Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, and particularly relates to a flow-blocking device for concrete pouring on a pitched roof. Background Technique

[0002] In the prior art, due to construction conditions during the concrete pouring on a pitched roof, the concrete can only be naturally formed in a sliding state without restraint on the slope surface. It is difficult to control the compactness of the concrete pouring, and the construction quality is difficult to achieve the expected effect. Moreover, during vibration, it is also easy to cause phenomena such as flowing and sliding, and segregation, leaving common problems of leakage hidden dangers in the construction of the concrete structure.

[0003] In addition, compared with the construction of a horizontal structural slab, the in-situ concrete pouring on a pitched roof cannot effectively control the flatness and slab thickness of the in-situ concrete slab through an infrared level, thus affecting the cross-sectional dimensions and appearance quality of the pitched roof slab (5). Controlling the thickness and flatness of the concrete roof slab is a construction difficulty. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a flow-blocking device for concrete pouring on a pitched roof.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flow-blocking device for concrete pouring on a pitched roof includes a flow-blocking component. The flow-blocking component includes support ribs, web bars, and elevation components. Web bars are arranged on both sides of the support ribs. The bottom of the support ribs is connected to the bottom steel mesh of the pitched roof, and the top of the support ribs is connected to the top steel mesh of the pitched roof. Elevation components are arranged on the support ribs. The bottom steel mesh of the pitched roof is arranged on the upper surface of the pitched roof slab. The upper and lower vertices of the support ribs are respectively welded or tied to the top steel mesh and the bottom steel mesh of the pitched roof. The web bars are welded or tied to the support ribs. The web bars mainly play a role in strengthening the flow-blocking and improving the structural rigidity of the flow-blocking device.

[0006] Further, the shape of the support ribs is "U", and the number of the web bars is four. The four web bars are symmetrically arranged on both sides of the support ribs.

[0007] Further, the elevation component includes an elevation rod, connection buckles, and elevation rings. The number of the connection buckles is two. One of the connection buckles is fixedly connected to the bottom of the elevation rod, and the other connection buckle is movably arranged in the middle of the elevation rod. The elevation device is connected to the bottom steel mesh of the pitched roof through the connection buckle at the bottom, and the elevation rod is connected to the top of the support ribs through the connection buckle in the middle.

[0008] Further, scale lines are engraved on the elevation rod, and elevation rings are sleeved on the elevation rod. The elevation rings are of bright colors such as red or yellow, so as to facilitate construction workers to observe the concrete pouring situation and effectively control the thickness of the in-situ slab.

[0009] Furthermore, the connecting buckle includes a buckle base and a buckle cover. The buckle base has a buckle groove, and the buckle cover has a buckle strip. The buckle groove and the buckle strip are compatible with each other.

[0010] Furthermore, both the bottom steel mesh and the top steel mesh of the sloping roof are formed by cross-weave binding.

[0011] Beneficial effects:

[0012] Compared with existing technologies, this type of concrete pouring obstruction device for sloping roofs has the following beneficial effects:

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown in the figure, the utility model provides a technical solution: a flow-blocking device for concrete pouring on a sloping roof includes a flow-blocking component 1. The flow-blocking component 1 includes a support rib 101, web reinforcement 102, and an elevation component 2. Web reinforcement 102 is arranged on both sides of the support rib 101. The bottom of the support rib 101 is connected to the bottom steel mesh 3 of the sloping roof, and the top of the support rib 101 is connected to the top steel mesh 4 of the sloping roof. An elevation component 2 is arranged on the support rib 101. The bottom steel mesh 3 of the sloping roof is arranged on the upper surface of the sloping roof panel 5. The upper and lower vertices of the support rib 101 are respectively welded or tied to the top steel mesh 4 and the bottom steel mesh 3 of the sloping roof. The web reinforcement 102 is welded or tied to the support rib 101. The web reinforcement 102 mainly plays a role in strengthening the flow-blocking effect and improving the structural rigidity of the flow-blocking device.

[0021] The shape of the support rib 101 is "U"-shaped. The number of the web reinforcement 102 is four, and the four web reinforcement 102 are symmetrically arranged on both sides of the support rib 101.

[0022] The elevation component 2 includes an elevation rod 201, a connection buckle 202, and an elevation ring 203. The number of the connection buckles 202 is two. One of the connection buckles 202 is fixedly connected to the bottom of the elevation rod 201, and the other connection buckle 202 is movably arranged in the middle of the elevation rod 201. The elevation device is connected to the bottom steel mesh 3 of the sloping roof through the connection buckle 202 at the bottom, and the elevation rod 201 is connected to the top of the support rib 101 through the connection buckle 202 in the middle.

