Description

Technical Field:

[0001] The utility model belongs to the field of bridge construction, and particularly relates to a mold for the construction of expansion joints of bridge anti-collision walls. Background Art:

[0002] An expansion joint refers to a structural joint provided at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to building components due to climate temperature changes (thermal expansion and contraction). It is widely used in the field of highway bridges. In order to keep the entire beam body stable and ensure safe and comfortable driving, expansion joints must be set at reasonable positions in the bridge structure.

[0003] During the construction of a bridge, expansion joints need to be reserved between two adjacent sections of the bridge, and expansion joints also need to be reserved at the connection of the anti-collision walls poured on both sides of the road. In the prior art, two wooden templates are generally used to support on both sides of the reserved expansion joint for the anti-collision wall. After the anti-collision wall is poured, a crowbar is used to remove the wooden templates. However, this unloading method is likely to damage the wooden templates, resulting in their inability to be reused, and it is also time-consuming and laborious during unloading, affecting the turnover efficiency of the templates and hindering the construction progress of the bridge. When forcefully removing the wooden templates, it is also easy to damage the already poured anti-collision wall, thus destroying the original structural strength of the anti-collision wall. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a mold for the construction of expansion joints of bridge anti-collision walls, and it overcomes the above-mentioned deficiencies of the prior art. It effectively solves the existing problems that the original wooden templates are easily damaged and cannot be reused.

[0005] The content of the utility model: A mold for the construction of expansion joints of bridge anti-collision walls includes two relatively arranged strip-shaped metal baffles, and the two strip-shaped metal baffles are connected by a gap adjusting component.

[0006] Further, the gap adjusting component includes a positive and negative screw nut, and bolts are screwed at both ends of the positive and negative screw nut. The outer ends of the bolts are perpendicularly and fixedly connected to the inner side walls of the strip-shaped metal baffles.

[0007] Further, a number of gap adjusting components are arranged at equal intervals between the two strip-shaped metal baffles.

[0008] Further, the shape of the strip-shaped metal baffle is the same as the cross-sectional shape of the anti-collision wall.

[0009] The beneficial effects of the utility model are as follows: the expansion joint mold composed of two strip metal baffles is used, thereby realizing the block-speed installation and unloading of the expansion joint mold during the casting construction of the crash wall, and the mold is not easily damaged during use, thereby improving the reuse rate and turnover speed of the mold and shortening the construction progress of the bridge construction. Description of the drawings:

[0010] Figure 1 It is the front view of the utility model;

[0011] Figure 2 It is a left view of the utility model;

[0012] Figure 3 It is a cross-sectional view of the gap adjustment component in the utility model;

[0013] In the picture, there are 1 metal baffle, 2 positive and negative thread nuts, and 3 bolts. Specific implementation method:

[0014] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0015] like Figures 1 to 3 As shown, a mold for the construction of expansion joints of bridge crash barriers comprises two oppositely arranged strip metal baffles 1, the two strip metal baffles 1 are connected by a gap adjustment assembly, the gap adjustment assembly comprises positive and negative thread nuts 2, bolts 3 are screwed at both ends of the positive and negative thread nuts 2, the outer ends of the bolts 3 are vertically fixedly connected to the inner walls of the strip metal baffles 1, and a plurality of gap adjustment assemblies are evenly spaced between the two strip metal baffles 1, and the shape of the strip metal baffles 1 is the same as the cross-sectional shape of the crash barrier.

[0016] Specifically, the mold is composed of two strip-shaped metal baffles 1, so that the expansion joint mold can be quickly installed and unloaded during the casting construction of the crash wall.

[0017] In actual use, first assemble the anti-collision wall casting template according to the construction requirements, and fix the expansion joint reserved mold composed of two strip metal baffles 1 at the connection of the two sections of the anti-collision wall casting template. At this time, use a wrench to rotate the positive and negative thread nuts 2, and the two sections of the bolts 3 are separated from each other, so that the two strip metal baffles 1 connected thereto respectively block the gaps of the anti-collision wall casting templates on the left and right sides. When the anti-collision wall is cast, use a wrench to rotate the positive and negative thread nuts 2 in the opposite direction to make the two sections of the bolts 3 approach each other. Under the pull of the bolts 3, the two strip metal baffles 1 also approach each other at the same time, and the demoulding is completed from the cast anti-collision wall;

[0018] A number of gap adjustment components arranged at equal intervals can make the mutual supporting force between the two strip-shaped metal baffles 1 more uniform, thereby preventing the two strip-shaped metal baffles 1 from deforming under external pressure when pouring the anti-collision wall. When unloading the mold, the reverse-thread nuts 2 in the number of gap adjustment components rotate by the same angle, so that the two bolts 3 also move the same distance; the working principle of this gap adjustment component is the same as that of the turnbuckle in the prior art.

[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
