Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction device for a supportless steel truss floor deck and precast beam. Background Technology

[0002] Currently, prefabricated structures are widely used in the construction industry. Among them, steel truss floor decking is a new type of material that is lightweight, high-strength, quick to construct, flexible, convenient to construct, and highly adaptable.

[0003] Based on existing technological findings:

[0004] When existing steel truss floor decks are constructed simultaneously with precast beams, a support frame must be erected under the floor deck to ensure the stability of the support during the installation process. This process is cumbersome and wastes a lot of manpower and resources. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a support-free steel truss floor deck and precast beam construction device. By incorporating angle steel, the precast beam body is connected to the steel truss floor deck body, replacing the traditional support frame. This device is simple to operate and saves on erection costs and time.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a construction device for a supportless steel truss floor deck and precast beam, including a precast beam body, a hole provided on the inner side of the precast beam body, a tie rod installed on the inner side of the hole, two angle steels symmetrically installed on the outer side of the tie rod, and two steel pipes symmetrically arranged at both ends of the tie rod, multiple screw holes equally spaced on the inner side of the two angle steels, and a steel truss floor deck body attached to the upper side of the two angle steels.

[0007] In some embodiments, a support frame is provided at the lower position of the precast beam body, and two top supports are symmetrically fixed at the upper end of the support frame.

[0008] In some embodiments, multiple wooden blocks are provided at equal intervals on the upper sides of the two top supports.

[0009] In some embodiments, a plurality of steel reinforcement bodies are provided on the inner side of the steel truss floor deck body.

[0010] In some embodiments, both of the top supports are made of stainless steel.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model uses angle steel to connect the precast beam body with the steel truss floor slab body, replacing the traditional support frame. This simplifies operation and saves on erection costs and time.

[0013] Secondly, this utility model, by symmetrically arranging two steel pipes at both ends of the tie rod, can distribute the force on the tie rod, alleviate the local stress concentration of the tie rod, make the force on the tie rod more uniform, and reduce the deformation and wear of the tie rod.

[0014] This solves the problem of the cumbersome construction process of erecting a support frame under the floor slab when constructing steel truss floor slabs and precast beams simultaneously. Attached Figure Description

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved construction device for unsupported steel truss floor slabs and precast beams. The technical solution of this utility model is as follows:

[0023] like Figures 1-3As shown, a construction device for a supportless steel truss floor deck and precast beam includes a precast beam body 1. The inner side of the precast beam body 1 is provided with holes 2. Tie rods 3 are installed inside the holes 2. Two angle steels 4 are symmetrically installed on the outer side of the tie rods 3. Two steel pipes 31 are symmetrically arranged at both ends of the tie rods 3. Multiple screw holes 5 are opened at equal intervals on the inner side of the two angle steels 4. The steel truss floor deck body 6 is attached to the upper side of the two angle steels 4.

[0024] During the production of the precast beam body 1, holes 2 are reserved at the top of the precast beam body 1 to facilitate the later installation of supporting angle steel 4. During the erection of the support frame 7, only the lower part of the precast beam body 1 is erected, and the lower part of the steel truss floor deck body 6 is not erected. After the precast beam body 1 is installed, tie rods 3 are installed using the reserved holes 2, and angle steel 4 is installed through the tie rods 3. The function of angle steel 4 is to replace the original support frame 7 below the steel truss floor deck body 6. After the angle steel 4 is installed, the steel truss floor deck body 6 is installed. The steel truss floor deck body 6 is fixed to the steel reinforcement of the precast beam body 1 by welding to ensure that the steel truss floor deck body 6 is positioned stably and does not move, so as to ensure construction safety.

[0025] like Figure 1 As shown, in one embodiment, in order to support the precast beam body 1, a support frame 7 is provided at the lower position of the precast beam body 1, and two top supports 8 are symmetrically fixed at the upper end of the support frame 7.

[0026] like Figure 1 As shown, in one embodiment, multiple wooden blocks 9 are provided at equal intervals on the upper sides of the two top supports 8. By providing multiple wooden blocks 9, the concentrated load borne by the support frame 7 can be distributed to multiple contact points, thereby reducing the pressure borne by each contact point and avoiding excessive local pressure.

[0027] like Figure 1 As shown, in one embodiment, a plurality of steel reinforcement bodies 10 are provided on the inner side of the steel truss floor deck body 6, which improves the overall strength.

[0028] like Figure 1 As shown, in one embodiment, both top supports 8 are made of stainless steel, which is economical and durable.

[0029] The specific working method is as follows: During the production of the precast beam body 1, holes 2 are reserved at the top of the precast beam body 1 to facilitate the later installation of supporting angle steel 4. During the erection of the support frame 7, only the lower part of the precast beam body 1 is erected, and the lower part of the steel truss floor deck body 6 is not erected. After the precast beam body 1 is installed, tie rods 3 are installed using the reserved holes 2, and angle steel 4 is installed through the tie rods 3. The function of angle steel 4 is to replace the original support frame 7 below the steel truss floor deck body 6. After the angle steel 4 is installed, the steel truss floor deck body 6 is installed. The steel truss floor deck body 6 is fixed to the steel reinforcement of the precast beam body 1 by welding to ensure that the steel truss floor deck body 6 is positioned stably and does not move, so as to ensure construction safety.
