[0002] Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric size, maintain its correct position, and bear the deadweight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] After searching, a Chinese patent with publication number CN113404290A discloses a concrete square column casting formwork and a construction method thereof, which relates to the technical field of concrete construction molds. The concrete square column casting formwork and the construction method thereof, by designing a detachable square column mold, can effectively improve the efficiency of mold disassembly after concrete curing, and the disassembled mold can be used multiple times to reduce construction costs; in addition, the present invention can make the mold cope with the casting of concrete square columns of different heights during actual use by slotting one end of the mold and providing a plug at the other end. Different numbers of molds can be selected to enhance the adaptability of the mold to different construction requirements.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] Although the above-mentioned search patent technology can utilize formwork to cope with concrete pouring construction, according to on-site construction requirements, it is necessary to reinforce and dismantle the formwork of the vertical components of the structure. Usually, due to the narrow space, it is difficult to support and dismantle the formwork, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a narrow space concrete pouring formwork construction device, which is easy to reinforce and dismantle and can recycle materials.

[0007] The technical solution to achieve the purpose of the utility model is: a narrow space concrete pouring formwork construction device, including a base, on which two connecting bolts are pre-embedded, and the base is threadedly connected to a plurality of triangular brackets through the two connecting bolts, and a plurality of formworks are arranged on the surface of the base, and each of the formworks is arranged on one side of the corresponding triangular bracket.

[0008] Preferably, a small bracket is fixedly installed at the bottom of the triangular bracket, and a plurality of connecting bolts are threadedly connected between each triangular bracket and the supporting formwork.

[0009] Preferably, L-shaped bolts are pre-embedded in the surface of the base.

[0010] Preferably, holes adapted to the L-shaped bolts are provided on the surface of the small bracket, and the L-shaped bolts and the small bracket are fixedly installed through nuts.

[0011] Compared with the prior art, the remarkable advantages of the present utility model are as follows:

[0012] First: The present utility model solves the installation problem of removing and installing formwork in a narrow space, enables good disassembly and installation of formwork, and facilitates workers to complete the pouring of concrete.

[0013] Second: By pre-burying connecting bolts and L-shaped bolts, the present utility model improves the stability and firmness of the device and extends the service life of the device.

[0014] It solves the problem that according to the requirements of on-site construction, formwork reinforcement and removal of vertical structural members are required. Usually, due to the narrow space, it is difficult to support and remove the formwork. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a formwork construction device for concrete pouring in a narrow space by improvement. The technical solution of the present utility model is as follows:

[0023] As Figures 1-3As shown in the figure, a formwork construction device for concrete pouring in a narrow space includes a base 1. Connecting bolts II 7 are embedded in the base 1. The base 1 is threadedly connected with a plurality of triangular brackets 2 through the connecting bolts II 7. A plurality of formworks 4 are arranged on the surface of the base 1. Each formwork 4 is arranged on one side of the corresponding triangular bracket 2, which is convenient for later concrete pouring and maximizes the role of the formwork 4.

[0024] Furthermore, a small bracket 5 is fixedly installed at the bottom of the triangular bracket 2. A plurality of connecting bolts I 3 are threadedly connected between each triangular bracket 2 and the formwork 4, improving the practicality of the device.
