Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a prefabricated beam corrugated pipe positioning bracket. Background Art

[0002] With the development of the economy, the technology of building bridge projects has been continuously improved. Prefabricated and assembled T-beam bridges are easy to construct, save materials, are easy to erect and install, and have a large spanning capacity. They have gradually replaced traditional cast-in-place bridges and are particularly widely used in mountainous areas. The quality of T-beam prefabrication construction affects the entire bridge project.

[0003] After searching, the Chinese patent "A prefabricated T-beam corrugated tube positioning steel bar welding bracket" has the authorization announcement number "CN210060228 U". This patented technology manufactures the bracket according to the design arrangement of the T-beam corrugated tube, and uniformly welds the corrugated tube positioning bars on the T-beam horseshoe reinforcement on the bracket. When tying the T-beam reinforcement skeleton, there is no need to measure and weld the corrugated tube positioning bars one by one, which greatly saves construction time and reduces the height error of the positioning bars. In addition, the corrugated tube positioning steel bars are welded on the bracket, which is more convenient than welding when tying the T-beam reinforcement.

[0004] Although the patented technology solves the problem that the conventional welding of corrugated tube positioning bars is to use a ruler to measure when tying T-beam steel bars, after measuring the design position of a corrugated tube on each horseshoe tendon, a positioning steel bar is welded at that position, because each positioning bar needs to be measured, the repetitive work is very large and the construction efficiency is very low; and the measurement with a ruler is prone to errors, which affects the accuracy of the positioning bar welding position. However, the patented technology requires the manufacture of brackets according to the design arrangement of the T-beam corrugated tube. T-beams of different sizes will be produced at the construction site. This one-piece bracket cannot adapt to corrugated tubes of various sizes, so it is necessary to make the bracket separately, which is more troublesome. Therefore, a prefabricated beam corrugated tube positioning bracket is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated beam corrugated pipe positioning bracket in order to solve the above-mentioned problem, thereby improving the problem that the one-piece bracket cannot adapt to corrugated pipes of various sizes and needs to be separately manufactured, which is more troublesome.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a prefabricated beam corrugated pipe positioning bracket, comprising a crossbeam; a positioning bracket, the positioning bracket comprising a welded steel bar fixedly connected to the surface of the crossbeam, two unidirectional brackets are fixedly connected to the surface of the welded steel bar, a first threaded rod is threadedly connected to the inside of the two unidirectional brackets, the tops of the two first threaded rods are threadedly connected to a bidirectional bracket, and the ends of the two bidirectional brackets that are close to each other are threadedly connected to a second threaded rod.

[0007] Preferably, the one-way bracket is provided with a positioning groove at the connection of the welded steel bars, and the one-way bracket is fixedly connected to the surface of the welded steel bars through the positioning groove, which can make the one-way bracket and the welded steel bars fit better and facilitate workers to perform welding work on the connection between the one-way bracket and the welded steel bars.

[0008] Preferably, the first threaded rod includes a first positive thread portion threadedly connected in the one-way bracket, and the first threaded rod is twisted to drive the one-way bracket to move through the first positive thread portion, so as to facilitate the use of corrugated tubes of different sizes.

[0009] Preferably, the top of the first positive wire thread portion is fixedly connected with a first hand-holding portion, which can ensure that the staff can have a better gripping feeling and prevent the staff from scratching their hands due to gripping the threaded part.

[0010] Preferably, a first reverse threaded portion is fixedly connected to the top of the first hand-held portion, and two of the first reverse threaded portions are respectively threadedly connected to the bottom of two bidirectional brackets. When the first threaded rod is twisted, the unidirectional bracket and the bidirectional bracket can move together, thereby adapting to a wider range of length adjustment, which is larger than the range adaptable to adjusting one bracket alone.

[0011] Preferably, the second threaded rod includes a second positive thread portion threadedly connected to the bidirectional bracket, and the second threaded rod is twisted to drive the bidirectional bracket at one end to move through the second positive thread portion, so as to facilitate the use of corrugated pipes of different sizes.

[0012] Preferably, the top of the second positive wire thread portion is fixedly connected with a second hand-gripping portion, which can ensure that the staff can have a better gripping feeling and prevent the staff from scratching their hands due to gripping the threaded part.

[0013] Preferably, the top of the second hand-held part is fixedly connected to a second reverse threaded portion, and the second positive threaded portion and the second reverse threaded portion are respectively threadedly connected to one end of two bidirectional brackets that are close to each other. This enables the two bidirectional brackets to be driven to move at the same time when the threaded rod is twisted, thereby adapting to a wider range of length adjustment.

[0014] Preferably, a plurality of fixing frames are fixedly connected to the outer surface of the crossbeam, and a corrugated pipe is provided on the inner side of the positioning bracket, which can fix the crossbeam to facilitate cement pouring work at a later stage.

[0015] The beneficial effects of the utility model are:

[0016] 1. Connect the two two-way brackets together through the second threaded rod, and drive the two two-way brackets to move by twisting the second threaded rod until the two two-way brackets can adapt to the size of the corrugated pipe. After that, twist the first threaded rod into the bottom of the two-way bracket, and connect the unidirectional bracket to the bottom of the first threaded rod. Drive the unidirectional bracket and the two-way bracket to move vertically by twisting the first threaded rod to adapt to the height of the corrugated pipe. This can solve the problem that the one-piece bracket cannot adapt to corrugated pipes of various sizes and needs to be made separately, which is more troublesome.

[0017] 2. When the first threaded rod and the second threaded rod need to be twisted, the staff can hold them by means of the first gripping part and the second gripping part, so as to prevent the staff from holding the threaded part and causing scratches on their hands.
