Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a method for constructing a star-shaped light-transmitting plain concrete wall. Background Art

[0002] The construction of translucent concrete is a construction process for public buildings that pursue the beauty of light and shadow. Its existence can enrich the appearance of the structure. At the same time, it projects light and shadow like the starry sky inside the building during the day and outside the building at night, satisfying people's pursuit of architectural beauty and a better life.

[0003] Traditional, commercially available light-transmitting concrete structures simply and directly set light-transmitting holes perpendicular to the structural surface, which greatly wastes the sunlight from the side angle of the sun and has a single arrangement. Most of the commercially available light-transmitting concrete are 20mm-30mm thick decorative panels equipped with small light sources inside, which are installed on the surface of the structure, increasing the cost of decoration and renovation while not being low-carbon and environmentally friendly.

[0004] In order to solve the above problems, a kind of fair-faced concrete wall with light guide tubes has been developed. This kind of fair-faced concrete wall structure is to pre-embed a sleeve in the fair-faced concrete wall, then cut off the two ends of the sleeve outside the wall, and finally insert the light guide tube into the sleeve and fix the light guide tube. The light guide tube is used to realize the light transmittance of the fair-faced concrete wall, and a variety of decorative patterns are realized on the surface of the fair-faced concrete wall through the light guide tube shell. However, this kind of fair-faced concrete wall still has certain problems, that is, during construction, a large number of sleeves need to be buried in the fair-faced concrete wall, and the two ends of the sleeve need to be cut to expose the two sides of the wall, resulting in a large amount of sleeve waste, and the cutting and leveling of the two ends of the sleeve is difficult, time-consuming and labor-intensive, and invisibly increases the construction cost. Summary of the invention

[0005] The purpose of the present invention is to provide a method for constructing a star-shaped light-transmitting plain concrete wall. By pre-embedding a detachable sleeve, after the wall is poured, the sleeve is removed and a light guide tube is directly installed, so that the sleeve can be reused and there is no need to cut the two ends of the sleeve, thereby reducing the construction cost and shortening the construction period.

[0006] To achieve the above object, the technical solution provided by the present invention is a method for constructing a star-shaped light-transmitting plain concrete wall, comprising the following steps:

[0007] Step 1, pre-embedded sleeve: a detachable sleeve is pre-embedded in the steel bars of the exposed concrete wall, a circle of limiting steps is arranged on the outer periphery of one end of the sleeve to form a tongue-and-groove, and the outer diameter of the end of the sleeve provided with the tongue-and-groove is the largest;

[0008] Step 2, pouring the wall: pouring the plain concrete wall;

[0009] Step 3, removing the casing: removing the casing pre-buried in the exposed concrete wall, and forming a reserved installation hole penetrating the wall in the exposed concrete wall;

[0010] Step 4, install the light guide: sleeve a waterproof rubber sleeve on the outer periphery of the light guide, the waterproof rubber sleeve covers the part of the light guide located in the wall, install the light guide sleeve with the waterproof rubber sleeve into the reserved installation hole in the wall, and seal the gap between the wall end of the light guide and the wall with transparent sealant.

[0011] Preferably, in step 1, a mold release agent is brushed on the outer periphery of the sleeve, and a water-stop rubber sleeve is provided near both ends of the outer periphery of the sleeve brushed with the mold release agent, and a steel bar positioning ring is provided on the outer periphery of the water-stop rubber sleeve, and the steel bar positioning ring is welded to the wall steel bars.

[0012] Preferably, in step 1, a release agent is brushed on the outer periphery of the sleeve, and a water-stop rubber sleeve is sleeved on the outer periphery of the sleeve brushed with the release agent, the water-stop rubber sleeve covers the entire outer periphery of the sleeve located in the wall, and steel bar positioning rings are respectively sleeved on the outer periphery of the water-stop rubber sleeve near the two ends of the sleeve, and the steel bar positioning rings are welded to the wall steel bars.

