Description

Technical Field

[0001] This utility model relates to the field of T-beam diaphragm construction technology, specifically to an auxiliary device for T-beam diaphragm construction. Background Technology

[0002] A T-beam is a beam with a T-shaped cross-section. The protruding parts on both sides are called flanges, and the middle part is called a beam rib (or web). Since it is essentially formed by removing the tensile concrete zone of a rectangular beam that does not contribute to bending strength, it has the same bending strength as the original rectangular beam, but saves concrete, reduces the self-weight of the component, and improves the span capacity. A diaphragm is a component set between beams to maintain the cross-sectional shape and enhance lateral stiffness. It acts on the live loads distributed on the bridge. Cast-in-place concrete diaphragms are usually used for precast prestressed concrete T-beams. Diaphragms located at the ends of the bridge are called end diaphragms, and diaphragms located in the middle are called middle diaphragms.

[0003] In the actual construction of T-beam diaphragms, a suspended platform is needed to lift the construction workers and then build the formwork for the T-beam diaphragms. This operation is time-consuming, and there are a lot of steel bars between the T-beams, which affects the lifting and movement of the suspended platform. Therefore, it does not meet the existing requirements. To address this, we have proposed an auxiliary device for the construction of T-beam diaphragms. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the construction of T-beam diaphragms, in order to solve the problems mentioned in the background art, which require the use of a suspended platform to lift construction workers and then to build the formwork for the T-beam diaphragms, which is time-consuming and has a large number of steel bars between the T-beams, affecting the lifting and movement of the suspended platform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a T-beam diaphragm construction auxiliary device, comprising a T-beam, with multiple connecting diaphragms on both sides of the T-beam's linear portion, a wrapping template being detachably installed between two adjacent connecting diaphragms, two symmetrically distributed side-closure templates being slidably installed on the inner side of the wrapping template, four guide rods being fixed on one side of the side-closure template, the guide rods passing through the wrapping template and slidably connected to it, and an inclined plate being provided between the guide rods and the wrapping template.

[0006] Preferably, the side-enclosing template faces the surface of the inner wall of the template and is inclined, and the inclined insert is a wedge-shaped block.

[0007] Preferably, the surfaces of the two side-closed templates facing each other are provided with rectangular grooves, and silicone pads are embedded in the inner side of the rectangular grooves.

[0008] Preferably, three tension steel wire ropes are fixed to the top of the wrapping template, and a hanging plate is fixed to the end of the tension steel wire ropes away from the wrapping template. The bottom end of the hanging plate is connected to a fixing screw by a thread, and a fixing plate is installed on the top of the fixing screw.

[0009] Preferably, a manual jack is provided between the tension wire rope and the T-beam, and a support block is fixed to the top of the manual jack. The upper surface of the support block is provided with a U-shaped groove, and the tension wire rope is engaged inside the U-shaped groove.

[0010] Preferably, an anti-friction pad is provided on the outer side of the end of the tension wire rope that connects to the wrapping template. The anti-friction pad is penetrated by the tension wire rope and is slidably connected to the tension wire rope.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model utilizes a wrapping template installed from below the connecting diaphragm to seal the bottom ends of the two connecting diaphragms. Then, two side sealing templates are used to cover and seal the outer sides of the two connecting diaphragms, forming a pouring space between the two connecting diaphragms. This facilitates the pouring of the diaphragms and eliminates the need for manual operation using a suspended platform when setting up the template, reducing the difficulty of template construction and improving construction efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3As shown, a construction auxiliary device for a T-beam diaphragm includes a T-beam 1. Multiple connecting diaphragms 2 are linearly arranged on both sides of the T-beam 1. A wrapping template 3 is detachably installed between adjacent connecting diaphragms 2. Two symmetrically distributed side-sealing templates 11 are slidably installed on the inner side of the wrapping template 3. Four guide rods 12 are fixed on one side of each side-sealing template 11. The guide rods 12 pass through the wrapping template 3 and are slidably connected to it. An inclined plate 13 is provided between the guide rods 12 and the wrapping template 3. The wrapping template 3 is installed from below the connecting diaphragms 2 to seal the bottom ends of the two connecting diaphragms 2. Then, the two side-sealing templates 11 are used to shield and seal the outer sides of the two connecting diaphragms 2, forming a pouring space between the two connecting diaphragms 2, facilitating the pouring construction of the diaphragms.

[0019] The side closing template 11 faces the inner wall of the wrapping template 3 and is inclined. The inclined plate 13 is a wedge-shaped block. The inclined plate 13 enters downward between the side closing template 11 and the wrapping template 3, so that the two side closing templates 11 are close to each other, so that the side closing template 11 is tightly attached to the outer surface of the connecting partition 2.

[0020] The two side-closure templates 11 have rectangular grooves on their surfaces facing each other. A silicone pad is embedded in the inside of the rectangular groove. The silicone pad ensures that the side-closure template 11 and the connecting cross plate 2 are in flexible contact, thereby sealing the gap between the side-closure template 11 and the connecting cross plate 2.

[0021] Three tension steel wire ropes 5 are fixed to the top of the wrapping template 3. A hanging plate 8 is fixed to the end of the tension steel wire rope 5 away from the wrapping template 3. A fixing screw 10 is threaded to the bottom of the hanging plate 8. A fixing plate 9 is installed on the top of the fixing screw 10. The hanging plate 8, the fixing plate 9 and the fixing screw 10 are snapped onto the side of the T beam to suspend and fix the wrapping template 3.

[0022] A manual jack 6 is provided between the tension steel wire rope 5 and the T-beam 1. A support block 7 is fixed to the top of the manual jack 6. A U-shaped groove is provided on the upper surface of the support block 7. The tension steel wire rope 5 is clamped inside the U-shaped groove. The tension of the tension steel wire rope 5 is adjusted by the manual jack 6 and the support block 7, so that the tension steel wire rope 5 applies upward tension to the wrapping template 3, so as to achieve the fit of the wrapping template 3 to the bottom of the connecting cross diaphragm 2.

[0023] An anti-friction pad 4 is provided on the outer side of the end where the tension wire rope 5 is connected to the wrapping template 3. The anti-friction pad 4 is penetrated by the tension wire rope 5 and is slidably connected to the tension wire rope 5. The anti-friction pad 4 isolates the tension wire rope 5 from the T-beam 1, preventing the tension wire rope 5 from rubbing against the T-beam 1 and causing breakage or damage.

[0024] Working principle: When pouring the connecting diaphragm 2 between two adjacent T-beams 1, firstly, the wrapping template 3 is lowered between the two T-beams 1. After the wrapping template 3 is lowered, its state is adjusted so that it is parallel to the connecting diaphragm 2. Then, the hanging plate 8, fixing plate 9, and fixing screws 10 are snapped onto the side of the T-beam 1. Next, the manual jack 6 and support block 7 are placed between the tension wire rope 5 and the T-beam 1, and the height of the support block 7 is adjusted by the manual jack 6, so that the tension wire rope 5 changes from a slack state to a relaxed state. In the taut state, the wrapping template 3 contacts the connecting transverse partition 2. Then, the inclined insert 13 is placed between the side closing template 11 and the wrapping template 3, and the inclined insert 13 is tapped downwards until the side closing template 11 is in contact with the outside of the connecting transverse partition 2. The connecting transverse partition 2 is wrapped by the wrapping template 3 and the side closing template 11. At this time, the workers can directly pour concrete between the two connecting transverse partitions 2 to form the transverse partition. Moreover, there is no need for manual operation in a suspended platform when building the template, which reduces the difficulty of template construction and improves construction efficiency.