[0023] Scale lines are engraved on the elevation rod 201. An elevation ring 203 is sleeved on the elevation rod 201. The elevation ring 203 is in bright colors such as red or yellow, so as to facilitate construction workers to observe the concrete pouring situation and effectively control the thickness of the cast-in-place slab.

[0024] The connection buckle 202 includes a buckle base 204 and a buckle cover 205. A buckle groove 207 is formed on the buckle base 204, and a buckle strip 206 is arranged on the buckle cover 205. The buckle groove 207 and the buckle strip 206 are adapted to each other.

[0025] Both the bottom steel mesh 3 and the top steel mesh 4 of the sloping roof are bundled in a crosswise manner of warp and weft.

[0026] The operation steps of this device are as follows:

[0027] (1) First, formwork is erected on the sloping roof, the surface of the formwork is cleaned, and the distribution spacing lines of the bottom steel bars of the sloping roof are marked on the formwork using a chalk line, and then the bottom steel mesh 3 of the sloping roof is tied up.

[0028] (2) Fix the web reinforcement 102 to the supporting reinforcement 101. The spacing of the web reinforcement 102 is generally 100 mm, and the quantity is determined according to the thickness of the inclined roof slab. The "U-shaped" supporting reinforcement 101 is generally distributed at an equal spacing of 500 mm, and the flow-blocking component 1 is fabricated;

[0029] (3) Fix the fabricated flow-blocking component 1 to the bottom steel mesh 3 of the inclined roof. The flow-blocking component 1 is arranged parallel to the ridge direction, generally at an equal spacing of 1200 mm, and the length is determined according to the length of the ridge. When the length is insufficient, several flow-blocking components 1 can be butt-jointed and tied with butt-joint steel bars to achieve lengthening;

[0030] (4) Select appropriate positions on each flow-blocking component 1 to arrange the elevation component 2. The bottom of the elevation component 2 is fixed to the bottom steel mesh 3 of the inclined roof through the connecting buckle 202, and the top is fixed to the supporting reinforcement 101 through the connecting buckle 202;

[0031] (5) After the top steel mesh 4 of the inclined roof is constructed and tied, fix the top of the flow-blocking component 1 to the top steel mesh 4 of the inclined roof. At this time, the flow-blocking component 1 also functions as a supporting bar;

[0032] (6) Pour the concrete. When pouring the concrete, the concrete shall not be concentrated and stacked, but should be poured in layers and symmetrically; protective measures shall be taken below the working layer; when pouring the concrete, no one shall stand under the support. The concrete vibration is carried out by inclined-layer vibration, vibrating quickly and pulling out slowly, starting from the bottom layer of the pouring layer and gradually moving up to ensure the construction quality between the layered concretes. The vibration time for each time is preferably 20 - 30 s (based on the fact that no bubbles appear on the concrete surface and the mortar is oozing out). The concrete pouring of the inclined roof shall start from the eaves and be constructed from the bottom to the ridge, and with the highest ridge line as the symmetry axis, pour symmetrically and alternately on both sides (the pouring width is about 2 meters), and the interval time shall be less than the initial setting time of the concrete (within 3 hours). During the concrete pouring process, the inclined roof project is a key part, and full-time personnel shall be arranged to frequently observe the conditions of the formwork, support, steel bars, etc. When deformation or movement is found, corresponding measures shall be taken in a timely manner. Because the roof is an inclined roof and it is difficult to form the concrete, the concrete slump is required to be 100 - 120 mm, and the concrete is poured in two layers. For the first layer, pour step by step from the bottom to the top in a stepped manner, vibrating while pouring on each step. Due to the flow-blocking effect of the flow-blocking device, the concrete presents a stepped shape; the second layer is poured before the first-layer stepped concrete begins to set, also pouring step by step from the bottom to the top and vibrating while pouring. After the second-layer concrete is poured, the concrete forms a stable inclined-plane state on the slope and will not show the phenomenon of sliding down. The flow-blocking device has a good flow-blocking effect on the inclined roof concrete, ensuring that the concrete reaches a dense effect after pouring and forming;

[0033] (7) The elevation component 2 is installed before the concrete is poured. Specifically, the elevation measurement personnel shall measure and mark the finished concrete surface elevation at each internal and external corner position and the position in the middle of the slab. With the cooperation of the steelworkers, the elevation ring 203 shall be used to clearly mark the elevation on the elevation rod 201. The height mark of the elevation ring 203 is the finished concrete surface elevation.

[0034] In summary, this device can effectively assist construction workers in improving the density of concrete during the concrete pouring process, effectively prevent concrete from falling and sliding down the slope during pouring, prevent the flow, slippage, and segregation of concrete during vibration of sloping roofs, effectively control the flatness of the cast-in-place slab surface, and effectively control the thickness of the cast-in-place slab by setting an elevation device.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
