Description

Technical Field

[0001] The utility model relates to the technical field of installing steel sleeves in structural beams, in particular to a mould used for fixing the steel sleeves in structural beams. Background Art

[0002] In the construction of building structures, due to the needs of room functions, steel sleeves are often embedded in the structural beams for the passage of ventilation, smoke exhaust, water supply and drainage pipes. During construction, the embedding of these sleeves often conflicts with the installation of beam reinforcement. If the sleeves are installed first and then the beam reinforcement, the installation of the beam reinforcement is difficult. On the contrary, if the beam reinforcement is installed first and then the sleeves are installed, the installation of the sleeves is also difficult.

[0003] At present, the installation of traditional sleeves is as follows: first, when installing the beam reinforcement, use support frames to set up the beam surface reinforcement on both sides of the beam mold, insert the beam stirrups, and insert the beam bottom reinforcement, then tie it up to form a beam skeleton. Before placing the tied beam skeleton into the beam mold, first insert the prepared embedded sleeve into the beam perpendicular to the direction of the beam from the gap between the stirrups on the side of the beam skeleton. After the embedded sleeve is placed in the beam, place short steel bars parallel to the direction of the beam under one end of the sleeve to support the sleeve, and weld it to the bottom of the sleeve, and weld the two ends of the steel bars to the beam stirrups. In the same way, short steel bars are used at the same height at the bottom of the other end of the sleeve to weld and fix them to the sleeve and beam stirrups respectively, and the sleeve can be installed in the beam reinforcement. However, this installation method will have the following technical problems:

[0004] 1. When installing the beam reinforcement, the workers responsible for installing the sleeve should always pay attention to the progress of the beam reinforcement installation, because once the beam frame is placed in the beam mold, it will be affected by the beam reinforcement forming frame, making it impossible to install the sleeve in place.

[0005] 2. Since welding is used between the sleeve and the beam stirrups, welding requires cutting multiple shorter sections of steel bars for connection and fixation, which makes the construction cumbersome and increases the cost of labor and materials. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a mold for fixing a steel casing in a structural beam, which solves the problems mentioned in the background technology.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A mold for fixing steel casing in a structural beam, comprising a U-shaped beam template; the inner cavity of the U-shaped beam template is installed with beam reinforcement, the middle part of the beam reinforcement is installed with a casing assembly, the two ends of the casing assembly are respectively connected to the two ends of the inner cavity wall of the U-shaped beam template, the inner cavity of the U-shaped beam template and the surface of the beam reinforcement are cast with a concrete cross beam, the two ends of the top surface of the U-shaped beam template are respectively installed with floor slab templates, and the top surface of the floor slab template is cast with a floor slab surface layer; the casing assembly comprises a steel pipe, a steel pipe in the middle of the beam reinforcement, and the two ends of the outer surface of the steel pipe are respectively slidably connected with a first PVC casing and a second PVC casing, and the first PVC casing and the second PVC casing are respectively fixedly connected to the inner cavity wall of the U-shaped beam template through round nails.

[0009] Furthermore, the first PVC sleeve includes a mold sleeve, the outer surface of the steel pipe is slidably connected to the mold sleeve, one side of the mold sleeve is fixedly connected to a mold ring sheet, one side of the mold ring sheet has a circumferential array of fixing holes, and one side of the mold ring sheet is fixedly connected to the inner cavity wall of the U-beam template through the fixing holes and round nails.

[0010] Furthermore, the second PVC sleeve adopts the same structure as the first PVC sleeve and is symmetrically installed on the surface of the steel pipe.

[0011] Furthermore, the length of the steel pipe is smaller than the diameter of the inner cavity width of the U-beam template.

[0012] Furthermore, the beam reinforcement includes main beam bars and stirrups. Stirrups are fixedly connected to the outer surface of the main beam bars at equal intervals. There are 4 groups of main beam bars in total, and the main beam bars are fixed around the inner cavity of the stirrups.

[0013] The utility model provides a mold for fixing a steel casing in a structural beam. Compared with the prior art, it has the following beneficial effects:

[0014] The U-shaped beam template makes it convenient to fix the beam reinforcement inside at a later time. At this time, the steel pipe can be quickly fixed in the U-shaped beam template by using the first PVC sleeve and the second PVC sleeve in conjunction with round nails, and the installation position is located inside the beam reinforcement. When pouring beam and slab concrete, the overall displacement of the sleeve assembly can also be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

The length of the steel pipe 31 is less than the inner cavity width diameter of the U-shaped beam template 1.

[0029] By cooperating with the first PVC sleeve 32, the second PVC sleeve 33 and the round nail 34, the steel pipe 31 can be fixed in the middle of the U-shaped beam template 1, and the steel pipe 31 can be installed in the beam reinforcement 2, which is convenient for the later pouring of the concrete beam 4.

[0030] Embodiment 3

[0031] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0032] The beam reinforcement 2 includes a beam main reinforcement 21 and stirrups 22. The outer surface of the beam main reinforcement 21 is fixedly connected with stirrups 22 at equal intervals.

[0033] The working principle and use process of this utility model:

[0034] In use:

[0035] The first step is to assemble the U-shaped beam template 1 and fix the U-shaped beam template with the external rack. After fixing, the floor template 5 is installed and the floor template 5 is fixed with the external rack;

[0036] In the second step, first, the main beam reinforcement 21 and the stirrups 22 are fixed together to form the beam reinforcement 2. At this time, the beam reinforcement 2 is placed as a whole into the assembled U-shaped beam template 1;
