Description

Technical Field

[0001] This application relates to the field of sloping roof pouring construction technology, specifically a sloping roof concrete pouring construction structure. Background Technology

[0002] Sloping roof structures are increasingly used in modern architecture. This type of roof can provide a variety of roof shapes, and the staggered sloping roofs can also bring people a novel, unique and diverse architectural beauty.

[0003] For ultra-sloping roofs with a design slope between 30° and 60°, the formwork is mostly used for formwork support and then pouring concrete. However, if a single-layer bottom formwork is installed, the slope is too steep and it cannot be vibrated to form the desired shape. If a double-layer formwork is installed, it is very difficult to insert a vibrator and the quality is hard to guarantee. If a layer of wire mesh is added on the surface of the reinforcing steel for pouring and compaction, the steep slope often causes the concrete to slip and crack during the vibration process, resulting in poor quality of the poured concrete for the steep roof. Utility Model Content

[0004] In view of the problem of low quality in the casting and molding of steep sloping roofs in the existing technology, this utility model provides a construction structure for casting concrete for sloping roofs.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: This utility model provides a construction structure for pouring concrete on a sloping roof, characterized by: including... The support frame has a support base plate at its top, and a bottom formwork is installed on top of the support base plate. Side ribs are installed at both ends of the top of the support frame in the horizontal direction. A top formwork is installed above the bottom formwork. There are multiple sets of top formwork, which are arranged at intervals along the inclination direction of the support base plate. A movable formwork is installed between two adjacent sets of top formwork. The bottom formwork, side ribs, top formwork and movable formwork form a casting cavity. A steel mesh is installed in the casting cavity. A support top plate is installed on top of the top formwork. Water-stop bolts are installed between the top formwork and the bottom formwork.

[0006] Preferably, the casting cavity is provided with a support, and the support is arranged in multiple sets at intervals along the inclined direction, with the bottom of the support welded to the steel mesh.

[0007] Preferably, the upper and lower ends of the movable template each abut against a set of top templates, and the abutment points of the movable template and the top templates are glued and fixed.

[0008] Preferably, the support frame is provided with diagonal braces and scissor braces.

[0009] Preferably, the supporting base plate is tied to the supporting frame with lead wire.

[0010] Preferably, the top template, bottom template, and movable template are all coated with a release agent on the side closest to the pouring cavity.

[0011] Preferably, the water-stop bolt is welded to the reinforcing mesh.

[0012] The advantages of adopting the above technical solution are: This invention includes a top template, which is arranged in multiple sets along the inclined direction of the supporting base plate. A movable template is installed between adjacent sets of top templates. A supporting top plate is installed on the top of the top template. Water-stop bolts are installed between the top template and the bottom template. After the bottom template, top template, and side ribs are laid, workers pour concrete into the pouring cavity from bottom to top along the inclined direction of the eaves, through the gaps between adjacent sets of top templates. After pouring and vibration, the gaps are sealed by the movable template. Then, the pouring and movable template laying are repeated in the gaps between every two sets of top templates above, realizing the step-by-step pouring of the roof from bottom to top, reducing concrete slippage and ensuring the quality of concrete pouring.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1-3As shown in the figure, this utility model embodiment discloses a concrete pouring construction structure for a sloping roof, including a support frame 1, a support base plate 2 inclinedly arranged on the top of the support frame 1, a bottom template 3 arranged on the top of the support base plate 2, side ribs arranged at both ends of the top of the support frame 1 along the horizontal direction, a top template 5 arranged above the bottom template 3, the number of top templates 5 being multiple sets and arranged at intervals along the inclined direction of the support base plate 2, a movable template 51 arranged between two adjacent sets of top templates 5, a pouring cavity 50 formed by the bottom template 3, side ribs, top template 5 and movable template 51, a steel mesh arranged in the pouring cavity 50, a support top plate 6 arranged on the top of the top template 5, and a water-stop bolt 4 passing through the top template 5 and the bottom template 3.

[0018] In at least one embodiment, a support 7 is provided inside the pouring cavity 50. The support 7 is in multiple sets and is arranged at intervals along the inclined direction. The bottom of the support 7 is welded to the steel mesh. The support 7 is in the shape of a steel bar. The length of the support 7 is the same as the thickness of the concrete pouring. The two ends of the support 7 abut against the top formwork 5 and the bottom formwork 3 respectively, thereby supporting them and ensuring the thickness of the concrete pouring. Furthermore, the welding of the support 7 to the steel mesh ensures the stability of the support 7 and prevents the support 7 from shifting.

[0019] In at least one embodiment, the upper and lower ends of the movable template 51 abut against a set of top templates 5 respectively. The abutment of the movable template 51 and the top template 5 is bonded and fixed. After the movable template 51 abuts against the top template 5, the gap between the two sets of top templates 5 is sealed, thereby facilitating the subsequent pouring operation above. The joint of the movable template 51, the top template 5 and the bottom template 3 is planed and then pasted with double-sided foam tape to ensure the sealing of the joint and avoid grout leakage.

[0020] In at least one embodiment, the support frame 1 is provided with diagonal braces and scissor braces to provide auxiliary support for the support frame 1 and prevent the frame of the support frame 1 from becoming unstable.

