Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of auxiliary positioning spare part in the building industry, and specifically relates to a device for auxiliary positioning reserved connecting bolt hole. BACKGROUND

[0002] In the workshop design, the structure form of concrete frame plus combined floor (steel secondary beam plus concrete cast-in-place floor) is often adopted. Among them, the connection design of steel secondary beam and concrete frame main beam is the difficulty, and under normal circumstances, the connection joint of steel secondary beam and main beam can be divided into two kinds of rigid connection and hinged connection, and due to the simple and clear stress of hinged joint, it is convenient for design calculation, and the hinged joint has the advantages of small influence on main beam, and is widely used. But in the actual construction process, due to the inevitable disturbance in the process of concrete pouring, the bolt hole reserved will have different degrees of displacement, if a connection joint in the design drawing involves multiple connecting bolts, once the displacement occurs, the relative position of the connecting bolt hole will change, which will bring great difficulty to the subsequent installation of steel secondary beam connecting bolt.

[0003] Further understanding, the prefabricated concrete main beam and the steel secondary beam are fixedly connected through the connecting bolt, since the connecting bolt needs to be installed when the steel secondary beam is installed, it is necessary to embed the PVC sleeve for reserving the connecting bolt hole when the concrete main beam is prefabricated. In the existing method, the PVC sleeve for reserving the connecting bolt hole is fixed on the stirrup by lashing, and during the pouring of the concrete main beam, the relative position of the PVC sleeve is always paid attention to, and if displacement occurs, it is adjusted in real time. Through personnel management behavior to control, if there is a small deviation, it is difficult to find, and the concrete pouring is usually at night, so it is difficult to use optical measuring instruments, and the relative position of multiple reserved connecting bolt holes is difficult to control, which still has great influence on the subsequent installation of steel secondary beam.

[0018] In order to facilitate the understanding of the utility model, the utility model will be described in more detail below in combination with the drawings and specific embodiments. However, the utility model can be realized in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the utility model more thorough and comprehensive.

[0019] Embodiment 1: in combination Figures 1-4 It is understood that a device for assisting in positioning a reserved connecting bolt hole comprises: a pipe fixing frame 1, the pipe fixing frame 1 is symmetrical, the overall shape is similar to "glasses", the pipe fixing frame 1 is provided with a mounting section 101 for mounting a pre-buried pipe 2, and a connecting section 102 connected with the mounting section 101, and the mounting section 101 is fixedly arranged on the connecting section 102.

[0020] The pipe fixing frame 1 can be formed using HPB300 14 steel bars. The length L of the connecting section 102 depends on the design of the connecting bolt 5; the inner diameter D of the mounting section 101 is related to the design diameter of the connecting bolt 5, and is equal to the outer diameter of the embedded pipe 2, while the inner diameter of the embedded pipe 2 is not less than the design diameter of the connecting bolt 5.

[0021] In use, after the main beam steel bars are bound, the pipe fixing frame 1 is installed on the stirrup at the designed reserved connecting bolt hole position, and the connection mode can be wire binding or electric welding, which can ensure fixed connection. Then the embedded pipe 2 corresponding to the pipe fixing frame 1 is installed at the mounting section 101. Generally, two or more pipe fixing frames 1 are arranged along the axis of the embedded pipe 2 to support and position the reserved connecting bolt hole, so as to ensure the linear direction of the reserved connecting bolt hole. In this way, the relative position of the reserved connecting bolt hole at one position will not change. When installing after subsequent pouring is completed, the reserved connecting bolt hole on the prefabricated concrete main beam 3 is aligned with the mounting hole on the steel secondary beam 4 on both sides, the connecting bolt 5 is then inserted, and then the connecting bolt 5 is screwed with the fastening nut 6 at both ends, which is combined with the reserved connecting bolt hole to form a fixed connection. Figures 3-4 Understand.

[0022] In example 2, the mounting section 101 is inwardly recessed. The mounting section 101 is in the shape of a 270° arc. Such a design saves material while the pipe fixing frame 1 itself has high structural strength, and the large arc ensures that the embedded pipe 2 is stably located therein and will not come out.

[0023] In one embodiment, the mounting section 101 is in the shape of a 210-360° arc. While ensuring that the embedded pipe 2 can be stably fixed, the small arc can save material.

[0024] In one embodiment, the mounting section 101 is outwardly recessed. The recesses of the mounting sections 101 on both sides face outwardly, and generally require a large-arc arcuate structure design to prevent the embedded pipe 2 from coming out.

[0025] In one embodiment, the mounting section 101 is in the shape of a greater-than-270° arc, which prevents the embedded pipe 2 from coming out and improves construction stability.

[0026] In one embodiment, the mounting section 101 is in the shape of a greater-than-270° arc, which prevents the embedded pipe 2 from coming out and improves construction stability.

[0027] Any technical features in the above-described embodiments can be combined in any manner, and, for the sake of brevity, the foregoing description has not described all possible combinations of the technical features. However, it is contemplated that the scope of the disclosure encompasses all possible combinations of the technical features.
