Description

Technical Field

[0001] This application relates to the field of construction auxiliary devices, and in particular to a temporary passage structure that crosses a post-cast strip. Background Technology

[0002] When constructing large-area building floors, multiple concrete slabs need to be poured on the ground. Temporary construction joints are set between the concrete slabs to overcome harmful cracks caused by temperature and shrinkage. Post-pouring strips refer to the process of pouring cement mortar into the temporary construction joints to connect multiple concrete slabs into a whole.

[0003] To facilitate the handling of building materials and construction between concrete slabs, temporary passageways are usually set up between adjacent concrete slabs. These temporary passageways are made of wooden planks or metal sheets and are placed over the two concrete slabs to facilitate the movement of construction workers and loading tools between them.

[0004] The aforementioned technical solutions have the following drawbacks: when the load on the loading tool is large, the stress applied to the temporary channel is large, and when the structural strength of the temporary channel is poor, it is easy to deform or break, causing safety accidents and affecting the pouring quality of the post-pouring strip. Utility Model Content

[0005] To improve the structural strength of temporary passages, this application provides a temporary passage structure that spans post-cast strips.

[0006] The technical solution for a temporary channel structure spanning a post-cast strip provided in this application is as follows:

[0007] A temporary passage structure spanning a post-cast strip includes a three-section steel plate, multiple I-beams, supporting members, and a bottom steel plate. The bottom steel plate is horizontally placed on two concrete base plates. The supporting members are placed in the gap between the concrete base plates and are used to support the bottom steel plate. Multiple I-beams are fixed on the bottom steel plate, with both ends of the I-beams located on the two concrete base plates respectively. The three-section steel plate is placed on the top surface of the I-beams.

[0008] By adopting the above technical solution, a support component is installed at the bottom of the bottom steel plate, which supports the bottom steel plate in the gap between the two concrete base slabs. The bottom steel plate covers the space between the two concrete base slabs, allowing personnel and loading tools to move on the bottom steel plate and facilitating movement between the two concrete base slabs. An I-beam is installed on the bottom steel plate to further enhance the structural strength of the temporary passage. Three-section steel plates are installed on the I-beam, covering the I-beam and making the upper surface of the temporary passage flat. The I-beam supporting the three-section steel plates provides better structural strength for the temporary passage and facilitates the movement of heavy-load loading tools between the two concrete base slabs.

[0009] Optionally, side sealing plates are provided on both sides of the bottom steel plate, and the side sealing plates, the three-section steel plate and the bottom steel plate are assembled together to form a closed box structure.

[0010] By adopting the above technical solution and setting side sealing plates on the bottom steel plate, when cement mortar is poured between two concrete bottom plates, the probability of cement mortar overflowing and accumulating on the bottom steel plate can be reduced, making it easier to clean the temporary passage.

[0011] Optionally, the three-section steel plate includes a horizontal section and two inclined sections, with the two inclined sections respectively located on both sides of the horizontal section. The three-section steel plate is formed by bending to create the horizontal section and the inclined sections, which are then welded and fixed to the bottom steel plate.

[0012] By adopting the above technical solution, by bending the steel plate to form a horizontal part and an inclined part, the loading tool on the concrete base plate can be moved from the inclined part to the horizontal part, making it convenient for users to push the handcart between the two concrete base plates.

[0013] Optionally, the I-beam has inclined surfaces at both ends, and the inclined surfaces abut against the inclined portion.

[0014] By adopting the above technical solution, by opening an inclined surface at the end of the I-beam, the inclined surface can be locked on one side of the inclined part, thereby providing support for the horizontal and inclined parts of the I-beam and reducing the probability of deformation of the temporary passage.

[0015] Optionally, an anti-slip layer is provided on the surface of the bottom steel plate away from the I-beam. The anti-slip layer is made of a rough-surfaced rubber material and is used to abut against the concrete base plate.

[0016] By adopting the above technical solution, and by setting an anti-slip layer on the bottom steel plate, when the bottom steel plate is placed on the concrete base plate, the anti-slip layer contacts the top surface of the concrete base plate, thereby increasing the friction between the bottom steel plate and the concrete base plate, reducing the probability of the bottom steel plate sliding on the concrete base plate, and improving the positional stability of the bottom steel plate.

[0017] Optionally, the support member is configured as a limiter, which is welded and fixed to the bottom steel plate.