[0021] In at least one embodiment, the support base plate 2 is tied to the support frame 1 with lead wire, and the support base plate 2 is tied at multiple points along the length direction. The distance between two adjacent sets of tying points is no more than 1000mm, thereby fixing the support base plate 2 to the support frame 1 and ensuring the stability of the support base plate 2.

[0022] In at least one embodiment, the top template 5, the bottom template 3, and the movable template 51 are all coated with a release agent on the side near the casting cavity 50.

[0023] In at least one embodiment, the water-stop bolt 4 is welded to the reinforcing mesh. By welding the water-stop bolt 4 to the reinforcing mesh, the reinforcing mesh is further limited and fixed, reducing the bending of the reinforcing mesh on the sloping roof and ensuring the quality of the roof pouring.

[0024] In at least one embodiment, scaffold boards 100 are laid on the support frame 1, and a mobile platform is laid on the support frame 1 through the scaffold boards 100, so that workers can carry out mobile operations on the mobile platform.

[0025] When pouring concrete for a steeply sloping roof, the workers first erect a support frame 1 below the roof to be poured. Support frame 1 is a full-span scaffold formed by vertically and horizontally splicing multiple sets of steel pipes. Before erecting support frame 1, the beam edge lines, ridge lines, and corner lines of the sloping roof (the horizontal projection lines of the entire sloping roof) are pre-marked on the building floors. During erection, the vertical and horizontal steel pipes at the high and low points are erected according to the control elevation. After support frame 1 is erected, the main joists are laid on top of it. The main joists use multiple sets of double steel pipes evenly spaced. Then, multiple sets of support base plates 2 are laid on top of the main joists along the sloping direction. Both the main joists and the support base plates 2 are tied and fixed to the steel pipes in support frame 1 with wire to ensure stability. To ensure the stability of the supporting base plate 2, multiple sets of bottom formwork 3 are then laid on top of the supporting base plate 2 along the inclined direction from the lowest point of the eaves to the highest point. The joints between adjacent sets of bottom formwork 3 are located on the supporting base plate 2 to prevent subsequent grout leakage. The bottom formwork 3 is fixed to the supporting base plate 2 with nail guns or screws. Then, the side ribs are fixed to both sides and the bottom of the eaves in the horizontal direction and fixed to the supporting base plate 2 with nail guns or screws using short wooden blocks. Both the bottom formwork 3 and the top formwork 5 are pre-drilled with holes for matching the water-stop bolts 4. After the bottom formwork 3 is laid, the steel mesh is placed on the bottom formwork 3. Then, the water-stop bolts 4 are arranged at intervals on the bottom formwork 3, with one end passing through the drilled hole in the bottom formwork 3 and connected to the double steel pipe at the bottom using a U-shaped clamp. After the main keel is fixed by clamping, multiple sets of top formwork 5 are laid evenly at intervals on top of the bottom formwork 3 along the eaves slope direction. The other end of the water-stop bolt 4 is inserted through the drilled hole in the top formwork 5. The lowest top formwork 5 is aligned with the lowest bottom formwork 3. Supporting top plates 6 are arranged at intervals on top of the top formwork 5. The supporting top plates 6 are fixed to the top formwork 5 with nail guns or screws to reinforce the top formwork 5. Then, a double steel pipe type main keel is erected on top of the supporting top plates 6. The supporting top plates 6 and the double steel pipe type main keel are tied and fixed with lead wire. The top of the water-stop bolt 4 is clamped and fixed to the top double steel pipe keel by a U-shaped clamp. The top formwork 5, bottom formwork 3 and side ribs form a casting cavity 50. The supporting bottom plate 2 and supporting The top plates 6 are all long strips of timber, which facilitates the support and connection of the top formwork 5 and the bottom formwork 3. The two ends of the water-stop bolts 4 can be positioned and fixed to the top formwork 5 and the bottom formwork 3 respectively by means of U-shaped clips, so as to control the thickness of the poured concrete. A water-stop plate is fixed in the middle of the water-stop bolts 4. Then, concrete is poured into the pouring cavity 50 from bottom to top along the inclined direction in the gap between two adjacent sets of top formwork 5. After the concrete in the lower pouring cavity 50 is compacted by vibrating rod, the movable formwork 51 is laid in this gap. After the movable formwork 51 is laid in the gap, a supporting top plate 6 is set on top of the movable formwork 51. The middle of the supporting top plate 6 is fixed to the set of movable formwork 51 by nail gun or screws.The two ends of the supporting top plate 6 are connected and fixed to the supporting top plates 6 of the adjacent top formwork 5 above and below using nail guns or screws, thereby sealing the gaps in the movable formwork 51. Then, concrete is poured into the pouring cavity 50 again through the gaps between the two sets of top formwork 5 above. This process of pouring and laying the movable formwork 51 is repeated, thus pouring the entire sloping roof in stages from bottom to top along the inclined direction. This reduces concrete slippage during pouring, ensures pouring quality, and allows the bottom top formwork 5 and movable formwork 51 to be removed and reused depending on the hardening of the poured concrete. After the roof is poured and formed, the top formwork 5, bottom formwork, and movable formwork 51 are removed, and the exposed bolts at the bottom of the concrete are cut off using a grinder.
