Description

Technical Field

[0001] This application relates to the field of construction auxiliary devices, and in particular to a precast staircase grouting device. Background Technique

[0002] In the field of construction, precast staircases are often used instead of traditional pouring to improve the construction efficiency inside the building. Construction workers hoist and place the precast staircase on the floor slab inside the building, and then fixedly connect the end of the precast staircase to the floor slab to make the precast staircase have better structural strength.

[0003] The relevant precast staircase installation construction is completed by pouring cement mortar. Construction workers set up templates on the floor slab, open pouring holes on the end plates of the precast staircase, cover the end of the precast staircase on the template, so that the cement mortar can be injected into the template through the pouring holes, and then complete the installation of the precast staircase, and fixedly connect the precast staircase to the ground.

[0004] The above-mentioned related technical solutions have the following defects: Before the pouring process, several templates need to be installed on the ground. It is difficult to stably fix the templates on the ground, and it takes a long time to install the brackets of the templates to reinforce the templates. Content of the Utility Model

[0005] In order to conveniently and quickly install the template on the ground, this application provides a precast staircase grouting device.

[0006] A precast staircase grouting device provided by this application adopts the following technical solutions:

[0007] A precast staircase grouting device includes a template, a plurality of screw rods and a plurality of embedded bolts. The embedded bolts are vertically fixed on the ground. One end of the screw rod is connected with a hook, and the other end is connected with the template. The hook is used for hanging on the embedded bolt.

[0008] By adopting the above technical solution, one end of the screw rod is connected to the template, the other end of the screw rod is bent to form a hook, and the hook is hung on the embedded bolt, which can play the role of fixing the template. The user pours cement mortar on one side of the template close to the embedded bolt, so that the template plays the role of blocking the cement mortar and shaping. Construction workers bury the embedded bolts at the predetermined positions on the ground, so that the template can be connected to the embedded bolts, thereby improving the efficiency of fixing the template, making it convenient and quick to install the template on the ground, and improving the work efficiency.

[0009] Optionally, the screw rod penetrates through the template, and a plurality of nuts are threadedly connected to the screw rod, and the plurality of nuts clamp the template.

[0010] By adopting the above technical solution, by passing the screw through the formwork and arranging a plurality of nuts on the screw, the formwork and the screw are detachably connected. After the cement mortar solidifies, the user can remove and recycle the formwork, thereby reducing the construction cost.

[0011] Optionally, the formwork is set as angle iron, and the screw passes through the formwork and is fixed by nuts.

[0012] By adopting the above technical solution, by opening holes in the angle iron and inserting the screw into the angle iron, the angle iron can be fixed on the ground through the hook and block the cement mortar. The cost of the angle iron is relatively low, which can further reduce the pouring cost.

[0013] Optionally, a precast staircase is arranged above the formwork, and a pouring hole is opened in the precast staircase, and the embedded bolt is inserted into the pouring hole.

[0014] By adopting the above technical solution, by opening a pouring hole in the precast staircase, when the construction worker hoists the precast staircase, inserting the embedded bolt into the pouring hole can make the embedded bolt catch the precast staircase. At this time, when the construction worker injects cement mortar into the pouring hole, the cement mortar can fill the space between the precast staircase and the ground. After the cement mortar solidifies, a structural member is formed, and the structural member is inserted into the pouring hole and catches the precast staircase, thereby improving the connection stability between the precast staircase and the ground.

[0015] Optionally, a plurality of support members are arranged between the screws. The support members are arranged on the ground and are used to support the precast staircase.

[0016] By adopting the above technical solution, by arranging support members under the precast staircase, making the support members arranged on the ground and supporting the end plate of the precast staircase, thereby forming a cavity between the precast staircase and the ground. After the cement mortar is poured into the pouring hole, the cement mortar can fill the frame structure surrounded by the formwork, reducing the probability of air bubbles and cracks generated between the ground and the precast staircase, and thereby improving the connection strength between the ground and the precast staircase.

[0017] Optionally, a positioning member is arranged on the screw. The positioning member includes a plurality of cross bars and a plurality of longitudinal bars. The cross bars and the longitudinal bars intersect and are connected to each other. One side of the positioning member is connected to a screw, and the support member is arranged in the space between the cross bar and the longitudinal bar.

[0018] By adopting the above technical solution, by arranging a positioning member on the screw, the positioning member is connected to the screw to keep the position stable. The user evenly arranges a plurality of support members on the positioning member, so that the positioning member can catch the support member. When the precast staircase is covered on the support member, the support member provides uniform support for the precast staircase, thereby improving the structural strength of the precast staircase.

[0019] Optionally, a plurality of hooks are arranged on the positioning member, and the hooks are used for hanging on the screw.

[0020] By adopting the above technical solution, by arranging a hook on the positioning member, the positioning member can be hung between two screw rods through the hook, thereby facilitating the user to connect the positioning member to the screw rod and improving the construction efficiency.

[0021] Optionally, a plurality of templates are provided, and the plurality of templates are spliced with each other. A plurality of hooks are hung on one embedded bolt.