[0013] Preferably, in step 1, when the water-stop rubber sleeve covers the outer circumferential surface of the sleeve located in the wall, a plurality of ridges are arranged at intervals on the outer circumferential surface of the water-stop rubber sleeve, or the outer circumferential surface of the water-stop rubber sleeve is provided with a rough structure; when the wall is cast in step 2, the ridges or the rough structure are located in the wall concrete.

[0014] Preferably, when a plurality of ridges are arranged at intervals on the outer peripheral surface of the waterproof rubber sleeve, the ridges are annular ridges surrounding the outer periphery of the waterproof rubber sleeve, and the ridges are arranged at intervals along the length direction of the waterproof rubber sleeve.

[0015] Preferably, when the waterproof rubber sleeve covers the outer circumferential surface of the sleeve and the wall concrete fixes the waterproof rubber sleeve, after the sleeve is removed in step 3, the waterproof rubber sleeve is reserved in the installation reserved hole and is set in close contact with the installation reserved hole; when installing the light guide tube in step 4, the light guide tube is directly installed in the installation reserved hole in a manner of tightly fitting the inner wall of the installation reserved hole, and the wall end of the light guide tube and the waterproof rubber sleeve are sealed with transparent sealant.

[0016] Preferably, in step 1, when the plain concrete wall is an inclined wall, one side of the formwork should be supported first, and then the steel bars should be tied. After the wall steel bars are tied, the sleeves should be embedded in the tied wall steel bars, and then the other side of the formwork should be installed. Square timber should be set in the area where the sleeves are embedded densely to reinforce the formwork. When pouring concrete, it should be vibrated simultaneously from top to bottom to make the concrete dense.

[0017] Preferably, in step 3, the formwork is removed after the fair-faced concrete wall reaches the strength requirements of the specification, and then the sleeve is removed, and then the surface of the fair-faced concrete wall is repaired.

[0018] The embodiments of the present invention have the following beneficial effects:

[0019] The star-shaped translucent fair-faced concrete wall as the main structure can be constructed in one go, saving decoration costs.

[0020] The use of detachable sleeve embedded parts makes the sleeve reusable and adaptable to the embedding of main structures of various sizes. It also fits the light guide tube body, which helps to seal and reduce the risk of external wall leakage, while reducing construction costs and shortening construction period.

[0021] When using embedded casing, by installing a waterproof rubber sleeve covering the outer circumference of the casing, it is possible to avoid the process of rotating the casing from time to time between the initial setting and final setting of the concrete in order to facilitate the removal of the casing after pouring.

[0022] A sleeve with a tongue and groove is used so that one end of the reserved installation hole also has a tongue and groove. Correspondingly, one end of the light guide tube is also provided with a corresponding tongue and groove structure. When the light guide tube is inserted into the reserved installation hole, the tongue and groove of the light guide tube limits the position of the light guide tube, which facilitates the installation and fixation of the light guide tube.

[0031] The star-shaped light-transmitting plain concrete wall construction method of the present invention comprises the following steps:

[0032] Step 1, pre-embedded sleeve: a detachable sleeve is pre-embedded in the steel bars of the fair-faced concrete wall, a circle of limiting steps is arranged on the outer periphery of one end of the sleeve to form a tongue-and-groove, and the outer diameter of the end of the sleeve provided with the tongue-and-groove is the largest;

[0033] Step 2, pouring the wall: pouring the fair-faced concrete wall;

[0034] Step 3, removing the casing: removing the casing pre-buried in the exposed concrete wall, and forming a reserved installation hole penetrating the wall in the exposed concrete wall;

[0035] Step 4, install the light guide: sleeve a waterproof rubber sleeve on the outer periphery of the light guide, the waterproof rubber sleeve covers the part of the light guide located in the wall, install the light guide sleeve with the waterproof rubber sleeve into the reserved installation hole in the wall, and seal the gap between the wall end of the light guide and the wall with transparent sealant.

[0036] The preferred embodiments are given below and described in detail with reference to the drawings.

