When the device is used, marks are made at positions where expansion joints are to be arranged, and cement mortar is used for grouting the foam board fixing device, so that the foam board is accurately positioned at the marked positions of the expansion joints; after the cement mortar strength meets the requirements, the formwork is installed, then the drainage ditch is poured by concrete, the foam board fixing device is poured and covered together, and the drainage ditch with the expansion joint foam board is formed after concrete is condensed. The utility model solves the problems that the foam board can not be fixed and is easy to deviate in the concrete pouring process, not only ensures the concrete construction quality of the drainage ditch, but also enhances the leakage resistance of the expansion joint of the drainage ditch.
Description
Technical Field
The utility model relates to a drainage ditch construction technology for constructional engineering.
Background
In the construction of a common drainage ditch, a plain concrete structure is mostly used, the drainage ditch is provided with expansion joints in a certain length to avoid cracks, foam boards are filled between the expansion joints during construction, two methods are mostly adopted for fixing the foam boards in the current construction method, one method is directly bound on a side mold, but the foam boards have low rigidity, so that the fixing measures for the foam boards in the field construction are not in place, the drainage ditch is easy to deviate in the pouring process and even break and damage, and the phenomena of axial deviation and partial section size reduction of the drainage ditch structure are caused; the other method is to cut a small template with the same size as the foam plate, fix the foam plate on the small template after the small template and the drainage ditch side mold are fixed, and the small template is taken out after the drainage ditch is poured by the method, so that the operation is very difficult, the structural appearance quality of the expansion joint is not ideal, and even the anti-leakage performance of the drainage ditch is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a concrete drainage ditch expansion joint foam plate fixing device which not only facilitates the construction of the drainage ditch expansion joint, but also ensures the construction quality of the drainage ditch.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides a concrete escape canal expansion joint cystosepiment fixing device, includes the cystosepiment mount, the cystosepiment mount adopts cement mortar preparation, and it includes 1 rectangle panel, and the back of rectangle panel vertically is equipped with 1 or 2 triangle-shaped floor, uses the whole prefabricated molding of the special examination mould of system.
The optimization scheme is as follows: the 2 foam board mounts are erected and are oppositely placed, the foam board is arranged between the 2 foam board mounts, the upper edge of the foam board is 50-100 mm higher than the rectangular panel, the lower edge of the foam board is 100-200 mm away from the bottom edge of the rectangular panel, and the front surface of the rectangular panel is abutted to the foam board and fixed by transparent adhesive tapes or iron wires.
During use, before concrete of the drainage ditch is poured, marks are made at positions where expansion joints are ready to be arranged, and the foam board fixing device is subjected to mortar sitting by cement mortar to form a temporary fixing seat so that the foam board is accurately located at the marked positions of the expansion joints.
After the strength of the cement mortar of the temporary fixing seat meets the requirement, the template installation is started, then the drainage ditch is poured by concrete, the foam board fixing device is poured and covered together, the vibration is dense, and the drainage ditch with the expansion joint foam board is formed after the concrete is condensed.
The utility model has the following substantive characteristics and progresses:
1. the foam board fixing device is simple in structure and convenient to manufacture;
2. the utility model effectively solves the problems of axial line offset and section size reduction of the drainage ditch structure caused by serious deviation caused by incapability of fixing the foam plate under the impact of concrete or vibration of the vibrating rod in the pouring process, and simultaneously enhances the leakage resistance of the expansion joint;
3. by adopting the utility model, the gaps between the expansion joints of the drainage ditch do not need to be secondarily filled and the appearance of the expansion joints is repaired in the later period, the construction period is saved, and the engineering cost is reduced.

Detailed Description
The utility model is further illustrated by the following specific examples:
examples
Referring to figures 1, 2, 3 and 4,
the utility model provides a concrete escape canal expansion joint cystosepiment fixing device, includes the cystosepiment mount (as shown in figure 1), the cystosepiment mount adopts cement mortar to make, and it includes 1 rectangular panel 1, and the back limit portion of rectangular panel 1 vertically is equipped with triangle-shaped floor 11, uses the whole prefabricated shaping of purpose-made examination mould.
The 2 foam board fixing frames are vertically and oppositely arranged, the foam board 2 is arranged between the 2 foam board fixing frames (as shown in figure 2), the upper edge of the foam board 2 is 100mm higher than the rectangular panel, the lower edge of the foam board 2 is 200mm away from the bottom edge of the rectangular panel 1, and the front surface of the rectangular panel 1 abuts against the foam board 2 and is fixed by transparent adhesive tapes.
Before concrete of the drainage ditch is poured, the position where the expansion joint is to be arranged is marked by paint or spray paint, the foam board fixing device is grouted by cement mortar to form a temporary fixing seat 3, and the foam board 2 is accurately positioned at the marked position of the expansion joint (as shown in figure 3).
After the strength of the cement mortar of the temporary fixing seat 3 meets the requirement, the template installation, the transparent adhesive tape removal of the foam plate fixing device, the concrete pouring drainage ditch, the concrete pouring and covering of the foam plate fixing device, the vibration compaction and the concrete condensation form the drainage ditch 4 with the expansion joint foam plate 2 (as shown in figure 4).