[0018] By adopting the above technical solution, by welding a limiter onto the bottom steel plate, the limiter can be locked between the two concrete base plates, so that when the bottom steel plate slides, it can always cover the gap between the two concrete base plates, reducing the chance of users stepping into the gap between the concrete base plates and damaging the cast-in-place structure when moving.

[0019] Optionally, the support member is configured as a reinforcing cage, which is placed in the gap between two concrete base slabs. The reinforcing cage is used to be mixed into the cement mortar and together form the post-cast strip.

[0020] By adopting the above technical solution, a steel cage is set between two concrete base slabs, allowing cement mortar to submerge the steel cage and form a reinforced concrete structure, thereby improving the structural strength of the post-cast strip.

[0021] Optionally, the reinforcing cage includes multiple horizontal reinforcing bars. One end of each horizontal reinforcing bar is fixed with an abutment seat, and the other end is threaded with a sleeve. A rubber block is provided at the end of the sleeve. The rubber block and the abutment seat are made of rubber material and abut against the side wall of the concrete base, respectively.

[0022] By adopting the above technical solution, by setting abutment seats and sleeves at both ends of the horizontal reinforcing bars, the user can rotate the sleeve to make the rubber block on the sleeve abut against the side wall of the concrete base slab, thereby keeping the reinforcing cage in a stable position in the gap between the concrete base slabs. By screwing the sleeve, the end of the sleeve can move, so that the reinforcing cage can be stuck between the two concrete base slabs after being placed in the gap, reducing the chance of the reinforcing cage scratching the concrete base slab.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By installing support components at the bottom of the bottom steel plate, the support components can support the bottom steel plate in the gap between the two concrete bottom slabs. The bottom steel plate covers the space between the two concrete bottom slabs, allowing personnel and loading tools to move on the bottom steel plate, facilitating movement between the two concrete bottom slabs. By installing I-beams on the bottom steel plate, the structural strength of the temporary passage is further enhanced. By installing three-section steel plates on the I-beams, the upper surface of the temporary passage is made flat. The I-beams supporting the three-section steel plates provide better structural strength for the temporary passage, facilitating the movement of heavy-load loading tools between the two concrete bottom slabs.

[0025] 2. By bending the steel plate to form a horizontal and an inclined section, the loading tools on the concrete base plate can be moved from the inclined section to the horizontal section, making it convenient for users to push the handcart between the two concrete base plates;

[0026] 3. By setting abutment seats and sleeves at both ends of the horizontal reinforcing bars, the user can rotate the sleeve to make the rubber block on the sleeve abut against the side wall of the concrete base slab, thereby keeping the reinforcing cage in a stable position in the gap between the concrete base slabs. By screwing the sleeve, the end of the sleeve can move, so that the reinforcing cage can be stuck between the two concrete base slabs after being placed in the gap, reducing the chance of the reinforcing cage scratching the concrete base slab.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a temporary channel structure that spans a post-cast strip, referring to... Figure 1 and Figure 2 The system comprises a three-section steel plate 1, multiple I-beams 2, supporting members, and a bottom steel plate 4. Multiple concrete base slabs are poured on the ground, forming gaps between them. The supporting members are positioned between these gaps. The bottom steel plate 4 is laid horizontally on the concrete base slabs. The supporting members are connected to the bottom steel plate 4 and are used to support it. The supporting members can be secured between two concrete base slabs, thereby reducing the likelihood of slippage and improving stability when walking on it. Multiple I-beams 2 are installed on the bottom steel plate 4, parallel to each other and parallel to the width direction of the bottom steel plate 4. The I-beams 2 are arranged at equal intervals along the length direction of the bottom steel plate 4. When the bottom steel plate 4 is placed on two concrete base slabs, the two ends of the I-beams 2 are respectively positioned on the concrete base slabs. A three-section steel plate 1 is installed on the I-beam 2. The three-section steel plate 1 includes a horizontal section 11 and two inclined sections 12. The two inclined sections 12 are respectively located on opposite sides of the horizontal section 11. The three-section steel plate 1 is formed by bending steel plates to form the horizontal section 11 and the inclined sections 12. When the three-section steel plate 1 is installed on the I-beam 2, the horizontal section 11 covers the top surface of the I-beam 2, and the edges of the inclined sections 12 are welded and fixed to the bottom steel plate 4. Users can push loading tools such as handcarts across the inclined sections 12, allowing the loading tools to move between the two concrete base plates. Construction workers can pour cement mortar between two adjacent concrete base plates, and can walk between the concrete base plates before the cement mortar hardens, improving work efficiency.

