of the installation beam frame are respectively anchored and fixed through connecting pieces;

[0013] In the central part of the frame-shaped casting formwork, an anti-expansion supporting mechanism is detachably installed, and the anti-expansion supporting mechanism includes an I-shaped supporting plate;

[0014] On the I-shaped supporting plate, several support assemblies with adjustable lengths are hinged.

[0015] Preferably, several pouring holes are opened at the top of the frame-shaped casting formwork, and the pouring material pipe is welded on the pouring holes.

[0016] Preferably, the shape of the installation beam frame is I-shaped;

[0017] The connecting piece includes a connecting screw fixedly connected to the installation beam frame, the connecting screw is threadedly connected with an adjusting stud, and an anchoring screw is fixedly connected to the adjusting stud.

[0018] Preferably, the installation beam frame is fastened to the frame-shaped casting formwork through several bolts.

[0019] Preferably, the fixed beam frame includes a fixed beam plate arranged vertically, and several triangular connecting rib plates arranged at intervals up and down are welded between the fixed beam plate and the side wall of the frame-shaped casting formwork;

[0020] Several anchor bolts are slidably connected to the fixed beam plate.

[0021] Preferably, the upper two sides and the lower two sides of the I-shaped supporting plate are respectively detachably installed on the back of the frame-shaped casting formwork through screw structures.

[0022] Preferably, the screw structure includes several screws fixedly connected to the frame-shaped casting formwork;

[0023] The screw penetrates through the I-shaped supporting plate, and a fastening nut is threadedly connected to the screw.

[0024] Preferably, the upper two sides of the I-shaped supporting plate are respectively hinged with support assemblies;

[0025] The lower two sides of the I-shaped supporting plate are respectively hinged with support assemblies.

[0026] Preferably, the support assembly includes a telescopic rod hinged on the I-shaped supporting plate, the telescopic rod includes an inner adjusting rod arranged in a hinged manner and an adjusting sleeve slidably connected to the inner adjusting rod, and an anchoring tongue plate is fixedly connected to the outer end of the adjusting sleeve.

[0027] The utility model has the following beneficial effects:

[0028] 1. During the implementation process, the connecting piece at the bottom is anchored at the bottom of the bridge repair area. The connecting piece at the top position is anchored on the pre-fixed and installed fixed anchor plate in the repair area (during the construction process, the fixed anchor plate is pre-fixed at the upper end of the repair area. The fixed anchor plate has threaded holes, and the connecting piece is anchored). By installing the beam frame - connecting piece, the formwork is fixed in the vertical position, and during the process of pouring and backfilling concrete, the frame-shaped formwork will not expand and open due to the expansion force and will not slip and loosen.

[0029] In the above manner, the frame-shaped formwork covers the pouring area, and after being anchored up, down, left, and right, the formwork does not loosen during the pouring process.

[0037] Embodiment 1

[0038] As Figures 1-4As shown in the figure, a concrete repair device for highway bridges includes fixed beam frames 3 arranged at intervals on the left and right sides; the fixed beam frames 3 are fixedly installed at the edge parts of the damaged areas of the bridges. At the same time, a frame-shaped casting formwork 2 is detachably connected between the fixed beam frames 3. Specifically, the fixed beam frame 3 includes vertically arranged fixed beam plates, and a number of triangular connecting rib plates 31 are welded between the fixed beam plates and the side walls of the frame-shaped casting formwork 2 at intervals up and down. At the same time, a number of anchor bolts 32 are slidably connected to the fixed beam plates.

[0039] During the working process, the anchor bolts 32 are driven into the edge parts of the repair areas (the repair areas of the bridges are pre-excavated, and the damaged concrete is broken). In the above way, the frame-shaped casting formwork 2 is vertically placed and abutted against the repair areas.

[0040] A number of casting material pipes 22 are communicated with the top of the above-mentioned frame-shaped casting formwork 2; specifically, a number of casting holes are opened at the top of the frame-shaped casting formwork 2, and the casting material pipes 22 are welded to the casting holes. During the construction process, concrete is poured from the casting material pipes 22 and filled between the frame-shaped casting formwork 2 and the concrete repair areas.

[0041] The back of the above-mentioned frame-shaped casting formwork 2 is fixedly assembled and connected with installation beam frames 1 arranged at intervals on both sides (the shape of the installation beam frames 1 is I-shaped); at the same time, the installation beam frames 1 are fastened to the frame-shaped casting formwork 2 by a number of bolts.