[0037] See also Figures 1 to 6 As shown, the star-shaped light-transmitting plain concrete wall construction method of the present invention comprises the following construction steps:

[0038] Step 1: Pre-embed the casing:

[0039] After laying the wall line, when the wall is a straight wall, tie the plain concrete wall reinforcement 2, and fix the sleeve 3 on the wall reinforcement 2 through a fixing piece at the position where the light guide 8 is required to be set on the wall reinforcement 2.

[0040] When the exposed concrete wall is a sloping wall, see Figure 1 After the wall line is placed, the plain concrete wall template 1 is supported on one side. After the position of the wall template 1 is adjusted and fixed, the plain concrete wall steel bars 2 are tied. Then, the removable sleeve 3 is embedded according to the embedded angle of the light guide obtained by the BIM simulation data. After the sleeve 3 is embedded, refer to Figure 2 , the other side of the plain concrete wall formwork 1 is supported and sealed, and wooden planks are added to reinforce the area with dense openings.

[0041] The structure of the casing 3 embedded in the wall, see Figure 3 , after pouring the concrete structure of the wall, a layer of mold release agent is applied to the surface of the sleeve 3, and waterproof rubber sleeves 6 are respectively installed on the outer circumference of the sleeve 3 near the two ends of the wall and located in the wall. The waterproof rubber sleeves 6 are in the shape of rings. A steel bar fixing ring 5 is installed on the outer circumference of the waterproof rubber sleeve 6, and the sleeve 3 with the steel bar fixing ring 5 is placed at the correct position of the wall steel bar 2, and the steel bar fixing ring 5 is welded and fixed to the steel bar 2 of the plain concrete wall to complete the pre-embedding of the sleeve.

[0042] The structure in which the sleeve 3 is embedded in the wall can also be in other forms. Figure 4 A waterproof rubber sleeve 9 is sleeved on the outer periphery of the sleeve 3. Figure 4 The waterproof rubber sleeve 9 covers the outer circumference of the sleeve 3 located in the wall. A plurality of ridges 10 or rough structures are arranged on the outer circumference of the waterproof rubber sleeve 9. The ridges 10 are preferably annular structures. Along the length direction of the waterproof rubber sleeve 9, a plurality of ridges 10 are arranged at intervals on the outer circumference of the sleeve 3. When pouring concrete, the ridges of the waterproof rubber sleeve 9 can be embedded in the wall concrete to fix the waterproof rubber sleeve 9. A steel bar fixing ring 5 is sleeved on the outer circumference of the waterproof rubber sleeve 9, and the sleeve 3 with the steel bar fixing ring 5 is placed in the correct position of the wall steel bar 2. The steel bar fixing ring 5 is welded and fixed to the steel bar 2 of the plain concrete wall to complete the pre-embedding of the sleeve 3. Figure 4 In order to facilitate demoulding, a layer of mold release agent is applied on the outer peripheral surface of the sleeve 3.

[0043] One end of the sleeve 3 is uniformly expanded outward along the circumferential direction, and a limiting step is formed on the outer periphery of one end of the sleeve 3. The expanded end of the limiting step is set as the tongue and groove of the sleeve 3, and its outer diameter is the largest.

[0044] Step 2: Casting the Wall

[0045] After the casing 3 is pre-buried, the wall concrete 4 is poured. The pouring should be carried out in layers, and the vertical upper and lower positions of the same pouring position should be vibrated and compacted at the same time. If necessary, auxiliary vibration can be performed by vibrating the lower formwork. After the concrete pouring is completed, it is covered with a film for maintenance.

[0046] Step 3: Remove the casing

[0047] The formwork can be removed only when the concrete strength reaches the demolding strength required by the specification, and then the detachable sleeve 3 is taken out from the wall. After the sleeve 3 is taken out, a reserved installation hole is left on the wall. After the sleeve 3 is taken out, the structural and color defects of the plain concrete wall are repaired.