[0022] By adopting the above technical solution, by hanging the hooks of a plurality of screw rods on one embedded bolt, a plurality of templates can be spliced to form a frame structure, thereby reducing the number of embedded bolts set by construction workers on the ground and improving the construction efficiency.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] The embodiment of the present application discloses a grouting device for precast staircases. Referring to Figure 1 and Figure 2 , it includes a formwork 1, a plurality of screws 2 and a plurality of embedded bolts 3. The embedded bolts 3 are vertically arranged on the ground. One end of the screw 2 is connected to the embedded bolt 3, and the other end is connected to the formwork 1. A plurality of formworks 1 can be provided, and the formwork 1 is used to block the cement mortar. The construction worker hoists the precast staircase 4 so that the end of the precast staircase 4 is arranged on the ground. By pouring the cement mortar between the precast staircase 4 and the ground, after the cement mortar solidifies, the ground and the precast staircase 4 are connected, thereby improving the structural stability of the precast staircase 4 installed in the building structure.

[0034] Referring to Figure 1 , a plurality of pouring holes 41 are opened at the end of the precast staircase 4. The pouring holes 41 are vertically opened and penetrate through the precast staircase 4. When the construction worker hoists the precast staircase 4, the embedded bolt 3 is inserted into the pouring hole 41. Then the construction worker injects the cement mortar into the pouring hole 41, so that the cement mortar can flow to the space between the precast staircase 4 and the ground and fill the pouring hole 41. The cement mortar submerges the embedded bolt 3 and solidifies to form a concrete structure. The concrete structure is inserted into the pouring hole 41 and is clamped with the precast staircase 4, improving the connection stability between the precast staircase 4 and the ground.

[0035] Referring to Figure 2 , a hook 21 is fixedly connected to one end of the screw 2, and the end of the screw 2 far from the hook 21 is threadedly connected to the formwork 1. The user horizontally arranges the screw 2 on the ground, and hangs the hook 21 on each screw 2 on an embedded bolt 3, so that the screw 2 can fix the formwork 1. When the precast staircase 4 is covered on the formwork 1 and the cement mortar is poured, the formwork 1 can be kept in a stable position, reducing the probability of cement mortar overflow and leakage.

[0036] Referring to Figure 2, for Template 1, angle iron can be selected. The end of the screw rod 2 penetrates through the angle iron. Two nuts 22 are threadedly connected to the screw rod 2, and the two nuts 22 jointly clamp the angle iron, so that the angle iron is relatively fixed to the screw rod 2. The user sets multiple screw rods 2 at intervals along the length direction of the angle iron, and the multiple screw rods 2 are respectively fixed to the ground through a buried bolt 3, so that the angle iron can maintain better connection strength on the ground.

[0037] In other embodiments, referring to Figure 3 , multiple screw rods 2 are hung on one buried bolt 3. The user sets multiple buried bolts 3 on the ground, so that multiple mutually perpendicular templates 1 can be set on the ground. The templates 1 abut against each other and form a frame structure, further improving the plugging effect on the cement mortar.

[0038] Referring to Figure 4 , a positioning member 5 is arranged on the screw rod 2. Multiple support members 6 are connected to the positioning member 5. The support members 6 are made of materials with better structural strength. The support members 6 are arranged in a columnar structure. The support members 6 are arranged on the ground. When the user hoists the precast staircase 4, the end plate of the precast staircase 4 is covered on the support members 6, which can form a gap between the precast staircase 4 and the ground, and then the cement mortar can fully fill the gap between the precast staircase 4 and the ground, reducing the probability of air bubbles or cracks existing between the precast staircase 4 and the ground.

[0039] Referring to Figure 4 , the positioning member 5 includes multiple cross bars 51 and multiple longitudinal bars 52. The cross bars 51 and the longitudinal bars 52 are perpendicular to each other and connected to each other. The cross bars 51 and the longitudinal bars 52 are spliced to form a mesh structure. The positioning member 5 is installed between two screw rods 2, and multiple support members 6 are inserted into the space between the cross bars 51 and the longitudinal bars 52. When the precast staircase 4 is covered above the support members 6 and the cement mortar is poured, the positioning member 5 is fixed through the screw rod 2, and the support members 6 are stuck under the precast staircase 4 through the positioning member 5, so that multiple support members 6 can evenly support the precast staircase 4, improving the structural strength of the precast staircase 4. The positioning member 5 is buried in the cement mortar, and after the cement mortar solidifies, it forms a reinforced concrete structure with the positioning member 5, further improving the building structural strength.

[0040] Referring to Figure 4 , a hook 53 is arranged on the positioning member 5. The hook 53 is fixed at the end of the cross bar 51 or the longitudinal bar 52. The hook 53 can be hung on the screw rod 2. The cross bar 51 or the longitudinal bar 52 is respectively connected with the hook 53 at both ends, so that the positioning member 5 can be clamped on two screw rods 2, and it is convenient for the user to connect the positioning member 5 between the screw rods 2.

[0041] The implementation principle of the embodiments of this application is as follows: By setting embedded bolts 3 on the ground and connecting a hook 21 to the end of the screw rod 2, the hook 21 can be hung on the embedded bolt 3, so that the formwork 1 can be clamped on the ground through multiple embedded bolts 3. When the construction workers pour cement mortar, the formwork 1 plays the role of sealing the cement mortar. After the cement mortar solidifies, the construction workers can remove and recycle the formwork 1 from the screw rod 2, reducing the construction cost.

[0042] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