[0042] At the same time, the top and bottom of the installation beam frame 1 are respectively anchored and fixed through connecting pieces 11; the connecting piece 11 includes a connecting screw 111 fixedly connected to the installation beam frame 1, and the connecting screw 111 is threadedly connected with an adjusting stud 112 (the adjusting stud 112 is provided with a threaded cavity, and a hexagonal convex rib is integrally formed on the outer side wall, which is convenient for the wrench to move), and an anchoring screw 1121 is fixedly connected to the adjusting stud 112.

[0043] During the working process, the connecting piece 11 at the bottom is anchored to the bottom of the bridge repair area. The connecting piece 11 at the top is anchored to the pre-fixed and installed fixed anchor plate in the repair area (during the construction process, a fixed anchor plate is pre-fixed at the upper end of the repair area, and the fixed anchor plate has threaded holes for anchoring the connecting piece). Through the installation beam frame 1 - connecting piece 11, the formwork is fixed in the vertical position, and during the process of pouring and filling concrete, the frame-shaped casting formwork 2 will not expand and slip loose due to the expansion force.

[0044] Similarly, the function of the above-mentioned anchor bolts 32 is to anchor and further reinforce from both sides of the frame-shaped casting formwork 2. The method is: nuts are threadedly connected to the anchor bolts 32. When the fixed beam frames 3 on both sides of the frame-shaped casting formwork 2 are aligned with the anchor bolts 32 pre-driven into the horseshoe parts of the bridge, the frame-shaped casting formwork 2 is vertically installed, and then the nuts are tightened.

[0045] Under the above method, the box-shaped pouring formwork 2 is kept covering the pouring area. After being anchored up, down, left and right, during the pouring process, the formwork does not loosen.

[0046] Embodiment 2

[0047] As Figures 1-4 shown, on the basis of the structure of Embodiment 1 in this embodiment, a swelling prevention and supporting mechanism is detachably installed at the center of the above box-shaped pouring formwork 2. The swelling prevention and supporting mechanism includes an I-shaped supporting plate 4. During the process of pouring concrete by means of the swelling prevention and supporting mechanism abutting against the back of the box-shaped pouring formwork 2, under the supporting action of the swelling prevention and supporting mechanism, it is further avoided that the formwork expands due to the expansion of the concrete.

[0048] Specifically, both sides of the upper end and both sides of the lower end of the I-shaped supporting plate 4 are detachably installed on the back of the box-shaped pouring formwork 2 through screw structures. The screw structure includes a plurality of screws fixedly connected to the box-shaped pouring formwork 2. The screws penetrate through the I-shaped supporting plate 4 (a matching through-hole structure is provided on the I-shaped supporting plate 4), and fastening nuts are threadedly connected to the screws.

[0049] After the box-shaped pouring formwork 2 is installed, align the I-shaped supporting plate 4 with the screws and then fasten the fastening nuts. Under the abutment of the I-shaped supporting plate 4, it is realized that the box-shaped pouring formwork 2 does not deform.

[0050] Meanwhile, a plurality of support components with adjustable lengths are hinged on the above I-shaped supporting plate 4. Specifically, support components are respectively hinged on both sides of the upper end of the I-shaped supporting plate 4; support components are respectively hinged on both sides of the lower end of the I-shaped supporting plate 4.

[0051] The support component includes a telescopic rod hinged on the I-shaped supporting plate 4. The telescopic rod includes an inner adjusting rod 52 with a hinged setting (the inner end of the inner adjusting rod 52 is fixedly connected with an upper hinged ear plate, and a hinged ear seat for hinging is fixedly connected to the I-shaped supporting plate 4. The hinged ear plate is hinged on the hinged ear seat through a pin shaft) and an adjusting sleeve 51 slidably connected to the inner adjusting rod 52. An anchoring tongue plate is fixedly connected to the outer end of the adjusting sleeve 51.

[0052] Meanwhile, in order to lock the telescopic rod after adjusting the length, in the conventional manner disclosed in the prior art, a pinning screw is threadedly connected to the above adjusting sleeve 51, and a plurality of threaded holes are provided on the corresponding inner adjusting rod 52. After loosening the pinning screw, after adjusting the total length of the telescopic adjustment, the pinning screw is pinned in the threaded holes 511 at different positions (pinning in a threaded connection manner). The same as the existing method, then turn over the telescopic rod, and anchor the anchoring tongue plate on the ear seat pre-fixed on the ground through a pin shaft (the shape of the ear seat is rectangular, and two pin rods are welded for pinning the upper and lower parts of the telescopic rod).

[0053] During the pouring process, with the support of the support assembly, the formwork is further kept from loosening and always remains in a tight state, thereby greatly improving the stability of pouring and solving the defects that the formwork is prone to bulge, move, and the sealing performance is reduced and slurry leakage occurs during the pouring process of repairing damaged areas, especially large-area damaged areas.

[0054] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