[0048] When using step 1 Figure 3When the sleeve 3 is embedded in the structure, after the sleeve 3 is taken out, a steel bar fixing ring 5 and a waterproof rubber sleeve 6 are left in the installation reserved hole. The steel bar fixing ring 5 and the waterproof rubber sleeve 6 are both located in the wall concrete. The inner wall of the waterproof rubber sleeve 6 is flush with the inner wall of the installation reserved hole and is a part of the inner wall of the installation reserved hole. Since the outer periphery of the sleeve 3 is brushed with a release agent, it is easier to take out the sleeve 3.

[0049] When using step 1 Figure 4 When the sleeve 3 is embedded in the structure, after the sleeve 3 is taken out, the steel bar fixing ring 5 and the waterproof rubber sleeve 9 are left in the reserved hole for installation. The ridges 10 or rough structures of the steel bar fixing ring 5 and the waterproof rubber sleeve 9 are located in the wall concrete, and the inner wall of the waterproof rubber sleeve 9 is the inner wall of the reserved hole for installation. Since the outer periphery of the sleeve 3 is brushed with a release agent, it is easier to remove the sleeve 3.

[0050] When the sleeve 3 is taken out, a limiting step is formed as a tongue and groove on the inner wall of one end of the reserved hole for installation of the wall body on one side of the outer wall, so that the inner diameter of the inner wall of the reserved hole for installation at one end where the limiting step is set is the largest.

[0051] Step 4: Install the light guide

[0052] The light guide tube 8 is an acrylic light guide tube.

[0053] When Figure 3 When the sleeve is embedded in the way, after the sleeve 3 is taken out, the inner wall of the reserved hole for installation is mostly wall concrete. When installing the light guide 8, refer to Figure 5 , along the length direction of the light guide tube 8, a waterproof rubber sleeve 9 is sleeved on the outer peripheral surface of the light guide tube 8 located in the exposed concrete wall, and the waterproof rubber sleeve 9 covers the outer peripheral surface of the light guide tube 8 located in the wall. Then the light guide tube 8 sleeved with the waterproof rubber sleeve is inserted into the reserved installation hole, so that the waterproof rubber sleeve fits tightly with the inner wall of the reserved installation hole, and a transparent silicone sealant 7 is injected into the gap between the outer end of the light guide tube 8, the waterproof rubber sleeve and the exposed concrete wall 4 to seal and prevent the risk of leakage from the external wall.

[0054] by Figure 3 In the pre-embedded method, when installing the light guide tube, a waterproof rubber sleeve is put on the outer circumference of the light guide tube. Therefore, when the light guide tube is installed, the waterproof rubber sleeve will stick to the inner wall of the reserved hole for installation due to its certain elasticity. During the insertion process of the light guide tube, the friction between the waterproof rubber sleeve and the inner wall of the reserved hole for installation is increased, making the installation more time-consuming.

[0055] When Figure 4 When the sleeve is embedded in the way, after the sleeve 3 is taken out, the inner wall of the reserved hole is all waterproof rubber sleeve 9. Therefore, when installing the light guide 8, refer to Figure 6, directly insert the light guide 8 into the reserved installation hole, so that the light guide 8 fits tightly with the inner wall of the waterproof rubber sleeve 9, and finally inject transparent silicone sealant 7 into the gap between the outer end of the light guide 8, the waterproof rubber sleeve and the exposed concrete wall 4 to seal and prevent the risk of leakage from the outer wall. In this way, when installing the light guide, it is not necessary to set a waterproof rubber sleeve on its outer circumference. Since the outer circumference of the light guide is smooth, the installation is relatively convenient and quick.

[0056] One end of the light guide 8 has the same structure as the tongue-and-groove structure at one end of the reserved hole for installation. When the light guide 8 is installed, it is installed from the wall surface on the side with the tongue-and-groove. In this installation method, during the installation process, the limit step of the tongue-and-groove of the reserved hole for installation will limit the position of the light guide to ensure that it is installed in place.
