Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a water bag box mold. Background Art

[0002] With the increase in population, people have an increasing demand for large-space personalization and high-rise buildings. The commonly used beamless solid floor slabs use a large amount of concrete, which results in the heavy load-bearing columns to be evenly arranged. For multi-story and high-rise buildings with large spans and loads and large spaces, their structural economy is greatly limited.

[0003] In order to retain the large span and clear height of each floor and reduce the deadweight of the structure, dense ribbed floor is often used nowadays. The construction of dense ribbed floor requires the use of box formwork to form cavities between the dense ribs to reduce the deadweight of the structure. The box formwork is often made of fixed hard materials, which is not easy to remove after the concrete is poured. It is also easy to damage the box formwork and the edges and corners of the structure when prying with tools such as crowbars. At the same time, the box formwork is light and is easy to float when the concrete is poured. Utility Model Content

[0033] Example 1

[0034] refer to Figures 1 to 3 As shown, a water bag box mold 10 is shown in the figure. The water bag box mold 10 is a cavity-shaped structure, including: an outer mold 101, a water injection port 105, a drainage port 106 and a support member arranged in the water bag box mold 10.

[0035] The outer mold 101 is made of a wear-resistant and puncture-resistant flexible material, and when the water bag box mold 10 is filled with a medium, the cross-section of the outer mold 101 is an isosceles trapezoidal structure. The top of the outer mold 101 is provided with a water injection port 105 for injecting medium water into the water bag box mold 10; the bottom of the outer mold 101 is provided with a drain port 106 for draining the medium inside the water bag box mold 10.

[0036] After the water bag box mold 10 is filled with water, it has enough weight. During the concrete pouring process, the water bag box mold 10 will not float up. At the same time, it can reduce the accumulation of concrete hydration heat and reduce the risk of concrete cracking and water seepage.

[0037] Preferably, the support member includes corner braces 102 , and each corner brace 102 is respectively arranged at each corner position in the cavity of the water bag box mold 10 .

[0038] Preferably, the support member includes a folding waist support 103, and the folding waist support 103 is arranged at waist positions on both sides of the cavity of the water bag box mold 10, and the folding waist support 103 can be folded.

[0039] Preferably, the support member includes a vertical support 104, and the vertical support 104 is an X-shaped structure, which is used to complete the vertical support of the cavity of the water bag box mold 10.

[0040] Preferably, the two supporting points where the vertical support 104 connects with the top of the outer mold 101 are respectively located on both sides of the water injection port 105; the two supporting points where the vertical support 104 connects with the bottom of the outer mold 101 are respectively located on both sides of the drainage port.

[0041] The corner supports, folding waist supports and vertical supports are arranged in the water bag box mold 10 so that after the water bag box mold 10 is opened, the contact surfaces with concrete are subjected to stable force and the quality of concrete corner molding is guaranteed. The folding waist supports can also ensure that the outer membrane of the water bag is easy to fold and store.

[0042] Preferably, a first plug body 107 is provided at the water injection port 105, and a first sealing gasket 108 is provided between the first plug body 107 and the crimping surface of the outer mold 101. The first sealing gasket 108 is provided at the water injection port to ensure that the first plug body 107 does not leak when it is plugged tightly.

[0043] Preferably, a second plug is provided at the drain port 106 to discharge the medium in the cavity.

[0044] Preferably, the second plug body can be a push plug, and an annular drain pipe 206 is provided on the outside of the push plug, and drainage holes are respectively provided on the plug wall 207 of the push plug and the wall of the drain pipe 206. When the drainage holes on the plug wall 207 and the drainage holes on the wall of the drain pipe 206 coincide with each other, the medium inside the water bag box mold 10 is discharged through the drain pipe 206 and the push plug.

[0045] The push plug is closed when pressed, and water flows out when opened. A second sealing gasket 203 is provided at the position of the push plug cover plate 202, which slides up and down through the spring 205 in the sealing tube core 204. The push plug slides on the wall of the drain pipe 206, and the drain holes are staggered on the drain pipe 206 and the plug wall 207 of the push plug. When the push plug is pressed, the drain holes on the two pipe walls are staggered, so that the water in the cavity of the water bag box mold 10 no longer flows into the drain pipe 206, avoiding water leakage due to the poor clogging of the push plug; when the push plug is pressed, the drain holes on the two pipe walls overlap to drain water.

[0046] When pouring the multi-rib beam 30, medium water is input into the cavity of the water bag box mold 10 and is evenly spaced on the pouring template 50 of the multi-rib beam 30. The pouring template 50 is provided with a notch at the position of the drain port 106 of the water bag box mold 10 to facilitate the later discharge of medium water in the water bag box mold 10.

[0047] like Figure 4 As shown, during the pouring construction of the multi-rib beam 30, a support frame 60 is set up according to the design scheme, and a pouring template 50 (not fully laid) is laid out on both sides of the pouring position of the multi-rib beam 30 for a certain length. After the pouring template 50 is installed, the positions of the multi-rib beam 30 and the water bag box mold 10 are laid out according to the design drawings, and the water bag box mold 10 is placed on the two pouring templates 50, and the lower water outlet is not blocked by the template.

[0048] After the water bag box mold 10 is placed, water is injected into the cavity through the water injection port 105. When the water injection is completed and the corner braces, waist braces and cross braces are all opened to the required degree, the first plug body 107 is screwed into the water injection port position. Before pouring concrete, the position of the water bag box mold 10 is checked and adjusted if there is any deviation in the position.

[0049] Tie up the dense rib beam and the floor steel bar 301, and pour the concrete. After the concrete pouring is completed and reaches the design demoulding strength requirement, connect the drainage pipe at the drainage port 106 to drain the water, collect the water in the cavity of the water bag box mold 10 for secondary use; finally, remove the support frame and the template, take out the water bag box mold and reuse it.

[0050] The structural setting of the water bag box mold of the utility model solves the problem that the traditional box mold is prone to floating up during the concrete pouring process and cannot be reused.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