[0035] Reference Figure 2 The I-beam 2 has inclined surfaces 21 at both ends, which abut against the inclined part 12. When the three-section steel plate 1 is placed on the I-beam 2, the I-beam 2 can provide support for the horizontal part 11 and the inclined part 12, thereby improving the structural strength of the temporary passage.

[0036] Reference Figure 2 The support component is set as a limiter 3, which is a metal strip structure. The limiter 3 is welded and fixed to the bottom steel plate 4. When the bottom steel plate 4 is placed on the two concrete base plates, the limiter 3 is stuck between the concrete base plates and supports the bottom steel plate 4, so that the temporary passage remains in a stable position.

[0037] Reference Figure 3 Anti-slip layers 41 are provided on both sides of the bottom steel plate 4. The anti-slip layers 41 are made of a rough-surfaced rubber material and are bonded and fixed to the surface of the bottom steel plate 4 away from the I-beam 2. When the bottom steel plate 4 is placed on the concrete base plate, the anti-slip layers 41 come into contact with the concrete base plate, thereby further increasing the friction between the bottom steel plate 4 and the concrete base plate and reducing the probability of the bottom steel plate 4 slipping.

[0038] Reference Figure 2 Side sealing plates 5 are provided on both sides along the length of the three-section steel plate 1. The side sealing plates 5 are isosceles trapezoidal plate structures. The upper bottom of the side sealing plate 5 is welded to the horizontal part 11, the waist of the side sealing plate 5 is welded and fixed to the inclined part 12, and the lower bottom of the side sealing plate 5 is welded to the bottom steel plate 4. The side sealing plates 5 are placed on the ends of the bottom steel plate 4, which can reduce the probability of cement mortar accumulating on the upper surface of the bottom steel plate 4 when pouring cement mortar.

[0039] Reference Figure 4 In other embodiments, the support is a reinforcing cage 6, which is formed by splicing reinforcing bars. The reinforcing cage 6 is placed in the gap between two concrete base slabs, and its height is flush with the concrete base slabs. A bottom steel plate 4 is placed on the reinforcing cage 6, and the reinforcing cage 6 serves to support the bottom steel plate 4. When cement mortar is poured between two adjacent concrete base slabs, the cement mortar submerges the reinforcing cage 6, so that after the cement mortar solidifies, it forms a reinforced concrete structure with the reinforcing cage 6, which can improve the structural strength of the post-cast strip.

[0040] Reference Figure 5 The steel cage 6 is provided with multiple horizontal steel bars. The length direction of the horizontal steel bars is perpendicular to the side wall of the concrete base slab. The ends of the horizontal steel bars are provided with abutment seats 61. The abutment seats 61 are made of rubber material and are used to abut against the side wall of the concrete base slab, thereby reducing the probability of the horizontal steel bars abrading the side wall of the concrete base slab and keeping the concrete base slab with high structural strength.

[0041] Reference Figure 5A sleeve 62 is provided on the end of the horizontal reinforcing bar away from the abutment seat 61. The sleeve 62 is fitted onto the end of the horizontal reinforcing bar and is threadedly connected to the horizontal reinforcing bar. A rubber block 621 is provided on the end of the sleeve 62 away from the horizontal reinforcing bar, and the rubber block 621 is used to abut against the concrete base slab. By rotating the sleeve 62, the user can move the sleeve 62 on the horizontal reinforcing bar, thereby causing the abutment seat 61 and the rubber block 621 to abut against the two side walls of the concrete base slab respectively, thus keeping the reinforcing cage 6 fixed in the gap between the two concrete bases.

[0042] The implementation principle of this application embodiment is as follows: A bottom steel plate 4 is set on a concrete base plate, and an I-beam 2 is set on the bottom steel plate 4. The two ends of the I-beam 2 are respectively set on two concrete base plates. A three-section steel plate 1 is covered on the I-beam 2, allowing users to walk on the three-section steel plate 1, which facilitates the pouring of cement mortar between the two concrete base plates. By bending the three-section steel plate 1 to form an inclined part 12, an inclined surface is formed between the horizontal part 11 and the upper surface of the concrete base plate, which facilitates the movement of loading tools between the two concrete base plates and improves construction efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
