Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and specifically provides a modular formwork device for quickly installing and disassembling block-by-block pouring of a foam light soil roadbed. Background Art

[0002] Foamed lightweight soil refers to a new type of engineering material made by mixing cement slurry with foam and other cementitious materials. It is mainly used in roadbed filling, soft foundation treatment, bridge head treatment, highway expansion and abutment backfill applications. Its main characteristics are that its apparent density is smaller than that of ordinary soil, while its strength and deformation characteristics can reach or even exceed those of good soil.

[0003] Foam cement lightweight soil has good fluidity, hydraulic properties, construction performance and economy, and has a very broad application prospect. The basic properties of foam cement lightweight soil materials are generally its apparent density is 700 ~ 1500kg / m 3 Its compressive strength can be adjusted within the range of 0.6-2MPa; its fluidity index, i.e. fluidity, is around 180±10mm, and it can achieve self-leveling effect during construction and pouring.

[0004] In the prior art, during the layered pouring of the roadbed, the pouring height of each layer of the existing foam lightweight soil is 0.5 to 1 m. The traditional plywood formwork is combined with a steel pipe diagonal brace formwork system for block and layer pouring. The same layer can only be poured in separate blocks at a time. After the pouring is completed, the formwork can be removed only after curing to 70% of the design strength, and the middle block area of ​​the same layer can be poured continuously. The formwork process is complicated and the construction speed is slow. In addition, during the block pouring process, the expansion joint foam board is generally not installed in place, which affects the pouring effect of the foam lightweight soil roadbed. Summary of the invention

[0005] The utility model aims at the above-mentioned deficiencies of the prior art and provides a modular formwork device for block casting of foam light soil roadbed with reasonable design, simple structure, safe use and good casting effect, which has the advantages of quick installation and removal.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A modular formwork device for quick installation and disassembly of block-by-block pouring of foam lightweight soil roadbed, comprising a fixed upright assembly, a double T-shaped clamp, an intermediate steel plate and a rectangular deformation joint foam plate, wherein two double T-shaped clamps are spliced ​​with two fixing assemblies by facing tenons to form a formwork fixing assembly;

[0008] The middle steel plate and two rectangular deformation seam foam plates are overlapped and inserted between two connected template fixing components to form a modular template device.

[0009] Furthermore, the double T-shaped clamping plate is composed of a side wall and two vertical walls, the tops of the two vertical walls are provided with eye bolt holes, and a clamping area is formed between the two vertical walls;

[0010] A wide groove is arranged on the side wall in the clamping area, and a back groove is arranged in parallel on the side wall opposite to the wide groove, and the back groove is arranged near the edge of the side wall.

The length of the clamping area is not less than 10cm, the width is 2-3cm, and the depth of the wide groove is not less than 1cm.

[0012] Furthermore, the eye bolt hole is screwed into a reusable eye block, and the reusable eye block is provided with a hole.

[0013] Furthermore, the fixed vertical pole assembly consists of a threaded insertion rod, a locking vertical pole and a lifting ear locking block, the bottom of the locking vertical pole is threadedly connected to the top of the threaded insertion rod, the top of the locking vertical pole is threadedly connected to the bottom of the lifting ear locking block, and the top of the lifting ear locking block is provided with a lifting ear hole.

[0014] Furthermore, the threaded insertion rod is inserted into the ground by at least 30 cm, the ear locking block is installed in the back groove of the two double T-shaped clamps, and the top of the ear locking block is at least 5 cm higher than the top of the double T-shaped clamp, and the ear hole is exposed.

[0015] Furthermore, square lifting ears are welded on both left and right sides of the top of the middle steel plate, and the square lifting ears are provided with square lifting ear holes;

[0018] Compared with the prior art, the modular formwork device for quick installation and removal of block-by-block pouring of lightweight foamed soil roadbed of the utility model has the following outstanding beneficial effects:

[0019] The utility model combines and installs the fixed upright assembly with the double T-shaped clamping plate and the middle steel plate. The front and rear sides of the template system are symmetrical and consistent. The steel pipe diagonal brace in the traditional plywood template system is eliminated to achieve the effect of continuous pouring of the entire layer of foam lightweight soil roadbed, which can greatly reduce the construction period and save manpower.

[0020] The fixed pole assembly, double T-shaped plywood, and the top of the middle steel plate are all equipped with lifting ears. After the single-layer pouring is completed, the steel strands can be passed through the lifting ear holes and a small crane can be used to quickly recover all the formwork components and continue to be used for the next layer of foam lightweight soil pouring construction, which simplifies the construction process of the traditional formwork system. The double T-shaped plywood can fix the expansion joint foam board during the pouring process, thereby improving the quality of the block pouring of the foam lightweight soil roadbed.

[0031] A best embodiment is given below:

[0032] like Figure 1-5 As shown, a modular formwork device for quickly installing and disassembling a foam lightweight soil roadbed in blocks in this embodiment includes a fixed upright assembly, a double T-shaped clamping plate 4, an intermediate steel plate 2 and a rectangular deformation joint foam plate 1. Two double T-shaped clamping plates 4 are spliced ​​with two fixed upright assemblies by facing tenons to form a formwork fixing assembly.

[0033] The middle steel plate 2 and two rectangular deformation joint foam plates 1 are overlapped and inserted between two connected template fixing components to form a modular template device.

[0034] The double T-shaped clamp plate 4 is composed of a side wall 14 and two vertical walls 15. The tops of the two vertical walls 15 are provided with eye bolt holes 5, and a clamping area 17 is formed between the two vertical walls 15.

[0035] A wide groove 6 is provided on the side wall 14 in the clamping area 17 , and a back groove 13 is provided in parallel on the side wall 14 opposite to the wide groove 6 . The back groove 13 is provided near the edge of the side wall 14 .

[0036] In this embodiment, the height of the double T-shaped clamp 4 is 1.4m, which is 10cm higher than the single-layer pouring height of the foam lightweight soil roadbed. The clamping area 17 is 10cm long and 2.5cm wide. The depth of the wide groove 6 is 1cm.

[0037] The eye bolt hole 5 is screwed into the multiple eye block 7 , and the multiple eye block 7 is provided with a hole 11 .

[0038] The fixed vertical pole assembly consists of a threaded insertion rod 10, a locking vertical pole 8 and a lifting ear locking block 9. In this embodiment, the bottom of the locking vertical pole 8 is threadedly connected to the top of the threaded insertion rod 10, and the top of the locking vertical pole 8 is threadedly connected to the bottom of the lifting ear locking block 9, wherein a lifting ear hole 16 is provided at the top of the lifting ear locking block 9.

[0039] In this embodiment, the threaded insertion rod 10 is inserted 30 cm into the ground, the ear locking block 9 is installed at the back groove 13 of the two double T-shaped clamps 4, and the top of the ear locking block 9 is not less than 5 cm higher than the top of the double T-shaped clamp 4, and the ear hole 16 is exposed.

[0040] Square lifting ears 3 are welded on both left and right sides of the top of the middle steel plate 2, and the square lifting ears 3 are provided with square lifting ear holes 12;
